Referring to fig. 1 and 2, a tool 10 according to an embodiment of the present invention includes a base 100, a tool holder 200, and a fastener 300. The base 100 has a receiving groove 1110. The tool holder 200 is disposed in the receiving groove 1110. The base 100 includes a first initial state and a first yield state. The fastening member 300 is inserted into the groove walls of the receiving grooves 1110, the fastening member 300 is used to bring the groove walls of the two opposite receiving grooves 1110 close to each other, and the fastening member 300 can transform and maintain the base 100 from the first original state to the first yielding state.

When the base 100 is in the first original state, a gap exists between the tool holder 200 and the groove wall of the receiving groove 1110.

When the base 100 is in the first yielding state, the groove wall of the receiving groove 1110 can contact and press against the tool holder 200.

In the tool 10, the base 100 includes a first original state and a first yielding state, and the fastener 300 is capable of transforming and maintaining the base 100 from the first original state to the first yielding state. When the base 100 is in the first original state, a gap exists between the tool holder 200 and the groove wall of the receiving groove 1110. In this way, the tool holder 200 can be easily installed in the receiving groove 1110 of the base 100. When the base 100 is in the first yielding state, the groove wall of the receiving groove 1110 can contact and press against the tool holder 200. Thus, the tool holder 200 can be kept fixed relative to the accommodation groove 1110 by the friction force generated when the groove wall of the accommodation groove 1110 is pressed against the tool holder 200. That is, the groove wall of the receiving groove 1110 can clamp the tool holder 200, so that the tool holder 200 and the base 100 are relatively fixed, and the tool holder 200 is prevented from shaking relative to the base 100. Furthermore, the stability of the cutter 10 during machining is ensured, the machining quality of the workpiece is ensured, and high-precision machining is facilitated.

With continued reference to fig. 2 in conjunction with fig. 3, in one embodiment, the tool holder 200 includes a second original state and a second yield state. When the groove wall of the receiving groove 1110 presses against the tool holder 200, the tool holder 200 can be transformed from the second original state to the second yield state.

A gap exists between the tool holder 200 in the second original state and the groove wall of the accommodation groove 1110.

The tool holder 200 in the second yield state can be held in contact with the groove wall of the accommodation groove 1110.

Under the pushing action of the groove wall of the accommodating groove 1110, the tool holder 200 can be transformed from the second original state to the second yield state. And the tool holder 200 in the second yield state can be held in contact with the groove wall of the accommodation groove 1110. That is, the tool holder 200 in the second yielding state can eliminate the gap between the groove wall of the accommodation groove 1110 and the tool holder 200, and the tool holder 200 can be in contact with the groove wall of the accommodation groove 1110.

In combination with the above-described embodiments, in other words, the base 100 is capable of transforming from the first original state to the first yield state under the action of the fastener 300. And the groove wall of the receiving groove 1110 can press against the tool holder 200 when the base 100 is in the first yielding state. In this manner, the tool holder 200 can be transformed from the second original state to the second yield state. That is, the tool rest 200 can change its own state according to the change of the state of the base 100 in response to the change of the state of the base 100. Thus, when the base 100 is in the first yield state, the tool holder 200 has a second yield state corresponding to the first yield state to ensure that the tool holder 200 can better contact the base 100. Further, the stability of the position of the tool holder 200 relative to the receiving groove 1110 can be further ensured.

Referring to fig. 2 to 4, in one embodiment, the tool holder 200 includes a fitting member 210 and an adapter member 220 connected to the fitting member 210. The fitting member 210 is disposed in the receiving groove 1110. The adaptor 220 is at least partially positioned outside the receiving channel 1110. The mating member 210 can be transformed from the second original state to the second yield state when the groove wall of the receiving groove 1110 presses the mating member 210. It will be appreciated that the mating element 210 in the second, yielding state has a tendency to move back to the second, original state. That is, the fitting member 210 can apply an elastic restoring force to the groove wall of the receiving groove 1110. In this manner, the positive pressure between the fitting member 210 and the groove wall of the receiving groove 1110 can be increased. Further, the friction force of the relative movement between the engaging member 210 and the groove wall of the receiving groove 1110 can be increased, and the relative movement between the engaging member 210 and the groove wall of the receiving groove 1110 can be avoided. The engaging member 210 may be embodied as an elastic member.

Further, the mating element 210 in the second yield state has a tendency to move back to the second original state. Then, when the tool 10 is processing a workpiece, there is a tendency of separation between the groove wall of the receiving groove 1110 and the mating member 210 due to vibration or movement of the tool 10 itself, and the like, the mating member 210 in the second yield state can be always kept in contact with the groove wall of the receiving groove 1110 based on the above-mentioned tendency of movement. Thus, a gap between the groove wall of the receiving groove 1110 and the engaging element 210 can be avoided, and a relative movement between the engaging element 210 and the groove wall of the receiving groove 1110 can be avoided.

It should be understood that when the tool 10 vibrates to generate an instantaneous gap between the tool holder 200 and the base 100, the engaging element 210 can rapidly compensate the instantaneous gap based on the movement tendency, and thus, the relative movement between the engaging element 210 and the groove wall of the receiving groove 1110 is avoided.

Referring to fig. 4, in one embodiment, a carrier 230 is disposed on the adapter 220 on a side away from the mating member 210. A blade 240 is provided on the carrier 230. The carrier 230 is for carrying a blade 240. The blade 240 is used to machine the workpiece profile. The carrier 230 is adjustably positioned on the adapter 220 to adjust the position of the insert 240 relative to the tool holder 200. After the carrier 230 is moved to a desired position relative to the adaptor 220, the carrier 230 is locked, thus enabling the tool 10 to accommodate different sizes and types of workpieces.

In one embodiment, the carrier 230 is connected to the adapter 220 in the form of a dovetail structure and dovetail grooves, for example. The movement of the carrier 230 relative to the adaptor 220 can be limited by the dovetail grooves to ensure the accuracy of the movement of the carrier 230. In this embodiment, the locking manner of the supporting member 230 may be specifically that a fastening bolt (not shown, the same applies below) is disposed on a side of the supporting member 230 away from the adaptor 220, the adaptor is formed with a fastening hole for engaging with the fastening bolt, the fastening bolt penetrates through the supporting member 230 and extends to the adaptor 220, and the fastening bolt can engage with a hole wall of the fastening hole.

Of course, the connection manner and the fixing manner between the carrier 230 and the adaptor 220 may be set to other connection manners according to requirements, and are not limited herein.

Referring to fig. 5 and fig. 6 in combination with fig. 2, in one embodiment, a pushing surface 1113 is disposed on a wall of the accommodating groove 1110. The tool holder 200 is provided with a first mating surface 211 slidably mating with the pushing surface 1113. The pushing surface 1113 is configured to push against the first mating surface 211 when the base 100 is transformed from the first original state to the first yielding state. The tool holder 200 can be driven by the pressing surface 1113 to move from the first position to the second position. The groove wall of the receiving groove 1110 is used for pressing against the tool holder 200 when the tool holder 200 moves from the first position to the second position. It is understood that the first position and the second position of the tool holder 200 are two different positions relative to the base 100. The tool holder 200 is shown in a first position relative to the base 100 in fig. 5, and the tool holder 200 is shown in a second position relative to the base 100 in fig. 6. The direction in which the tool holder 200 moves from the first position to the second position is shown in the positive direction of the Z-axis in fig. 5 and 6.

Specifically, under the action of the fastener 300, the base 100 can be transformed from the first original state to the first yielding state, and at this time, the abutting surface 1113 on the receiving groove 1110 can abut against the tool holder 200 under the action of the fastener 300. Thus, the tool holder 200 can be moved from the first position to the second position.

As the tool holder 200 moves from the first position to the second position, the groove wall of the receiving groove 1110 gradually contacts and presses against the tool holder 200. Thus, the tool holder 200 can be transformed from the second original state to the second yield state by the pressing action of the base 100. So that the tool holder 200 can be stably contacted with the groove wall of the receiving groove 1110 to ensure that the position of the tool holder 200 and the position of the base 100 are relatively stable. It will be appreciated that the movement of the tool holder 200 from the first position to the second position is a change of the tool holder 200 from the second original condition to the second yield condition.

Specifically, the pushing surface 1113 is disposed to incline with respect to the groove wall of the accommodating groove 1110. Thus, when the pushing surface 1113 moves due to the deformation of the base 100, the pushing surface 1113 can push the tool holder 200 to move the tool holder 200 from the first position to the second position.

It should be understood that the second yield condition in the various embodiments does not refer to a particular condition of the tool holder 200, and that the second yield condition is a condition in which the tool holder 200 is deformed to some extent relative to a second original condition. The second original state may be a state in which the tool holder 200 is not subjected to an external force, or a state in which the tool holder 200 is located when the base 100 is not pressed against the tool holder 200 by the driving of the fastener 300.

Referring to fig. 7 in conjunction with fig. 4, in one embodiment, the wall of the receiving groove 1110 is further provided with an abutting surface 1114. The tool holder 200 is provided with a second engagement surface 212 engageable with the abutment surface 1114. The abutting surface 1114 and the abutting surface 1113 are sequentially arranged in a direction pointing to the second position along the first position. The abutting surface 1114 and the abutting surface 1113 are both inclined relative to the groove wall of the accommodating groove 1110, and the inclination degree of the abutting surface 1114 and the abutting surface 1113 relative to the groove wall of the accommodating groove 1110 is different.

When the tool holder 200 is located at the second position, the abutting surface 1113 can keep in contact with the first mating surface 211, and the abutting surface 1114 can keep in contact with the second mating surface 212. In other words, when the tool holder 200 is located at the second position, the abutting surface 1113 and the abutting surface 1114 can simultaneously maintain contact with the tool holder 200.

The abutting surface 1114 and the abutting surface 1113 are sequentially arranged in a direction pointing to the second position along the first position. In the above embodiment, when the tool holder 200 is located at the second position, the abutting

surfaces

1113 and 1114 respectively contact and cooperate with the tool holder 200, so as to further limit the relative position between the tool holder 200 and the base 100, and further prevent the tool holder 200 from moving relative to the base 100.

Referring to fig. 7, in one embodiment, the walls of the receiving cavity 1110 include a bottom wall 1118 and a first wall 1115 and a second wall 1116 connected to opposite sides of the bottom wall 1118. First slot wall 1115 and second slot wall 1116 are disposed opposite to each other. The first groove wall 1115, the second groove wall 1116 and the bottom wall 1118 collectively define the receiving groove 1110. The first groove wall 1115 and the second groove wall 1116 are formed with connecting holes 130. Connection hole 130 passes through first slot wall 1115 and/or second slot wall 1116. A fastener 300 is movably disposed through the connecting aperture 130, and adjustment of the fastener 300 may be used to bring the first and

second slot walls

1115, 1116 closer to one another. It is understood that the connection hole 130 may pass through both the first groove wall 1115 and the second groove wall 1116. Alternatively, the connection hole 130 on the first groove wall 1115 penetrates through the first groove wall 1115, and the connection hole 130 on the second groove wall 1116 is a blind hole. And vice versa, will not be described in detail.

Specifically, the process of first groove wall 1115 and second groove wall 1116 approaching each other is the process of changing base 100 from the first original state to the first yielding state. For convenience of illustration, reference will be made to second slot wall 1116 as an example, and first slot wall 1115 is located adjacent to second slot wall 1116.

When the first groove wall 1115 approaches the second groove wall 1116, the pushing surface 1113 pushes the first mating surface 211, so that the tool holder 200 moves from the first position to the second position. In other words, the approach of first slot wall 1115 to second slot wall 1116 is the movement of tool holder 200 from the first position to the second position, i.e., the transition of tool holder 200 from the second original condition to the second yield condition.

Further, for ease of illustration, first slot wall 1115 is adjacent to second slot wall 1116 in the direction of arrow M in fig. 7; second slot wall 1116 is illustrated as being adjacent to first slot wall 1115 along the N arrow in fig. 7. When the first groove wall 1115 and the second groove wall 1116 approach each other along the arrows M and N in fig. 7, respectively, the other groove walls of the receiving groove 1110 approach and press against the tool holder 200 in the same or similar directions. That is, in the present embodiment, the base 100 can press and clamp the tool holder 200 from two opposite directions. Referring to fig. 3 in combination with the above embodiments, the mating member 210 is an elastic body, the mating member 210 can be transformed from the second original state to the second yielding state by the groove wall of the receiving groove 1110, and the mating member 210 in the second yielding state has a tendency to return to the second original state. In other words, when the mating member 210 is transformed from the second original state to the second yield state by the clamping force in the above-mentioned two opposite directions, the mating member 210 as a whole has a tendency to return to the second original state. Thus, the fitting member 210 can not only be in pressing contact with the groove wall of the receiving groove 1110 from the above two opposite directions, but the fitting member 210 can also be in contact with and pressed against the groove wall of the receiving groove 1110 from other directions based on the elastic recovery tendency of the fitting member 210. Furthermore, the pressing force between the tool holder 200 and the groove wall of the accommodating groove 1110 can be more balanced and stable, so that the tool 10 can avoid a gap between the tool holder 200 and the base 100 under vibration in all directions. It will be understood that since the pressing forces between the holder 200 and the groove wall of the receiving groove 1110 are mutually different, that is, the pressing force of the engaging element 210 against the groove wall of the receiving groove 1110 and the pressing force of the engaging element 210 against the groove wall of the receiving groove 1110 are not contradictory.

Referring to fig. 7 in conjunction with fig. 3, in one embodiment, the first groove wall 1115 and the second groove wall 1116 are both provided with a pushing surface 1113; the first groove wall 1115 and the second groove wall 1116 are both provided with a pushing surface 1113. Correspondingly, the two opposite side surfaces of the tool holder 200 are provided with first engaging surfaces 211 engaged with the pushing surfaces 1113. Since first slot wall 1115 is opposite second slot wall 1116. Thus, the pushing surfaces 1113 on the first and

second groove walls

1115, 1116 can push against the first mating surfaces 211 on the two opposite sides of the tool holder 200 together, so as to ensure that the tool holder 200 can move from the first position to the second position. Similarly, the two opposite side surfaces of the tool holder 200 are provided with second mating surfaces 212 that mate with the abutting surfaces 1114. Thus, the engagement between the contact surface 1114 and the contact surface 1113 can further limit the relative position between the tool holder 200 and the base 100, thereby further preventing the tool holder 200 from moving relative to the base 100.

Referring to fig. 7 in conjunction with fig. 8, in one embodiment, when the pushing surface 1113 of the first groove wall 1115 contacts and pushes against the first mating surface 211, the pushing surface 1113 applies a force to the first mating surface 211F 1; similarly, the pushing surface 1113 of the second groove wall 1116 applies a force in the direction of the first mating surface 211F 2. F1 has component forces F12 and F11 in the Y-axis and Z-axis directions respectively; f2 has component forces F22 and F21 in the Y-axis and Z-axis directions, respectively. f12 and f22 can be mutually offset, and f11 and f22 can act on the tool holder 200 together through the first mating surface 211 to move the tool holder 200 from the first position to the second position along the Y-axis direction. Further, the tool holder 200 can be transformed from the second original state to the second yield state by the groove wall of the receiving groove 1110. It can be understood that the pushing surface 1113 of the first groove wall 1115 and the pushing surface 1113 of the second groove wall 1116 respectively act on two first mating surfaces 211 oppositely disposed on the tool holder 200.

Further, referring to fig. 9 and 10, when the abutting surface 1114 on the first groove wall 1115 contacts and abuts against the second mating surface 212, the abutting surface 1114 exerts a force on the second mating surface 212T 1; similarly, the abutment surface 1114 on the second groove wall 1116 applies a force in the direction of the second mating surface 212T 2. T1 has component forces T12 and T11 in the Y-axis and Z-axis directions respectively; t2 has components T22 and T21 in the Y-axis and Z-axis directions, respectively. It will be appreciated that when the tool holder 200 is in the first position, the abutment surface 1114 is not in contact with or at least partially out of contact with the second mating surface 212 due to the gap between the tool holder 200 and the base 100, i.e., the abutment surface 1114 does not affect the movement of the tool holder 200 or only has a minor effect on the movement of the tool holder 200. Further, when the tool holder 200 is located at the second position, the abutting surface 1113 and the abutting surface 1114 can simultaneously maintain contact with the tool holder 200. Therefore, t12 and t22 cancel each other out, and the resultant force of t11, t22 and gravity can cancel out the resultant force of f11 and f 22. Therefore, the tool holder 200 can be kept stationary with the base 100, i.e. the tool holder 200 is locked to the base 100.

Referring to fig. 11, in one embodiment, the fastening member 300 includes a fixing portion 310 and a connecting portion 320 connected to the fixing portion 310. The fixing portion 310 abuts against the base 100. The connecting portion 320 is movably disposed through the connecting hole 130. The hole wall of the connection hole 130 is provided with an internal thread structure. The fastener 300 is provided with an external thread structure engaged with the internal thread structure. Link 320 can rotate to bring first slot wall 1115 and second slot wall 1116 closer together.

Specifically, the fixing portion 310 may abut against a side of the first groove wall 1115 away from the second groove wall 1116. The fastener 300 can rotate relative to the coupling hole 130. As fastener 300 is rotated in its entirety, coupling 320 is threadably engaged to transfer rotational motion to second slot wall 1116 such that second slot wall 1116 approaches and moves away from first slot wall 1115. At this time, the hole walls of the connection holes 130 may be all provided with internal thread structures, or only the hole walls of the connection holes 130 opened on the second groove wall 1116 may be provided with internal thread structures. Since the fixing portion 310 abuts against the side of the first groove wall 1115 away from the second groove wall 1116, one end of the fixing portion 310 is fixed relative to the first groove wall 1115. Thus, the drive connection via the threaded configuration enables second slot wall 1116 to move toward or away from first slot wall 1115. It will be appreciated that this is movement in the direction of the N arrow or opposite to the N arrow in fig. 7.

It should be appreciated that retainer 310 may abut a side of second slot wall 1116 remote from first slot wall 1115. Correspondingly, an internal thread structure may be provided only on the hole wall of the connection hole 130 formed on the first groove wall 1115. The function is the same as above, and will not be described again.

Referring to fig. 7 in conjunction with fig. 3 and 4, in one embodiment, the receiving groove 1110 includes a first inner cavity 1111 and a second inner cavity 1112. The first lumen 1111 communicates with the second lumen 1112. The wall of the second lumen 1112 is connected to the wall of the first lumen 1111. Fitting 210 is disposed within first interior chamber 1111. The shape of the first inner cavity 1111 matches the shape of the fitting element 210, and the pressing of the cavity wall of the first inner cavity 1111 against the fitting element 210 can transform the fitting element 210 from the second original state to the second yielding state. Because the shape of first inner cavity 1111 matches the shape of fitting element 210, fitting element 210 is able to maintain a larger contact area with the cavity wall of first inner cavity 1111 when fitting element 210 is in the second yield state. In this way, relative movement between the tool holder 200 and the base 100 can be further prevented.

Specifically, as first slot wall 1115 approaches second slot wall 1116 in the direction of the M arrow, and second slot wall 1116 approaches first slot wall 1115 in the direction of the N arrow, the walls of first cavity 1111 will move. Thus, the space in the first inner cavity 1111 will be reduced, and the cavity wall of the first inner cavity 1111 can gradually contact and press against the tool holder 200, so that the tool holder 200 is transformed from the second original state to the second yield state. Since the shape of the first lumen 1111 matches the shape of the fitting member 210. So configured, the seat 100 in the first yielding state can be relatively fittingly sleeved on the tool holder 200 in the second yielding state, i.e. the cavity wall of the first inner cavity 1111 can be relatively fittingly sleeved on the mating member 210. Further, the wall of the first inner cavity 1111 can be ensured to have good contact with the mating member 210, so as to prevent the tool holder 200 from moving relative to the base 100.

Referring again to fig. 3, further, the wall of the first lumen 1111 may include an arcuate inner surface and the engagement member 210 may include an arcuate outer surface that mates with the arcuate inner surface. Thus, when the supporting surface 1113 supports against the first mating surface 211 to move the tool holder 200 from the first position to the second position, the outer arc surface of the mating member 210 can contact with, press against, and slide relative to the inner arc surface of the cavity wall of the first inner cavity 1111. Thus, the fitting member 210 can be transformed from the second original state to the second yield state under the pressing and guiding effects of the arc-shaped inner surface. The deformation direction of the fitting member 210 guided by the arc-shaped inner surface can be referred to as reference Q in fig. 3. The above-mentioned arc-shaped inner surface is referred to as reference R in fig. 7; the curved inner surface can be seen as reference S in fig. 4.

It is understood that the shape of the first inner cavity 1111 matches the shape of the fitting member 210, and the shape of the first inner cavity 1111 is not limited to be identical to the outer shape of the fitting member 210. The shape of the first inner cavity 1111 matches the shape of the fitting member 210 means that: when the base 100 is in the first yielding state and the fitting member 210 is in the second yielding state, the cavity wall of the first inner cavity 1111 can be relatively fitted over the fitting member 210. That is, the wall of first lumen 1111 can have a larger contact area with mating element 210. Since the base 100 can be transformed from the first original state to the first yielding state and the tool holder 200 can be transformed from the second original state to the second yielding state, the base 100 and the tool holder 200 have a certain deformation capability. It is easier to match the shape of the first inner cavity 1111 with the shape of the fitting element 210 by arranging the shape of the first inner cavity 1111 identical to the outer shape of the fitting element 210.

It should be emphasized that the descriptions of the first and second yielding states in the embodiments do not limit the base 100 and the tool holder 200 to be elastic members. For convenience of explanation, the base 100 is taken as an example. The gap between the base 100 and the tool holder 200 is generated based on manufacturing, machining, or human reservation, i.e., the gap between the base 100 and the tool holder 200 is often small. Thus, the base 100 is able to transition between the first, original state and the first, yield state within the elastic limits of its material. That is, in the embodiments, the material of the base 100 is not limited to the material with higher elasticity with respect to the first original state and the first yielding state of the base 100. Similarly, the principles described above are also applicable to the tool holder 200.

In one embodiment, the material of the base 100 and the tool holder 200 may be metal, for example. The following description will be given taking the holder 200 as a metal material. When the tool holder 200 is transformed from the second original state to the second yielding state under the pressing action of the groove wall of the receiving groove 1110, the clearance between the tool holder 200 and the base 100 is small, that is, the deformation of the tool holder 200 is small. So as not to cause permanent deformation of the tool holder 200. In other words, since the gap between the tool holder 200 and the base 100 is small, the tool holder 200 is not deformed beyond the elastic limit (or elastic limit) of the material, or the tool holder 200 is prevented from being deformed beyond the elastic limit of the material by manual control. Thus, when the pressing force of the groove wall of the accommodating groove 1110 disappears, the tool holder 200 can be restored to the original shape. I.e., the tool holder 200 is able to return from the second yield state to the second original state. That is, the second yield state described in the embodiments has a tendency to revert to the second original state.

With continued reference to fig. 7 in conjunction with fig. 1 and 4, in one embodiment, the fastener 300 is disposed through the cavity walls of the second inner cavities 1112, and the fastener 300 is used to bring the cavity walls of the two opposite second inner cavities 1112 close to each other. The walls of the first lumen 1111 are capable of moving with the walls of the second lumen 1112. Because the cavity walls of first inner cavity 1111 are capable of moving with the cavity walls of second inner cavity 1112, when fastener 300 brings the cavity walls of the opposing second inner cavity 1112 into proximity with each other, the opposing cavity walls on first inner cavity 1111 are also capable of coming into proximity with each other. Further, the cavity wall of the first inner cavity 1111 can press against the tool holder 200.

The fastener 300 is inserted into the wall of the second inner cavity 1112, and the fitting element 210 is disposed in the first inner cavity 1111. In this manner, the movement of the fastener 300 can be prevented from interacting with the movement of the first inner cavity 1111 against the press-fit element 210.

It is understood that in the above embodiment, the first inner cavity 1111 includes a first cavity wall 1111a and a second cavity wall 1111b oppositely disposed. The second lumen 1112 includes third and

fourth lumen walls

1112a and 1112b disposed opposite one another. The first chamber wall 1111a is connected to the third chamber wall 1112a and the second chamber wall 1111b is connected to the fourth chamber wall 1112 b. First slot wall 1115 includes a first cavity wall 1111a and a third cavity wall 1112 a. The second slot wall 1116 includes a second cavity wall 1111b and a fourth cavity wall 1112 b. First slot wall 1115 is disposed opposite second slot wall 1116.

Referring to fig. 4 and 7, in one embodiment, the fitting member 210 is also provided with a connecting hole 130. The connection hole 130 penetrates the fitting 210. One end of the fastener 300 abuts against the side of the third cavity wall 1112a away from the fourth cavity wall 1112b, and the other end of the fastener 300 passes through the connecting hole 130 on the fitting 210 and extends into the connecting hole 130 on the fourth cavity wall 1112 b. In this manner, the engagement member 210 can be prevented from interfering with the rotation of the fastener 300.

First slot wall 1115 includes one of the cavity walls of second lumen 1112, and first slot wall 1115 also includes one of the cavity walls of first lumen 1111 that is coupled to the cavity wall of second lumen 1112. The second slot wall 1116 includes the other side wall of the second lumen 1112, and the second slot wall 1116 further includes one of the walls of the first lumen 1111 that is connected to the wall of the second lumen 1112. It should be emphasized that first slot wall 1115 is disposed opposite second slot wall 1116.

Referring to fig. 4 again, in an embodiment, the tool holder 200 is formed with a first deformation groove 213. The opposite sidewalls of the first deformation groove 213 can approach each other when the tool holder 200 is transformed from the second original state to the second yield state. In other words, the in-groove space of the first deformation groove 213 decreases when the tool holder 200 is transformed from the second original state to the second yield state. Thus, a space can be provided for deformation of the tool holder 200. Specifically, the first deformation groove 213 opens on the fitting 210.

Referring to fig. 13 in conjunction with fig. 4, in one embodiment, the tool 10 further includes an adjustment member 400. The tool holder 200 is provided with an adjusting hole 520. The adjusting member 400 is provided with an external thread structure. The wall of the adjusting hole 520 is provided with an internal thread engaged with the external thread structure. The adjusting member 400 is used to drive the tool holder 200 to move relative to the base 100 when moving. In this manner, the position of the tool holder 200 relative to the base 100 can be adjusted by the adjustment member 400 so that the tool 10 can accommodate workpieces of different sizes. The moving direction of the tool holder 200 relative to the base 100 is shown in the direction of the X-axis in fig. 12. That is, the position of the tool holder 200 in the X-axis direction with respect to the base 100 can be adjusted by the adjuster 400.

It can be understood that the adjusting member 400 is used to adjust the position of the tool holder 200 relative to the base 100 when the base 100 is in the first original state. That is, the adjusting member 400 is used to adjust the position of the tool holder 200 relative to the base 100 when the groove wall of the receiving groove 1110 has not clamped the tool holder 200. When the base 100 is in the first yielding state, i.e. the groove wall of the receiving groove 1110 clamps the tool holder 200, the internal thread structure on the hole wall of the adjusting hole 520 can press the external thread structure on the adjusting member 400 under the action of the groove wall of the receiving groove 1110. So set up, can be dead with regulating part 400 relative regulation hole 520 lock, regulating part 400 relative regulation hole 520's pore wall removes. Accordingly, by clamping the base 100 to the tool holder 200, it is possible to avoid the position of the tool holder 200 from being changed due to an erroneous operation. On the other hand, by clamping the base 100 to the tool holder 200, it is possible to prevent the internal thread structure and the external thread structure from being damaged by an erroneous operation such as an excessive driving force applied to the adjuster 400.

Referring to fig. 13 in conjunction with fig. 4, in one embodiment, the tool holder 200 further includes an intermediate member 500. The intermediate member 500 is connected with the fitting 210. The adjustment hole 520 is opened on the intermediate member 500. The wall of the adjustment hole 520 is provided with an internal thread which is engaged with the external thread structure of the adjustment member 400. That is, the adjusting member 400 is rotatably coupled to the fitting member 210 through the intermediate member 500. With this arrangement, the intermediate member 500 can be manufactured without being affected by the material of the fitting member 210 and the accuracy of the processing of the fitting member 210. Specifically, since the intermediate member 500 is provided separately from the fitting member 210, the material of the intermediate member 500 may be provided with better mechanical properties so as to transmit the movement with the adjusting member 400 to the fitting member 210 through the intermediate member 500.

Furthermore, the fitting 210 has a fitting hole 214, and a hole wall of the fitting hole 214 is sleeved on the intermediate member 500. When the fitting member 210 is transformed from the second original state to the second yielding state, the intermediate member 500 can also be transformed to the yielding state by the pressing action of the hole wall of the fitting hole 214. In this manner, the internal thread structure on the wall of the adjusting hole 520 can clamp the external thread structure on the adjusting member 400, so that the adjusting member 400 is locked.

Referring to fig. 13 in combination with fig. 4, in an embodiment, the intermediate member 500 further has a second deformation groove 510, and when the tool holder 200 is transformed from the second original state to the second yield state, two opposite sidewalls of the second deformation groove 510 can approach each other. Similar to the first deformation groove 213, when the fitting 210 is transformed from the second original state to the second yielding state, the wall of the fitting hole 214 presses against the outer wall of the middle piece 500. Thus, opposite sidewalls of the second deforming groove 510 can be close to each other, that is, the in-groove space of the second deforming groove 510 is reduced. Thus, a space can be provided for deformation of the tool holder 200.

Referring to fig. 7 again, in one embodiment, the wall of the receiving groove 1110 is formed with a weakening groove 1117. It can be understood that, at the same position on the groove wall of the accommodating groove 1110, the groove wall provided with the weakening groove 1117 has a smaller thickness than the groove wall not provided with the weakening groove 1117. Under the same other conditions, the force with which the structure with a smaller thickness is deformed is also smaller than that with the structure with a larger thickness. Thus, compared to the case where the weakening groove 1117 is not formed, the formation of the weakening groove 1117 on the groove wall of the accommodating groove 1110 can facilitate the base 100 to be converted from the first original state to the first yielding state. Thus, it is more convenient to eliminate the gap between the tool holder 200 and the base 100 by the fastener 300. The weakening groove 1117 may be formed in the wall of the first inner cavity 1111, for example.

In one embodiment, the number of weakening grooves 1117 may be plural. A plurality of weakening grooves 1117 are spaced from the wall of the first inner chamber 1111.

The processing equipment (not shown, the same applies below) provided by an embodiment of the present invention is used for processing a workpiece. The machining apparatus includes a tool 10, a fixing jig (not shown, the same applies below), and a driving mechanism (not shown, the same applies below). The fixing jig is used for keeping the position of the workpiece relatively fixed. A drive mechanism is coupled to the tool 10 for driving the tool 10 relative to the workpiece. In this manner, the position of the tool 10 relative to the workpiece can be controlled by the drive mechanism to machine the workpiece as desired.

In other embodiments, the drive mechanism may also be coupled to the stationary fixture for driving movement of the workpiece relative to the tool 10. In this manner, the workpiece can be moved to the appropriate station as required to machine the workpiece with the tool 10.

In one embodiment, base 100 includes a clamping portion 110 and a tool shank 120 coupled to clamping portion 110. The receiving groove 1110 is opened on the clamping portion 110. The tool shank 120 is connected to a drive mechanism. The drive mechanism, via the tool shank 120, can control the spatial position of the tool holder 200 and the structure carried on the tool holder 200. Specifically, the connection mode of the tool holder 120 and the driving mechanism may be a shaft hole connection, an inner cone-outer cone connection, or the like. Of course, the connection mode between the tool holder 120 and the driving mechanism may be other connection modes according to requirements, and is not limited herein.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
