In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1 to 8, a description will be given of a clamping mechanism, a processing device and a processing apparatus according to an embodiment of the present application.

A first aspect of the present application provides a clamping mechanism 10 comprising a clamping base 11, a clamping member 12 and a locking mechanism 20.

Specifically, referring to fig. 2 to 4, in the embodiment of the present application, the clamping base 11 may be a rectangular block structure or a square block structure, and for convenience of description, in the embodiment of the present application, the clamping base 11 is described by taking the rectangular block structure as an example, that is, the dimensions of the width direction and the height direction of the clamping base 11 are smaller than the dimensions of the length direction of the clamping base 11, and the dimension of the width direction of the clamping base 11 is smaller than the dimension of the height direction of the clamping base 11.

For convenience of explanation, in the embodiment of the present application, description will be given taking the case where the clamping member 12 is integrally provided with the clamping base 11 as an example, or the clamping base 11 is fixedly connected with one end of the clamping member 12 by a bolt, and the other end opposite to the one end of the clamping member 12 is a free end.

In the embodiment of the present application, the cross-sectional shape of the clamping space 111 may be triangular, quadrangular, and circular. It should be noted that the cross-sectional shape of the clamping space 111 may be determined according to the cross-sectional shape of the clamped portion of the target workpiece, that is, the cross-sectional shape of the clamping space 111 is adapted to the cross-sectional shape of the clamped portion of the target workpiece. For convenience of explanation, in the present application, the cross-sectional shape of the portion to be clamped of the target workpiece is a circle, and the cross-sectional shape of the space of the clamping space 111 is also a circle.

Specifically, the clamping member 12 has an arc structure, and the clamping space 111 includes a first sub-clamping space 111a and a second sub-clamping space 111b, wherein the first sub-clamping space 111a is formed at one side of the clamping base 11 facing the clamping member 12, and the second sub-clamping space 111b is formed at an intrados of the clamping member 12 facing the clamping base 11. The cross-sectional shapes of the first sub-clamping space 111a and the second sub-clamping space 111b are semicircular in the direction perpendicular to the first direction. The first sub-clamping space 111a and the second sub-clamping space 111b are connected end to form a circular clamping space 111.

The clamping space 111 penetrates the clamping base 11 along a first direction, and the first direction is a width direction of the clamping base 11. Because one end of the clamping piece 12 is a free end, and an avoidance space 13 is formed between the free end and the clamping base 11, the avoidance space 13 penetrates through the clamping base 11 along a first direction and a second direction, wherein the first direction and the second direction are mutually perpendicular, and the second direction is a direction which is arranged at an angle with the height direction of the clamping base 11.

Preferably, the second direction is set at an angle of 45 ° with respect to the height direction of the clamping base 11, and the central angle corresponding to the clamping member 12 of the arc structure is greater than or equal to 180 °.

The escape space 13 has a first side wall 112 and a second side wall 121 opposite to and spaced apart from each other, the first side wall 112 being formed at the clamping base 11, and the second side wall 121 being formed at the clamping member 12. When the clamping member 12 is elastically deformed under the action of an external force, the second side wall 121 moves towards the first side wall 112 along the direction perpendicular to the first side wall 112, so as to reduce the avoiding space 13 between the first side wall 112 and the second side wall 121, thereby reducing the second sub-clamping space 111b and further reducing the clamping space 111.

The locking mechanism 20 is slidably connected to the clamping base 11, and the locking mechanism 20 slides along the vertical direction of the clamping mechanism 10 relative to the clamping base 11. When the clamped part of the target workpiece is accommodated in the clamping space 111, the locking mechanism 20 is in abutting fit with the clamping piece 12, and is used for providing an external force directed to the center of the clamping space 111 for the clamping piece 12, because one end of the clamping piece 12 is integrally arranged with the clamping base 11, the other end is a free end, under the action of the external force, the clamping piece 12 elastically deforms towards the inside of the clamping space 111 and extrudes the clamped part of the target workpiece, so that the clamping of the target workpiece is realized.

When the processing is completed on the target workpiece, the lock mechanism 20 is separated from the clamp 12 to cancel the external force, and the clamp 12 is restored to the original shape, thereby unlocking the target workpiece to facilitate the removal of the target workpiece from the clamping space 111.

It should be noted that the maximum diameter of the target workpiece should be smaller than the diameter of the clamping space 111, and the diameter of the clamped portion of the target workpiece should not be smaller than the diameter of the clamping space 111 after the elastic deformation of the clamping member 12.

Compared with the technical scheme of clamping a target workpiece through a plurality of clamping pieces 12 in the prior art, the clamping mechanism 10 provided by the application has the beneficial effects that: according to the clamping mechanism 10 provided by the embodiment of the application, the clamping base 11 and the clamping piece 12 on the clamping mechanism are provided with the clamping space 111, when the clamping piece 12 clamps a target workpiece, the clamping piece 12 is abutted with the clamping piece 12 through the locking mechanism 20, so that the clamping piece 12 is elastically deformed under the action of the external force to reduce the clamping space 111, the target workpiece positioned in the clamping space 111 is clamped and fixed, the stroke distance of the clamping piece 12 is relatively short, the time for clamping the target solid by the clamping mechanism 10 is shortened, and the clamping efficiency of the clamping mechanism 10 on the target workpiece is improved.

In one embodiment of the present application, the locking mechanism 20 includes a locking element 21, a driving element 22 and a telescopic element 23, wherein the locking element 21 is fixedly connected to the telescopic element 23, the telescopic element 23 is slidably connected to the driving element 22, and the driving element 22 is used for driving the telescopic element 23 to drive the locking element 21 to move along the height direction of the clamping base 11, so that the locking element 21 abuts against the clamping element 12 and provides an external force to the clamping element 12.

Specifically, in the embodiment of the present application, the driving member 22 is a cylinder or a hydraulic cylinder, and the telescopic member 23 is a telescopic rod slidably connected to the cylinder or the hydraulic cylinder. The driving member 22 is fixed on one side of the clamping base 11 far from the clamping space 111, and the telescopic member 23 penetrates the clamping base 11 along the height direction of the clamping base 11 and is fixedly connected with the locking member 21, and for convenience of description, in this application, the driving member 22 is taken as an air cylinder for illustration.

The lock 21 has a lock position and an unlock position, and when the lock 21 is in the lock position, the lock 21 abuts against the clamp 12 to supply an external force to the clamp 12; when the lock 21 is in the unlock position, the lock 21 is separated from the clamp 12 to cancel the external force; under the drive of the driving member 22, the telescopic member 23 moves the driving member 22 between the locking position and the unlocking position.

In this application, a first abutment surface 122 is provided on a side of the clamping member 12 facing the locking member 21, a second abutment surface 211 is provided on a side of the locking member 21 facing the clamping member 12, and shapes of the first abutment surface 122 and the second abutment surface 211 are mutually matched. When the locking member 21 is in the locking position, the second abutting surface 211 abuts against the first abutting surface 122, so that an external force is provided to the clamping member 12, and the shapes of the first abutting surface 122 and the second abutting surface 211 are mutually matched, so that the external force can uniformly act on the clamping member 12 when the locking member 21 provides the external force to the clamping member 12. When the lock 21 is in the unlock position, the first abutment surface 122 and the second abutment surface 211 are separated to cancel the external force.

Preferably, in the embodiment of the present application, the clamping member 12 is in an arc structure, the first abutting surface 122 is formed on the outer arc surface of the clamping member 12, the first abutting surface 122 is an arc surface, the second abutting surface 211 is formed on one side of the locking member 21 facing the clamping member 12, the second abutting surface 211 is also an arc surface, and the radian of the first abutting surface 122 is the same as that of the second abutting surface 211, so that the first abutting surface 122 can be better adapted to the second abutting surface 211.

In one embodiment of the present application, the clamping base 11 is provided with a limiting bump 113, when the locking element 21 is in the locking position, the locking element 21 abuts against the limiting bump 113 to limit the locking element 21 to move along the direction of the unlocking position towards the locking position, so as to prevent the locking element 21 from damaging the clamping element 12 due to excessive movement along the direction of the unlocking position towards the locking position.

Preferably, the number of the limiting protrusions 113 is two, the two limiting protrusions 113 are arranged at intervals along the length direction of the clamping base 11, in the two limiting protrusions 113, two sides of each limiting protrusion 113 are provided with a clamping piece 12 and a clamping space 111, and the clamping pieces 12 and the clamping spaces 111 located at two sides of the limiting protrusions 113 are symmetrically arranged about the limiting protrusions 113.

In one embodiment of the application, the clamping mechanism 10 further includes an elastic member 14, wherein one end of the elastic member 14 is fixedly connected to the base, and the other end of the elastic member abuts against the locking member 21, so as to drive the locking member 21 to move from the locking position to the unlocking position.

Preferably, the elastic member 14 is a spring.

Specifically, in the embodiment of the present application, each of the limiting protrusions 113 is provided with a receiving hole 114 opened toward the locking element 21, and the elastic element 14 is received in the receiving hole 114 and extends at least partially to the outside of the receiving hole 114. Under the driving of the driving member 22, the telescopic member 23 drives the locking member 21 to move from the unlocking position to the locking position, and at this time, the elastic member 14 is in abutting engagement with the locking member 21 and is in a compressed state. When the driving member 22 drives the telescopic member 23 to drive the locking member 21 to move from the locking position to the unlocking position, the elastic force of the elastic member 14 cooperates with the driving member 22 due to the compression of the elastic member 14, so that the locking member 21 moves from the locking position to the unlocking position until the elastic member 14 returns to the original length, and the locking member 21 can move to the unlocking position. Meanwhile, when the locking member 21 is located at the locking position, the elastic force generated by the compressed elastic member 14 acts on the locking member 21 to buffer the locking member 21, so that the locking member 21 is prevented from excessively moving in the direction of the unlocking position toward the locking position to damage the surface of the target workpiece to the clamping member 12.

Preferably, in the present application, the number of the elastic members 14 is two, and the number of the accommodating holes 114 is two correspondingly, and the two accommodating holes 114 are arranged at intervals along the width direction of the clamping base 11. The two elastic members 14 are in one-to-one correspondence with the two accommodating holes 114 and accommodated in the accommodating holes 114 corresponding to the two elastic members to realize uniform buffering of the locking member 21.

In a second aspect of the present application, a machining apparatus is provided that includes a clamping mechanism 10, a rotating mechanism 30, an actuator 40, and a control mechanism (labeled in the figures).

Referring specifically to fig. 1 and 5, in an embodiment of the present application, the clamping mechanism 10 is the clamping mechanism 10 provided in any one of the foregoing embodiments.

At the same time, the actuator 40 can be moved in the vertical direction of the machining base 50 toward or away from the machining base 50 so that the milling cutter 41 can approach or move away from the target workpiece and machine the target workpiece.

The processing base 50 is provided with a movable table 51, and the movable table 51 is electrically connected to the control mechanism and is capable of moving in a horizontal direction relative to the processing base 50, such as in a left-right direction and a front-rear direction of the processing base 50, under the control of the control mechanism. The rotating mechanism 30 is fixedly connected to the movable table 51, and is driven by the movable table 51 to move in the horizontal direction along the left-right direction and the front-rear direction of the processing base 50, so that the milling cutter 41 can mill different parts of the target workpiece.

In processing a target workpiece, it is necessary to store a processing program corresponding to the target workpiece in the control means in advance. After the clamping of the target workpiece on the clamping mechanism 10 is completed, the processing button is started, the control mechanism sends control instructions to the rotating mechanism 30, the executing mechanism 40 and the moving workbench 51 according to the processing program, the executing mechanism 40 receives the control instructions and controls the milling cutter 41 to rotate according to the control instructions and move towards the target workpiece, the moving workbench 51 receives the control instructions and drives the clamping mechanism 10 to move in the left-right direction or the front-back direction of the processing base 50 according to the control instructions, and the rotating mechanism 30 receives the control instructions and controls the rotating angle of the clamping mechanism 10 according to the control instructions, so that the processing device can process a plurality of side surfaces of the target workpiece.

When the driving motor drives the turnover driving piece 31 to rotate, the turnover driving piece 31 drives the clamping base 11 and the driven turnover piece 32 to rotate through the supporting piece 34, so that the executing mechanism 40 can process multiple sides of the target workpiece.

It should be noted that the connection lines of the two ends of the clamping base 11 in the length direction and the connection lines of the two opposite ends of the supporting member 34 are parallel or coincident with the rotation axis of the turning driving member 31, so as to ensure the accuracy of the machining of the different sides of the object by the actuator 40. By arranging the flip driving member 31 and the driven flip member 32 at a distance and coaxially, the opposite ends of the supporting member 34 can be supported when the actuator 40 processes the target workpiece, thereby ensuring the stability of the clamping base 11.

In one embodiment of the present application, the turning driving member 31 and the driven turning member 32 are fixedly connected with a clamp pad 35, one of two opposite ends along the length direction of the supporting member 34 is fixedly connected with the clamp pad 35 on the turning driving member 31, and the other end is fixedly connected with the clamp pad 35 on the driven turning member 32.

When the clamping space 111 is fed, the material returning ejector rod 105 is used for positioning a target workpiece in the clamping space 111 corresponding to the material returning ejector rod; when the clamping space 111 is returned, the return ejector rod 105 is used for pushing the target workpiece in the corresponding clamping space 111 to be fed from the feeding end of the clamping mechanism 10.

When the clamping space 111 is fed, the movable workbench 51 drives the clamping mechanism 10 to move towards the direction of the preset supporting block 84, the material returning air cylinder 101 drives the material returning sliding block 102 to move towards the clamping base 11 in the clamping mechanism 10, and the material returning ejector rod 105 moves to a limiting position, wherein the limiting position is positioned at a position, which is spaced from the clamping space 111, of one side of the clamping base 11 towards the material returning ejector rod 105.

One end of the target workpiece, which is away from the feeding ejector rod 93, is in abutting fit with the material returning ejector rod 105 positioned at the limiting position after extending out of the clamping space 111, so that the material returning ejector rod 105 can position the target workpiece.

When the workpiece to be machined is fed into the clamping space 111, the movable table 51 drives the clamping mechanism 10 to move toward the preset supporting block 84 again, so that the clamping mechanism 10 is abutted against the preset supporting block 84, the preset supporting block 84 is spaced from the waiting slot 73, the preset supporting block 84 does not compress the preset spring 83, and the preset supporting block 84 is separated from the driving wrench 742. The material returning cylinder 101 drives the material returning slide block 102 to move towards the clamping base 11, so that the material returning slide block 102 drives the material returning ejector rod 105 to push the processed target workpiece to enter the preset material groove 85 from the clamping space 111, then the target workpiece falls into the blanking chute 841 from the clearance space between the preset supporting block 84 and the material waiting groove 73, and finally the blanking chute 841 is led down, and the target workpiece enters the collecting box.
