An embodiment of the first aspect of the present invention provides an adjusting structure of a proximity switch 3, as shown in fig. 1, including a cylinder 1 and a locking block 2. The locking block 2 is used for locking the proximity switch 3 on the cylinder body 1. Wherein the locking block 2 is provided with a mounting hole 21 for mounting the proximity switch 3. The proximity switch 3 may be mounted on the locking block 2 through the mounting hole 21, wherein the cylinder 1 is provided with a waist-shaped groove 11, and the waist-shaped groove 11 extends along the axial direction of the cylinder 1, and it should be noted that the waist-shaped groove 11 extends along the axial direction of the cylinder 1, rather than the axial direction in the strict sense, and it is understood that the waist-shaped groove 11 has a certain radian, and the extending direction of the radian is approximately parallel to the axial direction of the cylinder 1, and is not completely coincident. Specifically, the mounting hole 21 extends along the radial direction of the cylinder 1, and the mounting hole 21 and the waist-shaped groove 11 formed in the cylinder 1 are correspondingly arranged, that is, the proximity switch 3 can extend into the waist-shaped groove 11 after being mounted to the mounting hole 21, and after the proximity switch 3 enters the waist-shaped groove 11, the waist-shaped groove 11 can move along the extending direction of the waist-shaped groove 11, that is, along the axial direction of the cylinder 1, so that the adjustment of the position of the proximity switch 3 in the axial direction of the cylinder 1 is realized, and meanwhile, the mounting hole 21 extends along the radial direction of the cylinder 1, and the proximity switch 3 can also move in the direction close to or far away from the cylinder 1 relative to the cylinder 1, so that the adjustment of the position of the proximity switch 3 in the radial direction of the cylinder 1 is realized, and the locking block 2 and the cylinder 1 have simple structure, low processing precision requirements and low processing cost.
It should be noted that the adjustment of the proximity switch 3 in the axial and radial directions of the cylinder 1 is independent of each other, and can be adjusted in both the axial direction and the radial direction, or in any direction, and likewise, when the adjustment is required in both the axial direction and the radial direction, there is no necessary connection between the axial adjustment sequence and the radial adjustment sequence, that is, the adjustment of the axial position and the radial position of the proximity switch 3 is performed independently, and is not affected by each other.
In the related art, in the adjusting process of the proximity switch 3, the axial and radial dual adjustment of the proximity switch 3 cannot be realized, so that the single adjustment axial direction or the radial direction causes errors, and the specific position of the proximity switch induction disc cannot be accurately sensed, thereby affecting the use of the electric spindle. Through the proximity switch 3 adjusting structure that this embodiment provided, when the proximity switch sensing disc 6 produced wearing and tearing or wearing and tearing between the connecting component and lead to the position change and can't accurate sensing signal in the use, accessible latch segment 2 cooperates with cylinder body 1, adjusts proximity switch 3 at cylinder body 1 axial and radial orientation's position to the signal of proximity switch sensing disc is received in the essence.

It should be noted that, in the process of locking the locking block 2 to the cylinder 1 by the first connecting member 4, when the first connecting member 4 is not completely locked, the locking block 2 can perform the swinging operation of the locking block 2 on the cylinder 1 around the first connecting member 4, and when the first connecting member 4 is in the completely locked state, the position of the locking member relative to the cylinder 1 is fixed, and the other end of the locking block 2 is in the non-swinging state.
The second adjusting mechanism comprises a second locking hole 23 arranged on the locking block 2 and a second connecting piece 5, wherein the second connecting piece 5 can penetrate through the second locking hole 23 to lock the proximity switch 3 in a mounting hole 21 of the locking block 2, and the position of the mounting hole 21 is arranged between the first locking hole 22 and the second locking hole 23. And the first locking hole 22 and the second locking hole 23 are provided along the circumferential direction of the cylinder 1 in the same direction as the first cylinder hole 12 and the waist-shaped groove 11 are provided, and the first cylinder hole 12 and the waist-shaped groove 11 are also provided along the circumferential direction of the cylinder 1.
Specifically, the axial position of the proximity switch 3 in the cylinder 1 can be adjusted by matching the first adjusting mechanism with the waist-shaped groove 11, the adjusting process can specifically include that when the axial direction of the proximity switch 3 relative to the cylinder 1 needs to be adjusted, the first connecting piece 4 firstly passes through the first locking hole 22 to enter the first cylinder hole 12, at the moment, the first connecting piece 4 and the first cylinder hole 12 are in a non-fastening state, the locking piece 2 swings around the first connecting piece 4 relative to the cylinder 1, at the moment, the proximity switch 3 is installed in the installation hole 21, and the proximity switch 3 moves in the waist-shaped groove 11 through the swinging locking piece 2, and the axial position relationship is adjusted in the moving process. After the axial positional relationship is determined, the first connecting member 4 is fastened in the first cylinder hole 12 so that the locking member cannot swing relative to the cylinder 1, so that the adjustment of the axial direction position of the proximity switch 3 relative to the cylinder 1 by the first adjustment mechanism is completed.
Specifically, the second adjusting mechanism is matched with the waist-shaped groove 11 to adjust the radial direction position of the proximity switch 3 in the cylinder body 1, the adjusting process specifically includes that when the radial direction of the proximity switch 3 relative to the cylinder body 1 needs to be adjusted, the proximity switch 3 is installed in the installation hole 21 and stretches into the waist-shaped groove 11, the position of the proximity switch 3 close to or far away from the interior of the cylinder body 1 is adjusted, and when the position is adjusted to an exact position, the second connecting piece 5 is locked on the second locking hole 23, so that the radial direction position of the proximity switch 3 relative to the cylinder body 1 is adjusted through the second adjusting mechanism.
Preferably, in the present embodiment, the first connecting piece 4 is locked in the first cylinder hole 12 through the first locking hole 22, the first adjusting mechanism can limit the locking piece 2 in the radial direction of the cylinder 1 on the locking piece 2, and after the first connecting piece 4 passes through the first mounting hole 21 to fasten the first connecting piece 4, the locking piece 2 cannot move in the radial direction of the cylinder 1.
After the second connecting piece 5 locks the locking block 2 through the second locking hole 23, the second adjusting mechanism locks the locking block 2, and the locking block 2 cannot swing along the axial direction of the cylinder body 1, so that the limiting of the locking block 2 in the axial direction of the cylinder body 1 is realized.
Specifically, the first connecting member 4 is fitted into the first cylinder hole 12 through the first locking hole 22, and the axial position of the proximity switch 3 is adjusted by the swing of the waist-shaped groove 11, and after the axial position of the proximity switch 3 is determined, the first adjusting mechanism is locked to fix the axial position of the proximity switch 3.
In a preferred embodiment, the locking block 2 is formed with two oppositely disposed locking plates 24 on a side facing away from the first locking hole 22, and the second locking hole 23 is provided on the locking plates 24, and an adjustment gap is provided between the locking plates 24, the adjustment gap being in communication with the mounting hole 21, the cross-sectional dimension of the proximity switch 3 being adaptable by adjusting the size of the adjustment gap, in particular, the two opposite locking plates 24 being movable in a direction approaching or moving away from each other and being adaptable to different types of proximity switches 3 during the movement in a direction approaching or moving away from each other, while also enabling locking of the proximity switch 3 within the locking block 2.
It will be appreciated that the present construction is applicable to a variety of types of proximity switches 3. The proximity switch 3 is clamped and fixed to the locking block 2 by the second connecting member 5, so that the structure is applicable to not only the proximity switch 3 with external threads, but also the proximity switch 3 without external threads as long as the size of the mounting hole 21 of the proximity switch 3 is suitable.
Specifically, the proximity switch 3 moves in a direction approaching or moving away from the inside of the cylinder 1 in the waist-shaped groove 11 through the mounting hole 21, and when adjusted to a proper position, two locking plates 24 disposed opposite to each other are locked by the second connection member 5 to fix the radial position of the proximity switch 3.
Preferably, the waist-shaped groove 11 is arranged through the cylinder body 1, that is, the waist-shaped groove 11 can penetrate through the wall thickness of the cylinder body 1, so that the waist-shaped groove 11 can move towards the inner direction close to the cylinder body 1, signals sent by the proximity switch sensing disc can be accurately received, meanwhile, the waist-shaped groove 11 is arranged to be in a penetrating structure, interference to the received signals caused by the wall thickness of the cylinder body 1 is avoided, and accordingly stability of the received signals is guaranteed.
Preferably, along the circumferential direction of the cylinder 1, the axis of the first cylinder hole 12 is on the central symmetry plane of the waist-shaped groove 11, that is, the position of the first cylinder hole 12 is not only arranged corresponding to the waist-shaped groove 11, but also arranged at the central position of the waist-shaped groove 11, so that the stress on both sides is uniform when the axial position of the proximity switch 3 is adjusted to the left or right, thereby facilitating the adjustment and the installation of the locking block 2.
In a preferred embodiment, the first cylinder bore 12 is provided with an internal thread and the first connecting piece 4 is provided with an external thread, the internal thread being adapted to the external thread such that the first connecting piece 4 is threadedly connected to the first cylinder bore 12. It will be appreciated that the threaded connection has the advantage that the screwing process of the locking block 2 can be achieved by the first connecting piece 4 being screwed into the first cylinder bore 12 continuously, i.e. the locking block 2 can be swung relative to the cylinder 1 to achieve a position of the proximity switch 3 relative to the cylinder 1 in the axial direction when the first connecting piece 4 is not screwed completely into the first cylinder bore 12.
The second aspect of the present embodiment provides an electric spindle assembly, which includes the adjusting structure for the proximity switch 3 provided in the first aspect, so that all the beneficial technical effects of the first aspect are provided, and will not be described herein.
The electric spindle assembly also comprises a machine body which is fixedly connected with the cylinder body 1; the pull rod is positioned in the machine body, and an induction disc is arranged at one end of the pull rod, which is close to the cylinder body 1; the piston is movably arranged in the cylinder body 1, specifically, the piston can move along the axial direction of the cylinder body 1 and is contacted with one end of the induction disc 6, and the induction disc can be driven to move towards or away from the cylinder body 1; the proximity switch 3 senses the movement position of the sensing disc 6.
The pull rod moves axially under the action of the piston in the rod body, and drives the proximity switch induction disc 6 to displace axially, so that the proximity switch 3 can accurately detect the signal of the proximity switch induction disc 6 and feed the signal back to the system, but the position of the proximity switch 3 needs to be adjusted due to the accumulation of part machining errors and assembly errors and the abrasion deformation of parts in the subsequent use process of the electric spindle, so that the signal of the proximity switch induction disc can be accurately detected.
It will be appreciated that the piston is in contact with the surface of the sensing disc 6, and in the process of moving the piston along the axial direction of the cylinder, the piston can drive the sensing disc 6 to move along the axial direction, the driving is not the driving on the connection relationship, which is equivalent to the driving of the piston pushing against the surface of the sensing disc 6, the piston can push the sensing disc 6 to move, and the end of the pull rod away from the sensing disc 6 is provided with the spring 7.
Specifically, when the piston pushes the sensing disc to move, as shown in fig. 1, the piston pushes the sensing disc 6 and the pull rod to the left (wherein the left means that the piston moves to the left with respect to the position of the cylinder 1, that is, the direction of moving to the outside of the cylinder 1), the spring 7 connected to the pull rod is elastically deformed and is in a compressed state, and at the same time, the sensing disc 6 and the pull rod are pushed by the piston to move together to the left.
When the piston moves to the right (wherein the right indicates the direction of movement relative to the cylinder body position, namely the direction of movement in the cylinder body 1), the external force acting on the sensing disc 6 disappears, namely the external force acting on the spring 7 disappears, and the spring 7 recovers elastic deformation and is in a rebound state, so that the spring 7 drives the pull rod and further drives the sensing disc 6 to move to the right.
It is noted that the terms "left and right" are used above with respect to the orientation of FIG. 1.
Under the state that the first connecting piece 4 is not screwed down, the locking block 2 can drive the proximity switch 3 to swing in the waist-shaped groove 11 relative to the cylinder body 1, and then the purpose of adjusting the axial position of the proximity switch 3 is achieved, after the electric spindle is assembled, the axial position of the proximity switch sensing disc in the clamping states of the loose knife, the broach and the knife-free knife can be adjusted according to the axial position of the proximity switch sensing disc, and after the position adjustment is finished, the first connecting piece 4 is screwed down.
It can be understood that three proximity switch 3 adjusting structures are arranged and are arranged at intervals in the circumferential direction of the cylinder body 1, and the three proximity switch 3 adjusting structures respectively correspond to three states of loose knife, broach and no knife, so that three signals of loose knife, broach and no knife are conveniently received.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that this disclosure is not limited to the particular arrangements, instrumentalities and methods of implementation described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
