Technical Field

Background

In the field of machining technology, a workpiece or a workpiece transfer rack or the like is fixed by a clamping device. The existing clamping device adopts two sets of oppositely arranged cylinders to realize the clamping function, and the problem of the clamping device is that: the first is that the stroke of the air cylinder is fixed, and the stroke of the air cylinder can be adjusted properly according to the position of a workpiece or a transfer frame during the process of installing the two groups of air cylinders. If the stroke of the air cylinders cannot be adjusted, the risk that the workpiece or the transfer rack is damaged due to the fact that the stroke of the air cylinders is too long in the clamping process of the two groups of air cylinders possibly exists, or when the size of the workpiece or the size of the transfer rack is changed, the relative positions of the two groups of air cylinders need to be adjusted again; secondly, if the cylinder continues to work at full load, namely when the piston rod of the cylinder continues to work at the maximum stroke, the airtightness of the air tightness mechanism of the cylinder can be reduced, so that the service life of the cylinder is shortened.

For example, in the production and processing process of solar silicon wafers, after the solar silicon wafers are sliced, the solar silicon wafers need to be cleaned, a silicon wafer inserting machine inserts a silicon wafer into a loading basket, then the loading basket with the silicon wafers is placed into silicon wafer sorting equipment for sorting, and in the process, a cylinder type clamping device is generally adopted to clamp the loading basket. Because the stroke of cylinder is fixed, the clamping device who is difficult to change the cylinder stroke causes easily that the loading basket warp and produce positional deviation, causes the insertion machine card at last, and insertion machine production efficiency reduces. In addition, if the air cylinder of the clamping device is continuously operated at the maximum stroke, the airtightness of the air-tight mechanism of the air cylinder is reduced, and it is also difficult to clamp the loading basket at this time.

Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating a clamping device according to an embodiment of the present invention, where the clamping device according to an embodiment of the present invention includes: a first cylinder 100, a second cylinder 200, a first clamping assembly 300, a second clamping assembly 400, and a first adjustment assembly 500. The first air cylinder 100 and the second air cylinder 200 are oppositely arranged, a piston rod of the first air cylinder 100 drives the first clamping assembly 300 to move, a piston rod of the second air cylinder 200 drives the second clamping assembly 400 to move, and when the first clamping assembly 300 and the second clamping assembly 400 move oppositely, a clamping function can be achieved. The first adjustment assembly 500 is disposed on the first cylinder 100, and achieves stroke adjustment of the first cylinder 100 by limiting movement of a piston rod of the first cylinder 100. In addition, the first adjusting assembly 500 limits the movement of the piston rod of the first cylinder 100, so that the first cylinder 100 can be prevented from continuously working at the maximum stroke, and the working life of the first cylinder 100 is prolonged.

Specifically, the first clamping assembly 300 is detachably connected with, for example, screwed to, the piston rod of the first cylinder 100, and the piston rod of the first cylinder 100 moves to drive the first clamping assembly 300 to move; the second clamping assembly 400 is detachably connected with, for example, screwed to the piston rod of the second cylinder 200, the piston rod of the second cylinder 200 drives the second clamping assembly 400 to move when moving, and the first clamping assembly 300 and the second clamping assembly 400 can perform a clamping function when moving towards each other. The first clamping assembly 300 and the second clamping assembly 400 are detachably connected respectively, and the purpose is to facilitate replacement of different clamping assemblies so as to meet different clamping scenes.

The first adjusting assembly 500 includes a first adjusting block 510 and a second adjusting block 520, wherein the first adjusting block 510 includes a first limiting portion 511, and the second adjusting block 520 includes a second limiting portion 521. In the axial direction of the piston rod of the first cylinder 100, the first adjusting block 510 is adjustably disposed on the outer wall of the first cylinder 100, for example, the outer wall of the first cylinder 100 is provided with a plurality of threaded holes along the axial direction of the piston rod, and meanwhile, the first adjusting block 510 is also provided with corresponding threaded holes, and the position adjustment of the first adjusting block 510 is realized by the alignment of the threaded holes at different positions; or the first adjusting block 510 is provided with a slider, and the outer wall of the first cylinder 100 is provided with a slide rail. When the stroke of the first cylinder 100 needs to be adjusted, the first adjusting block 510 can move relative to the outer wall of the first cylinder 100, and after the adjustment is finished, the first adjusting block 510 is fixed on the outer wall of the first cylinder 100 in a threaded connection mode. Second adjustment block 520 is removably coupled, e.g., threadably coupled, to first clamp assembly 300. When the piston rod of the first cylinder 100 drives the first clamping assembly 300 to move, the movement of the first clamping assembly 300 can drive the second adjusting block 520 to move. When the second adjustment block 520 moves in the direction of the second cylinder 200, the second stopper 521 can interfere with the first stopper 511, and the first stopper 511 restricts the movement of the second stopper 521. That is, in the process that the second stopper 521 moves along with the piston rod of the first cylinder 100, the first stopper 511 fixed to the outer wall of the first cylinder 100 may interfere with the second stopper 521, thereby restricting the piston rod of the first cylinder 100 from continuing to move in the direction of the second cylinder 200.

The working principle of the clamping device in the embodiment is as follows: in the operation of the clamping device, the piston rod of the first air cylinder 100 drives the first clamping assembly 300 to move, the piston rod of the second air cylinder 200 drives the second clamping assembly 400 to move, and the first clamping assembly 300 and the second clamping assembly 400 can realize a clamping function in the process of moving towards each other. When the piston rod of the first cylinder 100 moves, the first clamping assembly 300 can be driven to move, and meanwhile, the second adjusting block 520 on the first adjusting assembly 500 is driven to move, and the second limiting part 521 on the second adjusting block 520 also moves along with the second adjusting block 520. In this process, the first regulation block 510 disposed on the outer wall of the first cylinder 100 is kept stationary, and during the movement of the second regulation block 520 to the second cylinder 200, the first stopper portion 511 disposed on the first regulation block 510 can interfere with the second stopper portion 521 while restricting the movement of the second regulation block 520. Since the second adjusting block 520 is fixedly connected to the piston rod of the first cylinder 100, when the second adjusting block 520 is restricted from moving, the piston rod of the first cylinder 100 is also restricted from moving in the direction of the second cylinder 200, so that the stroke of the first cylinder 100 is restricted.

When the stroke of the first cylinder 100 needs to be adjusted again, the position of the first adjusting block 510 on the outer wall of the first cylinder 100 may be changed at this time, so that the relative distance between the first limiting portion 511 and the second limiting portion 521 is changed, and the moving stroke of the piston rod of the first cylinder 100 to the second cylinder 200 is changed again. In addition, since the movement of the piston of the first cylinder 100 can be restricted by the first stopper 511 during the extension movement, the first cylinder 100 can be prevented from continuously operating at the maximum stroke, and thus the service life of the first cylinder 100 can be extended as much as possible.

Further, in order to make the second position-limiting portion 521 better limited by the first position-limiting portion 511, in an embodiment, referring to fig. 1, the first position-limiting portion 511 includes a first side face 5111, the second position-limiting portion 521 includes a second side face 5211, wherein the second side face 5211 of the second position-limiting portion 521 is opposite to the first side face 5111 of the first position-limiting portion 511, in the moving process of the second adjusting block 520, the second side face 5211 abuts against the first side face 5111, and the first position-limiting portion 511 limits the second position-limiting portion 521 to move. That is, in the present embodiment, the movement of the second side surface 5211 of the second stopper 521 is restricted by the first side surface 5111 of the first stopper 511, thereby achieving the stroke adjustment of the first cylinder 100.

It is considered that, in adjusting the stroke of the first cylinder 100, it is implemented by changing the position of the first adjusting block 510 on the outer wall of the first cylinder 100, that is, when the position of the first adjusting block 510 on the first cylinder 100 is changed, the relative distance between the first limiting portion 511 and the second limiting portion 521 is changed, so that the stroke of the first cylinder 100 is changed. This solution has a disadvantage in that the first adjusting block 510 may interfere with the first clamping assembly 300 when changing the position of the first adjusting block 510, that is, the clamping function of the first clamping assembly 300 may be affected by the first adjusting block 510. To this end, in an embodiment, referring to fig. 2, the first adjusting assembly 500 further includes a first adjusting member 522, wherein the first adjusting member 522 is detachably disposed on the first position-limiting portion 511, and when the second position-limiting portion 521 moves, the first adjusting member 522 can abut against the second side surface 5211 of the second position-limiting portion 521. That is, in the present embodiment, it is not necessary to change the position of the first adjusting block 510 on the first cylinder 100, but only the position of the first adjusting member 522 on the first stopper portion 511 is changed, so that the relative distance between the first adjusting member 522 and the second side surface 5211 of the second stopper portion 521 is changed. The first adjusting member 522 interferes with the second side surface 5211 of the second limiting portion 521 to limit the movement of the piston rod of the first cylinder 100, so as to change the stroke of the first cylinder 100. When the stroke of the first cylinder 100 needs to be adjusted again, the position of the first adjusting member 522 in the first position-limiting portion 511 may be changed, for example, the relative distance between the first adjusting member 522 and the second side surface 5211 of the second position-limiting portion 521 is decreased or increased, so that the stroke of the first cylinder 100 is also changed.

Further, in an embodiment, the first position-limiting portion 511 is provided with a first threaded hole (not shown in the drawings) penetrating through the first position-limiting portion 511, the outer wall of the first adjusting member 522 is provided with a first thread 5221, the first adjusting assembly 500 further includes first nuts 523, the first thread 5221 of the first adjusting member 522 is connected with the first threaded hole in a matching manner, one end of the first adjusting member 522 can be abutted to the second side surface 5211 of the second position-limiting portion 521, the two first nuts 523 are respectively connected with the first thread 5221 of the first adjusting member 522 and abutted to two ends of the first threaded hole located in the first position-limiting portion 511, the two first nuts 523 limit the first adjusting member 522 to move relative to the first threaded hole, and the first adjusting member 522 can be a bolt or a screw rod, etc. When the stroke of the first cylinder 100 needs to be changed, the first adjusting member 522 may be rotated relative to the first threaded hole, so that the first adjusting member 522 is close to or away from the second side surface 5211 of the second limiting portion 521, and after the position of the first adjusting member 522 is adjusted, the first adjusting member 522 is fixed by the two first nuts 523, so that the first adjusting member 522 is prevented from moving relative to the first threaded hole.

In this embodiment, the second adjusting assembly 600 operates on the same principle as the first adjusting assembly 500, that is, the third limiting portion 611 limits the movement of the fourth limiting portion 621, so as to control the piston rod stroke of the second cylinder 200, and the structural connection manner of the second adjusting assembly 600 can refer to the first adjusting assembly 500.

Further, in an embodiment, referring to fig. 3, the third position-limiting portion 611 includes a third side surface 6111, wherein the fourth position-limiting portion 621 includes a fourth side surface 6211, and the fourth side surface 6211 of the fourth position-limiting portion 621 is opposite to the third side surface 6111 of the third position-limiting portion 611. In the moving process of the fourth adjusting block 620, the fourth side 6211 of the fourth position-limiting portion 621 abuts against the third side 6111 of the third position-limiting portion 611, and the third position-limiting portion 611 limits the fourth position-limiting portion 621 from moving.
