Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, the present embodiment provides a clamping apparatus 100, wherein the clamping apparatus 100 includes a clamping assembly 10 and a driving assembly 20 for simultaneously clamping a plurality of workpieces 40 on a pallet 30 for transfer.

Referring to fig. 2 and 3, the clamping assembly 10 includes a cylinder 11, a plurality of guides 12, and a plurality of clamping members 13 corresponding to the plurality of guides 12. In the present embodiment, the number of the guide members 12 and the holding members 13 is two, so that the holding device 100 holds or releases two workpieces 40 at the same time. The cylinder 11 is substantially cylindrical, and the cylinder 11 is hollow and has a receiving cavity (not shown) for connecting to the driving assembly 20 to hold the workpiece 40. One end of the cylinder 11 is connected to two guide members 12, the guide members 12 are used for guiding the driving assembly 20, and the other ends of the two guide members 12 are respectively connected to corresponding clamping members 13.

The plurality of workpieces 40 are placed on the tray 30, and the distance between the adjacent workpieces 40 is equal to the distance between the two clamping pieces 13, so that the two clamping pieces 13 accurately clamp the two workpieces 40, and the clamping accuracy of the clamping device 100 is improved.

The driving assembly 20 includes a pressing head 24, a push rod 21, a top plate 22, and a plurality of sleeves 23 corresponding to the clamping members 13 one by one. The push rod 21 is partially slidably disposed in the accommodating cavity of the cylinder 11, one end of the push rod 21 is fixedly connected to the top plate 22, the other end of the push rod 21 away from the top plate 22 is fixedly connected to the press head 24, and the press head 24 is pressed to drive the top plate 22 to move toward the workpiece 40 through the push rod 21. One side of the top plate 22, which is far away from the pressure head 24, is fixedly connected with two sleeves 23, and the two sleeves 23 both have a hollow structure, and the two sleeves 23 are respectively sleeved outside the corresponding clamping members 13 in a sliding manner. The top plate 22 is provided with a plurality of limiting holes 222 corresponding to the guide members 12 one by one, and the guide members 12 are movably inserted into the corresponding limiting holes 222, so that the guide members 12 guide the top plate 22, and the sleeve 23 slides relative to the clamping member 13, so that the clamping member 13 accurately clamps or releases the workpiece 40.

The driving assembly 20 further includes a positioning element 25, the top plate 22 has a first positioning hole 221, the sleeve 23 has a second positioning hole 231 corresponding to the first positioning hole 221, and the positioning element 25 is disposed through the first positioning hole 221 and the second positioning hole 231 to connect the top plate 22 and the sleeve 23, so as to fix the top plate 22 and the sleeve 23.

Specifically, when the ram 24 is pressed to move the ejector rod 21 toward the workpiece 40, so that the ejector rod 21 pushes the top plate 22 to move, the sleeve 23 slides relative to the clamping member 13, so that the clamping member 13 moves into the sleeve 23 and the two clamping members 13 simultaneously clamp the two workpieces 40. When the press head 24 is released to enable the ejector rod 21 to move away from the workpiece 40, the ejector rod 21 drives the top plate 22 to move, the sleeve 23 slides relative to the clamping piece 13, the clamping piece 13 extends out of the sleeve 23, and therefore the two clamping pieces 13 release the two workpieces 40 at the same time.

Both the clamping members 13 include a clamping portion 131 and a connecting portion 132. The clamping portion 131 is disposed at a position away from the top plate 21 for clamping the workpiece 40, and the connecting portion 132 is disposed between the guide 12 and the clamping portion 13 and connected to the guide 12 and the clamping portion 131, respectively.

Specifically, the two clamping members 13 further include fixing portions 133, the clamping portion 131 is provided with a first fixing hole 134, a second fixing hole 135 is provided at a position opposite to the first fixing hole 134 of the connecting portion 132, and the fixing portions 133 are disposed through the first fixing hole 134 and the second fixing hole 135 to connect the clamping portion 131 and the connecting portion 132, so as to fix the clamping portion 131 and the connecting portion 132. In one embodiment, the fixing portion is a pin.

Each clamping portion 131 comprises a plurality of clamping jaws 136, the plurality of clamping jaws 136 are arranged at positions, away from the connecting portion 132, of the clamping portion 131 at intervals, the ejector rod 21 drives the fixed plate 22 to move towards or away from the workpiece 40, so that the sleeve 23 moves relative to the clamping jaws 136, and the plurality of clamping jaws 136 move into the sleeve 23 or extend out of the sleeve 23 to clamp the workpiece 40 or loosen the workpiece 40.

The clamping member 13 further includes an elastic portion 137, the elastic portion 137 is sleeved on the connecting portion 132, one end of the elastic portion 137 abuts against the clamping portion 131, the other end of the elastic portion 137 abuts against the sleeve 23, when the workpiece 40 is clamped, the sleeve 23 slides relative to the clamping portion 131, the elastic portion 137 is compressed to enable the clamping portion 131 to clamp the workpiece, and when the workpiece 40 is released, the elastic portion 137 provides elastic force to enable the sleeve 23 to reset, so that the workpiece 40 is clamped again, and the working efficiency of the clamping device 100 is further improved. In the present embodiment, the elastic portion 137 is a spring.

The working process of the embodiment of the application is as follows: the clamping device 100 of the present application is moved over the tray 30 so that the clamp 13 corresponds to the workpiece 40. The plurality of jaws 136 of the clamping portion 131 are initially moved away from each other, the clamping device 100 is moved downward to allow the workpiece 40 to enter the middle of the plurality of jaws 136, the press head 24 is then pressed to move the fixed plate 22 toward the workpiece 40 through the push rod 21, so that the sleeve 23 moves relative to the jaws 136 and compresses the elastic portion 137, and the plurality of jaws 136 enter the sleeve 23, at this time, the plurality of jaws 136 approach each other under the constraint of the sleeve 23 to clamp the plurality of workpieces 40, and then the clamping device 100 clamps the workpiece 40 to a designated position. When the workpiece 40 needs to be loosened, the pressure head 24 is loosened, the elastic part 137 pushes the sleeve 23 to reset, the sleeve 23 is no longer restrained on the plurality of clamping jaws 136, and the plurality of clamping jaws 136 are far away from each other under the action of the elastic force of the clamping jaws 136, so that the plurality of workpieces 40 are loosened.

The clamping device 100 drives the top plate 22 to move through the ejector rod 21, so as to move the sleeve 23 relative to the clamping members 13, and thus the clamping members 13 move into the corresponding sleeves 23 respectively to simultaneously clamp the workpiece 40. Compared with the prior art, the method is simple to operate, the workpieces 40 are prevented from being installed partially or neglected, the workpieces 40 are placed in place at one time, and the working efficiency is improved.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
