The setting of the moving member 203 can drive the two groups of clamping members to move, and the workpiece can be clamped at different positions according to the width of the workpiece.

[0032] Example 2

[0033] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, the first clamping member 201 includes a first clamping block 201a and a first clamping rod 201b. The first clamping block 201a is disposed at one side of the workbench 102, and the first clamping rod 201b is fixed to one side of the first clamping block 201a.

[0035] When one side of the workpiece needs to be clamped, the first clamping block 201a is moved to contact one side of the workpiece so as to clamp the one side of the workpiece. The first clamping rod 201b can be used to drive the first clamping block 201a to move.

[0036] Specifically, the first clamping member 201 further includes a moving frame 201c, a hinge block 201d and a positioning plate 201e. The moving frame 201c is fixed to one side of the first clamping rod 201b, the hinge block 201d is fixed to the bottom of the moving frame 201c, and the positioning plate 201e is hinged to the hinge block 201d.

[0037] The movement of the moving frame 201c can drive the first clamping rod 201b to move, and when the moving frame 201c moves, the hinge block 201d can be driven to move. At this time, the moving frame 201c can be supported to prevent the moving frame 201c from shifting. The positioning plate 201e can be set to support the hinge block 201d to prevent the hinge block 201d from shifting.

[0038] Specifically, the second clamping member 202 includes a moving sleeve 202a, a positioning rod 202b and a first spring 202c. The moving sleeve 202a is arranged on the top of the moving frame 201c, the positioning rod 202b is inserted into the top of the moving sleeve 202a, the positioning rod 202b and the moving sleeve 202a are movably connected, and the first spring 202c is sleeved on the outside of the positioning rod 202b.

[0039] The positioning rod 202b is fixed to the top of the moving frame 201c, and a baffle is arranged on the top of the positioning rod 202b. One end of the first spring 202c is fixed to the top of the moving sleeve 202a, and the other end is fixed to the bottom of the baffle. When the moving sleeve 202a moves, the positioning rod 202b can be driven to move. At this time, the movement of the positioning rod 202b will drive the moving frame 201c to move, and when the moving sleeve 202a moves, it can slide on the positioning rod 202b. At this time, an extrusion force can be applied to the first spring 202c. When the moving sleeve 202a needs to be returned to its original position, the moving sleeve 202a can be driven to return to its original position through the rebound force of the first spring 202c.

[0040] Specifically, the second clamping member 202 further includes a second clamping block 202d and a second clamping rod 202e. The second clamping rod 202e is hinged to the top of the positioning rod 202b, and the second clamping block 202d is fixed to the bottom of the second clamping rod 202e.

[0041] When the movable sleeve 202a moves on the positioning rod 202b, it will drive the second clamping rod 202e to move. The movement of the second clamping rod 202e drives the second clamping block 202d to move. By moving the second clamping block 202d to contact the top of the workpiece, the top of the workpiece can be clamped.

[0042] Specifically, the second clamping member 202 further includes a connecting block 202f and a first hinged rod 202g, wherein the connecting block 202f is fixed to one end of the second clamping rod 202e, and one end of the first hinged rod 202g is hinged to the connecting block 202f, and the other end is hinged to one side of the movable sleeve 202a.

[0043] When the movable sleeve 202a moves on the positioning rod 202b, it will drive the first hinged rod 202g to move. At this time, the first hinged rod 202g will squeeze one end of the connecting block 202f. The squeezing of one end of the connecting block 202f can drive the second clamping rod 202e to move, so that the second clamping rod 202e is tilted. At this time, the second clamping rod 202e will drive the second clamping block 202d to move to contact the top of the workpiece. When the first hinged rod 202g moves, the first hinged rod 202g will tilt, and the tilted first hinged rod 202g can squeeze one end of the connecting block 202f.

[0044] Specifically, the second clamping member 202 further includes a second hinged rod 202h and a cylinder 202i. The second hinged rod 202h is hinged to one side of the movable sleeve 202a, and the cylinder 202i is fixed to one end of the second hinged rod 202h.

[0045] The second hinged rod 202h is arranged on one side of the first hinged rod 202g, and the second hinged rod 202h and the first hinged rod 202g are movably connected. Through the movement of the second hinged rod 202h, the movable sleeve 202a can be pushed first to make the movable sleeve 202a tilted. The movement of the movable sleeve 202a drives the first clamping block 201a to contact one side of the workpiece, and then the movable sleeve 202a is continued to be pushed to make the movable sleeve 202a slide on the positioning rod 202b. The cylinder 202i is hinged to the top of the positioning plate 201e. The second hinged rod 202h can be driven to move through the setting of the cylinder 202i.

[0046] Example 3

[0047] Reference Figure 2 and Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0048] Specifically, the movable member 203 includes a movable frame 203a and a slide plate 203b. The movable frame 203a is fixed to the bottom of the positioning plate 201e, and the slide plate 203b is plugged into one side of the movable frame 203a. The slide plate 203b and the movable frame 203a are movably connected.

[0049] When it is necessary to clamp the workpiece at different positions, the movable frame 203a is moved. The movement of the movable frame 203a can drive the positioning plate 201e to move. The movement of the positioning plate 201e can drive the first clamping block 201a and the second clamping block 202d to move, so that the workpiece can be clamped at different positions. The slide plate 203b is fixed on the top of the workbench 102. The movable frame 203a can be supported by the setting of the slide plate 203b to prevent the movable frame 203a from shifting.

[0050] Specifically, the moving member 203 further includes a limit block 203c and a push plate 203d. The limit block 203c slides inside the slide plate 203b, and the push plate 203d is fixed to one side of the limit block 203c.

[0051] The push plate 203d is plugged into one side of the movable frame 203a, and the push plate 203d is movably connected to the movable frame 203a. A limiting groove corresponding to the limiting block 203c is provided in the slide plate 203b. After the movable frame 203a is moved to the specified position, the movable frame 203a can be limited by engaging the limiting block 203c with the limiting groove. When it is necessary to release the limit on the movable frame 203a, the push plate 203d is pushed, and the push plate 203d drives the limiting block 203c to separate from the limiting groove, thereby releasing the limit on the movable frame 203a.

[0052] Specifically, the moving member 203 further includes a second spring 203e and a fixed plate 203f. The second spring 203e is fixed to one side of the push plate 203d, and the fixed plate 203f is fixed to one end of the second spring 203e.

[0053] The fixed plate 203f is fixed to the inner wall of the movable frame 203a, and can apply a squeezing force to the second spring 203e when pushing the push plate 203d. The push plate 203d moves to drive the limit block 203c to separate from the limit groove, thereby releasing the limit on the movable frame 203a. After moving the movable frame 203a to the specified position, the push plate 203d is released. At this time, the rebound force of the second spring 203e will drive the push plate 203d to return to its original position, so that the limit block 203c is engaged with the limit groove, thereby limiting the movable frame 203a again.

[0054] When in use, when it is necessary to process a workpiece, the workpiece is first placed on the workbench 102, and then the positions of the first clamping block 201a and the second clamping block 202d are moved according to the size of the workpiece, and the limit of the movable frame 203a is first released, and the push plate 203d is pushed. When the push plate 203d moves, a squeezing force is applied to the second spring 203e, and the push plate 203d moves to drive the push plate 203d to drive the limit block 203c to separate from the limit groove, thereby releasing the limit of the movable frame 203a, and then the movable frame 203a is moved. 203a moves, and the movement of the movable frame 203a will drive the positioning plate 201e to move. The movement of the positioning plate 201e can drive the first clamping block 201a and the second clamping block 202d to move. After the first clamping block 201a and the second clamping block 202d are moved to the specified positions, the push plate 203d is released. At this time, the rebound force of the second spring 203e will drive the push plate 203d to return to its original position, so that the limit block 203c is engaged with the limit groove, so that the movable frame 203a can be limited again to prevent the movable frame 203a from deviating.

[0055] Then start the cylinder 202i, which will drive the second hinged rod 202h to move. Through the movement of the second hinged rod 202h, the movable sleeve 202a can be pushed first to tilt the movable sleeve 202a. The tilt of the movable sleeve 202a will drive the positioning rod 202b to tilt, and the positioning rod 202b will drive the movable frame 201c to move. The movement of the movable frame 201c can drive the first clamping rod 201b to move. The movement of the first clamping rod 201b will drive the first clamping block 201a to move. By moving the first clamping block 201a to contact one side of the workpiece, one side of the workpiece can be clamped.

[0056] After the first clamping block 201a is moved to contact one side of the workpiece, the cylinder 202i will continue to push the movable sleeve 202a to make the movable sleeve 202a slide on the positioning rod 202b. When the movable sleeve 202a slides on the positioning rod 202b, it can apply an extrusion force to the first spring 202c. When the movable sleeve 202a moves on the positioning rod 202b, it will drive the first hinge rod 202g to move. When the first hinge rod 202g moves, the first hinge rod 202g will tilt. Through the tilted first hinge rod 202g, one end of the connecting block 202f can be squeezed. The squeezing of one end of the connecting block 202f can drive the second clamping rod 202e to move and tilt the second clamping rod 202e. At this time, the second clamping rod 202e will drive the second clamping block 202d to move to contact the top of the workpiece, so that the top of the workpiece can be clamped, and the stability of the workpiece can be guaranteed when the workpiece is processed.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
