Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, specifically to a four-axis high-precision pneumatic clamping fixture tooling. Background Technology

[0002] Common clamping devices typically employ a double-clamp structure, consisting of two clamping bodies. These clamps are driven by a linkage or gear meshing mechanism. This type of device, which uses a mechanical structure to drive the jaws, has relatively weak gripping force and the clamping force is not adjustable. It has a limited range of applications and cannot perform precise clamping. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing clamping fixtures generally use mechanical clamping structures for clamping, and the clamping force is generally not adjustable, making it impossible to perform precise clamping.

[0005] As a further embodiment of this utility model: a motor is fixed above one end of the connecting plate, and the output end of the motor passes through the connecting plate and is fixed to the upper side of the connecting plate. The motor can drive the connecting plate to rotate.

[0006] As a further embodiment of this utility model: a top plate is fixed at the top of the limiting frame, a telescopic rod is fixed at the lower side of the top plate, and blocks are fixed on both sides of the connecting plate three on both sides of the limiting frame. The bottom end of the telescopic rod is fixed to the upper side of the connecting plate three, and the telescopic rod can drive the connecting plate three to move.

[0007] As a further embodiment of this utility model: a second motor is fixed on the upper side of the connecting plate three, and the output end of the second motor passes through the connecting plate three and is fixed to the upper side of the rotating plate. The second motor can drive the rotating plate to rotate.

[0008] As a further embodiment of this utility model: there are three pairs of limiting plates and three connecting rods.

[0009] As a further embodiment of this utility model: the air pump is connected to an external cylinder, and the telescopic rod, motor one, and motor two are electrically connected to an external power source.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This patent adds a clamping structure, which uses an air pump as the power source for clamping.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0020] Combined with appendix Figure 1 , 3 4. It can be seen that the installation includes a mounting plate 1, a connecting plate 1 2 fixed on one side of the mounting plate 1, a connecting plate 2 3 below the connecting plate 1 2, a limit frame 4 fixed at the end of the connecting plate 1 2, a connecting plate 3 5 slidably arranged in the limit frame 4, and a clamping structure below the connecting plate 3 5. The clamping structure includes an air pump 6. By starting the air pump 6, the hinge seat can be moved up and down, thereby moving the claw 9. Three hinge seats are fixed at the top of the air pump 6. Several pairs of limit plates 7 are evenly fixed at the bottom of the outer side of the air pump 6. A limit block 8 is fixed between each pair of limit plates 7, which can limit the sliding direction of the claw 9. The claw 9 is slidably arranged between each pair of limit plates 7 on the outer side of the limit block 8. The top of the claw 9 is hinged to the hinge seat. Several connecting rods 10 are fixed on the upper side of the air pump 6. A rotating plate 11 is fixed at the top of the connecting rod 10. There are three pairs of limit plates 7 and three connecting rods 10.

[0021] Combined with appendix Figure 2 It can be seen that a motor 12 is fixed above the upper end of the connecting plate 12. The output end of the motor 12 passes through the connecting plate 12 and is fixed to the upper side of the connecting plate 23. The motor 12 can drive the connecting plate 23 to rotate. A top plate 13 is fixed at the top of the limiting frame 4. A telescopic rod 14 is fixed at the lower side of the top plate 13. Blocks 15 are fixed on both sides of the connecting plate 35 on both sides of the limiting frame 4. The bottom end of the telescopic rod 14 is fixed to the upper side of the connecting plate 35. The telescopic rod 14 can drive the connecting plate 35 to move. A motor 2 16 is fixed on the upper side of the connecting plate 35. The output end of the motor 2 16 passes through the connecting plate 35 and is fixed to the upper side of the rotating plate 11. The motor 2 16 can drive the rotating plate 11 to rotate. The air pump 6 is connected to the external cylinder. The telescopic rod 14, motor 12, and motor 2 16 are electrically connected to the external power supply.

[0022] The working principle of this application is as follows: When clamping, the air pump 6 is started, which can drive the hinge seat to move up and down, thereby driving the jaw 9 to move up and down. When the jaw 9 moves, the movement direction of the jaw 9 will be affected by the limitation of the limit block 8, thus realizing clamping.

[0023] By starting motor 12, connecting plate 3 can be rotated, telescopic rod 14 can move connecting plate 5 up and down, and motor 16 can rotate rotating plate 11, so as to rotate the clamping structure.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
