[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1-Figure 4 The utility model proposes a tightening inner clamping type knife remover, including a knife removing mechanism 1, the knife removing mechanism 1 includes a knife removing device outer shell 2 and a cylinder 3, the cylinder 3 is fixedly connected to the knife removing device outer shell 2, a clamping cavity is opened inside the knife removing device outer shell 2, a tapered hole 4 is opened on the inner wall of one side of the clamping cavity, four clamping members 5 are slidably installed in the clamping cavity, the four clamping members 5 are arranged in pairs in a central symmetry, and a tool monomer 6 is movably clamped in the tapered hole 4.

[0025] It should be noted that the clamping cavity includes a circular cavity part and an enlarged stepped part. This design is to cooperate with the special shape of the clamping piece for clamping operations. The combination of the circular cavity part and the stepped part can ensure that the clamping piece is firmly fixed in the clamping cavity, thereby improving the flexibility and applicability of clamping. This design adopts a simple structure, reduces manufacturing costs, and is easy to maintain and replace. It is also beneficial to improve the accuracy and stability of clamping, and is suitable for tool pickers in various automated processing equipment.

[0026] In this embodiment, a mounting plate 7 is provided at the bottom of the cylinder 3, and the mounting plate 7 is fixedly connected to the top of the outer shell 2 of the tool remover by a plurality of screws.

[0027] It should be noted that a threaded groove is provided on the top of the knife remover housing, which is compatible with the threaded hole on the mounting plate. The mounting plate and the knife remover housing are connected by multiple screws to ensure a firm connection between the knife remover and the mounting plate, thereby improving the stability of the entire knife remover system. The design of the threaded groove makes the connection between the mounting plate and the knife remover housing more convenient, and can be quickly installed and replaced, saving time and cost for maintenance and replacement.

[0028] In this embodiment, a connecting rod 8 is provided in the cylinder 3 , and a pull rod 9 is fixedly connected to one end of the connecting rod 8 .

[0029] It should be noted that the cylinder and the pull rod are usually connected by a connecting rod or a connecting rod. The connecting rod is a mechanical part that can connect the cylinder and the pull rod together through threaded connection or pin connection. In the pneumatic system, the cylinder transmits motion through the connecting rod and the pull rod. When the cylinder is controlled by air pressure, the cylinder piston will generate a push and pull force, and this force will be transmitted to the pull rod through the connecting rod, thereby realizing the movement of the pull rod.

[0030] In this embodiment, the clamping member 5 includes a prying head 10 and a clamping head 11 , and an annular groove is provided on the outer side of the pull rod 9 , and the prying heads 10 of the plurality of clamping members 5 are movably engaged in the annular groove.

[0031] In this embodiment, one side of the clamping member 5 is provided with an inclined surface, and the bottom end of the pull rod 9 is slidably connected with the inclined surfaces of the plurality of clamping members 5 .

[0032] It should be noted that, through the cooperation of the annular groove on the pull rod and the prying head of the clamping piece, the bottoms of the multiple clamping pieces are driven to shrink, and through the inclined surface of the pull rod connected with the inclined surface of the clamping piece, the bottoms of the multiple clamping pieces are driven to expand, thereby realizing the clamping and release function of the tool unit. Since the bottom of the clamping piece is shrunk or expanded by the pull rod, compared with some traditional clamping methods, this design has higher reliability and stability, and can ensure that the tool will not loosen or fall off during the processing process.

[0033] In this embodiment, the top of the tool body 6 is configured as a conical column, a pull head 12 is provided on the top of the tool body 6 , and the clamping head 11 of the clamping member 5 is movably in contact with the pull head 12 .

[0034] In this embodiment, the pull rod 9 is cylindrical, and a cavity 13 is provided inside the pull rod 9 .

[0035] It should be noted that the hollow design of the tie rod can reduce the weight of the tie rod, thereby reducing the overall weight of the cylinder system, reducing the load, and also reducing energy consumption. The hollow design of the tie rod can improve the rigidity of the tie rod, making it more stable when subjected to force. The hollow design can reduce weight and improve the performance of the cylinder system while maintaining sufficient strength and rigidity.

[0036] In this embodiment, the clamping member 5 is made of an elastic material, and the material of the clamping member 5 is set to be spring steel.

[0037] It should be noted that spring steel has excellent elastic properties and can quickly return to its original shape after being subjected to force, while having sufficient strength to withstand compression or tension. This material is very suitable for manufacturing clamps because they can provide the required elasticity to clamp objects and have sufficient strength to maintain the clamping force.

[0038] In this embodiment, the working principle of the equipment is: start the cylinder 3, and the cylinder 3 drives the connecting rod 8 and the pull rod 9 to move upward together. Since the clamping cavity is arranged in a step-like manner, the inclined surface contacts the step of the clamping cavity when the pull rod 9 is pulled upward, so that the clamping heads 11 of the multiple clamping members 5 are tightened, and the pulling head 12 on the top of the tool unit 6 is clamped. When the cylinder 3 drives the pull rod 9 to move downward, the bottom end of the pull rod 9 squeezes the inclined surfaces of the multiple clamping members 5, thereby driving the clamping heads 11 of the multiple clamping members 5 to move outward, thereby releasing the pulling head 12 on the top of the tool unit 6, thereby realizing the clamping and releasing functions of the tool unit 6.

[0039] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
