[0002] Clamping devices are used to fix metal connectors in the machine tool to ensure dimensional accuracy. Common types of clamping devices include screw clamping, hydraulic clamping, and pneumatic clamping. Hydraulic clamping uses the pressure of hydraulic oil to drive a hydraulic cylinder, which causes the jaws to move and thus clamp the metal connector.

[0003] In existing metal connector processing, hydraulic clamping devices are used for fixing. However, if the metal part is irregular in shape or the clamping position is improper, uneven force will be applied to different parts of the chuck, accelerating local wear, reducing the service life of the chuck, and affecting the clamping accuracy. Therefore, this utility model proposes a metal connector processing fixing clamping device. Utility Model Content

[0020] 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.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a metal connector processing and fixing clamping device, including a hydraulic clamping device 2 installed on a machine tool 1. The hydraulic clamping device 2 consists of multiple jaws 21, a main body 22, and symmetrically arranged interfaces 23. Each jaw 21 is located at the top of the main body 22, and the symmetrically arranged interfaces 23 are located on the side of the main body 22. Each jaw 21 consists of a mounting head 211, a mounting base 212, and a mounting mechanism 213. The mounting head 211 is located at the end of the mounting base 212, and the mounting mechanism 213 is located between the mounting head 211 and the mounting base 212. The mounting mechanism 213 consists of a clamping block 2131, a clamping groove 2132, and symmetrically arranged... The device consists of an elastic component 2133, a slot 2132 located at the end of the mounting base 212, and a locking block 2131 fixed to the end of the mounting head 211. The locking block 2131 engages with the inner side of the slot 2132. The elastic component 2133 is located on both sides of the connection between the locking block 2131 and the slot 2132. The designed jaws 21 improve upon the previous method of fixing metal connectors via hydraulic clamping. During clamping, irregular shapes of the metal parts or improper clamping positions could cause uneven force distribution on the jaws, accelerating localized wear. By providing detachable jaws 21, when wear occurs in the clamping parts during long-term use, the worn areas can be individually replaced. To ensure the clamping effect of the metal connector through the hydraulic clamping device, the surface of the locking block 2131 is in contact with the inner wall of the locking groove 2132, and the end of the locking block 2131 has an inclined structure. The elastic component 2133 consists of a spring 2133A, a groove 2133B, a limiting groove 2133C, and a limiting block 2133D. The groove 2133B is opened on the side of the locking block 2131. Through the elastic component 2133, the locking block 2131 and the locking groove 2132 are fixed in position after being locked, thereby realizing the installation of the mounting head 211 and the mounting base 212. The limiting groove 2133C is opened on the side of the mounting base 212, and the limiting block 2133D is set at the limiting position. The inner side of groove 2133C and the inner side of recess 2133B are respectively fixed to the bottom end of limit block 2133D and the bottom end of recess 2133B. The top surface of limit block 2133D is in contact with the inner wall of limit groove 2133C. Fixing groove 2133C-1 is provided at the side edge of mounting base 212. Fixing groove 2133C-1 is in communication with limit groove 2133C. Without affecting the fixing effect of mounting head 211 and mounting base 212, the range of hand pressing on limit block 2133D is increased. A hydraulic cylinder is provided inside the main body 22.

[0022] In this embodiment, preferably, a sealing element 2132A is provided at the connection between the inner wall of the slot 2132 and the surface of the block 2131. The outer side of the sealing element 2132A is fixed to the inner wall of the slot 2132. When the block 2131 is inserted into the inner side of the slot 2132, the sealing element 2132A is squeezed simultaneously, thereby achieving a sealing effect on the installation between the mounting head 211 and the mounting base 212.

[0023] The working principle and usage process of this utility model are as follows: During the processing and fixing of the metal connector, the hydraulic system is started through the external pipeline. The hydraulic pump pressurizes the hydraulic oil, which then enters the hydraulic cylinder through the pipeline and interface 23. Under the action of the oil pressure, the piston moves linearly within the hydraulic cylinder. This piston movement is transmitted to the chuck 21 through a specific mechanical structure, causing the chuck 21 to move radially inward, thereby clamping the metal connector and fixing it in place. When the processing is complete and loosening is required, the hydraulic system reverses, and the hydraulic oil returns to its original position. When the piston moves in the opposite direction, the pawl 21 moves radially outward, releasing the metal part. When it is necessary to disassemble the worn part at the end of the pawl 21, the limiting blocks 2133D on both sides of the connection between the mounting head 211 and the mounting base 212 are pressed, so that the limiting blocks 2133D are separated from the limiting groove 2133C and embedded in the inner side of the groove 2133B, and the spring 2133A is compressed. Then the mounting head 211 is pulled, so that the pawl 2131 is separated from the pawl groove 2132, thus completing the disassembly of the worn mounting head 211.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
