Description

Technical Field

[0001] This utility model relates to the field of mold metal parts technology, specifically a clamping device for processing mold metal parts. Background Technology

[0002] Mold metal parts are core components in mold manufacturing. They are usually made of high-strength, high-wear-resistant alloy materials and manufactured through processes such as forging, precision machining, and heat treatment. They possess high precision, high hardness, and good fatigue resistance, and are widely used in the molding and processing of products such as automotive body panels, electronic connectors, and home appliance housings. Their quality directly affects the mold life and finished product precision, making them a key basic component for achieving efficient and stable mass production in modern manufacturing.

[0003] According to the polyhedral part fixture with publication number CN206561302U published on the Chinese Patent Network, the polyhedral part fixture has a rotary shape and a cavity that matches the outline of the polyhedral part. The fixture is mounted on a lathe chuck using fasteners and engages with the jaws on the chuck to clamp the polyhedral part. This utility model provides a polyhedral part fixture that can be used with hydraulic or pneumatic chucks. By using the soft jaws of the chuck to clamp the part, it enables rapid clamping of polyhedral parts while accurately ensuring the dimensional tolerances between the lathe's rotation center and the part's outer surface. This solution has a simple structure, high positioning accuracy, low manufacturing cost, and is convenient for switching between different products. However, the clamping device is relatively cumbersome to assemble and disassemble. When clamping parts, it is difficult to easily remove and replace easily damaged jaws, requiring a long period of use for replacement, causing unnecessary trouble for the user.

[0004] Therefore, the fixture needs to be redesigned and modified to effectively prevent it from being difficult to disassemble and assemble. Utility Model Content

A spring plate 207 is fixedly connected to the outer side of the movable plate 205. A baffle 208 is fixedly connected to the outer side of the spring plate 207. The inner side of the baffle 208 is fixedly connected to the outer side of the trapezoidal blocks 204.

[0028] refer to Figure 2 The rotating assembly 3 includes a toothed ring 301, the top of which is fixedly connected to the bottom of the clamping seat 1. A fixing plate 302 is provided at the bottom of the clamping seat 1. A toothed block 303 is engaged on the surface of the toothed ring 301. A screw 304 is fixedly connected to the front side of the toothed block 303. A rotating sleeve 305 is threadedly connected to the surface of the screw 304. The rotating sleeve 305 is located inside the fixing plate 302.

[0029] As a technical optimization of this utility model, by setting the rotating component 3, the angle of the clamping seat 1 can be adjusted, thereby improving the ease of adjustment of the clamping seat 1.

[0030] refer to Figure 2 A rotating block 4 is fixedly connected to the surface of the rotating sleeve 305, and the surface of the rotating block 4 is provided with anti-slip texture.

[0031] As a technical optimization of this utility model, by setting the rotating block 4, the user can easily rotate the rotating sleeve 305, thus improving the ease of rotation of the rotating sleeve 305.

[0032] refer to Figure 3 A pull plate 5 is fixedly connected to the inner side of the movable plate 205, and the surface of the pull plate 5 is provided with anti-slip texture.

[0033] As a technical optimization of this utility model, by setting the pull plate 5, it is easier for the user to pull the movable plate 205, thus improving the ease of pulling the movable plate 205.

[0034] refer to Figure 2 The top of the fixing plate 302 is provided with an arc-shaped groove 6, and the bottom of the clamping seat 1 is fixedly connected with a round rod 7, which is movably connected to the arc-shaped groove 6.

[0035] As a technical optimization of this utility model, by setting the arc groove 6 and the round rod 7, the clamping seat 1 can be guided and limited, thereby improving the rotational stability of the clamping seat 1.

[0036] refer to Figure 3 Support bars 8 are fixedly connected to the outer side of the movable plate 205. The number of support bars 8 is several and they are evenly distributed.

[0037] As a technical optimization of this utility model, by setting the support bar 8, the movable plate 205 can be strengthened, thereby improving the overall strength of the movable plate 205.

[0038] The working principle and usage process of this utility model are as follows: When it is necessary to easily replace the clamping claw 201, the following steps can be followed: First, pull the pulling plate 5 smoothly outward. The pulling plate 5 drives the connected moving plate 205 to move outward synchronously. The moving plate 205 further drives the limiting frame 206 to move outward until the limiting frame 206 is completely separated from the top plate 203. Then, pull the top plate 203 upward. The top plate 203 drives the positioning rod 202 to move upward together, so that the positioning rod 202 is pulled out from the corresponding slot of the clamping claw 201. At this time, the clamping claw 201 is in a detachable state and can be easily removed. If it is necessary to reinstall the clamping claw 201, simply follow the reverse order of the above steps to complete the installation quickly and stably, improving efficiency. The ease and efficiency of assembling and disassembling the clamping claw 201 are evident when the angle of the clamping seat 1 needs to be flexibly adjusted. Rotating the rotating block 4 causes the rotating sleeve 305 to rotate synchronously. The rotating sleeve 305, through its inner threaded structure, drives the mating screw 304 forward. As the screw 304 moves forward, it also drives the toothed block 303 forward until the toothed block 303 and the toothed ring 301 are completely separated. At this point, the clamping seat 1 loses its angle locking limitation, and the operator can freely rotate the clamping seat 1 to the desired angle according to actual needs. After adjustment, the toothed block 303 and the toothed ring 301 can be re-engaged through reverse operation, thus achieving the adjustment and fixation of the clamping seat 1's angle and meeting the angle adjustment needs in diverse usage scenarios.

[0039] In summary, this clamping device for machining metal parts based on molds utilizes a disassembly and assembly component to disassemble and replace the clamping jaws. When clamping parts, easily damaged jaws can be easily disassembled and replaced without requiring a long period of use, thus avoiding unnecessary trouble for the user and solving the problem of difficult disassembly and assembly.
