Description

Technical Field

[0001] This utility model relates to the field of roller processing technology, specifically a fixing fixture for roller processing. Background Technology

[0002] As an important component at the bottom of the refrigerator, the refrigerator rollers play a vital role in facilitating movement, shock absorption, anti-slip, moisture prevention, and protecting the refrigerator and the ground. Users can easily move the refrigerator to the desired position by simply pushing it gently, without having to drag it. During the production and processing of refrigerator drawer rollers, a series of assembly processes are required to position and fix the rollers on the processing equipment.

[0003] However, existing roller fixing fixtures can only position and fix rollers of a certain size, making it difficult to fix and clamp rollers of different diameters. The positioning and fixing effect is poor, the application range is small, and there are certain limitations. Furthermore, during the processing of the positioned and fixed rollers, the processing equipment needs to exert a certain amount of pressure on the rollers, which can easily affect the stability of the rollers, causing them to loosen or shift, thereby affecting the processing accuracy of the rollers and increasing the defect rate of the finished rollers. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing fixture for roller processing. Through the structural design of the fixing seat, elastic clamping component, positioning slot and ring magnet, rollers of different diameters can be fixedly clamped, which can avoid loosening or displacement during the roller processing and solve the problems of difficulty in fixing and clamping rollers of different diameters and loosening or displacement during roller processing.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a fixing fixture for roller processing, comprising a fixture body and a turntable. The fixture body has six fixtures, each including a fixed base and an elastic clamping member. The fixed base has six receiving slots. The elastic clamping member is disposed in the receiving slot and includes a spring and an arc-shaped clamping plate. One end of the spring is provided with a movable head that cooperates with the receiving slot. The arc-shaped clamping plate is vertically mounted on the movable head and has a positioning slot. An arc-shaped guide plate is provided at the top of the arc-shaped clamping plate. A support ring is provided at the top center of the fixed base, and a ring magnet is embedded in the support ring.

[0007] Furthermore, a damping pad is provided at the end of the spring away from the moving head, and one side of the damping pad is connected to the inner wall surface of the receiving groove.

[0008] Furthermore, a sliding block is provided on the movable head, and the sliding block cooperates with the receiving groove.

[0009] Furthermore, the top of the sliding block passes through the receiving groove, and the top surface of the sliding block is connected to the bottom end of the arc-shaped clamp.

[0010] Furthermore, an arc-shaped groove is formed on the top surface of the support ring, and the annular magnet cooperates with the arc-shaped groove.

[0011] Furthermore, all six clamp bodies are mounted on the top surface of the turntable.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of the fixed base and elastic clamping components, uses the bottom of the roller to compress the six elastic clamping components, allowing the roller to be clamped between the arc-shaped clamping plates on the six elastic clamping components. The rebound force generated by the spring compression achieves stable clamping and fixing of the roller by the six arc-shaped clamping plates. This allows for convenient fixing and clamping of rollers of different diameters, increases the application range of the fixture, effectively improves the positioning and fixing effect of the roller, and enhances the applicability of the fixture.

[0014] 2. This utility model, through the structural design of positioning slots and ring magnets, allows the outer surface of the roller rim to be fitted with six positioning slots, and the bottom surface of the roller to be attracted by the ring magnets. This effectively improves the overall stability of the roller during processing, avoids the squeezing force generated by the processing equipment during the processing of the roller, which could cause the roller to loosen or shift, ensures the processing accuracy of the roller, and greatly reduces the defect rate of the finished roller.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a fixed fixture for roller processing, including a fixture body 1 and a turntable 6. Six fixture bodies 1 are installed on the top surface of the turntable 6 to ensure the processing of the roller. There are six fixture bodies 1. Each fixture body 1 includes a fixed seat 2 and an elastic clamping member 3. The fixed seat 2 is provided with a receiving groove 201. There are six receiving grooves 201. The elastic clamping member 3 is disposed in the receiving groove 201.

[0024] The elastic clamping component 3 includes a spring 301 and an arc-shaped clamping plate 303. One end of the spring 301 is provided with a movable head 302, which cooperates with the receiving groove 201. The end of the spring 301 away from the movable head 302 is provided with a damping pad 3011. One side of the damping pad 3011 is connected to the inner wall surface of the receiving groove 201, which can ensure that the spring 301 can stably contract and rebound within the receiving groove 201. The arc-shaped clamping plate 303 is vertically mounted on the movable head 302. The movable head 302 is provided with a sliding block 304, which cooperates with the receiving groove 201. The top of the sliding block 304 passes through the receiving groove 201, and the top surface of the sliding block 304 is connected to the bottom end of the arc-shaped clamping plate 303, which can ensure the movement stability of the arc-shaped clamping plate 303. The arc-shaped clamping plate 303 is provided with a positioning slot 3031, and the top of the arc-shaped clamping plate 303 is provided with an arc-shaped guide plate 3032.

[0025] When processing the roller, the roller is placed directly above the fixed base 2, and then the roller is moved vertically downwards until the bottom of the roller contacts the surface of the arc-shaped guide plate 3032 on the six elastic clamping members 3. Then the roller is pressed down, causing the bottom of the roller to squeeze the six elastic clamping members 3. The squeezing force is transmitted to the arc-shaped clamping plate 303 through the arc-shaped guide plate 3032, so that the arc-shaped clamping plate 303 is subjected to a force towards the outside of the fixed base 2, causing the sliding block 304 to slide in the receiving groove 201. The movement of the sliding block 304 pushes the movable head 302 to slide in the receiving groove 201, so that the movable head 302 squeezes the spring 301. After being squeezed, the spring 301 retracts in the receiving groove 201. The contraction causes the arc-shaped clamping plate 303 to move horizontally outward toward the fixed base 2, thereby causing all six arc-shaped clamping plates 303 on the elastic clamping members 3 to move horizontally outward toward the fixed base 2. Through the movement of the six arc-shaped clamping plates 303, the six arc-shaped clamping plates 303 expand outward simultaneously, increasing the circular space they enclose. This allows the roller to be inserted between the six arc-shaped clamping plates 303 on the elastic clamping members 3. The rebound force generated by the compression of the spring 301 achieves stable clamping and fixing of the roller by the six arc-shaped clamping plates 303. This enables convenient fixing and clamping of rollers of different diameters, increases the application range of the fixture, effectively improves the positioning and fixing effect of the roller, and enhances the applicability of the fixture.

[0026] A support ring 4 is provided at the top center of the fixed base 2. A ring magnet 5 is embedded in the support ring 4. An arc groove 401 is provided on the top surface of the support ring 4. The ring magnet 5 cooperates with the arc groove 401, which can facilitate the installation of the ring magnet 5.

[0027] During the process of the roller being inserted between the six arc-shaped clamping plates 303, the roller is pressed until the outer surface of the roller rim is respectively inserted into the positioning slots 3031 on the six arc-shaped clamping plates 303. After the outer surface of the roller rim is inserted into the six positioning slots 3031, the bottom surface of the roller contacts the surface of the support ring 4 at the center of the fixed seat 2. Since the roller axle and hub are both made of steel, the roller is attracted by the ring magnet 5 embedded in the support ring 4, so that the roller can be stably restricted between the six elastic clamping parts 3 on the fixed seat 2. This can effectively improve the overall stability of the roller during processing, avoid the squeezing force generated by the processing equipment during the processing of the roller, and prevent the roller from becoming loose or shifting. This ensures the processing accuracy of the roller and greatly reduces the defect rate of the finished roller.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
