[0025] Please see Figure 1-4This embodiment discloses a welding rework auxiliary device, including a support platform 1 and a clamping mechanism. The clamping mechanism includes a base 2 rotatably mounted on the support platform 1 and two sets of clamping plate assemblies 3 facing each other on the base 2. Each clamping plate assembly 3 includes a clamping plate 301 rotatably mounted on the base 2 and lockable, and several clamping components 302 mounted on the clamping plate 301. Each clamping component 302 includes a fixing member 302a fixed on the clamping plate 301, an abutment member 302b slidably mounted on the fixing member 302a for abutting the workpiece, and an elastic element 302c disposed between the fixing member 302a and the abutment member 302b for providing force to the abutment member 302b. The structure of the support platform 1 is not limited, such as a table or a seat; the way the base 2 is driven to rotate on the support platform 1 is not limited, such as manual or motor-driven rotation; similarly, the way the clamping plate 301 is driven to slide on the base 2 is not limited, such as manual or electric sliding; through two opposing clamping plate assemblies 3, the two sets of clamping plate assemblies 3 can move relative to each other and clamp the workpiece to be repaired; a number of clamping components 302 are preferably arranged in an array on the clamping plate 301; since the abutting part 302b of the clamping component 302 can move, that is, the clamping component 302 is telescopic, for different shaped automotive parts, each clamping component 302 can be telescopically extended to clamp and fix most shaped automotive parts;

[0026] The welding rework auxiliary device in the above-mentioned structural design can adapt to the fixed installation of most irregular automotive parts, assisting in the welding rework of automotive parts and improving the efficiency of automotive parts welding rework. Specifically, by rotating the base 2 set on the support platform 1, the clamping mechanism can be easily rotated and repositioned, which is conducive to the operator to perform multi-angle rework operations on the parts, thus improving work efficiency. At the same time, since this clamping mechanism can meet the clamping of irregular parts through several clamping components 302, it is not necessary to change the clamping mechanism when clamping different automotive parts, reducing the time for changing the clamping mechanism and improving work efficiency. This device is particularly suitable for the welding rework of parts in the welding process of automotive body-in-white assembly, thereby improving the production efficiency of automotive parts welding rework and saving production costs. At the same time, since there are several clamping components 302, the stability of clamping can be guaranteed, thereby avoiding additional defects caused by workpiece loosening during welding rework and ensuring work quality.

[0027] In this embodiment, the fixing member 302a is a fixing cylinder, the abutting member 302b is slidably disposed within the fixing cylinder, and the elastic element 302c includes a first spring 302c1, a second spring 302c2, and a partition plate 302c3 disposed within the fixing cylinder. The partition plate 302c3 is movably disposed within the fixing cylinder. The two ends of the first spring 302c1 respectively abut against the bottom of the fixing cylinder and the partition plate 302c3, and the two ends of the second spring 302c2 respectively abut against the partition plate 302c3 and the abutting member 302b. Specifically, the abutting member 302b is an abutting rod, and two second springs 302c2 are designed. Of course, in other embodiments, the second spring 302c2 and the first spring 302c1 can also be designed as needed. Multiple fixed cylinders can be installed; the fixed cylinders can be fixed to the clamping plate 301 by welding, or mounting holes can be opened on the clamping plate 301, and then the fixed cylinders can be installed in the mounting holes with an interference fit. In this structural design, the elastic element 302c adopts two sets of springs set at both ends of the partition plate 302c3, namely the first spring 302c1 and the second spring 302c2 are connected in series through the partition plate 302c3. Under the premise that the abutment part 302b has the same sliding distance, the individual spring will not be compressed too much, and the clamping force will not be too large and damage the automotive parts. Similarly, the service life of the springs can also be guaranteed, which is conducive to extending the service life of the whole. At the same time, the clamping part 302 formed by this structure can be manufactured separately and then assembled with the clamping plate 301, which is conducive to the production assembly and subsequent maintenance of the device.

[0028] In this embodiment, a welding protection mechanism is also included. The welding protection mechanism includes a protective cover plate 4 for shielding the top of the two clamping plates 301. The protective cover plate 4 is rotatably mounted on the base 2. Specifically, the protective cover plate 4 is rotatably mounted on the base 2 and rotated by a drive motor. The protective cover plate 4 prevents debris from splashing from the top during welding repair work, avoids debris from falling randomly, helps maintain the cleanliness of the working environment, and reduces the risk of injury to workers. At the same time, since the protective cover plate 4 is rotatable, its angle can be adjusted. When clamping workpieces, the protective cover plate 4 can be rotated open to facilitate workpiece clamping; or the angle of the protective cover plate 4 can be adjusted during operation to avoid obstructing the operation.

[0029] In this embodiment, a rear shielding plate 201 is provided on the rear edge of the base 2, and the protective cover plate 4 is rotatably installed on the top of the rear shielding plate 201. Specifically, the rear shielding plate 201 and the base 2 are an integral structure. It can be understood that the "rear" here refers to the side away from the operator. By setting the rear shielding plate 201, the rear can be shielded, thereby preventing debris from flying out from the rear during the welding rework process, avoiding debris from falling to the ground, ensuring the cleanliness of the working environment, and facilitating debris collection and cleaning; further improving the overall protective effect.

[0030] In this embodiment, the protective cover plate 4 extends downward on both the left and right sides to form side baffles 401; the left and right directions refer to the left and right directions when the operator faces the support platform, that is, the attached... Figure 1 The left and right directions; specifically, here the side baffle 401 is a baffle plate with an integral structure with the protective cover plate 4, and the protective cover plate 4 has a U-shaped structure; by setting the side baffle 401, the protective effect can be further improved.

[0031] In this embodiment, a rotary motor 5 is provided in the middle of the support platform 1, and the output end of the rotary motor 5 is driven to the base 2. It can be understood that the output end of the rotary motor 5 generally refers to the output shaft of the rotary motor 5, and the output shaft of the rotary motor 5 can be driven to the base 2 through spline connection or other means. According to the load-bearing capacity requirements, a turntable bearing or the like can be provided between the base 2 and the support platform 1. The rotary motor 5 drives the base 2 to rotate, which is conducive to adjustment.

[0032] In this embodiment, the bottom of the base 2 is provided with a plurality of rollers 6, which are supported on the support platform 1. The plurality of rollers 6 are evenly distributed along the circumference. By providing a plurality of rollers 6, the support of the base 2 is enhanced and the structural reliability is improved.

The installation of the clamping plates 301 is completed through the guide rail assembly 7, which has a simple structure and good sliding reliability of the clamping plates 301; the drive motor 9 is a servo motor, and the arrangement position of the drive motor 9 is not limited. The workpiece can be directly connected to the bidirectional lead screw 8, or it can be connected to the bidirectional lead screw 8 via a gear transmission mechanism, etc., without limitation. It can be understood that the bidirectional lead screw 8 refers to a lead screw with opposite directions of rotation at both ends. The clamping plate 301 can be installed with the bidirectional lead screw 8 through a nut sleeve threadedly engaged. The bidirectional lead screw 8 is rotated by the drive motor 9, and the two sets of clamping plates 301 can come closer together to clamp the workpiece. This structure design has good transmission stability, good structure compactness, and convenient workpiece clamping. In use, simply place the workpiece between the two sets of clamping plates 301 and start the drive motor 9 to drive the two sets of clamping plates 301 to complete the workpiece clamping. Of course, it can be understood that the position of the clamping plate 301 can be locked by locking the rotation of the drive motor 9; or the clamping plate 301 can be locked by using a sliding lead screw nut mechanism with its reverse self-locking.
