Description

Technical Field

[0001] The present invention relates to the technical field of stamping part repair equipment, and in particular to a fixing mechanism for stamping part repair. Background Art

[0002] In the light commercial vehicle market, "carrying more and running faster" is one of the core demands of customers, especially in the field of logistics and transportation. Customers hope that light commercial vehicles can provide a larger cargo box space so that more goods can be loaded at one time, thereby improving transportation efficiency. In automobile design, in order to increase the internal cavity size of the vehicle model, it is often necessary to optimize the body structure, but this may sacrifice the fullness of the side panel. If the fullness is reduced, the rigidity of the parts will also be reduced. The side panel of a certain model, such as Figure 5 As shown, to maximize the internal dimensions of the vehicle body design, the side panels have a minimal styling, with overall dimensions of 3056×1739×194mm. Furthermore, to maintain lightweight construction, the side panels are only 0.7mm thick. This lack of styling, large dimensions, and thin material thickness contribute to the risk of deformation and quality issues throughout the stamping manufacturing process. A crucial step is part quality repair. Defective side panels can occur during production, requiring polishing and repair to remove surface defects. This process involves handling, positioning, and grinding the side panel parts.

[0003] In the prior art, a rework table for rework of stamping parts is disclosed, with publication number CN210148017U. Figure 5 This is a simple working diagram of the patent. A rework table for rework of stamping parts is a horizontal surface. The side outer panel is installed in the product frame in an upright position after being produced. Before rework of the part, the part needs to be taken out of the product frame and rotated 90°, and the product is placed on the rework table for rework.

[0004] The above-mentioned rework platform is widely used in major stamping workshops, but it is aimed at stamping parts that are relatively small in size, moderate in rigidity, and not easily deformed during transportation and rework. Figure 5 The rear side panel shown in the figure is not suitable for this rework platform. On the one hand, the existing rework workbench is not as large as the product, and the stamping parts cannot be placed on the workbench; on the other hand, there are several risks of deformation of stamping parts in the existing rework process: 1. When the product is taken out of the product box and rotated 90 degrees, the stamping parts will be deformed due to poor rigidity. 2. Figure 5 As shown in the figure, the product is placed horizontally on the rework platform with the center suspended. Due to gravity and weak rigidity, the stamped part will collapse and deform in the middle. 3. After the rework is completed, the worker rotates the stamped part 90 degrees from the horizontal to frame it, which poses a high risk of deformation. Summary of the Invention

[0005] The purpose of the present invention is to provide a fixing mechanism for stamping part rework, so as to solve the problem that the existing rework platform is not applicable to stamping parts that are easy to deform.

[0006] The present invention provides a fixing mechanism for rework of stamped parts, comprising a frame, a limit support assembly, a plurality of limit clamping assemblies, and a movable assembly arranged at the lower end of the frame, wherein the frame comprises a bottom support portion and two mounting portions respectively arranged on both sides of the bottom support portion, at least one limit clamping assembly is provided on the inner side of each mounting portion, the limit clamping assembly is movably connected to the mounting portion, and the limit support assembly is arranged at the upper end of the bottom support portion.

[0007] The above-mentioned fixing mechanism for rework of stamping parts supports the lower end of the stamping part through the limit support assembly on the bottom support part, and fixes the two sides of the stamping part through the limit clamping assembly to achieve the fixation of the stamping part. The stamping part is always in a vertical upright posture during the entire process of being taken out of the product frame, reworked, and framed, which reduces the rotation and transportation of the stamping part, and will not be deformed during the rework process.

[0008] Furthermore, the limiting support assembly includes a plurality of limiting blocks arranged at intervals, and the plurality of limiting blocks are supported at intervals on the edge of the lower end of the stamping part.

[0009] Furthermore, the upper ends of the two mounting portions are connected via a connecting portion.

[0010] Furthermore, the moving assembly includes at least four universal wheels.

[0011] Furthermore, the limiting clamping assembly includes a movable connecting frame, a fixed seat arranged on the inner side of the movable connecting frame, and a fixed clamp arranged on one side of the fixed seat. One end of the fixed clamp is connected to the movable connecting frame in a horizontal direction, and the other end extends to one side of the fixed seat. The movable connecting frame is also provided with a locking handle for fixing the fixed clamp.

[0012] Furthermore, a fixing groove is provided on one side of the fixing seat corresponding to the end of the fixing clamp.

[0013] Furthermore, the locking handle includes a U-shaped rotation locking portion and a handle portion connected to the U-shaped rotation locking portion, the end of the U-shaped rotation locking portion is rotationally connected to the movable connecting frame, and when locked, the fixed clamp is located in the U-shaped rotation locking portion.

[0014] Furthermore, the limiting clamping assembly also includes a movable limiting piece, which is connected to the movable connecting frame and is used to limit the movement of the movable connecting frame. Avoidance holes are provided at positions corresponding to the limiting ends of the movable connecting frame and the movable limiting piece.

[0015] Furthermore, the movable limiting member is a quick clamp, and the end of the quick clamp is arranged toward the avoidance hole.

[0016] Furthermore, the locking rod of the quick clamp includes a threaded tube and a locking rod threadably connected to the threaded tube. BRIEF DESCRIPTION OF THE DRAWINGS

The movable connecting frame 31 is also provided with a locking handle 34 for fixing the fixed clamp 33. During processing, the side of the stamping part 100 is fixed to the fixed base 32, and the other end is clamped by the fixed clamp 33. Finally, the fixed clamp 33 is locked by the locking handle 34 to achieve the fixation of the edge of the stamping part 100.

[0029] In one embodiment of the present invention, a fixing groove 321 is provided on one side of the fixing seat 32 corresponding to the end of the fixing clamp 33 to fix the flange of the stamping part 100 .

[0030] In one embodiment of the present invention, the locking handle 34 includes a U-shaped rotation locking portion 341 and a handle portion 342 connected to the U-shaped rotation locking portion 341. The end of the U-shaped rotation locking portion 341 is rotationally connected to the movable connecting frame 31. When locked, the fixed clamp is located in the U-shaped rotation locking portion.

[0031] In one embodiment of the present invention, the limiting clamping assembly 30 also includes a movable limiting member 35, which is connected to the movable connecting frame 31 and is used to limit the movement of the movable connecting frame 31. An avoidance hole is provided at the position corresponding to the limiting end of the movable connecting frame 31 and the movable limiting member 35.

[0032] In one embodiment of the present invention, the movement limiting member 35 is a quick clamp, and the end of the quick clamp is arranged toward the avoidance hole to achieve a locking function.

[0033] In one embodiment of the present invention, the locking rod of the quick clamp includes a threaded tube 351 and a locking rod 352 threadedly connected to the threaded tube 351, so that the locking force can be adjusted by adjusting the position of the locking rod 352. Specifically, the longer the length of the threaded tube 351 and the locking rod 352, the greater the locking force.

[0034] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
