Technical Field
[0001] This invention belongs to the technical field of vehicle body bracket processing devices, and specifically relates to a vehicle body connecting bracket processing device. Background Technology
[0002] Body mounting brackets are important support components used to install and fix various functional component assemblies such as steering supports. The quality of their processing directly affects the installation and positioning accuracy and connection reliability of various functional component assemblies. For example, the automotive motor mounting bracket is a type of body mounting bracket used to install automotive motors, and its processing quality affects the stability of automotive motors.
[0003] Automotive motor mounting brackets are generally set in the shape of Figure 1 As shown in the structure, ear plates are symmetrically welded to both sides of the circular workpiece. In the actual welding process, in order to ensure the stability of the suspension bracket, the ear plates need to be positioned using a positioning mechanism to ensure that their center is on the same plane as the center of the circular workpiece. However, the width of the circular workpiece is greater than the width of the ear plates. Therefore, it is crucial to ensure that the ear plates can always be on the same horizontal plane as the center of the circular workpiece during welding. Summary of the Invention
[0004] The purpose of this invention is to provide a vehicle body connecting bracket processing device to solve the above-mentioned technical problems.
[0005] A vehicle body connecting bracket processing device includes a worktable, a circular workpiece positioning mechanism, and an ear plate positioning mechanism. The circular workpiece positioning mechanism is located above the worktable and is used to fix the circular workpiece. The ear plate positioning mechanism is located outside the circular workpiece and is used to keep the ear plate and the center of the circular workpiece in the same horizontal plane and to press the ear plate against the side of the circular workpiece.
[0006] Preferably, the ear plate positioning mechanism includes a moving component and a positioning component. The positioning component places the ear plate and drives the ear plate to rise and fall so that the ear plate and the center of the circular workpiece are on the same straight line. The moving component is located on both sides of the positioning component and pushes the ear plates on both sides so that the ear plates are in close contact with the outer side of the circular workpiece.
[0007] Preferably, the moving assembly includes a first moving seat, a second moving seat, and a bidirectional screw. Fixed seats are symmetrically fixedly connected to both sides of the bottom of the worktable, and the bidirectional screw is rotatably connected between the two fixed seats. The threaded sections on both sides of the bidirectional screw are respectively threadedly connected to the first moving seat and the second moving seat. The top of the worktable is provided with a sliding groove that is slidably connected to the first moving seat and the second moving seat. The first moving seat and the second moving seat are respectively located on both sides of the circular workpiece positioning mechanism, and the first moving seat and the second moving seat move towards each other so that the ear plate is tightly attached to the side of the circular workpiece.
[0008] Preferably, both the first and second movable seats include a movable body and a guide rail. The guide rail is threadedly connected to the bidirectional screw via a lead screw seat. The movable body is slidably connected to one side of the guide rail. The guide rail has an U-shaped structure. The return spring is provided between the movable body and the inner top of the guide rail.
[0009] Preferably, the positioning component includes a fixed platform, an I-shaped bracket, and a tray. A base is fixedly connected between the two fixed seats, and the fixed platform is fixedly connected to the middle of the base. The bidirectional screw passes through the fixed platform and is rotatably connected to the fixed platform. The top of the fixed platform is fixedly connected to the I-shaped bracket by means of a lifting cylinder, and the tray is symmetrically fixedly connected to both sides of the I-shaped bracket. The lifting cylinder drives the I-shaped bracket to rise and fall so that the center of the tray and the center of the circular workpiece are kept in the same plane.
[0010] Preferably, the circular workpiece positioning mechanism includes a fixed column and a sliding column. Fixed brackets are fixedly connected to the corners of the worktable, and telescopic cylinders are fixedly connected to the top of the fixed brackets. The sliding column is fixedly connected to the movable end of the telescopic cylinder. The sliding column is slidably inserted into the fixed column. Multiple limiting grooves are opened on the side wall of the fixed column along its circumference. A wedge block is slidably connected inside the limiting groove. One side of the wedge block is located inside the fixed column. The sliding column pushes the wedge block to move outward so that the wedge block presses against the inner wall of the circular workpiece.
[0011] Preferably, the wedge block includes a pressing block, a sliding rod, a spring, and a pressure-receiving block. The sliding rod is fixedly connected between the pressing block and the pressure-receiving block, and the spring is sleeved on the outer side of the sliding rod. The pressure-receiving block and the pressing block are located inside and outside the fixed post, respectively. The top of the pressure-receiving block has an inclined structure, and the sliding rod is slidably connected to the groove.
[0012] The present invention has the following advantages:
[0013] This invention includes a circular workpiece positioning mechanism and an ear plate positioning mechanism. The circular workpiece is fitted onto a fixed post, and a movable wedge block presses against the side wall of the circular workpiece. This serves two purposes: firstly, it can press against circular workpieces of different sizes, and secondly, it provides internal support for the circular component, preventing the ear plate from excessively compressing and deforming the workpiece. The ear plate positioning mechanism moves ear plates of different sizes up and down to accommodate ear plates of varying heights, aligning the center of the ear plate with the center of the circular workpiece for easy subsequent fixing. A moving component pushes the positioned ear plate to move, ensuring it is tightly against the side wall of the circular workpiece, facilitating subsequent welding. This invention fixes the circular workpiece and ear plates separately and allows control over the raising and lowering of the ear plates to keep them aligned with the center of the circular workpiece.

[0026] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.
[0027] like Figure 2-6 The illustrated vehicle body connecting bracket processing device includes a worktable, a circular workpiece positioning mechanism 2, and an ear plate positioning mechanism 3. The circular workpiece positioning mechanism 2 is located above the worktable and is used to fix the circular workpiece. The ear plate positioning mechanism 3 is located outside the circular workpiece and is used to keep the ear plate and the center of the circular workpiece in the same horizontal plane and to press the ear plate against the side of the circular workpiece.
[0028] The ear plate positioning mechanism 3 includes a moving component 30 and a positioning component 31. The positioning component 31 places the ear plate and drives the ear plate to rise and fall so that the ear plate and the center of the circular workpiece are on the same straight line. The moving component 30 is located on both sides of the positioning component 31 and pushes the ear plates on both sides so that the ear plates are in close contact with the outer side of the circular workpiece.
[0029] The moving component 30 includes a first moving seat 303, a second moving seat 304, and a bidirectional screw 301. Fixed seats 300 are symmetrically fixedly connected to both sides of the bottom of the worktable, and the bidirectional screw 301 is rotatably connected between the two fixed seats 300. The threaded sections on both sides of the bidirectional screw 301 are respectively threadedly connected to the first moving seat 303 and the second moving seat 304. The top of the worktable is provided with a sliding groove 305 that is slidably connected to the first moving seat 303 and the second moving seat 304. The first moving seat 303 and the second moving seat 304 are respectively located on both sides of the circular workpiece positioning mechanism, and the first moving seat 303 and the second moving seat 304 move towards each other so that the ear plate is tightly attached to the side of the circular workpiece.
[0030] The moving assembly 30 includes a first moving seat 303 and a second moving seat 304 that move in opposite directions. Since both sides of the circular workpiece need to be fixed with ear plates, a bidirectional screw 301 is provided at the bottom of the worktable. The forward rotation of the bidirectional screw 301 can drive the first moving seat 303 and the second moving seat 304 to move in opposite directions. In turn, the first moving seat 303 and the second moving seat 304 push the ear plates on both sides to move towards the circular workpiece, so that the ear plates are tightly attached to the side wall of the circular workpiece. The reverse movement of the bidirectional screw 301 can drive the first moving seat 303 and the second moving seat 304 to move in opposite directions. This makes it easier to loosen the processed suspension bracket and remove the processed suspension bracket.
[0031] Both the first movable seat 303 and the second movable seat 304 include a movable body 306 and a guide rail 308. The guide rail 308 is threadedly connected to the bidirectional screw 301 via a lead screw seat. The movable body 306 is slidably connected to one side of the guide rail 308. The guide rail 308 has an U-shaped structure. The return spring 309 is provided between the movable body 306 and the inner top of the guide rail 308.
[0032] The movable seat 303 and movable seat 304 are configured as a guide rail 308 and a movable body 306, mainly to accommodate ear plates of different sizes. The movable body 306 has a sloping structure at the junction with the ear plate, which is also to accommodate the top shape of the ear plate. The inner top of the movable body 306 and the guide rail 308 is provided with a groove 307, and the end of the ear plate is confined in the groove 307. When the size of the entire suspension bracket is large, the size of the ear plate will also be larger. The end of the ear plate is inserted into the groove 307. As the bidirectional screw 301 continues to rotate, the movable seat 303 and movable seat 304 still move towards the circular workpiece, and then use the ear plate to push the movable body 306 to move towards each other, causing the return spring 309 to contract. In this way, the reverse force of the return spring 309 can also press the movable body 306 against the top of the ear plate to prevent the ear plate from moving.
[0033] The positioning assembly 31 includes a fixed platform 310, an I-shaped bracket 312, and a support plate 313. A base is fixedly connected between the two fixed seats 300, and the fixed platform 310 is fixedly connected to the middle of the base. A bidirectional screw 301 passes through the fixed platform 310 and is rotatably connected to the fixed platform. The top of the fixed platform 310 is fixedly connected to the I-shaped bracket 312 by means of a lifting cylinder 311, and the support plate 313 is symmetrically fixedly connected to both sides of the I-shaped bracket 312. The lifting cylinder 311 drives the I-shaped bracket 312 to rise and fall so that the center of the support plate 313 is in the same plane as the center of the circular workpiece.
[0034] The positioning component 31 is used to synchronously drive the lifting and lowering of the two side ear plates. The bidirectional screw 301 passes through the fixed platform 310. Because the rotation of the bidirectional screw 301 will not affect the stability of the fixed platform 310, the lifting cylinder 311 can drive the I-shaped bracket 312 to move up and down, which in turn can drive the support plates 313 on both sides of the I-shaped bracket 312 to move. The movement of the support plates 313 can drive the ear plates placed on top of them to rise and fall, so that the center of the ear plates is aligned with the center of the circular workpiece, which is convenient for subsequent fixing of the ear plates.
[0035] The circular workpiece positioning mechanism 2 includes a fixed column 20 and a sliding column 21. Fixed brackets 24 are fixedly connected to the corners of the worktable, and telescopic cylinders 22 are fixedly connected to the top of the fixed brackets 24. The sliding column 21 is fixedly connected to the movable end of the telescopic cylinder 22. The sliding column 21 is slidably inserted into the fixed column 20. Multiple limiting grooves are opened on the side wall of the fixed column 20 along its circumference. A wedge block 23 is slidably connected inside the limiting groove. One side of the wedge block 23 is located inside the fixed column 20. The sliding column 21 pushes the wedge block 23 to move outward so that the wedge block 23 presses against the inner wall of the circular workpiece. The wedge block 23 includes a pressing block 25, a sliding rod 26, a spring 27, and a pressure block 28. The sliding rod 26 is fixedly connected between the pressing block 25 and the pressure block 28, and the spring 27 is sleeved on the outside of the sliding rod 26. The pressure block 28 and the pressing block 25 are located inside and outside the fixed column 20, respectively. The top of the pressure block 28 has an inclined structure, and the sliding rod 26 is slidably connected to the groove.
[0036] During welding, the circular workpiece of the automotive motor mounting bracket is first placed outside the fixed post 20. At this time, it is not necessary to swing the position of the circular workpiece. The telescopic cylinder 22 drives the sliding post 21 to move down, so that the sliding post 21 moves into the fixed post 20. The bottom of the sliding post 21 has a conical structure and is in contact with the pressure block 28. The top of the pressure block 28 has a sloping structure. As the sliding post 21 moves down, it can push the pressure block 28 to move, which in turn can push the slide rod 26 to move outward of the fixed post 20. At the same time, the spring 27 on the surface of the slide rod 26 is compressed and stores energy. The movement of the slide rod 26 can drive the pressure block 25 to move outward, so that the pressure block 25 presses against the inner wall of the circular workpiece. Since there are multiple pressure blocks 25, the inside of the circular workpiece is pressed by the pressure blocks 25, and its inner wall is supported by the pressure blocks 25, which prevents deformation when the ear plate is pressed later. Furthermore, the circular workpiece can be positioned by fixing it with the pressure blocks 25.
[0037] Working Principle: During welding, the circular workpiece of the automotive motor mounting bracket is first placed outside the fixed post 20. At this point, it is not necessary to swing the position of the circular workpiece. The telescopic cylinder 22 drives the sliding post 21 to move downward, so that the sliding post 21 moves into the fixed post 20. The bottom of the sliding post 21 has a conical structure and is in contact with the pressure block 28. The top of the pressure block 28 has a sloping structure. As the sliding post 21 moves downward, it can push the pressure block 28 to move, which in turn can push the sliding rod 26 to move outward from the fixed post 20. At the same time, the spring 27 on the surface of the sliding rod 26 is compressed and stores energy. The movement of the sliding rod 26 can drive the pressing block 25 to move outward, so that the pressing block 25 presses against the inner wall of the circular workpiece. Since there are multiple pressing blocks 25, the inside of the circular workpiece is pressed by the pressing blocks 25, and its inner wall is supported by the pressing blocks 25, preventing damage when the ear plate is pressed later. The circular workpiece is deformed and fixed by the pressure block 25, which can achieve the positioning of the circular workpiece. The lifting cylinder 311 can drive the I-shaped bracket 312 to move up and down, which in turn can drive the support plates 313 on both sides of the I-shaped bracket 312 to move. The movement of the support plates 313 can drive the ear plates placed on top to rise and fall, so that the center of the ear plates is aligned with the center of the circular workpiece, which is convenient for subsequent fixing of the ear plates. The forward rotation of the bidirectional screw 301 can drive the moving seat 1 303 and the moving seat 2 304 to move towards each other, and then the moving seat 1 303 and the moving seat 2 304 push the ear plates on both sides towards the circular workpiece, so that the ear plates are tightly attached to the side wall of the circular workpiece. The reverse movement of the bidirectional screw 301 can drive the moving seat 1 303 and the moving seat 2 304 to move in the opposite direction, which is convenient for loosening the processed suspension bracket, which is convenient for removing the processed suspension bracket.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
