Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle parts processing technology, specifically a fixture for processing the gearbox housing of a new energy commercial vehicle. Background Technology

[0002] The gearbox housing for new energy commercial vehicles is a core component designed specifically for electric or hybrid commercial vehicles. It is typically made of high-strength, lightweight materials, such as aluminum alloys or composite materials, and has excellent sealing, heat dissipation, and structural stability. Its design must take into account the high torque output characteristics of the motor. Through precision casting or machining processes, a compact and integrated layout is achieved, which effectively reduces the weight of the entire vehicle and improves energy efficiency. At the same time, it enhances vibration resistance and corrosion resistance to adapt to complex working conditions and meet the comprehensive requirements of new energy commercial vehicles for efficient transmission, long service life, and low carbon emissions.

[0003] During the production process, the housing of the gearbox for new energy commercial vehicles needs to be machined with high precision using a special machining fixture. The fixture adopts high-rigidity materials and modular design, combined with a precision positioning and clamping system, to ensure that the housing is in a stable state during processing, effectively reducing clamping deformation and adapting to complex geometric features.

[0004] According to CN222767862U, "A machining fixture for the rear housing of a new energy gearbox", three hydraulic clamping fixtures arranged in a triangular structure are embedded and installed on the top of the base plate. A hydraulic clamping fixture 2 is arranged between the two hydraulic clamping fixtures 1 on the left and rear sides. A support cylinder is arranged directly below the pressure plate of the hydraulic clamping fixture 2. A support cylinder is arranged on the side of the hydraulic clamping fixture 1 on the right rear side. Three evenly distributed guide rods are also arranged on the top of the base plate. A positioning seat 1 and a positioning seat 2 are respectively arranged between the hydraulic clamping fixture 2 and the two adjacent hydraulic clamping fixtures 1. The clamping fixtures 1 and 2 can ensure that the workpiece is accurately positioned and firmly clamped in the specified position. They can also reduce vibration and deformation during processing through floating support, and can also ensure accurate positioning during precision machining. They can also complete the support, clamping and rapid release that cannot be completed by manual fixtures.

[0005] The above-mentioned device clamps and fixes the workpiece at multiple points using multiple clamps, but it still has the following shortcomings:

[0006] In the prior art, the gearbox housing of new energy commercial vehicles is an irregular shape with an uneven surface and varying structural strength at each location. When the aforementioned device fixes the gearbox housing of new energy commercial vehicles, the protruding part of the gearbox housing is suspended in the air, resulting in poor support in some areas. This can easily cause vibration or deformation during processing, affecting the processing accuracy.

[0007] Therefore, we propose a fixture for machining the gearbox housing of new energy commercial vehicles to solve the problems mentioned above. Utility Model Content

[0008] The purpose of this utility model is to provide a fixture for processing the gearbox housing of new energy commercial vehicles, so as to solve the problem mentioned in the background art of not being able to support the bottom of the gearbox housing of new energy commercial vehicles.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0010] A jig for processing a gearbox housing of a new energy commercial vehicle includes a base plate. A rotating mechanism for adjusting the angle of the gearbox housing is disposed on the top of the base plate. A rotatable main frame is disposed at the rotating end of the rotating mechanism. A clamping mechanism for fixing the gearbox housing is disposed on the surface of the main frame. A plurality of support rods for supporting the bottom of the gearbox housing are slidably connected inside the main frame. A plurality of springs are disposed at one end of each support rod to drive the support rod to adapt to the shape of the bottom of the gearbox housing. A lifting mechanism for moving the plurality of support rods as a whole is disposed inside the main frame. A locking mechanism for fixing the support rods is disposed inside each support rod.

[0011] The rotating mechanism includes a geared disc rotatably connected to the surface of the base plate, a rack engaging with the surface of the geared disc to drive the geared disc to rotate, an adjusting bolt rotatably connected inside the base plate to drive the rack to move, the bottom of the main board frame being fixedly connected to the surface of the geared disc, and the rack slidably connected to the surface of the base plate.

[0012] The clamping mechanism includes a bidirectional screw rotatably connected to the surface of the main board frame. A motor is fixedly connected to one side of the main board frame. The motor output shaft is fixedly connected to one end of the bidirectional screw. Clamping plates that can move relative to each other are threaded onto both sides of the surface of the bidirectional screw.

[0013] The clamping plate is fixedly connected to both sides of the gearbox housing to prevent indentations.

[0014] The lifting mechanism includes an adjusting bolt two rotatably connected to one side of the main board frame. The surface of the adjusting bolt two is threaded with a lifting frame that can be raised and lowered. The lifting frame is slidably connected inside the main board frame.

[0015] Several support rods are slidably connected inside the lifting frame, and one end of several springs is fixedly connected inside the lifting frame. Sliding holes for the support rods are provided on the surface of the main board frame corresponding to the support rods.

[0016] Each end of the support rod that contacts the bottom of the gearbox housing is fixedly connected with a rubber pad for cushioning.

[0017] The locking mechanism includes a rack two fixedly connected inside the support rod, one end of which is engaged with a gear, and the gear is rotatably connected inside the support rod.

[0018] A locking disc is provided on one side of the gear. The locking disc and the gear have interlocking locking grooves on their corresponding sides. A moving rod that drives the locking disc to move is fixedly connected to the inner wall of the locking disc. The gear is rotatably connected to the surface of the moving rod, and the moving rod is slidably connected inside the lifting frame.

[0019] One end of the moving rod is fixedly connected to a sliding plate that drives the moving rod to slide. One end of the sliding plate is rotatably connected to an adjusting bolt three that drives the sliding plate to move. The adjusting bolt three is threadedly connected to one side of the lifting frame.

[0020] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0021] This invention places the gearbox housing of a new energy commercial vehicle on the surface of a main frame. A motor drives a bidirectional screw to rotate, causing the screw to move relative to the clamping plate, thus clamping and fixing the gearbox housing on the main frame surface. Rotating the second adjusting bolt causes the lifting frame to slide inside the main frame, allowing several support rods to slide out through sliding holes on the main frame surface and contact the bottom of the gearbox housing. Rubber pads prevent scratching the bottom of the gearbox housing. Several springs drive several support rods to adapt the shape of the bottom of the gearbox housing. Rotating the third adjusting bolt causes the sliding plate to move, which in turn moves the moving rod inside the lifting frame. The moving rod moves the locking disc, causing the locking disc to engage the locking groove with the locking groove on one side of the gear, thus fixing the gear. Since the support rod moves while lifting, it also moves the rack, which in turn drives the gear to rotate. By fixing the gear, the support rod is fixed, providing stable support for the bottom of the gearbox housing during processing, preventing local areas from being suspended, improving processing stability, and thus improving processing accuracy.

[0022] By rotating the adjusting bolt, the adjusting bolt drives the rack to move, causing the rack to rotate the gear plate on the base plate surface. At the same time, it drives the main plate frame to rotate, allowing the workpiece on the main plate frame surface to be angled, thus improving the flexibility of workpiece processing.

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.

[0030] Please see Figure 1-5 This utility model provides a technical solution:

[0031] like Figure 1 and Figure 2 As shown, a jig for processing a gearbox housing of a new energy commercial vehicle includes a base plate 1. A rotating mechanism for adjusting the angle of the gearbox housing is provided on the top of the base plate 1. A rotatable main frame 2 is provided at the rotating end of the rotating mechanism. A clamping mechanism for fixing the gearbox housing is provided on the surface of the main frame 2. A plurality of support rods 3 for supporting the bottom of the gearbox housing are slidably connected inside the main frame 2. A plurality of springs 4 are provided at one end of each support rod 3 to drive the support rod 3 to adapt to the shape of the bottom of the gearbox housing. A lifting mechanism for moving the plurality of support rods 3 as a whole is provided inside the main frame 2. A locking mechanism for fixing the support rods 3 is provided inside the support rods 3.

[0032] like Figure 1 and Figure 2As shown, by placing the new energy commercial vehicle gearbox housing on the surface of the main board frame 2, the clamping mechanism is activated to fix the workpiece, and then the lifting mechanism is activated to drive several support rods 3 to contact the bottom of the workpiece, so that several springs 4 drive several support rods 3 to contact and adapt to the shape of the bottom of the workpiece. After completion, the locking mechanism is activated to fix the support rods 3, so that the support rods 3 support the bottom of the workpiece, thus completing the support of the bottom of the new energy commercial vehicle gearbox housing. This ensures stable support during processing and prevents local areas from being suspended, improving processing stability and thus improving processing accuracy. The rotating mechanism can drive the main board frame 2 to rotate on the bottom surface, allowing the workpiece on the surface of the main board frame 2 to be angled, improving the flexibility of workpiece processing.

[0033] Furthermore, such as Figure 1 and Figure 3 As shown, the rotating mechanism includes a gear disk 5 rotatably connected to the surface of the base plate 1. A rack 6 meshes with the surface of the gear disk 5 to drive the gear disk 5 to rotate. An adjusting bolt 7 is rotatably connected inside the base plate 1 to drive the rack 6 to move. The surface of the gear disk 5 is fixedly connected to the bottom of the main board frame 2, and the rack 6 is slidably connected to the surface of the base plate 1.

[0034] By rotating the adjusting bolt 7, the adjusting bolt 7 drives the rack 6 to move, causing the rack 6 to drive the gear plate 5 to rotate on the surface of the base plate 1, and at the same time drive the main plate frame 2 to rotate. The workpiece on the surface of the main plate frame 2 can be angled, improving the flexibility of workpiece processing.

[0035] Furthermore, such as Figures 1-3 As shown, the clamping mechanism includes a bidirectional screw 11 rotatably connected to the surface of the main board frame 2. A motor 10 is fixedly connected to one side of the main board frame 2. The output shaft of the motor 10 is fixedly connected to one end of the bidirectional screw 11. Both sides of the surface of the bidirectional screw 11 are threaded with clamping plates 12 that can move relative to each other. Both sides of the surface of the clamping plates 12 that contact the gearbox housing are fixedly connected with buffer pads 13 to prevent indentations.

[0036] The motor 10 drives the bidirectional screw 11 to rotate, which causes the bidirectional screw 11 to move the clamping plate 12 relative to each other, clamping and fixing the gearbox housing located on the surface of the main board frame 2. At the same time, the buffer pad 13 can prevent indentations from being pressed into the gearbox housing.

[0037] Furthermore, such as Figures 1-5As shown, the lifting mechanism includes an adjusting bolt 28 rotatably connected to one side of the main board frame 2. The surface of the adjusting bolt 28 is threaded with a lifting frame 9 that can be raised and lowered. The lifting frame 9 is slidably connected inside the main board frame 2. Several support rods 3 are slidably connected inside the lifting frame 9. One end of several springs 4 is fixedly connected inside the lifting frame 9. The surface of the main board frame 2 corresponding to the support rods 3 is provided with sliding holes adapted to the support rods 3. The end of the support rod 3 that contacts the bottom of the gearbox housing is fixedly connected with a rubber pad 14 for buffering.

[0038] Rotate the adjusting bolt 28 to make the adjusting bolt 28 drive the lifting frame 9 to slide inside the main board frame 2, so that several support rods 3 slide out through the sliding holes on the surface of the main board frame 2 and contact the bottom of the gearbox housing. The rubber pad 14 prevents the bottom of the gearbox housing from being scratched, and several springs 4 drive several support rods 3 to adapt the shape of the bottom of the gearbox housing.

[0039] Furthermore, such as Figures 2-5 As shown, the locking mechanism includes a rack 15 fixedly connected inside the support rod 3. One end of the rack 15 is engaged with a gear 16, which is rotatably connected inside the support rod 3. A locking disc 17 is provided on one side of the gear 16. Locking grooves 18 are provided on the corresponding side of the locking disc 17 and the gear 16. A moving rod 19 is fixedly connected to the inner wall of the locking disc 17 to drive the locking disc 17 to move. The gear 16 is rotatably connected to the surface of the moving rod 19. The moving rod 19 is slidably connected inside the lifting frame 9. A sliding plate 20 is fixedly connected to one end of the moving rod 19 to drive the moving rod 19 to slide. An adjusting bolt 21 is rotatably connected to one end of the sliding plate 20 to drive the sliding plate 20 to move. The adjusting bolt 21 is threadedly connected to one side of the lifting frame 9.

[0040] Rotate the adjusting bolt 3 21, causing the adjusting bolt 3 21 to move the sliding plate 20. The movement of the sliding plate 20 causes the moving rod 19 to move inside the lifting frame 9. The moving rod 19 causes the locking disc 17 to move, causing the locking disc 17 to engage the locking groove 18 with the locking groove 18 on one side of the gear 16, thus fixing the gear 16. Since the support rod 3 will move the rack 2 15 while it is lifting, the rack 2 15 will drive the gear 16 to rotate. By fixing the gear 16, the support rod 3 can be fixed, thus supporting the bottom of the gearbox housing.

[0041] The working principle of this fixture for machining the gearbox housing of new energy commercial vehicles is as follows:

[0042] By placing the new energy commercial vehicle gearbox housing on the surface of the main board frame 2, the motor 10 drives the bidirectional screw 11 to rotate, causing the bidirectional screw 11 to move the clamping plate 12 relative to each other, thus clamping and fixing the gearbox housing located on the surface of the main board frame 2. Rotating the adjusting bolt 2 8 causes the adjusting bolt 2 8 to drive the lifting frame 9 to slide inside the main board frame 2, allowing several support rods 3 to slide out through the sliding holes on the surface of the main board frame 2 and contact the bottom of the gearbox housing. Rubber pads 14 prevent scratching the bottom of the gearbox housing. Several springs 4 drive several support rods 3 to adapt the shape of the bottom of the gearbox housing. Rotating the adjusting bolt 3 21 causes the adjusting bolt 3 21 to... The sliding plate 20 is moved, which in turn moves the moving rod 19 inside the lifting frame 9. The moving rod 19 moves the locking disc 17, which in turn engages the locking groove 18 with the locking groove 18 on one side of the gear 16, thus fixing the gear 16. As the support rod 3 moves, it also moves the rack 15, which in turn rotates the gear 16. By fixing the gear 16, the support rod 3 can be fixed, thus supporting the bottom of the gearbox housing. This ensures stable support during processing, preventing local areas from being suspended, improving processing stability, and consequently improving processing accuracy.

[0043] By rotating the adjusting bolt 7, the adjusting bolt 7 drives the rack 6 to move, causing the rack 6 to drive the gear plate 5 to rotate on the surface of the base plate 1, and at the same time drive the main plate frame 2 to rotate. The workpiece on the surface of the main plate frame 2 can be angled, improving the flexibility of workpiece processing.

[0044] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
