Description

Technical Field

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

[0002] The rear axle of a car refers to a part of the rear axle, also known as the rear drive axle. It is a crucial component of the vehicle, primarily functioning to bear loads, drive, decelerate, and provide differential protection. Electrophoretic coating is used to process the rear axle. This technology uses an external electric field to cause pigments and resin particles suspended in an electrophoretic solution to migrate directionally and deposit on the surface of a substrate, one of the electrodes, forming a uniform and continuous coating. This coating not only provides rust protection but also enhances the mechanical strength and aesthetics of the steel.

[0003] The prior art, CN220413572U, discloses an electrophoresis fixture for a car rear axle. Addressing the issue that existing electrophoresis fixtures are prone to detachment due to their simple placement, this invention proposes the following solution: A base frame is included. The bottom of the base frame has four rectangular casters, and the top of the base frame has two symmetrically distributed T-shaped grooves. T-shaped blocks are slidably connected inside each of the two T-shaped grooves. This invention allows the two ends of the car rear axle to be fitted into a rectangular frame. Anti-slip pads on two curved plates within the rectangular frame, under the influence of two springs, secure the rear axle. An adjusting assembly can adjust the distance between the two vertical plates. Finally, the T-shaped inserts of the two clamping components are inserted into their corresponding T-shaped sockets to complete the fixing process. The rear axle is effectively fixed under the pressure of multiple springs and the two vertical plates.

[0004] With the above configuration, the existing tooling frame, consisting of a base frame, vertical plates, a top box, and an electric push rod, can fit into a rectangular frame at both ends of the rear axle of a car. Then, the anti-slip pads on the two arc-shaped plates inside the rectangular frame, under the influence of two springs, fix the rear axle. The adjustment assembly can then adjust the distance between the two vertical plates. Finally, the T-shaped inserts of the two clamping components are inserted into their corresponding T-shaped sockets to complete the fixing process. The rear axle of the car can be effectively fixed under the influence of multiple springs and two vertical plates. However, the existing tooling frame has the following drawbacks during operation:

[0005] When using the existing tooling fixture, the rear axle needs to be installed between the arc plates and fixed by springs. Because the rear axle is heavy, the springs are compressed by the arc plates for a long time, causing the springs to deform and the spring force to decrease. This makes it impossible to effectively fix the rear axle, which may cause the rear axle to fall off during movement, affecting the processing of the rear axle. Utility Model Content

[0006] This utility model aims to provide a machining and fixing fixture for automotive rear axles, mainly to solve the technical problem in the prior art where springs are subjected to pressure from the rear axle for a long time, causing spring deformation, reduced elasticity, and inability to effectively fix the rear axle.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A machining fixture for automotive rear axles includes a vertical plate and a T-shaped plate. The surface of the vertical plate has multiple T-shaped grooves, and the T-shaped plate is inserted into these grooves. A concave plate is fixedly connected to one side of the T-shaped plate. Symmetrical slots are formed on the side of the concave plate away from the T-shaped plate. Symmetrical movable cavities are formed on the inner wall of the concave plate. Movable grooves are formed on the inner wall of the movable cavities. A rotating rod is rotatably connected to the inner wall of the movable groove. A convex groove is formed on the inner wall of the rotating rod. A convex block is slidably connected to the inner wall of the convex groove. A threaded rod is fixedly connected to one side of the convex block. The threaded rod passes through the slot and is threadedly connected to it. A clamping plate is rotatably connected to the end of the threaded rod away from the convex block. A linkage assembly is installed on the inner wall of the movable cavity.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When electrophoretic coating is required on the rear axle, first insert both ends of the rear axle into the slots in the concave plate. Then adjust the linkage assembly so that the rotating block drives the connecting block to rotate, the connecting block drives the first gear to rotate, the first gear drives the rotating rod and the second gear to rotate, and the second gear drives the connecting rod to rotate. This causes the rotating rod to drive the threaded rod to rotate through the convex block, so that the threaded rod is threadedly connected to the concave plate, allowing the threaded rod to move. This causes the threaded rod to push the clamping plate to move, so that the clamping plate clamps the outer wall of the rear axle. Then, insert the T-shaped plate with the concave plate into the T-slot, and then limit the T-shaped plate by the actuating block. Then, the rear axle can be electrophoretically coated.

[0011] 2. Beneficial effects:

[0012] Existing technology, through the setup of a base frame, vertical plates, a top box, and an electric push rod, allows rectangular frames to be fitted onto both ends of the rear axle of a vehicle. Anti-slip pads on two curved plates within the rectangular frames, under the influence of two springs, secure the rear axle. An adjusting assembly then adjusts the distance between the two vertical plates. Finally, the T-shaped inserts of the two clamping components are plugged into their corresponding T-shaped sockets to complete the fixing process. This technology effectively secures the rear axle under the influence of multiple springs and two vertical plates. However, in existing tooling, the rear axle needs to be installed between the curved plates and secured by springs. Because the rear axle is heavy, prolonged pressure from the curved plates on the springs causes deformation, reducing the spring force. The inability to effectively secure the rear axle during movement can lead to it falling off, affecting its machining. This solution addresses this issue by incorporating a concave plate, rotating rod, convex block, threaded rod, clamping plate, first gear, second gear, and connecting rod. Rotating the rotating block causes the first gear to drive the second gear, which in turn moves the threaded rod, which in turn drives the connecting rod. The rising and falling of the threaded rod causes the clamping plate to clamp the outer wall of the rear axle. A T-shaped plate with a concave plate is then inserted into the T-slot and limited by a moving block. This solution resolves the issue of the rear axle falling off due to instability, improving its securing effect and machining efficiency.

[0013] Preferably, the linkage assembly includes a first gear rotatably connected to the inner wall of the movable cavity, and fixedly connected to one end of a rotating rod. A second gear is rotatably connected to the inner wall of the movable cavity, meshing with the first gear. A connecting rod is fixedly connected between the two second gears, and rotatably connected to a concave plate. A connecting block is fixedly connected to the side of the first gear away from the rotating rod, passing through and rotatably connected to the concave plate. A rotating block is fixedly connected to the end of the connecting block away from the first gear. By setting the linkage assembly, the upper and lower clamping plates can move synchronously, making the fixation of the rear axle more stable.

[0014] Preferably, the outer wall of the vertical plate has a rotating groove, and a round rod is rotatably connected to the inner wall of the rotating groove. One end of the round rod is fixedly connected to a lever block. By setting the lever block and the round rod, the T-shaped plate can be limited to prevent it from slipping.

[0015] Preferably, the inner wall of the slot has a guide groove, and a guide rod is slidably connected to the inner wall of the guide groove. One end of the guide rod is fixedly connected to the outer wall of the clamping plate. By setting the guide rod, the clamping plate can be limited to move only up and down.

[0016] Preferably, the upper end of the actuating block is smaller than the lower end, and the weight of the lower end of the actuating block is greater than the weight of the upper end. This ensures that the actuating block is always in a vertical position.

[0017] Preferably, the inner wall of the clamping plate is fixed with an anti-slip pad, which improves the fixation effect of the rear axle.

[0018] Preferably, the outer wall of the rotating block has anti-slip textures to increase the friction between the fingers and the rotating block. Attached Figure Description
