Description

A tooling fixture for the inner rear panel of an automobile Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a tooling fixture for the inner rear panel of an automobile. Background Technology

[0002] The rear inner panel is an important component of a car's body structure, primarily located at the rear of the vehicle (trunk area), and is part of the body frame. It typically works in conjunction with the rear outer panel (the visible rear bumper and taillight surround panels) to form the supporting structure and overall appearance of the rear of the vehicle. It serves to separate the exterior of the vehicle from the interior of the trunk. Its key function is to absorb the impact force in the event of a rear-end collision, thereby reducing the severity of injuries to the occupants. The manufacturing process of the rear inner panel requires appropriate tooling and fixtures for fixation, followed by drilling or painting.

[0003] A tooling fixture for the inner rear panel of an automobile disclosed in Chinese Patent CN219945941U includes a base plate with two vertical plates sliding on the top of the base plate. The two vertical plates are symmetrically arranged. A sliding mechanism for sliding the two vertical plates is provided at the temporal part of the base plate. Limiting frames are provided on opposite sides of the two vertical plates. A rotating shaft is fixedly connected to the surface of the two limiting frames. A first bushing is sleeved on the surface of the two rotating shafts. The two first bushings are respectively sleeved inside the two vertical plates. A clamping mechanism is provided inside the two limiting frames. A worm gear is rotatably connected to one side of one of the vertical plates. The worm gear is fixedly connected to one end of one of the rotating shafts.

[0004] However, compared with existing technologies and comparative solutions, this tooling fixture still has the following problems in actual use:

[0005] When this tooling fixture rotates the inner rear panel of a car, it requires the simultaneous rotation of the crank handles on two upright plates. When the crank handles on the two upright plates rotate out of sync, a speed difference will occur on the two sides of the inner rear panel that are fixed during rotation. Once this happens, the inner rear panel will be subjected to the torque generated by the speed difference on the two sides that are fixed, which may cause the inner rear panel to be twisted and deformed, affecting the quality of the processed inner rear panel. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a tooling fixture for the inner rear panel of an automobile.

[0007] The purpose of this utility model is achieved through the following technical solution: a tooling fixture for the inner rear panel of an automobile, including a base, a first tooling mechanism and a second tooling mechanism are provided on the top of the base, the structure of the second tooling mechanism is the same as the structure of the first tooling mechanism, and the second tooling mechanism and the first tooling mechanism are symmetrically distributed on the top of the base.

[0008] A first driving component and a second driving component are fixedly installed on one side of the base. The output end of the first driving component is fixedly connected to a bidirectional screw, and the output end of the second driving component is fixedly connected to a spline shaft.

The first slide groove and the second slide groove are symmetrically distributed in the middle of the top of the base, and a limit component is fixedly installed in the middle of the third slide groove.

[0011] Preferably, the two ends of the bidirectional screw are rotatably connected inside the first and second slide grooves, respectively, the spline shaft is rotatably connected inside the third slide groove, and a slide shaft is fixedly connected inside the fourth slide groove.

[0030] As shown in Figures 1, 4, and 5, the first tooling mechanism 2 includes a connecting plate 201, a first connecting block 202, a second connecting block 203, a third connecting block 204, a slot 205, a first transmission wheel 206, a second transmission wheel 207, a tensioning wheel 208, a transmission component 209, a spline hole 210, and a clamping assembly 211.

The first transmission wheel 206 is slidably connected to the spline shaft 19 through the spline hole 210. A clamp assembly 211 is provided on one side of the second transmission wheel 207.

[0031] As shown in Figure 4, in this embodiment, the clamp assembly 211 includes a connecting frame fixedly connected to the second transmission wheel 207. A second screw is threadedly connected to one side of the connecting frame. A second adjusting head is fixedly connected to one end of the second screw. A fixing plate is rotatably connected to the end of the second screw away from the second adjusting head. In other embodiments, the clamp assembly 211 can also be a pneumatic clamp or an electric clamp. Pneumatic clamps and electric clamps are both existing technologies.

[0032] The work process is as follows:

[0033] S1. When in use, first start the first drive component 16. The first drive component 16 drives the first tooling mechanism 2 and the second tooling mechanism 3 to move through the bidirectional screw 18.

[0034] S2. When the distance between the first tooling mechanism 2 and the second tooling mechanism 3 is adapted to the inner rear panel of the automobile to be processed, the inner rear panel of the automobile is fixed by the clamping assembly 211 on the first tooling mechanism 2 and the second tooling mechanism 3.

[0035] S3. When it is necessary to rotate the inner panel of the rear of the car during the processing, the second drive component 17 is activated. The second drive component 17 drives the spline shaft 19 to rotate, the spline shaft 19 drives the first transmission wheel 206 to rotate, the first transmission wheel 206 drives the second transmission wheel 207 to rotate through the transmission component 209, and the second transmission wheel 207 drives the inner panel of the rear of the car to rotate through the clamping assembly 211, so as to facilitate painting or drilling at different positions of the inner panel of the rear of the car.

[0036] S4. After rotating to the position to be processed, turn off the second drive component 17 and rotate the first adjusting head 153. The first adjusting head 153 drives the first screw 152 to rotate. The first screw 152 drives the contact component 155 to slide in the third slide groove 13 through the rotating component 154, so that the contact component 155 abuts against the spline shaft 19 to fix the position of the inner panel of the rear of the car, so as to prevent the inner panel of the rear of the car from rotating after being subjected to force during the processing, and to ensure the stability during processing.

[0037] S5. When rotating the inner rear panel of the car, both ends of the inner rear panel rotate synchronously without any speed difference. This avoids the situation where the inner rear panel of the car is twisted or deformed due to asynchronous rotation or speed difference between the two ends of the inner rear panel, thus ensuring the quality of the processed inner rear panel of the car.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
