Description

Technical Field

[0001] The utility model relates to the technical field of power-on testing for automotive center control instrument panels, and specifically to a jig for power-on testing of automotive center control instrument panels. Background Technique

[0002] During the production process of automobiles, workers on the automobile production line need to monitor various automobile parts. Taking the automotive center control instrument panel as an example, during the testing process, it is necessary to manually plug and power on each product one by one, resulting in low efficiency. There will also be a situation where the product slips due to being unable to hold it firmly during the operation. In order to improve the testing efficiency and safety, a jig is used to clamp and fix the center control instrument panel. However, the shapes of the center control instrument panels on different vehicle models are different, and most of the existing jigs have fixed structures. Although they can clamp and fix center control instrument panels of different sizes, they cannot be adjusted according to the shape of the center control instrument panel, and it is easy to have problems with loose clamping during the flipping and adjustment process. Content of the Utility Model

[0003] The purpose of the utility model is to provide a jig for power-on testing of automotive center control instrument panels to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A jig for power-on testing of automotive center control instrument panels, including a jig main body and a center control instrument panel. A testing component is fixedly installed on the back of the jig main body, and a clamping mechanism is fixedly installed on the jig main body.

[0005] The clamping mechanism includes a hollow rectangular frame and a fixed cylinder. The hollow rectangular frame and the fixed cylinder are connected through a communicating pipe. The fixed cylinder is fixedly installed on the jig main body. A piston is slidably arranged on the inner wall of the fixed cylinder. One side outer wall of the piston facing the center control instrument panel is fixedly installed with a contact rod. The contact rod movably penetrates the inner wall of the fixed cylinder. There are multiple fixed cylinders, and they are symmetrically distributed on four sides of the jig main body. An electromagnetic valve is arranged on the communicating pipe, and an air inlet pipe is connected to the left side of the hollow rectangular frame.

[0006] Further, the left end of the air inlet pipe is connected with a rotary joint. The left end port of the rotary joint is connected with a U-shaped pipe. The bottom end of the U-shaped pipe is connected with a circulating air pump.

[0007] Further, a bracket is fixedly installed at the bottom of the circulating air pump. A motor is fixedly installed on the right outer wall of the bracket. The output end of the motor is fixedly installed with a rotating shaft. The left end of the rotating shaft is fixedly installed with a connecting frame. The connecting frame is fixedly installed on the outer wall of the jig main body.

[0008] Furthermore, a plug plate is fixedly installed on the outer wall of the test component, and a joint is fixedly installed on the outer wall of the test component.

[0009] Furthermore, a groove is provided at one end of the resistance rod facing the central control instrument panel, and a spring is fixedly installed on the inner wall of the groove, a baffle is fixedly installed at the end of the spring facing outside the groove, and a rubber pad is fixedly installed at the end of the baffle away from the spring.

[0010] Furthermore, a pressure gauge is fixedly mounted on the outer wall of the hollow rectangular frame, and an air inlet end of the pressure gauge is connected to the interior of the hollow rectangular frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. High-pressure airflow is introduced into the hollow rectangular frame through the intake pipe and then enters the fixed cylinder through the connecting pipe. The airflow drives the piston, which in turn drives the resistance rod to move, causing it to press against the central instrument panel. Multiple resistance rods on the fixed cylinder press against the central instrument panel from different directions, securing the central instrument panel. The movement length of each resistance rod does not interfere with each other, allowing it to accommodate central instrument panels of different shapes.

[0013] 2. It is connected to the interior of the same hollow rectangular frame through multiple fixing tubes, so the force of multiple resistance rods pressing on the central control instrument panel is within a certain range. Compared with the clamping of elastic parts, there is no problem of excessive elasticity causing damage to the central control instrument panel and too little elastic force to cause inability to clamp.

[0019] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: an automobile central control instrument panel power-on test fixture, including a fixture main body 1 and a central control instrument panel 2. A test component 3 is fixedly installed on the back of the fixture main body 1, and a clamping mechanism 4 is fixedly installed on the fixture main body 1;

[0021] The clamping mechanism 4 includes a hollow rectangular frame 401 and a fixed cylinder 402. The hollow rectangular frame 401 and the fixed cylinder 402 are connected through a communication pipe 404. The fixed cylinder 402 is fixedly installed on the fixture main body 1. A piston 405 is slidably arranged on the inner wall of the fixed cylinder 402. One side outer wall of the piston 405 facing the central control instrument panel 2 is fixedly installed with a contact rod 406. The contact rod 406 movably penetrates the inner wall of the fixed cylinder 402. There are multiple fixed cylinders 402, and they are symmetrically distributed on the four sides of the fixture main body 1. An electromagnetic valve is arranged on the communication pipe 404. The left side of the hollow rectangular frame 401 is connected and provided with an air inlet pipe 403. High-pressure air flow is introduced into the hollow rectangular frame 401 through the air inlet pipe 403, and then enters the fixed cylinder 402 through the communication pipe 404. The air flow pushes the piston 405 to move, and then drives the contact rod 406 to move, so that the contact rod 406 presses on the central control instrument panel 2. The contact rods 406 on multiple fixed cylinders 402 press on the central control instrument panel 2 from different directions to fix the central control instrument panel 2. The moving lengths of each contact rod 406 do not interfere with each other, and can cope with central control instrument panels 2 of different shapes. And because the multiple fixed cylinders 402 are connected, the forces exerted by the multiple contact rods 406 on the central control instrument panel 2 are within a certain range. Compared with elastic clamping, there is no problem of excessive elasticity damaging the central control instrument panel 2 and too small elasticity being unable to clamp. An electromagnetic valve is arranged on the communication pipe 404 to control the opening and closing of the communication pipe 404, and is used to select the corresponding fixed cylinder 402 according to the shape and size of the central control instrument panel 2;

[0022] The left end of the air inlet pipe 403 is connected and provided with a rotary joint 12. The left end port of the rotary joint 12 is connected and provided with a U-shaped pipe 13. The bottom end of the U-shaped pipe 13 is connected and provided with a circulating air pump 14. The U-shaped pipe 13 and the hollow rectangular frame 401 are connected through the rotary joint 12, so that the air flow generated by the circulating air pump 14 can enter the hollow rectangular frame 401 from the U-shaped pipe 13, and the air flow in the hollow rectangular frame 401 can be extracted, thereby controlling the movement of the contact rod 406;

[0023] A bracket 15 is fixedly installed at the bottom of the circulating air pump 14. A motor 10 is fixedly installed on the outer wall of the right side of the bracket 15. The output end of the motor 10 is fixedly installed with a rotating shaft 11. The left end of the rotating shaft 11 is fixedly installed with a connecting frame 9. The connecting frame 9 is fixedly installed on the outer wall of the jig main body 1. By driving the rotating shaft 11 to rotate by the motor 10, the connecting frame 9 is driven to rotate. The rotation of the connecting frame 9 drives the jig main body 1 to rotate, adjusting the orientation of the jig main body 1, which is convenient for the user to conduct a power-on test on the central control instrument panel 2;

[0024] A plug board 301 is fixedly installed on the outer wall of the test component 3 for connecting the plug on the central control instrument panel 2. A connector 302 is fixedly installed on the outer wall of the test component 3 for inserting into the interface on the central control instrument panel 2;

[0025] A groove is formed at one end of the contact rod 406 facing the central control instrument panel 2, and a spring 6 is fixedly installed on the inner wall of the groove. One end of the spring 6 facing the outside of the groove is fixedly installed with a baffle 7. One end of the baffle 7 away from the spring 6 is fixedly installed with a rubber pad 8. When the contact rod 406 moves towards the central control instrument panel 2, since the air flow pushes the piston 405 to move at a relatively fast speed, in order to avoid the directly collision between the fast-moving contact rod 406 and the central control instrument panel 2, the spring 6, the baffle 7 and the rubber pad 8 are provided for buffering to avoid damaging the central control instrument panel 2;

[0026] A pressure gauge 5 is fixedly installed on the outer wall of the hollow rectangular frame 401. The air inlet end of the pressure gauge 5 is communicated with the inside of the hollow rectangular frame 401 for testing the air pressure inside the hollow rectangular frame 401, thereby avoiding excessive air pressure inside the hollow rectangular frame 401 and causing excessive force of the contact rod 406 pressing on the central control instrument panel 2.

[0027] Working principle: When in use, place the central control instrument panel 2 in the jig main body 1, turn on the circulating air pump 14 to introduce high-pressure air flow into the U-shaped tube 13. The air flow enters the hollow rectangular frame 401 from the rotary joint 12, and then enters the fixed cylinder 402 from the communicating pipe 404. The air flow pushes the piston 405 to move, thereby driving the contact rod 406 to move, so that the contact rod 406 presses on the central control instrument panel 2. The contact rods 406 on multiple fixed cylinders 402 press on the central control instrument panel 2 from different directions to fix the central control instrument panel 2. Connect the interface and plug on the central control instrument panel 2 with the connector 302 and the plug board 301 on the test component 3 for a power-on test. After the test is completed, turn on the circulating air pump 14 to suck out the air flow inside the hollow rectangular frame 401, so that the piston 405 drives the contact rod 406 to move away from the central control instrument panel 2, and then the central control instrument panel 2 can be taken out.

[0028] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
