Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically a positioning mechanism for automotive parts access testing. Background Technology

[0002] Automotive parts refer to components of a car. After production, they need to undergo a series of tests to meet sales standards. Among these tests, the accessibility test of automotive pipelines is to check whether there are blockages or leaks inside the car's pipelines (such as air pipes or water pipes). During this process, a positioning mechanism is used to fix and clamp the pipelines to facilitate subsequent testing operations.

[0003] In the prior art, Chinese patent application number CN202120534592.0 discloses a clamping and positioning fixture for an automotive component shaft rod, including a base, a positioning seat set according to the standard dimensions of the shaft rod assembly, a push cylinder, a pressing cylinder, a pressing block, a positioning bracket, a positioning block, a standard locking block, and a go / no-go gauge. The upper end face of the positioning seat has a positioning groove for positioning the shaft rod, and a positioning bracket is set at the front end. The push cylinder is set at the front end of the positioning seat, and the push rod of the push cylinder is directly opposite the flared opening at the front end of the shaft rod. After the fixture positions the shaft rod with the help of the positioning seat, it is pushed by the front push cylinder and pressed by the upper pressing block to clamp it. Combined with the standard locking block as a go / no-go gauge, it detects whether the outer diameter of the flared opening at the front end of the shaft rod is qualified.

[0004] Based on the above information, it can be seen that in the prior art, the positioning mechanism achieves the purpose of clamping and fixing before testing auto parts. However, in actual use, the pipes in the car (mainly referring to rigid metal or plastic pipes) are prone to damage due to uneven force on both sides when they are removed after testing, because the pipes are long. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning mechanism for the inspection of automotive parts access channels, so as to solve the problem of damage caused by uneven force during disassembly mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for detecting automotive parts access channels, comprising a support base placed horizontally on a table, a placement platform fixedly installed at the middle position of the upper surface of the support base, water tanks fixedly installed at the left and right ends of the upper surface of the support base, and a docking mechanism provided on the side of the water tanks; a clamping block provided above the placement platform, and the automotive pipeline to be detected is clamped inside the clamping block; a main top plate and an auxiliary top plate are provided above the placement platform, and a hydraulically driven lifting mechanism is provided between the main top plate and the placement platform, using the main top plate and the auxiliary top plate to lift and disassemble the automotive pipeline.

[0007] Preferably, the docking mechanism includes a connector fixedly installed on the side of the water tank, and a water pressure sensor is fixedly installed inside the connector. The connector is connected to the vehicle pipeline via a connecting hose.

[0008] Preferably, an adjusting slider that moves synchronously with the lower surface of the clamping block is fixedly installed, and the adjusting slider and the adjusting groove formed on the upper surface of the placement platform form a sliding structure.

[0009] Preferably, the cross-section of the adjusting slider is convex, and the lower surface of the clamping block is fixedly installed with the magnetic block adsorbed on the upper surface of the placement platform.

[0010] Preferably, the lifting mechanism includes a receiving groove located at the middle of the upper surface of the placement platform, and the main top plate and the receiving groove form an up-and-down sliding structure.

[0011] Preferably, the receiving trough is connected to the water storage tank through a conveying pipe on the side of the placement platform, and the main top plate is fixedly connected to the auxiliary top plate through a connecting rod.

[0012] Preferably, a sealing ring is fixedly installed on the side of the main top plate to seal the inner wall of the receiving groove, and an adsorption sponge for adsorbing impurities is fixedly installed on the lower surface of the main top plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the positioning mechanism for the automotive parts access detection adopts a novel structural design, the specific details of which are as follows:

[0014] 1. Fix the automotive pipeline (rigid pipeline) to be tested above the placement platform using clamping blocks. Then, inject liquid from the water tank into the automotive pipeline through the connecting hose. With the help of the water pressure sensor, the purpose of detecting the passage is achieved. After the test is completed, the liquid is injected into the receiving tank through the delivery pipe. Under the action of water pressure, the main top plate is lifted up. Finally, the main top plate and the auxiliary top plate are used to lift the automotive pipeline to achieve the purpose of disassembly. Since the main top plate and the auxiliary top plate are evenly distributed, the force is evenly distributed when lifting, reducing damage.

[0015] Furthermore, an adjustment slider is provided below the clamping block. The adjustment slider can slide in the adjustment groove opened above the placement platform, thereby changing the position of the clamping block (after changing the position, the adsorption effect of the magnetic block is used to achieve the purpose of fixation), so that the device can adapt to the inspection operation of automotive pipelines of different shapes.

[0016] 2. A sealing ring is installed on the side of the main top plate to ensure a tight seal with the inside of the receiving groove, thus ensuring that hydraulic pressure can lift the main top plate. An absorbent sponge is installed on the lower surface of the main top plate. After the liquid flows into the receiving groove, the absorbent sponge can absorb some of the impurities (which come from the inner wall of the car's pipeline), thereby reducing the possibility of subsequent blockage.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example 1: Please refer to Figures 1-2 In order to achieve the purpose of pipeline testing, this embodiment provides the following technical solution, which specifically discloses: a support base 1 placed horizontally on a table, a placement platform 2 fixedly installed at the middle position of the upper surface of the support base 1, a water storage tank 3 fixedly installed at the left and right ends of the upper surface of the support base 1, and a docking mechanism provided on the side of the water storage tank 3, a clamping block 4 provided above the placement platform 2, and the vehicle pipeline 5 to be tested is clamped inside the clamping block 4; the docking mechanism includes a connector 6 fixedly installed on the side of the water storage tank 3, and a water pressure sensor 8 fixedly installed inside the connector 6, and the connector 6 is connected to the vehicle pipeline 5 through a connecting hose 7.

[0026] When using the device, first clamp the car pipe 5 to be tested inside the clamping block 4, so that the car pipe 5 is fixed above the placement platform 2. Then take out the connecting hose 7, connect one end to the car pipe 5, and connect the other end to the connector 6. Then turn on the water pump structure inside the water tank 3 so that the liquid is delivered to the car pipe 5 through the connecting hose 7. At this time, use the values ​​detected by the water pressure sensors 8 in the connectors 6 at both ends to judge the internal continuity of the car pipe 5 (if the difference between the water pressure sensors 8 at both ends is within the required range, it means that it is completely conductive; if it is outside the range, it means that there is a problem).

[0027] Example 2: Please refer to Figures 3-4 In order to achieve the purpose of adapting to the detection of pipelines of different shapes, this embodiment provides the following technical solution, which specifically discloses: an adjusting slider 9 that moves synchronously with the lower surface of the clamping block 4 is fixedly installed, and the adjusting slider 9 and the adjusting groove 10 opened on the upper surface of the placement platform 2 form a sliding structure. The cross-section of the adjusting slider 9 is a "convex" shaped structure, and an adsorption magnetic block 11 that is adsorbed to the upper surface of the placement platform 2 is fixedly installed on the lower surface of the clamping block 4.

[0028] When positioning automotive pipes 5 of different shapes, the corresponding clamping block 4 is first slid back and forth. During this process, the adjusting slider 9 below the clamping block 4 slides accordingly inside the adjusting groove 10. After moving to a fixed position, the clamping block 4 is fixed by the adsorption effect between the magnetic block 11 below the clamping block 4 and the placement platform 2.

[0029] Example 3: Please refer to Figures 5-6 In order to achieve the purpose of lifting the pipeline under uniform force, this embodiment provides the following technical solution, which specifically discloses: a main top plate 12 and an auxiliary top plate 14 are provided above the placement platform 2, and a hydraulically driven lifting mechanism is provided between the main top plate 12 and the placement platform 2. The main top plate 12 and the auxiliary top plate 14 are used to lift and disassemble the car pipeline 5. The lifting mechanism includes a receiving groove 15 opened in the middle of the upper surface of the placement platform 2, and the main top plate 12 and the receiving groove 15 form an up-and-down sliding structure. The receiving groove 15 is connected to the water storage tank 3 through the conveying pipe 16 on the side of the placement platform 2, and the main top plate 12 is fixedly connected to the auxiliary top plate 14 through the connecting rod 13. A sealing ring 17 that seals the inner wall of the receiving groove 15 is fixedly installed on the side of the main top plate 12, and an adsorption sponge 18 for adsorbing impurities is fixedly installed on the lower surface of the main top plate 12.

[0030] After the test is completed, the water pump structure inside the water tank 3 is used to transport the liquid through the delivery pipe 16 to the inside of the container tank 15. At this time, the pressure inside the container tank 15 increases, which pushes the main top plate 12 upward (the sealing ring 17 on the side of the main top plate 12 is in close contact with the inner wall of the container tank 15). During the upward movement of the main top plate 12, the auxiliary top plate 14 is driven to move upward synchronously through the connecting rod 13, so that the main top plate 12 and the auxiliary top plate 14 cooperate to lift the car pipeline 5. During this process, the car pipeline 5 is subjected to uniform force, reducing the risk of damage. After the liquid enters the inside of the container tank 15, the adsorption sponge 18 under the main top plate 12 adsorbs some of the impurities, achieving the purpose of purification and avoiding subsequent blockage.
