Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame inspection tools, in particular to a front auxiliary vehicle frame assembly inspection tool. Background Art

[0002] The front subframe assembly is the front half of the subframe. The subframe can be regarded as the skeleton of the front and rear axles and is a component of the front and rear axles. The function of the subframe is to block vibration and noise and reduce their direct entry into the car. After the front subframe assembly is manufactured, the frame needs to be inspected by a check fixture. Common inspection contents include size inspection, appearance inspection, distortion inspection, etc. Among them, during the appearance inspection process, cracks, burrs, scratches, etc. will be inspected. The front subframe assembly is often wiped, and the burrs of the holes and slots are polished, which will cause a large amount of debris and dust to accumulate on the surface of the inspection fixture.

[0003] For example, a front subframe assembly inspection fixture with the authorization announcement number "CN219347802U" has dust suction mechanisms installed at both ends of the inspection platform. When the dust suction mechanisms are activated, the dust suction mechanisms move the dust on the top of the inspection platform body through the dust suction hood and the dust suction pipe to the collection bin, thereby achieving the effect of cleaning the dust on the surface of the inspection platform.

[0004] However, since the dust and debris in the middle of the test bench surface is at a certain distance from the dust hood, it is not easy to clean the middle of the test bench surface during actual use. Since the dust hood is fixed in position, the dust collection range is also limited, which is not conducive to efficient cleaning of dust and debris on the test bench surface.

[0005] Furthermore, when this type of test bench uses a clamp (similar to the extrusion plate in the public document) to clamp the front subframe assembly, it is necessary to manually carry the front subframe assembly between the two clamps in advance, and then clamp and fix the front subframe assembly with the clamp, which will result in a large amount of manpower investment in the process of testing the front subframe assembly. Utility Model Content

[0006] The utility model aims to provide a front subframe assembly inspection fixture to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Furthermore, an electric push rod 1 is inserted and fixed in the middle of the main body of the detection platform, a support plate is fixed to the output end of the electric push rod 1, and a rectangular notch for accommodating the support plate is opened on the top surface of the main body of the detection platform.

[0011] Furthermore, a carrier plate is fixed to one end of the detection platform body, a motor 1 is fixed to the top surface of the carrier plate, and an output end of the motor 1 is fixedly connected to a bidirectional lead screw.

[0012] Furthermore, a second motor is fixed on the top surface of the carrier plate, an output end of the second motor is fixedly connected to a one-way screw rod at a corresponding position, and both ends of the one-way screw rod are rotatably connected to a connecting seat fixedly connected to a main body of the detection platform.

[0013] Furthermore, a synchronous pulley is fixed to one end of the one-way screw rod, a synchronous belt is connected between the two synchronous pulleys, and sliding grooves are provided on both sides of the detection platform body, which are slidably connected to the L-shaped blocks at corresponding positions.

[0014] Furthermore, one end of the square tube 1 is connected and fixed with a rubber tube, the end of the rubber tube facing away from the square tube 1 is sealed, the bottom surface of the rubber tube is provided with a dust suction mesh hole 2, and there is a gap between the rubber tube, the square tube 1 and the square tube 2 and the surface of the test bench body.

[0015] Furthermore, a suction end of the vacuum cleaner is connected and fixed with a vacuum hose, and the square tube 1 and the square tube 2 are respectively connected and fixed with the vacuum hoses at corresponding positions.

[0017] 1. The one-way screw at the output end of the motor 2 is rotated, and the other one-way screw is rotated synchronously under the transmission action of the synchronous belt, so that the L-shaped block screwed with the one-way screw can move along the surface of the main body of the test bench, and then the square tube 1 and the square tube 2 can move along the surface of the main body of the test bench, and the vacuum cleaner draws air into the vacuum hose, and the vacuum hose draws air into the inside of the square tube 1 and the square tube 2, so that the dust and debris on the surface of the main body of the test bench can be sucked into the vacuum cleaner through the vacuum mesh 1 on the bottom surface of the square tube 1 and the square tube 2, and the output end of the motor 2 can be rotated in the opposite direction, so that the L-shaped block on the one-way screw drives the square tube 1 and the square tube 2 to move in the opposite direction on the top of the main body of the test bench, so as to facilitate reciprocating and all-round cleaning of the main body of the test bench.

[0018] 2. A rubber tube is connected and fixed at one end of the square tube, and a dust suction mesh hole 2 is opened on the bottom surface of the rubber tube. The dust suction mesh hole 2 can also clean the main body of the test bench when the rubber tube moves with the square tube. Since the rubber tube can be bent and deformed, when the rubber tube passes through the moving column, the rubber tube bends to facilitate passing through the moving column, and the rubber tube can vacuum and clean the area between the two moving columns. An electric push rod 1 is fixed in the middle of the main body of the test bench. The electric push rod 1 moves up with the support plate so that the front sub-frame assembly can be automatically moved to the position between the two clamping plates and is not clamped and fixed, eliminating the need to manually move the front sub-frame assembly to the position between the two clamping plates, thereby saving manpower.

[0028] Specifically, the two-way screw rod 200 is rotated to make the two moving columns 210 move with the two clamping plates 310 towards each other, and then the electric push rod 2 300 moves with the clamping plates 310 in the direction of the front sub-frame, so that the front sub-frame is clamped and fixed for inspection, and the one-way screw rod 410 moves with the L-shaped block 420 on the inspection table body 100, so that the dust suction mesh 1 on the bottom surface of the square tube 1 430 and the square tube 2 440 automatically sucks debris and dust on the surface of the inspection table body 100, thereby achieving all-round cleaning of the inspection table body 100.
