Abstract

The present invention discloses a detection device for an automobile front steering knuckle system with an irregular structure, which relates to the technical field of automobile steering detection. It includes a mounting plate, and two clamping and sealing components that are respectively slidably connected to both ends of the mounting plate. A support component is fixedly installed on the mounting plate. By starting the driving source, the two clamping and sealing components are driven to move. Through the movement of the two clamping and sealing components, both ends of the oil return pipes with different lengths can be clamped and sealed, so that the device can be used without adjusting according to the length of the oil return pipe. At the same time, when the clamping and sealing components move, they can squeeze the oil return pipe through the contact of the first cross plate with the oil return pipe, so that the oil return pipe is flattened, preventing the bending of the oil return pipe from affecting the detection of its airtightness.

A fixing plate 36 is provided on the third housing 31. The ratchet group 34 enables the clamping movement of the clamping and sealing assembly 2 to be unaffected by the lengths of the first wire 251, the third wire 257, and the fourth wire 258.

[0041] Preferably, the clamping and sealing assembly 2 further includes a reset unit 25. The reset unit 25 includes a first wire 251 with one end fixedly connected to the sealing gasket 246. The other end of the first wire 251 is connected to a wire reel 35. Through the first wire 251, the movement of the sealing gasket 246 can be reset for the next sealing use.

[0042] Preferably, the reset unit 25 further includes a second wire 252 with one end fixedly connected to the first cross plate 235. The other end of the second wire 252 is connected to a winding member 253. The winding member 253 is rotatably connected within the first housing 21. A gear 254 is fixedly connected to the winding member 253. The gear 254 meshes with a rack 255. The rack 255 is slidably connected within the first housing 21. The provision of the second wire 252 enables the first cross plate 235 and the second cross plate 238 to be reset after use for the next sealing use.

[0043] Preferably, the reset unit 25 further includes a sliding plate 256 slidably connected within the first housing 21. The sliding plate 256 is fixedly connected to one end of a third wire 257. The other end of the third wire 257 is connected to a wire reel 35. The third wire 257 can drive the sliding plate 256 to be reset.

[0044] Preferably, the reset unit 25 further includes a fourth wire 258 with one end fixedly connected to the connecting member 222. The other end of the fourth wire 258 is connected to a wire reel 35. The winding of the fourth wire 258 can reset the connecting member 222, open the clamping, and enable the next clamping operation.

[0045] Preferably, the clamping and sealing assembly 2 further includes a pulling unit 26. The pulling unit 26 includes two torsion springs 261 respectively fixedly connected to both ends of the mounting plate 1. The output ends of the two torsion springs 261 are respectively connected to one end of two fifth wires 262 in one-to-one correspondence. The other ends of the two fifth wires 262 are respectively connected to two first housings 21. By arranging the pulling unit 26, the two clamping and sealing assemblies 2 can be driven to move to clamp and seal oil return pipes of different sizes.

[0046] Working principle: Place the middle part of the oil return pipe on the support plate 32, and then start the drive source 33 to drive the inner ring of the ratchet to rotate, so that the rotation of the outer ring of the ratchet is no longer restricted. At this time, under the pulling of the two torsion springs 261, the two fifth wires 262 are wound up, so that the two first housings 21 move away from each other, causing the fifth spring telescopic member 237 to release and drive the second cross plate 238 to move, driving the second wire 252 to be released, causing the winding member 253 to rotate, driving the gear 254 to rotate, causing the rack 255 to slide outside the first housing 21. The movement of the second cross plate 238 drives the long rod 239 to move, causing the fourth spring telescopic member 234 to be gradually released, driving the first cross plate 235 to move. When the fourth spring telescopic rod is completely released, the bottom of the first cross plate 235 no longer contacts the first housing 21, causing the third spring telescopic member 233 to release, driving the fourth spring member to move downward, causing the first cross plate 235 to move downward and contact the top of the oil return pipe. The first cross plate 235 continuously moves until it no longer contacts the oil return pipe. At this time, the oil return pipe no longer blocks the downward movement of the first cross plate 235. The first cross plate 235 moves downward and contacts the arc surfaces of the two trigger members 232, causing the two trigger members 232 to move, driving the two second spring telescopic members 231 to expand and contract, causing the connecting member 222 to no longer be limited by the trigger member 232, causing several first spring telescopic members 221 to be released, driving the clamping members 223 to move upward to squeeze the bottom of the oil return pipe, and causing the top of the oil return pipe to abut against the second cross plate 238, clamping the oil return pipe. At the same time, the first cross plate 235 continues to move downward and contacts the pressing plate 243 and drives the pressing plate 243 to move downward, causing the sixth spring telescopic member 242 to contract, driving the seventh spring telescopic member 244 to move downward, causing the latch 247 to no longer be limited, causing the eighth spring telescopic member 245 to be released, driving the sealing gasket 246 to move, causing the sealing gasket 246 to squeeze the clamped end of the oil return pipe, clamping and sealing both ends of the oil return pipe. Then, the entire device can be moved downward into the water for airtightness detection;

[0047] When the detection is completed, the driving source 33 is started to reverse, driving the ratchet wheel to rotate, so that the plurality of winding reels 35 rotate, driving the first wire 251, the third wire 257 and the fourth wire 258 to be wound up, and the winding of the first wire 251 drives the sealing gasket 246 to move, so that the seal of the oil return pipe is released, so that the eighth spring telescopic member 245 contracts, driving the clamping block 247 to move to contact the arc surface of the seventh spring telescopic member 244, so that the seventh spring telescopic member 244 contracts, and when the clamping block 247 moves to no longer contact the seventh spring telescopic member 244, the seventh spring telescopic member 244 is released, so that the seventh spring telescopic member 244 resumes the limiting function of the clamping block 247;

[0048] The winding of the third wire 257 drives the sliding plate 256 to move upward, and the upward movement of the sliding plate 256 drives the first horizontal plate 235 to move upward, so that the short rod 236 moves upward to fit with the long rod 239;

[0049] The winding of the fourth wire 258 drives the connecting member 222 to move downward, so that the clamping member 223 moves downward, so that the clamping of the oil return pipe is released, and when the connecting member 222 moves downward, it contacts the arc surfaces of the two triggering members 232, so that the two triggering members 232 contract, so that the connecting member 222 moves downward to below the two triggering members 232, so that the two triggering members 232 resume the limiting function of the connecting member 222;

[0050] At this time, the oil return pipe can be taken out, and then the continuous winding of the first wire 251, the third wire 257 and the fourth wire 258 drives the two first housings 21 to be close to each other, so that the two clamping seal assemblies 2 are close to each other, and drives the two racks 255 to contact the fixed plate 36, so that the two racks 255 slide in the first housing 21, drives the gear 254 to rotate, so that the winding member 253 rotates, drives the second wire 252 to reel, so that the second transverse plate 238 moves, drives the fifth spring expansion member 237 to shrink, so that the long rod 239 moves, drives the short rod 236 to move, so that the first transverse plate 235 moves, drives the fourth spring expansion member 234 to shrink, so that the first transverse plate 235 and the second transverse plate 238 are reset, so that the two sealing clamping assemblies are reset, and at the same time, the reset of the two first housings 21 drives the two fifth wires 262 to move, so that the two torsion springs 261 store force;

[0051] In the present invention, an inner diameter detection component module is further included on the base for detecting the inner diameter of the steering knuckle bearing hole 7. The inner diameter detection component includes a telescopic rod 4. The telescopic rod 4 is arranged on the base (not shown in the figure), and a plurality of pressure sensors are arranged at the telescopic end of the telescopic rod 4. The size of the telescopic rod 4 is smaller than the size of the bearing hole. In the present invention, by arranging the array pressure sensors 5, and then driving the array of pressure sensors to move inside the inner hole of the bearing of the steering knuckle 6 through the telescopic rod 4, that is, the detection of the hole size can be realized. When the size is smaller or larger, the pressure sensor 5 will be triggered to alarm, so that the detection of the qualified inner wall aperture of the bearing hole 7 of the steering knuckle 6 can be realized, and the accuracy of the inner hole of the bearing can be improved.

[0052] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
