[0001] The invention relates to the technical field of automobile brakes, in particular to an intelligent air tightness detection device for a vehicle-mounted brake pump. Background Art

[0002] The automobile brake master cylinder is also called the brake master oil (gas). Its main function is to push the brake fluid (or gas) to each brake cylinder to push the piston.

[0003] Most of the currently available intelligent air tightness detection devices for vehicle-mounted brake pumps fix the vehicle-mounted brake pumps through hydraulic devices, and inject air pressure into the vehicle-mounted brake pumps for air tightness detection. However, during the placement process of the vehicle-mounted brake pumps, most of them fix the vehicle-mounted brake pumps through support frames and oil cylinders. However, during the air tightness detection process, the single support frame and oil cylinder are limited to clamping and fixing the top of the vehicle-mounted brake pump, and the fixation of the vehicle-mounted brake pump surface around is not comprehensive enough. Therefore, when the air pump inflates the vehicle-mounted brake pump, there will inevitably be shaking problems, which may cause leakage of the inflation inside the vehicle-mounted brake pump, and thus inaccurate air tightness detection of the vehicle-mounted brake pump.

[0004] Therefore, there is an urgent need for an intelligent detection device for air tightness of a vehicle-mounted brake pump to solve the problems of the prior art. Summary of the invention

When the driving motor is running, the outer rotating sleeve rod is effectively lifted and slid on the surface of the slide groove through the slider, so that the rotating inner rod and the lower surface of the outer rotating sleeve rod are sealed and squeezed, and the generated air can be discharged through the telescopic tube. Since the lower surface of the telescopic tube corresponds to the surface of the vehicle-mounted brake pump to be detected, the air can be directly introduced into the vehicle-mounted brake pump through the telescopic tube, and the internal air pressure of the vehicle-mounted brake pump is monitored in real time through the provided pressure gauge, so that the air tightness detection of the vehicle-mounted brake pump is convenient and simple.

[0016] 2. In the intelligent detection device for air tightness of vehicle-mounted brake pump, the vehicle-mounted brake pump that needs to be tested for air tightness is placed on the surface of the gasket, and the provided card slot can limit the bottom surface of the vehicle-mounted brake pump. After the provided telescopic tube corresponds to the upper surface of the vehicle-mounted brake pump, an extrusion force is generated. Under the action of the extrusion force, since a compression spring is connected to one side of the lower surface of the connecting plate, under the action of the compression spring, the outer surface of the connecting plate is lifted up all around, and the lower pressing block is squeezed synchronously, so that the lower pressing block moves horizontally upward, and the positioning block and the limit block are effectively connected and corresponded through the positioning hole. Under the stretching action of the telescopic spring 1 and the telescopic spring 2, the telescopic plate can be pushed out to one side of the upper pressing block and contact with the bottom of the outer surface of the vehicle-mounted brake pump all around, thereby playing a contact and tightening role.

[0017] 3. In the vehicle-mounted brake pump air tightness intelligent detection device, the adjustment plate is also tilted synchronously by tilting the connecting plate.

[0018] 4. In the intelligent air tightness detection device for the vehicle-mounted brake pump, at the same time, the chassis can be lowered synchronously when the telescopic tube descends on the lower surface of the sealing tank, so that the lower surface of the docking block can be in contact with the surface of the adjustment plate, which can play a card-limiting effect on the adjustment plate. In the process of air tightness detection of the vehicle-mounted brake pump, it plays a clamping and tightening role to avoid shaking or loosening of the vehicle-mounted brake pump.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Example

[0022] See also Figure 1 - Fig.10 As shown, the purpose of this embodiment is to provide an intelligent detection device for air tightness of a vehicle-mounted brake pump, including a test group 200, a placement group 300 and a clamping group 400, the lower surface of the test group 200 is fixedly installed with a mounting group 100, the lower surface of the test group 200 corresponds to the position of the upper surface of the placement group 300, the lower surface of the test group 200 is connected to an outer rotating sleeve rod 211, the center position of the lower surface of the clamping group 400 is connected to a gasket 401, and the test group 200 is connected to the outer rotating sleeve rod 211 through the outer rotating sleeve rod 211. The surface of the gasket 401 is raised and lowered in contact, corresponding to the lifting and extrusion of the surface of the clamping group 400. The bottom of the lower surface of the outer rotating sleeve 211 is connected to a telescopic tube 205. The outer surface of the gasket 401 is connected to a connecting plate 402. The telescopic tube 205 moves up and down on the upper surface of the clamping group 400 through the outer rotating sleeve 211. After the telescopic tube 205 is pressed and sleeved on the upper surface of the vehicle-mounted brake pump, the lower surface of the vehicle-mounted brake pump squeezes and deforms the connecting plate 402, so that the lower surface of the connecting plate 402 is contracted and clamped. Furthermore, after the vehicle-mounted brake pump that needs to be tested for air tightness is clamped on the surface of the gasket 401, since the positions of the clamping group 400 and the test group 200 correspond, after the test group 200 is run, it corresponds to the upper surface of the vehicle-mounted brake pump and squeezes the vehicle-mounted brake pump. The generated squeezing force can cause the clamping group 400 to deform, and the upper and lower ends of the outer surface of the vehicle-mounted brake pump can be clamped and fixed, ensuring that the vehicle-mounted brake pump always remains in a stable state during the air tightness test process.

[0023] Considering the need to realize the testing function of the test group 200, in this embodiment, the test group 200 includes a support frame 201, a driving motor 202 is installed at the center of the upper surface of the support frame 201, a sealing tank 203 is connected to the lower surface of the driving motor 202, a rotating inner rod 209 is rotatably connected to the top of the inner side of the sealing tank 203, a sliding groove 210 is provided around the outer surface of the rotating inner rod 209, a sliding block 212 is slidably connected to the outer surface of the sliding groove 210, and the surface of the sliding block 212 is connected to the outer rotating sleeve rod 211. A telescopic tube 205 is connected to the center of the lower surface of the sleeve rod 211, a barometer 208 is installed on the left side of the outer surface of the telescopic tube 205, the lower surface of the telescopic tube 205 is connected to the chassis 204, buffer springs 206 are connected around the lower surface of the chassis 204, and the lower surface of the buffer spring 206 is connected to a docking block 207. A through hole is opened at the center of the lower surface of the sealing tank 203, and the through hole is correspondingly sleeved with the telescopic tube 205, and the telescopic tube 205 is rotated and raised and lowered by rotating the sleeve rod 211 on the outer surface of the rotating inner rod 209. Further, the driving motor 202 is started to drive the rotating inner rod 209 to rotate. Under the action of the slide groove 210, the slider 212 slides, and through the spiral slide groove 210, the outer rotating sleeve rod 211 is effectively allowed to move up and down on the outer surface of the rotating inner rod 209. The outer rotating sleeve rod 211 and the lower surface of the rotating inner rod 209 are hollow. During the lifting and lowering movement, extrusion is generated, and the air generated during the extrusion process can be led out through the telescopic tube 205. After the lower surface of the test group 200 corresponds to the position of the vehicle-mounted brake pump clamped by the surface of the clamping group 400, the telescopic tube 205 telescopes downward and is correspondingly connected to the upper surface of the vehicle-mounted brake pump. The air can be transmitted to the inside of the vehicle-mounted brake pump through the telescopic tube 205, and the internal air pressure of the vehicle-mounted brake pump can be monitored in real time through the barometer 208; The improvement lies in that: through the provision of a spiral groove 210, the outer rotating sleeve rod 211 can make a lifting and reciprocating motion on the outer surface of the rotating inner rod 209, and can reciprocately squeeze the bottom of the rotating inner rod 209, similar to the movement of a piston, and the air generated by the squeezing is transported through the telescopic tube 205, and the telescopic tube 205 is correspondingly sleeved on the upper surface of the vehicle-mounted brake pump to introduce the air into the interior of the vehicle-mounted brake pump.

[0024] Considering the need to realize the clamping effect of the clamping group 400, in this embodiment, the clamping group 400 includes a gasket 401, and the outer surface of the gasket 401 is movably connected with a connecting plate 402 around it. A card slot 403 is opened at the center of the surface of the connecting plate 402. A lower pressing block 406 is installed on one side of the surface of the card slot 403. A positioning block 407 is installed on the right side of the upper surface of the lower pressing block 406. A telescopic spring 408 is connected to the left side of the surface of the positioning block 407. An upper pressing block 409 is installed on the right side of the upper surface of the lower pressing block 406. A telescopic spring 408 is connected to the left side of the lower surface of the upper pressing block 409. Spring 2 412, the left side of the surface of telescopic spring 2 412 is connected to the limit block 410, the center position of the lower surface of the limit block 410 is provided with a positioning hole 411, the left side of the surface of the limit block 410 is connected to the telescopic plate 413, one side of the surface of the connecting plate 402 is connected to the adjusting plate 404, the center position of the upper surface of the adjusting plate 404 is provided with a slide rail 405, one side of the lower surface of the connecting plate 402 is connected to the compression spring, and the connecting plate 402 is adjusted in angle around the surface of the gasket 401 through the compression spring, and drives the upper pressing block 409 and the adjusting plate 404 to adjust their angles synchronously; Furthermore, the vehicle-mounted brake pump that needs to be tested for air tightness is placed on the surface of the gasket 401. The provided card groove 403 can limit the bottom surface of the vehicle-mounted brake pump. After the provided telescopic tube 205 corresponds to the upper surface of the vehicle-mounted brake pump, an extrusion force is generated. Under the action of the extrusion force, since a compression spring is connected to one side of the lower surface of the connecting plate 402, under the action of the compression spring, the outer surface of the connecting plate 402 is lifted all around, and the lower pressing block 406 is squeezed synchronously, so that the lower pressing block 406 moves horizontally upward, effectively positioning the positioning block 407 and the limiting block 410 through The positioning holes 411 are connected in a corresponding manner. Under the stretching action of the telescopic spring 1 408 and the telescopic spring 2 412, the telescopic plate 413 can be pushed out to the side of the upper pressing block 409 to contact the bottom of the outer surface of the vehicle-mounted brake pump around, thereby playing a contact and fastening role. At the same time, the adjustment plate 404 is also tilted by the connecting plate 402, and is tilted synchronously. Under the action of the slide rail 405, the clamping plate 303 can slide on the surface of the slide rail 405 toward the surface position of the gasket 401, so that the upper surface of the clamping plate 303 contacts the top of the outer surface of the vehicle-mounted brake pump around, thereby further playing a contact and fastening role. After the telescopic tube 205 is connected to the upper surface of the vehicle-mounted brake pump and pressure is generated, under the action of pressure, the lower surface of the vehicle-mounted brake pump squeezes the gasket 401, causing the connecting plate 402 to deform. Under the action of the compression spring, one side of the connecting plate 402 is lifted, and under the docking of the positioning block 407 and the limit block 410, one side of the upper pressing block 409 is effectively lifted, allowing the telescopic plate 413 to extend from one end of the upper pressing block 409 and contact the lower surface of the vehicle-mounted brake pump around, which can play a role in tightening the lower surface of the vehicle-mounted brake pump around. On the contrary, after the telescopic tube 205 is separated from the surface of the vehicle-mounted brake pump, the telescopic plate 413 rebounds and resets, which is convenient for the staff to take the vehicle-mounted brake pump, and the operation is convenient and simple. The improvement lies in that: the vehicle-mounted brake pump is clamped on the upper surface of the gasket 401, and the air pressure is transmitted to the vehicle-mounted brake pump and squeezed. The lower pressure block 406 is lifted to one side after deformation, and is clamped with the limit block 410 correspondingly through the positioning block 407, synchronously driving the upper pressure block 409 to be lifted to one side, and under the synchronous stretching effect of the telescopic spring 1 408 and the telescopic spring 2 412, the telescopic plate 413 is extended from one side of the upper pressure block 409, and contacts with the lower surface of the vehicle-mounted brake pump on all sides, thereby achieving the effect of tightening and clamping.

[0025] Considering the need to realize the placement function of the placement group 300, in this embodiment, the placement group 300 includes a fixed plate 301, a placement disc 302 is installed on the upper surface of the fixed plate 301, and a clamping plate 303 is movably installed around the inner periphery of the placement disc 302. There are four clamping plates 303 in total, and the four clamping plates 303 are symmetrically distributed around the inner wall of the placement disc 302, and the upper surfaces of the four clamping plates 303 correspond to the positions of the docking blocks 207; Furthermore, the adjustment plate 404 is also tilted synchronously by the tilting of the connecting plate 402, and the lower surface of the clamping plate 303 corresponds to the set slide rail 405. Under the action of the slide rail 405, the clamping plate 303 can slide on the surface of the slide rail 405 toward the surface of the gasket 401, so that the upper surface of the clamping plate 303 contacts the top of the outer surface of the vehicle brake pump, further playing the role of contact and tightening; The improvement is that one side of the adjustment plate 404 is connected to the connecting plate 402. Under the action of the compression spring, the connecting plate 402 tilts to one side, which can synchronously tilt the adjustment plate 404 to a certain angle. Since the lower surface of the clamping plate 303 is connected to the slide rail 405, the clamping plate 303 can slide on the surface of the slide rail 405 after the adjustment plate 404 tilts, so that one side of the upper surface of the clamping plate 303 is effectively contacted and clamped with the upper surface of the vehicle-mounted brake pump, and has a certain stability. At the same time, when the lower surface of the sealing tank 203 is lowered, the chassis 204 can be lowered synchronously, so that the lower surface of the docking block 207 can be in contact with the surface of the adjustment plate 404, which can play a role of clamping and limiting the adjustment plate 404. During the air tightness detection process of the vehicle-mounted brake pump, it plays a role of clamping and tightening, avoiding the problem of shaking or loosening of the vehicle-mounted brake pump. Considering the need to realize the installation function of the installation group 100, in this embodiment, the installation group 100 includes a water tank 101, and a display screen 102 is arranged at the center of the surface of the water tank 101. The display screen 102 is electrically connected to the telescopic tube 205 and the barometer 208; The improvement lies in that the staff debugs the display screen 102 and can adjust the rotation frequency of the drive motor 202 to adjust the rotation amplitude between the outer rotating sleeve rod 211 and the rotating inner rod 209, and transmits the air generated by the lifting and squeezing of the outer rotating sleeve rod 211 and the rotating inner rod 209 to the inside of the vehicle-mounted brake pump through the telescopic tube 205 to perform an air tightness test on the vehicle-mounted brake pump.

[0026] In summary, the working principle of the present invention is as follows: the vehicle-mounted brake pump that needs to be tested for air tightness is clamped on the surface of the gasket 401 and corresponds to the opened clamping slot 403. The display screen 102 is debugged by the staff, and the rotation frequency of the driving motor 202 is adjusted. When the driving motor 202 is running, the outer rotating sleeve rod 211 is effectively lifted and slid on the surface of the slide groove 210 through the slider 212. Since the lower surfaces of the outer rotating sleeve rod 211 and the rotating inner rod 209 are hollow, a sealed space can be generated on the lower surfaces of the rotating inner rod 209 and the outer rotating sleeve rod 211, and the outer rotating sleeve rod 211 and the rotating inner rod 209 are connected to each other. The rod 209 moves to squeeze, and the generated air can be exported through the telescopic tube 205. Since the lower surface of the telescopic tube 205 corresponds to the surface of the vehicle-mounted brake pump that needs to be tested, the air can be directly introduced into the vehicle-mounted brake pump through the telescopic tube 205, and the internal air pressure of the vehicle-mounted brake pump can be monitored in real time through the provided pressure gauge 208, so that the air tightness detection of the vehicle-mounted brake pump is convenient and simple. At the same time, after the telescopic tube 205 is sleeved with the vehicle-mounted brake pump, pressure will be generated. Under the effect of squeezing, since a compression spring is connected to one side of the lower surface of the connecting plate 402, the outer surface of the connecting plate 402 is lifted around by the compression spring. The lower pressing block 406 is lifted up, and the lower pressing block 406 is squeezed synchronously, so that the other side of the lower pressing block 406 is lifted up, and the positioning block 407 is effectively connected and matched with the limit block 410 through the positioning hole 411. Under the stretching action of the telescopic spring 1 408 and the telescopic spring 2 412, the telescopic plate 413 can be pushed out to one side of the upper pressing block 409, and contact with the bottom of the outer surface of the vehicle-mounted brake pump around, so as to play a contact and tightening role. At the same time, the adjusting plate 404 is also tilted down by the connecting plate 402, and is tilted synchronously. Under the action of the slide rail 405, the clamping plate 303 can slide on the surface of the slide rail 405 toward the surface of the gasket 401, so that the upper surface of the clamping plate 303 is aligned with the upper surface of the The top of the outer surface of the vehicle-mounted brake pump is in contact all around, which further plays a role of contact and tightening, and when the telescopic tube 205 descends as the lower surface of the sealing tank 203, the chassis 204 can be simultaneously lowered, so that the lower surface of the docking block 207 can be in contact with the surface of the adjusting plate 404 accordingly, which can play a card-connecting and limiting effect on the adjusting plate 404. During the air tightness detection process of the vehicle-mounted brake pump, it plays a role of clamping and tightening to avoid shaking or loosening of the vehicle-mounted brake pump. On the contrary, after the telescopic tube 205 is away from the surface of the vehicle-mounted brake pump, the telescopic plate 413 rebounds and resets, which is convenient for the staff to take the vehicle-mounted brake pump, and the operation is convenient and simple.
