Description

Technical Field

[0001] The invention relates to the field of detection equipment, in particular to a brake caliper hydraulic test equipment. Background Art

[0002] The hydraulic leakage of the brake caliper is a key characteristic of the product, so after the brake caliper is produced, it is necessary to use a leakage test equipment to perform hydraulic testing on the brake caliper.

[0003] A Chinese patent with announcement number CN109060252A discloses a flexible testing device for testing the leakage of a brake caliper, including a base, a clamp, a lifting mechanism, a clamping mechanism and a quick plug. Before the brake caliper is tested, the quick plug needs to be inserted into the oil inlet hole of the brake caliper to perform a hydraulic test of the brake caliper.

[0004] When the brake caliper is undergoing a hydraulic leakage test, gas will be pressed into the brake caliper through the quick plug. When the gas enters the brake caliper, the connection between the quick plug and the brake caliper will be subject to a large impact force, causing the quick plug to shake significantly relative to the brake caliper, thereby affecting the sealing of the connection between the quick plug and the brake caliper, causing gas leakage, thereby affecting the accuracy of the brake caliper leakage test. Summary of the invention

[0007] By adopting the above technical solution, before the connector of the plug body is inserted into the oil inlet of the brake caliper, the handle is first grasped so that the connector of the plug body can be inserted into the oil inlet of the brake caliper. After the connector of the plug body is inserted into the oil inlet of the brake caliper, the handle is released so that the connector of the plug body and the oil inlet of the brake caliper are locked. Then, the first slider is controlled by the driving mechanism to move away from the top wall of the first slide groove. When the first slider moves, it will drive the pressing block to move closer to the plug body, and finally the pressing block presses the plug body against the bottom wall of the placement groove, thereby suppressing the shaking of the plug body when the gas enters the brake caliper, and ensuring the sealing of the connection between the quick plug and the brake caliper.

[0008] Preferably, an air intake channel and an exhaust channel connected to the outside are provided on the top wall of the first slide groove, and a third slide groove is provided on the fixed block, and the air intake channel and the exhaust channel are connected with the third slide groove. The driving mechanism includes an air source, a connecting pipe for connecting the air source and the air intake channel, a block slidably connected in the third slide groove, and a driving part for controlling the movement of the block, and a through hole is provided on the block. In an initial state, the block blocks the air intake channel, and the through hole is connected to the exhaust channel. The first sliding block conflicts with the top wall of the first slide groove.

[0009] By adopting the above technical solution, when the plug body is connected to the oil inlet of the brake caliper, the movement of the block is controlled by the driving unit, so that the through hole is no longer connected to the exhaust channel and the block blocks the exhaust channel. At the same time, the block no longer blocks the intake channel. Then the gas will be pressed into the intake channel through the connecting pipe, and then enter the first slide groove through the intake channel and push the first slider to move away from the top wall of the first slide groove, so that the first slider drives the pressing block to move and finally causes the pressing block to press the plug body against the bottom wall of the placement groove.

[0011] By adopting the above technical solution, after the connector of the plug body is extended into the oil inlet of the brake caliper, the handle will rebound and reset when the handle is released. During the rebound and reset process, the handle will collide with the lever and drive the lever to rotate. When the lever rotates, the first spring will be stretched and the gear will rotate. When the gear rotates, it will drive the rack to move away from the third slide groove. When the rack moves away from the third slide groove, it will drive the block to move. When the handle is reset, the movement of the lever will be restricted. At this time, the block blocks the exhaust channel and the intake channel is no longer blocked. Then, under the action of the gas, the pressing block presses the plug body against the bottom wall of the placement groove. Then the brake caliper leakage detection can be started. After the brake caliper is detected, the handle is held so that the handle moves close to the plug body to release the connection between the plug body and the brake caliper. When the handle moves close to the plug body, the first spring pulls the lever to rotate and reset. When the lever rotates and resets, it drives the gear to rotate and reset. When the gear rotates and resets, it drives the rack to move and reset. When the rack moves and resets, it drives the block to move and reset, so that the block blocks the intake channel, and the through hole is connected to the exhaust channel. The gas in the first slide groove is discharged through the exhaust channel, and the multiple elastic parts rebound and drive the first slider to move and reset. When the first slider moves and resets, it drives the pressure block to move and reset, thereby releasing the pressure of the pressure block on the plug body, so that the plug body can be taken out of the brake caliper.

[0012] Preferably, a U-shaped groove is provided on the bottom surface of the pressure block, the notch of the U-shaped groove faces the bottom wall of the placement groove, and a rubber pad is provided on the side wall of the U-shaped groove. When the connector of the plug body is inserted into the oil inlet of the brake caliper, the plug body faces the notch of the U-shaped groove and is located on the movement path of the U-shaped groove.

[0013] By adopting the above technical solution, a U-shaped groove is provided to enhance the suppressing effect of the pressing block on the shaking of the plug body.

[0014] Preferably, a guide block is provided on the outer wall of the plug body, and a guide groove slidably matched with the guide block is opened on the bottom wall of the placement groove. When the guide block is slidably connected in the guide groove, the connector of the plug body faces the oil inlet of the brake caliper.

[0015] By adopting the above technical solution, it is convenient for the staff to insert the plug body into the oil inlet of the brake caliper, and at the same time limit the position of the plug body so that the pressing block can accurately press the plug body.

[0016] Preferably, the elastic member is a second spring, one end of a plurality of the second springs abuts against the bottom wall of the first slide groove, and the other ends of a plurality of the second springs abuts against the bottom wall of the first slide block.

[0017] By adopting the above technical solution, the gas enters the first slide groove through the air inlet channel, which drives the first slider to move away from the top wall of the first slide groove, and the movement of the first slider causes the multiple second springs to be compressed. When the gas is discharged from the first slide groove through the exhaust channel, the multiple second springs will rebound and drive the first slider to move back to its original position.

[0018] Preferably, a plurality of guide rods are provided in the first sliding groove, the first sliding block is slidably connected to the plurality of guide rods, and a plurality of the second spring sleeves are respectively sleeved on the plurality of guide rods.

[0019] By adopting the above technical solution, the setting of the guide rod can guide the movement direction of the first slider, and can also guide the deformation of the second spring to ensure the driving effect of the second spring on the first slider.

[0020] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention drives the lever to rotate by the movement of the handle to finally control whether the block blocks the intake channel and the exhaust channel; 2. The pressing block of the present invention presses the quick plug against the bottom wall of the placement groove, thereby suppressing the shaking of the plug body when the gas enters the brake caliper, and ensuring the sealing of the connection between the quick plug and the brake caliper; 3. The present invention further enhances the limiting effect of the pressure block on the brake caliper by providing a U-shaped groove on the pressure block. BRIEF DESCRIPTION OF THE DRAWINGS

Two fixing blocks 3 are fixed on the body 1, and the two fixing blocks 3 are respectively located on one side of the two first clamps 11. The two fixing blocks 3 are provided with placement grooves 31 for placing the plug bodies 21 along the Y-axis direction. A guide groove 39 for slidingly cooperating with the guide block 23 is provided on the bottom wall of the placement groove 31 along the Y-axis direction. When the guide block 23 is slidably connected in the guide groove 39, the connector of the plug body 21 faces the oil inlet of the brake caliper.

Two guide rods 44 are fixed in the first slide groove 32, and the axes of the two guide rods 44 are parallel to the Z-axis. A first slider 41 is provided in the first slide groove 32, and the two ends of the first slider 41 are respectively connected to the two guide rods 44 in a sliding manner along the Z-axis direction. A pressing block 42 is provided at the bottom of the first slider 41, and the pressing block 42 is connected to the second slide groove 33 in a sliding manner along the Z-axis direction. When the connector of the plug body 21 is inserted into the oil inlet of the brake caliper, the plug body 21 contacts the bottom wall of the placement groove 31, and the plug body 21 is located on the movement path of the pressing block 42.

[0032] Reference Figure 1 , Figure 3-Figure 5 Two elastic members 5 are provided in the first slide groove 32 for driving the first slider 41 to move toward the top wall of the first slide groove 32. The elastic members 5 are always in a compressed state. The elastic members 5 are second springs 51. The two second springs 51 are respectively sleeved on the two guide rods 44. One end of the two second springs 51 abuts against the bottom wall of the first slide groove 32, and the other end of the two second springs 51 abuts against the bottom wall of the first slider 41. When there is no external force, the two second springs 51 press the first slider 41 against the top wall of the first slide groove 32.

[0033] Reference Figure 1 , Figure 3-Figure 5 The body 1 is also provided with a driving mechanism 6 for driving the first slider 41 to move away from the top wall of the first slide groove 32. The driving force of the driving mechanism 6 on the first slider 41 is greater than the driving force of the elastic member 5 on the first slider 41. The top wall of the first slide groove 32 is provided with an air intake channel 34 and an air exhaust channel 35 connected to the outside. The air intake channel 34 is located above the air exhaust channel 35. The fixed block 3 is provided with a third slide groove 36 along the Z-axis direction. The third slide groove 36 connects the air intake channel 34 and the air exhaust channel 35. The driving mechanism 6 includes an air source 61, a connecting pipe 62 for connecting the air source 61 with the air intake channel 34, and a stopper 63 slidably connected to the third slide groove 36 along the Z-axis direction. The stopper 63 is provided with a through hole 631. In the initial state, the stopper 63 blocks the air intake channel 34, and the through hole 631 connects the air exhaust channel 35. The first slider 41 is in conflict with the top wall of the first slide groove 32. The air source 61 is an air compressor, and two air compressors are respectively fixed on both sides of the machine body 1.

[0034] Reference Figure 1 , Figure 3-Figure 5The top wall of the placement groove 31 is provided with a mounting cavity 37 along the Z-axis direction, and the bottom wall of the placement groove 31 is provided with a limit cavity 38 along the Z-axis direction, and the limit cavity 38 is located below the mounting cavity 37. The driving mechanism 6 also includes a driving part 7 for controlling the movement of the stopper 63, and the driving part 7 includes a rack 71 fixed on the bottom of the stopper 63, a gear 72 rotatably connected in the mounting cavity 37, a lever 73 fixed on the gear 72, a first spring 74 fixed in the limit cavity 38, and a limit block 75. The rack 71 is meshed with the gear 72, and the rotation axis of the gear 72 is parallel to the Y-axis. The bottom end of the lever 73 extends into the limit cavity 38, and the limit block 75 is located on the rotation path of the lever 73. One end of the first spring 74 is fixedly connected to the side wall of the limit cavity 38, and the other end of the first spring 74 is fixedly connected to the lever 73. The first spring 74 is always in a stretched state, and the resilience of the handle 22 is greater than the elastic force of the first spring 74. In the initial state, the first spring 74 pulls the lever 73 so that the lever 73 rests on the limit block 75. When the handle 22 is located in the placement groove 31, the lever 73 is located on the movement path of the handle 22.

[0035] Reference Figure 1-Figure 6 , the process of testing the equipment in this application is as follows: First, install the brake caliper to be tested on the first fixture 11, pick up the plug body 21 and then grasp the handle 22 so that the handle 22 is close to the plug body 21, then insert the guide block 23 into the guide groove 39 and push the plug body 21 so that the connector of the plug body 21 extends into the oil inlet of the brake caliper. After the connector of the plug body 21 is inserted into the oil inlet of the brake caliper, release the handle 22 so that the handle 22 moves to reset and the connector of the plug body 21 and the oil inlet of the brake caliper are locked with each other.

[0036] During the process of the handle 22 moving and resetting, it will collide with the lever 73 and drive the lever 73 to rotate. When the lever 73 rotates, it will drive the first spring 74 to be stretched and the gear 72 to rotate. When the gear 72 rotates, it will drive the rack 71 to move away from the third slide groove 36. When the rack 71 moves away from the third slide groove 36, it will drive the block 63 to move. Finally, when the handle 22 moves and resets to the initial position, the limiting lever 73 will also stop rotating and the handle 22 will limit the lever 73 from rotating. At this time, the block 63 blocks the exhaust channel 35, and the block 63 no longer blocks the intake channel 34. Then, the gas source 61 will press the gas into the first slide groove 32 through the connecting pipe and the intake channel 34.

[0037] Under the action of gas thrust, the first slider 41 will move in the direction away from the top wall of the first slide groove 32. When the first slider 41 moves, it will drive the two second springs 51 to be compressed and make the pressing block 42 move toward the plug body 21. Finally, the pressing block 42 presses the plug body 21 against the bottom wall of the placement groove 31. At this time, the outer surface of the plug body 21 fits the side wall of the U-shaped groove 43, and then the hydraulic leakage detection of the brake caliper can be started.

[0038] After the hydraulic leakage detection of the brake caliper is completed, hold the handle 22 so that the handle 22 moves close to the plug body 21 to release the lock between the plug body 21 and the brake caliper. When the handle 22 moves close to the plug body 21, the first spring 74 pulls the lever 73 to rotate and reset. When the lever 73 rotates and resets, it will drive the gear 72 to rotate and reset. When the gear 72 rotates and resets, it will drive the rack 71 to move and reset. When the rack 71 moves and resets, it will drive the block 63 to move and reset, so that the block 63 blocks the intake channel 34, and the through hole 631 is connected to the exhaust channel 35. The gas in the first slide groove 32 is discharged through the exhaust channel 35. The two second springs 51 rebound and drive the first slider 41 to move and reset. When the first slider 41 moves and resets, it drives the pressure block 42 to move and reset, thereby releasing the pressure of the pressure block 42 on the plug body 21, and then the plug body 21 can be pulled out of the brake caliper.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
