Detailed Description

The following detailed description is made with reference to the accompanying drawings and examples:

the function test machine that this application embodiment provided is mainly used for testing automobile brake. It should be noted here that the automobile brake includes a brake body, a lever rotatably disposed on the brake body, an adjuster connected to an output end of the lever and movably disposed on the brake body, and a push plate connected to an output end of the adjuster and movably disposed on the brake body. The push disc is used for pushing the brake pad to move; when the automobile brake is in work, a user treads a pedal of an automobile, the lever rotates, the adjuster rotates under the driving of the lever, the push disc moves under the driving of the adjuster, and the brake pad moves under the pushing of the push disc, so that the brake operation is realized.

Referring to fig. 1, the function testing machine includes a positioning mechanism 10, a first testing mechanism 20, a second testing mechanism 30, and a third testing mechanism 40. Positioning mechanism 10 is used for bearing stopper body to the stopper body is fixed a position, thereby realizes the location of lever, regulator and push away the dish, so, makes automobile brake's lever, regulator and push away the dish all be located the test position, is convenient for go on smoothly of lever, regulator and the test work who pushes away the dish. The first testing mechanism 20, the second testing mechanism 30 and the third testing mechanism 40 are all arranged on the same side of the positioning mechanism 10, and the first testing mechanism 20, the second testing mechanism 30 and the third testing mechanism 40 are mutually connected or distributed at intervals; the first testing mechanism 20, the second testing mechanism 30 and the third testing mechanism 40 are all disposed above the positioning mechanism 10.

Referring to fig. 2, the first testing mechanism 20 includes a first frame 21, a pressing rod mechanism 22, a first displacement sensor 23 and a pressure sensor 24, the pressing rod mechanism 22 is disposed on the first frame 21 and can press the lever to rotate the lever, and the first displacement sensor 23 and the pressure sensor 24 are respectively disposed on the pressing rod mechanism 22. During the test lever, depression bar mechanism 22 extrudees the lever for the lever rotates, and first displacement sensor 23 measures the extrusion displacement when depression bar mechanism 22 extrudes the lever, thereby obtains the rotation displacement of lever when rotating, and pressure sensor 24 measures the pressure value that depression bar mechanism 22 extrudes the lever, and through the rotation displacement of analysis first displacement sensor 23 and pressure sensor 24's pressure value, can acquire the operating condition and the in service behavior of lever, thereby guarantee the function of lever. After the pressing rod mechanism 22 completes the action of extruding the lever once, namely the pressure sensor 24 and the first displacement sensor 23 complete the measurement work once, at the moment, the pressing rod mechanism 22 can reset to wait for the next extrusion action, so that the operation of extruding the lever for multiple times is realized, and the rotating displacement of the lever and the pressure value of the lever extruded by the pressing rod mechanism 22 are obtained for multiple times.

It should be noted that in this embodiment, when testing the lever, the pressing rod mechanism 22 presses the lever, and generally stops the pressing action when the push plate moves to the preset position, that is, the lever completes the rotation, and the pressing rod mechanism 22 completes the pressing action, at this time, the first displacement sensor 23 can obtain the rotation displacement of the lever after the lever stops the rotation, that is, the rotation displacement of the lever when the push plate moves to the preset position. It should be noted here that, generally, in order to adapt to the abrasion condition of the push disc or the brake pad during the working process, when the push disc moves to drive the brake pad to brake each time, the adjuster provides a certain displacement compensation for the push disc, thereby ensuring that the push disc can drive the brake pad to brake; thus, the lever is pressed by the pressing rod mechanism 22 each time to make the push plate move, the adjuster can compensate for the movement of the push plate by a certain displacement, and theoretically, when the push plate moves to a preset position each time, the movement displacement of the push plate is different, correspondingly, the rotation displacement of the lever is also different. Therefore, the lever is squeezed for many times to respectively enable the push disc to move to the preset position, so that the rotating displacement of the lever after the rotation is completed is obtained for many times, the compensation quantity of the adjuster to the push disc after the lever rotates every time can be obtained besides the working state and the using condition of the lever, and therefore the compensation uniformity condition of the adjuster is obtained.

Referring to fig. 7, the second testing mechanism 30 includes a second frame 31, a rotating mechanism 32 and a torque sensor 33, wherein the rotating mechanism 32 is disposed on the second frame 31 and can be connected to the adjustor, so as to rotate the adjustor or rotate under the driving of the adjustor. The torque sensor 33 is provided on the rotary mechanism 32, and measures the torque of the rotary mechanism 32 when the rotary mechanism 32 rotates, thereby acquiring the torque sensor 33 of the regulator; by analyzing the torque of the regulator, the working state and the use condition of the regulator can be obtained, so that the function of the regulator is ensured, and the test work of the regulator is completed. Wherein, in this embodiment, it removes to preset the position after rotatory the pushing away dish of rotary mechanism 32 drive regulator, perhaps, lever drive regulator rotates so that the pushing away dish removes to preset the position after, torque sensor 33 accomplishes a torque measurement work, rotary mechanism 32 can reset this moment, thereby drive the regulator and reset, with the test work of waiting next time, so, rotary mechanism 32 can rotate regulator or rotary mechanism 32 many times under the drive of regulator rotatory many times, torque sensor 33 can acquire the moment of torsion of regulator many times.

Referring to fig. 10, the third testing mechanism 40 includes a third frame 41, a first moving member 222 and a second displacement sensor 43, the first moving member 42 is movably disposed on the second frame 31 and can move to abut against the pushing plate before the testing operation, and when the pushing plate moves, the first moving member 42 can move under the pushing of the pushing plate. The second displacement sensor 43 is disposed on the first moving member 42 to measure the displacement of the first moving member 42. It can be understood that, during the test pushing jack, first moving member 42 moves to supporting in the pushing jack, the pushing jack moves in order to promote first moving member 42 under the drive of regulator, first moving member 42 takes place to move under the promotion of pushing jack, second displacement sensor 43 and first moving member 42 synchronous motion to measure the displacement of first moving member 42, thereby obtain the displacement of pushing jack, through the displacement of analysis pushing jack, can acquire the operating condition and the in service behavior of pushing jack, thereby guarantee the function of pushing jack. After the first moving part 42 moves under the pushing of the pushing disc, the second displacement sensor 43 completes one displacement measurement, at the moment, the pushing disc can be reset under the driving of the regulator, and the first moving part 42 can also be reset to be abutted against the pushing disc again to wait for the next test operation, so that the first moving part 42 can move under the pushing of the pushing disc for many times, and then the second displacement sensor 43 can acquire the moving displacement of the pushing disc for many times.

It will be appreciated that the push plate can be moved to the preset position by the actuator, and the second displacement sensor 43 can measure the displacement of the push plate when the push plate is moved to the preset position. In this embodiment, move to preset position many times through the pushing jack to obtain the displacement when the pushing jack moves to preset position many times, can also obtain the compensation volume of pushing jack after the pushing jack moves every time, so, obtain the compensation homogeneity condition of regulator.

Wherein, in this embodiment, when the push pedal moves to preset position, the push pedal is in its position when driving the brake block and accomplish brake operation, so, the test in this embodiment has simulated the sight of car brake when actually carrying out brake operation, has improved the authenticity and the reliability of test.

In this embodiment, the function testing machine has two testing modes for the automobile brake, which are specifically as follows:

first, the rotating mechanism 32 is moved to the adjuster, and the first moving member 42 is moved to abut against the pushing plate. Then, the lever is extruded by the pressure lever mechanism 22 to rotate, the first displacement sensor 23 measures the rotation displacement of the lever when the lever rotates, and the pressure sensor 24 measures the pressure value of the lever extruded by the pressure lever mechanism 22; meanwhile, the adjuster rotates under the drive of the lever, the rotating mechanism 32 rotates under the drive of the adjuster, and the torque sensor 33 measures the torque of the adjuster; meanwhile, the push disc moves to the preset position under the driving of the adjustor, the first moving member 42 moves to the preset position under the pushing of the push disc, and the second displacement sensor 43 measures the moving displacement of the push disc; finally, the pressing lever mechanism 22 is reset to release the lever, thereby resetting the lever, at which time the rotating mechanism 32 is reset and rotates the actuator, thereby bringing the actuator and the push plate to reset for the next test work.

Second, the rotating mechanism 32 is moved to the adjuster, and the first moving member 42 is moved to abut against the pushing plate. Then, the rotating mechanism 32 rotates the adjuster so that the torque sensor 33 measures the torque of the adjuster; meanwhile, the push disc moves to the preset position under the driving of the adjustor, the first moving member 42 moves to the preset position under the pushing of the push disc, and the second displacement sensor 43 measures the moving displacement of the push disc; finally, the rotating mechanism 32 is reset and rotates the actuator, thereby bringing the actuator and the push plate to reset for the next test operation.

It can be understood that, when the function testing machine tests the automobile brake, the first testing mode may be adopted, the second testing mode may also be adopted, and of course, the first testing mode and the second testing mode may also be used in a mixed manner, and the order of use of the first testing mode and the second testing mode is not limited herein.

In the embodiment of the application, the function testing machine comprises a positioning mechanism 10, a first testing mechanism 20, a second testing mechanism 30 and a third testing mechanism 40, when the automobile brake is tested, a lever is extruded by a pressure lever mechanism 22 and rotates, the rotation displacement of the lever during rotation is measured by a first displacement sensor 23, and the pressure value of the lever extruded by the pressure lever mechanism 22 is measured by a pressure sensor 24, so that the rotation displacement of the lever and the pressure of extruding the lever are obtained, and the lever is tested; the rotating mechanism 32 rotates the regulator, or the lever rotates under the extrusion of the pressure lever mechanism 22 to drive the regulator to rotate, the rotating mechanism 32 rotates under the driving of the regulator, and at the moment, the torque sensor 33 measures the torque of the regulator to realize the test work of the regulator; the first moving member 42 moves to abut against the push disc, when the adjuster rotates, the push disc is driven to move to a preset position, at the moment, the first moving member 42 moves under the pushing of the push disc and moves to the preset position, and the second displacement sensor 43 measures the moving displacement of the push disc, so that the test work of the push disc is realized. Therefore, the function testing machine can simultaneously test the lever, the regulator and the push disc of the automobile brake, and the test integrity of the automobile brake is ensured, so that the function of the automobile brake is ensured; and when the automobile brake is tested, a plurality of devices are not required to be arranged to test the lever, the regulator and the push disc respectively, so that the integral structure of the function testing machine is simplified.

Referring to fig. 2, in the present embodiment, the pressing rod mechanism 22 includes a first driving member 221, a second moving member 222 and an extrusion rod 223, the first displacement sensor 23 is disposed on the second moving member 222, and the pressure sensor 24 is disposed on the extrusion rod 223. The first driving member 221 is disposed on the first frame 21, and the second moving member 222 is connected to an output end of the first driving member 221 and moves under the driving of the first driving member 221. The pressing rod 223 is rotatably disposed on the second moving part 222, and is driven by the second moving part 222 to press the lever and swing relative to the second moving part 222, so that the pressing rod 223 can better abut against the lever, and the pressing rod 223 is prevented from disengaging from the lever. Here, if the moving direction of the second moving part 222 is set to be the first direction Z, the second moving part 222 can move towards or away from the lever along the first direction Z under the driving of the first driving part 221, and the pressing rod 223 moves towards the lever along the first direction Z under the driving of the second moving part 222 and presses the lever or moves away from the lever to disengage from the lever. It can be understood that the test operation steps of the plunger mechanism 22 are: the first driving part 221 is started, the second moving part 222 is driven by the first driving part 221 to move towards the lever along the first direction Z, here, the second moving part 222 can be slidably arranged on the first rack 21 through the matching of the guide rail and the sliding block, the extrusion rod 223 is driven by the second moving part 222 to move towards the lever along the first direction Z and extrude the lever, so that the lever rotates, and at the moment, the extrusion rod 223 swings relative to the second moving part 222 and is matched with the swinging operation of the lever, so that the state that the extrusion rod 223 tightly abuts against the lever is maintained, the first displacement sensor 23 and the second moving part 222 synchronously move to measure the displacement of the second moving part 222 moving along the first direction Z, and the pressure sensor 24 and the extrusion rod 223 synchronously move to measure the pressure value when the extrusion rod 223 extrudes the lever; after the lever is squeezed by the squeezing rod 223 and the pushing disc moves to the preset position, the first driving part 221 drives the second moving part 222 to move away from the lever along the first direction Z so as to reset, the squeezing rod 223 moves away from the lever along the first direction Z under the driving of the second moving part 222 so as to break away from the lever and reset, and therefore the resetting of the lever is achieved, and the squeezing rod 223 can squeeze the lever next time.

In this embodiment, the swing plane of the pressing rod 223 is parallel to the rotation plane of the lever, so that when the pressing rod 223 presses the lever, the pressing rod 223 swings relative to the second moving member 222, and can adapt to the rotation of the lever, so as to better abut against and press the lever, and prevent the pressing rod 223 from separating from the lever due to the rotation of the lever when pressing the lever. Wherein the swinging plane of the pressing bar 223 is perpendicular to the second direction X1, and the second direction X1 is perpendicular to the first direction Z. It will be appreciated that when the pressing rod 223 moves along the first direction Z and presses the lever, the lever rotates around the axis extending along the second direction X1, and the pressing rod 223 correspondingly swings around the axis extending along the second direction X1 to better abut against and press the lever, so as to prevent the pressing rod 223 from being disengaged from the lever.

In the present embodiment, the first direction Z is a vertical direction, and the second direction X1 is a horizontal direction, in which the pressing rod 223 is disposed downward, moves downward to press the lever during testing, and moves upward to disengage the lever after completing testing; of course, the first direction Z may also be arranged to form an angle greater than 0 ° with the vertical direction, while the first direction Z is still perpendicular to the second direction X1, and the specific orientations of the first direction Z and the second direction X1, i.e., the specific orientation of the pressing bar 223, are not limited herein.

In this embodiment, the end surface of the pressing rod 223 for pressing the lever is set to be a curved surface, so that the pressing rod 223 can better adapt to the rotation of the lever.

Referring to fig. 2-4, in the present embodiment, the pressing rods 223 and the first frame 21 are spaced apart from each other, the elastic structure 25 is connected between the pressing rods 223 and the first frame 21, and the pressing rods 223 tightly contact the elastic structure 25 and press the elastic structure 25 when swinging. It can be understood that, when the pressing rod 223 moves and presses the lever under the driving of the second moving member 222, the pressing rod 223 swings relative to the lever and abuts against and presses the elastic structure 25, so that the elastic structure 25 is in a force accumulation state, and thus, the pressing rod 223 abuts against the lever under the elastic action of the elastic structure 25, so that the pressing rod 223 can be better adapted to the rotation of the lever, and the abutting state of the pressing rod 223 and the lever is ensured, the pressing rod 223 is prevented from being separated from the lever when swinging, and the stability of the pressing rod 223 when swinging is improved.

In a specific embodiment, the first frame 21 is provided with a limiting assembly 28, the limiting assembly 28 includes a first limiting member 281 and a second limiting member 282 slidably disposed on the first limiting member 281, the first limiting member 281 and the second limiting member 282 are both disposed in the first direction Z and communicated with each other, the extrusion rod 223 sequentially penetrates through the second limiting member 282 and the first limiting member 281 along the first direction Z, and can be driven by the second frame 222 to sequentially move in the second limiting member 282 and the first limiting member 281 along the first moving member direction Z. The second limiting member 282 and the first limiting member 281 form a limiting position along the second direction X1, so as to prevent the pressing rod 223 from moving along the second direction X1 in the second limiting member 282 and the first limiting member 281, respectively, and the pressing rod 223 can swing in the first limiting member 281 to drive the second limiting member 282 to slide on the first limiting member 281. In this embodiment, when the pressing rod 223 swings in the first limiting member 281, the pressing rod 223 drives the second limiting member 282 to slide, and at this time, the second limiting member 282 slides along a third direction Y1, where the third direction Y1 is perpendicular to the first direction Z and the second direction X1, respectively. Correspondingly, the second limiting members 282 and the first frame 21 are spaced apart from each other along the third direction Y1, and the elastic structure 25 extends along the third direction Y1 and is connected between the second limiting members 282 and the first frame 21. It can be understood that, when the first driving element 221 drives the second moving element 222 to move toward the lever along the first direction Z, the pressing rod 223 is driven by the second moving element 222 to move toward the lever along the first direction Z, and at this time, the pressing rod 223 moves in the second limiting element 282 and the first limiting element 281 along the first direction Z and extends out from the first limiting element 281 to abut against the lever; meanwhile, the extrusion rod 223 swings around the second moving member 222, and then the extrusion rod 223 swings in the first limiting member 281, so as to drive the second limiting member 282 to slide along the third direction Y1, at this time, the second limiting member 282 is slidably disposed on the first limiting member 281, and the second limiting member 282 and the first limiting member 281 form a limiting position along the second direction X1, so as to limit the extrusion rod 223 from swinging along the second direction X1, and ensure that the extrusion rod 223 accurately abuts against the lever when the lever is extruded.

In a specific embodiment, the first limiting member 281 is provided with a first limiting hole 283, the second limiting member 282 is provided with a second limiting hole 284, and the extrusion rod 223 sequentially penetrates through the second limiting hole 284 and the first limiting hole 283. The second limiting hole 284 is a circular hole adapted to the pressing rod 223, so that the pressing rod 223 can drive the second limiting member 282 to slide along the third direction Y1 when swinging, thereby preventing the pressing rod 223 from being separated from the lever due to the swinging of the pressing rod 223 in the second limiting member 282, and preventing the pressing rod 223 from sliding in the second limiting member 282 along the second direction X1. In a cross section of the first limiting member 281 perpendicular to the first direction Z, the first limiting hole 283 is a waist-shaped hole, and the first limiting hole 283 extends along the third direction Y1, so that the pressing rod 223 penetrates through the first limiting hole 283 and can swing in the first limiting hole 283. It should be noted here that the arrangement of the first limit hole 283 limits the swing stroke of the pressing rod 223, and avoids the pressing rod 223 from swinging infinitely to disengage from the lever.

It can be understood that when the pressing rod 223 is adjusted to face downward, the hand crank 2631 is shaken, and the gear 2632 is driven by the hand crank 2631 to rotate and engage with the arc-shaped rack 262, so as to drive the sliding member 27 to slide along the first arc-shaped slot 2611, thereby realizing the rotation of the first frame 21, and further realizing the adjustment of the orientation of the pressing rod 223. In this embodiment, the rotation of the rack can be realized by shaking the hand 2631, and the operation is very simple and labor-saving. In the specific embodiment, a bearing 2633 is further disposed on the adjusting structure 263, and the bearing 2633 is fixed on the sliding member 27, such that when the hand crank 2631 rotates, the gear 2632 engages with the arc-shaped rack 262, and the bearing 2633 drives the sliding member 27 to slide.

Wherein the rotation direction of the floating batch head 323 is perpendicular to the first direction Z.

It will be appreciated that the floating batch head 323 resiliently bears against the conditioner during testing of the conditioner. When the second driving member 321 is started, the plurality of safety couplers 3221 are driven to rotate by the second driving member 321, so that the floating bit 323 rotates the adjuster under the driving of the safety couplers 3221; alternatively, the floating bit 323 is rotated by the adjuster, so as to rotate the plurality of couplers 3221. The torque sensor 33 measures the torque of the regulator, and thus performs a test operation on the regulator. It should be further noted that the floating batch head 323 elastically abuts against the adjustor, so that the rotating operation of the floating batch head 323 on the adjustor is ensured, the inaccurate torque measurement result caused by the fact that the floating batch head 323 is separated from the adjustor in the rotating process is avoided, the flexible connection between the adjustor and the floating batch head 323 is realized, and the damage probability of the floating batch head 323 and the adjustor in the testing process is reduced.
