The one sides of the number of T-shaped circular blocks away from each other are respectively fixedly installed with C-shaped connecting rods. The one ends of the number of C-shaped connecting rods close to each other are respectively fixedly connected to the front and back surfaces of the ratchet disc.

[0015] Further, a pressure detection method for processing an automobile shock absorber is as follows:

[0016] S1: First, place the automobile shock absorber in the fixing groove and the C-shaped frame in the second fixing box. Then rotate the rotating rod. The rotating rod drives the rotating wheel to rotate. The rotating wheel drives the worm to rotate. The worm drives the threaded rod to rotate under the action of the worm gear. The threaded rod drives the mounting plate to rise. The mounting plate drives the first fixing box for placing the automobile shock absorber to rise. When the first fixing box and the second fixing box come into contact, at this time, the fixing groove and the C-shaped frame in the first fixing box just completely and snugly clamp the automobile shock absorber, so that the automobile shock absorber is fixed in the two first fixing boxes, avoiding the shaking of the automobile shock absorber when it is stressed and causing a measuring error, and at the same time improving the installation efficiency of the automobile shock absorber;

[0017] S2: After the first fixing box and the second fixing box are aligned, the rotating rod can be further rotated according to the height of the tester. The upward movement of the second fixing box drives the first fixing box to rise simultaneously. During the upward movement of the first fixing box, under the elastic force of the spring, the first fixing box and the second fixing box will be pressed closer together, effectively improving the stability of the device. At the same time, the height of the device can be adjusted according to the height of the tester to avoid discomfort caused by an inappropriate device height during operation;

[0018] S3: Before the test, start the hydraulic cylinder. The hydraulic cylinder drives the corresponding ratchet disc to move. The ratchet disc drives the force-applying gear to move under the action of the C-shaped connecting rod. During the movement of the force-applying gear, the hexagonal teeth on the force-applying gear will touch the diamond-shaped teeth below the tooth plate. Since the side surfaces of the teeth on the force-applying gear and the tooth plate are both arc-shaped, during the movement of the hydraulic cylinder, the hexagonal teeth on the force-applying gear will contact the diamond-shaped teeth on the tooth plate. Also, because the C-shaped connecting rod is slidably connected to the T-shaped circular groove, the force-applying gear is movably connected to the ratchet disc. Therefore, when the hexagonal teeth on the force-applying gear contact the diamond-shaped teeth on the tooth plate during the movement of the hydraulic cylinder, the force-applying gear will rotate to the left under the action of the force, causing the diamond-shaped teeth on the tooth plate and the hexagonal teeth on the force-applying gear to错开 and mesh, effectively improving the test efficiency and the error tolerance rate of tooth engagement, and avoiding wasting test time by repeatedly debugging the engagement of the force-applying gear and the tooth plate before the test. When the ratchet disc rotates to the right, the ratchet disc drives the T-shaped round block to move. When the T-shaped round block touches the edge of the T-shaped circular groove, it will drive the force-applying gear to rotate, and the block on the force-applying gear will卡住 the ratchet disc, thus preparing for the test state;

[0019] S4: After adjusting to the appropriate height, start the drive motor. The drive motor drives the rotating shaft to rotate, the drive motor drives the hydraulic cylinder to rotate, the hydraulic cylinder drives the hollow shaft to rotate, and the hollow shaft drives several force-applying gears to rotate. First, the force-applying gear with the fewest hexagonal teeth drives the tooth plate to move. The tooth plate drives the force-applying rod and the force-applying block away from the pressure sensor. After the hexagonal teeth disengage from the tooth plate, the force-applying block will be ejected under the action of the force-applying spring to impact the pressure sensor. The force received by the pressure sensor will drive the vehicle shock absorber to perform shock absorption. The impact value will be displayed and recorded on the processing screen, and then cooperate with the hydraulic cylinder to drive several force-applying gears to rotate the tooth plate in sequence for pressure detection, so that the vehicle shock absorber is subjected to different degrees of force detection, which is in line with the situation of the vehicle shock absorber being subjected to different degrees of force during driving on the vehicle and is closer to the test scenario;

[0020] S5: When the force block hits the pressure sensor due to the elastic force of the force spring, the force block will move horizontally on the two sliding limit rods under the action of the rectangular slider. Since the bar slider is slidably connected to the two sliding limit rods, when the force block hits the pressure sensor, the output direction and the force direction of the pressure sensor are in the same direction. Therefore, the pressure value detected by the pressure sensor is more accurate, eliminating the error caused by the force direction and the output direction not being on the same horizontal line, effectively improving the accuracy of the pressure value.

[0021] The present invention has the following beneficial effects:

[0022] (1) The present invention provides a pressure detection device for automobile shock absorber processing. First, the automobile shock absorber is placed in a fixed groove and a molded frame in a fixed box two, and then the rotating rod is rotated. The rotating rod drives the rotating wheel to rotate, and the rotating wheel drives the worm to rotate. The worm drives the threaded rod to rotate under the action of the worm wheel, and the threaded rod drives the mounting plate to rise. The mounting plate drives the fixed box one where the automobile shock absorber is placed to rise. When the fixed box one and the fixed box two are in contact, the fixed groove and the molded frame in the fixed box one just fit the automobile shock absorber completely, so that the automobile shock absorber is fixed in the two fixed boxes one, thereby avoiding the automobile shock absorber shaking when the automobile shock absorber is subjected to force, thereby causing a force measurement error, and also improving the installation efficiency of the automobile shock absorber;

[0023] (2) For a pressure detection device used in the processing of automotive shock absorbers according to the present invention, after the first fixed box and the second fixed box are fitted together, the rotating rod can be further rotated according to the height of the detector. When the second fixed box rises, it drives the first fixed box to rise simultaneously. During the rising process of the first fixed box, under the elastic force of the spring, the first fixed box and the second fixed box will be pressed closer together, effectively improving the stability of the device. At the same time, the height of the device can be adjusted according to the height of the detector to avoid discomfort caused by an inappropriate device height during operation. Before detection, the hydraulic cylinder is started. The hydraulic cylinder drives the corresponding ratchet disc to move. Under the action of the U-shaped connecting rod, the ratchet disc drives the force-applying gear to move. During the movement of the force-applying gear, the hexagonal teeth on the force-applying gear will touch the diamond-shaped teeth below the tooth plate. Since the side surfaces of the teeth on the force-applying gear and the tooth plate are both arc surfaces, during the movement of the hydraulic cylinder, the hexagonal teeth on the force-applying gear will contact the diamond-shaped teeth on the tooth plate. Also, because the U-shaped connecting rod is slidably connected to the T-shaped circular groove, the force-applying gear is movably connected to the ratchet disc. Therefore, when the hexagonal teeth on the force-applying gear contact the diamond-shaped teeth on the tooth plate during the movement of the hydraulic cylinder, the force-applying gear will rotate counterclockwise under the action of the force, causing the diamond-shaped teeth on the tooth plate and the hexagonal teeth on the force-applying gear to错开 and mesh, effectively improving the detection efficiency and the error tolerance of tooth meshing, and avoiding wasting detection time by repeatedly debugging the meshing of the force-applying gear and the tooth plate before testing. When the ratchet disc rotates clockwise, the ratchet disc drives the T-shaped circular block to move. When the T-shaped circular block touches the edge of the T-shaped circular groove, it will drive the force-applying gear to rotate, and the latch on the force-applying gear will lock the ratchet disc, thus preparing for the detection state;

[0024] (3) For a pressure detection device used in the processing of automotive shock absorbers according to the present invention, after adjusting to the appropriate height, the drive motor is started. The drive motor drives the rotating shaft to rotate, the drive motor drives the hydraulic cylinder to rotate, the hydraulic cylinder drives the hollow shaft to rotate, and the hollow shaft drives several force-applying gears to rotate. First, the force-applying gear with the fewest hexagonal teeth drives the tooth plate to move. The tooth plate drives the force-applying rod and the force-applying block away from the pressure sensor. After the hexagonal teeth disengage from the tooth plate, the force-applying block will be ejected under the action of the force-applying spring to impact the pressure sensor. The force received by the pressure sensor will drive the automotive shock absorber to perform shock absorption, and the impact value will be displayed and recorded on the processing screen. Then, in cooperation with the hydraulic cylinder, several force-applying gears are driven to rotate the tooth plate in sequence for pressure detection, enabling the automotive shock absorber to be subjected to different degrees of force detection, which is in line with the situation where the automotive shock absorber is subjected to different degrees of force during driving on the vehicle and is closer to the detection scenario;

[0025] (4) The present invention provides a pressure detection device for automobile shock absorber processing. When the force block is impacted by the elastic force of the force spring against the pressure sensor, the force block will move horizontally on two sliding limit rods under the action of the rectangular slider. Since the strip slider is slidably connected to the two sliding limit rods, when the force block impacts the pressure sensor, the output direction and the force direction of the pressure sensor are in the same direction. Therefore, the pressure value detected by the pressure sensor is more accurate, eliminating the error caused by the force direction and the output direction not being on the same horizontal line, and effectively improving the accuracy of the pressure value.

[0045] By setting the force measuring mechanism 02, when the first fixed box 2 and the second fixed box 201 are in contact, at this time, the fixed groove 11 and the U-shaped frame 10 in the first fixed box 2 just completely and snugly clamp the automobile shock absorber 13, so that the automobile shock absorber 13 is fixed in the two first fixed boxes 2, avoiding the shaking of the automobile shock absorber 13 when the automobile shock absorber 13 is stressed and causing a force measurement error, and at the same time improving the installation efficiency of the automobile shock absorber 13.

[0046] As Figure 2 shown, a display mechanism 03 is arranged on the back surface of the support seat 1.

After the diamond - shaped teeth on the toothed plate 21 disengage from the toothed plate 32, the force - applying block 6 will be ejected under the action of the force - applying spring 8 to impact the pressure sensor.

A clamping block 42 is hingedly installed in the activity groove 41. An arc-shaped telescopic rod 43 is fixedly installed on the outer wall of the clamping block 42. The top end of the arc-shaped telescopic rod 43 is fixedly connected to the activity groove 41. An arc-shaped spring 44 is wound around the arc-shaped telescopic rod 43. The bottom end of the arc-shaped spring 44 is fixedly connected to the clamping block 42. The top end of the arc-shaped spring 44 is fixedly connected to the activity groove 41. Two T-shaped circular grooves 45 are respectively formed on the front and back of the force application gear 35. A number of T-shaped circular blocks 46 are respectively slidably installed in the number of T-shaped circular grooves 45. One side of the number of T-shaped circular blocks 46 away from each other is respectively fixedly installed with a C-shaped connecting rod 47. One end of the number of C-shaped connecting rods 47 close to each other is respectively fixedly connected to the front and back of the ratchet disc 40.

[0057] By setting the adaptation mechanism 08, the hydraulic cylinder 33 drives the corresponding ratchet disc 40 to move. The ratchet disc 40 drives the force application gear 35 to move under the action of the C-shaped connecting rod 47. During the movement of the force application gear 35, the hexagonal teeth on the force application gear 35 will touch the diamond-shaped teeth below the tooth plate 32. Since the sides of the diamond-shaped teeth on the force application gear 35 and the tooth plate 32 are inclined planes, the hexagonal teeth on the force application gear 35 will drive the force application gear 35 to rotate during the approaching process. The T-shaped circular block 46 in the T-shaped circular groove 45 is used for limiting until the diamond-shaped teeth on the tooth plate 32 and the hexagonal teeth on the force application gear 35 are错开 and engaged, effectively improving the detection efficiency and the error tolerance rate of tooth engagement. When the ratchet disc 40 rotates, the ratchet disc 40 drives the T-shaped circular block 46 to move. When the T-shaped circular block 46 touches the edge of the T-shaped circular groove 45, it will drive the force application gear 35 to rotate. The clamping block 42 on the force application gear 35 will clamp the ratchet disc 40, thus preparing for the detection state.

[0058] As Figure 1-Figure 11 shown, a pressure detection method for processing an automotive shock absorber is as follows:

[0059] S1: First, place the automotive shock absorber 13 in the fixing groove 11 and the C-shaped frame 10 in the fixing box two 201. Then rotate the rotating rod 27. The rotating rod 27 drives the rotating wheel 26 to rotate. The rotating wheel 26 drives the worm 25 to rotate. The worm 25 drives the threaded rod 20 to rotate under the action of the worm gear 24. The threaded rod 20 drives the mounting plate 21 to rise. The mounting plate 21 drives the fixing box one 2 where the automotive shock absorber 13 is placed to rise. When the fixing box one 2 and the fixing box two 201 are in contact, at this time, the fixing groove 11 and the C-shaped frame 10 in the fixing box one 2 just completely and accurately clamp the automotive shock absorber 13, fixing the automotive shock absorber 13 in the two fixing boxes one 2, avoiding the shaking of the automotive shock absorber 13 during the force application of the automotive shock absorber 13 and causing a force measurement error, and at the same time improving the installation efficiency of the automotive shock absorber 13;

[0060] S2: After the fixed box one 2 and the fixed box two 201 are fitted, the rotating rod 27 can be further rotated according to the height of the detector. The rising of the fixed box two 201 drives the fixed box one 2 to rise simultaneously. During the rising process of the fixed box one 2, under the elastic force of the spring 30, the fixed box one 2 and the fixed box two 201 will be pressed closer together, effectively improving the stability of the device. At the same time, the height of the device can be adjusted according to the height of the detector, avoiding discomfort caused by inappropriate device height during operation;

[0061] S3: Before detection, start the hydraulic cylinder 33. The hydraulic cylinder 33 drives the corresponding ratchet disc 40 to move. The ratchet disc 40 drives the force-applying gear 35 to move under the action of the U-shaped connecting rod 47. During the movement of the force-applying gear 35, the hexagonal teeth on the force-applying gear 35 will touch the diamond-shaped teeth below the tooth plate 32. Since the side surfaces of the teeth on the force-applying gear 35 and the tooth plate 32 are both arc surfaces, during the movement of the hydraulic cylinder 33, the hexagonal teeth on the force-applying gear 35 will contact the diamond-shaped teeth on the tooth plate 32. Also, because the U-shaped connecting rod 47 is slidably connected to the T-shaped circular groove 45, the force-applying gear 35 is movably connected to the ratchet disc 40. Therefore, when the hexagonal teeth on the force-applying gear 35 contact the diamond-shaped teeth on the tooth plate 32 during the movement of the hydraulic cylinder 33, the force-applying gear 35 will rotate to the left under the action of the force, causing the diamond-shaped teeth on the tooth plate 32 and the hexagonal teeth on the force-applying gear 35 to错开 and mesh, effectively improving the detection efficiency and the error tolerance rate of tooth engagement, and avoiding wasting detection time by repeatedly debugging the engagement of the force-applying gear 35 and the tooth plate 32 before testing. When the ratchet disc 40 rotates to the right, the ratchet disc 40 drives the T-shaped circular block 46 to move. When the T-shaped circular block 46 touches the edge of the T-shaped circular groove 45, it will drive the force-applying gear 35 to rotate, and the block 42 on the force-applying gear 35 will catch the ratchet disc 40, thus preparing for the detection state;

[0062] S4: After adjusting to the appropriate height, start the drive motor 39. The drive motor 39 drives the rotating circular shaft 38 to rotate. The drive motor 39 drives the hydraulic cylinder 33 to rotate. The hydraulic cylinder 33 drives the hollow shaft 34 to rotate. The hollow shaft 34 drives several force-applying gears 35 to rotate. First, the force-applying gear 35 with the fewest hexagonal teeth drives the tooth plate 32 to move. The tooth plate 32 drives the force-applying rod 7 and the force-applying block 6 away from the pressure sensor. After the hexagonal teeth disengage from the tooth plate 32, the force-applying block 6 will be ejected by the force of the force-applying spring 8 and hit the pressure sensor. The force received by the pressure sensor will drive the vehicle shock absorber 13 to perform shock absorption. The impact value will be displayed and recorded on the processing screen 16. Then, in cooperation with the hydraulic cylinder 33, several force-applying gears 35 will drive the tooth plate 32 to rotate in sequence for pressure detection, enabling the vehicle shock absorber 13 to be subjected to different degrees of force detection, which is in line with the situation of the vehicle shock absorber 13 receiving different degrees of force during driving on the vehicle and is closer to the detection scenario;

[0063] S5: When the force block 6 hits the pressure sensor due to the elastic force of the force spring 8, the force block 6 will move horizontally on the two sliding limit rods 4 under the action of the rectangular slider 5. Since the strip slider 9 is slidingly connected to the two sliding limit rods 4, when the force block 6 hits the pressure sensor, the output direction and the force direction of the pressure sensor are in the same direction. Therefore, the pressure value detected by the pressure sensor is more accurate, eliminating the error caused by the force direction and the output direction not being on the same horizontal line, effectively improving the accuracy of the pressure value.

3. A pressure detection method for automobile shock absorber processing, using a pressure detection device for automobile shock absorber processing as claimed in claim 2, characterized in that: The method steps are as follows: S1: First, place the vehicle shock absorber (13) in the fixing groove (11) and the C-shaped frame (10) in the second fixing box (201). Then, rotate the rotating rod (27). The rotating rod (27) drives the rotating wheel (26) to rotate. The rotating wheel (26) drives the worm (25) to rotate. Under the action of the worm gear (24), the worm (25) drives the threaded rod (20) to rotate. The threaded rod (20) drives the mounting plate (21) to rise. The mounting plate (21) drives the first fixing box (2) that places the vehicle shock absorber (13) to rise. When the first fixing box (2) contacts the second fixing box (201), at this time, the fixing groove (11) and the C-shaped frame (10) in the first fixing box (2) exactly and completely clamp the vehicle shock absorber (13), fixing the vehicle shock absorber (13) in the two first fixing boxes (2), avoiding the shaking of the vehicle shock absorber (13) when it is stressed, which may cause measurement errors, and at the same time improving the installation efficiency of the vehicle shock absorber (13); S2: After the first fixing box (2) and the second fixing box (201) are fitted, continue to rotate the rotating rod (27) according to the height of the tester. The rising of the second fixing box (201) drives the first fixing box (2) to rise simultaneously. During the rising process of the first fixing box (2), under the elastic force of the spring (30), the first fixing box (2) and the second fixing box (201) will be pressed closer, effectively improving the stability of the device. At the same time, adjust the height of the device according to the height of the tester to avoid discomfort caused by inappropriate device height during operation; S3: Before the test, start the hydraulic cylinder (33). The hydraulic cylinder (33) drives the corresponding ratchet disc (40) to move. The ratchet disc (40) drives the force-applying gear (35) to move under the action of the C-shaped connecting rod (47). During the movement of the force-applying gear (35), the hexagonal teeth on the force-applying gear (35) will touch the diamond-shaped teeth below the toothed plate (32). Since the side surfaces of the teeth on the force-applying gear (35) and the toothed plate (32) are both arc surfaces, during the movement of the hydraulic cylinder (33), the hexagonal teeth on the force-applying gear (35) will contact the diamond-shaped teeth on the toothed plate (32). Also, because the C-shaped connecting rod (47) is slidably connected to the T-shaped circular groove (45), the force-applying gear (35) is movably connected to the ratchet disc (40). Therefore, when the hexagonal teeth on the force-applying gear (35) contact the diamond-shaped teeth on the toothed plate (32) during the movement of the hydraulic cylinder (33), the force-applying gear (35) will rotate to the left under the action of the force, causing the diamond-shaped teeth on the toothed plate (32) and the hexagonal teeth on the force-applying gear (35) to错开 and mesh, effectively improving the test efficiency and the error tolerance of tooth meshing, avoiding wasting test time by repeatedly debugging the meshing of the force-applying gear (35) and the toothed plate (32) before the test. When the ratchet disc (40) rotates to the right, the ratchet disc (40) drives the T-shaped circular block (46) to move. When the T-shaped circular block (46) touches the edge of the T-shaped circular groove (45), it will drive the force-applying gear (35) to rotate, and the block (42) on the force-applying gear (35) will lock the ratchet disc (40), thus preparing for the pre-test state; S4: After adjusting to a suitable height, the drive motor (39) is started, the drive motor (39) drives the rotating shaft (38) to rotate, the drive motor (39) drives the hydraulic cylinder (33) to rotate, the hydraulic cylinder (33) drives the hollow shaft (34) to rotate, the hollow shaft (34) drives a plurality of force gears (35) to rotate, firstly, the force gear (35) with the least hexagonal teeth drives the tooth plate (32) to move, the tooth plate (32) drives the force rod (7) and the force block (6) to leave the pressure sensor, and after the hexagonal teeth are separated from the tooth plate (32), the force rod (7) and the force block (6) are moved to the pressure sensor. Under the action of the spring (8), the force block (6) will pop out of the impact pressure sensor, and the force applied to the pressure sensor will drive the automobile shock absorber (13) to perform shock absorption. The impact value will be displayed on the processing screen (16) and recorded for processing. Then, in conjunction with the hydraulic cylinder (33), a plurality of force applying gears (35) will drive the toothed plate (32) to rotate in sequence to perform pressure detection, so that the automobile shock absorber (13) is subjected to different degrees of force detection. This detection conforms to the situation that the automobile shock absorber (13) is subjected to different degrees of force while driving on the automobile, and is closer to the detection scenario; S5: When the force block (6) is impacted by the elastic force of the force spring (8) against the pressure sensor, the force block (6) moves horizontally on the two sliding limit rods (4) under the action of the rectangular slider (5). Since the strip slider (9) is slidably connected to the two sliding limit rods (4), when the force block (6) impacts the pressure sensor, the output direction and the force direction of the pressure sensor are in the same direction. Therefore, the pressure value detected by the pressure sensor is more accurate, eliminating the error caused by the force direction and the output direction not being on the same horizontal line, and effectively improving the accuracy of the pressure value.
