Description

Technical Field

[0001] The invention relates to the technical field of process flow for assembling a shock absorber assembly of an automobile suspension system, and in particular to a measuring tool and a method for detecting the angle of an external connecting sleeve component of the shock absorber assembly. Background Art

[0002] It is used in the process of assembling the shock absorber assembly of the automobile suspension system to detect the installation angle of the external connecting sleeve assembly of the shock absorber assembly. With the continuous improvement of the automation level of automobile assembly, the installation dimensions of the shock absorber assembly are becoming more and more stringent. The installation angle of the external connecting sleeve assembly of the shock absorber assembly is just part of the installation dimensions of the shock absorber assembly. If this dimension is out of tolerance, it will make it difficult to install the shock absorber during the assembly of the whole vehicle, and in serious cases, it cannot be installed.

[0003] Currently, the three bolts on the external sleeve assembly are used as the positioning reference, and the pin shaft is used to pass through the mounting hole on the bracket opening as a detection method. When this method is used for detection, the oil storage cylinder of the shock absorber assembly, the external sleeve assembly and the detection gauge are in contact. At this time, the angle between the external sleeve assembly and the damper (that is, the installation angle of the external sleeve assembly of the shock absorber assembly) has been fixed, and the external sleeve assembly cannot rotate freely. If the angle is found to be unqualified during the detection, it is difficult to adjust, and it cannot be quickly adjusted to the correct angle, resulting in reduced assembly efficiency. In addition, the current detection methods all use manual judgment, which has the risk of unqualified flat outflow. Summary of the invention

[0004] The present invention provides an angle detection gauge and a detection method for an external connecting sleeve assembly of a shock absorber assembly, which solves the problem that the oil storage cylinder, the external connecting sleeve assembly and the detection gauge of the shock absorber assembly are in contact with each other, so that the installation angle of the external connecting sleeve assembly of the shock absorber assembly is fixed, and the external connecting sleeve assembly cannot rotate freely. If an unqualified angle is found during detection, adjustment is difficult, and it is impossible to quickly adjust to the correct angle, resulting in reduced assembly efficiency. In addition, the current detection means all use manual judgment, which has the risk of unqualified flat flow out.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] A bottom plate, a bracket opening detection assembly, a liquid storage cylinder height detection plate and an external connecting sleeve detection assembly, the bracket opening detection assembly, the liquid storage cylinder height detection plate and the external connecting sleeve detection assembly are respectively arranged on the bottom plate from left to right, the bracket opening detection assembly includes a first sensing device, the first sensing device is fixedly arranged on the bracket opening detection assembly, the external connecting sleeve detection assembly includes a second sensing device, the second sensing device is fixedly arranged on the external connecting sleeve detection assembly, a third sensing device is arranged at the liquid storage cylinder height detection plate, and the first sensing device, the second sensing device and the third sensing device are all electrically connected to the controller.

[0007] The beneficial effect of the present invention is that, since the contact points between the detection gauge and the shock absorber assembly are the oil storage cylinder and the piston rod screw, the detection gauge does not directly contact the external connection sleeve assembly, so the external connection sleeve assembly can rotate freely. When the angle is found to be unqualified during detection, it can be directly rotated quickly on the detection gauge, and the angle of the external connection sleeve assembly can be adjusted to the corresponding angle to continue detection, and the adjustment is convenient. During detection, the cylinder will push the fixing member to insert into the first light hole of the slide rail fixing block, so that the shock absorber assembly is restricted up and down and left and right and cannot be taken out. After the detection is qualified, the cylinder drives the fixing member to automatically withdraw, the shock absorber assembly restriction is released, and the shock absorber assembly can be taken out again to avoid the outflow of unqualified angle products. Such a structure is simple, fast and convenient to operate. When operating, the operator only needs to place the shock absorber assembly on the detection gauge and pull the detection plates on the left and right sides of the slide rail to the specified position. If the bolts on the external connection sleeve assembly can pass through the second light hole on the external connection sleeve bolt angle detection plate, it is qualified, and if they cannot pass through, it is unqualified. It is simple and easy to use, and the operation is effortless.

[0008] On the basis of the above technical solution, the present invention also makes the following improvements.

[0009] Furthermore, the bottom surface of the base plate is set on the workbench, and a guide rail is set on the top of the base plate in the length direction of the base plate. A first slider and a second slider are set at both ends of the guide rail. The second slider and the first slider are slidably set on the guide rail, and a limit ring is also set at one end of the guide rail where the first slider is set.

[0010] The beneficial effect of adopting the above further scheme is that a guide rail is set on the bottom plate, and the second slider can drive the bracket opening detection component and the first slider to drive the external connection sleeve detection component to slide back and forth on the guide rail to fix and detect the shock absorber assembly. The operation is simple, fast and convenient. When operating, the operator only needs to place the shock absorber assembly on the detection gauge and pull the detection plates on the left and right sides of the guide rail to the specified position. If the bolts on the external connection sleeve assembly can pass through the external connection sleeve bolt angle detection plate, it is qualified, and if they cannot pass through, it is unqualified. It is simple and easy to use and the operation is effortless.

[0011] Furthermore, the bracket opening detection component also includes a first fixed component part and a first movable component part. The bracket opening detection component is detachably mounted on one end of the base plate having a first slider, the first fixed component part is detachably mounted on the base plate, the first movable component part is detachably mounted on the first slider, the first sensing device is mounted on the fixed component part, and the first movable component part is movable relative to the first fixed component part.

[0012] The beneficial effect of adopting the above further scheme is that the positioning block and the open positioning mounting plate are moved to the bracket opening of the shock absorber assembly by the first moving assembly part, and the positioning block is slid into the bracket opening of the shock absorber assembly, and then the first moving assembly part is locked by the first fixed assembly part, so that the shock absorber assembly is axially fixed, so that the external connecting sleeve assembly of the shock absorber assembly does not directly contact the detection gauge, and the external connecting sleeve assembly of the shock absorber assembly can be rotated at any time. It is convenient for multiple detections of the external connecting sleeve assembly of the shock absorber assembly.

[0013] Further, the fixing assembly part includes a cylinder mounting seat, a cylinder, a fixing member, a first locking member and a cylinder support plate, the cylinder support plate is detachably mounted on the bottom plate by bolts, two first sliding grooves are provided on the cylinder support plate, the cylinder mounting seat is slidably arranged in the two first sliding grooves of the cylinder support plate, the cylinder mounting seat is locked on the cylinder support plate by the first locking member, the cylinder is arranged on the cylinder mounting seat, a fixing member is arranged at the output end of the cylinder, and the cylinder is electrically connected to the controller;

[0014] The first sensing device includes a first sensor and a first sensing wire, the first sensor is fixedly arranged on the cylinder mounting seat, one end of the first sensing wire is electrically connected to the first sensor, and the other end of the first sensing wire is electrically connected to the controller;

[0015] The first movable component part includes a positioning block, an opening positioning mounting plate, a first sliding block, a first limiting block and a slide rail fixing block. The bottom of the opening positioning mounting plate is installed on the first sliding block. The positioning block is arranged on the upper end of the opening positioning mounting plate close to the side of the liquid storage cylinder height detection plate. One end of the first limiting block is connected to the slide rail fixing block. The fixing piece can be inserted into the first light hole of the slide rail fixing block. The first limiting block is detachably installed on the bottom surface of the opening positioning mounting plate. The first movable component part can slide between the limiting ring and the fixing piece.

[0016] The beneficial effect of adopting the above further scheme is that the first slider drives the open positioning mounting plate to move toward the bracket opening of the shock absorber assembly, and slides the positioning block into the bracket opening of the shock absorber assembly, so that the positioning block is clamped in the bracket opening of the shock absorber assembly and forms a circumferential fixation for the shock absorber assembly, so that the shock absorber assembly cannot rotate axially.

[0017] Furthermore, the liquid storage cylinder height detection plate is detachably mounted on the guide rail and is located between the second slider and the first slider. A first V-shaped groove is provided at the upper end of the liquid storage cylinder height detection plate, and a friction member is provided in the first V-shaped groove.

[0018] The beneficial effect of adopting the above further scheme is that the liquid storage cylinder of the shock absorber assembly is placed in the first V-shaped groove of the liquid storage cylinder height detection plate, and the friction force of the contact surface between the shock absorber assembly and the liquid storage cylinder height detection plate is increased by the friction member arranged in the first V-shaped groove, thereby reducing the axial rotation of the shock absorber assembly and increasing the protection of the liquid storage cylinder to avoid damage to the liquid storage cylinder.

[0019] Furthermore, the third sensing device includes a sensor bracket, a third sensor and a third sensing line. The bottom of the sensor bracket is installed on the top of the base plate and is located close to the upper spring disk of the shock absorber assembly. The third sensor is installed at the upper end of the sensor bracket and the third sensor is facing the upper spring disk of the shock absorber assembly. One end of the third sensing line is electrically connected to the third sensor, and the other end is electrically connected to the controller.

[0020] The beneficial effect of adopting the above further solution is that the liquid storage cylinder of the shock absorber assembly is placed in the first V-shaped groove of the liquid storage cylinder height detection plate, and the shock absorber assembly is clamped in the first V-shaped groove. At the same time, the opening of the bracket of the shock absorber assembly is upward, and the upper spring disk of the shock absorber assembly is located above the third sensor, so that the third sensor senses the position of the upper spring disk of the shock absorber assembly, forming the first induction positioning.

[0021] Furthermore, the external connecting sleeve detection component also includes a second fixed component part and a second movable component part, the second fixed component part is detachably mounted on the bottom plate, the second movable component part is detachably mounted on the second slider, and the second movable component part is movable relative to the second fixed component part.

[0022] The beneficial effect of adopting the above further solution is that the second fixing assembly part and the first fixing assembly part respectively clamp the piston rod screw head and the bracket opening of the shock absorber assembly, and the liquid storage cylinder at the bottom of the shock absorber assembly is clamped by the liquid storage cylinder height detection plate, so that the shock absorber assembly cannot be rotated and cannot be taken out. The angle of the outer connecting sleeve assembly of the shock absorber assembly is detected by moving the second moving assembly part.

[0023] Further, the second fixed assembly part includes a proximity switch support plate, a piston rod screw support column and a piston rod screw support plate, the proximity switch support plate and the piston rod screw support plate can be detachably mounted on one end of the bottom plate having a second slider, the proximity switch support plate is provided with a second sliding groove, one end of the piston rod screw support column is fixedly mounted on the upper end of the piston rod screw support plate, and a second V-shaped groove is provided above the other end;

[0024] The second sensing device includes a sensor mounting seat, a second locking member, a second sensor and a second sensing wire. The sensor mounting seat is slidably disposed in the second sliding groove. The sensor mounting seat is locked on the proximity switch support plate through the second locking member. The second sensor is fixedly mounted on the sensor mounting seat. One end of the second sensing wire is electrically connected to the second sensor, and the other end is electrically connected to the controller.

[0025] The second movable component part includes an external connecting sleeve bolt angle detection plate, a second limit block and a second sliding block. The bottom of the external connecting sleeve bolt angle detection plate is detachably mounted on the second sliding block. The second limit block is detachably mounted on the bottom surface of the external connecting sleeve bolt angle detection plate. A through hole and three second light holes are opened around the through hole in the center of the external connecting sleeve bolt angle detection plate. One end of the piston rod screw support column can pass through the through hole. The second movable component part can slide between the piston rod screw support plate and the sensor mounting seat.

[0026] The beneficial effect of adopting the above further scheme is that when the second fixing component part and the first fixing component part respectively clamp the piston rod screw head and the bracket opening of the shock absorber assembly, and the liquid storage cylinder at the bottom of the shock absorber assembly is clamped by the liquid storage cylinder height detection plate, the shock absorber assembly is axially and circumferentially fixed and cannot be removed. At this time, the outer connecting sleeve assembly of the shock absorber assembly is located in a through hole provided in the center of the outer connecting sleeve bolt angle detection plate. At this time, the surface of the outer connecting sleeve assembly of the shock absorber assembly does not directly contact the detection tool, so that the outer connecting sleeve assembly of the shock absorber assembly can rotate in mid-air.

[0027] Then, the angle of the external connecting sleeve assembly of the shock absorber assembly is detected by moving the second moving assembly part. When the angle of the external connecting sleeve assembly of the shock absorber assembly is correct, and the bolts of the external connecting sleeve assembly of the shock absorber assembly pass through the three second light holes opened on the external connecting sleeve bolt angle detection plate, the second limit block moves to the second sensor, so that the second sensor can sense the position of the second limit block, indicating that this shock absorber assembly is qualified. When the angle of the external connecting sleeve assembly of the shock absorber assembly is incorrect, and the bolts of the external connecting sleeve assembly of the shock absorber assembly cannot pass through the three second light holes opened on the external connecting sleeve bolt angle detection plate, the second sensor cannot sense the position of the second limit block, indicating that the angle of the external connecting sleeve bolt of this shock absorber assembly is unqualified. At this time, the external connecting sleeve assembly of the shock absorber assembly is rotated, and the bolt angle of the external connecting sleeve is adjusted, so that the angle of the external connecting sleeve bolt is correct, and the external connecting sleeve bolt corresponds to the three second light holes opened on the external connecting sleeve bolt angle detection plate, so that the external connecting sleeve bolt can pass through the three second light holes. The outer connecting sleeve component of the rotating shock absorber assembly can be rotated and adjusted multiple times until the outer connecting sleeve bolt can pass through the three second light holes and the second sensor can sense the position of the second limit block, indicating that this shock absorber assembly is qualified, thereby preventing the shock absorber assembly from flowing out due to unqualified angles of the outer connecting sleeve bolts.

[0028] Furthermore, the controller is installed on a workbench.

[0029] The beneficial effect of adopting the above further solution is that the controller is installed on the workbench, which facilitates the controller to control the first sensor, the second sensor and the third sensor to perform sensing control on the shock absorber assembly.

[0030] On the other hand, a method for detecting the angle of an outer connecting sleeve component of a shock absorber assembly is provided, based on a measuring tool for detecting the angle of an outer connecting sleeve component of the shock absorber assembly, and the detection method is as follows:

[0031] S1: Place the shock absorber assembly on the testing gauge, with the outer sleeve assembly side facing the outer sleeve bolt angle detection plate, and the bracket side facing the open positioning mounting plate;

[0032] S2: The piston rod screw head is placed in the second V-shaped groove of the piston rod screw support column, the screw end face is tightly against the end face of the second V-shaped groove, the liquid storage cylinder is placed on the liquid storage cylinder height detection plate, and the bracket opening faces upward;

[0033] S3: The third sensor is facing the upper spring plate of the shock absorber assembly, and the third sensor receives a signal;

[0034] S4: Slide the positioning block into the bracket opening, and the opening positioning mounting plate moves to a predetermined position;

[0035] S5: The first sensor and the third sensor respectively sense the position of the first limit block and the position of the upper spring plate of the shock absorber assembly, and send signals to the controller;

[0036] S6: The controller sends a signal to the cylinder, and the cylinder moves to drive the fixing member to pop out, and the fixing member is inserted into the first light hole of the slide rail fixing block;

[0037] S7: Move the external connection sleeve bolt angle detection plate;

[0038] S8: The angle of the external connecting sleeve assembly of the shock absorber assembly is incorrect, and the bolts on the external connecting sleeve assembly cannot be inserted into the three second light holes corresponding to the external connecting sleeve bolt angle detection plate;

[0039] S9: Rotate the angle of the external connecting sleeve assembly of the shock absorber assembly so that the bolt angles on the external connecting sleeve assembly correspond to the three second light holes on the external connecting sleeve bolt angle detection plate;

[0040] S10: If the bolts on the external connecting sleeve assembly still cannot be inserted into the three second light holes corresponding to the external connecting sleeve bolt angle detection plate, continue to rotate the angle of the external connecting sleeve assembly of the shock absorber assembly;

[0041] S11: until the angle of the external connecting sleeve assembly of the shock absorber assembly is correct, and the bolts on the external connecting sleeve assembly can be inserted into the three second light holes corresponding to the external connecting sleeve bolt angle detection plate;

[0042] S12: The external connection sleeve bolt angle detection plate moves to a predetermined position;

[0043] S13: The second sensor senses the second limit block and transmits a signal to the controller;

[0044] S14: The controller sends a signal to the cylinder, the output end of the cylinder is retracted, and the fixing member is driven to withdraw from the first light hole of the slide rail fixing block;

[0045] S15: The operator slides the movable opening positioning installation plate toward the limit ring, and at the same time slides the outer connection sleeve bolt angle detection plate toward the piston rod screw support plate;

[0046] S16: The operator takes out the shock absorber assembly.

[0047] The beneficial effect of adopting the above further scheme is that, since the contact points between the detection gauge and the shock absorber assembly are the oil storage cylinder and the piston rod screw, the detection gauge does not directly contact the external connection sleeve assembly. Therefore, the external connection sleeve assembly can rotate freely. If the angle is found to be unqualified during detection, it can be directly rotated quickly on the detection gauge, and the angle of the external connection sleeve assembly can be adjusted to the corresponding angle of the piston rod screw support column to continue detection, which is convenient for adjustment. During detection, the liquid storage cylinder of the shock absorber assembly is placed in the first V-shaped groove of the liquid storage cylinder height detection plate, the piston rod screw head of the shock absorber assembly is clamped in the second V-shaped groove, and the bracket opening of the shock absorber assembly is clamped by the positioning block. Then, the cylinder will push the fixing member to insert into the first light hole of the slide rail fixing block, so that the shock absorber assembly is restricted up, down, left, and right, and cannot be taken out. The shock absorber assembly is sensed and positioned by the first sensor and the third sensor.

[0048] Then, move the external connecting sleeve bolt angle detection plate so that the external connecting sleeve bolt angle detection plate moves toward the external connecting sleeve component of the shock absorber assembly, so that the bolts of the external connecting sleeve component can be inserted into the three second light holes opened on the external connecting sleeve bolt angle detection plate. After the test is qualified, the cylinder drives the fixing to automatically withdraw, the shock absorber assembly restriction is released, and the shock absorber assembly can be taken out again to prevent the outflow of unqualified products with angles. Such a structure is simple, fast and convenient to operate. When operating, the operator only needs to place the shock absorber assembly on the detection gauge and pull the detection plates on the left and right sides of the slide rail to the specified position. If the bolts on the external connecting sleeve assembly can pass through the second light holes on the external connecting sleeve bolt angle detection plate, it is qualified, and if they cannot pass through, it is unqualified. It is simple and easy to use and the operation is effortless. BRIEF DESCRIPTION OF THE DRAWINGS

A first V-shaped groove 81 is provided at the upper end of the liquid storage cylinder height detection plate 8 , and a friction member is provided in the first V-shaped groove 81 .

[0071] Specifically, the liquid storage cylinder of the shock absorber assembly is placed in the first V-shaped groove 81 of the liquid storage cylinder height detection plate 8, and the friction between the shock absorber assembly and the liquid storage cylinder height detection plate 8 is increased by the friction member arranged in the first V-shaped groove 81, thereby reducing the axial rotation of the shock absorber assembly and increasing the protection of the liquid storage cylinder to avoid damage to the liquid storage cylinder. In this embodiment, the friction member is a nylon block, and alternatively, the friction member can also be made of other materials with friction.

One end of the third sensing line 10 is electrically connected to the third sensor 11, and the other end is electrically connected to the controller 30.

[0073] Specifically, the liquid storage cylinder of the shock absorber assembly is placed in the first V-shaped groove 81 of the liquid storage cylinder height detection plate 8, and the shock absorber assembly is clamped in the first V-shaped groove 81. At the same time, the bracket opening of the shock absorber assembly is upward, and the upper spring disk of the shock absorber assembly is located above the third sensor 11, so that the third sensor 11 senses the upper spring disk of the shock absorber assembly, forming the first sensing positioning.

[0074] like Figure 1-6 As shown, the external connecting sleeve detection assembly also includes a second fixed assembly part and a second movable assembly part. The second fixed assembly part is detachably mounted on the bottom plate 29, and the second movable assembly part is detachably mounted on the second slider 22. The second movable assembly part is movable relative to the second fixed assembly part.

[0075] Specifically, the piston rod screw head and the bracket opening of the shock absorber assembly are respectively clamped by the second fixing assembly part and the first fixing assembly part, and the liquid storage cylinder at the bottom of the shock absorber assembly is clamped by the liquid storage cylinder height detection plate 8, so that the shock absorber assembly cannot be rotated and cannot be taken out. The angle of the external connection sleeve assembly of the shock absorber assembly is detected by moving the second moving assembly part.

[0076] like Figure 1-6 As shown, the second fixed component part includes a proximity switch support plate 13, a piston rod screw support column 18 and a piston rod screw support plate 19. Both the proximity switch support plate 13 and the piston rod screw support plate 19 can be detachably mounted on one end of the bottom plate 29 having a second slider 22. The proximity switch support plate 13 is provided with a second sliding groove 131. One end of the piston rod screw support column 18 is fixedly mounted on the upper end of the piston rod screw support plate 19, and a second V-shaped groove 181 is provided above the other end.

[0077] The second sensing device includes a sensor mounting seat 14, a second locking member 15, a second sensor 16 and a second sensing line 12. The sensor mounting seat 14 is slidably disposed in the second sliding groove 131. The sensor mounting seat 14 is locked on the proximity switch support plate 13 by the second locking member 15. The second sensor 16 is fixedly mounted on the sensor mounting seat 14. One end of the second sensing line 12 is electrically connected to the second sensor 16, and the other end is electrically connected to the controller 30.

[0078] The second movable component part includes an external connecting sleeve bolt angle detection plate 17, a second limit block 21 and a second slider 22. The bottom of the external connecting sleeve bolt angle detection plate 17 is detachably mounted on the second slider 22. The second limit block 21 is detachably mounted on the bottom surface of the external connecting sleeve bolt angle detection plate 17. A through hole 171 and three second light holes 172 are opened around the through hole 171 in the center of the external connecting sleeve bolt angle detection plate 17. One end of the piston rod screw support column 18 can pass through the through hole 171. The second movable component part can slide between the piston rod screw support plate 19 and the sensor mounting seat 14.

[0079] Specifically, when the second fixing assembly and the first fixing assembly respectively clamp the piston rod screw head and the bracket opening of the shock absorber assembly, and the liquid storage cylinder at the bottom of the shock absorber assembly is clamped by the liquid storage cylinder height detection plate 8, the shock absorber assembly is fixed axially and circumferentially and cannot be removed. At this time, the outer connecting sleeve assembly of the shock absorber assembly is located in a through hole 171 provided in the center of the outer connecting sleeve bolt angle detection plate 17. At this time, the surface of the outer connecting sleeve assembly of the shock absorber assembly does not directly contact the detection tool, so that the outer connecting sleeve assembly of the shock absorber assembly can rotate in mid-air.

[0080] Then, the angle of the external connecting sleeve assembly of the shock absorber assembly is detected by moving the second moving component. When the angle of the external connecting sleeve assembly of the shock absorber assembly is correct, and the bolts of the external connecting sleeve assembly of the shock absorber assembly pass through the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, the second limit block 21 moves to the second sensor 16, so that the second sensor 16 can sense the position of the second limit block 21, indicating that this shock absorber assembly is qualified. When the angle of the external connecting sleeve assembly of the shock absorber assembly is incorrect, and the bolts of the external connecting sleeve assembly of the shock absorber assembly cannot pass through the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, the second sensor 16 cannot sense the position of the second limit block 21, indicating that the angle of the external connecting sleeve bolt of this shock absorber assembly is unqualified. At this time, the external connecting sleeve component of the shock absorber assembly is rotated to adjust the bolt angle of the external connecting sleeve so that the external connecting sleeve bolt angle is correct, and the external connecting sleeve bolt corresponds to the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, so that the external connecting sleeve bolt can pass through the three second light holes 172. The external connecting sleeve component of the shock absorber assembly can be rotated and adjusted multiple times until the external connecting sleeve bolt can pass through the three second light holes 172, and the second sensor 16 can sense the position of the second limit block 21, indicating that this shock absorber assembly is qualified, and avoiding the shock absorber assembly from flowing out due to the unqualified external connecting sleeve bolt angle. In this embodiment, loosening the second locking member 15 can make the sensor mounting seat 14 slide freely in the second sliding groove 131 opened by the proximity switch support plate 13, and tightening it can be fixed. In this embodiment, the second locking member 15 is a screw, and alternatively, the second locking member 15 can also be other components with a locking function.

[0081] like Figure 1-6 As shown, the controller 30 is installed on a workbench.

[0082] Specifically, the controller 30 is installed on a workbench, so that the controller 30 can control the first sensor 5, the second sensor 16, the third sensor 11 and the cylinder 2 to control the shock absorber assembly.

[0083] The beneficial effect of this embodiment is that since the contact points between the detection gauge and the shock absorber assembly are the oil storage cylinder and the piston rod screw, the detection gauge does not directly contact the external connection sleeve assembly, so the external connection sleeve assembly can rotate freely. If the angle is found to be unqualified during detection, it can be directly rotated quickly on the detection gauge, and the angle of the external connection sleeve assembly can be adjusted to the corresponding angle to continue detection, and the adjustment is convenient. During detection, the cylinder 2 will push the fixing member 3 to insert into the first light hole 271 of the slide rail fixing block 27, so that the shock absorber assembly is restricted up and down and left and right and cannot be taken out. After the detection is qualified, the cylinder 2 drives the fixing member 3 to automatically withdraw, the shock absorber assembly restriction is released, and the shock absorber assembly can be taken out again to avoid the outflow of unqualified angle products. Such a structure is simple, quick and convenient to operate. When operating, the operator only needs to place the shock absorber assembly on the detection gauge and pull the detection plates on the left and right sides of the slide rail to the specified position. If the bolts on the external connecting sleeve assembly can pass through the second light hole 172 on the external connecting sleeve bolt angle detection plate 17, it is qualified; if they cannot pass through, it is unqualified. It is simple and easy to use and the operation is effortless.

[0084] The working process of this embodiment is as follows: the shock absorber assembly is placed on the detection gauge, the piston rod screw head of the shock absorber assembly is placed on the external connection sleeve detection assembly, the bracket opening of the shock absorber assembly is placed on the bracket opening detection assembly, and the liquid storage cylinder at the bottom of the shock absorber assembly is placed on the liquid storage cylinder height detection plate 8. During the detection, the first slider 25 drives the opening positioning mounting plate 24 to move toward the bracket opening of the shock absorber assembly, and slides the positioning block 23 into the bracket opening of the shock absorber assembly, and the positioning block 23 is clamped in the bracket opening of the shock absorber assembly. The first sensor 5 senses the position of the first limit block 26 and sends a signal to the controller 30, and the controller 30 controls the output end of the cylinder 2 to output, and the output end of the cylinder 2 drives the fixing member 3 to output at the same time, and inserts the fixing member 3 into the first light hole 271 of the slide rail fixing block 27, and the shock absorber assembly is fixed by the insertion connection of the fixing member 3 and the slide rail fixing block 27.

[0085] Then, the angle of the external connecting sleeve assembly of the shock absorber assembly is detected by moving the external connecting sleeve bolt angle detection plate 17. When the angle of the external connecting sleeve assembly of the shock absorber assembly is correct and the bolts of the external connecting sleeve assembly of the shock absorber assembly pass through the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, the second limit block 21 moves to the second sensor 16, so that the second sensor 16 can sense the position of the second limit block 21, indicating that the shock absorber assembly is qualified.

[0086] When the angle of the external connecting sleeve component of the shock absorber assembly is incorrect, and the bolts of the external connecting sleeve component of the shock absorber assembly cannot pass through the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, the second sensor 16 cannot sense the position of the second limit block 21, indicating that the angle of the external connecting sleeve bolt of this shock absorber assembly is unqualified. At this time, the external connecting sleeve component of the shock absorber assembly is rotated to adjust the bolt angle of the external connecting sleeve so that the angle of the external connecting sleeve bolt is correct, and the external connecting sleeve bolt corresponds to the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, so that the external connecting sleeve bolt can pass through the three second light holes 172. The external connecting sleeve component of the rotating shock absorber assembly can be rotated and adjusted multiple times until the external connecting sleeve bolt can pass through the three second light holes 172, and the second sensor 16 can sense the position of the second limit block 21, indicating that this shock absorber assembly is qualified.

[0087] After the shock absorber assembly is qualified, the controller 30 controls the output end of the cylinder 2 to be recovered, and the output end of the cylinder 2 drives the fixing member 3 to be recovered at the same time, and the fixing member 3 is withdrawn from the first light hole 271 of the slide rail fixing block 27. Then, the opening positioning mounting plate 24 is moved to the position of the limit ring 28 and stops moving. At the same time, the outer connecting sleeve bolt angle detection plate 17 is slid toward the piston rod screw support plate 19. The restriction of the shock absorber assembly is released, and the shock absorber assembly can be taken out again.

[0091] S2: The piston rod screw head is placed in the second V-shaped groove 181 of the piston rod screw support column 18, the screw end face is tightly against the end face of the second V-shaped groove 181, and the liquid storage cylinder is placed on the liquid storage cylinder height detection plate 8, with the bracket opening facing upward;

[0092] S3: The third sensor 11 faces the upper spring plate of the shock absorber assembly, and the third sensor 11 receives a signal;

[0093] S4: Slide the positioning block 23 into the bracket opening, and move the opening positioning mounting plate 24 to a predetermined position;

[0094] S5: The first sensor 5 and the third sensor 11 sense the position of the first limit block 26 and the position of the upper spring plate of the shock absorber assembly respectively, and send signals to the controller 30;

[0095] S6: The controller 30 sends a signal to the cylinder 2, and the cylinder 2 moves to drive the fixing member 3 to pop out, and the fixing member 3 is inserted into the first light hole 271 of the slide rail fixing block 27;

[0096] S7: Move the external connection sleeve bolt angle detection plate 17;

[0097] S8: The angle of the external connecting sleeve assembly of the shock absorber assembly is incorrect, and the bolts on the external connecting sleeve assembly cannot be inserted into the three second light holes 172 corresponding to the external connecting sleeve bolt angle detection plate 17;

[0098] S9: Rotate the angle of the external connecting sleeve assembly of the shock absorber assembly so that the bolt angles on the external connecting sleeve assembly correspond to the three second light holes 172 on the external connecting sleeve bolt angle detection plate 17;

[0099] S10: If the bolts on the external connecting sleeve assembly still cannot be inserted into the three second light holes 172 corresponding to the external connecting sleeve bolt angle detection plate 17, then continue to rotate the angle of the external connecting sleeve assembly of the shock absorber assembly;

[0100] S11: until the angle of the external connecting sleeve assembly of the shock absorber assembly is correct, and the bolts on the external connecting sleeve assembly can be inserted into the three second light holes 172 corresponding to the external connecting sleeve bolt angle detection plate 17;

[0101] S12: The external connection sleeve bolt angle detection plate 17 moves to a predetermined position;

[0102] S13: the second sensor 16 senses the second limit block 21 and transmits a signal to the controller 30;

[0103] S14: the controller 30 sends a signal to the cylinder 2, the output end of the cylinder 2 is retracted, and the fixing member 3 is driven to withdraw from the first light hole 271 of the slide rail fixing block 27;

[0104] S15: The operator slides the movable opening positioning mounting plate 24 toward the limit ring 28, and at the same time slides the outer connection sleeve bolt angle detection plate 17 toward the piston rod screw support plate 19;

[0105] S16: The operator takes out the shock absorber assembly.

[0106] Testing method for qualified shock absorber:

[0107] The shock absorber assembly is placed on the detection gauge, the piston rod screw head of the shock absorber assembly is placed on the external connection sleeve detection assembly, the bracket opening of the shock absorber assembly is placed on the bracket opening detection assembly, and the liquid storage cylinder at the bottom of the shock absorber assembly is placed on the liquid storage cylinder height detection plate 8. During the detection, the first slider 25 drives the opening positioning mounting plate 24 to move toward the bracket opening of the shock absorber assembly, and slides the positioning block 23 into the bracket opening of the shock absorber assembly, and the positioning block 23 is clamped in the bracket opening of the shock absorber assembly. The first sensor 5 senses the position of the first limit block 26 and sends a signal to the controller 30, which controls the output end of the cylinder 2 to output, and the output end of the cylinder 2 drives the fixing member 3 to output at the same time, and inserts the fixing member 3 into the first light hole 271 of the slide rail fixing block 27, and the shock absorber assembly is fixed by the insertion connection between the fixing member 3 and the slide rail fixing block 27.

[0108] Then, the angle of the external connecting sleeve assembly of the shock absorber assembly is detected by moving the external connecting sleeve bolt angle detection plate 17. When the angle of the external connecting sleeve assembly of the shock absorber assembly is correct and the bolts of the external connecting sleeve assembly of the shock absorber assembly pass through the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, the second limit block 21 moves to the second sensor 16, so that the second sensor 16 can sense the position of the second limit block 21, indicating that the shock absorber assembly is qualified.

[0109] After the shock absorber assembly is qualified, the controller 30 controls the output end of the cylinder 2 to be recovered, and the output end of the cylinder 2 drives the fixing member 3 to be recovered at the same time, and the fixing member 3 is withdrawn from the first light hole 271 of the slide rail fixing block 27. Then, the opening positioning mounting plate 24 is moved to the position of the limit ring 28 and stops moving. At the same time, the outer connecting sleeve bolt angle detection plate 17 is slid toward the piston rod screw support plate 19. The restriction of the shock absorber assembly is released, and the shock absorber assembly can be taken out again.

[0110] Detection method when the shock absorber is unqualified:

[0111] The shock absorber assembly is placed on the detection gauge, the piston rod screw head of the shock absorber assembly is placed on the external connection sleeve detection assembly, the bracket opening of the shock absorber assembly is placed on the bracket opening detection assembly, and the liquid storage cylinder at the bottom of the shock absorber assembly is placed on the liquid storage cylinder height detection plate 8. During the detection, the first slider 25 drives the opening positioning mounting plate 24 to move toward the bracket opening of the shock absorber assembly, and slides the positioning block 23 into the bracket opening of the shock absorber assembly, and the positioning block 23 is clamped in the bracket opening of the shock absorber assembly. The first sensor 5 senses the position of the first limit block 26 and sends a signal to the controller 30, which controls the output end of the cylinder 2 to output, and the output end of the cylinder 2 drives the fixing member 3 to output at the same time, and inserts the fixing member 3 into the first light hole 271 of the slide rail fixing block 27, and the shock absorber assembly is fixed by the insertion connection between the fixing member 3 and the slide rail fixing block 27.

[0112] Then, the angle of the external connecting sleeve assembly of the shock absorber assembly is detected by moving the external connecting sleeve bolt angle detection plate 17. When the angle of the external connecting sleeve assembly of the shock absorber assembly is incorrect, and the bolts of the external connecting sleeve assembly of the shock absorber assembly cannot pass through the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, the second sensor 16 cannot sense the position of the second limit block 21, indicating that the angle of the external connecting sleeve bolt of this shock absorber assembly is unqualified. At this time, the external connecting sleeve assembly of the shock absorber assembly is rotated to adjust the bolt angle of the external connecting sleeve so that the angle of the external connecting sleeve bolt is correct, and the external connecting sleeve bolt corresponds to the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17, so that the external connecting sleeve bolt can pass through the three second light holes 172. The external connecting sleeve assembly of the shock absorber assembly can be rotated and adjusted multiple times until the external connecting sleeve bolt can pass through the three second light holes 172, and the second sensor 16 can sense the position of the second limit block 21, indicating that this shock absorber assembly is qualified.

[0113] After the shock absorber assembly is qualified, the controller 30 controls the output end of the cylinder 2 to be recovered, and the output end of the cylinder 2 drives the fixing member 3 to be recovered at the same time, and the fixing member 3 is withdrawn from the first light hole 271 of the slide rail fixing block 27. Then, the opening positioning mounting plate 24 is moved to the position of the limit ring 28 and stops moving. At the same time, the outer connecting sleeve bolt angle detection plate 17 is slid toward the piston rod screw support plate 19. The restriction of the shock absorber assembly is released, and the shock absorber assembly can be taken out again.

[0114] The beneficial effect of adopting the above scheme is that, since the contact points between the detection gauge and the shock absorber assembly are the oil storage cylinder and the piston rod screw, the detection gauge does not directly contact the external connection sleeve assembly. Therefore, the external connection sleeve assembly can rotate freely. If the angle is found to be unqualified during detection, it can be directly rotated quickly on the detection gauge, and the angle of the external connection sleeve assembly can be adjusted to the corresponding angle of the piston rod screw support column 18 to continue the detection, which is convenient for adjustment. During the detection, the liquid storage cylinder of the shock absorber assembly is placed in the first V-shaped groove 81 of the liquid storage cylinder height detection plate 8, the piston rod screw head of the shock absorber assembly is clamped in the second V-shaped groove 181, and the bracket opening of the shock absorber assembly is clamped by the positioning block 23. Then, the cylinder 2 will push the fixing member 3 to insert into the first light hole 271 of the slide rail fixing block 27, so that the shock absorber assembly is restricted up and down and left and right and cannot be taken out. The shock absorber assembly is sensed and positioned by the first sensor 5 and the third sensor 11.

[0115] Then, move the external connecting sleeve bolt angle detection plate 17 so that the external connecting sleeve bolt angle detection plate 17 moves toward the external connecting sleeve component of the shock absorber assembly, so that the bolts of the external connecting sleeve component can be inserted into the three second light holes 172 opened on the external connecting sleeve bolt angle detection plate 17. After the test is qualified, the cylinder 2 drives the fixing part 3 to automatically withdraw, the shock absorber assembly restriction is released, and the shock absorber assembly can be taken out again to avoid the outflow of unqualified angle products. Such a structure is simple, fast and convenient to operate. When operating, the operator only needs to place the shock absorber assembly on the detection gauge and pull the detection plates on the left and right sides of the slide rail to the specified position. The bolts on the external connecting sleeve assembly can pass through the second light holes 172 on the external connecting sleeve bolt angle detection plate 17, which means they are qualified, and they cannot pass through, which means they are unqualified. It is simple and easy to use, and the operation is effortless.
