A quality inspection instrument for motorcycle shock absorber manufacturing

Abstract

This utility model belongs to the field of motorcycle technology, specifically a quality inspection instrument for motorcycle shock absorber processing. It includes a test bench comprising a drive housing, a base, a column, a movable plate, and a fixed plate. The lower end of the column is fixedly mounted on the upper surface of the base. This motorcycle shock absorber processing quality inspection instrument utilizes a cleaning mechanism installed on the surface of the test bench. The cleaning cotton structure within the mechanism contacts the surface of the column, cleaning it and reducing frictional resistance during the movement of the movable plate. This improves the accuracy of the test data. Simultaneously, a spring clip at the upper end of the cleaning cotton compresses it, controlling the contact between the cleaning cotton surface and the column surface. This prevents friction between the cleaning cotton and the column surface when the cleaning mechanism is not in use, thus facilitating the cleaning and maintenance of the shock absorber test bench.

Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a quality inspection instrument for motorcycle shock absorber processing. Background Technology

[0002] Shock absorber test benches test shock absorbers by repeatedly compressing and extending them via a movable end on the bench surface. Most existing shock absorber test benches have columns mounted on their surfaces, and the movable end reciprocates across these columns. However, over time, due to environmental factors and friction between the inner wall of the movable end and the column surface, static charge accumulates on the column surface, making it prone to attracting impurities. This increases the coefficient of friction on the column surface, increasing the running resistance of the movable end of the test bench. This not only increases the workload of the test bench but also reduces testing accuracy, ultimately affecting its usability. Utility Model Content

[0003] To address the technical problem that impurities easily adhere to the surface of existing shock absorber test bench columns, this invention proposes a quality inspection instrument for motorcycle shock absorber processing.

[0004] This utility model proposes a quality inspection instrument for motorcycle shock absorber processing, including a test bench. The test bench includes a drive housing, a base, a column, a movable plate, and a fixed plate. The lower end of the column is fixedly installed on the upper surface of the base. Both ends of the movable plate and both ends of the fixed plate are slidably sleeved on the surface of the column. Cleaning mechanisms are installed on both ends of the movable plate. The cleaning mechanism includes a drive box. The surface of the drive box is fixedly connected to the surface of the movable plate. A cleaning hole is opened on one circumference of the drive box. The drive box is slidably sleeved on the surface of the column through the cleaning hole.

[0005] Preferably, a cleaning ring is rotatably connected to the inner bottom wall of one end of the drive box via a bearing, the column is located inside the cleaning ring, an installation groove is provided on the upper surface of the cleaning ring, and a cleaning cotton is clamped into the inner wall of the installation groove. The cleaning cotton is in the shape of a semi-circular ring.

[0006] The above technical solution utilizes a semi-circular ring-shaped cleaning cotton, which only wraps a portion of the column's surface, facilitating disassembly and maintenance. A cover plate can also be installed on the surface of the drive box, allowing the cleaning cotton to be exposed during disassembly and maintenance.

[0007] Preferably, a transmission gear is fixedly sleeved on the outer surface of the cleaning ring, and a drive gear is rotatably connected to the inner bottom wall of the other end of the drive box through a bearing, with the outer surface of the drive gear meshing with the outer surface of the transmission gear.

[0008] The above technical solution utilizes the transmission between the transmission gear and the drive gear, thereby facilitating the rotation of the cleaning ring inside the transmission gear via the drive gear.

[0009] Preferably, a rotating shaft is rotatably connected to the inner top wall of the drive box. The rotating shaft is composed of two rotating shafts rotatably connected. A connecting rod is fixedly inserted into the upper and lower ends of the rotating shaft. A squeezing rod is slidably connected to the upper surface of the cleaning cotton. A retaining ring is fixedly connected to the upper surface of the squeezing rod. One end of each of the two connecting rods is fixedly connected to the two ends of the retaining ring, and a squeezing ring is fixedly connected to the other end of the connecting rod. The squeezing ring is semi-circular and is located directly above the drive gear.

[0010] The above technical solution utilizes the extension and reset of the retaining spring to drive the squeezing rod, causing the lower end of the squeezing rod to squeeze the surface of the cleaning cotton, thus separating the cleaning cotton from the column and facilitating the use of the column.

[0011] Preferably, the upper surface of the drive box and the surface of the movable plate are provided with insertion holes, a lead screw is slidably inserted into the inner wall of the insertion hole, the inner wall of the drive gear is threaded, the inner wall of the drive gear is threadedly connected to the surface of the lead screw, and an electric push rod is fixedly connected to the surface of the base, the upper surface of the movable end of the electric push rod is fixedly connected to the lower surface of the lead screw.

[0012] The above technical solution utilizes an electric push rod to control the lead screw to insert into the drive box, thereby preventing the lead screw from retracting when not in use, thus avoiding affecting the use of the test bench. Furthermore, a guide groove can be opened on the inner wall of the lower end of the drive gear or the thread tolerance can be adjusted, allowing the lead screw to be freely inserted into or withdrawn from the drive gear.

[0013] Preferably, the drive end of the drive housing drives the bottom plate at the lower end of the movable plate via a rocker arm, and the fixed plate is located directly above the movable plate.

[0014] The above technical solution utilizes a drive mechanism to move the movable plate up and down, thereby facilitating the inspection of shock absorbers installed on the surface of the movable plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] By installing a cleaning mechanism on the surface of the test bench, the cleaning cotton structure in the cleaning mechanism contacts the surface of the column to clean the column surface, reducing the frictional resistance when the movable plate moves on the column surface and improving the accuracy of the test data. At the same time, the cleaning cotton is squeezed by the extension and retraction of the spring at the upper end, thereby controlling the contact between the surface of the cleaning cotton and the surface of the column, thus avoiding friction between the cleaning cotton and the column surface when the cleaning mechanism is not in use. This makes it easy to clean and maintain the shock absorber test bench. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5A quality inspection instrument for motorcycle shock absorber processing includes a test bench, which includes a drive housing 1, a base 2, a column 3, a movable plate 4, and a fixed plate 5. The lower end of the column 3 is fixedly installed on the upper surface of the base 2. Both ends of the movable plate 4 and both ends of the fixed plate 5 are slidably sleeved on the surface of the column 3. Cleaning mechanisms are installed on both ends of the movable plate 4. The cleaning mechanism includes a drive box 6, the surface of which is fixedly connected to the surface of the movable plate 4. A cleaning hole is opened on a ring of the surface of the drive box 6, and the drive box 6 is slidably sleeved on the surface of the column 3 through the cleaning hole.

[0025] To clean the surface of the column 3, a cleaning ring 61 is rotatably connected to the inner bottom wall of one end of the drive box 6 via a bearing. The column 3 is located inside the cleaning ring 61. An installation groove is provided on the upper surface of the cleaning ring 61. A cleaning cotton 62 is inserted into the inner wall of the installation groove. The cleaning cotton 62 is semi-circular in shape. By using the semi-circular shape of the cleaning cotton 62, it can wrap only part of the surface of the column 3, which makes it easier to disassemble and maintain the cleaning cotton 62. A cover plate can also be installed on the surface of the drive box 6 to make it easier to expose the cleaning cotton 62 when disassembling and maintaining it.

[0026] To drive the cleaning ring 61, a transmission gear 63 is fixedly sleeved on the outer surface of the cleaning ring 61. A drive gear 64 is rotatably connected to the inner bottom wall of the other end of the drive box 6 via a bearing. The outer surface of the drive gear 64 meshes with the outer surface of the transmission gear 63. Through the transmission between the transmission gear 63 and the drive gear 64, the cleaning ring 61 inside the transmission gear 63 is easily rotated via the drive gear 64. A rotating shaft 65 is rotatably connected to the inner top wall of the drive box 6. The rotating shaft 65 consists of two rotating shafts rotatably connected. Connecting rods are fixedly inserted into both the upper and lower ends of the rotating shaft 65. A squeezing rod 67 is slidably connected to the upper surface of the connecting rod 66 and the cleaning cotton 62. A retaining spring 68 is fixedly connected to the upper surface of the squeezing rod 67. One end of each of the two connecting rods 66 is fixedly connected to both ends of the retaining spring 68. The other end of the connecting rod 66 is fixedly connected to a squeezing ring 69, which is semi-circular and located directly above the drive gear 64. The extension and reset of the retaining spring 68 drives the squeezing rod 67, causing the lower end of the squeezing rod 67 to squeeze the surface of the cleaning cotton 62, thus separating the cleaning cotton 62 from the column 3 and avoiding obstruction of the use of the column 3.

[0027] To control the use of the cleaning mechanism, insertion holes are provided on the upper surface of the drive box 6 and the surface of the movable plate 4. A lead screw 7 is slidably inserted into the inner wall of the insertion hole. The inner wall of the drive gear 64 is threaded and threaded to the surface of the lead screw 7. An electric push rod 8 is fixedly connected to the surface of the base 2. The upper surface of the movable end of the electric push rod 8 is fixedly connected to the lower surface of the lead screw 7. The electric push rod 8 is used to control the lead screw 7 to be inserted into the drive box 6, thereby preventing the lead screw 7 from retracting through the electric push rod 8 when not in use, thus avoiding affecting the use of the test platform.

[0028] By installing a cleaning mechanism on the surface of the test bench, the cleaning cotton 62 in the cleaning mechanism contacts the surface of the column 3 to clean the surface of the column 3, reducing the frictional resistance of the movable plate 4 when moving on the surface of the column 3 and improving the accuracy of the test data. At the same time, the cleaning cotton 62 is squeezed by the extension and retraction of the retaining spring 68 at the upper end, thereby controlling the contact between the surface of the cleaning cotton 62 and the surface of the column 3, thus avoiding friction between the cleaning cotton 62 and the surface of the column 3 when the cleaning mechanism is not in use. This makes it easy to clean and maintain the shock absorber test bench. A guide groove can also be opened on the inner wall of the lower end of the drive gear 64 or the thread tolerance can be adjusted, so that the lead screw 7 can be freely inserted into or withdrawn from the drive gear 64.

[0029] The drive end of the drive housing 1 drives the bottom plate of the movable plate 4 through the rocker arm. The fixed plate 5 is located directly above the movable plate 4. The drive mechanism drives the movable plate 4 to move up and down, which facilitates the testing of the shock absorbers installed on the surface of the movable plate 4.

[0030] Working principle:

[0031] When cleaning the surface of column 3 is required, the electric push rod 8 is activated, which lifts the lead screw 7 upward. The lead screw 7 is inserted into the drive box 6 and the movable plate 4. The drive gear 64 is threaded onto the surface of the lead screw 7. At the same time, the lead screw 7 pushes the adjacent extrusion ring 69 to separate. The extrusion ring 69 drives the retaining spring 68 to retract through the connecting rod 66. The retraction of the retaining spring 68 causes the extrusion rod 67 to separate from the cleaning cotton 62. The cleaning cotton 62 extends and contacts the surface of column 3. The test platform is activated, which drives the movable plate 4 to move up and down. The movable plate 4 drives the drive box 6 to move up and down on the surface of column 3 and lead screw 7. While the drive gear 64 moves up and down on the surface of lead screw 7, the threads on the surface of lead screw 7 drive the drive gear 64 to rotate. The drive gear 64 drives the cleaning cotton 62 to rotate on the surface of column 3 through the transmission gear 63. The friction between the surface of column 3 and the cleaning cotton 62 removes impurities from the surface of column 3.

[0032] When cleaning is not required, the electric push rod 8 is activated, which drives the lead screw 7 to retract downward. The lead screw 7 is pulled out from the drive box 6 and the movable plate 4, and the drive gear 64 separates from the lead screw 7. At the same time, the lead screw 7 separates from the compression ring 69, and the retaining spring 68 extends and resets. The extension of the retaining spring 68 drives the compression rod 67 to squeeze the inclined surface of the cleaning cotton 62, and the cleaning cotton 62 is compressed and separated from the surface of the column 3.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
