Description

Technical Field

[0001] This utility model relates to a grinding tool for the outer circle of an automotive steering gear lock sleeve, belonging to the field of automotive parts processing technology. Background Technology

[0002] The steering gear lock sleeve is an important component of the automotive steering system, primarily used to position the steering shaft and ensure the stable and reliable operation of the steering system. The steering gear lock sleeve is tubular in shape, with rectangular mounting slots formed on its circumference.

[0003] After machining the assembly slots for automotive steering gear lock sleeves, automotive parts processing companies need to grind their outer circumference to make it smooth for subsequent sales. The current grinding method involves manual hand-held grinding. The grinding process is as follows: the worker holds the steering gear lock sleeve in one hand and the grinding machine in the other, grinding and polishing each steering gear lock sleeve one by one. The above-mentioned manual grinding method is not only labor-intensive and inefficient, but also results in poor consistency of the ground steering gear lock sleeves due to individual differences among workers. Therefore, it is necessary to improve this method. Summary of the Invention

[0004] The purpose of this utility model is to provide a grinding tool for the outer circle of automotive steering gear lock sleeves that reduces manual labor, improves grinding efficiency, and solves the problem of poor consistency after grinding automotive steering gear lock sleeves due to individual differences among workers.

[0005] The technical solution of this utility model is:

[0006] A grinding tool for the outer diameter of an automotive steering gear lock sleeve includes a base plate, a left grinding roller, a right grinding roller, and a guide assembly. The base plate is characterized by: mounting plates spaced apart; the left and right grinding rollers are movably mounted between the mounting plates; a left drive motor is mounted on the mounting plate corresponding to the left grinding roller and connected to it; a right drive motor is mounted on the mounting plate corresponding to the right grinding roller and connected to it; a guide assembly is mounted on the base plate between the left and right grinding rollers; a storage assembly is mounted at one end of the guide assembly; the storage assembly is fixedly connected to the base plate; and a pushing component is mounted on the storage assembly corresponding to the guide assembly.

[0007] The assembly plate has a concave cross-section.

[0008] The guide assembly includes a guide plate, a support plate, and a slide plate. The guide plate has a semi-circular cross-section, and the support plate and slide plate have arc-shaped cross-sections. One end of the guide plate is fixedly connected to one end of the support plate, and the other end of the support plate is fixedly connected to the slide plate at an incline. A support platform is fixedly installed below the support plate.

[0009] The storage assembly includes a base and a storage cylinder. The storage cylinder is fixedly installed on the base. The storage cylinder is a rectangular strip with a storage channel. A clearance hole is provided between the base and the storage cylinder at a position corresponding to the guide assembly.

[0010] The pushing component includes a fixed plate and a horizontal pushing cylinder. The fixed plate has an "L"-shaped rectangular cross section and is fixedly mounted on the storage component. The horizontal pushing cylinder is fixedly installed on the fixed plate, and a push plate is fixedly installed on the piston rod of the horizontal pushing cylinder. The push plate is disc-shaped and is configured to correspond to the clearance hole.

[0011] A limiting arc plate is fixedly installed on one end face of the push plate.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] The automotive steering gear lock sleeve outer diameter grinder uses a left drive motor and a right drive motor to drive the left and right grinding rollers to rotate clockwise. This activates the transverse push cylinder, controlling the piston rod to extend. The piston rod pushes the push plate forward, and as the push plate moves forward, it enters the clearance hole, propelling the automotive steering gear lock sleeve forward. Simultaneously, the limiting arc plate, after entering the clearance hole, limits the movement of the automotive steering gear lock sleeve in the storage channel. The transverse push cylinder is then reset. After the automotive steering gear lock sleeve in the storage channel has filled in the clearance hole, the piston rod of the transverse push cylinder is extended again. This process is repeated, sequentially pushing the automotive steering gear lock sleeves from the clearance hole onto the guide plate. The automotive steering gear lock sleeves are arranged in a "I" shape on the guide plate, and as the automotive steering gear lock sleeves behind the guide plate move forward... The steering gear lock sleeve continuously pushes the front steering gear lock sleeve forward, and the steering gear lock sleeve on the guide plate enters the support plate. The circumference of the steering gear lock sleeve inside the support plate contacts the left and right grinding rollers. Since the left and right grinding rollers rotate clockwise, after they contact the steering gear lock sleeve, they can drive the steering gear lock sleeve to rotate counterclockwise. Since the left and right grinding rollers act on the steering gear lock sleeve at the same time, the steering gear lock sleeve can be smoothly rotated counterclockwise on the support plate, so that its outer circle can be ground by the grinding rollers. This steering gear lock sleeve outer circle grinder effectively reduces manual labor, improves grinding efficiency, and solves the problem of poor consistency of steering gear lock sleeve grinding caused by individual differences of workers.

[0020] As attached Figure 1-5 As shown

[0021] The automotive steering gear lock sleeve outer circle grinder includes a base plate 1, a left grinding roller 2, a right grinding roller 3, and a guide assembly. Two mounting plates 4 are fixedly installed at intervals on the base plate 1. The cross-section of the mounting plates 4 is U-shaped. The left grinding roller 2 and the right grinding roller 3 are movably installed between the two mounting plates 4 through a short shaft 5 and a bearing. A left drive motor 6 is fixedly installed on the mounting plate 4 corresponding to the left grinding roller 2 through a motor mounting seat. The drive shaft of the left drive motor 6 is connected to the short shaft 5 of the left grinding roller 2. During operation, the drive shaft of the left drive motor 6 and the short shaft 5 work together to drive the left grinding roller 2 to rotate clockwise.

[0022] A right drive motor 7 is fixedly mounted on the mounting plate 4 corresponding to the right grinding roller 3 via a motor mounting bracket. The drive shaft of the right drive motor 7 is connected to the short shaft 5 of the right grinding roller 3. During operation, the right grinding roller 3 is driven to rotate clockwise by the cooperation of the drive shaft of the right drive motor 7 and the short shaft 5.

[0023] A guide assembly is installed on the base plate 1 between the left grinding roller 2 and the right grinding roller 3. The guide assembly includes a guide plate 8, a support plate 9 and a slide plate 10. The guide plate 8 has a semi-circular cross section, and the support plate 9 and the slide plate 10 have arc cross sections. One end of the guide plate 8 is fixedly connected to one end of the support plate 9, and the other end of the support plate 9 is fixedly connected to the slide plate 10 at an incline. A support platform 11 is fixedly installed below the support plate 9. The support platform 11 is fixedly installed on the base plate 1. During operation, the support platform 11 is used to support the support plate 9 to ensure the stability of the support plate 9.

[0024] A storage component is installed at one end of the guide assembly. The storage component includes a base 12 and a storage cylinder 13. The base 12 is rectangular and is fixedly installed on the base plate 1. The storage cylinder 13 is fixedly installed at the center of the upper surface of the base 12. The storage cylinder 13 is a rectangular strip and has a storage channel 20. The storage channel 20 is used to store multiple automotive steering gear lock sleeves 19. A clearance hole 14 is provided between the base 12 and the storage cylinder 13 at the position corresponding to the guide assembly. The clearance hole 14 communicates with the storage channel 20 and corresponds to the groove of the guide plate 8 of the guide assembly. During operation, the automotive steering gear lock sleeve 19 can move into the groove of the guide plate 8 through the clearance hole 14.

[0025] A pushing component is installed on the storage component corresponding to the guiding component. The pushing component includes a fixed plate 15 and a horizontal pushing cylinder 16. The fixed plate 15 has an "L"-shaped rectangular cross section and is fixedly installed on the base 12 of the storage component. The horizontal pushing cylinder 16 is fixedly installed on the fixed plate 15. A push plate 17 is fixedly installed on the piston rod of the horizontal pushing cylinder 16. The push plate 17 is disc-shaped and is correspondingly set with the clearance hole 14. When working, the piston rod of the horizontal pushing cylinder 16 extends and pushes the push plate 17 forward. When the push plate 17 moves forward, it can enter the clearance hole 14, thereby pushing the car steering lock sleeve 19 in the clearance hole 14 forward.

[0026] A limiting arc plate 18 is fixedly installed on one end face of the push plate 17. The purpose of this setting is that after the limiting arc plate 18 enters the clearance hole 14, it can limit the car steering lock sleeve 19 in the storage channel 20, so that the push plate 17 can smoothly push the car steering lock sleeve 19 in the clearance hole 14 forward. When the limiting arc plate 18 exits the clearance hole 14, the lowest car steering lock sleeve 19 in the storage channel 20 falls into the clearance hole 14 under its own gravity, forming a replacement in sequence, which facilitates the next push plate 17 to push the car steering lock sleeve 19.

[0027] When the car steering gear lock sleeve outer circle grinder is working, the left drive motor 6 and the right drive motor 7 are started first. The left drive motor 6 drives the left grinding roller 2 to rotate clockwise, and the right drive motor 7 drives the right grinding roller 3 to rotate clockwise. Then, the car steering gear lock sleeve 19 to be ground is aligned with the storage channel 20 with its outer circle, and an appropriate amount of car steering gear lock sleeve 19 is placed into the storage channel 20 in an orderly manner. The car steering gear lock sleeve 19 is arranged vertically from top to bottom in the storage channel 20. The bottom car steering gear lock sleeve 19 enters the clearance hole 14. Finally, a collection box is placed at the end of the slide plate 10.

[0028] After the above preparations are completed, the transverse thrust cylinder 16 is activated, and the piston rod of the transverse thrust cylinder 16 is extended. The piston rod pushes the push plate 17 forward. When the push plate 17 moves forward, it enters the clearance hole 14 and pushes the car steering gear lock sleeve 19 in the clearance hole 14 forward. At the same time, the limiting arc plate 18 enters the clearance hole 14 and can limit the car steering gear lock sleeve 19 in the storage channel 20. The transverse thrust cylinder 16 is then reset, and the car steering gear lock sleeve 19 in the storage channel 20 is pushed forward. 9. After filling in the clearance hole 14, control the piston rod of the transverse thrust cylinder 16 to extend again. Repeat this process to push the car steering gear lock sleeves 19 sequentially from the clearance hole 14 onto the guide plate 8. The car steering gear lock sleeves 19 are arranged in a "I" shape on the guide plate 8. As the rear car steering gear lock sleeves 19 on the guide plate 8 continuously push the front car steering gear lock sleeves 19 forward, the car steering gear lock sleeves 19 on the guide plate 8 enter the support plate 9, and the car steering gear lock sleeves 19 enter the support plate 9. The steering gear lock sleeve 19 contacts the left grinding roller 2 and the right grinding roller 3. Since the left grinding roller 2 and the right grinding roller 3 rotate clockwise, their contact with the steering gear lock sleeve 19 causes it to rotate counterclockwise. Because the left grinding roller 2 and the right grinding roller 3 act simultaneously on the steering gear lock sleeve 19, it can smoothly rotate counterclockwise on the support plate 9, allowing the grinding rollers to grind its outer circumference. The resulting steering gear lock sleeve... The steering gear lock sleeve 19 is pushed by the previous steering gear lock sleeve 19 and moved from the support plate 9 to the slide plate 10. Due to the inclined setting of the slide plate 10, the steering gear lock sleeve 19 slides into the collection frame under its own weight, thereby completing the entire grinding work of the steering gear lock sleeve 19. This steering gear lock sleeve outer circle grinder effectively reduces manual labor and improves grinding efficiency. At the same time, it solves the problem of poor consistency of the grinding of the steering gear lock sleeve 19 due to individual differences of workers.
