Description

Technical Field

[0001] This utility model relates to a cleaning device for the surface coating of automotive tie rods, belonging to the field of automotive parts processing technology. Background Technology

[0002] As an important component of the automotive steering system, the tie rod is mainly used to realize the steering function. It is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm and is a key component to ensure that the left and right steering wheels produce the correct movement relationship. The automotive tie rod is a long round rod with a variable diameter.

[0003] After automotive parts manufacturers press the front end of a car tie rod into a hexagonal shape, a certain amount of coating (grease) remains on the circumference of the front end. This residual coating needs to be scraped off before the rod can be shipped. Currently, the main method for cleaning this coating is manual scraping with a brush. The process involves a worker holding the tie rod in one hand and a brush in the other, scraping off the remaining coating. This manual method is not only labor-intensive and inefficient, but also prone to incomplete cleaning due to individual worker differences, resulting in inconsistent cleanliness at the front end of the tie rod. Therefore, an improvement is necessary. Summary of the Invention

[0004] The purpose of this invention is to provide a car tie rod surface coating cleaning device that reduces manual labor, improves cleaning efficiency, and solves the problem of inconsistent cleanliness of the front end of the car tie rod due to individual differences among workers.

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

[0006] A cleaning device for the surface coating of automotive tie rods includes a base plate, a left cleaning roller, a right cleaning roller, a feeding assembly, and a storage assembly. The left and right cleaning rollers are mounted on the base plate at intervals via mounting plates. A left drive motor and a belt connect the base plate on one side of the left cleaning roller, and a right drive motor and a belt connect the base plate on one side of the right cleaning roller. A feeding assembly is mounted on the base plate on one side of the left and right cleaning rollers via guide rails. A storage assembly is installed across a line above one end of the guide rails, and the storage assembly is correspondingly positioned to the feeding assembly.

[0007] The feeding assembly includes a base, a servo motor, a push cylinder, and a pneumatic gripper. The base is slidably connected to the guide rail. The servo motor is mounted on the base via a mounting plate. A rolling wheel is mounted on the drive shaft of the servo motor and contacts the base plate. The push cylinder is mounted on the base, and a pneumatic gripper is fixedly mounted on the piston rod of the push cylinder. The pneumatic gripper corresponds to the gap between the left and right cleaning rollers.

[0008] The described material storage component includes a support base, a material cylinder, a limiting frame, and a limiting mechanism. The support base is in a "7" shape. A material cylinder is installed at one end of the support base. A limiting frame is provided below the material cylinder, and a limiting mechanism is installed on the material cylinder on one side of the limiting frame.

[0009] The described material cylinder is a rectangular body, and a profiling channel corresponding to the outer shape of the vehicle pull rod is provided on the material cylinder.

[0010] The described limiting frame includes a first limiting hook and a second limiting hook. The first limiting hook and the second limiting hook are in the shape of right-angled bent round rods. The first limiting hook and the second limiting hook are installed on the material cylinder with an offset up and down. A limiting flat plate is fixedly installed on the second limiting hook.

[0011] The described limiting mechanism includes a limiting cylinder and a limiting baffle. The limiting cylinder is fixedly installed on the material cylinder through a cylinder mounting seat. A limiting baffle is installed on the piston rod of the limiting cylinder. The cross-section of the limiting baffle is in a "卩" shape. A slot is provided on the material cylinder corresponding to the shorter end of the limiting baffle. The shorter end of the limiting baffle is inserted into the slot in a matching manner. A material discharge port is provided corresponding to the profiling channel of the material cylinder at the longer end of the limiting baffle.

[0012] The beneficial effects of the present utility model compared with the prior art are as follows:

[0013] Through the correspondence between the longer end of the limiting baffle and the profiling channel of the material cylinder, the bottom of the profiling channel of the material cylinder is blocked. Then, the base is controlled to move to directly below the profiling channel of the material cylinder, so that the gap between the jaws of the pneumatic gripper corresponds to the profiling channel. The piston rod of the limiting cylinder is controlled to extend, and the shorter end of the limiting baffle is inserted into the slot to limit the vehicle pull rod in the material cylinder. When the limiting baffle limits the vehicle pull rod in the material cylinder, at this time, the material discharge port at the longer end of the limiting baffle just corresponds to the profiling channel of the material cylinder. Thus, the vehicle pull rod in the material cylinder below the limiting baffle falls downward under its own gravity along the material discharge port. The vehicle pull rod that falls downward is limited by the first limiting hook, the second limiting hook, and the limiting flat plate, so that the vehicle pull rod is located between the jaws of the pneumatic gripper. The pneumatic gripper is controlled to clamp the vehicle pull rod. After the vehicle pull rod is clamped, the base is controlled to move to the gap between the left cleaning roller and the right cleaning roller. The piston rod of the pushing cylinder is controlled to extend, so that the pneumatic gripper drives the vehicle pull rod into the gap between the left cleaning roller and the right cleaning roller. The vehicle pull rod that enters the gap between the left cleaning roller and the right cleaning roller is subjected to the brushing action of the bristles of the left cleaning roller and the right cleaning roller, so as to brush the coating on the front end of the vehicle pull rod clean. Thus, the cleaning operation of the vehicle pull rod coating is completed. The vehicle pull rod surface coating cleaning device effectively reduces the manual labor amount, improves the cleaning work efficiency, and at the same time solves the problem of poor front-end neatness consistency of the vehicle pull rod caused by individual differences of the staff.

[0019] As attached Figure 1-4 As shown

[0020] The automotive tie rod surface coating cleaning device includes a base plate 1, a left cleaning roller 2, a right cleaning roller 3, a feeding assembly, and a storage assembly. The left cleaning roller 2 and the right cleaning roller 3 are spaced apart on the top of the base plate 1. The two ends of the left cleaning roller 2 and the right cleaning roller 3 are movably connected to the assembly plate 4 through a short shaft 5 and a bearing, respectively. The assembly plate 4 is fixedly connected to the base plate 1.

[0021] The left cleaning roller 2 and the right cleaning roller 3 are evenly covered with bristles. The left drive motor 6 is fixedly installed on the bottom plate 1 on one side of the left cleaning roller 2 through the motor mounting bracket. The left drive motor 6 is connected to the short shaft 5 of the left cleaning roller 2 through the driving pulley, the driven pulley and the belt. When working, the left drive motor 6 drives the left cleaning roller 2 to rotate clockwise through the driving pulley, the driven pulley and the belt.

[0022] A right drive motor 7 is fixedly installed on the base plate 1 on one side of the right cleaning roller 3 via a motor mounting bracket. The right drive motor 7 is connected to the short shaft 5 of the right cleaning roller 3 via a drive pulley, a driven pulley, and a belt. During operation, the right drive motor 7 drives the right cleaning roller 3 to rotate counterclockwise via the drive pulley, the driven pulley, and the belt.

[0023] A feeding assembly is mounted on the base plate 1 on one side of the left cleaning roller 2 and the right cleaning roller 3 via a guide rail 8. The feeding assembly includes a base 9, a servo motor 10, a push cylinder 11, and a pneumatic gripper 12. The guide rail 8 is fixedly mounted on the base plate 1. Baffles 13 are respectively provided on the base plate 1 at both ends of the guide rail 8. The base 9 is a rectangular body. The base 9 and the guide rail 8 are slidably connected by a sliding groove. The servo motor 10 is fixedly mounted on the base 9 via a mounting plate. A rolling wheel 14 is fixedly mounted on the drive shaft of the servo motor 10. The rolling wheel 14 contacts the base plate 1. During operation, the corresponding input port can be controlled by a programmable controller (PLCS7-800) to realize the clockwise and counterclockwise rotation of the drive shaft of the servo motor 10. This is the prior art, thereby realizing the movement of the base 9 to the left or right on the slide rail.

[0024] A push cylinder 11 is fixedly mounted on the base 9 via a cylinder mounting bracket. A pneumatic gripper 12 is fixedly mounted on the piston rod of the push cylinder 11. An air compressor is connected to the push cylinder 11 and the pneumatic gripper 12. The gaps between the pneumatic gripper 12 and the left cleaning roller 2 and the right cleaning roller 3 are set accordingly.

[0025] A material storage assembly is installed above one end of the guide rail 8. The material storage assembly includes a support base 15, a material cylinder 16, a limit frame, and a limit mechanism. The support base 15 is shaped like a "7". The material cylinder 16 is mounted on one end of the support base 15. The material cylinder 16 is rectangular. The material cylinder 16 is provided with a contour channel 17 that corresponds to the shape of the car tie rod 25. During operation, the material cylinder 16 can store material in the car tie rod 25 through the contour channel 17.

[0026] A limiting frame is provided below the material cylinder 16. The limiting frame includes a first limiting hook 18 and a second limiting hook 19. The first limiting hook 18 and the second limiting hook 19 are right-angled bent round rods. The first limiting hook 18 and the second limiting hook 19 are installed on the material cylinder 16 with their upper and lower parts staggered. The purpose of this setting is to keep the variable diameter car tie rod 25 flat on the first limiting hook 18 and the second limiting hook 19 so that the pneumatic gripper 12 can grip it. A limiting plate 20 is fixedly installed on the second limiting hook 19. The limiting plate 20 can further assist the car tie rod 25 in keeping it flat on the limiting hook, improve its stability, and enable the pneumatic gripper 12 to grip the car tie rod 25.

[0027] A limiting mechanism is installed on the barrel 16 on one side of the limiting frame. The limiting mechanism includes a limiting cylinder 21 and a limiting baffle 2213. The limiting cylinder 21 is fixedly installed on the barrel 16 through a cylinder mounting seat. A limiting baffle 2213 is installed on the piston rod of the limiting cylinder 21. The cross-section of the limiting baffle 2213 is in the shape of a "卩". A slot 23 is provided on the barrel 16 corresponding to the shorter end of the limiting baffle 2213. The shorter end of the limiting baffle 2213 is inserted and fitted with the slot 23. During operation, when the shorter end of the limiting baffle 2213 is inserted into the slot 23, the vehicle tie rod 25 in the barrel 16 can be limited.

[0028] A material discharge port 24 is provided corresponding to the longer end of the limiting baffle 2213 and the profiling channel 17 of the barrel 16. During operation, when the limiting baffle 2213 limits the vehicle tie rod 25 in the barrel 16, at this time, the material discharge port 24 opened at the longer end of the limiting baffle 2213 corresponds to the profiling channel 17 of the barrel 16. Thus, the vehicle tie rod 25 in the barrel 16 below the limiting baffle 2213 falls onto the limiting hook along the material discharge port 24 under its own gravity.

[0029] The vehicle tie rod surface coating cleaning device is provided with a programmable controller (PLCS7 - 800). The programmable controller is electrically connected to the servo motor 10, the pushing cylinder 11, the limiting cylinder 21, and the pneumatic gripper 12. The programmable controller controls the servo motor 10, the pushing cylinder 11, the limiting cylinder 21, and the pneumatic gripper 12 to perform actions in sequence and orderly.

[0030] When using this automotive tie rod surface coating cleaning device, firstly, an appropriate amount of automotive tie rod 25 is placed inside the contour channel 17 of the material cylinder 16. The longer end of the limiting baffle 2213 corresponds to the contour channel 17 of the material cylinder 16, thereby sealing the bottom of the contour channel 17 of the material cylinder 16. Then, the base 9 is moved to directly below the contour channel 17 of the material cylinder 16, so that the gap between the claws of the pneumatic gripper 12 corresponds to the contour channel 17. The piston rod of the control limit cylinder 21 extends, and the shorter end of the limit baffle 2213 inserts into the slot 23, limiting the car pull rod 25 inside the material cylinder 16. After the limit baffle 2213 limits the car pull rod 25 inside the material cylinder 16, the discharge port 24 of the longer end of the limit baffle 2213 corresponds exactly to the contour channel 17 of the material cylinder 16. This causes the car pull rod 25 inside the material cylinder 16 below the limit baffle 2213 to fall downwards along the discharge port 24 under its own weight. The falling car pull rod 25 is limited by the first limit hook 18, the second limit hook 19, and the limit plate 20, thus... The car tie rod 25 is positioned between the claws of the pneumatic gripper 12. The pneumatic gripper 12 is controlled to clamp the car tie rod 25. After the car tie rod 25 is clamped, the base 9 is moved to the gap between the left cleaning roller 2 and the right cleaning roller 3. The piston rod of the push cylinder 11 is controlled to extend, so that the pneumatic gripper 12 drives the car tie rod 25 into the gap between the left cleaning roller 2 and the right cleaning roller 3. The car tie rod 25, which is between the left cleaning roller 2 and the right cleaning roller 3, is brushed clean by the brushing action of the bristles of the left cleaning roller 2 and the right cleaning roller 3, thereby completing the cleaning operation of the coating on the car tie rod 25.
