Description

Technical Field

[0001] This utility model relates to the technical field of oil injection equipment for automotive parts, and more specifically to an oil injection module for the neck of a workpiece. Background Technology

[0002] As a core transmission component of the automotive chassis steering system, the ball joint's structural strength and assembly precision directly determine the vehicle's handling performance and driving safety. The main structure of the ball joint consists of a ball seat and a rod body, which are independently machined and then pressed together using appropriate tooling.

[0003] For assembly purposes, the neck of the shaft often needs to be coated with a ring of lubricant before being pressed into the ball seat. Because the neck of the shaft is concave, conventional lubrication equipment has difficulty reaching the neck and circling it. Therefore, lubrication is currently mostly done manually. Obviously, this method is inefficient, and the amount of lubricant applied is difficult to control. If too much is applied, it may overflow after assembly, affecting the use of the shaft. Utility Model Content

[0004] The purpose of this invention is to solve the problem that conventional oiling equipment in the prior art is difficult to reach the neck of the club and circle it, while manual oiling is inefficient and the amount of oil applied is difficult to control. If too much oil is applied, it may overflow after assembly with the ball seat, affecting its use.

[0005] To solve the above problems, this utility model provides a workpiece neck oil injection module, including a bracket, an oil injection pipe, an oil reservoir pump, and a motor. The oil reservoir pump is connected to the upper part of the bracket, and a vertical mounting hole is opened on the lower side of the oil reservoir pump. A receiving hole coaxial with the mounting hole is opened on the lower part of the bracket. The middle part of the oil injection pipe is rotatably connected to the mounting hole. The upper end of the oil injection pipe is sealed and rotatably inserted into the mounting hole. The lower section of the oil injection pipe is bent and forms a C-shape. The output end of the motor acts on the upper section of the oil injection pipe to drive the oil injection pipe to rotate around the vertical axis.

[0006] The above solution involves installing a rotatable oil injection pipe on the support. The pipe is driven to rotate by a motor, and its upper end is sealed and rotatably connected to the mounting hole of the oil reservoir pump. When the workpiece moves below the support, the lower section of the oil injection pipe bends into a C-shape, allowing it to extend to the neck of the workpiece. At this point, the motor drives the oil injection pipe to rotate, and the oil reservoir pump supplies lubricating oil to the pipe, causing the lubricating oil to be discharged from the lower end of the pipe and coat the workpiece. Compared with existing technologies, this solution achieves automated oiling of the workpiece neck with higher efficiency; and by controlling the amount of oil discharged from the oil injection pipe through the oil reservoir pump, stable control of the amount of oil applied to the workpiece is achieved.

[0007] In an improved embodiment, the output end of the motor is provided with a synchronous belt, the upper section of the oil injection pipe is fitted with a transmission wheel, the synchronous belt is wound around the transmission wheel, and the motor drives the rotation of the transmission wheel through the synchronous belt, thereby realizing the power transmission between the motor and the oil injection pipe through the synchronous belt and the transmission wheel.

[0008] In an improved embodiment, the bracket is equipped with a sensor for detecting the rotation angle of the oil injection pipe. By detecting the rotation angle of the oil injection pipe through the sensor, the lower end of the oil injection pipe stops in time after circling the workpiece once, thus avoiding excessive oil application.

[0009] In an improved embodiment, the sensor is an infrared sensor, the oil injection pipe is fitted with an annular trigger plate, the trigger plate has a notch, and the probe of the infrared sensor is set corresponding to the trigger plate, ensuring stable and reliable triggering.

[0010] In an improved embodiment, a vertically arranged base frame is further included, with an adjustment platform on the upper side of the base frame. The adjustment platform is equipped with a linear drive, and the bracket is connected to the output end of the linear drive. The bracket is moved by the linear drive, thereby adjusting the position of the bracket through the linear drive to adapt to different types of workpieces.

[0011] In an improved embodiment, the output end of the linear drive is angled downwards, thereby enabling simultaneous adjustment of the lateral and vertical positions of the support, better adapting to different types of workpieces.

[0012] In an improved embodiment, the linear drive is a pneumatic cylinder, hydraulic cylinder, or electric cylinder, which ensures reliable and stable operation. Attached Figure Description

A receiving hole 11 coaxial with the mounting hole 31 is provided on the lower part of the bracket 1. The middle part of the oil injection pipe 2 is rotatably connected to the mounting hole 31. The upper end of the oil injection pipe 2 is sealed and rotatably inserted into the mounting hole 31. The lower section of the oil injection pipe 2 is bent and forms a C-shape. The output end of the motor 4 acts on the upper section of the oil injection pipe 2 to drive the oil injection pipe 2 to rotate about the vertical axis.

[0022] The above solution involves installing a rotatable oil injection pipe 2 on the support 1. The oil injection pipe 2 is driven to rotate by a motor 4. The upper end of the oil injection pipe 2 is sealed and rotatably inserted into the mounting hole 31 of the oil reservoir pump 3. When the workpiece moves below the support 1, the lower section of the oil injection pipe 2 bends into a C-shape, allowing it to extend to the neck of the workpiece. At this time, the motor 4 drives the oil injection pipe 2 to rotate, and simultaneously, the oil reservoir pump 3 supplies lubricating oil to the oil injection pipe 2, causing the lubricating oil to be discharged from the lower end of the oil injection pipe 2 and applied around the workpiece. Compared with existing technologies, the above solution achieves automated oiling of the workpiece neck with higher efficiency; and by controlling the amount of oil discharged from the oil injection pipe 2 by the oil reservoir pump 3, stable control of the amount of oil applied to the workpiece is achieved.

[0023] In this embodiment, a synchronous belt 41 is provided at the output end of the motor 4, and a transmission wheel 21 is sleeved on the upper section of the oil injection pipe 2. The synchronous belt 41 is wound around the transmission wheel 21, and the motor 4 drives the transmission wheel 21 to rotate through the synchronous belt 41, thereby realizing the power transmission between the motor 4 and the oil injection pipe 2 through the synchronous belt 41 and the transmission wheel 21.

More specifically, in this embodiment, the sensor 5 is an infrared sensor 5. The oil injection pipe 2 is fitted with an annular trigger plate 6, which has a notch. The probe of the infrared sensor 5 is positioned corresponding to the trigger plate 6. The triggering of the infrared sensor 5 is stable and reliable; each time the infrared sensor 5 detects the notch in the trigger plate 6, it indicates that the oil injection pipe 2 has rotated one revolution.

The adjustment platform is equipped with a linear drive 8, and a bracket 1 is connected to the output end of the linear drive 8.
