Simultaneously, the uniform coating of lubricant improves the assembly efficiency of the hydraulic press, making it easier to press the bushing into place. A rotating frame and servo motor mounted on the lower end and one side of the lubricating cotton sleeve inside the bushing pressing machine can also rotate the oil reservoir sleeve within the lubricating cotton sleeve to the lower end of the filling port, facilitating convenient filling of lubricating oil into the oil reservoir sleeve.

Description

Technical Field

[0001] This utility model relates to the technical field of bushing pressing equipment, specifically an automatic bushing pressing device for automotive parts. Background Technology

[0002] An automatic bushing press-in device for automotive parts is a device that automatically presses bushings into a control arm. Also known as a bushing press-fitting machine, it uses a hydraulic or pneumatic system to power a press head that applies pressure to the bushing, pressing it into a predetermined position. Automotive bushings, also called automotive suspension bushings or suspension bushings, are located between the vehicle body and the axle, primarily serving to cushion, dampen shocks, and reduce wear. They absorb vibrations transmitted from the road surface, protecting the comfort of passengers and preventing excessive wear on various vehicle components.

[0003] Existing bushing press-fitting machines, such as the automotive rear lower control arm bushing press-fitting device disclosed in publication number CN222221702U, although they can shorten the processing and manufacturing cycle of the bushing press-fitting device while ensuring product quality, quickly adapt to changes in product design structure, meet the sample delivery cycle, and one device can be used to press-fit the left and right front lower control arm bushings, do not automatically, conveniently and evenly lubricate the installation position inside the lower control arm before the bushing is installed inside the lower control arm, resulting in poor installation effect. Therefore, we propose an automatic upper bushing press-fitting device for automotive parts. Utility Model Content

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic upper bushing pressing device for automotive parts.

[0027] Example 1:

[0028] Combination Figure 1-6 As shown, this utility model provides an automatic bushing pressing device for automotive parts, comprising: a bushing pressing machine 100 and a lubrication assembly 200; the bushing pressing machine 100 includes a hydraulic press 101 at its upper and lower ends and a door 102; the lubrication assembly 200 includes a left placement block 201 and a right placement block 202 fixedly installed on both sides of the bushing pressing machine 100, a control arm 203 movably installed on the upper end of the left placement block 201 and the right placement block 202, a bushing 204 movably installed on one side of the control arm 203, a connecting rod 205 movably installed on one side inside the bushing pressing machine 100, and an oil reservoir 204 fixedly installed on the top of the connecting rod 205. 06. Oil holes 207 are arranged at the lower part of the oil storage sleeve 206. A lubricating cotton sleeve 208 is fixedly installed at the outer end of the oil storage sleeve 206. An electric push rod 209 is also fixedly installed on one side of the bushing press machine 100. A rotating frame 210 is movably installed at the outer end of the connecting rod 205. A spring 211 is movably installed at the outer end of the connecting rod 205 at the lower part of the rotating frame 210. A servo motor 212 is fixedly installed on the upper part of one side of the rotating frame 210 and is fixedly installed on the bushing press machine 100. A filling port 213 is also opened through one side of the bushing press machine 100. A positioning ring 214 is fixedly installed on the top of the left placement block 201.

[0029] Specifically, the automatic bushing press-in device for automotive parts is a device that automatically presses bushings into control arms, also known as a bushing press-fitting machine. Before the hydraulic press 101 on the bushing press-fitting machine 100 automatically presses the bushing 204 into the control arm 203, the electric push rod 209 inside the bushing press-fitting machine 100 can move the lubricating cotton sleeve 208 at its top to the installation position of the control arm 203 through the pressing connecting rod 205. This provides automatic and comprehensive lubrication to the installation position in the control arm 203, reducing friction and wear during bushing 204 installation. Simultaneously, the uniform coating of lubricant also improves the assembly efficiency of the hydraulic press 101 on the bushing 204, making it easier to press the bushing 204 into place. The rotating frame 210 and the rotating frame 210 installed on the lower end and one side of the lubricating cotton sleeve 208 inside the bushing press-fitting machine 100... The servo motor 212 can also rotate the oil storage sleeve 206 in the lubrication cotton sleeve 208 by rotating the lubrication cotton sleeve 208, so as to rotate it 90 degrees to the lower end of the filling port 213, thereby facilitating the filling of lubricating oil in the oil storage sleeve 206. The positioning ring 214 fixedly installed on the upper end of the left placement block 201 is mainly used for positioning and installing the control arm 203. The oil hole 207 at the outer end of the oil storage sleeve 206 is mainly used to transport the oil in the oil storage sleeve 206 to the lubrication cotton sleeve 208. The spring 211 installed on the outer end of the connecting rod 205 is mainly used to move the lubrication cotton sleeve 208 back when the electric push rod 209 moves down, so as to reciprocate and evenly lubricate the installation part in the control arm 203. The servo motor 212 on one side of the rotating frame 210 is mainly used for filling the oil storage sleeve 206 on the rotating frame 210 with lubricating oil after rotation.

[0030] Working principle and usage process of this utility model:

[0031] During the press-fitting of bushing 204, the control arm 203 is first positioned and installed on the upper ends of the left placement block 201 and the right placement block 202. After the control arm 203 is positioned and installed, the operator presses the middle of the control arm 203 and starts the electric push rod 209 inside the bushing press-fitting machine 100. After starting, the electric push rod 209 lifts the upper connecting rod 205. The connecting rod 205 compresses the spring 211 and lifts it up, thereby moving the lubricating cotton sleeve 208 at the outer end of the top oil storage sleeve 206 through the left placement block 201 into the control arm 203, thus lubricating the installation part of the bushing 204 inside the control arm 203. The electric push rod 209 moves back and forth. The lubricating cotton sleeve 208 is lowered, and after the mounting part of the bushing 204 inside the control arm 203 is evenly and comprehensively lubricated, the bushing 204 can be placed at the top of the lubrication position. The hydraulic press 101 at the top is then started to press the bushing 204 into the control arm 203, thereby completing the pressing of the bushing 204. If there is a lack of lubricating oil in the lubricating cotton sleeve 208, the servo motor 212 can also be started to rotate the rotating frame 210 and the lubricating cotton sleeve 208 by 90 degrees, thereby rotating the oil storage sleeve 206 in the lubricating cotton sleeve 208 to the lower end of the filling port 213, so that the lubricating oil can be added through the filling port 213.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
