Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly technology, and more specifically, to an oiling device for ball pin slots. Background Technology

[0002] The connecting rod is an auxiliary moving part on the car chassis that connects the shock absorber to the stabilizer bar or the frame to the stabilizer bar, and plays the role of transmitting force and torque. The ball joint of the connecting rod is sealed with a dust cover to seal the ball joint structure. The upper end of the dust cover is fixed and held in place by a retaining spring at the contact position with the ball pin. As the car moves, the ball pin will swing and rotate, and the dust cover will twist accordingly. In order to reduce the friction between the small opening of the dust cover and the metal surface of the ball pin and to prevent the small opening of the dust cover from rotating with the ball pin, lubricating oil needs to be applied to the ball pin groove.

[0003] Currently, lubricant is usually applied manually to the groove of the ball joint using a brush. When the ball joint is assembled into the small opening of the dust cover, the lubricant can lubricate the connection. However, manual application cannot guarantee the amount and evenness of the lubricant. Too much lubricant will overflow from the small opening of the dust cover, affecting the product's appearance and increasing processing costs. Too little or uneven application of lubricant will reduce the lubrication effect and fail to reduce friction. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] The following is for reference Figures 1-6 As shown in the illustration, and further explained with reference to specific embodiments, this embodiment provides an oiling device for ball pin slots, referring to... Figure 1As shown, the device includes a positioning seat 1 for fixing the position of the ball pin sleeve, a clamping and rotating mechanism 2 for clamping and driving the ball pin to rotate, and an oil supply mechanism 3 for supplying lubricating oil into the groove of the ball pin. The clamping and rotating mechanism 2 includes a spring collet 21, a limiting cylinder 22 for limiting the position of the spring collet 21, and a rotating assembly 23 for driving the spring collet 21 to rotate. The position of the ball pin rod is fixed by the spring collet 21, and then the position of the ball pin sleeve is fixed by the positioning seat 1. The discharge end of the oil supply mechanism 3 is aligned with the groove of the ball pin and oil is injected into the groove of the ball pin. Then, the rotating assembly 23 drives the spring collet 21 to rotate around its own axis so that the ball pin rotates synchronously, thus enabling the lubricating oil to be evenly adhered in the groove of the ball pin in a circumferential direction.

[0029] Reference Figure 1 , Figure 2 As shown, the oil supply mechanism 3 includes a support frame 31, with a support base 32 connected to one side of the support frame 31. A drive cylinder 33 is mounted on the support base 32, and a mounting base 34 is connected to the piston rod of the drive cylinder 33. An oil injection pump 35 is mounted on the mounting base 34, with the feed end of the oil injection pump 35 facing the groove of the ball pin. After the support frame 31 is adjusted to a predetermined position, the drive cylinder 33 is activated, causing the piston rod of the drive cylinder 33 to extend out of the cylinder barrel. This drives the mounting base 34 to move the oil injection pump 35 towards the ball pin groove, facilitating the injection of lubricating oil into the groove of the ball pin. After the oil injection is completed, the drive cylinder 33 is activated again, causing the piston rod of the drive cylinder 33 to retract into the cylinder barrel. This drives the mounting base 34 to move the oil injection pump 35 a certain distance away from the ball pin, facilitating the removal of the processed ball pin.

[0030] Reference Figure 3As shown, the support frame 31 includes a base 311, on which a vertical support rod 312 is welded vertically. A support block 313 is mounted on the top of the vertical support rod 312. A horizontal support rod 314 is provided on one side of the support block 313. A support seat 32 is fixedly connected to the end of the horizontal support rod 314 away from the support block 313. A vertical hole 3131 is provided on the support block 313 for the vertical support rod 312 to pass through. A vertical opening portion 3132 is provided on one side of the vertical hole 3131, and a first fastening bolt 3133 is provided in the vertical opening portion 3132. The support block 313 can slide or rotate along the length direction of the vertical support rod 312 to adjust the height and direction of the support block 313. After adjustment, tightening the first fastening bolt 3133 will clamp the vertical support rod 312 between the two vertical opening portions 3132, thereby fixing the relative position of the support block 313 and the vertical support rod 312. The support block 313 has a transverse hole 3134 through which a horizontal support rod 314 passes. A transverse opening 3135 is located on one side of the transverse hole 3134, and a second fastening bolt 3136 is installed within the transverse opening 3135. The horizontal support rod 314 can slide or rotate within the support block 313 to adjust the distance between the support seat 32 and the support block 313, or the direction of the support seat 32. After adjustment, tightening the second fastening bolt 3136 clamps the horizontal support rod 314 between the transverse openings 3135 on both sides, thus fixing the relative position of the horizontal support rod 314 and the support block 313. By adjusting the state of the support frame 31, the height and direction of the support seat 32 can be adjusted, allowing the oil supply mechanism 3 to perform oiling operations on the grooves of ball pins of different specifications.

[0031] Reference Figure 1 , Figure 4 As shown, the rotating assembly 23 includes a rotating motor 231. A driving gear 232 is coaxially connected to the output shaft of the rotating motor 231, and a driven gear 233, meshing with the driving gear 232, is coaxially connected to the spring collet 21. After the rod of the ball pin is fixed into the spring collet 21, the rotating motor 231 is started to drive the driving gear 232 to rotate. Under the meshing action of the driving gear 232, the driven gear 233 rotates and drives the spring collet 21 to rotate, thereby causing the rod of the ball pin to rotate around its own axis, so that the grease applied to the slot can be evenly distributed in the slot. A bearing 211 is provided between the limiting cylinder 22 and the spring collet 21. The inner ring of the bearing 211 is interference-fitted with the spring collet 21, and the outer ring of the bearing 211 is interference-fitted with the inner wall of the limiting cylinder 22. During the rotation of the rotating assembly 23, the limiting cylinder 22 supports and limits the spring collet 21. By setting the bearing 211, the friction between the limiting cylinder 22 and the spring collet 21 is reduced, thereby reducing wear.

[0032] Reference Figure 1 , Figure 5As shown, in this embodiment, the positioning seat 1 includes a vertical seat 11 and a horizontal seat 12 disposed on the top of the vertical seat 11. The horizontal seat 12 has a placement groove 121 for inserting the ball joint structure of the car connecting rod. Since both ends of the car connecting rod are equipped with ball joint structures, after the ball joint structure of one end of the car connecting rod is placed into the placement groove 121, when the spring collet 21 is rotated by the rotating component 23, the ball pin sleeve of the ball joint structure at the other end of the car connecting rod will not rotate. Therefore, the lubricating oil applied in the ball pin slot can be evenly distributed on the groove surface.

[0033] Reference Figure 6 As shown, in other embodiments, in addition to the structure described above where a horizontal seat 12 is provided on the vertical seat 11 and a placement groove 121 is formed in the horizontal seat 12, the positioning seat 1 also has clamping bolts 13 provided on both sides of the horizontal seat 12 and on the outer sides of the placement groove 121, with the ends of the clamping bolts 13 extending into the placement groove 121. When it is necessary to position a separate ball pin structure, the ball pin sleeve is placed in the placement groove 121, and then the position of the ball pin sleeve is fixed by the clamping bolts 13. During the rotation of the ball pin, the ball pin sleeve will not rotate with the ball pin.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
