Technical Field
[0001] The utility model relates to the technical field of oiling equipment, in particular to an oiling device for the inner wall of a limit box hole. Background Art
[0002] The car door needs to work with the limiter when in use to avoid damage or reduced service life caused by excessive opening of the door. Therefore, a corresponding limit box is needed. The holes inside the limit box need to be oiled before assembly to avoid excessive wear of the limit box during use. Therefore, an oiling device is needed.
[0003] The existing oiling device usually needs to be equipped with a positioning fixture to position the limit box, and then the limit box is pushed onto the oiling structure. Through the continuous operation of the oiling structure and the cooperation of the oiling equipment, the mineral oil in the oil barrel is extracted and transported, and finally coated on the empty inner wall of the limit box.
[0004] However, when the existing oiling equipment is working, the output of mineral oil and the coating are generally achieved by a brush head. However, since the inner wall of the hole of the limit box is not smooth but has some grooves, even if the brush head continues to move, it is impossible to completely brush every area of the inner wall of the hole, resulting in poor oiling effect on the inner wall of the hole of the limit box. In view of this, we propose an oiling device for the inner wall of the hole of the limit box. Utility Model Content

[0024] Furthermore, there are two groups of linear motors 2, and the two groups of linear motors 2 are mirror-imaged on the left and right sides of the central axis of the workbench 1. Correspondingly, the clamps 3 matched with the two groups of linear motors 2 move from the left and right sides of the central axis of the workbench 1 toward one side of the fixed seat 4 when the linear motors 2 are started. At the same time, the clamps 3 are configured to be adapted to the size of the limit box, and the side walls of the fixed seat 4 are provided with limit blocks matching the limit box, so that the limit boxes are matched with the limit blocks during the movement of the clamps 3 and finally the limit boxes are fixed to the sides of the fixed seat 4, which is convenient for the later In order to carry out the subsequent oiling work, in addition, the bottom end of the oil inlet valve port 5 arranged on the top of the fixed seat 4 is connected with the top opening of the three-way seat 6, and the top of the oil inlet valve port 5 is connected with the output end of the oil pump through an external pipeline, so that when the oil pump is started, the external mineral oil is input into the interior of the three-way seat 6 through the pipeline and the oil inlet valve port 5.
