Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to a drilling structure of a hinge rotating arm of a rear cover of a vehicle body. Background Art

[0002] Cars generally have trunks, and the rear cover on the trunk needs a pair of hinge devices when it is opened. The function of the rear cover hinge connecting pipe is to support the rear cover of the car, and it is an indispensable spare part for the car. Since the rear cover hinge connecting pipe needs to support the rear cover of the car, its inner side must have a group of connection holes for connecting with the side of the rear cover, and the end side also needs connection holes for connecting with the hinge.

[0003] Chinese patent CN109382536A discloses a drilling device for a hinge rotating arm of a vehicle body rear cover, comprising a frame, a clamping device, a drilling device and a controller; the clamping device comprises a base, a support seat, a positioning block, a support member, a clamping block and a clamping drive device; the base is fixedly arranged on the frame, a guide rail is arranged on the base, and the support seat is driven by a sliding drive device to reciprocate on the guide rail; the upper surface of the support seat is provided with a head and a tail fixing block; each corner of the hinge rotating arm of the vehicle body rear cover is supported by a support member, the support member and the positioning block are fixedly arranged on the support seat, and the positioning blocks are distributed on both sides of the hinge rotating arm of the vehicle body rear cover; the clamping drive device is connected to the clamping block; the drilling device is used for drilling holes in the hinge rotating arm of the vehicle body rear cover, and the controller is electrically connected to the sliding drive device, the clamping drive device and the drilling device. In this patent, the hinge pivot arm of the rear cover of the vehicle body is placed flat on the frame, clamped at both ends by clamping devices, and fixed in the middle by a positioning block. However, since the hinge pivot arm of the rear cover of the vehicle body is placed flat on the frame, there is no force contact between the middle part of the hinge pivot arm of the rear cover of the vehicle body and the positioning block. The disturbance during the hole turning process may cause the middle part of the hinge pivot arm of the rear cover of the vehicle body to vibrate, resulting in reduced processing accuracy.
