Embodiment 1

[0043] A drilling and chamfering processing line for car door parts, including a special drilling machine 1, a mechanical arm 2, and a special chamfering machine 3; Six drilling jigs 13 are installed at equal angles on the turntable 12; the six drilling jigs 13 correspond to six stations; the bed 11 is sequentially equipped with a feeding frame 14, a drilling pin shaft hole mechanism 15, The first detection mechanism 16, the reaming mechanism 17, the vertical drilling mechanism 18 and the second detection mechanism 19; The hydraulic turntable 12 The hydraulic turntable 12 is a six-degree hydraulic turntable, which rotates 60° each time; the mechanical arm 2 is located at the second detection The corresponding station side of mechanism 19.

[0044] The chamfering machine 3 includes a mounting frame 31, a fixture servo slide 32 fixedly installed on the mounting frame 31, the servo slide 32 includes a slide 321 and a servo motor for controlling the movement of the slide; Corner ...

Embodiment 2

[0067] This embodiment has made the following improvements on the basis of Embodiment 1: an error-proofing mechanism is also installed on the feeding frame 14; the error-proofing mechanism includes a vertically arranged compression cylinder; The pressing block and the inspection mechanism; the inspection mechanism is electrically connected with the controller.

[0068] The inspection mechanism includes a proximity switch fixedly installed at the lower end of the pressing block; the lower end of the proximity switch corresponds to the corresponding position after the workpiece 10 is installed.

[0069] The compression cylinder is connected with the booster air pump through a pipeline and controlled by a pneumatic control system; the proximity switch is electrically connected with the controller.

[0070] Through the anti-error mechanism, it is possible to find out in time whether the workpiece 10 is installed incorrectly and adjust it in time, so as to avoid waste caused by the...

Embodiment 3

[0072] This embodiment has made the following improvements on the basis of Embodiment 1: the upper ends of the two fixed columns 331 are located on the same side and are fixedly connected with side baffles 3314; when the workpiece 10 is installed on the chamfering fixture 33, the One side is against the side baffle 3314 . When the workpiece 10 is installed on the chamfering fixture 33 through the side baffle 3314, it plays an auxiliary positioning role.

Abstract

The invention relates to the field of automobile part manufacturing, and discloses a drilling and chamfering processing line for door parts. The drilling and chamfering processing line includes a drilling special machine, a mechanical arm and a chamfering special machine, the drilling special machine includes a lathe bed, a hydraulic rotary table is installed on the lathe bed, and six drilling clamps are installed on the hydraulic rotary table at the equal angle; the six drilling clamps correspond to six stations; a feeding rack, a drilling pin shaft hole mechanism, a first detection mechanism, a reaming mechanism, a vertical drilling mechanism and a second detection mechanism are successively installed on the positions, corresponding to the stations, of the lathe bed; and the mechanical arm is located on the side, corresponding to the second detection mechanism, of the corresponding station, and the chamfering special machine includes a mounting frame, a clamp servo sliding table fixedly installed on the mounting frame, a vertical chamfering mechanism and two horizontal chamfering mechanisms. Processes are conducted simultaneously, the processing time of workpieces can be shortened, and the processing efficiency is improved; and the left parts and the right parts of the workpieces are judged through a photoelectric switch, a sliding table is moved for positioning, processed workpieces are pushed out through a jacking air cylinder, and chamfering and discharging automation are realized.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a drilling and chamfering processing line for car door parts. Background technique [0002] The door hinge is an important part of the car, which connects the door and the body, and is used to realize the opening and closing of the door, so as to facilitate the entry and exit of the driver and passengers. Automobile door hinges are divided into door parts and body parts. like figure 1 The workpiece 10 shown is an L-shaped door hinge, which is a door part; it includes a vertical part 102 and a mounting part 101 perpendicular to each other; the upper end of the vertical part 102 is cylindrical and a pin hole is formed at the axis 1021; the middle of the installation part 101 is formed with a bottom installation hole 1011; the vertical part 102 is located on one side of the installation part 101, that is, one side in the vertical direction of the vertical part 102 is locate...
