BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 is a three-dimensional diagram of the device;

[0015] Figure 2 Interior view of this device with the cover removed;

[0016] Figure 3 This is a three-dimensional diagram of the device from another direction. DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1-3 As shown, a door opening mechanism for an automobile welding adjustment line includes a bracket 1, a cylinder 2, a positioning pin 3, a lifting cylinder 4 and an arc moving mechanism 5. The cylinder is mounted on the bracket, and the piston rod of the cylinder is connected to the arc moving mechanism, driving the arc moving mechanism to move along an arc track 6. The lifting cylinder is mounted on the arc moving mechanism, and the piston rod of the lifting cylinder is connected to the positioning pin, and the positioning pin is used to position the door. The cylinder drives the arc moving mechanism to move on the arc track to simulate the trajectory of opening the door, and the upper positioning pin positions the door through the lifting cylinder, thereby realizing the automatic opening and closing of the door.

[0019] like Figure 2 and Figure 3 As shown, in this device, the arc moving mechanism includes a transverse clamping wheel 51, a longitudinal clamping wheel 52, an upper connecting plate 53, a transverse clamping arm 54 and a longitudinal clamping arm 55. The transverse clamping wheel is fixed to both sides of the upper connecting plate through the transverse clamping arm, and the transverse clamping wheel rolls with the side wall of the arc track. The longitudinal clamping wheel is fixed to both sides of the upper connecting plate through the longitudinal clamping arm. There are two longitudinal clamping wheels on the longitudinal clamping arm, which are clamped on the upper and lower sides of the side of the arc track and roll with it. The arc track is clamped by the transverse clamping wheel and the longitudinal clamping wheel, so that the upper positioning pin can move smoothly along the arc track.

[0020] In order to limit the maximum movement range of the arc-shaped moving mechanism, a stopper 8 is provided at the end of the arc-shaped track.

[0021] In order to protect the internal components, a cover plate 9 is provided on the upper part of the bracket. An arc groove 10 is formed on the cover plate, and the positioning pin passes through the arc groove.

[0022] In the device, the cylinder is mounted on the bracket via a cylinder bracket. For buffering, a pad is provided between the arc track and the bracket.

[0023] In order to better protect the components, the bracket is provided with a partition 11 in the middle, and the arc-shaped moving mechanism and the cylinder are mounted on the partition. Support columns 12 are welded around the partition, and the cover plate is welded on the support columns.

[0024] The cylinder of the component opens, and the running part moves along the track in an arc shape, driving the positioning pin to open a certain angle, so that the front door of the car can be opened, and the worker stands on the support platform to tighten the fender bolts. When the bolts are installed, the cylinder shrinks, and the running part returns to its original position along the track in an arc shape, so that the front door of the car can be automatically closed, the lifting cylinder shrinks, the positioning pin retreats, and the car body flows to the next station.

[0025] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
