Problems solved by technology
In the field of automobile welding and assembly lines, although there are some complete sets of equipment, their cost is high and maintenance costs are high, so they cannot be widely used
On the other hand, in order to improve welding efficiency, there is already a method of welding body-in-white with mixed lines. For this reason, the manual positioning pin mechanism used in the mixed-line welding line is also an indispensable part; but the existing The positioning pin mechanism is manually operated and rigidly connected. This form of structure is complex and the precision is not high. When the manual operation is in place, some of them will automatically fall due to the excessive weight of their own mechanism, so that it cannot guarantee normal operation.

Embodiment Construction
[0021] see figure 1 , image 3 and Figure 4 , the structure of the positioning pin mechanism in this embodiment is set to:
[0022] The support platform 11 and the fixed block 12 fixedly arranged at the bottom of the support platform form a fixed support. One side of the support platform 11 is a horizontal hole 11a, the other side is a vertical hole 11b, and the bottom end of the fixed block 12 is a horizontal pin. In the hole 12a, an axially slidable guide rod 4 is arranged in the vertical hole 11b.
[0023] In this embodiment, the vertical linear drive mechanism is a pneumatic element, the cylinder rod 21 and the cylinder seat 22 in the pneumatic element are vertically arranged, and the top end of the cylinder rod 21 is pinned in the horizontal hole 11a of the support platform.
[0024] The front end of the rotating handle 14 is fixedly provided with a transfer block 13, the transfer block 13 is to take the center hole 13a as the fulcrum of rotation, and the fixed block ...

The invention discloses a positioning pin mechanism, which is characterized by comprising a fixing support consisting of a supporting platform and a fixing block fixedly arranged at the bottom of the supporting platform. A guide rod capable of axially sliding is arranged in a vertical hole of the supporting platform; a positioning pin is fixedly linked at the top end of the guide rod; the bottom end of the guide rod is hinged at the upper end of a rotary connecting rod; a through connection block is fixedly arranged at the front end of a rotary handle; the through connection block uses a center hole as a rotation supporting point; the fixing block is hinged in the center hole through a rotation pin via a horizontal pin hole of the fixing block; a first hinging hole is arranged above the center hole; a second hinging hole is arranged at the front end of the center hole; the bottom end of the rotary connecting rod is hinged in the first hinging hole through a pin shaft; and the top end of a vertically-arranged linear driving mechanism is in pin joint in a horizontal hole of the supporting platform, and the bottom end of the vertically-arranged linear driving mechanism is hinged in the second hinging hole of the through connection block through a lateral lug. The positioning structure provided by the invention is simple and reliable.
Description
technical field [0001] The invention relates to a positioning pin mechanism, which is especially applied on an automobile welding line. Background technique [0002] With the development of modern automobile technology, the automobile manufacturing industry is also accelerating its development towards low labor intensity. Especially in the process of automobile welding, semi-automatic equipment or manual mechanisms are widely used in order to reduce the labor intensity of workers and improve work efficiency for manual loading. In the field of automobile welding and assembly lines, although there are some complete sets of equipment, their cost is high and maintenance costs are high, so they cannot be widely used. On the other hand, in order to improve welding efficiency, there is already a method of welding body-in-white with mixed lines. For this reason, the manual positioning pin mechanism used in the mixed-line welding line is also an indispensable part; but the existing ...
