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 with Figure 4 , the structure of the four-link positioning pin mechanism in this embodiment is set as:
[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] The cylinder rod 21 and the cylinder seat 22 in the pneumatic element are arranged vertically, and the top end of the cylinder rod 21 is pinned in the horizontal hole 11a of the supporting 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 12 is hinged in the center hole 13a with the horizontal pin hole 1...

The invention discloses a four-link locating pin mechanism which is characterized in that a fixed support seat is formed by a support platform and a fixed block fixedly arranged at the bottom of the support platform; the vertical hole of the support platform is internally provided with a guide rod capable of sliding along the axial direction; the top of the guide rod is fixedly connected with a locating pin; the bottom of the guide rod is articulated at the upper end of a rotary connecting rod; a cylinder rod arranged in a pneumatic component is vertical to a cylinder seat; the top of the cylinder rod is connected in the horizontal hole of the support platform by a pin; the front end of a rotating handle is fixedly provided with an adapter block which takes a central hole as a rotating support point; the fixed block is articulated in the central hole by using a rotating pin through a horizontal pin hole; a first hinge joint hole is arranged above the central hole, and a second hinge joint hole is arranged at the front end of the central hole; the bottom of the rotary connecting rod is articulated in the first hinge joint hole by a pin shaft; and the cylinder seat is articulated in the second hinge joint hole by a pin shaft. The four-link locating pin mechanism is simple and reliable in locating structure.
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 ...
