Description

A reversible positioning fixture on a multi-station rotary table

technical field

The utility model relates to a positioning fixture, in particular to a reversible positioning fixture on a multi-station rotary table, which is used for automatic assembly.

Background technique

In automatic assembly, the tooling on the multi-station rotary table is generally fixed on the rotary table, but when the function requires it to be able to rotate, it is often electric or pneumatic, but in this case, it is necessary to install a pneumatic slide in the middle of the rotary table. Ring or electric slip ring, the structure is complicated, the price is expensive, and the reliability is average; in view of the above situation, we have developed a mechanical trigger mechanism to realize the flip.

Chinese patent 201110389848.4 discloses an overturn positioning mechanism, which includes: a clamping member, used to clamp the workpiece and drive the workpiece to turn over, which includes two opposite clamping claws, wherein at least one clamping claw is provided with at least two The positioning hole; the positioning member includes a positioning pin, and the positioning pin is operatively inserted into the positioning hole of the at least one clamping claw to stop the rotation of the clamping member. This structure is relatively complicated, and the performance is not good.

Utility model content

The utility model mainly solves the deficiencies in the prior art, and provides a reversible positioning jig on a multi-station rotary table with a compact structure, excellent performance and high reliability.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions:

A reversible positioning fixture on a multi-station rotary table, including a reversing assembly and a jacking and returning assembly, the reversing assembly includes a jig mounting plate and joint bearings, and the two ends of the jig mounting plate are respectively set There is a bearing seat, the bearing seat and the fixture mounting plate are positioned and rotated through the rotating shaft, the rotating shaft at one end is rotationally connected with the upper end of the joint bearing, and a swing arm is arranged between the rotating shaft and the joint bearing;

The jacking and returning assembly includes a return device mounting seat and a guide shaft. The bottom of the return device mounting seat is provided with a return slide plate perpendicular to the return device mounting seat. The return slide plate A return slide rail is provided on the return slide rail, and a linear slider slidingly connected with the return slide rail is provided on the return slide rail. A connecting block is provided on the linear slide block, and the lower end of the guide shaft It is fixedly connected with the connection block, the upper end of the guide shaft is slidably socketed with the mounting seat of the return device, a return spring is provided between the connection block and the guide shaft, and a The jacking cylinder that connects the block phase jacking.

As a preference, the upper part of the clamp mounting plate is provided with a positioning column, the upper part of the return device mounting seat is provided with a positioning connecting column, the connecting block is in the shape of a right angle, and the joint bearing is provided with a Adjust the connecting rod.

Preferably, a connecting piece is provided between the clamp installation plate and the rotating shaft, the connecting piece is fixedly connected with the rotating shaft, and the cross section of the connecting piece is “U” shaped.

The advantages of this structure: solve a kind of reversible tooling on the multi-station rotary table in automatic assembly, simple and reliable structure, and low cost.

The action is as follows: when the rotary table turns to the overturning screwing station, the jacking cylinder moves up, jacks up the connecting block, drives the joint bearing, and thus moves the swing arm to make the rotating shaft rotate, that is, the fixture mounting plate rotates to a certain After the angle is reached, the vertical limit pin is used to limit the position to complete the rotation. When the station work is completed, the jacking cylinder returns, and the connecting block moves down under the action of the return spring to drive the joint bearing, thereby oscillating the swing arm, so that the rotating shaft at the two ends of the fixture seat rotates, that is, the fixture mounting plate rotates , when rotated to the horizontal position, it is limited by the horizontal limit pin.

The utility model provides a reversible positioning jig on a multi-station rotary table, which further improves the intelligent level of a robot, realizes automatic reversing, and has high operation precision.
