Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, specifically to robot grippers. Background Technology
[0002] In existing technologies, engine block cleaning requires the separate handling of the upper and lower cylinder blocks. The upper and lower cylinder blocks need to be clamped in different directions; specifically, the upper cylinder block needs to be clamped axially from its front and rear ends, while the lower cylinder block needs to be clamped from its left and right sides. Traditional solutions using two separate clamping fixtures for the upper and lower cylinder blocks, with different clamping requirements, present the following problems:
[0003] The robot uses two independent grippers to pick up the upper and lower cylinders respectively. The grippers are expensive and the tooling is bulky. In addition, the upper and lower cylinders cannot be transported simultaneously, resulting in low transfer efficiency. Furthermore, the robot requires a quick-change device to switch between the two grippers.
[0004] Currently, there is a lack of a fixture structure that can clamp two different workpieces. Utility Model Content
[0005] This invention provides a robot gripper for bidirectional clamping of two workpieces to solve at least one of the above-mentioned technical problems.

It is characterized in that it further includes a first clamping mechanism, the first clamping mechanism including a mounting frame, a first telescopic cylinder, a guide shaft, a fixed base and a movable seat, and positioning pins are installed on the adjacent sides of the fixed base and the movable seat.
[0007] The mounting frame is connected to the docking end, and the first telescopic cylinder is mounted on the mounting frame. The movable seat is mounted on the telescopic rod of the first telescopic cylinder.

The two jaws of the parallel clamp are detachably connected to the first clamping arm and the second clamping arm, respectively.
[0010] The extension and retraction direction of the parallel clamp is perpendicular to the extension and retraction direction of the first telescopic cylinder.
[0011] This invention achieves clamping of two workpieces in different directions through a first clamping mechanism and a second clamping mechanism. The use of a telescopic cylinder and parallel clamps for clamping actions simplifies the overall space occupied by the control device.
[0012] More preferably, the guide shaft is sequentially connected to the docking end, the mounting bracket, and the fixing base along the length direction;

[0028] The parallel clamp is positioned adjacent to one of the two guide shafts.
[0029] More preferably, a detection plate is connected to the movable seat;
[0030] The mounting bracket is equipped with two proximity switches arranged along the extension and retraction direction of the telescopic cylinder and used to sense the detection plate.
