Description

Self-adaptive pneumatic claw structure

Technical Field

The utility model relates to a pipe fitting centre gripping technical field specifically is a self-adaptation gas claw structure.

Background

Along with the deepening of degree of automation, under the prerequisite of the quality of guaranteeing the product, equipment has carried out large-scale technological transformation, and after the transformation, production efficiency improves, practices thrift the cost simultaneously. There is room for improvement.

The patented technology is based on prior art re-optimization. The prior art is as follows:

as shown in fig. 1, the conventional structure is composed of a first cylinder 1, a second cylinder 2, a gas claw 3, a clamp and related components. The mechanism realizes the following actions: as shown in fig. 1, the workpiece to be processed, the pipe 4, is moved up first (the mechanism is moved up first to ensure the safety of the mechanism, otherwise the pipe directly hits the pipe reducing lower clamp 32 shown in fig. 4, causing damage to the workpiece to be processed and the air jaws), is moved down-moved to move parallel to the upper center of the pipe reducing clamp, and the pipe 4 is placed with the air jaws opened and translated back to the initial position.

The first cylinder 1 controls the up-and-down motion, and the second cylinder 2 controls the forward-and-backward motion in the parallel direction. As shown in fig. 1, when the mechanism works, the first cylinder 1 works after the air claw grasps a workpiece to be processed, the second cylinder 2 and the air claw are pushed to move upwards, and the first cylinder 1 stops working after reaching the upwards moving position (the sensor senses whether the position of the first cylinder is correct); the second cylinder 2 works to push the gas claw to move horizontally, a workpiece to be machined is sent to the position above the circular arc of the pipe reducing lower clamp 32 shown in the figure 4, after the sensor senses that the workpiece to be machined is in place, the piston rod of the first cylinder 1 contracts to move, the workpiece to be machined clamped by the gas claw is made to fall into the circular arc of the pipe reducing lower clamp 32 shown in the figure 4, after the first cylinder 1 moves in place, the pipe reducing upper clamp on the station automatically moves downwards under the driving of the oil cylinder, after the workpiece is in place in press fit with the pipe reducing lower clamp of the station, the gas claw 3 is released, and the second cylinder 2 performs the moving and. This process is one round.

In the process, each position control is to sense the position of the air cylinder through a position sensor and accurately control the action of the air cylinder by using a PLC.

The mechanism has high structural stability, but high cost and low production efficiency.
