Flexible follow-up overturning manipulator claw suitable for feeding and discharging of pitch-circle clamp

Abstract

The invention discloses a flexible follow-up overturning manipulator claw suitable for feeding and discharging of a pitch-circle clamp. The manipulator claw comprises a support, an air cylinder and aconnecting base, wherein the connecting base is hinged to the support through a second shaft; a base plate is mounted on the connecting base; a connecting plate is mounted on the base plate; a cylinder body of the air cylinder is hinged to the support through a first double-lug annular base, and a piston rod of the air cylinder is hinged to the connecting plate through a second double-lug annularbase; and the base plate is provided with a cylindrical base, one end of the base plate is provided with a connecting disc, the connecting disc seals one end of the base plate, and the base is internally provided with an angular contact ball bearing. The manipulator claw also comprises a shaft sleeve and a first shaft, the shaft sleeve is sleeved with the angular contact ball bearing, one end of the first shaft is sleeved with the shaft sleeve, a clamping air cylinder is installed on the first shaft, and manipulator fingers are arranged on the clamping cylinder. After a workpiece enters the pitch-circle clamp, the workpiece advances in the direction of the helical line of a helical gear, feeding of the pitch-circle clamp at any helical angle can be achieved quickly and conveniently, the cost is low, and the feeding time is extremely short.

Description

technical field [0001] The invention relates to a flexible and movable reversible mechanical claw suitable for loading and unloading pitch circle fixtures, belonging to the technical field of mechanical manufacturing equipment. Background technique [0002] At present, the pitch circle fixture is used to clamp the workpiece after the gear is heated or the inner hole is ground. Due to the particularity of the pitch circle fixture, the traditional method of installing the workpiece for the pitch circle fixture still uses manual loading, which cannot be realized. The manipulator automatically loads and clamps the pitch circle fixture, especially the helical gear is more difficult to realize automatic loading and clamping. At present, there is no flexible manipulator claw device for automatic loading of the pitch circle fixture in China. In order to realize the automatic loading and clamping of manipulators abroad, joint robots are equipped with vision systems and force sensors ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a flexible and reversible manipulator claw suitable for loading and unloading pitch circle fixtures, which fills the gap in China, and aims at the high cost and low efficiency of the automatic feeding method adopted abroad. The structural layout realizes the purpose of automatic loading of the manipulator claws for the pitch circle fixture. This structure has flexibility and follow-up function. After the workpiece enters the pitch circle fixture, it can move forward according to the direction of the helical gear helix, and can be used for any helix angle. Fast, convenient, low-cost, and extremely short loading time for pitch-circle jig loading
