Gearbox shell grabbing manipulator for new-energy automobiles

Abstract

The invention relates to the technical field of gearbox production equipment for new-energy automobiles, in particular to a gearbox shell grabbing manipulator for the new-energy automobiles. The gearbox shell grabbing manipulator comprises a clamping jaw seat, clamping jaws, a threaded shaft, a worm gear, a worm, a worm driving motor, a connecting plate, a servo motor, a ball screw and a screw nut, wherein the clamping jaw seat is provided with a sliding groove, and the clamping jaws slide in the sliding groove; and when the threaded shaft rotates, the two clamping jaws are driven to move oppositely, and the worm gear is engaged with the worm. According to the gearbox shell grabbing manipulator, each clamping jaw is arranged on the clamping jaw seat through a sliding part, so that the resistance is reduced to the minimum when the clamping jaws slide, and quick clamping is achieved; the clamping jaws are arranged to move oppositely after being driven by the threaded shaft, and due to the fact that the threaded engagement force of threaded connection is large, a gearbox shell with a large weight can be clamped; and the driving mode of the threaded shaft enables the moving speed and the stroke of the two clamping jaws to be consistent, so that the clamped gearbox shell is in a balanced state, and the situation that assembly is affected due to shake cannot occur.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle gearbox production equipment, in particular to a grabbing manipulator for a new energy vehicle gearbox case. Background technique [0002] The existing gripping manipulator for the gearbox case of new energy vehicles generally drives the belt pulley to rotate by the motor, and the pulley drives the two jaws to move relative to each other to clamp the gearbox case. This driving method leads to clamping The tight bearing capacity is small, and it cannot be adapted to grabbing gearbox casings of different weights, and the existing grabbing manipulator is not equipped with a lifting device, resulting in different grabbing positions for gearbox casings of different heights, resulting in unreliable gripping. At the same time, there is no manipulator with a lifting device. After the operation is completed, other external equipment or manpower are needed to place the gearbox housing on the turn...
