Clamping device for off-line detection of motor gearbox of new energy vehicle

Abstract

The invention discloses a clamping device for off-line detection of a motor gearbox of a new energy vehicle. The clamping device comprises a clamping body fixed end part and a clamping body movable end part; the clamping body movable end part comprises a movable seat, movable end clamping units which are arranged on the movable seat, and positioning pin seats which are arranged on the movable seat; positioning pins which are in location fit with technology holes in the gearbox are arranged in the positioning pin seats; the fixed end clamping body part comprises a fixed seat, fixed end clampingunits which are arranged on the fixed seat, and a supporting unit which is arranged on the fixed seat and used for abutting against and supporting the gearbox; after the gearbox is subjected to primary clamping by the movable end clamping units, the clamping body movable end part moves towards the clamping body fixed end part, the gearbox is subjected to secondary clamping by the fixed end clamping units; and after the secondary clamping, the clamping body movable end part returns. Split design is adopted to realize two-stage split clamping, so that a clamping position of the motor gearbox isaccurate and the clamping is more stable.

Description

technical field [0001] The invention relates to the field of off-line test auxiliary facilities for new energy vehicle motor gearboxes, in particular to a clamping device for off-line detection of new energy vehicle motor gearboxes. Background technique [0002] The traditional automobile gearbox relies on the engine to transmit torque and speed, and the speed is relatively low at about 3000r / min, and the casing structure of the gearbox has many clamping surfaces. For example, the surface of the casing has a relatively fixed flange mounting surface, so the design clamp When tightening the device, the flange mounting surface can be used to quickly and accurately clamp the gearbox housing. [0003] However, the new energy vehicle gearbox is driven by a motor, with a high speed of about 10,000r / min, and a large amount of vibration. At the same time, the structure of the motor gearbox box is complex, and the clamping surface is small. The flange mounting surface is removed, and ...
