Problems solved by technology

However, the worktable of the dynamometer and the four corners of the lifting plate are positioned through the positioning rod and the positioning sleeve, and there is no part for locking the workbench and the lifting plate. During work, the workbench and the lifting plate are easily Shaking may easily lead to low test accuracy of the car chassis

Embodiment 2

[0033] Such as Figure 1-2 Shown, a kind of locking method that is used for automobile chassis measurement comprises the steps: set a rectangular frame 2 on four positioning rods 1 on the upper end surface of the workbench 5, and set a rectangular frame 2 on the four right angle points of the rectangular frame 2 Tubular follower blocks 7 are respectively provided on the top, and one follower block 7 is respectively sleeved on a positioning rod 1, and cylinders 3 are respectively provided on the bottoms of the two sides parallel to each other on the rectangular frame 2, and the cylinders 3 are used as power output parts. Provide power for the lifting of the rectangular frame 2, that is, when the lifting plate 11 rises or falls, the rectangular frame 2 is always in sync with the lifting plate 11, because the middle part of the bottom surface of the lifting plate 11 is supported by the screw 4, so the lifting plate 11 occurs Shaking is usually at its four right angles, and when t...

Abstract

The invention discloses a locking device and a locking method which are used for automotive chassis power testing. The locking device comprises a rectangular frame; servo blocks are fixedly arranged at four right angle points of the rectangular frame correspondingly; locating rods are sleeved with the servo blocks; a plurality of grooves are formed in the inner peripheral wall of each servo blockin the circumferential direction of the corresponding servo block; electromagnets I are slidingly arranged in the grooves; the outer side walls of the electromagnets I are connected with the groove bottoms of the grooves through springs; pressure sensors are arranged on the upper end faces of the servo blocks, and communicate with mains switches of the electromagnets I through controllers; and theoutput ends of two air cylinders are connected with the bottoms of two mutually parallel edges of the rectangular frame. The electromagnets I generate magnetic force after being electrified, the inner walls of the electromagnets I are attracted to the outer walls of the locating rods accordingly, the rectangular frame is locked to the locating rods, the upper surface of the rectangular frame is in contact with the bottom surface of a lifting plate, and the rectangular frame can provide stable support to the lifting plate, so that the four right angles of the lifting plate are prevented from shaking, and the precision of testing data is further ensured.

Description

technical field [0001] The invention relates to a dynamometer, in particular to a locking device and method for dynamometer of an automobile chassis. Background technique [0002] The dynamometer can test the entire performance curve of the motor from no-load to stalled. While testing the performance of the motor at no-load and load point, it can detect the input voltage, current, power, power factor, output torque, speed, output power, and efficiency; it is equipped with serial RS232 and printing interface; it can be divided into manual / Automatic test, automatic test time setting; can automatically draw the motor characteristic curve; with speed feedback control, torque compensation control and constant torque, constant speed function, can measure the characteristics of the unstable area of ​​the motor. And on the existing dynamometer, such as the lifting device (application number: 201320467853.7) of a kind of dynamometer disclosed in Chinese patent literature, comprise...
