Embodiment Construction

[0027] Specific embodiments of the present invention will be described below with reference to the drawings.

[0028] Such as figure 1 , the base 3 of the shifter assembly performance test test machine is installed on the workbench 1, and the base 3 is used to fix the shifter seat 51 of the shifter assembly, wherein the shifter assembly also includes a shift lever 53. The positioning connection method of the shifter base 51 is to set a number of positioning pins on the machine base 3, and set a number of positioning holes matching the number, position and shape on the shifter base 51, and connect the positioning pins and positioning holes together. After a corresponding assembly, the shifter base 51 can be positioned on the machine base 3 . The base 3 is also provided with several pneumatic clamping parts 41. After the shifter seat 51 is positioned, the pneumatic switch can be turned on to drive the pneumatic clamping parts 41 to fix the shifter base 51 on the base 3 on.

Abstract

The invention provides a testing machine for testing the performance of a reverse gear assembly, comprising a stander for installing a reverse gear seat, a bracket making movement relative to the stander, a first rotating coder for detecting the rotating amplitude of a bottom frame, a second servo motor which is connected with a vertical frame through a screw rod and drives the vertical frame to make pivoting around the second pivoting axis corresponding to the bottom frame, a second rotating coder for detecting the rotating amplitude of the vertical frame and a force sensor for detecting the value of the gear shifting force of the reverse gear assembly, wherein the bracket comprises the bottom frame pivoting around a first pivoting axis, the vertical frame pivoting around the second pivoting axis and a pawl which is arranged on the vertical frame and used for clamping a reserve gear rod, and further comprises a first servo motor which drives the bottom frame to make pivoting around the first pivoting axis relative to the stander;. The testing machine for testing the performance of the reverse gear assembly has the advantages of higher automatization degree, accurate gear shifting force measurement and accurate and controllable rotating amplitude due to the rotation of the vertical frame driven by the screw mandrel, which is beneficial to test.

Description

technical field [0001] The invention relates to an assembly performance testing machine for an automobile shifter. Background technique [0002] The car shifter assembly is an important part of the car. Before it is installed on the car, the performance test of the gear shifting, gear selection and reverse gear assembly should be carried out under the specified environmental conditions according to the actual loading and running state. Tests, as well as a series of tests such as shift force and electrical signal tests, provide more comprehensive test data to determine whether the performance of the automotive shifter assembly meets the design and product quality requirements. In order to facilitate testing, reduce test costs and comprehensive To judge the quality of the product, the above tests need to be carried out on a comprehensive test testing machine. [0003] At present, manufacturers often use manual inspection when testing the performance of shifters. Due to the di...
