Embodiment Construction

[0069] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.

[0070] In order to ensure the safety of the operator, ensure the accuracy of the test results and improve the test efficiency, the present invention provides a cam linkage mechanism. When using this mechanism to disassemble and assemble the wiper spring, it is only necessary to rotate the handle 180 degrees to complete the wiper. The disassembly and assembly of the spring is easy to use, and the wiper spring can be disassembled and assembled safely under the condition that the wiper is not damaged.

[0071] The structure of the cam linkage mechanism is as figure 2 and image 3 As shown, the cam linkage mechanis...

Abstract

The invention relates to the technical field of automotive test, in particular to a cam-link mechanism to demount and mount wiper springs. The cam-link mechanism disclosed herein comprises: a dual-rocker mechanism, comprising a driving rocker, a driven rocker, a link and a frame, wherein one end of the driving rocker and one end of the driven rocker are connected with the frame, the other ends ofthe driving rocker and driven rocker are connected with the link, and the other end of the link is connected with a C-shaped hook of a wiping rod assembly; a cam mechanism composed of a cam and a handle, wherein the handle is connected with the cam, and the cam is in contact with the driving rocker, the handle is rocked to rotate the cam to drive the driving rocker to rock, the driving rocker drives the driven rocker and the link to move, and the link moves back and forth to drive the C-shaped hook so as to complete spring demounting and mounting. The cam-link mechanism has the advantages thatwiper springs can be demounted and mounted in nondestructive manner, test precision is guaranteed, safety and reliability are good, the problem is solved that an original demounting-mounting mode ishigh in time and labor consumption, easily causes damage to parts and has certain danger, and the innovation and development range is wider in the field of wiper test.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a cam linkage mechanism for disassembling and assembling a wiper spring. Background technique [0002] The car wiper is an important safety part of the car, and it is a cleaning tool for cleaning rainwater and other pollutants on the car glass. The function test is an important test of auto parts, and the wiper spring often needs to be disassembled in the wiper function test. [0003] Figure 1a It is a typical structural diagram of the wiper rod assembly. The wiper rod assembly is composed of a wiper rod 11, a wiper spring 12, a C-shaped hook 13 and a wiper arm 14. One end of the C-shaped hook 13 is connected to the wiper spring 12, and the other end is connected to the For the wiper arm pin 142 , the C-shaped hook 13 needs to be removed from the wiper arm pin 142 when the wiper spring 12 is removed, and the C-shaped hook 13 needs to be connected to the wiper arm pin...
