Servo-controlled combined flexible positioning device for car roof

Abstract

The invention relates to a clamping positioning device in the technical field of mechanical engineering and in particular relates to a servo-controlled flexible positioning device for a car roof. The servo-controlled flexible positioning device is composed of a base, a positioning-block flexible mechanism, a positioning-pin flexible mechanism and a control system; according to a detection object, the positioning-block flexible mechanism and the positioning-pin flexible mechanism are selected to be mounted on the base and connected with the control system, respectively. The control system is composed of an adjustment amount calculation module and a positioning adjustment control module, and is connected with each of stepping motors of horizontal movement components and vertical movement components of the positioning-block flexible mechanism and the positioning-pin flexible mechanism, and a cylinder electric valve of a positioning block clamping component in the positioning-pin flexible mechanism. The flexible positioning device takes the place of a traditional special detection tool, and is convenient to utilize, reasonable in structure, high in positioning accuracy in detection, high in universality and low in detection cost.

Description

1. Technical field [0001] The invention relates to a clamping and positioning device in the technical field of mechanical engineering, in particular to a servo-controlled flexible positioning device for a top cover of a car. 2. Background technology [0002] The manufacturing process of automobile body sheet products is complicated and there are many influencing factors. The quality directly affects the performance of appearance, wind noise and driving safety. This requires the use of a large number of inspection tools for quality inspection in the stamping and welding process of body sheet products . The special inspection tool is still the main tool for the inspection of the current body thin plate products, but due to the short development cycle and fast replacement of modern automobile body products, this results in a large amount of inspection tools and a very high cost, so the development of applicable tools has high precision and versatility. It is very urgent to rep...

Problems solved by technology

However, this invention only provides a mechanism design for the positioning adjustment of a single fixture positioning pin, and lacks an overall flexible positioning device system design for similar parts of the automobile body product family

[0004] The reconfigurable positioning system is the development trend of the design of inspection tools or fixtures for automobile body products. However, according to the structure and positioning characteristics of automobile body product families, a flexible positioning device system is used to realize the rapid positioning and switching of similar structural parts of different models. Clamping, testing or welding, the current design of flexible positioning devices cannot meet this demand
