Problems solved by technology

Although the flexible positioning device can adapt to the positioning and clamping of roof covers of different sizes in different models, the adjustment of the flexible positioning in this device can only realize the servo adjustment in two directions, while the third direction needs manual adjustment, which is difficult to realize three directions. High-precision and fast servo adjustment of the direction, so it is difficult to apply the positioning and clamping of a wider range of different structures and different sizes of top covers

Abstract

The invention relates to a car top cover flexible clamp system and a using method thereof, belonging to the technical field of clamping and positioning devices. The system includes a base, a guide rail motor, a lead screw A, a flexible positioning surface device and a flexible positioning pin device, wherein circular guide rails are evenly and symmetrically arranged on the base, a guide rail motor is arranged inside the circular guide rail, and a flexible guide rail motor is provided on the guide rail motor. Positioning surface device, two long guide rails are arranged side by side on one side of the base, and two lead screws A are arranged between the two long guide rails. Both ends of the lead screw A are connected to the base through bearings, and one end of the lead screw A is connected to a lead screw. The motor A and the lead screw A are provided with a flexible positioning pin device. The invention realizes the positioning and clamping of car top covers of different structures and sizes through three-degree-of-freedom adjustment, can be used for top cover welding and testing, replaces traditional special fixtures, and reduces the cost of new product development.

Description

technical field [0001] The invention relates to a car top cover flexible clamp system and a using method thereof, belonging to the technical field of clamping and positioning devices. Background technique [0002] The car body is welded by many stamping parts through multiple welding stations. Each welding station has a set of special fixture system to ensure the relative positioning and welding clamping of welding parts. Fixture development Cost is a very important part of the new model development process. In order to reduce the cost of fixture development, it is necessary to replace the traditional special fixture system with a flexible fixture system. [0003] Chinese patent document CN105171642B discloses a servo-controlled car roof assembly flexible positioning device. The flexible positioning device is composed of a base, a positioning block flexible mechanism, a positioning pin flexible mechanism, and a control system; the positioning block flexible mechanism and t...
