Problems solved by technology

The disadvantage is that it is necessary to consider errors caused by thermal deformation, force deformation, wear, and fit clearance, so real-time measurement devices, feedback devices, and compensation devices must be added (Wang Hongtao et al., "Ball screw pitch error compensation method improves the positioning of CNC machine tools. Research on Accuracy", Aeronautical Precision Manufacturing Technology, 2001, Volume 37, Issue 5), thus increasing the cost

Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] The structure of the present invention is as figure 1 , 2 shown. The two ends of accompanying platform 4 are placed on guide rail 1, and accompanying platform 4 can move on guide rail 1. The nut 3 is located in the middle of the bottom surface of the accompanying platform 4, and is fixedly connected with the accompanying platform 4. The screw mandrel 2 is placed in the middle of the two guide rails 1 and is parallel to the guide rails 1 . Both ends of the screw mandrel 2 are respectively positioned by a double-row radial thrust bearing 13 and a deep groove ball bearing 14 , and driven to rotate by a motor 12 . The screw mandrel 2 and the nut 3 form a helical motion pair, and when the screw mandrel 2 rotates, the nut 3 is driven so that the accompanying table 4 moves on the guide rail 1 . The special positioning cylindrical pin 9 is...

Abstract

A non-interference precise locating mechanism for multi-position machining system is disclosed. A following table can move along guide tracks. A leading screw matched with nut is parallelly arranged between two guide tracks. The locating pin on the following table is matched with the locating sleeve tubes on the bottom of bench, which is controlled by a cylinder for moving up and down relatively to the following table. The locating holes at both ends of bench are matched with the locating pins on locating table of working positions. Its advantages are high locating precision, small size, light weight and low cost.

Description

Technical field: [0001] The invention relates to a non-interference precision positioning mechanism for a multi-station processing system, which uses the change of the effective positioning section of multiple sets of positioning pins at different positions in the axial direction to realize the precise positioning and positioning of each station of the multi-station processing system. The non-interfering positioning mechanism among the stations belongs to the technical field of flexible manufacturing. Background technique: [0002] With the improvement of production capacity requirements, automatic production lines are more and more widely used in factories. The automatic production line not only requires the automatic transmission of products at different processing stations, but also requires them to be able to achieve fast and accurate positioning at each station. In the traditional production line, the positioning work is mainly done manually; with the improvement of au...
