Embodiment

[0028] It can be seen from the accompanying drawings in the specification;

[0029] In a free state: the spring 6 supports the sliding cylinder 7 against the second cage and the four first steel balls 10 , and is in contact with the cover 4 .

[0030] During the downward insertion process of the guide post 2, the inclined plane of the groove 14 of the guide post 2 squeezes the four first steel balls 10 on the second cage, so that the second cage and the first steel balls 10 apply force downward on the slider. 7, the sliding cylinder 76 overcomes the force of the spring 6 and moves down to the bottom point; the four second steel balls 8 on the first ball cage 5 change positions so that the guide posts 2 can all enter the zero positioner smoothly.

[0031] There are eight first steel balls 10 and second steel balls 8 in total, and the slope of the groove 14 in the guide post 2 is a 45° conical surface.

[0032] After the guide post 2 enters, automatic locking is realized, the f...

Abstract

The invention discloses a zero-point positioner structure for a production assembly line, and relates to the technical field of production equipment, the zero-point positioner structure comprises a base and a guide pillar, the base is fixedly provided with a shell, the upper end of the shell is fixedly provided with a sealing cover, and the upper wall surface of the sealing cover is provided with an insertion hole. A parallel and relative pressing locking mode is adopted, the sections of conical surfaces on the two pressed sides of a steel ball are in a parallel state, the clamping state is stable and firm, acting force in other directions cannot be generated on the steel ball even if the tension of a guide column is increased, the locking force is greatly improved, radial positioning and axial positioning are very firm, and unless an air cylinder is used for opening a sliding barrel, as long as equipment is intact, the sliding barrel can be locked. The locking mechanism can completely lock the special positioning guide column, the zero-point positioning device is suitable for zero-point positioning of a reverse tool, when the positioning guide column is taken out, the guide column can be taken out only by connecting air pressure to the bottom air cylinder, cleaning is convenient, the zero-point positioning device is of a mechanical structure, and the bottom air cylinder is detachable and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of production equipment, in particular to a zero point locator structure for a production assembly line. Background technique [0002] In a large-scale production assembly line, workpieces and tooling often need to move between stations. After each station change, the first thing to do is to align the coordinate system of the workpiece and determine the zero point of the workpiece, and then the workpiece can be precisely processed, which is time-consuming and laborious. . [0003] The zero point locator is used to realize that when the processing tooling is changed from one station to another, the zero point of the processing tooling is the same zero point, which can save the time of manually looking for the zero point and improve production efficiency. [0004] The traditional zero-point positioning device adopts single-layer ball pressing and positioning, which has small positioning clamping force, small ...
