Description

A device for detecting large diameter of splines in gear hub of automatic production line of synchronizer

technical field

The invention relates to a synchronizer production line, in particular to a large-diameter detection mechanism for splines in gear hubs on the synchronizer assembly detection line.

Background technique

At present, before the gear hub and gear sleeve of the synchronizer are assembled together, a series of inspections such as the major diameter of the spline inside the gear hub, the width of the hub groove, the major diameter of the ring groove, the position of the shift fork groove of the gear sleeve, etc. are required. Inspection, all inspection operations and assembly operations after inspection are carried out manually, so each shift needs 20 people, not only the labor cost is high, the efficiency of inspection and assembly is low, but also the accuracy of inspection and assembly is difficult to guarantee, and the consistency cannot be satisfied. requirements for sexual production.

If a fully automatic production line is designed, the detection and assembly of gear hubs and gear sleeves are all carried out automatically on the production line, which will greatly improve the production efficiency of the synchronizer and ensure product quality. But how to build a synchronizer automatic production line that meets the functional requirements is a technical problem that is urgently to be solved in the industry.

Sensors, rotary molds and other components are arranged, and there will be no shaking when the servo electric cylinder and rotary cylinder are in operation.

Between the positioning plate (2) and the top plate (3), there are four uprights (11) distributed in a rectangle and parallel to each other, the uprights (11) are perpendicular to the top plate (3), and the top plate (3) passes through these four Column (11) is supported on the positioning plate (2). The top plate of the above structure is installed with good stability, and the space surrounded by the four columns can be used to arrange the rotary cylinder, making the structure more compact.

In order to simplify the structure, facilitate assembly, and ensure the solidity of the connection between the top plate and the positioning plate, the column (11) is a cylinder, and the upper and lower ends of the column (11) are uniformly formed with a small-diameter end, and the upper end of the column (11) is The small-diameter end of the column (11) protrudes into the top plate (3) and is tightly fitted and fixed with the top plate (3); the small-diameter end of the lower end of the column (11) extends into the positioning plate (2) and is tightly fitted and fixed with the positioning plate (2) .
