Description

A synchronizer automatic production line gear hub detection device

technical field

The invention relates to a synchronizer production line, in particular to a gear hub detection mechanism 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.

The invention not only has a simple and compact structure and takes up little space, but also requires no manual intervention in the whole detection process, has a high degree of automation, and has accurate and reliable detection results. The joint fixed on the piston rod of the cylinder is engaged with the "T" groove on the top of the slide plate. On the one hand, it is easy to disassemble and assemble, and the disassembly operation is convenient; Good synchronization of up and down movements. The rear end of the pad to be fed is clamped with the slide plate, and the pad to be fed is supported by the "L" shaped support on the slide, so that the pad to be fed is installed firmly without shaking from side to side.

The positioning plate (6) is a rectangular plate structure, and the four corners of the positioning plate (6) are fixed to the top plate (2) through small columns (9). In the above structure, not only the positioning plate is firmly connected under the top plate, but also the space surrounded by the four small columns provides a location for the displacement sensor, which can make the structure more compact.

In order to facilitate assembly and further enhance the reliability of the connection between the positioning plate and the top plate, the small column (9) is a three-section cylindrical structure with small ends at the upper and lower ends and a large middle in the middle, and the upper end of the small column (9) extends into the top plate (2 ), and tightly fit with the top plate (2); the lower end of the column (9) stretches into the positioning plate (6), and tightly fits with the positioning plate (6).

Beneficial effects: the invention is reasonable in design, simple and compact in structure, small in size, occupies little space on the production line, and is conducive to layout; the cylinder drives the backing plate to move upwards, and can detect the gear hub workpiece in combination with the gear hub detection mould. Whether the pose meets the requirements, not only the detection speed is fast, the degree of automation is high, but the detection result is accurate and reliable; by replacing the gear hub detection mold, it can adapt to the detection of gear hubs of various specifications, and has good versatility.
