Description

A detection mechanism for gear hub groove width and ring groove major diameter

technical field

The invention relates to a synchronizer production line, in particular to a gear hub groove width and ring groove large diameter 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.

Rotating cylinder (4) is installed at the bottom of positioning plate (3), and the piston rod of described rotating cylinder (4) is vertically downward, and is connected with the upper end of rotating mold (5), installs at the bottom of rotating mold (5) Detecting mold (6); under said detecting mold (6) is provided with the backing plate (7) to be prepared, and the center of the bottom of the backing plate (7) is supported by the piston rod of the second cylinder (8), and the second cylinder (8) and the first cylinder (2) are located on the same vertical line.

With the above technical scheme, the gear hub workpiece to be inspected is transferred to the pad for material on the production line, and is located directly below the detection mold. The plate and the gear hub workpiece move upward quickly until the gear hub workpiece is close to the detection mold; the piston rod of the first cylinder extends downward, so that the positioning plate, the rotary cylinder, the rotary mold and the detection mold move downward until the detection mold is inserted into the gear. In the hub workpiece, start the rotary cylinder again, so that the rotary mold and the detection mold rotate relative to the gear hub workpiece. If the width of the gear hub groove and the major diameter of the ring groove meet the requirements, the above operations can be carried out smoothly; otherwise, it can be judged that the detected gear hub workpiece does not meet the requirements.

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 four first guide pillars move up and down together with the positioning plate to play a guiding role, so as to ensure that the positioning plate and the detection die only move in the vertical plane. The first guide sleeve plays the role of wear resistance, so as to prevent the first guide post from being worn and ensure smooth movement of the first guide post. The first guide sleeve is simple in shape, easy to install on the top plate of the rack, and firmly connected.

Preferably, the positioning plate (3) is a rectangular plate structure.

The piston rods of the cylinder (8) are parallel, the upper end of the second guide post (12) is fixed with the bottom of the mounting plate (11), and the lower end of the second guide post (12) is embedded from the mounting plate (11). The two guide sleeves (13) pass through, and the second guide post (12) is slidingly fitted with the second guide sleeve (13). The second guide column of the above structure moves up and down together with the backing plate to be fed, and acts as a guide, so as to ensure that the backing board to be fed and the gear hub workpiece only move in the vertical plane. The second guide sleeve plays the role of wear resistance, so as to prevent the second guide post from wearing out and ensure the smooth movement of the second guide post.

The top of the second guide sleeve (13) is integrally formed with a head disc, which is supported by the top surface of the mounting plate (11), and the head disc is fixed to the mounting plate (11) by screws. The bottom end of the second guide sleeve (13) exceeds the bottom surface of the mounting plate (11). The second guide sleeve of the above structure is simple in shape, easy to install on the mounting plate, and firmly connected.

Beneficial effects: the present invention is simple and compact in structure, small in size, occupies little space on the production line, and is favorable for arrangement on the production line; it is driven by two air cylinders and a rotating air cylinder, and combined with a detection mold, the groove width and ring of the gear hub can be detected. Whether the large diameter of the groove meets the requirements, not only the detection speed is fast, but also the detection process is stable, and the detection result is accurate and reliable.
