Description

Technical Field

[0001] The utility model relates to the technical field of pulley tooling, in particular to a copper-based powder metallurgy pulley tooling. Background Art

[0002] Pulleys are disc-hub parts. They are generally relatively large in size. The manufacturing process is generally based on casting and forging. Generally, larger designs are cast, and the material is generally cast iron (better casting performance), and cast steel is rarely used (steel has poor casting performance); generally, smaller ones can be designed for forging, and the material is steel. Pulleys are mainly used in situations where power is transmitted over long distances, such as the output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging machines, some small-horsepower motorcycle power transmission, agricultural machinery power transmission, air compressors, reducers, reducers, generators, cotton gins, etc.

[0003] There are various ways to process pulleys. Using copper as raw material for powder metallurgy is a common operation. After sintering, some testing and other processing may be required. At this time, various tooling is needed, such as clamps, cutting equipment, grinding equipment, etc., among which welding equipment is one of the indispensable tooling. The existing welding equipment is large-scale equipment and fully automated processing. This is for large batch orders. If the size of the output is small, manual installation is required. At this time, using large equipment will waste productivity. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a copper-based powder metallurgy pulley tooling, including a workbench, on which a first vertical plate and a second vertical plate are arranged in sequence, a first cylinder is arranged on the first vertical plate, and an upper positioning block is arranged at the output end of the first cylinder; a mounting plate is arranged on the second vertical plate, and a second cylinder is arranged on the mounting plate. A floating joint is arranged at the output end of the second cylinder, a fixed plate is arranged on the floating joint, and a welding gun is arranged on the fixed plate; a bearing seat is arranged on the workbench at a position corresponding to the upper positioning block, a rotating shaft is arranged in the bearing seat, a lower positioning column is arranged on the rotating shaft, and a rotating motor is arranged on one side of the rotating shaft.

[0006] Furthermore, a welding machine chassis is arranged at the bottom of the workbench, and ventilation and heat dissipation holes are arranged on the sides.

[0007] Furthermore, a first track is provided on the first vertical plate, and the upper positioning block is fixed on the first track via a first movable plate.

[0008] Furthermore, a second track is arranged on the second vertical plate, and the fixing plate is arranged on the second track.

[0009] Furthermore, a combined slide is provided at the bottom of the second vertical plate.

[0010] Furthermore, a protective cover is provided on the workbench.

[0011] The beneficial effects of the utility model are as follows: when in use, firstly, the processed pulley is placed on the lower positioning column at the bottom, and then the first cylinder on the first vertical plate is started to drive the upper positioning block to move downward to limit the top position of the workpiece. After the workpiece is limited and fixed, the second cylinder on the second vertical plate is used to drive the floating joint to move back and forth to adjust the position of the welding gun to realize spot welding operation. The structure is simple and easy to operate, and the simple fixing and rotation operations of the pulley can be realized. At the same time, the position of the welding gun can be adjusted according to different states to realize the function of simple welding operation. BRIEF DESCRIPTION OF THE DRAWINGS
