Machining device for casting gear blank part

Abstract

The invention discloses a processing device for casting a gear blank. The processing device includes a fixing mechanism and a cutting mechanism used in conjunction. The fixing mechanism includes a workbench, a fixed shaft is arranged on the workbench, and an abutment part is arranged on the fixed shaft, and the abutment part can be fixed The abutment part includes an inner ring and an outer ring connected by a spring, the inner ring is made of elastic material, and the fixed shaft includes a first fixed shaft and a second fixed shaft with different inner diameters. The processing device of the present invention is simple in structure and simple in operation, and the abutting portion can adapt to gears of different sizes through the inner ring and the outer ring, thereby satisfying different processing requirements.

Description

technical field [0001] The invention relates to a processing device for cast gear blanks, belonging to the technical field of mechanical processing. Background technique [0002] Gears are wheel-shaped mechanical parts that transmit torque by the meshing of teeth. The gear can achieve functions such as changing the speed and torque, changing the direction of motion, and changing the form of motion through transmission with other toothed mechanical parts (such as another gear, rack, and worm). Due to the advantages of high transmission efficiency, accurate transmission ratio, and large power range, gear mechanisms are widely used in industrial products, and their design and manufacturing levels directly affect the quality of industrial products. The teeth of the gear interlocking with each other will drive the other gear to rotate to transmit power.

Problems solved by technology

[0003] When manufacturing gears, the traditional blank cutting is to place the blank horizontally on the cutting table. When cutting, the chipping at the cutting place will be scattered on the workbench. When the tool is cutting, it is affected by the chipping, which is not only easy to damage The cutting tool will also make the cutting surface uneven and fail to meet the expected cutting requirements; the cutting length is fixed, and the cutting length cannot be changed according to actual needs

It has been improved. The cutting piece is placed in the vertical fixing mechanism for cutting, and then a channel is set to discharge the chipping, which solves the problem that the cutting chipping affects the cutting quality, but there are still deficiencies. The length is fixed, which cannot meet the cutting requirements of different types of gear blanks
