Problems solved by technology

[0003] Slotting machine processing is to use the vertical reciprocating linear motion of the slotting knife to slot the keyway. Its processing productivity and precision are low, and it is mostly used in single-piece or small batch production. The service life of the slotting knife is low and the manufacturing cost is high. In mass production, it is usually Replaced by milling machines and broaching machines
[0004] Broaching is usually aimed at the processing of inner holes or keyways, with strict requirements for processing positioning, difficult control of processing quality, low broach life and high manufacturing costs
[0005] Wire cutting processing has disadvantages such as low processing efficiency, high processing cost, and poor surface quality of parts.

Abstract

The invention discloses a device used for machining part inner hole convex and concave keys. The device comprises a connecting device, a power device and a positioning device. The power device is connected to the connecting device. The connecting device is installed on a lifting frame of a horizontal milling machine. The power device is used for transmitting power of a main shaft of the horizontalmilling machine to a milling cutter on the power device to conduct milling machining through gear transmission. The positioning device is connected with an indexing plate of the horizontal milling machine for use and is used for positioning different sizes of parts. According to the technical scheme of the device, the common horizontal milling machine is used for machining part inner hole convexkeys or grooves, due to rotary milling machining, the machining efficiency is high, the cost of the cutter is low, and the service life of the cutter is long.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a device for processing convex and concave keys in inner holes of parts. Background technique [0002] In the machining process, the machining of the convex key or groove in the inner hole of the part (such as figure 1 , is a schematic diagram of an inner convex key part), the figure is a blanking workpiece, the width of the keyway has a machining allowance, and the keyway of the part is usually finished by slotting machine, broaching machine, wire cutting and other processing methods. [0003] Slotting machine processing is to use the vertical reciprocating linear motion of the slotting knife to slot the keyway. Its machining productivity and precision are low, and it is mostly used in single-piece or small batch production. The service life of the slotting knife is low and the manufacturing cost is high. In mass production, it is usually Replaced by milling machi...
