Space cam for slot machine transmission mechanism

Abstract

The invention provides a space cam for a slot machine transmission mechanism. An advancing spiral groove and a returning spiral groove are formed in the outer circumferential wall of a cam body and opposite in rotating direction and communicate with each other at the intersection of two ends. A stepped outer circumferential wall at one end of the cam body makes contact with a cam follower I arranged on a cutter bar shaft seat, and an arc-shaped protrusion is formed on a stepped outer circumferential wall at one end of the cam body. The advancing spiral groove and the returning spiral groove are matched with the cam follower fixed to a cutter bar shaft. A rotating shaft fixedly connected with the cam body drives the cam body to rotate so that the cam follower moves along the advancing spiral groove and the returning spiral groove to realize linear reciprocating motion of the cutter bar shaft afterwards. The space cam greatly simplifies a conversion structure of rotary motion and linearreciprocating motion; the arc-shaped protrusion acts on the cam follower I to finish the periodic swinging of cutter receding during slot processing; and the space cam is convenient and fast to install, small in occupied space and high in working reliability and use value.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a space cam used in a transmission mechanism of a slot machine. Background technique [0002] At present, when processing grooved parts, the main movement in the gear shaping machine or slot machine is usually realized by the crank linkage mechanism, and the crank linkage mechanism has the following defects in the use process: ① The structure is complex, when When the crank connecting rod mechanism breaks down, it is inconvenient to overhaul; ② Due to the complex structure of the crank connecting rod mechanism, it takes up a lot of space in the gear shaping machine or slotting machine, which is not conducive to the miniaturization design concept of equipment; As far as the processing of groove parts is concerned, the work reliability is poor. In view of the above problems, it is necessary to make improvements. Contents of the invention [0003] The te...
