Description

Guide block recessing fixture

Technical field

This utility model belongs to the fixture of processing selector gear parts, especially guide block recessing fixture。

Background technology

Guide block belongs to selector gear parts, and at present the groove on processing guide block adjutage is to adopt milling machine groove milling, once can only one workpiece of clamping, production efficiency is low, and labor intensity is big。

Summary of the invention

In order to improve the groove working (machining) efficiency on guide block, reduce labor intensity, the utility model proposes guide block recessing fixture, with car for milling, can the multiple workpiece of time processing。

For this, the technical solution of the utility model is: guide block recessing fixture, including ring flange body, it is characterised in that: ring flange body is uniformly distributed along the circumference and is provided with 3-12 guide block fixture unit, one guide block workpiece of each guide block fixture unit location clamping；

The structure of described guide block fixture unit: include positioning elastic mandrel device, postioning abutment, floating positioning pin device, the positioning elastic mandrel of positioning elastic mandrel device, postioning abutment are fixed on ring flange body, the centre bore of guide block workpiece is positioned by the positioning elastic mandrel of positioning elastic mandrel device, the supporting hold-down bolt that is provided with on positioning elastic mandrel, postioning abutment is spacing to guide block adjutage circumference；Floating positioning pin device and postioning abutment are correspondingly arranged, and floating positioning pin device includes spring, alignment pin, pilot bushing, and pilot bushing is fixed in the installing hole on ring flange body, and alignment pin leads in pilot bushing；Spring is arranged on alignment pin afterbody, and spacing by plug；The head of alignment pin is cone, it is achieved the circumferential floating clamping mechanism of guide block adjutage。

Beneficial effect: this utility model is by arranging multiple guide block fixture units at ring flange body, being arranged on lathe can the multiple workpiece of time processing, not only reach with the car purpose for milling, production efficiency is also greatly improved additionally, by the floating positioning pin device arranged on guide block fixture unit, ensure the reliable circumference floating clamping mechanism of guide block adjutage, it is achieved process safety is reliable。
