Processing jig of inclined hole of ball lock fixed seat

Abstract

The invention discloses a processing jig of an inclined hole of a ball lock fixed seat, comprising a base, an angle scale, a power output shaft, a DC motor and the ball lock fixed seat to be processed, wherein the base is locked on a roller wheel seat of a small internal grinding machine tool; the angle scale is arranged on the front part of the base and provided with an inclined surface; the power output shaft is arranged in the base and drives the angle scale to rotate; the DC motor is arranged on the tail part of the base and drives the power output shaft to rotate through first-stage speed change; the ball lock fixed seat to be processed is arranged on the inclined surface of the angle scale; one end of the power output shaft is connected with the bottom end surface of the angle scale, and the other end is connected with the DC motor.. The processing jig can ensure that the ball lock fixed seat to be processed is arranged on the inclined surface of the angle scale so that the small internal grinding machine tool can grind the inclined hole according to a method for grinding a normal straight hole; the processing jig is very convenient for disassembly and assembly without finding a position by a meter; if batch processing is carried out, the small internal grinding machine tool can process one inclined hole in 12 minutes, therefore the processing efficiency of one piece is enhanced by more than 10 times, and the cost is greatly reduced; and in addition, the processing jig is small and flexible, is convenient for clamping and has low processing unit price and high output.

Description

technical field [0001] The invention relates to a processing jig, in particular to a processing jig specially used for the oblique hole of a steam mold ball lock fixing seat. Background technique [0002] The existing method of grinding the oblique hole of the fixed seat of the steam model ball lock is a coordinate grinder (JG) processing method. Workbench, and lock it; then put the steam mold ball lock holder on the workbench, use a dial indicator to scan the position of the punch hole and the middle pin hole, so that the axes of the punch hole and the middle pin hole are perpendicular to the sine table Rotate the shaft, and fix the steam mold fixing seat magnetically. If the magnetic attraction is not strong enough, you can add a block around the steam mold fixing seat; then use the block gauge to pad the sine table to the required angle of 15 degrees, and plug it in the punch hole Insert the special plug gauge, find the position of the punch hole, reset the digital displ...

Problems solved by technology

[0003] The above-mentioned coordinate grinding machine processing method, the coordinate grinding machine consumes a lot of power, the grinding time is long, and the single-piece processing, and the auxiliary time such as table setting and clamping is long. It takes 120 minutes to process one piece, the single-piece cost is very high, and the output is low.
