Embodiment Construction

[0029] Figure 1 to Figure 5 As shown, the common internal grinder tooling fixture used for processing the nozzle hole drilling template of the present invention includes a fixture seat 1 and a positioning pin 2, wherein the fixture seat 1 is a disc-shaped structure, and the center of the fixture seat 1 is provided with a hole for matching the grinding machine. Process the step hole 11 of the drill template 4, and the fixture seat is provided with corresponding positioning pin holes 13 and pressing screw holes 12 according to the hole distances of the drill template 4, which are used to position or fix the drill template 4, and the drill template 4 passes through the positioning pins 2 is positioned so as to be fixed on the end face of the fixture seat 1 for processing. Each positioning hole on the drilling template 4 is processed through 4 times of clamping respectively, wherein the accuracy of the positioning pin hole 13 on the fixture seat is about 1 / 3 higher than that of e...

Abstract

The invention discloses a tool fixture and a method for processing a bush plate by a common internal grinding machine. The tool fixture comprises a fixture base and stop pins, wherein the center position of the fixture base is provided with a step hole matched with the grinding machine to drill and grind the bush plate; the fixture base is provided with corresponding stop pin holes and pressing screw holes according to each hole distance of the bush plate; and the bush plate is positioned by the stop pins so as to be fixed on the end surface of the fixture base. The method for processing the bush plate by the tool fixture comprises the following steps: the fixture base is clamped on the main shaft of the grinding machine by a four-jaw chuck; the end surface of the fixture base is positioned; the bush plate is tightened by screwing the bolts in the pressing screw holes; the bush plate is fixed on the end surface of the fixture base to be processed after being positioned by the stop pins; and each locating hole on the bush plate is processed and finished by four-time clamping. The tool fixture has the advantages of high processing precision, high working efficiency and low equipment and grinding tool.

Description

technical field [0001] The invention relates to a fixture, in particular to a tooling fixture and a method for processing a drill formwork with an ordinary internal grinder. Background technique [0002] Drilling template is a drilling template for processing spray hook holes and positioning holes of the machine body. The mutual position of each positioning hole on the drilling template is required to reach ±0.01mm. For a long time, the four holes have been ground on a trajectory coordinate grinding machine. The four holes can only be grinded on a special processing machine tool - track coordinate grinding machine. This special machine tool is a high-precision digital display device. The digital display accuracy can ensure the positional tolerance between the pin holes of the part. The verticality accuracy between the working platform and the working platform is very high, which can ensure the straightness of each pin hole and other shape tolerances, and can ensure that the ...
