Description

Technical Field

[0001] The utility model belongs to the technical field related to the processing of flange forks, and specifically relates to a fixture for flange fork holes. Background Art

[0002] The drive shaft flange fork is a mechanical component for connecting and transmitting power, and is commonly used in equipment such as automobiles, construction machinery, and ships. It mainly consists of parts such as a shaft sleeve, a flange, and a fork arm, etc., and is used for the connection between the driving shaft and the driven shaft. The intermediate shaft is connected in the connection hole between the flanges. When processing the connection hole of the flange fork, it is positioned and fixed through the blank shape of the flange fork, and fixed by clamping with a four-jaw chuck. Due to the large error in the blank size, during the actual processing process, it is necessary to use a dial indicator to align. Taking the inner hole of the flange blank as the reference for alignment, and comparing the outer diameter of the flange as the adjustment reference, to perform hole turning processing. The process of using a dial indicator to align takes a long time, and it is necessary to repeatedly adjust the jaws for borrowing, resulting in a long auxiliary time for flange fork hole processing and low processing efficiency.

An adjustment and cooperation chute 10 is provided on the fixed chuck 1. A clamping jaw one 2 and a clamping jaw two 14 are arranged and installed in the adjustment and cooperation chute 10. A clamping arc plate one 3 is fixedly arranged at the clamping position of the clamping jaw one, and a clamping arc plate two 15 is fixedly arranged at the clamping position of the clamping jaw two 14. Positioning support seats one 4 and two 5 are symmetrically arranged on both sides of the flange fork body 8. Positioning holes are correspondingly provided on both the positioning support seat one 4 and the positioning support seat two 5. A positioning pin shaft 13 is arranged and installed through the positioning holes. A pin shaft end plate 11 is arranged at the end position of the positioning pin shaft 13, and a fixing screw 12 is installed on the outer side of the pin shaft end plate 11.

[0024] Among them, the fixed chuck 1 selects a two-jaw chuck. The clamping arc plate one 3 and the clamping arc plate two 15 are symmetrical about the midline of the fixed chuck 1. The clamping arc plate one 3 and the clamping arc plate two 15 are used to clamp and fix the two sides of the flange fork arm of the flange fork body 8.

[0025] The connection line between the positioning support seat one 4 and the positioning support seat two 5 forms a cross structure with the adjustment and cooperation chute 10.
