Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
As shown in figs. 1-12, a kind of fixture for hole grinding, including ring flange 1 and the L shaped plate 2 on the ring flange,
Workpiece locating piece 5 is installed on the upper surface of the L shaped plate, for being positioned to workpiece 10 to be processed, the workpiece positioning
It is formed with block above the workpiece locating slot 51 that there is workpiece to import and export in outside, the workpiece locating piece and briquetting 8, institute is installed
State briquetting to be connected on hold-down bolt 3, the L shaped plate is threadedly coupled two spiral shells be arrangeding in parallel by the screwed hole 22 on the outside of it
Fixed after the lower end screw thread 62 of line pillar 6, the connection pressing plate 4 of threaded upper ends 61 of the thread pillar with nut, the compression spiral shell
Bolt is threadedly coupled with the pressing plate, in addition to one is used for by inserting in the radial direction through hole 101 of workpiece to be added, and will be to be processed
Part is imported and exported by the workpiece and positions the alignment pin 7 in the workpiece locating slot 51 of the workpiece locating piece.
Wherein, the workpiece locating slot 51 is as shown in fig. 6, be configured to the flute profile knot of the step-like axially symmetric structure of three-level
Structure, the top of the workpiece locating slot has centered about groove 52, the centralized positioning groove 52 and the end of the stepped stem 70 of alignment pin
Portion 71 is adapted, and the rod body part and the diameter of the radial direction through hole 101 of the workpiece of the connection end 71 of the alignment pin 70 are mutually fitted
Should, so by the use of alignment pin, after being inserted into the end 71 of alignment pin in centralized positioning groove 52, it is ensured that workpiece
