Abstract
The utility model relates to a fixture for machining shaft parts, and in particular relates to a plane grinding fixture for eccentric shaft necks of shaft parts. The plane grinding fixture comprises a base, a positioning shaft sleeve, a pressing block and an axial circumferential positioning block, wherein the axial circumferential positioning block is provided with an axial stop dog and is connected with a positioning bolt in a rotating manner. With the adoption of the fixture provided by the utility model, angle and depth sizes of grinding and machining eccentric planes of the eccentric shaft necks of the shaft parts are not influenced by shape and position precision of the eccentric shaft necks.
Description
Technical field
The utility model relates to the anchor clamps that Machining of Shaft-type Parts is used, particularly the flat surface grinding anchor clamps of axial workpiece rotor journal.
Background technology
There are one type of axial workpiece such as compressor crank shaft to have rotor journal; On rotor journal, be processed with an off center plan 10; Like Fig. 4, shown in Figure 5, have the rotor journal end at axial workpiece and also be processed with a plane 11,10 one-tenth of off center plans on this plane 11 and the rotor journal are near 90 ° angle.Off center plan on the rotor journal needs to carry out the clamping location with the anchor clamps of special use in Grinding Process.Existing clamping positioning fixture is made up of base, location axle sleeve, briquetting and axially circumferential locating piece; The location axle sleeve is fixed on has two groups of location axle sleeves at least on the base; Each group location axle sleeve is made up of two location axle sleeves arranging vertically, locate axle sleeve can with the axial workpiece matched in clearance.Briquetting is installed on the base through the bolt that vertically is rotatably connected on the base, and after axial workpiece was arranged in the location axle sleeve, the briquetting two ends were pressed abd fixed on locating shaft with two axial workpieces simultaneously and put under the bolt effect.Axially circumferentially locating piece is positioned on the locating shaft cover axis direction; Be used for the axial and circumferential of axial workpiece are positioned; It is made up of axial location seat and eccentric locating piece; The axial location seat is realized the axial location of axial workpiece through the conflict to the step end face (being the step end face that forms between axial workpiece main shaft and the rotor journal) of axial workpiece, and eccentric locating piece then is the circumferential location of realizing axial workpiece through the external cylindrical surface of rotor journal.
Because the axial workpiece that has rotor journal is in process; The eccentric throw of rotor journal has mismachining tolerance; And axial workpiece quench, rotor journal will produce distortion in the trimming process; So realize off center plan that the circumferential location of axial workpiece will cause rotor journal after grinding through the external cylindrical surface of rotor journal, its angle and depth dimensions do not reach designing requirement, thereby cause scrapping of axial workpiece.
Summary of the invention
The purpose of the utility model provides a kind of flat surface grinding anchor clamps of axial workpiece rotor journal, makes angle and the influence that depth dimensions does not receive rotor journal shape and positional precision of grinding of the off center plan of axial workpiece rotor journal.
The flat surface grinding anchor clamps of the said axial workpiece rotor journal of the utility model; Comprise base, be fixed on location axle sleeve on the base, be installed in the briquetting on the base; And be fixed on the base and be positioned at the axially circumferential locating piece on the locating shaft cover axis direction, axially circumferentially locating piece is provided with axial stop, and axial stop and location axle sleeve are along the locating shaft cover axially relatively; And when axial workpiece was arranged in the location axle sleeve, the step end face of axial workpiece can be conflicted with axial stop; Axially circumferentially be connected with bolt on the locating piece, bolt is axially vertical with the locating shaft cover, and when axial workpiece was arranged in the location axle sleeve, the bolt front end can be conflicted with the plane that axial workpiece has on rotor journal one end.
During detection, axial workpiece is interspersed in the axle sleeve of location, and the time axial workpiece have plane on rotor journal one end towards bolt.Axial workpiece is advanced to axially circumferential locating piece direction; Make the step end face and the axial stop of axial workpiece inconsistent; Rotate axial workpiece then, make axial workpiece have plane and bolt front end on rotor journal one end inconsistent after, with briquetting axial workpiece is pressed abd fixed on locating shaft and puts; Promptly accomplish the clamping of axial workpiece, can realize the grinding of the off center plan of axial workpiece rotor journal.
Through changing the thickness of the axial stop on the axial circumferentially locating piece, can regulate the length dimension of the off center plan that grinding goes out; Through the positioning of rotating bolt, regulate the bolt front end and protrude in axially circumferentially locating piece surface height, the i.e. angle of scalable off center plan and depth dimensions.
The utility model is owing to adopt axial workpiece to have the circumferential location that axial workpiece is realized on the plane on rotor journal one end; So make angle and the influence that depth dimensions can not receive rotor journal shape and positional precision of grinding of the off center plan of axial workpiece rotor journal; The angle of off center plan and depth dimensions precision then can realize that operation is very easy in adjusting through regulating bolt.

The specific embodiment
Extremely shown in Figure 3 like Fig. 1; The flat surface grinding anchor clamps of this axial workpiece rotor journal comprise base 1, location axle sleeve 2, briquetting 4 and axially circumferential locating piece 9; Location axle sleeve 2 has two groups, and it is fixed on the base 1, and each group location axle sleeve 2 is made up of two location axle sleeves 2 arranging vertically; The location is equipped with and locatees the lining 3 of axle sleeve 2 interference fit in the axle sleeve 2, location axle sleeve 2 through lining 3 can with the axial workpiece matched in clearance.Briquetting 4 is installed on the base 1 through the bolt 5 that vertically is rotatably connected on the base 1; Be set with compression spring 6 on the bolt 5; After axial workpiece was arranged in location axle sleeve 2, briquetting 4 two ends can be pressed abd fixed on two axial workpieces on the axle sleeve 2 of location under bolt 5 effects simultaneously.Axially circumferentially locating piece 9 is fixed on the base 1 and is positioned on axle sleeve 2 axis directions of location; Axially circumferentially locating piece 9 is provided with axial stop 8; Axial stop 8 is fixed by bolts on the axially circumferential locating piece 9; Axle sleeve 2 is axially relative along the location for axial stop 8 and location axle sleeve 2, and when axial workpiece was arranged in location axle sleeve 2, the step end face of axial workpiece can be conflicted with axial stop 8.Axially circumferentially be connected with bolt 7 on the locating piece 9, bolt 7 is axially vertical with location axle sleeve 2, and when axial workpiece was arranged in location axle sleeve 2, bolt 7 front ends can be conflicted with the plane 11 that axial workpiece has on rotor journal one end.
