Abstract
The utility model provides a fixture for grinding inner holes of a bush. The end surface of one side of a circular fixture body (2) is provided with an inner hole phi 6 matched with a grinder packing, and the end surface of the other side of the circular fixture body (2) is provided with a positioning hole phi 7 matched with an excircle phi 5 of a work piece (1) and three screw holes used for clamping a pressure plate (3). The circular fixture body (2) is additionally provided with a radial groove convenient to clamp the work piece. A middle hole phi 8 is arranged in the radial direction of the circular fixture body (2). A nut (4) is screwed up, and the work piece (1) is fastened on the circular fixture body (2) through the pressure plate (3). The fixture has the advantages that since the fixture only needs to aligned once during mounting, the processing efficiency and the product accuracy are greatly improved; and when a middle hole phi 2 and a taper hole phi 3 and a taper hole phi 4, which are inner holes, are processed, the excircle phi 5 is simultaneously processed, so that when an inner hole phi 1 is ground, the coaxiality of the inner hole phi 1, the middle hole phi 2, the taper hole phi 3, and the taper hole phi 4 is well guaranteed.
Description
Technical field
The utility model relates to a kind of lining inner hole grinding anchor clamps.
Background technology
Lining is the critical component of booster, mainly plays the effect that connects main shaft and compressor impeller, plays important effect when booster is worked, and is therefore very high to the requirement of this part.
For this part difficulty maximum be exactly the axiality that guarantees endoporus φ 1, interstitial hole φ 2 and taper hole φ 3-φ 4, and the axiality of endoporus φ 1 and cylindrical φ 5.
Because the design feature of this part is that interstitial hole φ 2 is little, endoporus φ 1 is big on the left side, and taper hole φ 3-φ 4 is also big on the right, therefore adding man-hour for guaranteeing the axiality of three endoporus, must and add strict control in man-hour in jig Design.For guaranteeing the axiality requirement of three endoporus, original processing method is after the fine finishining, at first grinds left side endoporus φ 1, then with this endoporus location cylindrical grinding, centering processing interstitial hole φ 2 and the right taper hole φ 3-φ 4 on lathe at last.The shortcoming theme of this processing method have following some:
It is bad that 1 machining accuracy guarantees, needs artificial centering during owing to processing interstitial hole φ 2 and the right taper hole φ 3-φ 4, and error is big.
2 working (machining) efficiencies are low, and artificial centering need to adjust repeatedly, so working (machining) efficiency is low.
The protection of 3 pairs of workpiece is unfavorable, because workpiece is in the end before the machined into, cylindrical grinds, and therefore adds man-hour on lathe, and the clamping cylindrical damages workpiece easily.
Summary of the invention
For solving above technical problem, the utility model provides a kind of lining inner hole grinding anchor clamps that guarantee the axiality of endoporus φ 1, interstitial hole φ 2 and taper hole φ 3-φ 4.
This lining inner hole grinding anchor clamps, one side end face of circular clamp body is provided with the endoporus φ 6 that matches with the grinding machine packing, the opposite side end face is provided with the locating hole φ 7 that matches with excircle of workpiece φ 5, this end face also is provided with 3 screw holes that are used to clamp pressing plate, also be provided with the radial groove of being convenient to clamping work pieces on the circular clamp body, the circular clamp body is provided with axial interstitial hole φ 8, and fastening nut is fastened on workpiece on the circular clamp body by pressing plate.
The utility model advantage is: only need a centering when installing owing to anchor clamps, working (machining) efficiency and product precision have been improved greatly, clamping workpiece utilizes endoporus φ 7 end face grooves of circular clamp body to locate to these anchor clamps, the pressing plate workpiece pressing, grinder part endoporus φ 1, because when processing interstitial hole φ 2 and taper hole φ 3-φ 4 endoporus, cylindrical φ 5 is also simultaneously processed, be interstitial hole φ 2, taper hole φ 3-φ 4, the axiality of cylindrical φ 5 is guaranteed, therefore when mill endoporus φ 1, well guaranteed the axiality of endoporus φ 1 with interstitial hole φ 2, taper hole φ 3-φ 4.
Description of drawings
Fig. 1 is the Workpiece structure schematic diagram.
Fig. 2 is a circular clamp body structure schematic diagram.
Fig. 3 is a lining inner hole grinding clamp structure schematic diagram.
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described: Fig. 1 in, workpiece 1 is provided with endoporus φ 1, interstitial hole φ 2 and taper hole φ 3-φ 4 from left to right, and cylindrical φ 5.The design feature of this part is that interstitial hole φ 2 is little, and endoporus φ 1 is big on the left side, and taper hole φ 3-φ 4 is also big on the right.Specification requirement to this part is the axiality that guarantees endoporus φ 1, interstitial hole φ 2 and taper hole φ 3-φ 4, and the axiality of endoporus φ 1 and cylindrical φ 5.
In Fig. 2 Fig. 3, at first workpiece 1 is wanted fine finishining, earlier interstitial hole φ 2 and the right taper hole φ 3-φ 4 is processed on lathe, and these two endoporus adopt a clamping processing, can guarantee axiality well.Because when processing interstitial hole φ 2 and taper hole φ 3-φ 4 endoporus, cylindrical φ 5 is also simultaneously processed, i.e. interstitial hole φ 2, taper hole φ 3-φ 4, the axiality of cylindrical φ 5 is guaranteed.Utilize the utility model lining inner hole grinding anchor clamps again, with this workpiece 1 clamping to the endoporus grinding machine.One side end face of circular clamp body 2 is provided with the anchor clamps endoporus φ 6 that matches with the grinding machine packing, the opposite side end face is provided with the locating hole φ 7 that matches with excircle of workpiece φ 5, this side end face also is provided with 3 screw holes that are used to clamp pressing plate 3, also be provided with the radial groove of being convenient to clamping work pieces on the circular clamp body 2, circular clamp body 2 is axially arranged with interstitial hole φ 8, and fastening nut 4 is fastened on workpiece 1 on the circular clamp body 2 by pressing plate 3.Packing location, precision height are adopted in circular clamp body 2 and lathe coupling part.Circular clamp body 2 endoporus φ 6 are connected with the grinding machine packing, have guaranteed the coaxial of anchor clamps and machine tool chief axis, and circular clamp body endoporus φ 7 matches with workpiece 1 cylindrical φ 5, and 3-φ 24 screw holes are used to place pressing plate 3, so as clamping work pieces 1, grinder part 1 endoporus φ 1.Circular clamp body 2 endoporus φ 7 are used to locate workpiece 1, and the axial interstitial hole φ 8 of circular clamp body 2 leaves groove in the middle of this circular clamp body 2 and is convenient to clamping work pieces as the lathe cooling-water duct.
