Abstract
The utility model relates to a high precision positioning lathe fixture for machining thin-wall disc sleeve parts, which comprises a fixture body installed on a main shaft connecting disc of a lathe, an oil cylinder installed at the other end of a main shaft of the lathe and a pull rod. An axial positioning disc is fixedly installed on the end face of the fixture. A positioning shaft sleeve is fixedly installed in an inner hole of the fixture body. A moveable positioning shaft base is arranged in the inner hole of the positioning shaft sleeve. One end of the positioning shaft sleeve is connected with an axial positioning shaft while a spring is arranged between the other end of the positioning shaft sleeve and an end cover of the positioning shaft sleeve. A pressure rod passing through the positioning shaft sleeve and the end cover is provided with a pressure plate matched with the axial positioning disc. The other end of the pressure rod is connected with the pull rod. The outer surface of the axial positioning shaft is cone-shaped. The positioning shaft base is provided with an oil injection channel for lubricating the positioning shaft base and the positioning shaft sleeve. The pressure rod is provided with an open washer and a spherical washer. With the adoption of the fixture to clamp parts, the clamping deformation is small and the positioning precision is high. Axial and radial precise positioning of parts can be realized at the same time. The lathe fixture is suitable for machining the thin-wall disc sleeve parts.
Description
Technical field
The utility model relates to a kind of jig, particularly a kind of high precision positioning lathe clamp of processing thin-walled disk cover parts use.
Background technology
In machine components processing, the processing of a lot of thin-walled disk cover parts is arranged, if use common scroll chuck clamping work pieces, clamping force can make part produce distortion, affect machining accuracy, the method that adopts at present normally adopts the mode of axial compression, but has the not high problem of radial location precision.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provides that a kind of to clamp distortion little, axially and the high turning attachment all of positioning accuracy radially.
The technical solution of the utility model is: a kind of turning attachment, comprise that being installed in machine tool chief axis connects the clamp body on the dish, the oil cylinder that is installed in the machine tool chief axis other end, pull bar, the axial location dish fixedly is housed on the clamp body end face, positioning shaft sleeve fixedly is housed in the clamp body endoporus, is provided with movably locating axle seat in the positioning shaft sleeve endoporus; One end of locating axle seat connects the radial location axle, the other end and be connected between the end cap of positioning shaft sleeve and be provided with spring; The depression bar that passes locating axle seat, end cap is provided with the pressing plate that cooperates with the axial location dish, the other end cylinder lever connecting rod of depression bar; Radial location axle outer surface is taper seat; Locating axle seat be provided with and positioning shaft sleeve between lubricated oiling road; Depression bar is provided with open washer and spheric washer.
The utility model has the advantages that: it is little and positioning accuracy is high 1, produce to clamp distortion; 2, can realize simultaneously part axial and accurate location radially, be applicable to the processing of thin-walled disk-like accessory.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of turning attachment, comprise that being installed in machine tool chief axis connects clamp body 4, the oil cylinder that is installed in machine tool chief axis 1 other end, the pull bar 2 that coils on 3, on clamp body 4 end faces axial location dish 6 is housed fixedly, in clamp body 4 endoporus positioning shaft sleeve 5 is housed fixedly, is provided with movably locating axle seat 7 in positioning shaft sleeve 5 endoporus; One end of locating axle seat 7 connects radial location axle 8, the other end and be connected between the end cap 14 of positioning shaft sleeve 5 and be provided with spring 13; The depression bar 12 that passes locating axle seat 7, end cap 14 is provided with the pressing plate 9 that cooperates with axial location dish 6, the other end cylinder lever connecting rod 2 of depression bar 12; Radial location axle 8 outer surfaces are taper seat; Locating axle seat 7 be provided with and positioning shaft sleeve 5 between lubricated oiling road 16; Depression bar 12 is provided with open washer 10 and spheric washer 11.
During work, workpiece 15 inner hole sleeves on radial location axle 8, because radial location axle 8 outer surfaces are cone, so that close contact between inner hole of workpiece and the radial location axle 8, are affected the radial location precision thereby eliminate because of the tolerance of locating hole.Locating axle seat 7 can move axially in positioning shaft sleeve 5, leans on the regulating action of spring 13 so that workpiece 15 end faces near positioning disk 6, have guaranteed the axial location precision.After workpiece installs, open oil cylinder work and drive pull bar 2 together with depression bar 12, pressing plate 9 clamping work pieces 15.After machining, oil cylinder is worked in the other direction and can be unclamped workpiece.
Claims (3)
1. turning attachment, comprise that being installed in machine tool chief axis connects the clamp body (4) on the dish (3), the oil cylinder that is installed in machine tool chief axis (1) other end, pull bar (2), it is characterized in that: on clamp body (4) end face axial location dish (6) is housed fixedly, in clamp body (4) endoporus positioning shaft sleeve (5) is housed fixedly, is provided with movably locating axle seat (7) in positioning shaft sleeve (5) endoporus; One end of locating axle seat (7) connects radial location axle (8), the other end and be connected between the end cap (14) of positioning shaft sleeve (5) and be provided with spring (13); The depression bar (12) that passes locating axle seat (7), end cap (14) is provided with the pressing plate (9) that cooperates with axial location dish (6), the other end cylinder lever connecting rod (2) of depression bar (12).
2. a kind of turning attachment according to claim 1, it is characterized in that: radial location axle (8) outer surface is taper seat; Locating axle seat (7) be provided with and positioning shaft sleeve (5) between lubricated oiling road (16).
3. a kind of turning attachment according to claim 1, it is characterized in that: depression bar (12) is provided with open washer (10) and spheric washer (11).
