Description
Technical field
The utility model relates to the large profile shaft of a kind of engine lathe, pipe part roughing alignment device, belongs to mechanical field.
Background technology
During with engine lathe roughing part outer and end face, traditional centering mode is that operator is by range estimation and experience, this method is doped with a lot of human factor, thus adds many uncertainties, and the height of operator's level of skill plays conclusive effect to centering result.If centering result is inaccurate, the lighter can have influence on the machining accuracy of part, severe one can cause because mismachining tolerance is too large the inside and outside circle of part eccentric serious, cannot remedy, thus make part rejection.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, easy to use, the centering large profile shaft of engine lathe, pipe part roughing alignment device intuitively.
Technical solution:
The utility model comprises: base, and for installing extension bar, extension bar is connected with slide bar one end, and the slide bar other end, for cutting flat structure, is cut flat position and is provided with the first rectangular channel; Also comprise scriber, be provided with the second rectangular channel in the middle part of scriber, scriber one end is folding acicular texture, and the other end is sharp acicular texture, and scriber realizes the movement on slide bar in the first rectangular channel by pinching screw and binding nut.
The described slide bar other end is Step Shaft structure, and the blind hole on the small end of Step Shaft and extension bar is matched in clearance.
The adjustment of scriber height:
The utility model is not when binding nut has complete pretension, scriber moves along with non-resistance in first rectangular channel of pinching screw on slide bar, after the complete pretension of binding nut, the relative position of scriber on slide bar is fixed, the change of scriber height can be realized, thus meet axle, the cylindrical of pipe part, the end face centering of various outer diameter size.
The adjustment of scriber angle and length:
The utility model is not when binding nut has complete pretension, and scriber can rotate around pinching screw axis, can move along the second rectangular channel of self simultaneously yet, after the complete pretension of binding nut, just can fix scriber length and self-view; Additionally by rotating rod, also can realize the rotation of scriber around slide bar axis, thus reach the object of different azimuth centering part.
Use of the present utility model, solves the difficult problem that the rough turn centering of part relies on human factor to determine completely, also makes centering operation have intuitive and Statistical simultaneously, thus ensure that the rough turn precision of part, improve working (machining) efficiency.

Detailed description of the invention
The utility model comprises: base 1, extension bar 2, slide bar 3, scriber 4, pinching screw 5, plain washer 6, spring washer 7, binding nut 8, soket head cap screw 9.
The utility model base 1 is provided with stepped hole, is provided with screwed hole in macropore bottom surface, and extension bar 2, through the stepped hole of base 1, is connected with base 1 by soket head cap screw 9; Extension bar 2 is provided with multidiameter, is provided with blind hole at the small end of multidiameter, middle part and base 1 matched in clearance; Slide bar 3 one end is provided with multidiameter, and the other end is provided with cuts flat structure, and the small end of multidiameter is placed in the blind hole of extension bar 2, cuts flat structure and is provided with the first rectangular channel 10; One end of scriber 4 is provided with folding acicular texture, the other end is provided with sharp acicular texture, middle part is provided with the second rectangular channel 11, and pinching screw 6 runs through the first rectangular channel 10 on slide bar 3 and the second rectangular channel 11 on scriber 4, is locked by scriber 4 by plain washer 6, spring washer 7 and binding nut 8.
The course of work:
One, chuck clamping parts
Chuck can not self-centering, and tailstock mushroom head is top can feel relieved, so after parts fixation, only needs centering part near the cylindrical of four claw sides.
The utility model is placed on lathe guide rail, according to the height of part installation site and the size of part outer size, regulate the height of scriber 4 on centering accessory, angle and length, the outer bowlder of centering uses scriber 4 folding acicular texture one end, uses scriber 4 acicular texture one end during centering end face.
Cylindrical centering: the initial distance of scriber 4 bent needle wedge angle and part outer is adjusted to about 10mm, low speed rotation chuck, the change of part outer and scriber 4 spacing is observed in part rotary course, high point (with scriber 4 apart near point) for part outer will adjust the lathe claw of correspondence position in good time, after often adjusting a claw, the distance of a scriber 4 bent needle wedge angle and part outer will be reduced.Repeat above operation, until scriber 4 is about 0.4mm with the distance of part outer, so far complete the centering operation of part outer.
End face centering: identical with the method for cylindrical centering.
Two, three-jaw chuck clamping parts
Three-jaw chuck is self-centering chuck, so after parts fixation, only needs centering part near the cylindrical of tailstock side.
Cylindrical centering: the initial distance of scriber 4 bent needle wedge angle and part outer is adjusted to about 10mm, low speed rotation chuck, the change of part outer and scriber spacing is observed in part rotary course, high point (with scriber apart near point) for part outer will knock part outer face or at corresponding lathe claw place pad copper sheet in good time, often adjust once, the distance of a scriber 4 bent needle wedge angle and part outer will be reduced.Repeat above operation, until scriber 4 is about 0.4mm with the distance of part outer, so far complete the centering operation of part outer.
End face centering: identical with the method for cylindrical centering.
