Description
Technical field
The invention belongs to field of machining, patent is related to a kind of lathe process long bolt tooling.
Background technique
Commonly using screw rod is arrived in machining, finished product screw rod can be also bought in the market, only these screw surface screw threads
Quality is bad to be used as general civilian goods, and material is special material sometimes, and screw thread is nonstandard screw thread sometimes, at this moment
It needs to process long bolt with round steel.
The mode of processing long bolt adopts rolled thread and thread rolling more at present, this needs special equipment to be suitble to high-volume or specially sells enterprise
Industry.Support frame is then needed to assist one section of one section of processing resetting and its trouble using lathe process if small-scale use.And
The screw rod of special material or nonstandard screw thread is all to use on a small scale, in order to guarantee precision and save the cost, a kind of lathe is needed to add
The device of section chief's screw rod.
Summary of the invention
It is an object of the present invention to provide a kind of for lathe for resetting present in current techniques and precision deficiency
Process the device of long bolt.The design (or use) that the device follows round steel center mobile by screw die center, may be implemented to grow
Screw rod be processed and formed at one time and accuracy guarantee.
The technical solution of the present invention is as follows:
A kind of device for lathe process long bolt, composition include pedestal, outer snare, spring steel plate, interior snare, plate
Facing and screw die,
Wherein, the left end of the base is square plate, and center is provided with circular hole；Right end is cuboid bar；
The outer snare is annulus, is embedded in the circular hole of the left end of pedestal；The annulus is stepped ring forging, edge
Surrounding uniform intervals are provided with 12 dovetail grooves；
The both ends of the spring steel plate are dovetail key, and one end is mounted on outer ring and puts on, and the other end is mounted on inner ring and puts on；
The quantity of spring steel plate is 12；
The interior snare is annular, and outer ring surrounding uniform intervals are provided with 12 dovetail grooves, and inner ring surrounding is provided with 4 positioning
Hole, interior snare are placed on the step surface of outer snare；
Die sleeve is annular, and there are evenly spaced four positioning pins in outer ring, are fixed on inner ring and put on, inner ring is inlaid with plate
Tooth.
The invention has the benefit that
One end is stuck with three chucking chuck when the screw rod of current lathe process, since the other end with follow-rest choose button or
Person's screw die hitch is influenced cannot keep by round steel gravity with one heart to swing, spiral shell with that need to process spiro rod length and lengthen
Line quality will not be up to standard.And the present apparatus can make fixed screw die as round steel is swung, and remain screw die and be processed place
Round steel is concentric, eliminates and causes circumferencial direction stress by round steel swing, to guarantee thread quality.

Specific embodiment
The present invention is a kind of device for lathe process long bolt, and composition is as shown in Figs. 1-2, including pedestal 1, outer ring
2, spring steel plate 3, interior snare 4, die sleeve 5 and screw die 6 are covered,
Wherein, the pedestal 1 is as shown in figure 3, left end square plate, center are provided with circular hole, for inlaying outer snare
2, right end is cuboid bar, for being mounted on lathe saddle；The material of plate is aluminium sheet, with a thickness of 25mm；
The outer snare 2, with a thickness of 25mm, is embedded in the circular hole of the left end of pedestal 1 as shown in figure 4, for annular shape；
The annulus is stepped ring forging, and the diameter of big hole is 68mm, depth 20mm, and edge surrounding is uniformly provided with 12 dovetails
Slot matches with the dovetail key of 3 end of spring steel plate, and the diameter of small sircle hole is 18mm, with a thickness of 5mm, is used to add by round steel 7
The complete screw rod of work；
The spring steel plate 3 is as shown in figure 5, both ends are dovetail key, and centre is connected by thin slice, one end dovetail key and outer ring
Set 2 matches, and the other end matches with interior snare 4, there is the identical spring steel plate 3 of 12 shapes in whole device；Spring steel plate 3
Width with the width of interior snare 4, be 20mm.The interior snare 4 is as shown in fig. 6, for annular, and outer diameter 48mm is interior
Diameter is 38mm, and outer ring surrounding is uniformly provided with 12 dovetail grooves and matches with spring steel plate 3, and inner ring surrounding is uniformly provided with 4 positioning
Hole matches with die sleeve 5；Interior snare 4 is placed on the step surface of outer snare 2, passes through 12 spring steel plates and outer 2 phase of snare
Even.
Die sleeve 5 is as shown in fig. 7, for annular, and there are four positioning pins for the uniform protrusion of outer ring surrounding, including being fixed
On snare 4, inner ring is used to inlay screw die 6；Its outer diameter is 37mm, internal diameter 20mm, with a thickness of 10mm, for installing screw die 6；
It is as Figure 8-9 when use, device pedestal 1 is installed on lathe saddle, the lathe three chucking chuck of round steel 7 is pressed from both sides
Tightly.Lathe saddle auto-feed is adjusted, lathe is started.Screw die 6, die sleeve 5 and interior snare 4 are limited by spring steel plate 3 when hitch
It will not rotate, but can be moved in outer snare 2 with round steel 7, so that the moment guarantees that screw die 6 and the workshop section to be added of round steel 7 are concentric,
Guarantee thread quality.
Unaccomplished matter of the present invention is well-known technique.
