Abstract
The invention provides a fixture for repeatedly turning and repairing an external thread by using a horizontal lathe simply, safely and precisely and a clamping method thereof. A poking disc fixture consists of four ejecting bolts and a U-shaped groove; a poking disc tool is fixed on a workpiece through the four ejecting bolts; the workpiece is supported by lathe head and lathe tail tips in the workpiece clamping; and the poking disc tool is connected to one clamping jaw of the lathe for transferring a torque through the U-shaped groove. After a thread of the workpiece is roughly machined, a horizontal turning chuck is locked to link with a tool post; and the workpiece and the poking disc fixture are dismounted from equipment for premounting. When the workpiece is horizontally turned again, the workpiece is also fixed by the horizontal turning lathe head and lathe tail tips; and the clamping jaw used in the first clamping process is adjusted to enter the U-shaped groove of the poking disc tool to finish the second clamping process; and the second fitting of the thread can be directly performed without alignment for a workpiece thread machining initial angle after clamping.
Description
Technical field:
The present invention relates to one utilize horizontal lathe repeatedly car repair externally threaded fixture and clamping method thereof
Background technology:
The design of AP1000 conductive screw for turbogenerator rotor have employed a kind of off-gauge remodeling Hui Shi canalis spinalis screw thread.Because this canalis spinalis screw thread does not have datum level measurer, add man-hour requirement and first carry out roughing, again by pre-installing with conducting rod intraspinal tube screw thread, and according to prepackage result, secondary repair being carried out to contact screw canalis spinalis external screw thread, being threaded into the degree of depth with what reach drawing requirement.Do not discharge the prerequisite of clamping at workpiece under, the mode double thread that horizontal lathe can be linked by locking knife rest and chuck carries out secondary repair.Once workpiece leaves lathe, again during clamping, accurately cannot recover the start angle of workpiece screw thread process, admittedly secondary repair cannot be realized.This product is because needing with addition of work, and workpiece must be pre-installed after roughing, then carries out screw thread repair.Based on above-mentioned background, be badly in need of a kind of brand-new fixture of research and development and clamping method, to realize the externally threaded secondary repair processing of contact screw canalis spinalis.
Summary of the invention:
The object of this invention is to provide a kind of fixture and installation way of more accurate, more convenient, external screw thread secondary repair that versatility is stronger.Technical scheme of the present invention is: driver plate fixture (1) is made up of four puller bolts (2) and a U-lag (3), by four puller bolts (2), driver plate instrument (1) is fixed on workpiece (4), be connected on lathe claw (5) by driver plate instrument (1) by U-lag (3), its clamping method is:
1) driver plate fixture (1) is sleeved on workpiece (4), utilizes puller bolt (2) driver plate fixture (1) and workpiece (4) to be fixed;
2) utilize the sleeping carriage head of a bed top (6) and tailstock top (7), the workpiece (4) installing driver plate fixture (1) is fixed on sleeping carriage;
3) turning of work piece (4), the U-lag (3) of driver plate instrument (1) is made to aim at upper one of them claw (5) of sleeping car chuck (8), adjustment sleeping carriage claw (5), claw (5) is entered in the U-lag (3) of driver plate instrument (1), completes clamping;
4), after roughing, locking sleeping car chuck (8) and sleeper knife rest link, and are together pulled down by workpiece (4) together with driver plate instrument (1);
5) when sleeping carriage gone up again by workpiece (4), the same use sleeping carriage head of a bed top (6) and tailstock top (7) fixation workpiece (4), and the claw (5) used during adjustment first time clamping, make to complete secondary clamping in its U-lag entering driver plate instrument (1), do not need the start angle of centering workpiece (4) screw thread process after clamping, directly can carry out the secondary repair processing of screw thread.
Operation principle:
After one of them claw of sleeping car chuck is connected with workpiece by driver plate instrument, workpiece circumferencial direction angle is relative with sleeping car chuck angle fixing.During operation sleeping carriage, after locking chuck rotates and links with knife rest feeding, be equivalent to have locked workpiece rotation simultaneously and link with knife rest feeding.Under this operating mode, even if taken off from sleeping carriage by workpiece, do not taking off the driver plate instrument on workpiece, under not removing the prerequisite that sleeper knife rest feeding and chuck link, when again carrying out clamping, use same dog transmission, still can return to the machining angle before release clamping.
Technique effect:
Lathe adopts chuck claw clamping workpiece, during Vehicle Processing external screw thread, although the mode that locking knife rest and lathe chuck can be adopted to link repeatedly car repair the pitch diameter of thread, the whole process of the Vehicle Processing of screw thread must complete by clamped one time.Traditional processing mode, workpiece, once leave lathe, cannot recover start angle during screw thread process again during clamping, so cannot realize pre-install after with addition of work.By application the present invention, provide simpler, safer, the more accurate installation way of one, after solving the processing of workpiece external screw thread, secondary clamping centering screw thread process start angle problem, what solve odd-pitch screw central diameter smoothly joins processing problems with addition of work and water pipe thread screw-in depth.
Accompanying drawing illustrates:
Fig. 1: driver plate fixture schematic diagram.
Fig. 2: clamping workpiece schematic diagram.
Detailed description of the invention:
1) a driver plate fixture 1 as shown in Figure 1, is designed and produced.Driver plate fixture 1 internal diameter is greater than workpiece 4 fixed position external diameter, uniform four puller bolts 2 of fixture circumferencial direction, and has the U-lag 3 that a width dimensions is greater than sleeping carriage claw 5.
2) driver plate instrument 1 is sleeved on workpiece 4, screws four puller bolts 2 and driver plate instrument 1 is fixed on workpiece 4.
3) as shown in Figure 2, the workpiece 4 having installed driver plate instrument 1 is placed in the centre of gyration line position of sleeping car chuck 8, needs one end of machining screw towards tailstock workpiece 4.Make that the head of a bed is top 6, the center hole of tailstock top 7 alignment pieces 4 both ends of the surface respectively, workpiece 4 is fixed on sleeping carriage by adjustment top 7 positions of tailstock.Rotate sleeping car chuck 8, make one of them claw 5 aim at U-lag 3 on driver plate instrument 1, after marking this claw 5, adjustment claw 5 makes it stretch in U-lag 3.
4) lock sleeping car chuck 8 to link with sleeper knife rest, start sleeping carriage and carry out externally threaded roughing.After processing, mobile sleeping dead center 7, together pulls down workpiece 4 together with driver plate instrument 1, carries out the prepackage of workpiece 4.The driver plate instrument 1 on workpiece 4 can not be pulled down in pre-process of assembling.
5) according to prepackage result, sleeping carriage cutting depth is readjusted.3 require clamping workpiece again according to the order of sequence, and the claw 5 of mark is stretched in U-lag 3 again, as shown in Figure 2.
6) start sleeping carriage and secondary repair is carried out to workpiece external screw thread.
