Technical field

The invention belongs to Machining of Shaft-type Parts fields, and in particular to a kind of axial workpiece screw thread clamps striking gear and its adds Work method.

Background technique

In engine part process, certain important parts need to detect its physicochemical property, and Physico-chemical tests work exists Play an increasingly important role further in the manufacturing process of aero-engine and status, more and more important parts need into Row dissection is decomposed, and after the sampling work for completing part, carries out relevant physical and chemical project detection.The round stretching examination of certain machine high temperature alloy Part finished product is as shown in Figure 1, M1 is the external screw thread of M14 × 2, and there is centre bore at both ends, and the external screw thread at this both ends has concentricity requirement, Intermediate roundlet column diameter D is Ф 6, when processing both ends external screw thread, is positioned using two center holes, is clamped with lathe universal fixturing Part drives universal fixturing rotation to machine part by machine chuck.When clamping large cylindrical, lathe universal fixturing It unclamps, is put into part and steps up threaded one end, process other end screw thread；When lathe universal fixturing clamps external screw thread, spiral shell can be weighed wounded Line, turn around entrucking when, intermediate roundlet shell of column can only be clamped, first have to adjustment universal fixturing grasping part, make big end M14 × 2 It is threaded through, then 6 outer circle of clamping Ф is processed, and waits after processing is completed, fixture is unclamped and is greater than M14 outer circle, is then taken Sample out, it is time-consuming and laborious；Since mid diameter is smaller, only Ф 6, the torsional forces that when processing generates makes test piece deformation, test specimen matter Amount not can guarantee.To shorten the process-cycle, guarantee product quality, it is necessary to improve existing processing method.

Summary of the invention

It is an object of the invention to be directed to above-mentioned the problems of the prior art, a kind of clamping of axial workpiece screw thread is provided and is stirred Device and its processing method greatly promote efficiency when the round tensile test specimen of high temperature alloy processes both ends screw thread, guarantee sample Preparation quality, effectively shorten manufacturing cycle needed for engine important part Physico-chemical tests project, safe operation, conveniently.

To achieve the goals above, the technical solution adopted by the present invention are as follows:

Including matrix, the matrix opens up first through hole at the position close to upper end, can install cylinder in first through hole Pin, is between the two transition fit；Matrix opens up the first internal thread hole along first through hole side, installs cone in the first internal thread hole Holding screw is held, the tapered end of tapered end holding screw penetrates straight pin, and it is firm to guarantee that straight pin is connect with matrix；It is opened in the middle part of matrix If semicircle internal thread hole, semicircle internal thread hole match with the round tensile test specimen external thread part of high temperature alloy；Matrix is half The square hole penetrated through therewith is opened up below round internal thread hole, briquetting is installed in square hole；The bottom surface of matrix opens up spiral shell in third upwards Pit, housing screw is installed in third internal thread hole, and housing screw passes through third internal thread hole and is connected with briquetting.

The upper surface for the square hole that the middle part of matrix is opened up is higher than center 0.5mm~1mm of semicircle internal thread hole.

Matrix installs baffle in the side of square hole, and matrix is opened up in the lower part two sides of square hole there are two the second internal thread hole, Slotted countersunk flat head screw is installed in second internal thread hole, offers on the baffle and matches with slotted countersunk flat head screw at two Screw via hole.

Matrix uses up-small and down-big special-shaped plate, and baffle uses rectangular slab, and the thin wall thickness of baffle is 3mm~3.1mm.

The tapered end holding screw, slotted countersunk flat head screw, straight pin are all made of national sector standard part.

The briquetting by cutting matrix square hole when the square stock that generates be process, briquetting and matrix uniform thickness, on briquetting End face offers the briquetting semicircle internal thread hole to match with the semicircle internal thread hole of matrix.

Housing screw is turret head housing screw, and housing screw includes thread rod part, taper top and is connected to screw thread Bar portion and taper top between transition bar portion, taper top extend into briquetting, transition gauge diameter be less than taper top and Thread rod part.

Briquetting internal thread hole identical with third internal thread hole is offered on the briquetting, is offered in briquetting than pressure The annular groove of the big 2mm~2.2mm of block internal thread hole major diameter, taper top are placed in annular groove, and annular groove depth H 1 is than housing screw Taper come directly towards the big 1mm~1.2mm of length H4, annular groove top surface to the distance between briquetting end face H2 than housing screw taper come directly towards with Small 1mm~the 1.5mm of the sum of the length of transition bar portion H3, a part of transition bar portion are exposed in briquetting.

The processing method that axial workpiece screw thread of the present invention clamps striking gear, it is characterised in that:

Step 1: straight pin is mounted on matrix, and fastened by tapered end holding screw, housing screw is passed through into third Internal thread hole is mounted on matrix, and housing screw passes through third internal thread hole and screws in the briquetting on matrix；

Threaded one end processing is completed Step 2: first clamping test specimen lathe universal fixturing, when turning around clamping test specimen, Housing screw is rotated counterclockwise, briquetting is driven to move downward, axial workpiece screw thread clamping striking gear is inserted in test specimen Screw thread position, then it is rotated clockwise housing screw, it drives briquetting to move upwards, compresses test specimen external screw thread；

It is fixed Step 3: screw thread will be mounted on and clamp the test specimen on striking gear with machining tool, the outer spiral shell of the processing other end Line.

First by the center hole of screw thread end face be packed into machining tool scroll chuck center it is top on, and make the side of straight pin Then gear makes the top of the top insertion test specimen other end on processing machine tailstock top in the side of any one claw of scroll chuck It is held out against in hole.

Compared with prior art, the present invention is with following the utility model has the advantages that using matrix, briquetting, tapered end holding screw, circle The mode of the components Split assembled such as pin and housing screw be arranged the axial workpiece screw thread clamp striking gear, can at the scene into Row dismounting, using flexible, axial workpiece screw thread clamping striking gear of the invention solve the round tensile test specimen of high temperature alloy and add The problem of processing efficiency is low, quality not can guarantee when the screw thread of work both ends greatly shortens engine important part Physico-chemical tests Project manufacturing cycle averagely can improve 50% than the efficiency of previous installation way, ensure that sample prepares matter by actual measurement Amount makes the whole manufacturing cycle time of part Physico-chemical tests project shorten 10%, and screw thread of the present invention clamps the knot of striking gear Structure is compact, and processing method is easy to operate, reliable clamping, ensure that the safety of the processing quality and process of test specimen.
