Abstract

The invention discloses a grinding clamping device for machining a high-strength countersunk shaft and an application method of the grinding clamping device. The grinding clamping device comprises a driving plate 1, a driving lever 2 and a clamping nut 3. The grinding clamping device and the application method have the advantages that technical problems of raw material waste, cockamamie working procedures, restrict tightened dimensional requirements on the working procedures, low production efficiency and the like in the prior art can be solved, and the grinding clamping device is simple in structure, low in production cost and convenient to use.

Description

A kind of grinding clamping device and method for using thereof of processing high strength countersunk head axle
Technical field
The present invention relates to a kind of grinding clamping device and method for using thereof of processing high strength countersunk head axle, belong to field of machining.
Background technology
Under normal conditions, use conventional method fine finishining when the cylindrical φ of heat treated countersunk head axle d2, need to stay the technology clamping to use lug at the countersunk head end, ability processing excircles φ d2, cylindrical fine finishining slices off the technology clamping again and uses lug after accomplishing; Or adopt two method of a system, after cylindrical fine finishining is accomplished, cut from middle and to be processed into two.No matter stay the technology clamping to use lug at the countersunk head end, still a system is two, in order to guarantee final size; In process, all want technology to add tight process dimension L1 and bevel angle α °, this has increased the difficulty of process; And because countersunk head axle hardness when fine finishining has reached HRC45~50 or higher; Turning cutting technique lug or cut into two and all compare difficulty, multiselect is used the line cutting processing, but the efficient of line cutting processing is very low.When one made two, axial dimension was wayward, need add the grinding end face one after the line cutting, to guarantee axial dimension.Former process one is the waste raw material; The 2nd, added sternly process dimension, increased difficulty of processing, quality is wayward; The 3rd, many a diatom cutting processing or grinding operations have reduced production efficiency.
Summary of the invention
The objective of the invention is to: for overcoming the defective that traditional diamond-making technique exists; A kind of grinding clamping device and method for using thereof of processing high strength countersunk head axle is provided, uses the present invention can save raw material, reduce manufacturing procedure; Shorten the production cycle, and the countersunk head axoplasm amount that processes is stable.
A kind of grinding clamping device of processing high strength countersunk head axle of the present invention is made up of dial 1, driving lever 2 and binding nut 3 three parts; There is a through hole at the center of dial 1; Thimble is passed through; The locating hole φ D of dial 1 plays coarse positioning than the big 0.3mm~0.8mm of countersunk head cylindrical φ d1 of countersunk head axle, dark 3mm~5mm, and this is convenient to clamping workpiece; Driving lever 2 is the screw rod of M8~M16, and length can push driving lever with the shifting block on the machine tool chief axis and be as the criterion; The flanging bevel angle of binding nut 3 is consistent with the countersunk head bevel angle of countersunk head axle, and in order to guarantee to add the security in man-hour, the clamping screw thread is a fine thread.
The method for using of grinding clamping device, it comprises the following steps:
As shown in Figure 2, be loaded on driving lever 2 in the screwed hole of dial 1, the countersunk head end of countersunk head axle is loaded among the locating hole φ D of dial 1; And clamp the countersunk head end of countersunk head axles with binding nut 3; Together be loaded on workpiece (countersunk head axle) and clamping device on the lathe with Double Tops pin location then, when lathe was worked, the shifting block on the machine tool chief axis can be stirred driving lever 2; Driving lever 2 drives clamping device and the rotation of countersunk head axle, thereby can grind processing or turning processing to the countersunk head axle.
Compared with prior art, the present invention locatees workpiece, processing excircles φ d2 with the Double Tops pin through clamping the countersunk head end place of countersunk head axle on lathe.Axial dimension L, countersunk head cylindrical φ d1 are able to respectively guarantee in two procedures, have reduced process dimension L1 and bevel angle α ° difficulty of processing, have reduced manufacturing procedure, have improved economy and production efficiency, and quality is easy to guarantee.
Description of drawings

Fig. 2 is a sketch map of the present invention
Among Fig. 2: 1. dial, 2. driving lever, 3. binding nut
The specific embodiment
Embodiments of the invention: combine Fig. 1, Fig. 2 to describe.
One, design grinding clamping device
The grinding clamping device is made up of dial 1, driving lever 2 and binding nut 3.
1, the centre bore of dial 1 is wanted to pass through thimble, and for weight reduction, the hole is big as far as possible, and locating hole φ D is than the big 0.3mm~0.8mm of countersunk head cylindrical φ d1 of countersunk head axle, dark 3mm~5mm.
2, driving lever 2 is the screw rod of M8~M16, and length can push driving lever with the lathe shifting block and be as the criterion.
3, the flanging bevel angle of binding nut 3 is consistent with the countersunk head bevel angle of countersunk head axle.In order to guarantee to add the security in man-hour, be processed into fine thread clamping screw thread.
Two, the technological method for processing of countersunk head axle:
1, gets the raw materials ready: the 40Cr bar.
2, Vehicle Processing:
(1) folder one end, face work, drill centers, car countersunk head cylindrical φ d1, cylindrical φ d2, chamfering and groove, countersunk head cylindrical φ d1 and cylindrical φ d2 made allowance, all the other size cars cut off to illustrating requirement.
3, heat treatment: quenching, temper reach hardness HRC45~50.
4, surface treatment: the processing of turning blue.
5, Vehicle Processing: grind the two ends centre bore.
6, grind processing (or turning processing):, on lathe, locate workpiece with the Double Tops pin with the end of leaning on of the cylindrical φ d2 that uses the heart carrier clamping work pieces always.Processing countersunk head cylindrical φ d1 guarantees α ° of bevel angle and jerk value r.
7, mill processing (or turning processing): with the countersunk head end of grinding clamping device clamping countersunk head axle of the present invention, with Double Tops pin location countersunk head axle (see figure 2), processing excircles φ d2 reaches the diagram requirement on lathe.
