Description

To tooth-like bevel gear shaft cutting fixture
Technical field
The utility model relates to a kind of fixture of locating milling bevel gear shaft, and specifically, the utility model relates to a kind of to tooth-like bevel gear shaft cutting fixture.
Background technology
Shaping by stock removal is one of main technique realizing bevel gear shaft suitability for industrialized production, when actual cutting, in order to reach High-efficient Production and accurately to produce, will implement respectively roughing and fine finishining operation for the bevel gear shaft that modulus is relatively large.Do will carry out tooth the workpiece of installing before finish-milling tooth, very important to tooth operation, otherwise follow-up milling easily causes colored tooth, grinds one's teeth and the quality accident such as transverse tooth thickness attenuation.The industry is existing mainly contains two kinds to tooth technology, apply maximum a kind of be tooth gauge to be arranged on the head of a bed of milling machine, what adopt that elastic extension structure installs can retract to installation site to tooth gauge after to tooth, so that implement follow-up Gear Milling.Another kind is on jig main body, to be provided with teeth groove to tooth technology, to tooth gauge take to teeth groove as benchmark is to tooth, after workpiece is determined position, remove tooth gauge, so that implement follow-up cutting processing.The former is fixing to tooth method, and its advantage is that clamp body can design compactlyer.Because clamp head length is pressed workpiece to be machined size and fixed, the Lg of clamp body can be enough little.But supporting milling machine table stroke L is fixed value, adds clamp body processing length Lg and be less than L, so the scope of processed gear is wider.However, fixing is to the shortcoming of tooth method also clearly the head of a bed of supporting milling machine to tooth gauge reference for installation, and position is relatively fixing.And workpiece rotates, while stopping, position is unfixing, in order to make workpiece have a definite position, conventionally adopts approach switch, and limit switch or cam mechanism are rotated spacing.But the reliability of matched with electric equipment, environment temperature, milling machine power etc. all can produce spacing error, thereby affect accurate positioning, even locate failure.The second uses teeth groove is located tooth gauge tooth method, because teeth groove is located on clamp body, constant with the workpiece relative position of clamping, thereby overcomes the above-mentioned fixing deficiency to tooth method.Equally, the second is to tooth method also Shortcomings, and problem is on clamp body, to increase by one to teeth groove, must increase clamp body processing length Lg, in the situation that supporting milling machine table stroke L is constant, has reduced the scope of machining gears.In addition, all there is potential safety hazard in prior art, and the former must check the reliability of spring, while never allowing workpiece to rotate with fixture part to the sagging cutter accident of hitting that causes of tooth gauge.The latter's potential safety hazard is must take off tooth gauge before cutting, otherwise throws away casualty accident when tooth gauge is rotated with workpiece.
Utility model content
The utility model is mainly for the deficiencies in the prior art, propose a kind of simple in structure, accurate positioning, easy to loading and unloading, use safety and do not reduce the processed range of gears of supporting milling machine to tooth-like bevel gear shaft cutting fixture.
The utility model is achieved through the following technical solutions technical goal.
To tooth-like bevel gear shaft cutting fixture, it comprises the head of a bed, main shaft, clamp body, ball stud and chuck.Described clamp body is hollow shaft, and axis of cone section is inserted in the inner cone hole of main shaft of the milling machine head of a bed, and the end face junction of clamp body waist shoulder and main shaft links into an integrated entity with bolt.The cantilever end of clamp body is provided with seam and coordinates with chuck and do coaxial connection.Its improvements are: the external conical sleeve that described chuck is built-in through hole, the tapering of chuck is identical with the taper direction of workpiece bevel gear, external conical sleeve smaller diameter end is less than the root diameter of the large end of workpiece, and larger diameter end outer wall is provided with ring groove, is provided with a radial hole in ring groove.Described ball stud is setting element, and with bulb outwardly, cylindrical section is inserted in the radial hole in ring groove ball stud inwardly, the external location structure to tooth gauge of the common formation of ball stud and ring groove.
Ring groove axial cross section in said structure is rectangle, and straight-flanked ring groove is convenient to machined and is shaped, and is also convenient to tooth gauge to locate.
The utility model compared with prior art, has following good effect:
1, the location structure being coordinated by ring groove and ball stud is simple, to tooth gauge handling easily, and accurate positioning;
2, milling machine table stroke L is greater than clamp body processing length Lg, does not reduce the scope of supporting milling machine machining gears;
3, ring groove is located on chuck and rotates with clamp body, there is no relative motion, swift to operate to tooth;
4, tooth gauge is located by the ball stud being arranged in ring groove, bulb accurate positioning, easy to tooth, easy to loading and unloading, be that each part position is fixed on the other hand, safe and reliable to operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments, further illustrate the utility model below.
The bevel gear shaft processing for automobile drive axle to tooth-like bevel gear shaft cutting fixture shown in Fig. 1, it comprises the head of a bed 1, main shaft 2, clamp body 3, ball stud 4 and chuck 5.Described clamp body 3 is hollow shaft, plays location and supporting role in structure, and axis of cone section is wherein inserted in main shaft 2 internal taper holes of the milling machine head of a bed (1), and the end face junction of clamp body 3 waist shoulders and main shaft 2 links into an integrated entity with bolt.Clamp body 3 is exposed at cantilever end outside main shaft 2 and is provided with seam and coordinates with chuck 5 and do coaxial connection.The external conical sleeve that described chuck 5 is built-in through hole, endoporus coordinates with workpiece 6 shaft parts, the tapering of chuck 5 is identical with the taper direction of workpiece 6 bevel gears, external conical sleeve smaller diameter end is less than the root diameter at workpiece 6 large end places, larger diameter end outer wall is provided with ring groove 5.1, in the present embodiment, ring groove 5.1 axial cross sections are rectangle, are provided with a radial hole in ring groove 5.1.Described ball stud 4 is as setting element in the utility model, and its installation site is in the radial hole of the built-in ring groove 5.1 of chuck 5.When installation, with bulb upward, cylindrical section is inserted in the radial hole of ring groove 5.1 ball stud 4 down, and both are interference fit.Ball stud 4 and the external location structure to tooth gauge 5.2 of ring groove 5.1 common formation, will be inserted into position to tooth gauge 5.2 during to tooth, complete taking off tooth gauge 5.2 after tooth, proceed to normal Gear Milling.In the utility model, be directly arranged in chuck for the ring groove 5.1 that tooth gauge 5.2 is located, milling machine table length L is greater than clamp body 3 processing length Lg, so do not reduce the scope of supporting milling machine machining gears.The heaviest is in the utility model, tooth gauge 5.2 to be located, and adopts bulb location, to tooth gauge 5.2 accurate positionings, easy to tooth, easy to loading and unloading, is that each component locations is fixed on the other hand, safe and reliable to operation.
