The utility model discloses a special fixture for milling teeth of a long rack, which comprises a fixture body, a positioning hole 1 is arranged on the fixture body, and screws for fixing the fixture on the working table of a machine tool are respectively arranged on both sides of the fixture body One and screw two, the upper side of the clamp body is provided with a pressure plate through screw three. The utility model has the following features: the utility model is simple in structure, easy to use, small in size, easy to carry, can make ordinary small-range milling machines process long racks beyond its range, low production cost, long service life, and easy to popularize and use.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of long rack gear milling special fixture.
Background technology
Rackwork is divided into two kinds of spur rack and helical racks, and helical rack is divided into right tiltedly (revolving) and oblique (the revolving) two kinds in a left side by the skew direction of tooth again.Spur rack (i.e. tooth bar) tooth trace is perpendicular to the straight line of the direction of motion of tooth, and the direction of motion of helical rack (i.e. tooth bar) tooth trace and tooth has angle.Spur rack and helical rack include short tooth bar and two kinds of long tooth bars.
At present, for the processing of tooth bar, the classification of short tooth bar and long tooth bar does not have clear and definite boundary, just comes to a conclusion with the actual working ability of factory.Generally, the processing stroke of factory's plain-milling machine manufacturing gear strip surpasses 1 meter workpiece (structure is seen Fig. 4) below 1 meter and in actual production, run into tooth bar length, and general milling method can't be realized.In such cases, plant produced department can only cooperation processing, thereby can cause its production cost to improve greatly unavoidably, and crudy is uneven, even its delivery cycle also is difficult to guarantee.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of long rack gear milling special fixture is provided, and it is simple in structure; Easy to use, advantages of small volume is convenient to carrying; Can make common a small amount of journey milling machine processing exceed the long tooth bar of its range; Production cost is low, and long service life is convenient to promote the use of.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of long rack gear milling special fixture; Comprise clamp body; It is characterized in that: said clamp body is provided with locating hole one, and said clamp body both sides are respectively arranged with the screw one and screw two that is used to be fixed on the platen face, and said clamp body upside is provided with pressing plate through screw three.
Said screw one is the T-slot screw with screw two.
Be provided with pad between said screw one and screw two and the clamp body, be provided with pad between said screw three and the pressing plate.
The utility model compared with prior art has the following advantages:
(1) this long rack gear milling special fixture is simple in structure, uses very easy.
(2) this long rack gear milling special fixture volume is little, in light weight, is convenient to very much transportation.
(3) this long rack gear milling special fixture can make common a small amount of journey milling machine processing exceed the long tooth bar of its range, has reduced the production cost of factory.
(4) this long rack gear milling special fixture is convenient to produce very much, and long service life, is convenient to promote the use of.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.

The specific embodiment
A kind of long rack gear milling special fixture as depicted in figs. 1 and 2; Comprise clamp body 1; Said clamp body 1 is provided with locating hole one 1-1 that is used to limit processed tooth bar 7 positions; Said clamp body 1 both sides are respectively arranged with the screw 1 and screw 23 that is used to be fixed on the platen face, and said clamp body 1 upside is provided with the pressing plate 4 that is used for fixing and clamps processed tooth bar 7 through screw 35.
Like Fig. 1-shown in Figure 3, said screw 1 is the T-slot screw with screw 23.
Like Fig. 1-shown in Figure 3, be provided with pad between said screw 1 and screw 23 and the clamp body 1, be provided with pad between said screw 35 and the pressing plate 4.
The course of work of the long rack gear milling special fixture of the utility model is: the bottom surface of clamp body 1 that at first will long rack gear milling special fixture places on the platen; And its locating surface of centering; With T-slot screw 1 and T-slot screw 23 that clamp body 1 cramping is fastening; Processed tooth bar 7 as shown in Figure 4 is placed on the clamp body 1; Let the locating surface of processed tooth bar 7 and the locating surface of clamp body 1 be close to, and locating hole two 7-1 of tooth bar 7 are overlapped with locating hole one 1-1 of clamp body 1, insert rhombus alignment pin 8; Place the parallels 6 that has equal height with processed tooth bar 7 at clamp body 1 upside then, with pressing plate 4 and screw 35 processed tooth bar 7 is clamped and process.When being worked into the lathe range; Tooth bar 7 is unclamped, extract rhombus alignment pin 8, move processed tooth bar 7 its locating hole three 7-2 are overlapped with locating hole one 1-1 of clamp body 1; Insert rhombus alignment pin 8; Clamp processed tooth bar 7, can process remaining another section profile of tooth, so just accomplished the processing of whole tooth bar 7.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
