The through-hole of perforation axis is set, the clamp body is downwardly into the mounting hole of clamp bottom board, between clamp body and clamp bottom board
Positioning is connected with the indexing bolt of clamp bottom board through clamp body vertically by a pair of, and to penetrate through where axial end tooth
End, clamp body, clamp bottom board three's co-axially align the positioning pin the alignment of corresponding pin hole, and the interlude cylinder of clamp body
It is slidably matched with the mounting hole, so that tightening sleeve folder in the clamp body locking nut on clamp body third section cylinder
It can specifically move down and by clamp body axial compression on clamp bottom board.
The pressing plate includes vertical section and horizontal segment, and the lower face of vertical section is located on clamp body, and horizontal segment lower surface is taken
It is penetrating through where axial end tooth on the end face at end, horizontal segment is equipped between vertical section and perforation axis and is screwed into across horizontal segment
Bolt in clamp body.
Compared with the prior art, the utility model has the advantages that：
The axial restraint that perforation axis is realized by pressing plate is adapted to all uses without processing screw thread on perforation axis
The end face processing of identical shaft end has adapted to more products while reducing manufacturing procedure；It is realized using indexing bolt and positioning pin
The angle control of clamp body and perforation axis is easy to operate.
Part is illustrated to embody by the further advantage, target and feature of the utility model by following, and part will also pass through
Research and practice to the utility model and be understood by the person skilled in the art.
Description of the drawings
Fig. 1 is the vertical view of the utility model；
Fig. 2 is the A-A views of Fig. 1.
Specific implementation mode
In order to which so that the present invention is realized technological means, creation characteristic, reached purpose more understand and are apparent to effect,
The present invention is further elaborated with reference to the accompanying drawings and detailed description：
As depicted in figs. 1 and 2, the utility model proposes a kind of fixtures for processing perforation axial end tooth, including admittedly
Fixture base calmly on the table 7, clamp bottom board 1, clamp body 2, clamp body locking nut 6, indexing bolt 5,4 and of positioning pin
Pressing plate 3.
The clamp bottom board 1 is fixed in fixture base, and it is that height is higher to be placed vertically due to perforation axis, is unsuitable in work
Make 7 surface of platform and place processing, need to be processed outside workbench 7 so that the other end of shaft end can be less than workbench 7 where end-tooth
Surface, and then shaft end where end-tooth is allow suitably highly to be processed, so clamp bottom board 1 stretches out at least partially
7 surface of workbench, and extension is equipped with the mounting hole of installation folder specific 2.
The clamp body 2 is connected in sequence by three sections of cylinders of top-down decreasing radius, is equipped among clamp body 2
The through-hole of perforation axis is placed, the clamp body 2 is downwardly into the mounting hole of clamp bottom board 1, clamp body 2 and clamp bottom board
Positioning is connected through the indexing bolt 5 of clamp body 2 and clamp bottom board 1 vertically by a pair of between 1, and so that axial end will be penetrated through
End where tooth, clamp body 2,1 three's co-axially align of clamp bottom board the positioning pin 4 the alignment of corresponding pin hole, and clamp body 2
Interlude cylinder is slidably matched with the mounting hole, so that clamp body locking of the tightening sleeve on 2 third section cylinder of clamp body
The clamp body 2 can move down and by 2 axial compression of clamp body on clamp bottom board 1 when nut 6.
The pressing plate 3 includes vertical section and horizontal segment, and vertical end top is fixed with horizontal ends wherein one end, under vertical section
End face is located on clamp body 2, where horizontal segment lower surface rides over perforation axial end tooth on the end face at end, horizontal segment vertical section with
It is equipped with the bolt being screwed into across horizontal segment in clamp body 2 between perforation axis.When tightening the bolt, axial end stress is penetrated through
It clamps.
In said program, the installation process of the utility model is as follows：First by indexing pin hole and the fixture bottom on clamp body 2
The indexing pin hole alignment for installing indexing bolt 5 on plate 1, clamp body clamping screw 6 is screwed into simultaneously after being inserted into indexing bolt 5
It tightens so that clamp body 2 is firmly linked together with clamp bottom board 1, places into perforation axis and to upper for installing positioning pin 4
Dowel hole, is inserted into positioning pin 4, and placement pressing plate 3 is simultaneously tight by side pressure where the end-tooth for penetrating through axis by bolt.Pass through pressing plate 3
The axial restraint for realizing perforation axis is adapted to all endfaces using identical shaft end without processing screw thread on perforation axis
Reason has adapted to more products while reducing manufacturing procedure；The axial restraint that perforation axis is realized by pressing plate 3, without penetrating through
Screw thread is processed on axis, is adapted to all end face processings using identical shaft end, while reducing manufacturing procedure, has been adapted to more
Product；It is controlled using the clamping angle that indexing bolt 5 and positioning pin 4 realize clamp body 2 and penetrate through axis, easy to operate, adaptability
By force.
Further, the pressing plate 3 is two, and two pressing plates 3 are located at non-processing between the tooth group of adjacent both ends face
Region and the both ends for being located at the same diameter for penetrating through axial end.The end-tooth for penetrating through axis is two tooth groups for being mutually 70 degree of angles.
Two pressing plates 3 are mounted on the non-processing region of 110 degree of larger angles of two spaces, and are realized in same diametrically more stablize
Penetrate through the axial restraint of axis.
Further, the clamp body 2 is equipped with circular heavy platform, and end where end-tooth is located within the heavy platform and stretches
Go out the upper surface of the clamp body 2.Heavy platform facilitates the installation of the alignment and positioning pin 4 that carry out 4 place hole of positioning pin.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
