Description
【Technical field】
The present invention relates to countershaft-gear field of fixtures, more particularly to a kind of universal boring grab of countershaft-gear.
【Background technology】
" S " gearbox series of products almost cover all engines using torque section, with traditional main force to current
The long key positioning dress of box is different, and the jackshaft and countershaft-gear assembly method of " S " gearbox are that the positioning of pin hole formula is assembled.Become
Countershaft-gear type in fast case reaches more than 30 kinds, the clamp for machining of the key feature " pin hole " of gear, for tooth and pin hole
Position degree have strict requirements；And according to the assembly of product and use demand, there are three types of different for the pin hole of jackshaft plate gear
Theoretical position design requirement needed according to product requirement in the design process of boring grab, separately design positioning surface difference
Boring grab.In previous boring grab structure design, the versatility of fixture, an a set of folder of part are not accounted for
Tool, not only increases the design cost of fixture and this is made in throwing, and production speed is changed when also limiting product processing.
【Invention content】
The shortcomings that overcome the above-mentioned prior art, provides a kind of universal boring grab of countershaft-gear.The present invention is logical
Following technical scheme is crossed to realize：
A kind of universal boring grab of countershaft-gear, including pull rod, bipyramid ringfeder, mandrel, locating pad and to tooth gauge bottom
Plate；Pull rod is set to the through-hole of the inside of mandrel, and bipyramid ringfeder is installed in the tail portion of mandrel and pull rod；The heart is installed in tooth gauge bottom plate
The head front end of axis；Locating pad is installed in the head rear end of mandrel.
The present invention, which further improves, to be：
Circumference side in the middle part of the mandrel is equipped with groove.
Pull rod tail portion is equipped with spindle tail for both fixed dowel hole.
Locating pad is plain cushion.
Locating pad is cross open pad.
Locating pad is not opening supports pad.
Compared with prior art, the present invention has technique effect beneficial below：
The universal boring grab of countershaft-gear provided by the invention, by changing the structure of ringfeder, mandrel, and increase
Adjusting pad, it is multigroup tooth gauge mandrel is used cooperatively, improve flexibility, the versatility of fixture, while having reached the production of fast quick change,
Efficiency is improved, reduces design and throw that this purpose is made.
【Description of the drawings】
Fig. 1 is a kind of universal boring grab front view of countershaft-gear provided by the invention；
Fig. 2 is 3 kinds of embodiments of the locating pad in the universal boring grab of a kind of countershaft-gear provided by the invention
Front view；
Fig. 3 is three kinds of positioning method of the tooth space centerline of countershaft-gear.
Wherein：1- bipyramid ringfeders；2- mandrels；3- locating pads；4- is to tooth gauge bottom plate；5- pull rods；31- plain cushions；32- crosses are opened
Mouth pad；33- not opening supports pads.
【Specific implementation mode】
Invention is described in further detail below in conjunction with the accompanying drawings, according to Fig. 1 and Fig. 2, a kind of countershaft-gear is universal
The installation steps of boring grab are as follows：
1) the dividing head working surface stood on oil (gas) filling device, is cleared up, each piece surface of fixture is cleared up, is filled successively on dividing head
Enter to tooth gauge bottom plate 4, mandrel 2, bipyramid ringfeder 1 and pull rod 5, holder for correcting is jumped with end by examining the diameter of each working surface to jump
Tool.The present invention uses bipyramid ringfeder, tensioner effect good；Ringfeder length is shortened, to allow cutter groove design to leave position in mandrel
It sets；Bonding ringfeder can be made, the pitch-row versatility of fixture is enhanced.Groove, product pin bore axis are equipped in the middle part of central shaft of the present invention
Become larger to adjusting range, improves fixture versatility；Circumferencial direction adjusting range becomes larger, and improves fixture versatility；Chip removal effect is good.
2), corresponding locating pad 3 is chosen by the corresponding piece surface of the tooth space centerline of product；Tooth socket according to fig. 3
Center line O, P and Q select plain cushion 31, cross open pad 32 and not opening supports pad 33 respectively, and are packed into fixture mandrel 2, correct
It jumps at end.The present invention uses the design of seriation locating pad, at present the transverse tooth thickness variation range of all " S " gearbox jackshaft plate gears
Between 28-33mm, the design axial dimension of dowel hole changes in the range of 25-33mm, thus to the height of tooth gauge away from
From what is be to determine, keep it corresponding with ringfeder, required according to the theoretical size of different product, adjust the thickness of locating pad, it is fixed to change
The structure of position pad, makes it while meeting the processing of the part of different tooth space centerline theoretical values, increase the versatility of fixture, realizes
The quick change of part is processed.
3) it, is packed into tooth gauge, and can flexibly twitch by the corresponding mandrel 2 of the teeth portion parameter selection of product.By to tooth gauge
Coordinate with locating pad 3 and adjust, when different products processes switching, reaches fast quick change production.
4) it, presses technological requirement and adjusts dividing head angle, blow off inner bore of part and be inserted in 1 ringfeder of bipyramid ringfeder, it is desirable that positioning
Face fits closely, live spindle 2 be inserted into tooth socket, operation lathe tensile ties 5 and check part whether tensioner, as clamping properly if
Start to process.
5) it, is reported by the CMM Data of initial workpiece, adjusts dividing head angle, meet technological requirement in position degree
Afterwards, start Continuous maching.
The above content is merely illustrative of the invention's technical idea, and protection scope of the present invention cannot be limited with this, every to press
According to technological thought proposed by the present invention, any change done on the basis of technical solution, in claims of the present invention
Within protection domain.
