Abstract
The utility model relates to a line-contact straight bevel gear positioning body, which comprises a straight bevel gear and a gear positioning body, wherein the gear positioning body and the straight bevel gear are in a straight line contact from bigger ends to smaller ends; and the extension line of the contact line of the gear positioning body and the straight bevel gear passes through a reference cone apex. In the utility model, the gear positioning body and the straight bevel gear can be reliably positioned; the line-contact straight bevel gear positioning body is applicable to being used as a clamping device or a detecting tool in mass production, can be conveniently machined and manufactured and can guarantee the product quality and improve the production efficiency.
Description
Technical field
The utility model relates to gear positioning device, and especially a kind of location is reliable, the spur bevel gear positioning body that uses as clamp body or cubing in being adapted at producing in enormous quantities.
Background technology
Automobile differential uses very extensive with spur bevel gear, in batch process, mainly contain machining and precision forging dual mode, these two kinds of processing modes finally all need be with tooth portion location processing installed surface, endoporus, as planetary sphere, axle shaft gear sphere or cylindrical, end face need the positioning body of design specialized to be used for processing, to detect.
In order to realize location processing installed surface with tooth portion, need the design specialized positioning body to realize effectively location, could guarantee the machining accuracy of product.Traditional positioning body design uses the product profile of tooth to process as electrode discharge usually, use the flank of tooth that overlaps fully with the product profile of tooth flank of tooth as locating surface, contact the location with product realization face, because locating surface overlaps fully with the flank of tooth, positioning accuracy is very sensitive to positioning body mismachining tolerance and product error, need carry out long hand lapping to positioning body and could satisfy instructions for use.
The utility model content
At the deficiency of above existing spur bevel gear positioning body, the purpose of this utility model provides a kind of processing method of spur bevel gear positioning body, and passes through the gear positioning body that this processing method obtains.This gear positioning body is used for fixing and when processing spur bevel gear, form line between positioning body and the spur bevel gear and contact, and the positioning body location is reliable, is adapted at using as clamp body or as cubing in the production in enormous quantities.
The purpose of this utility model is achieved by the following technical solution:
Line contact spur bevel gear positioning body comprises spur bevel gear and gear positioning body, and when being in contact with one another between described gear positioning body and the spur bevel gear, the gear positioning body linearly contacts from the big small end of holding with spur bevel gear.
As optimal technical scheme of the present utility model, the extended line of contact wire is crossed reference cone apex between described gear positioning body and the spur bevel gear.
The beneficial effects of the utility model are: with respect to prior art, the utility model gear positioning body linearly contacts from the big small end of holding with spur bevel gear, and the extended line of contact wire is crossed reference cone apex.The location is reliable between gear positioning body and the spur bevel gear, is useful in the production in enormous quantities as clamp body, or uses as cubing.The utility model processing and manufacturing is convenient, can guarantee the quality of converted products, has improved production efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The processing method of line contact spur bevel gear positioning body, this method may further comprise the steps:
(1) tooth profile parameter of the spur bevel gear of processing as required uses three-dimensional graphics software to draw the threedimensional model of described spur bevel gear positioning body profile of tooth;
(2) the control interface of the described positioning body profile of tooth of use finite element process simulation system simulation makes between described spur bevel gear and its positioning body and does not produce interference;
(3) three-dimensional modeling data with described positioning body profile of tooth is converted into the machining center lathe parameter, the procedure of establishment positioning body;
(4) base is lathed described positioning body blank with lathe with suitable bar;
(5) adopt machining center to rough mill described positioning body blank, make it form the positioning body profile of tooth;
(6) heat treatment is heat-treated the positioning body blank that above-mentioned processing step obtains, to increase the hardness of described positioning body;
(7) cylindrical of the described positioning body of grinding and end standard;
(8) adopt the described positioning body profile of tooth of machining center finish-milling, make the tooth profile parameter of positioning body reach the requirement of step (1);
(9) finished product of the described positioning body of acquisition is in order to using.
In the present embodiment, described step (1) is to use the three-dimensional graphics software of UG to draw the threedimensional model of described spur bevel gear positioning body profile of tooth; Described step (2) is to use the control interface of the described positioning body profile of tooth of Deform finite element process simulation system simulation, makes between described spur bevel gear and its positioning body and does not produce interference.Present embodiment contacts through forming straight line between positioning body that above-mentioned processing step obtained and the spur bevel gear, and the extended line of contact wire is crossed reference cone apex between gear positioning body and the spur bevel gear.
As shown in Figure 1, line contact spur bevel gear positioning body, comprise spur bevel gear 1 and gear positioning body 2, when being in contact with one another between described gear positioning body 2 and the spur bevel gear 1, gear positioning body 2 linearly contacts from the big small end of holding with spur bevel gear 1, and the extended line of contact wire is crossed reference cone apex 3 between described gear positioning body 2 and the spur bevel gear 1.
Claims (2)
1. a line contacts the spur bevel gear positioning body, comprise spur bevel gear and gear positioning body, it is characterized in that: when being in contact with one another between described gear positioning body and the spur bevel gear, the gear positioning body linearly contacts from the big small end of holding with spur bevel gear.
2. line contact spur bevel gear positioning body according to claim 1, it is characterized in that: the extended line of contact wire is crossed reference cone apex between described gear positioning body and the spur bevel gear.
