Abstract
The utility model discloses a bevel gear finishing cutting tooth positioning clamp. The bevel gear finishing cutting tooth positioning clamp comprises a positioning block, an insert, a pedestal, a pull rod and a disc-shaped spring, wherein an axial through hole used for mounting the pull rod is formed in the middle part of the plane of the pedestal; an ear block fixedly connected with the positioning block is arranged on the outer wall; the disc-shaped spring arranged in a workpiece inner hole is controlled through the pull rod to be deformed; the positioning block is a rectangular block in which a trapeziform taper hole is formed; one end of the insert is matched and positioned with the trapeziform taper hole of the positioning block through a trapeziform taper pin; and a positioning pin vertically arranged at the other end of the insert is matched and positioned with two bevel gears of a workpiece through a ball head end. When the workpiece is positioned, the pull rod moving leftwards compresses the disc-shaped spring, so the disc-shaped spring is deformed and expanded. The mounting position is a position where the finish machining allowances of the two side faces of the bevel gear are equal, so a base condition is created for the subsequent finish machining. A taper matching positioning and spherical alignment structure is adopted in the clamp, so the clamp is good in self positioning and high in repeated precision; and the clamp is simply operated, is high in working efficiency and is particularly suitable for mass production.

Background technology
When producing same kind bevel gear in enormous quantities, its tooth portion shaping by stock removal processing adopts substep cutting technology tissue to produce usually, and promptly first rough cut is processed, and remakes smart cut after staying the micro cutting surplus.Changing smart cut operation over to through the bevel gear semi-finished product of rough cut processing need reinstall, very little because of reserving allowance for finish, so want the installation site precision height of refinement cut.Otherwise it is uneven that installation deviation is prone to cause tooth two sides chipping allowance to distribute, and directly influences flank of tooth crudy.Prior art can be accomplished the even finishing tooth processing in tooth surfaces of bevel gears both sides through trying accurately centering installation site of cutter method.Although prior art is effective, every all inquires for positive installation site, length consuming time, and work efficiency is poor, can not satisfy batch production requirements.
The utility model content
The utility model is primarily aimed at the deficiency of prior art, proposes a kind of bevel gear finishing tooth positioning fixture that is provided with the location to toothing, and this clamp structure is simple, and contraposition is quick, accurate positioning.
The utility model is realized technical goal through following technical proposals.
Bevel gear finishing tooth positioning fixture, it comprises locating piece, plug-in unit, base, pull bar and disk spring.Said base is a disc-shaped component, and in-plane is provided with axially extending bore pull bar is installed, and is provided with a rectangle ear piece on the outer wall at least, the ear piece outwardly plane parallel in the axis of base.Said disk spring is built in the workpiece endoporus, runs through the pull bar axial displacement under external force of disk spring, directly controls the elasticity that cooperates of disk spring and workpiece endoporus.Its improvements are: said locating piece is established the rectangular block of trapezoidal taper hole in being, the plane parallel of trapezoidal taper hole is in the base lateral cross section, and the locating piece location and installation is on base rectangle ear piece outerplanar.Said plug main body is the square member; Long right-angle side free end is that trapezoidal taper pin directly is inserted in formation benchmark location structure in the trapezoidal taper hole of locating piece; The center line of the trapezoidal taper pin of corresponding long right-angle side is provided with the through hole on vertical this plane on the short right-angle side; The alignment pin that this through hole location and installation axially-displaceable is moving, alignment pin is inserted into workpiece awl tooth middle part formation to the tooth location structure with an end of bulb, and the other end is pieced together tight cushion block by nut and is constituted pull handle arrangement.
The tapering of trapezoidal taper pin of matching on built-in trapezoidal taper hole of locating piece and the plug-in unit in the said structure is 1:5～1:15.The bulb diameter of alignment pin equals the graduated arc transverse tooth thickness.
The utility model compared with prior art has following good effect:
1, plug-in type is to the tooth location structure, and is simple, be prone to make;
2, after the plug-in unit location, cooperate the location by the rough machined teeth groove of alignment pin and workpiece, accurate positioning, allowance for finish is reserved on uniform distribution tooth two sides, for smart cut has been created a basic condition;
3, taper fit location and sphere centering structure are easy to use, and self-align property is good, and repeatable accuracy is high;
4, Open architecture, easy and simple to handle, work efficiency is high.
Description of drawings
Fig. 1 is that the utility model structure master looks sketch map.
Fig. 2 is that sketch map is looked on Fig. 1 left side.
The specific embodiment
According to accompanying drawing and combine embodiment, the utility model is described further below.
That shown in Figure 1 is a kind of spiral bevel gear finishing tooth positioning fixture embodiment that is used for, and it comprises locating piece 1, plug-in unit 2, base 3, pull bar 4 and disk spring 5.Said base 3 is a disc-shaped component, and in-plane is provided with axially extending bore pull bar 4 is installed, and is provided with a rectangle ear piece on the outer wall at least, only establishes an ear piece in the present embodiment, the ear piece outwardly plane parallel in the axis of base 3.Locating piece 1 location and installation is on base 3 rectangular block outerplanars.Said disk spring 5 is the major parts that are used for workpiece 6 location swellings in the utility model; Disk spring 5 is built in workpiece 6 endoporus; Run through pull bar 4 axial displacement under external force of disk spring 5, directly control the elasticity that cooperates of disk spring 5 and workpiece 6 endoporus.Pull bar 4 is moved to the left among Fig. 2, the outer swelling workpiece 6 of disk spring 5 pressurized strains, on the contrary then loosen workpiece 6.Locating piece 1 is for to be located by connecting on the locating element on base 3 outer walls in the utility model, is to establish the rectangular block that tapering is the trapezoidal taper hole of 1:5～1:15 in a kind of, and tapering is 1:10 in the present embodiment, and the plane parallel of trapezoidal taper hole is in base 3 axial cross sections.Said plug-in unit 2 is another part locating elements of the utility model, and its main body is the square member, and long right-angle side free end is that trapezoidal taper pin directly is inserted in formation benchmark location structure in the locating piece 1 trapezoidal taper hole.The center line of the trapezoidal taper pin of corresponding long right-angle side is provided with the through hole on vertical this plane on the short right-angle side of plug-in unit 2; The alignment pin 2.1 that this through hole location and installation axially-displaceable is moving; Alignment pin 2.1 1 ends that insert workpiece 6 awl tooth middle parts are the bulb shape; The bulb diameter equals workpiece 6 awl tooth graduated arc transverse tooth thickness, and alignment pin 2.1 cooperates formation to the tooth location structure with workpiece 6 tooth portions.Alignment pin 2.1 other ends are formed pull handle arrangement by nut 2.2 and cushion block, are convenient to implement alignment pin 2.1 and insert definite installation site in the workpiece 6 awl teeth groove.
