Abstract
The utility model discloses a gear milling frock, which comprises a shaft sleeve, a cone seat and a pull rod. The shaft sleeve is connected with the cone seat. The axial directions inside the shaft sleeve and the cone seat are respectively provided with through troughs communicated with each other. The pull rod is arranged in the through trough of the cone seat. The axial direction inside the pull rod is provided with a groove communicated with the through trough of the shaft sleeve. The shaft sleeve comprises an outer cone sleeve and a centering clamping device. The centering clamping device is arranged on the inner side of the outer cone sleeve. The centering clamping device is arranged in the shaft sleeve, thus, after a gear with a handle is arranged in the gear milling frock, the front section of the shaft handle of the gear is clamped and centered by the clamping device to eliminate a gap between the shaft handle of the gear and the shaft sleeve and the matching gap of the gear with the handle and the frock is arranged at the rear section of the shaft handle of the gear so that the tooth runout can be reduced by half when the gear with the handle is processed and the qualified rate of products is greatly increased.
Description
Technical field
The utility model relates to a kind of Gear Processing anchor clamps, particularly a kind of mill teeth frock that is used to process the conical gear of various band handles.
Background technology
Accurate hyperbola conical gear is a lot of a kind of part that automobile is used, and is divided into bull wheel and steamboat, and wherein the steamboat majority is the axial workpiece of band handle.Manufacturer is when the conical gear of this type of band handle of processing, the general processing tool as shown in Figure 1 that adopts carries out mill teeth, mainly comprise axle sleeve 1, awl seat 2 and pull bar 3, its bottom bracket axle 1 is connected with awl seat 2, in axle sleeve 1 and awl seat 2, have groove 4a and the groove 4b that is interconnected on axial, pull bar 3 is arranged among the groove 4b of awl seat 2, axially be provided with the groove 5 that is communicated with axle sleeve 1 groove 4a in the pull bar 3, adopt the slope shape faying face that cooperatively interacts in the joint portion of awl seat 2 and pull bar 3 front ends.To be with handle gear 9 to insert in the mill teeth frock, gear head is resisted against fixed its axial location of end face of axle sleeve, the leading portion of gear footstalk is felt relieved by axle sleeve, the pulling pull bar, because the faying face of slope shape between pull bar and the awl seat, when pull bar pulled back, its head can push to the centre, thereby the rear end of gear footstalk is clamped and centering, thereby product is processed.
Yet, because band handle gear is in the process of inserting the mill teeth frock, be matched in clearance between gear footstalk and the axle sleeve, this belt transect handle gear could be encased in the frock smoothly, so, can have 0.01～0.02 gap between gear footstalk and the axle sleeve all the time, also there is 0.005～0.01 nonconcentricity in the frock endoporus in addition, therefore in reality processing, the product tooth runout that processes can cause the defective of product existence 30% like this between 0.02～0.06.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of and prevent to be with the handle gear man-hour to occur tooth runout adding, thereby improve the mill teeth frock of product percent of pass greatly.
The technical solution of the utility model is achieved in that a kind of gear mill teeth frock, comprise axle sleeve, awl seat and pull bar, axle sleeve is connected with the awl seat, in axle sleeve and awl seat, have two grooves that are interconnected on axial, pull bar is arranged in the groove of awl seat, axially be provided with the groove that is communicated with the axle sleeve groove in the pull bar, it is characterized in that: described axle sleeve comprises external conical sleeve and centering and clamping apparatus, and centering and clamping apparatus is arranged on the external conical sleeve inboard.
Gear mill teeth frock described in the utility model, its described centering and clamping apparatus comprises positioning sleeve and spring ringfeder, positioning sleeve is connected with external conical sleeve, the positioning sleeve front end is low early and high after ramped shaped, described spring ringfeder is arranged on the positioning sleeve inboard, its front end is the low ramped shaped in preceding high back that is complementary with positioning sleeve front end shape, and the rear end of spring ringfeder is connected with pull bar, and external conical sleeve is connected with the awl seat successively with positioning sleeve.
The utility model is by being provided with centering and clamping apparatus in axle sleeve, band handle gear its footstalk leading portion after the mill teeth frock of packing into is clamped and centering with regard to clamped device, eliminated the gap between gear footstalk and the axle sleeve, the fit clearance of band handle gear and frock is placed on the back segment of gear footstalk, thereby band handle gear can reduce half adding the man-hour tooth runout, and product percent of pass increases greatly.
Description of drawings
Fig. 1 is the schematic cross-section of existing mill teeth frock.
Fig. 2 is a schematic cross-section of the present utility model.
Mark among the figure: 1 is axle sleeve, and 2 are the awl seat, and 3 is pull bar, and 4a, 4b are for being groove, and 5 is groove, and 6 is external conical sleeve, and 7 is positioning sleeve, and 8 is the spring ringfeder, and 9 are band handle gear.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 2, a kind of gear mill teeth frock, comprise axle sleeve 1, awl seat 2 and pull bar 3, axle sleeve 1 is connected with awl seat 2, have groove 4a and the groove 4b that is interconnected on axially in axle sleeve 1 and awl seat 2, pull bar 3 is arranged among the groove 4b of awl 2, axially is provided with the groove 5 that is communicated with axle sleeve 1 groove 4a in the pull bar 3, described axle sleeve 1 comprises external conical sleeve 6 and centering and clamping apparatus, and centering and clamping apparatus is arranged on external conical sleeve 6 inboards.
Described centering and clamping apparatus comprises positioning sleeve 7 and spring ringfeder 8, positioning sleeve 7 is connected with external conical sleeve 6, positioning sleeve 7 front ends are low early and high after ramped shaped, described spring ringfeder 8 is arranged on positioning sleeve 7 inboards, its front end is the low ramped shaped in preceding high back that is complementary with positioning sleeve 7 front end shapes, be loose fit between positioning sleeve 7 and the spring ringfeder 8, the rear end of spring ringfeder 8 is threaded with pull bar 3, and external conical sleeve 6 is connected with awl seat 2 successively with positioning sleeve 7.
To be with handle gear 9 to insert in the mill teeth frock, gear head is resisted against fixed its axial location of end face of external conical sleeve, the pulling pull bar, the spring ringfeder moves under the drive of pull bar backward, because being equipped with of spring ringfeder and positioning sleeve front end slope shape faying face, spring ringfeder front end can push to the centre, thereby the front end of gear footstalk is clamped and centering, eliminated the gap between gear footstalk and the axle sleeve, the fit clearance of band handle gear and frock has been placed on the back segment of gear footstalk, like this, band handle gear add the gear ring in man-hour beated little half, product percent of pass increases greatly.
