Abstract
The utility model provides a gear cutting jig which comprises a gear clamping seat and a core fixing shaft. The gear clamping seat is in the shape of a flower bud and arranged at the upper end of the core fixing shaft, a shaft mounting hole is formed in the top of the gear clamping seat, a plurality of longitudinal grooves distributed in an array are formed in the side face of the gear clamping seat in the circumferential direction, and the longitudinal grooves are communicated with the shaft mounting hole. Accordingly, in the whole cutting process, the gear cutting jig can firmly clamp and fix a gear, the structure is simple, production is easy, and using is convenient. The taper of the lateral edge of the gear clamping seat is 15 degrees, workpiece clamping force is greatly enhanced, the gear can not loose in the heavy cutting process, cutting precision is guaranteed, the yield of gears in the manufacturing process is improved, rework and scrapping are reduced, and cost is lowered. A longitudinal clamping groove is formed in the side face of the core fixing shaft to be connected with a clamping block on a cutting machine in a clamped mode, the core fixing shaft is effectively prevented from moving in the cutting process (especially the heavy cutting process), cutting precision is further improved, and the yield is higher.
Description
[technical field]
The utility model belongs to Gear Production equipment technical field, particularly a kind of cutting tool for axle type gear.
[background technology]
At present, on market, existing gear cutting machine all can be provided with clamping fixture, as the cutting clamping fixture of axle type gear (spiral bevel gear), some tools or complex structure, produce, use inconvenient, that have or clamping dynamics is inadequate, fixed effect is poor, very easily occurs loosening at working angles (especially in the time heavily cutting), have a strong impact on cutting accurately, cause the gear of this processing procedure good low, rework rate and scrappage are high, have greatly improved production cost.
[utility model content]
In order to solve the above-mentioned technical problem existing in prior art, the utility model provides a kind of piece-holder power strong, gear grips effective, effectively improve cutting accuracy and acceptance rate, reduce and do over again and scrap, reduce costs, and simple in structure, be easy to produce cutting tool easy to use.
The technical scheme that the utility model solution prior art problem adopts is:
A kind of cutting tool, includes gear grip slipper and centering spindle; Described gear grip slipper is bud shape, and is located at the upper end of centering spindle, and its top is provided with axle installing hole, and peripheral side is provided with the longitudinal grooved of some array distribution, and described longitudinal grooved is connected with axle installing hole.
Further, the monolateral tapering of described gear grip slipper is 15 °.
Further, the side of described centering spindle is provided with at least one longitudinal draw-in groove.
Further, the width of described longitudinal draw-in groove is 4mm, and the degree of depth is 1.5mm.
Further, described gear grip slipper and centering spindle are one-body molded.
The beneficial effects of the utility model are as follows:
The utility model, by technique scheme, can firmly be clamped gear at whole working angles, simple in structure, is easy to produce, easy to use; And the longitudinal grooved arranging strengthened the convergent force of gear grip slipper widely, clamp, fixed effect is better.In addition, the monolateral tapering of gear grip slipper is 15 °, has greatly strengthened piece-holder power, ensures that in the time heavily cutting gear does not have yet at all loosening, cut accurately securely, has improved the gear acceptance rate of this processing procedure, and minimizing is done over again and scraps, and reduces costs; Simultaneously in the side of centering spindle, longitudinal draw-in groove is set, with the fixture block of the stock-removing machine clamping that is bonded with each other, effectively avoids being moved in working angles (especially heavily cutting process) centering spindle, further improved cutting accuracy, acceptance rate is higher.
[brief description of the drawings]
Fig. 1 is the structural representation of a kind of cutting tool embodiment described in the utility model;
Fig. 2 is the plan structure schematic diagram of a kind of cutting tool embodiment described in the utility model;
Fig. 3 is the cross-sectional view of a kind of cutting tool embodiment described in the utility model.
[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 to Fig. 3:
A kind of cutting tool described in the utility model implementation column, includes gear grip slipper 1 and centering spindle 2; Described gear grip slipper 1 is bud shape, and is located at the upper end of centering spindle 2, and one-body molded.Described gear grip slipper 1 top is provided with axle installing hole 11, peripheral side is provided with the longitudinal grooved 12 of some array distribution, described longitudinal grooved 12 is connected with axle installing hole 11, gear grip slipper 1 is divided into some equal portions (as Fig. 1, gear grip slipper 1 peripheral side is provided with the longitudinal grooved 12 that three channel arrays distribute, and gear grip slipper 1 is divided into three equal parts).Wherein, the monolateral tapering of described gear grip slipper 1 is 15 °.The side of described centering spindle 2 is provided with at least one longitudinal draw-in groove 21, and the width of described longitudinal draw-in groove 21 is 4mm, and the degree of depth is 1.5mm.
When cutting tool described in the utility model uses, first centering spindle 2 is fixed on stock-removing machine, then the gear shaft of axle type gear is inserted in axle installing hole 11, and live gear with the top braces of gear grip slipper 1.Like this, all gear firmly can be clamped carrying out whole working angles, simple in structure, be easy to produce, easy to use; And the longitudinal grooved 12 arranging strengthened the convergent force of gear grip slipper 1 widely, clamp, fixed effect is better.In addition, the monolateral tapering of gear grip slipper 1 is 15 °, has greatly strengthened piece-holder power, ensures that in the time heavily cutting gear does not have yet at all loosening, cut accurately securely, has improved the gear acceptance rate of this processing procedure, and minimizing is done over again and scraps, and reduces costs; Longitudinal draw-in groove 21 is set in the side of centering spindle 2 simultaneously, with the fixture block of the stock-removing machine clamping that is bonded with each other, effectively avoids being moved in working angles (especially heavily cutting process) centering spindle 2, further improved cutting accuracy, acceptance rate is higher.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
