Description

A kind of fixture of milling carbide alloy end face of shaft bush
Technical field
The utility model relates to the technical field of the fixture of fixing carbide alloy axle sleeve, particularly a kind of fixture of milling carbide alloy end face of shaft bush.
Background technology
Axle sleeve refers to the sleeve on propeller shaft or stern tube shaft.And bearing (Japan's person " axle is subject to ") plays parts that are fixing and reduction load coefficient of friction in mechanical transmission course.Axle sleeve generally plays sliding bearing effect.In order to save the wall thickness of the axial load design axle sleeve that material needs according to bearing, usually select cast copper or carbide alloy material.Axle sleeve can not bear axial load, maybe can only bear less axial load.
The end face of axle sleeve is normally pressed on on the shaft shoulder of main shaft on gear face, and for preventing gear from moving axially, therefore, the surface roughness requirements of end face of shaft bush is lower, to avoid damaging gear.At present, the axle sleeve of carbon steel or cast copper material is first gripped by vice, then milling cutter carries out Milling Process to the end face of axle sleeve on milling machine, thus carries out Milling Process to the axle sleeve of this material.But, for the axle sleeve of carbide alloy material, because carbide alloy axle sleeve intensity is high, hardness is high, cause in milling process, produce larger cutting force, this cutting force is much larger than the chucking power of vice, thus carbide alloy axle sleeve gets loose from vice, have a strong impact on the machining accuracy of carbide alloy end face of shaft bush, there is the unstable defect of fixing carbide alloy.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the fixture that a kind of compact conformation, fixing carbide alloy axle sleeve are firm, ensure the milling carbide alloy end face of shaft bush of high, the convenient taking-up product of carbide alloy end face of shaft bush Milling Accuracy.
The purpose of this utility model is achieved through the following technical solutions: a kind of fixture of milling carbide alloy end face of shaft bush, it comprises base and hold down gag, the top surface of described base is provided with boss, the top of boss is provided with the through hole being communicated with base basal surface, annular ring and gripper shoe is provided with in through hole, the top of annular ring is provided with spring, one end of spring is fixing on the annular rings, the other end of spring is fixing on the supporting plate, the top surface of described base is also provided with two screwed holes, two screwed holes are arranged on the both sides of boss, two screwed holes are all connected with hold down gag, described hold down gag is made up of threaded rod and pressing plate, threaded rod is connected with screwed hole, pressing plate is parallel to boss top surface and arranges, pressing plate is threaded with threaded rod, described gripper shoe is provided with and Lou considers hole to be worth doing.
Two described hold down gags are symmetrical arranged about boss.
Described gripper shoe is arranged perpendicular to through hole.
Described annular ring is arranged on the bottom of through hole.
The utility model has the following advantages: when (1) is set with carbide alloy axle sleeve in through hole, carbide alloy axle sleeve makes spring be compressed, after carbide alloy end face of shaft bush Milling Process completes, unclamp two hold down gags, carbide alloy axle sleeve has the trend moved upward under the effect of spring restoring force, avoiding axle sleeve is locked in through hole, takes out carbide alloy axle sleeve very convenient.(2) because carbide alloy axle sleeve can by the pressing plate of two hold down gags pushing down tightly, again because carbide alloy axle sleeve is inserted in through hole, thus limit the free degree of the six direction of carbide alloy axle sleeve, the cutting force produced when milling tool processing rigid alloy sleeve end face can not make greatly axle sleeve get loose again, therefore, fixing carbide alloy axle sleeve is very firm, thus ensure that the Milling Accuracy of carbide alloy end face of shaft bush.(3) gripper shoe of the present utility model is provided with and Lou considers hole to be worth doing, the material cut in milling carbide alloy end face process bits through leaking bits hole, annular ring outflow, ensure that and produce continuously successively.

Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1 or 2, a kind of fixture of milling carbide alloy end face of shaft bush, it comprises base 1 and hold down gag, the top surface of described base 1 is provided with boss 2, the top of boss 2 is provided with the through hole 3 being communicated with base 1 basal surface, carbide alloy axle sleeve is inserted in through hole 3, annular ring 4 and gripper shoe 5 is provided with in through hole 3, annular ring 4 is arranged on the bottom of through hole 3, gripper shoe 5 is arranged perpendicular to through hole 3, the top of annular ring 4 is provided with spring 6, and one end of spring 6 is fixed on annular ring 4, and the other end of spring 6 is fixed in gripper shoe 5.As shown in Figure 1 or 2, the top surface of base 1 is also provided with the both sides that two screwed holes, 7, two screwed holes 7 are arranged on boss 2, two screwed holes 7 are all connected with hold down gag, and two hold down gags are symmetrical arranged about boss 2.As shown in Figure 1 or 2, hold down gag is made up of threaded rod 8 and pressing plate 9, threaded rod 8 is connected with screwed hole 7, pressing plate 9 is parallel to boss 2 top surface and arranges, pressing plate 9 is threaded with threaded rod 8, because carbide alloy axle sleeve can by two pressing plates 9 pushing down tightly, again because carbide alloy axle sleeve is inserted in through hole 3, thus limit the free degree of the six direction of carbide alloy axle sleeve, the cutting force produced when milling tool processing rigid alloy sleeve end face cannot make axle sleeve get loose, fixing carbide alloy axle sleeve is very firm, thus ensure that the Milling Accuracy of carbide alloy end face of shaft bush.As shown in Figure 3, gripper shoe 5 is provided with and Lou considers hole 10 to be worth doing, the material cut in milling carbide alloy end face process bits flow out through leakage bits hole 10, annular ring 4 successively.
The course of work of the present utility model is as follows: as depicted in figs. 1 and 2, first carbide alloy axle sleeve is inserted in through hole, the downward pressing spring of carbide alloy axle sleeve, make the large step of carbide alloy axle sleeve lean against on boss simultaneously, tightening two pressing plates again makes two pressing plates be locked at the top of carbide alloy, thus achieve the vertical fixing of carbide alloy axle sleeve, then the end face of milling tool carbide alloy axle sleeve is used, after machining, unscrew pressing plate, axle sleeve moves upward under the effect of spring restoring force, thus fast carbide alloy axle sleeve is taken out, alleviate the labour intensity of workman.
The above is only preferred embodiment of the present utility model, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
