Abstract
The utility model discloses a spindle adjusting and locking device, and relates to the technical field of machine manufacturing. The spindle adjusting and locking device comprises a left semi-circular-ring block and a right semi-circular-ring block. Bosses are arranged at the two ends of the left semi-circular-ring block, and grooves matched with the bosses are formed in the two ends of the right semi-circular-ring block. A through hole penetrating through the boss at one end is formed at the end of the left semi-circular-ring block, and a threaded hole is formed in the other end of the left semi-circular-ring block. The end, corresponding to the threaded hole of the left semi-circular-ring block, of the right semicircular ring block is provided with a through hole penetrating through the groove at the end of the right semi-circular-ring block, and a threaded hole corresponding to the through hole in the corresponding boss of the left semi-circular-ring block is formed in the other end of the right semi-circular-ring block. The two side faces of the boss at each end of the left semi-circular-ring block are 15-degree draft surfaces, and roughness is Ra1.6. The two side faces of the groove at each end of the right semi-circular-ring block are 15-degree draft surfaces, and roughness is Ra1.6. The spindle adjusting and locking device can solve the problem that in the milling process, a locking bolt is prone to tangential deformation and even is cut off when an adjustable pad composed of the left semi-circular-ring block and the right semi-circular-ring block bears unbalanced axial stress.
Description
Technical field
The utility model relates to machinery manufacturing technology field, especially a kind of locking adjustment locking device for milling machine universal milling head main shaft position bearing and gear position adjustment.
Background technology
The universal milling head main shaft position compact dimensions of milling machine, for fear of high-precision bearing and gear on frequent mounting or dismounting main shaft when the equipment adjustment, ensures that main shaft bearing has good assembly precision, adopt traditionally mounting or dismounting comparatively easily semicircle adjust lock pad structure; But this technology mainly has the following disadvantages: the adjusting pad of directly half-and-half cutting open, if the adjusting pad axially loaded imbalance being cut open in the time of work can only be carried out balance by the frictional force of adjusting pad cut surface; If main shaft is the in the situation that of heavy cut, because main shaft impulsive force is larger, and the reason such as lathe vibrations, the frictional force deficiency of binding face, adjusting pad is loosening dislocation up and down easily, now will bear shearing by the clamping screw of adjusting pad and make up the deficiency of binding face frictional force; Easily there is tangential deformation and be even cut off in bolt bearing for a long time under strong shearing stress, and is difficult for finding.
Utility model content
The purpose of this utility model is to provide a kind of main shaft and adjusts locking device, this main shaft is adjusted its adjusting pad of being made up of left semicircle ring piece and right semi-circle ring piece can solve milling time of locking device in the time that axially loaded is uneven, and the even cut problem of tangential deformation easily occurs clamping screw.
In order to address the above problem, the technical solution adopted in the utility model is:
This main shaft is adjusted locking device, includes left semicircle ring piece and the right semi-circle ring piece that can mutually fasten: described left semicircle ring piece two ends is provided with boss, and described right semi-circle ring piece two ends is provided with the groove matched with described boss; Described left semicircle ring piece one termination is provided with the through hole that runs through this end boss, and another termination offers screwed hole; A described right semi-circle ring piece termination corresponding with described left semicircle ring piece screwed hole is provided with the through hole that runs through this end groove, and another termination offers the screwed hole corresponding with the through hole of described left semicircle ring piece boss.
In above technical scheme, further scheme is: the two sides of described left semicircle ring piece two ends boss are 15 ° of withdrawing pattern faces, roughness Ra 1.6; Described right semi-circle ring piece upper groove two sides are 15 ° of withdrawing pattern faces, roughness Ra 1.6.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the utility model replaces by binding face friction stressedly by the forward of male and fomale(M&F) is stressed, can carry larger axial unbalanced load, and possess higher rigidity and stability.
The clamping screw of the adjusting pad that 2, the utility model is made up of left semicircle ring piece and right semi-circle ring piece does not bear tangential force, only bears axial force, and reliability is higher.
3, to be 15 ° be withdrawing pattern face in the groove both sides of the boss both sides of the utility model left semicircle ring piece and right semi-circle ring piece, in the time of assembling, can play guiding, increase frictional force and precise positioning effect.
4, left semicircle ring piece of the present utility model and right semi-circle ring are divided into left and right two half blocks by the annulus after one machines by line cutting, reconditioning axial width after integral locking when use, Installation and Measurement is convenient, avoid frequently installing and removing accurate main shaft and precision bearing, guarantee main shaft precision.
