Abstract
The invention discloses a main shaft adjusting and locking device, relating to the field of machine manufacturing technology; the device comprises a left semi-circular block and a right semi-circular block; two ends of the left semi-circular block are provided with bosses, and two ends of the right semi-circular block are provided with grooves connected with the bosses in a matching manner; one end of the left semi-circular block is provided with a through hole that penetrates the boss of the end, and the other end is provided with a threaded hole; one end of the right semi-circular block, which is corresponding to the left semi-circular block, is provided with a through hole that penetrates the groove at the end, and the other end is provided with a threaded hole corresponding to the through hole of the boss of the left semi-circular block; two sides of the bosses at the two ends of the left semi-circular block are 15-degree draft surfaces, and the roughness Ra is 1.6; the two sides of the grooves in the right semi-circular block are 15-degree draft surfaces, and the roughness Ra is 1.6. The main shaft adjusting and locking device can solve the problem that during milling, when an adjustable pad consisting of the left semi-circular block and the right left semi-circular block has unbalanced stress in the axial direction, a locking bolt generates tangential deformation easily or even can be cut off.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of locking adjustment locking device adjusted for milling machine universal milling head main shaft position bearing and gear position.
Background technology
The universal milling head main shaft position compact dimensions of milling machine, in order to avoid frequently installing and removing high-precision bearing on main shaft and gear when equipment adjustment, ensures that main shaft bearing has good assembly precision, adopts traditionally and installs and removes conveniently semicircle adjustment lock pad structure; But this technology mainly has the following disadvantages: the adjusting pad directly half-and-half cut open, if the adjusting pad axially loaded be operationally cut open is uneven, can only be balanced by the frictional force of adjusting pad cut surface; If main shaft is when heavy cut, because main shaft impulsive force is comparatively large, and the reason such as lathe vibrations, the frictional force of binding face is not enough, adjusting pad easily loosens and misplaces up and down, now the clamping screw by adjusting pad is born shearing to make up the deficiency of binding face frictional force; That tangential deformation easily occurs is even cut-off bearing for a long time under strong shearing stress for bolt, and not easily finds.
Summary of the invention
The object of this invention is to provide a kind of main shaft adjustment locking device, its adjusting pad of being made up of left semicircle ring block and right semi-circle ring block when can solve milling of this main shaft adjustment locking device is when axially loaded is uneven, and the problem that tangential deformation is even cut off easily occurs clamping screw.
In order to solve the problem, the technical solution used in the present invention is:
This main shaft adjustment locking device, include the left semicircle ring block and right semi-circle ring block that can mutually fasten: described left semicircle ring block two ends is provided with boss, described right semi-circle ring block two ends is provided with the groove matched with described boss; Described left semicircle ring block one termination is provided with the through hole running through this end boss, and another termination offers screwed hole; A described right semi-circle ring block termination corresponding with described left semicircle ring block screwed hole is provided with the through hole running through this end groove, and another termination offers the screwed hole corresponding with the through hole of described left semicircle ring block boss.
In above technical scheme, further scheme is: the two sides of described left semicircle ring block two ends boss are 15 ° of withdrawing pattern faces, roughness Ra 1.6; Described right semi-circle ring block upper groove two sides are 15 ° of withdrawing pattern faces, roughness Ra 1.6.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is rubbed stressed by the forward of male and fomale(M&F) stressed replacement by binding face, can carry larger axial unbalanced load, and possess higher rigidity and stability.
2, the clamping screw of adjusting pad that the present invention is made up of left semicircle ring block and right semi-circle ring block does not bear tangential force, and only bear axial force, reliability is higher.
3, the boss both sides of left semicircle ring block of the present invention and the groove both sides of right semi-circle ring block are 15 ° is withdrawing pattern face, can play guiding, increasing frictional force and precise positioning effect when assembling.
4, left semicircle ring block of the present invention and right semi-circle ring are divided into left and right two half blocks by the annulus after integrally machining by Linear cut, reconditioning axial width after integral locking during use, Installation and Measurement is convenient, avoids frequently installing and removing accurate main shaft and precision bearing, guarantees main shaft precision.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
The main shaft adjustment locking device of Fig. 1 and Fig. 8, includes the left semicircle ring block 1 and right semi-circle ring block 2 that can mutually fasten; As shown in Figures 2 and 3, left semicircle ring block 1 two ends is provided with boss, and shown in Fig. 4, Fig. 5 Fig. 6 and Fig. 7, right semi-circle ring block 2 two ends is provided with the groove matched with described boss; Left semicircle ring block 1 one termination is provided with the through hole running through this end boss, and another termination offers screwed hole; Right semi-circle ring block 2 termination corresponding with left semicircle ring block 1 screwed hole is provided with the through hole running through this end groove, and another termination offers the screwed hole corresponding with the through hole of left semicircle ring block 1 boss.
The two sides of left semicircle ring block 1 two ends boss are 15 ° of withdrawing pattern faces, roughness Ra 1.6; Right semi-circle ring block 2 upper groove two sides are 15 ° of withdrawing pattern faces, roughness Ra 1.6.
In use, the raised line of left semicircle ring block is inserted in the groove of right semi-circle ring block, carry out guiding by the inclined-plane of raised line and the inclined-plane of groove fasten and use bolt tightening, be clamped on main shaft 3, select suitable one adjusting pad 6, then tighten spindle locking nut 7, can conveniently to the bearing 5 on main shaft 3, gear 4 part carries out the adjustment of axial dimension precision, has again Rigidity and strength well simultaneously, ensure that the reliability requirement of mechanism.
