During implementation, the present invention because emery wheel 4 and the fit precision of knife bar 5 height, fit clearance small (fit clearance is in
0.003mm~0.012mm), it is slightly off during assembling will be stuck, so must there is a support to ensure whole assembling process
It is linear motion when middle emery wheel 4 assembles relatively with knife bar 5；The present invention will consider the confined state of emery wheel 4, scene
Packing ring is often loaded onto on knife bar 5 to fix the rigging position of emery wheel 4 as needed, so the guide pillar (screw shaft 2) of assembling
Stroke must long enough；When the present invention is to assemble 4 time of emery wheel, it is laborsaving, conveniently, without by instrument manually with regard to energy
Complete；The present invention is directed need the object acted on by external force, it is contemplated that installation fixation problem.
More than technical scheme of some assembling device formed as shown in Figure 1, 2, including seven parts, dotted portion
It is the schematic diagram of emery wheel 4, knife bar 5 and packing ring confined state, the architectural characteristic and function of each part are respectively：
Base 1：It is the foundation of the present apparatus, plays support and fixed effect, (be connected by screw with screw shaft 2
Part 8) connection, fixed above that anti-conversion straight pin (rotation preventing device 9) two pieces coordinated with knife bar 5 is housed, its face N is whole device
Reference plane, and two wide mounting grooves of 17mm (installation slotted eye 12) are left, it can be installed on the table by screw.Base 1 has
There is wear-resisting performance, for a set of base 1 can be shared with provision for disengagement, devise φ 100 cylinder locating surface.
Screw (connector 8)：It is universal standard part, shares three, plays a part of connect base 1 and screw shaft 2.
Straight pin (rotation preventing device 9)：It is universal standard part, shares two pieces, coordinate with the knife bar 5 of emery wheel 4, play anti-rotation
Effect.
Sleeve 3：It is the pressure and position portion of the present apparatus, sleeve 3 contacts (such as Fig. 1) with emery wheel 4 in M faces, to protect
Demonstrate,prove the best straight line motion state of emery wheel 4 and knife bar 5.As shown in figure 1, the positioning external diameter of the endoporus of sleeve 3 and knife bar 5 is matched somebody with somebody
Gap is 0.01mm~0.015mm, is not more than 0.005mm with the non-perpendicularity in M faces, the nonparallelism of upper surface and M faces is necessary
No more than 0.01mm.To ensure the assembling stroke of emery wheel 4, the work effective depth of sleeve 3 have to be larger than the installation of knife bar 5
Length.Not damage the soft matrix of emery wheel in assembling process, M faces diameter is necessarily less than the inner ring steel bushing of emery wheel 4
Diameter.For ease of observation confined state and loss of weight, make four peep holes (observation window 6) on body, there is wear-resisting performance,
And there is certain rigidity.
Screw shaft 2：It is the targeting part of the present apparatus, is connected by screw (connector 8) with base 1, through emery wheel
Knife bar 5, top is screw thread, more handle nuts 11 rotated thereon pressure pressing plate 10 transported downwards with moving sleeve 3 and emery wheel 4
It is dynamic, so as to reach the purpose of assembling.To ensure the assembling stroke long enough of the emery wheel of various confined states, its effective length
It has to be larger than the overall length of 2 times of knife bars 5.
Pressing plate 10：It is the force transmission member of the present apparatus, there is certain rigidity.
More handle nuts 11：It is universal standard part, with respect in general tightening nut, is more beneficial for manually operated, convenient province
Power, play pressuring action.
Support positioning and fixing assembling device of the present invention by high-precision requirement, make use of knife bar 5 and emery wheel 4
Fit-up gap reaches the purpose of assembling, and principle is simple, easy to operate, after coming into operation, efficiently solves emery wheel 4 and assembles
The problem of difficult, the Operational preparation time is saved, and prevented to damage emery wheel 4 because assembling is improper.
The present apparatus can be arranged on one can stress horizontal table or ground on, to emery wheel 4 and knife bar 5 before assembling
Assembling assembly is cleaned, and removes unnecessary iron filings and dust, the component to be assembled by figure order, pressing plate 10 and more handles
Nut 11.When room temperature is relatively low, emery wheel 4 can be preheated with warm water before assembling, be more beneficial for assembling.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
