Lathe exists in a large number a kind of guide rail structure of dove-tail form, in the maintenance of equipment, owing to keeping in repair the requirement of precision, need to eliminate the gap between guide rail.According to dimension chain principle, a compensated loop must be there is, have when machine tool product manufactures a parts peculiar slide gib just to serve this effect.Slide gib, be a kind of parallel four limit type profile structures carve bar, be designed to be with the shape of gradient, be inserted between the guide rail that needs to coordinate, just effectively can eliminate the gap between guide rail.Panel may wear to a certain degree, must manufacture, could meet the contact precision of machine tool guideway with new panel.For ensureing contact precision, the mating surface of panel and dovetail guide needs to carry out scraping, but is all generally A, B face with hand scraping panel when manufacturing now, wasting time and energy, if replace hand scraping with grinding machine, is then a good method, but a set of frock must be designed, the requirement of processing could be met.
Summary of the invention
Technical problem to be solved by this invention is scraping fixture in a kind of machine upkeep of design, realizes the bonding tightness between lathe swallow-tail guide rail pair by this fixture.
For solving the problems of the technologies described above, the technical solution used in the present invention is: scraping fixture in a kind of machine upkeep, comprises upper body and lower body, and the upper surface of described upper body establishes dovetail guide; Described upper body is connected by eccentric shaft with same one end of lower body, and eccentric handwheel is established in one end of eccentric shaft, and the other end establishes fastening pinch wheels, on this end of upper body, establish at least one shop bolt; Establish positioning strip at the other end of upper body along upper body, positioning strip is established multiple locating hole.
In machine upkeep of the present invention, the using method of scraping fixture is:
(1). survey gap: inserted by panel in the guideway of lathe dovetail guide, measure the large end of panel or the gap of small end with clearance gauge, be recorded as M1;
(2). panel is located: take out panel, lain against by panel on the frock face, upper body of fixture, and panel ends contact shop bolt, with location, prevents panel from moving;
(3). clamping panel: by the multiple locating holes on positioning strip, regulate positioning strip, make positioning strip withstand panel, side then holds out against panel side with screw;
(4). measure, regulate: fixture entirety is placed on guideway of grinding machine, levelling with dial gauge, then, dial gauge is moved to the measuring junction of panel, gently eccentric adjustment handwheel, drive eccentric shaft turns, one end height of fixture is risen, after reaching M1 requirement according to dial gauge reading, screw down clips bearing up pulley;
(5). grinding panel: grinding is carried out to panel, when after panel one side milled, with this face for benchmark, adjust the another side of face mill panel;
(6). post-processed: red lead powder is coated with to panel contact surface, carries out hand scraping, meet the required precision of guide rail contacting surface.
The present invention adopts scraping fixture in the machine upkeep designed by technique scheme, because upper body is connected by eccentric shaft with lower body, eccentric handwheel is established in one end of eccentric shaft, the other end establishes fastening pinch wheels, upper body is established at least one shop bolt, establishes positioning strip in upper body, panel is fixed under the effect of shop bolt and positioning strip, meanwhile, by rotating eccentric handwheel pinch wheels when the height of panel reaches requirement, eccentric shaft being fixed, now can carrying out grinding to panel.The present invention, compared with the method for traditional grinding panel, has the working time short, the low and advantage that efficiency is high of labour intensity.

Detailed description of the invention
Below in conjunction with accompanying drawing, the structure of scraping fixture in machine upkeep of the present invention is illustrated.
See Fig. 1, Fig. 2, in the maintenance of lathe kind equipment, existing for CA6140 lathe, at the binding site of big palette 3 and middle supporting plate 1, in order to make swallow-tail guide rail pair combine closely, eliminating gap, between two guide rails, having one strength member-panel 2, panel 2 is designed to the shape being with gradient, effectively can eliminate the gap between guide rail after being inserted into guide rail mating surface, but scraping must be carried out, to ensure contact precision to the mating surface of panel and dovetail guide.When slightly scraping, because scraping amount is larger, very time-consuming.
See Fig. 3, Fig. 4, Fig. 5, in machine upkeep of the present invention, the structure of scraping fixture comprises upper body 5 and lower body 6, and the upper surface of upper body 5 establishes dovetail guide.Upper body 5 is connected by eccentric shaft 12 with same one end of lower body 6, eccentric handwheel 4 is established in one end of eccentric shaft 12, the other end establishes fastening pinch wheels 9, pinch wheels 9 makes it rotate for fixed eccentric shaft 12, between eccentric handwheel 4 and upper body 5 and between pinch wheels 9 and upper body 5, establish support chip 10 respectively.This end of upper body 5 is established at least one shop bolt 11, and shop bolt 11 is for positioning one end of panel 2.The other end in upper body 5 establishes positioning strip 7 along upper body 5, and positioning strip 7, for positioning the other end of panel 2, positioning strip 7 is established multiple locating hole 8 so that can the position of dynamic conditioning positioning strip 7, made panel 2 fixation.
In machine upkeep of the present invention, the using method of scraping fixture is:
(1). survey gap: insert in the guideway of lathe dovetail guide by the panel 2 of outsourcing, measure the large end of panel 2 or the gap of small end with clearance gauge, be recorded as M1.Now to hold greatly, recording gap is 0.5mm;
(2). panel is located: take out panel 2, lain against in the A face of panel 2 on the frock face, upper body of fixture, and panel 2 ends contact shop bolt 11, with location, prevents panel 2 from moving;
(3). clamping panel: by the multiple locating holes 8 on positioning strip 7, regulate positioning strip 7, make positioning strip 7 withstand panel 2, side then holds out against the side of panel 2 with screw;
(4). measure, regulate: fixture entirety is placed on guideway of grinding machine, levelling with dial gauge, then, dial gauge is moved to the large end of measuring junction of panel 2, eccentric adjustment handwheel 4 gently, drives eccentric shaft 12 to rotate, and one end height of fixture is risen, reach M1 according to dial gauge reading and require rear i.e. 0.5mm, screw down clips bearing up pulley 9;
(5). grinding panel: grinding is carried out to panel 2, when after the milled of panel B face, with this face for benchmark, adjust the A face of face mill panel, part excess stock can be removed fast like this;
(6). post-processed: red lead powder is coated with to panel 2 contact surface, carries out hand scraping, meet the required precision of guide rail contacting surface.
The present invention is through manufacturing experimently measuring and calculating on probation, and the average scraping time of past to panel is 2 days, and after utilizing this fixture, time decreased is 4 hours, and labour intensity obviously reduces, and achieves good economic benefit.
