Abstract
The utility model relates to positioning devices for a heavy horizontal lathe central frame and a lathe body. A positioning device for a machine tool central frame is mainly characterized in that a step-shaped fixing pressing plate is placed below a central frame body and is fixed through a fixing pressing plate bolt, a step plane of the step-shaped fixing pressing plate is attached to a lower guiding rail plane of a machine tool guiding rail, and a trapezoid panel for positioning is formed between the central frame body and an inner guiding rail plane of the machine tool guiding rail and is fixedly connected with the central frame body through panel T-shaped bolts. The positioning device for the machine tool central frame has the advantages that on the central frame body, an original rectangular panel positioning form is changed into a trapezoid panel positioning form, complex processes that according to the rectangular panel positioning form, six nuts are loosened firstly, then the panel is rotated, thirdly locking bolts are loosened and lastly the panel can move are well solved, labor intensity of workers is reduced, auxiliary time is shortened, production efficiency is improved, cost is reduced, and the cost performance of a machine tool is improved.
Description
Technical field
The utility model relates to the device of heavy horizontal lathe centre frame and lathe bed location.
Background technology
At present, on heavy horizontal lathe, often need the position of follow rest.Because the fixed form of centre frame great majority adopt rectangle panel form to carry out, so when needing the position of follow rest, at first need unclamp six locking nuts and the four block pressur plates bolting nut at centre frame panel two ends, rotate the panel clamping screw then and unclamp panel, ability follow rest (seeing Fig. 2, Fig. 3), this structure has not only increased the non-cutting time of lathe, and has increased working strength of workers, thereby influences labor productivity.In order to reduce cost, improve the cost performance of lathe, we have designed this heavy horizontal lathe centre frame positioner.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of lathe centre frame positioner is provided.To solve the position of follow rest fast and accurately, reduce working strength of workers, shorten non-cutting time, improve labor productivity, reduce cost.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of lathe centre frame positioner, its main feature are to be provided with the stairstepping fixation clip below the support body of center, by the fixation clip bolting; The lower guideway face of the cascaded surface of stairstepping fixation clip and machine tool guideway is fitted; Be provided with the trapezoidal panel in location between the interior guide pass of center support body and machine tool guideway, the location is connected with tommyhead bolt by panel with trapezoidal panel and center support body.
Described lathe centre frame positioner, close with the inclined-plane and the centre frame consideration of trapezoidal panel described location.
The beneficial effects of the utility model are:
On the support body of center, change trapezoidal panel positioning form into by original rectangle panel positioning form, rectangle panel positioning form need unclamp six nuts earlier, rotation panel clamping screw unclamps the complicated procedure that panel could move thereby solve well, reduced working strength of workers, shorten non-cutting time, enhance productivity, reduced cost, improved the cost performance of lathe.Centre frame is being positioned, when unclamping, can utilize the centre frame positioner to realize the centre frame location and unclamp easily.The utility model centre frame positioner is easy to use, reliable.
Description of drawings:
Fig. 1 looks schematic diagram for the utility model lathe centre frame positioner master.
Fig. 2 is former centre frame positioner schematic diagram.
Fig. 3 is the D-D cross-sectional schematic of Fig. 2.
Among the figure: 1, fixation clip; 2, fixation clip bolt; 3, center support body; 4, the trapezoidal panel in location; 5, panel tommyhead bolt; 6, panel locking nut; 7. machine tool guideway; A, pressing plate binding face; B, panel binding face.
The specific embodiment
Below principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Embodiment 1: see Fig. 1, a kind of lathe centre frame positioner is provided with stairstepping fixation clip 1, by the fixation clip bolting below center support body 3; The lower guideway face of the cascaded surface of stairstepping fixation clip 1 and machine tool guideway 7 is fitted; Be provided with between the interior guide pass of center support body 3 and machine tool guideway 7 guide rails and locate with trapezoidal panel 4, the location is connected with tommyhead bolt 5 by panel with center support body 3 with trapezoidal panel 4.
Fit with the inclined-plane and the center support body 3 of trapezoidal panel 4 in described location.
Shown in Fig. 1, we as can be seen, center support body 3 is installed on the bed piece, guarantee that by the assembling scraping A face of fixation clip 1 is not gone into lathe bed lower guideway face 0.04mm clearance gauge and the pressing plate usefulness nut 2 that is locked, assembling the facing-up location does not then go into the B face and the center support body 3 contact-making surface 0.04mm clearance gauges of trapezoidal panel 4, the back is by panel tommyhead bolt 5 well in facing-up, and panel locking nut 6 locatees center support body 3, be locked on the lathe bed.When needing the position of follow rest, only need unclamp panel locking nut 6, by the location with the deadweight of trapezoidal panel 4 to bottom offset, need not to unclamp panel by rotating the panel clamping screw again.In former centre frame, centre frame is fixed on centre frame on the bed piece by quadruplet fixation clip 1, panel only plays the effect of location and guiding, and in the centre frame positioner, the location is location, guiding and locking with the effect of trapezoidal panel 4, and 1 of quadruplet fixation clip plays auxiliary locking, the assurance centre frame can not be turned on one's side when mobile, when the needs follow rest, no longer unclamp quadruplet fixation clip 1, only need unclamp two panel locking nuts 6 and get final product.This centre frame positioner solves six locking nuts and four block pressur plates that the rectangle panel need unclamp centre frame panel two ends earlier well and unclamps the complicated procedure that panel could move with bolting nut, rotation panel clamping screw, reduced working strength of workers, shorten to have assisted and help the time, improved production efficiency, reduce cost, improved the cost performance of lathe.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
