Abstract
A pre-stressing structure of a lead screw bearing which is convenient to use comprises a supporting base. The supporting base is provided with a transverse lead screw which is in relatively rotating connection with the supporting base through a bearing. The right part of the supporting base is connected with a supporting cover through an anti-loose screw. The left end of the supporting cover is in threaded connection with a nut-type pressing block. An adjusting pad is arranged between the bearing and the nut-type pressing block. The left end of the lead screw is in threaded connection with a round nut.
Description
Technical field
The utility model relates to a kind of lathe, relates in particular to a kind of leading screw bearing pre-pressing structure.
Background technology
General leading screw bearing pre-pressing structure adopts the seam of casing or supporting base to give the location, outer ring of bearing more, adjust the thickness of the adjusting pad between bearing then, the mode pretension that screws with round nut again, this structure need repeatedly dismounting when adjusting the thickness of adjusting pad, use trouble.
Summary of the invention
The purpose of this utility model provides a kind of leading screw bearing pre-pressing structure easy to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of leading screw bearing pre-pressing structure, comprise supporting seat, it is characterized in that: horizontal leading screw is installed on the supporting seat, leading screw is rotatably connected by bearing is relative with supporting seat, and the right part of supporting seat connects supporting cover by backing-up screw, the right-hand member of the supporting cover nut type briquetting that has been threaded, design has adjusting pad, the leading screw left end round nut that has been threaded between bearing and the nut type briquetting.
The utility model has the advantages of and be: owing on the utility model supporting seat horizontal leading screw is installed, leading screw is rotatably connected by bearing is relative with supporting seat, the right part of supporting seat connects supporting cover by backing-up screw, the right-hand member of the supporting cover nut type briquetting that has been threaded, design has adjusting pad between bearing and the nut type briquetting, the leading screw left end round nut that has been threaded, use the utility model disposable adjusting pad to be polished, adjust the nut type gland of right-hand member then, screw the round nut of left end, the leading screw pretension is got final product, so use the utility model convenient and swift.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing: 1, round nut; 2, bearing; 3, adjusting pad; 4, backing-up screw; 5, supporting seat; 6, nut type briquetting; 7, leading screw; 8, supporting cover.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of leading screw bearing pre-pressing structure, comprise supporting seat 5, horizontal leading screw 7 is installed on the supporting seat 5, leading screw 7 and supporting seat 5 are by bearing 2 relative being rotatably connected, and the right part of supporting seat 5 connects supporting covers 8 by backing-up screw 4, the right-hand member of the supporting cover 8 nut type briquetting 6 that has been threaded, design has adjusting pad 3, the leading screw 7 left ends round nut 1 that has been threaded between bearing 2 and the nut type briquetting 6.
In the present embodiment, be connected by backing-up screw 4 between supporting cover 8 and the nut type briquetting 6.
Operation principle of the present utility model is: behind the plain grinding adjusting pad, leading screw, adjusting pad, bearing and round nut are packed in the supporting base in the lump, rotation nut type gland, after making it to arrive suitable position, screw the purpose that round nut can reach preloaded bearing, screw backing-up screw 1 fixing getting final product afterwards again.
