Abstract
The utility model relates to a tailstock of the ordinary horizontal machine tool, in particular to a machine tool tailstock apparatus with an unloading device. The utility model is characterized in that four sets of unloading devices respectively composed of holding screws, a pressing block, a disk spring, a backing block, a rolling wheel and a cylindrical pin are arranged in a tailstock body and a slide board. The backing block is arranged in the inner cavity of the slide board; the disk spring and the pressing block are arranged on the backing block; the rolling wheel is supported on the slide board by the cylindrical pin and is able to roll on the machine tool body. The sliding friction between the tailstock and the machine tool body is improved to the rolling friction of the rolling wheel, which thoroughly solves the defect of the laborious and difficult pulling when moving because of the heavy weight of the tailstock. When the tailstock is needed to be moved, the clamping screws are loosened, and then the tailstock can be moved conveniently with labor saving, easily and rapidly.
Description
Technical field
The utility model relates to a kind of tailstock unloading mechanism of general horizontal lathe parts, particularly a kind of general horizontal lathe.
Background technology
At present, the tailstock of general general horizontal lathe directly acts on the lathe bed by slide plate, matches by dovetail between tailstock and lathe bed, and the relative motion between tailstock and lathe bed is sliding friction, and its frictional force is very big.Because tailstock moving generally on lathe bed all come direct push-and-pull by manpower, the weight of tailstock is heavier again, so manpower is required great effort when the push-and-pull tailstock very much.
Summary of the invention
Technical problem to be solved in the utility model is, overcome the deficiency that the resistance of motion that causes owing to sliding friction when tailstock moves in the prior art is big, require great effort, a kind of lathe tailstock device that has relief arrangement is provided, it can make the motion mode of the relative motion realization rolling friction between tailstock and lathe bed, and resistance was little, laborsaving when tailstock was moved.
Technical solution of the present utility model is, be provided with tailstock body, the downside of tailstock body is provided with slide plate and can makes the lower platen of tailstock body clamping and positioning on lathe bed, slide plate and tailstock body are fixedly connected, slide plate has the dovetail groove that matches with the lathe bed dovetail, it is characterized in that: be provided with relief arrangement in slide plate and the tailstock body, its relief arrangement is made of holding screw, briquetting, disk spring, back-up block, roller and straight pin.
Back-up block is located in the inner chamber of slide plate and slide plate slides relatively, and disk spring and briquetting are located at the upside of back-up block, and roller is located at the downside of back-up block and is supported on the slide plate by straight pin, and roller can roll on lathe bed.
The utility model has the advantages that, thoroughly solved because tailstock Heavy Weight, the difficult deficiency of drawing of effort when mobile are improved to rolling friction with the sliding friction between tailstock and lathe bed.And dependable performance, simple in structure, the tailstock conveniently moving is laborsaving, easily quick.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Number in the figure: tailstock 1, slide plate 2, lower platen 3, tommyhead bolt 4, packing ring 5, high nut 6, interior hexagonal awl end holding screw 7, briquetting 8, disk spring 9, back-up block 10, roller 11, straight pin 12, lathe bed 13.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
The utility model embodiment is provided with tailstock body 1, and the downside of tailstock body 1 is provided with slide plate 2 and lower platen 3, and slide plate 2 is fixedly connected with tailstock body 1 and is one, and slide plate 2 matches by dovetail groove and dovetail with lathe bed 13.Lower platen 3 makes tailstock body 1 clamping and positioning on lathe bed 13 by bolt 4, packing ring 5, high nut 6.Be provided with four groups of relief arrangements in slide plate 2 and the tailstock body 1, its each group relief arrangement is made up of interior hexagonal awl end holding screw 7, briquetting 8, disk spring 9, back-up block 10, roller 11 and straight pin 12 respectively.Back-up block 10 is located in the inner chamber of slide plate 2 and slide plate 2 slips relatively, and disk spring 9 and briquetting 8 are located at the upside of back-up block 10, and roller 11 is located at the downside of back-up block 10 and is supported on the slide plate 2 by straight pin 12, and roller 11 can roll on lathe bed 13.Four groups of relief arrangements are located at four edges of tailstock body 1 respectively.
The utility model has thoroughly solved because tailstock Heavy Weight, the difficult deficiency of drawing of effort when mobile, and the sliding friction during with tailstock 1 and 13 relative motions of lathe bed is improved to rolling friction.When needs movable tail frame body 1, unclamp high nut 6 earlier, under the spring force effect of four groups of disk springs 9, tailstock body 1 and slide plate 2 float from lathe bed 13, make whole tailstock body 1 only have four rolling 11 to contact with lathe bed 13, push-and-pull tailstock body 1, roller 11 promptly roll on lathe bed 13.When tailstock 1 moves to desired location, tighten high nut 6, the tommyhead bolt 4 of slinging clamps lower platen 3, makes whole tailstock 1 and lathe bed 13 positioning and fixing.
The operation principle of unloading mechanism: hexagonal awl end holding screw 7 in the rotation, by briquetting 8 pressure is passed to disk spring 9, back-up block 10, roller 11, lathe bed 13, when disk spring 9 is urged to when a certain amount of, spring tension reacts on briquetting 8, lift slide plate 2 slightly by briquetting 8, screw 7, making between slide plate 2 and the lathe bed 13 has little clearance, only has four rolling 11 to contact with lathe bed 13, push-and-pull tailstock body 1, roller 11 just can roll on lathe bed 13.When moving to desired location, position tailstock body 1 and lathe bed 13 fixing by tommyhead bolt 4 again.
