Abstract

The utility model mainly relates to an auxiliary moving device for parts capable of moving along guide rails on machine tools, and discloses a dragging device for movable components on guide rails of machine tools, which comprises a sliding base, a drawbar and at least two clamping devices. The sliding base is arranged on a lathe bed, the drawbar support is fixedly connected onto the sliding base, the drawbar is penetratingly disposed on the drawbar support, a drawbar buffering device is arranged at one end, which contacts with the drawbar support, of the drawbar, a drawbar fixing device is arranged on the drawbar support above the drawbar, and the clamping devices are disposed on a movable component and are clamped in at least two grooves disposed at the other end of the drawbar. By the aid of the dragging device, an integral dragging process is more stable, prestressing force of ball studs can be adjusted by means of rotating first set screws, and accordingly higher dragging force is produced. When an operator forgets to release a pressure plate of a tailstock, the ball studs can be automatically pulled out from the grooves of the drawbar, so that parts cannot be damaged, and a safety protection effect is realized.

Description

Movable part pulls device on the machine tool guideway
Technical field
The utility model is chiefly directed on the guide rail of lathe upper edge the movably auxiliary moving device of parts.
Background technology
Lathe during axial workpiece, for improving machining accuracy, tends to select for use annexes such as centre frame, support roller device in the processing part, and tailstock also is the requisite parts of working shaft-like part.These annexes will move to position suitable on the lathe bed in first being processed, and in process, need not move.At present, lathe manufacturing firm tends to increase cost so undoubtedly to the independent drive unit of these attachment design; Perhaps simply use the crane of producer to come auxiliary moving, increased processing non-cutting time greatly by lathe.
Summary of the invention
The purpose of the utility model is to avoid the deficiency of prior art to provide a kind of to pull easily, and movable part pulls device on the machine tool guideway simple in structure.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: on a kind of machine tool guideway movable part pull device, be included in the saddle that lathe bed is provided with, pull bar; On described saddle, be fixed with drag link bearing; Described pull bar is located on the described drag link bearing, being provided with the pull bar buffer unit with contacted pull bar one end of drag link bearing, on the drag link bearing above the pull bar, is provided with the pull bar fixture; Also include at least two clamping devices that on described moving-member, are provided with, clamping device is clamped in two grooves of the said pull bar other end at least.
Further, described pull bar buffer unit comprises first spring, and described first spring is fixed on the described pull bar through first screw and packing ring.
Further, described first spring is a butterfly spring.
Further; Described clamping device comprises ball stud; Described ball stud front end is plugged in the groove on the said pull bar; The ball stud rear end is arranged in the thread bush, in the thread bush of the rear end of ball stud, is provided with second spring, and described second spring is fixed in the thread bush through first holding screw.
Further, described clamping device is provided with two relatively, and the ball stud of described two clamping devices is plugged in respectively in the groove of said pull bar one end.
Further, described second spring is the dual spring structure that is fitted together of spring housing of footpath size in two groups of differences.The spring acting in conjunction of footpath size can strengthen pretightning force like this in the rear end of ball stud in two groups of differences, makes connection more reliable, can obtain the bigger power that pulls.
Further, described clamping device is connected on the described moving-member through fixed block.
Further, described drag link bearing is connected on the said saddle through second screw.
Further, described pull bar fixture is second holding screw, and second holding screw is arranged on the drag link bearing through nut.
The beneficial effect of the utility model is:
1. the dish spring plays the effect of buffering, makes that whole to pull process more steady;
2. adopt the form of two groups of spring suits in the thread bush, the pretightning force that can regulate ball stud through knob first holding screw, and then obtain the bigger power that pulls;
3. first holding screw plays the effect of spline, guarantees that pull bar can not rotate;
4. when the operator forgot the pressing plate that unclamps tailstock, ball stud can be extracted in the groove of pull bar automatically, is unlikely to damage parts, plays the effect of safeguard protection.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model;
Fig. 2 is the plan structure sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Embodiment 1: shown in Figure 2 like Fig. 1, movable part pulls device on a kind of machine tool guideway; Be included in the saddle 1 that lathe bed is provided with; Pull bar 5 is fixed with drag link bearing 2 on described saddle 1, described pull bar 5 is located on the described drag link bearing 2; Being provided with the pull bar buffer unit, on the drag link bearing above the pull bar 52, be provided with the pull bar fixture with drag link bearing 2 contacted pull bar 5 one ends; Also include the described clamping device that on described moving-member, is provided with and be provided with two relatively, and the ball stud of described two clamping devices is plugged in respectively in the groove of said pull bar one end.Described pull bar buffer unit comprises first spring 8, and described first spring 8 is fixed on the described pull bar 5 through first screw 6 and first packing ring 7, second packing ring 9.Described first spring 8 is a butterfly spring.Described clamping device comprises ball stud 14; Described ball stud 14 front ends are plugged in the groove on the said pull bar 5; Ball stud 14 rear ends are arranged in the thread bush 15; In the thread bush 15 of the rear end of ball stud 14, be provided with second spring, described second spring is the dual spring structure, is made up of spring 19 and spring 17.Described second spring is fixed in the thread bush 15 through first holding screw 18.Described clamping device is connected on the described moving-member 11 through fixed block 12.Described drag link bearing 2 is connected on the said saddle 1 through second screw 10.Described pull bar fixture is that second holding screw, 3, the second holding screws 3 are arranged on the drag link bearing through nut 4.
Below be to use the utility model to drag the specific embodiment of the tailstock of horizontal lathe:
Horizontal lathe saddle 1 is provided with independently drive source, can vertically move along bed ways, can accurately be positioned the optional position on the lathe bed.When tailstock 11 needs to move; Saddle 1 drives the pull bar 5 that is fixed on the bearing 2 and moves to tailstock 11 directions; Because tailstock 11 is fixed on the lathe bed through pressing plate; The pretightning force deficiency of spring 17, spring 19 is so that tailstock is moved, and this moment, two ball studs inserted in the groove of pull bar 5 (pretightning force of ball stud 14 can be regulated through holding screw 18).Unclamp the bridge screw of tailstock 11 then; The pretightning force of spring 17, spring 19 is greater than the frictional force of tailstock, and saddle 1 drags tailstock 11 and moves to the position that processing needs under the effect of drive source, last clam member; Continue then to move saddle, pull bar 5 is extracted between two ball studs 14.Be inserted in the process of extracting whole, disk spring has played and has relaxed the effect of impacting, and holding screw 3 has played the effect of location, guarantees that pull bar 5 can not rotate, and ball stud 14 can well be inserted in the groove of pull bar 5.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
