Abstract
The invention mainly relates to an auxiliary moving device for parts movable along a guide rail on a machine tool. A dragging device for a movable component on a machine tool guide rail comprises a sliding base and a pull rod which are arranged on the bed of the machine tool, wherein a pull rod support is fixedly connected to the sliding base; the pull rod penetrates through the pull rod support; a pull rod buffering device is arranged on one end of the pull rod which contacts with the pull rod support; and a pull rod fixing device is arranged on the pull rod support above the pull rod. The dragging device further comprises at least two clamping devices arranged on the movable component, wherein the clamping devices are clamped in at least two grooves formed on the other end of the pull rod. With the dragging device, the whole dragging process is more stable; the pre-tightening force of a ball pin can be adjusted by turning a first fastening screw, thus obtaining greater dragger force; and when an operator forgets to loosen the pressing plate of a tail base, the ball pin can be automatically drawn out of the grooves of the pull rod without damaging the parts; therefore, the safety protection function is realized.
Description
Technical field
The present invention is chiefly directed on the guide rail of lathe upper edge the movably auxiliary moving device of parts.
Background technology
Lathe for improving machining accuracy, tends to select for use annexes such as centre frame, support roller device when the axial workpiece of processing part, 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 not need to move in process.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 objective of the invention is to avoid the deficiencies in the prior art to provide a kind of and pull easily, moving-member pulls device on the machine tool guideway simple in structure.
For achieving the above object, the technical scheme that the present invention takes is: moving-member pulls device on a kind of machine tool guideway, 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, is provided with the pull bar fixture on the drag link bearing above the pull bar; Also include at least two clamping devices that are provided with on described moving-member, clamping device is clamped in two grooves of the described 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 by 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 described pull bar, the ball stud rear end is arranged in the thread bush, be provided with second spring in the thread bush of the rear end of ball stud, described second spring is fixed in the thread bush by 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 described 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 by fixed block.
Further, described drag link bearing is connected on the described saddle by second screw.
Further, described pull bar fixture is second holding screw, and second holding screw is arranged on the drag link bearing by nut.
The invention has the beneficial effects as follows:
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 by 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 a main TV structure schematic diagram of the present invention;
Fig. 2 is a plan structure schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
Embodiment 1: as Fig. 1, shown in Figure 2, moving-member 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 described 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 by 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 described 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 by first holding screw 18.Described clamping device is connected on the described moving-member 11 by fixed block 12.Described drag link bearing 2 is connected on the described saddle 1 by 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 by nut 4.
Below be to use the present invention 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 are mobile, 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 by 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 by 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 mobile saddle then, 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 only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
