Abstract

The invention relates to an adjustable dovetail tenon and groove guide rail structure which comprises a base and a sliding table. A dovetail tenon is arranged on the base. The adjustable dovetail tenon and groove guide rail structure is characterized in that a groove is formed in the sliding table, a half-dovetail groove which is matched with the dovetail tenon is formed in one side of the groove, an insertion strip is arranged on the other side of the groove and is provided with an oblique plane, the oblique plane is matched with the dovetail tenon, a plurality of horizontal set screws are arranged on a side wall of the sliding table and are positioned on the outer side of the insertion strip, a plurality of perpendicular through holes are formed in the insertion strip, a plurality of perpendicular screws penetrate the perpendicular through holes to be connected with the top of the groove of the sliding table, the insertion strip is butted onto the dovetail tenon by the aid of the horizontal set screws and the perpendicular screws, and the insertion strip and the half-dovetail groove form a dovetail groove which is matched with the dovetail tenon. The adjustable dovetail tenon and groove guide rail structure has the advantages that the adjustable dovetail tenon and groove guide rail structure is simple and compact, is low in manufacturing cost and is provided with an adjustable insertion strip structure, accordingly, gaps between the dovetail tenon and the dovetail groove can be conveniently adjusted at any time, the machining precision of a machine tool can be guaranteed, the maintenance workload can be reduced, and the production efficiency can be improved.

Description

Adjustable dovetail tongue-and-groove guide rail structure
Technical field
The present invention relates to a kind of slide guide device, especially relate to a kind of adjustable dovetail tongue-and-groove guide rail structure.
Background technology
Dovetail tongue-and-groove guide frame is in a large number for lathe, machining equipment and high accuracy slide unit isoline reciprocator, for accurate guiding is made in the straight reciprocating motion of mechanism.Dovetail and dovetail groove, in long-term use procedure, very easily cause wearing and tearing, make to produce gap between dovetail and dovetail groove, thereby the precision of lathe, machining equipment is reduced; And, due to the processing technology complexity of dovetail and dovetail groove, requirement on machining accuracy is higher, production cost is high, and common way is that wear-resisting panel is set between dovetail and dovetail groove, can after wear-resisting panel wearing and tearing, change, but change wear-resisting panel and need to carry out dismounting to equipment, the workload of safeguarding is large, for the especially difficulty of maintenance of the dovetail tongue-and-groove guide rail of heavy duty machine tools, can affect to a certain extent production efficiency.
Summary of the invention
The applicant, for above-mentioned problem, is studied improvement, and a kind of adjustable dovetail tongue-and-groove guide rail structure is provided, simple and compact for structure, low cost of manufacture, can adjust the gap between dovetail and dovetail groove easily, guarantee the machining accuracy of lathe, reduce maintenance workload, enhance productivity.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of adjustable dovetail tongue-and-groove guide rail structure, comprise pedestal and slide unit, described pedestal is provided with dovetail, described slide unit is provided with groove, one side of described groove is half dovetail groove matching with described dovetail, the opposite side of described groove is provided with panel, described panel is provided with the inclined-plane coordinating with described dovetail, the sidewall of the described slide unit in described panel outside is provided with multiple levels to holding screw, described panel is provided with multiple vertical vertical through hole, multiple groove end faces that vertically connect described slide unit to screw through described vertical vertical through hole, described level is to holding screw and describedly vertically to screw, described panel is against on described dovetail, described panel forms with described half dovetail groove the dovetail groove matching with described dovetail.
Further:
Described vertical vertical through hole is mounting hole.
Technique effect of the present invention is:
One disclosed by the invention is adjustable dovetail tongue-and-groove guide rail structure, simple and compact for structure, low cost of manufacture, adopt adjustable panel structure, can adjust at any time and easily the gap between dovetail and dovetail groove, guarantee the machining accuracy of lathe, reduce maintenance workload, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the present invention includes pedestal 1 and slide unit 2, pedestal 1 is provided with dovetail 3, slide unit 2 is provided with groove, one side of groove is half dovetail groove matching with dovetail 3, the opposite side of groove is provided with panel 4, panel 4 is provided with the inclined-plane coordinating with dovetail 3, the sidewall of the slide unit 2 in panel 4 outsides is provided with multiple levels to holding screw 5, panel 4 is provided with multiple vertical vertical through hole 7, the vertical through hole 7 that hangs down is mounting hole, multiple groove end faces that vertically connect slide unit 2 to screw 6 through the vertical through hole 7 that hangs down, multiple levels are to holding screw 5 and vertically to screw 6 along being uniformly distributed on panel 4 length directions, level is to holding screw 5 and vertically can determine according to the actual requirements to the quantity of screw 6, level is to holding screw 5 and vertically to screw 6, panel 4 is against on dovetail 3, panel 4 forms with half dovetail groove the dovetail groove matching with dovetail 3, slide unit 2 can do reciprocating linear motion along the dovetail 3 on pedestal 1 like this.Because vertical vertical through hole 7 is mounting hole; simultaneously; the even gap 8 of leaving between the end face of panel 4 and slide unit 2 grooves and sidewall; by level to holding screw 5 and vertically regulate the gap between slide unit 2 and dovetail 3 to screw 6 from both direction; guarantee the kinematic accuracy of slide unit 2, thereby guarantee the machining accuracy of lathe.Owing to can carrying out the adjustment in gap in stopped status, row dismounting when to equipment, has saved the time of safeguarding widely; reduce maintenance workload, enhance productivity, and can monitor the gap between slide unit 2 and dovetail 3 at any time; adjust at any time, guarantee the machining accuracy of lathe.
