Pin down, i.e., when guide rail protection cover operation has some setbacks, main shaft will be affected, and work piece surface has decorative pattern and formed, and influence to add
The quality of workpiece, secondly, when guide rail protection cover operation has some setbacks, crooked, stuck phenomenon occurs in protective cover.
The content of the invention
Having some setbacks for the existing machine tool guide rail protecting cover operation of solution causes workpieces processing surface decorative pattern, out-of-flatness occur, with
And protective cover is crooked, the technical problem such as stuck, the present invention provides a kind of pre-tightening apparatus of machine tool guide rail protecting cover, concrete structure bag
Include：Appearance is in cone, and bottom and top are circular pretension round platform, circular hole inner cavity are equipped with the middle part of the pretension round platform, the bottom of with
Portion penetrates through, and the first threaded hole of a small-bore is connected at top, is designed with the cone both sides symmetric position of pretension round platform
The stepped hole of perforation, the second threaded hole close to the bottom of pretension round platform for small-bore, the circular hole inner cavity with pretension round platform bottom
The pretension block of clearance fit installation, it is equipped with circular groove, close to pretension round platform bottom close to one end of pretension round platform inner cavity along excircle
The one end in face stretches out, and the spring being fixed in the pretension block circular groove, spring can freely be stretched in the inner cavity of pretension round platform
Contracting, the adjustment sheet being fixed on the free end of spring, the sunk screw being connected with the first threaded hole at the top of pretension round platform.
The technical solution has technical effect that：The two lateral surfaces installation pre-tightening apparatus of first segment protective cover, pretension block support
Firmly the second section protective cover, when any protective cover is subject to the active force for making it possible to shift, due to the acting in opposition of spring
Power, can rectify a deviation in time, ensure that each section protective cover is moved along the centre position of guide rail, and run smooth.
In order to make the connection between the pre-tightening apparatus and protective cover more stablize, difficult to slide, dislocation, to above-mentioned technical side
Pretension round platform in case has done further improvement, specifically, the bottom of pretension circle is additionally provided with round platform, the internal diameter and circle of the round platform
The internal diameter of hole inner cavity is identical.The hole for assembling this round platform, the pre-tightening apparatus and protective cover are opened up in the corresponding connecting portion of protective cover
During assembling, which is stuck in the location hole of protective cover, consolidates assembling.
Protective cover is during stretching and compression, to reduce between adjacent protective cover and pre-tightening apparatus and protective cover
Between frictional force, an end structure of the pretension block close to pretension round platform bottom is sliding block, cylindrical rolling element or sphere.
Frictional force between further reduction protective cover and between pre-tightening apparatus and protective cover, can be in pretension block
Pad is wrapped up on the round platform of pretension round platform bottom, the material of pad selects soft metal or has wear-resisting non-metallic material
Material, such as brass, aluminium, nylon, polyurethane.

Embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Attached drawing is closed, the present invention is described in further details.It should be appreciated that specific embodiment described herein is only explaining this
Invention, is not intended to limit the present invention.
It is the structure diagram of pre-tightening apparatus of the present invention as shown in Figures 1 to 4, specifically includes：Appearance is in cone, bottom
It is circular pretension round platform 1 with top, circular hole inner cavity is equipped with the middle part of the pretension round platform, penetrated through with bottom, is connected at top
Lead to the first threaded hole 11 of a small-bore, the stepped hole of perforation is designed with the cone both sides symmetric position of pretension round platform, it is close
The bottom of pretension round platform is the second threaded hole 12 of small-bore, and the bottom of pretension round platform 1 is additionally provided with round platform 6, the internal diameter of the round platform
Identical with the internal diameter of circular hole inner cavity, the pretension block 2 with the circular hole inner cavity clearance fit installation of 1 bottom of pretension round platform, it is close to pre-
One end of tight round platform inner cavity, circular groove 21 is equipped with along excircle, is stretched out close to one end of pretension round platform bottom surface, is fixed on described
Spring 3 in pretension block circular groove 21, spring 3 can freely stretch in the inner cavity of pretension round platform, be fixed on the free end of spring 3
Adjustment sheet 4, the sunk screw 5 being connected with the first threaded hole 11 at the top of pretension round platform, pretension block 2 is close to pretension round platform bottom
End face be equipped with round platform 22, be enclosed with pad 7 on round platform 22, pad as polyurethane material.
The lateral surface for often saving machine tool guide rail protecting cover is designed with multiple location holes of installation pre-tightening apparatus, by pretension of the present invention
Round platform 6 at device bottom surface is embedded in the location hole on protective cover, the location hole the second threaded hole 12 being aligned on protective cover, to
Sunk screw is installed in second threaded hole 12, pre-tightening apparatus is fixed on protective cover, screws what is be connected with the first threaded hole 11
Adjustment sheet 4 is compressed spring, spring is remained certain by sunk screw 5, sunk screw 5 to propulsion in the middle part of inner cavity, adjustment sheet 4
Elastic acting force, when guide rail protection cover during the motion, it is a certain section protective cover made suddenly be subject to by it to side passage
When firmly, then the spring in the pre-tightening apparatus of side is under pressure, and spring contraction produces the reverse elastic force of bigger, then anti-to this
Shield applies an opposition, therefore protective cover remains at intermediary movements.
