Description
Technical field
The present invention relates to guide rail mounting technique field, and in particular to a kind of calibration structure of high-precision guide rail linearity and its
Method.
Background technology
Nowadays the advanced precision measurement equipment of multiple types is automobile, aviation, national defence, engineering, mould, electronics, information technology, doctor
The industries such as treatment provide substantial amounts of facility, promote the development of industry-by-industry.
Chinese invention patent 200810243297.9 discloses a kind of guide rail straightness regulating device, and it includes can be to leading
Rail or beam apply the cam or eccentric wheel governor motion of the controllable extruding force of stepless continuous, and consolidating for secured adjusted mechanism
Determine device.Governor motion include cam, sliding block, sliding block moving guide rail and to by sliding block in cam slide moving guide rail
Fixed holding screw, cam can be arranged on cam slide around the movable of its core wheel rotation, and sliding block can be moved in sliding block and led
Moved in rail.It is provided with cam and is easy to instrument to put forth effort to put forth effort portion to rotate the cooperation of cam.
Chinese invention patent 200420013964.1 discloses a kind of level meter regulator, and it includes chassis, adjustment seat, its
It is characterised by：Adjustment seat is connected to a rotating disk by pivoted housing, and rotating disk can rotate around adjustment seat, have set screw on the pin of adjustment seat,
There is hiding card pin the both sides of adjustment seat, and card pin is connected by spring with button, press lower button, and card pin stretches out, and can be caught in metope etc.
Place, release button, card pin are hidden in adjustment seat under the action of the spring.
Although above-mentioned adjuster respectively has feature, some defects be present, overall equipment degree of regulation is relatively low, it is difficult to suitable
The occasion that accuracy requirement is high is answered, using mechanisms such as general lever, sliding blocks, application condition itself is big, and adjustment control means
It is single, adjustable position, meet that the direction of work requirements is less, and also adaptability is poor, and device structure is big compared with complex maintenance amount
Etc..In addition, the method for regulation guide rail linearity is usually to lean on one face of machine tooling now, then the reference plane of guide rail is top
Go, hold out against guide rail from side with screw, such mounting means just thinks that guide rail is straight, and this method is entirely by machine in fact
The machining accuracy of bed ensures the installation accuracy of guide rail, if machining accuracy reaches requirement, is that can not install high-precision lead
Rail.Here it is the drawbacks of it, and this installation method full accuracy may be exactly 0.01mm.
The content of the invention
An object of the present invention is：In view of the shortcomings of the prior art, a kind of high-precision guide rail linearity is provided
Calibration structure, the calibration structure require no so high to the face of keeping to the side of workpieces processing, and the linearity of guide rail can use tables of data
Show to come, the linearity of guide rail can be adjusted in the range of 0.002mm, suitable for the high lathe of required precision；Furthermore it is also possible to
The loosening of guide rail is prevented, to there is the guide rail anti-loosing effect in vibrations especially good.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of calibration structure of high-precision guide rail linearity, including base, marble parallel rule, guide rail, sliding block, voussoir, hold out against
Block, set screw and fixed screw, the marble parallel rule are installed on the side of the base, and the base is provided with installation
Groove and the regulating tank being connected with the mounting groove, the guide rail is lock onto in the mounting groove by the fixed screw, described
Guide rail is close to the side wall of the mounting groove, and the sliding block is slideably positioned in the guide rail, and the placed on top of the sliding block is useful
In the amesdial of calibration guide rail linearity, the voussoir and the withstanding tight block are mounted in the regulating tank, the withstanding tight block
End face be resisted against the guide rail, the other end of the withstanding tight block is resisted against the end face of the voussoir, and the voussoir is another
End face is close to the side wall of the regulating tank.The linearity of guide rail is adjusted by above-mentioned calibration structure, the structure pair
The face of keeping to the side of workpieces processing requires no so high, and the linearity of guide rail can be showed with data, can adjust guide rail
Linearity is in the range of 0.002mm, suitable for the high lathe of required precision；In addition, said structure is also prevented from the pine of guide rail
It is dynamic, to there is the guide rail anti-loosing effect in vibrations especially good.
The a kind of of calibration structure as high-precision guide rail linearity of the present invention improves, and the voussoir has first
Inclined-plane, the withstanding tight block have the second inclined-plane, first inclined-plane and second inclined-plane matching.
The a kind of of calibration structure as high-precision guide rail linearity of the present invention improves, the withstanding tight block with it is described
Gap be present between the side wall of regulating tank.
The a kind of of calibration structure as high-precision guide rail linearity of the present invention improves, the voussoir and the top
The quantity of tight block is multiple, and each voussoir matches a withstanding tight block.
It is another object of the present invention to provide a kind of calibration method of high-precision guide rail linearity, including following step
Suddenly：
1）Marble parallel rule is arranged on to the sidepiece of base, causes marble parallel rule to be in parastate with guide rail as far as possible,
Amesdial is laid on the sliding block being slidably connected with guide rail so that the measurement head of amesdial and the side wall of marble parallel rule connect
Touch, now measure the reading of marble parallel rule one end A points, then mobile sliding block is motionless in amesdial position to the other end
The value of marble parallel rule the other end B points is measured, if the reading of A with B points is consistent, illustrates marmorean linearity school
Standard, if the reading of A and B points is inconsistent, illustrate that marmorean linearity is not calibrated, need glue hammer gently to beat marble parallel rule
Side so that the reading of A with B points reaches consistent；
2）After calibrating marble parallel rule, marble parallel rule is locked, then moving guide rail, in mobile process
The reading of each point, if each point is consistent with A or B point readings between A and B points, illustrates the linearity of guide rail between middle observation A and B points
It is calibrated, if each point and A or B point readings are inconsistent between A and B points, need to enter the position of inconsistent each point corresponding rails
Row adjustment, such as：Risen or fallen by the tightness withstanding tight block for adjusting set screw, now withstanding tight block applies to guide rail
Power can diminish or become big so that inconsistent each point is consistent with the reading of A or B points, finally reach the straight of calibration guide rail
Dimension.
Adjustment to guide rail linearity can rapidly be realized by the above method, change conventional method to guide rail straight line
The adjustment of degree, improve lathe service precision.
