Abstract
The invention relates to an adjusting device for a guideway clearance. The defect that a guideway clearance between oil film supports cannot be adjusted through an existing mode for adjusting the clearance by using a pressing plate or an inlaying strip is overcome. The adjusting device for the guideway clearance comprises guide rails and bearings, wherein the guide rails are vertically fixed to a punch press, and the bearings are matched with the guide rails and used for supporting sliding blocks. An eccentric shaft is arranged in an inner ring of each bearing in a penetrating mode. Each eccentric shaft is provided with an eccentric part. The axis of the inner ring of each bearing and the rotating axis of the corresponding eccentric shaft are eccentrically arranged. The inner ring of each bearing and the corresponding eccentric shaft are fixed. The axis of the inner ring of each bearing is eccentric relative to the rotating axis of the corresponding eccentric shaft. In this way, when each eccentric shaft rotates, the corresponding bearing is eccentric relative to the rotating axis of the eccentric shaft, and accordingly the guideway clearance between an outer ring of each bearing and the corresponding guide rail groove can be adjusted; in addition, adjusting of the clearance is achieved when the outer ring of each bearing is close to the corresponding guide rail groove or the outer ring of each bearing is separated from the corresponding guide rail groove, and hence the requirement for adjusting the clearance between the oil film supports can be met; the clearance between the outer ring of each bearing and the corresponding guide rail groove is adjusted in an eccentric mode, so that continuous adjusting is achieved.

This invention also solves the mode that the adjustment of existing gap adopts pressing plate or panel, interrupted adjustment can only be realized, continuously adjustable defect cannot be realized, a kind of guide passage lash adjusting device is provided, use eccentric shaft adjusts the guide passage gap between bearing outer ring and guide-track groove, realizes the adjustment of guide passage Connexin.
The technical solution adopted for the present invention to solve the technical problems is: a kind of guide passage lash adjusting device, comprise the guide rail that is vertically fixed on punch press and the bearing being used for support slipper matched with guide rail, bearing inner race is equipped with eccentric shaft, eccentric shaft is provided with eccentric part, and the axis of bearing inner race and the pivot center of eccentric shaft are set for the eccentric.Bearing inner race and eccentric shaft fix, the pivot center of the axis relative eccentric axle of bearing inner race is eccentric, such eccentric rotation axis, the pivot center of bearing relative eccentric axle is eccentric, namely the guide passage gap between adjustable bearing outer ring and guide-track groove, and the adjustment of this gap be by bearing outer ring and guide-track groove near or be separated and realize, therefore can reach the gap adjustment requirement that oil film supports; Gap between centering type adjustment bearing outer ring and guide-track groove, realizes continuous setup.
As preferably, the axis of eccentric part is the pivot center of eccentric shaft.
As preferably, eccentric part is connected with slide block, and eccentric shaft opposing slider rotates around the axis of eccentric part.
As preferably, the eccentric part of eccentric shaft is in the middle part of eccentric shaft, and bearing is fixed on wherein one end of eccentric shaft, and this end is coaxial with the other end of eccentric shaft.
As preferably, the rotation of eccentric shaft is damping rotary.Eccentric shaft is damping rotary, makes eccentric shaft have the function of anti-rotation, namely needs external force to realize eccentric shaft turns, and anti-limited slip block moves up and down eccentric shaft rotation in process, keeps stable after guaranteeing gap adjustment.
As preferably, eccentric part is equipped with dial, dial is provided with eccentric shaft in the mode of indentation and rotates tune gap value.
As preferably, gap value is adjusted to comprise bearing inner race axis and the eccentric shaft turns axis eccentricity value in the horizontal of bearing inner race axis line track line and correspondence.
As preferably, a guide rail is at least equipped with two bearings, and two bearings is arranged up and down.
As preferably, a punch press is fixed with four guide rails, two guide rails are in a plane, and another two guide rails are in another plane, and two planes are parallel to each other and point are in both sides before and after punch press.
As preferably, adjusting device also comprises the oil film calibrator in test bearing outer ring and guide-track groove gap, and is furnished with corresponding Displaying Meter, and Displaying Meter to be fixed on slide block and corresponding with the bearing of test position, movement on oil film calibrator is synchronous with bearing.
The invention has the beneficial effects as follows: bearing inner race and eccentric shaft fix, the pivot center of the axis relative eccentric axle of bearing inner race is eccentric, such eccentric rotation axis, the pivot center of bearing relative eccentric axle is eccentric, namely the guide passage gap between adjustable bearing outer ring and guide-track groove, and the adjustment of this gap be by bearing outer ring and guide-track groove near or be separated and realize, therefore can reach the gap adjustment requirement that oil film supports; Gap between centering type adjustment bearing outer ring and guide-track groove, realizes continuous setup.
