Abstract
The utility model relates to the machine class, in particular to a cutting-edge clearance regulation mechanism for plate-shearing machine, which mainly consists of an upper slide rest, a fixing seat, a fixed axis, a regulating arm and an eccentric axis; wherein, the fixing seat and the lower part of the upper slide rest are fixedly connected, and the fixed axis and the fixing seat are fixedly connected; holes are opened at the two ends of the regulating arm, the hole of one end is movably matched with the fixed axis, the hole of the other end are movably matched with the eccentric axis. The utility model has the advantages of simple structure, rigid connection and good shearing quality, and the gap does not generate changes after bearing impact load and dispenses with frequent artificial adjustment.
Description
Technical field
The utility model relates to the lathe class, relates to a kind of plate shearing machine cutting edge clearance adjustment mechanism concretely.
Background technology
What the cutting edge clearance adjustment mechanism of lock formula plate shearing machine adopted usually at present is pre-compressed spring formula or rolling wheel guide rails structure, the two principle is identical, as shown in Figure 1 be a kind of three-point rolling wheel guide rail mechanism, precompressed guide rail (5) is attached on upper rail (3) and the lower guideway (1) knife rest (4) all the time and does the reciprocating action of no gap before in this mechanism, guide roller (2) be connected to flexible connecting structure, when shearing different plate, in rotation hand wheel (6) adjusting, cutting edge gap between the bottom knife, the shortcoming of this class formation is, complicated integral structure, because this structure need be born bigger shock loading when shearing steel plate, flexible connecting structure is hit after the power for a long time, the cutting edge gap can change, and need frequent artificial the adjustment, thereby quality is sheared in influence.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, and a kind of plate shearing machine cutting edge clearance adjustment mechanism is provided, the be rigidly connected structure of this mechanism by using eccentric shaft and connecting rod to constitute, the variation in cutting edge gap when having avoided shearing.
The utility model purpose realizes being finished by following technical scheme:
A kind of plate shearing machine cutting edge clearance adjustment mechanism comprises upper tool post, it is characterized in that this guiding mechanism mainly is made of holder, fixed axis, regulating arm, eccentric shaft, wherein holder is fixedlyed connected with the upper tool post bottom, fixed axis is fixedlyed connected with holder, the regulating arm two ends all have the hole, the hole of one end and fixed axis movingly, the hole of the other end and eccentric shaft are movingly.
Above-mentioned fixedly connected can be that welding or bolt connect.
When the utility model used, effect was best when being separately positioned on the both sides of upper tool post.
The utility model has the advantages that, simple in structure, be rigidly connected, after the load that withstands shocks, the gap can not change, and need not frequent artificial the adjustment, and shearing quality is good.

Concrete technical scheme
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:
Shown in Fig. 1-5, label 1-24 represents respectively: lower guideway (1), guide roller (2), upper rail (3), knife rest (4), preceding precompressed guide rail (5), handwheel (6), cutter (7), workpiece (8), bottom knife (9), wallboard (10), eccentric shaft (11), upper tool post (12), holder (13), cutter (14), workbench (15), bottom knife (16), regulate bolt (17), regulate notch (18), fixed axis (19), bolt (20), regulating arm (21), regulate notch (22), regulate bolt (23), on the fixed axis with the subsides and the face (24) of holder.
Present embodiment is mainly by upper tool post (12), cutter (14), holder (13), fixed axis (19), regulating arm (21), eccentric shaft (11) constitutes, wherein cutter (14) is fixed on the upper tool post (12), holder (13) is welded on upper tool post (12) bottom, fixing between holder (13) and the regulating arm (21) by bolt (20) fixed axis (19) and that the spindle nose place is provided with, have the hole at regulating arm (21) two ends, coupling is moved with eccentric shaft (11) and fixed axis (19) respectively in the hole at these two ends, on two holes, have and regulate notch (18), (22), regulate bolt (17) by adjusting, (23) size of regulating notch (18) (22) is adjusted the size of two holes to the fastening force of eccentric shaft (11) and fixed axis (19).
When using present embodiment to carry out the adjustment of cutting edge gap, eccentric rotation axis (11), driving regulating arm (21) moves forward and backward, regulating arm (21) is done by fixed axis (19) promotion holder (13) and upper tool post (12) and is moved forward and backward, and realizes that the gap between cutter (14) and the bottom knife (16) is adjusted.
Claims (2)
1, a kind of plate shearing machine cutting edge clearance adjustment mechanism comprises upper tool post, it is characterized in that this guiding mechanism mainly is made of holder, fixed axis, regulating arm, eccentric shaft, wherein holder is fixedlyed connected with the upper tool post bottom, fixed axis is fixedlyed connected with holder, the regulating arm two ends all have the hole, the hole of one end and fixed axis movingly, the hole of the other end and eccentric shaft are movingly.
2, a kind of plate shearing machine cutting edge clearance adjustment mechanism according to claim 1, it is characterized in that described fixedly connected can be that welding or bolt connect.
