The utility model discloses a rotatory screw rod, it is further fixed with the round pin axle in the spacing angle bar recess, prevent effectively that the round pin axle takes place an offset in drilling process, problem that the precision that leads to punching descends, its easy operation, labour saving and time saving, stability is high to improve the qualification rate of product, and then improved the production efficiency of enterprise.

Description

A kind of bearing pin central punch frock
Technical field
This utility model relates to crane machine manufacture field, especially relates to a kind of bearing pin central punch frock.
Background technology
At present, at crane machine manufacture field, the central punch process of bearing pin is wherein related to.In existing enterprise technology, the position lacking bearing pin limits mechanism, when using bearing pin central punch frock, it is frequently encountered by the skew of bearing pin position, cause the problem that punching precision declines, the qualification rate not only making bearing pin product declines, and wastes substantial amounts of time, man power and material simultaneously, and this brings huge loss to enterprise.
Utility model content
The purpose of this utility model is to provide a kind of bearing pin central punch frock, overcomes the defect of prior art, solves bearing pin and occur position to offset in boring procedure, causes precision decline of punching, poor stability, the problem that conforming product rate is low.
In order to achieve the above object, this utility model have employed techniques below scheme:
A kind of bearing pin central punch frock, including workbench, described workbench is provided with base plate, and described base plate is secured by bolts on workbench.
Further improvement of the utility model scheme is, described base plate is provided with spacing angle bar, and described spacing angle bar is perpendicularly fixed on base plate by welding;The groove dead ahead of described spacing angle bar is provided with pole, and described pole is perpendicularly fixed on base plate, and described pole top is fixed with erect type nut, and the screw of described nut is right against the groove of spacing angle bar, and described screw female thread connects screw rod.
Further improvement of the utility model scheme is, the back side of described spacing angle bar is fixed with support bar.
Further improvement of the utility model scheme is, described support bar is fixed on spacing angle bar upper rear portion by welding, one end, and the other end is fixed on base plate.
Further improvement of the utility model scheme is, the centrage of described screw and spacing angle bar texturearunaperpendicular.
Further improvement of the utility model scheme is, the centrage of described screw rod overlaps with the centrage of screw.
Further improvement of the utility model scheme is, is placed with bearing pin in the groove of described spacing angle bar, and the surface of described bearing pin is provided with drill.
Further improvement of the utility model scheme is, the central axis of described drill and the central axes of bearing pin.
Compared with prior art, the beneficial effects of the utility model are:
This utility model passes through rotary screw, bearing pin in spacing angle bar groove is fixed further, it is effectively prevented bearing pin in boring procedure and position skew occurs, cause the problem that punching precision declines, it is simple to operate, time saving and energy saving, and stability is high, thus improve the qualification rate of product, and then improve the production efficiency of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is workbench, and 2 is base plate, and 3 is bolt, and 4 is pole, and 5 is nut, and 6 is screw rod, and 7 is bearing pin, and 8 is angle bar, and 9 is support bar, and 10 is drill, and 11 is screw.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model, it should be understood that following detailed description of the invention is merely to illustrate this utility model rather than limits scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of utility model.
Embodiment 1: a kind of bearing pin central punch frock as shown in Figure 1, including workbench 1, described workbench 1 is provided with base plate 2, and described base plate 2 is fixed on workbench 1 by bolt 3;Described base plate 2 is provided with spacing angle bar 8, and described spacing angle bar 8 is perpendicularly fixed on base plate 2 by welding;The groove dead ahead of described spacing angle bar 8 is provided with pole 4, and described pole 4 is perpendicularly fixed on base plate 2, and described pole 4 top is fixed with erect type nut 5, and the screw 11 of described nut 5 is right against the groove of spacing angle bar 8, and described screw 11 female thread connects screw rod 6;The back side of described spacing angle bar 8 is fixed with support bar 9, and described support bar 9 is fixed on spacing angle bar 8 upper rear portion by welding, one end, and the other end is fixed on base plate 2;
The centrage of described screw 11 and spacing angle bar 8 texturearunaperpendicular, the centrage of described screw rod 6 overlaps with the centrage of screw 11;Being placed with bearing pin 7 in the groove of described spacing angle bar 8, the surface of described bearing pin 7 is provided with drill 10, the central axis of described drill 10 and the central axes of bearing pin 7.
A kind of bearing pin central punch frock that this utility model provides, during work, is first positioned over bearing pin in the groove of spacing angle bar 8, then rotary screw 6, is further secured in spacing angle bar 8 groove, drill 10 of finally leaving behind, holes bearing pin 7.This utility model passes through rotary screw, bearing pin in spacing angle bar groove is fixed further, it is effectively prevented bearing pin in boring procedure and position skew occurs, cause the problem that punching precision declines, it is simple to operate, time saving and energy saving, and stability is high, thus improve the qualification rate of product, and then improve the production efficiency of enterprise.
