Description

A kind of steel plate shearing machine load bearing holder mounting structure
Technical field
The present invention relates to a kind of steel plate shearing machine, especially a kind of steel plate shearing machine load bearing holder mounting structure.
Background technology
In steel plant, steel plate shearing machine is the equipment for shearing steel plate on steel plate production line.Steel plate shearing machine load bearing block refers in steel plate shearing machine, for installing the installation bearing of the line shaft be directly connected with cutting mechanism (i.e. shearing machine).Because line shaft is used for cutting mechanism power transmission, therefore during the work of load bearing block, need the larger active force born from cutting mechanism, so stability when wanting installation shaft bearing to work, during installation shaft bearing, need bottom bearing block with mounting groove clamping to improve installation reliability, but after clamping with mounting groove bottom bearing block, because when bearing block works, load can produce certain distortion, therefore cause, when needs dismounting bearing block, being difficult to the dismounting completing bearing block quickly and easily.
So, how to design a kind of bearing holder mounting structure, make when installation shaft bearing, can either guarantee that it installs stability, again can be for convenience detach, become the problem needing to be considered.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is, steel plate shearing machine load bearing block installs stability how to provide one to guarantee, can facilitate again the steel plate shearing machine load bearing holder mounting structure that it is dismantled.
In order to solve the problems of the technologies described above, in the present invention, have employed following technical scheme:
A kind of steel plate shearing machine load bearing holder mounting structure, comprise frame and bearing block, described frame is provided with mounting groove, described bearing block is arranged in mounting groove, it is characterized in that, described bearing block direct-axis has a perpendicular to the side bottom of length direction, be positioned at this perpendicular outer fix in described mounting groove and also positioning key be installed, described positioning key along axial direction both sides and to install between cell wall and described perpendicular be the tight fit after fit, described positioning key is also provided with the bolt being passed down through positioning key and frame and realizing fixing.
In the present invention, in the mounting groove of bearing block side, be provided with positioning key, positioning key is that tight fit is arranged.Therefore when installation shaft bearing, when bearing block is installed on after in mounting groove, again positioning key can be built and form tight fit into bearing block side, described in be a tight fit in and degree refer to positioning key needs can load and can produce after said fitting to be out of shape to be pushed against by bearing block side a little.Like this, when bearing block is installed, build tightening position by positioning key, reliability is fixed in the installation that can improve bearing block, improves and installs stability, make it operationally can bear the active force of cutting mechanism better, guarantees carrying out smoothly of shearing.Meanwhile, when maintenance needs dismounting, only need first to disassemble positioning key, after positioning key dismounting, there is gap between bearing block and mounting groove, therefore the dismounting of bearing block can be completed easily.Like this, owing to directly dismantling positioning key than directly dismounting bearing block is more convenient, therefore improve dismounting convenience.
As optimization, described positioning key is also provided with the screwed hole of up/down perforation.Described screwed hole is used for when dismantling positioning key, adopts the bolt of coupling to be screwed in screwed hole to be ejected by positioning key.After such optimization, can the dismounting of convenient positioning key.Owing to being that tight fit is installed when positioning key is installed, bearing block operationally simultaneously, can bear the active force from cutting mechanism and high vibration, therefore easily cause positioning key to be out of shape, and makes it be difficult to dismounting smoothly.General method for dismounting is for first to weld a block plate on positioning key, then adopt jack up to be pushed up by steel plate in both sides, by up pushing up steel plate, positioning key being taken out of, needing again when positioning key being ejected complete installations of rear maintenance again by steel plate excision, therefore still bothering very much.And on positioning key after optimal design-aside screwed hole, when dismantling positioning key, only need screw in bolt in screwed hole, after mounting groove bottom surface is withstood in bolt lower end, continuing swivel bolt can eject positioning key, improves positioning key and removes convenient degree.
As further optimization, described bolt has three and is uniformly vertically arranged in the middle part of positioning key, and described screwed hole has two and lays respectively at the position between three bolts.After such optimization, when positioning key being fixed and dismantles, exert a force more balanced.
In sum, steel plate shearing machine load bearing holder mounting structure of the present invention, has and can guarantee that steel plate shearing machine load bearing block installs stability, can facilitate again its advantage dismantled, and can guarantee carrying out smoothly and improving the convenient degree of overhauling of production.

Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of steel plate shearing machine load bearing holder mounting structure, comprise frame 1 and bearing block 2, described frame 1 is provided with mounting groove, described bearing block 2 is arranged in mounting groove, wherein, described bearing block 2 direct-axis has a perpendicular to the side bottom of length direction, be positioned at this perpendicular outer fix in described mounting groove and positioning key 3 is also installed, described positioning key 3 along axial direction both sides and to install between cell wall and described perpendicular be the tight fit after fitting, described positioning key 3 is also provided with and is passed down through positioning key 3 and frame 1 and realizes fixing bolt 4.During concrete enforcement, described positioning key is also provided with the screwed hole 5 of up/down perforation.Described bolt 4 has three and is uniformly vertically arranged in the middle part of positioning key, and described screwed hole 5 has two and lays respectively at the position between three bolts 4.
In addition, when specifically implementing, described screwed hole is the screw of M27, and the screw thread of this screw can bear the power that ejected by positioning key better and be unlikely to damage.
In the present invention, in mounting groove, set up positioning key, the installation of bearing block can have been facilitated to fix and dismantle, and then positioning key has been set up screwed hole, the dismounting of positioning key self can be facilitated, therefore there is field-strip conveniently advantage.
