A kind of special scribing block
Technical field
The utility model belongs to pincers worker and assembling field of hand, relates in particular to a kind of special scribing block.
Background technology
The scoring tool that scriber is basic as a kind of pincers worker, that in machining and metal structure manufacture, uses is very general.In machining, usually can run into such situation, a part, in the processing and manufacturing process, according to drawing requirement, still has the further processing processing such as some ,Cao, corners, hole.In first being processed, need scriber for bench workers to mark accurate Working position.
But along with the development of mechanical processing industry, the workpiece size of facing during bench work is increasing at present, and existing scribing block regular size≤1500mm.Therefore, when pincers worker, to the large-size workpiece operation time, when instrument surpasses maximum specification commonly used, need to use the scribing block cooperation to meet the face plate line of required precision.This class methods operable area limitation, need segmentation to rule continuously.Simultaneously, the line error caused due to the movement of the strain of scriber and tosecan itself increases, and then has influence on the machining accuracy of subsequent workpiece.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of special scribing block for deficiency of the prior art, effectively increases the line scope, and the rigidity requirement of scriber while meeting large workpiece line, improve the line precision.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of special scribing block, comprise base, column, scriber and the clamping structure for column and scriber are fixed together, and described column is arranged on base, and column is selected square tube, depending on the line demand, selects appropriate length, and is provided with chute one on its length direction.Described scriber one end is provided with the straight knife head for line, and the other end is provided with for drawing the tulwar head of the positive location of workpiece, and scriber is provided with chute two in the longitudinal direction.
Further, described clamping structure comprises stud sides clamp, scriber side clamp, clamping screw and locking nut, described stud sides clamp is installed in chute one, scriber side clamp is installed in chute two, can rotate with the adjusting of scriber angle, described clamping screw successively through stud sides clamp, column, scriber with scriber side clamp together with locking nut screwing.
Further, described base comprises base plate and installing plate, and described column is fixedly mounted on installing plate, and installing plate is bolted on base plate.Base plate is foundry goods, upper and lower plane precision process, and installing plate adopts the steel plate of 10-20mm thickness, convenient in carrying.Base plate thickness is large, reduces the scribing block center of gravity, avoids in scratching process, and scribing block tilts.
Further, the chute one on described column at least is provided with two, and the chute two on scriber also at least is provided with two, increases as far as possible the adjustable extent of scriber in the rigidity that guarantees column.
Further, the end that described scriber is provided with the tulwar head also is provided with the protection nut, and the protection nut is threaded connection and is arranged on the tulwar head.In line and depositing process, consider security, the tulwar head screws on the protection nut in obsolete situation.Preferably, be provided with fixing handle on described locking nut, facilitate many scribers to carry out quick adjustment.
Further, between described column and installing plate, be provided with reinforcement, an end of described reinforcement is fixed by welding in the middle and upper part of column, and the other end is fixed by welding in the upper surface of installing plate, to improve the overall construction intensity of whole scribing block.
The accompanying drawing explanation
The idea figure that Fig. 1 is the special scribing block embodiment of the utility model.
The side view that Fig. 2 is the special scribing block embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
As illustrated in fig. 1 and 2, the embodiment of the special scribing block of the utility model, comprise base 1, column 4, scriber 6 and the clamping structure 7 for column 4 and scriber 6 are fixed together, described column is installed on base 1, described column 4 adopts square tube and add the chute 1 for scriber is installed on its length direction, described scriber 6 one ends are provided with the straight knife head 8 for line, and the other end is provided with for drawing the tulwar head 51 of the positive location of workpiece, and centre arranges chute 2 61.
Described clamping structure 7 comprises stud sides clamp 72, scriber side clamp 73, clamping screw 71 and locking nut 74, described stud sides clamp 72 is installed in chute 1, scriber side clamp 73 is installed in chute 2 61, and described clamping screw 71 is tightened and is fixed together with locking nut 74 through stud sides clamp 72, column 4, scriber 6 and scriber side clamp 73 successively.
Described base 1 comprises base plate 11 and installing plate 12, and described column 4 is fixedly mounted on installing plate 12, and installing plate 12 is connected by bolt 3 with base plate 11.
Chute 1 on described column 4 at least is provided with 2, and the chute 2 61 on scriber 6 also at least is provided with 2, can increase as far as possible the adjustable extent of scriber in the rigidity that guarantees column.The chute one of the present embodiment and chute two are two.
Described tulwar head 51 also comprises protection nut 52, and protection nut 52 is connected with tulwar head 51 by screw thread.Be welded with handle 75 on described locking nut 74.
Be provided with reinforcement 9 between described column 4 and installing plate 12, an end of described reinforcement 9 is fixed by welding in the middle and lower part of column 4, and the other end is fixed by welding in the upper surface of installing plate 12.
While using scribing block, base plate 11 is positioned on face plate to the suitable position apart from workpiece.By scribing block installing plate 12, by bolt 3, install fixing.Select the scriber 6 of appropriate size, it is close to column 4, stud sides clamp 72 is installed, and makes clamping screw 71 successively through stud sides clamp 72, column 4, scriber 6 and scriber side clamp 73, fixing with locking nut 74.In use procedure, revolve the jack panel 74 that undoes the lock, according to the requirement of workpiece size and line and centering, regulate the collapsing length of scriber 6, and with the relative position of column 4 after, screw locking nut 74.After wouldn't using or finish using, scriber straight knife head 8 should be vertically downward, and scriber centering end 51 screws on protection nut 52, in case hurt sb.'s feelings and reduce shared locus.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
