Abstract
The invention relates to a marking tool. The marking tool comprises a workpiece, wherein the outer round edge of the workpiece is provided with a locating plate; one end of the locating plate is provided with a V-shaped surface which is matched with and propped against the outer round edge of the workpiece; the upper part of the locating plate is provided with a clamp body; a marking plate penetrates through the middle part of the clamp body; the marking plate on the clamp body is locked on the locating plate through a fastener; and one end of the marking plate is provided with a marking needle. The marking tool disclosed by the invention is simple in structure, low in manufacturing cost, and convenient to install and operate; the locating plate is matched with the clamp body, so that the marking tool can mark accurately without aligning a centre point, thus overcoming the defect of the prior art that the centre point is difficult to be aligned for marking large workpieces; and the marking tool can mark a required centre circle based on the outer circle of the workpiece, so that the part of the workpiece to be machined can be conveniently determined, the workpiece can be accurately machined to form a finished product, the machining precision of the product can be ensured, the production efficiency can be improved, and cost can be lowered.
Description
Technical field
The present invention relates to the aid for workpiece process, especially a kind of scoring tool for the annular workpiece.
Background technology
At present, in the actual machine process, line be each workpiece from blank to the finished product process an indispensable procedure, be widely used among single-piece or the small lot batch manufacture, the workpiece size all needs to rule in process, thereby be convenient to determine the Working position of processing work, and the height of line precision will directly affect the crudy of workpiece, often to draw round wire and straight shape line at workpiece in the actual production, when drawing round wire the center of circle and radius need to be arranged, but for large-scale workpiece, because of the restriction of the length of being plan, plan and correctly to mark; When processing annular workpiece, such as a plurality of screw mounting holes on the processing annulus flange periphery, because the middle part of flange is hollow, its centre point is removed, and is difficult to directly mark the center circle of screw hole in addition; In order accurately to mark required center circle, need to fill up at hollow parts, fill centre point, then utilize compasses to mark center circle, not only operating efficiency is lower, troublesome poeration, the centre point error is larger; On the other hand, as being provided with boss in the middle of the processing flange, because the restriction of structure can't be found out centre point at its home position, so can't mark the center circle of required processing, affected the processing of the next process of workpiece.
Summary of the invention
The applicant in the above-mentioned existing production technology to annular workpiece line troublesome poeration, be difficult to find out the center of circle, there are the shortcomings such as larger error in line, provide scoring tool a kind of rational in infrastructure, easy to operate, thereby line is convenient, simple and practical, labor strength is low, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
A kind of scoring tool comprises workpiece, and the outer circumferential edge place of described workpiece is provided with location-plate, and described location-plate one end arranges the V-arrangement face, the V-arrangement face of the described location-plate butt that matches with the outer circumferential edge of workpiece; Described location-plate top mounting clamp is concrete, and marking-off plate is crossed at described clamp body middle part, and by securing member it is being lock onto on the location-plate on the clamp body, and described marking-off plate one end is provided with scriber.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, low cost of manufacture, installation and use is convenient, by being used of location-plate and clamp body, need not to look for centre point to rule accurately, overcome in the prior art difficult defective of finding center of circle line accurately on large-scale workpiece, by scoring tool of the present invention, as benchmark, mark needed center circle with excircle of workpiece, determine easily the required Working position of workpiece, thereby process accurately the workpiece finished product, guarantee the machining accuracy of product, improved production efficiency, reduced cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, scoring tool of the present invention is when being applied to process screw mounting hole on the annulus flange, comprise annulus flange 5, the outer circumferential edge place of annulus flange 5 is provided with location-plate 3, and location-plate 3 one ends arrange the V-arrangement face, the V-arrangement face of location-plate 3 butt that matches with the outer circumferential edge of workpiece 5; Location-plate 3 top mounting clamps concrete 2, marking-off plate 1 is crossed at clamp body 2 middle parts, and it is being lock onto on the location-plate 3 by screw 6 on the clamp body 2, and marking-off plate 1 one ends are provided with scriber 4, marking-off plate 1 can be in clamp body 2 interior move left and right, to use on the workpiece that is applicable to the different structure size.
In the actual use procedure, butt at first matches with the location-plate 3 V-arrangement face of opening at the cylindrical place of annulus flange 5, both near, then at the top of location-plate 3 mounting clamp concrete 2, marking-off plate 1 is crossed clamp body 2 middle parts, and fastening by two screws 6, can be according to the requirement of different annulus flange 5 sizes, by move left and right scriber 4, regulate scriber 4 desired locations, guarantee the position of scriber 4 on the center circle of needs, annulus flange 5 maintains static at this moment, location-plate 3 rotates a circle around the cylindrical of annulus flange 5, and 4 lines that mark at annulus flange 5 upper surfaces of scriber are exactly needed center circle; According to the quantity of screw hole, divide equally the arc length of this center circle at last, just can determine the position of screw hole, can process accurately screw hole of position.The present invention not only processes easy to use, and the line precision is high.
More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
