Abstract

The utility model relates to an accurate marking tool for a large-diameter ring workpiece, comprising a roller rack (2) and a main scaleplate (1), wherein both ends of the roller rack (2) are provided with supporting blocks (13), and the main scaleplate (1) with one end fixed on the roller rack is perpendicular to the roller rack and provided with scales; the roller rack is symmetrically provided with two longitudinal slotted holes (3) in which rollers (4) capable of moving along with the slotted holes are symmetrically installed, and the longitudinal centre lines of the slotted holes are positioned at the zero scale of the main scaleplate; and a vernier (7) with scales is installed on the main scaleplate, and a scriber (12) is installed at the zero scale of the vernier. The marking tool can quickly find an accurate marking position on the large-diameter ring workpiece to accomplish the marking task.

Description

The accurate scoring tool of major diameter annulus workpiece
Technical field
The utility model belongs to the scoring tool technical field.
Background technology
In machining, annular workpiece distribution circle is the important procedure of follow-up metalworking with the line of center, hole, with regard to routine operation, for the following annular workpiece line of internal diameter Φ 1500mm, the general employing at the workpiece middle part adds chock, on chock, look for the center of circle, rule by solid workpiece method with compasses again.For the above annular workpiece line of internal diameter Φ 1500mm, easily cause the line error excessive with the method that adds chock.So someone adopt a kind of easy band roller and be the marking-out rule of the band scriber of benchmark, its method is on the annular workpiece, with interior circle or cylindrical is benchmark measures distribution circle with ruler position, center-punching marks the distribution circle diameter with this marking-out rule again, then symmetrical measurement distribution circle diameter, if error is arranged with institute's dimensioning on the drawing, regulate the scriber position with estimation approach again, try again to draw, till meeting the demands.The shortcoming of this method is that operation is cumbersome, and the accuracy of line too relies on operator's level of skill.
Summary of the invention
The purpose of this utility model is to solve prior art problems, and a kind of accurate scoring tool that can find scribing position accurately rapidly and finish line work on major diameter annulus workpiece is provided.
The purpose of this utility model is achieved by the following technical solution.
The accurate scoring tool of major diameter annulus workpiece comprises that the turning rolls of two ends band rest pad, an and end vertical with turning rolls are fixed in the main scale that has scale on the turning rolls; Symmetry offers two long slot bores longitudinally on turning rolls, is symmetrically installed with to move the roller of adjusting along long slot bore in two long slot bores, and the longitudinal centre line of long slot bore is positioned on the zero graduation of main scale; The vernier scale of band scale is installed on main scale, scriber is installed at the zero graduation place of vernier scale.
The utility model is positioned at the vernier scale outer end regulating block is installed on main scale, be separately installed with adjustment screw, fine-tuning nut in the top and the bottom of regulating block.Described scriber is carbide alloy or high-speed steel scriber.On the central shaft of roller, fastening screw nut is installed.
Ingenious, the simple and direct practicality of the utility model design, easy operating, line precision height can find accurately scribing position to finish line work rapidly, can be applicable to the accurate line work of all kinds of major diameter annulus workpiece.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is the schematic diagram of the utility model and line thereof.
The specific embodiment
As shown in the figure, the utility model comprises the turning rolls 2 that fixedly mounts roller 4, the main scale that have exact scale 1 vertical with turning rolls, and an end of main scale fixedly mounts or is welded on the turning rolls.Turning rolls two ends band can increase bearing-surface makes the reliable rest pad 13 of smooth operation, symmetry offers two long slot bores 3 longitudinally on turning rolls, roller 4 symmetries are installed in two long slot bores and can move adjusting along long slot bore, and the longitudinal centre line of long slot bore overlaps with main scale zero graduation line; Roller can be selected standard rolling bearing for use.The vernier scale 7 of band scale is installed on main scale, carbide alloy or high-speed steel scriber 12 is installed, the zero graduation line of scriber centrally aligned vernier scale on vernier scale.Be fitted with adjustment screw 6 on the vernier scale, the degree of tightness of adjusting should make vernier scale slide freely.On main scale, be positioned at the vernier scale outer end regulating block 9 is installed, be separately installed with adjustment screw 8 and fine-tuning nut 10 and fine setting screw rod 11 in the top and the bottom of regulating block.Fastening screw nut 5 is installed on the central shaft of roller 4.
Regulate the big I free adjustment of roller spacing P, when drawing large-diameter workpiece spacing P is transferred greatly, when drawing small diameter workpiece spacing P is turned down, to help operation according to the diameter of work of drawing.
When using the utility model line, only need to calculate earlier the scale size A value that main scale shown in publishing picture need be regulated, adjusting by regulating block 9, adjustment screw 8, fine-tuning nut 10 and fine setting screw rod 11, mix up the vernier scale position, the scriber position is pressed after the A value sets up, can promote roller and roll along circle or cylindrical in the workpiece, when roller rolled, scriber was promptly rule on workpiece.
The computational methods of A value are as follows: with circle in the workpiece H is benchmark, also tightens up known roller radius r, workpiece diameter R with fastening screw nut 5 according to circle diameter size adjustment roller spacing P 1, distribution circle diameter R 2, be calculated as follows out the A value:
A = R 2 - ( R 1 - r ) 2 - 0.25 P 2
The precision of vernier scale can be generally ± 0.02mm by the used slide measure precision of prior art, and therefore, even if consider the accumulated error of each side, the dimensional accuracy of the utility model line can reach ± 0.20mm at least, can satisfy specification requirement fully.
The utility model is used the precision vernier callipers principle dexterously, and the A value that calculates is directly adjusted scale on the scoring tool as sized data, with screw and tight vernier scale, directly marks the distribution circle diameter on workpiece.
