Description

A kind of dotter dress quickly marking casting central point

Technical field

The utility model relates to mechanical frock technical fields, more particularly to a kind of dotter for quickly marking casting central point Dress.

Background technique

With the development of mechanical manufacturing technology, the requirement of the dimensional accuracy of each assemble products from parts is more and more tighter in mechanical equipment Lattice, it is higher and higher especially for the dimension precision requirement of casting.And as casting structure becomes increasingly complex, to accomplish size In high precision, it is generally required to check the size of casting using the mode of scribing line detection in the production process of casting. In traditional scribing line detection method, casting is fixed on the square chest by periodic verification, according to the drawing of rough casting by the A of casting, B, the levelling rear progress scribing inspection of C benchmark.But since structure is complicated will cause casting in the centering mistake of scribing inspection for casting Be difficult in journey the datum level of casting is levelling, to components carry out drilling processing when, often need to find the center of components The hole for meeting position precision is attacked to bore in position, however in the prior art, for finding out the center of components, generally only lead to The width that measuring tool first measures components is crossed, using its general numerical value is calculated, reuses measuring tool cooperation Scoring tool marks center, however this method is time-consuming and laborious, and due to components appearance profile processing when inherently There is error, these errors naked eyes can not be identified, the subjective error generated when operating using personnel is missed so as to cause accumulation The increase of difference, can not really find the center of components, therefore, it is necessary to design one kind dedicated for finding out components central point Dotter dress.

In figure: 1- positioning baffle, 3- draw point pen, 4- strut, 5- datum plate, 6- pedestal, 7- supporting table, 8- casting, 601- Location hole, 801- positioning convex platform, 802- cylinder boss.

Specific embodiment

The technical solution of the utility model is described further below in conjunction with attached drawing, but required protection scope is not It is confined to described；

The utility model provides a kind of dotter dress for quickly marking casting central point, as shown in Figure 1, Figure 2, Figure 3 shows, packet Include pedestal 6 and strut 4, tool is there are two positioning convex platform 801 on casting 8, and there are two location hole 601, location holes for setting on pedestal 6 601 shape sizes and 8 positioning convex platform 801 of casting are consistent, and two location holes 601 in 6 width direction of pedestal to divide plane as mirror image Face is arranged symmetrically, and the spacing between two location holes 601 is equal with the spacing on casting 8 between two positioning convex platforms 801, strut 4 fixations are erected on pedestal 6, are provided with can slide up and down on strut 4 and are drawn point pen 3, draw point 3 central axis of pen and pedestal 6 A point plane is overlapped in width direction.

Positioning distinctive on components is utilized without using other measuring tools using the technical solution of the utility model Casting reliable and stable ground clamping on pedestal, can be connect straight the center position for finding out casting, operation by boss by stroke point Efficient and convenient, positioning convex platform is periphery on casting, and outer surface machining accuracy is high, decreases people during whole operation To intervene, to reduce the source of accumulated error, because making the center position precision found out that there is high reliability.This Outside, it is additionally provided with datum plate on pedestal, when datum plate is affixed by cast outer surface, cast(ing) surface can be put down by clearance gauge Face degree is checked, is modified to take timely measure to underproof cast product, in addition, pedestal uses stainless steel Material is made, durable, corrosion-resistant, long service life, and required maintenance cost is cheap.

Further, location hole 601 is through-hole.Fit clearance between 8 positioning convex platform 801 of location hole 601 and casting is small In 0.2mm.Also it is erected on pedestal 6 and is fixed with positioning baffle 1, positioning baffle 1 can be affixed by 8 outer surface of casting.Using this reality With novel technical solution, casting can carry out positioning and clamping by positioning baffle 1, thus make to position it is more acurrate, and in marking The position precision of heart point is also higher, more reliable.

It is slided up and down along vertical direction it is preferred that drawing a pen 3.Drawing point pen 3 is pencil or marking pen.

In addition, 8 upper surface of casting is additionally provided with cylinder boss 802, marking pen central axis and 802 central axis of cylinder boss Line coincides.Also it is erected on pedestal 6 and is fixed with supporting table 7, horizontal has datum plate 5,5 rough surface of datum plate in supporting table 7 Degree is less than Ra0.8 microns.Pedestal 6 is made of stainless steel.Datum plate 5 makes this it is also preferred that be made using stainless steel material The dotter dress that practical new model provides is more durable, when datum plate is affixed by cast outer surface, can pass through clearance gauge pair The flatness of cast(ing) surface is checked, is modified to take timely measure to underproof cast product.
