detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

Referring to Fig. 1 and Fig. 2, a back-adjustment-type casting blank flatness detection device for aligning the processing datum includes a base plate 7, a contour block 5 arranged on the base plate 7, a moving rod 2, and a plurality of workpieces for limiting the position of the workpiece. The limit column 3 and a plurality of support columns that support the workpiece, wherein,

The number of the equal-height blocks 5 is multiple and they jointly accept the moving rod 2;

A dial indicator base 1 is placed on the moving bar 2 for installing the dial indicator, the length of the moving bar 2 extends along the left-right direction, and the moving bar 2 is provided with a dial indicator base as the dial indicator base. 1. The guide channel of the moving channel, the longitudinal direction of the guide channel is consistent with the longitudinal direction of the moving rod 2; the guide channel on the moving rod 2 can make the dial indicator base 1 move left and right on the moving rod 2. In addition, Travel bar 2 can move back and forth on equal height block 5.

The limit column 3 can fix the position of the workpiece to avoid inaccurate measurement results caused by the movement of the workpiece after it is fixed.

At least one of the supporting columns is an adjustable supporting column 4, and the adjustable supporting column 4 includes a column base and a column rod, and the column base is fixedly installed on the base plate 7, and the column rod is vertically arranged and threaded connected to the column seat; the top surface of each support column is a plane.

Further, the left and right ends of the moving rod 2 are respectively provided with limiting parts for limiting the left and right displacement of the moving rod 2; the limiting parts include bolts and nuts threaded on the bolts, and the The bolt passes through the moving rod 2.

Further, the front and rear ends of the equal height block 5 are provided with limiting bosses 51 for limiting the front and rear displacement of the moving rod 2 .

Further, three limiting columns 3 and three supporting columns can be designed here according to requirements. According to the stability of the triangle, the three limiting columns 3 are arranged in a triangle, and the three supporting columns are also arranged in a triangle. If three support columns are selected, the height of one of the support columns is non-adjustable. This support column is a fixed support column 8, and the other two are adjustable support columns 4. When testing, the fixed support column 8 is used to support the casting blank Return the dial indicator to zero, then move the dial indicator to the position of an adjustable support column 4, adjust the height of the adjustable support column 4 to reset the dial indicator to zero, and then move the dial indicator to another adjustable support column 4 position, adjust the height of the adjustable support column 4 again to make the dial indicator return to zero.
