Description

Equal-height sleeve or equal-height column grinding clamp

Technical Field

The utility model belongs to the field of machining equipment, and particularly relates to a grinding clamp for a constant-height sleeve or a constant-height column.

Background

The equal-height sleeve or the equal-height column is a mechanical part commonly used in the mechanical assembly and manufacture, and the equal-height sleeve or the equal-height column is commonly used in the mould manufacture, such as a punching mould, a drawing mould and the like; the height difference of the equal height column or the equal height sleeve used with the die is required to be smaller than 0.05mm. In the machining process, the external dimension is machined by adopting a lathe, grinding allowance is reserved in the axial (height) direction, and then the axial dimension of a plurality of equal-height sleeves or equal-height columns is machined to the dimension required by the drawing by adopting a grinder. However, in actual production and manufacture, the grinding of the shaft sleeve or the shaft column is difficult, and the grinding is mainly performed by: (1) The diameter of the device is smaller, the contact area with a grinding machine is small, the adsorption capacity of the grinding machine electromagnetic disc is limited, and the device is unstable in a contour sleeve or a contour column and moves; (2) The height dimension of a plurality of equal height sleeves or equal height columns is difficult to ensure consistency, and the processing precision is low.

For the above problems, a device for firmly clamping the equal-height column is needed to be provided for the equal-height column, in the prior art, an equal-height sleeve or an equal-height column is generally clamped by an upper flat tongs, and then two ends of the equal-height sleeve or the equal-height column are ground by a plane grinding device, but the following problems still exist:

1. because the outer diameter of the equal-height column or the equal-height sleeve does not have the precision requirement, the equal-height column or the equal-height sleeve is generally roughly machined, the machining error is more than 0.2mm, and each part is difficult to tighten;

2. because the jaw width of the flat tongs is limited, the maximum clamping of 3 pieces is generally carried out, and the processing efficiency is low;

3. the flat tongs are clamped and subjected to flat grinding, and the possibility that the clamping is not tight exists, so that the risk that the constant-height sleeve flies out in the flat grinding process exists, and potential safety hazards exist.

4. The equal-height precision is poor. The flat tongs are clamped for a plurality of times, the clamping times are more, the precision is poor, and the high precision of the same batch is more than 0.05 and less than 0.1.
