Description

Test sample cutter

The utility model is a kind of test specimen cutting press.

The test specimen cutting press that uses and supply in the market, its clamp mechanism mostly is manually parallel clipping, system utilizes 2 acting forces that sample is clamped, but because specimen shape, not of uniform size, so extremely difficult clamping, and, cause grinding wheel and sample to split cruelly because the torsional interaction of grinding wheel very easily causes the sample displacement.

The purpose of this utility model is to be to provide a kind of simple in structure, easy to operate and safe, practical, test specimen cutting press that the emery wheel loss is few

For achieving the above object, the utility model adopts the clamp mechanism of being made up of vee-block, base, support, pressing plate and oil cylinder, utilization is contained in afterbody has the pivot pin in the earrings hole of pressing plate of two earrings to be connected with the oil cylinder shaft, the effect of mat oil cylinder hydraulic makes the pressing plate head produce a downward normal pressure to the sample that is placed on the base vee-block, form 3 clampings, sample can be clamped, avoid displacement, and cut down steadily.

The utility model has the advantages that: 1) simple in structure, easy to operate; 2) feel is light when cutting, vibrates for a short time, and noise is low; 3) can adapt to the cutting needs of various sample; 4) can reduce grinding wheel and split cruelly, reduce expenses.

Fig. 1, Figure 2 shows that the utility model vertical view and front view.

Figure 3 shows that the utility model hydraulically operated fixture structural representation.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 and Fig. 2 show the structure of cutting mechanism of the present utility model and control gear and form.
