Description

Clamp for metallographic detection

Technical Field

The utility model relates to an anchor clamps equipment technical field that the metallography detected, concretely relates to anchor clamps for metallography detects.

Background

At present, when metallographic examination, form the sample intermediate layer through adding the copper sheet between two samples, then fix through anchor clamps, polish the surface on sample intermediate layer again, detect the observation through the sight glass at last.

Traditional metallographic detection anchor clamps, it is less because of detecting the appearance piece size, reasons such as the shape is not standard lead to fixed effect relatively poor, inconvenient grinding and polishing, it is more convenient all to adopt the mode of inlaying to make the sample throw the mill (to wait to detect the appearance piece buries in the mould that is equipped with the mosaic material, make its solidification under the condition of heating pressurization), form this kind of inlayed method of sample though can solve the problem of throwing the mill difficulty, but need the inlaying machine, inlay material etc. can make cost increase to a certain extent, secondly, the heating pressurization, the process such as drawing of patterns needs the longer time, can not guarantee the promptness that detects.

Also have simultaneously and directly fix through anchor clamps and polish the detection, but this type of anchor clamps are when polishing the sample, injure the finger easily, and fixed effect is not good moreover.

Traditional metallography detects anchor clamps, and the efficiency that detects reduces, when the sample is more, can't satisfy the detection demand.

To this end, we propose a fixture for metallographic examination.

FIG. 1 is a schematic perspective view of the present invention;

fig. 2 is a schematic top view of the structure of the present invention.

In the figure: the test device comprises a base 1, a connecting piece 2, a fixing hole 3, a screw rod 4, a knob 5, a rubber sleeve 6, a rubber pad 7, a first test sample a, a second test sample b and a copper gasket c.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to the attached drawings 1-2, the fixture for metallographic detection comprises a base 1 and a connecting piece 2 connected to the base 1, the fixture is convenient to hold by the aid of the connecting piece 2, fingers are prevented from being injured by a grinding machine, and the fixture is convenient and practical.

Set up the fixed orifices 3 of two symmetries that link up each other on base 1 and the connecting piece 2, can conveniently carry out the fixed polishing to a plurality of sample intermediate layers through setting up two fixed orifices 3, the efficiency that detects is improved, equal screw thread grafting has screw rod 4 on two 3 relative lateral walls of fixed orifices, two 4 relative one ends of screw rod all are connected with knob 5, cooperation through screw rod 4 and knob 5 is fixed, improve fixed effect, be different from traditional mode of inlaying, can fix the less each different sample of shape of size, make things convenient for follow-up burnishing and polishing simultaneously, the work efficiency is improved, the cost is reduced, and this anchor clamps application scope is wide, the sample that is fit for various shapes detects, also be fit for the metallography detection of thin slice (thin wall) class product appearance piece simultaneously.

In this embodiment, as shown in fig. 1 and 2, the base 1 and the connecting member 2 are integrally formed, which facilitates processing.

In this embodiment, as shown in fig. 1, the height of the connecting piece 2 is greater than two centimeters, and the side wall of the connecting piece 2 is provided with anti-slip lines, so that an operator can conveniently hold the connecting piece 2 to perform polishing operation, and the fingers of the operator can be protected.

In this embodiment, as shown in fig. 1 and 2, two rubber sleeve 6 has all been cup jointed to the one end that screw rod 4 is relative, two all be connected with rubber pad 7 on the relative lateral wall of fixed orifices 3, through above-mentioned cooperation, can improve with the interbedded linkage effect of sample, improve fixed strength, make the connection between first sample an, second sample b and the copper gasket c inseparabler, also can not damage the surface of sample simultaneously.

In this embodiment, base 1 and connecting piece 2's surface all is through nitrogen carbon oxygen combined treatment, through carrying out nitrogen carbon oxygen combined treatment to base 1 and connecting piece 2's surface, corrosion resistance and wearability that can improve because the sample need carry out corrosive agents such as alcohol and corrode, so base 1 and connecting piece 2 also corrode indirectly easily, and adopt nitrogen carbon oxygen combined treatment back, can improve corrosion resistance and wearability, can effectively protect base 1 and connecting piece 2, have improved life greatly.

The working principle is that a copper gasket c is placed between a first sample a and a second sample b to form a sample interlayer, the formed sample interlayer is placed in a fixing hole 3, the knob 5 is rotated to drive a screw rod 4 to rotate and clamp the sample interlayer, and meanwhile, the clamping effect can be improved through a rubber sleeve 6 arranged on the screw rod 4 and a rubber pad 7 arranged in the fixing hole 3, so that the connection of the copper gasket c and the second sample b is tighter, the shaking of the sample interlayer during subsequent polishing can be reduced, the polishing effect is influenced, the subsequent detection is influenced, the surface of the sample is not easily damaged, and the sample interlayer is fixed;

then through the both sides of handheld connecting piece 2, be close to the polisher with the diapire of base 1, make the polisher can polish the sample intermediate layer, because the area of base 1 is great, can play certain protection effect to the finger.

And because the quantity of fixed orifices 3 is two, can fix simultaneously and polish a plurality of samples, improve the efficiency of fixed polishing.
