Description

An adjustable metallographic sample fixture

technical field

The utility model relates to a clamping device in the process of mechanical manufacturing, in particular to an adjustable metallographic sample clamp.

Background technique

Metallographic sample preparation is a very important part of metallographic research, which includes sample interception, sample inlay, sample polishing, sample polishing, and display of metallographic microstructure. Each process needs to strictly control the position of the sample without changing, which uses the metallographic sample fixture.

Currently commonly used metallographic sample fixtures generally include upper and lower splints, which are tightened with bolts. During use, two wrenches must be used to lock the bolts at the same time before tightening. The same is true for the loosening and unloading process. It is particularly inconvenient to use. It is also particularly troublesome, and the precision is not easy to guarantee, and because the bolts are prone to rust, the service life is short.

Utility model content

The purpose of the utility model is to provide an adjustable metallographic sample fixture which is easy to use, high in precision and long in service life in view of the deficiencies in the prior art.

The utility model is realized through the following technical solutions: an adjustable metallographic sample fixture, including a base, a blocking block arranged on the base, and a bolt connected with the blocking block, the base is movably connected with the bolt , There are two or more blocking blocks set on the base, thus avoiding the change of the position of the sample due to the position change of one of the blocking blocks, thereby increasing the scrap rate of the product.

In the adjustable metallographic sample fixture described in the utility model, the overall structure of the base is in the shape of a groove, and baffles are arranged at both ends of the base, and one side of the baffle is provided with a bolt suitable for the bolt. The threaded through hole is equipped with a precision scale line on the side of the bottom of the base, and a plurality of base positioning holes are set on the bottom of the base. The purpose of setting the precision scale line is to ensure that the distance between each blocking block and the baffle is equal , to minimize the error, the purpose of setting the base positioning hole is to control the base from displacement during the metallographic sample preparation process.

In the adjustable metallographic sample fixture described in the utility model, the said bolt is movably connected with the base through the threaded through hole provided on the baffle, and the screw top of the bolt is fixedly connected with the blocking block.

In the adjustable metallographic sample fixture described in the utility model, the blocking block can slide back and forth along the bolt direction on the base, and the distance between the blocking block and the baffle plate can be changed by adjusting the bolt.

In the adjustable metallographic sample fixture described in the utility model, the base, the blocking block and the bolts are all wear-resistant steel castings, which are wear-resistant, high-temperature resistant and corrosion-resistant.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) The adjustable metallographic sample fixture described in the utility model has a simple structure and is easy to use.

(2) An adjustable metallographic sample fixture described in the utility model is provided with two or more blocking blocks and a precision scale line is provided on the bottom side of the base, which can accurately control the position of the sample.

(3) All parts of the adjustable metallographic sample fixture described in the utility model are all wear-resistant steel castings, which are wear-resistant, high-temperature resistant, corrosion-resistant, and have a long service life.

detailed description

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example

As shown in Fig. 1, Fig. 2, and Fig. 3, an adjustable metallographic sample fixture includes a base 1, a blocking block 2 arranged on the base 1, and a bolt 3 connected to the blocking block 2. The base 1 is movably connected with the bolt 3, and there are two blocking blocks 2 set on the base 1, so it can avoid the position change of one of the blocking blocks 2, resulting in the change of the position of the sample, thereby increasing the reliability of the product. Scrap rate.

As shown in FIG. 3 , the overall structure of the base 1 is in the shape of a groove, and baffles 11 are provided at both ends of the base 1 , and a threaded through hole 111 matching the bolt 3 is provided on one side of the baffle 11 , the bottom side of the base 1 is provided with a precision scale line 12, and the bottom of the base 1 is provided with a plurality of base positioning holes 13. The purpose of setting the precision scale line 12 is to ensure the distance between each blocking block 2 and the baffle plate 11. The distances are equal to minimize errors, and the purpose of setting the base positioning hole 13 is to control the base 1 from displacement during the metallographic sample preparation process.

The bolt 3 is movably connected with the base 1 through the threaded through hole 111 provided on the baffle plate 11 , and the screw top of the bolt 3 is fixedly connected with the blocking block 2 .

The blocking block 2 can slide back and forth along the direction of the bolt 3 on the base 1 , and the distance between the blocking block 2 and the baffle is changed by adjusting the bolt 3 .

The base 1, the blocking block 2 and the bolt 3 are all wear-resistant steel castings, which are wear-resistant, high-temperature resistant and corrosion-resistant.

During the use of the present utility model, the metallographic sample is placed on the base 1 and is in contact with the side baffle plate 11 not provided with the threaded through hole 111, and then the bolt 3 is adjusted so that the two blocking blocks 2 Close to the direction of the metallographic sample, and finally in close contact with the metallographic sample, at this time, the precision scale line 12 provided on the bottom side of the base 1 ensures that the distance between the two blocking blocks 2 and the baffle plate 11 is equal, so that The preparation of the metallographic sample can be started, and after the preparation is completed, the metallographic sample can be taken out by adjusting the bolt 3 so that the two blocking blocks 2 are separated from the metallographic sample.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification or equivalent change made to the above embodiments according to the technical essence of the utility model falls within the scope of the present utility model. Within the protection scope of the present utility model.
