Description

Technical Field

[0001] This utility model relates to a clamping device, and more particularly to a mushroom-shaped primary aluminum sampling and fixing device, belonging to the field of primary aluminum sampling technology. Background Technology

[0002] When performing elemental chemical analysis at different stages of primary aluminum sampling, aluminum shavings need to be drilled from the sample. During drilling, the shavings should be thin and flaky for easy weighing later. Since our analysis involves approximately three experiments per month, purchasing high-end machine tools is too expensive; therefore, we use a small bench drill. There are certain requirements for the sample quantity during drilling, often requiring drilling at least two borehole diameters. This necessitates multi-step sampling, resulting in stepped samples, commonly known as mushroom-shaped samples. During sampling, the mushroom-shaped sample must be placed on the drill bench vise. However, this process has the following drawbacks: ① When the mushroom-shaped sample is mounted on the drill bench vise, the vise opening is often unstable, causing the primary aluminum sample to flip, potentially leading to accidents. Furthermore, the process requires constant translation of the mushroom-shaped sample, which is time-consuming, labor-intensive, and inefficient. ② Drilling generates a large amount of aluminum shavings, which fall around the sample, are difficult to collect, and easily cause contamination. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mushroom-shaped primary aluminum sampling and fixing device that can fix the mushroom-shaped primary aluminum, making it convenient for workers to perform sampling operations. At the same time, the aluminum shavings generated during drilling will remain in the receiving groove, avoiding pollution.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A mushroom-shaped primary aluminum sampling and fixing device includes a receiving groove, which is distributed in a circular barrel shape. Three tightening bolts are evenly arranged on the outer wall of the receiving groove. The tightening bolts pass through the receiving groove and are fixedly connected to the receiving groove by threads. A handle is provided on the outside of the receiving groove.

[0006] The container is filled with mushroom-shaped aluminum, the height of which is twice the height of the mushroom-shaped aluminum, and the inner diameter of which is greater than the outer diameter of the large opening of the mushroom-shaped aluminum.

[0007] The three tightening bolts are distributed in an isosceles triangular shape in the cross-section of the receiving groove, and the tightening bolts are located at the lower middle position of the outer wall of the receiving groove.

[0008] The receiving groove is distributed with the upper port open and the lower port closed.

[0009] The positive and beneficial effects of this utility model are:

[0010] 1. This utility model uses three tightening bolts evenly arranged on the outer wall of the receiving groove to clamp and fix the mushroom-shaped aluminum in the receiving groove. With the use of the handle, it can prevent the mushroom-shaped aluminum from flipping over during the drilling process, thus ensuring the safety of construction. At the same time, the workers can freely move the mushroom-shaped aluminum according to the drilling situation, which is convenient for the workers to carry out drilling operations.

[0011] 2. The height of the material receiving trough of this utility model is twice that of the mushroom-shaped aluminum. When the mushroom-shaped aluminum is placed in the material receiving trough, there is still a large amount of empty space, which can be used for collecting aluminum shavings, avoiding contamination around the construction platform. It is convenient to use and easy to operate. Attached Figure Description

[0016] The present invention will be further explained and described below with reference to the accompanying drawings:

[0017] See the example. Figures 1-3 A mushroom-shaped primary aluminum sampling and fixing device includes a receiving groove 1, which is distributed in a circular barrel shape. Three tightening bolts 2 are evenly arranged on the outer wall of the receiving groove 1. The tightening bolts 2 pass through the receiving groove 1 and are fixedly connected to the receiving groove 1 by threads. A handle 3 is provided on the outside of the receiving groove 1.

[0018] A mushroom-shaped primary aluminum 4 is placed in the receiving groove 1. The height of the receiving groove 1 is twice the height of the mushroom-shaped primary aluminum 4, and the inner diameter of the receiving groove 1 is greater than the outer diameter of the large opening of the mushroom-shaped primary aluminum 4.

[0019] The three tightening bolts 2 are distributed in an isosceles triangular shape in the cross-section of the receiving groove 1, and the tightening bolts 2 are located at the lower middle position of the outer wall of the receiving groove 1.

[0020] The receiving groove 1 is distributed with the upper port open and the lower port closed.

[0021] In the above description, the mushroom-shaped primary aluminum is distributed with a larger upper end and a smaller lower end, and the longitudinal cross-section of the mushroom-shaped primary aluminum is an isosceles trapezoid.

[0022] In the above description, when using the sample, place the mushroom-shaped aluminum sample in the receiving groove with the larger end facing upwards, and secure it with the tightening bolts on the outside of the receiving groove. Then, the operator holds the handle and places the mushroom-shaped aluminum sample under the drilling machine for sampling.

[0023] This invention fixes the sample in the receiving groove, which not only facilitates the drilling of aluminum shavings but also allows for free movement according to the drilling situation. At the same time, it prevents aluminum shavings from falling outside the receiving groove, making it easy to collect them uniformly. It is convenient to use, simple to operate, and easy to promote.
