Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production technology, specifically to an auxiliary device for drilling component samples from small aluminum alloy test blocks. Background Technology

[0002] In the research, development, production, and quality testing of aluminum alloy materials, compositional analysis is a crucial step in ensuring product quality and performance. Accurate compositional analysis provides key information for performance optimization, quality control, and new product development of aluminum alloys. However, many problems are currently encountered when drilling compositional samples from small aluminum alloy test blocks. Chemical analysis samples from aluminum alloy melts are often made from mold-cast round test blocks. When analyzing a specific part of an ingot or finished product, a square test block is usually cut, and the sample is then drilled from it. However, collecting the required fragments during the actual drilling process is a challenge, and the fragments are prone to splashing during drilling, potentially leading to sample loss and affecting the accuracy and representativeness of the analysis results. Currently, most methods involve placing paper under the test block. During drilling, the operator gently holds the front end of the paper to create a barrier, minimizing fragment splashing. The drilled sample is then collected on the paper and transferred to a sample bag. However, this temporary method has serious drawbacks. On the one hand, the paper is fragile and easily damaged during the clamping process. Once the paper is damaged, it is impossible to continue to collect fragment samples effectively, resulting in the interruption of the collection work. Even when the paper is intact, a large number of fragment samples will splash out of the paper, and the representativeness of the sample cannot be effectively guaranteed. On the other hand, manual operation poses great safety hazards. During the drilling process, the drill bit rotates at high speed. When the operator holds the paper, his / her hand is close to the drill bit. If he / she is not careful, he / she may be injured by the drill bit, causing a serious safety accident and posing a direct threat to the personal safety of the operator. Utility Model Content

[0003] This invention provides an auxiliary device for drilling component samples from small aluminum alloy test blocks to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary device for drilling component samples of aluminum alloy micro-sample blocks includes a sample sleeve, with lining plates symmetrically and movably provided on the bottom of the inner wall of the sample sleeve, and clamping blocks horizontally and movably passing through the inner wall of the sample sleeve corresponding to the bottom of the lining plates, and the clamping blocks are all connected to the drill press vise.

[0006] Furthermore, the bottom of the inner wall of the sample sleeve is symmetrically fixed with a liner sleeve, and the liner and the liner sleeve are movably connected.

[0007] Furthermore, clamping holes are provided on the inner wall of the sample sleeve corresponding to the bottom of the liner, and the clamping blocks are all installed through the clamping holes.

[0008] Furthermore, each of the clamping blocks has anti-slip teeth at one end that extends into the inner side of the sample sleeve.

[0009] This utility model has the following beneficial effects:

[0010] This invention features simple manufacturing, convenient operation, and strong practicality. The device is designed with a sample sleeve in which the sample block to be drilled is placed.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 As shown, an auxiliary device for drilling component samples of aluminum alloy micro-sample blocks includes a sample sleeve 1. The bottom of the inner wall of the sample sleeve 1 is symmetrically provided with a liner 3. The bottom of the liner 3 is provided with a horizontally movable clamping block 6 at the corresponding inner wall of the sample sleeve 1, and the clamping blocks 6 are all connected to the drill press vise 8.

[0016] The bottom of the inner wall of the sample sleeve 1 is symmetrically fixed with a liner sleeve 4, and the liner 3 and the liner sleeve 4 are movably connected.

[0017] Clamping holes 5 are provided on the inner wall of the sample sleeve 1 corresponding to the bottom of the liner 3, and the clamping blocks 6 are all set through the clamping holes 5.

[0018] The end of the clamping block 6 that extends into the inner side of the sample sleeve 1 is provided with anti-slip teeth 7.

[0019] The aluminum alloy molten sample is taken as a round disc specimen, 10mm thick and 70mm in diameter. The device mainly consists of a sample sleeve 1 and a movable clamping block 6 penetrating the sample sleeve 1. The sample sleeve 1 is cylindrical, 100mm high, and 90mm in diameter, made of steel. The top of the sample sleeve 1 is open and hollow, while the bottom is flat and sealed. Two clamping block holes 5 are symmetrically opened against the bottom cylindrical wall, each measuring 32mm x 22mm. Each clamping block hole 5 has one clamping block that is tightly attached to the sample sleeve. The liner 3 on the side wall is used for blocking. The liner 3 is fixed by the liner sleeve 4 fixed on the side wall of the sample sleeve 1. The liner 3 can slide up and down along the cylinder wall. When it slides up, the clamping block hole 5 opens. After it is released, it falls down to block the clamping block hole 5. The clamping block 6 is made of cast iron and is rectangular in shape with a length * width * height of 50mm * 30mm * 20mm. It is embedded into the cylinder from both sides of the outer side wall of the sample sleeve 1. One end of the cylinder is clamped on the bench vise 8, and the other end of the cylinder is clamped on the sample 2. It has anti-slip teeth 7, which play a role in firmly fixing the sample 2.

[0020] In practical application, the circular test block with the surface oxide layer removed is placed at the bottom center of the sample sleeve 1. The liner 3 is slid upward to open the clamping hole 5. One end of the clamping block 6 with anti-slip teeth 7 is inserted into the clamping hole 5. Both clamping blocks 6 are inserted into the clamping hole 5, ensuring that the sample 2 is centered in the sample sleeve 1 and that the lengths of the two clamping blocks 6 are similar inside the sample sleeve 1. This device is then placed in the jaws of the bench vise 8, with one side close to the jaws, ensuring that the sample 2 is not obstructed when clamped in the sample sleeve 1. If a large displacement occurs, clamp the vise 8 again. The force of the vise 8 causes the clamping block 6 to clamp the sample 2. Then, use a drill press to drill the sample 2. Most of the sample debris 2 accumulates inside the sample sleeve 1. After drilling, release the vise 8, first pull out one side of the clamping block 6, and the liner 3 on the same side falls down to block the clamping block hole 5. Then pull out the other side of the clamping block 6, and the liner 3 on the other side falls down to block the clamping block hole 5. The required sample debris 2 remains inside the sample sleeve 1. The sample sleeve 1 forms a beaker-shaped container, which can also be used directly for sample transfer. The entire drilling process of the sample 2 effectively improves the collection efficiency and ease of operation of the sample 2. Therefore, this device has good practicality.
