[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the cylinder crushing fixture proposed in this utility model includes a lower positioning plate 1, a fixed protective structure 2, and a pressureless limiting fixing structure 3. The fixed protective structure 2 is disposed on the lower positioning plate 1, and the pressureless limiting fixing structure 3 is disposed on the lower positioning plate 1. The fixed protective structure 2 includes a side plate 4, a first fixing bolt 5, an upper positioning plate 6, and a second fixing bolt 7. The side plate 4 is detachably disposed on the lower positioning plate 1. The first fixing bolt 5 passes through the lower positioning plate 1 and is threaded at the bottom of the side plate 4. The upper positioning plate 6 is detachably disposed above the side plate 4. The side plate 4 is supported between the lower positioning plate 1 and the upper positioning plate 6 to form a protective space. The second fixing bolt 7 passes through the upper positioning plate 6 and is threaded at the top of the side plate 4.
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the pressureless limiting and fixing structure 3 includes a positioning pin 1 8, a positioning pin 2 9, and a pressure pin 10. The positioning pin 1 8 is inserted into the upper limit hole of the lower positioning plate 1, and the positioning pin 2 9 is inserted into the upper limit hole of the lower positioning plate 1. The upper part of the positioning pin 2 9 is semi-circular, and the lower part is provided with two sets of pins. The positioning pin 1 8 fixes the outside of the product, and the positioning pin 2 9 fixes the inside of the product. The pressure pin 10 passes through the upper positioning plate 6 and is provided as a compression support above the lower positioning plate 1. The upper end of the pressure pin 10 is cylindrical, but the lower end is flat and the thickness gradually increases towards the rear.
[0022] In practical use, when using this device, the user first fixes the lower positioning plate 1 and the side plate 4 with the threaded connection of the side plate 4. Then, install the positioning pin 1 8 and the positioning pin 2 9 into the positioning holes on the lower positioning plate 1. Place the product on the lower positioning plate 1 and fix the product with the positioning pin 1 8 and the positioning pin 2 9, i.e., fix the straight groove position of the product test. Then, cover the side plate 4 with the upper positioning plate 6 and fix it with the threaded connection of the fixing bolt 2 7. Then, insert the pressure pin 10 through the upper limit hole of the upper positioning plate 6 and insert the narrow end of the pressure pin 10 into the straight groove position of the product. Slightly rotate the pressure pin 10 to confirm that the position is accurate. After confirming that the position is correct, place the fixture on the crushing machine and start the test. Record the pressure applied by the crushing machine when the product is crushed. This completes one crushing test of the product. Then, conduct multiple tests, statistically analyze and calculate the data to obtain the maximum support force that the product can withstand. The above is the entire process of using the cylinder crushing fixture.
