It is widely used in the industrial manufacturing field, especially for products that need to ensure no leakage or rupture under high-pressure environments, such as pressure vessels, pipelines, valves, etc.

[0003] When the existing high-pressure pressing machine is in use, if the position of the workpiece is not accurately positioned, then under the action of high pressure, the workpiece may undergo slight movement or deviation, resulting in inaccurate processing dimensions, thereby affecting the overall quality and performance of the product. The lack of precise positioning may lead to the need for operators to frequently adjust the position of the workpiece. Therefore, it is necessary to provide a device that can fix the position of the workpiece and improve the production quality. Content of the Utility Model

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0030] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figures 1 to 5 as shown. This embodiment is a high-pressure airtight pressure tester, including:

[0032] A pressure tester body 11 and a mounting plate 13. The mounting plate 13 is located inside the pressure tester body 11. A first cylinder 12 is fixed on the upper surface of the mounting plate 13. Support rods 131 are fixed at the four corners of the lower surface of the mounting plate 13. A placement mold 15 is fixed on one side below the mounting plate 13, and a second cylinder 14 is fixed on one side of the placement mold 15.

[0033] A positioning assembly. The positioning assembly includes a limit frame 24, a lead screw 25, a positive thread groove 251, a reverse thread groove 252, a first positioning block 26, and a second positioning block 27. The limit frame 24 is fixed on the lower surface of the mounting plate 13. The lead screw 25 penetrates through the middle of the limit frame 24. The positive thread groove 251 is opened on one side of the lead screw 25, and the reverse thread groove 252 is opened on the other side of the lead screw 25. The first positioning block 26 is threadedly penetrated through one side of the lead screw 25, and the second positioning block 27 is threadedly penetrated through the other side of the lead screw 25;

[0034] The limit frame 24 is used to limit the movement range of the lead screw 25 to ensure that the lead screw 25 does not exceed the predetermined position during rotation. The lead screw 25 rotates to drive other structures. In the positioning assembly, the rotation of the lead screw 25 will drive the relative movement of the positive thread groove 251 and the reverse thread groove 252, thereby realizing the precise positioning of the workpiece. The second positioning block 27 and the first positioning block 26 work together to provide additional support and stability to ensure that the workpiece maintains an accurate position during processing.

[0035] The positioning assembly further includes a motor 21, a support table 211, and a first gear 22. The motor 21 is located on one side of the mounting plate 13. The support table 211 is fixed on the outer surface of the motor 21, and the upper surface of the support table 211 is fixed on the lower surface of the mounting plate 13. The first gear 22 is fixed on the output end of the motor 21. A second gear 23 is fixedly penetrated through the inside of the limit frame 24, and the second gear 23 is engaged on the outer surface side of the first gear 22. The center of the second gear 23 is fixedly penetrated through the middle of the lead screw 25;

[0036] The motor 21 drives the relative movement of the positive thread groove 251 and the reverse thread groove 252 by rotating the lead screw 25, thereby realizing the precise positioning of the workpiece. The performance of the motor 21 directly affects the accuracy and efficiency of the positioning component. The first gear 22 is used to transmit the power of the motor 21 to the lead screw 25. The first gear 22 meshes with the second gear 23 and drives the lead screw 25 by rotation. The second gear 23 receives the power from the first gear 22 and transmits it to the lead screw 25, thereby driving the lead screw to rotate.

[0037] Working principle:

[0038] When the workpiece is placed on the placement mold 15, at this time, the staff uses an external controller to start the motor 21. The motor 21 starts and synchronously drives the first gear 22. The first gear 22 rotates to drive the meshed second gear 23 to rotate. The second gear 23 rotates to drive the lead screw 25 to rotate. The lead screw 25 rotates to drive the relative rotation of the positive thread groove 251 and the reverse thread groove 252. The relative rotation of the positive thread groove 251 and the reverse thread groove 252 causes the relative movement of the first positioning block 26 and the second positioning block 27, and positions the workpiece at the center of the placement mold 15.

[0039] In this step, through an accurate positioning mechanism, it is ensured that the position of the workpiece is stable during the processing, reducing the processing errors caused by position deviation, thereby improving the processing accuracy of the product.

[0040] Please refer to Figures 1 to 5 as shown; based on the above-mentioned Embodiment 1, this embodiment further includes:

[0041] An installation component, which includes an installation groove 31, a fixing hole 32, a rubber block 33, and an installation hole 34. The installation groove 31 is opened on one side of the first positioning block 26 and the second positioning block 27. The fixing holes 32 are opened on both sides of the installation groove 31, and the installation groove 31 communicates with the fixing holes 32. The rubber block 33 is installed inside the installation groove 31. The installation holes 34 are opened on both sides of the rubber block 33. A spring 35 is fixed inside the installation hole 34. One end of the spring 35 is fixed with a fixing column 36, and the outer end of the fixing column 36 extends into the fixing hole 32.

[0042] The installation groove 31 is used to accommodate the rubber block 33 to ensure that the workpiece can be accurately positioned during the processing. The spring 35 is fixed inside the installation hole 34. The function of the hole is to accommodate the spring 35 and the fixing column 36, so that the rubber block 33 can be firmly fixed on the positioning block. One end of the spring 35 is fixed with a fixing column 36. The function of the spring 35 is to provide elastic force when the fixing column 36 moves, so that the fixing column 36 can move inside the installation hole 34 and finally be fixed inside the fixing hole 32.

[0043] Working principle:

[0044] When the first positioning block 26 and the second positioning block 27 position the workpiece from both sides, the staff installs the rubber block 33 into the installation groove 31 of the first positioning block 26 and the second positioning block 27. The staff presses the fixing column 36 inward, compressing the spring 35 in the installation hole 34 and moving the fixing column 36 into the installation hole 34. Then, the rubber block 33 is installed into the installation groove 31. When the installation hole 34 and the fixing hole 32 are directly corresponding, under the elastic force of the spring 35, the spring 35 will quickly recover its deformation, causing the end of the fixing column 36 to extend into the interior of the fixing hole 32, fixing the rubber block 33 in the first positioning block 26 for easy replacement;

[0045] In this step, the rubber block 33 can be customized according to the specific shape of the workpiece and is applicable to workpieces of various different shapes and sizes, having strong versatility and flexibility.

[0046] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium; it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
