[0029] This patent provides multiple parallel solutions; the different descriptions represent improved or parallel solutions based on a basic solution. Each solution has its own unique characteristics. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0030] Example 1: Referring to all the accompanying drawings; A device for efficiently detecting the symmetry of jet disk processing, characterized in that,

[0031] Connector 2 is connected to hydraulic test bench 1 and two pressure gauges 2011; cylindrical pin 3 is press-fitted into connector 2 with an interference fit; cylindrical pin 3 has corresponding pipelines for cylindrical pin return port 301 and cylindrical pin upper port 302.

[0032] The cylindrical pin 3 is fitted with the jet plate 4 and the sealing plate 6 under test with clearance.

[0033] The nut 7 presses down on the sealing plate 6, further tightening the jet plate 4 to be tested. The substantial technical effect and its implementation process, i.e., the basic function and non-obvious aspects, are as follows: This device for efficiently detecting the machining symmetry of the jet plate 4 can quickly and efficiently inspect and accept the machining quality of the jet plate 4.

[0034] This detection device mainly consists of a connector 2, a cylindrical pin 3, a sealing plate 6, and a nut 7. (See attached image) Figure 1 .

[0035] The connector 2 is connected to the hydraulic test bench 1 and is connected to the oil inlet and two pressure gauges of the hydraulic test bench 1 respectively; the cylindrical pin 3 is pressed into the connector 2 with an interference fit, and the cylindrical pin 3 is clearance fitted with the jet plate 4 and the sealing plate 6 to be tested; the nut 7 is pressed into the jet plate 4 to be tested to form a planar seal.

[0036] Equipment working principle: The jet plate 4 to be tested is installed on the connector 2, then the sealing plate 6 is installed, and finally the equipment is manually tightened with the nut 7. Then the hydraulic test bench 1 is turned on, and the working fluid is guided to the internal oil circuit of the jet plate 4 through the connector 2. After jetting, two pressure values ​​will be formed. The pressure is transmitted to the pressure gauge through the connector 2 to achieve rapid reading of the pressure value. The symmetry is judged by the difference in reading the pressure value.

[0037] Existing technology uses visual inspection to check symmetry, but this method has unclear criteria and poor accuracy.

[0038] This testing device can quickly and efficiently inspect and accept the symmetry of the jet plate 4 after it is used, and maintain the same state as the jet plate 4 in use, thus improving the testing accuracy.

[0039] After the cylindrical pin 3 is installed into the connector 2, the connector 2 is connected to the hydraulic test bench 1, connecting the oil inlet of the test bench 1 and two pressure gauges. When it is necessary to test the jet plate 4, the jet plate 4 and the sealing plate 6 are installed on the cylindrical pin 3 in sequence, and finally tightened with the nut 7. Then, the test bench 1 is turned on, and the values ​​of the two pressure gauges can be observed and recorded.

[0040] The connector 2, cylindrical pin 3, sealing plate 6, and nut 7 are made of high-strength stainless steel, and high requirements should be placed on their form and position tolerances.

[0041] The contact surfaces of the sealing sheet 6, the connector 2, and the test piece should have high surface roughness requirements.

[0042] The clearance between the cylindrical pin 3 and the jet plate 4 and the sealing plate 6 should not exceed 0.1mm.

[0043] The pipe connecting the pressure gauge to test bench 1 should be as short as possible.

[0044] Example 2: As a further improvement, parallel, or optional independent solution, the jet disk 4 to be tested is mounted on the cylindrical pin 3. The sealing structure 5 presses against the jet disk sealing opening 401 on the jet disk 4, and is then pressed down by the sealing plate 6 facing downwards, and then pressed down by the nut 7. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: similar sealing structures are all within the protection scope of this patent.

[0045] Example 3: As a further improvement, parallel solution, or optional independent solution, the connector 2, cylindrical pin 3, sealing plate 6, and nut 7 are made of high-strength stainless steel. The substantial technical effects and implementation process, i.e., the basic functions and non-obvious aspects, are as follows: similar materials are all within the scope of protection of this patent.

[0046] Example 4: As a further improvement, parallel solution, or optional independent solution, the clearance between the cylindrical pin 3 and the jet disk 4 and sealing plate 6 is no greater than 0.1mm. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: similar clearances are also within the scope of protection of this patent.

[0047] Example 5: As a further possible improvement, parallel solution, or optional independent solution, the connector 2 is connected to the hydraulic test bench 1 in such a way that the test bench return oil pipe 101 and the test bench upper oil pipe 102 in the hydraulic test bench 1 correspond to the connector return oil pipe 201 and the connector upper oil pipe 202 of the connector 2, respectively; the connector return oil pipe 201 and the connector upper oil pipe 202 correspond to the pipelines corresponding to the cylindrical pin return oil port 301 and the cylindrical pin upper oil port 302, respectively. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: it provides a specific oil circuit connection, and similar implementation structures are all within the protection scope of this patent.

[0048] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0049] It should be noted that the multiple modules in this patent are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, those programs are undoubtedly known programs.

[0050] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
