Description

Technical Field

[0001] The utility model relates to the technical field of seal leakage simulation detection, in particular to a mechanical device simulation tool. Background Art

[0002] A mechanical device refers to a device that transmits power and motion through mechanical elements. Leakage simulation detection is a test method used to determine whether a sealed container has a leak. Common leak detection methods include pressure drop method, acoustic emission technology, drainage method and bubble method. Leakage detection through a mechanical device is also a detection method, and a simulation test bench is a very common auxiliary equipment in leak simulation detection.

[0003] During the process of gas leakage simulation detection, when it is necessary to use a simulation detection table for assistance, the base is first moved to the designated location, and then the gas is introduced into the test cabinet through the air inlet pipe, and then the gas is introduced into the gas observation box through the test cabinet. After that, the gas flow diffusion trajectory is obtained by the optical sensor, and the signal is transmitted to the computer for analysis and calculation, so as to achieve the purpose of judging the leakage amount and leakage degree. After the simulation is completed, the air is exhausted through the air outlet, so as to complete the leakage simulation detection through the mechanical device; however, during the use of the simulation detection table, the staff will be replaced. At this time, due to the different heights and usage habits of the staff, it is often necessary to adjust the height of the simulation detection table to match the height of the staff. However, in order to prevent the simulation detection table from moving at will, its bottom is usually fixed on the ground, and most of the simulation detection tables are fixed structures, which makes it more complicated for people to adjust the height of the simulation detection table, and then people can only endure working on the simulation detection table that does not match their height, which affects the staff's experience and thus affects the use of simulation tools.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: a mechanical device simulation tool, including a workbench 1, a test cabinet 2 and a gas observation box 4, the top side of the workbench 1 is connected to the test cabinet 2, and the outer wall side of the test cabinet 2 is connected to the air inlet pipe 3, the side of the test cabinet 2 away from the air inlet pipe 3 is connected to the gas observation box 4, and the middle part of the outer wall of the gas observation box 4 is connected to an air outlet 5, and the side of the gas observation box 4 away from the test cabinet 2 is connected to a cover plate 6, and the middle part of the outer wall of the cover plate 6 is installed with an optical sensor 7, the inner wall of the workbench 1 is slidably connected to a base 8, and an adjustment mechanism 9 is arranged inside the base 8, and the adjustment mechanism 9 includes a support seat 91, a motor 92, a guide column A93, a gear A94, a gear B95, a guide column B96, a guide rod A97 and a guide rod B98, the bottom end of the inner wall of the base 8 A support seat 91 is welded, and the outer wall of the support seat 91 is connected to the motor 92 by screws; a guide column A93 is connected to the output end of the motor 92, and a gear A94 is sleeved on the outer wall of the guide column A93 away from the motor 92; a gear B95 is meshingly connected to the outer wall of the gear A94, and a guide column B96 is connected inside the gear B95; a guide rod A97 is sleeved on the middle part of the outer wall of the guide column B96 and the guide column A93, and a guide rod B98 is rotatably connected to the top of the guide rod A97; the top of the guide rod B98 is connected to the workbench 1 through a fixed seat, and a limit cavity that is connected to the workbench 1 is opened on the outer wall of the base 8; the guide rod B98 is rotatably connected to the workbench 1, the guide column B96 is rotatably connected to the support seat 91, and the guide column B96 and the guide column A93 are parallel to each other.

[0024] In the specific implementation, during the gas leakage simulation detection, when the simulation detection table is used for assistance, in order to make the height of the workbench 1 conform to people's usage habits, when it needs to be adjusted, the motor 92 on the support seat 91 is first started. Since the output end of the motor 92 is connected to the guide column A93, the motor 92 is started to drive the guide column A93 to rotate, and then the guide column A93 rotates to drive the gear A94 to rotate. Since the gear A94 is meshed with the gear B95, the gear A94 rotates to drive the gear B95 to rotate;

[0025] Then the gear B95 rotates to drive the guide post B96 to rotate, and because the guide post B96 and the guide post A93 are both connected to the guide rod A97, the guide posts A93 and B96 rotate to drive the guide rod A97 to rotate. Because the guide rod A97 and the guide rod B98 are rotationally connected, the guide rod A97 rotates the guide rod B98 to rotate, and at this time the angle between the guide rod A97 and the guide rod B98 changes;

[0026] This then squeezes the workbench 1, causing it to move upward along the base 8 until the components on the workbench 1 reach a specified height, and then automatically adjusts the height of the workbench 1 to match the height and usage habits of people without the need for people to adjust it manually and laboriously, thereby facilitating adjustment when the mechanical device simulates the use of tools.

[0027] See also Figure 1 , Figure 2 and Figure 5 It can be seen that an auxiliary mechanism 10 is arranged on the outer wall of the cover plate 6, and the auxiliary mechanism 10 includes a limit seat 101, a positioning pin 102, a rotating seat 103, a fixing part 104, a clamping strip 105 and a sealing gasket 106. The limit seat 101 is welded on the upper and lower sides of the gas observation box 4; the limit seat 101 is connected with the positioning pin 102 through the limit hole, the rotating seat 103 is docked on the upper and lower sides of the cover plate 6, and the fixing part 104 is connected inside the rotating seat 103; the fixing part 104 is connected with the clamping strip 105 through the clamping groove, and the outer wall of the cover plate 6 is connected with the sealing gasket 106 through the sealing groove; the positioning pin 102 is fixedly connected to the cover plate 6, the clamping strip 105 is clamped to the limit seat 101, and a clamping groove docking with the clamping strip 105 is provided inside the fixing part 104.

[0028] In the specific implementation, during the gas leakage simulation detection, when the simulation detection table is used for assistance, as the use time increases, when the inner wall of the gas observation box 4 is adhered with dirt and needs to be cleaned, the clamping strip 105 is manually moved first, so that the clamping strip 105 is disengaged from the clamping connection with the fixing member 104 and the limiting seat 101, and then the limiting of the fixing member 104 is cancelled. Since the fixing member 104 is connected to the rotating seat 103, the fixing member 104 is then rotated so that the fixing member 104 leaves the vicinity of the limiting seat 101, and then the cover plate 6 is moved horizontally;

[0029] The cover plate 6 is separated from the gas observation box 4, and then the inside of the gas observation box 4 is exposed. At this time, the inside of the gas observation box 4 is cleaned, and the inside of the gas observation box 4 can be cleaned without removing the gas observation box 4 from the workbench 1 or disassembling the gas observation box 4 on a large scale, thereby facilitating cleaning when the mechanical device simulates the use of the tool;

[0030] When the interior of the gas observation box 4 is cleaned, the cover 6 is first docked with the gas observation box 4. Since the cover 6 is connected to the positioning pin 102, the positioning pin 102 is now docked with the limit seat 101, thereby limiting the cover 6 to prevent the cover 6 from moving at will. At this time, the cover 6 squeezes the sealing gasket 106, thereby preventing gas from leaking from the connection between the cover 6 and the gas observation box 4 through the sealing gasket 106. Then, the fixing part 104 is rotated close to the limiting seat 101, and then the snap-in strip 105 is moved to dock with the limiting seat 101 and the fixing part 104. At this time, the snap-in strip 105 is in a snap-fit ​​connection with the limiting seat 101 and the fixing part 104, and then the cover 6 is fixed. Then, there is no need to repeatedly rotate multiple sets of bolts to fix the cover 6 on the gas observation box 4.

[0031] To sum up, when this mechanical device simulation tool is used, the base 8 is first moved to the designated location, and then the gas is introduced into the experimental cabinet 2 through the air inlet pipe 3, and then the gas is introduced into the gas observation box 4 through the experimental cabinet 2. After that, the gas flow diffusion trajectory is obtained by the optical sensor 7, and then the signal is transmitted to the computer for analysis and calculation, so as to achieve the purpose of judging the leakage amount and leakage degree. After the simulation is completed, the air is exhausted through the air outlet pipe 5, so that the leakage simulation detection is completed by the mechanical device. This is the prior art and will not be elaborated on here. The height of the workbench 1 is automatically adjusted by the adjustment mechanism 9, so that the height of the workbench 1 corresponds to people's height and usage habits, and people do not need to adjust it manually and laboriously. The auxiliary mechanism 10 makes the inside of the gas observation box 4 visible for cleaning, and there is no need to remove the gas observation box 4 from the workbench 1, and to disassemble the gas observation box 4 on a large scale, and the inside of the gas observation box 4 can be cleaned. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
