[0044] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0045] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0046] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0047] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 6 illustrate.

[0048] This application provides a rotary vane vacuum pump testing device, which is used to perform factory testing on rotary vane vacuum pumps, thereby testing the function of the rotary vane vacuum pumps and verifying whether they can operate normally.

[0049] like Figure 1 As shown, the rotary vane vacuum pump testing device (hereinafter referred to as the testing device) includes a transfer mechanism 2, a testing mechanism 1, and an oil supply mechanism 3. The transfer mechanism 2 is provided with an assembly area 241 and a testing area 243. The assembly area 241 provides a space for workers to assemble the test product (rotary vane vacuum pump) onto the transfer mechanism 2. The testing mechanism 1 is located in the testing area 243 to test the test product. The test product can be transferred from the assembly area 241 to the testing area 243 through the transfer mechanism 2, saving labor and improving testing efficiency. The oil supply mechanism 3 is used to add oil to the test product to assist the testing mechanism 1 in testing. The oil supply mechanism 3 can also recover the oil poured out after testing, allowing the oil to be recycled and conserved resources.

[0050] Specifically, the transmission mechanism 2 will be further described; such as Figure 1As shown, the transmission mechanism 2 also includes a transmission area 242, which has a C-shaped structure. The assembly area 241 and the testing area 243 have straight-line structures. The assembly area 241 and the testing area 243 are arranged parallel to each other at both ends of the transmission area 242, so that the transmission mechanism 2 forms a U-shaped structure. This results in high integration of the testing device and a small footprint, which is more conducive to saving space costs. There is a gap between the assembly area 241 and the testing area 243, which provides space for workers to stand and pass through, so that workers can operate the test products on the transmission area 242, the assembly area 241, and the testing area 243.

[0051] In this embodiment, the transfer area 242 is located between the assembly area 241 and the testing area 243. The products to be tested assembled in the assembly area 241 can be transferred to the testing area 243 via the transfer area 242. The transfer area 242 serves as a buffer and temporary storage area, enabling the testing area 243 to test multiple products simultaneously. Furthermore, in this application, the testing area 243 is equipped with multiple testing stations, increasing the number of tests and testing efficiency while saving testing costs. These multiple testing stations can operate simultaneously or individually, improving the flexibility of the testing device.

[0052] Furthermore, such as Figure 1 As shown, the transfer mechanism 2 includes a tooling plate 23, a support base 21, and a roller assembly 22. The support base 21 includes support legs and a transfer track 24. The support legs are located at the bottom of the transfer track 24 and are used to raise and support the transfer track 24. The transfer track 24 has a U-shaped structure, and its extension direction is the direction of transport and movement of the test product. The roller assembly 22 is rotatably mounted on the upper surface of the transfer track 24. The tooling plate 23 is mounted on the transfer track 24, and its bottom is in contact with the upper surface of the roller assembly 22. The tooling plate 23 can slide relative to the roller assembly 22, thereby allowing the tooling plate 23 to move on the transfer track 24. The upper end of the tooling plate 23 is connected to the test product, and the tooling plate 23 can carry the test product to move along the transfer track 24 to achieve the displacement of the test product from the assembly area 241 to the transfer area 242, and then from the transfer area 242 to the test area 243, while ensuring the continuity of assembly and testing.

[0053] like Figure 1 , Figure 5 As shown, the transmission track 24 includes two ends, and the distance between the two ends is greater than the length of the tooling plate 23 so that the tooling plate 23 can pass smoothly through the transmission area 242. The transmission track 24 is provided with limiting baffles 25 on both sides, which extend upward and are used to limit the side ends of the tooling plate 23 to confine the tooling plate 23 within the transmission track 24 and prevent it from easily coming off the two ends of the transmission track 24.

[0054] Among them, such as Figure 4 , Figure 5 As shown, the tooling plate 23 is provided with a heightening block. The test product is connected to the tooling plate 23 through the heightening block. The length and width of the heightening block are both smaller than those of the tooling plate 23. The heightening block extends upward, and the height of the top surface of the heightening block exceeds the height of the limiting baffle 25. This ensures that when the test product is installed on the heightening block, the bottom of the test product extends beyond the transmission track 24 and the limiting baffle 25, thus preventing the bottom of the test product from interfering with the limiting baffle 25 or the transmission track 24 when the test product moves.

[0055] Furthermore, the transmission mechanism 2 can be further expanded; for example... Figure 1 , Figure 3 , Figure 5 As shown, the assembly area 241 and the test area 243 are provided with mounting rails 26 for mounting the roller assembly 22. The bottom of the mounting rails 26 is fixedly connected to the transmission track 24, and the roller assembly 22 is rotatably connected to the mounting rails 26. The mounting rails 26 are arranged on opposite sides of the transmission track 24. The mounting rails 26 are straight structures, and the two mounting rails 26 are arranged in parallel and spaced apart. The distance between the two mounting rails 26 is less than the length of the tooling plate 23.

[0056] In this embodiment, such as Figure 3 As shown, the roller assembly 22 includes a friction roller 221 and a ball bearing 222. The friction roller 221 is disposed within the mounting rail 26 and has a cylindrical structure. Connecting shafts are provided at both ends of the central axis of the friction roller 221, and the connecting shafts protrude outward from the mounting rail 26 for rotatable connection. The cross-section of the mounting rail 26 is an inverted n-shaped rectangular structure to form a mounting groove for accommodating the friction roller 221, and the friction roller 221 is disposed within the mounting groove. In this embodiment, multiple friction rollers 221 are provided, and the multiple friction rollers 221 are equidistantly spaced along the length direction of the mounting rail 26. The friction rollers 221 serve as an intermediate medium, so that the tooling plate 23 carrying the test product can be moved more easily within the assembly area 241 and the test area 243 with only a small force, saving labor and improving work efficiency.

[0057] like Figure 3 As shown, the ball bearing 222 is disposed in the transmission area 242, and the transmission area 242 is provided with a fixed seat. The bottom of the fixed seat is fixedly connected to the transmission track 24 of the transmission area 242. The ball bearing 222 is rotatably disposed in the fixed seat, that is, the ball bearing 222 can roll relative to the fixed seat. The upper end surface of the ball bearing 222 protrudes from the upper end surface of the fixed seat, so that the bottom of the tooling plate 23 can directly contact the upper end surface of the ball bearing 222. The ball bearing 222 serves as an intermediate medium, so that the tooling plate 23 carrying the test product can slide more easily in the transmission area 242 with only a small force, saving labor and improving work efficiency.

[0058] Among them, such as Figure 1As shown, the transmission zone 242 includes an inner support portion 2421 and an outer support portion 2422. Both the inner support portion 2421 and the outer support portion 2422 are semi-circular structures. The outer support portion 2422 is arranged around the outside of the inner support portion 2421. There is a gap between the inner support portion 2421 and the outer support portion 2422 to save materials. The balls 222 are arranged at intervals along the same circumference on the inner support portion 2421 and the outer support portion 2422, and are arranged in the same radial direction. Multiple balls 222 are provided on the inner support portion 2421 and the outer support portion 2422, and the balls 222 on the inner support portion 2421 and the outer support portion 2422 are arranged at intervals along the same radial direction to ensure that the balls 222 on the transmission zone 242 have a more uniform and regular effect on the tooling plate 23.

[0059] Based on any of the above embodiments, the testing mechanism 1 can be further expanded; such as... Figure 1 , Figure 2 , Figure 4 As shown, the test mechanism 1 includes a mounting bracket 13, an oil pouring assembly 12, and a power assembly 11. The mounting bracket 13 is connected to the outer frame of the transmission track 24 of the test area 243. The mounting bracket 13 is located on the side of the test area 243 away from the assembly area 241, and extends upwards beyond the upper surface of the transmission mechanism 2. Figure 4 As shown, the power assembly 11 is mounted on the mounting bracket 13 and located above the test product. The power assembly 11 includes a power source and a power connector. The power connector is a socket and is mounted on the mounting bracket 13. The power socket and the power source are connected by a wire. The power source is a power supply. When the test product is tested, it is connected to the power connector through the power cord to obtain power, so that the rotary vane vacuum pump can be powered on for testing to determine whether it is qualified.

[0060] like Figure 4 As shown, the oil pouring component 12 is positioned between the mounting rail 26 in the test area 243 that is away from the assembly area 241 and the mounting rail 26 that is close to the assembly area 241. The oil pouring component 12 is located below the rear end of the test product. The oil pouring component 12 can move up and down to apply a force to the rear end of the test product, raising the rear end of the test product so that the oil in the test product can be poured out. Alternatively, after pouring the oil, the oil pouring component 12 can move down to make the test product parallel, making it easier for staff to remove the tested product.

[0061] It should be noted that, in this embodiment, the oil pouring component 12 is located at the opposite end of the oil outlet of the test product. That is, if the oil outlet is located at the front end of the test product, the oil pouring component 12 is located at the rear end of the test product; if the oil outlet is located at the rear end of the test product, the oil pouring component 12 is located at the front end of the test product.

[0062] Specifically, such as Figure 4As shown, the oil pouring assembly 12 includes a top plate 121 and a drive member 122. The side end of the drive member 122 is fixedly connected to the side end of the mounting rail 26, and the bottom of the top plate 121 is fixedly connected to the drive end of the drive member 122. The drive end of the drive member 122 can move vertically. The top plate 121 is located at the lower end of the test product. The drive member 122 can drive the top plate 121 to move up and down, so that the top plate 121 can push the rear end of the test product to lift or lower, so that the test product can be tilted. The oil in the test product can be poured out from the front oil outlet to realize automatic oil pouring. There is no need for manual lifting of the vacuum pump to pour oil, which can save labor and improve work efficiency.

[0063] In this embodiment, the driving component 122 is a cylinder, and the upper end of the top plate 121 has an arc-shaped structure so that when the top plate 121 lifts the test product, the bottom of the test product can still fit with the top plate 121, ensuring the support stability of the top plate 121 for the test product at any tilt angle.

[0064] Furthermore, the testing mechanism 1 also includes a control button 14, which is located on the side of the transmission track 24 near the assembly area 241 in the testing area 243. The control button 14 is connected to the power source and the oil pouring assembly 12, and can control the start and stop of the power assembly 11 and the oil pouring assembly 12.

[0065] Specifically, such as Figure 4 As shown, the control button 14 includes a main switch and branch switches. The main switch is connected to the branch switches. The main switch is located at one end near the oil supply mechanism 3. There is one main switch and multiple branch switches. Each test station corresponds to one branch switch, one oil pouring component 12, and one power component 11. The main switch is used to control the power supply of the entire test mechanism 1 and the power supply of all oil pouring components 12 during the entire test. The branch switches are used to control the power supply of each test station.

[0066] In addition, the main switch is equipped with a button to control the start and stop of the oil pouring component 12, a button to control single-phase power, and a button to control two-phase power; the branch switches are equipped with a button to control the start of a single test station and a fault alarm button; in addition, an oil supply mechanism 3 oil inlet button can be set on the branch switches or the main switch so that the oil supply mechanism 3 can realize automatic oil supply to the test product.

[0067] Based on any of the above embodiments, the oil supply mechanism 3 will be further described; such as Figure 1 , Figure 2As shown, the oil supply mechanism 3 includes an oil storage component 31, an oil inlet component, and an oil return component. The oil storage component 31 is used to store oil. In this embodiment, the oil storage component 31 is a square oil tank. The oil inlet component and the oil return component are both connected to the oil storage component 31. The oil inlet component is used to guide the oil in the oil storage component 31 to the product to be tested, and the oil return component is used to guide the oil poured out of the product to be tested back to the oil storage component 31, so as to realize the automatic oil filling and emptying of the automatic test product, save manual operation requirements, and improve work efficiency.

[0068] Among them, such as Figure 2 , Figure 6 As shown, the oil supply mechanism 3 also includes a filter assembly 33, and the oil return assembly includes an oil collector 32 and an oil guide pipe. The oil collector 32 is located at the oil outlet end of the product under test and is used to collect the oil poured out of the product under test. The oil guide pipe is used to guide the oil in the oil collector 32 to the oil storage unit 31. The oil collector 32 has a rectangular structure and an opening at the upper end, which is located below the oil outlet of the vacuum pump. The oil collector 32 can collect the oil poured out of the test products at all test stations on the test mechanism 1. The oil collection component 32 has an outlet at its bottom, which is connected to the filter component 33. The oil collection component 32 collects the oil poured out by the test product, and the oil collected in the oil collection component 32 flows to the filter component 33. The filter component 33 is located between the oil return component and the oil storage component 31. The filter component 33 is used to filter the oil flowing out of the oil collection component 32, and to filter out the residue and debris carried out by the test product, so that the oil returning to the oil storage component 31 is clean and can be recycled.

[0069] It should be noted that, in this embodiment, the oil storage component 31 is equipped with an oil pump, which can realize oil return absorption and oil inlet drive, so as to automatically realize oil return and oil inlet.

[0070] Furthermore, such as Figure 6 As shown, the oil collecting component 32 is provided with an oil guide plate 321. The oil guide plate 321 is located at one end of the oil collecting component 32 close to the test product. The oil guide plate 321 is inclined towards the test product and is inclined to the lower end of the oil outlet of the test product, and is located inside the oil inlet, so that the oil in the oil inlet can flow into the oil collecting component 32 as much as possible.

[0071] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.
