Description

Technical Field

[0001] This utility model relates to the field of molecular pump assisted assembly and disassembly technology, specifically to a molecular pump assisted assembly and disassembly device. Background Technology

[0002] A molecular pump is a vacuum pump that uses a high-speed rotating rotor to transfer momentum to gas molecules, giving them a directional velocity, thereby compressing them and driving them toward the exhaust port to be pumped away by the forestage. The two common installation methods for molecular pumps are side mounting below the machine chamber and inverted mounting above the machine chamber.

[0003] When assembling or disassembling traditional molecular pumps, due to the pump's heavy weight, personnel need to manually adjust the pump's angle after it is placed on the assembly / disassembly table. This is both labor-intensive and inaccurate. Although the angle can be adjusted by moving around the pump itself, this greatly increases the workload for personnel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an auxiliary disassembly and assembly device for molecular pumps, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A molecular pump auxiliary assembly / disassembly device includes a device frame plate, an mounting frame plate is fixedly installed on the lower end face of the device frame plate, a drive motor is fixedly installed on the mounting frame plate, a U-shaped frame plate is fixedly installed on the output shaft of the drive motor, and a rotating circular plate is fixedly installed on the U-shaped frame plate, which is rotatably mounted on the mounting frame plate.

[0007] The rotating circular plate is provided with a positioning component, and the positioning component is provided with symmetrically arranged positioning clamps;

[0008] A pressing component is provided on the rotating circular plate, and a V-shaped pressure rod is provided on the pressing component.

[0012] Preferably, the pressing assembly includes a stabilizing slide fixedly mounted on a rotating circular plate, a stabilizing slider slidably mounted on the stabilizing slide, a double-headed frame fixedly mounted on the stabilizing slider, symmetrically arranged connecting rods rotatably mounted on the double-headed frame, a connecting frame fixedly mounted on the side end face of the positioning clamp, and an inclined cross block fixedly mounted on the upper end face of the stabilizing slider.

[0013] Preferably, the upper end face of the rotating circular plate is fixedly installed with symmetrically arranged L-shaped support rods, the L-shaped support rods are provided with reset grooves, a reset shaft is rotatably installed in the reset grooves, and a torsion spring is fixedly connected to the side end face of the V-shaped pressure rod.

[0014] Preferably, the end of the linkage rod away from the double-headed frame is rotatably mounted on the connecting frame, the V-shaped pressure rod is fixedly mounted on the reset shaft, the end of the torsion spring away from the V-shaped pressure rod is fixedly connected to the inside of the reset shaft, and the position of the torsion spring is on the outside of the reset shaft.

[0015] Preferably, a stabilizing rod is fixedly installed on the lower end face of the device frame plate, and the number of stabilizing rods is four, which are evenly distributed.

[0016] This invention provides an auxiliary device for disassembling and assembling molecular pumps. Compared with the prior art, it has the following advantages:

[0017] 1. In this utility model, the molecular pump that needs to be disassembled is placed on a rotating circular plate. When it is necessary to disassemble or assemble the molecular pump at different positions, the U-shaped frame plate is driven to rotate by the drive motor. The rotating circular plate on the U-shaped frame plate will rotate on the device frame plate. The rotatable rotating circular plate drives the molecular pump to rotate synchronously, which facilitates the disassembly and assembly of the molecular pump and effectively improves the efficiency of disassembly and assembly.

[0018] 2. In this utility model, when the molecular pump rotates with the rotating disc, the positioning motor drives the drive disk to rotate. The mounting shaft on the drive disk drives the drive rod to move. By utilizing the cooperation between the drive rod and the mounting rod, the cooperation between the mounting rod and the positioning slider, and the limiting sliding between the positioning slider and the positioning groove, the two positioning clamps on the rotating disc are effectively driven to move inward simultaneously. The positioning clamps are used to complete the positioning of the molecular pump, ensuring that the molecular pump will not shift or shake when it rotates with the rotating disc, thus improving the effectiveness of the device.

[0019] 3. In this utility model, when the two positioning clamps move inward at the same time, the connecting frame on the positioning clamps will use the linkage rod to drive the stabilizing slider on the double-headed frame to move horizontally on the stabilizing slide. When the stabilizing slider moves, the inclined horizontal block will lift the V-shaped pressure rod. When the V-shaped pressure rod is lifted, one end will rotate around the reset shaft. The other end of the V-shaped pressure rod will press down on the molecular pump, further improving the stability of the molecular pump on the rotating circular plate. Attached Figure Description

A positioning clamp 6 is fixedly mounted on the positioning slider 13 and slidably mounted on the rotating circular plate 5. The drive disk 9 is located below the device frame plate 1, and the mounting rod 14 is located below the device frame plate 1. The two drive rods 11 are arranged at an angle to ensure that the drive disk 9 can drive the drive rod 11 to move when it rotates.

[0030] In this embodiment, when the molecular pump rotates with the rotating disc 5, the positioning motor 8 drives the drive disk 9 to rotate. The mounting shaft 10 on the drive disk 9 drives the drive rod 11 to move. By utilizing the cooperation between the drive rod 11 and the mounting rod 14, the cooperation between the mounting rod 14 and the positioning slider 13, and the limiting sliding between the positioning slider 13 and the positioning groove 12, the two positioning clamps 6 on the rotating disc 5 are effectively driven to move inward simultaneously.

The two connecting rods 18 are arranged at an angle, and the connecting frame 19, the connecting rods 18 and the double-headed frame 17 are on the same horizontal plane.

[0032] In this embodiment, when the two positioning clamps 6 move inward at the same time, the connecting frame 19 on the positioning clamp 6 will use the linkage rod 18 to drive the stabilizing slider 16 on the double-headed frame 17 to move horizontally on the stabilizing slide 15. When the stabilizing slider 16 moves, the inclined horizontal block 20 will lift the V-shaped pressure rod 7. When the V-shaped pressure rod 7 is lifted, one end will rotate around the reset shaft 23. The other end of the V-shaped pressure rod 7 will press down on the molecular pump, further improving the stability of the molecular pump on the rotating circular plate 5.

The mounting shaft 10 on the drive disk 9 will drive the drive rod 11 to move. Utilizing the cooperation between the drive rod 11 and the mounting rod 14, the cooperation between the mounting rod 14 and the positioning slider 13, and the limiting sliding between the positioning slider 13 and the positioning groove 12, there is... The two positioning clamps 6 on the rotating disc 5 move inward simultaneously, and the positioning clamps 6 are used to position the molecular pump, ensuring that the molecular pump will not shift or shake when it rotates with the rotating disc 5. When the two positioning clamps 6 move inward simultaneously, the connecting frame 19 on the positioning clamps 6 will use the linkage rod 18 to drive the stabilizing slider 16 on the double-headed frame 17 to move horizontally on the stabilizing slide 15. When the stabilizing slider 16 moves, the inclined horizontal block 20 will lift the V-shaped pressure rod 7. When the V-shaped pressure rod 7 is lifted, one end will rotate around the reset shaft 23, and the other end of the V-shaped pressure rod 7 will press down on the molecular pump, further improving the stability of the molecular pump on the rotating disc 5.
