Description

Technical Field

[0001] This utility model belongs to the field of molecular pump assembly technology, specifically relating to auxiliary tooling for molecular pump assembly. Background Technology

[0002] Molecular pump assembly refers to the process of combining the various components of a molecular pump into a complete functional unit through a series of operations such as precise positioning, connection and debugging, according to design requirements and technical specifications. This process must be carried out under strict environmental control to ensure that the molecular pump achieves performance indicators such as high vacuum, high pumping speed and low vibration.

[0003] However, due to their large size, molecular pumps require a lot of manpower to lift or move during assembly. The existing support structures are mostly fixed designs, and when position or height adjustment is required, the operation is cumbersome and laborious, which not only leads to low assembly efficiency, but also increases equipment wear and safety hazards caused by frequent handling.

[0004] To address the aforementioned issues, this application proposes auxiliary tooling for assembling molecular pumps. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an auxiliary tooling for assembling molecular pumps, which has the characteristic of improving the assembly efficiency of molecular pumps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tooling for assembling a molecular pump, including a slot frame, a brake motor disposed on the left side of the slot frame, a controller disposed on the front side of the slot frame, a sliding frame slidably connected inside the slot frame, a threaded rod rotatably connected to the inner wall of the slot frame, the outer surface of the threaded rod being threadedly connected to the inner wall of the sliding frame, the power output end of the brake motor being fixedly connected to the left end of the threaded rod, a connecting frame disposed below the sliding frame, a telescopic frame slidably connected inside the connecting frame, a placement plate disposed below the telescopic frame, and electric push rods disposed on both sides of the connecting frame.

[0007] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the upper surface of the slot frame, and two sets of fixing pins are provided inside the connecting plate.

[0008] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the back of the controller, and the back of the fixing plate is fixedly connected to the front of the slot frame.

[0009] As a preferred embodiment of this utility model, a connecting seat is fixedly connected to the upper surface of the brake motor, and the right side of the connecting seat is fixedly connected to the left side of the slot frame.

[0010] As a preferred embodiment of this utility model, a fixing block is fixedly connected to the bottom surface of the sliding frame, and the bottom surface of the fixing block is fixedly connected to the upper surface of the connecting frame.

[0011] As a preferred embodiment of this utility model, mounting plates are fixedly connected to both sides of the connecting frame, and the bottom surface of each mounting plate is fixedly connected to the top end of the electric push rod.

[0012] As a preferred embodiment of this utility model, each of the electric push rods has a movable frame fixedly connected to its telescopic end, and the two movable frames are respectively fixedly connected to the two sides of the telescopic frame on their respective sides.

[0013] As a preferred embodiment of this utility model, the two sides of the placement plate are fixedly connected to a fixing frame, and the upper surface of the fixing frame is fixedly connected to the bottom surface of the telescopic frame.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: the controller enables the equipment to start and stop and adjust parameters, making operation convenient and efficient. The placement plate provides a stable support platform for the molecular pump, while the telescopic function of the electric push rod precisely moves the telescopic frame within the connecting frame, thereby achieving height adjustment of the placement plate and the molecular pump to meet the needs of different assembly stations. Furthermore, the brake motor drives the threaded rod to rotate, which in turn drives the sliding frame to slide smoothly within the slot frame, enabling the connecting frame, telescopic frame, placement plate, and molecular pump to achieve horizontal displacement as a whole. This design, through the coordinated operation of vertical lifting and horizontal movement, effectively reduces the workload of manual handling and adjustment, significantly improves the assembly efficiency of the molecular pump, and ensures accurate positioning, reducing assembly errors.

Example

[0023] Please see Figure 1-5 The present invention provides the following technical solution: an auxiliary tooling for assembling a molecular pump, including a slot frame 1, a brake motor 2 on the left side of the slot frame 1, a controller 3 on the front of the slot frame 1, a sliding frame 9 slidably connected inside the slot frame 1, a threaded rod 8 rotatably connected to the inner wall of the slot frame 1, the outer surface of the threaded rod 8 being threadedly connected to the inner wall of the sliding frame 9, the power output end of the brake motor 2 being fixedly connected to the left end of the threaded rod 8, a connecting frame 12 being provided below the sliding frame 9, a telescopic frame 14 being slidably connected inside the connecting frame 12, a placement plate 17 being provided below the telescopic frame 14, and electric push rods 11 being provided on both sides of the connecting frame 12;

[0024] In this embodiment, the threaded rod 8 and the sliding frame 9 are connected by a threaded transmission. When the threaded rod 8 rotates under the drive of the brake motor 2, the sliding frame 9 can slide linearly along the inner wall of the slot frame 1. This design utilizes the precise transmission characteristics of the threaded pair to convert rotational motion into smooth linear displacement.

[0025] Specifically, a connecting plate 5 is fixedly connected to the upper surface of the slot frame 1. Two sets of fixing pins 6 are provided inside the connecting plate 5. In this embodiment, the connecting plate 5 can be penetrated and fixed in a suitable position by fixing the fixing pins 6. At the same time, the slot frame 1 can be fixed in a suitable position by fixing the connecting plate 5.

[0026] Specifically, a fixing plate 4 is fixedly connected to the back of the controller 3. The back of the fixing plate 4 is fixedly connected to the front of the slot frame 1. In this embodiment, the controller 3 can be fixed by the fixing plate 4. At the same time, the controller 3 is a programmable logic controller (PLC), which is electrically connected to the brake motor 2 and the electric push rod 11 through digital or analog I / O interfaces to control the coordinated action of each component.

[0027] Specifically, a connecting seat 7 is fixedly connected to the upper surface of the brake motor 2. The right side of the connecting seat 7 is fixedly connected to the left side of the slot frame 1. In this embodiment, the brake motor 2 can be fixed by the connecting seat 7. At the same time, the brake motor 2 refers to a power device that integrates a mechanical braking device at the end of the motor shaft, which realizes the function of braking when the power is cut off or braking on demand through electromagnetic or mechanical force.

[0028] Specifically, a fixing block 10 is fixedly connected to the bottom surface of the sliding frame 9. The bottom surface of the fixing block 10 is fixedly connected to the upper surface of the connecting frame 12. In this embodiment, the connecting frame 12 can be fixed to the sliding frame 9 through the fixing block 10, so that the sliding frame 9 can drive the connecting frame 12 to move.

[0029] Specifically, mounting plates 13 are fixedly connected to both sides of the connecting frame 12. The bottom surface of each mounting plate 13 is fixedly connected to the top of the electric push rod 11. In this embodiment, the electric push rod 11 can be fixed to the connecting frame 12 through the mounting plates 13, and the electric push rod 11 can be stably extended and retracted.

[0030] Specifically, each electric push rod 11 is fixedly connected to a movable frame 15 at its telescopic end. The two movable frames 15 are fixedly connected to the two sides of the telescopic frame 14 on their respective sides. In this embodiment, the electric push rod 11 and the telescopic frame 14 can be fixed by the movable frame 15, so that the electric push rod 11 can drive the telescopic frame 14 to move.

[0031] Specifically, a fixing frame 16 is fixedly connected to both sides of the placement plate 17. The upper surface of the fixing frame 16 is fixedly connected to the bottom surface of the telescopic frame 14. In this embodiment, the fixing frame 16 can connect the placement plate 17 to the telescopic frame 14, and enable the telescopic frame 14 to move the placement plate 17.

[0032] The working principle and usage process of this utility model are as follows: In use, firstly, the slot frame 1 is fixed at the assembly station using the connecting plate 5 and the fixing pin 6 to ensure the stability of the tooling. Then, the power supply to the controller 3 is turned on, and parameters are set through its panel. The brake motor 2 drives the threaded rod 8 to rotate, causing the sliding frame 9 to slide horizontally along the inner wall of the slot frame 1, moving the connecting frame 12, the telescopic frame 14, and the placement plate 17 to the molecular pump loading position. At this time, the electric push rod 11 retracts, lowering the placement plate 17 to its lowest position. Manually or with auxiliary equipment, the molecular pump housing is placed on the placement plate 17 and temporarily fixed with limit blocks or straps. When positioned, according to assembly requirements, the controller 3 controls the extension and retraction of the electric push rod 11, which in turn drives the telescopic frame 14 to the connecting frame 15. The height of the molecular pump housing is precisely adjusted by raising and lowering the frame 12. Simultaneously, the brake motor 2 drives the threaded rod 8 to rotate, causing the sliding frame 9 to move horizontally until the flange interface of the molecular pump housing is aligned with the target component. After positioning, the brake motor 2 is de-energized and self-locked, and the electric push rod 11 maintains its current stroke to ensure the molecular pump housing is stably fixed. The operator can then perform assembly operations such as bolt tightening and sealing. After assembly, the electric push rod 11 descends to the low position, releasing the limiting device on the placement plate 17, and the assembled molecular pump is removed. Finally, the sliding frame 9 and the telescopic frame 14 are controlled to return to their initial positions, and the power is turned off to complete the operation. This effectively replaces traditional manual handling and fixed support, significantly improving assembly efficiency and reducing positioning errors.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
