Compared with the current transfer and installation equipment, it can automatically and more accurately perform the sequential docking and assembly of the vacuum pump related components from top to bottom while achieving low-level transfer, which not only greatly reduces the labor intensity of workers, but also greatly improves the production efficiency of the vacuum pump.

[0042] As an embodiment of the present invention, Fig.10 and Fig.11As shown, both sides and the upper surface of the fixed base 22 are provided with straight-line extending supports, wherein the supports on the upper surface are provided as support brackets 221, and the upper ends of the support brackets 221 are rotatably connected to the bearing seat 219, and a worm 225 is rotatably provided inside the fixed base 22 on the same straight line as the extending supports on both sides, and a worm gear 226 is meshingly provided on one side of the worm gear 225, and the worm gear 226 is rotatably provided inside the fixed base 22, and the upper end of the wheel shaft is fixed to a universal shaft 227, and is transmission-connected to the impeller shaft of a fan 228 installed on the upper surface of the fixed base 22 through the universal shaft 227, and an exhaust port connected to the outside is provided inside the fixed base 22 below the fan 228 The worm 225 is composed of two freely rotatable rods, and the separated ends of the two rods extend into the interior of the two side branches and are fixed to a bevel gear set 224 rotatably arranged inside the branches. The bevel gear set 224 is composed of two bevel wheels, and a bevel wheel shaft located on the lower side is fixed to a driven gear 223 rotatably arranged inside the fixed base 22. One side of the driven gear 223 is meshed with a driving tooth ball 222 rotatably arranged at the ends of the two side branches of the fixed base 22. The spherical surface of the driving tooth ball 222 protrudes from the fixed base 22, and is always in active friction contact with the surface of the conveying frame 11, and maintains a friction rolling relationship.

[0043] During operation, the driving tooth ball 222 will always be in contact with the surface of the conveying rack 11 and will be driven by the friction of the conveying rack 11. The rotating driving tooth ball 222 will mesh with the driven gear 223, and then the driven gear 223 will coaxially drive the bevel gear set 224 to rotate, and the bevel gear set 224 will coaxially drive the worm 225 connected to itself to rotate, and then the rotating worm 225 will mesh with the worm wheel 226, and the rotating worm wheel 226 will drive the fan 228 through the universal shaft 227, so that the fan 228 continues to blow air toward the surface of the positioned parts.

[0044] To summarize, by fixing the base 22, the driving ball 222, the driven gear 223, the bevel gear set 224, the worm 225, the worm wheel 226, the universal joint 227 and the fan 228, the driving ball 222 can be driven to rotate by utilizing the friction force with the surface of the transfer structure 1 during the transfer of the vacuum pump related components and the consignment structure 2, and the worm 225 can be driven to rotate in coordination with the driven gear 223 and the bevel gear set 224, so that the worm 225 performs the meshing transmission of the worm wheel 226, and the fan 228 is continuously driven in turn, so that it can continuously blow air to the surface of the vacuum pump related components during the transportation process to avoid the diffusion of smoke and dust from the surrounding environment to the vacuum pump related components. At the same time, the dust on the surface of the vacuum pump related components can be cleaned, which is more conducive to the clean installation of the vacuum pump and improves the quality of vacuum pump production.

[0045] Working principle: First, follow Figure 1 and Figure 2The device is installed and it is ensured that the upper end of the auxiliary electric push frame 3 can be stably fitted with the lower end of the bottom support plate 216, and then it can be put into production after adjustment. When working, first place the mounting frame of the vacuum pump between the auxiliary electric push frames 3 and position it according to the pre-designed position, then move the lowest part to the low position of the transfer structure 1, and place the part between the positioning arms 21. When the part is lowered, the gravity of the part will be applied to the surface of the support plate 218, so that the support plate 218 drives the gravity carrier plate 214 to move downward along the positioning arm 21 with the assistance of the sliders at both ends to compress the pressure relief spring 215. When moving downward, the gravity carrier plate 214 will drag the pull rod 213, and drag the inclined push plate 212 downward through the pull rod 213. The downwardly moved inclined push plate 212 will pass through the inclined The inclined plane array box 211 is pushed toward the outside of the positioning arm 21. During the movement of the inclined plane array box 211, the spring positioning rod 2111 will gradually contact the parts and perform flexible top pressure positioning on the parts until the parts are fixed and stable. Then, the parts such as bearings, sealing rings and crank structures can be assembled between the positioning arms 21 to form a complete body of the lower structure of the vacuum pump. Then, the transfer structure 1 is controlled to carry out stable transportation of the consignment structure 2 and the lower part of the pump structure by first lifting them upward and then reversing and dropping them downward according to the specified path. During the entire transportation process, the parts always remain in a vertical upward state under the action of gravity. At the same time, as the consignment structure 2 is transported by the transfer structure 1, the driving gear ball 222 will always be in contact with the conveying rack 11. The rotating driving tooth ball 222 will mesh with the driven gear 223, and then the driven gear 223 will coaxially drive the bevel gear set 224 to rotate, and the bevel gear set 224 will coaxially drive the worm 225 connected to itself to rotate, and then the rotating worm 225 will mesh with the worm wheel 226, and the rotating worm wheel 226 will drive the fan 228 through the universal shaft 227, so that the fan 228 continues to blow air toward the surface of the positioned parts to prevent the surrounding dust from drifting to the parts and the dust on the parts themselves from being blown away, until the bottom support plate 216 contacts the upper end of the auxiliary electric push rack 3, and the auxiliary electric push rack 3 will extend upward according to the specified distance, and the extension length and number of times are the same as The assembly parts of the vacuum pump are related. Under the continued transmission of the transfer structure 1, the auxiliary electric push frame 3 will support the bottom support plate 216 upward, and then the bottom support plate 216 will push the laminated push rod 2161 upward, so that the laminated push rod 2161 is gradually inserted into the sliding holes opened by the sliders at both ends of the gravity carrier plate 214, and the spring clamping plate 2184 is pushed up and separated from the gear shaft 2182 before meshing and transmitting with the gear shaft 2182, so as to release the positioning state of the gear shaft 2182, and then the laminated push rod 2161 continues to move upward and meshes with the gear shaft 2182, driving the gear shaft 2182 to rotate ninety degrees, so that the gear shaft 2182 will release the support state of the lower structure of the pump, and then the rod body of the laminated push rod 2161 will be supported on the surface of the gravity carrier plate 214,The gravity carrier plate 214 is pushed upward, and the upward gravity carrier plate 214 pushes the inclined push plate 212 upward and resets through the pull rod 213. The reset inclined push plate 212 releases the support state of the inclined array box 211, and under the action of the spring, drags the spring positioning rod 2111 along the inner wall of the positioning arm 21 to retract and reset, and gradually releases the positioning state of the lower structure of the pump. Then the lower structure of the pump will be accurately docked with the mounting frame and fixed with the assistance of the workers. Then the auxiliary electric push frame 3 will be reset to a lower position without affecting the transfer structure 1 to the transport structure 2. Then the transfer structure 1 will continue to transport the transport structure 2, reset it to its initial position, and install and transport the remaining components again.
