[0035] The present invention will be further described below with reference to embodiments.

[0036] Figures 1-16This is an embodiment of an automatic feeding and positioning device for pump body testing according to the present invention, which includes a transport vehicle 1, a slide rail assembly 2, and a lifting and positioning assembly 3. The transport vehicle 1 includes a frame 101, a left support plate 103 and a right support plate 108 fixedly mounted on the upper end of the frame 101. A limiting top block 104 is fixedly mounted on the front end of the upper surface of the left support plate 103, a limiting baffle 105 is fixedly mounted on the left side of the upper surface of the left support plate 103, and a pulley guide rail 107 is fixedly mounted on the right side of the limiting baffle 105. A connector 106 is fixedly provided at the rear end of the limiting baffle 105, and a rotating baffle 10601 is provided at the front end of the connector 106. The rotating baffle 10601 is rotatably connected to the connector 106. A limiting top block 104, a limiting baffle 105, a connector 106, and a pulley guide rail 107 are fixedly provided on the upper surface of the right support plate 108, symmetrically opposite to the left support plate 103. A carrying plate 109 is provided above the two pulley guide rails 107. The width of the carrying plate 109 is equal to the width of the two limiting top blocks 104, the limiting baffle 105, the connector 106, and the pulley guide rail 107. The distances between the baffles 105 are matched. A handle 10901 is fixedly provided on the front side of the loading plate 109. A positioning hole 10902 is provided on the lower surface of the loading plate 109. The positioning hole 10902 is hemispherical or conical in shape. A buffer airbag 111 is provided between the loading plate 109 and the left support plate 103 and the right support plate 108. An inflation port 11101 and an exhaust port 11102 are provided on the side of the buffer airbag 111. The thickness of the buffer airbag 111 after inflation is 50-100mm. An exhaust valve is provided inside the exhaust port 11102. There are 4 exhaust valves. The 4 exhaust valves are located on the four sides of the buffer airbag 111. Since the weight of the vacuum pump is about 20KG, the thickness of the buffer airbag 11 is designed to be 50-100mm. The exhaust speed of the buffer airbag 111 is adjusted by the 4 exhaust valves, which not only ensures that the buffer airbag has a stable cushioning effect, but also saves the exhaust waiting time and improves work efficiency. A caster wheel 102 is fixedly mounted on the lower end of the frame 101. A brake knob 10201 is mounted on the bracket of the caster wheel 102. A handlebar 112 is fixedly mounted on the front side of the frame 101. With this structural design, the vacuum pump to be tested is placed on the loading platform 109 using a small crane. Because a buffer airbag 111 is provided under the loading platform 109, it can play a buffering and protective role, effectively reducing the impact force when the vacuum pump falls and improving the safety of operation. After the vacuum pump is placed on the loading platform 109, the exhaust valve of the buffer airbag 111 is opened to exhaust the air. At the same time, the direction of the loading platform 109 when it is lowered is adjusted by the loading platform handle 10901, so that the loading platform 109 can be slowly placed on the left and right pulley guide rails 107. It is then limited and fixed by the limiting top block 104 and the limiting baffle 105. At the same time, the rotating baffle 10601 of the connector 106 is rotated inward to limit and fix the rear end of the loading platform 109.

[0037] The slide rail assembly 2 includes a slide rail fixing plate 201, a slide rail left support plate 202, a slide rail right support plate 203, and a control switch 204. The slide rail left support plate 202, the slide rail right support plate 203, and the control switch 204 are fixedly connected to the slide rail fixing plate 201. A limit baffle 105 is fixedly provided on the left side of the upper surface of the slide rail left support plate 202, and a pulley guide rail 107 is fixedly provided on the right side of the upper surface of the slide rail left support plate 202. A limit baffle 105 is fixedly provided on the right side of the upper surface of the slide rail right support plate 203, and a pulley guide rail 107 is fixedly provided on the left side of the upper surface of the slide rail right support plate 203. There are multiple slide rail assemblies 2. The control switch 204 is fixedly connected to the upper surface of the outermost slide rail fixing plate 201. The slide rail assembly 2 is fixedly connected to the three-dimensional worktable 4 via the slide rail fixing plate 201. The transport vehicle 1 connects the pulley guide rails 107 on the left support plate 103 and the right support plate 108 with the pulley guide rails 107 on the slide rail assembly 2 via the plug-in connector 106. Rotating the rotating baffle 10601 upwards opens the rotating baffle 10601, and pushing the load plate handle 10901 allows the vacuum pump to slide from the transport vehicle 1 onto the slide rail assembly 2. It features simple and convenient operation, saving time and effort.

[0038] In this embodiment, the lifting and positioning assembly 3 includes a lifting fixed plate 301, a lifting left support plate 302, and a lifting right support plate 303. The lifting left support plate 302 and the lifting right support plate 303 are located at the left and right ends of the upper surface of the lifting fixed plate 301, respectively. The lifting left support plate 302 is connected to the lifting fixed plate 301 via a cylinder 304. The cylinder body of the cylinder 304 is fixedly connected to the lifting fixed plate 301, and the piston of the cylinder 304 is fixedly connected to the lifting left support plate 302. The lifting fixed plate 301 and the lifting left support plate 302 are sequentially positioned... The system includes a lower guide seat 306, a guide rod 305, and an upper guide seat 307. The lower guide seat 306 is fixedly connected to the lifting fixed plate 301, and the upper guide seat 307 is fixedly connected to the lifting left support plate 302. The lower guide seat 306 and the upper guide seat 307 are slidably connected through the guide rod 305. The connection method between the lifting right support plate 303 and the lifting fixed plate 301 is the same as that between the lifting left support plate 302 and the lifting fixed plate 301. The inner sides of the lifting left support plate 302 and the lifting right support plate 303 are symmetrically provided with pulley guide rails 107.

[0039] The upper surface of the lifting fixing plate 301 has multiple limiters 308 at its rear end. The upper surface of the lifting fixing plate 301 has a positioning component 309. The positioning component 309 includes a positioning fixing seat 30901. The positioning component 309 is fixedly connected to the lifting fixing plate 301 through the positioning fixing seat 30901. The upper end of the positioning fixing seat 30901 is fixedly provided with a positioning post 30902. The upper end of the positioning post 30902 is provided with a positioning protrusion 30903. The positioning protrusion 30903 is hemispherical or conical in shape.

[0040] In one specific embodiment, there are three positioning holes 10902 and three positioning protrusions 30903, and the three positioning holes are distributed in a triangular pattern.

[0041] As shown in the figure, the lower guide seat 306 includes a guide base 30601. A retaining ring 30602 is located at the upper end of the guide base 30601. A transverse groove 30603 is located in the middle of the retaining ring 30602, and a longitudinal groove 30604 is located in the upper half of the retaining ring 30602. The longitudinal groove 30604 intersects with the transverse groove 30603. Locking screw holes 30605 are located on both sides of the longitudinal groove 30604 and in the upper half of the retaining ring 30602. This structural design makes the lower guide seat 306 easy to install and reliably fixed, facilitating the installation and fixation of the guide rod 305.

[0042] The lifting and positioning assembly 3 is fixedly connected to the three-dimensional worktable 4 via the lifting fixing plate 301. The pulley guide rail 107 on the lifting and positioning assembly 3 is aligned with the pulley guide rail 107 on the slide rail assembly 2. Pushing the work plate handle 10901 will slide the vacuum pump from the slide rail assembly 2 to the lifting and positioning assembly 3, and limit its position through the limiter 308. The control switch 204 controls the cylinder 304 to push the lifting left support plate 302 and the lifting right support plate 303 to move up and down, thereby driving the work plate 109 to rise and fall. When the work plate 109 falls, it is positioned by the positioning hole 10902 and the positioning protrusion 30903. Since there are three positioning holes 10902 and three positioning protrusions 30903, which are arranged in a triangle, and the shapes of the positioning holes 10902 and the positioning protrusions 30903 are hemispherical or conical, accurate positioning can be achieved, improving the accuracy of testing and increasing work efficiency.

[0043] This invention provides an automatic loading and positioning device for pump body testing. The device uses a transport vehicle for loading, unloading, and transporting the pump body. A buffer airbag and limiting structure design ensure convenient and safe operation. Automatic loading of the pump body is achieved through a pulley guide rail. A structural design combining a lifting positioning component, positioning holes, and positioning protrusions precisely fixes the pump body under test, improving testing accuracy, increasing work efficiency, and saving labor costs. This invention is applicable to the loading and testing of vacuum pumps and their components.
