Description
Technical Field
[0001] This utility model relates to the field of automatic testing equipment, and in particular to an automatic testing device for centrifugal transmissions. Background Technology
[0002] A centrifugal gearbox is a mechanical speed-changing device that automatically adjusts the speed ratio using the principle of centrifugal force. It is widely used in various mechanical equipment. One of the main components of a food processor or mixer is the centrifugal gearbox. The centrifugal gearbox includes a base, a top plate, and a spring. Two actuators are symmetrically arranged on both sides of the base, and the actuators are hinged to the top plate. When the centrifugal gearbox rotates at high speed, the actuators expand outward, causing the top plate to compress the spring. An important indicator of the centrifugal gearbox is whether the expansion of the two actuators is within a specific range at the rated rotation speed. Currently, there is no efficient and automated device to measure this indicator of the centrifugal gearbox. Utility Model Content

[0013] See Figure 6 This is a perspective view of the centrifugal gearbox 400 of the food processor. It mainly includes a base 403, on which a top plate 404 and a spring 402 are mounted. The top plate 404 compresses the spring 402 and is mounted on the base 403. The top plate 404 can slide up and down within the base 403. Two actuating blocks 401 are symmetrically arranged on both sides of the base 403, and are hinged to the top plate 404 via two connecting legs. When the centrifugal gearbox 400 rotates at high speed, under the action of centrifugal force, the actuating blocks 401 expand outwards. The connecting leg of the moving block 401 will drive the top plate 404 to compress the spring 402 downward. When the centrifugal force and the elastic force of the spring are balanced, the moving block 401 will rotate to form a circle with a constant diameter. An important indicator of the centrifugal gearbox 400 is whether the expansion size of the two moving blocks 401 (the diameter of the rotating circle) is within a specific range at the rated rotation speed. Currently, there is no efficient and automated device to measure this indicator of the centrifugal gearbox. The automatic detection device of this utility model is designed to solve this problem.
[0014] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "Automatic Detection Device for Centrifugal Transmission" is provided in conjunction with the accompanying drawings.
[0015] See Figures 1-3 In this embodiment, the automatic detection device includes a workbench 100, on which a clamping mechanism 200 and a detection mechanism 300 are provided. The detection mechanism 300 includes a push cylinder 301 and a sliding seat 303 disposed on a guide rail 302. The movable end of the push cylinder 301 is fixedly connected to the sliding seat 303. A rotary motor 304 is disposed on the sliding seat 303. The rotating head 305 of the rotary motor 304 is vertically upward. A first linear slide module 306 is also disposed on the sliding seat 303. A laser measuring instrument 307 is disposed on the slide of the first linear slide module 306. The detection mechanism 300 also includes a fixed frame 308. A pressing cylinder 309 is disposed on the fixed frame 308. A rotating pressure column 310 is disposed vertically downward on the movable end of the pressing cylinder 309. The rotating pressure column 310 is rotatably disposed on the movable end of the pressing cylinder 309. During operation, the clamping mechanism 200 clamps the centrifugal gearbox 400 and mounts it on the rotating head 305. Then, the pushing cylinder 301 drives the sliding seat 303 to slide forward along the guide rail 302, causing the rotating head 305 to move directly below the rotating pressure column 310. Next, the pressing cylinder 309 drives the rotating pressure column 310 downwards to press against the centrifugal gearbox 400, preventing it from detaching from the rotating head 305. Afterwards, the rotating motor 304 drives the centrifugal gearbox 400 to rotate at its rated speed via the rotating head 305. Once the rotation stabilizes, the first linear slide module 306 drives the laser measuring instrument 307 to move closer to the centrifugal gearbox, so that the laser beam of the laser measuring instrument is externally tangent to the circle formed by the high-speed rotating moving blocks 401. This measures whether the expansion range of the two moving blocks 401 of the centrifugal gearbox 400 at the rated speed meets the standard, determining whether the centrifugal gearbox 400 is qualified. This automatic detection device can efficiently and automatically detect centrifugal gearboxes.
[0016] It should be noted that both the clamping mechanism 200 and the detection mechanism 300 of the automatic detection device are electrically connected to the central controller. Through the control method of the existing technology, the automatic linkage of the clamping mechanism 200 and the detection mechanism 300 is realized. For example, in this embodiment, a positioning element 311 is provided on the slide of the first linear slide module 306, and a position sensor 312 is provided on the sliding seat 303. The position sensor 312 is located on the moving path of the positioning element 311. The position sensor 312 is electrically connected to the central controller to detect and control the sliding seat 303 to move into place.

A horizontal cylinder 203 is mounted on the slide of the second linear slide module 202. A vertical cylinder 204 is mounted on the movable end of the horizontal cylinder 203. The movable end of the vertical cylinder 204 faces vertically downwards, and a clamping cylinder 205 is mounted on the movable end of the vertical cylinder 204. A chuck 206 is mounted on the movable end of the clamping cylinder 205 to clamp the centrifugal transformer. Speed reducer 400; during operation, the second linear slide module 202 controls the horizontal cylinder 203 and the vertical cylinder 204 to move left and right above the clamping / installation position. The horizontal cylinder 203 controls the vertical cylinder 204 to move back and forth to directly above the clamping / installation position. The vertical cylinder 204 drives the clamping cylinder 205 to move downwards closer to the clamping / installation position to clamp / install the centrifugal speed reducer 400, thereby realizing the automated clamping / installation of the centrifugal speed reducer 400.
[0018] See further Figure 5 In this embodiment, a support frame 207 is fixedly mounted on the slide of the second linear slide module 202. A horizontal cylinder 203 is mounted on the support frame 207, and a horizontal slide rail 208 is mounted on the support frame 207. A first slider 209 is slidably mounted on the horizontal slide rail 208, and the movable end of the horizontal cylinder 203 is fixedly connected to the first slider 209. A vertical cylinder 204 is mounted on the first slider 209, and a vertical slide rail 210 is mounted on the first slider 209. A second slider 211 is slidably mounted on the vertical slide rail 210, and the sliding end of the vertical cylinder 204 is fixedly connected to the second slider 211. A clamping cylinder 205 is mounted on the second slider 211. During operation, the horizontal cylinder 207 drives the first slider 209 to slide back and forth along the horizontal slide rail 208, and the vertical cylinder 204 drives the second slider 211 to slide up and down along the vertical slide rail 210, ensuring that the clamping cylinder 205 slides stably back and forth and up and down to the corresponding position.
[0019] More specifically, in this embodiment, vertical cylinders 204 and vertical slide rails 210 are provided on both the left and right sides of the second slider 211. The second slider 211 is provided on each of the vertical slide rails 210, and clamping cylinders 205 are provided on each of the second sliders 211.
