[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , the present invention provides the following technical solutions: a steel ball polishing device, comprising a base 1;

[0028] The mounting seat 2 is an annular structure and is rotatably connected to the top of the base 1. A plurality of rotating telescopic components 210 uniformly distributed along its circumference are fixed on the mounting seat 2. The axis of the rotating telescopic component 210 is radially arranged along the mounting seat 2. A material grabbing and grinding component 220 is provided at the outward end of each rotating telescopic component 210. The material grabbing and grinding component 220 can rotate synchronously with the rotating telescopic component 210. A transmission component 230 is provided between the inner end of each rotating telescopic component 210 and the base 1. A power component that drives the mounting seat 2 to rotate is also provided on the base 1. When the power component drives the mounting seat 2 to rotate, on the one hand, a plurality of rotating telescopic components 210 revolve synchronously with the mounting seat 2. During the revolution, the rotating telescopic component 210 generates a self-rotation motion under the action of the transmission component 230;

[0029] The polishing track 3 is an annular tubular structure, the inner wall of the polishing track 3 is provided with a grinding layer, the polishing track 3 is coaxially arranged with the mounting seat 2, and the side of the polishing track 3 close to the mounting seat 2 is provided with an annular feed port 301 with the same height as the rotating telescopic component 210. In this embodiment, the longitudinal section of the feed port 301 is semicircular, so that the bottom of the polishing track 3 is just tangent to the horizontal plane;

[0030] A loading seat 4, which is an annular structure and is located between the polishing track 3 and the mounting seat 2. A loading assembly 410 corresponding to the grabbing and grinding assembly 220 is provided on the loading seat 4. A position detection sensor is provided between the mounting seat 2 and the loading seat 4. When the mounting seat 2 stops rotating, the grabbing and grinding assembly 220 can correspond to the loading assembly 410 one by one.

[0031] A discharge channel 5, wherein the discharge channel 5 is arranged inside the polishing track 3, and an opening 501 is provided on the top of the discharge channel 5, one side of which is connected to the edge of the feed port 301, and the outer edge of the opening 501 is seamlessly connected to the bottom edge of the feed port 301;

[0032] When polishing the steel balls, the steel balls are loaded onto each loading assembly 410 one by one, and the grabbing and grinding assembly 220 is driven to approach the steel balls by rotating the telescopic assembly 210. The grabbing and grinding assembly 220 grabs the steel balls and moves toward the polishing track 3, so that the steel balls contact the grinding layer of the polishing track 3. The mounting seat 2 is then driven to rotate by the power assembly. At this time, the steel balls move with the revolution and rotation of the grabbing and grinding assembly 220 to complete the polishing work in the polishing track 3.

[0033] Specifically, the rotating telescopic assembly 210 includes a fixed seat 211 fixedly connected to the mounting seat 2, a rotating shaft 212 arranged along the radial direction of the mounting seat 2 and rotatably connected to the fixed seat 211, a rotating hole is provided in the fixed seat 211, the rotating shaft 212 passes through the rotating hole and is rotatably connected to the fixed seat 211 through a rotating bearing, and the grabbing and grinding assembly 220 is provided at the outward end of the rotating shaft 212;

[0034] In order to enable the material grabbing and grinding assembly 220 to stably produce linear motion, in a further embodiment, the outward end of the rotating shaft 212 is coaxially slidably connected with a sliding rod 213. In this embodiment, a coaxial sliding hole is provided at the end of the rotating shaft 212 close to the sliding rod 213, and the end of the sliding rod 213 close to the rotating shaft 212 extends into the sliding hole. The cross-section of the sliding hole can be an equilateral triangle, so that only relative sliding can occur between the sliding rod 213 and the rotating shaft 212. A base 214 is coaxially rotatably connected to the sliding rod 213, and a telescopic member 215 is fixedly provided on the fixed seat 211. The telescopic rod of the telescopic member 215 is fixedly connected to the base 214, and the telescopic member 215 is a servo telescopic cylinder.

[0035] Specifically, the transmission assembly 230 includes a driven gear 231 coaxially connected to the inner side of the rotating and telescopic assembly 210, and a transmission gear 232 fixed on the base 1 and coaxially arranged with the mounting seat 2. In this embodiment, the driven gear 231 is coaxially fixedly connected to the rotating shaft 212, and the driven gear 231 and the transmission gear 232 are bevel gears;

[0036] In order to facilitate the stable loading of steel balls of different sizes, in a further embodiment, the loading assembly 410 includes a loading barrel 411 fixed to the top of the loading seat 4, and a fourth magnetic attraction member 412 arranged in the loading barrel 411. The base 1 is also provided with a lifting assembly 420 connected to the loading seat 4. In this embodiment, the lifting assembly 420 is a servo telescopic cylinder, and multiple servo telescopic cylinders are provided, and the telescopic rods thereof face upward and are connected to the loading seat 4.

The first magnetic suction member 222 is an electromagnetic block, and the loading height of the steel ball can be adjusted by the lifting assembly 420, so that the center of the steel ball is at the same height as the axis of the grabbing barrel 221. After the grabbing barrel 221 is close to the steel ball, the first magnetic suction member 222 is activated to adsorb the steel ball to complete the grabbing.

[0038] In order to facilitate the control of the effect between the steel ball and the polishing track 3, in a further embodiment, a third annular magnetic attraction member 302 is coaxially provided on the outer side of the polishing track 3. The third magnetic attraction member 302 is an annular electromagnetic block. The electromagnetic block produces an adsorption effect on the steel ball and the gripping barrel 221 has a resistance effect on the steel ball, so that the polishing intensity of the steel ball can be well controlled.

[0039] The end of the rotating telescopic component 210 is fixedly connected to a guide seat 240, and a guide hole 241 is provided in the guide seat 240. One end of the grabbing barrel 221 extends into the guide hole 241 and is connected thereto through an elastic member. The grabbing barrel 221 slides in cooperation with the guide hole 241 and enables the grabbing barrel 221 to rotate synchronously with the rotating telescopic component 210.

[0040] In order to further enhance the control effect of the polishing intensity and prevent the grabbing barrel 221 from excessively resisting the steel ball, in a further embodiment, the elastic member includes a second magnetic member 242 movably disposed in the guide hole 241, and the second magnetic member 242 is connected to the grabbing barrel 221 via a first rigid spring 243;

[0041] Without starting the third magnetic attraction member 302, the material grabbing cylinder 221 can be driven to contact the steel ball by rotating the telescopic assembly 210. Under the buffering effect of the first rigid spring 243, the steel ball is not prone to over-polishing.

[0042] When the telescopic member 215 does not move, the third magnetic member 302 can be activated to enhance the effect of the steel ball and the polishing track 3 on the one hand, and the second magnetic member 242 can be attracted on the other hand, and the first rigid spring 243 can be squeezed to enhance the resistance effect of the grabbing barrel 221 on the steel ball;

[0043] In order to facilitate real-time monitoring of the resistance effect of the grab barrel 221 on the steel ball, in a further embodiment, a force sensor 244 is fixedly provided at the bottom of the guide hole 241, and the force sensor 244 is connected to the second magnetic suction member 242 through a second rigid spring 245. When polishing, the first rigid spring 243 and the second rigid spring 245 are both in a compressed state, and the resistance effect of the grab barrel 221 on the steel ball can be transmitted to the force sensor 244, so that it can be monitored through the control device, so as to adjust the magnetic parameters of the second magnetic suction member 242 and the third magnetic suction member 302 according to the force feedback, so as to ensure that the steel ball has a suitable polishing effect.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
