Description

[0001] The invention relates to the technical field of polishing equipment, and in particular to a fully automatic polishing device and method for stainless steel parts. Background Art

[0002] Stainless steel parts need to be polished when they enter the factory to reduce surface burrs. The polishing of flat workpieces often uses handheld unit surfaces to polish in sequence to achieve the polishing effect of the workpiece. However, when grinding and polishing bottle cap-shaped, cover-shaped, and concave workpieces, it is necessary to consider the polishing method of the inner surface. For large workpieces, sandblasting and shot blasting can be used for polishing, but for small workpieces, the above methods cannot guarantee accuracy, and cannot perform complete polishing tasks on the inner and outer surfaces of metal cover workpieces. They cannot be applied to the polishing of a large number of workpieces in the system, resulting in extremely poor work efficiency and affecting economic benefits.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention uses a rotary polishing group, a vertical polishing group, and a transverse polishing group to generate two different modes and different positions of relative rotation of the metal cover. One is a rotary polishing combination of the vertical polishing group and the rotary polishing group, that is, the planar force inside the metal cover drives the metal cover to generate a new centrifugal rotation force. When the friction force of the top vertical polishing group is not applied, the metal cover will rotate with the rotation of the transmission shaft one. When the force of the vertical polishing group is applied, it is a longitudinal and downward friction force, which will generate a relative and continuous sliding force with the horizontal rotation force brought by the top grinding head of the transmission shaft one, thereby completing the double-sided polishing of the inside and outside of the metal cover while keeping the metal cover rotating. The two-way force can force the inner surface and the outer surface of the metal cover to have more contact with the grinding surface, thereby reducing the grinding gap node time;

[0029] The second is a differential or reverse speed polishing combination of the transverse polishing group and the rotary polishing group. During differential polishing, the grinding direction of the transverse polishing group is the same as that of the rotary polishing group, but the rotation speed is different, thereby generating a speed difference between the inside and the outside, thereby enabling the inner and outer surfaces to obtain more compact friction polishing; in addition, reverse speed polishing has a better polishing effect, that is, when the rotation direction of the grinding wheel belt 2 of the transverse polishing group is opposite to that of the transmission shaft 1, the inner and outer surfaces of the metal cover generate forces in different directions, and when the speed difference is 0, it can even reach the ideal limit state where the rotation speeds of the grinding wheel belt 2, the transmission shaft 1, and the metal cover are the same, which can better ensure the polishing efficiency of the metal cover and reduce the polishing time;

[0030] The devices used in this device are all mechanical actions that can be operated individually. Their action states are reliable and can be adjusted in time. The polishing direction can be freely changed according to the position angle on the fixed platform disc. They can be better applied in systematic continuous production and have extremely strong applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] A vertical polishing group 2 and a horizontal polishing group 3 are arranged on the peripheral side of the rotating polishing group 1.

For the transmission shaft 2 402, it is preferably three or more, and the three diagrams are as shown in FIG. Figure 3 As shown, the two auxiliary transmission shafts 402 can be in a non-driven driving state, which can achieve two beneficial effects: synchronizing the transmission shaft 402 and increasing the inspection area, so that the operator can obtain a better working gap and avoid the decrease in efficiency caused by mental tension. In Figure 5, the bracket 109 is an enlarged bottom support, and its radius is not limited to the size shown in the figure. Its radius can be larger than the meshing thickness of the meshing pile 108 and the transmission belt 110 to prevent the transmission belt 110 from rotating and coming off the bottom.

[0057] Please refer to Figure 1-3 , Figure 5 The transmission shaft 104 includes a meshing pile 108 that is transmitted to the transmission belt 110, and a clamping joint 106 is provided on the top of the meshing pile 108.

[0060] Please pay attention to Figure 1-3 The vertical polishing group 2 includes a stand 201 and a driving motor 205. The two columns of the stand 201 are provided with longitudinal movable groups 202. The longitudinal movable groups 202 include two vertical guide belts 213. The two vertical guide belts 213 are provided with transverse movable groups 204. A fixed wing plate 211 is provided on one side of the side fixing frame 206 to connect with the transverse movable group 204. The oblique movable group 203 and the polishing wheel shaft 210 are fixed inside the side fixing frame 206.

[0061] The side fixing frame 206 is also provided with a driving shaft 207, and the grinding wheel belt 208 is connected to the driving shaft 207, the oblique movable group 203, and the outside of the polishing wheel shaft 210; one end of the driving shaft 207 is connected to the output end of the driving motor 205;

[0062] The oblique movable group 203 includes two guide guardrails 218 and a central axis 217 installed between the side fixing frames 206. The two central axes 217 are connected to a movable cylinder 215. One end of the movable cylinder 215 is provided with a push plate 216. One end of the push plate 216 is connected to an oblique lifting shaft 209. Both ends of the oblique lifting shaft 209 are provided with side shafts 219 connected to the guide guardrails 218. The outer surface of the oblique lifting shaft 209 is frictionally transmitted with the grinding wheel belt 208.

[0063] Please pay attention to Figure 1 A groove is provided on one side of the driving motor 205, and the translation guide block 212 preferably includes an auxiliary guide block 214, and the auxiliary guide block 214 and the groove of the driving motor 205 match each other for translational sliding.

[0064] In one of the embodiments of the present invention: the vertical surface and the inner surface of the metal are polished in this embodiment, specifically, the vertical polishing group 2 and the rotating polishing group 1 are combined, that is, the internal force of the metal cover 5 in the plane direction drives the metal cover 5 to generate a new centrifugal rotational force. When the friction force of the top vertical polishing group 2 is not applied, the metal cover 5 will rotate with the rotation of the transmission shaft 104. When the force of the vertical polishing group 2 is applied, it is a longitudinal and downward friction force, which will generate a relative and continuous sliding force with the horizontal plane rotational force brought by the grinding head 107 on the top of the transmission shaft 104, thereby completing the double-sided polishing of the inside and outside of the metal cover 5 while keeping the metal cover 5 rotating. The two-way force can force the inner and outer surfaces of the metal cover 5 to have more contact with the grinding surface, thereby reducing the grinding gap node time. The specific action is to move the stand 2 01 to the edge of the fixed platform 101, first adjust the oblique movable group 203 to make the oblique lifting shaft 209 push out and fill the inner diameter of the entire grinding wheel belt 208, and make the grinding wheel belt 208 close to the upper surface of the metal cover 5 by adjusting the longitudinal movable group 202 and the transverse movable group 204. After starting to polish, the extension force of part of the movable cylinder 215 can be released, so that the grinding wheel belt 208 undergoes elastic deformation. At this time, the entire grinding wheel belt 208 falls, so that when the polishing wheel shaft 210 rotates, the friction between the grinding wheel belt 208 and the surface of the metal cover 5 is more closely fitted, and the friction force is greater. After polishing the top of a metal cover 5, lift the oblique lifting shaft 209 again to reduce the static friction between the grinding wheel belt 208 and the metal cover 5 as much as possible, thereby preventing the next metal cover 5 from rotating into the polishing position and preventing the previous metal cover 5 from being dragged out of the polishing position.

[0065] Please pay attention to Figure 1 , Figure 2 The horizontal polishing group 3 also includes a horizontal frame 301, on which a horizontal fixing frame 302 is installed, one side of the horizontal fixing frame 302 is provided with a plane transmission shaft 304 connected to the plane grinding group 303, and the other side of the horizontal fixing frame 302 is connected to a second driving motor 305, and the second grinding wheel belt 306 is connected to the plane grinding group 303 and the driving end of the second driving motor 305 for transmission;

[0066] The plane grinding group 303 includes multiple layers of plane grinding wheels 307, and the gap between two adjacent plane grinding wheels 307 is greater than or equal to the thickness of the fixed platform 101;

[0067] The horizontal frame 301 is provided with a fixed rail 309, and the horizontal fixed frame 302 is connected with two longitudinal brackets 308, and the longitudinal brackets 308 cooperate with the fixed rail 309. The top of the horizontal frame 301 is provided with a lifting motor 310, and the output end of the lifting motor 310 is connected with a transmission shaft three 311. The longitudinal bracket 308 is provided with a transmission pile 312, and the transmission pile 312 is connected to the transmission shaft three 311.

[0068] In yet another embodiment of the present invention:

[0069] In this embodiment, the metal surface of the side and inner surface is shown. The polishing is specifically a differential or reverse polishing combination of the transverse polishing group 3 and the rotating polishing group 1. During the differential polishing, the grinding direction of the transverse polishing group 3 is the same as that of the rotating group 1, but the rotation speed is different, thereby generating a speed difference between the inner and outer surfaces, thereby enabling the inner and outer surfaces to obtain more and tighter friction polishing; in addition, the reverse speed polishing has a better polishing effect, that is, when the rotation direction of the grinding wheel belt 2 306 of the transverse polishing group 3 is opposite to that of the transmission shaft 104, the inner and outer surfaces of the metal cover 5 generate forces in different directions, and the speed difference between the inner and outer surfaces is different. When the difference is 0, it can even reach the ideal limit state that the grinding belt 2 306, the transmission shaft 104, and the metal cover 5 have the same rotation speed, which can better ensure the polishing efficiency of the metal cover 5 and reduce the polishing time. The specific action is to move the horizontal frame 301 so that the plane grinding group 303 is close to the metal cover 5, and the height of the grinding disc of the plane grinding group 303 is adjusted in time by lifting the motor 310, and the gap between the plane grinding wheels 307 is used to align with the side of the fixed platform 101, so that the grinding belt 2 306 can fit the outside of the main metal cover 5, and the fixed rail 309 is as shown in FIG. Figure 1 The invention shows that there are multi-position latch-type fixing points, which is convenient for fixing the longitudinal bracket 308, and starting the drive motor 2 305 to rotate, thereby completing the side drive.

[0071] S2, adjusting the polishing angle: moving the vertical polishing group 2 so that the rotating bottom surface of the grinding wheel belt 1 208 contacts the top surface of the metal cover 5; moving the horizontal polishing group 3 so that the side surface of the grinding wheel belt 2 306 contacts closely with the side surface of the metal cover 5;

[0072] S3, test the polishing effect: start the main motor 103, the vertical polishing group 2, the horizontal polishing group 3, and the transmission platform 4, so that the grinding head 107 and the metal cover 5 are in plane friction, the grinding wheel belt 1 208 and the metal cover 5 are in top surface friction, and the grinding wheel belt 2 306 and the metal cover 5 are in side friction;

[0073] S4, check the pre-polished metal cover 5: set a single main motor 103 rotation node, check the polishing effect of the metal cover 5 after one polishing and in the non-polishing process, and take it out if it is qualified;

[0074] S5, secondary polishing: When step S3 fails, press the metal cover 5 back onto the transmission shaft 104, adjust the oblique movable group 203 to tighten the grinding wheel belt 208 and adjust the close contact relationship between the vertical polishing group 2 and the metal cover 5 for the second time. When the internal polishing of the metal cover 5 fails, adjust the rotation speed of the transmission shaft 2 402 on the transmission platform 4, and then repeat steps S2-S4 until the finished product of S4 is qualified.
