Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a polishing device for a screw drill rotor. Background Art

[0002] Grinding and polishing are important steps in the production and processing of screw drill tool rotors. The screw drill tool rotor is fixed by the three-jaw chuck and the tailstock top on the screw drill tool rotor polishing equipment. The three-jaw chuck drives the screw drill tool rotor to rotate. At the same time, the sandpaper belt driven by the motor contacts the screw drill tool rotor to achieve grinding and polishing of the screw drill tool rotor.

[0003] An existing fertilizer drying device for fertilizer production (authorization announcement number CN216245298U) has the following defects: the above-mentioned device sprays coolant on the screw to cool it down when polishing it, and filters the coolant through a first filter component, thereby reusing the coolant. However, the debris generated during the polishing of the screw is mostly tiny debris. The first filter component is a sponge. After the first filter component filters the coolant containing the debris, due to the porous structure of the sponge, the debris is easy to accumulate in the first filter component, which is inconvenient for the staff to clean after polishing, thereby causing the coolant to be blocked in the first filter component, reducing the polishing efficiency. For this reason, we propose the utility model. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Please refer to the attached Figure 1 -Attached Figure 5 A screw drill rotor polishing device comprises a mounting seat 1, wherein a storage cavity 3 is arranged inside the mounting seat 1, a falling groove 2 is arranged on the top surface of the mounting seat 1, a filtering structure is arranged inside the falling groove 2, and the filtering structure comprises a collecting groove 201 arranged on the inner bottom surface of the falling groove 2, a discharge hole 202 is arranged on the inner bottom surface of the collecting groove 201, a filter screen 203 is fixed inside the discharge hole 202, a cross bar 204 is fixed inside the collecting groove 201, an adsorption sleeve 205 is fixed on the outer circumferential wall surface of the cross bar 204, and the adsorption sleeve 205 is made of a magnet material.

[0023] In the embodiment, a fixing hole 206 is provided on the front side of the inner wall of the drop-in slot 2, and an extraction disk 210 is slidably inserted in the fixing hole 206. A cleaning box 207 is slidably provided on the front side of the inner wall of the drop-in slot 2, and a connecting hole 208 is provided on the rear side of the cleaning box 207. A scraping hole 209 is provided on the rear side of the cleaning box 207, and the aperture of the connecting hole 208 is larger than the aperture of the scraping hole 209. One end of the cross bar 204 passes through the connecting hole 208 and the scraping hole 209 and is fixed to one side of the extraction disk 210. By setting the filtering structure, the screw above the mounting seat 1 is polished and punched. During washing, the coolant enters the collecting tank 201 through the falling tank 2. During the falling process, the coolant is washed on the surface of the adsorption sleeve 205. Since the adsorption sleeve 205 is made of magnet material, the adsorption sleeve 205 adsorbs the metal debris in the coolant. After polishing, the staff can extract the cross bar 204 and the adsorption sleeve 205 through the extraction plate 210. During the extraction process, the scraping hole 209 scrapes the metal debris on the surface of the adsorption sleeve 205 into the cleaning box 207, so that the staff can centrally process the filtered metal debris, improve the screw polishing efficiency, and ensure the polishing effect.

[0024] In the embodiment, a mounting frame 4 is slidably provided on the top surface of the mounting seat 1, a screw rod 401 is rotatably provided on one side of the mounting seat 1, a servo motor is fixed on one side of the mounting seat 1, an output shaft of the servo motor is fixed to one end of the screw rod 401, the screw rod 401 is threadedly connected to one side of the mounting frame 4, and a polishing structure is provided inside the mounting frame 4. The staff can drive the screw rod 401 to rotate through the servo motor so that the mounting frame 4 moves back and forth on the top surface of the mounting seat 1, thereby performing polishing along the radial direction of the screw rod.

[0025] In the embodiment, the polishing structure includes a belt polisher 5 arranged inside the mounting frame 4. The belt polisher 5 is a prior art. A fixed frame 501 is fixed on one side of the belt polisher 5. An electric push rod 502 is fixed on the top surface of the fixed frame 501. When the mounting frame 4 moves back and forth on the top surface of the mounting seat 1, the electric push rod 502 drives the fixed frame 501 to rise and fall, so that the belt polisher 5 can grind the screw at a suitable height.

[0026] In the embodiment, a storage box 6 is fixed to the top surface of the mounting frame 4, a water spray pipe 601 is connected and fixed to the bottom surface of the storage box 6, the bottom end of the water spray pipe 601 extends to the inside of the mounting frame 4, a connecting pipe 602 is connected and fixed to the top surface of the storage box 6, the bottom end of the connecting pipe 602 is connected to the storage cavity 3, a water pump is connected and fixed to the bottom end of the connecting pipe 602, the connecting pipe 602 and the water spray pipe 601 are both corrugated hoses, during the grinding process, the water spray pipe 601 sprays coolant on the grinding position, the coolant falls into the storage cavity 3 through the falling groove 2, and the connecting pipe 602 pumps the coolant in the storage cavity 3 into the storage box 6 for recycling.

[0027] During use, a three-jaw chuck 7 is fixed to one side of the mounting seat 1, and the inner bottom surface of the storage cavity 3 is an inclined surface. The three-jaw chuck 7 is a prior art, and one side of the chuck is driven to rotate by a self-installed driving motor. The staff can fix the screw by the three-jaw chuck 7 before polishing. The inclined design of the inner bottom surface of the storage cavity 3 can make the coolant in the storage cavity 3 close to the bottom end of the connecting pipe 602.

[0028] Working principle: During use, the staff first fixes the screw rod through the three-jaw chuck 7, and then drives the screw rod 401 to rotate through the servo motor so that the mounting frame 4 moves back and forth on the top surface of the mounting seat 1. When the mounting frame 4 moves back and forth on the top surface of the mounting seat 1, the electric push rod 502 drives the fixed frame 501 to rise and fall, so that the belt polisher 5 can grind the screw rod at a suitable height. During the grinding process, the water spray pipe 601 sprays the coolant on the grinding position, and the coolant falls into the storage cavity 3 through the drop groove 2. The connecting pipe 602 pumps the coolant in the storage cavity 3 into the storage box 6 for recycling. The screw rod above the mounting seat 1 is polished and punched. During washing, the coolant enters the collecting tank 201 through the falling tank 2. During the falling process, the coolant is washed on the surface of the adsorption sleeve 205. Since the adsorption sleeve 205 is made of magnet material, the adsorption sleeve 205 adsorbs the metal debris in the coolant. After polishing, the staff can extract the cross bar 204 and the adsorption sleeve 205 through the extraction plate 210. During the extraction process, the scraping hole 209 scrapes the metal debris on the surface of the adsorption sleeve 205 into the cleaning box 207, so that the staff can centrally process the filtered metal debris. The inclined design of the bottom surface of the storage cavity 3 can make the coolant in the storage cavity 3 close to the bottom end of the connecting pipe 602.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
