Description

Technical Field

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

[0002] After processing, electromechanical parts need to be polished to meet the technical requirements of smooth surface. Since most electromechanical parts are small in size and large in number, a polishing device composed of a vibrator, a polishing box, an elastic part and other structures is often used. When working, the vibrator drives the polishing box on the elastic part to vibrate, so that the polishing sand contained inside continuously contacts and collides with the electromechanical parts, thereby completing the polishing process.

[0003] However, in actual use, the electromechanical parts are heavier than the polishing sand and will gradually sink to the bottom of the polishing sand during the vibration process, resulting in more contact between the electromechanical parts and less contact between the electromechanical parts and the polishing sand, which will affect the polishing effect and efficiency.

[0004] Therefore, in order to solve the above problems, a polishing device for electromechanical parts is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a polishing device for electromechanical parts, which can increase the contact area between the electromechanical parts and the polishing sand, so as to solve the problems raised in the above-mentioned background technology.

[0007] A polishing device for electromechanical parts comprises a base and a polishing box, wherein elastic parts are evenly fixedly installed between the base and the polishing box, a vibrator is fixedly installed at the center of the lower surface of the polishing box, and a knife gate valve is installed at the bottom of one side of the polishing box through a discharge pipe; a gantry is fixedly installed on the upper surface of the base, a reduction motor is fixedly installed at the center of the upper surface of the gantry, a drive box is fixedly installed at the lower end of the output shaft of the reduction motor, both ends of the drive box are rotatably installed with rotating shafts, one end of each of the rotating shafts is fixedly installed with a dial, the dial is located inside the polishing box and close to the side walls of the polishing box respectively, and a drive assembly for rotating the dial is installed inside the drive box; one end of the dial is located at the front side of the drive box, and the other end of the dial is located at the rear side of the drive box, and the dial is evenly fixedly installed with paddles away from the side wall of the drive box.

[0008] Specifically, the driving assembly includes a double-output shaft motor, a driving bevel gear and a driven bevel gear. The double-output shaft motor is fixedly installed inside the driving box, and the output ends of the double-output shaft motor are fixedly installed with transmission shafts. The ends of the transmission shafts close to the rotating shafts are fixedly installed with driving bevel gears, and the rotating shafts are fixedly installed with driven bevel gears. The driving bevel gears and the driven bevel gears are meshingly assembled.

[0009] Furthermore, the end of the transmission shaft close to the driving bevel gear is rotatably mounted with a bearing seat, and the bearing seat is fixedly assembled with the driving box.

[0010] Specifically, the number of paddles on each of the dials is 2 to 5 and they are evenly distributed around the circumference.

[0011] Furthermore, the paddle is in the shape of an arc-shaped sheet.

[0012] Furthermore, through holes are evenly formed on the dial and the paddle.

[0013] Specifically, the number of the elastic members is 3 to 5 and they are evenly distributed around the circumference.

[0014] Specifically, the elastic member is a cylindrical helical spring.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] See also Figure 1 , Figure 2 and Figure 3 The utility model provides an electromechanical parts polishing device, including a base 1 and a polishing box 7. The base 1 is a rectangular plate-shaped structure, which plays a supporting role. Elastic members 11 are evenly fixedly installed between the base 1 and the polishing box 7. A vibrator 10 is fixedly installed at the center of the lower surface of the polishing box 7. A knife gate valve 19 is installed at the bottom of one side of the polishing box 7 through a discharge pipe; the polishing box 7 is used to hold polishing sand and electromechanical parts. The vibrator 10 and the knife gate valve 19 are existing components. When working, the vibrator 10 makes the polishing box 7 vibrate, driving the polishing sand to rub the electromechanical parts, thereby completing the polishing process. The elastic member 11 can prevent the vibration on the polishing box 7 from being transmitted to the base 1. The knife gate valve 19 can be controlled to discharge the polishing sand and the electromechanical parts at the same time, and the polishing sand and the electromechanical parts are stored separately through a recovery bucket with a filter box.

[0025] A gantry 4 is fixedly installed on the upper surface of the base 1, and a reduction motor 18 is fixedly installed at the center of the upper surface of the gantry 4. A drive box 9 is fixedly installed on the lower end of the output shaft of the reduction motor 18. The gantry 4 is provided with a center hole, and the center hole is used to pass the output shaft of the reduction motor 18. A rotating shaft 8 is rotatably installed on both ends of the drive box 9, and a dial 6 is fixedly installed on one end of each rotating shaft 8. The dial 6 is located inside the polishing box 7 and is close to the side walls of the polishing box 7 respectively. A driving assembly for rotating the dial 6 is installed inside the drive box 9; the driving assembly can rotate the dial 6 in opposite directions at the same time, that is, the dial 6 at the left end rotates clockwise and the dial 6 at the right end rotates counterclockwise when viewed from the front side, and the reduction motor 18 can drive the drive box 9 and the dial 6 to rotate circumferentially, that is, the drive box 9 is counterclockwise when viewed from a top view.

[0026] One end of the dial 6 is located on the front side of the drive box 9, and the other end of the dial 6 is located on the rear side of the drive box 9. The side wall of the dial 6 away from the drive box 9 is evenly fixed with a paddle 5; the rotating dial 6 can drive the paddle 5 to continuously lift the electromechanical accessories and part of the polishing sand at the bottom, and throw them to the center of the polishing box 7 and then sink with the vibration, thereby improving the polishing effect of the electromechanical accessories and avoiding the electromechanical accessories from being deposited at the bottom of the polishing box 7 and affecting the polishing effect.

[0027] Specifically, Figure 3 As shown, the driving assembly includes a double-output shaft motor 12, a driving bevel gear 15 and a driven bevel gear 14. The double-output shaft motor 12 is fixedly installed inside the driving box 9, and the output ends of the double-output shaft motor 12 are fixedly installed with transmission shafts 13, and the ends of the transmission shafts 13 close to the rotating shaft 8 are fixedly installed with driving bevel gears 15, and the rotating shaft 8 is fixedly installed with driven bevel gears 14. The driving bevel gears 15 and the driven bevel gears 14 are meshed and assembled; the double-output shaft motor 12 is an existing component, which can simultaneously rotate the driving bevel gears 15 at both ends, thereby rotating the rotating shaft 8 and the dial 6 in opposite directions.

[0028] Furthermore, the end of the transmission shaft 13 close to the driving bevel gear 15 is rotatably mounted with a bearing seat 16, and the bearing seat 16 is fixedly assembled with the driving box 9; the bearing seat 16 is an existing component composed of a seat body and a bearing and other structures, which supports the transmission shaft 13 and ensures that the driving bevel gear 15 and the driven bevel gear 14 are fully engaged.

[0029] Specifically, the number of paddles 5 on each dial 6 is 2 to 5 and is evenly distributed around the circumference. The configuration is based on the volume of the electromechanical accessories. The smaller the volume of the electromechanical accessories, the greater the number of paddles 5 on each dial 6, ensuring the number of times the dial 6 is lifted when it rotates one circle, thereby avoiding wasting kinetic energy.

[0030] Furthermore, the paddle 5 is in an arc-shaped sheet shape, which can be used to roll up the electromechanical component and throw it to the center of the polishing box 7 to prevent it from slipping during the rolling process.

[0031] Furthermore, through holes 17 are evenly formed on the dial 6 and the paddle 5. The through holes 17 are used to pass polishing sand to reduce the resistance of the dial 6 and the paddle 5 moving in the polishing sand, so that more electromechanical parts are rolled up and less polishing sand is used, thereby fully utilizing kinetic energy.

[0032] Specifically, the number of the elastic members 11 is 3 to 5 and they are evenly distributed around the circumference, playing a role of elastic support for the polishing box 7 . The elastic members 11 are preferably cylindrical helical springs.

[0033] Specifically, the polishing box 7 is bowl-shaped, and the center of the bottom protrudes upward, which can be more compatible with the shape of the dial 6, which is conducive to the mechanical and electrical accessories to slide slowly from the center to the side wall and to be repeatedly rolled up.

[0034] Specifically, a protective tube 2 is fixedly installed on the upper surface of the base 1, and a rubber protective cover 3 is fixedly installed between the protective tube 2 and the polishing box 7. The protective tube 2 and the rubber protective cover 3 can shield and protect the internal elastic part 11 and the vibrator 10 to avoid being corroded by the external environment and extend the service life.

[0035] The working principle of this embodiment:

[0036] The reduction motor 18, the double-shaft motor 12, and the vibrator 10 are electrically connected to an external power source through a controller.

[0037] First, put the electromechanical accessories and polishing sand into the polishing box 7. During operation, the electrical components are energized and work at the same time. The vibrator 10 makes the polishing box 7 on the elastic member 11 vibrate, driving the polishing sand to rub the electromechanical accessories. At the same time, the reduction motor 18 can drive the drive box 9 and the dial 6 to rotate circumferentially. The drive assembly can simultaneously rotate the dial 6 in opposite directions, and the electromechanical accessories at the bottom are continuously pulled up through the paddle 5 to make them fully contact with the polishing sand, and most of the polishing sand can pass through the through hole 17 to reduce the rotation resistance.

[0038] After the polishing process is completed, the power is turned off, and the knife gate valve 19 is opened to discharge the polishing sand and the electromechanical accessories at the same time, and the polishing sand and the electromechanical accessories are stored separately in a recovery bucket with a filter box. The electromechanical accessories are taken out and stored, and the polishing sand can be recycled after storage.
