Detailed implementation mode

[0028] The present invention will be specifically described below in conjunction with the accompanying drawings, as Figures 1-11 shown: A magnetic polishing device for a bearing cage includes a magnetic polishing machine 1 and a turnover rack 2 located at the front end of the magnetic polishing machine 1. A table corresponding to the grid-type bearing frame 4 is provided on the magnetic polishing machine 1. A collection tank 3 is arranged on the right side of the turnover rack 2. The turnover rack 2 is connected with a grid-type bearing frame 4 through a turnover mechanism; the turnover mechanism includes a driving cylinder 5 horizontally installed on the left side of the bottom of the turnover rack 2. A sliding table 6 is slidably installed on the turnover rack 2, and the bottom of the sliding table 6 is connected with the telescopic end of the driving cylinder 5. A turnover rod 7 is movably inserted on the sliding table 6 through a fastening bearing. The right end of the turnover rod 7 is connected with the grid-type bearing frame 4. An arc-shaped top shell 8 is installed on the top of the turnover rack 2. A turnover guide groove 9 is opened in the arc-shaped top shell 8. The left end of the turnover rod 7 is slidably installed in the turnover guide groove 9 through a circular slider 10, as Figure 5 and Figure 6 shown. The turnover guide groove 9 is used to guide the turnover rod 7. When the sliding table 6 moves to the right, the turnover rod 7 drives the grid-type bearing frame 4 to first move horizontally away from the table of the magnetic polishing machine 1, and then turn 180° to achieve automatic turnover.

[0029] The divided carrying frame 4 is provided with an equal division mechanism. The equal division mechanism includes a group of horizontal fixing plates 11 and several vertical adjusting plates 12 installed in the divided carrying frame 4. By placing the bearing cages to be magnetically polished in a divided manner, it is possible to prevent the bearing cages from being damaged by collision during the magnetic polishing process.

[0030] A collection box 13 is placed in the collection tank 3. After the bearing cage is turned over, it falls into the collection box in the collection tank, which is convenient for flushing the metal impurities attached to the surface.

[0031] The turning frame 2 is provided with a strip-shaped hole 14. The telescopic end of the driving cylinder 5 is connected to the sliding table 6 through a connecting plate 15, and the connecting plate 15 is located in the strip-shaped hole 14, which facilitates the movement of the sliding table 6 on the turning frame 2.

[0032] A group of side plates 16 are installed on both sides of the rear end of the divided carrying frame 4. A group of fixed round rods 17 are installed between the group of side plates 16. A number of adjusting plates 18 are movably sleeved on the group of fixed round rods 17. The number of adjusting plates 18 are arranged at equal intervals, and the front ends of the number of adjusting plates 18 are respectively connected to the corresponding vertical adjusting plates 12; a servo cylinder 19 is horizontally installed on the right side plate 16, and the telescopic end of the servo cylinder 19 is connected to the right adjusting plate 18; the tops of the number of adjusting plates 18 are connected through a diamond-shaped telescopic frame 20, and the left end of the diamond-shaped telescopic frame 20 is fixed on the left side plate 16. As Figure 3 shown, when the servo cylinder 19 expands and contracts, it can drive a number of vertical adjusting plates 12 to be adjusted at equal intervals through the right adjusting plate 18 and the diamond-shaped telescopic frame 20, so that the divided carrying frame 4 can be adjusted according to the size of the bearing cage; A number of vertical adjusting plates 12 are respectively provided with notches 21 corresponding to a group of horizontal fixing plates 11. As Figure 7 shown, it is convenient for the vertical adjusting plates 12 to move and for the divided carrying frame 4 to be divided.

A group of bottom covers 25 are hinged to the bottom of the collection box 3. A group of electric push rods 26 are hinged to both sides of the collection box 3, and the telescopic ends of the group of electric push rods 26 are respectively hinged to the rear ends of the corresponding bottom covers 25. A group of hanging rings 27 are installed on both sides of the upper end of the collection box 3. As Figure 9 — Figure 11As shown, the turned-over bearing cage falls into the collection box 13 in the collection tank 3. The sieve-shaped holes 23 on the partition plate 22 are used to filter the polishing liquid and magnetic needles. The bearing cage falls on the partition plate 22, which is convenient for flushing the metal impurities attached to the surface. The water seepage holes 24 are used to drain the polishing liquid. The magnetic needles fall on the bottom of the collection box 13. The collection box 13 is lifted out by an external overhead crane. The telescopic ends of a group of electric push rods 26 contract, driving a group of bottom covers 25 to open automatically, facilitating the recovery of the magnetic needles.

[0034] Working principle of this implementation scheme: The electrical equipment used in this device is controlled by an external controller. The initial position of the grid-shaped bearing frame 4 is on the table surface of the magnetic polishing machine 1; During equal division: First, the user adjusts the grid-shaped bearing frame 4 according to the size of the bearing cage. The servo cylinder 19 expands and contracts, and can drive a number of adjusting plates 18 to be adjusted equidistantly through the right adjusting plate 18 and the diamond-shaped telescopic frame 20. A number of adjusting plates 18 drive a number of vertical adjusting plates 12 to cooperate with a group of horizontal fixing plates 11 to realize the slot adjustment of the grid-shaped bearing frame 4. The bearing cages that need magnetic polishing are respectively placed in the equally divided slots in the grid-shaped bearing frame 4, and appropriate amounts of magnetic needles and polishing agents are respectively added. Since a group of horizontal fixing plates 11 are fixedly arranged, the grid-shaped bearing frame 4 can be maximally equally divided into a number of square slots. By placing the bearing cages that need magnetic polishing in a grid pattern, it can prevent the bearing cages from colliding and being damaged during the magnetic polishing process, and the size of the slots can be adjusted, with higher applicability; During turning: After the magnetic polishing of the bearing cage is completed, the telescopic end of the driving cylinder 5 extends. Through the connecting plate 15, it drives the sliding table 6 to move to the right. The turning guide groove 9 is used to guide the turning rod 7. When the sliding table 6 moves to the right, first, the turning rod 7 drives the grid-shaped bearing frame 4 to move horizontally away from the table surface of the magnetic polishing machine 1. Then, through the turning guide groove 9, it realizes a 180° flip to achieve automatic turning. The turned-over bearing cage falls into the collection box 13 in the collection tank 3. Then, the telescopic end of the driving cylinder 5 contracts, driving the grid-shaped bearing frame 4 to reset; During collection: The turned-over bearing cage falls into the collection box 13 in the collection tank 3. The sieve-shaped holes 23 on the partition plate 22 are used to filter the polishing liquid and magnetic needles. The bearing cage falls on the partition plate 22, which is convenient for flushing the metal impurities attached to the surface. The water seepage holes 24 are used to drain the polishing liquid. The magnetic needles fall on the bottom of the collection box 13. The collection box 13 is lifted out by an external overhead crane. The telescopic ends of a group of electric push rods 26 contract, driving a group of bottom covers 25 to open automatically, facilitating the recovery of the magnetic needles.
