Description

Technical Field

[0001] This utility model belongs to the field of parts grinding technology, specifically relating to a surface grinding device for metal parts processing. Background Technology

[0002] After rough grinding of the surface of metal parts, a magnetic polishing machine is used to polish and refine the surface of the metal parts. The magnetic polishing machine drives a strong magnet to rotate through a drive device, which in turn drives the magnetic needles in the polishing barrel to rotate at high speed to polish the metal parts. During the polishing process, because the polishing materials and polishing time used for metal parts with different hardness and polishing precision are different, the magnetic polishing machines currently in use are difficult to polish metal parts with different requirements at the same time. In particular, when polishing a small number of metal parts with different requirements, the equipment capacity cannot be fully utilized, resulting in a large amount of waste in the polishing barrel and a significant increase in the processing time.

The drive adjustment sleeve is sleeved on the outer wall of the drive shaft. The four revolution drive rods are evenly fixedly connected to the outer wall of the drive adjustment sleeve. The four drive adjustment sleeves are respectively inserted into the four positioning slots.

[0008] The bottom of each of the four revolution drive rods is provided with a positioning groove, and a limit key is fixedly connected to the outer wall of the drive shaft. The limit key is detachably connected to the drive adjustment sleeve.

[0009] An electric telescopic rod is fixedly connected to the inner wall of the magnetic polishing machine body, and the electric telescopic rod is detachably connected to the positioning groove block.

[0010] The dual rotating toothed disc is equipped with a support ring plate at its bottom end, which is fixedly connected to the inner wall of the magnetic polishing machine body. The dual rotating toothed disc is also equipped with a bottom support plate, which is fixedly connected to the outer wall of the drive shaft.

[0011] The beneficial effects of this utility model are: by using a drive mechanism and an electric telescopic rod to drive and adjust the double rotating toothed disc and the self-rotating drive gear, the four sets of double rotating toothed discs and strong magnetic drive blocks can achieve two rotation methods: revolving around the self-rotating drive gear and rotating around the center of the double rotating toothed disc.

[0018] Please see Figures 1-4The present invention provides the following technical solution: a surface polishing device for processing metal parts, comprising a magnetic polishing machine body 1, a centralized polishing barrel 2 fixedly connected to the top of the magnetic polishing machine body 1, four evenly distributed distinguishing polishing barrels 21 detachably connected to the inner wall of the centralized polishing barrel 2, four evenly distributed double rotating toothed discs 3 provided inside the magnetic polishing machine body 1, four evenly distributed strong magnetic drive blocks 31 embedded at the top of the double rotating toothed discs 3, a self-rotating drive gear 32 meshing at the center of the four double rotating toothed discs 3, and a drive mechanism 4 provided inside the magnetic polishing machine body 1.

[0019] In this implementation scheme: when different parts can be mixed for polishing, the polishing material and parts are directly put into the centralized polishing tank 2. The electric telescopic rod 5 is in a retracted state under the action of the controller and disengages from the positioning slot block 44. The drive adjustment sleeve 42 slides down under the action of gravity and engages with the limit key 45. The drive shaft 41 drives the drive adjustment sleeve 42 to rotate under the action of the drive motor, thereby driving the revolution drive rod 43 to rotate, which in turn drives the double rotating gear disk 3, the strong magnetic drive block 31 and the self-rotating drive gear 32 to revolve synchronously. The strong magnetic drive block 31 drives the magnetic needles inside the centralized polishing tank 2 to polish the parts. When different parts need to be polished separately, the distinguishing polishing tanks 21 are installed in the centralized polishing tank 2. The four distinguishing polishing tanks 21 are respectively connected to four The positions of the double rotating gear disks 3 correspond, and the electric telescopic rod 5 extends under the action of the controller, inserts into the positioning slot 44, and pushes the revolution drive rod 43 upward until the drive adjustment sleeve 42 disengages from the limit key 45. The electric telescopic rod 5 limits the revolution drive rod 43 and further positions the double rotating gear disks 3, so that the double rotating gear disks 3 cannot revolve around the center of the self-rotation drive gear 32. The drive shaft 41 drives the self-rotation drive gear 32 to rotate, thereby driving the four double rotating gear disks 3 to rotate. The drive shaft 41 is connected to a drive motor, which can be a servo motor or a stepper motor, to accurately control the start and stop positions so that the limit key 45 can be accurately inserted into the drive adjustment sleeve 42 and the output shaft of the electric telescopic rod 5 can be accurately inserted into the positioning slot 44.

[0020] A positioning plate 22 is fixedly connected to one side of the distinguishing polishing barrel 21. The positioning plate 22 engages with the side wall of the centralized polishing barrel 2. A positioning pad 23 is fixedly connected to the side wall of the centralized polishing barrel 2. By setting the positioning plate 22, the distinguishing polishing barrel 21 can be installed inside the centralized polishing barrel 2. The positioning pad 23 can increase the contact area with the centralized polishing barrel 2 and improve the stability of the distinguishing polishing barrel 21.

[0021] The bottom of the double rotating gear disk 3 is provided with a positioning slot 33, and an extension connecting sleeve 34 is fixedly connected to the bottom of the double rotating gear disk 3. The position of the extension connecting sleeve 34 corresponds to that of the positioning slot 33. By setting the positioning slot 33 and the extension connecting sleeve 34, it is easy to connect the double rotating gear disk 3 to the revolution drive rod 43, and it will not lose contact with the revolution drive rod 43 when the revolution drive rod 43 moves up and down.

[0022] The drive mechanism 4 includes a drive shaft 41, a drive adjustment sleeve 42, and four revolution drive rods 43. The drive shaft 41 is fixedly connected to the bottom end of the self-rotating drive gear 32. The drive adjustment sleeve 42 is sleeved on the outer wall of the drive shaft 41. The four revolution drive rods 43 are evenly fixedly connected to the outer wall of the drive adjustment sleeve 42. The four drive adjustment sleeves 42 are respectively inserted into four positioning slots 33. Under the action of the drive motor, the drive shaft 41 can drive the self-rotating drive gear 32 and the revolution drive rods 43 to rotate. The drive motor installed at the bottom of the drive shaft 41 is electrically connected to the controller of the magnetic polishing machine body 1.

[0023] Each of the four revolution drive rods 43 has a positioning slot 44 at its bottom end. A limit key 45 is fixedly connected to the outer wall of the drive shaft 41. The limit key 45 is detachably connected to the drive adjustment sleeve 42. The positioning slot 44 facilitates connection with the electric telescopic rod 5, so that the electric telescopic rod 5 can limit the revolution drive rod 43, so that the revolution drive rod 43 will not rotate with the drive shaft 41 after being lifted. The limit key 45 can be connected to the drive adjustment sleeve 42. The electric telescopic rod 5 is electrically connected to the controller of the magnetic polishing machine body 1.

[0024] An electric telescopic rod 5 is fixedly connected to the inner wall of the magnetic polishing machine body 1, and the electric telescopic rod 5 is detachably connected to the positioning groove block 44.

[0025] A support ring plate 6 is installed at the bottom of the double rotating toothed disc 3. The support ring plate 6 is fixedly connected to the inner wall of the magnetic polishing machine body 1. A bottom support plate 61 is installed at the bottom of the double rotating toothed disc 3. The bottom support plate 61 is fixedly connected to the outer wall of the drive shaft 41. The support ring plate 6 and the bottom support plate 61 cooperate to support the double rotating toothed disc 3, so that the horizontal position of the double rotating toothed disc 3 is stable, so as to approach the magnetic needles inside the concentrated polishing barrel 2 and the distinguishing polishing barrel 21.

[0026] The working principle and usage process of this utility model are as follows: When different parts can be mixed for polishing, the polishing material and parts are directly put into the centralized polishing tank 2. The electric telescopic rod 5 is in a retracted state under the action of the controller and disengages from the positioning slot block 44. The drive adjustment sleeve 42 slides down under the action of gravity and engages with the limit key 45. The drive shaft 41 drives the drive adjustment sleeve 42 to rotate under the action of the drive motor, thereby driving the revolution drive rod 43 to rotate, which in turn drives the double rotating gear disk 3, the strong magnetic drive block 31 and the self-rotating drive gear 32 to revolve synchronously. The strong magnetic drive block 31 drives the magnetic needles inside the centralized polishing tank 2 to polish the parts. When parts need to be polished separately, the distinguishing polishing barrel 21 is installed in the centralized polishing barrel 2. The four distinguishing polishing barrels 21 correspond to the positions of the four double rotating gear disks 3 respectively. The electric telescopic rod 5 extends under the action of the controller and enters the positioning slot block 44, and pushes the revolution drive rod 43 upward until the drive adjustment sleeve 42 disengages from the limit key 45. The electric telescopic rod 5 limits the revolution drive rod 43 and further positions the double rotating gear disks 3, so that the double rotating gear disks 3 cannot revolve around the center of the self-rotation drive gear 32. The drive shaft 41 drives the self-rotation drive gear 32 to rotate, thereby driving the four double rotating gear disks 3 to rotate.
