In the related art, a magnetic material blank is roughly ground by a grinding wheel grinding machine, and then the roughly ground magnetic material blank is finely ground by a fine grinding device. During the rough grinding process, the staff needs to hold a magnetic material blank by hand and make it contact with the rotating grinding wheel to achieve grinding. However, this grinding method requires the staff to pick up each magnetic material blank separately, and then bring each magnetic material blank close to the grinding wheel for grinding, which results in a low working efficiency during the rough grinding of the magnetic material blank.

Specific embodiments

[0025] The following will further elaborate on the present application in conjunction with the attached Figures 1-4 drawings.

[0026] The embodiment of the present application discloses a magnetic material blank grinding device. Referring to Figure 1 , the magnetic material blank grinding device includes a base 1, a grinding mechanism 2 and a clamping mechanism 3. The grinding mechanism 2 and the clamping mechanism 3 are both installed on the top of the base 1, and the grinding mechanism 2 and the clamping mechanism 3 are arranged at intervals. The clamping mechanism 3 is slidably installed on the base 1, and the clamping mechanism 3 moves closer to or away from the grinding mechanism 2. The clamping mechanism 3 can clamp multiple magnetic material blank parts at a time, so that the grinding mechanism 2 can rough grind multiple magnetic material blank parts at a time, thereby improving the working efficiency during the rough grinding of the magnetic material blank parts.

[0027] Referring to Figure 1 and Figure 2 , the grinding mechanism 2 includes a mounting frame 21, a grinding sand belt 22 and a driving motor 23. The mounting frame 21 is installed on the top of the base 1 through high-strength bolts. Two transmission shafts are rotatably installed on the mounting frame 21. The two transmission shafts are arranged at intervals in the vertical direction on the mounting frame 21. An annular belt is sleeved on the two transmission shafts, and the two transmission shafts are synchronously rotated through the annular belt. The grinding sand belt 22 is an annular shape, and the grinding sand belt 22 is sleeved on the two transmission shafts. The grinding sand belt 22 can rotate under the action of the two transmission shafts. The side of the grinding sand belt 22 close to the clamping mechanism 3 protrudes from the mounting frame 21, so as to grind the magnetic material blank parts. The driving motor 23 is installed on the mounting frame 21 to drive one of the transmission shafts to rotate.

[0028] Referring to Figure 1 and Figure 3, the clamping mechanism 3 includes a mobile cabinet 31, a clamping assembly 32, and a vertical screw 33. An installation groove 311 is formed on one side of the mobile cabinet 31 close to the grinding sand belt 22. The clamping assembly 32 is installed in the installation groove 311 for clamping the magnetic material blank. There are multiple groups of the clamping assembly 32, and multiple groups are arranged at intervals along the vertical direction in the installation groove 311. The mobile cabinet 31 drives multiple groups of the clamping assembly 32 to slide on the base 1. The vertical screw 33 is rotatably installed on the mobile cabinet 31 and is used to drive multiple groups of the clamping assembly 32 to clamp or release synchronously.

[0029] A dovetail block 312 is welded to the bottom of the mobile cabinet 31. A sliding groove 11 for the dovetail block 312 to insert and slide is formed on the outer wall of the base 1 on the side close to the installation frame 21 along the sliding direction of the mobile cabinet 31, and the sliding groove 11 does not penetrate the base 1. A transverse screw 12 is inserted and rotatably installed on the outer wall of the base 1 on the side opposite to the dovetail groove. One end of the transverse screw 12 away from the dovetail groove of the base 1 protrudes from the base 1 and is welded with a rotating handwheel 13; one end of the transverse screw 12 away from the rotating handwheel 13 passes through the dovetail block 312 and extends towards the notch of the dovetail groove. The dovetail block 312 is threadedly connected with the transverse screw 12, so that the mobile cabinet 31 can be driven to move when the transverse screw 12 rotates.

[0030] The structures of multiple groups of the clamping assembly 32 are the same. Here, one group of the clamping assembly 32 is taken as an example for elaboration.

[0031] Refer to Figure 3 and Figure 4 , the clamping assembly 32 includes a fixed plate 34, a movable clamping plate 35, and a guide rail group 36. The fixed plate 34 is welded to the groove wall of the installation groove 311. The movable clamping plate 35 is located above the fixed plate 34, and the movable clamping plate 35 moves directionally closer to or away from the movable clamping plate 35 under the cooperation of the guide rail group 36.

[0032] There are two groups of the guide rail group 36. The two groups of the guide rail group 36 are respectively installed on two opposite groove walls of the installation groove 311, and the opposite ends of the movable clamping plate 35 are respectively installed on the two guide rail groups 36. The guide rail group 36 includes a linear guide rail and a slider. The linear guide rail is installed on the groove wall of the installation groove 311 through bolts. The slider is connected with the movable clamping plate 35 through bolts, and the slider slides directionally on the linear guide rail, thereby driving the movable clamping plate 35 to slide directionally.

[0033] Refer to Figure 3 and Figure 4, a butt plate 37 is welded below the lowermost fixing plate 34 among the multiple fixing plates 34. The bottom of the vertical screw rod 33 passes through the multiple fixing plates 34 and the movable clamping plates 35 in multiple groups of clamping assemblies 32 in sequence and is rotatably installed on the butt plate 37. The movable clamping plate 35 is sleeved and threadedly installed on the vertical screw rod 33, and the fixing plate 34 is sleeved on the vertical screw rod 33. The fixing plate 34 and the vertical screw rod 33 are in clearance fit, so that when the vertical screw rod 33 rotates, the movable clamping plate 35 can move in the vertical direction, and the fixing plate 34 does not interfere with the vertical screw rod 33.

[0034] The top of the vertical screw rod 33 protrudes from the movable cabinet 31, and a driving handwheel 331 is welded to the top of the vertical screw rod 33, making it more convenient to drive the vertical screw rod 33 to rotate.

[0035] Refer to Figure 3 With Figure 4 , a first rubber pad 38 is pasted on one side of the fixing plate 34 close to the movable clamping plate 35; a second rubber pad 39 is pasted on one side of the movable clamping plate 35 close to the fixing plate 34. When the movable clamping plate 35 and the fixing plate 34 clamp the magnetic material blank, the first rubber pad 38 and the second rubber pad 39 can protect the surface of the magnetic material blank to be polished, so that the surface after polishing is not easily scratched or marked when being clamped. Correspondingly, the vertical screw rod 33 also passes through the first rubber pad 38 and the second rubber pad 39 and is in clearance fit with the first rubber pad 38 and the second rubber pad 39.

[0036] The implementation principle of a magnetic material blank grinding device in an embodiment of the present application is as follows: when rough grinding a magnetic material blank, multiple magnetic material blanks can be respectively placed on multiple fixing plates 34, and the surface of the magnetic material blank to be polished protrudes from the movable cabinet 31. Then, rotate the driving handwheel 331 to drive the vertical screw rod 33 to rotate. After the vertical screw rod 33 rotates, the multiple movable clamping plates 35 move in the direction close to the fixing plate 34 under the limitation of their respective corresponding guide rail groups 36 and clamp the magnetic material blanks. Then, the operator rotates the handwheel 13 to drive the horizontal screw rod 12 to rotate, so that the movable cabinet 31 moves in the direction close to the grinding sand belt 22, and the planes of the multiple magnetic material blanks to be polished are in contact with the surface of the grinding sand belt 22 to realize grinding. The above structure can grind multiple magnetic material blanks at one time, thereby improving the working efficiency during the rough grinding of magnetic material blanks.

[0037] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
