TECHNICAL FIELD
[0001] The utility model relates to grinding device field, especially a kind of grinding device of chamfering of workpiece spill-proof. BACKGROUND
[0002] Neodymium-iron-boron workpiece needs to be chamfered and ground by grinding device before electroplating, to remove sharp corners on workpiece, optimize surface morphology and increase adhesion of electroplated layer.
[0003] When the workpiece of relatively thin and small specification (thickness less than 0.5mm, length and width less than 10mm) is chamfered and ground, some problems may occur. On the one hand, the adhesion of the workpiece may decrease when it is exposed to water, and the workpiece may stick to the inner wall of the grinding device during vibration and fail to tumble, so that the workpiece may spill out of the slot of the grinding device and fall off to be scrapped. On the other hand, the workpieces may be stacked in the slot of the grinding device and break due to collision between them.
[0004] Therefore, the applicant intends to provide a grinding device of chamfering of workpiece spill-proof to solve the above problems. SUMMARY
[0005] The grinding device of chamfering of workpiece spill-proof can prevent the workpiece from spilling out of the slot during grinding, avoid the workpiece from falling off the slot and being scrapped, and guide the workpieces stacked in the slot to tumble towards the center of the slot for further grinding, thereby ensuring the grinding quality and avoiding the workpieces from breaking due to collision.
[0006] To achieve the above purpose, the solution of the utility model is as follows: a grinding device of chamfering of workpiece spill-proof, which comprises a feeding slot and a stirring part. The feeding slot is used to place grinding agents and workpieces, and the stirring part is used to stir the grinding agents and workpieces to grind the chamfer of the workpieces. The grinding device comprises a blocking piece. The slot of the feeding slot is provided with the blocking piece, which extends towards the center of the slot to prevent the workpiece from spilling out of the slot during grinding and guide the workpieces stacked in the slot to tumble towards the center of the slot.
[0007] Further, one end of the blocking piece close to the inner wall of the feeding slot is a bevel, which forms an angle α with the inner wall of the feeding slot, and 90°≤α<180°.
[0008] Further, the blocking piece extends downwards along the inner wall of the feeding slot and closely adheres to the inner wall of the feeding slot, and is hung on the slot of the feeding slot.
[0009] Further, the material of the blocking piece is acrylic.
[0010] After adopting the above solution, the utility model has the following advantages:
[0011] 1、Prevent falling, the workpiece and the grinding piece are placed in the feeding tank, the stirring part stirs the workpiece and the grinding piece, part of the workpiece is taken to the notch of the feeding tank by the grinding piece in the stirring process, because the adhesion of the workpiece decreases when meeting water, the workpiece will stick to the inner wall of the grinding device and cannot roll, because of the strong vibration generated by stirring, the workpiece in these notches is easy to overflow from the notch of the feeding tank. The blocking piece extends to the center of the notch, which is used to prevent the workpiece from overflowing from the notch during grinding.
[0012] 2、Prevent stacking, part of the workpiece is taken to the notch of the feeding tank by the grinding piece in the stirring process, which causes the workpiece to stay in the notch and produce stacking, the stacked workpiece is easy to damage each other and cannot be fully ground due to long-term residence in the notch. The blocking piece extends to the center of the notch, which is used to guide the workpiece stacked in the notch to roll to the center of the notch, ensuring that the workpiece can continue to be ground.

[0024] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the technical solutions in the utility model embodiments will be clearly and completely described below in combination with the drawings in the utility model embodiments. Obviously, the embodiments described below are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0025] The utility model provides a kind of workpiece chamfer anti-overflowing grinding device, and grinding device 2 includes discharge tank 21 and flips stirring part 22, discharge tank 21 is used to place grinding piece 24 and workpiece 3, flips stirring part 22 is used to stir grinding piece 24 and workpiece 3, so that grinding piece 24 grinds chamfer on workpiece 3.
[0026] In the process of grinding workpiece 3, first, grinding piece 24 is placed in discharge tank 21 with workpiece 3. Then, start the whole grinding device 2, and flips stirring part 22 is started immediately, driving grinding piece 24 and workpiece 3 to roll and rub in discharge tank 21. In this process, grinding piece 24 plays its role, effectively removes sharp corners on the surface of workpiece 3, optimizes its surface topography, and thus enhances the adhesion of the plating layer. However, while grinding piece 24 and workpiece 3 rub against each other, part of workpiece 3 is driven by grinding piece 24 to the notch 211 area of discharge tank 21. There are two problems here: referring to Figure 1 A and B, on the one hand, when workpiece 3 encounters water, its adhesion will decrease significantly, causing these workpieces 3 to easily accumulate in notch 211 and stick to inner wall 212. Due to the vibration caused by stirring, these workpieces 3 accumulated in notch 211 are prone to overflow from the edge of notch 211, causing material loss. On the other hand, the workpieces 3 stacked together will knock against each other, which not only damages the surface of workpiece 3, but also makes them unable to be fully ground due to their long-term retention in the notch 211 area, thus reducing the yield of the product.
[0027] A kind of workpiece chamfer anti-overflowing grinding device, including blocking piece 1, the notch 211 of discharge tank 21 is equipped with blocking piece 1. Blocking piece 1 extends to the center of notch 211, blocking workpiece 3, to prevent workpiece 3 from overflowing from notch 211 during grinding. The extended blocking piece 1 guides the workpieces 3 stacked in notch 211 to roll to the center of notch 211, mainly referring to Figure 3 And Figure 7 When workpiece 3 contacts blocking piece 1, blocking piece 1 exerts a downward pressure, and workpiece 3 tilts forward under the pressure of blocking piece 1 and the support force of inner wall 212, falls to the center of notch 211, and thus continues to participate in grinding.
[0028] Mainly referring to Figure 3 And Figure 7The blocking piece 1 is inclined surface 11 near one end of the inner wall 212 of the discharge groove 21, the inclined surface 11 and the inner wall 212 of the discharge groove 21 form an angle α, 90°≤α<180°. When the inclined surface 11 and the inner wall 212 of the discharge groove 21 form an angle α is a right angle or obtuse angle to the best effect of the workpiece 3 guide.
[0029] Mainly refer to Figures 2 to 5 The blocking piece 1 extends along the inner wall 212 of the discharge groove 21, and is close to the inner wall 212 of the discharge groove 21, the blocking piece 1 is hung in the notch 211 of the discharge groove 21. The blocking piece 1 of the first embodiment is designed uniquely, without relying on external objects or external force to be fixed, can easily be hung in the notch 211 of the discharge groove 21 position, installation is simple and also ensures the stability of the blocking piece 1.
[0030] The material of the blocking piece 1 is acrylic. This choice is based on the superior toughness of acrylic material, suitable for grinding device 2. When the workpiece 3 and the acrylic material of the blocking piece 1 contact, the surface of the workpiece 3 will not be damaged due to the good physical properties of acrylic.
[0031] The above only for the preferred embodiment of the present application, not to limit the design of the case, all equivalent changes made in accordance with the design key, fall within the scope of the present application.
