Description

Technical Field

[0001] This utility model belongs to the technical field of stirring devices, and in particular relates to a stirring device for uniformly mixing micro powder abrasive and grinding fluid. Background Technology

[0002] After the initial processing of bearing steel balls, such as cold heading, light grinding, soft grinding heat treatment, and hard grinding, their diameter is only 0.25~0.275mm away from the finished diameter. They must undergo further processing to improve their roundness and roughness, including primary grinding (hereinafter referred to as primary grinding) and fine grinding (hereinafter referred to as fine grinding), in order to meet the process requirements.

[0003] The abrasive powder used for initial and fine grinding must be uniformly mixed with the grinding fluid. At the same time, it is important to prevent impurities and large particles from being mixed into the powder. The presence of impurities and large particles will cause severe wear on the surface of the bearing steel balls during the grinding process. The existing abrasive powder and grinding fluid do not have corresponding measures to treat impurities and large particles during the uniform mixing process, which increases the risk of damage to the bearing steel balls in the subsequent grinding process. Utility Model Content

[0004] This invention provides a device for uniformly mixing micro-powder abrasive and grinding fluid, aiming to solve the problem that existing methods for uniformly mixing micro-powder abrasive and grinding fluid lack corresponding means for treating impurities and large particles, which increases the risk of damage to bearing steel balls in the subsequent grinding process.

[0005] This invention is achieved by a device for uniformly mixing and stirring micro-powder abrasive and grinding fluid, comprising:

[0006] A mixing tank, the top of which is an open structure, is used to place micro-powder abrasive and grinding fluid to be mixed.

[0007] A stirring unit, comprising a stirring motor, a support bracket, and a stirring shaft, wherein the stirring motor is mounted on the top of the mixing tank via the support bracket, and the stirring shaft connected to the motor shaft of the stirring motor is provided with stirring blades, and the stirring shaft extends into the interior of the mixing tank;

[0008] The grinding unit is located at the bottom of the mixing tank. The grinding unit contains grinding balls for grinding. The stirring shaft is also equipped with a stirring element that extends into the grinding unit. When the stirring blades rotate, the stirring element pushes the grinding balls to squeeze and grind each other inside the grinding unit.

[0009] Preferably, the grinding unit includes an outer ring platform, an upper partition plate, and an inner bottom ring. The upper partition plate is connected to the end face of the outer ring platform away from the bottom of the mixing tank. The outer ring platform is provided with the outer ring side of the inner bottom ring. The grinding balls fill the annular cavity formed by the outer ring platform, the upper partition plate, and the inner bottom ring.

[0010] Preferably, the inner edge of the upper partition is further provided with an inner ring plate, the inner ring plate having the same diameter as the inner bottom ring, and the bottom surface of the inner ring plate and the top surface of the inner bottom ring being spaced apart to form mixing gaps, the stirring element extending from the mixing gaps into the annular cavity.

[0011] Preferably, the stirring component includes a disc and mixing blades arranged in a ring array around the disc.

[0012] Preferably, the upper partition plate is provided with a plurality of sieve holes for accommodating the flow of micro-powder abrasive and grinding fluid.

[0013] Preferably, the diameter of the sieve holes is smaller than the diameter of the grinding balls filling the annular cavity.

[0014] Preferably, the width of the mixing gap is smaller than the diameter of the grinding ball.

[0015] Preferably, the stirring element is located at the end of the stirring shaft, the disc is connected to the stirring shaft, and the stirring blades are located in the middle section of the stirring shaft.

[0016] Preferably, the inner wall of the outer ring platform has an inclined surface structure.

[0017] Compared with the prior art, the embodiments of this application have the following main advantages:

[0018] The micro-powder abrasive and grinding fluid uniform mixing and stirring device provided by this utility model uses an annular cavity formed by an outer ring platform, an upper partition plate, and an inner bottom ring. During the mixing and stirring process, large particles in the micro-powder abrasive and grinding fluid will be deposited into the annular cavity under the action of gravity. The grinding balls located in the annular cavity will collide with each other under the stirring of the stirring component. Impurities and large particles will disintegrate and break down during the collision of the steel balls, which greatly reduces the content of large particles in the mixture of micro-powder abrasive and grinding fluid, and reduces the damage of impurities and large particles in the subsequent mixture to the bearing steel balls.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] This utility model provides a device for uniformly mixing and stirring micro-powder abrasive and grinding fluid, such as... Figures 1-5 As shown, the device for uniformly mixing and stirring micro-powder abrasive and grinding fluid includes:

[0029] A mixing tank 100, the top of which is an open structure, is used to place micro-powder abrasive and grinding fluid to be mixed.

[0030] The stirring unit 200 includes a stirring motor 210, a support bracket 220, and a stirring shaft 230. The stirring motor 210 is mounted on the top of the mixing tank 100 via the support bracket 220. The stirring shaft 230, which is connected to the motor shaft of the stirring motor 210, is provided with stirring blades 240. The stirring shaft 230 extends into the interior of the mixing tank 100.

[0031] A grinding unit 300 is disposed at the bottom of a mixing tank 100. The grinding unit 300 is provided with grinding balls 340 for grinding inside. A stirring element 250 is also provided on the stirring shaft 230. The stirring element 250 extends into the interior of the grinding unit 300. When the stirring blade 240 rotates, the stirring element 250 pushes the grinding balls 340 to squeeze and grind each other inside the grinding unit 300.

[0032] In this embodiment, the grinding unit 300 includes an outer ring platform 310, an upper partition plate 320, and an inner bottom ring 330. The upper partition plate 320 is connected to the end face of the outer ring platform 310 away from the bottom of the mixing tank 100. The outer ring platform 310 is provided with the outer ring side of the inner bottom ring 330. The grinding balls 340 fill the annular cavity formed by the outer ring platform 310, the upper partition plate 320, and the inner bottom ring 330. This annular cavity is located at the bottom of the mixing tank 100. During the mixing and stirring process, large particles in the micro-powder abrasive and grinding fluid will be deposited into the annular cavity under the action of gravity. The grinding balls 340 located in the annular cavity will collide with each other under the stirring of the stirring element 250. The large particles will disintegrate and break during the collision of the steel balls, reducing the content of large particles in the mixture of micro-powder abrasive and grinding fluid, and reducing the wear of the workpiece by the subsequent mixture.

[0033] In a preferred embodiment of this invention, the inner edge of the upper partition 320 is further provided with an inner ring plate. The inner ring plate has the same diameter as the inner bottom ring 330. The bottom surface of the inner ring plate and the top surface of the inner bottom ring 330 are spaced apart to form mixing gaps. The stirring element 250 extends from the mixing gap into the annular cavity. The width of the mixing gap is smaller than the diameter of the grinding ball 340.

[0034] In this embodiment, the upper partition plate 320 is provided with numerous sieve holes to accommodate the flow of micro-powder abrasive and grinding fluid. The diameter of the sieve holes is smaller than the diameter of the grinding balls 340 filled in the annular cavity. The grinding balls 340 will not leave the annular cavity from the sieve holes and the mixing gaps. The inner wall of the outer ring platform 310 is a sloping structure. The sloping inner wall of the outer ring platform 310 mainly reduces grinding dead angles and prevents large particles from accumulating in dead angles and failing to contact the steel balls, thus failing to achieve the grinding purpose.

[0035] In a preferred embodiment of this invention, the stirring element 250 includes a disc and a mixing blades arranged in a ring array around the disc. The stirring element 250 is located at the end of the stirring shaft 230, the disc is connected to the stirring shaft 230, and the stirring blades 240 are located in the middle section of the stirring shaft 230. The stirring element 250 includes a disc and a mixing blades arranged in a ring array around the disc.

[0036] In this application, the stirring motor 210 is a prior art structure and will not be described in detail. The stirring motor 210 is connected to the support bracket 220 through a motor support. The support bracket 220 can be a trapezoidal support frame. The support bracket 220 has slots at both ends. The two ends of the support bracket 220 are engaged with the side wall of the mixing tank 100. Locking bolts are provided on the outside of the slots of the support bracket 220. As the locking bolts are screwed in and extended into the slots, the locking bolts will abut against the side wall of the mixing tank 100 inserted into the slots to complete the limiting and locking. In addition to the above method, the support bracket 220 can also be replaced by other structures.

[0037] The stirring blades 240 act within the mixing tank 100, allowing the micro-powder abrasive and grinding fluid to mix thoroughly under stirring. The stirring element 250 utilizes a disc to enhance the strength of the mixing blades, which extend from the mixing gap into the annular cavity. The stirring shaft 230 is movably connected to the stirring motor 210. During disassembly, the stirring shaft 230 is first separated from the stirring motor 210, then the connection between the support bracket 220 and the mixing tank 100 is removed, and finally the upper partition 320 is removed to take out the stirring shaft 230 and the grinding balls 340.
