Description

Technical Field

[0001] This utility model relates to the field of CBN grinding wheel processing technology, and in particular to a device for uniformly distributing abrasive grains in CBN grinding wheels. Background Technology

[0002] CBN grinding wheels, also known as cubic boron nitride grinding wheels, have become a core tool in the field of precision grinding due to their high hardness, high thermal stability and chemical inertness to ferrous materials. They are widely used in high-end manufacturing scenarios such as aerospace, automobile manufacturing, and tool grinding, and are especially suitable for high-precision machining of difficult-to-machine materials such as high-speed steel and high-temperature alloys.

[0003] In the preparation process of CBN grinding wheels, the uniform distribution of abrasive grains is a key factor that determines the grinding performance, service life and machining accuracy of the grinding wheel. In the traditional CBN grinding wheel forming process, the mixing of abrasive grains and binders often relies on manual labor or simple stirring devices, which easily leads to abrasive grain agglomeration and uneven distribution. This results in the grinding wheel wearing out too quickly in some areas during use, affecting the surface quality and dimensional accuracy of the machined surface. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a CBN grinding wheel abrasive grain uniform distribution forming device, which aims to improve the problem of uneven abrasive grain distribution when abrasive grains and binders are mixed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CBN grinding wheel abrasive grain uniform distribution forming device, including a mixing chamber, a heat dissipation box fixedly installed at the upper end of the mixing chamber, a mixing assembly included on the inner wall of the heat dissipation box, a driving motor included, one end of the driving motor fixedly installed on the inner wall of the heat dissipation box, a connecting column fixedly connected to the output end of the driving motor, a first bevel gear fixedly connected to the outer wall of the connecting column, a second bevel gear meshing with the tooth end of the first bevel gear, a mixing rod fixedly connected to one end of the second bevel gear, and multiple baffles fixedly installed on the outer wall of the mixing rod.

[0006] The above technical solution utilizes a drive motor to rotate the connecting column. The first bevel gear on the connecting column meshes with the second bevel gear, causing the stirring rod and multiple baffles on the outer wall to rotate within the mixing chamber. During rotation, the baffles can stir and mix the abrasive particles and the binding liquid within the mixing chamber, achieving uniform dispersion of the abrasive particles and improving the surface quality and dimensional accuracy of the processed material.

[0007] Preferably, a screening component is provided at one end of the connecting column. The screening component includes a connecting plate. One side of the connecting plate is fixedly connected to one end of the connecting column. A connecting plate is fixedly installed on the other side of the connecting plate.

[0009] Preferably, the inner wall of the mixing chamber is provided with multiple sliding grooves, and the outer wall of the mixing chamber is provided with a limiting groove.

[0010] Preferably, the outer wall of the connecting column is rotatably connected to the inside of the heat dissipation box, and the outer wall of the stirring rod is rotatably connected to the inside of the stirring chamber.

[0013] Preferably, the outer wall of the screening plate is slidably connected to the inner wall of the mixing chamber, and the inner wall of the screening plate is slidably connected to the outer wall of the mixing rod.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a drive motor is used to drive the connecting column to rotate. The first bevel gear on the connecting column meshes with the second bevel gear to drive the stirring rod and multiple baffles on the outer wall to rotate in the stirring chamber.

[0015] 2. In this utility model, the connecting column drives the connecting disc to rotate synchronously, and the connecting disc drives the limiting column to slide in the limiting groove through the connecting plate.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a CBN grinding wheel abrasive grain uniform distribution forming device, including a mixing chamber 1. A heat dissipation box 2 is fixedly installed at the upper end of the mixing chamber 1. The inner wall of the heat dissipation box 2 includes a mixing assembly 3. The mixing assembly 3 includes a drive motor 301. One end of the drive motor 301 is fixedly installed on the inner wall of the heat dissipation box 2. The output end of the drive motor 301 is fixedly connected to a connecting column 302. A first bevel gear 303 is fixedly connected to the outer wall of the connecting column 302. The tooth end of the first bevel gear 303 is meshed with a second bevel gear 304. One end of the second bevel gear 304 is fixedly connected to a mixing rod 305. Multiple baffles 306 are fixedly installed on the outer wall of the mixing rod 305.

[0020] Specifically, the drive motor 301 drives the connecting column 302 to rotate, and the first bevel gear 303 and the second bevel gear 304 mesh to drive the stirring rod 305 and the multiple baffles 306 on the outer wall to rotate in the stirring chamber 1. This can fully stir and mix the abrasive grains and the bonding liquid, effectively break the abrasive grain agglomeration, achieve uniform dispersion of abrasive grains, and thus improve the grinding performance, service life and processing accuracy of the CBN grinding wheel, and improve the problem of uneven abrasive grain distribution caused by traditional stirring methods.

[0021] Reference Figure 4A screening component 6 is provided at one end of the connecting column 302. The screening component 6 includes a connecting plate 601. One side of the connecting plate 601 is fixedly connected to one end of the connecting column 302. A connecting plate 602 is fixedly installed on the other side of the connecting plate 601. A limiting column 603 is fixedly installed on one side of the connecting plate 602. A screening plate 604 is fixedly installed on the outer wall of the limiting column 603. A plurality of sliders 605 are fixedly installed on the outer wall of the screening plate 604. A spring 606 is fixedly installed on one side of each slider 605.

[0022] Specifically, when the connecting column 302 rotates, it drives the connecting disc 601, the connecting plate 602, and the limiting column 603 to move synchronously. Combined with the sliding of the slider 605 in the groove 7 and the elastic action of the spring 606, the screening plate 604 vibrates, which can accurately screen the abrasive mixture after stirring, separate abrasive particles that are clumped or too large, ensure that the abrasive particles entering the subsequent forming process are uniform in size, ensure the quality of grinding wheel forming, and avoid the situation where the grinding wheel wears too quickly in some areas due to uneven particle size.

[0023] Reference Figure 1 and Figure 2 A feed box 4 is fixedly installed on the outer wall of the mixing chamber 1, and multiple nozzles 5 are fixedly installed on the outer wall of the mixing chamber 1.

[0024] Specifically, the feed box 4 provides a stable feeding channel for the abrasive particles, and multiple nozzles 5 can evenly spray the binding liquid, so that the abrasive particles and the binding liquid can initially and evenly contact each other, laying a good foundation for the full mixing of the subsequent stirring component 3, reducing the initial probability of abrasive particle agglomeration, and improving the overall mixing and forming effect.

[0025] Reference Figure 2 and Figure 4 The inner wall of the mixing chamber 1 is provided with multiple sliding grooves 7, and the outer wall of the mixing chamber 1 is provided with limit grooves 8.

[0026] Specifically, the inner wall of the mixing chamber 1 is provided with a sliding groove 7 and the outer wall is provided with a limiting groove 8, which provides precise guidance and installation space for the movement of the screening component 6, ensures that the slider 605 and the limiting column 603 can slide stably, ensures the smoothness and stability of the screening process of the screening plate 604, avoids the screening effect due to movement deviation, and improves the reliability of the device operation.

[0027] Reference Figure 2 The outer wall of the connecting column 302 is rotatably connected to the inside of the heat dissipation box 2, and the outer wall of the stirring rod 305 is rotatably connected to the inside of the stirring chamber 1.

[0028] Specifically, the connecting column 302 rotates inside the heat dissipation box 2, which ensures that the power of the drive motor 301 is stably transmitted to the first bevel gear 303. At the same time, the heat dissipation box 2 can dissipate the heat generated by the drive motor 301 during operation, preventing the motor from overheating and affecting its working performance. The stirring rod 305 rotates inside the stirring chamber 1, so that the baffles 306 on the outer wall can fully act on the material in the stirring chamber 1, ensuring that the stirring range covers the entire stirring space and improving the uniformity of stirring.

[0029] Reference Figure 2 and Figure 4 The diameter of the limiting post 603 is the same as the width of the limiting groove 8, and the outer wall of the limiting post 603 is slidably connected to the inner side of the limiting groove 8.

[0030] Specifically, the diameter of the limiting post 603 is consistent with the width of the limiting groove 8 and is slidably connected to ensure that the limiting post 603 is accurately guided within the limiting groove 8, avoiding deviation or shaking during the operation of the screening component 6, ensuring the stability of the vibration trajectory of the screening plate 604, thereby improving the screening accuracy and ensuring the consistency of abrasive particle size screening.

[0031] Reference Figure 4 The slider 605 has the same width as the slide groove 7. One side of the slider 605 is slidably connected to the inside of the slide groove 7, and one end of the spring 606 is fixedly installed on the inside of the slide groove 7.

[0032] Specifically, the slider 605 is matched and slidably connected with the groove 7, and one end of the spring 606 is fixed to the inside of the groove 7. On the one hand, it provides stable guidance for the vibration of the screening plate 604, and on the other hand, it uses the elastic deformation of the spring 606 to realize the reciprocating vibration of the screening plate 604, which enhances the vibration screening effect and can separate unqualified abrasive particles more efficiently. At the same time, the buffering effect of the spring 606 can reduce the impact wear between components and improve the operational stability of the device.

[0033] Reference Figure 2 and Figure 4 The outer wall of the screening plate 604 is slidably connected to the inner wall of the mixing chamber 1, and the inner wall of the screening plate 604 is slidably connected to the outer wall of the stirring rod 305.

[0034] Specifically, the outer wall of the screening plate 604 is slidably connected to the inner wall of the mixing chamber 1, and the inner wall is slidably connected to the outer wall of the stirring rod 305. This double sliding fit structure ensures that the screening plate 604 can always maintain a stable relative position with the mixing chamber 1 and the stirring rod 305 during vibration, so that it will not break free from the constraint of the mixing chamber 1 due to vibration, nor will it interfere with the rotation of the stirring rod 305.

[0035] Working principle: Abrasive particles enter the mixing chamber 1 through the feed box 4. The nozzle 5 sprays the bonding liquid into the mixing chamber 1. The drive motor 301 is started, which drives the connecting column 302 to rotate. The connecting column 302 drives the first bevel gear 303 to rotate. The first bevel gear 303 meshes with the second bevel gear 304, which in turn drives the stirring rod 305 to rotate. The stirring rod 305 drives multiple baffles 306 to rotate in the mixing chamber 1, stirring and mixing the abrasive particles and the bonding liquid to achieve uniform dispersion of the abrasive particles. At the same time, the connecting column 302 rotates. When in motion, the connecting plate 601 rotates synchronously. The connecting plate 601 drives the limiting post 603 to slide in the limiting groove 8 through the connecting plate 602. The limiting post 603 drives the screening plate 604 to move. The screening plate 604 drives the slider 605 to slide in the sliding groove 7. During the movement of the slider 605, the spring 606 is compressed or stretched, causing the screening plate 604 to vibrate. The vibrating screening plate 604 screens the abrasive mixture after stirring, separating agglomerated or excessively large abrasive particles to ensure that the abrasive particles in the subsequent forming process have a uniform particle size.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
