Description

Technical Field

[0001] This utility model relates to the field of grinding, specifically to a grinding device for alloy parts. Background Technology

[0002] In traditional machining processes, rough grinding and fine grinding are two crucial steps. Rough grinding primarily removes excess material, while fine grinding further smooths the part's surface and achieves the required precision. However, when fine grinding follows rough grinding, particles generated during the rough grinding process adhere to the part's surface, negatively impacting the fine grinding effect. These particles accelerate wheel wear during fine grinding, reducing wheel life, and also leave scratches or pits on the part's surface, affecting its smoothness and overall quality.

[0003] According to publicly available patent CN221984739U, a grinding device for mechanical parts is disclosed. This utility model provides such a grinding device for mechanical parts, including a base frame, a motor, a turntable, a lifting mechanism, a coarse grinder, a fine grinder, and a flushing mechanism. The motor is located at the bottom of the base frame, with its output shaft facing upwards and fixed to the turntable. The lifting mechanism is located at the top of the base frame, above the turntable. The coarse grinder and fine grinder are located below the lifting mechanism, at the front and rear ends of the base frame, respectively. The flushing mechanism is mounted on the base frame. This utility model, by incorporating a flushing mechanism, allows for water rinsing of the parts after coarse grinding, effectively improving the removal efficiency of particles adhering to the surface of the parts, while simultaneously reducing surface damage and improving grinding quality. This provides a new solution for improving the processing quality and efficiency of mechanical parts.

[0004] However, in traditional alloy parts grinding equipment, after completing the rough grinding process, a rinsing assembly is used to rinse the workpiece surface. This rinsing method requires a dedicated rinsing pipe, and because the workpiece position is not fixed, the rinsing position of the pipe must be adjusted according to the different workpiece positions, making it cumbersome. Furthermore, during the grinding process, the grinding disc continuously rubs against the workpiece, generating a large amount of heat. If this heat cannot be dissipated in time, it can easily cause the grinding disc to overheat and become damaged. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an alloy parts grinding device to solve the problem that the current traditional alloy parts grinding devices use a rinsing component to rinse the workpiece surface after completing the rough grinding process. However, this rinsing method not only requires a special rinsing pipe, but also requires adjusting the rinsing position of the pipe according to the different positions of the workpiece since the workpiece position is not fixed, which is cumbersome to operate. At the same time, during the grinding process, the grinding disc will continuously rub against the workpiece, thereby generating a lot of heat. If the heat cannot be dissipated in time, it is easy to cause the grinding disc to be damaged due to overheating.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A grinding device for alloy parts is designed, including a device base box. One end of a support rod is fixed to each of the four corners of the top of the device base box. A device top plate is fixed to the other end of the support rod. A first fixing plate and a second fixing plate are fixed to the bottom sides of the device top plate, respectively. A first drive motor is installed on the side of the first fixing plate. The output shaft of the first drive motor passes through the first fixing plate and is connected to a threaded rod via a coupling. A movable block passes through the outside of the threaded rod, and a threaded hole in the movable block connects to the threaded rod. A telescopic cylinder is installed at the bottom of the movable block, and a grinding assembly is provided at the bottom of the telescopic cylinder.

[0007] Preferably, the grinding assembly includes a water tank, with pump bodies connected to both sides of the water tank, and a first connecting pipe connected to one end of the pump body, which is connected to a stationary ring inside the rotary joint.

[0008] Preferably, the rotating ring at the other end of the rotary joint is connected to the second connecting tube, one end of the second connecting tube passes through the first gear, and the penetration position of the first gear and the second connecting tube is fixed.

[0009] Preferably, the end of the second connecting pipe away from the rotary joint is connected to a circular nozzle, the surface of which is provided with multiple spray holes, and an annular grinding disc is detachably installed on its exterior.

[0010] Preferably, a dual-shaft motor is installed at the bottom of the water tank. The output shafts at both ends of the dual-shaft motor are connected to rotating rods via couplings. A second gear is fixed at one end of the rotating rod, and a first gear meshes with the top of the second gear.

[0011] Preferably, the top and front end of the water tank are both connected to one end of a water pipe, and the other end of the water pipe is detachably connected to a pipe cover.

[0012] Preferably, the bottom of the telescopic cylinder is provided with an installation groove, and a second drive motor is installed inside the installation groove. The output shaft of the second drive motor is fixed with a water tank.

[0013] Preferably, a limiting rod extends through the top of the movable block, and a first fixing plate and a second fixing plate are fixed at both ends of the limiting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model combines a threaded rod, a telescopic cylinder, and a grinding assembly. Because it is equipped with both a coarse grinding disc and a fine grinding disc, it allows for switching between coarse and fine grinding of the workpiece, providing multiple grinding modes. Furthermore, during the grinding process, a dual-axis motor drives the nozzle and grinding disc to rotate. While the grinding disc rotates and grinds the workpiece, the nozzle continuously sprays water to rinse the surface of the workpiece. By integrating the rinsing mechanism with the grinding mechanism, there is no need for additional rinsing pipes or adjustments to their positions. This solves the problem of traditional alloy parts grinding devices that, after coarse grinding, use a rinsing assembly to rinse the workpiece surface. However, this rinsing method requires additional rinsing pipes and, because the workpiece position is not fixed, necessitates adjusting the rinsing position of the pipes according to the different workpiece positions, making operation cumbersome.

[0016] 2. This utility model combines a circular nozzle and an annular grinding disc. The annular grinding disc is installed on the outside of the circular nozzle. When the circular nozzle continuously sprays water, the inner wall of the annular grinding disc comes into contact with the outer wall of the nozzle. During this process, heat can be conducted between the two. With the help of the continuously flowing water inside the nozzle, heat exchange is achieved on the annular grinding disc, thereby directly reducing the temperature of the annular grinding disc. This solves the technical problem that during the grinding process, the grinding disc will continuously rub against the workpiece, generating a large amount of heat. If the heat cannot be dissipated in time, it will easily lead to damage to the grinding disc due to overheating. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A grinding apparatus for alloy parts, see [link / reference] Figures 1 to 3The device includes a base box 1. Support rods 101 are fixed to one end of each of the four corners of the top of the base box 1. A top plate 102 is fixed to the other end of each support rod 101. A first fixing plate 2 and a second fixing plate 202 are fixed to the bottom sides of the top plate 102, respectively. A first drive motor 201 is mounted on the side of the first fixing plate 2. The output shaft of the first drive motor 201 passes through the first fixing plate 2 and is connected to a threaded rod 203 via a coupling. A moving block 204 passes through the outside of the threaded rod 203. A threaded hole in the moving block 204 connects to the threaded rod 203. A telescopic cylinder 205 is mounted at the bottom of the moving block 204. A grinding assembly is located at the bottom of the telescopic cylinder 205. First, the alloy parts to be processed are placed in the base box 1. At the top, the component is clamped by a clamping assembly to ensure that the position of the component is fixed and will not shift during subsequent processing, providing a foundation for grinding. After clamping is completed, the first drive motor 201 is started. The first drive motor 201 drives the threaded rod 203 to rotate. Since the moving block 204 is threadedly engaged with the threaded rod 203, the rotation of the threaded rod 203 is converted into the linear movement of the moving block 204. During the movement, the moving block 204 will synchronously drive the telescopic cylinder 205 and the water tank 206 to move together. The movement of the water tank 206 further drives the annular grinding discs 213 on both sides to move, gradually bringing them closer to the grinding position. When the annular grinding discs 213 move to the appropriate grinding position, the telescopic cylinder 205 is started.The telescopic cylinder 205 extends downward, pushing the annular grinding disc 213 downward until it contacts the surface of the alloy part, preparing for the grinding operation. During the downward movement of the annular grinding disc 213, the dual-axis motor 214 is simultaneously activated. The dual-axis motor 214 drives the rotating rod 215 to rotate, which transmits power to the second gear 212. The second gear 212 meshes with the first gear 211, thereby driving the first gear 211 to rotate. The first gear 211 is connected to the second connecting pipe 217. 17. Rotary connection is achieved through the rotating ring of rotary joint 210. Therefore, the rotation of the first gear 211 will drive the second connecting pipe 217 to rotate. The second connecting pipe 217 is connected to the circular nozzle 218 and the annular grinding disc 213, which in turn drives the circular nozzle 218 and the annular grinding disc 213 to rotate together. At this time, the annular grinding disc 213 begins to grind the surface of the alloy parts to remove excess material and achieve the required processing accuracy and surface quality. During the grinding process, the pump body 209 is started, and the pump body 209 pumps water from the water tank 206. The water is fed through the first connecting pipe 216 to the rotary joint 210. The design of the rotary joint 210 allows the water to pass smoothly through the second connecting pipe 217 while it rotates. After entering the second connecting pipe 217, the water is then fed into the circular nozzle 218. The circular nozzle 218 has multiple nozzle holes 219 on its surface. The water is sprayed out from the nozzle holes 219, forming a water flow with a certain pressure, which is sprayed directly onto the surface of the workpiece being ground. The water flow can wash away the debris, dust and other impurities generated during the grinding process in time, preventing impurities from accumulating in the grinding area and affecting the grinding effect and the surface quality of the parts. At the same time, the water flow can also play a certain cooling role, reducing the temperature of the grinding area and reducing problems such as part deformation and grinding disc wear caused by high temperature. This solves the problem that traditional alloy parts grinding equipment uses a flushing component to flush the workpiece surface after the rough grinding process. However, this flushing method not only requires a special flushing pipe, but also requires adjusting the flushing position of the pipe according to the different positions of the workpiece, which is a relatively cumbersome technical problem.

[0023] For details, see Figure 2 The grinding assembly includes a water tank 206, with pump bodies 209 connected to both sides of the water tank 206. One end of the pump body 209 is connected to a first connecting pipe 216, which is connected to the stationary ring inside the rotary joint 210.

[0024] For more details, see Figure 2 The rotating ring at the other end of the rotary joint 210 is connected to the second connecting tube 217. One end of the second connecting tube 217 passes through the first gear 211, and the through position of the first gear 211 and the second connecting tube 217 is fixed.

[0025] Further, see Figure 2 The second connecting pipe 217, away from the rotary joint 210, is connected to a circular nozzle 218. The circular nozzle 218 has multiple spray holes 219 on its surface, and an annular grinding disc 213 is detachably mounted on its exterior. When the circular nozzle 218 is turned on and continuously sprays water, the water flows continuously inside the nozzle. Because the inner wall of the annular grinding disc 213 is attached to the outer wall of the nozzle, a heat conduction contact surface is formed between them. During the grinding process, the annular grinding disc 213 generates a large amount of heat due to intense friction with the workpiece. Heat rapidly accumulates inside the grinding disc, causing its temperature to rise sharply. At this time, the continuously flowing water inside the nozzle absorbs the heat from the inner wall of the annular grinding disc 213 through heat conduction. As the water continues to flow, the heat is continuously carried away, realizing the heat exchange process between the water and the annular grinding disc 213. Ultimately, through heat conduction and water flow heat exchange, the temperature of the annular grinding disc 213 is directly reduced, effectively avoiding problems such as performance degradation and damage to the grinding disc caused by overheating, and ensuring the stable progress of the grinding process.

[0026] Further, see Figure 2 A dual-shaft motor 214 is installed at the bottom of the water tank 206. The output shafts at both ends of the dual-shaft motor 214 are connected to a rotating rod 215 via a coupling. A second gear 212 is fixed at one end of the rotating rod 215, and a first gear 211 meshes with the top of the second gear 212.

[0027] It is worth noting that, see Figure 1 The top and front end of the water tank 206 are connected to one end of the water pipe 207, and the other end of the water pipe 207 is detachably connected to the pipe cover 208.

[0028] It is worth noting that, see Figure 3 The bottom of the telescopic cylinder 205 is provided with an installation groove, and a second drive motor 220 is installed inside the installation groove. The output shaft of the second drive motor 220 is fixed with a water tank 206. When it is necessary to switch between the coarse grinding disc and the fine grinding disc, the second drive motor 220 is started. The second drive motor 220 drives the water tank 206 to rotate, and the water tank 206 drives the grinding discs on both sides to rotate, thereby allowing the annular grinding discs 213 on both sides to be rotated and switched for use.

[0029] It is worth mentioning that, see Figure 1 A limiting rod passes through the top of the movable block 204, and a first fixing plate 2 and a second fixing plate 202 are fixed at both ends of the limiting rod.

[0030] It should be noted that the clamping components can be of various types, such as mechanical chucks, which consist of a chuck body, jaws, and a drive mechanism. The chuck body is installed on the top of the device base box 1. By rotating the handle or driving the lead screw with a motor, the evenly distributed jaws move synchronously towards or away from the center, realizing the clamping and releasing of alloy parts of different sizes. Hydraulic chucks use hydraulic systems to generate pressure to precisely control the clamping force. Pneumatic chucks use compressed air to drive cylinders and other actuators for fast and flexible clamping. Vacuum adsorption chucks use a vacuum environment to adsorb and fix thin sheet-like parts with flat surfaces. All of these can ensure the stability of the parts during grinding.

[0031] When using an alloy parts grinding device, the alloy parts to be processed are first placed on the top of the device's base box 1 and clamped by a clamping assembly to ensure that the parts are fixed in position and will not shift during subsequent processing, thus providing a foundation for grinding. After clamping, the first drive motor 201 is started. The first drive motor 201 drives the threaded rod 203 to rotate. Since the moving block 204 is threadedly engaged with the threaded rod 203, the rotation of the threaded rod 203 is converted into the linear movement of the moving block 204. During the movement, the moving block 204 will simultaneously drive the telescopic cylinder 205 and the water tank 206 to move together. The movement of the water tank 206 further drives the annular grinding discs 213 on both sides to move, gradually bringing them closer to the grinding position. When the annular grinding discs 213 move to the appropriate grinding position, the telescopic cylinder 205 is started.The telescopic cylinder 205 extends downward, pushing the annular grinding disc 213 downward until it contacts the surface of the alloy part, preparing for the grinding operation. During the downward movement of the annular grinding disc 213, the dual-axis motor 214 is simultaneously activated. The dual-axis motor 214 drives the rotating rod 215 to rotate, which transmits power to the second gear 212. The second gear 212 meshes with the first gear 211, thereby driving the first gear 211 to rotate. The first gear 211 is connected to the second connecting pipe 217, which is rotatably connected via the rotating ring of the rotary joint 210. Therefore, the rotation of the first gear 211 will drive the second connecting pipe 217 to rotate. When the pipe body 217 rotates, the second connecting pipe body 217 is connected to the circular nozzle 218 and the annular grinding disc 213, thereby driving the circular nozzle 218 and the annular grinding disc 213 to rotate together. At this time, the annular grinding disc 213 begins to grind the surface of the alloy parts, removing excess material to achieve the required machining accuracy and surface quality. During the grinding process, the pump body 209 is activated, pumping water from the water tank 206 and conveying it to the rotary joint 210 through the first connecting pipe body 216. The design of the rotary joint 210 allows the water flow to pass smoothly even when the second connecting pipe body 217 is rotating. After the water flows into the second connecting pipe body 217, it is then conveyed to... Inside the circular nozzle 218, multiple nozzle holes 219 are provided on its surface. Water is sprayed out from the nozzle holes 219, forming a pressurized water flow that is directly sprayed toward the surface of the workpiece being ground. The water flow can promptly wash away debris, dust, and other impurities generated during the grinding process, preventing impurities from accumulating in the grinding area and affecting the grinding effect and the surface quality of the parts. At the same time, the water flow also has a certain cooling effect, reducing the temperature of the grinding area and reducing problems such as part deformation and grinding disc wear caused by high temperature. When the circular nozzle 218 is turned on and continuously sprays water, the water flow forms a continuous flow inside the nozzle. Because the inner wall of the annular grinding disc 213 is in contact with the nozzle... On the outer wall, a heat conduction contact surface is formed between the two. During the grinding process, the annular grinding disc 213 generates a large amount of heat due to the intense friction with the workpiece. The heat quickly accumulates inside the grinding disc, causing its temperature to rise sharply. At this time, the continuously flowing water in the nozzle absorbs the heat from the inner wall of the annular grinding disc 213 through heat conduction. As the water continues to flow, the heat is continuously carried away, realizing the heat exchange process between the annular grinding disc 213 and the workpiece. Ultimately, through heat conduction and water flow heat exchange, the temperature of the annular grinding disc 213 is directly reduced, effectively avoiding problems such as performance degradation and damage of the grinding disc due to overheating, and ensuring the stable progress of the grinding process.
