Description

Technical Field

[0001] This invention relates to the field of grinding machine technology, and more specifically to a vibratory grinding machine and its grinding method. Background Technology

[0002] Vibratory grinding machines are common mechanical devices used for grinding, polishing, or removing fine dust particles from material surfaces. They work by using vibration to bring the grinding media into contact with the workpiece surface and applying pressure to achieve the desired processing effect. A vibratory grinding machine typically consists of a vibrator, grinding media, and a worktable. The vibrator generates a vibration frequency, which is transmitted to the worktable, causing the grinding media to rub against the workpiece surface, thus achieving the grinding purpose. Vibratory grinding machines offer advantages such as high processing efficiency, uniform processing, and ease of operation. They are widely used in machining, mold making, hardware processing, and electronic component manufacturing to remove oxide layers, improve surface finish, and enhance assembly accuracy. The grinding accuracy of a vibratory grinding machine is influenced by several factors, including the abrasive, grinding time, amplitude, and frequency.

[0003] In the existing technology, during the grinding process of material surface, large abrasive particles generally have a faster grinding speed, while small abrasive particles have better grinding precision. Therefore, in order to improve the grinding speed and precision, large abrasive particles are often used to rough process the material surface first, and then small abrasive particles are used to fine process the material surface. In the process of replacing abrasive particles, the vibratory grinder needs to be stopped to replace the abrasive particles inside, which affects the processing efficiency of the material surface. Summary of the Invention

[0004] The purpose of this invention is to provide a vibratory grinding machine and its grinding method, solving the following technical problems:

[0005] The question of how to replace the abrasive in a vibratory grinding machine during the processing.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A vibratory grinding machine includes a base and a grinding box. The grinding box is connected to the base by a spring. A material trough is provided on the base. A shock-absorbing pad is fixedly connected to the bottom of the base.

[0008] A first lifting cylinder and a second lifting cylinder are fixedly connected to the bottom of the grinding box. Both the first lifting cylinder and the second lifting cylinder are connected to the grinding box. The bottom end of the second lifting cylinder is fixed and connected to a material holding bucket.

[0010] The second lifting cylinder is equipped with a second lifting component, which is used to lift the abrasive in the holding bucket into the grinding box;

[0011] A vibration assembly is provided on the grinding box and is used to drive the grinding box to vibrate.

[0012] In one embodiment, the first lifting assembly includes a first lifting rod, which is rotatably disposed inside a first lifting cylinder. A first spiral lifting blade is fixedly connected to the first lifting rod, and a first stirring blade is fixedly connected to the bottom end of the first lifting rod.

[0013] Furthermore, the second lifting assembly includes a second lifting rod, which is rotatably disposed inside the second lifting cylinder. A second spiral lifting blade is fixedly connected to the second lifting rod, and a second stirring blade is fixedly connected to the bottom end of the second lifting rod. The second stirring blade is arc-shaped and is used to guide the abrasive material toward the direction of the second lifting rod.

[0014] Furthermore, the outer arc surfaces of both the first and second stirring blades are inclined.

[0015] An inclined bottom plate is fixedly connected to the material trough to guide the abrasive in the direction of the first stirring blade.

[0016] Furthermore, it also includes a first filter plate and a second filter plate. The first filter plate is rotatably connected in the connection port between the first feed cylinder and the grinding box. The first filter plate has a plurality of first circular holes. The second filter plate is rotatably connected in the connection port between the second feed cylinder and the grinding box. The second filter plate has a plurality of third circular holes. The inner diameters of the first and second circular holes are equal, and the inner diameter of the third circular holes is larger than that of the first circular holes.

[0017] Furthermore, a fixing plate is fixedly connected between the first lifting cylinder and the second lifting cylinder, and a dual-axis motor is fixedly connected to the fixing plate. A third guide wheel is fixedly connected to one end of the dual-axis motor, and a second eccentric wheel is fixedly connected to the other end of the dual-axis motor.

[0018] A fourth guide wheel is fixedly connected to both the first and second lifting rods. The third guide wheel is rotatably connected to the fourth guide wheel via a timing belt. The diameter of the third guide wheel is larger than that of the fourth guide wheel.

[0019] The first and second spiral lifting blades have opposite thread directions, and the first and second stirring blades have opposite arc directions.

[0020] Furthermore, a stirring rod is fixedly connected to the outer edge of the timing belt;

[0021] Both the first and second lifting cylinders are provided with through grooves to avoid the timing belt and the stirring rod.

[0022] Furthermore, it also includes a first shielding plate and a second shielding plate. The bottom of the grinding box is fixedly connected to a first electric telescopic rod and a second electric telescopic rod. The first shielding plate is fixedly connected to the telescopic end of the first electric telescopic rod and is used to shield the first round hole. The second shielding plate is fixedly connected to the telescopic end of the second electric telescopic rod and is used to shield the third round hole.

[0023] A protective inclined plate is fixedly connected to the bottom of the grinding box, and the first and second electric telescopic rods are both located below the protective inclined plate.

[0024] In one embodiment, the vibration assembly includes a rotating shaft rotatably connected to a grinding box, a plurality of agitators fixedly connected to the rotating shaft, and a first eccentric wheel fixedly connected to both ends of the rotating shaft, with the two first eccentric wheels being staggered.

[0025] A vibration motor is fixedly connected to the bottom of the grinding box, a second guide wheel is fixedly connected to the output end of the vibration motor, a first guide wheel is fixedly connected to the rotating shaft, and the second guide wheel is rotatably connected to the first guide wheel through a transmission belt.

[0026] A grinding method using a vibratory grinder comprises the following steps;

[0027] Step 1: Start the dual-axis motor to rotate in the forward direction and control the extension end of the second electric telescopic rod to retract, so as to transport the large abrasive particles pre-placed in the material container to the grinding box through the second material lifting component;

[0028] Step 2: Start the vibration motor to drive the rotating shaft to vibrate the grinding box and perform vibration grinding on the materials and abrasives inside the grinding box;

[0029] Step 3: Control the dual-axis motor to rotate in reverse, and control the extension ends of both the first and second electric telescopic rods to retract. The first lifting assembly transports the small abrasive particles pre-placed in the feeding trough to the grinding chamber, while the second lifting assembly transports the large abrasive particles from the grinding chamber to the feeding bucket. During the transport process, some of the small abrasive particles transported to the feeding bucket will leak out through the second round hole on the feeding bucket into the feeding trough. Beneficial effects of the invention:

[0030] (1) The present invention lifts the abrasive in the holding bucket to the top of the second spiral lifting blade through the second spiral lifting blade, and pushes and guides the abrasive in the holding bucket to the bottom of the second spiral lifting blade through the second stirring blade, so as to ensure that the second spiral lifting blade continuously lifts the abrasive. The abrasive lifted to the top of the second spiral lifting blade will pass through the third round hole and enter the grinding box, thereby achieving the purpose of adding large particles of abrasive to the grinding box.

[0031] (2) In this invention, the rotating shaft driven by the vibration motor rotates on the grinding box. The first eccentric wheel generates eccentric force during the rotation of the rotating shaft. In conjunction with the spring, the grinding box vibrates in the lateral direction on the base. The two ends of the grinding box also vibrate in a staggered direction, thereby achieving the effect of vibrating and grinding the material and abrasive in the grinding box. In addition, the rotation of the dual-axis motor can synchronously drive the second eccentric wheel to rotate, thereby driving the grinding box to vibrate in the horizontal direction, which further increases the vibration direction of the grinding box, so as to ensure uniform grinding of the material and improve the grinding efficiency.

[0032] (3) In this invention, as the two abrasives are mixed in the grinding box, small abrasive particles will also pass through the third circular hole into the material container. The material container has multiple second circular holes. The small abrasive particles entering the material container will pass through the second circular holes and fall into the material trough. They will roll towards the first stirring blade on the inclined bottom plate and then be circulated and transported to the grinding box. In this way, the large abrasive particles in the grinding box can be gradually replaced with small abrasive particles through the cooperation of the first spiral lifting blade and the second spiral lifting blade. During this process, the grinding precision of the material surface is also gradually improved, thereby achieving the purpose of replacing the abrasive in the vibratory grinder during the processing, thereby improving the processing efficiency of the material surface.

A first guide wheel 33 is fixedly connected to the rotating shaft 3. The second guide wheel 41 is rotatably connected to the first guide wheel 33 through a transmission belt 42.

[0063] A grinding method using a vibratory grinder comprises the following steps;

[0064] Step 1: Start the dual-axis motor 9 to rotate forward and control the extension end of the second electric telescopic rod 6 to retract. The large abrasive particles pre-placed in the holding bucket 81 are transported to the grinding box 2 through the second lifting assembly. In the specific process of transporting the large abrasive particles, the dual-axis motor 9 rotates forward, driving the third guide wheel 92 to rotate. The third guide wheel 92 drives the fourth guide wheel 10 to rotate through the timing belt 93, thereby driving the second lifting rod 82 to rotate. During the rotation of the second lifting rod 82, the abrasive particles in the holding bucket 81 can be lifted to the top of the second spiral lifting blade 84 through the second spiral lifting blade 84. The abrasive particles in the holding bucket 81 are pushed and guided to the bottom of the second spiral lifting blade 84 through the second stirring blade 83 to ensure that the second spiral lifting blade 84 continuously lifts the abrasive particles. The abrasive particles lifted to the top of the second spiral lifting blade 84 will pass through the third round hole 851 and enter the grinding box 2, thereby achieving the purpose of adding large abrasive particles to the grinding box 2.

[0065] Step 2: Start the vibration motor 4 to drive the rotating shaft 3 to rotate, causing the grinding box 2 to vibrate and perform vibration grinding on the material and abrasive inside the grinding box 2. Specifically, when the abrasive delivered to the grinding box 2 reaches the grinding requirement, start the vibration motor 4. The vibration motor 4 drives the second guide wheel 41 to rotate. The second guide wheel 41 drives the first guide wheel 33 to rotate through the transmission belt 42, thereby driving the rotating shaft 3 to rotate on the grinding box 2. Since the two ends of the rotating shaft 3 are fixedly connected to the first eccentric wheel 32, and the two first eccentric wheels 32 are misaligned, the first eccentric wheel 32 will generate eccentric force during the rotation of the rotating shaft 3. Combined with the spring 12, the grinding box 2 vibrates in the lateral direction on the base 1, and the two ends of the grinding box 2 will also vibrate in the misaligned direction, thereby achieving the effect of vibration grinding on the material and abrasive inside the grinding box 2. In addition, the rotation of the dual-axis motor 9 can synchronously drive the second eccentric wheel 91 to rotate, thereby driving the grinding box 2 to vibrate in the horizontal direction, which further increases the vibration direction of the grinding box 2 to ensure uniform grinding of the material and improve grinding efficiency.

[0066] Step 3: Control the dual-axis motor 9 to rotate in reverse, and control the extension ends of both the first electric telescopic rod 5 and the second electric telescopic rod 6 to retract. The small abrasive particles pre-placed in the feeding trough are conveyed to the grinding box 2 via the first lifting assembly. The large abrasive particles in the grinding box 2 are conveyed to the feeding bucket 81 via the second lifting assembly. During the conveying process, some of the small abrasive particles conveyed to the feeding bucket 81 will leak out into the feeding trough through the second round hole 811 on the feeding bucket 81. Specifically, after the material has been initially ground by the large abrasive particles, control the dual-axis motor 9 to rotate in reverse, and control the extension ends of both the first and second electric telescopic rods. 6. The obstruction of the first circular hole 741 and the third circular hole 851 is removed respectively. During the reverse rotation of the dual-axis motor 9, the fourth guide wheel 10 can be driven to rotate in the reverse direction through the third guide wheel 92, thereby causing the first lifting rod 71 and the second lifting rod 82 to rotate in the reverse direction. The reverse rotation of the first lifting rod 71 can transport the small abrasive particles in the trough to the top of the first spiral lifting blade 73 through the first spiral lifting blade 73. The first stirring blade 72 pushes and guides the small abrasive particles in the trough towards the bottom of the first spiral lifting blade 73. The small abrasive particles transported to the top of the first spiral lifting blade 73 will pass through the first circular hole 741 and enter the grinding wheel. Inside the grinding chamber 2, the large abrasive particles mixed with the grinding chamber 2 are simultaneously released into the second lifting cylinder 8 through the third circular hole 851. Driven by the second spiral lifting blade 84, they enter the holding tank 81. The large abrasive particles falling to the bottom of the holding tank 81 collide with the inclined surface of the second stirring blade 83 during its rotation, causing them to move upwards within the holding tank 81. This process continues, with subsequent large abrasive particles fed in by the second spiral lifting blade 84 continuously falling into the holding tank 81. As the two types of abrasive mix in the grinding chamber 2, smaller abrasive particles also pass through the third circular hole 851 into the holding tank 8. Inside the material container 81, multiple second circular holes 811 are provided. Small abrasive particles entering the material container 81 will fall into the material trough through the second circular holes 811 and roll towards the first stirring blade 72 on the inclined bottom plate 13, and then be circulated and transported to the grinding box 2. In this way, through the cooperation of the first spiral lifting blade 73 and the second spiral lifting blade 84, the large abrasive particles in the grinding box 2 can be gradually replaced with small abrasive particles. During this process, the grinding precision of the material surface is also gradually improved, thereby achieving the purpose of replacing the abrasive in the vibratory grinder during the processing, thereby improving the processing efficiency of the material surface.

[0067] It should be noted that during the process of the first spiral lifting blade 73 conveying small abrasive particles into the grinding box 2 or the second spiral lifting blade 84 conveying large abrasive particles into the grinding box 2, when the abrasive particles are conveyed to the top of the first spiral lifting blade 73 or the top of the second spiral lifting blade 84, the abrasive particles may be squeezed against each other and unable to pass through the first round hole 741 or the third round hole 851 in time to enter the grinding box 2. At this time, the stirring rod 931 will stir and agitate the abrasive particles as the timing belt 93 rotates, thereby adjusting the position of the abrasive particles below the first filter plate 74 and the second filter plate 85, so that the abrasive particles can quickly pass through the first round hole 741 or the third round hole 851, thereby improving the feeding speed of the abrasive particles. In addition, the third round hole 851 is mainly used for screening materials and abrasive particles to prevent materials from falling into the second lifting cylinder 8 through the connection port of the second lifting cylinder 8 and 2.

[0068] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
