Description

Technical Field

[0001] The invention belongs to the technical field of grinding equipment, and in particular relates to a vibration grinding device for hardware parts. Background Art

[0002] The three-dimensional vibration grinder is a highly efficient grinding equipment, usually used for surface polishing, chamfering, burr removal, sharpening, rust removal and other processing of hardware parts. Abrasives and grinding fluids are usually placed in the vibration disk during operation. The grinding fluid can reduce friction and heat, reduce damage to the workpiece surface, and accelerate the removal of burrs and protrusions on the workpiece surface, thereby improving grinding efficiency and workpiece surface quality. However, the liquid level of the grinding fluid needs to be maintained in an appropriate range. If it is too high, it will affect the grinding and polishing effects, and if it is too low, it will affect the cooling effect. Some existing grinders are inconvenient to maintain the liquid level, and it is difficult to lower or increase the liquid level. Some grinders have large base vibrations during operation, and thicker shock-absorbing pads need to be installed on the bottom. Larger vibrations will also lead to frequent replacement of shock-absorbing pads. Summary of the invention

[0017] 1. A plugging component is provided to conveniently plug the first outlet pipe of the vibration plate. A water pump is provided and a liquid outlet pipe is provided on the plugging component. When the liquid level is too high, the grinding liquid can be conveniently discharged. When the liquid level is too low, the grinding liquid can be conveniently replenished.

[0026] The present invention is further illustrated below in conjunction with specific examples. The examples are implemented based on the technical solutions of the present invention. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0027] like Figure 1 As shown, a vibration grinding device for hardware parts includes a base 1, an elastic component 2, a vibration disk 3, a vibration motor 4, a blocking component 5 and a water pump 6. The base 1 is cylindrical, and four feet 12 are provided at the lower end of the base 1. The lower ends of the four feet 12 are connected to shock-absorbing pads. The elastic component 2 is connected to the upper end of the base 1. The elastic component 2 includes a plurality of coil springs, and the plurality of coil springs are distributed in a circular array at the upper end of the base 1. The vibration disk 3 is bowl-shaped as a whole, and a bottom plate 33 is provided at the lower end of the vibration disk 3. The bottom plate 33 of the vibration disk 3 is connected to the upper ends of the plurality of coil springs. A central column protruding upward is provided in the middle of the vibration disk 3, and the central column is hollow. The central column of this embodiment adopts a conical shape, which can obtain more processing capacity. The vibration motor 4 is connected to the vibration disk 3, and most of the vibration motor 4 is located in the central column. The first eccentric block 41 and the second eccentric block 42 are connected to the vibration motor 4. The first eccentric block 41 is connected to the lower output shaft of the vibration motor 4. The first eccentric block 41 is a fixed eccentric block, and its angle cannot be adjusted. The second eccentric block 42 is connected to the upper output shaft of the vibration motor 4. The second eccentric block 42 is an adjustable eccentric block, and its angle can be adjusted, so that the angle between the second eccentric block 42 and the first eccentric block 41 can be adjusted, so as to change the magnitude of the exciting force of the vibration motor 4. A accommodating chamber 301 is provided in the vibration plate 3, and the accommodating chamber 301 is used to accommodate abrasives and processed hardware parts. The vibration motor 4 generates an exciting force when working. Since the vibration plate 3 is movably connected to the base 1 through a coil spring, the exciting force drives the abrasives in the accommodating chamber 301 of the vibration plate 3 to produce three directions of movement, namely, up and down vibration, flipping from the inside to the outside, and spiral clockwise rotation. The parts and the abrasives rub against each other to achieve the purposes of chamfering, deburring, rust removal, polishing, etc.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the side wall of the vibration plate 3 is provided with a first outlet pipe 31, the first outlet pipe 31 is connected to the accommodating chamber 301, the first outlet pipe 31 is tilted downward, the outer edge of the first outlet pipe 31 is connected with a guide plate 32, the guide plate 32 is an arc plate, when the first outlet pipe 31 has material discharged, the guide plate 32 is used to guide the material to slide down. The plugging assembly 5 is detachably connected to the guide plate 32, the plugging assembly 5 is used to plug the first outlet pipe 31, the plugging assembly 5 includes a plugging plate 51, a limit bolt 52, a stopper rod 53 and a liquid outlet pipe 54, the plugging plate 51 is a circular plate, the size of which corresponds to the flange at the outlet end of the first outlet pipe 31, the limit bolt 52 is used to tighten the plugging plate 51, the stopper rod 53 is a hollow circular tube, the middle position of the stopper rod 53 is provided with a threaded hole corresponding to the limit bolt 52, the limit bolt 52 is threadedly connected to the stopper rod 53, and the guide plate 32 is provided with a first groove 321 corresponding to the stopper rod 53. When in use, the blocking rod 53 is placed horizontally in the first groove 321. At this time, the first groove 321 limits the displacement of the blocking rod 53. The limiting bolt 52 is threadedly connected to the threaded hole of the blocking rod 53. The top end of the limiting bolt 52 passes through the blocking rod 53 and rests on the center position of the sealing plate 51. The limiting bolt 52 presses the sealing plate 51 onto the first outlet pipe 31, thereby blocking the first outlet pipe 31. The sealing plate 51 and the first outlet pipe 31 are also provided with an annular gasket 511 to improve the sealing effect. A liquid outlet pipe 54 is connected to the sealing plate 51, and the liquid outlet pipe 54 is in communication with the accommodating chamber 301. A first filter screen is provided at the inlet end of the liquid outlet pipe 54, and the filter aperture of the first filter screen is smaller than the diameter of the abrasive, thereby blocking the abrasive. The liquid outlet pipe 54 is used to discharge the liquid in the accommodating chamber 301. A first liquid discharge valve 541 is provided on the liquid outlet pipe 54. The first liquid discharge valve 541 can be a manual valve or a solenoid valve. When the first liquid discharge valve 541 is opened, the liquid in the accommodating chamber 301 is discharged from the liquid outlet pipe 54.

[0029] like Figure 1 and Figure 5As shown, a first ring plate 11 is provided on the base 1, the first ring plate 11 is perpendicular to the side wall of the base 1 and connected to the lower end of the base 1, the water pump 6 and the water tank 61 are arranged on the first ring plate 11, the water pump 6 and the water tank 61 are located below the vibration plate 3, the water tank 61 is annular, so that the weight of the water tank 61 can be evenly pressed on the first ring plate 11, the liquid outlet pipe 54 is connected to the water tank 61 through the hose 55, the liquid discharged from the liquid outlet pipe 54 enters the water tank 61, and the suction end of the water pump 6 is connected to the water tank 61 , the outlet end of the water pump 6 is connected with a circulation pipe 62, which is in communication with the receiving chamber 301 of the vibration disk 3. The water pump 6 can pump the liquid in the water tank 61 into the receiving chamber 301. When in use, the water tank 61 stores grinding liquid. The level of the grinding liquid in the receiving chamber 301 of the vibration disk 3 cannot be too high or too low. When the level is too low, the grinding liquid is added to the receiving chamber 301 by the water pump 6. When the level is too high, the first drain valve 541 is opened, and the grinding liquid in the receiving chamber 301 flows into the water tank 61. In order to filter the grinding liquid, a liquid inlet pipe is provided on the water tank 61, and a second filter screen cylinder 601 is provided in the liquid inlet pipe. The hose 55 is connected to the liquid inlet pipe. The grinding liquid in the hose 55 enters the water tank 61 after being filtered by the second filter screen cylinder 601. The second filter screen cylinder 601 can intercept large particles of impurities. A filter screen cylinder can also be provided at the suction end of the water pump 6 to prevent large particles of impurities from entering the water pump 6. The water tank 61 is provided with a second liquid outlet pipe 611 , and the second liquid outlet pipe 611 is provided with a second liquid discharge valve 612 . The second liquid discharge valve 612 can be a manual valve or a solenoid valve. The second liquid outlet pipe 611 is set at the lower part of the water tank 61 to discharge the liquid in the water tank 61 .

[0030] like Figure 1As shown, the water tank 1 is arranged on the first ring plate 11, and the grinding liquid stored in the water tank 1 can increase the overall weight of the base 1 and reduce the vibration of the base 1 when working. The annular design of the water tank 1 can make the weight distribution of the grinding liquid uniform, further ensuring the vibration reduction effect. At the same time, since the grinding liquid is a liquid, when the base 1 and the water tank 1 vibrate and shake as a whole, due to the inertia of the liquid, the grinding liquid in the water tank 1 will form resistance to the movement of the water tank 1 and the base 1 (for example, when the base 1 and the water tank 1 move to the left as a whole, the grinding liquid in the water tank 1 will not move immediately, thereby forming resistance to the movement of the water tank 1 to the left, thereby giving the water tank 1 a rightward force, and when the base 1 and the water tank 1 move to the right as a whole, the grinding liquid moves relatively to the left, and will give the water tank 1 a leftward force). In addition, the grinding liquid is distributed in an annular shape, and the resistance effect is better. This asynchronous movement can consume the vibration energy of the base 1, which is conducive to reducing the shaking of the base 1. A partition plate 613 is provided in the water tank 61. The partition plate 613 is an annular plate and is arranged in the middle position of the water tank 61. The annular surface where the partition plate 613 is located divides the storage space in the water tank 61 in half. A plurality of first through holes 6131 are provided on the partition plate 613. The plurality of first through holes 6131 are distributed on the partition plate 613. The lower end of the partition plate 613 is also provided with a plurality of first through holes 6131. ​​By providing the first through holes 6131, the grinding liquid on both sides of the partition plate 613 can circulate with each other. However, when the base 1 and the water tank 1 are shaken as a whole, the resistance of the grinding liquid can act on the partition plate 613, so as to consume the vibration energy. At the same time, the partition plate 613 can reduce the shaking amplitude of the grinding liquid in the water tank 1.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
