Description

Technical Field

[0001] This invention relates to the field of polishing, specifically to a multifunctional polishing device. Background Technology

[0002] Grinding equipment, as an important surface finishing technology, is widely used in many industries. However, traditional grinding equipment has some limitations in confined spaces, including low operating efficiency, large size, and poor quality stability (affected by the operator's skill level). Traditional grinding equipment usually has a fixed stroke and grinding area, and cannot be flexibly adjusted according to the size and shape of the grinding area. This brings a series of problems to the grinding process, such as some areas not being fully ground, resulting in uneven grinding quality. In addition, the non-adjustability of traditional grinding equipment also leads to low grinding efficiency. In practical applications, multiple adjustments are often required to achieve full grinding, increasing production time and costs. Therefore, in order to meet the market demand for more efficient, precise, and intelligent grinding equipment, it is necessary to introduce new technologies and improve existing equipment.

[0003] In summary, existing grinding equipment has a fixed stroke and cannot be adjusted according to actual needs. This means it cannot adapt to grinding areas of workpieces of different sizes and shapes, sometimes resulting in some areas not being fully ground, affecting the final grinding quality. Furthermore, existing grinding equipment typically has a fixed grinding area, which cannot be adjusted according to the size of the workpiece and specific requirements. This leads to wasted energy and materials when processing smaller workpieces, while larger workpieces may not be able to fully cover the grinding area. Summary of the Invention

[0004] This invention relates to a multifunctional grinding device and its adjustment method, which addresses the problems existing in the prior art. The device comprises two parts: a stroke adjustment module and an area adjustment module, designed to realize the reciprocating motion of the grinding head, and the reciprocating stroke and grinding area can be adjusted according to different workpiece sizes.

[0005] A multi-functional grinding device includes a drive motor, the output end of which is connected to a stroke adjustment component, the end of which is connected to an area adjustment module, and a buffer mechanism is also provided on the area adjustment module.

[0006] Furthermore, the stroke adjustment module includes a base, one end of which is connected to a drive motor, and the other end is fixedly connected to a base housing. A dovetail-grooved disc is rotatably mounted inside the base housing. A first dovetail groove is formed on the side of the dovetail-grooved disc away from the drive motor. A dial is slidably mounted in the first dovetail groove. An irregular groove is formed on the side of the dial near the first dovetail groove, and an actuating element is slidably mounted in the irregular groove. A first worm gear mechanism is provided in the cavity between the base and the dovetail-grooved disc. The first worm gear mechanism includes... A first worm gear and a first worm wheel are connected, with the first worm gear meshing with the first worm wheel. The dovetail groove disc is fixedly connected to the first worm wheel by a pin. Both the first worm wheel and the dovetail groove disc have through holes at their centers. The output shaft of the drive motor passes through the through holes and is fixedly connected to the actuating component. The actuating component has three levers arranged circumferentially, and each lever has a bearing installed at its end. A drive rod is fixedly installed on the side of the dial away from the first dovetail groove, and a dovetail-shaped guide rail is provided on the side of the base housing away from the base.

[0007] Furthermore, the area adjustment module includes a cover, which slides with a dovetail guide rail on the base housing via a second dovetail groove. A boss is located in the center of the cover, and a rectangular groove is formed on the side of the boss facing the base housing. The direction of the rectangular groove is perpendicular to the direction of the second dovetail groove. The drive rod passes through the base housing and slides with the rectangular groove. A circular groove is formed on the side of the boss away from the base housing. The grinding housing is fixedly connected to the cover. A second worm gear mechanism and a planetary gear system are arranged in the cavity between the grinding housing and the cover. The second worm gear mechanism includes a second worm wheel and a second worm, which mesh with each other. The planetary gear system includes three planet gears, a sun gear, and a ring gear. The sun gear is rotatably mounted at the center of the planetary gear system, and the ring gear is fixedly mounted inside the grinding housing. Three rows of gears are arranged in an array between the sun gear and the ring gear. The planetary gear has a stepped shaft with one end rotatably mounted in a circular groove and the other end passing through a second worm gear and fixedly connected to a sun gear. Three through slots are provided on the end face of the grinding housing, arranged in a 120° array along the center line of the grinding housing. Three through holes are provided on the circumference of the grinding housing, their positions corresponding to the positions of the three through slots. The stepped shaft is keyed to the second worm gear. A gear carrier is fitted onto the stepped shaft and located between the second worm gear and the sun gear. The gear carrier has three first connecting pins. Each first connecting pin passes through a corresponding planetary gear and is hinged to one end of a first connecting rod. The other end of the first connecting rod is hinged to one end of a second connecting pin. The middle of the second connecting pin is hinged to one end of the second connecting rod. The other end of the second connecting pin passes through the second connecting rod and slides through a through slot in the grinding housing. The other end of the second connecting rod is fixedly connected to the grinding block.

[0008] Furthermore, the buffer mechanism includes a support block, which is fixed on the grinding block. The buffer block is positioned on the support block by bolts, and a spring is sleeved on the bolts, located between the support block and the buffer block.

[0009] An adjustment method based on a multi-functional grinding device includes the following steps:

[0010] S1. Adjust the sanding area

[0011] When the second worm is rotated in the forward direction, the second worm wheel rotates clockwise under the drive of the second worm, thereby causing the sun gear to rotate clockwise and the planet gears to rotate counterclockwise. Under the action of the first connecting pin, the first connecting rod, the second connecting pin, and the second connecting rod, the grinding block is driven to open outward, thereby increasing the grinding area. When grinding a smaller space is required, the second worm is rotated in the reverse direction, causing the grinding block to retract inward, thereby reducing the grinding area.

[0012] S2. Adjust the reciprocating motion stroke.

[0013] Manually rotate the first worm gear to drive the first worm wheel to rotate, which in turn drives the dovetail groove disc to rotate, changing the direction of the dial's reciprocating linear motion;

[0014] The stroke length can be calculated using the following formula:

[0015] S=L·sinθ

[0016] Where L is the reciprocating stroke of the dial, and θ is the angle between the dial and the rectangular groove of the cover. As the angle θ increases, the corresponding reciprocating stroke also increases.

[0017] S3. Start the drive motor, which in turn drives the dial to reciprocate linearly along the first dovetail groove via the toggle. The drive rod on the dial drives the cover to reciprocate linearly along the second dovetail groove, thereby driving the entire expansion module to reciprocate linearly to achieve reciprocating grinding.

[0018] The multifunctional polishing device of the present invention has the following advantages:

[0019] 1. Simple structure and easy installation: The device of the present invention adopts a modular structural design, which is not only easy to install and can be quickly reconfigured, but also convenient to use.

[0020] 2. Reciprocating motion and area adjustment: By combining the stroke adjustment module and the area adjustment module, the reciprocating stroke and the grinding area can be adjusted separately according to the grinding needs, which greatly improves the applicable range of working conditions.

[0021] 3. Compact structure and high reliability: Most parts of the present invention are relatively symmetrical, and the stroke adjustment module and the area adjustment module are connected in series in a stacked manner, which greatly improves the compactness of the entire device. It can be used as a manual grinding tool and can also be quickly integrated into robots, machine tools and other equipment, with a wide range of applications. The use of worm gear to adjust the grinding stroke and grinding area has good self-locking properties, which makes the adjusted stroke and area stable and not easily affected by external forces, thus improving the stability and reliability of the device.

[0022] Based on the above advantages, the multifunctional grinding device of the present invention is suitable for grinding workpiece parts in various confined spaces, which can not only improve work efficiency, but also ensure the consistency and accuracy of grinding quality.

[0023] In summary, this invention provides a multifunctional surface polishing device that makes polishing work more flexible, efficient, and stable by adjusting the reciprocating stroke and polishing area, as well as by using a good self-locking worm gear adjustment method.

Driven by the drive motor D1, the actuating member 1.3 can rotate, thereby driving the dial 1.8 to reciprocate linearly along the first dovetail groove C1.

[0045] A drive rod Q1 is fixedly installed on the side of the dial 1.8 away from the first dovetail groove C1. A dovetail-shaped guide rail 1.21 is provided on the side of the base housing 1.2 away from the base 1.1. The cover 2.1 is slidably engaged with the dovetail-shaped guide rail 1.21 on the base housing 1.2 through the second dovetail groove C2. A boss is provided in the middle of the cover 2.1. A rectangular groove C3 is opened on the side of the boss facing the base housing 1.2. The direction of the rectangular groove C3 is perpendicular to the direction of the second dovetail groove C2. The drive rod Q1 passes through the base housing 1.2 and is slidably engaged with the rectangular groove C3. As the dial 1.8 moves linearly back and forth along the first dovetail groove C1, the drive rod Q1 on the dial 1.8 can drive the cover 2.1 to move linearly back and forth along the second dovetail groove C2.

[0046] A circular groove C4 is formed on the side of the boss away from the base housing 1.2. The grinding housing 2.2 is fixedly connected to the cover 2.1. A second worm gear mechanism and a planetary gear system 2.7 are arranged in the cavity between the grinding housing 2.2 and the cover 2.1.

Three planetary gears 2.71 are arranged in an array between wheel 2.72 and gear ring 2.73; one end of the stepped shaft 2.5 is rotatably mounted in a circular groove C4, and the other end passes through the second worm gear 2.3 and is fixedly connected to the sun gear 2.72. Three through slots C6 are opened on the end face of the grinding housing 2.2, and the three through slots C6 are arranged in a 120° array along the center line of the grinding housing 2.2. Three through holes 2.21 are opened on the circumferential surface of the grinding housing 2.2, and the positions of the three through holes 2.21 correspond to the positions of the three through slots C6. The stepped shaft 2.5 is keyed to the second worm gear 2.4, and the gear carrier 2.6 is sleeved on the stepped shaft 2.5 and positioned... Between the second worm gear 2.3 and the sun gear 2.72, the gear carrier 2.6 is provided with three first connecting pins 2.61. Each first connecting pin 2.61 passes through the corresponding planetary gear 2.71 and is hinged to one end of the first connecting rod 2.9. The other end of the first connecting rod 2.9 is hinged to one end of the second connecting pin 2.10. The middle part of the second connecting pin 2.10 is hinged to one end of the second connecting rod 2.81. The other end of the second connecting pin 2.10 passes through the second connecting rod 2.81 and slides into the through groove C6 of the grinding housing 2.2. The other end of the second connecting rod 2.81 is fixedly connected to the grinding block 2.8. The second worm gear 2.61 rotates forward... 4. The second worm gear 2.3 rotates clockwise under the drive of the second worm 2.4, thereby driving the sun gear 2.72 to rotate clockwise and the planet gear 2.71 to rotate counterclockwise. Under the action of the first connecting pin 2.61, the first connecting rod 2.9, the second connecting pin 2.10 and the second connecting rod 2.81, the grinding block 2.8 is driven to open outward, thereby increasing the grinding area. When grinding a smaller space is required, the second worm 2.4 is rotated in the opposite direction, driving the grinding block 2.8 to retract inward, thereby reducing the grinding area.

The bolts also act as guide posts, allowing the buffer blocks to move up and down along the bolts.

[0048] An adjustment method based on a multi-functional grinding device includes the following steps:

[0049] S1. Adjust the sanding area

[0050] When the second worm gear 2.4 is rotated in the forward direction, the second worm wheel 2.3 rotates clockwise under the drive of the second worm gear 2.4, thereby driving the sun gear 2.72 to rotate clockwise and the planet gear 2.71 to rotate counterclockwise. Under the action of the first connecting pin 2.61, the first connecting rod 2.9, the second connecting pin 2.10 and the second connecting rod 2.81, the grinding block 2.8 is driven to open outward, thereby increasing the grinding area. When grinding a smaller space is required, the second worm gear 2.4 is rotated in the reverse direction, causing the grinding block 2.8 to retract inward, thereby reducing the grinding area.

[0051] S2. Adjust the reciprocating motion stroke.

[0052] Manually rotate the first worm gear 1.4 to drive the first worm wheel 1.5 to rotate, which in turn drives the dovetail groove disc 1.6 to rotate, changing the direction of the reciprocating linear motion of the dial 1.8;

[0053] The stroke length can be calculated using the following formula:

[0054] S=L·sinθ

[0055] Where L is the reciprocating stroke of dial 1.8, and θ is the angle between dial 1.8 and the rectangular groove C3 of the cover 2.1. (Reference) Figure 4 and Figure 5 As the included angle θ increases, the corresponding reciprocating motion stroke also changes from small to large.

[0056] S3. Start the drive motor D1, which in turn drives the dial 1.8 to reciprocate linearly along the first dovetail groove C1 via the toggle 1.3. The drive rod Q1 on the dial 1.8 drives the cover 2.1 to reciprocate linearly along the second dovetail groove C2, thereby driving the entire expansion module to reciprocate linearly to achieve reciprocating grinding.
