Description

Technical Field

[0001] This invention relates to the field of polishing mechanism technology, specifically a side polishing mechanism. Background Technology

[0002] In numerous industrial sectors such as machinery manufacturing and parts processing, the requirements for surface treatment of various workpieces are becoming increasingly stringent. Among these, grinding the sides of workpieces is a crucial step in ensuring surface quality, dimensional accuracy, and meeting the requirements of subsequent assembly processes. Traditional grinding processes mostly rely on manual operation or single-axis semi-automatic equipment, which presents the following technical problems: manual grinding is inefficient; existing automated equipment has limited freedom of movement, making it difficult to adapt to the processing needs of multi-angle and irregular curved surfaces, requiring frequent tooling adjustments and long changeover times; material positioning relies on manual calibration, which can easily lead to uneven grinding allowance due to clamping misalignment.

[0003] While robotic arm solutions have been introduced in recent years, their high cost and other issues hinder their widespread adoption in small and medium-sized processing scenarios. Therefore, there is an urgent need for a rapid positioning side grinding mechanism that can improve grinding efficiency and meet the needs of multi-angle and irregular curved surface processing. Summary of the Invention

[0004] The present invention mainly provides a side grinding mechanism to solve the problems of low efficiency of manual grinding in the prior art; limited degree of freedom of existing automated equipment, which is difficult to adapt to the processing needs of multi-angle and irregular curved surfaces, requiring frequent tooling adjustments and long changeover time; and material positioning relying on manual calibration, which is prone to uneven grinding allowance due to clamping offset.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A side-grinding mechanism includes a linear displacement module, a horizontal rotation mechanism mounted on the linear displacement module, a material lifting mechanism mounted on the horizontal rotation mechanism for driving material up and down, a material positioning mechanism for positioning the material on the material lifting mechanism, and a material limiting mechanism mounted on the material lifting mechanism for limiting the material; it also includes a lateral lifting displacement mechanism positioned above the processing station of the linear displacement module, an angle adjustment mechanism mounted on the lateral lifting displacement mechanism, a grinding mechanism mounted on the angle adjustment mechanism for grinding the side of the material; and a material unloading mechanism positioned at the unloading station corresponding to the linear displacement module. The linear displacement module can utilize existing technology, as long as it achieves the technical principle of driving corresponding components to perform linear displacement. Furthermore, the loading station, processing station, and unloading station are arranged based on the linear displacement module according to the processing flow, thereby guiding the setup of other components. The angle adjustment mechanism can utilize existing technology, as long as it achieves the technical principle of driving the grinding mechanism to adjust the angle. This allows the grinding disc to be adjusted to be parallel to the side of the workpiece, or to form an angle between the grinding disc and the side of the workpiece. This, in conjunction with other components, enables four-dimensional motion coupling of horizontal rotation, lifting, lateral displacement, and angle adjustment, achieving adaptive grinding of complex curved surfaces and improving adaptability compared to traditional three-axis equipment. The material positioning mechanism can employ a complete set of vacuum suction cups, enabling excellent adsorption and positioning of the product and flexibly locking the material to be processed.

[0006] Furthermore, the horizontal rotation mechanism includes a rotating seat mounted on the linear displacement module, the rotating seat being linearly displaced by the linear displacement module; a rotating bracket is mounted on the rotating seat, the rotating bracket being horizontally rotated by the rotating seat. The rotating seat can be any type from the prior art, as long as it can drive the corresponding components to perform horizontal rotational movement.

[0007] Furthermore, the material lifting mechanism includes a material lifting cylinder mounted on the rotating support, with a platform at the upper end of the cylinder. The platform is lifted and displaced by the material lifting cylinder. The material positioning mechanism is mounted on the platform. The material lifting cylinder can utilize existing technology. The platform allows for better placement of the products to be processed.

[0008] Furthermore, the material limiting mechanism includes a front lifting cylinder located at the front of the rotating support and a right lifting cylinder located at the right side of the rotating support. The front lifting cylinder is equipped with a front positioning frame, the rotating support has a rear positioning cylinder and a rear positioning frame, the right lifting cylinder has a right positioning frame, the rotating support has a left positioning cylinder and a left positioning frame. The front lifting cylinder, right lifting cylinder, rear positioning cylinder, and left positioning cylinder can all be cylinders from the aforementioned technology, as long as their technical principles are implemented.

[0009] Furthermore, the lateral lifting and displacement mechanism includes a processing bracket, on which a lateral displacement module is mounted, a lifting and displacement module is mounted, and a grinding mounting frame is mounted on the lifting and displacement module. The angle adjustment mechanism is mounted on the grinding and mounting frame. The processing bracket is configured to correspond to the processing station of the linear displacement module. In use, the lateral displacement module drives the corresponding components to move laterally, and the lifting and displacement module drives the corresponding components to move vertically.

[0010] Furthermore, the polishing mechanism includes a polishing power component mounted on the angle adjustment mechanism. The output end of the polishing power component is equipped with a polishing table, and a polishing disc limiting component is mounted on the polishing table. A polishing disc is detachably connected to the polishing disc limiting component. The detachable connection of the polishing disc to the polishing disc limiting component allows for convenient replacement of the polishing disc, reducing replacement time. The polishing disc can utilize existing technologies, such as sandpaper polishing discs, resin polishing discs, diamond polishing discs, silicon carbide polishing discs, etc., selected according to the specific polishing process and product. The polishing disc limiting component can employ a complete set of vacuum suction cups, enabling effective adsorption, fixation, and limiting of the polishing disc.

[0011] Furthermore, the device includes a hopper rack, on which a grinding disc displacement module is mounted. The grinding disc displacement module has a grinding disc mounting bracket for holding the grinding discs, and the grinding disc mounting bracket has a grinding disc pushing cylinder for moving the grinding discs. The grinding disc displacement module can be any existing module capable of linear displacement, as long as it can move the grinding disc mounting bracket to a position suitable for loading the grinding disc limiting component.

[0012] Furthermore, it includes a film-tearing frame, on which a film-tearing displacement cylinder is provided, and on which a film material clamping assembly is provided.

[0013] Furthermore, the material feeding mechanism includes a feeding bracket, a feeding displacement module is provided on the feeding bracket, a feeding lifting component is provided on the feeding displacement module, and a material picking and placing component is provided on the feeding lifting component.

[0014] Beneficial effects: The structure of this application can drive the corresponding components to move through the horizontal rotation mechanism, linear displacement module, lateral lifting displacement mechanism and angle adjustment mechanism. Thus, through the motion coupling of horizontal rotation, longitudinal displacement, lifting, lateral displacement and angle adjustment, adaptive grinding of complex curved surfaces can be achieved. Compared with traditional three-axis equipment, it has stronger processing adaptability. At the same time, the use of each component to grind is more efficient and accurate than manual grinding. The material positioning mechanism and the material limiting mechanism form a three-level closed-loop limiting positioning of coarse positioning, fine correction and flexible locking, so as to accurately position the product, avoid manual calibration and make the grinding accuracy more accurate.

Detailed Implementation

[0017] The following will provide a more detailed description of the technical solution of the side grinding mechanism involved in this invention, with reference to the embodiments.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] like Figure 1 , Figure 2As shown, a side grinding mechanism 7 in this embodiment includes a linear displacement module 1, a horizontal rotation mechanism 2 disposed on the linear displacement module 1, a material lifting mechanism 3 disposed on the horizontal rotation mechanism 2 for driving the material up and down, a material positioning mechanism for positioning the material on the material lifting mechanism 3, and a material limiting mechanism 4 disposed on the material lifting mechanism 3 for limiting the material; it also includes a lateral lifting displacement mechanism 5 disposed above the processing position of the linear displacement module 1, an angle adjustment mechanism 6 disposed on the lateral lifting displacement mechanism 5, a grinding mechanism 7 disposed on the angle adjustment mechanism 6 for grinding the side of the material; and a material unloading mechanism 8 disposed at the unloading position of the linear displacement module 1. The linear displacement module 1 can adopt existing technology, as long as it can realize the technical principle of driving the corresponding components to perform linear displacement. Simultaneously, based on the linear displacement module 1, the loading position, processing position, and unloading position are arranged according to the processing flow, thereby guiding the setting of other components. The angle adjustment mechanism 6 can utilize existing technology, as long as it can achieve the technical principle of driving the grinding mechanism 7 to adjust the angle. This allows the grinding disc of the grinding mechanism 7 to be adjusted to be parallel to the side of the workpiece to be processed, or to form an angle between the grinding disc and the side of the workpiece. This, in conjunction with other components, enables four-dimensional motion coupling of horizontal rotation, lifting, lateral displacement, and angle adjustment, achieving adaptive grinding of complex curved surfaces and improving the processing adaptability compared to traditional three-axis equipment. Specifically, the linear displacement module 1, the lateral lifting displacement mechanism 5, and the material unloading mechanism 8 are all mounted on their respective worktables. Figure 2The document also demonstrates the positions of the linear slide on the linear displacement module 1 at the loading station, processing station, and unloading station. Specifically, the linear displacement module 1 includes a linear displacement component 101 and a parallel linear displacement support 102. A horizontal rotation mechanism 2 is respectively mounted on the linear slide of the linear displacement component 101 and on the linear mating slide of the linear displacement support 102. In use, when a product requiring side grinding is placed on the material lifting mechanism 3, the material lifting mechanism 3 lowers the product and corresponding components, placing the product within the range of the material limiting mechanism 4 for adjusting the product's position. The material limiting mechanism 4 then adjusts the position of the product on the material lifting mechanism 3 to achieve the preset processing position. After adjustment, the material positioning mechanism positions the product on the material lifting mechanism 3, and then the material lifting mechanism 3 raises the product back to the processing height. The linear displacement module 1 moves the corresponding components and product to the processing station, and the horizontal lifting mechanism 5 drives the angle adjustment mechanism 6 and the grinding mechanism 7 to perform horizontal grinding. The linear displacement module 1 can move the product vertically and vertically, and can also coordinate with the linear displacement mechanism for longitudinal displacement during processing. The angle adjustment mechanism 6 can adjust the grinding angle of the grinding mechanism 7, thus ensuring proper grinding of the product's sides. The horizontal rotation mechanism 2 can also adjust the product's orientation horizontally, allowing for grinding of different sides. After grinding, the linear displacement module 1 moves the corresponding components and product to the material unloading mechanism 8. After the material positioning mechanism releases the product, the material unloading mechanism 8 removes and unloads the product from the material lifting mechanism 3. Finally, the linear displacement module 1 resets the corresponding components, allowing the next product to be ground to be received. The structure of this application enables the horizontal rotation mechanism 2, the linear displacement module 1, the lateral lifting displacement mechanism 5, and the angle adjustment mechanism 6 to drive the corresponding components to move. Through the motion coupling of horizontal rotation, longitudinal displacement, lifting, lateral displacement, and angle adjustment, adaptive grinding of complex curved surfaces can be achieved. Compared with traditional three-axis equipment, it has stronger processing adaptability. At the same time, the use of individual components for grinding improves work efficiency and grinding accuracy compared with manual grinding. The material positioning mechanism and the material limiting mechanism 4 form a three-level closed-loop limiting positioning of coarse positioning, fine correction, and flexible locking, which can accurately position the product, avoid manual calibration, and make the grinding accuracy more accurate.

The rotating seat 201 is linearly displaced by the linear displacement module 1. A rotating bracket 202 is disposed on the rotating seat 201, and the rotating bracket 202 rotates horizontally by the rotating seat 201.

Specifically, the material lifting mechanism 3 also includes a material lifting guide rod 303 mounted on the platform 302, which is slidably connected to a material lifting slide cylinder 304 mounted on the rotating bracket 202. In use, the material lifting cylinder 301 drives the platform 302 to move up and down, thereby driving the product on the platform 302 to move up and down, and then the material positioning mechanism adsorbs and positions the product.

Specifically, it includes at least two front lifting cylinders 401, two right lifting cylinders 402, two rear positioning cylinders 404, and two left positioning cylinders 407. In use, when the material lifting mechanism 3 lowers the product to between the front positioning frame 403, rear positioning frame 405, right positioning frame 406, and left positioning frame 408, the rear positioning cylinder 404 moves the rear positioning frame 405, and the left positioning cylinder 407 moves the left positioning frame 408, thereby pushing the product to the front positioning frame 403 and the right positioning frame 406. This allows for limiting and adjusting the product's position on the platform 302, which is faster and more convenient than manual adjustment. Furthermore, the front positioning frame 403, rear positioning frame 405, and left positioning frame 406... The side positioning frame 405, right side positioning frame 406, and left side positioning frame 408 are detachably connected to the corresponding cylinders and can be replaced according to the product. After adjustment, the material lifting mechanism 3 drives the product to rise, the front lifting cylinder 401 and the right lifting cylinder 402 drive the corresponding front positioning frame 403 and the right positioning frame 406 to fall to a certain height, and the rear positioning cylinder 404 and the left positioning cylinder 407 drive the corresponding rear positioning frame 405 and the left positioning frame 408 to retract to the lower part of the platform 302, thereby avoiding affecting the subsequent processing of the grinding mechanism 7.
