[0033] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the drawings. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0034] As Figure 1 shown, an embodiment of the present utility model provides a sheet grinding assembly, including: a support bottom plate 1, a first grinding assembly 2 and a second grinding assembly 3 mounted on the support bottom plate 1; the first grinding assembly 2 is connected to a driving device 7, one end of the second grinding assembly 3 meshes with the first grinding assembly 2, and the first grinding assembly 2 drives the second grinding assembly 3 to rotate; a first chute 11 is provided on the support bottom plate 1, and the other end of the second grinding assembly 3 is movably arranged in the first chute 11 to be close to or away from the first grinding assembly 2.

[0035] In this embodiment, the proposed sheet metal grinding assembly uses at least two grinding assemblies that rotate synchronously, which can improve the grinding speed and shorten the grinding cycle. Among them, the first grinding assembly 2 and the second grinding assembly 3 are meshed and can be driven by a single driving device 7, which can not only achieve synchronous operation but also reduce the number of driving devices 7 used, so that a single person can use one driving device 7 to perform the grinding operation. The driving device 7 is a drill (such as a hand drill) or a motor.

[0036] It can be understood that grinding wheels are provided at one end of both the first grinding assembly 2 and the second grinding assembly 3. In this embodiment, the first grinding assembly 2 and the second grinding assembly 3 are implemented in the form of a gear set and a grinding wheel. Specifically, both the first grinding assembly 2 and the second grinding assembly 3 include a gear set fixed on the support base plate 1 and a grinding wheel installed at one end of the gear set. More specifically, the first grinding assembly 2 includes a first gear set fixed on the support base plate 1 and a first grinding wheel 23 sleeved at one end of the first gear set; the second grinding assembly 3 includes a second gear set fixed on the support base plate 1 and a second grinding wheel 33 sleeved at one end of the second gear set.

[0037] In this embodiment, the first gear set meshes with the second gear set and forms an acute angle, and a grinding gap is formed between the first grinding wheel 23 and the second grinding wheel 33. It can be understood that with the first grinding wheel 23 and the second grinding wheel 33 as the acting points, the first gear set and the second gear set respectively serve as the connecting arms of the first grinding wheel 23 and the second grinding wheel 33. Therefore, the first gear set meshes with the second gear set and forms an acute angle to clamp the sheet metal between the first grinding wheel 23 and the second grinding wheel 33 for grinding operation, place the sheet metal to be ground in the grinding gap for grinding, and the two sides of the sheet metal respectively contact the first grinding wheel 23 and the second grinding wheel 33, which can grind both sides of the sheet metal simultaneously, improve the grinding efficiency, and omit the step of manual turning; in addition, within the limited structural space of the grinding assembly, the design of the acute angle can optimize the layout of the gear set and save space.

[0038] Specifically, in this embodiment, the support base plate 1 is in the shape of a Figure 2 shown rectangular block, and the first grinding assembly 2 and the second grinding assembly 3 are arranged closely on the support base plate 1. Considering the diversity of sheet metal models and materials, a first sliding groove 11 is also provided on the support base plate 1. By adjusting the position of the other end of the second grinding assembly 3 in the first sliding groove 11, the effect of the second grinding assembly 3 approaching or moving away from the first grinding assembly 2 is achieved, which provides operability for quickly adjusting the grinding gap, enables the sheet metal grinding assembly to be applicable to grinding sheet metals of different thicknesses and materials, has wide applicability, and has a simple structural design, which is easy to operate and maintain.

[0039] As shown Figure 2 in the figure, the first chute 11 is a guiding chute provided on the supporting base plate 1. The first chute 11 has a curvature so that one end of the second gear set can move along an arc trajectory within the first chute 11. The first chute 11 has two ends, including a proximal end close to the first gear set and a distal end far from the first gear set. When it is necessary to make the second grinding wheel 33 close to the first grinding wheel 23, control one end of the second gear set to move along the first chute 11 towards the proximal end. The second gear set drives the second grinding wheel 33 to approach the first grinding wheel 23, thereby reducing the distance between the two grinding wheels. When it is necessary to make the second grinding wheel 33 far from the first grinding wheel 23, adjust one end of the second gear set to move along the first chute 11 towards the distal end. The second gear set drives the second grinding wheel 33 to move, and then away from the first grinding wheel 23, increasing the distance between the two grinding wheels. By adjusting the position of one end of the second gear set within the first chute 11, the second grinding wheel 33 is driven to move, so that the second grinding wheel 33 approaches or moves away from the first grinding wheel 23, achieving the purpose of adjusting the grinding distance.

[0040] In this embodiment, the gear set transmission is adopted, the structure is more compact, and the grinding assembly runs more stably. The gear transmission has good stability and reliability, reducing the problem of inconsistent grinding caused by problems such as belt slipping or chain stretching. At the same time, the weight and volume of the plate grinding assembly are controlled as much as possible to achieve portability and hand-held operation. A grinding distance is formed between the first grinding wheel 23 and the second grinding wheel 33. The plate is placed at the grinding distance position, and both the front and back sides of the plate can be ground simultaneously, improving the grinding efficiency and shortening the processing time. By adjusting the position of one end of the second gear set within the first chute 11, the second gear set is made to approach or move away from the first gear set, driving the second grinding wheel 33 to approach or move away from the first grinding wheel 23, and the grinding distance becomes smaller or larger, thereby realizing the adjustment of the grinding distance and providing the possibility for applying plates of different thicknesses and materials.

[0041] Further, please continue to refer to Figure 2 the figure. Each gear set includes a driving gear and a driven gear that mesh with each other, forming a reverse rotation gear set. The first gear set includes a first driving gear 21 and a first driven gear 22 that mesh with each other. The second gear set includes a second driving gear 31 and a second driven gear 32 that mesh with each other. In this embodiment, by adjusting the transmission ratio of the driving and driven gears, the rotation speed of the grinding wheel can be changed to adapt to plates of different hardnesses or thicknesses.

[0042] Further, please continue to refer to Figure 1 the figure. The driving device 7 is drivingly connected to the first driving gear 21, and the first driving gear 21 meshes with the second driving gear 31.

[0043] In this embodiment, the driving device 7 drives the first main gear 21. The first main gear 21 meshes with the second main gear 31. The first main gear 21 drives the second main gear 31. Each gear set also includes a meshing main gear and driven gear. Therefore, the first main gear 21 and the second main gear 31 also drive the first driven gear 22 and the second driven gear 32 respectively. Driving the entire grinding assembly with one driving device 7 provides the possibility for a single person to complete the double-sided grinding task of the board using only a single driving device. In addition, through the meshing of the first main gear 21 and the second main gear 31, it is ensured that the first grinding assembly 2 and the second grinding assembly 3 move synchronously, maintaining the consistency between the two sets of grinding wheels, thereby achieving a uniform grinding effect.

[0044] Further, the first grinding wheel 23 and the second grinding wheel 33 both include a central hole for sleeving the gear shaft. The first grinding wheel 23 and the second grinding wheel 33 are respectively sleeved on the gear shafts of the first driven gear 22 and the second driven gear 32 through the central holes.

[0045] In other specific examples, the key connection method can also be used to install the grinding wheel: by machining a keyway on the shaft of the driven gear and having a corresponding keyway on the hub of the grinding wheel, and through key connection, align and fix the hub of the grinding wheel with the shaft of the driven gear to ensure synchronous rotation of the two.

[0046] In other specific examples, the hub of the grinding wheel and the shaft of the driven gear can also be welded to achieve fixation.

[0047] In this embodiment, the grinding wheels sleeved on the first driven gear 22 and the second driven gear 32 simultaneously grind the two sides of the board, reducing the clamping times and processing time of the board, eliminating the need for manual turning of the board, and improving the double-sided processing efficiency. In addition, simultaneous double-sided grinding of the board helps to ensure the consistency of both sides of the board.

[0048] To further achieve adjustable grinding spacing, during the process of adjusting the grinding spacing, in order to precisely adjust the position of the second driven gear 32, a positioning structure and a second chute 12 are further provided on the support base plate 1. One end of the positioning structure is connected to the second driven gear 32, and the other end is accommodated in the second chute 12.

[0049] Specifically, the second chute 12 is another guiding groove provided on the support base plate 1. As Figure 2 shown, one side of the support base plate 1 extends outward to form the second chute 12. In Figure 2In it, the position of the second sliding groove 12 is on the same side as the position of the first sliding groove 11, and the second sliding groove 12 has an arc shape, so that the other end of the positioning structure can move along an arc trajectory, and the structure is compact, thus enabling the sheet grinding assembly to be as light as possible and operable by a single person carrying it by hand. One end of the positioning structure is connected to the second driven gear 32, and the other end of the positioning structure moves within the second sliding groove 12, driving the second driven gear 32 to move within the first sliding groove 11. In this embodiment, the positioning structure becomes a bridge connecting the second sliding groove 12 and the second driven gear 32. By changing the position of the positioning structure within the second sliding groove 12, the second driven gear 32 is driven to move within the first sliding groove 11. When the other end of the positioning structure moves within the second sliding groove 12, this movement is transmitted to the second driven gear 32 through the positioning structure, thereby affecting its position within the first sliding groove 11.

[0050] Specifically, the movement trajectory of the positioning structure from one end of the second sliding groove 12 to the other end is an arc. This movement is transmitted to the second driven gear 32 through the positioning structure. Correspondingly, the movement trajectory of the second driven gear 32 within the first sliding groove 11 is also an arc, and the centers of the two arcs coincide and coincide with the axis of the second main gear 31. Therefore, when the other end of the positioning structure moves within the second sliding groove 12, it will drive the second driven gear 32 to move within the first sliding groove 11.

[0051] The second sliding groove 12 not only provides an adjustment mechanism but also ensures the accuracy, repeatability, and convenience of the adjustment process. Through the cooperation of the second sliding groove 12 and the positioning structure, a single operator is allowed to precisely adjust the distance between the grinding wheel and the sheet, ensuring that the grinding requirements of sheets with different thicknesses are met, improving the versatility and flexibility of the grinding assembly, and the adjustment method is simple and the distance control is more precise.

[0052] Further, please refer to Figure 3 , to ensure the stability of the second driven gear 32 during the process of adjusting the grinding distance and prevent the second driven gear 32 from shifting during the grinding process, the positioning structure includes a fastener 5 and a connecting component 4. One end of the connecting component 4 is at least sleeved and fixed on the second driven gear 32, and the other end is movably arranged within the second sliding groove 12 and is connected to the fastener 5.

[0053] In this embodiment, one end of the connecting component 4 can be firmly sleeved on the second driven gear 32, and the other end can move freely within the second sliding groove 12. By fixing the other end of the connecting component 4 with the fastener 5, its position within the second sliding groove 12 is ensured to be stable, the connecting component 4 does not shift, and the second driven gear 32 does not shift correspondingly within the first sliding groove 11. Through the fastener 5 and the connecting component 4, the second driven gear 32 is effectively prevented from shifting during the grinding process.

[0054] The fixing function of the fastener 5 combined with the adjustability of the connection component 4 ensures the repeatability and stability of the adjustment mechanism. By moving the position of the connection component 4 within the second sliding groove 12, the position of the second driven gear 32 is adjusted. Once the desired position is reached, the fastener 5 is used to fix the connection component 4, preventing it from moving during operation and simultaneously locking the position of the second driven gear 32, completing the pitch adjustment and position fixing.

[0055] Furthermore, the connection component 4 includes a connection component main body and a positioning post 41. One end of the connection component main body is at least sleeved and fixed to the second driven gear 32. The other end of the connection component main body is provided with a positioning hole. The positioning post 41 is accommodated in the positioning hole. The positioning post 41 is movably arranged in the second sliding groove 12 and is connected to the fastener 5.

[0056] In this embodiment, the positioning post 41 is movably arranged in the second sliding groove 12. By adjusting the position of the positioning post 41, the position of the other end of the connection component main body in the second sliding groove 12 can be changed to achieve precise positioning. Secondly, one end of the connection component main body is sleeved and fixed to the second driven gear 32, and the other end is connected by the positioning post 41 and the fastener 5, forming a stable connection structure, ensuring the stable operation and stable fixation of the gear set during the grinding process: the connection between the positioning post 41 and the fastener 5 allows for the quick fixing or releasing of the position of the other end of the connection component main body.

[0057] Wherein, the positioning post 41 is provided with an external thread, and the fastener 5 has an internal thread or a corresponding shape to match the external thread of the positioning post 41. By screwing in or tightening the fastener 5, the connection and fixation with the positioning post 41 are achieved.

[0058] The fastener 5 includes a screw, a nut or a bolt.

[0059] The fastener 5 is further provided with a rotating handle, which facilitates the adjustment of the tightening degree through the rotating handle and is convenient for quickly fixing or releasing the position of the other end of the connection component main body.

[0060] Specifically, one end of the connection component main body includes a first fixing structure and a second fixing structure. The first fixing structure and the second fixing structure are respectively sleeved and fixed to the second driven gear 32 and the second main gear 31.

[0061] In this embodiment, the first fixing structure and the second fixing structure are in the shape of round holes, and their hole diameters respectively match the sizes of the shafts or flange plates of the second driven gear 32 and the second main gear 31. They can be directly sleeved on the shafts or flange plates of the second driven gear 32 and the second main gear 31 respectively, and then fixed by welding or bonding the contact parts.

[0062] The first fixed connection structure and the second fixed connection structure provide a simple fixing method for connecting the connecting component 4 and the second gear set. By directly sleeving and fixing, the additional support structure is reduced, thus simplifying the overall design and ensuring the stability of the second driven gear 32 and the second main gear 31 during operation. Moreover, the first fixed connection structure and the second fixed connection structure lengthen the force arm, making it more labor-saving for the user to adjust the grinding distance.

[0063] In this embodiment, the process of adjusting the grinding distance may specifically include the following steps:

[0064] Step 1: Prepare for adjustment

[0065] Ensure that the driving device 7 has been turned off and the plate grinding assembly is in a stopped state to ensure operation safety.

[0066] Step 2: Unlock the fastener 5

[0067] Rotate the rotating handle of the fastener 5 to unlock the connection between the fastener 5 and the positioning post 41 and release the position of the second driven gear 32.

[0068] Step 3: Adjust the position

[0069] Determine the required grinding distance according to the thickness of the plate to be ground and confirm the moving direction of the second driven gear 32.

[0070] Slowly push the connecting component 4 so that the other end of the connecting piece body moves in the second chute 12. The movement of the connecting piece body drives the movement of the second driven gear 32 in the first chute 11.

[0071] Step 4: Position the gear

[0072] When the second driven gear 32 is moved to the required position according to the required grinding distance, stop pushing the connecting component 4.

[0073] Confirm that the grinding distance between the second grinding wheel 33 and the first grinding wheel 23 meets the predetermined grinding requirements.

[0074] Step 5: Fix the position

[0075] Rotate the rotating handle of the fastener 5 in the reverse direction to tighten the fastener 5 to fix the positions of the positioning post 41 and the connecting piece body, thereby stabilizing the position of the second driven gear 32.

[0076] Confirm that the fastener 5 has been firmly fixed and the second driven gear 32 will not be displaced during grinding.

[0077] Step 6: Test and adjust

[0078] Restart the driving device 7, let the sheet grinding assembly run for a period of time, and observe the grinding effect.

[0079] If the grinding effect is not ideal, steps 2 to 5 above can be repeated to finely adjust the grinding spacing until the predetermined grinding effect is met.

[0080] It can be understood that the sheet grinding assembly mentioned in the above embodiments is a grinding core. In the actual application process, considering factors such as the length of the sheet and the convenience of user operation, in some preferred embodiments, the sheet grinding assembly further includes a sheet limiting structure. The sheet limiting structure provides a limiting surface for the sheet to be ground. The limiting surface is parallel to the support base plate 1. The first grinding wheel 23 and the second grinding wheel 33 form a grinding wheel set. The limiting surface is between the support base plate 1 and the grinding wheel set and is close to the side of the grinding wheel set facing the support base plate 1.

[0081] In this embodiment, the sheet limiting structure provides a limiting surface parallel to the support base plate 1. The movement range of the sheet between the grinding wheel set and the support base plate 1 is restricted through the limiting surface, ensuring the precise position of the sheet during the grinding process, preventing the sheet from shifting due to friction or vibration during the grinding process, and realizing positioning and guiding at the grinding depth level, neither over-grinding nor under-grinding. The first grinding wheel 23 and the second grinding wheel 33 form a grinding wheel set, which is responsible for grinding both sides of the sheet. The sheet is placed in the grinding spacing formed by the first grinding wheel 23 and the second grinding wheel 33. The position and angle of the sheet need to be precisely controlled to achieve a uniform and precise grinding effect. The sheet is placed in the grinding spacing, and the edge of the sheet abuts against the limiting surface, preventing the sheet from shifting due to vibration or thrust during the grinding process, which helps to maintain the flatness of the grinding surface of the sheet and avoid deformation of the sheet caused by uneven grinding.

[0082] Specifically, the sheet limiting structure includes a plurality of limiting rods and connecting rods, forming a frame structure to surround one side of the support base plate 1. The plurality of limiting rods are parallel to the support base plate 1 and form the limiting surface. One end of the connecting rod is connected to the limiting rod, and the other end is connected to the support base plate 1.

[0083] In this embodiment, the support base plate 1 serves as the basis of the entire grinding assembly, providing support and fixation for the grinding wheel set and the sheet limiting structure. The connecting rod plays a role in connecting the limiting rod and the support base plate 1, forming a stable structure to ensure the firm connection between the limiting rod and the support base plate 1. The design of the limiting rod and the connecting rod enables the sheet grinding assembly to effectively restrict the movement of the sheet, improving the grinding efficiency and quality, and having a simple structure, which is easy to install and adjust according to the sheet characteristics and specific massage requirements.

[0084] Further, it further includes a fixing frame 6. One end of the fixing frame 6 is fixed to the supporting bottom plate 1 by bolts or welding, and is arranged on the other side of the supporting bottom plate 1. The fixing frame 6 and the plate limiting structure are located on both sides of the supporting bottom plate 1 respectively. The other end of the fixing frame 6 limits the driving device 7 to ensure that the driving device 7 remains in the correct position during operation and prevent displacement due to vibration or impact. An opening for accommodating the driving device 7 is also provided at the other end of the fixing frame 6. Through this opening, the driving device 7 is connected to the first main gear 21. It should be noted that on the side of the fixing frame 6 close to the supporting bottom plate 1, there is a protective baffle connected and fixed to the supporting bottom plate 1 to protect the supporting bottom plate 1. The protective baffle is provided with an opening corresponding to the driving device 7 so that the driving device 7 can be connected to the first grinding assembly 2 on the supporting bottom plate 1.

[0085] In addition, in order to reduce vibration during the grinding process, a rubber pad is provided around the opening on the fixing frame 6 for accommodating the driving device 7. The rubber pad absorbs and isolates vibration, protects the driving device 7 and improves the grinding quality.

[0086] The fixing frame 6 further includes a plurality of support arms, and the support arms are used to connect the two ends of the fixing frame 6 to provide additional stability and support force.

[0087] In this embodiment, the fixing frame 6 provides a stable structure, which helps to improve the grinding accuracy, ensure the uniformity and consistency of the grinding effect, and at the same time provides an opening for accommodating the driving device 7, facilitating the disassembly and installation of the driving device 7 and the grinding assembly.

[0088] During the process of the grinding core unit grinding the plate, the plate is limited by the plate limiting structure to achieve a uniform and precise grinding effect; the fixing frame 6 provides a stable structure and support force for the grinding core unit.

[0089] It can be understood that in the above embodiment, the plate limiting structure and the fixing frame 6 provide the outer frame structure for the plate grinding assembly equivalent to the "grinding core unit", so that it is not only easy to smoothly advance and uniformly grind during the plate grinding process, achieve positioning and guiding, not over-grind nor under-grind, but also easy to connect and fix the driving device 7, and also easy to stabilize the overall structure of the plate grinding assembly, facilitating the overall processing operation of the user and improving the safety during the processing operation.

[0090] In the plate grinding assembly provided in this embodiment, the driving device 7 provides power to grind the plate, and among them, the driving device 7 is a motor or a drill.

[0091] In this embodiment, the driving device 7 is drivingly connected to the first main gear 21 of the first grinding assembly 2. The first main gear 21 is provided with a shaft hole matching the output shaft of the driving device 7. The output shaft of the driving device 7 is directly inserted into the shaft hole of the first main gear 21, and the dimensions of the output shaft of the driving device 7 and the shaft hole of the first main gear 21 are matched.

[0092] According to the required grinding spacing, adjust the position of the second driven gear 32 in the first chute 11, and lock the positioning post 41 and the fastener 5 in the second chute 12 to fix the position of the second driven gear 32.

[0093] The first main gear 21 is connected to the driving device 7, so that the first main gear 21 drives the first driven gear 22 and the second main gear 31. The second main gear 31 drives the second driven gear 32. The first driven gear 22 and the second driven gear 32 respectively drive the first grinding wheel 23 and the second grinding wheel 33 to simultaneously grind both sides of the plate, thereby ensuring the surface flatness and consistency of the plate after grinding, and improving the bonding effect of the plate and the product quality in the subsequent production process.
