Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to an integrated sanding belt machine. Background Art

[0002] With the continuous development of belt sander technology, the role of belt sander polishing in the metal processing industry has become irreplaceable. At the same time, with the popularization of automation technology, most of the current belt sanders use robots to complete the grinding or polishing process, that is, the robot's manipulator clamps the workpiece to the belt of the belt sander for operation. Belt sanding equipment has been continuously improved, the technology has become more mature, and the functions have become more complete. Metal processing tasks such as surface polishing, circular polishing, trimming polishing and grinding, radius polishing, chamfering and deburring can all be successfully completed. However, in the existing technology, the equipment required for the metal grinding process, including the belt sander, is relatively scattered, and has not formed an integrated modular equipment, which occupies a large storage space in the production workshop.

[0003] For enterprises that need industrial batch processing, the existing scattered belt sanding machine configuration obviously cannot meet their high requirements for the integration and flexibility of the equipment used. In addition, the scattered belt sanding machine operation configuration requires high costs and limited automation.

[0004] At the same time, during the grinding process of the workpiece, it is often necessary to use sanding belts of different coarseness and fineness for grinding. Therefore, it is necessary to add workstations to arrange multiple sanding belts of different coarseness and fineness for use together. For the equipment configuration of more scattered grinding processes, once the workstations are added, the operating methods and equipment placement of each stage need to be adjusted accordingly, such as the operating method and position of the robot. This increases the inconvenience in metal processing operations. Utility Model Content

[0040] Example

[0041] Please refer to Figure 1 and Figure 6As shown, the present embodiment provides an integrated belt sanding machine, including a base 1 and a frame 2 arranged on the base 1; four connecting components 8 are provided and distributed in a matrix, the connecting components 8 include a connecting rod 81 and a fixing member 82, both ends of the connecting rod 81 pass through the frame 2 and are fixed to the frame 2 by the fixing member 82; four belt grinding components 3 are provided, two by two are symmetrically arranged on both sides of the frame 2, one belt grinding component 3 is connected to the same side of two connecting components 8, and each belt grinding component 3 has a sanding belt 35 of different specifications to provide different grinding coarseness and fineness; a workpiece grabbing mechanism 4 is provided on the base 1 to clamp the workpiece to any belt grinding component 3 for grinding; a conveying mechanism 5 includes two conveying units 51, which are provided on the side of the workpiece grabbing mechanism 4 away from the frame 2 to convey the workpiece close to or away from the workpiece grabbing mechanism; an electric control box 6 is provided at the bottom of the conveying mechanism 5, and the electric control box 6 is electrically connected to the belt grinding component 3, the workpiece grabbing mechanism and the conveying mechanism 5.

[0042] Specifically, in the present invention, the frame 2, the workpiece grabbing mechanism 4 and the conveying mechanism 5 are integrated on the base 1, and the operation of each process is controlled by the electric control box 6. During the processing, the workpiece is conveyed to the workpiece grabbing mechanism 4 by one of the conveying units 51 of the conveying mechanism 5. The workpiece grabbing mechanism 4 clamps the workpiece and brings the workpiece to the sanding belt 35 of the corresponding sanding belt grinding assembly 3 for grinding, and can adjust the alignment angle with the sanding belt grinding assembly 3 by rotating according to the grinding angle requirements. After grinding, the workpiece grabbing mechanism 4 brings the workpiece to another conveying unit 51 of the conveying mechanism 5, which conveys it to the next processing procedure.

[0043] Among them, both sides of the frame 2 are provided with a sanding belt grinding assembly 3, and one side is provided with two upper and lower sanding belt grinding assemblies 3. The two sanding belt grinding assemblies 3 are distributed in a hierarchical manner, which effectively saves the occupied space of the entire equipment. The sanding belts 35 of each sanding belt grinding assembly 3 have different specifications and can provide different grinding coarseness and fineness. When the workpiece grasping mechanism 4 is in operation, according to the different coarseness and fineness of the grinding requirements, the workpiece can be moved or switched to different sanding belt grinding assemblies 3, and the sanding work can be completed by sanding belts 35 of different coarseness and fineness.

[0044] At the same time, in the entire grinding process, it can be centrally controlled at the electric control box 6, and the transmission mechanism 5 is connected to other processing programs, with a high degree of automation, which greatly improves the processing efficiency of the workpiece and facilitates batch processing of the workpiece.

[0045] like Figure 3 and Figure 5As shown, the belt grinding assembly 3 includes a conveyor belt 39, a rotary driving member 31, a driving wheel 32, a driven wheel 33, a deflection correction tension wheel 34 and a sanding belt 35; one end of the transmission belt 39 is sleeved with the output end of the rotary driving member 31, and the other end is sleeved with the wheel rod of the driving wheel 32, and the rotary driving member 31 drives the transmission belt 39 to rotate to drive the driving wheel 32 to rotate; the sanding belt 35 is wound around the driving wheel 32, the driven wheel 33 and the deflection correction tension wheel 34; the driving wheel 32 drives the sanding belt 35 to transmit.

[0046] Specifically, the rotary drive member 31 is arranged on the frame 2, and the rotary drive member 31 drives the driving wheel 32 to rotate. The driving wheel 32 provides the driving force for the sanding belt 35 to rotate, so as to drive the sanding belt 35 to flow, so as to complete the grinding of the workpiece close to it. The driving wheel 32 and the driven wheel 33 are both arranged on the side close to the workpiece grasping mechanism 4. The sanding belt 35 passes around the driving wheel 32 and then passes around the driven wheel 33. The driving wheel 32 and the driven wheel 33 are used in coordination to push the sanding belt 35 downward, thereby increasing the grinding contact area of ​​the sanding belt 35; the deviation correction tensioning wheel 34 can move and correct the sanding belt 35 to control the tension or relaxation of the sanding belt 35. In this embodiment, the rotary drive member 31 is a motor.

[0047] Furthermore, the abrasive belt grinding assembly 3 further includes a tensioning drive 36, which is disposed at the deflection correction tensioning wheel and connected to the deflection correction tensioning wheel. By adjusting the cylinder pressure, the deflection correction tensioning wheel is driven to move toward or away from the driving wheel 32, thereby adjusting the tightness of the abrasive belt 35, ensuring that the abrasive belt 35 can have appropriate tension during the transmission process, improving its stability, and ensuring the normal operation of the abrasive belt 35. In this embodiment, the tensioning drive 36 is a cylinder.

[0048] Furthermore, the belt grinding assembly 3 also includes a crossbeam 37 and a cantilever 38, which are arranged at an angle on the frame 2, one end of the crossbeam 37 is connected to the tensioning drive 36, and the other end is connected to the driving wheel 32 and one end of the cantilever 38, and the other end of the cantilever 38 is connected to the driven wheel 33, and the crossbeam 37 and the cantilever 38 are used to fix the driving wheel 32, the driven wheel 33 and the deviation correction tensioning wheel 34, so as to improve the stability and adjustability of the belt grinding assembly 3 during operation.

[0049] like Figure 1 As shown, the workpiece grasping mechanism 4 includes a clamping component 41 and a moving component 42. The moving component 42 drives the clamping component 41 to move, rotate or retract. After the clamping component 41 of the workpiece grasping mechanism 4 grasps the workpiece, it can perform multi-axis rotation through the moving component 42 to provide a variety of operating angles to adjust the grinding angle.

[0050] The utility model further comprises a cover shell 7 , which is arranged above the base 1 .

[0051] In a preferred embodiment, Figure 1 As shown, two covers 7 are provided, and are respectively provided on both sides of the frame 2 provided with the abrasive belt grinding assembly 3, and one end of the abrasive belt grinding assembly 3 extends out of the opening end of the cover 7 and is opposite to the workpiece grasping mechanism. In this way, placing the abrasive belt grinding assembly 3 in the cavity can improve its working safety and enable it to work in a relatively closed environment.

[0052] In another preferred embodiment, Figure 2 and Figure 4 As shown, the cover 7 is arranged outside the frame 2 and the workpiece grabbing mechanism, and is connected to the electric control box 6. That is, the entire workpiece grinding process is completed in the cover 7, reducing the pollution of external dust and impurities, ensuring that the entire grinding process is in a relatively clean environment, making the workpiece relatively clean after grinding, and at the same time ensuring the safety of the staff using the equipment.

[0053] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
