Description

Technical Field

[0001] The utility model relates to the technical field of woodworking band sawing machines, and particularly relates to a saw blade guiding device for a woodworking band sawing machine with high precision and long service life. Background Technique

[0002] The saw blade guiding device of a woodworking band sawing machine is a key component to ensure the stability and accuracy of the saw blade during the cutting process. The main function of the guiding device is to change the installation angle of the saw blade to make it perpendicular to the workbench. Through the cooperation of the guiding wheel and the guiding block, the saw blade can maintain a stable movement trajectory during operation, ensuring the accuracy and precision of cutting. The height of the guiding structure needs to be determined according to the sizes of the saw blade and the workpiece.

[0003] If the saw blade often gets stuck during operation, the height of the guiding device may be too low, which will reduce the service life in the long run and thus needs to be adjusted higher; if the saw blade shows deviation during the working process, the height of the guiding device may be too high, resulting in low processing accuracy and thus needs to be adjusted lower. However, the existing methods for adjusting the height of the guiding device are relatively cumbersome and time-consuming and laborious to operate.

[0004] In view of the above problems, the utility model provides a saw blade guiding device for a woodworking band sawing machine with high precision and long service life. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , in order to solve the problem that the existing method of adjusting the height of the guide device is relatively cumbersome and time-consuming and laborious to operate, the following preferred technical solutions are provided:

[0024] A saw blade guide device for a woodworking band saw with high precision and long service life, including a guide device 2 installed on the band saw 1. The guide device 2 includes a receiving block 21. One end of the receiving block 21 is installed with a guide block 22 and a guide wheel 23. One side of the guide wheel 23 is attached to the outer wall of the saw blade of the band saw 1. The end of the guide wheel 23 far from the saw blade of the band saw 1 is installed with a distance control body 24. The upper end of the receiving block 21 is fixedly installed with a lower connecting cylinder 25. The upper end of the lower connecting cylinder 25 is fixedly connected with an adjusting rod 26. The outer wall of the end of the adjusting rod 26 far from the lower connecting cylinder 25 is slidably connected with an upper connecting sleeve 27. The outer wall of the upper connecting sleeve 27 is provided with a fixing component 28. The fixing component 28 includes a control block 281 rotatably connected to the outer wall of the upper connecting sleeve 27. One end of the control block 281 is fixedly connected with a threaded rod 282. The outer wall of the threaded rod 282 is threadedly connected with a movable block 283. One end of the movable block 283 close to the adjusting rod 26 is installed with a pressing component 284.

[0025] One end of the upper connecting sleeve 27 is fixedly connected to the outer wall of the band saw. The threaded rod 282 penetrates through the inner wall of the upper connecting sleeve 27, and the movable block 283 is slidably connected to the inner wall of the upper connecting sleeve 27.

[0026] There are two sets of pressing components 284, and they are symmetrically distributed about the center of the threaded rod 282. The pressing component 284 includes a central rotating shaft 2841 with one end fixedly connected to the movable block 283. A first clamping plate 2842 and a second clamping plate 2843 are rotatably connected to the inner wall of the central rotating shaft 2841. An elastic element 2844 is fixedly connected between the first clamping plate 2842 and the second clamping plate 2843. The first clamping plate 2842 and the second clamping plate 2843 are symmetrically distributed about the center of the central rotating shaft 2841, and both the first clamping plate 2842 and the second clamping plate 2843 are arc-shaped structures. When the elastic element 2844 is relaxed, the first clamping plate 2842 and the second clamping plate 2843 form an angle of 30 degrees.

[0027] Specifically, the saw blade on the band saw 1 is guided through the cooperation of the guide block 22 and the guide wheel 23. When height adjustment is required, directly pull the adjustment rod 26. By using the adjustment rod 26 to move on the inner wall of the upper connecting sleeve 27, after the adjustment rod 26 drives the guide block 22 and the guide wheel 23 to move to a suitable position, rotate the control block 281. By using the control block 281 to drive the threaded rod 282 to rotate simultaneously, the movable block 283 moves on the inner wall of the upper connecting sleeve 27, driving the two sets of pressing components 284 to press the adjustment rod 26 to ensure fixation, and the adjustment can be completed. When adjustment is required again, similarly, after driving the pressing component 284 away from the adjustment rod 26, pull the adjustment rod 26 and repeat the above operation. The operation is convenient, solving the problem that the existing method of adjusting the height of the guiding device is relatively cumbersome and time-consuming and laborious, and ensuring the high-precision and long-life use of the band saw 1.

[0028] When driving the two sets of pressing components 284 to press the adjustment rod 26, the angle between the first clamping plate 2842 and the second clamping plate 2843 becomes larger, so that the first clamping plate 2842 and the second clamping plate 2843 will wrap around the adjustment rod 26. When the angle between the first clamping plate 2842 and the second clamping plate 2843 becomes larger, the elastic element 2844 will be tightened. Through the elasticity of the elastic element 2844, the first clamping plate 2842 and the second clamping plate 2843 will clamp the adjustment rod 26 from the side end, further ensuring the fixation effect.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
