Description

Technical Field

[0001] This utility model relates to the field of saw blade processing, and in particular to a saw blade double-sided grinding mechanism. Background Technology

[0002] During the processing of saw blades used for cutting, both sides and the front and rear corners of the saw blade need to be ground. The quality of grinding determines the cutting quality of the saw blade. However, when grinding the sides of the alloy teeth of traditional saw blades, the difference in the inclination angle of the alloy teeth between different saw blades is often ignored, resulting in insufficient grinding. This leads to a decrease in both the service life of the saw blade and the cutting quality. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0029] Please see Figure 1-9 This utility model provides an embodiment of a saw blade double-sided grinding mechanism, including a housing 6, a tooth changing assembly 2, two grinding assemblies 1, and a cantilever tilting and material-collecting assembly 5. The housing 6 is a main housing with the tooth changing assembly 2, the two grinding assemblies 1, and the cantilever tilting and material-collecting assembly 5 mounted on its upper surface. The tooth changing assembly 2 includes a connecting platform 25 and a base 20. The connecting platform 25 is fixedly installed on the upper surface of the base 20. A rotating base 27 is fixedly installed on the connecting platform 25, and a rotating shaft 26 is rotatably installed in the rotating base 27. A connecting main plate 38 is fixedly installed on the rotating shaft 26, and a tooth-shifting slide 30 is slidably adjusted on the connecting main plate 38. One sliding adjustment method involves using a drive motor 31 mounted on the connecting main plate 38, with a lead screw fixedly connected to the output end of the drive motor 31. The lead screw is threadedly connected to the tooth-shifting slide 30, and the lead screw controls the sliding adjustment of the tooth-shifting slide 30, thereby adapting to saw blades of other diameters. A fixing plate 32 is fixedly connected to the tooth-shifting slide 30. A tooth-shifting cylinder 34 is mounted on the fixing plate 32. A tooth-shifting plate 35 is rotatably mounted on the fixing plate 32. The upper extension of the tooth-shifting plate 35 abuts against the telescopic end of the tooth-shifting cylinder 34, and a tension spring connects it to the rear end of the tooth-shifting cylinder 34. A tooth-shifting pin 36 is fixedly mounted on the lower end of the tooth-shifting plate 35. A suspension arm 37 is rotatably mounted on the connecting platform 25. When the saw blade needs to be sharpened, the saw blade is suspended on the suspension arm 37. Mounted on the suspension arm 37, the position of the tooth-shifting slide 30 is adjusted so that the tooth-shifting pin 36 is aligned with the alloy teeth of the saw blade. The tooth-shifting cylinder 34 is activated, thereby pushing the tooth-shifting plate 35, causing the tooth-shifting pin 36 to reciprocate and move the alloy teeth of the saw blade in indexing motion. Then, the two grinding components 1 are controlled to grind the two sides of each alloy tooth of the saw blade, while the cantilever flipping and picking component 5 is responsible for removing the ground saw blade and sending it to the next work station for grinding.

[0030] It is worth mentioning that, in order to make the grinding on both sides of the saw blade more stable, in this embodiment, an installation frame 21 is also fixedly installed on the upper surface of the base 20. A telescopic cylinder 22 is fixedly connected in the installation frame 21. A rubber pressure block 23 is fixedly connected to the telescopic end of the telescopic cylinder 22. A second rubber pressure block 33 is provided on the connecting platform 25. The second rubber pressure block 33 and the first rubber pressure block 23 are located on the same horizontal line. When grinding, the telescopic cylinder 22 is activated, so that the first rubber pressure block 23 squeezes the saw blade and fixes the saw blade between the second rubber pressure block 33 and the first rubber pressure block 23. At the same time, a coolant pipe 24 for spraying coolant is also installed on the upper surface of the installation frame 21.

[0031] It should be noted that, in order to facilitate angle adjustment control when grinding both sides of the saw blade alloy teeth, in this embodiment, a platform groove 39 is provided on the upper end surface of the rotating base 27, and a pointer 40 is fixedly installed in the platform groove 39. A scale is provided on the upper outer surface of the rotating shaft 26, and the tip of the pointer 40 is aligned with the scale. A rotating arm 28 is fixedly installed on the rotating shaft 26, and a center rod 29 is fixedly installed at the center of the rotating shaft 26. The center rod 29 can be used for position calibration, and can also be used for angle adjustment during grinding. The rotating arm 28 is moved, thereby driving the rotating shaft 26 to rotate. The angle can be adjusted according to the scale as needed. During rotation, the entire connecting main board 38 will move. At this time, the saw blade is fixed between the first rubber pressure block 23 and the second rubber pressure block 33. Therefore, during the rotation, the saw blade will swing up and down around the fixed point between the first rubber pressure block 23 and the second rubber pressure block 33 to adjust the angle between the two sides of the alloy teeth and the grinding wheel 15, so as to grind both sides of the alloy teeth in all directions and greatly improve the grinding accuracy.

[0032] It is also worth mentioning that, in this embodiment, a grinding base 10 is fixedly installed on the upper surface of the chassis 6, and two grinding components 1 are respectively installed on the left and right sides of the grinding base 10. The grinding component 1 includes a first slide plate 12, a second slide plate 13 is slidably installed on the upper surface of the first slide plate 12, a power source 14 is fixedly installed on the upper surface of the second slide plate 13, a grinding wheel 15 is fixedly installed at the output end of the power source 14, a guide rail 11 is fixedly installed on the upper surface of the grinding base 10, a slider 17 is fixedly installed at the bottom of the first slide plate 12, and the slider 17 is slidably installed on the corresponding guide rail 11. The sliding direction of the first slide plate 12 is perpendicular to the sliding direction of the second slide plate 13. Servo motors are respectively installed at the left and right ends of the grinding base 10, and an adjusting screw 16 is respectively installed at the output end of each servo motor. Each adjusting screw 16 is threadedly connected to the corresponding first slide plate 12 to precisely control the grinding wheel 15 to approach the saw blade for grinding.

[0033] In practice, the saw blade to be ground is first vertically suspended on the suspension arm 37. The drive motor 31 is then controlled to adjust the tooth-shifting slide 30 so that the tooth-shifting pin 36 aligns with the alloy teeth of the saw blade. Simultaneously, the two second sliding plates 13 are adjusted so that the grinding wheels 15 align with the two end faces of the alloy teeth of the saw blade. During grinding, the telescopic cylinder 22 is activated, causing the rubber pressure block 23 to press the saw blade, fixing it between the rubber pressure block 33 and the first rubber pressure block 23. The two grinding wheels 15 are driven to approach the saw blade and grind the two sides of the alloy teeth. After each alloy tooth is ground, the rubber pressure block 23 is released, and the tooth-shifting cylinder 34 is activated, pushing the tooth-shifting plate 35. This causes the tooth-shifting pin 36 to reciprocate, moving the alloy teeth of the saw blade in indexing motion, thus grinding the next alloy tooth again, until all the alloy teeth of the saw blade are ground.

[0034] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
