[0006] To achieve the above objectives, the present invention provides the following technical solution:

Detailed Implementation

[0019] Please see Figures 1-3 In this embodiment of the invention, a saw blade grinding device includes a bracket 2, on which a first pad 1 is mounted and connected, and a grinding component 4 is mounted on the first pad 1. A second pad 5 is rotatably connected to the bracket 2 at a position opposite to the output end of the grinding component 4 via a rotating shaft. A fixed trajectory adjustment component 7 is fixedly connected to the second pad 5, and a tooth-picking component 71 opposite to the end of the rotating shaft is mounted and connected to the output end of the fixed trajectory adjustment component 7.

[0020] A saw blade adjustment component 6 for driving the second pad 5 to rotate relative to the bracket 2 is installed on the side of the second pad 5 away from the fixed trajectory adjustment component 7. The output end of the saw blade adjustment component 6 is connected to the rotating shaft for transmission.

[0021] In this embodiment, preferably, the device is used to process and grind the saw blade 9. The saw blade 9 is installed on one side of the second pad 5. When the grinding component 4 is started, the edge of the saw blade 9 can be ground. After the saw blade adjustment component 6 is started, the second pad 5 can be rotated relative to the bracket 2. This allows the edge of the saw blade 9 to move closer to the grinding component 4, making it easier to adjust the processing position and angle. After reaching the appropriate position, the fixed trajectory adjustment component 7 drives the tooth-shifting component 71 to move. The end edge of the tooth-shifting component 71 cooperates with the saw blade 9 during the movement and moves the saw blade 9 to form a certain angle of rotation. In this way, each tooth on the saw blade 9 can be ground step by step. The overall grinding angle is flexibly and stably controlled, and the grinding process is automatic and complete, allowing for comprehensive and complete processing of each tooth on the saw blade 9.

[0022] Please see Figure 1 In this embodiment of the invention, the first pad 1 is slidably connected to one side of the surface of the bracket 2, and a feeding component 3 for driving the first pad 1 to move relative to the second pad 5 is installed on the back of the bracket 2 away from the first pad 1.

[0023] In this embodiment, preferably, the feed assembly 3 can be composed of a servo motor and a lead screw and slider structure. The slider in the lead screw and slider is slidably fitted on the bracket 2, and the slider and the first pad 1 are fixedly connected. The lead screw is rotatably connected to one side of the bracket 2 through a bearing, and the end of the lead screw and the output end of the servo motor are connected by a belt drive.

[0024] In this embodiment, preferably, after the servo motor in the feed assembly 3 is started, it can drive the lead screw to rotate, thereby driving the first pad 1 to move in the vertical direction through the slider. During the lifting and lowering process, the first pad 1 can drive the grinding assembly 4 and the saw blade 9 to adjust the relative distance, so that the grinding position can be easily adjusted by moving and adjusting. It can also work with the second pad 5 to drive the rotation of the saw blade 9 to achieve precise positioning and higher processing accuracy.

[0025] Please see Figure 1 In this embodiment of the invention, the first pad 1 is provided with a relative moving component (not shown), the polishing component 4 is fixedly connected to the output end of the relative moving component, two sets of polishing components 4 are symmetrically arranged, and two sets of relative moving components are provided, and the output ends of the two sets of relative moving components are respectively connected to the two sets of polishing components 4.

[0026] In this embodiment, preferably, the relative movement component consists of a servo motor driven by a lead screw and slider assembly. The lead screw is rotatably connected to the first pad 1 and is perpendicular to the surface of the support 2. The slider is slidably engaged on the surface of the first pad 1 facing the second pad 5. The slider and the grinding assembly 4 are fixedly connected. After the servo motor is started, the rotating lead screw can drive the slider to move on the first pad 1. Through the independent movement of the two sets of lead screw and slider mechanisms, it is convenient to control the two sets of grinding assemblies 4 to form a clamping processing, thereby facilitating the synchronous grinding of both sides of the saw blade 9.

[0027] In this embodiment, preferably, the grinding assembly 4 includes a servo motor and a grinding wheel mounted and connected to the output end of the servo motor. The two servo motors drive the grinding wheel to rotate in opposite directions. This reduces interference with the saw blade 9 when grinding both sides of the saw blade 9 simultaneously, thus avoiding affecting the processing quality of the saw blade 9.

[0028] Please see Figure 1 In this embodiment of the invention, a chip collection plate 8 is fixedly connected to one side of the second pad 5. The chip collection plate 8 is located on the side of the rotating shaft away from the fixed trajectory adjustment component 7, and multiple sets of grooves are evenly distributed on the surface of the chip collection plate 8.

[0029] In this embodiment, preferably, the chip collection plate 8 is located on the side of the saw blade 9 away from the fixed trajectory adjustment component 7, and the rotation tangent direction of the two sets of grinding components 4 on opposite sides is towards the chip collection plate 8. In this way, when the second pad 5 rotates, the chip collection plate 8 can continuously maintain the position synchronization with the saw blade 9. When the grinding component 4 processes the saw blade 9, the grinding debris generated can be collected in a concentrated manner through the chip collection plate 8, which makes cleaning more convenient and the processing environment cleaner.

[0030] Please see Figure 1 and 3 In this embodiment of the invention, the trajectory adjustment component 7 includes a liner 72 fixedly installed on the side of the second pad 5. A mounting block 73 is slidably connected to the liner 72. The toothed component 71 is slidably installed on the surface of the mounting block 73 away from the liner 72. A lead screw 74 is rotatably connected to the liner 72. The lead screw 74 passes through the mounting block 73 through a threaded engagement. The extension direction of the lead screw 74 is the same as the sliding engagement direction of the mounting block 73 and the liner 72. A guide component is connected to the bottom of the mounting block 73 and the lower side of the liner 72.

[0031] In this embodiment, preferably, a servo motor is connected to the end of the lead screw 74. Starting the servo motor can drive the lead screw 74 to rotate, thereby controlling the mounting block 73 to slide on the liner 72, which in turn can drive the tooth-shifting assembly 71 to shift the saw blade 9. The adjustment is flexible and convenient. When the mounting block 73 slides relative to the liner 72, the guide assembly controls the tooth-shifting assembly 71 to move relative to the mounting block 73 in the vertical direction, which can easily form a flexible movement trajectory of the tooth-shifting assembly 71.

[0032] Please see Figure 1 and 3 In this embodiment of the invention, the guide component includes a connecting spring 75 fixedly mounted on the mounting block 73. A roller is connected to the bottom of the mounting block 73 via the connecting spring 75. A guide block 76 is fixedly connected to the bottom of the liner 72. The edge of the guide block 76 is arc-shaped, and the roller moves against the edge of the guide block 76.

[0033] In this embodiment, preferably, when the mounting block 73 slides away from the saw blade 9, the tooth-shifting assembly 71 is driven by the guide assembly to move downward in an arc. This allows the tooth-shifting assembly 71 to move away from the saw blade 9 after shifting the saw blade 9 by one tooth angle, so as not to affect the subsequent processing of the saw blade 9.

[0034] Working principle: First, the saw blade 9 to be processed is assembled onto one side of the second pad 5. The feed component 3 drives the first pad 1 to move vertically on the bracket 2, making it convenient to adjust and control the grinding component 4 to approach the saw blade 9. The saw blade adjustment component 6 is activated to control the second pad 5 to rotate relative to the bracket 2, thus adjusting the angle of the saw blade 9 to a suitable position. At this time, the relative movement component can control the output ends of the two sets of grinding components 4 to clamp the edge of the saw blade 9, thus facilitating grinding. After processing one set of saw blade 9 teeth, the fixed trajectory adjustment component 7 is activated to drive the tooth-shifting component 71 to shift the saw blade 9, thereby gradually completing the processing of all teeth. The overall processing angle and position are flexible and convenient, and the processing is comprehensive.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
