[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Figures 1-4 The diagram shown is a complete structural schematic of a tool grinding and polishing device according to this utility model. Please refer to [link / reference]. Figures 1-4 This embodiment of a tool processing and fine grinding equipment includes a base 100, a support frame 110 vertically fixed to one side of the upper end of the base 100, a horizontally positioned limiting plate 200 driven to rotate by a drive device on one side of the support frame 110, an air expansion shaft 210 coaxial with the limiting plate 200 on one side of the limiting plate 200, and a circular tool core hole sleeve being positioned by the air expansion shaft 210. A clamping and limiting component 300 for clamping and stabilizing the circular tool is also provided on one side of the upper part of the base 100. A rail beam 400 is horizontally fixed to one side of the upper end of the support frame 110, and a suspension 500 driven to move left and right along the length direction of the rail beam 400 is slidably mounted on it. An electric push rod 600 is vertically fixed to the outer end of the suspension 500. A polishing machine 700 and an angle adjustment component 800 for adjusting the longitudinal rotation of the polishing machine 700 are provided at the bottom output end of the electric push rod 600.

[0026] A limiting stop 200 is located on the opposite end of the air expansion shaft 210 and coaxially fixed to a shaft 220. A bearing sleeve 230 for mounting the shaft 220 is fixed on one side of the support frame 110, and a motor 240 is mounted on the other side of the support frame 110, with the output shaft of the motor 240 coaxially connected to one end of the shaft 220. It can be understood that the expanding air expansion shaft 210 can coaxially fix the center hole of the circular cutter, and the limiting stop 200 can abut and limit the lateral position of the circular cutter. To prevent the circular cutter from laterally deflecting during rotation and grinding, a straight groove 120 is provided on one side of the upper part of the base 100. The clamping and limiting assembly 300 includes a first slide 310 that slides inside the straight groove 120, a mounting base 320 fixed to the top of the first slide 310, a clamping cylinder 330 that is horizontally and rotatably mounted on one side of the upper part of the mounting base 320 and coaxial with the air shaft 210, an anti-slip pad 331 located at the outer end of the clamping cylinder 330, and an electric push rod 340 that is provided inside the straight groove 120 and used to drive the first slide 310 to move left and right. The inner diameter of the clamping cylinder 330 is larger than the outer diameter of the air shaft 210, and the inner length of the clamping cylinder 330 is larger than the length of the air shaft 210. Specifically, in this embodiment, during installation, the mandrel of the circular blade is fitted onto the outside of the air shaft 210, and one side of the circular blade abuts against the limiting stop plate 200. Then, the air shaft 210 is activated to tighten and fix the circular blade. After completion, the mounting base 320 will automatically approach the air shaft 210 under the action of the electric push rod 240 until the clamping cylinder 330 covers the outside of the air shaft 210 and its end abuts against the side of the circular blade. In this way, when the motor 240 drives the air shaft 210 to rotate, the circular blade and the clamping cylinder 330 will rotate synchronously. There will be no skew of the circular blade during grinding. Compared with the traditional manual operation, it is simpler and faster, and improves work efficiency.

[0027] The upper inner side of the rail beam 400 has a straight slide groove 410 along its length. A second slide block 420 slides inside the straight slide groove 410. One end of the suspension 500 is fixed to the upper part of the second slide block 420. Threaded screws 430 are rotatably installed at both ends of the inner side of the straight slide groove 410. The threaded screws 430 are threadedly connected to the second slide block 420. A first servo motor 440 is also provided at the outer end of the rail beam 400 to drive the threaded screws 430 to rotate forward and backward. It is understandable that before grinding, the polishing machine 700 and the cylindrical grinding block 710 need to gradually approach the edge of the circular knife blade, and the left and right positions of the polishing machine 700 are adjusted according to the grinding angle and the thickness of the circular knife. Therefore, the first servo motor 440 drives the threaded screw 430 to rotate, and with the cooperation of the second linear slide groove 410 and the second slide block 420, the suspension 500, the electric push rod 600 and the polishing machine 700 can gradually approach or move away from the edge of the circular knife blade. The angle adjustment assembly 800 includes an L-shaped mounting bracket 810 fixed to the bottom output shaft end of the electric push rod 600, a rotating shaft 820 rotatably mounted on one side of the L-shaped mounting bracket 800, a second servo motor 830 disposed on one side of the L-shaped mounting bracket 800 for driving the rotating shaft 820 to rotate, and an angular displacement sensor 840 disposed on one side of the polishing machine 700; wherein, the polishing machine 700 is fixedly mounted on one end of the rotating shaft 820, and the bottom output end of the polishing machine 700 has a cylindrical grinding block 710. It can be understood that the radial surface of the cylindrical grinding block 710 is the grinding surface, and the relative angle between this grinding surface and the cutting edge of the circular cutter is the required fine grinding angle. Specifically, in this embodiment, when the circular cutter is clamped and in a rotating state, the second servo motor 830, in cooperation with the angular displacement sensor 840, automatically adjusts the tilt angle of the polishing machine 700 and the cylindrical grinding block 710 according to the required fine grinding angle of the blade. Subsequently, the electric push rod 600, the rail beam 400, and the drive unit drive the polishing machine 700 to gradually approach the circular cutter according to the lateral position, blade thickness, and height position of the circular cutter, and perform radial fine grinding and polishing on the blade. The control of the entire adjustment mechanism is preset by the controller according to the specifications of the circular cutter and the usage requirements. The operation is simple and efficient, and the practicality and efficiency of use are further improved.

[0028] Preferably, a control panel 900 is further provided on one side of the support frame 110. It can be understood that the control panel 900 is the main control unit of this technology and equipment. The control panel 900 can be a PLC controller, computer, etc., and is not limited thereto. The operator can use the control panel 900 to set data and control the start and stop of various drive parts and detection parts of the fine grinding equipment, making the equipment more convenient to use.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
