[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please refer to Figures 1-6.

The components work together to achieve efficient and precise grinding and polishing of the tools.

[0021] Base 1: As the basic support component of the device, it is made of high-strength alloy material to ensure the stability and load-bearing capacity of the overall structure and provide a stable installation platform for each upper component.

[0022] Placement seat 2: Fixedly installed on the top of the base 1, used to support the clamping component 3. Its surface is precision machined to ensure the horizontality and positioning accuracy of the clamping component 3 after installation.

[0023] Clamping assembly 3 includes a clamping frame 31, a limiting rod 32, a bidirectional screw 33, a first motor 34, and clamping plates 35. The clamping frame 31 is fixed to the top of the placement base 2, and the limiting rod 32 and the bidirectional screw 33 are arranged parallel inside. The first motor 34 is installed outside the clamping frame 31, and its output shaft passes through the clamping frame 31 and is connected to the bidirectional screw 33 for transmission. The two clamping plates 35 are slidably sleeved on the limiting rod 32, and are respectively threaded onto the bidirectional screw 33 through two sections of threads in opposite directions on the bidirectional screw 33. Anti-slip rubber pads are attached to the opposite sides of the clamping plates 35 to enhance the clamping friction.

[0024] Lifting assembly 4: It consists of a support frame 41 and a lifting cylinder 42. The support frame 41 is fixed to the top of the base 1 by welding, and the structure is sturdy. The lifting cylinder 42 is installed inside the top of the support frame 41, and the output shaft passes through the support frame 41 and is rigidly connected to the lifting frame 5, providing a stable lifting driving force for the lifting frame 5.

[0025] Lifting frame 5: Made of lightweight high-strength profiles, with a push cylinder 6 installed on one side. Two symmetrically arranged guide rods 10 slide through the inside. One end of the guide rod 10 is connected to the transverse component 7 to ensure the stability of the transverse component 7 when it moves.

[0026] Push cylinder 6: High-precision pneumatic actuator is selected. The output shaft passes through the lifting frame 5 and is fixedly connected to the transverse component 7. It can push the transverse component 7 to make linear reciprocating motion along the guide rod 10, so as to realize the rapid adjustment of the front and rear positions of the grinding wheel 92.

[0027] The transverse movement assembly 7 includes a strip seat 71, a sliding seat 72, a mounting screw 73, and a second motor 74. The strip seat 71 has a precision groove inside, and the sliding seat 72 is fitted into the groove. The mounting screw 73 is rotatably mounted in the groove and threadedly connected to the sliding seat 72. The second motor 74 is fixed to the outside of the strip seat 71, and its output shaft is connected to the mounting screw 73, driving the sliding seat 72 to move laterally along the groove.

[0028] Angle adjustment assembly 8: Composed of a rotating frame 81, a rotating shaft 82, a sleeve block 83, a worm gear 84, an extension frame 85, a worm 86, and a motor 87. The rotating frame 81 is fixedly connected to the sliding seat 72 of the transverse component 7. The rotating shaft 82 is rotatably mounted inside the rotating frame 81, with one end passing through the rotating frame 81 and fixedly sleeved with the worm gear 84. The extension frame 85 is located outside the rotating frame 81, with the worm 86 rotatably mounted inside, and the worm 86 meshing with the worm gear 84. The motor 87 is mounted on the top of the extension frame 85, and its output shaft is drively connected to the worm 86. The sleeve block 83 is fixedly sleeved on the outside of the rotating shaft 82 and is used to connect the grinding component 9.

[0029] Grinding assembly 9 includes a grinding frame 91, a grinding wheel 92, and a grinding motor 93. The grinding frame 91 is rigidly connected to the sleeve block 83 of the angle adjustment assembly 8. The grinding wheel 92 is rotatably mounted inside the grinding frame 91 via a bearing. The grinding motor 93 is fixed to the top of the grinding frame 91, and its output shaft passes through the grinding frame 91 and is connected to the grinding wheel 92 for transmission, driving the grinding wheel 92 to rotate at high speed.

[0030] Guide rod 10: Two rods are provided, made of high hardness and wear-resistant material. They are symmetrically distributed about the pushing cylinder 6 and slide through the lifting frame 5 to connect with the transverse component 7. They play a guiding and stabilizing role and prevent the transverse component 7 from deviating when it moves.

[0031] When using, first place the tool to be sharpened between the two clamping plates 35, start the first motor 34, the first motor 34 drives the bidirectional screw 33 to rotate. Since the two clamping plates 35 are respectively connected to the two reverse threads of the bidirectional screw 33, and are limited by the guide of the limiting rod 32, the two clamping plates 35 will be relatively close to each other, and the tool is clamped by the anti-slip rubber pad to ensure stable clamping.

[0032] According to the tool grinding requirements, the lifting frame 5 is raised and lowered by the lifting cylinder 42 to adjust the height of the grinding wheel 92; the pushing cylinder 6 is started to push the horizontal moving component 7 to move horizontally along the guide rod 10 to adjust the front and rear position of the grinding wheel 92; the second motor 74 is started, and the second motor 74 drives the mounting screw 73 to rotate, which drives the sliding seat 72 to slide laterally in the groove of the strip seat 71, so as to achieve precise adjustment of the left and right position of the grinding wheel 92.

[0033] To adjust the grinding angle, start the motor 87. The motor 87 drives the worm gear 86 to rotate. The worm gear 86 meshes with the worm wheel 84, which drives the rotating shaft 82 to rotate within the rotating frame 81. This, in turn, drives the grinding assembly 9 to rotate through the sleeve block 83 until the grinding wheel 92 reaches the preset angle.

[0034] Finally, the grinding motor 93 is started, which drives the grinding wheel 92 to rotate at high speed to grind and polish the tool. Each adjustment mechanism can be adjusted in real time according to the grinding situation to ensure that the grinding effect is uniform and precise.

[0035] Working principle: The present invention achieves stable clamping of the tool through clamping component 3, and achieves precise positioning of grinding wheel 92 in three-dimensional space by using lifting component 4, pushing cylinder 6 and transverse component 7. The grinding angle is flexibly adjusted by angle adjustment component 8, and combined with high-speed grinding by grinding component 9, the tool is efficiently and finely ground and polished, which solves some defects of existing devices.
