The side plate group includes an inner plate and an outer plate that are hinged to each other. The outer plate is connected to the rotating table, the inner plate is connected to the support plate, and the inner plate is provided with teeth that mesh with the rack;

The buffer structure has one end connected to the support plate and the other end connected to the rotating table;

The base is provided with a driver that drives the rotating table to rotate.

The fine-tuning structure is used to adjust the angle of the clamping mechanism, thereby adjusting the angle of the blade so that its inclined parts can be easily polished. The angle adjustment is a combination of two adjustment methods, one is horizontal adjustment, and the angle is adjusted by a rotating table The adjustment is completed in conjunction with the driver. The driver drives the rotary table to rotate, so that all the structures on the rotary table rotate together, and finally completes the horizontal rotation of the blade. The other is the angle adjustment in the vertical direction, driven by the second electric push rod. The sliding plate slides, and the sliding of the sliding plate drives the movement of the rack, and through the cooperation of the rack and the teeth, the support plate rotates, thereby completing the angle adjustment in the vertical direction. Since the angle adjustment in the vertical direction is affected by gravity and pressure has a greater impact, which will lead to unstable adjustment and affect the accuracy of adjustment. In this application, a buffer structure is set up to improve the stability of adjustment.

Further, the buffer structure includes:

The pressure rod includes a rod body, one end of the rod body is hinged with the support plate, and the other end extends toward the rotating table;

One end of the pressure rod body close to the force rod extends into the buffer cavity and the two form a telescopic structure. When the second electric push rod pushes the sliding plate to move, the inner plate drives the support plate along the hinge point of the inner plate and the outer plate. Rotate, at this time, the pressure rod and the force rod will expand and contract and buffer the angle adjustment process, thereby ensuring the stability of the angle adjustment and preventing the fourth base from being under excessive pressure, resulting in unstable adjustment.

Wherein, the telescopic end of the damping rod is connected to the bottom of the second buffer plate.

The angle adjustment in the vertical direction is in two directions, one upward and the other downward. With different angle adjustments, the force rod and the pressure rod will also change between stretching and contraction. When the adjustment angle is downward When, that is, the output shaft of the electric push rod is in an extended state, the pressure rod and the force rod will be in a contracted state, and the rod body drives the first buffer plate to move toward the second buffer plate through the connecting rod, so that the first buffer plate moves in the direction of the first buffer plate. The buffer spring and the second buffer spring are squeezed to play a buffering role. At the same time, when the second buffer plate is squeezed, the telescopic end of the damping rod retracts and plays a damping and buffering role. Through the two buffer springs and the damping rod Used together, the buffering effect is further improved and the angle adjustment process is more stable;

When the adjustment angle is upward, that is, the output shaft of the electric push rod is in a retracted state. At this time, the pressure rod and the force rod will be in a stretched state. The rod body drives the first buffer plate away from the second buffer plate through the connecting rod. When the plate moves in the direction, the first buffer spring and the second buffer spring are stretched, and then play a buffering role. At the same time, driven by the second buffer plate, the telescopic end of the damping rod stretches out and plays a damping and buffering role. The combined use of two buffer springs and damping rods further improves the buffering effect, makes the angle adjustment process more stable, and ensures the stability of the adjustment of the two angles in the vertical direction of the holding mechanism.

Among them, a plurality of limiters are also provided on the force-bearing rod, and the guide rod is arranged in the limiter and is slidingly connected with the limiter.

Since the adjustment in the vertical direction is always affected by pressure, long-term and multiple adjustments will inevitably be affected by lag, and lag will cause the angle adjustment to be inaccurate. In order to further improve the accuracy of the angle adjustment, this The application also provides an inner axial deformation component and an outer axial deformation component. The inner axial deformation component and the outer axial deformation component here are elastic discs that can be deformed to a certain extent along the axial direction of the connecting rod. Deformation, when the pressure rod and the force rod are stuck during angle adjustment, the inner axial deformation component and the outer axial deformation component can provide a certain redundancy for the movement of the connecting rod in the axial direction through their own deformation, making it It can avoid the negative effects caused by stuck, so that the angle can be adjusted accurately. In addition, when the pressure rod and the force rod cannot be telescopic, forced angle adjustment may cause the internal structure of the pressure rod and the force rod to be damaged. The inner axial deformation component and the outer axial deformation component can provide a certain buffer for this angle adjustment, protect the internal structure, and avoid damage to the internal structure due to forced angle adjustment.

At the same time, in this application, by arranging multiple guide rods and arranging multiple limiters on the force-bearing rods that slide with the guide rods, it can play a limiting role and can also play a guiding role. Here, The limiter is a linear bearing, which can reduce the friction force of the pressure rod and the force rod when they expand and contract, and reduce the chance of jamming.

Further, the first buffer plate and the second buffer plate are provided with guide slide blocks, and the inner wall of the buffer cavity is provided with a guide chute that matches the guide slide blocks.

By arranging guide sliders on the first buffer plate and the second buffer plate, and arranging matching guide slides on the inner wall of the buffer cavity, the first buffer plate and the second buffer plate can move along the guide slider through the guide sliders. The guide chute moves to limit the movement of the first buffer plate and the second buffer plate, and also plays a limiting role to effectively prevent the first buffer plate and the second buffer plate from flipping or deflecting when moving. .

1. By setting up a rolling mechanism, the blade on the blade can be polished, plastically deforming the surface metal of the blade, cold hardening the surface structure and thinning the grains, forming a dense fiber shape, and forming a residual stress layer. Improve the hardness and strength, effectively improving the overall wear resistance and corrosion resistance of the blade. The clamping mechanism is used to clamp the workpiece to be polished, and the rotating mechanism is used to adjust the position and angle of the clamping mechanism. By adjusting the clamp The holding mechanism is used to adjust the position and angle of the workpiece so that the workpiece can be tilted, such as the blade of a knife, which can also be easily polished;

2. One end of the pressure rod body close to the force rod extends into the buffer cavity and the two form a telescopic structure. When the second electric push rod pushes the sliding plate to move, the inner plate drives the support plate along the gap between the inner plate and the outer plate. The hinge point rotates. At this time, the pressure rod and the force rod expand and contract and buffer the angle adjustment process, thereby ensuring the stability of the angle adjustment and preventing the fourth base from being overly pressured and causing unstable adjustment;

3. In order to further improve the accuracy of angle adjustment, this application also provides an inner axial deformation component and an outer axial deformation component. The inner axial deformation component and the outer axial deformation component here are elastic discs that can be moved along the Deform to a certain extent in the axial direction of the connecting rod. When the pressure rod and the force rod are stuck during angle adjustment, the inner axial deformation component and the outer axial deformation component can deform into the connecting rod axis through their own deformation. Movement in the direction provides a certain amount of redundancy, allowing it to avoid the negative effects of lag, allowing the angle to be accurately adjusted.
