[0028] A titanium rod surface polishing grinding machine comprises the following steps:

[0029] S1, titanium rod clamping:

[0030] The first motor is driven to synchronously rotate the two rotating rods according to the output torque, so as to provide power for the clamping action, the rotating power of the first motor is transmitted to the rotating blocks according to the two rotating rods, the four arc-shaped plates are pushed to swing according to the rotation of the two rotating blocks, so that the rotating motion is converted into the moving power of the clamping seat, the power of the two rotating blocks is transmitted according to the four arc-shaped plates, the rotating motion is converted into the horizontal sliding of the four connecting blocks, so that the four clamping seats are driven to approach the titanium rod, directly contact the titanium rod and exert clamping force, and the titanium rod is fixed;

[0031] S2, titanium rod polishing:

[0032] The output end of the third motor is fixed with the upper side of the spur gear, one of the spur gears is driven to rotate according to the third motor, and the outer gear ring is meshed with the plurality of spur gears, the power is transmitted to the plurality of polishing grinding wheels according to the plurality of spur gears, the grinding wheels are driven to rotate to realize polishing, the surface abrasive is rubbed with the titanium rod to remove surface defects, and polishing is realized.

[0033] S3, position height adjustment:

[0034] The second motor drives the lead screw to rotate, causing the nut to move up and down axially as the lead screw rotates. This linear motion is transmitted to the connecting seat, enabling the left and right position adjustment of the lower grinding mechanism. The height of the rotating shell is precisely adjusted according to the telescopic movement of the electric push rod, further adjusting the distance between the grinding wheel and the titanium rod. Two telescopic rods assist the electric push rod in supporting the rotating shell, preventing it from tilting or shaking during movement or operation, thus enhancing the stability of the grinding mechanism.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1. The first motor drives two rotating rods to rotate synchronously based on their output torque. These rods, in turn, drive two rotating blocks to rotate, which in turn push four arc-shaped plates to swing. This converts the rotational motion into the movement of the clamping seats, bringing them closer to the titanium rod. The clamping seats then directly contact the titanium rod and apply clamping force, thus fixing it in place. A third motor drives one of the spur gears to rotate, while the external gear ring meshes with multiple spur gears. These gears transmit power to multiple grinding wheels, causing them to rotate and perform grinding. The friction between the surface abrasive and the titanium rod removes surface imperfections, achieving polishing and enhancing the clamping and fixing effect. This method can clamp titanium rods of different diameters, resolving issues of loose or excessive clamping, preventing the titanium rod from shaking during grinding, improving the polishing accuracy, and enhancing the synchronous grinding of the titanium rod surface. This ensures uniform grinding of the titanium rod surface, avoiding over- or under-polishing in certain areas, thereby improving the overall polishing quality.

[0037] 2. The second motor drives the lead screw to rotate, so that the nut moves up and down along the axis when the lead screw rotates, transmitting linear motion to the connecting seat to realize the left and right position adjustment of the lower grinding mechanism. The height of the rotating shell is precisely adjusted by the telescopic action of the electric push rod. The two telescopic rods assist the electric push rod in supporting the rotating shell to prevent the rotating shell from tilting or shaking when moving or working, thus enhancing the stability of the grinding mechanism.

[0038] 3. By having two inclined plates tilted simultaneously, the debris generated during grinding is guided to slide down the inclined surface and away from the clamping area, making it easier to collect and clean the debris. Two shielding nets block the debris and dust that splash during grinding, reducing dust diffusion. Attached Figure Description
