[0025] The working principle of the clamping mechanism 2 is as follows: the push rod of the telescopic cylinder 20 is extended to push the push block 22 to move, driving the connecting rod 23 to move to the left and rotate outward at the same time, and the clamping plate 24 is translated outward along the direction of the limit groove 240; the metal parts move along the transmission mechanism 4, and after being blocked by the fixed blocking frame 21, the push rod of the telescopic cylinder 20 is retracted to pull the push block 22 to move, driving the connecting rod 23 to move to the right and rotate inward at the same time, and the clamping plate 24 is translated inward along the direction of the limit groove 240, completing the process of centering and clamping the workpiece.

[0026] The conveying mechanism 4 includes: a conveying belt 40 and an accumulation roller machine, and the accumulation roller machine includes: a roller 41, a roller main shaft 42, a side plate 43, a sprocket assembly 44, an adjustment assembly 45, a transmission chain 46, and a motor 47. The conveying belt 40 is sleeved on the outside of the roller 41, and the roller 41 is rotatably connected to the roller main shaft 42. One end of the roller main shaft 42 is rotatably connected to the sprocket assembly 44, and the other end is rotatably connected to the adjustment assembly 45. The outermost ends of both sides of the roller main shaft 42 are fixedly mounted on the side plate 43, and the sprocket assemblies 44 are staggeredly connected through the transmission chain 46. The rightmost sprocket assembly 44 is connected to the output end of the motor 47 through a chain transmission.

[0027] The working principle of the conveying mechanism 4 is as follows: the motor 47 drives the sprocket assembly 44 to rotate, drives the roller 41 to rotate, and drives the conveying belt 40 to transport the metal parts.

[0028] The sprocket assembly 44 includes a double-row sprocket 440, a ball bearing 441, a friction plate 442, and a first nut 443.

The roller main shaft 42 has threads at both ends. The first nut 443 is screwed to the roller main shaft 42 and abuts against the outer side of the double-row sprocket 440.

[0029] The working principle of the sprocket assembly 44 is as follows: After the metal components are blocked by the fixed baffle 21 and stop moving, the resistance received by the roller 41 is greater than the frictional force between the friction plate 442 and the double-row sprocket 440, and the double-row sprocket 440 only idles.

[0031] The working principle of the adjustment assembly 45 is as follows: By rotating the second nut 452, the tightness of the compression spring 450 can be adjusted, thereby affecting the magnitude of the frictional force between the friction plate 442 and the double-row sprocket 440 in the sprocket assembly 44.

[0032] A protective pad 241 is fixedly installed on the inner side of the clamping plate 24.

[0033] When the present utility model is in use: First, adjust the clamping mechanism 2 to a specified height through the lifting cylinder 5, turn on the motor 47, the roller 41 rotates to drive the conveyor belt 40 to transport the metal components. When the metal components reach a predetermined position and are blocked by the fixed baffle 21, the double-row sprocket 440 enters the idling mode. Retract the push rod of the telescopic cylinder 20 to drive the clamping plate 24 to clamp the metal components. Operate the truss-type grinding mechanism 3 to process the surface of the metal components. After the processing is completed, extend the push rod of the telescopic cylinder 20 to move the clamping plate 24 to both sides. Start the lifting cylinder 5 to raise the clamping mechanism, and the roller 41 resumes rotation to drive the conveyor belt 40 to continue transporting the metal components to complete the blanking.

[0034] The above has made an exemplary description of the present utility model in conjunction with the drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the present utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
