[0019] Example: See Figures 1 to 4 As shown, a feeding mechanism for visual inspection of pipe joints includes a visual inspection table, a circular rotating workstation 1 is arranged on the visual inspection table, a horizontal longitudinal conveyor belt 2 is arranged on the left side of the rotating workstation 1, a feeding mechanism 3 is arranged between the conveyor belt 2 and the rotating workstation 1, and the feeding mechanism 3 includes a semicircular ring-shaped positioning seat 31, and the positioning seat 31 is located directly above the outer ring of the rotating workstation 1; the two ends of the positioning seat 31 are respectively formed with a horizontal rear baffle 311 and a front baffle 312, and the rear baffle 311 and the front baffle 312 on the left side of the rotating workstation 1 are respectively formed There is a support plate 313 extending downward and in an L shape, and a rectangular slot 314 is formed on the support plate 313, and the conveyor belt 2 is inserted into the slot 314 of the support plate 313; the upper end surface of the front baffle plate 312 is formed with an input slot 315 opposite to the conveyor belt 2, and a horizontal rectangular support plate 32 is fixedly connected between the rear baffle plate 311 and the front baffle plate 312 on the right side of the input slot 315; the bottom of the support plate 313 is formed with a plurality of mounting holes 316, and bolts are inserted into the mounting holes 316, and the support plate 313 is fixedly connected to the visual inspection table by bolts;
[0020] A longitudinal push plate 35 is inserted between the rear baffle 311 and the front baffle 312 on the left side of the input slot 315, and a longitudinal cylinder mounting plate 33 is fixedly connected to the rear baffle 311 and the front baffle 312 on the left side of the push plate 35, and a longitudinal feed cylinder 34 is fixedly connected to the cylinder mounting plate 33, and the piston rod of the feed cylinder 34 passes through the cylinder mounting plate 33 and is fixedly connected to the push plate 35, and a transverse guide rod 36 is fixedly connected to the push plate 35, and the guide rod 36 is inserted on the cylinder mounting plate 33.
[0021] The conveyor belt 2 includes side support plates on both sides and an annular belt between the side support plates. A driving roller and a driven roller are respectively inserted at both ends of the annular belt. The two ends of the driving roller and the driven roller are respectively inserted on the side support plates. The side support plates on the conveyor belt 2 are respectively fixed to the inner side walls on both sides of the slot 314. The input slot 315 is located directly above the annular belt.

[0023] The maximum distance between the right end face of the support plate 32 and the inner wall of the positioning seat 31 is not less than the diameter of the inner wall of the positioning seat 31. Because the pipe joint needs to be output through the lower part of the positioning seat 31 when it is pushed to the positioning seat 31, the support plate 32 cannot interfere with the output of the pipe joint.

[0025] A longitudinal support plate 320 is inserted and fixed between the left sides of the support plates 313 , and the support plate 320 abuts against the lower end surface of the receiving plate 37 .
[0026] Preferably, a rubber buffer pad 310 is fixedly connected to the upper end surface of the receiving plate 37 , and the lower end surface of the receiving plate 37 is located on the upper side of the upper end surface of the rotary workstation 1 .
[0027] Working principle: The utility model is a feeding mechanism for visual inspection of pipe joints. The structure of the feeding mechanism is as follows: Figure 3 , Figure 4 As shown, the position of the pipe joint to the rotating table 1 is accurately positioned based on the positioning seat 31 arranged above the rotating table 1;
[0028] The specific working method is that the pipe joint is conveyed to the feeding mechanism 3 through the conveyor belt 2, the conveyor belt 2 enters the feeding mechanism 3 through the input slot 315, and then stops moving due to the restriction of the rear baffle 311, and then the feeding cylinder 34 is started, and the feeding cylinder 34 drives the pushing plate 35 to push the pipe joint to the right, and finally pushes it into the positioning seat 31, and the bottom of the positioning seat 31 is empty, so the pipe joint in the positioning seat 31 can fall onto the rotating workstation 1 and detach from the positioning seat 31.
