DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Reference Figure 1-3The utility model provides a visual inspection and positioning device for perforated pipes and a step ring installation device, which is characterized by comprising a chain conveyor 10 and a visual positioning mechanism 20 and a material feeding and pushing mechanism 30 arranged on both sides of the chain conveyor 10, wherein the visual positioning mechanism 20 comprises a detection platform 21, a bracket 22 fixed on the detection platform 21, and a camera 23 fixed on the bracket 22;

[0016] The feeding and pushing mechanism 30 includes a feeder platform 31, an optical axis guide rail group 32 erected on the feeder platform 31, an operating table 33 sleeved on the optical axis guide rail group 32, a feeding slide plate 34 erected on the operating table 33, a feeding guide rail 35 and a feeding cylinder 36 arranged on the operating table 33, and a clamping claw cylinder 37 arranged on the feeding guide rail 35. An electric push rod 39 is provided between the feeder platform 31 and the operating table 33 for controlling the vertical movement of the operating table 33. The feeding slide plate 34 is used to place a step ring. The feeding slide plate 34 is close to the chain conveyor 10. A step ring outlet is provided at the contact position between the feeding slide plate 34 and the operating table 33. A slidable blocking plate 38 is placed at the step ring outlet of the feeding slide plate 34. The claw mouth of the clamping claw cylinder 37 faces the outlet of the feeding slide plate 34 and is controlled to move in translation by the feeding cylinder 36.

[0017] In actual use, the perforated pipe is placed upright on the chain conveyor 10, and the step ring is placed on the feeding slide plate. When the perforated pipe comes to the detection and positioning mechanism 20, the cameras 23 located at both ends of the perforated pipe will take pictures of the perforated pipe, and the position of the center hole will be detected by the visual system to check the concentricity of the hole on the perforated pipe; if the perforated pipe is unqualified, the chain conveyor 10 directly transports the perforated pipe away and skips the loading and pushing mechanism 30; if it is qualified, it is transported to the loading and pushing mechanism 30, and the height of the operating table 41 is first adjusted by mobilizing the electric push rod 44 , so that the step ring outlet of the feeding slide plate 34 is facing the hole center of the perforated pipe. At this time, the jaw cylinder 37 moves toward the perforated pipe under the action of the feeding cylinder 36, and the jaws of the jaw cylinder 37 extend into the step ring and extend to both sides. At this time, the step ring at the outlet will be clamped, and the blocking plate 38 descends. The clamped step ring will not fall off. The feeding cylinder 36 continues to work and sends the step ring on the jaw cylinder 37 to the perforated pipe for assembly. After that, the jaws shrink and do not contact the step ring. The jaws of the jaw cylinder 37 leave the perforated pipe and return to the initial position.

[0018] The clamping cylinder 37 is provided with at least two clamping jaws extending outward, and the front end of the clamping jaw is provided with an arc surface matching the inner ring of the step ring. When the clamping cylinder 37 delivers the step ring to the hole of the feeding pipe, the step ring will not slide on the clamping jaw during the tightening operation, causing assembly failure.

[0019] The chain conveyor 10 is also provided with a holder, on which the end of the perforated pipe with the hole is placed upwards, so as to avoid the perforated pipe being pushed down due to the different forces on the two sides of the feeding cylinders on both sides of the chain conveyor 10 during the tightening operation.

[0020] The feeding slide plate 34 is provided with a T-shaped groove for accommodating a step ring, and the operating plate 33 is provided with a notch, and a push rod cylinder is provided on the notch. The push rod of the push rod cylinder is connected to the blocking plate and is used to control the up and down movement of the blocking plate.

[0021] In actual use, the perforated pipes are arranged in sequence on the chain conveyor 10, and the step rings are placed on the loading guide rail 420. When the perforated pipes come to the detection and positioning mechanism 30, the cameras 31 located at both ends of the perforated pipes will take pictures of the perforated pipes, and the position of the center hole will be detected by the visual system to check the concentricity of the holes on the perforated pipes. If the perforated pipes are unqualified, the chain conveyor 10 will directly transport the perforated pipes away and skip the loading and pushing mechanism 40. If they are qualified, they will be transported to the loading and pushing mechanism 40, and the height of the operating table 41 will be adjusted by mobilizing the electric push rod 44 so that the material taking port 421 is facing the perforated pipes. The hole center of the pipe, at this time, the jaw cylinder 430 moves toward the direction of the perforated pipe under the action of the tightening cylinder 45, and the jaws of the jaw cylinder 430 extend into the inside of the step ring and pneumatically extend to both sides, at this time, the step ring will be clamped, and under the action of the blocking cylinder 423, the blocking plate 422 descends. Since the jaw cylinder 430 has clamped the step ring before, the step ring will not fall off, and the tightening cylinder 45 continues to work, and the step ring on the jaw cylinder 430 is sent to the perforated pipe for assembly. After that, the jaw shrinks and does not contact the step ring, driving the tightening cylinder 45 to make the jaw cylinder 430 leave the perforated pipe and retreat to the initial position.

[0022] The device of the utility model can also be used in conjunction with a loading tray. The vibrating loading tray is placed at the entrance of the chain conveyor 10. Through vibration, the perforated pipes are evenly arranged and enter the chain conveyor 10 in sequence, reducing the labor intensity of workers.

[0023] Working principle: The utility model detects and locates the hole position of the perforated pipe through the detection and positioning mechanism 20. The perforated pipe that does not meet the requirements is directly sent away by the chain conveyor 10, and the one that meets the requirements is sent to the feeding and pushing mechanism 30. First, the electric push rod lifts the operating table to a suitable position so that the step ring outlet of the feeding slide plate 34 is directly opposite to the hole position of the perforated pipe. The step ring on the feeding guide plate 34 is clamped by the claw cylinder 37, and under the action of the feeding cylinder 36, it is sent to the perforated pipe for assembly. The utility model has high working efficiency and is safe and reliable.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
