Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, and in particular to a steel stamp marking device for the outer wall of a water conservancy pipeline. Background Technology

[0002] In water conservancy projects, oil and gas transportation, and municipal pipeline network construction, standardized marking of steel pipelines is a core component of the quality traceability system. According to industry standards (such as GB / T 9711 and SHT 3543), the outer wall of the pipeline must be permanently marked with a steel stamp containing information such as pipe diameter, material, and production batch. Traditional marking technologies suffer from the following key bottlenecks:

[0003] Manual positioning is inefficient.

[0004] Existing equipment mostly uses fixed pneumatic stamping heads or handheld laser marking machines. During operation, the position of each pipe needs to be manually adjusted, and the starting point of the mark needs to be visually aligned. Actual measurement data shows that positioning a single pipe takes more than 30% of the overall operation cycle, and the rolling of the pipe can easily cause positioning deviation, resulting in the marking position being out of tolerance.

[0005] The process is severely disrupted, and the traditional workflow presents a breakpoint pattern of "processing-waiting-clamping": the operator is idle when the equipment is running, and the next pipe needs to be hoisted and positioned again after the equipment stops.

[0006] Industry research indicates that this model results in insufficient overall equipment efficiency (OEE).

[0007] The efficiency of human-machine collaboration is insufficient. Although some equipment has pre-installed workstations, the lack of a position sensing and linkage system renders the pre-installation function ineffective because the pre-installed pipeline status requires manual visual inspection and cannot form an interlocking response with the main control system. Therefore, a steel stamp marking device on the outer wall of water conservancy pipelines is proposed to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0009] Therefore, one objective of this utility model is to provide a steel stamp marking device for the outer wall of water conservancy pipelines to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0010] To achieve the above objectives, one embodiment of the present invention provides a steel stamp marking device for the outer wall of a water conservancy pipeline, comprising a main board, a first servo motor, a lead screw, and a first track. The first servo motor is fixedly connected to the front of the main board, and the lead screw is fixedly connected to the output end of the first servo motor. A slide is threadedly connected to the outer surface of the lead screw. The first track is fixedly connected to the front of the main board, and the upper part of the slide is movably connected to the first track.

[0011] A second servo motor is fixedly connected to the inner side of the slide block, and a lead screw is fixedly connected to the output end of the second servo motor. A slider is threadedly connected to the outer surface of the lead screw, and a second track is fixedly connected to the bottom of the slide block.

[0012] The slider is movably connected to the second track, and a laser head is fixedly connected to the bottom of the slider;

[0013] A reduction motor is provided on the lower side of the laser head, and a three-jaw chuck is fixedly connected to the output end of the reduction motor. The workpiece is clamped at the center of the three-jaw chuck.

[0014] A positioning frame is provided on one side of the three-jaw chuck, and the positioning frames are connected by a crossbeam;

[0015] The positioning frame is V-shaped, with a bracket fixedly connected to one side of the positioning frame, and a photoelectric switch fixedly connected to the end of the bracket, with the detection end of the photoelectric switch facing upwards.

[0016] Preferably, in any of the above solutions, the first servo motor and the second servo motor are both installed horizontally, and the first track and the second track are both made of stainless steel.

[0017] Using the above technical solution: This device is specifically designed for marking on the outer wall of steel pipes.

[0018] This device consists of three parts. The first part is the laser marking part, which is composed of a main board, a first servo motor, a lead screw, a first track, a slide, a second servo motor, a slider, a second track, and a laser head structure. The laser head emits a laser beam to mark the surface of the pipe. The laser head can move back and forth and left and right.

[0019] The second part is the pipe fixing part, which consists of a geared motor and a three-jaw chuck structure. The three-jaw chuck is a conventional structure. The handle makes the jaws close and clamp the pipe. The three-jaw chuck can rotate. With the laser head, it can achieve full marking on the outer wall of the pipe.

[0020] The third part is the pipe prefabrication station, which consists of a V-shaped positioning frame, a support, and a photoelectric switch. Several positioning frames are set up on one side of the three-jaw chuck as prefabrication stations. An infrared photoelectric sensor, i.e. a photoelectric switch, is installed at the entrance of the laser processing area in front of the chuck. The operator can place the next steel pipe to be marked on the prefabrication station while processing the current steel pipe, thus realizing assembly line operation.

[0021] The sensor is used to detect whether the steel pipe has been installed in place. Once the operator has installed the steel pipe in place, the sensor will no longer detect the pipe and will prompt the operator to start marking (or connect the safety door lock / start conditions).

[0022] It can reduce waiting time and improve the pace. The pre-loading design and photoelectric switch can improve human-machine collaboration efficiency.

[0023] Preferably, in any of the above embodiments, the slider and laser head can be adjusted in position forward, backward, left, and right, and the three-jaw chuck has an adjustment handle.

[0024] The device consists of the following components: For the laser marking section, a first servo motor is fixed to the front of the main board, and its output end is connected to a lead screw. A slide block is threaded onto the outer surface of the lead screw. A first track is fixed to the front of the main board, and the slide block slides along the first track (achieving X-axis movement). A second servo motor is fixed to the inner side of the slide block, and its output end is connected to a lead screw. A slider is threaded onto the outer surface of this lead screw. A second track is fixed to the bottom of the slide block, and the slider slides along the second track (achieving Y-axis movement). A laser head is fixed to the bottom of the slider, used to emit a laser beam to form a permanent steel stamp mark on the pipe surface.

[0025] Pipe fixing section: A geared motor is installed below the laser head, and the output end of the geared motor is connected to a three-jaw chuck via a flange. The three-jaw chuck adjusts the jaws to hold the workpiece (hydraulic pipeline) via a handle. Critical position constraint: The center point of the workpiece held by the three-jaw chuck is located directly below the laser head.

[0026] Pipe prefabrication station section: At least one set of V-shaped positioning frames is installed on one side of the three-jaw chuck, and the positioning frames are connected by a crossbeam. The V-shaped structure can adapt to different pipe diameters and provide pre-support. Supports are fixed to the sides of the positioning frames, and photoelectric switches (infrared type) are installed at the ends of the supports. The detection end of the photoelectric switch faces upwards to detect whether the pipe has entered the processing position. Core linkage design: The detection signal of the photoelectric switch is connected to the PLC module, and a prompt signal is triggered when no pipe is detected.

[0027] Preferably, in any of the above solutions, the three-jaw chuck is connected to the output end of the geared motor via a flange, and the positioning frame is made of stainless steel.

[0028] This device achieves its positioning detection through a combination of a prefabricated V-shaped positioning frame and a photoelectric switch.

[0029] Continuous flow operation: The operator can place the next pipe into the prefabrication station while the current pipe is being marked.

[0030] Zero-wait positioning: The moment the pipe is pushed into the processing position, the photoelectric switch detects that the obstruction has disappeared → automatically triggers the PLC to prompt the operator to start marking.

[0031] Anti-misoperation mechanism: The photoelectric switch only releases the start signal when the pipeline completely covers the three-jaw chuck, avoiding dry operation.

[0032] Preferably, in any of the above solutions, the workpiece positioned by the three-jaw chuck is located below the laser head.

[0033] The working steps of this device are as follows: Pre-fabricate the pipe, and the operator places the pipe to be marked horizontally on the V-shaped positioning frame, aligning the pipe axis with the center of the three-jaw chuck.

[0034] The advance trigger pushes the pipe forward into the processing area. When the pipe is completely out of the photoelectric switch detection area (i.e., completely covers the chuck): the photoelectric switch sends an "unobstructed" signal to the PLC → the PLC triggers the audible and visual prompt (or enables the start button).

[0035] Positioning and marking: After operator confirmation and prompting, the following steps are executed: ① Rotate the handle to clamp the pipe with the three-jaw chuck; ② Start the reduction motor to drive the pipe to rotate at a constant speed; ③ The first servo motor drives the slide to move along the first track (X-axis); ④ The second servo motor drives the slider to move along the second track (Y-axis); ⑤ The laser head marks the outer wall of the pipe according to the preset trajectory.

[0036] After the cycle resets and marking is completed: ① Release the three-jaw chuck to remove the pipe; ② Push the next pipe from the prefabrication station into the processing station; ③ Trigger the photoelectric switch again → repeat the steps.

[0037] Preferably, in any of the above schemes, the positioning frames are arranged in pairs, and the PLC module is connected to provide a prompt when the photoelectric switch fails to detect the workpiece.

[0038] Core design features of this device: Significantly improved efficiency: Prefabricated workstations eliminate loading and unloading waiting time, and photoelectric switches automatically trigger start commands, shortening operation intervals. Guaranteed accuracy: V-shaped positioning frames constrain the initial position of the pipes, and photoelectric switches confirm complete positioning, avoiding human visual error. Optimized human-machine collaboration: Audible / visual prompts clearly define operation nodes, reducing labor intensity.

[0039] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0040] This steel marking device for the outer wall of water conservancy pipelines features a prefabrication station section, consisting of a V-shaped positioning frame, a support, and a photoelectric switch. Several positioning frames are positioned on one side of a three-jaw chuck as prefabrication stations. An infrared photoelectric sensor (i.e., a photoelectric switch) is installed at the entrance of the laser processing area in front of the chuck. The operator can place the next pipe to be marked onto the prefabrication station while processing the current pipe, enabling continuous operation. The sensor detects whether the pipe is properly inserted. Once the operator has inserted the pipe, the sensor no longer detects it and prompts the operator to start marking (or connect a safety lock / start condition). This reduces waiting time and improves efficiency. The pre-loading design and photoelectric switch enhance human-machine collaboration efficiency.
