In addition, when the number of screws to be processed is large, the processing process may also increase the labor intensity. Therefore, the efficiency of processing screws using traditional processes is low.

DETAILED DESCRIPTION

[0029] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0030] As attached Figure 1 -Attached Figure 3As shown, the present invention is a through-hole plug rod processing device, including a feeding component, a feeding ramp 2 is arranged on a component support 1 of the feeding component, an opening 3 is arranged at one end of the feeding ramp 2, a feeding channel 4 is arranged on the component support 1 near the opening 3, the feeding channel 4 is a concave structure, a pushing component 5 is arranged at one end of the feeding channel 4, the other end of the feeding channel 4 is close to one end of the processing component 5, the processing component 5 is provided with a first processing wheel 6 and a second processing wheel 7, the first processing wheel 6 and the second processing wheel 7 are respectively connected to a driving motor, and a receiving component 8 is arranged at the other end of the processing component 5. The above structure proposes an improved technical solution to the deficiencies in the prior art. When setting up the structure, a feeding component is set, and the feeding component is used to convey the screw portion 14 to be processed that needs to be threaded, that is, it is used to convey the screw portion 14 to be processed from the feeding ramp 2 through the opening portion 3 to the feeding channel 4. The feeding ramp 2 is an inclined structure, which is convenient for the screw portion 14 to be processed to automatically roll down and fall through the opening portion 3, thereby falling onto the feeding channel 4. The feeding channel 4 is a straight structure, which is used to carry the fallen screw portion 14 to be processed. The feeding channel 4 is a concave structure, and a pushing component 5 is set at one end of the feeding channel 4, and the other end of the feeding channel 4 is close to one end of the processing component 5. After the screw portion 14 to be processed falls into the feeding channel 4, under the thrust of the pushing component 5, the screw portion 14 to be processed is fed into the processing component for thread processing. The processing component 5 is provided with a first processing wheel 6 and a second processing wheel 7. There is a gap between the first processing wheel 6 and the second processing wheel 7, which is convenient for the screw rod 14 to be processed to pass through. The first processing wheel 6 and the second processing wheel 7 are respectively connected to driving motors. Each driving motor drives a corresponding processing wheel to rotate, thereby controlling the screw rod to be processed to complete the thread processing in the process of passing through the first processing wheel 6 and the second processing wheel 7. After the processing is completed, the screw rod to be processed leaves the first processing wheel 6 and the second processing wheel 7. A receiving component 8 is provided at the other end of the processing component 5, and the screw rod to be processed that leaves the first processing wheel 6 and the second processing wheel 7 falls on the receiving component to complete the processing. The device of the present invention aims at the problems of poor manufacturing process and long processing time of through-hole plug rods in the prior art, which leads to low processing efficiency and high labor intensity of workers, and proposes a new through-hole plug rod structure, through-hole plug rod processing device and through-hole plug rod processing method. The automation degree of thread processing of through-hole plug rods is improved, and the processing time of screw rods is reduced, thereby improving processing efficiency and reducing labor intensity of workers. The through-hole plug rod processing device of the present invention has a simple structure, improves the degree of automation during through-hole plug rod processing, reduces the working hours for through-hole plug rod thread processing, improves processing efficiency, and reduces the labor intensity of workers.

[0031] The height of the feeding ramp 2 near the opening 3 is lower than that of the other end of the feeding ramp 2, and a flip limiter 9 is provided at the end of the feeding ramp 2 near the opening 3. With the above structure and the setting of the feeding ramp, the screw part 14 to be processed can continue to roll down on the feeding ramp, ensuring that it can fall into the feeding channel without external force. The setting of the flip limiter 9 can block other screw parts 14 to be processed after one screw part 14 to be processed falls, ensuring that they will not fall, so that each screw part 14 to be processed can be processed in sequence.

[0032] The feeding ramp 2 is provided with limit plates 10 on the other three sides except one end of the opening 3. In the above structure, the limit plates on the three sides are protruding from the feeding ramp, realizing the limit on the three sides, preventing the screw part 14 to be processed from falling from the three sides, and can only fall from the opening.

[0033] The flip limit component 9 includes a connecting rod 11, on which a limit end rod 12 perpendicular to the connecting rod 11 is arranged, one end of the connecting rod 11 is movably connected to the limit plate 10 on one side, and the other side of the connecting rod 11 is movably connected to the limit plate 10 on the other side, and a telescopic flip component 17 is arranged outside the limit plate 10 on one side, and the telescopic flip component 17 is connected to the flip short rod 13 at the end of the connecting rod 11. In the above structure, the connecting rod is movably connected to the limit plate. When the telescopic flip component 17 is extended and retracted, it acts on the flip short rod 13, and drives the connecting rod to rotate a certain angle through the flip end rod 13, so that the limit end rod is lifted upward, and a screw rod to be processed can fall from the opening to the feeding channel, and then the telescopic flip component shrinks and acts on the flip short rod, and drives the connecting rod 11 to rotate a certain angle through the flip end rod 13, so that the limit end rod falls downward, blocking the screw rod 14 to be processed on the feeding ramp 2 from falling. In this way, the screw portion 14 to be processed can be controlled to fall down for processing according to the processing rhythm.

[0034] The first processing wheel 6 and the second processing wheel 7 are respectively provided with thread structures, and the thread structures on the first processing wheel 6 and the second processing wheel 7 have the same rotation direction. With the above structure, the first processing wheel 6 and the second processing wheel 7 can reliably complete the processing of the screw part to be processed when they rotate.

[0035] The driving motor, the material pushing component 5, and the telescopic flipping component 17 are connected to the control component respectively. With the above structure, the control component can reliably realize the start and stop actions of the above components and realize control.

[0036] The telescopic flipping component 17 is a cylinder or an oil cylinder, and the pushing component 5 is a cylinder or an oil cylinder. With the above structure, the telescopic flipping component 17 can be conveniently and reliably telescoped, and the connecting rod 11 is driven to rotate a certain angle by the flipping end rod 13, and the limit end rod is rotated. The pushing component 5 can be conveniently telescoped, and the screw part 14 to be processed can be fed when it is extended. The pushing component 5 is retracted and reset, and can be used again to push the screw part 14 to be processed.

[0037] A positioning component is arranged between the feeding channel 4 and the processing component 5. The positioning component is a groove structure. The positioning component is connected to the lifting component, and the lifting component is connected to the control component. When feeding is required, the control component controls the lifting component to rise, and the lifting component drives the positioning component to rise. The screw rod portion to be processed is carried on the positioning component, and the processing component is continuously fed in to ensure that the screw rod portion to be processed is always in a horizontal state, and the processing component is fed in at a determined height. After the screw rod portion to be processed is fed in, the control component controls the lifting component to descend, and then when another screw rod portion 14 to be processed needs to be fed in, the lifting component rises and controls the positioning component to rise.

[0038] The present invention also relates to a through-hole plug rod processing method with simple steps, which improves the degree of automation during the processing of the through-hole plug rod, reduces the time required for processing the through-hole plug rod thread, improves the processing efficiency, and reduces the labor intensity of workers. The through-hole plug rod processing method comprises the following steps:

[0039] S1. Place the blank to be processed on the feeding ramp 2, and the control component controls the connecting rod 11 to flip, and a blank to be processed leaves the feeding ramp 2 and falls into the feeding channel 4; S2. The control component controls the pushing component 5 to push the blank to be processed on the feeding channel to move toward the processing component 5; S3. The blank to be processed is fed between the first processing wheel 6 and the second processing wheel 7 of the processing component 5, and the control component controls the first processing wheel 6 and the second processing wheel 7 to rotate to complete the processing of the threaded structure on the surface of the blank to be processed; S4. The blank to be processed with the threaded structure processed leaves the first processing wheel 6 and the second processing wheel 7 to become the screw part 14 to be processed, and the screw part 14 to be processed falls into the receiving component 8; S5. Screw the nut 15 on the surface of the screw part 14 to be processed, and after the nut 15 is screwed into place, weld the nut 15 and the screw part 14 to be processed. S6. Process the chamfer 16 on one side of the nut 15 to complete the processing of the through-hole plug. Repeat steps S1-S6 to complete the processing of through-hole plug rods in batches.

[0040] The present invention also relates to a through-hole plug rod structure, comprising a screw portion 14 to be processed and a nut member 15, wherein the nut member 15 is screwed onto the surface of the screw portion 14 to be processed, the screw portion 14 to be processed and the nut member 15 are welded, and a chamfer 16 is provided on one side of the nut member 15. The above structure is simple in structure and convenient in processing, effectively meets the use requirements, and at the same time improves processing efficiency and reduces labor intensity.

[0041] The processing of the present invention is described below with specific embodiments:

[0042] After a 10-meter through-hole steel pipe is processed by a sawing machine, a 0.48-meter blank to be processed can be obtained. The outer diameter of the blank is 36mm, the upper deviation is +0.5mm, the lower deviation is +0.3mm, and the inner diameter is 15mm. After the processing parts are processed, the threaded structure is obtained, and the corresponding nut parts are rotated on the threaded structure, and then welded by a welding robot, and finally chamfered by a CNC lathe. The original production process is sawing, drilling, and lathing. Saw takes 0.1 hours, drilling takes 1.5 hours, and CNC lathing takes 1.65 hours, with a total working time of 3.25 hours; the improved process is now sawing, thread rolling, welding, and lathing. Saw takes 0.1 hours, CNC lathing takes 0.65 hours, welding takes 0.1 hours, and thread rolling takes 0.085 hours, with a total working time of 0.935 hours. The processing efficiency has been improved by 71.23%. Accordingly, while keeping the original processing time unchanged, 71.23% of human resources can be released. In addition, the original manufacturing process used 7.32kg of materials per product, while the new manufacturing process used 3.8kg of materials per product, saving 3.52kg of materials per product and increasing material utilization by 48.09%.

[0043] The beneficial effects of the structure, device and method of the present invention are: 1. The structure of the through-hole plug rod has been improved. The original structure was an integral type, but now it has been changed to a welded type. Due to the improvement in the structure, the automated operation of the threaded structure can be realized. The original manufacturing process used 7.32 kg of materials for each product, and the new manufacturing process used 3.8 kg of materials for each product, which saved 3.52 kg of materials per product and increased the material utilization rate by 48.09%. 2. A processing device for a threaded structure that can automatically feed and discharge materials is realized. The threaded structure processing procedure adds a feeding component, a discharging component, and a processing bearing channel. The threaded structure processing of the screw is replaced by a thread rolling process, which improves the degree of automation of the threaded structure processing, and optimizes the original screw production processes such as sawing, drilling, and turning to sawing, thread rolling, welding, and turning, so as to reduce the processing time of the screw, improve the processing efficiency, and reduce the labor intensity of workers.

A pushing component 5 is provided at one end of the feeding channel 4, and the other end of the feeding channel 4 is close to one end of the processing component 5. After the screw portion 14 to be processed falls into the feeding channel 4, the screw portion 14 to be processed is fed into the processing component for thread processing under the thrust of the pushing component 5. The processing component 5 is provided with a first processing wheel 6 and a second processing wheel 7. There is a gap between the first processing wheel 6 and the second processing wheel 7, which is convenient for the screw rod 14 to be processed to pass through. The first processing wheel 6 and the second processing wheel 7 are respectively connected to driving motors. Each driving motor drives a corresponding processing wheel to rotate, thereby controlling the screw rod to be processed to complete the thread processing in the process of passing through the first processing wheel 6 and the second processing wheel 7. After the processing is completed, the screw rod to be processed leaves the first processing wheel 6 and the second processing wheel 7. A receiving component 8 is provided at the other end of the processing component 5, and the screw rod to be processed that leaves the first processing wheel 6 and the second processing wheel 7 falls on the receiving component to complete the processing.
