[0023] Reference Figure 1 to Figure 10 , which is an embodiment of the present invention, provides a tapping machine for steel sleeve production, including a workbench 1, a loading platform 2 and a tapping mechanism 3, the loading platform 2 is used to convey the steel sleeve 001 to be processed to the workbench 1, the tapping mechanism 3 is used to process the steel sleeve 001 on the workbench 1, and also includes a placement plate 4, the placement plate 4 is intermittently rotated and arranged on the workbench 1, and the placement plate 4 is divided into a loading area 41, a tapping area 42, an observation area 43, a flushing and impurity removal area 44, a cleaning area 45 and a unloading area 46 in the circumferential direction; the lifting plate 5 is slidably arranged on the workbench 1 and is located on the side close to the flushing and impurity removal area 44 and the cleaning area 45; one end of the flushing pipe 7 is arranged on the lifting plate 5, and the other end is arranged in the flushing and impurity removal area 44. After the lifting plate 5 is lowered, the flushing pipe 7 enters the steel sleeve 001 located in the flushing and impurity removal area 44, and the flushing pipe 7 is used to clean the chips in the steel sleeve 001.

[0024] In the above scheme, the loading stage: the steel sleeve 001 to be processed is transported from the loading platform 2 to the loading area 41 of the placement plate 4, and the placement groove 401 on the placement plate 4 is used to fix the steel sleeve 001. Specifically, the steel sleeve 001 transported from the loading platform 2 can be installed in the placement groove 401 by manual placement. Tapping stage: the placement plate 4 rotates intermittently to send the steel sleeve 001 to the tapping area 42, and the tapping mechanism 3 performs tapping processing on the steel sleeve 001. Observation stage: after the tapping is completed, the placement plate 4 continues to rotate and sends the steel sleeve 001 to the observation area 43, where the staff can conduct a preliminary inspection of the tapping quality. Flushing and impurity removal stage: the placement plate 4 rotates to the flushing and impurity removal area 44, and the driving mechanism 6 drives the lifting plate 5 to descend, so that the flushing pipe 7 enters the interior of the steel sleeve 001, and sprays high-pressure water into the steel sleeve 001 through the flushing pipe 7 to flush out the internal chips. Cleaning stage: the placement plate 4 rotates to the cleaning area 45, and the lifting plate 5 descends again. At this time, the flushing pipe 7 has left, and the cleaning rod 8 enters the steel sleeve 001. The cleaning rod 8 can rotate or reciprocate to further clean the water stains and chips remaining in the steel sleeve 001. Unloading stage: the placement plate 4 rotates to the unloading area 46, and the lifting plate 5 drives the push rod 10 to move downward. Under the guidance of the inclined top surface, the push rod 11 on the push rod 10 pushes the steel sleeve 001 located in the unloading area 46 to the outside of the placement plate to complete the unloading.

[0025] The tapping machine realizes the assembly line operation of the steel sleeve 001 by setting different areas of the placement plate 4, thereby improving the production efficiency. At the same time, the flushing pipe 7 and the cleaning rod 8 are respectively set in the flushing and removing area 44 and the cleaning area 45, which can effectively remove the chips and water stains in the steel sleeve 001, reduce the subsequent cleaning process, and further improve the production efficiency.

[0026] Furthermore, it also includes a cleaning rod 8, one end of which is set on the lifting plate 5. After the lifting plate 5 is lowered, the other end of the cleaning rod 8 enters the steel sleeve 001 located in the cleaning area 45. The cleaning rod 8 is used to clean water stains and chips in the steel sleeve 001.

[0027] In the above scheme, when the placement plate 4 rotates to the cleaning area 45, the inside of the steel sleeve 001 has been washed by high-pressure water flow. Therefore, there will be more water flow or water stains remaining in the steel sleeve 001. A sponge column or a brush rod is provided on the working end of the lifting plate 5 to facilitate cleaning the inner wall of the steel sleeve 001. The lifting plate 5 descends, and the cleaning rod 8 enters the steel sleeve 001 located in the cleaning area 45. Driven by the lifting plate 5, the cleaning rod 8 can move up and down and rotate, and the brush head is in full contact with the inner wall of the steel sleeve 001 to clean the remaining water stains and chips. The setting of the cleaning rod 8 further improves the cleanliness of the steel sleeve 001, can effectively remove the water stains and chips that cannot be completely cleaned by the flushing pipe 7, ensures the quality of the steel sleeve 001, and reduces the residual impurities.

[0028] Furthermore, it also includes a top block 9, which is truncated cone-shaped and arranged in the middle of the placement plate 4, and has an inclined top surface; one end of the top rod 10 is arranged on the lifting plate 5, and the other end of the top rod 10 is located above the inclined top surface; the push rod 11 is slidably arranged on the end surface of the top rod 10, and the sliding direction of the push rod 11 is perpendicular to the axial direction of the top rod 10, and the bottom surface of the push rod 11 slides and abuts against the inclined top surface. After the lifting plate 5 drives the top rod 10 to move downward, the push rod 11 is used to push the steel sleeve 001 located in the unloading area 46 to the outside of the placement plate 4 under the guidance of the inclined top surface.

[0029] In the above scheme, the inclined top surface of the top block 9 is smooth and has a certain inclination angle. The bottom surface of the push rod 11 contacts the inclined top surface and is connected to the push rod 10 through a dovetail groove. When the placement plate 4 rotates to the unloading area 46, the lifting plate 5 drives the push rod 10 to move downward. As the push rod 10 moves downward, the push rod 11 slides along the end surface of the push rod 10 under the guidance of the inclined top surface, and the sliding direction of the push rod 11 is perpendicular to the axial direction of the push rod 10. The push rod 11 pushes the steel sleeve 001 located in the unloading area 46 to the outside of the placement plate to realize unloading. The unloading structure is simple, and the automatic unloading of the steel sleeve 001 can be realized by the movement of the lifting plate 5, which reduces manual operation and improves the degree of automation and production efficiency of production. Furthermore, the placement plate 4 has a plurality of placement grooves 401, which are respectively arranged in the loading area 41, the tapping area 42, the observation area 43, the flushing and removing debris area 44, the cleaning area 45 and the unloading area 46, and the placement grooves 401 are used to place the steel sleeve 001.

[0030] In the above scheme, the number of placement slots 401 in each area is set according to actual production needs. At each stage, the steel sleeve 001 is placed in the corresponding placement slot 401, and the placement slot 401 plays a role in positioning and fixing the steel sleeve 001, ensuring the stability of the steel sleeve 001 during the processing and avoiding processing errors caused by position offset. The setting of the placement slot 401 improves the accuracy and stability of the processing of the steel sleeve 001, enables each processing step to proceed smoothly, reduces the scrap rate, and improves product quality.

[0031] Furthermore, it also includes a limiting ring 12, which is provided in a plurality, and a limiting ring 12 is detachably provided in each placement groove 401, the limiting ring 12 has a shrinkage section 1201, and the shrinkage section 1201 is located in the placement groove 401, and the limiting ring 12 is used to clamp the steel sleeve 001 placed in the placement groove 401.

[0032] In the above scheme, when the steel sleeve 001 is placed in the placement groove 401, the limiting collar 12 is first installed in the placement groove 401, and then the steel sleeve 001 is installed on the limiting collar 12. The contraction section 1201 of the limiting collar 12 will automatically clamp the steel sleeve 001, further improving the fixing effect of the steel sleeve 001. When the steel sleeve 001 needs to be taken out, the limiting collar 12 can be removed by disassembling the clamp, or the top block 9 set under the placement plate 4 can be used to push the steel sleeve 001 out. The limiting collar 12 further enhances the fixing effect of the steel sleeve 001, prevents the steel sleeve 001 from shaking or displacement during processing, and ensures the processing quality.

[0033] Furthermore, it also includes a driving mechanism 6, which is arranged in the workbench 1, and the placement plate 4 and the lifting plate 5 are both transmission-connected to the driving mechanism 6, and the driving mechanism 6 is used to drive the placement plate 4 to rotate intermittently and simultaneously drive the lifting plate 5 to reciprocate; the driving mechanism includes a reduction motor 13, and the reduction motor 13 is arranged in the workbench 1; the intermittent transmission member 14 is rotatably arranged in the workbench 1, and the placement plate 4 is arranged on the intermittent transmission member 14; the first bevel gear 15 is arranged on the power output end on one side of the reduction motor 13; the second bevel gear 16 is arranged on the intermittent transmission member 14, and the first bevel gear 15 and the second bevel gear 16 are meshed; the disc 17 is arranged on the power output end on the other side of the reduction motor 13; one end of the connecting rod 18 is eccentrically arranged on the disc 17, and the other end is hinged to the lifting plate 5. After the disc 17 rotates, the connecting rod 18 drives the lifting plate 5 to reciprocate.

[0034] In the above scheme, after the reduction motor 13 is started, the meshing transmission of the first bevel gear 15 and the second bevel gear 16 drives the rotating disk 1401 to rotate, and the rotating disk 1401 drives the placement plate 4 to rotate intermittently. At the same time, the power output end on the other side of the reduction motor 13 drives the disc 17 to rotate. When the disc 17 rotates, the connecting rod 18 drives the lifting plate 5 to move back and forth, realizing the synchronous control of the intermittent rotation of the placement plate 4 and the reciprocating movement of the lifting plate 5. The driving mechanism 6 has a compact structure, and the synchronous drive of the placement plate 4 and the lifting plate 5 is realized through the reduction motor 13, which ensures the orderly progress of each processing process and improves the operation stability and reliability of the equipment.

[0035] Specifically, it should be made clear that the reducer has two power output ends, and the two power output ends are respectively located at the two ends of the same output shaft. After the reduction motor 13 is started, the reduction motor 13 will drive the intermittent transmission member 14 to work. The intermittent time of the intermittent transmission member 14 is the tapping time. According to different processing requirements, the processing time can be changed by adjusting the output speed of the reduction motor 13. Although the placement plate 4 rotates intermittently, the lifting plate 5 works continuously. Therefore, during the intermittent work of the placement plate 4, the lifting plate 5 can be lifted and lowered multiple times. It can be seen that the cleaning rod and the flushing pipe can be reciprocated in the steel sleeve 001 to perform cleaning work, thereby improving the cleaning and impurity removal efficiency.

[0036] Further, the tapping mechanism 3 includes a mechanical arm 19, which is arranged on the workbench 1; a mounting seat 20 is arranged on the mechanical arm 19, and the mounting seat 20 has a accommodating space; a driver 21 is arranged on the side wall of the mounting seat 20; a bevel gear disk 22 is arranged on the output end of the driver 21, and the bevel gear disk 22 is located in the accommodating space; a rotating shaft 23 is lifted, slid and rotated in the accommodating space, and both ends of the rotating shaft 23 pass through the accommodating space; a third bevel gear 24 is arranged on the rotating shaft 23, the third bevel gear 24 is located in the accommodating space, and the third bevel gear 24 is meshed with the bevel gear disk 22; a fourth bevel gear 25 is arranged on the rotating shaft 23, the fourth bevel gear 25 is located in the accommodating space, and the fourth bevel gear 25 is meshed with the bevel gear disk 22; a tapping drill rod 26 is detachably arranged on the rotating shaft 23, and when the tapping drill rod 26 taps, the fourth bevel gear 25 is meshed with the bevel gear disk 22, and when the tapping drill rod 26 retracts, the third bevel gear 24 is meshed with the bevel gear disk 22.

[0037] In the above scheme, when the steel sleeve 001 is sent to the tapping area 42, the mechanical arm 19 moves the mounting seat 20 to a suitable position so that the tapping drill rod 26 is aligned with the steel sleeve 001. When the tapping drill rod 26 is against the position of the steel tower to be processed, the steel sleeve 001 will exert an upward pressure on the tapping drill rod 26. Under the action of the pressure, the bevel gear plate 22 and the fourth bevel gear 25 are meshed, and the spring 31 is in a compressed state. Then the driver 21 is started, driving the bevel gear plate 22 to rotate, the bevel gear plate 22 drives the fourth bevel gear 25 to rotate, the fourth bevel gear 25 drives the rotating shaft 23 to rotate, and the tapping drill rod 26 starts to tap the steel sleeve 001. After the tapping is completed, the mechanical arm 19 moves up, and the spring 31 is in a released state. At this time, the driver 21 still maintains the same direction and speed rotation as during tapping. Under the action of the spring 31 and the steel sleeve 001 with internal threads, the shaft 23 moves down, and the bevel gear plate 22 is meshed with the third bevel gear 24. At this time, the tapping drill rod 26 will reverse and retreat. The tapping mechanism 3 can realize the forward and reverse rotation of the tapping drill rod 26 through the transmission of the bevel gear without changing the speed and direction of the driver 21, and the tapping mechanism 3 is completed by the lifting movement of the mechanical arm 19. Not only is the structure simple, but the transmission is reliable, which can meet the requirements of rapid processing of the steel sleeve 001 tapping and improve the efficiency of tapping.

[0038] Furthermore, it also includes a limiting cylinder 27, which is arranged in the accommodating space and sleeved on the rotating shaft 23. After the drill rod is lifted and slid, the limiting cylinder 27 limits the third bevel gear 24 or the fourth bevel gear 25.

[0039] In the above scheme, when the tapping drill rod 26 is lifted and slid, when the third bevel gear 24 or the fourth bevel gear 25 is meshed with the bevel gear plate 22, the limiting cylinder 27 limits the third bevel gear 24 or the fourth bevel gear 25 to prevent lateral displacement during rotation, thereby ensuring the stability and accuracy of the transmission. At the same time, the limiting cylinder 27 can also limit the maximum stroke of the third bevel gear 24 and the fourth bevel gear 25, ensuring that the third bevel gear 24 and the fourth bevel gear 25 can be quickly and accurately meshed with the bevel gear plate 22 for transmission. The setting of the limiting cylinder 27 improves the transmission stability of the tapping mechanism 3, avoids transmission failures caused by displacement, prolongs the service life of the equipment, and ensures the tapping quality.

[0040] Furthermore, it also includes a guide column 28, which has a plurality of guide columns 28, and the plurality of guide columns 28 are all arranged at the corners of the top surface of the mounting seat 20; a sliding plate 29 is slidably arranged on the guide column 28, and one end of the rotating shaft 23 away from the tapping drill rod 26 is arranged on the sliding plate 29; a top plate 30 is arranged on the top of the guide column 28; one end of a spring 31 is arranged on the top plate 30, and the other end is arranged on the sliding plate 29, and the spring 31 is used to provide a force for the rotating shaft 23 to move downward.

[0041] In the above scheme, the guide column 28 is a cylindrical rod body, and there are four of them, which are respectively arranged at the four corners of the top surface of the mounting seat 20. During the tapping process, when the tapping drill rod 26 contacts the steel sleeve 001, the spring 31 is compressed, providing a downward force for the rotating shaft 23, so that the tapping drill rod 26 can better contact the steel sleeve 001, thereby ensuring the tapping effect. After the tapping is completed, the spring 31 restores its elasticity, drives the rotating shaft 23 to move upward, and makes the tapping drill rod 26 retreat. The setting of the spring 31 and the guide column 28 provides stable support and elastic force for the rotating shaft 23, ensures the stability and accuracy of the tapping drill rod 26 during the tapping and retreat process, and improves the tapping quality and efficiency.

[0042] Furthermore, the intermittent transmission member 14 includes a rotating disk 1401, which is arranged on the second bevel gear 16; the column 1402 is arranged on the rotating disk 1401 and is located on one side of the center of the rotating disk 1401; the driven disk 1403 is arranged at the bottom of the placement plate 4, and the driven disk 1403 has a slot 1404, and the loading area 41, the tapping area 42, the observation area 43, the flushing and de-impurity area 44, the cleaning area 45 and the unloading area 46 respectively correspond to a slot 1404. After the rotating disk 1401 rotates, the column 1402 first slides into and then slides out of the slot 1404.

[0043] In the above scheme, the driven disk 1403 is provided with a plurality of slots 1404, and the shape of the slots 1404 matches the column 1402. The reduction motor 13 drives the rotating disk 1401 to rotate through the first bevel gear 15 and the second bevel gear 16. When the rotating disk 1401 rotates, the column 1402 first slides into the corresponding slot 1404 on the driven disk 1403, driving the placement plate 4 to rotate a certain angle, and then the column 1402 slides out of the slot 1404, and the placement plate 4 stops rotating. In this way, the intermittent rotation of the placement plate 4 is achieved, so that the steel sleeve 001 passes through each processing area in turn. The intermittent transmission member 14 has a simple structure. Through the cooperation of the column 1402 and the slot 1404, the precise intermittent rotation of the placement plate 4 is achieved, which ensures the orderly progress of each processing procedure and improves the automation degree and production efficiency of the equipment.
