Description

Technical Field

[0001] The invention belongs to the technical field of steel pipe processing, and in particular relates to a steel pipe drilling device with an iron filings collecting function. Background Art

[0002] Steel pipe is a kind of metal component commonly used in mechanical equipment and people's lives. To process steel pipe into the required components, it is necessary to perform various operations such as cutting, drilling, and welding on the steel pipe. A drilling machine refers to a mechanical device that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. The desired effect can be achieved by drilling holes in precision parts.

[0003] Existing drilling machines for drilling holes on the surface of steel pipes are usually manually handheld drilling machines, which have low production efficiency and high labor intensity. In addition, when drilling holes in the steel pipe, when drilling holes in different positions of the steel pipe, it is necessary to manually adjust the position of the steel pipe, which is inconvenient to operate and inefficient. At the same time, when drilling, iron filings will remain inside the steel pipe, which is inconvenient to clean. Summary of the invention

[0004] The purpose of the present invention is to solve the problem of difficult positioning in the existing technology, and to propose a steel pipe drilling device with an iron chip collection function.

[0006] Furthermore, the positioning device includes a fixed rotating sleeve fixed on the left side of the stepped hollow shaft, a positioning motor fixed on the upper side of the fixed rotating sleeve, a power shaft fixed at the output end of the positioning motor, a power gear fixed at the left end of the power shaft, a driven gear fixed on the left side of the retractable inner rotating shaft, and the driven gear meshes with the power gear.

[0007] Furthermore, the outer side of the fixed rotating sleeve is square, and there is a certain gap between the fixed rotating sleeve and the shell.

[0008] Furthermore, a positioning plate is fixedly provided on the left side wall of the shell, an electric-controlled telescopic rod is fixedly provided on the rear side of the positioning plate, the front side of the electric-controlled telescopic rod is a telescopic end, the telescopic end of the electric-controlled telescopic rod is provided with a tooth plate, an adjusting gear is fixedly provided on the left end of the stepped hollow shaft, the lower side of the adjusting gear is meshed with the tooth plate, a fixed support rod is fixedly provided on the left side wall of the shell, a limit swivel is rotatably provided on the fixed support rod, and the upper side of the limit swivel is in conflict with the tooth plate.

[0009] Furthermore, a support plate is fixedly provided on the rear side of the upper end of the shell, a motor bracket is fixedly provided on the left side wall of the support plate, a servo motor is fixedly provided in the motor bracket, a threaded shaft is provided at the output end of the servo motor, a movable sleeve is threadedly engaged with the threaded shaft, a slide rail is provided on the upper side of the support plate, a slide plate is slidably provided on the slide rail, and the rear side of the slide plate is fixedly connected to the movable sleeve.

[0010] Furthermore, a cylinder is fixedly provided in the middle part of the upper side of the skateboard, a fixing plate is fixedly provided at the upper end of the cylinder, a drilling motor is fixedly provided at the lower side of the front end of the fixing plate, a drilling shaft is provided at the output end of the drilling motor, a drill seat is provided at the lower end of the drilling shaft, a drill bit is provided at the lower side of the drill seat, and a processing table is fixedly provided on the left and right side walls of the shell, and the processing table is located at the lower side of the positioning device.

[0011] Furthermore, the axis of the drill bit and the axis of the retractable inner rotating shaft are located in the same plane and are perpendicular to each other, and the upper side of the processing table is an arc surface for placing the steel pipe.

[0012] Furthermore, a negative pressure pump is fixedly provided on the upper side of the lower side wall of the shell, a negative pressure pipe is provided at the output end of the negative pressure pump, a collecting box is fixedly provided on the upper side of the lower side wall of the shell, the collecting box is located on the left side of the negative pressure pump, the left side of the negative pressure pipe is connected with the collecting box, a U-shaped straw is provided at the left end of the collecting box, the upper side of the U-shaped straw extends into the retractable inner rotating shaft, an air suction hood is fixedly provided on the upper right end of the U-shaped straw, and a support frame is fixedly provided on the lower side of the shell.

[0013] The steel pipe to be processed is fed in from the right side of the equipment, and the left side of the steel pipe is gradually fed to the outside of the positioning splint, the positioning motor is started to rotate, and the output end of the positioning motor drives the power shaft to rotate. When the power shaft rotates, it drives the power gear to rotate, so that the driven gear meshes with the power gear and rotates, and the driven gear drives the retractable inner shaft to rotate inside the stepped hollow shaft. At this time, since the electric control telescopic rod does not work, the gear plate does not rotate, so the stepped hollow shaft is stuck and does not rotate under the action of the adjusting gear, so that the fixed hinge sleeve is immobile at this time. Therefore, when the retractable inner shaft rotates, it drives the threaded hinge sleeve at the right thread to move to the left. When the threaded hinge sleeve moves to the left, the active connecting rod and the driven connecting rod are mutually hinged to support the corresponding positioning splint to the outside, and gradually conflict with the inner wall of the steel pipe, thereby realizing the fixed positioning of the steel pipe. The positioning motor is turned off and stops rotating, and the servo motor and the drilling motor are started to work. Under the forward and reverse rotation of the servo motor, the slide plate is driven to move left and right on the slide rail through the threaded shaft and the movable sleeve to realize the left and right movement of the steel pipe drilling position. At the same time, the output end of the drilling motor drives the power shaft to rotate, and the drilling shaft drives the drill bit to rotate through the drill bit seat. After aligning the drilling position, the cylinder is controlled to contract, driving the fixed plate to descend, thereby driving the lower drill bit to drill the steel pipe. At the same time, the negative pressure pump generates negative pressure, which acts on the suction hood through the negative pressure pipe, the collection box and the U-shaped suction pipe to absorb the iron filings generated inside the steel pipe, and enter the collection box through the U-shaped suction pipe to realize the collection of iron filings. The positioning device supports the inner wall of the steel pipe to achieve stable fixed positioning of the steel pipe, ensuring the stability of the steel pipe during processing. At the same time, the negative pressure of the collecting device generates suction, and under the action of the U-shaped suction pipe, suction is generated from the inside of the positioning device to realize the collection and cleaning of iron filings inside the steel pipe.

[0014] When it is necessary to adjust the drilling position in the circumferential direction of the steel pipe, the electrically controlled telescopic rod is controlled to shrink, driving the toothed plate to move in the front-rear direction, so that the adjusting gear meshes and rotates with the toothed plate, and the adjusting gear drives the stepped hollow shaft to rotate synchronously when rotating, and the stepped hollow shaft drives the positioning motor to rotate synchronously through the fixed rotating sleeve when rotating. Since the positioning motor does not work at this time, the power shaft does not rotate, and thus the power gear does not rotate, so that when the power gear rotates with the stepped hollow shaft as the axis, it drives the retractable inner rotating shaft to rotate synchronously through the driven gear, that is, the retractable inner rotating shaft and the stepped hollow shaft have no relative rotation at this time, thereby avoiding loosening of the steel pipe when adjusting the angle, and the stepped hollow shaft drives the steel pipe to rotate through the fixed hinge sleeve, the driven connecting rod, and the positioning clamp to adjust the angle. Under the design of the adjusting device, the steel pipe does not need to be repositioned, and holes can be drilled at different positions of the steel pipe, thereby improving the drilling efficiency and facilitating the operation.

[0026] like Figure 1 , Figure 2 As shown, a support plate 11 is fixedly provided on the rear side of the upper end of the shell 10, a motor bracket 13 is fixedly provided on the left side wall of the support plate 11, a servo motor 14 is fixedly provided in the motor bracket 13, a threaded shaft 15 is provided at the output end of the servo motor 14, a movable sleeve 16 is threadedly engaged with the threaded shaft 15, a slide rail 12 is provided on the upper side of the support plate 11, a slide plate 17 is slidably provided on the slide rail 12, and the rear side of the slide plate 17 is fixedly connected to the movable sleeve 16.

[0027] like Figure 1 As shown, a cylinder 18 is fixedly provided at the middle part of the upper side of the slide plate 17, a fixing plate 19 is fixedly provided at the upper end of the cylinder 18, a drilling motor 20 is fixedly provided at the lower side of the front end of the fixing plate 19, a drilling shaft 21 is provided at the output end of the drilling motor 20, a drill seat 22 is provided at the lower end of the drilling shaft 21, a drill bit 23 is provided at the lower side of the drill seat 22, and a processing table 42 is fixedly provided at the left and right side walls of the shell 10, and the processing table 42 is located at the lower side of the positioning device.

[0028] like Figure 1 As shown, the axis of the drill bit 23 and the axis of the retractable inner rotating shaft 33 are located in the same plane and are perpendicular to each other. The upper side of the processing table 42 is an arc surface for placing the steel pipe.

[0029] like Figure 1 , Figure 5As shown, a negative pressure pump 44 is fixedly provided on the upper side of the lower side wall of the shell 10, and a negative pressure pipe 45 is provided at the output end of the negative pressure pump 44. A collecting box 43 is fixedly provided on the upper side of the lower side wall of the shell 10, and the collecting box 43 is located on the left side of the negative pressure pump 44. The left side of the negative pressure pipe 45 is connected with the collecting box 43, and a U-shaped suction pipe 35 is provided at the left end of the collecting box 43. The upper side of the U-shaped suction pipe 35 extends into the retractable inner rotating shaft 33, and an air suction hood 36 is fixedly provided at the upper right end of the U-shaped suction pipe 35. A support frame 46 is fixedly provided on the lower side of the shell 10.

[0030] The steel pipe to be processed is fed in from the right side of the equipment, and the left side of the steel pipe is gradually fed to the outside of the positioning clamping plate 41, and the positioning motor 30 is started to rotate. The output end of the positioning motor 30 drives the power shaft 31 to rotate, and the power shaft 31 drives the power gear 32 to rotate when rotating, so that the driven gear 34 meshes with the power gear 32 and rotates, and the driven gear 34 drives the retractable inner rotating shaft 33 to rotate inside the stepped hollow shaft 27. At this time, since the electric control telescopic rod 25 does not work, the tooth plate 26 does not rotate, so that the stepped hollow shaft 27 is not rotated. 7 is stuck and does not rotate under the action of the adjusting gear 28, that is, the fixed hinge sleeve 38 does not move at this time, so when the retractable inner rotating shaft 33 rotates, it drives the threaded hinge sleeve 37 at the right thread to move to the left. When the threaded hinge sleeve 37 moves to the left, the active connecting rod 40 and the driven connecting rod 39 are mutually hinged to support the corresponding positioning clamping plate 41 outward, and gradually conflict with the inner wall of the steel pipe, thereby achieving the fixed positioning of the steel pipe. The positioning motor 30 is turned off and stops rotating, and the servo motor 14 and the drilling motor 20 are started to move. The servo motor 14 rotates forward and backward, and the slide plate 17 is driven to move left and right on the slide rail 12 through the threaded shaft 15 and the movable sleeve 16 to realize the left and right movement of the steel pipe drilling position. At the same time, the output end of the drilling motor 20 drives the power shaft 31 to rotate, and the drilling shaft 21 drives the drill bit 23 to rotate through the drill seat 22. After aligning the drilling position, the cylinder 18 is controlled to shrink, and the fixed plate 19 is driven to descend, thereby driving the lower drill bit 23 to drill the steel pipe. At the same time, the negative pressure pump 44 generates negative pressure, and the negative pressure pipe 44 generates negative pressure. 45. The collecting box 43 and the U-shaped suction pipe 35 act on the suction hood 36 to absorb the iron filings generated inside the steel pipe, and the iron filings enter the collecting box 43 through the U-shaped suction pipe 35 to collect the iron filings. The positioning device supports the inner wall of the steel pipe to achieve stable fixed positioning of the steel pipe, thereby ensuring the stability of the steel pipe during processing. At the same time, the negative pressure of the collecting device generates suction, and under the action of the U-shaped suction pipe 35, suction is generated from the inside of the positioning device to collect and clean the iron filings inside the steel pipe.

[0031] When the drilling position in the circumferential direction of the steel pipe needs to be adjusted, the electrically controlled telescopic rod 25 is controlled to be retracted, driving the toothed plate 26 to move in the front-rear direction, so that the adjusting gear 28 is meshed with the toothed plate 26 and rotates, and the adjusting gear 28 drives the stepped hollow shaft 27 to rotate synchronously when rotating, and the stepped hollow shaft 27 drives the positioning motor 30 to rotate synchronously through the fixed rotating sleeve 29 when rotating. Since the positioning motor 30 does not work at this time, the power shaft 31 does not rotate, and the power gear 32 does not rotate, so the power gear 32 is rotated at When the stepped hollow shaft 27 is an axis, the driven gear 34 drives the retractable inner rotating shaft 33 to rotate synchronously, that is, the retractable inner rotating shaft 33 and the stepped hollow shaft 27 have no relative rotation at this time, thereby avoiding the loosening of the steel pipe when adjusting the angle. The stepped hollow shaft 27 drives the steel pipe to rotate through the fixed hinge sleeve 38, the driven connecting rod 39, and the positioning clamping plate 41 to adjust the angle. Under the design of the adjusting device, the steel pipe does not need to be repositioned, and holes can be drilled at different positions of the steel pipe, thereby improving the drilling efficiency and facilitating the operation.

[0032] Compared with the prior art, the steel pipe drilling equipment with iron chips collection function has the following advantages:

[0033] 1. The positioning device supports the inner wall of the steel pipe to achieve stable and fixed positioning of the steel pipe, ensuring the stability of the steel pipe during processing.

[0034] 2. Suction is generated through negative pressure. Under the action of the U-shaped straw, suction is generated inside to collect and clean the iron filings inside the steel pipe.

[0035] 3. The steel pipe can be drilled at different positions without repositioning it, which improves the drilling efficiency and is easy to operate.

[0036] The above descriptions are merely embodiments of the present invention, and are not intended to limit the patent protection scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
