In building, bridge, petroleum, natural gas and other engineering, steel pipes usually need to be punched for connection, fixation or drainage.

[0003] When punching the steel pipe, a punching device needs to be used. At present, the punching device on the market usually drives the drill bit to rotate by the motor to punch the steel pipe. However, the drill bit will inevitably be worn and skewed during long-term use.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0042] In order to solve the technical problem that the existing punching device is worn and skewed after long-term use, and then deviation occurs during punching, thereby affecting the punching precision, as shown in Figures 1-8 The following preferred technical solutions are provided:

[0043] The steel pipe rapid positioning and punching device comprises a machining table 1 and a deviation rectifying mechanism 8. The side wall of the machining table 1 is fixedly provided with a control console 101. The model of the control console 101 is SET-K022. The control console 101 is provided with knobs, switches, display screens and the like. The control console 101 is used for controlling the starting, stopping, speed adjustment, punching depth setting and the like of the punching device. The working state, parameter setting, fault information and the like are displayed on the display screen, so as to facilitate the better control of the auxiliary workers. The control console 101 is fixedly provided with an alarm 102. The model of the alarm 102 is Q183-4. The alarm 102 can timely send alarm sound or flashing light to remind the operator to pay attention to the fault, so as to quickly take corresponding measures to avoid causing greater loss or safety accident. The alarm 102 is connected with the control console 101 on the control console 101. When an abnormal signal is detected, the control console 101 triggers the alarm 102 to work. The machining table 1 is provided with a clamping mechanism 2. The clamping mechanism 2 is provided with a steel pipe body 3 clamped and fixed thereon. The clamping mechanism 2 facilitates the clamping and fixing of the steel pipe body 3.

[0044] It should be noted that the clamping mechanism 2 is composed of a clamping seat, a hydraulic cylinder, an electric push rod and a clamping ring. During clamping of the steel pipe, the steel pipe is placed on the clamping seat. The clamping ring is driven to move by the extension and retraction of the electric push rod, so as to clamp and fix the two sides of the steel pipe. After the steel pipe is clamped firmly, the hydraulic cylinder is started to drive the piston to move by the hydraulic power generated by the hydraulic cylinder, so as to drive the clamped steel pipe to slide, so as to realize stable clamping and continuous conveying of the steel pipe. Since the technical scheme belongs to the prior art in the art and is not the main innovation, only contains and is not unique, the detailed description is omitted.

[0045] The machining table 1 is provided with a mounting rod 4 fixedly arranged on the top surface. The mounting rod 4 is sleeved with a spring 5. The spring 5 provides certain buffer and elastic support for a mounting frame 6. The mounting rod 4 is slidably sleeved with the mounting frame 6. The two ends of the spring 5 are fixedly connected with the bottom surface of the mounting frame 6 and the top surface of the machining table 1. The driving machine 71 is electrically connected with the machining table 1. The mounting frame 6 is provided with a punching mechanism 7. The punching mechanism 7 can be flexibly lifted according to the needs during work. The buffer effect of the spring 5 can reduce the impact force generated during punching on the device. The punching mechanism 7 facilitates the punching of the steel pipe body 3. The punching mechanism 7 comprises a driving machine 71. The driving machine 71 is fixedly arranged on the top surface of the mounting frame 6. The output end of the driving machine 71 is fixedly connected with a shaft coupling 72. The output end of the shaft coupling 72 is fixedly connected with a drill bit 73. The machining table 1 is rotatably connected with two lead screws 62. The lead screws 62 are symmetrically arranged. The bottom surface of the machining table 1 is fixedly connected with a first motor 61. The output end of the first motor 61 is fixedly connected with the lead screws 62.

[0046] Specifically, when the steel pipe body 3 is placed between the clamping jaws of the clamping mechanism 2, the clamping mechanism 2 is started by operating the button on the operation console 101, the clamping jaws are gradually tightened to firmly clamp the steel pipe body 3, the first motor 61 is started to drive the screw rod 62 to rotate, when the screw rod 62 rotates, the mounting frame 6 on the outer portion thereof is screwed and immediately slides downward under the action of the screw, when the mounting frame 6 slides downward, the spring 5 is deformed by abutting against the mounting frame 6, at the same time, the drill bit 73 mounted at the lower end of the mounting frame 6 immediately descends and gradually approaches and contacts the steel pipe body 3, the driving machine 71 is started, the driving machine 71 drives the coupling 72 to rotate the drill bit 73, and the punching operation is started.

[0047] The side wall of the mounting frame 6 is rotationally connected with a screw rod 91, an L-shaped sliding seat 92 is threadedly sleeved on the screw rod 91, the L-shaped sliding seat 92 can be moved along the axial direction of the screw rod 91 by rotating the screw rod 91, the L-shaped sliding seat 92 is fixedly connected with a fixing rod 93, the fixing rod 93 is slidably sleeved with a sliding rod 94, the sliding rod 94 can freely slide on the fixing rod 93, so that the limiting column 11 does not interfere with the movement in the subsequent punching process, the bottom surface of the sliding rod 94 is fixedly connected with the connecting rod 10, and the bottom surface of the connecting rod 10 is fixedly connected with the limiting column 11.

[0048] The deviation rectifying mechanism 8 comprises a cylinder 81 fixed on the bottom surface of the mounting frame 6, which can output corresponding thrust or pull force according to control instructions through the control console 101, thereby controlling the lifting movement of the abutting plate 87. The output end of the cylinder 81 is fixedly connected with a connecting block 82, which plays a role in transmitting the power of the cylinder 81. A sliding groove 83 is formed on the bottom surface of the connecting block 82. A threaded rod 84 is rotatably connected to the side wall of the connecting block 82. A sliding column 85 is threadedly connected to the threaded rod 84. A limiting rod 86 is fixedly connected to the top surface of the sliding column 85. The limiting rod 86 is slidably connected with the sliding groove 83, thereby providing a guide track for the sliding movement of the sliding column 85, ensuring that the sliding column 85 can maintain a stable direction during movement. The bottom surface of the sliding column 85 is fixedly connected with the abutting plate 87. Through the movement of the sliding column 85, the abutting plate 87 can be driven to move close to the drill bit 73 for testing, thereby avoiding the use of a severely worn drill bit 73 to cause errors in punching accuracy. A vibration sensor 88 is fixedly installed on the side wall of the abutting plate 87. The vibration sensor 88 is electrically connected with the alarm 102. The vibration sensor 88 is used for real-time monitoring of the wear displacement of the drill bit 73. The drill bit 73 will be skewed and worn due to the resistance force during long-term use. When the abutting plate 87 moves to within the error range of the rotating and polishing of the drill bit 73, the drill bit 73 will not contact the abutting plate 87. When the skew is serious, the abutting plate 87 will be contacted during the rotating process, thereby generating vibration. The vibration sensor 88 can convert the detected vibration signal into an electric signal and transmit it to the alarm 102. When the detected vibration signal exceeds the preset threshold value, it indicates that a punching deviation may occur. The vibration sensor 88 can send a signal to the alarm 102 in time to trigger an alarm so that the staff can make timely maintenance and replacement, thereby reducing costs in time.

[0049] Specifically, the cylinder 81 is started to drive the abutting plate 87 to descend outside the drill bit 73. Then the threaded rod 84 is manually rotated. When the threaded rod 84 rotates, the sliding column 85 threadedly matched therewith will move horizontally along the axis through the thread action. When moving, the limiting rod 86 on the top of the sliding column 85 will immediately slide horizontally along the sliding groove 83. At the same time, the abutting plate 87 at the bottom will immediately move to within the preset threshold range according to the drill bit 73 of different sizes. Then the driving machine 71 is started to drive the coupling 72 to rotate the drill bit 73. When the drill bit 73 is skewed within the error range, it will not cause too much accuracy error. At this time, the drill bit 73 will not contact the abutting plate 87 during rotation. When the drill bit 73 is skewed beyond the error range, the drill bit 73 will contact the abutting plate 87 during rotation, thereby generating vibration. The vibration sensor 88 can detect this change in real time and convert the vibration signal into an electric signal to transmit to the alarm 102. After receiving the abnormal signal, the alarm 102 will issue an alarm and transmit the signal to the control console 101. The control console 101 can judge the direction and degree of deviation according to the received signal, drive the cylinder 81 to reset, and stop driving the driving machine 71 according to the corresponding control instructions, so as to facilitate the staff to overhaul or replace it.

[0050] In order to solve the technical problem that the interval cannot be adjusted according to the requirement in the process of drilling holes on the steel pipe, such as Figures 4-6 As shown in the figure, the following preferred technical solutions are provided:

[0051] The steel pipe rapid positioning and drilling device comprises a positioning mechanism 9, which is convenient for guiding and positioning when continuously drilling the steel pipe body 3. The positioning mechanism 9 comprises an adjusting part, which is convenient for adjusting the interval when drilling the holes. The adjusting part comprises a fixed plate 921, which provides support. The fixed plate 921 is fixedly connected to the bottom surface of the mounting frame 6. The side wall of the fixed plate 921 is fixedly provided with a second motor 922. The output end of the second motor 922 is fixedly connected with a screw rod 91. Through the rotation of the screw rod 91, the components connected therewith can be moved in a straight line direction, so as to realize the adjustment of the drilling position.

[0052] Specifically, when it is required to drill holes on the steel pipe body 3, the operator first determines the interval between the holes according to the design requirement, and then inputs the instruction through the related button on the operation console 101 or inputs the instruction, and sends a control signal to the second motor 922. After receiving the control signal, the second motor 922 starts to operate according to the preset parameters. The rotation of the motor is transmitted to the screw rod 91 through the output shaft, so that the screw rod 91 rotates. The sliding block matched with the screw rod 91 will move linearly along the axial direction of the screw rod 91 under the driving of the screw rod 91. A series of components at the bottom will also move, so that the drilling position of the drill bit 73 can be adjusted during the drilling process, thereby meeting the drilling requirement of different interval holes.

[0053] In order to solve the technical problem that the interval cannot be adjusted according to the requirement in the process of drilling holes on the steel pipe, such as Figures 4-6 As shown in the figure, the following preferred technical solutions are provided:

[0054] The positioning mechanism 9 comprises a rotating part facilitating rotational adjustment of the support according to the position of the special-shaped aperture, and the rotating part comprises a third motor 95 fixed on the side wall of the fixed plate 921, and a rotating rod 96 fixedly connected to the output end of the third motor 95 and capable of rotating flexibly with the mounting frame 6 as a support point under the driving of the third motor 95. The rotating rod 96 is rotationally connected to the mounting frame 6, and clamping strips 97 are fixedly connected to the side walls on both sides of the rotating rod 96. The lower half of the L-shaped sliding seat 92 is hollow, and a worm 98 is rotationally connected in the L-shaped sliding seat 92. Sliding grooves 83 are formed in the two sides of the worm 98, facilitating the horizontal sliding of the clamping strips 97. The clamping strips 97 are used in cooperation with the sliding grooves 83 in the L-shaped sliding seat 92 to realize the relative sliding and connection between the rotating rod 96 and the L-shaped sliding seat 92. A turntable 910 is rotationally connected to the bottom wall of the L-shaped sliding seat 92. The clamping strips 97 on the rotating rod 96 can make the worm 98 and the L-shaped sliding seat 92 slide in the sliding grooves 83, and can drive the worm 98 to rotate in the L-shaped sliding seat 92. The bottom wall of the L-shaped sliding seat 92 is rotationally connected to the turntable 910, which provides support and rotation space for the rotation of the turntable 910. The top surface of the turntable 910 is connected to a worm wheel 99, and the worm wheel 99 is in meshing connection with the worm 98. The inside of the worm wheel 99 is hollow. The clamping strips 97 on the rotating rod 96 can slide in the sliding grooves 83, thereby driving the worm 98 to rotate. At the same time, the bottom wall of the L-shaped sliding seat 92 is rotationally connected to the turntable 910, which provides support and rotation space for the rotation of the turntable 910. The L-shaped sliding seat 92 plays a key role in connecting and transmitting power in the entire rotating part, converts the rotation of the rotating rod 96 into the rotation of the worm 98, and provides conditions for the subsequent rotation of the worm wheel 99.

[0055] A fixed rod 93 is arranged in the hollow of the worm wheel 99, a sliding rod 94 is coaxially fixedly installed on the top surface of the sleeve 912, a sleeve 912 is fixedly connected to the top surface of the sleeve 912, and a telescopic rod 911 is fixedly connected to the bottom surface of the turntable 910. This arrangement enables the sliding rod 94 to rotate with the turntable 910, and through the telescopic action of the telescopic rod 911, the position and height of the sliding rod 94 can be adjusted to a certain extent. The fixed rod 93 provides support and guidance for the sliding rod 94.

[0056] Specifically, when it is necessary to punch the special-shaped hole on the steel pipe body 3, the operator first inputs the position information of the special-shaped hole through the control console 101. After receiving the information, the control console 101 issues an instruction to the third motor 95, and the third motor 95 starts according to the instruction and outputs corresponding power to drive the rotating rod 96 to rotate. The clamping strip 97 on the rotating rod 96 rotates with the rotating rod 96, thereby driving the worm 98 to rotate in the L-shaped sliding seat 92. The rotation of the worm 98 transmits power to the worm gear 99, so that the worm gear 99 rotates, and in turn drives the rotating table 910 at the bottom to rotate, and the fixed rod 93, the sliding rod 94, the limiting column 11 and other components at the bottom synchronously rotate, so that when the limiting column 11 at the bottom supports and positions, it can accurately and stably support and guide the position of the special-shaped hole on the steel pipe body 3, and ensure the accuracy and quality of the punching.

[0057] In order to solve the technical problem that the hole diameter cannot be adjusted during punching of the steel pipe, Figures 7-8 as shown in the description, the following preferred technical solutions are provided:

The hole supporting plate 12 can adjust its position and angle according to the position change of the sleeve 116 through driving of the connecting rods 119 and the support blocks 121, thereby forming a "hole-like" structure with adjustable size, which is used for positioning and guiding the row punching and punching type to adapt to punching requirements of different hole diameters.

[0059] The telescopic columns 122 are symmetrically arranged in two about the support columns 113, the notches 111, the telescopic columns 122 and the hole supporting plate 12 are provided in plurality and arranged in a circumferential array. The telescopic action of the telescopic columns 122 can assist movement and adjustment of the hole supporting plate 12, thereby enhancing stability of the hole supporting plate 12 and flexibility of adjustment. When the hole supporting plate 12 needs to adjust position or angle, the telescopic columns 122 will be telescoped according to actual conditions, so that the hole supporting plate 12 can accurately reach a predetermined position.

[0060] Specifically, when the hole diameter of the required punching increases, the worker replaces the different drill bit 73 to perform the punching operation, when the drill bit 73 is replaced, the hole diameter will change when the punching is performed, the worker inputs the hole diameter parameter through the control console 101, the control console 101 receives the parameter and analyzes and processes it, and sends corresponding instructions to the fourth motor 114, the fourth motor 114 starts according to the instructions, and drives the stud 115 to rotate. The rotation of the stud 115 makes the sleeve 116 move along the axial direction of the stud 115, with the movement of the sleeve 116, the support block 118 fixed on the outer wall of the sleeve 116 will also move, the movement of the block is transmitted to the support block 121 through the articulated connecting rod 119, and then drives the hole supporting plate 12 to move, at the same time, the telescopic column 122 will perform corresponding telescopic action according to the movement of the hole supporting plate 12, so as to maintain the stable and accurate position of the hole supporting plate 12, through the joint action of the plurality of hole supporting plates 12 distributed in the circumferential array, the size of the "hole" formed by the hole supporting plate 12 is changed, so as to match the hole diameter required for punching, so that when the punching is performed, the limiting column 11 will be correspondingly lowered and clamped into the hole diameter which has been punched to support, so that the axial state can be maintained during the subsequent punching process without deviation, and the punching precision is improved.
