Description

Technical Field

[0001] This application relates to the technical field of drilling equipment, and particularly to an inclined hole machining device. Background Art

[0002] The machining of inclined holes in tubular components (such as steel pipes, hereinafter referred to as pipe fittings) is a common requirement in industrial manufacturing, and it is mainly applied to scenarios such as pipe connection, fluid transmission, or structural support. The design of inclined holes can optimize the assembly angle between pipe fittings, reduce stress concentration in connecting components, and improve the sealing performance and stability of the system. For example, in a hydraulic system, continuously distributed inclined holes on the same axis can meet the efficient docking of multi-branch pipelines or provide evenly distributed installation positioning points for specific structures. Such machining requires that the axis of the inclined hole forms a fixed angle with the axis of the pipe fitting, and multiple inclined holes need to be evenly arranged along the axial direction of the pipe fitting to ensure assembly accuracy and functional consistency.

[0003] In traditional machining processes for inclined holes in tubular components, the pipe fitting is usually fixed in a clamping tooling. By adjusting the angle of the tooling, the axis of the drilling machine is aligned with the preset inclined hole direction, and then the controller drives the drilling machine to complete the machining of a single hole. However, this method has significant limitations: Since the tooling and the pipe fitting are rigidly fixed, after each inclined hole is machined, if subsequent inclined holes need to be machined on the same axis, the operator needs to release the fixation of the pipe fitting, manually adjust its clamping position, and re-calibrate the angle. This repeated disassembly and assembly method is time-consuming and laborious, thus affecting the machining efficiency of tubular components. Summary of the Invention

[0018] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0019] The inclined hole machining device of the embodiment of the present application will be described below in conjunction with the drawings.

[0020] As Figures 1-6 shown, the inclined hole machining device of the embodiment of the present application may include a circular ring frame 1, a drilling assembly 2 and two telescopic limit assemblies 3.

[0021] Among them, the drilling assembly 2 is arranged on one side of the circular ring frame 1.

[0022] In the embodiment of the present application, the drilling assembly 2 is used to drill the pipe fitting, and the drilling assembly 2 can slide up and down on the circular ring frame 1, so as to realize the drilling of the pipe fitting.

[0023] Two telescopic limiting assemblies 3 are respectively slidably arranged in the circular ring frame 1 and are symmetrically arranged along the center line of the circular ring frame 1.

[0024] It can be understood that through the arrangement of the two telescopic limiting assemblies 3, the two ends of the pipe fitting can be limited and fixed, so as to ensure the stability of the pipe fitting and improve the oblique hole processing effect of the pipe fitting.

[0025] The telescopic limiting assembly 3 may include a limiting column 30, an abutting limiting member 31, a first electric telescopic rod 32, a pipe fitting limiting mechanism 33 and an angle sensor.

[0026] Among them, one end of the limiting column 30 is slidably arranged in the circular ring frame 1, and an installation block 302 is arranged at one end of the limiting column 30.

[0027] It can be understood that through the sliding arrangement of the limiting column 30 and the circular ring frame 1 (the circular ring frame 1 is circular), the limiting column 30 can rotate in the circular ring frame 1 and can drive the rotation and inclination of the pipe fitting, so as to adjust the drilling inclination angle of the pipe fitting.

[0028] The abutting limiting member 31 is arranged on the installation block 302, and the abutting limiting member 31 is in pressing abutment with the circular ring frame 1.

[0029] In the embodiment of the present application, after the pipe fitting is adjusted to the required angle, the abutting limiting member 31 abuts against the circular ring frame 1, so that the angle and position of the pipe fitting are fixed and limited, thus ensuring the oblique hole processing effect of the drilling assembly 2 on the pipe fitting.

[0030] The first electric telescopic rod 32 is arranged on the installation block 302, the extending shaft of the first electric telescopic rod 32 is connected to the pipe fitting limiting mechanism 33, the pipe fitting limiting mechanism 33 is sleeved on the limiting column 30 and is slidably connected to a limiting chute 301 opened on the limiting column 30.

[0031] In the embodiment of the present application, the first electric telescopic rod 32 is used to telescopically control the sliding of the pipe fitting limiting mechanism 33 on the limiting column 30. After one place of the pipe fitting is processed, the first electric telescopic rod 32 telescopically controls the movement of the pipe fitting limiting mechanism 33 and the pipe fitting, so that the unprocessed vacant position of another place moves to the lower part of the drilling assembly 2, thus realizing continuous drilling at the same axis of the pipe fitting.

[0032] It should be noted that the limiting sliding groove 301 described in this embodiment is a straight sliding groove. Through the setting of the limiting sliding groove 301, the pipe fitting limiting mechanism 33 can slide linearly on the limiting column 30, so that the pipe fitting limiting mechanism 33 drives the pipe fitting to slide linearly, thereby realizing the continuous inclined hole machining at different positions on the same axis of the pipe fitting.

[0033] The angle sensor is arranged on the limiting column 30.

[0034] It should be noted that the angle sensor described in this embodiment is used to detect the rotation angle of the limiting column 30 and transmit the angle signal to a controller (not shown in the figure). The controller issues a prompt and controls the abutting limiting member 31 to abut against the circular ring frame 1, thereby completing the angle adjustment of the pipe fitting and the limitation of the pipe fitting.

[0035] Specifically, during the actual operation, relevant operators respectively sleeved the two ends of the pipe fitting on the corresponding limiting columns 30 and operated the corresponding pipe fitting limiting mechanisms 33 to fix the ends of the pipe fitting. After the fixing is completed, after rotating the pipe fitting limiting mechanisms 33 and the pipe fitting to the specified angular position, the angle sensor transmits the signal to the controller. After receiving the signal, the controller issues a prompt and controls the abutting limiting member 31 to extend out, press against the circular ring frame 1, thereby limiting and fixing the drilling angle of the pipe fitting. Then the controller controls one of the first electric telescopic rods to extend and the other electric telescopic rod to contract, so that the pipe fitting limiting mechanism 33 drives the pipe fitting to move and moves the position to be drilled of the pipe fitting below the drilling assembly 2. The controller controls the drilling assembly 2 to move vertically to drill the position to be drilled of the pipe fitting. After the drilling at this position is completed, the controller continues to control one of the first electric telescopic rods to extend and the other electric telescopic rod to contract, so that the pipe fitting limiting mechanism 33 continues to drive the pipe fitting to move and moves another position to be drilled of the pipe fitting below the drilling assembly 2 again. The drilling assembly 2 drills at this position again. By repeating the above operations, the continuous drilling of the pipe fitting is completed. After the drilling is completed, the pipe fitting limiting mechanism 33 releases the limitation of the pipe fitting, thereby completing the operation of the inclined hole machining of the pipe fitting.

[0036] In an embodiment of the present application, as Figure 1 and Figure 4 shown, the pipe fitting limiting mechanism 33 may include a first sliding cylinder 330, a second sliding cylinder 331 and a fastener 332.

[0037] Among them, the first sliding cylinder 330 and the second sliding cylinder 331 are respectively sleeved on the limiting column 30. The second sliding cylinder 331 is arranged on one side of the first sliding cylinder 330. One end of the fastener 332 is arranged on the first sliding cylinder 330, and the other end of the fastener 332 extends above the second sliding cylinder 331 and presses against the second sliding cylinder 331.

[0038] It should be noted that the fastener 332 described in this embodiment can be a common workpiece fixing fixture on the market, and it only needs to be able to fix the pipe fitting to the second sliding cylinder 331, and there is no limitation here. In addition, the other end of the fastener 332 presses against and abuts the pipe fitting after the pipe fitting is sleeved on the limiting post 30, and presses against and abuts the second sliding cylinder 331 when the pipe fitting is not sleeved.

[0039] It can be understood that through the setting of the second sliding cylinder 331, the pipe fitting can be sleeved on the second sliding cylinder 331, and the second sliding cylinder 331 can drive the pipe fitting to move, so that the machining hole positions at different positions of the pipe fitting can be moved below the drilling assembly 2.

[0040] It should be noted that linear sliders (not shown in the figure) are respectively arranged on the first sliding cylinder 330 and the second sliding cylinder 331 described in this embodiment, and the linear sliders are respectively slidably connected to the limiting sliding grooves 301, so as to ensure the limiting sliding effect of the first sliding cylinder 330 and the second sliding cylinder 331.

[0041] In an embodiment of the present application, as Figure 1 and Figure 4 shown, the fastener 332 may include a support plate 3320, a fastening bolt 3321 and a fastening plate 3322.

[0042] Among them, one end of the support plate 3320 is arranged on the limiting post 30, the other end of the support plate 3320 extends above the second sliding cylinder 331, the fastening bolt 3321 is arranged at the other end of the support plate 3320 and is threadedly connected to the support plate 3320, the fastening plate 3322 is rotatably connected to the bottom of the fastening bolt 3321, and the fastening plate 3322 presses against and abuts the second sliding cylinder 331.

[0043] It should be noted that two fasteners 332 described in this embodiment can be provided to ensure the fixing and limiting effect of the pipe fitting on the second sliding cylinder 331. In addition, the fastening plate 3322 can be set to be arc-shaped to increase the fixing and limiting effect of the fastening plate 3322 on the pipe fitting.

[0044] In an embodiment of the present application, as Figure 1 and Figure 5 shown, the abutting and limiting member 31 may include a second electric telescopic rod 310, a plugging cylinder 311, a spring 312 and an abutting plate 313.

[0045] Among them, the second electric telescopic rod 310 is arranged on the mounting block 302, one end of the plugging cylinder 311 is slidably connected to the telescopic shaft of the second electric telescopic rod 310, the other end of the plugging cylinder 311 is connected to the abutting plate 313, the spring 312 is arranged in the plugging cylinder 311, one end of the spring 312 is connected to the extending shaft of the second electric telescopic rod 310, and the other end of the spring 312 is connected to the plugging cylinder 311.

[0046] It can be understood that by setting the spring 312, the hard contact between the second electric telescopic rod 310 and the abutting plate 313 is reduced, and a certain buffering effect can be achieved, thereby improving the service life of the abutting limiting member 31.

[0047] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the drilling assembly 2 may include a mounting plate 20, a sliding plate 21, a drilling machine 22, and a hydraulic telescopic rod 23.

[0048] Among them, the mounting plate 20 is arranged on one side of the circular ring frame 1, the sliding plate 21 is slidably arranged on the mounting plate 20, the drilling machine 22 is arranged on the sliding plate 21, the hydraulic telescopic rod 23 is arranged on the circular ring frame 1, and the extending shaft of the hydraulic telescopic rod 23 is connected to the sliding plate 21.

[0049] It should be noted that the hydraulic telescopic rod 23 described in this embodiment is connected to a hydraulic system (not shown in the figure and is a common hydraulic system on the market, and will not be described in detail here), so as to realize the telescopic movement of the hydraulic telescopic rod 23. In addition, the drilling machine 22 is a common mechanical device on the market and will not be described in detail here.

[0050] In an embodiment of the present application, as Figures 1-3 shown, the circular ring frame 1 is divided into a sliding part 10 and an abutting part 11.

[0051] Among them, one end of the limiting column 30 is slidably connected to the sliding part 10, and one end of the abutting limiting member 31 is press-abutted to the abutting part 11.

[0052] It can be understood that the settings of the sliding part 10 and the abutting part 11 ensure that the limiting column 30 can work separately from the abutting limiting member 31, improving the use effects of the limiting column 30 and the abutting limiting member 31.

[0053] It should be noted that one end of the abutting limiting member 31 described in this embodiment is press-abutted to the abutting part 11, and one end of the abutting limiting member 31 refers to the abutting plate 313 abutting against the abutting part 11.

[0054] In an embodiment of the present application, as Figures 1-3 shown, an electric control slide rail 100 is arranged on the sliding part 10, and one end of the limiting column 30 is arranged on the electric control slide rail 100.

[0055] It should be noted that the electric control slide rail 100 described in this embodiment is a common component on the market and will not be described in detail here. In addition, through the setting of the electric control slide rail 100, the controller can automatically control the rotation angle of the pipe fitting, improving the processing efficiency of the inclined holes of the pipe fitting.

[0056] In one embodiment of the present application, as Figures 1-3 shown, a friction plate is provided on the abutting portion 11, and one end of the abutting limiting member 31 is pressed against the friction plate.

[0057] It should be noted that in this embodiment, one end of the abutting limiting member 31 is pressed against the friction plate, and one end of the abutting limiting member 31 refers to the abutting plate 313 being pressed against the friction plate.

[0058] It can be understood that by providing the friction plate, the friction force between the abutting plate 313 and the abutting portion 11 is increased, thereby better limiting the inclination angle of the pipe fitting.

[0059] Specifically, during the actual operation, the relevant operators respectively socket the two ends of the pipe fitting on the corresponding limiting columns 30, and operate the corresponding fasteners 332 to fix the ends of the pipe fitting. After the fixation is completed, the controller controls the electric control slide rail 100 to do work, and the electric control slide rail 100 drives the limiting column 30 to rotate on the sliding portion 10. When the pipe fitting rotates to the specified angle, the angle sensor transmits the signal to the controller. After receiving the signal, the controller issues a prompt and controls the second electric telescopic rod 310 to extend. The second electric telescopic rod 310 extends to squeeze the spring 312 and drives the abutting plate 313 to be pressed against the friction plate, thereby limiting and fixing the drilling angle of the pipe fitting.

[0060] The controller then controls one of the first electric telescopic rods to extend and the other electric telescopic rod to contract, so that the second sliding cylinder 331 slides in the limiting chute 301, drives the pipe fitting to move, and moves the position to be drilled of the pipe fitting below the drilling machine 22. The controller controls the hydraulic telescopic rod 23 to extend, drives the sliding plate 21 and the drilling machine 22 to move vertically downward, and drills the position to be drilled of the pipe fitting.

[0061] After the drilling at this position is completed, the controller continues to control one of the first electric telescopic rods to extend and the other electric telescopic rod to contract, so that the second sliding cylinder 331 continues to drive the pipe fitting to move, and moves another position to be drilled of the pipe fitting below the drilling machine 22 again. The drilling assembly 2 drills at this position again, and repeats the above operations in this way, so as to complete the continuous drilling of the pipe fitting. After the drilling is completed, the fastener 332 releases the limitation of the pipe fitting, thereby completing the operation of machining the inclined hole of the pipe fitting.

[0062] In summary, the inclined hole machining device of the embodiment of the present application can continuously machine inclined holes and does not need to repeatedly disassemble and assemble the workpiece, thereby reducing the labor intensity of the relevant operators and improving the inclined hole machining efficiency of the pipe fitting.

[0063] The inclined hole machining device provided by the embodiment of the present application can be applied to the machining of tubular components, especially for continuously drilling multiple points on the same axis of a steel pipe, thereby improving the inclined hole machining efficiency of the steel pipe.
