Description

Technical Field

[0001] The present invention relates to the technical field of punching and drilling devices, and particularly to a drilling device for round tube processing. Background Art

[0002] A punching device is a kind of equipment used to punch holes in materials during mechanical production. At present, when the punching device punches holes, the driving part and the drill rod directly contact the material, so that the material is pressed out of the hole by the drilling. During this process, the operator directly inserts the material into the punching device for stamping. Among them, for solid materials, no deformation will occur during punching. However, for materials with a hollow inner side and a relatively thin inner diameter, since the inner side is not supported and directly forms a shape with the drill rod during stamping, during the stamping process, the surface near the punched hole of the material will deform, such as being tortuous or wrinkled, resulting in the hollow material being affected during stamping.

[0003] Chinese invention patent, application publication number CN114472694A discloses a drilling device for round tube processing. It includes an engineering table, on which a driving part is provided. The driving part at least includes a fixing plate, a notch is formed on the surface of the fixing plate, a limiting plate is arranged inside the notch, there are multiple groups of limiting plates, the limiting plates form a rectangle, connecting plates are installed on the limiting plates, connection ports are formed on the surfaces of the connecting plates, and the connection ports are connected by connection bolts. The side surface of the limiting plate is connected with a positioning plate by bolts, and a cylinder is installed on the engineering table, and a rod body is connected to the bottom of the cylinder. By moving adjacent connecting plates closer or farther away and locking the connection bolts, the inner diameter of the limiting plate can be adapted to the material, and the material is sleeved outside the limiting plate. The limiting plate provides stable support for the material, and the cylinder punches holes in the material, achieving convenient punching and drilling. Since the inner wall of the material is supported and fixed, the hollow material will not deform during punching and drilling.

[0004] The above solution is for punching and drilling square pipe bodies. During punching and drilling, the position of the pipe body where the hole is drilled is prone to deformation, and the punching and drilling device in the above solution does not support the position of the pipe body where the hole is drilled, resulting in the position of the pipe body where the hole is drilled being prone to deformation and reducing the product quality.

DETAILED DESCRIPTION OF THE INVENTION

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The punching device is a kind of equipment used for opening holes in materials during mechanical production. At present, when the punching device is opening holes, the driving part and the drill rod directly contact the material, so that the material is pressed out of the hole position by the drilling. During this process, the operator directly inserts the material into the punching device for stamping. Among them, for solid materials, no deformation will occur during punching. However, for materials with a hollow inside and a relatively thin inner diameter, since the inside is not supported and directly forms a shape with the drill rod during stamping, during the stamping process, the surface near the opening of the material will deform, such as: twisting and wrinkling, resulting in the hollow material being affected during stamping.

[0031] This solution is used for unidirectional punching of circular pipe bodies, and the circular pipe bodies after punching can be used as grouting pipes.

[0032] Embodiment 1: As Figure 1 - Figure 2 and Figure 5 - Figure 6 shown, the present invention provides a technical solution: a drilling device for circular pipe processing, including a support table 1, a support frame 2, and a punching and drilling assembly 201 provided at the bottom of the support frame 2. The punching and drilling assembly 201 includes a drill bit. The punching and drilling assembly 201 has been disclosed in a drilling device for circular pipe processing with the application publication number CN114472694A, and this solution will not be elaborated here. A baffle 5 is provided on the side of the support frame 2. The front projection of the baffle 5 can be rectangular or circular. When the front projection of the baffle 5 is rectangular, the length of the largest side of the baffle 5 is greater than the outer diameter of the pipe body 10. When the front projection of the baffle 5 is circular, the diameter of the baffle 5 is greater than the outer diameter of the pipe body 10.

[0033] A fixing rod 6 is fixed on the side of the baffle 5, and a support assembly 7 is provided outside the fixing rod 6. Among them, the support assembly 7 includes two arc-shaped support plates 701, and the two arc-shaped support plates 701 of the support assembly 7 are symmetrically distributed at the top and bottom of the fixing rod 6. A number of equally spaced through holes 702 are provided on the plate body of the arc-shaped support plate 701 at the top. In this way, when the drill bit of the punching and drilling assembly 201 moves vertically, it can movably penetrate through the through holes 702, so as to punch and drill the top of the circular pipe 10 supported by the support assembly 7. The spacing distance of the through holes 702 depends on the hole spacing of the circular pipe punching.

[0034] The supporting assembly 7 further includes a driving member. The driving member of the supporting assembly 7 is arranged between two arc-shaped supporting plates 701. The two arc-shaped supporting plates 701 are driven to move towards or away from each other by the driving member. It should be noted that the outer arc surfaces of the two arc-shaped supporting plates 701 are adapted to the inner arc surface of the pipe body 10. That is, when the driving member drives the two arc-shaped supporting plates 701 to move away from each other to support the pipe body 10, the outer arc surfaces of the arc-shaped supporting plates 701 are in contact with the inner arc surface of the pipe body 10.

[0035] As Figure 5 and Figure 6 shown, the driving member includes a motor 710, a movable shaft 708 movably arranged in the fixed rod 6, and a rotating shaft 703 movably connected to the fixed rod 6. There are a plurality of rotating shafts 703, which are horizontally distributed along the fixed rod 6, and the distances between the rotating shafts 703 are equal. The output end of the motor 710 is fixed to the end of the movable shaft 708. That is, the motor 710 drives the movable shaft 708 to rotate. Screws with opposite thread directions are respectively formed on the rod bodies on both sides of the rotating shaft 703, and a thread block 704 is movably screwed on the rod body of the screw. Connecting shafts 705 are arranged on both sides of the arc-shaped supporting plate 701. An articulated rod 706 is arranged between the connecting shaft 705 on one side and the thread block 704, and both sides of the articulated rod 706 are movably connected to the connecting shaft 705 and the thread block 704 respectively;

[0036] To realize the rotation of the rotating shaft 703, a worm gear 707 is fixed on the shaft body of the rotating shaft 703, and a number of worm shafts 709 equal to the number of worm gears 707 are arranged on the shaft body of the movable shaft 708, and the worm gear 707 is engaged with the worm shaft 709. In this way, when the worm shaft 709 rotates to drive the worm gear 707 to rotate, the two thread blocks 704 move towards or away from each other, so as to realize the separation from and support of the inner wall of the pipe body 10 by the two arc-shaped supporting plates 701.

[0037] Embodiment 2: On the basis of Embodiment 1, in order to prevent the drilling shift caused by the deflection of the fixed rod 6, a pressing assembly 8 is arranged on the side surface of the support frame 2. Specifically, as Figure 3 and Figure 4 shown, the pressing assembly 8 includes a support block 801 fixed to the support frame 2. A pressing plate 802 is arranged on the side surface of the support block 801. When the right projection of the pressing plate 802 is circular, the diameter of the pressing plate 802 is equal to or greater than the outer diameter of the pipe body 10. A second hydraulic cylinder 805 is fixed on one side of the support block 801, and the telescopic end of the second hydraulic cylinder 805 is fixed to the side surface of the pressing plate 802. A first extension plate 803 is arranged on the side surface of the pressing plate 802. When drilling, as Figure 4As shown in the figure, the side surface of the first extension plate 803 is pressed against the end of the pipe body 10. In this way, when installing the pipe body 10, since the first extension plate 803 pushes the pipe body 10, the other end of the pipe body 10 is pressed against the side surface of the baffle 5. Under the supporting force of the arc-shaped supporting plate 701 on the pipe body 10, and the pressing forces of the first extension plate 803 and the baffle 5 on the pipe body 10, the positioning of the pipe body 10 is achieved, avoiding the deflection of the fixing rod 6 due to single force, and ensuring the accuracy of the punching and drilling position.

[0038] Embodiment 3: To further improve the stability of the fixing rod 6 and the pipe body 10 when vertically stressed, on the basis of Embodiment 2, a pressure-bearing block 11 is provided on the side surface of the fixing rod 6, and a second extension plate 804 is provided on the plate body of the pressure-bearing plate 802. During punching and drilling, the side surface of the second extension plate 804 is pressed against the end of the pressure-bearing block 11. To reduce the torque on the second hydraulic cylinder 805 and improve its service life, a number of equally spaced pressure-bearing rods 806 are fixed on the plate body of the pressure-bearing plate 802, and the pressure-bearing rods 806 are movably inserted into the support blocks 801.

[0039] Embodiment 4: To facilitate the feeding before punching and drilling the pipe body 10 and the discharging after punching and drilling, on the basis of Embodiment 1 or Embodiments 1 to 4, as Figure 1 shown in the figure, a rotating rod 3 is movably connected to one side of the support frame 2 through a movable rod, and the baffle 5 is fixed to the end of the rotating rod 3. A first hydraulic cylinder 4 is provided between the rotating rod 3 and the support frame 2. In this way, when the first hydraulic cylinder 4 expands and contracts, it drives the rotating rod 3 to rotate along the axis of the movable rod.

[0040] As Figure 1 shown in the figure, a transmission member 9 is provided at the bottom of the support table 1. The transmission member 9 is composed of a transmission motor, rollers, a conveyor belt 901 and other components, which are mature existing technologies and will not be elaborated in this solution. A guide groove 902 is provided on the conveyor belt 901 of the transmission member 9. The guide groove 902 is adapted to the pipe body 10, and the guide groove 902 is located directly below the support assembly 7. In this way, after the transmission member 9 is started, the conveyor belt 901 can drive the pipe body 10 in the guide groove 902 to be conveyed.

[0041] For the supplement of this solution, when installing the pipe body 10, the pipe body 10 is placed in the guide groove 902 of the conveyor belt 901. At this time, the fixing rod 6 and the support assembly 7 are located Figure 7The position shown, i.e., the fixed rod 6 is parallel to the conveyor belt 901. The controller controls the transmission member 9 to start, and the conveyor belt 901 drives the pipe body 10 to move upward until the pipe body 10 is inserted into the fixed rod 6 and the support assembly 7. The controller controls the first hydraulic cylinder 4 to contract until the fixed rod 6 and the support assembly 7 are parallel to the support table 1. The controller controls the motor 710 to start. When the worm 709 rotates to drive the worm wheel 707 to rotate, the two wire blocks 704 move towards each other, realizing the support of the inner wall of the pipe body 10 by the two arc-shaped support plates 701. The controller controls the second hydraulic cylinder 805 to extend. At this time, the other end of the pipe body 10 is pressed against the side surface of the baffle 5. Under the support force of the arc-shaped support plate 701 on the pipe body 10, the extrusion force of the first extension plate 803 and the baffle 5 on the pipe body 10, the positioning of the pipe body 10 is realized. The punching and drilling assembly 201 is controlled to punch and drill the pipe body 10. After the punching and drilling are completed, the controller controls the second hydraulic cylinder 805 to reset, and then controls the first hydraulic cylinder 4 to reset. The processed pipe body 10 is again located at Figure 7 the position shown. The controller controls the motor 710 to rotate in the reverse direction, and the support assembly 7 is disengaged from the pipe body 10. At this time, the pipe body 10 is in contact with the conveyor belt 901. The controller controls the transmission member 9 to rotate in the reverse direction, and the conveyor belt 901 drives the pipe body 10 to move downward to realize unloading.
