Description

Technical Field

[0001] The utility model relates to the technical field of square tube drilling, in particular to a square tube drilling device. Background Art

[0002] Traditional square tube processing and punching devices often use a handheld drilling machine to punch holes. When the handheld drilling machine is used for drilling, the arm bears a certain amount of machine gravity, which not only consumes a certain amount of manpower, but also sometimes causes arm shaking, which leads to inaccurate square tube punching. For this reason, a square tube processing and punching device is designed.

[0003] A Chinese utility model patent with announcement number CN219703595U discloses a square tube processing and punching device. A top plate is provided, and a first hydraulic rod is provided on the top plate, so that when it is extended and retracted, the slide rod is driven to slide in the spring frame through the connecting arm and the second connecting block, so that the slide rod is extended and retracted downward and the two ends of the square tube are pressed and fixed by the pressing block and the rubber pad. Then, the drilling rod is driven to move downward and punch holes on the square tube under the extension and retraction of the second hydraulic rod and the rotation of the rotating motor. The forward movement is all mechanical operation, which saves a certain amount of manpower, and the processing operation is more precise than that of manpower, thereby solving the problem that the traditional square tube processing and punching device often consumes a certain amount of manpower by hand.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the device is punching a hole in the square tube, it abuts and fixes the square tube from the top and bottom directions, but does not limit the square tube in the horizontal direction, so that when the square tube is punching a hole, it is easy for the square tube to shift sideways in the horizontal direction due to vibration, causing the drilling position to deviate, thereby affecting the device's drilling effect on the square tube.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example:

[0025] Please combine Figure 1-3 A square tube drilling device of the present embodiment includes a workbench 1, a drop groove is provided in the middle of the workbench 1, and a material receiving box is installed at the bottom of the drop groove to collect debris generated during drilling. A U-shaped frame 2 is installed on the top of the workbench 1, and a cylinder 3 is installed on the top of the inner wall of the U-shaped frame 2. The output end of the cylinder 3 is fixedly connected with a long plate 4, and sliding straight grooves are provided on both sides of the U-shaped frame 2. The long plate 4 is slidably arranged inside the sliding straight groove to ensure the normal movement of the long plate 4.

The top of the installation box is fixedly connected to the bottom of the long plate 4, and a drill bit 5 is fixedly connected to the output end of the drilling motor. Abutment components are installed on both sides of the long plate 4.

[0026] The abutment assembly is used to fix and limit the side of the other pipe. The abutment assembly includes a movable plate 6. An abutment wheel 7 is installed on one side of the top of the movable plate 6. The surface of the abutment wheel 7 abuts against an abutment plate 8. A movable groove is opened on the top of the workbench 1 for the abutment plate 8 to pass through, ensuring the normal lifting and lowering movement of the abutment plate 8. The top of the abutment plate 8 is fixedly connected to the bottom of the long plate 4, and an adjustment assembly is installed on one side of the movable plate 6.

[0027] The adjusting component is used to adjust the distance between the fixed plate 13 and the connecting box 9, so that the fixed plate 13 can abut against square tubes of different widths for abutment and limitation. The adjusting component includes a connecting box 9, the surface of the connecting box 9 is fixedly connected to one side of the movable plate 6, and the surface of the connecting box 9 is connected to the inner wall of the U-shaped frame 2 by two spring rods 10. The spring rod 10 includes a sleeve, and a piston rod is slidably connected to the inside of the sleeve. One side of the piston rod and one side of the inner wall of the sleeve are connected by a spring, which is convenient for resetting with the connecting box 9. A screw rod 11 is installed inside the connecting box 9, and a threaded barrel 12 is threadedly connected to the outer side of the screw rod 11. Two limit strips are fixedly connected to the surface of the threaded barrel 12. The surface of the connecting box 9 is provided with a limit strip and a screw rod. The limit groove for the movement of the threaded cylinder 12 ensures that the threaded cylinder 12 does not deflect during the movement. One end of the threaded cylinder 12 is fixedly connected to a fixed plate 13. One side of the fixed plate 13 is fixedly connected to two telescopic straight groove rods. One side of the telescopic straight groove rod is fixedly connected to the inner wall of the connecting box 9, so that the fixed plate 13 is more stable during the movement. The outer side of the screw rod 11 is sleeved with a bevel gear A14, and the surface of the bevel gear A14 is meshed and connected with a bevel gear B15. A bearing is installed on the top of the connecting box 9, and the intermediate shaft of the bevel gear B15 is installed inside the bearing. A small turntable is fixedly connected to the top of the intermediate shaft of the bevel gear B15. The bearing ensures the normal rotation of the intermediate shaft of the bevel gear B15, and the small turntable facilitates the rotation of the intermediate shaft of the bevel gear B15.

[0028] The implementation principle of a square tube drilling device in the embodiment of the present application is as follows: when drilling a hole on the opposite tube, first start the drilling motor to rotate the drill bit 5, and then start the cylinder 3, so that the cylinder 3 drives the drill bit 5 to move downward through the long plate 4 until the drilling operation on the surface of the opposite tube is completed. In this process, the long plate 4 moves downward with the two abutment plates 8, and the abutment wheel 7 is abutted by the abutment plate 8, so that the movable plate 6 moves toward the surface of the square tube, so that the connecting box 9 abuts the surface of the square tube with the fixed plate 13, and the abutment and fixation of the two sides of the opposite tube are completed. At this time, the drill bit 5 continues to move downward until the drilling operation is completed, so that when drilling a hole on the opposite tube, the two sides of the opposite tube are automatically clamped and fixed, so as to prevent the square tube from shifting sideways during drilling, thereby improving the drilling accuracy of the device.

[0029] After completing the drilling operation, the cylinder 3 drives the long plate 4 to move upward, so that the abutment plate 8 moves upward. Under the action of the spring rod 10, the abutment wheel 7 will first abut against the side of the abutment plate 8, and then move along the inclined surface of the abutment plate 8 in the direction away from the square tube, so that the fixed plate 13 releases the clamping of the other tube. After completing the drilling operation, the clamping of the other tube is automatically released, which facilitates the square tube to switch to the next drilling position, thereby improving the working efficiency of the device.

[0030] When facing square tubes of different widths, first rotate the bevel gear B15 so that the bevel gear B15 drives the screw rod 11 to rotate through the bevel gear A14, so that the threaded tube 12 moves with the fixing plate 13 in the horizontal direction, thereby adjusting the distance between the fixing plate 13 and the connecting box 9, so that during the descent of the device, the fixing plate 13 can abut against the surface of the square tube and clamp and fix the side of the square tube, thereby improving the application range of the device.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
