[0002] An automated CNC lathe is a machine tool that uses advanced digital control technology to achieve automated machining operations through pre-programmed instructions. It can efficiently and accurately complete machining tasks such as cutting and drilling of various complex parts.

[0003] Currently, existing automated CNC lathes require the metal tube to be clamped by a fixture before drilling holes in the outer wall of a metal tube. The tube's position is then continuously adjusted before the drill bit is used to drill the hole in the outer wall of the tube.

[0004] Currently, when drilling holes in the outer wall of a round tube, workers often need to drill holes in a circular array on the same outer wall, meaning that the spacing between each pair of holes is consistent. After completing the drilling operation for one hole, workers often need to manually remove the round tube and readjust its position to facilitate subsequent drilling, which is quite troublesome. Therefore, an automated CNC lathe drilling device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automated CNC lathe drilling device, which aims to improve the problem in the prior art that when drilling a circumferential array of holes on the outer wall of a round tube, it is necessary to remove the round tube multiple times and re-fix it, which is quite troublesome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automated CNC lathe drilling device, comprising a machine body, a rotating shaft rotatably connected through the inner wall of the machine body, a clamp fixedly connected to the right end of the rotating shaft, an electric telescopic rod fixedly connected to the inner wall of the machine body, an installation plate fixedly connected to the output end of the electric telescopic rod, a motor fixedly connected to the bottom end of the installation plate, a drill bit fixedly connected to the output shaft of the motor, a rotating mechanism jointly provided on the outer wall of the installation plate and the outer side of the rotating shaft, the rotating mechanism including a connecting rod, the front end of the connecting rod fixedly connected to the rear end of the installation plate, a sliding groove provided on the inner wall of the connecting rod, an opening block rotatably connected to the inner wall of the sliding groove, a control block rotatably connected to the inner wall of the opening block, a gear one fixedly connected to the outer wall of the rotating shaft, a gear two rotatably connected to the inner wall of the machine body, and an adjustment component provided inside the connecting rod.

[0007] As a further description of the above technical solution:

[0008] The adjustment assembly includes an electric telescopic rod II, the bottom end of which is fixedly connected to a moving bar. The inner wall of the opening block is provided with a control groove, and the inner wall of the opening block and the inner wall of the sliding groove are elastically connected by a spring.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the body is provided with a sliding groove, and the outer wall of the mounting plate is slidably connected to the inner wall of the sliding groove.

[0011] As a further description of the above technical solution:

[0012] The bottom end of the control block is elastically connected to the inner wall of the opening block by a spring sheet.

[0013] As a further description of the above technical solution:

[0014] The mounting plate is rectangular in shape, and a rectangular protrusion is provided on the right rear side of the mounting plate.

[0015] As a further description of the above technical solution:

[0016] The number of sliding grooves is set to multiple, and the multiple sliding grooves are arranged in a straight line array in the vertical direction.

[0017] As a further description of the above technical solution:

[0018] The control block is rectangular in shape, and the rotatable connection between the control block and the opening block is located above the rear end of the control block.

[0019] As a further description of the above technical solution:

[0020] The movable bar is rectangular in shape, and its bottom end is chamfered.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a connecting rod, sliding groove, opening block, control block, spring, gear one, and gear two, it is ensured that after the mounting plate drives the drill bit to complete a drilling operation, it will not drive the clamp and the round tube to rotate together during the reset process. However, when it moves downward again, it can drive the clamp and the round tube to move. After completing a drilling operation, the round tube will automatically rotate, thereby ensuring that when drilling the outer wall of the round tube, it is not necessary to remove the round tube and re-fix it, thus improving work efficiency.

[0023] 2. In this utility model, the electric telescopic rod II, the moving bar, the control groove, the spring, and the connecting rod are designed to ensure that the operator can adjust the number of control blocks used to drive the gear II to rotate according to actual needs. This ensures that when the operator needs to drill a specified number of holes in the outer wall of the round tube, a better adjustment effect can be achieved. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2This utility model provides an embodiment of an automated CNC lathe drilling device, comprising a body 1, with a rotating shaft 2 rotatably connected through and rotatably to the inner wall of the body 1. The rotating shaft 2 is cylindrical, and a clamp 3 is fixedly connected to the right end of the rotating shaft 2. The clamp 3 is used to clamp a cylindrical workpiece. This technology is prior art and can be implemented by those skilled in the art, so it will not be described in detail in this case. An electric telescopic rod 4 is fixedly connected to the inner wall of the body 1. The extension and retraction direction of the output end of the electric telescopic rod 4 is vertical. The output end of the telescopic rod 4 is fixedly connected to a mounting plate 5. The mounting plate 5 is cuboid in shape, and a cuboid protrusion is provided on the right rear side of the mounting plate 5. A sliding groove 9 is provided on the inner wall of the machine body 1. The outer wall of the mounting plate 5 is slidably connected to the inner wall of the sliding groove 9. The cuboid protrusion of the mounting plate 5 is slidably connected to the inner wall of the sliding groove 9. A motor 6 is fixedly connected to the bottom end of the mounting plate 5. A drill bit 7 is fixedly connected to the output shaft of the motor 6. Through the setting of the motor 6 and the drill bit 7, it is ensured that the drill bit 7 can rotate under the drive of the motor 6 to achieve the drilling effect.

[0034] Reference Figure 2 The outer wall of the mounting plate 5 and the outer side of the rotating shaft 2 are provided with a rotating mechanism 8. The rotating mechanism 8 includes a connecting rod 81. The connecting rod 81 is cuboid in shape and has a vertical groove inside. The front end of the connecting rod 81 is fixedly connected to the rear end of the mounting plate 5.

[0035] Reference Figure 4 - Figure 6 The inner wall of the connecting rod 81 is provided with a sliding groove 82. The number of sliding grooves 82 is set to multiple, and the multiple sliding grooves 82 are arranged in a straight line array in the vertical direction. An opening block 83 is rotatably connected to the inner wall of the sliding groove 82. The opening block 83 is cuboid in shape and has an opening at its front end. A control block 84 is rotatably connected to the inner wall of the opening block 83. The control block 84 is cuboid in shape and is rotatably connected to the opening block 83 at a position above the rear end of the control block 84. The bottom end of the control block 84 is elastically connected to the inner wall of the opening block 83 by a spring piece 85. One end of the spring piece 85 is fixedly connected to the bottom end of the control block 84, and the other end of the spring piece 85 is fixedly connected to the inner wall of the opening block 83. A gear 1 86 is fixedly connected to the outer wall of the rotating shaft 2, and a gear 2 87 is rotatably connected to the inner wall of the body 1. Gear 1 86 and gear 2 87 mesh.

[0036] Reference Figure 3 - Figure 5The connecting rod 81 is internally provided with an adjustment component 10, which includes an electric telescopic rod 101. The bottom end of the electric telescopic rod 101 is fixedly connected to a moving bar 102. The moving bar 102 is rectangular in shape and has a chamfer at its bottom end. The inner wall of the opening block 83 is provided with a control groove 103. By setting the chamfer, it is ensured that the front end of the moving bar 102 is longer than the rear end, so that the opening block 83 can be moved backward by the front end of the moving bar 102 entering the control groove 103. The inner wall of the opening block 83 is elastically connected to the inner wall of the sliding groove 82 by a spring 104. One end of the spring 104 is fixedly connected to the inner wall of the opening block 83, and the other end of the spring 104 is fixedly connected to the inner wall of the sliding groove 82.

[0037] Working principle: When in use, the operator clamps the cylindrical workpiece with the clamp 3, and then starts the electric telescopic rod 4 and the motor 6, so that the electric telescopic rod 4 drives the drill bit 7 to move downward, and at the same time the motor 6 drives the drill bit 7 to rotate, so as to achieve the drilling operation.

[0038] After drilling is completed, the worker moves the mounting plate 5 upward using the electric telescopic rod 4. This causes the mounting plate 5 to move the connecting rod 81 upward, which in turn causes the control block 84 to move upward. Since the control block 84 and the connecting rod 81 are connected at the top, the control block 84 can deflect at this time. Therefore, the control block 84 rotates, but it will not drive the gear 87 to rotate.

[0039] When the electric telescopic rod 4 continues to drive the mounting plate 5 and drill bit 7 downward, it drives the connecting rod 81 downward, which in turn drives the control block 84 downward. Since the rotational connection between the control block 84 and the connecting rod 81 is located at the top, the control block 84 cannot deflect at this time. Therefore, the control block 84 drives the gear 2 87 to rotate, and through the gear 2 87, it drives the gear 1 86 to rotate, which in turn drives the rotating shaft 2 and the clamp 3 to rotate, thus causing the round tube workpiece to rotate. This ensures that when the drill bit 7 drills again, it can drill the rotated workpiece.

[0040] When it is necessary to adjust the angle between the two holes of the drilled round pipe, the operator starts the electric telescopic rod 101, which causes the moving bar 102 to move downward. This causes the inclined surface of the moving bar 102 to enter the control groove 103, thereby causing part of the opening block 83 to move backward. This prevents the control block 84 inside the opening block 83 from contacting the gear 87, thereby reducing the angle of each rotation of the shaft 2 and achieving the effect of adjusting the spacing.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
