Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a multi-directional drilling CNC machine tool. Background Technology

[0002] A CNC lathe is a computer-controlled lathe that automatically processes workpieces according to a pre-programmed CNC program. In the process of producing workpieces, companies use CNC lathes to drill holes in the workpieces.

[0003] Existing CNC lathes generally use cylinder clamping assemblies to fix the workpiece. However, the workpiece is heavy, making it difficult for workers to move it into the CNC lathe and to easily place it inside the cylinder clamping assembly. Therefore, when fixing the workpiece, the position of the workpiece needs to be adjusted multiple times, which is inefficient and will affect the efficiency of workpiece processing.

[0004] Therefore, in order to solve the above problems, a multi-directional drilling CNC machine tool is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-directional drilling CNC machine tool to solve the problems mentioned in the background art, such as the heavy weight of the workpiece, the difficulty for workers to move the workpiece into the CNC lathe, and the inability to easily place the workpiece inside the cylinder clamping assembly. Therefore, when fixing the workpiece, it is necessary to adjust the position of the workpiece multiple times, which is inefficient and will affect the efficiency of workpiece processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-directional drilling CNC machine tool, comprising: a machine tool body, a cylinder clamping assembly installed on the inner bottom surface of the machine tool body, an upper drilling assembly installed on the inner top surface of the cylinder clamping assembly, a support structure installed on the front side of the machine tool body, and a side drilling assembly installed on one side of the cylinder clamping assembly;

[0007] A movable structure is installed on the inner side of the machine tool body. The movable structure includes a guide rail, which is fixedly installed on the bottom inner side of the machine tool body. A movable block is movably installed inside the top surface of the guide rail. A roller is fixedly installed on the bottom surface of the movable block. A hydraulic cylinder is fixedly installed on the top surface of the movable block. A receiving plate is fixedly connected to the ejector end of the hydraulic cylinder. A movable groove is opened on the side wall of the receiving plate. A ball bearing is provided on the top surface of the receiving plate.

[0008] The workpiece body is placed inside the machine tool body.

[0009] Preferably, a positioning structure is installed inside the machine tool main body. The positioning structure includes a double-headed motor fixedly installed inside the receiving plate. Output ends on both sides of the double-headed motor are fixedly connected to threaded rods. Sliders are slidably installed inside the movable grooves. Rotating shafts are movably installed inside both ends of the sliders through bearings. First toothed rings are welded to the upper and lower ends of the outer wall of the rotating shafts. Rubber cylinders are fixedly connected to the tops of the rotating shafts. A motor is fixedly installed at the inner bottom of the slider. An output end of the motor is fixedly connected to a rotating shaft. Second toothed rings are welded to the upper and lower ends of the outer wall of the rotating shaft. A transmission toothed belt is sleeved outside the rotating shaft and the second toothed ring.

[0010] Preferably, four groups of cylinder clamping components are provided. The workpiece main body is fixed inside the machine tool main body through the four groups of cylinder clamping components. The upper drilling component is located above the workpiece main body. The side drilling components are located on the left and right sides of the workpiece main body.

[0011] Preferably, the support structure is installed on the front side of the guide rail and is internally aligned. The upper end of the moving block exposes the top surface of the guide rail. The bottom end of the roller fits against the inner wall of the guide rail.

[0012] Preferably, the receiving plate is in a "middle" shape structure. The workpiece main body is placed on the top surface of the receiving plate.

[0013] Preferably, two groups of sliders are provided. The two groups of sliders are respectively installed inside the front and rear sides of the receiving plate. The threaded rods are threadedly connected to the sliders. Both ends of the sliders respectively expose the two sides of the receiving plate.

[0014] Preferably, the rotating shafts are vertically installed. Both ends of the rotating shafts respectively expose the upper and lower surfaces of the sliders. The first toothed rings are engaged with the transmission toothed belt. The surface of the rubber cylinder is in close contact with the side wall of the workpiece main body.

[0015] Preferably, the second toothed rings are engaged with the transmission toothed belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The numerical control machine tool of the present invention can move the workpiece main body to the inside of the machine tool main body through the moving structure, and the position of the workpiece main body can be adjusted through the positioning structure, so that the workpiece main body is located at the exact center of the cylinder clamping components, enabling the cylinder clamping components to accurately clamp the workpiece main body without multiple adjustments, thereby improving the fixing efficiency and effect of the workpiece main body.

[0017] The machine tool body, workpiece body, workpiece body and positioning structure are set up. Start the double-head motor to drive the threaded rod to rotate. The threaded rod is threadedly connected to the slider. The rotation of the threaded rod drives the slider to move in the movable groove. The distance between the two sets of sliders can be adjusted. When the two sets of sliders move closer to each other, they can drive the rubber cylinder to move closer to the workpiece body. The movement of the rubber cylinder can push the workpiece body, so that the workpiece body moves on the top surface of the bearing plate through the ball bearings. The position of the workpiece body on the bearing plate can be adjusted so that the support structure is centered on the bearing plate. The four sets of rubber cylinders cooperate with each other to fix the workpiece body on the bearing plate.

[0018] After one drilling operation is completed, when drilling is required at other locations on the side wall of the workpiece body, the cylinder clamping assembly is activated to release the workpiece body. Then, the motor is started, which drives the rotating shaft and the second toothed ring to rotate. The second toothed ring meshes with the transmission toothed belt, and the transmission toothed belt meshes with the first toothed ring. Therefore, the rotation of the second toothed ring drives the transmission toothed belt, and the transmission of the transmission toothed belt drives the rotating shaft to rotate through the first toothed ring. The rotation of the rotating shaft drives the rubber cylinder to rotate. The rubber cylinder is in close contact with the outer wall of the workpiece body. Therefore, the rotation of the rubber cylinder drives the workpiece body to rotate on the top surface of the bearing plate through the ball bearings. The angle of the workpiece body inside the machine tool body can be easily adjusted, which facilitates the cylinder clamping assembly to drill holes at other locations on the side wall of the workpiece body.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-8 One embodiment provided by the present invention:

[0030] The machine tool body 1, cylinder clamping assembly 11, upper drilling assembly 12, support structure 13, side drilling assembly 14, hydraulic cylinder 24, double-head motor 41, and motor 47 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0031] A multi-directional drilling CNC machine tool includes: a machine tool body 1, a cylinder clamping assembly 11 installed on the inner bottom surface of the machine tool body 1, an upper drilling assembly 12 installed on the inner top surface of the cylinder clamping assembly 11, a support structure 13 installed on the front side of the machine tool body 1, and a side drilling assembly 14 installed on one side of the cylinder clamping assembly 11.

[0032] A movable structure 2 is installed on the inner side of the machine tool body 1. The movable structure 2 includes a guide rail 21, which is fixedly installed on the bottom inner side of the machine tool body 1. A movable block 22 is movably installed inside the top surface of the guide rail 21. A roller 23 is fixedly installed on the bottom surface of the movable block 22. A hydraulic cylinder 24 is fixedly installed on the top surface of the movable block 22. A receiving plate 25 is fixedly connected to the ejector end of the hydraulic cylinder 24. A movable groove 26 is opened on the side wall of the receiving plate 25. A ball bearing 27 is provided on the top surface of the receiving plate 25.

[0033] The workpiece body 3 is placed inside the machine tool body 1. The workpiece body 3 can be moved to the inside of the machine tool body 1 by the moving structure 2, so that the workpiece body 3 can be moved conveniently within the machine tool body 1, saving manpower and improving processing safety.

[0034] Further, a positioning structure 4 is installed inside the machine tool main body 1. The positioning structure 4 includes a double-headed motor 41 which is fixedly installed inside the receiving plate 25. Output ends on both sides of the double-headed motor 41 are fixedly connected with threaded rods 42. Sliders 43 are slidably installed inside the movable slots 26. Rotating shafts 44 are movably installed inside both ends of the sliders 43 through bearings. First toothed rings 45 are welded to the upper and lower ends of the outer wall of the rotating shafts 44. Rubber cylinders 46 are fixedly connected to the tops of the rotating shafts 44. A motor 47 is fixedly installed at the inner bottom of the sliders 43. An output end of the motor 47 is fixedly connected with a rotating shaft 48. Second toothed rings 49 are welded to the upper and lower ends of the outer wall of the rotating shaft 48. A transmission toothed belt 410 is sleeved outside the rotating shafts 44 and the second toothed rings 49. The position of the workpiece main body 3 can be adjusted through the positioning structure 4, so that the workpiece main body 3 is located at the exact center of the cylinder clamping assembly 11, enabling the cylinder clamping assembly 11 to accurately clamp the workpiece main body 3 without multiple adjustments, thereby improving the fixing efficiency and effect of the workpiece main body 3.

[0035] Further, four groups of cylinder clamping assemblies 11 are provided. The workpiece main body 3 is fixed inside the machine tool main body 1 through the four groups of cylinder clamping assemblies 11. The upper drilling assembly 12 is located above the workpiece main body 3, and the side drilling assemblies 14 are located on the left and right sides of the workpiece main body 3. The four groups of cylinder clamping assemblies 11 provide limits for the installation of the workpiece main body 3 inside the machine tool main body 1, preventing the displacement of the workpiece main body 3 and affecting the processing effect.

[0036] Further, the support structure 13 is installed on the front side of the guide rail 21 and is internally aligned. The upper end of the moving block 22 protrudes from the top surface of the guide rail 21. The bottom end of the roller 23 is in contact with the inner wall of the guide rail 21. The moving block 22 can move into the support structure 13 to support it from below when the receiving plate 25 is moved out of the inside of the machine tool main body 1, making the placement of the workpiece main body 3 on the receiving plate 25 more stable. The setting of the roller 23 can reduce the friction when the moving block 22 moves.

[0037] Further, the receiving plate 25 is in a "middle" - shaped structure. The workpiece main body 3 is placed on the top surface of the receiving plate 25. The receiving plate 25 provides support for the movement of the workpiece main body 3 inside the machine tool main body 1.

[0038] Further, two groups of sliders 43 are provided. The two groups of sliders 43 are respectively installed inside the front and rear sides of the receiving plate 25. The threaded rods 42 are threadedly connected with the sliders 43. Both ends of the sliders 43 respectively protrude from both sides of the receiving plate 25. The rotation of the threaded rods 42 can drive the sliders 43 to move inside the receiving plate 25, adjusting the distance between the two groups of sliders 43, facilitating the movement of the workpiece main body 3 through the rubber cylinders 46, adjusting the position of the workpiece main body 3, and pre - fixing the workpiece main body 3.

[0039] Furthermore, the rotating shaft 44 is installed vertically, with its two ends exposed above and below the slider 43. The first toothed ring 45 meshes with the transmission toothed belt 410, and the surface of the rubber cylinder 46 is in close contact with the side wall of the workpiece body 3. The transmission of the transmission toothed belt 410 can drive the rotating shaft 44 to rotate through the first toothed ring 45, providing power for the rotation of the rubber cylinder 46. This rotation of the rubber cylinder 46 can drive the workpiece body 3 to rotate on the top surface of the receiving plate 25, thereby adjusting the angle of the workpiece body 3 and achieving full processing of the side wall of the workpiece body 3.

[0040] Furthermore, the second toothed ring 49 meshes with the transmission toothed belt 410, and the rotation of the second toothed ring 49 by the motor 47 can drive the transmission toothed belt 410 to make the two sets of rubber cylinders 46 rotate in the same direction and at the same speed, so that the adjustment of the angle of the workpiece body 3 is smoother and more stable.

[0041] Working principle: Before drilling, pull the support plate 25. The support plate 25 moves forward on the guide rail 21 via the roller 23. The support plate 25 can be moved to the support structure 13 via the guide rail 21. The support plate 25 can be moved to the outside of the machine tool body 1. Use the hoisting equipment to place the workpiece body 3 on the support plate 25. Start the double-head motor 41 to drive the threaded rod 42 to rotate. The threaded rod 42 is threadedly connected to the slider 43. The rotation of the threaded rod 42 drives the slider 43 to move in the movable groove 26. The distance between the two sets of sliders 43 can be adjusted. The two sets of sliders 43 move closer to each other, which can drive the rubber cylinder 46 to move closer to the workpiece body 3. The movement of the rubber cylinder 46 can push the workpiece body 3, so that the workpiece body 3 moves on the top surface of the support plate 25 via the ball bearing 27. The position of the workpiece body 3 on the support plate 25 can be adjusted so that the support structure 13 is centered on the support plate 25. The four sets of rubber cylinders 46 cooperate with each other to fix the workpiece body 3 on the support plate 25.

[0042] Push the receiving plate 25, and the receiving plate 25 will reset on the guide rail 21. The receiving plate 25 will then move the workpiece body 3 into the machine tool body 1. Start the hydraulic cylinder 24 to lower the receiving plate 25, so that the workpiece body 3 on the receiving plate 25 is lowered to the center position of the four sets of cylinder clamping assemblies 11, so that the four sets of cylinder clamping assemblies 11 can fix the workpiece body 3. The top surface and side wall of the workpiece body 3 can be drilled by the upper drilling assembly 12 and the side drilling assembly 14 respectively.

[0043] When drilling is completed and other holes need to be drilled on the side wall of the workpiece body 3, the cylinder clamping assembly 11 is activated to release the workpiece body 3. Then, the motor 47 is started, which drives the rotating shaft 48 and the second toothed ring 49 to rotate. The second toothed ring 49 meshes with the transmission toothed belt 410, and the transmission toothed belt 410 meshes with the first toothed ring 45. Therefore, the rotation of the second toothed ring 49 can drive the transmission toothed belt 410 to drive. The transmission of the transmission toothed belt 410 can drive the rotating shaft 44 to rotate through the first toothed ring 45. The rotation of the rotating shaft 44 drives the rubber cylinder 46 to rotate. The rubber cylinder 46 is in close contact with the outer wall of the workpiece body 3. Therefore, the rotation of the rubber cylinder 46 drives the workpiece body 3 to rotate on the top surface of the bearing plate 25 through the ball bearing 27. The angle of the workpiece body 3 inside the machine tool body 1 can be easily adjusted, which facilitates the cylinder clamping assembly 11 to drill holes on other positions of the side wall of the workpiece body 3.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
