Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery, in particular to a modular CNC horizontal vertical lathe. Background Art
[0002] Ball valves are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-shaped ball core and the metal valve seat with hard alloy overlay welding, making it particularly suitable for media containing fibers and tiny solid particles. When processing ball valves, CNC horizontal and vertical lathes are required.
[0003] Currently, when processing ball valves on traditional horizontal CNC lathes, the ball is fixed on the top of the lathe by clamping it with one end and supporting it with the other end. In order to achieve comprehensive processing of the ball, an additional rotary table is installed on the middle carriage of the lathe so that the position of the ball can be adjusted as needed during the processing.
[0004] However, in order to be able to pass the maximum rotation diameter, the horizontal CNC lathe itself can only be relied upon for processing. The sphere is clamped in a one-clamp and one-top manner, that is, one end is fixed by a clamp, and the other end is kept in position stable by a top support. But the problem is that the direction of gravity of the sphere and the clamping force are perpendicular to each other. In order to overcome the influence of gravity on the position stability of the sphere, the force of the top support can only be increased. However, the disadvantage of this approach is that it will cause a certain degree of deformation of the sphere during the clamping process. Especially considering that the sphere itself is a hollow part with relatively low structural strength, it is more susceptible to deformation caused by external forces. This deformation will eventually lead to large roundness errors during the processing of the sphere shape. In addition, traditional horizontal CNC lathes and their supporting equipment occupy a large area, which not only increases the space requirements of the production line, but also leads to high unit prices of equipment. More importantly, since the size of the rotary worktable is fixed, this limits the lathe's processing capabilities for ball valves of different sizes, thereby increasing R&D and manufacturing costs and reducing the lathe's adaptability.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figures 1 to 4As shown, the utility model provides a modular CNC horizontal vertical lathe, comprising a base 1, a column 2 is fixedly mounted on the top of the base 1, a separate workbench 16 is provided on one side of the outer surface of the column 2, and an electrical box 3 is provided on the side of the column 2 away from the surface of the separate workbench 16;
[0023] A processing mechanism is arranged at the top of the column 2. The processing mechanism includes a motor 4, which is fixedly connected to the top of the column 2. A screw rod 5 is fixedly installed at the output end of the column 2. The surface of the screw rod 5 is threadedly sleeved with a Z-axis slide 7. The surface of the Z-axis slide 7 is provided with an X-axis slide 8. A tool holder 10 is provided on the side of the X-axis slide 8 away from the surface of the Z-axis slide 7. A linear rail 9 is provided on the surface of the Z-axis slide 7. A mounting bracket 11 is fixedly installed at the top of the column 2. A nitrogen balancing cylinder 12 is fixedly installed at the top of the mounting bracket 11. A connecting rod 6 is provided at the bottom end of the nitrogen balancing cylinder 12. A gas tank 13 located at the top of the electric box 3 is fixedly installed on one side of the column 2. An operation panel 15 is provided on the side of the column 2 away from the surface of the X-axis slide 8.
[0024] The above scheme is adopted: the operator installs the processing tool inside the tool holder 10, and then places the sphere to be processed on the top of the separate workbench 16, and then uses the gravity of the product and the supporting force to offset each other, and slightly fixes it at the separate workbench 16. After the fixation is completed, the entire device is powered on by the electric box 3, and the operation panel 15 is used to control the motor 4 to rotate the screw rod 5. Since the screw rod 5 is threadedly connected to the Z-axis slide 7, when the screw rod 5 rotates, the Z-axis slide 7 moves, and the Z-axis slide 7 will drive the X-axis slide 8 and the tool holder 10 to move. When the X-axis slide 8 moves, it can drive the nitrogen balancing cylinder 12 and the gas tank 13. The nitrogen balancing cylinder 12 can support the entire processing mechanism, and then the tool installed inside the tool holder 10 is moved to the processing position required by the ball valve. The linear rail 9 is then driven. Since one end of the linear rail 9 is fixedly connected to the X-axis slide 8, the linear rail 9 will push the X-axis slide 8 to move on the surface of the Z-axis slide 7. The X-axis slide 8 will drive the tool holder 10 and the tool to move toward the surface of the ball valve. When the surface of the tool contacts the ball valve, the tool can be driven, and the ball valve can be processed. Finally, the motor 4 and the linear rail 9 are relatively coordinated, and the gravity of the product and the supporting force are used to offset each other, which completely overcomes the problem of deformation in the process of clamping the workpiece. Then, the nitrogen balance cylinder 12 is used to support the processing mechanism and the gas tank 13 to make the X-axis slide 8 and the tool move stably, thereby improving the processing accuracy. In addition, the device is equipped with different separate workbenches 16, which can process products of different specifications. The R&D and manufacturing costs are low and the adaptability is wide.
[0025] like Figure 1 and Figure 2As shown, the tool holder 10 is installed horizontally on one side of the X-axis slide 8, and the tool holder 10 can also be installed vertically. A bearing seat 14 located at the bottom end of the screw rod 5 is fixedly installed on the side of the column 2 close to the motor 4, and the screw rod 5 can rotate inside the bearing seat 14.
[0026] The above solution is adopted: through the design of the tool holder 10, when the tool holder 10 is installed horizontally, the tool can process a sphere, and when it is installed vertically, it can process the inner hole of a flat annular part, and the tool can process the outer diameter and end face of a flat annular part both horizontally and vertically. Through the design of the bearing seat 14, since the bearing seat 14 is arranged at the bottom end of the screw rod 5, the bearing seat 14 can support the screw rod 5 when the screw rod 5 rotates, and thus can limit and support the screw rod 5.
[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, a square protective tube 17 is provided on one side of the linear rail 9, and one end of the square protective tube 17 is fixedly connected to the X-axis slide 8. Guide rails are respectively provided on the side of the column 2 close to the motor 4 and the surface of the Z-axis slide 7, and both the Z-axis slide 7 and the X-axis slide 8 can move on the surface of the guide rails.
[0028] The above solution is adopted: through the design of the square protective tube 17, since one end of the square protective tube 17 is fixedly connected to the X-axis slide 8, the square protective tube 17 can effectively prevent external physical impact and damage, protect the cables and air pipes from damage, and extend the service life of the equipment. Through the design of the Z-axis slide 7 and the X-axis slide 8, since one side of the column 2 and the surface of the Z-axis slide 7 are provided with guide rails, the guide rails can limit the Z-axis slide 7 and the X-axis slide 8, thereby ensuring the stability of their movement.
[0029] like Figure 1 、 Figure 2 and 4 As shown, the mounting bracket 11 is located on the surface of the motor 4, and a gap is provided between the nitrogen balancing cylinder 12 and the motor 4. Various turning tools and rotary tools can be installed on one side of the X-axis slide 8.
[0030] The above scheme is adopted: through the design of the mounting bracket 11 and the nitrogen balancing cylinder 12, since the mounting bracket 11 is located on the surface of the motor 4, the motor 4 can be protected, and a gap is provided between the nitrogen balancing cylinder 12 and the motor 4, so that when the nitrogen balancing cylinder 12 and the motor 4 work at the same time, there will be no interference. Through the design of the X-axis slide 8, since various types of rotating tools and grinding wheels can be installed on one side of the X-axis slide 8, milling and grinding can be realized, and the driving component of the tool is connected to the main shaft with a reducer, thereby improving the cutting torque.
[0031] The working principle and use process of this utility model:
[0032] First, the operator can place the ball valve on the top of the separate workbench 16, and then use the product gravity and support force to offset each other, and use the clamp to slightly fix the separate workbench 16. After the fixation is completed, the operation panel 15 can be used to control the motor 4 to rotate the screw rod 5. The Z-axis slide 7 will move on the surface of the screw rod 5, and the Z-axis slide 7 will drive the X-axis slide 8 and the tool holder 10 to move. When the Z-axis slide 7 moves, the nitrogen balance cylinder 12 can be driven, and then while supporting the X-axis slide 8, the X-axis slide 8 can also be moved smoothly. Then the tool installed inside the tool holder 10 is moved to the required processing position of the ball valve, and then the linear rail 9 is driven. The linear rail 9 will push the X-axis slide 8 to move on the surface of the Z-axis slide 7. The X-axis slide 8 will drive the tool holder 10 and the tool to move toward the surface of the ball valve. When the surface of the tool contacts the ball valve, the tool can be driven, and then the ball valve can be processed, and finally the operation process is completed.
