Abstract
Description
Technical Field
[0001] This application relates to the field of machine tool technology, specifically a rotary adjustment machine tool. Background Technology
[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system that can move and process parts according to a pre-programmed program. They integrate the latest technologies in mechanics, automation, computers, measurement, and microelectronics. The basic components include a machining program carrier, a CNC device, a servo drive device, a machine tool body, and other auxiliary devices. They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other operations.
[0003] Existing CNC lathes only have the ability to adjust the X, Y, and Z axes, which cannot effectively rotate the parts on the machine. In order to achieve some detailed machining, it is necessary to further add cutting heads or set up auxiliary mechanisms to complete the rotation of the cutting heads. Adding cutting heads will increase production costs, and adding auxiliary mechanisms will require the position adjustment of the cutting head and the part to be completed separately, which is not conducive to improving the efficiency of construction. In order to solve the above problems, a rotary adjustment machine is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a rotary adjustment machine tool with advantages such as rotation function, which solves the problem that the machine tool only has the adjustment capability of X, Y, and Z axes and cannot effectively rotate the parts on the machine tool.
[0005] To achieve the above objectives, this application provides the following technical solution: A machine base is included, with a rotating groove inside the machine base, an annular rotating groove at the bottom of the rotating groove, a transmission groove inside the machine base, the transmission groove being disposed on the side of the annular rotating groove, a meshing groove between the transmission groove and the annular rotating groove, a convex rotating ring slidably connected inside the annular rotating groove, a rotating plate fixedly connected to the top of the convex rotating ring, an annular rack fixedly connected to the surface of the convex rotating ring, a rotating shaft tightly nested inside the transmission groove via bearings, a meshing gear and a worm gear fixedly connected to the surface of the rotating shaft, the side of the meshing gear and the side of the annular rack both being within the meshing groove and meshing with each other, a rotating rod tightly nested inside the transmission groove via bearings, a worm gear fixedly connected to the surface of the rotating rod, one end of the rotating rod rotating through the transmission groove and fixedly connected to a knob, the worm gear and the worm wheel meshing with each other.
[0006] With the above scheme, by setting a knob, when the angle of the rotating plate needs to be adjusted, people turn the knob to rotate the rotating rod and worm gear. Through the meshing transmission of the worm gear and worm wheel, the rotating shaft and meshing gear can be driven to rotate. Through the meshing transmission of the meshing gear and the ring rack, the rotating plate can be driven to rotate, thus making it easy for people to adjust the angle of the rotating plate. Through the speed reduction transmission of the worm gear and worm wheel, the manually input rotational force is amplified and converted into precise angle adjustment of the rotating plate. At the same time, the self-locking characteristics of the worm gear and worm wheel prevent backlash.
[0007] Furthermore, an annular angle plate is fixedly connected to the side of the machine base, and a pointer is fixedly connected to the back of the knob.
[0008] The above scheme, through the combination of a ring angle plate and a pointer, visually displays the rotation angle of the rotating plate, facilitating precise adjustment.
[0009] Furthermore, the annular angle plate is coaxial with the rotating rod.
[0010] By using the above scheme and the coaxial design of the annular angle plate and the rotating rod, the position of the annular angle plate can be determined.
[0011] Furthermore, multiple first annular grooves are provided on the inner side of the annular rotating groove and the surface of the convex rotating ring, and multiple balls are slidably connected inside the first annular grooves.
[0012] By using the above solution, the friction between the convex rotating ring and the annular rotating groove can be reduced, wear can be decreased, and the smoothness of rotation can be improved by setting the first annular groove and the ball bearing.
[0013] Furthermore, rotating grooves are provided on both opposite sides inside the rotating groove, and rotating rods are tightly nested inside the rotating grooves via bearings.
[0014] The above scheme, by setting up a rotating groove and a rotating rod, and supporting the rotating rod with bearings, can enhance structural stability.
[0015] Furthermore, two rollers are fixedly connected to the surface of the rotating rod, and two second annular grooves are formed on the surface of the rotating plate, with the roller surfaces overlapping the inner side of the second annular grooves.
[0016] By using the above solution, and by setting the roller to cooperate with the second annular groove, the friction during the movement of the rotating plate can be further reduced, ensuring smooth rotation.
[0017] Furthermore, mounting plates are fixedly connected to both sides of the machine base, and two mounting holes are opened inside the mounting plates.
[0018] The above solution, by setting up mounting plates and mounting holes, can be used to fix the entire device to external equipment or base, providing installation convenience.
[0019] Furthermore, a through hole is provided at the bottom of the machine.
[0020] The above solution, by setting through holes, allows pipelines to pass through the machine, avoiding wire tangling and improving equipment integration.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This rotary adjustment machine features a knob. To adjust the angle of the rotating plate, the operator turns the knob, causing the rotating rod and worm to rotate. The meshing of the worm and worm wheel drives the rotating shaft and meshing gear, which in turn drives the rotating plate through the meshing of the gear and ring rack. This facilitates angle adjustment. The worm gear and worm wheel reducer amplifies the manually input rotational force and converts it into precise angle adjustment of the rotating plate. The self-locking characteristic of the worm gear and worm prevents backlash. The mechanism also includes a ring angle plate and a pointer. It can intuitively display the rotation angle of the rotating plate and provide real-time angle feedback. Combined with the precision transmission of worm gears, it can achieve high-precision adjustment. The coaxial design of the annular angle plate and the rotating rod can determine the position of the annular angle plate. By setting the first annular groove and the cooperation of the ball, the friction between the convex rotating ring and the annular rotating groove can be reduced, wear can be reduced, and the smoothness of rotation can be improved. By setting the rotating groove and the rotating rod, and supporting the rotating rod with bearings, the structural stability can be enhanced. By setting the roller and the second annular groove, the friction during the movement of the rotating plate can be further reduced, ensuring smooth rotation. Attached Figure Description

A meshing gear 108 and a worm gear 109 are fixedly connected to the surface of the rotating shaft 107. The side of the meshing gear 108 and the side of the ring rack 106 are both located in the meshing groove 1022 and mesh with each other. A rotating rod 1010 is tightly nested in the inner side of the transmission groove 102 via bearings. A worm gear 1011 is fixedly connected to the surface of the rotating rod 1010. One end of the rotating rod 1010 rotates through the transmission groove 102 and is fixedly connected to a knob 1012. The worm gear 1011 meshes with the worm wheel 109. By setting the knob 1012, the rotating plate 1 can be adjusted. When adjusting the angle of 05, the user turns knob 1012, causing rotating rod 1010 and worm gear 1011 to rotate. Through the meshing transmission of worm gear 1011 and worm wheel 109, rotating shaft 107 and meshing gear 108 are driven to rotate. Through the meshing transmission of meshing gear 108 and ring rack 106, rotating plate 105 is driven to rotate, thus facilitating the adjustment of the angle of rotating plate 105. Through the reduction transmission of worm wheel 109 and worm gear 1011, the manually input rotational force is amplified and converted into precise angle adjustment of rotating plate 105. At the same time, the worm wheel 1011... The self-locking characteristic of worm gear 1011 and worm wheel 1019 prevents backflow. An annular angle plate 1014 is fixedly connected to the side of the machine base 1, and a pointer 1013 is fixedly connected to the back of the knob 1012. By setting the cooperation between the annular angle plate 1014 and the pointer 1013, the rotation angle of the rotating plate 105 is displayed intuitively, providing real-time angle feedback. Combined with the precision transmission of worm gear 109 and worm wheel 1011, high-precision adjustment is achieved. The annular angle plate 1014 and the rotating rod 1010 are coaxial. Through the coaxial design of the annular angle plate 1014 and the rotating rod 1010, the position of the annular angle plate 1014 can be determined.
[0033] Please see Figure 5Multiple first annular grooves 1015 are formed on the inner side of the annular rotating groove 103 and the surface of the convex rotating ring 104. Multiple balls 1016 are slidably connected inside the first annular grooves 1015. By setting the cooperation between the first annular grooves 1015 and the balls 1016, the friction between the convex rotating ring 104 and the annular rotating groove 103 can be reduced, wear can be reduced, and the rotation smoothness can be improved. Rotating grooves 1017 are formed on opposite sides inside the rotating groove 101. The inner side of the rotating groove 1017 is tightly nested by bearings.

The surface of the rollers 1019 overlaps the inner side of the second annular grooves 1020. By setting the rollers 1019 to cooperate with the second annular grooves 1020, the friction of the rotating plate 105 during movement can be further reduced, ensuring smooth rotation.
[0034] Please see Figure 1 and Figure 2 Mounting plates 2 are fixedly connected to both sides of the machine base 1. The mounting plates 2 have two mounting holes 201 inside. By setting the mounting plates 2 and the mounting holes 201, the entire device can be fixed to external equipment or base, providing installation convenience. The bottom of the machine base 1 has a through hole 1021. By setting the through hole 1021, the pipeline can pass through the machine base 1, avoiding wire tangling and improving the integration of the equipment.
[0035] In this embodiment, by setting the knob 1012, people can rotate the rotating plate 105 by turning the knob 1012, which makes it easy to adjust the angle of the rotating plate 105. Through the reduction transmission of the worm gear 109 and worm 1011, the manually input rotational force is amplified and converted into precise angle adjustment of the rotating plate 105. At the same time, the self-locking characteristics of the worm gear 109 and worm 1011 prevent backlash. By setting the annular angle plate 1014 and the pointer 1013, the rotation angle of the rotating plate 105 is displayed intuitively, providing real-time angle feedback. Combined with the precision transmission of the worm gear 109 and worm 1011, high-precision adjustment is achieved. Through the cooperation of the first annular groove 1015 and the ball 1016, the friction between the convex rotating ring 104 and the annular rotating groove 103 can be reduced. Through the cooperation of the roller 1019 and the second annular groove 1020, the friction during the movement of the rotating plate 105 can be further reduced, ensuring smooth rotation and making the rotating plate 105 rotate more stably.
[0036] The working principle of the above embodiment is as follows: When the angle of the rotating plate 105 needs to be adjusted, people turn the knob 1012 to rotate the rotating rod 1010 and the worm gear 1011. Through the meshing transmission of the worm gear 1011 and the worm wheel 109, the rotating shaft 107 and the meshing gear 108 can be driven to rotate. Through the meshing transmission of the meshing gear 108 and the ring rack 106, the rotating plate 105 can be driven to rotate, which makes it convenient for people to adjust the angle of the rotating plate 105. At the same time, by observing the position of the pointer 1013 and the ring angle plate 1014, it is convenient for people to make precise adjustments to the angle of the rotating plate 105.
[0037] By setting the first annular groove 1015 and the ball 1016 to cooperate, the friction between the convex rotating ring 104 and the annular rotating groove 103 can be reduced, wear can be reduced, and the rotation smoothness can be improved. By setting the rotating groove 1017 and the rotating rod 1018, and supporting the rotating rod 1018 with the bearing, the structural stability can be enhanced. By setting the roller 1019 to cooperate with the second annular groove 1020, the friction during the movement of the rotating plate 105 can be further reduced, ensuring smooth rotation.
