Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a machine tool base with a dual drive control system. Background Technology

[0002] Multi-station CNC machine tools have different requirements for the operating state of the base due to different processing technology. Sometimes the base needs to be rotated at high speed, while other times only the base needs to be adjusted to adjust the processing position. In the existing technology, the same rotation control system is used for both high-speed rotation and position adjustment. This results in inaccurate adjustment of the base position during position adjustment and poor fixed rigidity after adjustment. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a machine tool base with a dual drive control system, which has the advantages of accurate position adjustment, good adjustment rigidity, and stable operation.

[0004] This utility model provides a machine tool base with a dual-drive control system, including a housing, a support platform, a first control system, a second control system, and a connecting assembly. The support platform is rotatably mounted on the surface of the housing. The first control system is located on one side of the support platform and connected to the side wall of the support platform to drive its rotation. A transmission rod is coaxially mounted on the support platform, and a first end gear is provided at the bottom end of the transmission rod. The second control system is rotatably coaxially mounted below the transmission rod and has an axially arranged channel. A power ring is provided on the side of the channel near the transmission rod, and a second end gear is provided at the bottom of the power ring. The connecting assembly includes a lifting component and a connecting plate. The connecting plate is located below the power ring and connected to the lifting component. A third end gear is provided at the top of the connecting plate. When adjusting the position, the connecting plate moves upward and simultaneously engages with the bottom of the power ring and the bottom of the transmission rod.

[0005] Furthermore, the second control system includes a fixed base, a rotating base, and a worm gear drive. The fixed base is fixedly connected to the housing. The rotating base is rotatably disposed within the fixed base and has a worm gear on its outer ring. The worm gear drive is disposed on one side of the rotating base and meshes with the worm gear to drive its rotation.

[0006] Furthermore, the second control system also includes a buffer assembly. The outer ring of the rotating seat is provided with an extension piece. The buffer assembly is circumferentially disposed on the rotating seat and connected to the fixed seat. The buffer assembly is provided with a groove in which the extension piece can be inserted. A movable block is provided below the groove. Oil is injected into the movable block to make the movable block move up and down, thereby clamping the extension piece and stopping the rotating seat.

[0007] Furthermore, the first control system includes a rotary drive and a transmission gear, and the outer ring of the support platform is provided with driven teeth. The transmission gear is connected to the rotary drive and meshes with the driven teeth.

[0008] By adopting the above technical solution, the beneficial effects of this utility model are:

[0009] This invention achieves a transmission connection between the second control system and the support platform by setting a connecting component, enabling independent operation of the two control systems and preventing the second control system from affecting the first control system; by setting a worm gear to drive the rotation of the second control system, the driving rigidity and adjustment accuracy of the second control system are improved, making the position adjustment more stable; by setting a buffer component to assist the stopping of the rotating seat in the second control system, a rapid and smooth transition between the operation of the two systems is achieved.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0034] Reference Figure 1-7 This utility model provides a machine tool base with a dual drive control system, including a housing 1, a support platform 2, a first control system 3, a second control system 4, and a connecting component 5.

[0035] The support platform 2 is rotatably mounted on the surface of the housing 1 for placing and fixing the workpieces to be processed. The first control system 3 is located on one side of the support platform 2 and connected to the side wall of the support platform 2 to drive its rotation. The specific driving method is as follows: the first control system 3 includes a rotary drive component 31 and a transmission gear 32. Then, the outer ring of the support platform 2 is provided with driven teeth. The transmission gear 32 is connected to the rotary drive component 31 and meshes with the driven teeth. The transmission gear 32 and the rotary drive component 31 can be connected by a conveyor belt or gears.

[0036] A transmission rod 21 is coaxially mounted on the support platform 2, and a first end gear is provided at the bottom end of the transmission rod 21. The second control system 4 is rotatably coaxially mounted below the transmission rod 21. The second control system 4 has a channel 41 along the axial direction. A power ring 42 is provided on the side of the channel 41 near the transmission rod 21. A second end gear is provided at the bottom of the power ring 42. The first end gear and the second end gear are flush. The connecting assembly 5 includes a lifting member 51 and a connecting plate 52. The connecting plate 52 is located below the power ring 42 and is connected to the lifting member 51. A third end gear is provided at the top of the connecting plate 52. When adjusting the position, the connecting plate 52 moves upward and simultaneously meshes with the bottom of the power ring 42 and the bottom of the transmission rod 21.

[0037] In order to increase the control accuracy and transmission rigidity of the second control system 4, the second control system 4 includes a fixed base 43, a rotating base 44 and a worm gear drive 45. The fixed base 43 is fixedly connected to the housing 1. The rotating base 44 is rotatably disposed in the fixed base 43 and its outer ring is provided with a worm gear. At this time, the channel 41 and the power ring 42 are both disposed on the rotating base 44. The worm gear drive 45 is disposed on one side of the rotating base 44 and meshes with the worm gear to drive its rotation.

[0038] In order to achieve the switching of the master control of different control systems, the second control system 4 also includes a buffer assembly 46. The outer ring of the rotary seat 44 is provided with an extension piece 441, which is preferably annular. The buffer assembly 46 is arranged around the rotary seat 44 and connected to the fixed seat 43. The buffer assembly 46 is provided with a groove for the extension piece 441 to be inserted. A movable block 461 is provided below the groove. Oil is injected into the movable block 461 to make the movable block 461 move up and down, thereby clamping the extension piece 441 and stopping the rotary seat 44. The oil injection method is to provide an oil injection port on the side wall of the fixed seat 43.

[0039] Working principle: When the base rotates at high speed, the connecting plate 52 separates from the power ring 42 and the transmission rod 21; when the base is adjusted, the first control system 3 stops working, and then the lifting component 51 is activated to control the connecting plate 52 to simultaneously engage with the transmission rod 21 and the power ring 42, realizing the connection between the second control system 4 and the support platform 2. Then, the worm gear drive component 45 is activated to precisely adjust the rotation angle of the support platform 2.
