Abstract
Description
Technical Field
[0001] This utility model relates to the field of tap thread processing technology, and in particular to a tilting angle device for a CNC thread grinding machine. Background Technology
[0002] Machine tools are used in the manufacture of various high-precision and high-efficiency machinery. As high-end motion machinery (including IC equipment, feed mechanisms for precision instruments, etc.) and high-end CNC machine tools develop towards higher speed, higher precision, and higher reliability, lead screws and nuts have become key components. With the continuous development and changes in market demands, the styles of threaded components such as ball screws and worm gears, as well as internally threaded components such as nuts and modules, are becoming increasingly diverse.
[0003] Chinese patent CN214684613U discloses a fully automatic tilting-angle CNC grinding machine for internal threads, belonging to the field of grinding machines. It includes a machine body, a Z-axis moving mechanism sliding along the Z-axis, with a workpiece spindle mounted on the Z-axis, and an X-axis moving mechanism sliding along the X-axis, with a grinding wheel spindle and a tilting-angle mechanism mounted on the X-axis. This fully automatic tilting-angle CNC grinding machine for internal threads uses a servo motor and reducer to drive and connect the grinding wheel spindle, adjusting the machining tilting angle of the grinding wheel spindle. Compared to traditional grinding machines, its tilting angle adjustment range is larger, theoretically achieving any tilting angle within 360°, facilitating adjustment. Furthermore, the tilting-angle mechanism in this grinding machine structure features high precision, simple operation, and visual angle measurement, thus improving processing efficiency and accuracy.
[0004] However, this technical solution has a large vibration amplitude when the grinding wheel swings, which is not stable enough and will cause the grinding wheel to shift in position. This will result in errors when the grinding wheel is used to process threads, resulting in low processing accuracy, which does not meet the actual use requirements and has a low yield. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a tilting device for a CNC thread grinding machine. By installing an indexing turntable between the tilting mechanism and the drive component, the tilting mechanism can quickly and accurately rotate to the designated position with minimal error, thus ensuring machining accuracy and improving work efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A tilting device for a CNC thread grinding machine includes: a driving component, a tilting mechanism disposed at the output end of the driving component, and a grinding mechanism disposed on the tilting mechanism. An indexing turntable for precisely controlling the rotation angle of the tilting mechanism is disposed between the tilting mechanism and the driving component.
[0008] Preferably, the swing mechanism includes: a rotating seat rotatably connected to the driving member and a receiving seat disposed on the rotating seat.
[0009] Preferably, the indexing turntable is provided between the rotating base and the driving component.
[0010] Preferably, the indexing turntable is fixedly connected to the rotating base and rotatably connected to the output end of the drive component.
[0011] Preferably, the rotating seat and the receiving seat are rigidly connected.
[0012] Preferably, the receiving seat is provided with a main shaft, and the main shaft is connected to the grinding mechanism.
[0013] Preferably, the grinding mechanism includes: a mounting base rotatably connected to the spindle, a grinding wheel mounted on the mounting base, and a dynamic balancing assembly disposed close to the grinding wheel.
[0014] Preferably, the dynamic balancing assembly includes: a balancing head disposed at one end of the grinding wheel and a detector disposed at the other end of the grinding wheel.
[0015] Preferably, the detector is disposed on the main shaft.
[0016] The beneficial effects of this utility model are as follows:
[0017] (1) This utility model drives the rotating seat to rotate through the indexing turntable, and the rotating seat then drives the receiving seat to rotate. The whole process is simple to operate and easy to use. Moreover, its structure is compact and can ensure the stability of the grinding mechanism during rotation. The grinding wheel will not deviate during processing, and the precision is high.
[0018] (2) By installing the dynamic balancing component on the spindle, the dynamic balancing component can be automatically adjusted according to the actual situation of the grinding wheel, thereby reducing the vibration amplitude of the grinding wheel during operation, improving the stability of the grinding wheel, and thus ensuring the machining accuracy.
[0019] (3) The present invention adopts a rigid connection between the rotating seat and the receiving seat, making its structure stable and firm. Because the rigid connection can provide very high strength and stability, and because there is almost no deformation at the connection, it can effectively transmit force and bending moment, so that the whole structure can withstand a large load.
[0020] In summary, this utility model has the advantages of good stability, high processing precision, high working efficiency, simple structure, and convenient assembly and disassembly. Attached Figure Description

[0028] Example
[0029] like Figure 1-4As shown, this embodiment provides a tilting device for a CNC thread grinding machine, including: a driving component 1, a tilting mechanism 2 disposed at the output end of the driving component 1, and a grinding mechanism 3 disposed on the tilting mechanism 2. A dividing turntable 21 for precisely controlling the rotation angle of the tilting mechanism 2 is disposed between the tilting mechanism 2 and the driving component 1. The dividing turntable 21 is provided with multiple numerical scales, which can quickly adjust the angle of the tilting mechanism 2, ensuring work efficiency, and making the grinding mechanism 3 more stable and accurate when processing tap threads, with small errors and high precision.
[0030] The swing mechanism 2 includes a rotating seat 22 rotatably connected to the driving member 1 and a receiving seat 23 disposed on the rotating seat 22. The rotating seat 22 drives the receiving seat 23 to rotate together to ensure the rotation of the grinding mechanism 3. The receiving seat 23 increases the force-bearing area of the grinding mechanism 3, thereby ensuring the stability and firmness of the grinding mechanism 3 during operation, making the thread processing more precise.
[0031] Meanwhile, the indexing turntable 21 is provided between the rotating seat 22 and the driving component 1, which has a compact structure and occupies little space.
[0032] In this embodiment, the indexing turntable 21 is fixedly connected to the rotating seat 22 and rotatably connected to the output end of the driving component 1. That is, the driving component 1 drives the indexing turntable 21 to rotate together. Its structure is simple and easy to use.
[0033] In this embodiment, the rotating seat 22 and the receiving seat 23 are rigidly connected. The rigid connection can provide very high strength and stability because there is almost no deformation at the connection point. It can effectively transmit force and bending moment, so that the whole structure can withstand a large load, making the structure stable and firm, thereby ensuring the service life of the swing mechanism 2.
[0034] In this embodiment, a spindle 24 is provided on the receiving seat 23, and the spindle 24 is connected to the grinding mechanism 3 to ensure the stability of the grinding mechanism 3.
[0035] Of course, the grinding mechanism 3 includes: a mounting base 31 rotatably connected to the spindle 24, a grinding wheel 32 mounted on the mounting base 31, and a dynamic balancing component 33 disposed close to the grinding wheel 32. The dynamic balancing component 33 mounted on the spindle 24 can reduce the vibration amplitude of the grinding wheel 32, thereby improving the stability of the grinding wheel 32 and ensuring the machining accuracy of the grinding wheel 32.
[0036] In addition, the dynamic balancing assembly 33 includes: a balancing head 331 disposed at one end of the grinding wheel 32 and a detector 332 disposed at the other end of the grinding wheel 32. The detector 332 is disposed on the spindle 24. The detector 332 is preferably a sensor that feeds back vibration signals to the balancing head 331 and automatically adjusts to stabilize the grinding wheel 32.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
