Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and in particular to an angle adjustment device for a machine tool spindle. Background Technology

[0002] With the continuous development of the manufacturing industry, the requirements for the precision and flexibility of machine tool processing are becoming increasingly stringent. In the machining process, many complex parts require machine tool spindles to perform cutting, drilling, and other operations at different angles to meet the specific shape and precision requirements of the parts. For example, some components in the aerospace field have complex curved surfaces and tilt angles, requiring the spindle to be able to precisely adjust its angle for machining.

[0003] In existing technologies, some devices have low angle adjustment accuracy, making it difficult to meet the demands of high-precision machining. Their adjustment methods are often inflexible, potentially only allowing for a limited number of fixed angle adjustments, and unable to provide continuous and precise angle changes based on actual machining conditions. Furthermore, traditional devices are complex to operate during adjustment, requiring significant time and manpower, thus reducing production efficiency. In terms of stability after spindle angle adjustment, traditional devices perform poorly. During machine tool processing, external forces such as vibration and cutting forces can easily cause the adjusted spindle angle to deviate, affecting machining accuracy and part quality, necessitating improvements. Utility Model Content

[0004] This utility model mainly provides a machine tool spindle angle adjustment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a machine tool spindle angle adjustment device, comprising a base, a spindle box on the surface of the base, a spindle body inside the spindle box, a drive motor A on the side of the spindle box, an adjustment disc rotatably connected inside the base, a rotating shaft rotatably connected inside the base, a worm gear fixedly mounted on the surface of the rotating shaft, a worm gear rotatably connected inside the base, a drive motor B fixedly mounted on the side of the base, a scale plate fixedly mounted on the surface of the base, a scale pointer on the lower surface of the spindle box, an oil inlet on the side of the base, an oil outlet on the lower surface of the base, a connecting rod slidably connected inside the base, a base block fixedly mounted at one end of the connecting rod, a limit plate fixedly mounted at the other end of the connecting rod, a tension spring fixedly connected to the inner side of the base, and a damper fixedly mounted inside the base.

[0006] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0007] 1. In this utility model, the worm gear is driven to rotate by the drive motor B. Due to the meshing transmission between the worm wheel and the worm, the adjustment disc fixed on the same shaft as the worm wheel rotates, thereby accurately driving the spindle body to adjust its angle. The scale plate and scale pointer work together to allow the operator to intuitively know the changes in the spindle angle, which facilitates precise control of the spindle angle to meet different processing needs. When the spindle box and spindle body tend to deviate in angle due to external force, the tension spring can provide a certain reverse pulling force, and the damper can consume vibration energy. The two work together to effectively reduce the deviation of the spindle angle, ensure the angular stability of the spindle during the processing, and improve the processing accuracy.

[0008] 2. In this utility model, by starting the drive motor C, its output end drives the bidirectional lead screw to rotate, and the connecting block threaded to the bidirectional lead screw slides on the mounting plate, thereby driving the connecting plate and the limiting rod to move, so that the limiting rod is inserted into the limiting hole of the adjusting plate, thereby locking the adjusting plate and preventing the spindle angle from changing unexpectedly during processing.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Please see Figures 1-4 This utility model provides a technical solution: a machine tool spindle angle adjustment device, including a base 1, a spindle box 2 on the surface of the base 1, a spindle body 3 inside the spindle box 2, a drive motor A4 on the side of the spindle box 2, an adjustment plate 5 rotatably connected inside the base 1, a rotating shaft 6 rotatably connected inside the base 1, a worm gear 7 fixedly installed on the surface of the rotating shaft 6, a worm 8 rotatably connected inside the base 1, a drive motor B9 fixedly installed on the side of the base 1, a scale plate 10 fixedly installed on the surface of the base 1, a scale pointer 11 on the lower surface of the spindle box 2, an oil inlet 12 on the side of the base 1, an oil outlet 13 on the lower surface of the base 1, a connecting rod 14 slidably connected inside the base 1, a base block 15 fixedly installed at one end of the connecting rod 14, a limit plate 16 fixedly installed at the other end of the connecting rod 14, a tension spring 17 fixedly connected to the inner side of the base 1, and a damper 18 fixedly installed inside the base 1.

[0016] like Figure 2 As shown, the upper surface of the adjusting disk 5 is fixedly connected to the lower surface of the spindle box 2, and one end of the rotating shaft 6 is fixedly connected to the lower surface of the adjusting disk 5. Here, by rotating the rotating shaft 6, the spindle box 2 can accurately rotate synchronously with the adjusting disk 5, thereby achieving effective adjustment of the angle of the spindle body 3.

[0017] like Figure 2 As shown, the worm gear 7 and the worm 8 mesh and drive each other. The output end of the drive motor B9 is fixedly connected to one end of the worm 8. Here, the adjusting disc 5 and the rotating shaft 6 can rotate through the meshing transmission between the worm gear 7 and the worm 8.

[0018] like Figure 2 As shown, the other end of the tension spring 17 is fixedly connected to the side of the limiting plate 16, and the limiting plate 16 is slidably connected to the base 1. Here, through the elastic action of the tension spring 17, when the machine tool vibrates or is subjected to external force impact during operation, the tension spring 17 can absorb and buffer energy, reducing the impact on the spindle box 2 and the spindle body 3.

[0019] like Figure 2 As shown, a mounting plate 19 is fixedly mounted on the surface of the base 1. A connecting plate 20 is slidably connected to the side of the mounting plate 19. A limit rod 21 is fixedly mounted on the side of the connecting plate 20. A limit hole 22 is opened on the surface of the adjusting plate 5. A connecting block 23 is fixedly connected to one end of the connecting plate 20. A bidirectional lead screw 24 is rotatably connected inside the mounting plate 19. A drive motor C25 is fixedly mounted on the side of the mounting plate 19. Here, by starting the drive motor C25, its output end drives the bidirectional lead screw 24 to rotate, so that the limit rod 21 is inserted into the limit hole 22 of the adjusting plate 5, thereby locking the adjusting plate 5 and preventing the spindle angle from changing unexpectedly during processing.

[0020] like Figure 2 As shown, the output end of the drive motor C25 is fixedly connected to one end of the bidirectional lead screw 24. The bidirectional lead screw 24 is threadedly connected to the connecting block 23. Here, the drive motor C25 causes the bidirectional lead screw 24 to rotate. The threaded connection between the bidirectional lead screw 24 and the connecting block 23 allows the connecting block 23 to move in opposite directions.

[0021] like Figure 2 As shown, the limiting rod 21 is slidably connected to the limiting hole 22, and the connecting block 23 is slidably connected to the mounting plate 19. Here, the sliding connection between the limiting rod 21 and the limiting hole 22 ensures that the limiting rod 21 can be inserted into and withdrawn from the limiting hole 22 smoothly and without obstruction, and can fit tightly after being inserted into the limiting hole 22, effectively limiting the rotation of the adjusting plate 5.

[0022] The usage and working principle of this device are as follows: When using this machine tool spindle angle adjustment device, first determine the required angle of the spindle body 3 according to the processing requirements. To adjust the angle, start the drive motor B9, whose output end drives the worm 8 to rotate. Since the worm wheel 7 and the worm 8 are in a meshing transmission state, the rotation of the worm 8 drives the worm wheel 7 to rotate. The worm wheel 7 is fixed on the rotating shaft 6, which is connected to the adjusting plate 5. Therefore, the rotating shaft 6 drives the adjusting plate 5 to rotate synchronously. Since the upper surface of the adjusting plate 5 is fixedly connected to the lower surface of the spindle box 2, the angle of the spindle box 2 and the internal spindle body 3 is finally adjusted. During the adjustment process, the operator can observe the real-time changes of the spindle angle by observing the scale plate 10 and the scale pointer 11, thereby accurately controlling the operation of the drive motor B9 to make the spindle body 3 reach the desired angle. After the angle adjustment is completed, start the drive motor C25 to drive the bidirectional lead screw 24 to rotate. Since the bidirectional lead screw 24 and the connecting block 23 are connected by threads, the connecting block 23 is mounted on the mounting plate. When the connecting block 23 slides up, it will drive the connecting plate 20 to move. The limiting rod 21 fixed on the side of the connecting plate 20 will also move until the limiting rod 21 is inserted into the limiting hole 22 on the surface of the adjusting plate 5, successfully locking the adjusting plate 5. This prevents the spindle angle from changing unexpectedly due to external forces during subsequent processing. During the operation of the machine tool, when the spindle box 2 and the spindle body 3 have an angular deviation tendency due to external forces such as cutting force, the tension spring 17, which is fixedly connected to the side of the limiting plate 16 and connected to the inner side of the base 1 at the other end, plays a role in providing a reverse pull force. At the same time, the damper 18 fixedly installed inside the base 1 consumes vibration energy. The two work together to reduce the deviation of the spindle angle and ensure that the spindle always maintains a stable angle during processing. In addition, during long-term use of the device, lubricating oil can be injected through the oil inlet 12 on the side of the base 1. The lubricating oil flows inside the device, lubricates the worm gear 7 and worm 8, and then flows out from the oil outlet 13 on the lower surface of the base 1, ensuring smooth operation of all components of the device and extending the service life of the device.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
