Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to an automated machine tool rigid spindle drive device. Background Technology

[0002] As the core power source of a machine tool, the rigid spindle drive unit plays a crucial role. It mainly consists of a spindle, a motor, and a transmission mechanism. The motor provides power, and the transmission mechanism transmits the power precisely. The two work together to drive the machine to operate stably and ensure that the machine tool can perform machining.

[0003] In existing technologies, a significant problem generally exists with machine tool spindle drive devices: their drive direction is usually set to a fixed state. This design makes the drive device inflexible and unsuitable when dealing with various instruments in different positions and with different processing requirements. Since the drive direction cannot be flexibly adjusted according to the actual processing scenario, machine tools often need to frequently change or adjust instrument positions when handling complex or diverse processing tasks. This not only increases the difficulty and cost of operation, but also affects processing efficiency and accuracy. To address this, we propose an automated machine tool rigid spindle drive device. Utility Model Content

[0004] One of the technical problems this application aims to solve is that it is not flexible and adaptable enough when dealing with various instruments in different positions and with different processing requirements.

[0005] To address the aforementioned technical problems, embodiments of this application provide an automated machine tool rigid spindle drive device, including a spindle and further comprising:

[0006] The motor is located on one side of the main shaft, and the drive end of the motor is fixedly connected to the main shaft. Mounting brackets are fixedly connected to both the top and bottom of the motor.

[0007] The transmission unit is located on one side of the main shaft. The transmission unit includes a first base plate and a second base plate. The second base plate rotates on top of the first base plate. The transmission unit also includes a rotating shaft, a rotating joint, and a cross shaft. The rotating shaft is connected to the main shaft and is used for transmission between the main shaft and the machine. It cooperates with the first base plate and the second base plate to adjust the driving direction.

[0008] In some embodiments, the transmission unit includes a first base plate disposed on one side of the main shaft, a second base plate rotatably connected to the top of the first base plate, a first vertical plate fixedly connected to the top of the first base plate, a second vertical plate disposed on the top of the second base plate, and a transmission component disposed within both the first and second vertical plates for connecting the main shaft for transmission.

[0009] In some embodiments, the transmission component includes a rotating shaft rotatably connected within a first vertical plate and a second vertical plate, one of the rotating shafts being engaged with a main shaft. A lubricating ring is fixedly connected to one side of both the first and second vertical plates. The rotating shaft passes through the lubricating ring and is fixedly connected to a rotating joint. Two rotating joints are provided, and a cross shaft is rotatably connected between the two rotating joints.

[0010] In some embodiments, the transmission components are configured as two sets, which are arranged opposite to each other, and a connecting shaft is fixedly connected between the two sets of rotating joints.

[0011] In some embodiments, a drive unit is provided on the top of the second base plate for driving the transmission unit to adjust the direction.

[0012] In some embodiments, the driving unit includes a semicircular plate fixedly connected to the outside of a first base plate, a semicircular groove formed in the semicircular plate, a limiting shaft fixedly connected to the bottom of a second base plate, the limiting shaft being slidably connected in the semicircular groove, a frame fixedly connected to the top of the second base plate, the frame being slidably connected to a second upright plate, a first hydraulic rod fixedly connected to the top of the frame, the driving end of the first hydraulic rod being fixedly connected to the top of the second upright plate, and a side drive component provided on the outside of the first base plate for lateral driving of the second base plate.

[0013] In some embodiments, the side drive component includes a support plate fixedly connected to the outside of the first base plate. Two support plates are provided, and the two support plates are disposed opposite to each other on both sides of the first base plate. A second hydraulic rod is rotatably connected to one side of each of the two support plates, and the driving ends of the two second hydraulic rods are rotatably connected to both sides of the frame respectively.

[0014] This utility model has at least the following beneficial effects:

[0015] By setting up a transmission unit, since both sets of rotating joints are rotatably connected by a cross shaft, the two rotating joints can rotate at multiple angles. One shaft is connected to the main shaft, and the other shaft, connected to the machine, rotates with the rotation of the second base plate, thereby adjusting the direction of the shafts and driving the machine at different positions.

[0016] By setting up a drive unit, the first hydraulic rod drives the second vertical plate to rise and fall, which in turn drives the rotating shaft connected to the machine to rise and fall, thereby driving the machine at different heights. The second hydraulic rods on both sides drive the second base plate to rotate, thereby adjusting the drive direction. In short, the drive direction can be adjusted to drive the machine at different positions. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A drive device for a rigid spindle 1 of an automated machine tool includes a spindle 1, a motor 2, and a transmission unit 4. The motor 2 is located on one side of the spindle 1, and its drive end is fixedly connected to the spindle 1. Mounting brackets 3 are fixedly connected to the top and bottom of the motor 2. The transmission unit 4 is located on one side of the spindle 1 and includes a first base plate 41 and a second base plate 42. The second base plate 42 rotates on top of the first base plate 41. The transmission unit 4 also includes a rotating shaft 451, a rotating joint 453, and a cross shaft 454. The rotating shaft 451 is connected to the spindle 1 and is used for transmission between the spindle 1 and the machine. It cooperates with the first base plate 41 and the second base plate 42 to adjust the driving direction.

[0026] The transmission unit 4 includes a first base plate 41 disposed on one side of the main shaft 1, a second base plate 42 rotatably connected to the top of the first base plate 41, a first upright plate 43 fixedly connected to the top of the first base plate 41, and a second upright plate 44 disposed on the top of the second base plate 42. The second upright plate 44 and the first upright plate 43 have different specifications to facilitate sliding of the frame 64.

[0027] Both the first vertical plate 43 and the second vertical plate 44 are provided with transmission components 45 for connecting the main shaft 1 for transmission. The transmission component 45 includes a rotating shaft 451 rotatably connected in the first vertical plate 43 and the second vertical plate 44. One rotating shaft 451 is engaged with the main shaft 1. A lubricating ring 452 is fixedly connected to one side of the first vertical plate 43 and the second vertical plate 44. The rotating shaft 451 passes through the lubricating ring 452 and is fixedly connected to a rotating joint 453. There are two rotating joints 453. A cross shaft 454 is rotatably connected between the two rotating joints 453. The transmission components 45 are configured in two sets, and the two sets of transmission components 45 are arranged opposite to each other. A connecting shaft 5 is fixedly connected between the two sets of rotating joints 453. The connecting shaft 5 is detachable and easy to replace.

[0028] In use, motor 2 is started first, which drives the main shaft 1 to rotate. The main shaft 1 is engaged with the rotating shaft 451, thereby driving the rotating shaft 451 to rotate. Then, the transmission is carried out through the transmission component 45. During this process, the second base plate 42 is rotated, which drives the second vertical plate 44 to rotate. Since the two sets of rotating joints 453 are rotatably connected by the cross shaft 454, the two rotating joints 453 can rotate at multiple angles. One rotating shaft 451 is connected to the main shaft 1, while the other rotating shaft 451 connected to the machine can rotate with the rotation of the second base plate 42 and the second vertical plate 44. In this way, the direction of the rotating shaft 451 can be adjusted, thereby driving the machine in different positions. Example 2

[0029] Please see Figure 4 This utility model provides a technical solution:

[0030] Unlike Embodiment 1, the top of the second base plate 42 is provided with a drive unit 6 for driving the transmission unit 4 to adjust the direction;

[0031] The drive unit 6 includes a semi-circular plate 61 fixedly connected to the outside of the first base plate 41, a semi-circular groove 62 formed in the semi-circular plate 61, a limiting shaft 63 fixedly connected to the bottom of the second base plate 42, the limiting shaft 63 being slidably connected in the semi-circular groove 62, a frame 64 fixedly connected to the top of the second base plate 42, the frame 64 being slidably connected to the second upright plate 44, a first hydraulic rod 65 fixedly connected to the top of the frame 64, the drive end of the first hydraulic rod 65 being fixedly connected to the top of the second upright plate 44, and a side drive member 66 provided on the outside of the first base plate 41 for lateral driving of the second base plate 42.

[0032] The side drive component 66 includes a support plate 661 fixedly connected to the outside of the first base plate 41. There are two support plates 661, which are arranged opposite to each other on both sides of the first base plate 41. A second hydraulic rod 662 is rotatably connected to one side of each of the two support plates 661. The driving ends of the two second hydraulic rods 662 are rotatably connected to both sides of the frame 64 respectively.

[0033] Activating the first hydraulic rod 65 drives the second vertical plate 44 to rise and fall, which in turn drives the rotating shaft 451 connected to the machine to rise and fall, thus enabling the machine to be driven at different heights. Activating the second hydraulic rods 662 on both sides can drive the second base plate 42 to rotate through the limiting shaft 63 and the semi-circular groove 62, thereby adjusting the driving direction.
