Description

Technical Field

[0001] This utility model belongs to the field of bearing support technology, specifically relating to a precision bearing support device for a high-precision, high-torque turntable. Background Technology

[0002] The precision bearing support device for a high-precision, high-torque rotary table is a key component used to support and position the rotary table spindle. It plays a crucial role in fields requiring high precision and high torque, such as aerospace, precision machine tools, and robotics. This device, through high-precision bearings and a support structure, ensures the stable operation of the rotary table spindle under high torque and precision requirements. It must not only withstand large radial and axial loads but also guarantee the rotary table's rotational accuracy and rigidity, thereby ensuring the stability and reliability of the entire system.

[0003] However, existing precision bearing support devices have some shortcomings in practical applications. On the one hand, existing support devices usually adopt a fixed support structure, which cannot be flexibly adjusted according to the actual position and load of the spindle. This leads to the need to spend a lot of time and effort on precise alignment and adjustment during installation and maintenance, increasing the complexity and cost of operation. On the other hand, existing support devices have limitations in improving the spindle rotation accuracy and stability. Due to insufficient rigidity or unreasonable design of the support structure, the spindle is prone to vibration and displacement under high torque and high speed conditions, which affects the machining accuracy and service life of the turntable. Therefore, an improved solution is needed that can flexibly adjust the support position and effectively improve the spindle rotation accuracy and stability. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up a support structure adjustment mechanism, can realize flexible adjustment of the support position. The operation of motor one drives the drive shaft to rotate, which in turn drives bevel gear one to rotate bevel gear two, thereby driving the threaded rod to rotate, so that the telescopic rod moves along the threaded rod, realizing the change of the support position of the support device to adapt to the main shaft bearing support requirements of different positions, improving the versatility and applicability of the device, reducing the time and effort of centering adjustment during installation and maintenance, and reducing the complexity and cost of operation.

[0014] 2. This utility model, by setting up a spindle bearing support mechanism, can achieve precise positioning and stable support of the spindle bearing. The second motor drives the bidirectional lead screw to rotate, causing the two sets of slides to move inward or outward simultaneously along the bidirectional lead screw, thereby moving the arc plate closer to or away from the spindle bearing, realizing the clamping or loosening of the spindle bearing.

[0019] 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.

[0020] Example 1

[0021] Please see Figure 1-3 The present invention provides the following technical solution: a precision bearing support device for a high-precision, high-torque turntable, comprising a support device body 1, a control panel 6 provided at the lower side of the support device body 1, a worktable 2 provided at the center of the side of the support device body 1, a support structure adjustment mechanism 5 provided on the side of the worktable 2, a mounting plate 3 provided at the other end of the support structure adjustment mechanism 5, and a main shaft bearing support mechanism 4 provided on the side of the mounting plate 3.

[0022] Specifically, the support structure adjustment mechanism 5 includes a drive shaft 51, a second bevel gear 52, a column 53, a telescopic rod 55, a first bevel gear 57, a first motor 58, and a threaded rod 59. A column 53 is located on the side of the worktable 2. A threaded rod 59 is rotatably connected inside the column 53. A telescopic rod 55 is threaded to the other end of the threaded rod 59. A first motor 58 is located on the side of the column 53. A drive shaft 51 is located at the output end of the first motor 58. A first bevel gear 57 is located at the other end of the drive shaft 51. A second bevel gear 52, which meshes with the first bevel gear 57, is located on the surface of the threaded rod 59.

[0023] By adopting the above technical solution, the support position can be flexibly adjusted. The operation of motor 58 drives the drive shaft 51 to rotate, which in turn causes bevel gear 57 to drive bevel gear 52 to rotate, thereby driving the threaded rod 59 to rotate, so that the telescopic rod 55 moves along the threaded rod 59, realizing the change of the support position of the support device to adapt to the main shaft bearing support requirements of different positions, thus improving the versatility and applicability of the device.

[0024] Specifically, the support structure adjustment mechanism 5 also includes a slide groove 54 and a slider 56. The inner wall of the column 53 is provided with a slider 56, and the side of the telescopic rod 55 is provided with a slide groove 54 corresponding to the slider 56.

[0025] By adopting the above technical solution, the stable movement of the telescopic rod 55 can be guaranteed. The slider 56 is embedded in the slide groove 54, which guides and limits the movement of the telescopic rod 55, preventing the telescopic rod 55 from deviating or shaking during the movement, and ensuring the accuracy and stability of the support position adjustment.

[0026] Specifically, one end of the threaded rod 59 is rotatably connected to the column 53 via a bearing, and the telescopic rod 55 has a threaded groove inside that corresponds to the threaded rod 59.

[0027] By adopting the above technical solution, the rotational resistance of the threaded rod 59 can be reduced, the transmission efficiency and service life of the device can be improved, the bearing setting allows the threaded rod 59 to rotate smoothly in the column 53, and the threaded groove in the telescopic rod 55 is precisely matched with the threaded rod 59, ensuring the smooth movement of the telescopic rod 55 and accurate support position adjustment.

[0028] In this embodiment, the motor 58 is started first through the control panel 6 according to the position of the spindle bearing, so that the telescopic rod 55 is moved to the appropriate position. Then, the spindle bearing is installed on the spindle bearing support mechanism 4. By adjusting the support structure adjustment mechanism 5, the spindle bearing is stably supported, thereby ensuring the normal operation and high-precision work of the torque turntable.

[0029] Example 2

[0030] The difference between this embodiment and Embodiment 1 is that the spindle bearing support mechanism 4 includes a slide 44, a double-acting lead screw 45, a second motor 46, and an arc-shaped plate 49. The second motor 46 is provided at the upper end of the mounting plate 3, and the double-acting lead screw 45 is provided at the output end of the second motor 46. Two sets of slides 44 are threaded to both ends of the double-acting lead screw 45. The slides 44 have corresponding threaded holes inside, and the arc-shaped plate 49 is provided on the side of the slides 44.

[0031] By adopting the above technical solution, the spindle bearing can be accurately positioned and stably supported. The motor 46 drives the bidirectional lead screw 45 to rotate, causing the two sets of slides 44 to move inward or outward along the bidirectional lead screw 45 at the same time. This, in turn, causes the arc plate 49 to move closer to or away from the spindle bearing, thereby clamping or releasing the spindle bearing. This accurately positions and supports the spindle bearing, improving the accuracy and stability of the spindle rotation.

[0032] Specifically, the spindle bearing support mechanism 4 also includes a slide rail 47 and a pulley 48. The pulley 48 is provided inside the side of the slide block 44, and the slide rail 47 corresponding to the pulley 48 is provided on the inner wall of the mounting plate 3.

[0033] By adopting the above technical solution, the smooth movement of the slide block 44 can be ensured. The pulley 48 rolls in the slide rail 47, which guides and supports the movement of the slide block 44, reduces the friction between the slide block 44 and the mounting plate 3, and enables the slide block 44 to move smoothly and steadily, further improving the stability of the spindle bearing support.

[0034] Specifically, the main shaft bearing support mechanism 4 also includes an arc-shaped groove 41, rollers 42, and pins 43. The arc-shaped plate 49 has an arc-shaped groove 41 on its side, and multiple sets of rollers 42 are arranged inside the arc-shaped groove 41. The rollers 42 are rotatably connected to the arc-shaped plate 49 through pins 43.

[0035] By adopting the above technical solution, the contact between the arc plate 49 and the main shaft bearing can be made more closely and evenly. The multiple sets of rollers 42 can rotate in the arc groove 41, which can adapt to the shape of the main shaft bearing, increase the contact area with the main shaft bearing, improve the stability and reliability of the support, reduce local stress concentration, and extend the service life of the main shaft bearing.

[0036] In this embodiment, the motor 46 is started via the control panel 6, causing the bidirectional lead screw 45 to rotate and move the slide 44, thereby bringing the arc plate 49 closer to the main shaft bearing. Once the arc plate 49 contacts the main shaft bearing, the slide 44 continues to move, causing the roller shaft 42 on the arc plate 49 to press against the main shaft bearing, thus achieving stable support for the main shaft bearing. During the rotation of the main shaft, the roller shaft 42 on the arc plate 49 can roll along with the rotation of the main shaft bearing, reducing friction and ensuring smooth rotation of the main shaft, thereby improving the accuracy and stability of the torque turntable.

[0037] The working principle and usage process of this utility model are as follows: First, based on the position of the main spindle bearing, the motor 58 is started via the control panel 6, causing the telescopic rod 55 to move to a suitable position. Then, the main spindle bearing is installed on the main spindle bearing support mechanism 4. By adjusting the support structure adjustment mechanism 5, the main spindle bearing receives stable support, thus ensuring the normal operation and high-precision work of the torque turntable. Next, the motor 46 is started via the control panel 6, causing the bidirectional lead screw 45 to rotate, driving the slide 44 to move, thereby bringing the arc plate 49 closer to the main spindle bearing. Once the arc plate 49 contacts the main spindle bearing, the slide 44 continues to move, causing the roller shaft 42 on the arc plate 49 to press against the main spindle bearing, achieving stable support for the main spindle bearing. During the rotation of the main spindle, the roller shaft 42 on the arc plate 49 can roll along with the rotation of the main spindle bearing, reducing friction and ensuring smooth rotation of the main spindle, thus improving the accuracy and stability of the torque turntable.
