Description

Technical Field

[0001] The utility model relates to the technical field of iron core surface treatment, and particularly relates to a CVD water table lifting and rotating device. Background Technique

[0002] CVD refers to a gas-phase reaction at high temperature. This technology was initially developed as a means of coating, but it is not only applied to the coating of heat-resistant substances, but also to the refining of high-purity metals, powder synthesis, semiconductor thin films, etc. When processing the high-temperature resistant protective coating of the iron core, a CVD water table lifting and rotating device is required.

[0003] For example, the utility model with the application number CN201922489401.9 discloses a CVD water table lifting and rotating device. When the motor drives the screw rod to rotate, the T-shaped nut can move up and down along the screw rod, and then drive the entire lifting frame to move up and down along the screw rod, so as to drive the CVD water table to lift. When the rotating device rotates, it drives the installation shaft to rotate, thereby driving the CVD water table installed on the installation shaft to rotate. This utility model has a simple structure and is easy to process. However, during the use of this type of equipment, multiple power sources need to be used to drive separately, resulting in the problem of increasing the overall cost of the equipment.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a CVD water table lifting and rotating device is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a CVD water table lifting and rotating device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A CVD water table lifting and rotating device, including a fixed frame and a driving component. A screw sleeve is fixed in the center of the top of the fixed frame, and a screw rod is threadedly connected inside the screw sleeve. The top of the screw rod is rotatably connected to a lifting frame, and guide rods are arranged at both ends of the bottom of the lifting frame. The center of the top of the lifting frame is rotatably connected to an output shaft. The driving component is arranged inside the lifting frame. The driving component includes a motor, a driving shaft, sliders, sliding sleeves, driving gears, adjusting plates, limiting sliding seats, return springs, iron blocks, electromagnets, a first driven gear, and a second driven gear. The bottom of the motor is connected to the driving shaft, and the sliders are slidably connected to both sides of the driving shaft. A sliding sleeve is fixed to one side of the slider, and a driving gear is fixed to the bottom of the sliding sleeve. The outside of the sliding sleeve is rotatably connected to the adjusting plate, and the limiting sliding seat is slidably connected inside one end of the adjusting plate. A return spring is connected to the top of one end of the adjusting plate, and iron blocks are fixed to both sides of the adjusting plate. The first driven gear is arranged at the top of the screw rod, and the second driven gear is fixed to the bottom of the output shaft.

[0007] Further, two guiding rods are symmetrically arranged with respect to the center line of the lifting frame, and the guiding rods are slidably connected to the fixed frame.

[0008] Further, the limit sliding seat is fixedly connected to the lifting frame, and the motor is also fixedly connected to the lifting frame.

[0009] Further, a stabilizing assembly is arranged inside the lifting frame. The stabilizing assembly includes a bracket and a sliding rod. The bracket is fixed inside the lifting frame, and the sliding rod is slidably connected to the upper end inside the bracket.

[0010] Further, the stabilizing assembly further includes a positioning spring and a positioning plate. The positioning spring is sleeved on the outer side of the upper end of the sliding rod, and the bottom of the positioning spring is connected to the positioning plate.

[0011] Further, the positioning plate is arc-shaped and is fixedly connected to the sliding rod.

[0012] Further, the stabilizing assembly further includes a rubber pad and a top rod. The rubber pad is arranged at the bottom of the positioning plate, and the top rod is fixed to one side of the positioning plate.

[0013] Further, the adjusting plate is slidably connected to the driving shaft and is in contact with the top rod.

[0014] The utility model provides a CVD water table lifting and rotating device, which has the following beneficial effects:

[0015] 1. Through the setting of the driving assembly in the utility model, when it is necessary to adjust the height of the water table at the end of the output shaft, only the power supply of the electromagnet needs to be disconnected. At this time, the reset spring can push the adjusting plate, so that the sliding sleeve drives the driving gear to mesh with the first driven gear. At this time, the motor can drive the sliding sleeve to rotate through the driving shaft and the slider, and then drive the screw rod to rotate through the driving gear and the first driven gear, so that the lifting frame can move up and down under the limit of the guiding rod, so as to control the height of the water table according to the needs. And during the coating process, when it is necessary to rotate the water table, only the power supply of the electromagnet needs to be connected. At this time, the electromagnet will adsorb the iron block, thereby driving the adjusting plate to move up along the limit sliding seat, so that the adjusting plate drives the driving gear at the lower end of the sliding sleeve to mesh with the second driven gear. At this time, the motor can control the rotation of the output shaft, thereby driving the water table to rotate, which can make full use of the motor and is beneficial to saving the overall cost;

[0016] 2. Through the setting of the stabilizing assembly in the utility model, during the meshing process of the driving gear and the first driven gear, the positioning spring will push the positioning plate, so that the rubber pad is in close contact with the tooth part of the second driven gear, thereby using the large friction force of the rubber pad to reduce the shaking of the second driven gear. And when the driving gear meshes with the second driven gear, the adjusting plate can push the positioning plate through the top rod, so that the rubber pad is separated from the second driven gear, avoiding interfering with the rotation of the second driven gear.

Detailed Description of the Preferred Embodiment

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figures 1 to 3As shown in the figure, a CVD water table lifting and rotating device includes a fixed frame 1 and a driving assembly 7. A screw sleeve 2 is fixedly installed at the center of the top of the fixed frame 1, and a screw rod 3 is threadedly connected inside the screw sleeve 2. The top of the screw rod 3 is rotatably connected to a lifting frame 4. At both ends of the bottom of the lifting frame 4, there are guide rods 5. Two guide rods 5 are symmetrically arranged about the center line of the lifting frame 4, and the guide rods 5 are slidably connected to the fixed frame 1. The guide rods 5 can limit and guide the lifting frame 4. The center of the top of the lifting frame 4 is rotatably connected to an output shaft 6. The driving assembly 7 is arranged inside the lifting frame 4. The driving assembly 7 includes a motor 701, a driving shaft 702, a slider 703, a sliding sleeve 704, a driving gear 705, an adjusting plate 706, a limiting sliding seat 707, a return spring 708, an iron block 709, an electromagnet 710, a first driven gear 711, and a second driven gear 712. The bottom of the motor 701 is connected to the driving shaft 702. On both sides of the driving shaft 702, there are sliders 703 slidably connected. One side of the slider 703 is fixed with a sliding sleeve 704, and the bottom of the sliding sleeve 704 is fixed with a driving gear 705. At this time, the motor 701 can drive the driving gear 705 at the bottom of the sliding sleeve 704 to rotate through the driving shaft 702 and the slider 703. The outside of the sliding sleeve 704 is rotatably connected to an adjusting plate 706. Inside one end of the adjusting plate 706, there is a limiting sliding seat 707 slidably connected. The limiting sliding seat 707 is fixedly connected to the lifting frame 4, and the motor 701 is also fixedly connected to the lifting frame 4. The limiting sliding seat 707 can limit and support the adjusting plate 706. The top of one end of the adjusting plate 706 is connected to a return spring 708, and iron blocks 709 are fixed on both sides of the adjusting plate 706. At the top of the screw rod 3, there is a first driven gear 711. When the power supply of the electromagnet 710 is disconnected, the return spring 708 can push the adjusting plate 706, so that the sliding sleeve 704 drives the driving gear 705 to mesh with the first driven gear 711. When the first driven gear 711 drives the screw rod 3 to rotate, the lifting frame 4 can move up and down under the limitation of the guide rods 5, so as to control the height of the water table according to requirements. At the bottom of the output shaft 6, there is a second driven gear 712. When the adjusting plate 706 drives the driving gear 705 to mesh with the second driven gear 712, at this time, the motor 701 can control the rotation of the output shaft 6, thereby driving the water table to rotate.

[0023] As Figure 2As shown in the figure, a stabilizing component 8 is arranged inside the lifting frame 4. The stabilizing component 8 includes a bracket 801 and a sliding rod 802. The bracket 801 is fixed inside the lifting frame 4, and the sliding rod 802 is slidably connected to the upper end inside the bracket 801. The stabilizing component 8 further includes a positioning spring 803 and a positioning plate 804. The positioning spring 803 is sleeved on the outer side of the upper end of the sliding rod 802, and the bottom of the positioning spring 803 is connected to the positioning plate 804. The positioning plate 804 is arc-shaped and is fixedly connected to the sliding rod 802. The positioning spring 803 will push the positioning plate 804 under the limitation of the bracket 801 and the sliding rod 802. The stabilizing component 8 further includes a rubber pad 805 and a push rod 806. The rubber pad 805 is arranged at the bottom of the positioning plate 804, and a push rod 806 is fixed on one side of the positioning plate 804. When the rubber pad 805 is in close contact with the tooth part of the second driven gear 712, the large friction force of the rubber pad 805 can be utilized to reduce the shaking of the second driven gear 712. The adjusting plate 706 is slidably connected to the driving shaft 702 and is in contact with the push rod 806. When the adjusting plate 706 rises, the adjusting plate 706 can also push the positioning plate 804 through the push rod 806, so that the rubber pad 805 is separated from the second driven gear 712, avoiding interfering with the rotation of the second driven gear 712.

[0024] In summary, when the CVD water table lifting and rotating device is used, first, according to Figure 1 , Figure 2 and Figure 3 the structure shown in the figure, first disconnect the power supply of the electromagnet 710. At this time, the reset spring 708 can push the adjusting plate 706, so that the sliding sleeve 704 drives the driving gear 705 to mesh with the first driven gear 711. At the same time, the positioning spring 803 will push the positioning plate 804 under the limitation of the bracket 801 and the sliding rod 802, so that the rubber pad 805 is in close contact with the tooth part of the second driven gear 712. Then, the motor 701 can drive the sliding sleeve 704 to rotate through the driving shaft 702 and the slider 703, so as to drive the screw rod 3 to rotate through the driving gear 705 and the first driven gear 711. At the same time, the screw sleeve 2 is fixed on the fixed frame 1, and the lifting frame 4 can move up and down under the limitation of the guide rod 5, so as to control the height of the water table at the end of the output shaft 6 according to the needs. Finally, during the process of coating the iron core, when the water table needs to be rotated, just connect the power supply of the electromagnet 710. At this time, the electromagnet 710 will adsorb the iron block 709, thereby driving the adjusting plate 706 to move up along the limit sliding seat 707, so that the adjusting plate 706 drives the driving gear 705 at the lower end of the sliding sleeve 704 to mesh with the second driven gear 712. At the same time, the adjusting plate 706 can also push the positioning plate 804 through the push rod 806, so that the rubber pad 805 is separated from the second driven gear 712. At this time, the motor 701 can control the rotation of the output shaft 6, thereby driving the water table to rotate, improving the uniformity during the coating process.
