Description

Technical Field

[0001] This utility model relates to the field of material cart transmission for vacuum furnaces, specifically a material cart transmission clamping interlocking mechanism. Background Technology

[0002] In the transmission and operation of a vacuum chamber and a material cart, the material cart needs to obtain power through a swing gear structure inside the vacuum chamber to move in and out of the vacuum chamber. In the existing technology, the swing gear structure inside the vacuum chamber directly meshes with the rollers of the material cart for transmission. However, during the process of the material cart moving out of the vacuum chamber, the gear is subjected to the reaction force of the rollers. Due to the lack of an effective limiting and locking mechanism, the gear is easily lifted up under the action of this reaction force, causing the gear to disengage from the rollers. This results in the material cart losing continuous transmission power and thus failing to discharge material normally. At the same time, when the material cart enters the vacuum chamber, the gear swing arm needs to have a certain degree of swing flexibility to avoid the gear teeth from jamming with the rollers. However, the existing structure cannot balance the flexibility of gear meshing with the stability during the transmission process, resulting in insufficient transmission reliability. This affects the smoothness of the material cart entering and leaving the vacuum chamber and the working efficiency, and cannot meet the needs of continuous production. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a material cart transmission pressing interlocking mechanism.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a material cart transmission pressing interlocking mechanism, including a vacuum chamber swing gear structure set on the inner wall of the vacuum chamber, a fixed seat fixed on the inner wall of the vacuum chamber near the vacuum chamber swing gear structure, a rotating shaft fixing member set at the bottom of the inner wall of the fixed seat, a rotating shaft fixed inside the rotating shaft fixing member, and a pendulum for supporting the vacuum chamber swing gear structure fixed on the outer wall of the rotating shaft.

[0005] Furthermore, the vacuum chamber swing gear structure includes a gear swing arm rotatably connected to the inner wall of the vacuum chamber via a rotating shaft. The side wall of the gear swing arm contacts one end of the pendulum. A gear set is rotatably connected inside the gear swing arm. The gear set is composed of a driving gear and a driven gear. The driving gear is connected to a power unit. A material cart roller meshes below the driven gear. A swing arm limiting member is attached to the bottom side wall of the gear swing arm. The swing arm limiting member is fixedly connected to the inner wall of the vacuum chamber.

[0006] Furthermore, the rotating shaft fixing component includes a rotating shaft bracket fixed to the bottom of the inner wall of the fixing seat. A rotating shaft cover for fixing the rotating shaft is fastened to the rotating shaft bracket. A cover fastener is threadedly connected to the inside of the rotating shaft cover. The cover fastener passes through the rotating shaft cover and the rotating shaft through hole and is threadedly connected to the rotating shaft bracket.

[0007] Furthermore, one end of the pendulum that contacts the side wall of the gear swing arm is provided with an inclined surface for fitting against the side wall of the gear swing arm, and the other end of the pendulum is provided with a trapezoidal block.

[0008] The beneficial effects of this utility model are: This invention solves the problem in existing technologies where the gears easily lift and detach from the rollers when the material cart exits the vacuum chamber. By interlocking the pendulum with the gear swing arm, the gear swing arm is locked and fixed after the material cart is fully engaged, ensuring that the gear set and the material cart rollers are continuously and fully engaged, guaranteeing uninterrupted power transmission and improving material discharge stability.

[0009] It takes into account both the smooth meshing when the material car enters and the structural stability during the transmission process. In the initial stage of the material car entering, the pendulum does not apply a clamping force, and the gear swing arm can swing freely to avoid the gear teeth tip from jamming with the roller of the material car. After meshing, the pendulum locks the gear swing arm, achieving the dual effect of "flexible meshing and stable transmission".

[0010] The coordinated operation of all components, including the fixed base and shaft fixing parts (shaft bracket, shaft cover, cover fastener), ensures the installation stability and motion reliability of the pendulum and shaft. The swing arm limiting parts further optimize the motion trajectory of the gear swing arm, thereby improving the overall transmission accuracy and service life of the mechanism.

[0011] The structure is simple and compact, requiring no major modifications to the main structure of existing vacuum chambers and material carts. It is easy to install and maintain, has a wide range of applications, and can effectively adapt to various transmission scenarios of vacuum chambers and material carts, reducing production modification costs.

[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0018] See Figures 1-4 This is a schematic diagram of the structure of this utility model, a material cart transmission pressing interlocking mechanism, including a vacuum chamber swing gear structure set on the inner wall of the vacuum chamber. A fixed seat 5 is fixed on the inner wall of the vacuum chamber near the swing gear structure. The fixed seat 5 serves as the mounting base for the entire interlocking mechanism, providing a stable support for subsequent components such as the rotating shaft fixing component, rotating shaft 7, and pendulum 10, ensuring the position of each component during operation and preventing loosening. A rotating shaft fixing component is provided at the bottom of the inner wall of the fixed seat 5. The rotating shaft fixing component is specifically used to limit and fix the rotating shaft 7, preventing axial displacement or radial wobbling of the rotating shaft 7 during rotation, and ensuring the stability of the rotating shaft 7. To ensure smooth and stable rotation, a rotating shaft 7 is fixed inside the rotating shaft fixing component. The rotating shaft 7 serves as the mounting carrier for the pendulum 10 and provides a rotation center for the swing of the pendulum 10, allowing the pendulum 10 to rotate flexibly around it. The rotating shaft 7 must have sufficient strength and wear resistance to withstand the force generated when the pendulum 10 swings. The outer wall of the rotating shaft 7 is fixed with the pendulum 10, which supports the swing gear structure of the vacuum chamber. The pendulum 10 is a component that realizes the interlocking function. It uses its own swing to tighten or release the gear swing arm 2, thereby controlling the activity state of the gear swing arm 2 and ensuring stable meshing between the gear set 3 and the material carriage roller 1.

[0019] The vacuum chamber oscillating gear structure includes a gear swing arm 2 rotatably connected to the inner wall of the vacuum chamber via a rotating shaft. The gear swing arm 2 provides mounting support for the gear set 3 and can flexibly swing around its own rotating shaft to adjust the angle when the material cart roller 1 enters, preventing the gear teeth from jamming with the roller. The side wall of the gear swing arm 2 contacts one end of the pendulum 10. Through close contact with the pendulum 10, it receives the limiting force transmitted by the pendulum, realizing the switching of its own oscillation state. The gear set 3 is rotatably connected inside the gear swing arm 2. The gear set 3 is composed of a drive gear and a driven gear. The power unit is connected to receive the driving force transmitted by the power unit and transmit the power to the driven gear. The driven gear meshes with the material cart roller 1 below. Through the meshing transmission with the material cart roller 1, the power is transmitted to the material cart, which drives the material cart to move in and out of the vacuum chamber. The bottom side wall of the gear swing arm 2 is attached to the swing arm limiting member 4. The swing arm limiting member 4 is fixedly connected to the inner wall of the vacuum chamber. The swing arm limiting member 4 is used to limit the lowest swing position of the gear swing arm 2, so as to avoid the gear swing arm 2 from affecting the normal meshing with the material cart roller due to excessive swinging, and at the same time, it provides a stable contact support point for the gear swing arm 2.

[0020] The rotating shaft fixing component includes a rotating shaft bracket 6 fixed to the bottom of the inner wall of the fixing base 5. The rotating shaft bracket 6 is used to support the rotating shaft 7. Its top is designed as a support structure adapted to the rotating shaft 7, providing stable bottom support for the rotating shaft 7. The rotating shaft 7 is a stepped solid shaft. A rotating shaft cover 8 for fixing the rotating shaft 7 is fastened to the rotating shaft bracket 6. The rotating shaft cover 8 and the rotating shaft bracket 6 cooperate to form a closed fixing space, pressing and limiting the rotating shaft 7 from the top to prevent the rotating shaft 7 from moving up and down. The rotating shaft cover 8 has a cover fastener 9 connected to its internal thread. The cover fastener 9, together with the rotating shaft cover 8 and the rotating shaft bracket 6, is used to fix the rotating shaft 7. Through the threaded fastening action, the rotating shaft cover 8, the rotating shaft 7 and the rotating shaft bracket are firmly fixed as one, ensuring the reliability of the rotating shaft fixing and avoiding loosening during operation.

[0021] One end of the pendulum 10 that contacts the side wall of the gear arm 2 is provided with an inclined surface for fitting against the side wall of the gear arm 2. The inclined surface design makes the contact between the pendulum and the gear arm closer and the force more even, ensuring a stable clamping effect of the pendulum on the gear arm and preventing slippage. The other end of the pendulum 10 is provided with a trapezoidal block, which increases the contact area between the pendulum 10 and the material carriage roller 1, making the force of the material carriage roller 1 more concentrated when lifting the pendulum 10. At the same time, the trapezoidal structure facilitates the material carriage roller to smoothly push the pendulum 10 to swing, reducing motion resistance.

[0022] When using this utility model: When the material cart is about to enter the vacuum chamber, the gear swing arm 2 is in a free swinging state. At this time, the pendulum 10 is not subjected to the force of the material cart roller 1, and its inclined surface remains separate from the side wall of the gear swing arm 2 without applying a clamping force. The driven gear in the gear set 3 can flexibly adjust its angle with the gear swing arm 2 to avoid the material cart roller 1 jamming with the driven gear tooth tip when it enters. As the material cart gradually enters the vacuum chamber, the material cart roller 1 and the driven gear of the gear set 3 begin to mesh. During this process, the gear swing arm 2 can swing slightly around its own axis to ensure smooth meshing. As the material cart continues to go deeper, the material cart roller 1 contacts the trapezoidal block at the other end of the pendulum 10. The push force is gradually applied to make the pendulum 10 swing around the rotating shaft 7. The fixed seat 5 provides stable support for the entire mechanism. The rotating shaft bracket 6 and the rotating shaft cover 8 in the rotating shaft fixing component are firmly fixed to the rotating shaft 7 by the cover fastener 9 to ensure the stability of the rotating shaft 7 when it rotates. When the pendulum 10 swings to the preset angle, its inclined surface is closely attached to the side wall of the gear swing arm 2 and a clamping force is applied to firmly fix the gear swing arm 2 so that it can no longer swing freely. At this time, the driven gear of the gear set 3 is fully meshed with the roller 1 of the material cart. The drive gear receives the driving force of the power unit and transmits it to the driven gear to provide continuous power for the material cart.

[0023] When the material cart finishes its work and is ready to leave the vacuum chamber, the roller 1 of the material cart gradually moves out of the vacuum chamber, and the pushing force on the trapezoidal block of the pendulum 10 gradually decreases until it disappears. Under its own gravity, the pendulum 10 swings back and resets around the rotating shaft 7, releasing the clamping restriction on the gear swing arm 2. The gear swing arm 2 returns to the swingable state, and the driven gear of the gear set 3 smoothly disengages from the roller 1 of the material cart. The material cart is successfully moved out of the vacuum chamber. Throughout the process, all components work together to ensure that the power transmission is stable and uninterrupted when the material cart enters and leaves the vacuum chamber.
