Description

Technical Field

[0001] This application relates to the field of equipment for processing heavy plates, and in particular to a transmission clamping mechanism for cutting heavy plates. Background Technology

[0002] Heavy plates are a type of steel material widely used in construction, bridges, and machinery manufacturing. Cutting is a crucial step in the production and processing of heavy plates. Currently, heavy plate cutting is typically done mechanically, with the transmission and clamping mechanism being a key component of the cutting equipment. This mechanism stably transports and clamps the heavy plates to ensure cutting accuracy and efficiency.

[0003] However, existing transmission clamping mechanisms often suffer from unstable clamping force and wobbling during transport when clamping thick plates. This not only affects cutting accuracy but may also damage the cutting equipment and the thick plates. Therefore, a transmission clamping mechanism capable of stably clamping and transporting thick plates is needed. Utility Model Content

[0004] To alleviate the shaking of thick plates during the conveying process and improve cutting accuracy, this application provides a transmission clamping mechanism for cutting thick plates.

[0005] The transmission clamping mechanism for cutting wide and thick plates provided in this application adopts the following technical solution:

[0006] A transmission clamping mechanism for cutting wide and thick plates includes a frame, the frame being provided with a conveying device, the conveying device including a transmission seat disposed on the frame, a driving wheel and a driven wheel being rotatably connected to the transmission seat, a conveyor belt being wound between the driving wheel and the driven wheel on the frame, and a drive motor for controlling the rotation of the driving wheel being disposed on the frame.

[0007] A movable seat is movably mounted on the frame. A drive assembly for controlling the lifting and lowering of the movable seat is mounted on the frame. The movable seat is equipped with multiple limit wheels. A support arm is provided on the movable seat corresponding to the position of each limit wheel. The limit wheels are connected to the movable seat through the support arm. An elastic buffer assembly is provided on the support arm.

[0008] By adopting the above technical solution, the conveying device consists of a driving wheel, a driven wheel, and a conveyor belt, which can smoothly convey wide and thick plates. Multiple limit wheels are set on the moving seat, and the elastic buffer component pushes the support arm to drive the limit wheels to rotate towards the conveying seat, providing a stable clamping force, effectively reducing the shaking of wide and thick plates during the conveying process, and helping to improve cutting accuracy.

[0009] Optionally, the elastic buffer assembly includes a base fixedly connected to the movable seat, a support arm slidably disposed on the base, and a tension spring connected between the support arm and the base, the tension spring pushing the limiting wheel toward moving towards the conveyor belt.

[0010] By adopting the above technical solution, the limiting wheel can adhere tightly to the thick plate on the conveyor belt under the action of the tension spring, providing a more stable and reliable clamping force. At the same time, the elasticity of the tension spring can also absorb the vibration and impact during the conveying of the thick plate to a certain extent, further improving the clamping stability and cutting accuracy.

[0011] Optionally, the drive assembly includes an electric cylinder hinged to the frame, the movable seat is hinged to the frame via a cantilever, and the piston rod of the electric cylinder is hinged to the cantilever.

[0012] By adopting the above technical solution, using an electric cylinder hinged to the frame as a power source, and through the hinged connection of the cantilever and piston rod, the lifting control of the moving seat is realized.

[0013] Optionally, an anti-slip pad is provided on the outer wall of the conveyor belt.

[0014] By adopting the above technical solution, anti-slip pads are installed on the outer wall of the conveyor belt, which effectively increases the friction between the conveyor belt and the thick plate, reduces the slippage or fall of the thick plate during the conveying process, and further improves the conveying stability and cutting safety of the thick plate.

[0015] Optionally, two transmission seats are slidably arranged on the frame, with the two transmission seats spaced apart, and the frame is provided with a control component for controlling the two transmission seats to move closer to or further apart from each other;

[0016] A drive shaft is rotatably connected to the frame. The output shaft of the drive motor is coaxially and fixedly connected to the drive shaft. Splined shafts are coaxially and fixedly connected to the two corresponding drive seats. Splined sleeves are fixedly connected to the drive wheels on the two drive seats. The splined sleeves are slidably fitted onto the corresponding splined shafts.

[0017] By adopting the above technical solution and setting up an adjustable-spacing transmission seat and control components, adaptability to plates of different widths and thicknesses is achieved. Specifically, the transmission seat slides on the frame, achieving synchronous movement through the cooperation of a splined shaft and a splined sleeve.

[0018] Optionally, the control component includes a bidirectional screw rotatably connected to the frame, and two threaded sleeves are fixedly connected to the two transmission seats. The bidirectional screw passes through the threaded sleeves and is threadedly connected to the threaded sleeves, and the threaded sections of the bidirectional screw corresponding to the two threaded sleeve positions have opposite directions of rotation.

[0019] By adopting the above technical solution, the control component uses a threaded connection structure of a bidirectional screw and a screw sleeve. The distance between the two transmission seats can be quickly and accurately adjusted by rotating the bidirectional screw. This further improves the flexibility and adaptability of the equipment and can meet the cutting needs of wide and thick plates of different widths.

[0020] Optionally, several side wheels are rotatably connected to the opposite sides of the two drive seats to prevent the thick plate from detaching from the drive seats.

[0021] By adopting the above technical solution, several side wheels are rotatably connected on the opposite sides of the two transmission seats. The side wheels block the thick plate, thereby preventing the thick plate from detaching from the transmission seat.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The conveying device consists of a driving wheel, a driven wheel, and a conveyor belt, which can smoothly convey wide and thick plates. Multiple limit wheels are set on the moving seat, and the elastic buffer component pushes the support arm to drive the limit wheels to rotate towards the conveying seat, providing a stable clamping force, effectively reducing the shaking of wide and thick plates during the conveying process, and helping to improve cutting accuracy.

[0024] 2. An adjustable-spacing transmission seat and control components were installed to adapt to plates of different widths and thicknesses. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a transmission clamping mechanism for cutting thick plates. For example... Figure 1 and Figure 2 The transmission clamping mechanism for cutting wide and thick plates includes a frame 1, on which a conveying device is mounted for stably conveying wide and thick plates. Specifically, the conveying device includes two transmission seats 11 slidably mounted on the frame 1, spaced apart. A control component 3 is mounted on the frame 1 to control the two transmission seats 11 to move closer or further apart, accommodating wide and thick plates of varying widths. Multiple side wheels 12 are rotatably connected to the opposite sides of each of the two transmission seats 11 to prevent the wide and thick plates from detaching from the transmission seats 11.

[0031] Two drive wheels 13 and driven wheels 14 are rotatably connected to each of the two drive seats 11. Between the drive wheels 13 and driven wheels 14, a conveyor belt 15 is wound around the frame 1 for carrying and conveying wide and thick plates. To drive the drive wheels 13 to rotate, a drive shaft 2 is rotatably connected to the frame 1. Splined shafts 21 are fixedly connected to the drive shafts 11 at the corresponding positions on the two drive seats 11. Splined sleeves 22 are fixedly connected to the drive wheels 13 on the two drive seats 11, and the splined sleeves 22 are slidably fitted onto the corresponding splined shafts 21. A drive motor 23 is fixedly connected to the frame 1, and the output shaft of the drive motor 23 is fixedly connected to the drive shaft 2 at the same axis. Through the cooperation of the splined shafts 21 and splined sleeves 22, the conveyor belts 15 on the two drive seats 11 move synchronously.

[0032] The control component 3 includes a bidirectional screw 31 rotatably connected to the frame 1, and two threaded sleeves 32 fixedly connected to each of the two transmission seats 11. The bidirectional screw 31 passes through the threaded sleeves 32 and is threadedly connected to them. The threaded sections of the bidirectional screw 31 corresponding to the positions of the two threaded sleeves 32 have opposite directions of rotation. When the bidirectional screw 31 rotates, due to the opposite directions of rotation of the threaded sections, the two threaded sleeves 32 will move in opposite directions, thereby causing the two transmission seats 11 to move closer or further apart, achieving width adjustment.

[0033] To achieve stable clamping of the thick plate, movable seats 4 are movably provided on opposite sides of the two transmission seats 11. The movable seats 4 can move up and down on the corresponding frame 1 via guide rails or other structures, or they can be hinged to the corresponding transmission seats 11. In this embodiment, the movable seats 4 are hinged to the frame 1 via cantilever 41. To control the lifting and lowering of the movable seats 4, a drive assembly 5 is provided on the frame 1, specifically including an electric cylinder 51 hinged to the frame 1, with the piston rod of the electric cylinder 51 hinged to the cantilever 41. When the electric cylinder 51 extends or retracts, the movable seats 4 can be driven to rise and fall through the lever action of the cantilever 41, thereby adjusting the distance between the limit wheel 42 and the conveyor belt 15.

[0034] like Figure 2 and Figure 3The movable seat 4 is equipped with multiple limiting wheels 42 for clamping thick plates and preventing them from swaying during conveying. To enhance clamping stability and adaptability, the movable seat 4 is equipped with a support arm corresponding to each limiting wheel 42, and the limiting wheels 42 are connected to the movable seat 4 via the support arms. The support arms are also equipped with elastic buffer components 6, specifically including a base 61 fixedly connected to the movable seat 4, with the support arm slidably mounted on the base 61 and connected to the base 61 via a tension spring 62. The tension spring 62 pushes the support arm and the limiting wheels 42 towards the conveyor belt 15, thereby providing a stable clamping force.

[0035] To increase the friction between the conveyor belt 15 and the thick plate and prevent the thick plate from sliding or falling off during conveying, an anti-slip pad (not shown in the figure) is provided on the outer wall of the conveyor belt 15. The anti-slip pad can be made of materials with good friction properties such as rubber or polyurethane.

[0036] The principle of this embodiment is as follows: In use, the thick plate is first placed on the conveyor belt 15. Then, the height of the moving seat 4 is adjusted by the electric cylinder 51 so that the limiting wheel 42 is in close contact with the thick plate. Next, the drive motor 23 is started, which drives the conveyor belt 15 to move through the transmission device, thereby conveying the thick plate. During the conveying process, the limiting wheel 42 provides a stable clamping force under the action of the tension spring 62 to prevent the thick plate from shaking. At the same time, the anti-slip pad increases friction to prevent the thick plate from sliding or falling off. When it is necessary to adjust the conveying width to accommodate thick plates of different widths, the distance between the two transmission seats 11 can be quickly and accurately adjusted by simply rotating the bidirectional screw 31.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
