Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment, and more specifically to a mechanism capable of positioning and clamping at any position in the horizontal direction. Background Technology

[0002] In the metallurgical industry, sawing is a common machining process that cuts materials into specified sizes or lengths according to requirements. In the production of long products such as pipes, bars, profiles, and plates, sawing is typically carried out by fixing the saw machine and moving the material. During the sawing process, the material must be reliably clamped to ensure stable sawing.

[0003] When sawing materials using flat rollers, the horizontal clamping of the material is usually done by edge clamping or center clamping. Because the material is free within the range of the side edges during flat roller transport, its position on the roller conveyor or horizontal platform is random when it reaches the sawing position. If edge clamping or center clamping is used, the clamping mechanism needs to push the material to one side or gather it to the center. This inevitably causes friction between the material and the roller conveyor or horizontal platform, affecting the surface quality of the sawn product. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of the present invention is to provide a mechanism that can be positioned and clamped at any position in the horizontal direction.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] A mechanism capable of positioning and clamping at any horizontal position includes a fixed support, a left jaw, and a right jaw. A chain, a drive sprocket, sprocket V, and sprocket VI are mounted on the fixed support. The chain connects to a tension sprocket, which slides within a track on the fixed support during tensioning. A linear guide rail is provided on the fixed support, allowing both the left and right jaws to slide horizontally along it. Sprockets I and II are mounted on the left jaw, and sprockets III and IV are mounted on the right jaw. The chain connects all the sprockets.

[0007] Furthermore, sprockets IV, sprocket VI, sprocket V, tension sprocket, sprocket I, drive sprocket, sprocket III, and sprocket II are sequentially linked by chains.

[0008] Furthermore, both the left and right grippers are equipped with sliders, and both the left and right grippers slide horizontally along the linear guide rail via the sliders.

[0009] Furthermore, the drive sprocket is connected to a hydraulic motor.

[0010] Furthermore, the two ends of the chain are secured by chain locking blocks installed on the fixed support.

[0011] Furthermore, the tensioning sprocket is connected to a disc spring, and the chain is tensioned by the disc spring through the tensioning sprocket.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The present invention has a positioning and clamping mechanism that can be positioned and clamped at any position in the horizontal direction. It can achieve horizontal clamping of the material on the roller conveyor within the clamping range according to the actual position of the material on the roller conveyor. During the clamping process, the material will not be displaced relative to the roller conveyor or horizontal platform, thus protecting the surface of the material to be cut very well.

[0014] (2) The material clamping mechanism of the present invention is stable. The clamping jaws are driven by a hydraulic motor. The clamping force can be adjusted by hydraulic pressure, which is convenient. In case of accidental clamping, the hydraulic motor can provide overload protection, which is safe and reliable. It can meet the clamping requirements of horizontal sawing clamping of various long materials. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0023] like Figures 1-3 As shown, a mechanism capable of positioning and clamping at any horizontal position includes a fixed support 1, a left gripper 14, and a right gripper 12. A chain 4, a drive sprocket 2, a sprocket V9, and a sprocket VI10 are mounted on the fixed support 1. The chain 4 connects to a tension sprocket 3, which slides within a track on the fixed support 1 during tensioning. A linear guide rail 13 is provided on the fixed support 1, allowing both the left gripper 14 and the right gripper 12 to slide horizontally along the linear guide rail 13. A sprocket I5 and a sprocket II6 are mounted on the left gripper 14, and a sprocket III7 and a sprocket IV8 are mounted on the right gripper 12. The chain 4 connects all the sprockets; specifically, sprocket IV8, sprocket VI10, sprocket V9, tension sprocket 3, sprocket I5, drive sprocket 2, sprocket III7, and sprocket II6 are sequentially connected via the chain 4.

[0024] In this embodiment, both the left gripper 14 and the right gripper 12 are equipped with sliders, and both the left gripper and the right gripper slide horizontally along the linear guide rail 13 via the sliders.

[0025] The drive sprocket 2 is connected to the hydraulic motor 15 and is driven by the hydraulic motor 15.

[0026] The two ends of the chain 4 are fixed by chain locking blocks 11 installed on the fixed support 1. The tensioning sprocket 3 is connected to a disc spring. The chain 4 is tensioned by the disc spring through the tensioning sprocket 3, thereby ensuring that the entire gear train runs smoothly without jamming.

[0027] The mechanism described in this invention, capable of positioning and clamping at any position in the horizontal direction, operates on the following principle:

[0028] When the material is positioned slightly to the right and needs to be clamped, the drive sprocket 2 rotates clockwise under the action of the hydraulic motor 15. At this time, the left and right grippers are unloaded, and the left gripper 14 and right gripper 12 move towards the center simultaneously. When the right gripper 12 touches the right side of the material, it stops moving first due to the material's obstruction. The state at this time is as follows: Figure 4As shown, the left gripper 14 continues to move forward under the drive of the drive sprocket 2. When the left gripper 14 touches the left side of the material, the left gripper 14 and the right gripper 12 establish an internal force to hold the material under the torque of the hydraulic motor 15. At this time, the material is firmly held in place. When the material is cut and needs to be released, the drive sprocket 2 rotates counterclockwise under the action of the hydraulic motor 15, and the left gripper 14 and the right gripper 12 move to both sides at the same time, and the two grippers return to their initial positions one after the other.

[0029] When the material is positioned slightly to the left and needs to be clamped, the drive sprocket 2 rotates clockwise under the action of the hydraulic motor 15. At this time, the left and right grippers are unloaded, and the left gripper 14 and right gripper 12 move towards the center simultaneously. When the left gripper 14 touches the left side of the material, it stops moving first due to the material's obstruction. The state at this time is as follows: Figure 5 As shown, the right gripper 12 then continues to move forward under the drive of the drive sprocket 2. When the right gripper 12 touches the right side of the material, the left gripper 14 and the right gripper 12 establish an internal force to hold the material under the torque of the hydraulic motor 15. At this time, the material is firmly held in place. When the material is sawn and needs to be released, the drive sprocket 2 rotates counterclockwise under the action of the hydraulic motor 15, and the left gripper 14 and the right gripper 12 move to both sides at the same time, and the two grippers return to their initial positions one after the other.

[0030] As can be seen, regardless of where the material is located within the clamping range, the left and right jaws can firmly clamp it in place according to its position.

[0031] The components and structures not described in detail in the above embodiments are well-known components, common structures or common means in this industry, and will not be described one by one here.

[0032] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
