Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery manufacturing, in particular to an engineering machinery manufacturing protection device. Background Art

[0002] Engineering machinery refers to the general term for construction machinery used in engineering construction, which is widely used in construction, water conservancy, transportation, mining and other fields. Engineering machinery manufacturing is the process of converting design drawings into actual mechanical products, including the production of various types of equipment such as excavators, loaders, cranes, road rollers, etc., including basic processes such as cutting, forming and connecting of metal materials.

[0003] For example, the patent application number published on the China Patent Network is: 202221502099.1, and the patent name is: A mechanical manufacturing protection device, including a cutting machine, wherein the top of the cutting machine is movably connected to a processing table, the processed steel is placed on the processing table, and the handle is turned. The rotation of the handle will drive the threaded rod to rotate inside the support plate, and the rotation of the threaded rod will drive the push plate to move. When the push plate moves, the second slider moves inside the second slide groove, and the push plate moves downward when the bolt is turned, thereby driving the positioning plate to move downward. After moving to contact with the processed steel, it stops rotating, thereby limiting the processed steel. The user pushes the push handle to drive the first slider at the bottom of the processing table to move inside the first slide groove, avoiding the user using his hands to support the processed steel during cutting, inadvertently causing damage to the hand, and causing unnecessary trouble.

[0004] However, the overall size of existing engineering machinery parts is relatively large. Due to the possible damage caused by the mechanical action of equipment parts, tools, workpieces or splashing solid and fluid substances, manual operation during loading or moving is prone to mechanical damage. To avoid damage, operators may need to operate more carefully and slowly, which affects production speed.

[0005] Secondly, manual contact with metal construction machinery may trigger electrical injuries. Electrical hazards are caused by electric shock or burns, which may come from exposed wires, leakage or improper electrical operation of the equipment. Electrical hazards may cause serious injuries or even death, posing a threat to the life safety of workers. Once an electrical accident occurs, the equipment may need to be shut down for a long time for repairs, affecting production progress.

[0006] In addition, high temperatures will be generated due to friction during the processing of metal materials, and users will suffer burns due to the effect of heat conduction when they come into contact with metal materials.

[0040] As a technical optimization solution of the present invention, by setting the positioning structure 7, the mechanical engineering workpiece 3 can be automatically fixed when the shielding frame 15 is flipped, ensuring the stability of the workpiece during the cutting process, improving the processing accuracy and product quality, and reducing the cutting error caused by the movement of the workpiece.

[0041] refer to Figure 4 The pushing structure 6 includes a movable block 25 fixedly connected to the four corners of the top of the shielding frame 15, the inner side of the movable block 25 is laterally connected to a limit rod 26 and a second reciprocating screw 27, the limit rod 26 is fixedly connected to the movable block 25, the second reciprocating screw 27 is movably connected to the movable block 25 through a bearing, and sleeve plates 28 are fixedly connected to both sides of the top of the connecting frame 20, the sleeve plates 28 are respectively sleeved on the surfaces of the limit rod 26 and the second reciprocating screw 27, the second reciprocating screw 27 is threadedly connected to the sleeve plates 28, and a driving structure 29 is provided on the surface of the shielding frame 15, and the driving structure 29 can use the power of the transmission motor 9 to drive the second reciprocating screw 27 to rotate.

[0042] As a technical optimization solution of the present invention, the horizontal movement of the connecting frame 20 and the workpiece is achieved through the coordinated work of the movable block 25, the limit rod 26, the second reciprocating screw 27 and the sleeve plate 28, which not only simplifies the feeding process, but also improves the accuracy and efficiency of feeding, making the cutting process more continuous and stable.

[0043] refer to Figure 3 The driving structure 29 includes a pulley 30 which is respectively fixedly connected to the output end of the transmission motor 9 and one end of the second reciprocating screw 27 , and a belt 31 is sleeved on the surface of the pulley 30 .

[0045] refer to Figure 3 An extension rod 32 is fixedly connected to one side of the base 1 close to the pulley 30, and a tensioning wheel 33 is movably connected to the side of the extension rod 32 away from the base 1 through a bearing.

[0047] refer to Figure 4 Trapezoidal rods 34 are installed at the four corners inside the connecting frame 20. The trapezoidal rods 34 are connected to the connecting frame 20 by connecting pieces. The trapezoidal rods 34 can be vertically lifted and lowered inside the connecting frame 20 by using the connecting pieces. The bottom of the trapezoidal rods 34 can contact the top of the base 1. A spring plate 35 is fixedly connected to the inner side of the trapezoidal rods 34. The side of the spring plate 35 away from the trapezoidal rods 34 contacts the outer side of the clamping plate 24. When the trapezoidal rods 34 swing with the shielding frame 15, they can be squeezed by the base 1 and use the inner inclined surface to push the clamping plate 24 to move inward through the guidance of the guide rod 22 during the rising process.

[0048] As a technical optimization solution of the present invention, by setting a trapezoidal rod 34 and a spring plate 35, the connecting frame 20 can automatically adjust the position of the clamping plate 24 during the flipping process. When the trapezoidal rod 34 is squeezed by the base 1, the inclined surface on its inner side pushes the clamping plate 24 to move inward, further fixing the mechanical engineering workpiece 3, improving the adaptability and flexibility of the positioning structure 7, and allowing the workpiece to be stably fixed in different positions.

[0049] refer to Figure 2 A push plate 36 is fixedly connected to the outer side of the clamping plate 24 , and a side of the push plate 36 away from the clamping plate 24 is arranged in an inclined shape, and the push plate 36 is elastic.

[0050] As a technical optimization solution of the present invention, by setting a push plate 36, the splint 24 can have the effect of cleaning the debris on the top of the base 1 during the movement, avoiding the movement of the splint 24 and the mechanical engineering workpiece 3 from being affected, and improving the stability of power transmission.

[0051] The working principle and use process of the present invention are as follows: the base 1 is firmly placed in the designated position, and the cutting assembly 2 is installed inside the base 1. The core components of the assembly include a transmission motor 9, a transmission rod 10 and a sharp saw blade 11. In the initial state, these components are all in a non-working state, waiting to be activated. Once the transmission motor 9 receives a start signal, it will start to operate quickly, driving the transmission rod 10 connected thereto to rotate synchronously. The transmission rod 10 transmits the rotational power to the saw blade 11 through the bevel gear 12 mechanism, so that the saw blade 11 starts to rotate, making full preparations for the subsequent cutting process. At the same time, When the transmission rod 10 rotates, the rotation of the transmission rod 10 also triggers the linkage structure 5, which is composed of a first reciprocating screw 16, a stable bracket 17, an extrusion frame 18 with an inclined surface, and a force-bearing rod 19. As the transmission rod 10 rotates, the first reciprocating screw 16 begins to push the extrusion frame 18 on the bracket 17 to move horizontally. The two sides of the extrusion frame 18 are designed to be inclined. When it moves to the two sides of the extrusion frame 18, its inclined surface contacts the force-bearing rod 19 and produces an extrusion effect. This extrusion force is transmitted to the shaft rod 14 through the force-bearing rod 19, thereby driving the shielding frame 15 to move with the shaft rod 1 4 is flipped, the shielding frame 15 is gradually closed during the flipping process, and finally completely shields the processing area of ​​the cutting assembly 2, forming a relatively closed working environment, which not only protects the operator from being hurt by flying debris, but also improves the safety of the processing process. As the shielding frame 15 flips, the connecting frame 20 installed on the top of it also flips synchronously. The connecting frame 20 is designed with a trapezoidal rod 34, a guide rod 22, a pressure plate 23 and a clamping plate 24 and other components. During the flipping process, the bottom of the trapezoidal rod 34 contacts the top of the base 1 and is gradually squeezed. The side of the shielding frame 15 has an inclined surface, and this extrusion effect is converted into a power that pushes the clamping plate 24 to move inward through the inclined surface. The clamping plate 24 moves smoothly to both sides of the mechanical engineering workpiece 3 under the guidance of the guide rod 22, and the workpiece is firmly fixed by the pressure plate 23. When the shielding frame 15 is flipped into place and successfully shields the processing area, the pulley 30 on the surface of the shielding frame 15 starts to work. It uses the cooperation between the belt 31 and the tensioning wheel 33 to transmit the power of the transmission motor 9 to the second reciprocating screw 27. With the tensioning of the belt 31 and the transmission of power, the second reciprocating screw 27 starts to rotate. The rotation of the second reciprocating screw 27 pushes the sleeve plate 28 to move horizontally along the limit rod 26 through the action of the thread. The sleeve plate 28 is closely connected to the connecting frame 20, so the connecting frame 20 also moves accordingly. At this time, the mechanical engineering workpiece 3 that has been fixed inside the connecting frame 20 slides smoothly along the top of the base 1 under the push of the clamping plate 24.During the sliding process, the workpiece passes over the rotating saw blade 11, and the saw blade 11 cuts the workpiece quickly and accurately. The entire processing process is stable and efficient, ensuring the quality and accuracy of the workpiece. When the connecting frame 20 continues to move and pushes the mechanical engineering workpiece 3 completely through the other side of the saw blade 11, the force-bearing rod 19 on the surface of the shielding frame 15 moves from the horizontal plane of the extrusion frame 18 to the inclined plane on the other side, and is again squeezed by the inclined plane of the extrusion frame 18. This squeezing force causes the force-bearing rod 19 to drive the shaft rod 14 to flip in the opposite direction, thereby opening the shielding frame 15 and allowing the mechanical engineering workpiece 3 to be released from a fixed state. At this time, the processed workpiece can be safely taken out and subsequently processed.

[0052] To sum up: the engineering machinery manufacturing protection device realizes automation and safety in the cutting process by integrating the base 1, the cutting component 2, the mechanical engineering workpiece 3, the shielding structure 4, the linkage structure 5, the positioning structure 7 and the pushing structure 6. The shielding structure 4 effectively prevents cutting splashes, the linkage structure 5 ensures the synchronization of shielding and cutting, the positioning structure 7 stabilizes the workpiece, and the pushing structure 6 realizes automatic feeding and cutting of the workpiece.
