Description

Technical Field

[0001] This utility model belongs to the field of metal cutting machine technology, and in particular relates to an auxiliary limiting component for a metal cutting device. Background Technology

[0002] Metal cutting machines are devices used to cut metal materials. They utilize a high-power-density laser beam to scan the material surface, heating the material to several thousand to tens of thousands of degrees Celsius in a very short time, causing the material to melt or vaporize. High-pressure gas then blows the molten or vaporized material away from the kerf, achieving the purpose of cutting the material. In summary, the existing technology has the following problems: The auxiliary limiting components in metal cutting devices are used to position and fix the workpiece during metal cutting to ensure cutting accuracy and quality. Typically, these auxiliary limiting components position the material by adjusting the position of bolts. However, during repeated adjustments and use, the threads between the bolt and nut wear, easily leading to loosening and reduced positioning stability. Furthermore, the bolt adjustment process requires multiple rotations, which is time-consuming and inconvenient. Currently, the auxiliary limiting components used in metal cutting machines lack a more stable and convenient component for limiting the material being cut. Therefore, this paper proposes an auxiliary limiting component for metal cutting devices to solve the above problems. Utility Model Content

This component offers the advantage of providing more stable and convenient limiting of the cutting material compared to existing auxiliary limiting components used in metal cutting machines. It solves the problem that existing auxiliary limiting components in metal cutting devices are used to position and fix workpieces during metal cutting to ensure cutting accuracy and quality. Typically, auxiliary limiting components position the cutting material by adjusting the position of bolts. However, during repeated adjustments and use, the threads between the bolt and nut wear, easily leading to loosening and reduced positioning stability. Furthermore, the bolt adjustment process requires multiple rotations, which is time-consuming and inconvenient. The existing auxiliary limiting components used in metal cutting machines lack a component that provides more stable and convenient limiting of the cutting material.

[0004] This utility model is implemented as follows: an auxiliary limiting component for a metal cutting device includes a cutting machine base and a fixed limiting plate. The bottom of the fixed limiting plate is fixedly connected to the top of the cutting machine base. A movable limiting plate that cooperates with the fixed limiting plate is movably connected to the top of the cutting machine base. A device shell is fixedly connected to the top of the device shell. An auxiliary control handle is fixedly connected to the top of the device shell. A main control handle that cooperates with the auxiliary control handle is movably connected to the inner cavity of the device shell. The top of the main control handle penetrates the device shell and extends to the outside of the inner cavity of the device shell. A limiting component is provided in the inner cavity of the device shell.

[0005] As a preferred embodiment of this utility model, the limiting component includes a limiting plate, the bottom of which penetrates the device shell and extends to the outer side of the inner cavity of the device shell. Two positioning holes are formed on the surface of the limiting plate, and two springs are fixedly connected to the top of the limiting plate. By setting the limiting component, when the moving limiting plate moves to an appropriate position, the limiting component has a limiting effect on the position of the moving limiting plate.

[0006] As a preferred embodiment of this utility model, the inner cavity of the device housing is fixedly connected to two positioning rods that cooperate with the positioning holes. The inner cavity of the positioning holes is movably connected to the surface of the positioning rods. By setting the positioning rods, when the limiting plate moves, it will drive the positioning holes to move along the surface of the positioning rods. The cooperation between the positioning holes and the positioning rods has a limiting effect on the movement position of the limiting plate.

[0007] In a preferred embodiment of this invention, a cylindrical frame is fixedly connected to the top of the limiting plate, and a cylindrical extrusion frame that works in conjunction with the cylindrical frame is movably connected to the rear side of the inner cavity of the device housing via a rotating shaft. The inner cavity of the cylindrical extrusion frame is movably connected to the surface of the cylindrical frame, and the surface of the main control handle is movably connected to the inner cavity of the cylindrical extrusion frame. By setting the cylindrical frame and the cylindrical extrusion frame, the cylindrical extrusion frame can generate extrusion force on the cylindrical frame when it rotates, and the cylindrical frame subjected to extrusion force can drive the limiting plate to move.

[0008] As a preferred embodiment of this utility model, a handle positioning frame for use with the main handle is fixedly connected to the left side of the auxiliary control handle. The surface of the handle positioning frame is movably connected to the inner cavity of the main control handle. By setting the handle positioning frame, pulling the main control handle will cause the main control handle to move along the surface of the handle positioning frame. The setting of the handle positioning frame has a limiting effect on the movement position of the main control handle.

[0009] As a preferred embodiment of this utility model, an adjusting plate is fixedly connected to the side of the movable limiting plate near the limiting plate. An adjusting hole is provided on the surface of the device housing to cooperate with the adjusting plate. The surface of the adjusting plate is movably connected to the inner cavity of the adjusting hole. The front side of the adjusting plate passes through the adjusting hole and extends to the outer side of the inner cavity of the adjusting hole. By setting the adjusting plate and the adjusting hole, when the movable limiting plate moves, it will drive the adjusting plate to move along the inner cavity of the adjusting hole. The cooperation of the adjusting plate and the adjusting hole has a limiting effect on the movement position of the movable limiting plate.

[0010] As a preferred embodiment of this utility model, the top of the adjusting plate is provided with a locking plate groove for use with a limiting locking plate. The surface of the limiting locking plate is in contact with the inner cavity of the locking plate groove. There are several locking plate grooves, which are evenly distributed on the top of the adjusting plate. By setting the locking plate grooves, when the adjusting plate moves to the appropriate position and the main control handle is released, the restoring force generated by the spring returning to its shape will drive the limiting locking plate to be locked into the inner cavity of the locking plate groove. The use of the limiting locking plate and the locking plate groove together has a limiting effect on the position of the adjusting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing auxiliary limiting components in metal cutting devices, which are used to position and fix workpieces during metal cutting to ensure cutting accuracy and quality, by setting up a limiting component, a limiting plate, a positioning shift hole, a spring, and a plate groove in combination. Typically, auxiliary limiting components position the material to be cut by adjusting the position of the bolts. However, during repeated adjustments and use, the bolts are prone to loosening due to thread wear between the bolts and nuts, reducing the stability of the positioning. Moreover, the bolts need to be rotated multiple times during adjustment, which is time-consuming and inconvenient. However, the auxiliary limiting components used in existing metal cutting machines do not have a component that provides a more stable and convenient way to limit the cutting material.

[0013] 2. By setting a limiting component, when the cylindrical frame moves, it will drive the limiting plate to move to the top. When the limiting plate moves, it will drive the positioning hole to move along the surface of the positioning rod. At the same time, the force generated when the limiting plate moves will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the limiting plate to pass through the device shell and extend into the inner cavity of the plate groove. The limiting component has a limiting effect on the position of the moving limiting plate. Attached Figure Description

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, an auxiliary limiting component for a metal cutting device provided in this embodiment of the present invention includes a cutting machine base 1 and a fixed limiting plate 2. The bottom of the fixed limiting plate 2 is fixedly connected to the top of the cutting machine base 1. A movable limiting plate 3 that cooperates with the fixed limiting plate 2 is movably connected to the top of the cutting machine base 1. A device housing 6 is fixedly connected to the top of the device housing 1. An auxiliary control handle 4 is fixedly connected to the top of the device housing 6. A main control handle 5 that cooperates with the auxiliary control handle 4 is movably connected to the inner cavity of the device housing 6. The top of the main control handle 5 penetrates through the device housing 6 and extends to the outside of the inner cavity of the device housing 6. A limiting component 7 is provided in the inner cavity of the device housing 6.

[0022] refer to Figure 3 The limiting component 7 includes a limiting plate 701, the bottom of which penetrates the device housing 6 and extends to the outside of the inner cavity of the device housing 6. Two positioning holes 702 are opened on the surface of the limiting plate 701, and two springs 703 are fixedly connected to the top of the limiting plate 701.

[0023] The above solution is adopted: by setting the limiting component 7, when the moving limiting plate 3 moves to the appropriate position, the limiting component 7 has a limiting effect on the position of the moving limiting plate 3.

[0024] refer to Figure 3 The inner cavity of the device housing 6 is fixedly connected to two positioning rods 8 that cooperate with the positioning holes 702. The inner cavity of the positioning holes 702 is movably connected to the surface of the positioning rods 8.

[0025] The above solution is adopted: by setting the positioning rod 8, when the limiting plate 701 moves, it will drive the positioning hole 702 to move along the surface of the positioning rod 8. The cooperation between the positioning hole 702 and the positioning rod 8 has a limiting effect on the movement position of the limiting plate 701.

[0026] refer to Figure 4 A cylindrical frame 9 is fixedly connected to the top of the limiting plate 701. A cylindrical extrusion frame 10 that works with the cylindrical frame 9 is movably connected to the rear side of the inner cavity of the device housing 6 via a rotating shaft. The inner cavity of the cylindrical extrusion frame 10 is movably connected to the surface of the cylindrical frame 9. The surface of the main control handle 5 is movably connected to the inner cavity of the cylindrical extrusion frame 10.

[0027] Using the above scheme: By setting a cylindrical frame 9 and a cylindrical extrusion frame 10, the cylindrical extrusion frame 10 can generate extrusion force on the cylindrical frame 9 when it rotates, and the cylindrical frame 9 subjected to extrusion force can drive the limit plate 701 to move.

[0028] refer to Figure 4 The auxiliary control handle 4 is fixedly connected to the left side of a handle positioning frame 11 that works with the main control handle 5. The surface of the handle positioning frame 11 is movably connected to the inner cavity of the main control handle 5.

[0029] The above solution is adopted: by setting the handle positioning frame 11, pulling the main control handle 5 will cause the main control handle 5 to move along the surface of the handle positioning frame 11. The setting of the handle positioning frame 11 has a limiting effect on the movement position of the main control handle 5.

[0030] refer to Figure 2 An adjustment plate 12 is fixedly connected to the side of the movable limiting plate 3 near the limiting plate 701. An adjustment hole 13 is opened on the surface of the device housing 6 to cooperate with the adjustment plate 12. The surface of the adjustment plate 12 is movably connected to the inner cavity of the adjustment hole 13. The front side of the adjustment plate 12 passes through the adjustment hole 13 and extends to the outer side of the inner cavity of the adjustment hole 13.

[0031] The above scheme is adopted: by setting the adjustment plate 12 and the adjustment hole 13, when the moving limit plate 3 moves, it will drive the adjustment plate 12 to move along the inner cavity of the adjustment hole 13. The cooperation of the adjustment plate 12 and the adjustment hole 13 has a limiting effect on the movement position of the moving limit plate 3.

[0032] refer to Figure 2 The top of the adjusting plate 12 is provided with a card slot 14 that works in conjunction with the limiting card plate 701. The surface of the limiting card plate 701 contacts the inner cavity of the card slot 14. There are several card slots 14 that are evenly distributed on the top of the adjusting plate 12.

[0033] The above solution is adopted: by setting the card slot 14, when the adjustment plate 12 moves to the appropriate position, the main control handle 5 is released, and the restoring force generated by the spring 703 returning to its shape will drive the limiting card 701 to be locked into the inner cavity of the card slot 14. The cooperation between the limiting card 701 and the card slot 14 has a limiting effect on the position of the adjustment plate 12.

[0034] The working principle of this utility model:

[0035] When using the auxiliary limiting component 7 of the metal cutting machine, which needs to provide more stable and convenient limiting for the cutting material, the user first places the cutting material on the top of the cutting machine base 1, ensuring the rear of the material contacts the surface of the fixed limiting plate 2. Then, the user holds the auxiliary control handle 4 and pulls the main control handle 5 towards the side closest to the auxiliary control handle 4. This causes the main control handle 5 to move along the surface of the handle positioning frame 11. When the main control handle 5 moves, it generates a compressive force on the cylindrical extrusion frame 10. The cylindrical extrusion frame 10, subjected to this compressive force, will rotate along the surface of the cylindrical frame 9 via a rotating shaft. The cylindrical frame 9, subjected to this compressive force, will move upwards. When the cylindrical frame 9 moves, it will cause the limiting plate 701 to move upwards. When the limiting plate 701 moves, it will cause the positioning shift hole 702 to move along the surface of the positioning shift rod 8. Simultaneously, the limiting plate 701 moves... The force generated causes the spring 703 to undergo elastic deformation. When the limiting plate 701 moves completely into the inner cavity of the device housing 6, it pushes the adjusting plate 12 towards the side closer to the material being cut. When the adjusting plate 12 moves, it will drive the moving limiting plate 3 towards the side closer to the material being cut. When the opposite sides of the moving limiting plate 3 and the fixed limiting plate 2 are in close contact with the surface of the material being cut, the main control handle 5 is released. The restoring force generated by the spring 703 returning to its shape will drive the limiting plate 701 through the device housing 6 and extend into the inner cavity of the plate slot 14. The cooperation of the limiting plate 701 and the plate slot 14 has a limiting effect on the position of the adjusting plate 12 and the moving limiting plate 3. The setting of the moving limiting plate 3 and the fixed limiting plate 2 has a limiting effect on the position of the material being cut. At this time, the auxiliary limiting component 7 used by the metal cutting machine completes a more stable and convenient limiting of the material being cut.

[0036] In summary, this auxiliary limiting component for a metal cutting device, through the coordinated use of limiting component 7, limiting plate 701, positioning shift hole 702, spring 703, and plate groove 14, solves the problem that existing auxiliary limiting components in metal cutting devices are used to position and fix workpieces during metal cutting to ensure cutting accuracy and quality. Typically, auxiliary limiting components position the material being cut by adjusting the position of the bolts. However, during repeated adjustments and use, the bolts are prone to loosening due to thread wear between the bolts and nuts, reducing positioning stability. Furthermore, the bolts require multiple rotations during adjustment, which is time-consuming and inconvenient. Existing auxiliary limiting components in metal cutting machines lack a more stable and convenient component for limiting the material being cut.
