For example, "connected" can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] Figure 1 , 9 The invention shows an implementation form of an automatic cutting system for processing curved surfaces of a workpiece, which includes:

[0067] The power assembly 1 is configured to use a motor and a reducer or coupling etc. matched therewith to provide the rotational force required for the tooling to work;

[0068] A tool 2 connected to the power output end of the power assembly to clamp the workpiece to be cut, which is used to support and limit the workpiece so that it can rotate at high speed under the drive of the power mechanism;

[0069] An actuator 3 for cutting the workpiece, which can be set as a plasma or laser cutting gun head according to actual use needs, and is used to cut the workpiece through the cutting force it generates;

[0070] The power output end is provided with a camshaft 4, and the camshaft is provided with a first cam surface 5 and a second cam surface 6 that match each other at a preset distance. In this component, the camshaft has a special-shaped surface structure design, so that it can give a force to the parts in contact with it during its rotation, so that the contact parts can make corresponding position adjustments according to the surface structure of each cam surface;

[0071] The actuator is mounted on the limiting plate 8 through the matched first transmission assembly 7, and the first cam surface contacts the free end of the first transmission assembly to drive the spatial position of the actuator to change up and down during the rotation of the first cam surface. In this structure, the actuator is mounted on the first transmission assembly, and through the structural design of its position and surface shape, that is, from a longitudinal perspective, its upper surface has a special-shaped structure. Therefore, when the first transmission assembly is in contact with the upper surface, the position of the actuator in the longitudinal direction will be adjusted up and down due to the change in the height position on its upper surface, so as to cut the workpiece to be cut into a curved surface structure with a high and low surface shape;

[0072] The limiting plate is installed on the fixed plate 10 through the matching second transmission component 9. The first cam surface contacts the protrusion on the limiting plate to drive the spatial position of the actuator to change left and right during the rotation of the second cam surface. The limiting plate installed on the actuator can be adjusted to the left and right under the action of the second transmission component. Further, through the position and surface structure design of the second cam surface, that is, from a longitudinal point of view, its side has a special-shaped structure. Therefore, when the second transmission component contacts the side surface, the horizontal position of the actuator will be adjusted left and right due to the surface shape of its side surface to meet the needs of workpiece cutting without damaging the tooling. In this scheme, a speed-regulating motor is used to provide rotational power so that the tooling connected to the motor can drive the workpiece to rotate and drive the camshaft to rotate at the same time. The rotation of the camshaft further drives the plasma or laser cutting gun head to move up and down, thereby completing the cutting process of complex spatial special-shaped curves of the workpiece. The degree of automation and accuracy of the processing process meet the use requirements, and the camshaft mechanism is stable and reliable, with a simple structure and low equipment manufacturing cost, which effectively improves production efficiency and product yield.

[0073] like Figure 1-2 In another example, the first conductive component is configured to include:

[0074] At least two first slide rails 11 are arranged on the limiting plate;

[0075] The first slider 12 matched with the first slide rail, in this structure, through the way of matching the slide rail and the slider, it has a long working life, high precision, simple structure and reliable cost;

[0076] Among them, one end of the first slider is connected to the actuator through a connecting mechanism 13, and the other end of the first slider contacts the surface of the first cam surface through a matching roller mechanism 14. In this structure, the actuator is fixed to the first slider through the connecting mechanism, and a matching roller mechanism is set at the other end of the first slider, so that when the first cam surface rotates, the position height of the contact surface between it and the roller mechanism changes, thereby driving the first slider to slide up and down in the first slide rail. The setting of multiple first slide rails makes it more stable in the longitudinal space and ensures its operation stability. In actual use, a matching card plate 15 can also be set on the outside of the first slider to limit its structure. Of course, the first slider can also be set so that the sliding part is set as a special-shaped structure to make its structural stability better during longitudinal movement.

[0077] like Figure 3 , 9 In another example, the connection mechanism is configured to include:

[0078] A connecting plate 16 that cooperates with the actuator;

[0079] A fixing section 17 cooperating with the connecting plate;

[0080] The end of the fixed section that matches the first slider is provided with a first limiting groove 18 into which the first slider can extend;

[0081] The fixed section is also provided with a strip hole 19 for adjusting the extension position of the first slider. In this structure, the actuator is fixed by a connecting plate, which can be connected by screws or welding. A first limiting groove is provided on the fixed section, so that one end of the first slider can be partially inserted into the first limiting groove, and the extension depth of the first slider can be further adjusted through the strip hole to ensure that the initial position of the actuator is controllable, thereby cooperating with the processing needs of workpieces of different heights.

[0082] like Figure 5 , 10 -11. In another example, the roller mechanism is configured to include:

[0083] A T-shaped transmission member 20 rotatably connected to the roller 45;

[0084] A mounting member 21 matched with the first slider;

[0085] Wherein, a fixing column 22 matching with the mounting member is arranged on the platform of the transmission member;

[0086] The mounting member is provided with a second limiting groove 23 into which the first sliding block can extend;

[0087] The mounting member is provided with an extension portion 24 on the side cooperating with the transmission member, and a limiting hole 25 cooperating with the fixing column is provided in the extension portion. In this structure, the roller is installed and limited by the free end extending out of the T-shaped transmission member, and the mounting member is used to realize the switching connection between the first slider and the transmission member, and at the same time cooperate with the transmission member in space to avoid it, so as to ensure its smoothness when working with the first cam surface, prevent it from interfering with it and affecting its working effect, and at the same time reduce the weight of the equipment, reduce the wear and damage to the first cam when it is working, and the second limiting groove is used for the second slider to extend into, and in this structure, they are connected and fixed by matching screws, and the matching of the fixing column and the limiting hole ensures the stability of the spatial connection between the two and the effective transmission of the position change of the second slider.

[0088] like Figure 5-6 , 8-9, in another example, the second transmission assembly is configured to include:

[0089] A second slide rail 26 disposed on the limiting plate;

[0090] A second slider 27 is arranged on the fixed plate and cooperates with the second slide rail. In this structure, the second slider cooperates with the second slide rail so that the limiting plate can move left and right in space, thereby coordinating with different processing processes and processing effects;

[0091] The fixing plate is configured as an L-shaped structure, and the limiting plate is provided with at least one protruding guide member 28 at a position matching with the bent side of the fixing plate. In this structure, the position of the horizontal movement thereof is guided by the matching guide member provided on the limiting plate;

[0092] A through hole 29 for the guide to pass through is provided on the bent side of the fixed plate, a matching knob 30 is provided at the position where the guide passes through the through hole, and a matching first elastic element 31 is provided on the guide. In this structure, the second slider moves left and right under the action of the second cam surface, driving the limiting plate to move left and right in space, thereby moving the horizontal position of the actuator, and the function of the first compulsory element is to limit the stroke of the limiting plate movement, while ensuring that it can return to the initial position or enter the next position under the action of the elastic force after moving to the bent side of the fixed plate, thereby ensuring the smoothness and continuity of its operation to match the specific workpiece processing surface shape.

[0093] like Figure 2-4 In another example, the tooling is configured to include:

[0094] The mounting seat 32 disposed on the camshaft may be designed as an integral unit with the camshaft or as a separate unit, and a through slot is disposed thereon so that the hinged fixed axis can be moved along the direction of the slot;

[0095] A fixed shaft 34 is arranged on the mounting seat and cooperates with the workpiece 33 to be processed. In this structure, the workpiece is supported by the fixed shaft, so that the structural stability of the hollow workpiece in the longitudinal space is better, and at the same time, during the processing, the end face cutting of the workpiece will not cause instability factors, thereby ensuring the stability of the workpiece during continuous processing. In actual use, according to specific needs, multiple sections of fixed threads can be arranged on the fixed shaft, and multiple limiting blocks with external structures that cooperate with the inner wall of the workpiece can be arranged on the fixed shaft, that is, each limiting block rotates according to the length and position of the workpiece. The corresponding limiting block is on the fixed shaft, and the workpiece is stuck on the fixed shaft through the external structure that cooperates with the inner wall of the workpiece, and the inner wall of the workpiece is supported at the same time, ensuring that when processing thin-walled workpieces, its special-shaped surface and other positions will not be deformed. According to needs, a matching silicone layer can be arranged on the outer wall of the limiting block to reduce the wear on the workpiece when it is inserted, and absorb the force generated when the workpiece is working, thereby ensuring its working stability.

[0096] A clamp 35 is movably arranged on the frame to limit the end of the fixed shaft. In this structure, the mounting shaft in the longitudinal direction is clamped by the clamp to ensure that the spatial position of the fixed shaft during the processing will not be deviated by the mechanical vibration generated by the cutting or the motor operation.

[0097] A support assembly 36 is provided on the frame to limit the longitudinal position of the fixed axis. In this structure, the support assembly is used to support and limit the workpiece with a certain height in space, thereby ensuring its stability during processing and preventing the surface of the workpiece from shaking due to the excessive length of the workpiece, thereby causing defective products;

[0098] The support assembly is configured to include a first bearing 37 matched with the fixed shaft, and a U-shaped limiting member 38 arranged on the frame to limit the position of the first bearing. The first bearing is arranged inside the groove of the limiting member through a matching fixing pin 39. In this structure, a matching thin plate is arranged on the frame, and a U-shaped limiting member is installed inside the plate, so that the rotatable fixed shaft is not limited when the whole is turned over. The function of the fixing pin is to limit the spatial position of the fixed shaft after it reaches the specified position. Further, through the function of the bearing, the fixed shaft can be stuck inside the limiting member, but it will not affect its rotation.

[0099] The fixed shaft and the mounting seat are connected via an adapter 40, and the adapter and the mounting seat are connected in a hinged manner. Through the hinged setting of the adapter, the fixed shaft can be rotated as needed to facilitate the workpiece to be inserted into the fixed shaft, and the workpiece can also be taken out after processing.

[0100] The inner ring of the first bearing is provided with a through hole 41 that matches the structure of the outer part of the workpiece, and the adapter is provided with a third limiting groove (not shown) that matches the structure of the outer part of the workpiece, and the workpiece is concentrically arranged with the fixed shaft, and the minimum inner diameter of the workpiece is configured to be larger than the diameter of the fixed shaft. In this structure, by arranging a through hole that matches the external structure of the workpiece inside the first bearing, the insertion and fixation of the workpiece are facilitated. For example, if the workpiece adopts a flat tube structure, when it is inserted into the through hole, it can fix the workpiece without affecting its rotation smoothness. At the same time, through the structural design of the third limiting groove on the adapter, when the fixed shaft is installed on the adapter, the position of the workpiece can also be limited. The third limiting groove can be a direct diameter enlargement of the position of the fixed shaft, or a recessed groove that can limit the end face of the workpiece can be set in the enlarged groove to ensure the stability of its structural matching, and the diameter of the fixed shaft and the workpiece is limited, so that the fixed shaft has a predetermined distance from the inner wall of the workpiece to prevent damage to the fixed shaft during the processing of the workpiece.

[0101] like Figure 4 , 7 In another example, the card is configured to include:

[0102] A connecting rod 42 that passes through a side wall of one side of the frame;

[0103] A step seat 43 connected to the connecting rod through the second bearing is provided with a limiting hole 44 for inserting the fixed shaft. In this structure, the clamp can be regarded as an upper tooling that cooperates with the tooling to limit the fixed shaft thereon, and the workpiece is installed on the upper and lower tooling to ensure the rotational motion accuracy value. At the same time, through the segmented structural design of the tooling, when it is necessary to take out the workpiece, the connecting rod is lifted to separate the limiting hole on the step seat from the fixed shaft, thereby completing the separation of the structure. After the workpiece is installed on the fixed shaft, the connecting rod is pressed down to limit the fixed shaft, thereby ensuring the stability of the cooperation between the components during operation.

[0104] like Figure 7 , in another example, the free end of the connecting rod is provided with a limiting ring 46;

[0105] The connecting rod is provided with a second elastic element 47 on one side matching with the step seat;

[0106] The top of the fixed shaft is provided with an outwardly extending protrusion (not shown), and the limiting hole is provided with an extension groove (not shown) matched with the protrusion. In this structure, the downward position of the connecting rod is controlled by the limiting ring to prevent it from being separated from the tooling and the frame due to the action of gravity after the fixed shaft is flipped, and a second installation is required when it is used next time. The structure of the step seat allows the upward position of the connecting rod to be limited, and further through the action of the second elastic element, it is given a restoring force. At the same time, the stability of the fixed shaft can also be suppressed by the initial force of the second elastic element, so as to ensure the reliability of its connection limitation. In actual use, a matching bearing can be set at the position where the connecting rod passes through the frame, and a matching bearing can also be set at the position where the limiting ring and the second elastic element contact the surface of the frame to ensure that its rotation will not cause any interference.

[0107] In another example, the inner walls opposite to the limiting member are respectively provided with special-shaped grooves (not shown) for limiting the position of the second bearing, and the outer wall of the fixed shaft is provided with at least two special-shaped sliding blocks (not shown) that cooperate with the grooves. In this structure, in principle, the special-shaped grooves relatively arranged on the inner sides of the limiting member can make the special-shaped sliding blocks on the bearing slide in smoothly, but because the flipping trajectory of the second bearing on the fixed shaft is not horizontal when it flips and enters the special-shaped groove, the special-shaped groove has an arc in space that cooperates with the flipping trajectory of the second bearing to ensure the smoothness of the cooperation between the two, and at the same time ensure the stability between the structural parts, to prevent the second bearing and the limiting member from having a small internal gap, resulting in poor insertion, or the second bearing and the limiting member from having a large internal gap, resulting in no clamping effect.

[0108] In another example, the power output end is provided with a third bearing (not shown) at a position penetrating the frame, and the camshaft is provided with a fourth bearing (not shown) at a position matching the surface of the frame. In this structure, by providing the third bearing and the fourth bearing, the structure will not generate any interference between the rotation of the component and the frame. According to different needs, a plane bearing can be provided so that its rotation on the horizontal plane is not interfered, and a bearing can be provided longitudinally so that the longitudinal rotation of the component is not affected by the frame.

[0109] The above solution is only an illustration of a preferred embodiment, but is not limited thereto. When implementing the present invention, appropriate replacement and / or modification can be performed according to user needs.

[0110] The number of devices and processing scales described here are used to simplify the description of the present invention. Applications, modifications and variations of the present invention will be obvious to those skilled in the art.

[0111] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
