[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Example: See Figure 1-Figure 9 An intelligent equipment for laser shaping of ceramic core of aircraft engine blades includes a base 1, a support plate 11 is arranged at the upper end of the base 1, a laser component 12 is arranged on one side of the support plate 11, and a workpiece is processed by the laser component 12. A bottom plate 13 is arranged in the middle position of the upper end of the base 1, and a positioning component 2 is arranged at the upper end of the bottom plate 13. The workpiece is limited by the positioning component 2, and a slider 14 is slidably installed on the upper end of the bottom plate 13.

[0039] In this solution, the laser component 12 is a component that can emit laser, and the material is cut, melted or reconstructed by the laser beam. At the same time, a movable device is set in the inner cavity of the support plate 11, and the movable device can drive the laser component 12 to move and adjust the angle, making it suitable for different scenarios.

[0040] Furthermore, the positioning assembly 2 includes a fixed plate 21 connected to the base plate 13, a sleeve 22 is provided at the middle position of the end of the fixed plate 21, a slide rod 24 is slidably installed on the inner wall of the sleeve 22, and a telescopic member 221 is provided on the outer surface of the sleeve 22, the lower end of the telescopic member 221 is connected to the end of the fixed plate 21, an elastic member 23 is provided in the inner cavity of the sleeve 22, and one end of the elastic member 23 is connected to the slide rod 24, and the other end is connected to the fixed plate 21.

[0041] In this embodiment, the telescopic member 221 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the telescopic member 221 is started, it synchronously drives the sleeve 22 set at the output end of the telescopic member 221 to move, and the sleeve 22 is moved up and down by the sliding rod 24.

[0042] The elastic member 23 is an elastic member such as a spring, and is used to support the slide bar 24 so that the slide bar 24 is always in a buffer state when the slide bar 24 moves.

[0043] Further, multiple groups of push rods 25 are rotatably mounted on the outer surface of the sleeve 22, and the multiple groups of push rods 25 are evenly distributed on the outer surface of the sleeve 22, and at the same time, a movable rod 261 is rotatably mounted on one end of each push rod 25 away from the sleeve 22. A limit block 26 is provided at the upper end of the fixed plate 21 and located on one side of the sleeve 22, and the end of the limit block 26 is rotatably connected to the end of the movable rod 261, and at the same time, a connecting block 262 is rotatably mounted on one end of the movable rod 261 away from the limit block 26.

[0044] Specifically, when the sleeve 22 moves, the push rod 25 installed on the outer surface of the sleeve 22 is synchronously driven to move. Since the movable rod 261 is rotatably installed on the end of the push rod 25 to move, the movable rod 261 rotates around the limit block 26.

[0045] When the movable rod 261 rotates, the connecting block 262 is synchronously driven to rotate, so that the connecting block 262 moves toward the middle.

[0046] Furthermore, an extrusion block 27 is rotatably mounted on the end of the connection block 262, and an arc plate 271 is rotatably mounted on the outer surface of the extrusion block 27; a protective plate 28 is disposed at the upper end of the slide bar 24, and the outer surface of the protective plate 28 is rotatably connected to the end of the extrusion block 27, and a rubber block 29 is disposed at the end of the protective plate 28;

[0047] Specifically, when the connecting block 262 moves, the extrusion block 27 arranged at its end is synchronously driven to move, wherein the extrusion block 27 is rotatably connected to the outer surface of the protective plate 28, so that the connecting block 262 pushes the extrusion block 27 to rotate around the connection with the protective plate 28, so that one side of the extrusion block 27 moves toward the middle, thereby pressing the rubber block 29. The workpiece is limited by the rubber block 29 to ensure that the workpiece can be fixed when placed at any angle, thereby ensuring the stability of subsequent processing.

[0048] The cross section of the rubber block 29 is semicircular, so that the workpiece can be better defined when the workpiece is fixed. The cross section of the extrusion block 27 is arc-shaped, so that it fits the outer surface of the rubber block 29 more closely.

[0049] Furthermore, a positioning plate 211 is disposed at the upper end of the fixing plate 21 , and an inner wall of the upper end of the positioning plate 211 is slidably connected to an outer surface of the sliding rod 24 .

[0050] Specifically, the sliding movement of the slide bar 24 is limited by the positioning plate 211 so that when the slide bar 24 is moved by force, no deviation occurs. At the same time, the protection plate 28 is limited to ensure that the protection plate 28 is always in a stable state.

[0051] When the workpiece needs to be reshaped, the surface of the workpiece is first preliminarily polished by the pretreatment component 3, so as to clean the outer surface of the workpiece and remove oil, oxides, dust and other pollutants on the surface to ensure the smooth progress of subsequent processes; at the same time, the positioning component 2 is used to fix the end of the workpiece, and the end of the workpiece is wrapped by the rubber block 29. When the workpiece is placed in the rubber block 29 at any angle, the workpiece can be fixed by the rubber block 29, thereby reducing the time required for the docking and fixing of the workpiece, and the workpiece will not be damaged due to bumps during assembly.

[0052] Furthermore, the pretreatment component 3 is assembled at the end of the slider 14, and the surface of the workpiece is polished by the pretreatment component 3. The pretreatment component 3 includes a clamping block 31 connected to the slider 14, and a positioning block 33 is provided at the end of the clamping block 31. A limiting rod 331 is provided on the inner wall of the positioning block 33, and a rotating shaft 34 is rotatably installed on the outer surface of the limiting rod 331.

[0053] In this embodiment, the rotation shaft 34 is limited by the positioning block 33 and the limiting rod 331 so that when the rotation shaft 34 rotates, the entirety will not move, thereby ensuring overall stability.

[0054] Furthermore, a driving member 32 is provided at the upper end of the clamping block 31 and at one side of the positioning block 33, and a rotating drum 35 is provided at the output end of the driving member 32. A protrusion 341 is provided on the outer surface of the rotating shaft 34, and a cylinder 36 is slidably mounted on the outer surface of the rotating shaft 34.

[0055] Specifically, the driving member 32 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the driving member 32 is started, it synchronously drives the rotating drum 35 arranged at its output end to move.

[0056] A through hole is formed at the end of the cylinder 36 , and the inner wall of the through hole is slidably engaged with the outer surfaces of the rotating shaft 34 and the protrusion 341 , so that when the cylinder 36 rotates, the rotating shaft 34 is synchronously driven to rotate.

[0057] Furthermore, an arc groove 361 is formed on the outer surface of the cylinder 36 , and blocking blocks 362 are disposed at both ends of the cylinder 36 , and the lower end of the blocking block 362 is rotatably connected to the upper end of the positioning block 33 .

[0058] The inner wall of the rotating drum 35 is provided with a fixing block 351 corresponding to the arc groove 361, and the outer surface of the fixing block 351 is slidably connected to the inner wall of the arc groove 361. The end of the rotating shaft 34 is provided with an air bag 37, and the cross section of the air bag 37 is U-shaped.

[0059] Specifically, when the rotating drum 35 moves upward or downward, the outer surface of the fixing block 351 is slidably connected with the inner wall of the arc-shaped groove 361, and the rotating drum 35 cooperates with the fixing block 351 to drive the cylinder 36 to rotate.

[0060] When the cylinder 36 rotates, it also drives the shaft 34 to rotate, and cooperates with the airbag 37 arranged at its end to wrap the workpiece. At the same time, the outer surface of the airbag 37 is covered with a component with a grinding effect, so as to clean the outer surface of the workpiece and remove oil, oxides, dust and other pollutants on the surface, thereby ensuring the smooth progress of subsequent processes.

[0061] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0062] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
