Figure 2 It is a partial structural schematic diagram of the first embodiment of the utility model. Figure 3 It is a partial structural stereogram of the first embodiment of the utility model.

[0022] The utility model provides a trimming die for aircraft titanium alloy inlaid cup-shaped parts, comprising a workbench 101, an L-shaped plate 102, a hydraulic cylinder 103 and an adjusting component, wherein the adjusting component comprises a connecting seat 104, a trimming device 105, a chassis 106, a driving member, a fixed disk 107 and four groups of fixing members, wherein the driving member comprises a carrier frame 108, a driving motor 109 and a rotating disk 110, and each group of the fixing members comprises a sliding rod 111, a sliding seat 112, a telescopic rod 113 and a spring 114, a fixed seat 115 and a supporting plate 116. The above-mentioned scheme solves the problem that the mold cannot perform fixed trimming on cup-shaped parts of different sizes, resulting in the need to replace the mold when the size of the cup-shaped part changes, thereby reducing the convenience and practicality of the equipment.

[0023] According to the present specific embodiment, the L-shaped plate 102 is fixedly connected to the workbench 101 and is located above the workbench 101. The hydraulic cylinder 103 is fixedly connected to the L-shaped plate 102 and passes through the L-shaped plate 102. The adjustment assembly includes a connecting seat 104, a trimming device 105, a chassis 106, a driving member, a fixed plate 107 and four groups of fixing members. The connecting seat 104 is fixedly connected to the output end of the hydraulic cylinder 103 and is located below the L-shaped plate 102. The trimming device 105 is detachably connected to the connecting seat 104 and is located below the connecting seat 104. The chassis 106 is fixedly connected to the workbench 101 and is located above the workbench 101. The driving member is fixedly connected to the workbench 101 and is located on the outside of the workbench 101. The fixed plate 107 is fixedly connected to the chassis 106 and is located above the chassis 106. The four groups of fixing parts are distributed circumferentially along the axial center line of the fixed plate 107. The fixing parts are slidably connected to the fixed plate 107 and are located above the fixed plate 107. The L-shaped plate 102 fixes the hydraulic cylinder 103. The chassis 106 carries the fixed plate 107. The trimming device 105 adapted to the cup-shaped part is installed below the connecting seat 104. The cup-shaped part is placed above the fixed plate 107. The driving part drives the fixing part to operate. The fixing part moves outward to fix the cup-shaped part. The hydraulic cylinder 103 pushes the trimming device 105 downward to perform trimming operations on the cup-shaped part. This method can effectively solve the problem that the mold cannot perform fixed trimming on cup-shaped parts of different sizes.

[0024] Among them, the supporting frame 108 is fixedly connected to the workbench 101 and is located below the workbench 101, the output end of the driving motor 109 is fixedly connected to the rotating disk 110 and is located above the supporting frame 108, the rotating disk 110 is rotatably connected to the chassis 106 and is located above the chassis 106, the supporting frame 108 fixes the driving motor 109, and the driving motor 109 drives the rotating disk 110 to rotate above the chassis 106, thereby driving the fixed part to move.

[0025] Secondly, the sliding rod 111 is slidably connected to the rotating disk 110 and is located inside the rotating disk 110. The sliding seat 112 is fixedly connected to the sliding rod 111 and is located below the sliding rod 111. The telescopic rod 113 is fixedly connected to the sliding seat 112 and is located on the outside of the sliding seat 112. The spring 114 is arranged on the outside of the telescopic rod 113. The sliding rod 111 slides inside the rotating disk 110, driving the sliding seat 112 to slide outward. The telescopic rod 113 and the spring 114 are compressed when they are against the cup-shaped piece, so as to prevent the cup-shaped piece from being over-fixed and causing damage to the surface of the cup-shaped piece.

[0026] At the same time, the fixed seat 115 is fixedly connected to the telescopic rod 113 and is located on the outside of the telescopic rod 113. The fixed seat 115 is rotatably connected to the supporting plate 116 and is located on the outside of the fixed seat 115. The supporting plate 116 fits the cup-shaped part. The fixed seat 115 is rotatably connected to the supporting plate 116 so that the supporting plate 116 completely fits the curved surface of the cup-shaped part, thereby fixing the cup-shaped part more firmly and preventing it from moving during trimming operations.

[0027] In addition, the fixed disk 107 has a sliding groove 117 adapted to the sliding seat 112, and the rotating disk 110 has an arc groove 118 adapted to the sliding rod 111. The sliding rod 111 slides in the arc groove 118 and drives the sliding seat 112 to slide in the sliding groove 117, thereby limiting the running trajectories of the sliding rod 111 and the sliding seat 112, preventing deviation during operation, and improving the stability of the equipment during operation.

[0028] The trimming die of the aircraft titanium alloy inlaid cup-shaped piece of the present embodiment is used. By setting an L-shaped plate 102, a hydraulic cylinder 103 and an adjusting component, when it is used, the trimming device 105 adapted to the cup-shaped piece is installed below the connecting seat 104, and the cup-shaped piece is placed above the fixed plate 107. The driving motor 109 drives the rotating plate 110 to rotate above the chassis 106, and the sliding rod 111 slides in the rotating plate 110, driving the sliding seat 112 to slide outward. The supporting plate 116 touches the inner wall of the cup-shaped part, and the telescopic rod 113 and the spring 114 are continuously compressed so that the supporting plate 116 completely fits the curved surface of the cup-shaped part to fix the cup-shaped parts of different sizes. The hydraulic cylinder 103 pushes the trimming device 105 downward to perform trimming operations on the cup-shaped part, so that the mold can fix the cup-shaped parts of different sizes. The detachable trimming device 105 is convenient for trimming the cup-shaped parts of different sizes, thereby improving the convenience and practicality of the equipment.

[0029] The second embodiment of the present application is:

[0030] Based on the first embodiment, please refer to Figure 4 , Figure 4 It is a structural schematic diagram of the second embodiment of the utility model.

[0031] The utility model provides a trimming die for an aircraft titanium alloy inlaid cup-shaped part, which also includes four groups of protective components. The four groups of protective components are distributed around the axial center line of the fixed disk 107 , and each group of protective components includes a Velcro 201 and a soft pad 202 .

[0032] According to this specific embodiment, the Velcro 201 is fixedly connected to the supporting plate 116 and is located on the outside of the supporting plate 116. The soft pad 202 is detachably connected to the Velcro 201 and is located on the outside of the Velcro 201. The soft pad 202 is installed on the outside of the supporting plate 116 through the Velcro 201, which facilitates the replacement of the soft pad 202. The soft pad 202 is in contact with the cup-shaped part to protect the surface of the cup-shaped part from damage to the greatest extent.

[0033] A trimming die for an aircraft titanium alloy inlaid cup-shaped part using the present embodiment is provided with four sets of protective components. When it is used, the soft pad 202 is installed on the outer side of the supporting plate 116 via the Velcro 201, so that the soft pad 202 can be easily replaced. The soft pad 202 is in contact with the cup-shaped part to protect the surface of the cup-shaped part from damage to the greatest extent, thereby improving the protective effect of the cup-shaped part and improving the operation quality of the equipment.
