[0030] See also Figure 1 An embodiment of the utility model provides a special-shaped wire saw cutting device based on a motion trajectory, including: a base 10, a wire saw cutting assembly 20 and a cutting platform assembly 30, and the wire saw cutting assembly 20 and the cutting platform assembly 30 are arranged on the base 10.

[0031] See also Figure 2 The wire saw cutting assembly 20 includes a wire saw bracket 21, a wire saw 22 and a power assembly 23. The wire saw bracket 21 is arranged on the base 10, and the wire saw 22 is arranged on the wire saw bracket 21. The power assembly 23 is drivingly connected to the wire saw bracket 21 and is used to drive the wire saw 22 to move up and down, so that the wire saw 22 reciprocates up and down to achieve cutting of the product.

[0032] The structure of the wire saw bracket 21 can be appropriately designed according to actual needs. For example, in some optional embodiments, the wire saw bracket 21 includes two cantilever supports 211 and two cantilever supports 212. The two cantilever supports 211 are arranged side by side on the base 10, and the two cantilever supports 212 are rotatably arranged between the two cantilever supports 211 and are connected to each other. The wire saw 22 is connected between the head ends of the two cantilever supports 212, and the power component 23 is drivingly connected to the cantilever supports 212. Since the two cantilever supports 212 are connected to each other, the power component 23 drives one of the cantilever supports 212 to swing up and down, which can simultaneously drive the two cantilever supports 212 to swing, thereby driving the wire saw 22 to reciprocate up and down. A bearing is installed on the cantilever support 211, and the cantilever bracket 212 and the bearing are rotatably matched. In addition, a reinforcing plate 214 is provided between the two cantilever supports 211, and the reinforcing plate 214 is installed on the cantilever support 211 by screws. The reinforcing plate 214 is used to fill the gap between the two cantilever supports 211 to improve the structural stability of the two cantilever supports 211.

[0033] In some optional embodiments, the tail ends of the two cantilever brackets 212 are connected by an adjusting screw 213, and the adjusting screw 213 is twisted to drive the tail ends of the two cantilever brackets 212 to move closer to or farther from each other, thereby making the head ends of the two cantilever brackets 212 move away from or closer to each other. When the head ends of the two cantilever brackets 212 move away from each other, the wire saw 22 will be tightened, and when the head ends of the two cantilever brackets 212 move closer to each other, the wire saw 22 will be relaxed, thereby adjusting the tension of the wire saw 22. In this embodiment, the distance between the head end of the cantilever bracket 212 and the cantilever support 211 is greater than the distance between the tail end of the cantilever bracket 212 and the cantilever support 211.

[0034] In addition, in this embodiment, a wire saw connecting piece is provided on the cantilever bracket 212, and a bearing is provided on the wire saw connecting piece, which is correspondingly connected to the bushing of the cantilever bracket 212, and the broken arm of the wire saw 22 is locked on the wire saw connecting piece by a threaded piece.

[0035] The structure of the power assembly 23 can be appropriately designed according to actual needs. For example, in some optional embodiments, the power assembly 23 includes a driving motor 231, a mounting seat 232, a motor power arm 233 and a transmission arm 234. The mounting seat 232 is arranged on the base 10. The driving motor 231 is assembled with the mounting seat 232 and is drivingly connected with the motor power arm 233. The two ends of the transmission arm 234 are respectively rotatably connected with the motor power arm 233 and the cantilever bracket 212. The driving motor 231 drives the motor 231 power arm to rotate, and then drives the cantilever bracket 212 to swing up and down through the transmission arm 234. Of course, the power assembly 23 can also adopt other structures, such as replacing the driving motor 231 with an inflatable drill, or the power assembly 23 can also adopt other components that can drive objects to move back and forth, without limiting this example.

[0036] In order to improve stability, in this embodiment, bearings are provided at the connection between the transmission force arm 234 and the cantilever bracket 212 and at the connection between the transmission force arm 234 and the motor power arm 233 .

[0037] See also Figure 3 and Figure 4 The cutting platform assembly 30 includes a supporting platform 31, a cutting platform 32 and a driving mechanism 33. The supporting platform 31 is arranged on one side of the wire saw 22. A track groove 311 is provided on the supporting platform 31. The cutting platform 32 slides with the track groove 311 through a slider 321. The driving mechanism 33 is drivingly connected to the cutting platform 32 and is used to drive the cutting platform 32 to slide along the track groove 311. When the wire saw 22 reciprocates, the driving mechanism 33 drives the cutting platform 32 to move along the set motion trajectory under the guidance of the track groove 311, and the product fixed on the cutting platform 32 moves synchronously under the drive of the cutting platform 32, so that the product is cut by the wire saw 22 according to the motion trajectory specified by the track groove 311, thereby realizing accurate repair of the product, being able to quickly process special-shaped products in small batches, having a simple structure, being easy to use, being able to save working hours, and realizing cost reduction and efficiency improvement.

[0038] In order to facilitate the installation of the slider 321, in some optional embodiments, a slot 322 is provided on the cutting platform 32, and the slider 321 is inserted into the slot 322. In addition, in order to make the movement of the slider 321 more stable and smooth, the slider 321 is cylindrical, and the side curved surface of the slider 321 is slidably matched with the side wall of the track groove 311. Of course, the slider 321 can also be installed in other ways, such as connecting with the cutting platform 32 through a buckle structure, a threaded structure, etc. When the slider 321 is cylindrical, the slider 321 can also rotate with the cutting platform 32, so that the slider 321 rolls along the track groove 311 to reduce friction.

[0039] In some optional embodiments, the track groove 311 is detachably connected to the support platform 31, so as to facilitate the replacement of different track grooves 311 according to the cutting path requirements of different products. In this embodiment, the track groove 311 is detachably mounted on the support platform 31 by screws. Of course, the track groove 311 can also be mounted on the support platform 31 by a buckle structure or a latch structure, etc., without limitation to this example.

[0040] In some optional embodiments, the driving mechanism 33 includes a hand-cranked power arm 331 and a connecting rod mechanism 332. The hand-cranked power arm 331 is rotatably connected to the support platform 31 and is drivingly connected to the cutting platform 32 through the connecting rod mechanism 332. When the wire saw 22 is cutting, the staff shakes the hand-cranked power arm 331, and the hand-cranked power arm 331 drives the cutting platform 32 to move along the track groove 311 through the connecting rod mechanism 332, which is easy to operate. Of course, the driving mechanism 33 can also adopt other suitable structures, not limited to being driven by manpower. For example, the driving mechanism 33 includes a reduction motor and a connecting rod mechanism 332, and the reduction motor drives the support platform 31 to move slowly through the connecting rod mechanism 332. This example is not limited.

[0041] The structure of the connecting rod mechanism 332 can be selected according to actual needs. For example, in some optional embodiments, the connecting rod mechanism 332 includes a first connecting rod 333, a second connecting rod 334 and a third connecting rod 335. The first connecting rod 333 is connected to the hand-cranked power arm 331 by driving, the first connecting rod 333, the second connecting rod 334 and the third connecting rod 335 are connected in rotation in sequence, and the third connecting rod 335 is connected in rotation with the cutting platform 32. The first connecting rod 333 and the second connecting rod 334, the second connecting rod 334 and the third connecting rod 335, and the cutting platform 32 and the third connecting rod 335 are all rotated by pins, and the hand-cranked power arm 331, the first connecting rod 333 and the support platform 31 are also rotated by pins. The connecting rod mechanism 332 can make the hand-cranked power arm 331 suitable for driving the cutting platform 32 to move along different track grooves 311.

[0042] In this embodiment, two connecting parts 336 are provided on the third connecting rod 335 , and both connecting parts 336 are rotatably matched with the cutting platform 32 , thereby improving the stability of the match between the third connecting rod 335 and the cutting platform 32 .

[0043] See also Figure 5In some optional embodiments, two platform supports 11 are provided on the base 10, and a first platform support plate 312 and a second platform support plate 313 are provided at the bottom of the support platform 31. The first platform support plate 312 and the second platform support plate 313 are respectively rotatably cooperated with the two platform supports 11, so that the support platform 31 can rotate relative to the base 10, thereby realizing the angle adjustment of the cutting platform 32, and increasing the range of products that can be adapted for cutting.

[0044] In order to achieve the angle locking between the support platform 31 and the platform support 11, in some optional embodiments, the first platform support plate 312 is provided with an adjustment groove 314 and a threaded locking member 315, the adjustment groove 314 extends along the rotation axis around the first platform support plate 312, the threaded locking member 315 passes through the adjustment groove 314, and then is connected to the platform support 11, and the first platform support plate 312 is locked on the platform support 11 through the threaded locking member 315. When the angle needs to be adjusted, the threaded locking member 315 is loosened, and then the support platform 31 is rotated. When the support platform 31 rotates, the first platform support plate 312 rotates relative to the threaded locking member 315. In this embodiment, the support platform 31 can adjust the angle within the range of -45°-45° relative to the horizontal plane. Of course, by designing the shape of the adjustment groove 314, the angle range that the support platform 31 can adjust can also be increased or decreased. The threaded locking member can be a part with a threaded structure such as a screw or a bolt.

[0045] In this embodiment, the platform support 11 is detachably connected to the base 10 by screws, and the first platform support plate 312 and the second platform support plate 313 are also detachably connected to the support platform 31 by screws, so as to facilitate disassembly and assembly. In addition, a connecting angle piece 316 is provided between the first platform support plate 312 and the support platform 31 and between the second platform support plate 313 and the support platform 31, so as to improve stability.
