[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The aviation test cable cutting device starts the motor through an external power supply, and the output end of the motor drives the winding drum to rotate, and the aviation test cable is wound on the surface of the winding drum until the aviation test cable of the appropriate length is wound. The cylinder is started through an external power supply, and the output end of the cylinder drives the cutting knife to move downward, and the aviation test cable placed on the surface of the support table is completely cut by the cutting knife. When the output end of the cylinder moves downward, the driving plate moves downward until the pressure block abuts against the surface of the movable wheel, so that the movable wheel and the fixed rotating wheel clamp and fix the aviation test cable, and as the output end of the cylinder continues to move downward, the driving plate slides horizontally along the surface of the guide rod, and at the same time compresses the support spring, and the elastic force of the support spring after deformation is partially applied to the driving plate and the pressure block, increasing the pressure of the pressure block on the movable wheel, thereby increasing the clamping and fixing effect of the aviation test cable. Prevent the cable from moving a distance to the position of the cutting groove with the cutting force during the cutting process, thereby achieving an effect of inaccurate cutting. After the aviation test cable is cut, the output end of the cylinder moves upward, driving the cutter to move upward. At this time, the support spring gradually rebounds with the movement of the cutter, but still presses the driving plate and the pressure block on the surface of the movable wheel until the support spring returns to its original position. The driving plate and the pressure block continue to move upward with the continued contraction of the output end of the cylinder, so that the pressure block is separated from the surface of the movable wheel, so that the movable wheel and the fixed rotating wheel lose the fixing effect on the aviation test cable, and then the cut end of the aviation test cable is pulled out. The above structure cooperates to achieve the effect of conducting and fixing the cable while reducing the production cost of the device.

[0015] In addition, the aviation test cable cutting device first passes the aviation test cable through the ring and then fixes it to the surface of the reel. While the reel is reeling the aviation test cable, the reciprocating screw rod rotates, and the reciprocating screw rod drives the moving block to move backward first, and after moving to the boundary, the reciprocating screw rod drives the moving block to move forward, and the moving block drives the aviation test cable to guide through the ring, so that the aviation test cable is evenly reeled on the surface of the reel, thereby achieving the effect of evenly winding the cable on the reel.

[0022] When in use, fix the end of the aviation test cable on the reel 202, then start the motor 204 through an external power supply, the output end of the motor 204 drives the reel 202 to rotate, and reel the aviation test cable on the surface of the reel 202 until the aviation test cable of a suitable length is reeled.

[0023] refer to Figure 1 A moving box 205 is fixedly connected to the right side of the support seat 201, and a rotatable reciprocating screw 206 is rotatably connected to the front and rear sides of the inner side of the moving box 205. A moving block 207 is threadedly connected to the surface of the reciprocating screw 206, and a ring 208 is fixedly connected to the top of the moving block 207.

[0024] When in use, first pass the aviation test cable through the ring 208 and then fix it to the surface of the reel 202. While the reel 202 reels the aviation test cable, rotate the reciprocating screw 206. The reciprocating screw 206 drives the moving block 207 to move backward first. After moving to the boundary, the reciprocating screw 206 drives the moving block 207 to move forward. The moving block 207 drives the aviation test cable to guide through the ring 208, so that the aviation test cable is evenly reeled on the surface of the reel 202, preventing the aviation test cable from being reeled in one place of the reel 202.

[0025] Specifically, the output end of the motor 204 and the front end of the reciprocating screw rod 206 are respectively fixedly connected with a synchronous pulley 209, and the outer sides of the two synchronous pulleys 209 are meshed with a transmission belt 210. When the output end of the motor 204 drives the winding drum 202 to rotate, the reciprocating screw rod 206 is driven to rotate through the transmission of the two synchronous pulleys 209 and the transmission belt 210.

[0026] refer to Figure 1 , 2 4. The cutting mechanism 30 includes a cutting box 300 fixedly connected to the top of the base 10, and the left and right sides of the cutting box 300 are respectively provided with through grooves 301, and the front and rear sides of the bottom of the through groove 301 are rotatably connected with fixed wheels 302, and the front and rear sides of the through groove 301 are provided with sliding grooves 303, and the upper and lower sides of the sliding groove 303 are fixedly connected with sliding rods 304, and the sliding rods 304 are slidably connected with sliding blocks 305, and the inner sides of the two sliding blocks 305 on the same side are rotatably connected with movable wheels 306, and the bottom of the sliding block 305 is fixedly connected with a connecting spring 307, and the bottom of the connecting spring 307 is fixedly connected to the sliding groove 303.

[0027] Preferably, the movable wheel 306 and the surface of the fixed rotating wheel 302 are arc-shaped; when not in use, the movable wheel 306 contacts the surface of the fixed rotating wheel 302. When in use, the movable wheel 306 is lifted upward, and the movable wheel 306 drives the sliding block 305 to slide along the surface of the sliding rod 304, and at the same time drives the connecting spring 307 to stretch, and then the aviation test cable is passed through the inner side of the fixed rotating wheel 302 and the movable wheel 306, and then the movable wheel 306 is lowered, so that the connecting spring 307 rebounds and drives the sliding block 305 and the movable wheel 306 to move downward, so that the aviation test cable is clamped between the fixed rotating wheel 302 and the movable wheel 306, and the rotating wheel with an arc surface can contact the cable surface with a larger area, thereby achieving the effect of tensioning the aviation test cable when winding it, making the aviation test cable wound on the winding drum 202 tighter.

[0028] refer to Figure 3 The top of the cutting box 300 is fixedly connected to a cylinder 308, the output end of the cylinder 308 is fixedly connected to a fixed box 309, the bottom of the fixed box 309 is fixedly connected to a cutting knife 314, the bottom side of the cutting box 300 is fixedly connected to a support platform 316, the top of the support platform 316 is provided with a cutting groove 315, and the cutting knife 314 corresponds to the cutting groove 315 in position.

[0029] When in use, the cylinder 308 is started by an external power source, and the output end of the cylinder 308 drives the cutting knife 314 to move downward, so that the aviation test cable placed on the surface of the support platform 316 is completely cut by the cutting knife 314 .

[0030] Further, the left and right sides of the interior of the fixed box 309 are respectively fixedly connected with guide rods 310, the surface of the guide rods 310 is slidably connected with a driving plate 311, the outer bottom of the driving plate 311 is fixedly connected with a pressure block 313, the top of the driving plate 311 is fixedly connected with a support spring 312, and the top of the support spring 312 is fixedly connected with the fixed box 309. When the output end of the cylinder 308 moves downward, the driving plate 311 moves downward until the pressure block 313 abuts against the surface of the movable wheel 306, so that the movable wheel 306 and the fixed rotating wheel 302 clamp and fix the aviation test cable, and as the output end of the cylinder 308 continues to move downward, the driving plate 311 slides horizontally along the surface of the guide rod 310, and the support spring 312 is compressed at the same time, and the elastic force of the support spring 312 after deformation is partially applied to the driving plate 311 and the pressure block 313, increasing the pressure of the pressure block 313 on the movable wheel 306, thereby increasing the clamping and fixing effect of the aviation test cable. This prevents the cable from moving a distance toward the position of the cutting groove 315 due to the cutting force during the cutting process, thereby achieving an inaccurate cutting effect. After the aviation test cable is cut, the output end of the cylinder 308 moves upward, driving the cutting blade 314 to move upward. At this time, the support spring 312 gradually rebounds with the movement of the cutting blade 314, but still presses the driving plate 311 and the pressing block 313 on the surface of the movable wheel 306 until the support spring 312 returns to its original position. The driving plate 311 and the pressing block 313 will continue to move upward with the storage of the output end of the cylinder 308 and will be separated from the surface of the movable wheel 306, so that the cut end of the aviation test cable can be pulled out after cutting.

[0031] Preferably, the bottom surface of the pressing block 313 is in the same shape as the end of the movable wheel 306 , so that the pressing block 313 can better contact the surface of the movable wheel 306 , thereby enhancing the pressing effect.

[0032] The working principle of the utility model is: the motor 204 is started by an external power supply, and the output end of the motor 204 drives the reel 202 to rotate, and the aviation test cable is reeled on the surface of the reel 202 until the aviation test cable of a suitable length is reeled. The cylinder 308 is started by an external power supply, and the output end of the cylinder 308 drives the cutting knife 314 to move downward, and the aviation test cable placed on the surface of the support platform 316 is completely cut by the cutting knife 314. When the output end of the cylinder 308 moves downward, the driving plate 311 moves downward until the pressing block 313 contacts the surface of the movable wheel 306, so that the movable wheel 306 and the fixed rotating wheel 302 clamp and fix the aviation test cable. As the output end of the cylinder 308 continues to move downward, the driving plate 311 slides horizontally along the surface of the guide rod 310, and the support spring 312 is compressed. The elastic force of the support spring 312 after deformation is partially applied to the driving plate 311 and the pressing block 313, increasing the pressure of the pressing block 313 on the movable wheel 306, thereby increasing the clamping and fixing effect of the aviation test cable. Prevent the cable from moving a distance to the position of the cutting groove 315 with the cutting force during the cutting process, thereby achieving an effect of inaccurate cutting. After the aviation test cable is cut, the output end of the cylinder 308 moves upward, driving the cutting knife 314 to move upward. At this time, the support spring 312 gradually rebounds with the movement of the cutting knife 314, but still presses the driving plate 311 and the pressure block 313 on the surface of the movable wheel 306 until the support spring 312 returns to its original position. The driving plate 311 and the pressure block 313 move upward with the continued contraction of the output end of the cylinder 308, so that the pressure block 311 is separated from the surface of the movable wheel 306, so that the movable wheel 306 and the fixed rotating wheel 302 lose their fixing effect on the aviation test cable, and then the cut end of the aviation test cable is pulled out.
