[0027] For this specific embodiment, the second motor 115 is started to drive the rotating shaft 116 to rotate, so that the rotating disc 117 rotates, thereby driving the rotating shell 102 to rotate, and driving the cutter 109 to rotate, so that the cutter 109 is used to perform forming processing on the spring 112 workpiece, while the pressure sensor 108 detects that the pressure is too small, which means that the cutter 109 does not fully contact the workpiece, at this time, the first motor 104 is started to drive the threaded rod 105 to rotate, which cooperates with the threaded hole 111 to drive the compensation moving block 106 to extend out of the rotating shell 102, while the through hole 114 of the compensation moving block 106 moves along the limiting rod 113, thereby improving the stability of movement, so as to move the cutter 109 close to the workpiece to compensate for the error.

[0028] The rotating unit is arranged on the base 101, the rotating shell 102 is arranged on the rotating unit, the fixed block 103 is fixedly connected with the rotating shell 102 and located in the interior of the rotating shell 102, the fixed block 103 has a groove 110, the first motor 104 is fixedly connected with the fixed block 103 and located in the interior of the groove 110, the compensation moving block 106 has a threaded hole 111, one end of the threaded rod 105 is adapted to the threaded hole 111, the other end of the threaded rod 105 penetrates through the fixed block 103 and is fixedly connected with the output end of the first motor 104, the threaded rod 105 is rotationally connected with the fixed block 103, the two ends of the support rod 107 are fixedly connected with the compensation moving block 106 and the pressure sensor 108 respectively, and the cutter 109 is arranged on the pressure sensor 108 through the cutter 109 mounting unit. The rotating unit is started to drive the rotating shell 102 to rotate, thereby relying on the cutter 109 to perform forming processing on the spring 112 workpiece, while the pressure sensor 108 detects that the pressure is too small, which means that the cutter 109 does not fully contact the workpiece, at this time, the first motor 104 is started to drive the threaded rod 105 to rotate, which cooperates with the threaded hole 111 to drive the compensation moving block 106 to extend out of the rotating shell 102, thereby moving the cutter 109 close to the workpiece to compensate for the error, so that the small error between the cutter 109 and the workpiece can be compensated for automatically without manual adjustment, so that the cutter 109 and the workpiece are in good contact, and the forming quality of the spring 112 is improved.

[0029] Secondly, two ends of the spring 112 are movably connected with the fixed block 103 and the compensation moving block 106 respectively, and the spring 112 is sleeved outside the threaded rod 105. When the compensation moving block 106 moves, the spring 112 also rebounds, and under the joint action of the spring 112 and the threaded rod 105, the compensation moving block 106 is driven to move out of the rotating shell 102.

[0030] Meanwhile, the compensation moving block 106 also has two through holes 114, one end of two limiting rods 113 is fixedly connected with the fixed block 103 and is symmetrically distributed on both sides of the threaded rod 105, and the other end of the two limiting rods 113 is respectively matched with the corresponding through hole 114. When the compensation moving block 106 moves, the through hole 114 of the compensation moving block 106 moves along the limiting rod 113, thereby improving the moving stability.

[0031] In addition, the second motor 115 is fixedly connected with the base 101 and located on one side of the base 101, the rotating disc 117 is rotatably connected with the base 101 and located on the side of the base 101 away from the second motor 115, one end of the rotating shaft 116 is fixedly connected with the output end of the second motor 115, the other end of the rotating shaft 116 penetrates through the base 101 and is fixedly connected with the rotating disc 117, and the rotating shell 102 is fixedly connected with the rotating disc 117 and located on one side of the rotating disc 117. The base 101 supports the second motor 115, the second motor 115 is started to drive the rotating shaft 116 to rotate, so that the rotating disc 117 rotates, thereby making the rotating shell 102 rotate to drive the cutter 109 to rotate and perform forming machining.

[0033] When the spring forming cutter positioning error compensation device of the embodiment is used, the second motor 115 is started to drive the rotating shaft 116 to rotate, so that the rotating disc 117 rotates, thereby driving the rotating shell 102 to rotate and driving the cutter 109 to rotate, so that the cutter 109 performs forming machining on the spring 112 workpiece. At the same time, the pressure sensor 108 detects that the pressure is too small, which means that the cutter 109 does not fully contact the workpiece. At this time, the first motor 104 is started to drive the threaded rod 105 to rotate, which cooperates with the threaded hole 111 to drive the compensation moving block 106 to extend out of the rotating shell 102. At the same time, the through hole 114 of the compensation moving block 106 moves along the limiting rod 113, thereby improving the moving stability to move the cutter 109 close to the workpiece to compensate for the error. When the pressure sensor 108 detects that the pressure is too large, which means that the cutter 109 is too close to the workpiece. At this time, the output end of the first motor 104 counterclockwise rotates to drive the threaded rod 105 to rotate, which cooperates with the threaded hole 111 to drive the compensation moving block 106 to move towards the inside of the rotating shell 102, so that the cutter 109 moves away from the workpiece until the pressure value of the pressure sensor 108 returns to normal. Through the above structure, the small error between the cutter 109 and the workpiece can be compensated automatically without manual adjustment, so that the cutter 109 and the workpiece are in good contact, and the spring 112 forming quality is improved.
