The winding shaft 10 is then connected and fixed to the drive shaft 5 through the connecting component 11. Then the feeding component 12 starts working, controlling the stable discharge of the steel wire to ensure that the steel wire can be accurately wound on the winding shaft 10. After that, the first drive motor 4 is turned on, and the drive shaft 5 at its output end drives the winding shaft 10 to rotate. At the same time, the drive component 3 is turned on to control the installation plate 2 to translate, and the spring can be wound.

[0026] A mounting groove 8 is provided inside the turntable 7 . A plurality of mounting grooves 8 are provided in a ring shape inside the turntable 7 . A bearing 9 is fixedly installed inside the mounting groove 8 , and a winding shaft 10 is fixedly installed in the inner ring of the bearing 9 .

Under the elastic force of the first spring 1106, the sleeve 1101 moves forward and the limit block 1102 is embedded in the limit groove 1103 to achieve axial positioning of the winding shaft 10 and the driving shaft 5.

[0030] The driving assembly 3 includes a second driving motor 301, a first slide groove 302, a first slide rod 303, a screw rod 304 and a slider 305.

[0031] When the second drive motor 301 is started, it drives the screw rod 304 to rotate, so that the mounting plate 2 can achieve smooth translational motion on the base plate 1. Then, according to the instructions of the CNC system, the translational speed and distance of the mounting plate 2 are precisely controlled to meet the requirements for the axial position change of the winding shaft 10 during different spring winding processes, thereby ensuring that the wound spring meets the preset shape and size.

[0032] The feeding assembly 12 includes a mounting block 1201, a support block 1202, a mounting frame 1203, a cam 1204, a gear 1205, a third drive motor 1206 and a discharge pipe 1207. The mounting block 1201 is slidably mounted on the top of the base plate 1, the support block 1202 is fixedly connected to the top of the mounting block 1201, the mounting frame 1203 is fixedly connected to the top of the support block 1202, the cam 1204 has multiple symmetrical mountings inside the mounting frame 1203, the gear 1205 has two bottoms of two symmetrical cams 1204 fixedly connected to the front end in sequence, the third drive motor 1206 is fixedly mounted inside the limit block 1102, and the bottom of one of the gears 1205 is fixedly mounted on the output end of the third drive motor 1206, the discharge pipe 1207 is fixedly connected to the top of the mounting block 1201 and is located at the discharge end of the cam 1204, and the discharge end of the discharge pipe 1207 is aligned with the winding shaft 10.

[0033] When in use, the CNC system controls the third drive motor 1206 to start, driving the gear 1205 connected to it to rotate. Since the two gears 1205 are engaged with each other, the two front end cams 1204 rotate at the same time, and then the steel wire is installed between the two cams 1204. The steel wire is transported under the friction force of the cams 1204 and enters the discharge pipe 1207. The discharge end of the discharge pipe 1207 is aligned with the winding shaft 10 to ensure that the steel wire can be accurately delivered from the discharge pipe 1207 and wound on the winding shaft 10, thereby achieving a stable feeding process and ensuring the quality of the wound spring.

[0034] The feeding assembly 12 also includes an electric push rod 1208 and a cutting knife 1209. The electric push rod 1208 is fixedly mounted on the top of the mounting block 1201, and the cutting knife 1209 is fixedly mounted on the top of the electric push rod 1208 and fits with the output port of the discharge pipe 1207.

[0035] After the spring is wound, the numerical control system controls the electric push rod 1208 to start, and the electric push rod 1208 pushes the cutting knife 1209 to move upward. The cutting knife 1209 contacts the steel wire at the output port of the discharge pipe 1207 and cuts it.

[0036] The bottom of the mounting block 1201 is fixedly connected to a moving block 1210, a second sliding groove 1211 is provided on the top of the base plate 1, the moving block 1210 is located inside the second sliding groove 1211, a second sliding rod 1212 is fixedly connected inside the second sliding groove 1211, there are two second sliding rods 1212, the outer wall of the second sliding rod 1212 is sleeved with a second spring 1213, and a sliding hole corresponding to the second sliding rod 1212 is provided inside the moving block 1210.

[0037] When the required winding shaft 10 needs to be replaced before use, the installation block 1201 can be pushed to slide to prevent the position of the installation block 1201 from affecting the rotation of the turntable 7.

[0038] The outer wall of the bottom plate 1 is fixedly connected with ear plates 101 . There are four ear plates 101 , and the four ear plates 101 are distributed in a rectangular shape.

[0039] By providing mounting holes and other structures on the ear plate 101, the entire spring winding machine can be firmly mounted on a work platform or other supporting structure, ensuring the stability of the equipment during operation, reducing errors caused by equipment shaking, and ensuring the accuracy and quality of spring winding.

[0040] Working principle: First, all drive sources are controlled by CNC, which precisely controls each drive motor and other actuators through preset programs.

[0041] When in use, first rotate the turntable 7, which can rotate around the front end of the support shaft 6, move the winding shaft 10 of the required size to the position corresponding to the drive shaft 5, then push the sleeve 1101 backward to squeeze the first spring 1106, then align the limit block 1102 with the limit groove 1103, and then release the sleeve 1101. Under the elastic force of the first spring 1106, the sleeve 1101 moves forward and the limit block 1102 is embedded in the limit groove 1103 to achieve axial positioning of the winding shaft 10 and the drive shaft 5.

[0042] Next, the third drive motor 1206 is controlled to start, driving the gear 1205 connected to it to rotate. Since the two gears 1205 are engaged with each other, the two front end cams 1204 rotate at the same time. Then the steel wire is installed between the two cams 1204. The steel wire is transported under the friction force of the cams 1204 and enters the discharge pipe 1207. The discharge end of the discharge pipe 1207 is aligned with the winding shaft 10 to ensure that the steel wire can be accurately delivered from the discharge pipe 1207 and wound on the winding shaft 10.

[0043] Then, when the second drive motor 301 is started, it drives the screw rod 304 to rotate, so that the mounting plate 2 can achieve smooth translational movement on the base plate 1. Then, according to the instructions of the CNC system, the translation speed and distance of the mounting plate 2 are precisely controlled to meet the requirements for the axial position change of the winding shaft 10 during different spring winding processes, thereby ensuring that the wound spring meets the preset shape and size.

[0044] Afterwards, the first drive motor 4 is turned on, and the drive shaft 5 at its output end drives the winding shaft 10 to rotate, thereby winding the spring.

[0045] After the spring is wound, the numerical control system controls the electric push rod 1208 to start, and the electric push rod 1208 pushes the cutting knife 1209 to move upward. The cutting knife 1209 contacts the steel wire at the output port of the discharge pipe 1207 and cuts it.
