[0017] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0018] Figure 1 It is a structural diagram of the present utility model.

[0019] As attached Figure 1As shown, a spring driving and tightening mechanism includes a base plate 1, a linear moving mechanism 2, a spring driving mechanism 3, a discharge nozzle 4, a discharge nozzle opening and closing mechanism 5, a floating rotary head 6, and a rotary head rotating mechanism 7. The linear moving mechanism 2 is installed on the base plate 1, the spring driving mechanism 3 and the rotary head rotating mechanism 7 are installed on the moving part of the linear moving mechanism 2, the floating rotary head 6 is connected to the rotating part of the rotary head rotating mechanism 7, and the spring driving mechanism 3 is provided with a discharge nozzle 4 and a discharge nozzle opening and closing mechanism 5.

[0020] The linear motion mechanism 2 includes a power cylinder 21 and a sliding table 22. The sliding table 22 is slidably connected to the straight rail of the base plate 1. The cylinder body and piston rod of the power cylinder 21 are respectively connected to the sliding table 22 and the base plate 1. The spring driving mechanism 3 and the rotary head rotating mechanism 7 are both installed on the sliding table 22.

[0021] The piston rod of the power cylinder 21 can be extended and retracted to drive the sliding platform 22 to move linearly along the straight rail.

[0022] The spring driving mechanism 3 includes a single-rod power cylinder 31, a material box 32, and a feed pipe 33. The cylinder body of the single-rod power cylinder 31 is fixed on the sliding table 22. A horizontal flow channel is provided in the material box 32. The piston rod of the single-rod power cylinder 31 is placed in the horizontal flow channel. A discharge nozzle 4 is provided at the front end of the material box 32. The discharge nozzle 4 is connected to the horizontal flow channel. A feed pipe 33 is provided at the top of the material box 32, and the feed pipe 33 is connected to the horizontal flow channel of the material box 32.

[0023] The springs slide from the feed pipe 33 into the horizontal flow channel of the material box 32 in sequence. At this time, the horizontal springs are placed between the discharge nozzle 4 and the piston rod of the single-rod power cylinder 31. Then the single-rod power cylinder 31 drives the piston rod to push the spring forward until it is pushed out of the discharge nozzle 4.

[0024] The discharge nozzle opening and closing mechanism 5 includes a lifting cylinder 51 and a shift rod 52 . The shift rod 52 is fixed to the piston rod of the lifting cylinder 51 , and a through hole for the shift rod 52 to pass through is provided on the pipe wall of the discharge nozzle 4 .

[0025] The piston rod of the lifting cylinder 51 drives the lever 52 to move up, so that the passage of the discharge nozzle 4 is opened, so that the spring can pass through the discharge nozzle 4. When the lever 52 moves down and blocks the passage of the discharge nozzle 4, the spring in the material box 32 just cannot move into the discharge nozzle 4.

[0026] The floating rotary head 6 includes a rotary head 61, a spring 62, and a tube body 63. The tail rod of the rotary head 61 is slidably connected in the tube body 63. A spring 62 is connected between the rotary head 61 and the tube body 63. The tube body 63 is rotatably connected to the sliding platform 22 through a support seat.

[0027] After the floating rotary head 6 presses against the spring, the floating rotary head 6 will retreat along the tube body 63 and a buffering force will be applied by the spring 62 .

[0028] The rotary head rotating mechanism 7 includes a motor and a reducer. The output shaft of the motor is connected to the reducer, and the output shaft of the reducer is fixed on the tube body 63.

[0029] A buffer 8 is installed on the base plate 1 to provide buffering for the sliding platform 22 .

[0030] The working method of the present application is that the springs in the vibrating disk are sequentially fed into the horizontal channel of the material box 32, and then the piston rod of the linear motion mechanism 2 extends and drives the sliding table 22 to move forward until the discharge nozzle 4 reaches the end face of the product workpiece. The discharge nozzle opening and closing mechanism 5 opens the channel of the discharge nozzle 4, the spring driving mechanism 3 pushes the spring out of the discharge nozzle 4 and drives it into the rotor hole, and the piston rod of the linear motion mechanism 2 retracts. The workpiece moves to the front of the floating rotary head 6, and then the linear motion mechanism 2 drives the floating rotary head 6 to move forward. After the floating rotary head 6 presses against the spring in the workpiece, the rotary head rotation mechanism 7 drives the rotating floating rotary head 6 to rotate, and the floating rotary head 6 drives the spring to rotate back into the rotor hole and fit tightly, and the piston rod of the linear motion mechanism 2 retracts, thereby completing the assembly of the product workpiece.

[0031] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
