Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1: Please refer to the appendix of the instruction manual. Figure 1 A multi-station spring assembly device includes an assembly table 1, on which a turntable 2 is rotatably installed; a turntable 3 is rotatably installed inside the assembly table 1 and located to the left of the turntable 2; and a transmission device 7 for driving the turntable 2 and the turntable 3 to rotate. A positioning device 4 is fixedly installed on the top wall of the turntable 3, and a clamping device 5 is fixedly installed on the bottom wall of the turntable 2. Multiple positioning devices 4 and clamping devices 5 are provided, and the multiple positioning devices 4 and clamping devices 5 are distributed in an equal arc state. The number of positioning devices 4 and clamping devices 5 is the same.

[0031] In practical use, the product is transported by the feeding device 6, positioned by multiple positioning devices 4, and clamped by multiple clamping devices 5. The leftmost clamping device 5 assembles the product on the rightmost positioning device 4. After assembly, the transmission device 7 rotates turntable 2 and turntable 3, another clamping device 5 rotates to the leftmost position and another positioning device 4 rotates to the rightmost position, and then the assembly operation is carried out. The assembled product can be disassembled while another group is being assembled, and new products to be assembled can be placed on empty positioning devices 4. There is no need to wait for the assembled product to be disassembled and then clamped before processing, saving time and improving processing efficiency.

[0032] Example 2: Based on Example 1, please refer to the appendix of the instruction manual. Figure 1 , Figure 2 , Figure 4 and Figure 5 The clamping device 5 includes a mounting box 51 fixedly installed on the bottom wall of the turntable 2; a movable box 52 slidably installed inside the mounting box 51, the mounting box 51 and the movable box 52 being mutually compatible; a cylinder 53 fixedly installed on the top wall of the mounting box 51, with the telescopic end of the cylinder 53 movably penetrating through the top wall of the mounting box 51, and the telescopic end of the cylinder 53 being fixedly connected to the top wall of the movable box 52; a cylinder 54 fixedly installed on the top wall inside the cavity of the movable box 52; a movable disc 55 movably installed inside the movable box 52 and fixedly connected to the outer wall of the telescopic end of the cylinder 54; four auxiliary grooves 56 formed on the bottom wall of the movable disc 55, the walls of the four auxiliary grooves 56 being far apart being arc surfaces, and the four auxiliary grooves 56 being distributed in an equal arc state; and a clamping mechanism 57.

[0033] The clamping mechanism 57 includes connecting plates 571 movably installed inside the movable box 52 and corresponding one-to-one with the four auxiliary slots 56, the four connecting plates 571 being distributed in an equal arc state; four positioning clamps 572 respectively fixedly installed on the bottom wall of the four connecting plates 571, the wall surfaces of the four positioning clamps 572 being arc surfaces; four connecting grooves 573 formed on the bottom wall of the movable box 52 and slidably connected to the four connecting plates 571 respectively; four connecting rods 574 respectively fixedly installed inside the four connecting grooves 573 and slidably connected to the four connecting plates 571 respectively; and elastic elements 575 respectively fixedly installed on the wall surfaces of the four connecting grooves 573 and the connecting plates 571 on the same side, the elastic elements 575 being return springs.

[0034] In practical use, the extension end of drive cylinder 53 extends, causing the movable box 52 to move downwards to its lowest position. The extension end of drive cylinder 54 extends, causing the movable disc 55 to move downwards to its lowest position. During this process, the connecting plate 571 moves into the interior of the corresponding auxiliary groove 56. The arc surface of the auxiliary groove 56 contacts the arc surface of the connecting plate 571. The four sets of connecting plates 571 are forced to move closer to each other, the elastic element 575 is compressed, and the four sets of positioning clamping plates 572 move closer to each other to clamp the product on the feeding device 6. Since the four sets of positioning clamping plates 572 move closer to each other, the product can be clamped in the middle position, which can improve the assembly effect. In addition, when the movable disc 55 moves upwards, the four elastic elements 575 begin to extend and return to their original state. The four positioning clamping plates 572, along with the four connecting plates 571, move away from each other and return to their original positions, which is convenient for the next clamping. At the same time, automatic release is achieved, which is convenient for the use of the device.

[0035] Example 3: Based on Example 1, please refer to the appendix of the instruction manual. Figure 1 - Figure 3 The feeding device 6 includes a mounting groove 62 formed on the wall of the assembly table 1 near the clamping device 5; a belt conveyor 61 fixedly installed inside the mounting groove 62, the belt conveyor 61 including a conveyor belt; and a positioning component 63.

[0036] The positioning component 63 includes a positioning post 631 fixedly installed on the upper outer wall of the conveyor belt; and a positioning post 632 fixedly installed on the top wall of the positioning post 631. Multiple positioning posts 631 and positioning posts 632 are provided, and the outer diameter of the positioning post 632 is smaller than that of the positioning post 631.

[0037] The transmission device 7 includes a mounting bracket 74 fixedly installed on the upper side wall of the top of the assembly table 1, the mounting bracket 74 being concave; a second transmission column 73 and a first transmission column 72 rotatably installed on the upper side wall of the top of the assembly table 1 and passing through the top of the assembly table 1, the second transmission column 73 being fixedly connected to the second turntable 3, and the first transmission column 72 being fixedly connected to the first turntable 2; a transmission belt 71 sleeved on the outer wall of the first turntable 2 and the second turntable 3 via pulleys; and a drive motor 75 fixedly installed on the top wall of the mounting bracket 74, the output end of the drive motor 75 being fixedly connected to the second transmission column 73.

[0038] In practical use, the drive motor 75 is turned on, causing the transmission column 73 to rotate. With the cooperation of the transmission belt 71, the transmission column 72 rotates synchronously in the same direction, and the turntables 2 and 3 rotate synchronously in the same direction, causing multiple clamping devices 5 and multiple positioning devices 4 to rotate synchronously. In addition, the rotation of the conveyor belt on the belt conveyor 61 can move the positioning component 63, which facilitates the transportation of products. By setting positioning column 631 and positioning column 632, and the outer diameter of positioning column 632 is smaller than that of positioning column 631, positioning and transportation of products with two different inner diameters can be carried out, thus improving the range of applications.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
