[0027] The following will be combined with the drawings of the utility model specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a spring assembly machine with a positioning mechanism, including a base 1, which is the main supporting structure of the entire device, ensuring the stability of the device during operation. A bracket 2 is fixedly connected to the top of the base 1, and a cylinder 3 is fixedly connected to the top of the bracket 2. The cylinder 3 is supported and fixed by the bracket 2, so that the device can be more stable when pushing the spring assembly. A connecting plate 4 is fixedly connected to the output end of the cylinder 3, and an assembly rod 5 is fixedly connected to the middle of the connecting plate 4. The connecting plate 4 is pushed downward by the cylinder 3, so that the assembly rod 5 will also move downward, and then the workpiece 12 is pushed and assembled into the interior of the component by the assembly rod 5. A slide rail 6 is fixedly connected to the bottom of the bracket 2, and a positioning cylinder 7 is fixedly connected to the middle of the slide rail 6. Slide blocks 8 are slidably connected to both sides of the outer periphery of the slide rail 6, and a blocking plate 9 is fixedly connected to the top of the slide block 8. The slide rail 6 is used to fix the positioning cylinder 7 on the one hand, so that the workpiece 12 can be effectively limited inside the positioning cylinder 7, and when the workpiece 12 is pushed out of the device into the interior of the component for assembly, it remains stable. On the other hand, the slide rail 6 can ensure the stable movement between the slider 8 and the blocking plate 9, thereby opening or closing the bottom of the positioning cylinder 7, further limiting the workpiece 12, and facilitating the assembly of the workpiece 12 into the interior of the component at one time.

[0029] Reference Figure 1 , Figure 3 and Figure 4 A connecting rod 10 is arranged between the blocking plate 9 and the connecting plate 4. When the connecting plate 4 and the assembly rod 5 move downward together to assemble the workpiece 12, the assembly rod 5 will synchronously push the blocking plate 9 to move in the opposite or opposite directions through the two connecting rods 10, thereby realizing the opening of the positioning cylinder 7 for assembly, or closing the blocking plate 9 to perform positioning operations on the workpiece 12 that enters the positioning cylinder 7 later. A support frame 13 is fixedly connected to the top edge of the base 1, and a feeding assembly is installed on the top of the support frame 13. The workpiece 12 can be continuously fed into the positioning cylinder 7 for positioning through the feeding assembly, and then assembled. A feed port 15 is installed on the outside of the feeding assembly. The workpiece 12 is neatly arranged inside the feed port 15 through the feeding device, and enters the loading box 14 in turn to wait for loading. A driving assembly is installed on one side of the bottom of the connecting plate 4. The driving assembly can conveniently drive the feeding assembly to operate, which can avoid the need to install additional actuators on the device, reduce the cost of the device, and make the device more concise. A loading port 20 is provided on the outside of the positioning cylinder 7 , and the feeding assembly continuously feeds the workpiece 12 into the positioning cylinder 7 through the loading port 20 for assembly.

[0030] Reference Figure 2-4The top of the connecting rod 10 is hinged to the top of the outer periphery of the assembly rod 5, and the bottom of the connecting rod 10 is hinged to the side of the top of the blocking plate 9 away from the positioning cylinder 7. When the two connecting rods 10 move downward, the two connecting rods 10 push the two blocking plates 9 to move in the opposite direction, open the positioning cylinder 7, and wait for the assembly of the spring. When the two connecting rods 10 move upward, the blocking plates 9 are closed, which is convenient for positioning and guiding the subsequent workpiece 12. The middle side of the top of the base 1 is fixedly connected with an assembly table 11. By placing the component on the assembly table 11, it is convenient for the user to better align the mounting hole of the component with the bottom of the positioning cylinder 7 and directly send the workpiece 12 into the component. The workpiece 12 is installed inside the positioning cylinder 7, and the side close to the two blocking plates 9 passes through the inside of the positioning cylinder 7. When the two blocking plates 9 are driven to open synchronously by the downward assembly rod 5, the assembly rod 5 will also push the workpiece 12 to move downward, and open the blocking plate 9 at the same time. Then the workpiece 12 that has been positioned is directly assembled into the component.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The feeding assembly includes a loading box 14, the bottom of which is fixedly connected to the top of the support frame 13, one side of the loading box 14 is fixedly connected to the outer periphery of the positioning cylinder 7, and the other side of the loading box 14 is fixedly connected to the feeding port 15. A baffle plate 16 is fixedly connected to one side of the interior of the loading box 14, and a push plate 17 is slidably connected to the outer side of the baffle plate 16. A side of the push plate 17 close to the feeding port 15 is fixedly connected to a limiting plate 18. The driving assembly will push the push plate 17 to move in the direction away from the positioning cylinder 7. The inclined surface of the inclined block 22 contacts the top of the push plate 17, so that the inclined block 22 can push the push plate 17 to slide, so that the push plate 17 compresses the compression spring 19, and the limit plate 18 will also move with it, opening the channel between the loading box 14 and the feeding port 15, so that the springs arranged on the feeding port 15 will be pushed into the interior of the loading box 14 by the feeding device, and blocked by the baffle plate 16 to stay near the loading port 20.

[0032] Reference Figure 1 , Figure 2 and Figure 4, a compression spring 19 is arranged on the other side of the inside of the loading box 14, and a notch 23 is provided on the top edge of the loading box 14. The driving assembly includes a fixed rod 21, the top of the fixed rod 21 is fixedly connected to the bottom of the connecting plate 4, and the bottom of the fixed rod 21 is fixedly connected to an inclined block 22, which passes through the notch 23 and is arranged on the side of the push plate 17 close to the positioning cylinder 7. The cylinder 3 drives the assembly rod 5 to move upward, and at this time, the assembly rod 5 moves upward to open the inside of the positioning cylinder 7 and the loading port 20, and at the same time, the inclined block 22 will drive it to be pulled upward from the inside of the notch 23. At this time, the compression spring 19 resets and pushes the push plate 17 and the limit plate 18 to move toward the loading port 20, so that the push plate 17 pushes the spring just fed into the inside of the loading box 14 through the loading port 20 into the inside of the positioning cylinder 7, and stays on the two closed blocking plates 9. At the same time, the limit plate 18 closes the passage between the feed port 15 and the loading box 14 again, and the reciprocating device can realize the process of positioning assembly and automatic loading synchronously with the action of the assembly spring, and the structure is more compact and simple. The outer side of the push plate 17 is slidably connected to the inside of the loading box 14, so that the push plate 17 maintains better stability when it moves. The limit plate 18 is located on the side of the feed port 15 close to the loading box 14, so that after the loading is completed, the inside of the feed port 15 can be closed by the limit plate 18 to prevent excess workpieces 12 from entering the inside of the loading assembly. The loading port 20 is connected to the inside of the loading box 14, so that the workpiece 12 inside the loading box 14 can be pushed by the push plate 17 to pass through the loading port 20 and enter the inside of the positioning cylinder 7. And the loading port 20 is located between the baffle plate 16 and the feed port 15, so that the baffle plate 16 can be directly pushed into the inside of the positioning cylinder 7 by the push plate 17 after the workpiece 12 blocks the limit. One end of the compression spring 19 is fixedly connected to the inner wall of the feeding box 14, and the other end of the compression spring 19 is fixedly connected to the middle of the push plate 17. By continuously compressing and releasing the compression spring 19, the feeding and loading operations are completed.

[0033] Working principle: During assembly, the workpiece 12 is fed into the loading box 14 through the feeding port 15 by the loading device, and the parts are placed on the assembly table 11 at the same time. The cylinder 3 is started to push the connecting plate 4 and the assembly rod 5 downward, so that the assembly rod 5 moves downward to push and compress the workpiece 12 inside the positioning cylinder 7. The positioning cylinder 7 and the blocking plate 9 cooperate to ensure that the workpiece 12 is positioned inside the slide rail 6. After that, as the assembly rod 5 moves downward, the two blocking plates 9 and the slider 8 at the bottom thereof are synchronously pushed to move on the slide rail 6 through the connecting rod 10. The two blocking plates 9 move in the opposite direction and simultaneously leave the positioning cylinder 7. At this time The assembly rod 5 pushes the compressed workpiece 12 downward into the interior of the component to complete the rapid assembly of the spring. At the same time, the connecting plate 4 will push the inclined block 22 through the notch 23 and move downward through the fixed rod 21. The inclined surface of the inclined block 22 contacts the top of the push plate 17, so that the inclined block 22 can push the push plate 17 to slide, so that the push plate 17 compresses the compression spring 19, and the limit plate 18 will also move with it, opening the channel between the loading box 14 and the feeding port 15, so that the springs arranged on the feeding port 15 will be pushed into the loading box 14 by the loading device, and blocked by the blocking plate 16 to stay near the loading port 20. After that, the cylinder 3 drives the assembly rod 5 to move upward. At this time, the assembly rod 5 moves upward to open the space between the inside of the positioning cylinder 7 and the loading port 20, and the inclined block 22 will drive it to be pulled upward from the inside of the notch 23. At this time, the compression spring 19 is reset to push the push plate 17 and the limit plate 18 to move toward the feeding port 20, so that the push plate 17 pushes the spring just fed into the feeding box 14 through the feeding port 20 into the positioning cylinder 7 and stays on the two closed blocking plates 9. At the same time, the limit plate 18 closes the passage between the feeding port 15 and the feeding box 14 again. The reciprocating device can realize the positioning assembly and automatic feeding process synchronously with the action of assembling the spring. The structure is more compact and simple, which reduces the cost of device production and is also convenient for users to maintain in the later stage.
