[0044] refer to Figure 5 , Figure 6 , the pre-installed plate 401 is provided with a plurality of pre-installed holes 16, and the pre-installed holes 16 penetrate the pre-installed plate 401. A limiting groove 40 is provided on the side wall of the pre-installed plate 401, and a limiting plate 402 is slidably arranged in the limiting groove 40. The limiting plate 402 is provided with a plurality of limiting holes 15, and the number of limiting holes 15 corresponds to the number of pre-installed holes 16. Among them, before the spring is loaded into the pre-installed product, the plurality of pre-installed holes 16 and the plurality of limiting holes 15 are arranged in a staggered position. When the pre-installed plate 401 cooperates with the pressing mechanism 5 to load the spring into the pre-installed product, the plurality of pre-installed holes 16 and the plurality of limiting holes 15 are arranged in a corresponding position.

[0045] refer to Figure 3 , Figure 5 A clearance groove 42 is provided on the side wall of the pre-installed plate 401, and the inner wall of the clearance groove 42 is fixedly connected to the limit cylinder 14. The end of the piston rod of the limit cylinder 14 is fixedly connected to the limit plate 402. The limit plate 402 is driven to slide in the limit groove 40 by the limit rod 14, so that the positions of the pre-installed hole 16 and the limit hole 15 are relative or staggered.

[0046] The upper end surface of the workbench 1 is fixedly connected with a boss 17, and the position of the boss 17 is higher than the position of the pre-installed plate 401. The pressing mechanism includes a pressing slide 18 fixedly connected to the upper end surface of the boss 17, and a sliding plate 19 is slidably connected to the pressing slide 18, and the sliding plate 19 slides toward the pre-installed plate 401.

When working, the press pins 502 are extended into the pre-installed holes 16 under the drive of the press cylinder 20.

[0048] The push-in ejector pin 502 penetrates the push-in plate 501, and a ventilation hole 41 axially penetrates the push-in ejector pin 502. An air blowing device is provided at one end of the push-in ejector pin 502 away from the pre-installed plate 401. The air blowing device cooperates with the ventilation hole 41 to blow the spring in the pre-installed hole 16 into the pre-installed product.

[0049] The working process of Example 1 in the present application is as follows: the spring in the vibration plate 301 enters the corresponding material limiting hole 8 on the material storage block 303 through the material guide tube 302, and the material limiting cylinder 11 drives the material limiting ejector pin 701 to extend into the material limiting hole 8, so that the spring in the material limiting hole 8 cannot fall directly into the material receiving plate 6012.

[0050] When the spring needs to be delivered, the limiting cylinder 11 drives the limiting ejector pin 701 to extend out of the limiting hole 8, so that the spring falls into the receiving hole 29. The receiving cylinder 22 drives the receiving plate 6012 to slide toward the rotating table 21, so that after the receiving plate 6012 moves out of the receiving table 6011, the spring is sleeved on the rotating rod 31 on the receiving plate 6012 by free fall. After the spring is sleeved on the rotating rod 31, the receiving cylinder 22 drives the receiving plate 6012 to reset.

[0051] The feeding slide 6022 moves along the feeding slide rail 6021 to drive the clamping cylinder 34 to move toward the transfer table 21, so that the clamping claw 35 on the clamping claw cylinder 34 is located above the transfer table 21, and further makes the clamping hole 36 on the clamping claw 35 correspond to the position of the transfer rod 31.

[0052] By driving the feeding cylinder 23, the clamping claw 35 is moved closer to the rotating table 21. At the same time, the protection cylinder 37 drives the protection plate 38 to move closer to the rotating table 21, so that the protection ejector pin 39 is inserted into the spring to ensure that the spring will not be deformed during the clamping process. After the clamping claw 35 approaches the clamping position, the spring of the tea oil protection ejector pin 39 is clamped by the clamping claw cylinder 34.

[0053] The feeding cylinder 23 is driven to lift the feeding plate 33, so that the clamping claw 35 is away from the transfer trough 30. Then the feeding slide 6022 is driven to slide along the side close to the pre-installed plate 401, so that the clamping claw 35 is located above the pre-installed plate 401, and the clamping hole 36 corresponds to the pre-installed hole 16.

[0054] When the clamping hole 36 corresponds to the pre-installed hole 16 , the feeding cylinder 23 is driven to make the clamping claw 35 approach the pre-installed hole 16 so that the spring part extends into the pre-installed hole 16 , and then the clamping claw cylinder 34 releases the spring so that the spring falls into the pre-installed hole 16 .

[0055] After the spring falls into the pre-installed hole 16, the feeding slide 6022 and the feeding cylinder 23 are driven to reset the clamp 35 so as to clamp the newly unloaded spring received by the receiving plate 6012 on the rotating table 21 and transported to the storage block 303 on the rotating table 21.

[0056] Before the spring falls into the pre-installed hole 16, the limiting cylinder 14 is driven to make the limiting plate 402 slide in the limiting groove 40, so that the limiting hole 15 on the limiting plate 402 is misaligned with the pre-installed hole 16, thereby preventing the spring from falling directly onto the feed track 2 when falling into the pre-installed hole 16.

[0057] And in the process of the spring clamp moving to the pre-installed plate 401, the pre-installed product moves along the feed track 2 to the bottom of the pre-installed plate 401, and the pre-installed cylinder 12 drives the pre-installed plate 401 to approach the pre-installed product, and makes the installation groove on the pre-installed product correspond to the position of the pre-installed hole 16.

[0058] The pressing slide 18 drives the sliding plate 19 to slide toward the pre-installed plate 401, further causing the pressing plate 501 on the pressing cylinder 20 to move toward the pre-installed plate 401. When the pressing ejector pin 502 corresponds to the position of the pre-installed hole 16, the sliding plate 19 stops sliding.

[0059] The pressing cylinder 20 is driven to move the pressing plate 501 close to the pre-installed plate 401, and further the pressing ejector pin 502 is extended into the pre-installed hole 16. At the same time, the limiting cylinder 14 is driven to make the limiting hole 15 correspond to the position of the pre-installed hole 16, so that the spring falls into the installation groove of the pre-installed product. The pressing ejector pin 502 further extends into the pre-installed hole 16, penetrates the pre-installed plate 401 and extends into the pre-installed product, thereby pressing and fixing the spring in the pre-installed product. At this time, the spring is further installed in place on the pre-installed product through the blowing device.

[0060] After the spring is installed, the pressing cylinder 20 is driven to reset the pressing ejector 502 , and the pressing slide 18 is driven to move the sliding plate 19 away from the pre-installed plate 401 to facilitate the installation of the next spring into the pre-installed hole 16 .

[0061] In addition, after the pre-installed product is installed, the feed track 2 drives the pre-installed product to move so that the installed pre-installed product removes the pre-installed plate 401, and the uninstalled pre-installed product moves to the bottom of the pre-installed plate 401, so that the spring installation groove on the pre-installed product corresponds to the position of the pre-installed hole 16.

[0062] Embodiment 2: refer to Figure 7 , Figure 8 , Fig. 9 , a spring automatic installation machine, whose structure differs from that of Example 1 in that the transportation mechanism includes a hanging rail 24 arranged above the workbench 1, and the hanging rail 24 is slidably connected to an electric slide 25 on the side close to the workbench 1, and the electric slide 25 is fixedly connected to a rotating structure 26 on the side close to the workbench 1.

[0063] The rotating rod of the rotating structure 26 is arranged toward the side close to the workbench 1 , and the end of the rotating rod of the rotating structure 26 is fixedly connected to a telescopic cylinder 27 .

[0064] The piston rod of the telescopic cylinder 27 is telescopically arranged toward the workbench 1 , and a rotating plate 28 is fixedly connected to the end of the piston rod of the telescopic cylinder 27 .

[0065] A pressing mechanism 5 and a pre-installing mechanism 4 are provided on the same side of the rotating plate 28 , and the structure of the pressing mechanism 5 is consistent with that of the pressing mechanism 5 in the above-mentioned embodiment 1, and the structure of the pre-installing mechanism 4 is consistent with that of the pre-installing mechanism 4 in the above-mentioned embodiment 1.

[0066] The preloading plate 401 on the preloading mechanism 4 extends below the material storage block 303 , and the positions of the preloading hole 16 and the material limiting hole 8 correspond to each other.

[0067] The working process of Example 2 in the present application is as follows: the spring in the storage block 303 directly falls into the pre-installation hole 16 through the storage hole, and the pre-installation plate 401 is extended from the bottom of the storage block 303 by driving the electric slide 25. Secondly, the pre-installation plate 401 is moved to the top of the pre-installed product by driving the cooperation of the rotating structure 26 and the telescopic cylinder 27, and the electric slide 25 is used for fine adjustment so that the spring installation groove on the pre-installed product accurately corresponds to the position of the pre-installation hole 16, and finally the spring is accurately and firmly installed in the pre-installed product by pressing the ejector pin 502.
