[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] Example 1:

[0034] A piston assembly feeding structure, such as Figure 1-6 As shown, it includes a robotic arm 3 and a clamping part 100.

[0035] In the prior art, during the assembly process of the piston flywheel 1, the piston shaft 2 and the piston, the piston flywheel 1 and the piston shaft 2 need to be loaded manually.

[0036] This solution combines the robotic arm 3 and the clamping part, and performs the loading work of the piston assembly through automation, thereby reducing labor costs and improving production efficiency.

[0037] The fixing rod 220 of the mechanical arm 3 passes through the through hole and is connected to the clamping portion 100 below. In this solution, the position of the clamping portion 100 is changed by controlling the rotation of the mechanical arm 3.

[0038] The robot arm 3 of this solution can be purchased from DENSO Corporation of Japan, and the model is HM-40703 / RC8A-HMAONNEMNN-NNN. The robot arm 3 is a prior art and will not be elaborated on here.

[0039] refer to Figure 1-6 The clamping portion 100 includes a first limiting structure 110 and a second limiting structure 120 .

[0040] The clamping portion 100 provided in this solution simultaneously clamps the piston shaft 2 and the piston flywheel 1 in an integrated manner, thereby maximizing the use of production space and reducing production costs.

[0041] like Figure 1-5 As shown, the first limiting structure 110 acts on the piston flywheel 1, and a connecting plate 112 is fixed under the first bracket 111. The connecting plate 112 includes a slide rail 1121. The first clamping assembly 113 is limited on the slide rail 1121 of the connecting plate 112 and slides along the direction of the slide rail 1121.

[0042] The first clamping assembly 113 includes a T-shaped bracket 1131 with a clamping claw 1132 at the top, sliders 1133 at right angles on both sides of the bottom connected to the slide rail 1121 , and the bottom protruding end is sleeved on the driving end 1134 .

[0043] The driving end 1134 acts on the first clamping assembly. In this embodiment, the driving end is a cylinder, which can be purchased directly from SMC (China) Co., Ltd., model CDQ2B32-20DCZ-M9BL. The specific working principle is a common technology in this field and will not be described in detail.

[0044] In this solution, two first clamping assemblies 113 are provided, and two clamping jaws 1132 are arranged opposite to each other. In order to clamp the piston flywheel 1, the opening size of the clamping jaws 1132 is adapted to the piston flywheel 1, and the opening on one side is larger than the opening on the other side.

[0045] Specifically, under the action of the robotic arm 3, when the clamping jaws 1132 on the first bracket 111 moves to the feed port, the driving end 1134 drives the T-shaped bracket forward to link the two clamping jaws 1132 to move on the slide rail 1121, and the distance between the two clamping jaws 1132 is reduced, and the piston flywheel 1 is limited in the middle of the clamping jaws 1132. The robotic arm 3 rotates to transfer the piston flywheel 1 to the next workstation, and the driving end 1134 is reset, driving the two clamping jaws 1132 to move to both sides, and the piston flywheel 1 falls into the next workstation.

[0046] like Figure 1-3 As shown, the top surface of the first bracket 111 fixes the connecting portion 200 and the second limiting structure 120 .

[0047] The connecting portion 200 includes a hollow connecting seat 210 and an internal limiting fixing rod 220 .

[0048] like Figure 1-4 and Figure 6 As shown, the second limiting structure 120 includes a second clamping assembly 122 at the bottom of a second bracket 121 acting on the piston shaft 2.

[0049] The second clamping assembly 122 is a mechanical clamp in this embodiment, which can be directly processed from a corresponding supplier and is a non-standard part. The specific working principle is a common technology in this field and will not be described in detail.

[0050] Specifically, under the action of the robotic arm 3, the second clamping assembly 122 on the second bracket 121 clamps the piston shaft 2 from the feed end and transfers it to the next station. After being transferred to the next station, the second clamping assembly 122 is released.

[0051] Further explanation based on its usage mechanism:

[0052] Under the action of the robotic arm 3, when the clamp on the first bracket 111 moves to the feed port, the driving end 1134 drives the T-shaped bracket forward to move the two clamps on the slide rail 1121, and the distance between the two clamps is reduced, so that the piston flywheel 1 is restricted in the middle of the clamp. The mechanical clamp on the second bracket 121 is clamped, and the piston shaft 2 is restricted in the middle of the mechanical clamp. The robotic arm 3 rotates to transfer the piston flywheel 1 and the mechanical clamp to the next station.

[0053] After reaching the next station, the driving end 1134 is reset, driving the two clamps to move to both sides, the piston flywheel 1 falls into the next station, the mechanical clamp is released, and the piston shaft 2 falls into the next station.

[0054] In summary, the combination of the robotic arm 3 and the clamping portion 100 provided in the present application automates the loading of the piston assembly, thereby reducing labor costs and improving production efficiency.

[0055] The clamping portion 100 provided in the present application simultaneously clamps the piston shaft 2 and the piston flywheel 1 in an integrated manner, thereby maximizing the use of production space and reducing production costs.
