[0002] A piston is a mechanical part that reciprocates along the cylinder axis in the cylinder of machines such as reciprocating piston internal combustion engines, compressors, and pumps. There are three forms of pistons: disc-shaped, cylindrical, and cylindrical tube-shaped. During the assembly process, the piston needs to be assembled on the piston shaft first and then fixed in the piston flywheel. During the assembly process of the piston shaft, piston flywheel, and piston, it is necessary to keep each component in the correct position, which requires high precision.

[0012] Further, for the profiling platform, the arc-shaped concave surfaces face each other and are fixed on both sides of the through hole of the third positioning plate.

[0013] Further, anti-fooling protrusions are respectively arranged on the profiling table, and the two protrusions are opposite to each other at an oblique angle.

[0014] Further, both sides of the workbench are placed on the connecting frame, and the supporting rods fixed at the bottom and the driving ends pass through and are limited within the fixing plate connected to the bottom of the connecting frame.

[0037] The following further describes the present solution in conjunction with the accompanying drawings and embodiments:

[0038] Embodiment 1:

[0039] A piston assembly placement tooling, as shown in the figure, includes a limiting portion 110 on a workbench 100.

[0040] The workbench 100 is placed on both sides on the connecting frame 200, and the support rods 101 fixed at the bottom and the driving end 120 pass through and are limited within the fixed plate 210 connected to the bottom of the connecting frame 200. The support rods 101 are arranged at the four corners of the bottom connecting plate 102 of the workbench 100, and the driving end 120 is arranged at the center of the bottom of the workbench 100.

[0041] Before the piston assembly is assembled, two processes of loading and unloading are required, and the moving stroke of the loading and unloading mechanism is limited. The driving end 120 provided in the present solution acts on the bottom of the workbench 100 to control the lifting of the workbench 100, and can simultaneously meet the moving stroke of loading and unloading. In this embodiment, the driving end 120 is a cylinder, which can be directly purchased from SMC (China) Co., Ltd., and the model is CDQ2B32-20DCZ-M9BL. The specific working principle is a commonly used technology in the art and will not be elaborated here.

[0042] Specifically, the workbench 100 is connected to the production line through the connecting frame 200, and by controlling the driving end 120 to lift the connecting frame 200, the height of the workbench 100 can meet the requirements of the production line.

[0043] As shown in the figure, the side of the workbench 100 further includes a sensor 300, and the sensor 300 is used to receive signals and control the cylinder at the bottom of the workbench 100 to work.

[0044] As shown in the figure, the workbench surface of the workbench 100 includes a limiting portion 110 for placing the piston assembly.

[0045] The limiting portion 110 includes a first support position 111 for placing the piston shaft 1, a second support position 112, and a third support position 113 for placing the piston flywheel 2.

[0046] The piston shaft 1 has shaft bodies at both the upper and lower ends. It is first placed on the first support position 111 through the feeding station, and then flipped to the second support position 112 through the flipping station.

[0047] The first support position 111 includes a first shaft seat 1112 on the first positioning plate 1111 and a support frame 1113.

[0048] The bottom column of the first shaft seat 1112 is hollow, and the opening at the bottom of the first shaft seat 1112 is aligned with the through holes of the first positioning plate 1111 and the workbench 100. The upper support platform is combined with the outer periphery of the column. After the long shaft of the piston shaft 1 is placed, the top of the long shaft of the piston shaft 1 fits against the first shaft seat 1112.

[0049] Specifically, after the piston shaft 1 is loaded, the top of the long shaft of the piston shaft 1 fits against the support platform, the shaft body is limited within the column, and the support frame 1113 supports the edge of the piston shaft 1.

[0050] The second support position 112 includes a second shaft seat 1122 on the second positioning plate 1121. The second shaft seat 1122 is hollow and the bottom opening is aligned with the through holes of the second positioning plate 1121 and the workbench 100.

[0051] Specifically, after receiving the instruction, the flipping station in the production line grabs the piston shaft 1 from the first support position 111, flips it, and then places it on the second support position 112. The short shaft of the piston shaft 1 is limited within the second shaft seat 1122, and the top of the second shaft seat 1122 limits the top of the short shaft of the piston shaft 1.

[0052] The third support position 113 is used to limit the piston flywheel 2 and includes two profiling platforms 1132 on the third positioning plate 1131. The profiling platforms 1132 have their arc-shaped concave surfaces facing each other and are fixed on both sides of the through hole of the third positioning plate 1131.

[0053] An anti-fooling convex part 1133 is respectively arranged on each of the profiling platforms 1132, and the two convex parts have their oblique angles facing each other.

[0054] The profiling platform 1132 provided in this solution can ensure the placement angle of the piston flywheel 2 and avoid failures in subsequent steps.

[0055] Further explanation in combination with its usage mechanism:

[0056] After the piston shaft 1 is loaded, the top of the long shaft of the piston shaft 1 fits against the support platform, the shaft body is limited within the column, and the support frame 1113 supports the edge of the piston shaft 1. The station for transporting the piston flywheel 2 moves synchronously and places the piston flywheel 2 on the third support position 113.

[0057] After receiving an instruction, the flipping station on the production line grabs the piston shaft 1 from the first support position 111, flips it, and then places it on the second support position 112. The short shaft of the piston shaft 1 is limited within the second shaft seat 1122, and the top of the second shaft seat 1122 limits the top of the short shaft of the piston shaft 1.

[0058] In summary, the workbench provided in this application integrates multiple limiting parts and simultaneously fixes the piston shaft and the piston flywheel.

[0059] The limiting parts provided in this application have a profiling structure that well limits the piston shaft and the piston flywheel, eliminating the need for manual placement operations, ensuring the placement angle of the piston assembly, and realizing the automation of the production line.
