[0019] The following will be combined with the drawings in the embodiments of the utility model 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 in 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.

[0020] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0021] A six-sided top press piston assembly device, comprising a workbench 1, a U-shaped limit frame 11 and a fixed plate 12 are fixedly installed on the upper surface of the workbench 1, a hydraulic push rod 2 is fixedly installed on the right surface of the fixed plate 12, a U-shaped movable frame 3 is fixedly installed on the right surface of the hydraulic push rod 2, two carriers 31 are symmetrically fixedly installed on the left end of the U-shaped movable frame 3, the carriers 31 are slidably arranged in the U-shaped limit frame 11, a plurality of piston positioning grooves 311 are equidistantly provided on the upper surface of the front carrier 31, a plurality of piston cylinder positioning grooves 312 are equidistantly provided on the upper surface of the rear carrier 31, the distance between two adjacent piston positioning grooves 311 is the same as the distance between two adjacent piston cylinder positioning grooves 312, and a pressure-taking integrated device 4 is fixedly installed on the upper surface of the workbench 1;

[0022] When the piston and the piston cylinder are placed in the corresponding piston positioning groove 311 and the piston cylinder positioning groove 312, the hydraulic push rod 2 can be used to push the U-shaped movable frame 3 to move right, so that the carrier 31 can be moved to the outside of the assembly area for loading. After loading, the hydraulic push rod 2 is used to move the carrier 31 to the left to the end of the inner cavity of the U-shaped limit frame 11 for positioning. The two positioned carriers 31 are respectively located directly below the material taking and assembly positions of the integrated pressure taking device 4. At this time, the integrated pressure taking device 4 is used to take out the piston and move it to the top of the piston cylinder for downward pressing and assembly. Compared with the prior art, the entire assembly process can realize batch assembly tooling of pistons, with higher work efficiency and easier mass production and use.

[0023] It should be noted that if Figure 4 As shown, the integrated pressure-taking device 4 comprises an electric rotating worktable body 41, which is fixedly mounted on the upper surface of the worktable 1, and a hydraulic lifting column 42 and a directional rod 43 are fixedly mounted at the center of the upper surface of the electric rotating worktable body 41, and an L-shaped hanging frame 44 is fixedly mounted on the upper surface of the hydraulic lifting column 42, and the L-shaped hanging frame 44 is slidably mounted on the outer surface of the directional rod 43, and a pressing frame 45 is fixedly mounted on the lower surface of the L-shaped hanging frame 44, and a plurality of convex mounting grooves 451 are equidistantly provided on the lower surface of the pressing frame 45, and the convex mounting grooves 451 are located directly above the corresponding piston positioning grooves 311, and electromagnetic suction rings 46 are fixedly mounted in the convex mounting grooves 451, and a rubber pressing block 47 is fixedly mounted on the top of the inner cavity of the convex mounting grooves 451;

[0024] When the integrated taking and pressing device 4 is taking materials, the pressing frame 45 is first rotated to the top of the front end loading platform 31 by the electric rotating workbench main body 41 through the hydraulic lifting column 42, the directional rod 43 and the L-shaped hanging frame 44, and then the hydraulic lifting column 42 is contracted to cover the convex mounting groove 451 and the electromagnetic suction ring 46 on the outer surface of the piston, and the electromagnetic suction ring 46 is turned on to generate magnetic force to absorb the piston, and then the hydraulic lifting column 42 is extended to vertically take the piston out of the piston positioning groove 311, and then, with the help of the electric rotating workbench main body 41, the pressing frame 45 is rotated 180 degrees so that the piston is located directly above the piston cylinder, and then, the hydraulic lifting column 42 is contracted to drive the pressing frame 45 and the piston to move downward, and the piston is assembled into the piston cylinder. When the piston enters the piston cylinder, the magnetic force of the electromagnetic suction ring 46 is released, so that the hydraulic lifting column 42 continues to contract. At this time, the pressing frame 45 continues to move downward, and the rubber pressure block 47 is used to press the piston downward, thereby completing the final assembly work.

[0025] In addition, in order to ensure that the carrier 31 can move horizontally left and right under the drive of the hydraulic push rod 2, Figure 3As shown, the upper surface and the right surface of the U-shaped limit frame 11 are symmetrically bent inward to form an integral limit rib 11, and the lower surface of the upper limit rib 111 is in contact with the upper surface of the carrier 31. The upper limit rib 111 can be used to limit the upper surface of the carrier 31 so that it can move horizontally to ensure stability during movement and avoid displacement of materials placed in the piston positioning groove 311 and the piston cylinder positioning groove 312 during movement, which would affect the positioning effect.

[0026] In addition, in order to further increase the load-bearing strength of the carrier 31, Figure 2 As shown, load-bearing rollers 32 are fixedly installed on the lower surface of the carrier 31, and the load-bearing rollers 32 are rollingly set on the upper surface of the workbench 1. The load-bearing rollers 32 can share the load-bearing of the carrier 31, thereby increasing the load-bearing strength of the carrier 31.

[0027] Finally, in order to ensure that the pressing frame 45 can accurately pick up materials and accurately press down for assembly, the electric rotating worktable body 41 needs to be located on the inner side of the U-shaped limit frame 11, and the distance between the electric rotating worktable body 41 and the two carriers 31 should be the same. This ensures that the pressing frame 45 can be freely moved between the material picking area and the pressing and assembly area after rotating 180 degrees.
