DETAILED DESCRIPTION

[0021] 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.

[0022] Example: Figure 1 - Figure 4 As shown, a hydraulic cylinder positioning and clamping device includes a base 1, the top of the base 1 is movably connected to a rotating frame 2 through a bearing, the rotating frame 2 is driven by an external motor, and multiple groups of pallets 3 are fixed to the end of the rotating frame 2 by spot welding, the top and bottom of the pallet 3 are respectively fixedly connected to an upper bracket 401 and a lower bracket 402, the upper bracket 401 and the lower bracket 402 are symmetrically arranged, and the top of the upper bracket 401 is obliquely fixedly connected to an upper slide 501, a push rod 502 is slidably connected inside the upper slide 501, one end of the push rod 502 is fixedly connected to a cover plate 6, and a slot matching the hydraulic cylinder is provided on the inner side of the cover plate 6.

[0023] The outer side of the tray 3 is provided with a tightening assembly 7, which includes a rotating rod 701 and a guide rail 702. The rotating rod 701 is rotatably connected to the side wall of the tray 3, and the guide rail 702 is fixedly connected to both ends of the rotating rod 701. A guide groove is provided on the outer side of the guide rail 702. The end of the push rod 502 away from the arc cover plate 6 is fixedly connected to a connecting frame 8. The bottom end of the lower bracket 402 is fixedly connected to a sliding cylinder 703, and a sliding rod 704 is slidably connected in the sliding cylinder 703. One end of the sliding rod 704 is fixedly connected to a connecting frame 2 705. The outer walls of the frame 1 8 and the connecting frame 2 705 are fixed with a protrusion 9 by spot welding. The protrusion 9 is slidably connected in the driving groove opened by the guide rail 702. The end of the sliding rod 704 away from the connecting frame 2 705 is fixedly connected with the limiting rod 706. A placement groove 10 is opened on the top of the tray 3. A ring plate 11 is fixedly installed on the top of the base 1. Two arc grooves 12 and two limiting grooves 13 are opened on the top of the ring plate 11. The limiting grooves 13 are connected with the corresponding arc grooves 12. The limiting rod 706 is slidably connected in the arc grooves 12 and the limiting grooves 13.

[0024] When setting specifically, the assembled hydraulic cylinder barrels are sequentially placed in the corresponding placement grooves 10, the motor controls the rotating frame 2 to rotate, and at the same time, the limit rod 706 slides in the limit groove 13. When the limit rod 706 slides from the limit groove 13 to the arc groove 12, the distance between the two limit rods 706 increases, thereby driving the slide bar 704 to slide directionally in the lower slide cylinder 703. During the sliding process, the slide bar 704 cooperates with the protrusion 9 and the second connecting frame 705, thereby driving the rotating rod 701 to deflect. During the deflection process, the rotating rod 701 cooperates with the connecting frame 1 8 and the protrusion 9, thereby driving the push rod 502 to slide in the upper slide cylinder 501.

[0025] When the push rod 502 slides downward, the cover plate 6 is driven to move. The inner wall of the cover plate 6 is provided with a slot, which is used to limit and fix the outer side of the hydraulic cylinder. Figure 1 As shown, the upper slide 501 is arranged at an angle, and the cover plate 6 can abut and fix the hydraulic cylinder horizontally and vertically downward under the action of the inclined push rod 502, thereby further improving the positioning effect of the hydraulic cylinder;

[0026] The assembly and processing of the hydraulic cylinder are completed during the sliding of the push rod 502 in the arc groove 12. After completion, the push rod 502 slides from the arc groove 12 to the limit groove 13. At this time, the distance between the two corresponding limit rods 706 becomes smaller, thereby allowing the cover plate 6 to release the clamping fixation on the outside of the hydraulic cylinder, making it easier to take out the processed hydraulic cylinder.

[0027] By providing interconnected arc grooves 12 and limit grooves 13, the distance between the corresponding two limit rods 706 is changed, thereby realizing adaptive clamping and releasing of the hydraulic cylinder by the cover plate 6, and cooperating with the rotating frame 2 to realize automated tightening and continuous processing of the hydraulic cylinder with high efficiency.
