Detailed implementation manners

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: a spring assembly pressing device, including a pressing device main body 1, an upper mounting plate 4 is provided on the pressing device main body 1, a pressing plate 7 is installed at the bottom of the upper mounting plate 4, and a lower positioning seat 3 is provided below the upper mounting plate 4. A bottom plate 2 that is screwed and fixed to the lower positioning seat 3 is provided at the bottom of the pressing device main body 1, and a mounting plate 5 and a pressing drive hydraulic cylinder 6 are also screwed and fixed on one side of the upper end of the bottom plate 2. The mounting plate 5 is an inverted L-shaped structure. This structure is supported at the bottom by the bottom plate 2, so that the pressing device main body 1 can be placed on the platform. The pressing drive hydraulic cylinder 6 is stably installed through the bottom plate 2 and the mounting plate 5. A positioning groove 302 corresponding to the position of the pressing plate 7 is opened on the lower positioning seat 3, and communication-limiting grooves 303 are symmetrically opened on both sides of the positioning groove 302. A spring seat clamping member 13 is movably engaged in the limiting grooves 303. Side mounting plates 401 are symmetrically provided on both sides of the upper mounting plate 4. The upper end of the pressing drive hydraulic cylinder 6 is screwed and fixed to the mounting plate 5. A piston rod 601 is installed in the pressing drive hydraulic cylinder 6. The piston rod 601 is in through-fit with the mounting plate 5, and the upper end of the piston rod 601 is screwed and fixed to the upper mounting plate 4. This structure can drive the piston rod 601 to lift and lower by the pressing drive hydraulic cylinder 6, realizing the up and down movement of the upper mounting plate 4, and thus realizing the pressing process of the spring assembly. Positioning protrusions 301 of an integral structure are symmetrically provided on both sides of the upper end of the lower positioning seat 3, and a second clamping drive hydraulic cylinder 14 is installed between the positioning protrusions 301 and the spring seat clamping member 13. This structure enables the second clamping drive hydraulic cylinder 14 to be horizontally installed, so that the second clamping drive hydraulic cylinder 14 can drive the spring seat clamping member 13 to move under the positioning of the positioning protrusions 301, enabling the spring seat placed in the positioning groove 302 to be firmly clamped by the spring seat clamping member 13, ensuring the accuracy of the relative position between the spring seat and the spring, and ensuring the quality of the spring assembly pressing. L-shaped connecting plates 8 are respectively connected to the lower ends of the side mounting plates 401. A limiting rod 9 is provided between the connecting plate 8 and the side mounting plate 401. The limiting rod 9 is movably penetrated by a mounting seat 10. The limiting rod 9 is a square tube structure to prevent the mounting seat 10 from rotating. Spring positioning members 12 are respectively provided on the opposite sides of the mounting seat 10, and first clamping drive hydraulic cylinders 11 are respectively connected between the mounting seat 10 and the spring positioning members 12. The mounting seat 10 is a T-shaped structure, and the first clamping drive hydraulic cylinders 11 are respectively screwed and fixed at both ends of the mounting seat 10. This structure enables the spring positioning members 12 to be stably installed through the first clamping drive hydraulic cylinders 11. When the spring positioning members 12 clamp the spring, the spring positioning members 12 can be inserted into the spring gap to realize the positioning of the spring. The spring positioning members 12 are inclined, and the two side spring positioning members 12 are inclined in opposite directions. This structure enables the spring positioning members 12 to be smoothly inserted into the spring gap through the inclined setting. The mounting seat 10 is movably connected to the limiting rod 9, so that when the pressing plate 7 moves down for pressing, the mounting seat 10 can only move up and down for the positioning of the spring, avoiding the deviation of the spring position.

[0020] Working principle: When using this spring assembly press-fitting device, first place the spring seat in the positioning groove 302 of the lower positioning seat 3. The second clamping drive hydraulic cylinder 14 drives the spring seat clamping member 13 to move under the positioning of the positioning projection 301, and positions the spring seat through the spring seat clamping member 13. The limiting groove 303 is used for the movement limit of the spring seat clamping member 13. Place the spring on the spring seat, and then make the first clamping drive hydraulic cylinder 11 drive the spring positioning member 12 to move under the positioning of the mounting seat 10. By making the spring positioning members 12 on both sides snap into the spring gap, the positioning of the spring is achieved. Then start the press-fitting drive hydraulic cylinder 6, and make the press-fitting drive hydraulic cylinder 6 drive the piston rod 601 to drive the upper mounting plate 4 to move downward under the stable positioning of the bottom plate 2 and the mounting plate 5, so that the press-fitting plate 7 performs press-fitting and fixing processing on the spring assembly. The side mounting plate 401 moves downward synchronously. Since the mounting seat 10 moves relative to the connecting plate 8 and the side mounting plate 401 through the limiting rod 9, the downward movement of the side mounting plate 401 does not affect the clamping work of the spring positioning member 12, ensuring the reliable press-fitting of the press-fitting device main body 1 to the spring assembly, and thus completing a series of operations.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
