It is a multi-functional medium and small-sized hydraulic press, suitable for the correction of shaft parts, profiles and the press-fitting of bushing parts.

[0003] In the existing technology, when the hydraulic press is in use, the workpiece is simply placed on the workbench. During the specific use process, it is inconvenient to determine whether the workpiece is directly below the axis of the piston rod. Therefore, when the piston rod is driven to press-fit the workpiece placed on the workbench, the placed position deviates from the direct lower end of the piston rod, resulting in the piston rod not hitting or being deflected, affecting the processing efficiency and quality.

[0004] The existing patent (publication number: CN220163318U) discloses a high-speed single-column hydraulic press with a correction function. The workpiece is placed on the bearing table. By rotating the torsion bar at the outer end of the third screw respectively, the third screw is driven to rotate. The third screw drives the driving block and the clamping block to move towards the workpiece along the direction of the chute until all the clamping blocks clamp the workpiece to restrain the workpiece.

[0005] In view of the above problems, although the solution given by the existing patent can clamp and correct the position of the workpiece through the cooperation of components such as the third screw, during the specific use process, it is necessary to manually adjust the four groups of third screws in turn, resulting in difficulty in ensuring that the four groups are at the same frequency, making it inconvenient to keep the workpiece in the middle position during the adjustment process, and there may be certain errors, affecting the processing accuracy.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figure 1 and Figure 2 , a high-speed single-column hydraulic press with a correction function, comprising a hydraulic press body 1. A first sliding plate 2 is fixed at the axial end of the hydraulic press body 1. A second sliding plate 3 is slidably connected above the first sliding plate 2. A bearing platform 4 is slidably connected to the top end of the second sliding plate 3. A positioning mechanism 5 is arranged inside the bearing platform 4; the positioning mechanism 5 includes a chute 501. Four chutes 501 are opened at the top end of the bearing platform 4. A clamping plate 502 is slidably connected above the bearing platform 4. One end of the clamping plate 502 passing through the chute 501 is fixed with a slider 503. A threaded rod 504 is connected inside the slider 503. One end of the threaded rod 504 is fixed with a first bevel gear 505. A second bevel gear 506 is connected below the first bevel gear 505. A driving rod 507 is fixed at the bottom end of the second bevel gear 506. A driving motor 508 is connected below the driving rod 507. The clamping plate 502 forms a sliding structure with the chute 501 through the slider 503. The clamping plate 502 forms a sliding structure with the bearing platform 4. The threaded rod 504 is threadedly connected with the slider 503. The slider 503 forms a sliding structure with the threaded rod 504.

[0028] By adopting the above technical solutions, the first sliding plate 2 and the second sliding plate 3 are adjusted by corresponding motors and screws to drive the bearing platform 4 to drive the position of the workpiece, and the piston rod is corrected on the hydraulic press body 1. At the same time, driven by the driving motor 508, the driving rod 507 drives the second bevel gear 506, thereby pushing the first bevel gear 505, enabling the four threaded rods 504 to rotate simultaneously, and the slider 503 drives the clamping plate 502 to slide stably along the chute 501 on the bearing platform 4, and clamping and limiting the workpiece and correcting the position from four directions simultaneously, avoiding errors caused by manual rotation or adjustment and affecting the accuracy of the corrected position.

[0029] Specifically, as Figures 2 to 4As shown in the figure, a limiting mechanism 6 is provided on one side of the clamping plate 502. The limiting mechanism 6 includes a placement groove 601 which is opened at the front end of the clamping plate 502. A support rod 602 is fixed inside the placement groove 601. A fitting plate 603 is rotatably connected to the outer wall of the support rod 602. The limiting mechanism 6 further includes a fixed block 604 which is fixed on one side of the outer wall of the clamping plate 502. A permanent magnet rod 605 penetrates through the outer wall of the fixed block 604 facing the fitting plate 603. One end of the permanent magnet rod 605 penetrating through the fixed block 604 is movably connected to a universal ball seat 606. A limiting ring 607 is fixed on the outer wall of one end of the permanent magnet rod 605 located in the fixed block 604. An iron core 608 is arranged on one side of the limiting ring 607. A coil 609 is arranged outside the iron core 608. The support rod 602 penetrates into the fitting plate 603. A rotating structure is formed between the fitting plate 603 and the support rod 602. The universal ball seat 606 is fixedly connected to the fitting plate 603. A telescopic structure is formed between the universal ball seat 606 and the fixed block 604 through the permanent magnet rod 605.

[0030] By adopting the above technical solution, when the clamping plate 502 clamps, the coil 609 is started to make the iron core 608 generate magnetic force, so as to push the permanent magnet rod 605 to penetrate out of the fixed block 604, and the fitting plate 603 is pushed through the universal ball seat 606 to clamp towards the workpiece position. The fitting plate 603 rotates along the placement groove 601 through the support rod 602, and the angle is automatically adjusted in cooperation with the universal ball seat 606, so as to be able to fit and clamp special-shaped or circular workpieces, improving the applicability during the correction position, and at the same time, the permanent magnet rod 605 is prevented from sliding excessively and detaching from the fixed block 604 through the limiting ring 607.

[0031] Working principle: Both the first sliding plate 2 and the second sliding plate 3 are provided with motors and matching screws to correct the position, so as to facilitate the accurate stamping of the hydraulic press body 1. When the workpiece is on the bearing table 4, the driving rod 507 is driven by the driving motor 508, and the second bevel gear 506 is driven to push the four first bevel gears 505 to rotate, so that the corresponding threaded rods 504 rotate, and the slider 503 drives the clamping plate 502 to slide along the chute 501, clamping and correcting the workpiece from four sides to avoid deviation. At the same time, the coil 609 is started to make the iron core 608 generate magnetic force, so as to push the permanent magnet rods 605 of the same magnetic pole to penetrate out of the fixed block 604. The limiting ring 607 prevents excessive penetration and detachment. The universal ball seat 606 connected to the permanent magnet rod 605 is fixedly connected to the fitting plate 603. After rotating with the clamping plate 502 through the support rod 602 and the placement groove 601 under the push, the angle is automatically adjusted and the workpiece is fitted and clamped, so as to be suitable for clamping circular or special-shaped workpieces and improve the applicability.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
