Technical Field

[0001] The utility model belongs to the technical field of positioning structures, in particular to a positioning structure for a hydraulic press. Background Art

[0002] A hydraulic press is a machine that uses the static pressure of liquid to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and forming processes. After a long period of use, the hydraulic press will cause positional offset between the extrusion plates, which will lead to inaccurate positioning and extrusion offset during use of the hydraulic press. In serious cases, the extruded object will be damaged. For this reason, a positioning device is needed to position the up and down extrusion movement of the hydraulic press to ensure that the hydraulic work does not deviate.

[0003] In the prior art, the positioning columns of the hydraulic press positioning and alignment device are mostly fixed points. Therefore, when the length of the object requiring hydraulic pressure is greater than the distance between the positioning columns, the distance between the positioning columns cannot be adjusted, so that the hydraulic work cannot be performed normally, and the flexibility and adaptability of the hydraulic work is not high.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Example 1

[0026] Please refer to Figure 1-3 As shown, this embodiment provides a positioning structure for a hydraulic press, including a top plate 1 and a bottom plate 2, wherein the top plate 1 is arranged parallel to the top of the bottom plate 2, and the rest of the structure of the hydraulic press is the prior art. The side ends of the top plate 1 and the bottom plate 2 are provided with fixing holes 4 for connecting the base and the top seat of the hydraulic press respectively.

[0027] In order to solve the problem that the spacing between the positioning columns in the prior art is not adjustable, an adjustable positioning mechanism 3 is designed to solve this problem. The adjustable positioning mechanism 3 is vertically adjustable and arranged between the top plate 1 and the bottom plate 2, so as to adjust the spacing between the top plate 1 and the bottom plate 2. The top plate 1 and the bottom plate 2 can be arranged at the side ends of the upper and lower extrusion plates of the hydraulic press as needed.

[0028] refer to Figure 3 As shown, the adjustable positioning mechanism 3 comprises a limit column 31, a threaded adjustment sleeve 32 and an adjustment rod 33, wherein the limit column 31 is installed on both sides of the bottom of the top plate 1, the limit column 31 is hollow inside and has a convex-shaped slot hole inside, the threaded adjustment sleeve 32 is installed on the inner bottom of the slot hole of the limit column 31, and the bottom of the adjustment rod 33 is installed on the bottom plate 2, and the adjustment rod 33 moves up and down between the hollow part of the threaded adjustment sleeve 32 and the slot hole of the limit column 31.

[0029] Among them, the adjusting rod 33 includes a telescopic section 331 and a threaded section 332 connected up and down. The threaded section 332 is located in the lower limit seat 21, and the telescopic section 331 is located in the upper limit seat 11. The outer wall of the threaded section 332 is threadedly connected to the inner wall of the threaded adjustment sleeve 32. An adjusting seat 34 is provided at the outer bottom of the threaded adjustment sleeve 32. The adjusting seat 34 is located at the outer bottom of the limit column 31. The rotation of the adjusting seat 34 drives the rotation of the threaded adjustment sleeve 32, thereby generating a meshing relationship with the threaded section 332 to adjust the spacing of the stroke height.

[0030] In addition, the bottom of the top plate 1 extends downward to form an upper limit seat 11, and the top of the bottom plate 2 extends upward to form a lower limit seat 21. The top plate 1 and the upper limit seat 11 are arranged in an inverted concave shape, and the bottom plate 2 and the lower limit seat 21 are arranged in a concave shape. The arrangement of the upper limit seat 11 and the lower limit seat 21 plays a supporting role during the lifting work, further enhancing the stability of the positioning structure.

[0031] Furthermore, mounting holes 12 are opened on both sides of the top plate 1, the top of the limiting column 31 is installed in the mounting hole 12, and a bearing 13 is provided between the limiting column 31 and the mounting hole 12, so that the limiting column 31 can also realize rotational movement.

[0032] Before using the utility model, the positioning structure is first fixedly installed between the top plate 1 and the bottom plate 2 and the hydraulic press, and the adjustable positioning mechanism 3 is used to achieve the effect of hydraulic positioning.

[0033] When using the utility model, by setting the adjustable positioning mechanism 3, the travel range between the top plate 1 and the bottom plate 2 is adjusted according to the needs by combining the upper and lower telescopic sections 331 and the threaded section 332. The rotation of the adjusting seat 34 drives the rotation of the threaded adjusting sleeve 32, thereby generating a meshing relationship with the threaded section 332, and then adjusting the spacing of the travel height. During the hydraulic operation, the telescopic section 331 of the adjusting rod 33 moves up and down about the hollow interior of the limit seat, providing a corresponding hydraulic stroke, providing a good support effect, and preventing deformation. It is used to solve the problem of the non-adjustable spacing of the positioning columns in the prior art, and ensure the flexibility and normal operation of the hydraulic operation.

[0034] The illustration only provides an embodiment, and the specific travel distance and product size can be designed according to needs.

[0035] It should be noted that although the embodiments of the utility model have been shown and described, for ordinary technicians in this field, without departing from the inventive purpose of the utility model, structural methods and embodiments similar to the technical scheme without creative design should all fall within the scope of protection of the utility model.
