Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and in particular to a hydraulic press frame that is easy to assemble. Background Technology

[0002] Hydraulic presses are based on Pascal's law and achieve energy conversion by transmitting pressure through a closed liquid. They have high-pressure output and multi-stage pressure control capabilities, and can complete complex molding and processing tasks.

[0003] Chinese Patent Publication No. CN207088561U discloses a novel hydraulic press mobile frame, including a hydraulic cylinder, crossbar, side columns, processing platform, main frame, mobile device, support device, control cabinet, and pressure plate, as well as hydraulic pipe interfaces. The mobile device is welded to the four lower corners of the main frame; the support device is welded to the four lower corners of the main frame. The shock absorber design of this invention facilitates stable movement of the hydraulic press, making it suitable for various uneven road surfaces. The mobile wheels facilitate convenient movement of the hydraulic press. The processing platform ensures secure placement of workpieces, resulting in high processing efficiency. The support device simplifies placement and ensures secure fixation of the hydraulic press. The ribs reinforce the mobile device, extending its service life and increasing its load-bearing capacity, making it more convenient to use and facilitating widespread adoption.

[0004] This device adopts an integrated welded frame structure, which is lightweight, compact, and easy to move. However, its parallelism adjustment of the processing platform and the pressure plate has a significant drawback. Specifically, the device relies solely on unscrewing the support rod to adjust the parallelism of the processing platform and the pressure plate, making it difficult to quickly align them. To address this deficiency, we propose a hydraulic press frame that is easy to assemble. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a hydraulic press frame that is easy to assemble, comprising: a base, a main body, and a positioning structure.

[0031] The base includes a base plate 10, a base 11 fixedly installed on the upper surface of the base plate 10, and an assembly plate 12 fixedly installed on the upper surface of the base 11. The surface of the base plate 10 is provided with a first adjustment assembly. The first adjustment assembly includes a bottom corner 30, a first threaded post 31 fixedly installed on the upper surface of the bottom corner 30, and a first adjusting nut 32 and a second adjusting nut 33 respectively threadedly connected to the surface of the first threaded post 31. The surface of the base plate 10 is provided with a through hole for the first threaded post 31 to pass through. The first adjusting nut 32 is located on the upper surface of the base plate 10, and the second adjusting nut 33 is located on the lower surface of the base plate 10. When the base plate 10 is placed flat on the ground, four sets of the first adjustment assembly are installed through the through hole. The first threaded post 31 of the bottom corner 30 passes through the base plate 10. By adjusting the height of the first adjusting nut 32 and the second adjusting nut 33, the level of the base plate 10 can be roughly adjusted to ensure the stability of the base installation.

[0032] The main body includes a top plate 20, four columns 21 fixedly installed at equal intervals on the lower surface of the top plate 20, a pressure plate 22 slidably installed on the surface of the columns 21, and a worktable 23 set below the pressure plate 22. The upper surface of the top plate 20 is provided with cylinder mounting holes.

[0033] A second adjustment assembly is provided between the workbench 23 and the columns 21. The upper surfaces of both the assembly plate 12 and the workbench 23 have four through holes 24 arranged in a rectangular array to allow the columns 21 to pass through. The second adjustment assembly includes a second threaded post 40 fixedly installed at the lower end of the column 21, and a third adjusting nut 41 and a fourth adjusting nut 42 respectively threaded onto the surface of the second threaded post 40. The through holes 24 allow the second threaded post 40 to pass through. When the four columns 21 are vertically inserted into the through holes 24 of the assembly plate 12, the lower end of the column 21 passes through the through holes 24 through the second threaded post 40. At this time, the workbench 23 will contact the assembly plate 12. The third adjusting nut 41 and the fourth adjusting nut 42 are fixed to the upper and lower surfaces of the assembly plate 12 and the workbench 23 respectively. By adjusting the height of the third adjusting nut 41 and the fourth adjusting nut 42, the parallelism between the workbench 23 and the pressure plate 22 can be precisely adjusted, solving the problem that traditional welded frames are difficult to level quickly, thus facilitating installation.

[0034] Reinforcing ribs 50 are fixedly installed on all four sides of the base 11. The upper end of the reinforcing ribs 50 is fixedly connected to the lower surface of the mounting plate 12. The design of the reinforcing ribs 50 on the sides of the base 11 improves the overall compressive strength and ensures the rigidity of the frame under high pressure.

[0035] The positioning structure is set on the upper surface of the assembly plate 12 for positioning the worktable 23. The positioning structure includes a positioning pin 60 fixedly installed on the upper surface of the assembly plate 12 and a positioning hole 61 opened on the lower surface of the worktable 23. The positioning pin 60 and the positioning hole 61 are compatible. When the worktable 23 is installed, the positioning pin 60 will be inserted into the positioning hole 61. By utilizing the cooperation between the positioning pin 60 and the positioning hole 61, the worktable 23 does not need to be repeatedly calibrated during installation, ensuring the initial positional accuracy with the pressure plate 22 and reducing debugging time.

[0036] Specifically, the working principle and operation method of this utility model are as follows:

[0037] The first threaded post 31 on the bottom corner 30 is passed through the through hole of the base plate 10, and the first adjusting nut 32 and the second adjusting nut 33 (located on the upper and lower surfaces of the base plate 10, respectively) are tightened to form a clamping and fixing.

[0038] Adjusting the relative height of the first adjusting nut 32 and the second adjusting nut 33 can change the supporting force of the bottom corner 30 on the base plate 10, thereby coarsely adjusting the levelness of the base plate 10, ensuring the overall stability of the base, and adapting to uneven ground conditions.

[0039] The column 21 is rigidly connected to the top plate 20 to form the vertical support structure of the main frame;

[0040] Pressure plate 22 sliding guide: The pressure plate 22 is sleeved on the column 21 and slides up and down along the column 21 by the hydraulic cylinder to complete the pressing action;

[0041] Precise adjustment of the worktable parallelism:

[0042] The second threaded post 40 at the lower end of the column 21 passes through the through hole 24 of the assembly plate 12 and the worktable 23, and is locked by the third adjusting nut 41 (located on the upper surface of the assembly plate 12) and the fourth adjusting nut 42 (located on the lower surface of the worktable 23);

[0043] Rotating the third adjusting nut 41 and the fourth adjusting nut 42 can individually adjust the extension length of the second threaded post 40 of each column 21, thereby changing the local height of the worktable 23 and realizing fine adjustment of the parallelism between the worktable 23 and the pressure plate 22 (such as compensating for machining errors or deformation).

[0044] Rapid calibration of positioning structure

[0045] Positioning pin 60 mates with positioning hole 61:

[0046] The positioning pin 60 on the assembly plate 12 is embedded in the positioning hole 61 at the bottom of the worktable 23 to ensure that the worktable 23 is aligned with the initial position of the pressure plate 22 during installation, thus avoiding repeated adjustments.

[0047] After positioning, further fine-tuning is performed using the second adjustment component, reducing debugging time.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
