DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-3 As shown, a horizontal calibration device for a stretching hydraulic press comprises a horizontal plate 1 and a mounting plate 2, a base 5 is fixedly connected to the middle of the top of the horizontal plate 1, a first rolling ball 6 is rollingly connected to the top of the base 5, a support plate 7 is fixedly connected to the top of the first rolling ball 6, and the support plate 7 is fixedly connected to the middle of the bottom of the mounting plate 2, a telescopic electric cylinder 3 is arranged at the four corners of the top of the horizontal plate 1, a connecting rod 10 is fixedly connected to the output end of the telescopic electric cylinder 3, a contact ball 11 is fixedly connected to the top of the connecting rod 10, and the contact ball 11 is in contact with the bottom end of the mounting plate 2, a level is arranged on the right side of the top of the horizontal plate 1, a controller is arranged inside the level, and the output end of the controller is electrically connected to the input end of the telescopic electric cylinder 3;

[0022] When the mounting plate 2 is in an uneven state, the telescopic electric cylinders 3 at various positions work, and the height of the contact ball 11 is changed through the connecting rod 10 until the mounting plate 2 is horizontal. In the process of adjusting the level of the mounting plate 2, the first rolling ball 6 rotates on the top of the base 5 to cooperate with the adjustment of the mounting plate 2. When the hydraulic press acts on the mounting plate 2, the horizontal plate 1 not only supports the four corners of the mounting plate 2 through the telescopic electric cylinder 3, the connecting rod 10 and the contact ball 11, but also supports the center of the mounting plate 2 through the base 5, the first rolling ball 6 and the support plate 7, which greatly improves the bending strength of the mounting plate 2 and avoids deformation of the mounting plate 2 and affects the normal operation of the equipment.

[0023] Specifically, Figure 2 As shown, the four corners of the bottom end of the mounting plate 2 are fixedly connected with pads 12, and the bottom end of the pad 12 is against the contact ball 11. The outer surfaces of the contact ball 11 and the pad 12 are smooth. The contact ball 11 and the pad 12 are made of high-hardness steel. The contact ball 11 supports the four corners of the mounting plate 2 through the pad 12, which increases the supporting area of ​​the mounting plate 2 and further improves the bending strength of the mounting plate 2. The smooth contact ball 11 and the pad 12 reduce the wear of the friction assembly, and the contact ball 11 and the pad 12 made of high-hardness steel avoid deformation themselves.

[0024] Specifically, Figure 1, Figure 2 and Figure 3 As shown, four elastic telescopic rods 4 are arranged around the base 5, and the upper and lower ends of the elastic telescopic rods 4 are fixedly connected with the second rolling ball 15, and the outer side of the second rolling ball 15 is rollingly connected with a fixing seat 16, and the fixing seats 16 at the upper and lower ends of the elastic telescopic rods 4 are respectively fixedly connected with the mounting plate 2 and the horizontal plate 1, and the horizontal plate 1 is connected to the mounting plate 2 through the elastic telescopic rods 4, which avoids the first rolling ball 6 from rotating horizontally in the base 5, thereby avoiding the misalignment of the contact ball 11 and the mounting plate 2, and maintaining the state of the mounting plate 2, and the second rolling ball 15 rolls in the fixing seat 16 to cooperate with the changes of the mounting plate 2.

[0025] Specifically, Figure 2 As shown, the top of the telescopic electric cylinder 3 is fixedly connected to a plurality of support rods 8, the tops of the plurality of support rods 8 are fixedly connected to a limiting ring 9, and the limiting ring 9 is sleeved on the outside of a connecting rod 10. The connecting rod 10 is restricted by the support rods 8 and the limiting ring 9, thereby improving the bending strength of the connecting rod 10.

[0026] Specifically, Figure 3 As shown, ear plates 13 are fixedly connected to the four sides of the bottom end of the telescopic electric cylinder 3, bolts 14 are arranged inside the ear plates 13, and the bottom of the bolts 14 are threadedly connected to the horizontal plate 1. The telescopic electric cylinder 3 is fixed to the horizontal plate 1 through the ear plates 13 and the bolts 14. The telescopic electric cylinder 3 can be removed from the horizontal plate 1 by removing the bolts 14, so that the telescopic electric cylinder 3, the connecting rod 10 and the contact ball 11 can be replaced conveniently.

[0027] Working principle: The level instrument detects that the mounting plate 2 is not in a horizontal state, the controller controls the telescopic electric cylinder 3 to work, the connecting rod 10 moves along the limit ring 9, the height of the contact ball 11 is changed through the connecting rod 10, and the contact ball 11 acts on the pad 12 to adjust the mounting plate 2 horizontally until the mounting plate 2 is in a horizontal state;

[0028] When the hydraulic press is working, the mounting plate 2 is subjected to force, and the horizontal plate 1 not only supports the four corners of the mounting plate 2 through the telescopic electric cylinder 3, the connecting rod 10, the contact ball 11 and the pad 12, but also supports the central part of the mounting plate 2 through the base 5, the first rolling ball 6 and the support plate 7, so as to enhance the strength of the mounting plate 2;

[0029] When inspecting the telescopic electric cylinder 3 , the connecting rod 10 and the contact ball 11 , the telescopic electric cylinder 3 can be removed from the horizontal plate 1 by removing the bolts 14 .

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
