Problems solved by technology

The guide elements (mostly 4 pieces) of the auxiliary guide part need to be connected with the slider and the lower beam at the same time. The positioning holes or installation holes of the above parts require high machining accuracy, and it is generally difficult to ensure their position consistency. It is easy to hold back when installing the guide elements Strength, affecting the guiding accuracy
Cancellation of the positioning of the slider or the lower beam (connected with only a few screws) results in a significant reduction in stiffness and thus indirectly affects the guiding accuracy
Due to the limitation of the structure, most of the auxiliary guides are cantilever structures, the guide length is short and the rigidity is poor

Embodiment 1

[0019] like figure 1 , figure 2 and Figure 5 As shown, the precision cylindrical guide structure of this press is composed of two parts, the main guide and the auxiliary guide. Column 8, auxiliary guide column 10 and auxiliary guide element; the main sleeve 1 is connected with the upper beam 9 through screws, the lower end of the main column 2 is connected with the upper end surface of the connection plate 6 through screws, and the lower end surface of the connection plate 6 is connected with the slider 7, like figure 1 , image 3 and Figure 4 As shown, between the main column 2 and the main sleeve 1, there is a main guiding element composed of a cage 3 and a ball 4, and the ball 4 is evenly installed in the cage 3 from top to bottom. The diameter of 4 is not less than half of the difference between the inner diameter of the main sleeve 1 and the outer diameter of the main post 2, forming a zero gap or a small interference, and the sealing gland A 5 is connected to the...

Embodiment 2

[0023] This embodiment is basically the same as Embodiment 1, the difference is that, as Image 6 and Figure 7 As shown, the auxiliary guide element is a guide shoe 17, and the guide shoe 17 is installed between the auxiliary guide post 10 and the round table 71 with screws, and is located at the upper and lower ends of the round table 71. There is a small gap between the guide shoe 17 and the auxiliary guide post 10. It is filled with lubricating oil under a certain pressure, and the upper and lower ends of the round platform 71 are provided with a cover 18, which limits the displacement of the guide shoe 17 and prevents the leakage of the lubricating oil. The guiding structure is in surface contact when bearing a load and has good rigidity. Medium press.

[0024] In order to further improve the rigidity of the equipment, the bottom surface of the round table 71 is lower than the feeding line, so that the guiding distance is large, thereby improving the rigidity of the equi...

Abstract

The utility model discloses a press precision cylindrical guide structure, and belongs to the technical field of press machine. The press precision cylindrical guide structure comprises a dominant guide portion and an auxiliary guide portion. The dominant guide sleeve is connected with upper beam through a screw. The upper surface of connection plate is connected with the lower portion of the dominant guide pillar and the lower surface of the connection plate is connected with a slider. The dominant guide component, which comprises a holder A and roll balls B, is disposed between the dominant guide pillar and the dominant guide sleeve. Multi-row roll balls B are uniformly arranged from top to bottom in the holder A. The diameter of the roll balls B is no less than half of the difference between the inner diameter of the dominant guide sleeve and the outer diameter of the dominant guide pillar. The sealing gland A is connected to the lower surface of the dominant guide sleeve through a screw. An auxiliary guide component is disposed between the auxiliary guide pillar and the slider. The auxiliary guide pillar is connected to the stand post which is respectively connected with the upper beam and the lower beam through a screw. The press precision cylindrical guide structure has the advantages of being capable of improving the guide precision of press machine, improving the partial load resistance of press machine, and being excellent in rigidity.

Description

technical field [0001] The invention relates to a precise cylindrical guide structure of a press, which belongs to the technical field of presses. Background technique [0002] For presses with cylindrical guides, the guide elements are mostly sliding bearings, which restricts the improvement of guide accuracy due to the existence of motion gaps. The guide elements (mostly 4 pieces) of the auxiliary guide part need to be connected with the slider and the lower beam at the same time. The positioning holes or installation holes of the above parts require high machining accuracy, and it is generally difficult to ensure their position consistency. It is easy to hold back when installing the guide elements strength, affecting the guiding accuracy. Cancellation of the positioning of the slide or the lower beam (connected with only a few screws) results in a significant reduction in stiffness, which indirectly affects the guiding accuracy. Due to the limitation of the structure, ...
