Description

Technical Field

[0001] This utility model belongs to the technical field of press debugging fixtures, and particularly relates to a press leveling support base. Background Technology

[0002] The existing Chinese patent database discloses a patent entitled "A Leveling Device for H-beam Flange Plates of a Press", application number CN201320413364.3, application date 2013-07-12. This device for leveling H-beam flange plates of a press includes a steel support frame. The steel support frame includes a base plate. A first base, a second base, a third base, and a fourth base are symmetrically fixedly connected within four quadrants of the center line of the base plate. The four bases have the same structure, all being "L"-shaped. A left connecting plate is fixedly connected to the inner side of the first and second bases, and a right connecting plate is fixedly connected to the inner side of the third and fourth bases. The gap between the right connecting plate and the left connecting plate is greater than the wall thickness of the H-beam. The upper planes of the right connecting plate, the left connecting plate, the first base, the second base, the third base, and the fourth base are located in the same horizontal plane. This utility model has a simple structure and is easy to use. The H-beam is inserted into the gap between the left and right connecting plates, and the press is operated to make the hammer head level the flange of the H-beam. This not only improves the service life of the workbench, but also has a good leveling effect and improves work efficiency.

[0003] In existing technologies, the press base may not be level during use, which leads to additional friction between internal parts of the press, increases the equipment failure rate, and affects machining accuracy. This paper aims to propose a press leveling support base that ensures the levelness of the press during operation and improves machining accuracy by individually supporting and adjusting each corner of the press base. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to adjust the level of the press to avoid wear of the internal parts of the press and improve the processing accuracy and quality. In order to improve its shortcomings, this utility model provides a press leveling support base.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A press leveling support base includes a pre-embedded base, a connecting seat fixedly installed inside the base, an adjusting screw threaded into the connecting seat, one end of the adjusting screw passing through the side of the base and having a rotating head installed thereon, and the other end connected to a lower wedge block, the upper surface of the lower wedge block being inclined downwards, an upper wedge block being connected to the lower wedge block, and the lower surface of the upper wedge block being fitted against the upper surface of the lower wedge block.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: due to the coordinated arrangement of the adjusting screw, the upper wedge block and the lower wedge block, the position of the lower wedge block can be changed by rotating the adjusting screw, thereby adjusting the height of the upper wedge block. The device is placed on the corner of the base of the press, thereby completing the horizontal adjustment of the press, avoiding wear of the internal parts of the press and improving the processing accuracy and quality. This device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, the upper wedge block has a hemispherical groove, in which a support plate is embedded. The lower surface of the support plate has a hemispherical protrusion that mates with the hemispherical groove. The support plate has a first through hole, the upper wedge block has a second through hole coaxial with the first through hole, and the lower wedge block has an oblong hole. A pull rod is inserted into the second through hole. The upper free end of the pull rod is located in the first through hole and is screwed with a locking nut. The lower free end of the pull rod passes through the oblong hole and the bottom of the base in sequence and is screwed with a locking nut.

[0009] As a preferred embodiment, the base has a horizontal groove on its side, and the lower wedge block has a guide block integrally formed on its side. The inner surface of the guide block has a protruding strip that is slidably connected to the groove.

[0010] As a preferred embodiment, the free end of the adjusting screw is rotatably connected to the side of the lower wedge block.

[0011] As a preferred embodiment, the base is U-shaped, and the side of the upper wedge block abuts against the inner surface of the ear plate section of the base. Attached Figure Description

Detailed Implementation

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2As shown, a leveling support base for a press includes a pre-embedded base 1, a connecting seat 2 fixedly installed inside the base 1, an adjusting screw 3 threadedly connected to the connecting seat 2, one end of the adjusting screw 3 passing through the side of the base 1 and having a rotating head 4 installed thereon, and the other end connected to a lower wedge block 5, the upper surface of the lower wedge block 5 being inclined downwards, an upper wedge block 6 being connected to the lower wedge block 5, and the lower surface of the upper wedge block 6 being fitted against the upper surface of the lower wedge block 5. The upper wedge block 6 has a hemispherical groove 7, within which a support plate 8 is embedded. The lower surface of the support plate 8 has a hemispherical protrusion 9 that mates with the hemispherical groove 7. The support plate 8 has a first through hole 10. The upper wedge block 6 has a second through hole 11 coaxial with the first through hole 10. The lower wedge block 5 has a waist-shaped hole 12. A pull rod 13 is inserted into the second through hole 11. The upper free end of the pull rod 13 is located within the first through hole 10 and is screwed with a locking nut 14. The lower free end of the pull rod 13 passes sequentially through the waist-shaped hole 12 and the bottom of the base 1, and is screwed with a locking nut 14. A horizontal sliding groove 15 is formed on the side of the base 1. A guide block 16 is integrally formed on the side of the lower wedge block 5. The inner surface of the guide block 16 has a protruding strip 17 that slidably connects to the sliding groove 15. The free end of the adjusting screw 3 is rotatably connected to the side of the lower wedge block 5. The base 1 is U-shaped, and the side of the upper wedge block 6 abuts against the inner surface of the ear plate section of the base 1.

[0017] During operation, the operator pre-buries the entire device in the underground pit, and then rotates the rotating head 4. Since the adjusting screw 3 is screwed into the connecting seat 2, the adjusting screw 3 drives the lower wedge block 5 to move horizontally. When the lower wedge block 5 moves horizontally to the right, the wedge-shaped surface of the lower wedge block 5 and the upper wedge block 6 cooperate, causing the height of the upper wedge block 6 to rise. After reaching the required height, the upper end of the pull rod 13 is locked with the locking nut 14. By setting the leveling support base at the four corners of the press base, the press can be leveled before operation, avoiding wear of the internal parts of the press and improving the processing accuracy and quality.

[0018] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
