Description

Technical Field

[0001] This utility model relates to the technical field of bed connecting parts, specifically to a bed connecting bolt for a gantry machining center. Background Technology

[0002] In gantry machining centers, traditional connecting components are mostly connected by welding or riveting. While these methods can meet the connection requirements to a certain extent, they also present many inconveniences in actual operation.

[0003] Traditional welding or riveting methods suffer from problems such as inconvenient installation and disassembly, insufficient connection reliability, difficulty in reuse, poor adaptability, difficulty in error adjustment, and difficulty in quality control. Although existing technologies also use bolted connections, bolted connections cannot solve the problem of straightness errors caused by machined errors in the machine bed. Utility Model Content

[0004] To address the aforementioned problem—that existing bed connection methods are insufficient to resolve straightness errors caused by bed machining errors—this invention proposes a bed connection bolt for a gantry machining center. The bolt comprises an upper bed and a lower bed. A hollow bolt is threaded onto the lower bed, abutting against the upper bed. An external hexagonal bolt passes through the hollow bolt and is threaded onto the upper bed.

[0005] A further feature of this invention is that a thin nut is threaded onto the hollow bolt, and the thin nut is used to fasten the hollow bolt.

[0006] The beneficial effects of this utility model are as follows:

[0007] The upper and lower beds can be connected and fixed using hex bolts. At the same time, the hollow bolts can be used to adjust the relative position of the upper and lower beds. That is, by turning the hollow bolts, the upper bed can be lifted up. Therefore, when there is a straightness error in the contact surface of the upper or lower bed due to machining errors, the straightness between the two beds can be adjusted by adjusting the hollow bolts, thereby ensuring machining accuracy.

[0011] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0012] This utility model discloses a connecting bolt for the bed of a gantry machining center, comprising an upper bed 1 and a lower bed 2, both of which have a plurality of corresponding threaded holes. The threaded holes on the upper bed 1 are smaller than those on the lower bed 2.

[0013] A hollow bolt 3 is threaded into the threaded hole of the lower bed 2. The end of the hollow bolt 3 away from the nut abuts against the upper bed 1. The hollow bolt 3 has a through hole along its axial direction. The diameter of the through hole is coaxial with and equal to the diameter of the threaded hole on the upper bed 1. An external hexagon bolt 4 is inserted in the through hole. The external hexagon bolt 4 is threaded into the threaded hole on the upper bed 1. Thus, the upper bed 1 and the lower bed 2 can be fixedly connected by the external hexagon bolt 4.

[0014] The hollow bolt 3 is also threaded with a thin nut 5. The thin nut 5 is located between the nut of the hollow bolt 3 and the lower bed 2. By rotating the thin nut 5, it moves towards the lower bed 2, and when it comes into contact with the lower bed 2, it can achieve the fastening effect on the hollow bolt 3.

[0015] It should be noted that the threaded holes on the lower bed 2 and the hollow bolts 3 are both designed with fine threads. This allows for more precise adjustment of the hollow bolts 3.

[0016] When the contact surfaces of the upper bed 1 and the lower bed 2 are tilted due to machining errors, the hollow bolt 3 on the lower side of the upper bed 1 can be rotated to lift the upper bed 1 upwards, thereby adjusting the relative position of the upper bed 1 and the lower bed 2, compensating for part size deviations, and reducing the requirements for bed machining accuracy.

[0017] In summary, this utility model uses hexagonal bolts 4 to connect and fix the upper bed 1 and the lower bed 2. Simultaneously, the hollow bolts 3 allow for adjustment of the relative positions of the upper bed 1 and the lower bed 2; that is, by tightening the hollow bolts 3, the upper bed 1 can be lifted. Furthermore, when the straightness of the contact surface of the upper bed 1 or the lower bed 2 is incorrect due to machining errors, the straightness between the two beds can be adjusted by adjusting the hollow bolts 3, thereby ensuring machining accuracy.

[0018] Although the present invention has been described with reference to preferred embodiments, various modifications can be made to it and components can be replaced with equivalents without departing from the scope of the present invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0019] In the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to those processes, articles, or apparatus / devices.

[0022] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings.
