Description

Technical Field

[0001] The invention belongs to the technical field of CNC machine tool processing auxiliary tools, and in particular relates to an adjustable mechanical bracket for installing a deep cavity guide rail. Background Art

[0002] When assembling a floor-standing boring and milling machine, in order to adjust the center of gravity, a slidable counterweight mechanism, a heavy hammer, needs to be installed inside the column cavity. To meet the assembly requirements, a guide rail is usually installed for sliding adjustment of the heavy hammer to ensure the stability of the equipment during operation. The straightness of the guide rail during installation is required to be within 0.03mm in total length. During the traditional installation process, due to the deep and long column cavity, the guide rail positioning cannot be effectively observed during actual operation, making it difficult to ensure the straightness of the guide rail, and the installation efficiency is low, making it difficult to adjust later. Therefore, a deep-cavity heavy hammer guide rail installation tool is needed for the rapid installation and precise positioning of the heavy hammer guide rail. Summary of the invention

[0003] The present invention aims at the above-mentioned problems, makes up for the deficiencies of the prior art, and provides an adjustable mechanical bracket for deep cavity guide rail installation; the present invention changes the position of the weight guide rail by fixing it inside the deep cavity of the column, thereby improving the straightness of the weight guide rail installation and improving the installation efficiency.

[0004] To achieve the above purpose, the present invention adopts the following technical solution.

[0005] The present invention provides an adjustable mechanical bracket for installing a deep cavity guide rail, characterized in that it includes a pressing plate, a plurality of claws are connected to the bottom of the pressing plate, all of the claws jointly push the bottom plate against the bottom of the pressing plate, a lifting and adjusting mechanism is connected to the top of the pressing plate, the liftable part of the lifting and adjusting mechanism is connected to a tray, at least one rolling mechanism is provided on the tray, and the rolling mechanism can push the guide rail placed above by rolling.

[0006] Furthermore, the lifting and adjusting mechanism includes a support rod, an internal screw, and an adjusting nut. The support rod is fixed to the upper part of the pressure plate and has an internal thread. The internal screw, as the liftable part of the lifting and adjusting mechanism, is rotated inwardly and placed inside the support rod. The adjusting nut is threadedly sleeved on the internal screw for tightening the adjusted internal screw.
