Description

Technical Field

[0001] The utility model relates to the technical field of CNC machine tool components, and specifically relates to a guide rail mechanism of a CNC machine tool. Background Technique

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. The CNC machine tool integrates technologies such as machinery, automation, computer, and microelectronics, solves the processing problems of complex, precise, and small-batch parts, and is a flexible and high-performance automated machine tool. Currently, a CNC machine tool is composed of multiple components, including a guide rail, which is a groove or ridge made of metal or other materials and is a device that can bear, fix, guide a moving device or equipment and reduce its friction.

[0003] The utility model with the publication number of CN205990128U in the prior art relates to a guide rail mechanism. By improving the support performance of the guide rail, coordinating with the flexibility during the operation of the attached anti-falling device, and balancing the coordination of the guide wheel actions, the running stability, balance, and safety and reliability in the static state of the climbing frame are improved. Moreover, by using channel steel group welding, the manufacturing process is reduced, and the production efficiency is greatly improved.

[0004] However, the above device still has the following problems when in use: its guide rail mechanism is a fixed guide rail structure design, and the length of its own guide rail cannot be adjusted. Therefore, it is impossible to adjust the length of the guide rail according to the displacement requirements of different moving devices, so the actual applicable scenarios are too single.

[0006] Aiming at the deficiencies of the prior art, the utility model provides a guide rail mechanism of a CNC machine tool, which solves the problems raised in the background technique.

[0007] (II) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solution: A guide rail mechanism of a CNC machine tool includes a mounting frame. On the front and rear side walls of the upper end of the mounting frame, a set of limit grooves are respectively opened. On both sides of the top end of the mounting frame, a long guide rail block is slidably mounted respectively. In the middle of the top end of the mounting frame, a set of short guide rail blocks is slidably mounted. The set of short guide rail blocks consists of three and is arranged in a horizontally equidistant and fitting manner. There is a mounting frame of a guide rail mechanism as a whole. At both ends of the mounting frame, two non-removable but adjustable-position long guide rail bodies are slidably mounted. At the same time, in the middle of the mounting frame, three removable short guide rail bodies are slidably mounted. By disassembling and assembling the short guide rail bodies in the middle and moving the long guide rail bodies on both sides, multiple guide rail bodies can form a complete guide rail. The length of its own guide rail can be adjusted, and thus the length of the guide rail can be adjusted according to the displacement requirements of different moving devices, and the actual applicable scenarios are relatively rich.

[0009] As a further solution of the utility model: a set of the limiting grooves are two and are arranged symmetrically up and down. The inner side wall of the long guide rail block is provided with bumps that are slidably connected to the four limiting grooves. The long guide rail block can slide on the mounting rack but cannot be detached. The outer contours of the sides of the three short guide rail blocks are the same as those of the sides of the long guide rail block. After combining and fitting multiple guide rail blocks, a coherent and flat combined guide rail can be formed.

[0010] As a further solution of the utility model: a groove is opened in the middle of the bottom wall of the mounting rack. At both ends of the top wall of the groove, a strip-shaped groove is opened respectively. Two fastening screws are slidably mounted symmetrically in the strip-shaped grooves. The tops of the two fastening screws at the same end are threadedly connected to the same long guide rail block. A set of short guide rail blocks are clamped between the opposite ends of the two long guide rail blocks. A threaded hole is opened at both ends of the bottom wall of the long guide rail block. The top end of the fastening screw is threadedly connected to the threaded hole. The bottom end of the fastening screw is slidably connected to the top wall of the groove, and a dial is fixedly connected to the middle position at the bottom end of its head. A fastening screw structure is arranged at the bottom of its long guide rail body. The dial can be held to rotate the fastening screw to realize the fastening of the long guide rail body. That is, the middle short guide rail body can be clamped by the two long guide rail bodies on both sides, and the two long guide rail bodies can be fastened by the fastening screws, so as to fix multiple short guide rail bodies on the mounting rack and prevent the short guide rail bodies from falling off during use.

[0011] As a further solution of the utility model: a stopper is fixedly connected to each end of the mounting rack. The two stoppers are arranged symmetrically and a support frame is fixedly connected to the middle of the bottom wall. The bottom end of the support frame is fixedly connected to a mounting base. Two mounting holes are opened symmetrically in the front and back between the upper and lower side walls of the mounting base. The overall guide rail mechanism can be fixedly installed on the corresponding working station of the numerical control machine tool through the mounting holes on the two mounting bases and the mounting components.

The length of the guide rail itself can be adjusted, and thus the length of the guide rail can be adjusted according to the displacement requirements of different moving devices. The actual applicable scenarios are relatively rich.

[0014] 2. In the present utility model, a fastening screw structure is provided at the bottom of the long guide rail body. The fastening screw can be rotated by holding the dial block, so as to fasten the long guide rail body. That is, the middle short guide rail body can be clamped by the two long guide rail bodies on both sides, and the two long guide rail bodies can be fastened by the fastening screw, so as to fix a plurality of short guide rail bodies on the mounting rack and prevent the short guide rail bodies from falling off during use.
