Description

Technical Field

[0001] This utility model provides a foundation guide rail, and particularly relates to a foundation guide rail for CNC machine tool processing. Background Technology

[0002] In the field of CNC machine tool machining, the ground guide rail is a key basic component that ensures the stable operation of the equipment. Its function is to provide precise guidance for the moving parts of the machine tool, bear the load, and maintain machining accuracy. Traditional ground guide rails often adopt an integrated cast-in-place or simply spliced ​​track structure. The basic structure is mostly a single track slab laid directly on the ground foundation and connected to the ground through simple embedded parts. While it can achieve basic guiding functions, it has obvious shortcomings: On the one hand, the connection stability between the track plate and the ground is poor, and conventional embedded parts alone are insufficient to cope with the vibration and load impact during machine tool operation, which can easily lead to track deviation and loosening, affecting machining accuracy; on the other hand, the track length is fixed and cannot be flexibly adjusted according to the machine tool layout, resulting in poor expandability. Moreover, the frame structure for connecting with external machine tools is rudimentary, mostly rigid direct connection, lacking buffer and stable support design, making it difficult to adapt to the installation requirements of different machine tool models. At the same time, the locking structure is simple and does not consider buffering, anti-slip and other functions, which cannot guarantee the connection reliability under long-term operation, resulting in a short overall service life of the guide rail, high maintenance costs, and difficulty in meeting the high-precision and flexible CNC machine tool processing needs. Utility Model Content

[0003] In order to solve the above problems, this application provides a foundation guide rail for CNC machine tool processing, which solves the problems of poor stability, weak expandability and insufficient buffering of traditional guide rails, and realizes high-precision and flexible processing.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a foundation guide rail for CNC machine tool processing, including a ground, wherein a track plate is connected to the interior of the ground through a plurality of preset clamping plates, and an expansion connecting frame is movably engaged above the track plate; The track plate and the preset card plate are provided with a locking structure; the track plates are continuously connected by connecting plates.

[0005] Preferably, the preset plate is embedded in the ground, and the surface of the preset plate has a slot adapted to the track plate. The track plate is engaged with the preset plate through the slot, and the slot has a pair of symmetrically distributed mounting buckles inside. Preferably, the extension connection frame includes a frame with a triangular support structure. The bottom of the frame has a locking part adapted to the track plate, which is movably engaged with the track plate. The side of the frame has a mounting groove for connecting an external machine tool. The mounting groove is composed of several vertically staggered longitudinal support rods and transverse support rods. Preferably, the locking structure includes a locking block located at the bottom of the track plate and clamping blocks located on both sides of the track plate and placed on the locking block. The locking block and clamping blocks are fixedly connected by locking bolts, and a rubber pad is provided below the locking block and placed inside the locking groove. Preferably, both ends of the connecting plate are provided with connectors adapted to the ends of the track plate. The connectors are fixedly connected to the ends of the track plate by at least one method, such as bolts or buckles, to achieve continuous splicing of the track plate. Preferably, the frame of the extension connecting frame is made of welded or integrally formed metal profiles, and the surface of the frame is coated with an anti-rust coating. Preferably, a pad is provided between the locking block and the track plate in the locking structure; the inner wall of the rubber pad has anti-slip textures to improve locking stability.

[0006] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This invention embeds a pre-set clamping plate in the ground, utilizing its surface grooves that adapt to the track plate and internal mounting buckles. A locking structure, consisting of a bottom clamping block, two side clamping blocks, and locking bolts, along with a rubber pad under the clamping block and a pad between the clamping block and the track plate, ensures a stable connection between the track plate and the pre-set clamping plate.

[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0013] like Figure 1 and Figure 2As shown, a CNC machine tool machining foundation guide rail is based on the ground 1. An internal pre-embedded clamping plate 2 connects to a track plate 3. The surface of the pre-embedded clamping plate 2 has a groove 21 adapted to the track plate 3 and symmetrically installed buckles 22. The track plate 3 and the pre-embedded clamping plate 2 are connected by a locking structure 5, which includes a bottom clamping block 51 and two side clamping blocks 52 (fixed by locking bolts). A rubber pad 53 is placed under the clamping block 51 in the groove 21, and a pad 54 is also provided between the clamping block 51 and the track plate 3. The clamping block 51 and the clamping block 52 are fixedly connected by locking bolts that penetrate themselves and correspond to the connecting buckles 22. An extended connecting frame 4 with a movable locking triangular support structure above the track plate 3 has a frame 41 made of welded metal profiles. It is integrally molded with an anti-rust coating. The bottom is provided with a snap-fit ​​part 42 that is compatible with the track plate 3. The side mounting groove 43 is composed of vertically intersecting longitudinal and transverse support rods. The track plates 3 are continuously spliced ​​together by bolts or buckles through connecting plates 6 with matching connectors at both ends.

[0014] In this implementation scheme, the pre-set clamping plate 2 is embedded in the ground 1 to form a stable base. Its surface groove 21 is precisely matched with the track plate 3. With the symmetrical installation of buckles 22, the displacement of the track plate is initially restricted, providing a positioning basis for subsequent connection. In the locking structure 5, the bottom clamping block 51 of the track plate 3 is embedded in the groove 21. The clamping blocks 52 on both sides are fixed to the clamping block 51 by locking bolts, so that the track plate 3 and the pre-set clamping plate 2 are tightly fitted. The elastic deformation of the rubber pad 53 absorbs the vibration and impact generated by the machine tool operation, reducing the displacement risk caused by rigid connection. At the same time, its inner wall anti-slip texture further enhances the friction. The pad 54 helps to disperse stress and avoid local deformation of the track plate 3. The multiple structures work together to ensure the stable installation of the track plate 3 and have buffering performance.

[0015] The track plates 3 are flexibly spliced ​​together using bolts or clips via the adapter connectors of the connecting plates 6. The guide rail length can be freely adjusted according to the machine tool processing site and layout requirements, significantly improving installation adaptability. The extended connecting frame 4 with the triangular support structure engages with the track plates 3 through the bottom snap-fit ​​part 42, forming a detachable and stable connection. Its frame 41 is made of welded / integrated metal profiles, ensuring high strength load-bearing capacity. The anti-rust coating extends service life. The mounting grooves 43 on the side, composed of vertically intersecting support rods, can be fixedly connected to external machine tools from multiple directions and angles, evenly distributing the complex load of the machine tool during operation to the track plates 3, enhancing the overall structural stability and anti-overturning ability. The various components form an organic whole through reasonable positions and connections, effectively solving the problems of poor stability, weak expandability, and insufficient buffering of traditional foundation guide rails, and achieving high-precision, long-life, and flexibly adaptable CNC machine tool processing support functions.

[0016] like Figure 3 and Figure 4As shown, when using this device, the preset card plate 2 is first buried in the ground 1. The card slot 21 and the mounting buckle 22 cooperate with the locking structure 5. Through the card block 51, clamping block 52, anti-slip texture on the inner wall of the rubber pad 53, and pad plate 54, the track plate 3 is stably locked onto the preset card plate 2, ensuring connection stability and buffering. The track plate 3 can be spliced ​​to a custom length using the connecting plate 6 to meet the needs of different scenarios. The extended connecting frame 4 is locked onto the track plate 3 through the locking part 42. The structural design of the triangular frame 41 and the mounting groove 43 can stably connect to the external machine tool. The anti-rust coating improves the durability of the frame. The overall structure realizes the functions of flexible installation of the foundation guide rail, stable connection, and adaptation to machine tool operation, providing reliable support for CNC machine tool processing.

[0017] In this implementation plan, during use, existing measurement and positioning technologies such as a total station are first used to plan the placement position of the pre-set clamping plate 2 on the ground 1, ensuring that its levelness and straightness meet the installation requirements. The pre-set clamping plate 2 is made of Q345B high-strength steel to ensure its load-bearing capacity after embedding. The pre-set clamping plate 2 is firmly embedded in the ground 1 through a concrete pouring process. After the concrete has cured, the clamping block 51 at the bottom of the track plate 3 is aligned with the clamping groove 21 of the pre-set clamping plate 2. An electric torque wrench is used to precisely control the tightening torque of the locking bolts, so that the clamping block 52 and the clamping block 51 are tightly fixed. At the same time, the rubber pad 53 (made of nitrile rubber, which has both oil resistance and high elasticity) fully compresses and fills the gap, realizing a stable connection between the track plate 3 and the pre-set clamping plate 2. When it is necessary to adjust the length of the guide rail, the dimensions of the splicing point of the track plate 3 are measured with a vernier caliper. The connecting plate 6 is made of 45# steel and heat-treated to enhance its comprehensive mechanical properties. The adapter connectors at both ends are quickly spliced ​​with bolts or clips. When installing the extension connection frame 4, a level is used to calibrate the verticality of the frame 41. Its metal profile is made of 6061-T6 aluminum alloy, and a triangular support structure is formed through welding or integral molding. The anchor bolts of the external machine tool are passed through the mounting slot 43, and the machine tool is fixed in place with nuts and washers. The epoxy zinc-rich anti-rust coating on the surface of the frame 41 effectively resists corrosive substances in the processing environment. During the operation of the CNC machine tool, vibration sensors monitor the vibration data of the track plate 3 and the extension connection frame 4 in real time. If any abnormality occurs, the compression of the rubber pad 53 can be adjusted or the locking bolts can be tightened to ensure that the foundation guide rail always maintains a stable operating state, providing a reliable guarantee for high-precision machining.

[0018] Specifically, in one or more feasible embodiments, when implementing this solution, the ground 1 is first leveled using a laser level to ensure that the flatness error of the installation reference surface is controlled within ±2mm; the installation holes of the preset card plate 2 are precisely drilled on the ground 1 according to the design drawings using drilling machinery. The hole depth and diameter must be compatible with the size of the preset card plate 2. The preset card plate 2, made of Q345B high-strength steel, is embedded in the hole and fixed by secondary grouting using C30 fine stone concrete. After the concrete has cured to the design strength, the dimensional accuracy of the card slot 21 is measured using vernier calipers to ensure that it matches the track plate 3. When installing the track slab 3, the HT300 gray cast iron track slab 3 is placed stably on the pre-set clamping plate 2 using hoisting equipment, so that the clamping block 51 is accurately embedded into the clamping groove (21). The locking bolt between the clamping block 52 and the clamping block 51 is tightened with a torque wrench to a preset torque (about 80-100 N·m). At the same time, a 3mm thick No. 45 steel pad 54 is installed between the clamping block 51 and the track slab 3 to ensure uniform force. The nitrile rubber pad 53 is pressed tightly against the inner wall of the clamping groove 21, and its anti-slip texture enhances the friction. During the splicing process of the track slab 3, the ends of the track slab 3 are ground with an angle grinder to ensure that the splicing surface is flat. The connecting plate 6 with the matching connectors at both ends is fixed to the ends of the track slab 3 with bolts (8.8 grade high strength bolts) or clips. After splicing, the gap of the joint is checked with a feeler gauge to ensure that it does not exceed 0.5mm. When installing the extension connection frame 4, a gantry crane and electric hoist are used to hoist the frame 41, made of 6061-T6 aluminum alloy, onto the track plate 3. The bottom locking part 42 of the frame 41 is precisely engaged with the track plate 3 using positioning pins. A level is used to monitor the levelness of the frame 41 in real time, and fine adjustments are made by adding or removing shims. The external machine tool is moved to the side of the extension connection frame 4 using a forklift or a transport trolley. The machine tool is lifted with a jack so that the machine tool's anchor bolts pass through the mounting groove 43, which is composed of vertically intersecting longitudinal and transverse support rods. Flat washers, spring washers, and nuts are installed in sequence. The nuts are tightened gradually using an electric wrench in a diagonal tightening manner. Finally, a torque wrench is used to check the torque to the design requirements (approximately 120-150 N·m). During machine tool operation, a vibration monitoring instrument is used to collect data such as vibration frequency and amplitude of the foundation guide rail in real time. When abnormal vibration signals are detected, a hydraulic puller is used to disassemble the relevant components, check the wear of the rubber pad 53 and the looseness of the locking bolts, and replace the worn rubber pad 53 or retighten the bolts in a timely manner to ensure that the foundation guide rail is always in a stable and reliable working state, providing a solid guarantee for the high-precision machining of CNC machine tools.

Therefore, the scope of protection of the present invention should be determined by the claims.
