Description

Technical Field

[0001] This utility model relates to the field of machine tool guideway technology, and in particular to an intelligent temperature control and deformation suppression device for machine tool guideways. Background Technology

[0002] In the machining process of modern high-speed CNC machine tools, the impact of thermal deformation on the machining accuracy of CNC machine tools is receiving increasing attention. In order to achieve rapid positioning, the moving parts of the machine tool need to move rapidly on the guide rail. The friction between the moving parts of the machine tool and the guide rail will generate a lot of frictional heat, which will cause thermal deformation of the guide rail. The bed guide rail is the reference for the relative movement position of the main components of the machine tool, and its accuracy directly affects the relative positional relationship between the forming movements of the machine tool.

[0003] A search revealed Chinese Patent Publication No. CN116690302A, which discloses a constant temperature control system, control method, and CNC machine tool for an integral bed guide rail. The system includes a cooling chamber installed within the base of the integral bed guide rail. The cooling medium transfers the heat generated by friction on the guide rail away from the guide rail. This technical solution achieves intelligent temperature control and cooling by setting a cooling chamber and temperature sensor on the machine tool guide rail base. However, during use, the machine tool's moving slider and guide rail continuously generate metal shavings and running dust during high-speed operation. Existing technologies rely solely on the cooling medium for heat conduction without a cleaning structure, leading to the continuous accumulation of contaminants on the guide rail surface. This accumulated impurities alter the surface roughness of the guide rail, exacerbating frictional heat generation. Frictional heat accelerates the decomposition of the lubricating oil film. Existing technologies lack lubrication compensation; as lubrication effectiveness decreases, the friction coefficient increases, further aggravating heat accumulation and ultimately causing uncontrolled thermal deformation of the guide rail, making it difficult to meet the stable operation requirements of the machine tool's precision. Therefore, an intelligent temperature control and deformation suppression device for machine tool guide rails is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent temperature control and deformation suppression device for machine tool guideways to solve the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A machine tool guide rail intelligent temperature control and deformation suppression device includes:

[0007] A guide rail base is a structure used to support the guide rail and moving parts.

[0008] The top of the guide rail base is provided with a machine tool guide rail, and the outer side of the machine tool guide rail is provided with a machine tool moving slider extending to its top.

[0009] The guide rail base is equipped with a cooling temperature control component extending to its outer side, which is used to cool the machine tool guide rail through the guide rail base;

[0010] The outer side of the guide rail base is provided with connecting components located on both sides of the machine tool moving slider and movably connected thereto, for providing support and connection purposes;

[0011] The connecting component is provided with cleaning components on both the front and rear sides that extend to its inner side and fit against the machine tool guide rail, for cleaning impurities adhering to the machine tool guide rail.

[0012] The top of the connecting component is provided with a lubrication component that extends through to its inner side and fits against the machine tool guide rail, which is used to lubricate the machine tool guide rail when the machine tool moves the slider.

[0013] Preferably, the cooling temperature control component includes a cooling channel with a serpentine structure designed inside the guide rail base. Temperature sensors extending to the outside are fixedly installed on the left and right sides inside the guide rail base. Two temperature sensors are respectively installed adjacent to each other at both ends of the cooling channel. The top of the guide rail base has collection grooves located on both sides of the machine tool guide rail for collecting impurities for subsequent cleaning.

[0014] Preferably, the connecting assembly includes a connecting frame extending to the outside of the guide rail base. There are two connecting frames, which are movably installed on the left and right sides of the machine tool moving slider. A positive magnetic block extending into the side of the connecting frame near the machine tool moving slider is fixedly installed. A mounting bolt that is threaded to the machine tool moving slider is threadedly installed on one side of the connecting frame. A protrusion that is slidably connected to the guide rail base is fixedly installed on the inner side of the connecting frame. Embedding grooves are provided on both the front and rear sides of the connecting frame.

[0015] Preferably, the cleaning assembly includes an embedded plate, which is movably mounted on the outside of the connecting frame and extends into the embedded groove. A cleaning cotton brush extending into the collection groove and fitting against the machine tool guide rail is fixedly installed at one end of the embedded plate located inside the embedded groove. A locking bolt is threaded onto the outside of the connecting frame, penetrating its interior and threadedly connected to the embedded plate.

[0016] Preferably, the lubrication assembly includes an oil reservoir, which is located on the top of the connecting frame. A sponge brush that penetrates the inner side of the connecting frame and fits against the machine tool guide rail is fixedly installed on the inner bottom wall of the oil reservoir. A cover plate is threadedly installed on the top of the oil reservoir by fixing bolts, and an oil injection pipe communicating with the oil reservoir is fixedly installed on the top of the cover plate.

[0017] Preferably, the connecting frame has a U-shaped structure design, and a negative magnetic block that fits against the positive magnetic block is fixedly installed inside the machine tool moving slider. The front and rear sides of the guide rail base are provided with sliding grooves that are adapted to the moving trajectory of the protrusion.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This intelligent temperature control and deformation suppression device for machine tool guideways uses a linkage design between the machine tool moving slider, connecting components, and cleaning components. The collection groove on the guideway base and the cleaning brush work together. When the machine tool moving slider reciprocates, the cleaning brush moves laterally along the surface of the machine tool guideway, removing metal debris adhering to the surface of the machine tool guideway and impurities accumulated in the collection groove in real time. This effectively avoids local heat accumulation and decreased contact stiffness caused by impurity friction, thereby avoiding the risk of deformation caused by impurity accumulation.

[0020] This intelligent temperature control and deformation suppression device for machine tool guideways utilizes the synergistic effect of the machine tool moving slider, connecting components, and lubrication components. The sponge brush in the oil reservoir continuously absorbs lubricating oil through capillary action and evenly coats the machine tool guideway surface with lubricating oil during the movement of the machine tool moving slider. This design can dynamically maintain the integrity of the lubrication film between the machine tool guideway and the machine tool moving slider, reduce the coefficient of sliding friction, reduce deformation of the machine tool guideway caused by friction, significantly extend the service life of the machine tool guideway, and maintain machining accuracy.
