Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool slide rail technology, and in particular to a sealing device for a precision slide rail of a CNC machine tool. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements. It automatically processes parts according to the shape and size required by the drawings. CNC machine tools have solved the problem of processing complex, precise, small-batch, and multi-variety parts.

[0003] However, when not in use, the slide rails on existing CNC machine tools are usually exposed to the environment, which can easily lead to impurities inside the slide rails. The lack of a sealing device for the slide rails affects the equipment accuracy of the CNC machine tools and fails to meet people's needs. Therefore, a sliding rail sealing device for CNC machine tools is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a sealing device for precision slide rails of CNC machine tools.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sealing device for a precision slide rail of a CNC machine tool, comprising: The machine tool slide rail body and the machine tool slider body that is slidably connected to the machine tool slide rail body; Two right-angled cover plates are symmetrically slidably attached to the top of the machine tool slide rail body. Sealing plates are fixedly installed at both the front and rear ends of the two right-angled cover plates, and the sealing plates are slidably connected to the ends of the machine tool slide rail body through a limiting component. Two opening and closing components are used to control the synchronous movement of the two right-angled cover plates.

[0006] Preferably, the opening and closing assembly includes an electromagnet fixedly installed on the side wall of the machine tool slide rail body, a magnetic block is provided on the outer side of the electromagnet, and the magnetic block is fixedly installed on the inner side wall of the right-angle cover plate, and two springs are connected between the inner side of the right-angle cover plate and the outer side of the machine tool slide rail body.

[0007] Preferably, the limiting component includes a limiting block fixedly installed on the side of the sealing plate near the machine tool slide rail body, and the limiting block is slidably connected to the end of the machine tool slide rail body.

[0008] Preferably, two limiting ropes are connected between the inner sides of the two right-angle cover plates and the outer side of the machine tool slide rail body.

[0009] Preferably, each of the two right-angled cover plates has a bayonet on its opposite side, and the bayonet matches the machine tool slider body.

[0010] Preferably, both ends of the machine tool slide rail body are provided with limit grooves 9, and the limit grooves 9 are slidably connected with the corresponding limit blocks 8.

[0011] Compared with existing technologies, the sealing device for precision slide rails of CNC machine tools provided by this utility model has the following advantages: This invention disconnects the external power supply of the device, de-energizing the two electromagnets and preventing them from repelling the magnetic block. Then, under the action of the two springs, the two right-angled cover plates move towards each other until they are aligned, thus achieving automatic sealing of the machine tool slide rail body. This ensures that the device is not exposed to the environment when not in use, thereby ensuring the equipment accuracy of the CNC machine tool. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1 to 4 A sealing device for a precision slide rail of a CNC machine tool, comprising: The machine tool slide rail body 1 and the machine tool slider body 2 slidably connected to the machine tool slide rail body 1; two right-angle cover plates 3 are symmetrically slidably attached to the top of the machine tool slide rail body 1. Each of the two right-angle cover plates 3 has a slot 11 on its opposite side, and the slot 11 matches the machine tool slider body 2. This allows the two right-angle cover plates 3 to engage with the machine tool slider body 2 when they move towards each other to seal the machine tool slide rail body 1, so as to avoid the machine tool slider body 2 blocking the right-angle cover plate 3 and preventing the right-angle cover plate 3 from failing to seal the top of the machine tool slide rail body 1. At the same time, if the machine tool slider body 2 and the slot 11 are not aligned, the machine tool slider body 2 can be aligned with the slot 11 first.

[0016] Sealing plates 4 are fixedly installed at both ends of the two right-angled cover plates 3, and the sealing plates 4 are slidably connected to the end of the machine tool slide rail body 1 through a limiting component. The limiting component includes a limiting block 8 fixedly installed on the side of the sealing plate 4 near the machine tool slide rail body 1, and the limiting block 8 is slidably connected to the end of the machine tool slide rail body 1. Limiting grooves 9 are opened at both ends of the machine tool slide rail body 1, and the limiting grooves 9 are slidably connected to the corresponding limiting blocks 8, which plays a limiting role in the sealing plate 4 and ensures the stable movement of the right-angled cover plates 3 and the sealing plates 4.

[0017] Two opening and closing components are used to control the synchronous movement of the two right-angled cover plates 3. The opening and closing components include an electromagnet 5 fixedly installed on the side wall of the machine tool slide rail body 1. A magnetic block 6 is provided on the outside of the electromagnet 5, and the magnetic block 6 is fixedly installed on the inner side wall of the right-angled cover plate 3. Two springs 7 are connected between the inner side of the right-angled cover plate 3 and the outer side of the machine tool slide rail body 1. When the electromagnet 5 is energized, it can repel the corresponding magnetic block 6.

[0018] Furthermore, two limiting ropes 10 are connected between the inner sides of the two right-angle cover plates 3 and the outer side of the machine tool slide rail body 1, which can prevent the right-angle cover plates 3 and the sealing plate 4 from detaching from the machine tool slide rail body 1.

[0019] The working principle of this utility model is as follows: When in use, connect the external power supply of the device. At this time, the two electromagnets 5 are energized and repel the two magnetic blocks 6, so as to push the two right-angle cover plates 3 to move in opposite directions and compress the two springs 7, thereby releasing the restriction on the machine tool slider body 2 and the sealing of the machine tool slide rail body 1. When the machine tool slide rail body 1 and the machine tool slider body 2 are not in use and the machine tool slide rail body 1 needs to be sealed, first control the machine tool slider body 2 to move on the machine tool slide rail body 1 until it is aligned with the bayonet 11. Finally, disconnect the external power supply of the device, and the two electromagnets 5 are de-energized and no longer repel the magnetic block 6. Then, under the action of the two springs 8, the two right-angled cover plates 3 move towards each other until they are connected, thus achieving the sealing of the machine tool slide rail body 1.

[0020] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
