Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, specifically a protective cover for a milling and turning composite machine tool. Background Technology

[0002] The special protective cover for milling and turning machines is a protective device used on milling and turning machines. Its function is to block cutting chips and coolant generated during the machining process, prevent dust and other impurities from entering the precision parts inside the machine tool, and protect the safety of operators. This cover is widely used to protect moving parts such as guideways, spindles, and tool turrets of milling and turning machines, and is applicable to fields such as machining, aerospace, automobile manufacturing, and mold making.

[0003] However, it still has some drawbacks. For example, the current special protective covers for milling and turning machines mostly use a combination of ordinary screws and flat washers for locking structure during use. Under high-frequency vibration, they are prone to loosening, resulting in insufficient connection stability. In addition, ordinary washers have limited resistance to cutting fluid and oil corrosion, making it difficult to ensure long-term reliable protection of the protective cover under complex working conditions. This increases the frequency of inspections and maintenance costs due to loosening.

[0004] To address the aforementioned issues, this application proposes a special protective cover for milling and turning composite machine tools. Summary of the Invention

[0005] The purpose of this utility model is to provide a special protective cover for turning and milling composite machine tools, so as to solve the problem of insufficient connection stability of machine tool special protective covers mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a special protective cover for a turning and milling composite machine tool, including a fixing plate, wherein a wedge-type locking structure is fixedly connected to the front end of the fixing plate, and the number of the wedge-type locking structures is three sets.

[0007] Preferably, the front end of the fixing plate is fixedly connected to an armor protective cover, and the number of the armor protective cover is six sets.

[0008] Preferably, a pull plate is fixedly connected to the front end of the armor protective cover.

[0009] Preferably, a lower washer is fixedly connected to the outer surface of the front end of the fixing plate, and an upper washer is fixedly connected to the outer surface of the front end of the lower washer.

[0010] Preferably, a screw is fixedly connected to the outer surface of the front end of the upper washer, the screw passes through the lower washer and the upper washer, and the screw is fixedly connected to the fixing plate through the lower washer and the upper washer. The wedge-type locking structure includes a screw, a lower washer and an upper washer.

[0011] Preferably, the lower washer includes a wedge block and a ring body, with the wedge block fixedly connected to the upper outer surface of the ring body. The upper washer includes a wedge block and a ring body, with the wedge block fixedly connected to the lower outer surface of the ring body. The number of wedge blocks is multiple.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model utilizes a wedge-type locking structure, taking advantage of its unique wedge-shaped tooth meshing principle. When the machine tool vibrates during operation, multiple sets of wedge blocks precisely fit together and tightly interlock to form a stable mechanical meshing structure. The wedge angle difference cleverly counteracts the tendency of the nut to loosen, continuously and stably providing a reverse locking force to firmly lock the connection parts, thus strengthening the connection stability from a structural perspective. At the same time, its tooth shape design is specially adapted to the machine tool processing environment, effectively resisting long-term corrosion from cutting fluid and oil, avoiding structural failure caused by corrosion, ensuring that the protective cover maintains a reliable protective state during long-term use, improving the locking and protective performance of the protective cover of turning and milling composite machine tools under complex working conditions such as multiple alternating processes, high-frequency vibration, and oil splashes, reducing problems such as protective cover displacement and protective failure caused by loose connections, reducing the frequency of equipment downtime for maintenance, and saving the manpower and time costs required for maintenance.

[0015] 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.

[0016] Please see Figures 1-4A special protective cover for milling and turning machines includes a fixed plate 1. A wedge-type locking structure 2 is fixedly connected to the front end of the fixed plate 1. There are three sets of wedge-type locking structures 2. Through the unique wedge-shaped tooth meshing principle, when the machine tool vibrates during operation, multiple sets of wedge-shaped blocks 8 precisely fit together and tightly interlock to form a stable mechanical meshing structure. The wedge angle difference cleverly counteracts the tendency of the nut to loosen, continuously and stably providing a reverse locking force to firmly lock the connection parts, thus strengthening the connection stability from a structural perspective. At the same time, its tooth shape design is specifically adapted to the machine tool processing environment, effectively resisting long-term corrosion from cutting fluid and oil, avoiding structural failure due to corrosion, ensuring the protective cover maintains a reliable protective state during long-term use, improving the locking and protective performance of the milling and turning machine tool protective cover under complex working conditions such as alternating processes, high-frequency vibration, and oil splashing, reducing problems such as cover displacement and protective failure caused by loose connections, reducing the frequency of equipment downtime for maintenance, and saving the manpower and time costs required for maintenance.

[0017] In this embodiment, as shown Figures 1-2 As shown, the front end of the fixed plate 1 is fixedly connected to armored protective cover plates 3, and there are six sets of armored protective cover plates 3. The front end of the armored protective cover plates 3 is fixedly connected to a pull plate 4. The fixed plate 1 serves as the installation base and load-bearing component of the entire protective cover. The six sets of armored protective cover plates 3 fixedly connected to its front end cooperate with each other to form a protective barrier for the key moving parts of the machine tool. It can effectively block cutting chips, coolant and dust generated during the processing. The pull plate 4 is fixedly connected to the armored protective cover plates 3 and is used to assist the multiple sets of armored protective cover plates 3 in achieving synchronous extension and linkage when the machine tool moves, ensuring the continuity of protection.

[0018] In this embodiment, as shown Figures 3-4As shown, a lower washer 6 is fixedly connected to the outer surface of the front end of the fixing plate 1. An upper washer 7 is fixedly connected to the outer surface of the front end of the lower washer 6. A screw 5 is fixedly connected to the outer surface of the front end of the upper washer 7. The screw 5 passes through the lower washer 6 and the upper washer 7, and is fixedly connected to the fixing plate 1 through the lower washer 6 and the upper washer 7. The wedge-type locking structure 2 includes the screw 5, the lower washer 6, and the upper washer 7. The lower washer 6 includes a wedge block 8 and a ring body 9. The upper outer surface of the ring body 9 is fixedly connected to the wedge block 8. The upper washer 7 includes a wedge block 8 and a ring body 9. The lower outer surface of the ring body 9 is fixedly connected to the wedge block 8. There are multiple sets of wedge blocks 8. The three sets of wedge-type locking structures 2 set at the front end of the fixing plate 1 play a core locking role. The screw 5 passes through the lower washer 6 and the upper washer 7 in sequence and is fixedly connected to the fixing plate 1. The wedge block 8 and the upper washer 7 are fixed at the upper end of the ring body 9 of the lower washer 6. The wedge blocks 8 fixed at the lower end of the ring body 9 engage precisely with each other. When the machine tool generates high-frequency vibration, multiple sets of wedge blocks 8 generate a reverse force by means of the wedge angle difference, which counteracts the loosening tendency of the screw 5 and continuously provides a stable locking force, ensuring that the components of the protective cover are firmly connected, thereby achieving a long-term reliable protective effect under complex working conditions.

[0019] Working Principle: A special protective cover for milling and turning composite machine tools. A fixed plate 1 serves as the mounting base and load-bearing component of the entire cover. Six sets of armor-like protective plates 3 are fixedly connected to its front end, cooperating to form a protective barrier for the machine tool's critical moving parts. A pull plate 4 is fixedly connected to the armor-like protective plates 3, assisting in the synchronous extension and retraction of the multiple sets of armor-like protective plates 3 during machine tool movement, ensuring continuous protection. Three sets of wedge-type locking structures 2 at the front end of the fixed plate 1 play a core locking role. Screws 5 pass through the lower washer 6 and the upper washer 7 sequentially before being fixedly connected to the fixed plate 1. The wedge-shaped blocks 8 fixed at the upper end of the lower washer 6's ring body 9 and the wedge-shaped blocks 8 fixed at the lower end of the upper washer 7's ring body 9 precisely mesh with each other. When the machine tool generates high-frequency vibrations during operation, the multiple sets of wedge-shaped blocks 8 generate a reverse force through the wedge angle difference, offsetting the force of screws 5. It resists the loosening trend and continuously provides stable locking force to ensure that all parts of the protective cover are firmly connected, thereby achieving a long-term reliable protective effect under complex working conditions. At the same time, its toothed design is specially adapted to the machine tool processing environment, which can effectively resist the long-term corrosion of cutting fluid and oil, avoid structural failure caused by corrosion, ensure that the protective cover maintains a reliable protective state during long-term use, and improve the locking and protective performance of the milling and turning machine tool protective cover under complex working conditions such as multiple processes, high-frequency vibration, and oil splash.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
