Description

Technical Field

[0001] The utility model belongs to the technical field of protection of numerical control machine tools, in particular to a top cover of a numerical control machine tool. Background Art

[0002] Machine tools are usually surrounded by machine shells to protect the processing. However, when the machine tool is processing, some existing protective equipment will cause waste chips to splash into the slide rails of the sliding door below, interfering with the smooth movement of the slide rails, thereby affecting the normal movement of the sliding door and making the protective device unable to work properly. At the same time, although some existing equipment can block the splashing of waste chips, it cannot collect the splashing waste chips. There is no special collection mechanism, and the waste chips may be scattered in the working area, increasing the difficulty and workload of cleaning. Cleaning the waste chips may become more difficult, increasing the maintenance workload and cost.

[0003] In China, the patent publication number CN 214869095 U discloses a top cover of a numerically controlled machine tool, comprising a sliding door installed on a machine tool body, an observation window being provided on the sliding door, and a cleaning device for cleaning the observation window. The cleaning device comprises a cleaning roller, and the cleaning roller is located on the inner side of the observation window, and the circumferential surface of the cleaning roller abuts against the observation window, thereby facilitating an operator to observe the processing status of a workpiece in real time and reducing the blurring of the observation window.

[0004] However, when the above device is used for machine tool processing, since the lower slide rail is open upward and is not provided with a function to prevent waste chips from entering, waste chips will enter the slide rail during processing. It is difficult to clean the waste chips that enter, which increases the maintenance workload and cost. If the waste chips are not cleaned in time, the slide rail may be blocked, resulting in the sliding door being unable to be used normally. At the same time, the sliding door of the device is a flat structure. When the machine tool is working, the waste chips will be blocked by the sliding door and accumulated on the machine tool. The accumulation of waste chips may enter the moving parts of the machine tool, such as guide rails, gears, etc., resulting in increased wear and affecting the accuracy and stability of the machine tool. At the same time, more frequent shutdowns are required to clean the waste chips, which will reduce production efficiency and increase production costs. Therefore, in order to solve the above problems, a CNC machine tool top cover is proposed. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a top cover of a numerically controlled machine tool which is highly practical, can be easily operated and has a relatively simple structure.

[0006] To solve the above technical problems, a top cover for a numerically controlled machine tool provided by the present utility model includes: support columns installed at the four corners of the machine tool main body for support, a top plate is fixed at the top of the support columns, connection mechanisms are provided on the top plate and the machine tool main body, the connection mechanisms are fixed on a protection mechanism that can block the waste chips generated during processing, and the protection mechanism is fixed on the machine tool main body through the connection mechanisms. Baffles are provided on both sides of the machine tool main body to prevent waste chips from accumulating at the connection mechanisms and causing the protection mechanism to be unable to move.

[0007] As a further solution of the present utility model, the connection mechanism includes an upper chute, a lower chute, a lower slider and an upper slider. Upper chutes are provided on the front and rear sides of the top plate, and upper sliders matching therewith are embedded in the upper chutes, and the upper sliders are of T-shaped structure, so that the protection mechanism can slide left and right flexibly on the equipment.

[0008] As a further solution of the present utility model, lower chutes are provided on the front and rear sides of the machine tool main body, and lower sliders matching therewith are embedded in the lower chutes, and the lower sliders are of F-shaped structure, which can block the accumulated waste chips and prevent them from entering the lower chutes, reducing wear.

[0009] As a further solution of the present utility model, the protection mechanism includes a visualization window, an arc-shaped sliding door and a handle. The visualization window is embedded in the arc-shaped sliding door, and the visualization window is made of a transparent material, so that the workpiece being processed can be monitored outside the arc-shaped sliding door.

[0010] As a further solution of the present utility model, two groups of the handles are fixed on the lower side of the visualization window. The arc-shaped sliding door is of a U-shaped structure, and the opening direction faces the machine tool main body, so that the lower side of the arc-shaped sliding door can collect the splashing waste chips and prevent them from all gathering on the machine tool.

[0011] As a further solution of the present utility model, upper sliders and lower sliders are respectively fixed at the top and bottom of the arc-shaped sliding door.

[0012] As a further solution of the present utility model, the baffle is of a right triangle structure, and the inclined surface side is away from the machine tool main body. The lower chute is provided below the baffle, so that the collected waste chips will preferentially gather on the side of the arc-shaped sliding door away from the machine tool main body.

[0013] Compared with the related art, a top cover for a numerically controlled machine tool provided by the present utility model has the following beneficial effects:

[0014] 1. The utility model provides a baffle and a lower slider on the machine tool body so that the waste chips generated during the processing will slide down along the sliding door and fall on the sliding door, and the F-shaped design of the lower slider blocks the accumulated waste chips so that they will not enter the lower slide groove, thereby reducing wear and extending the service life of the slide rail, and preventing larger waste chips or other foreign objects from being stuck in the slide rail, reducing the machine tool maintenance required for cleaning waste chips, and eliminating the need for frequent shutdowns to clean waste chips. Production and processing can be carried out continuously, thereby improving production efficiency.

[0015] 2. The utility model is provided with an arc-shaped sliding door, the bottom of which can collect the splashed waste chips, which has the advantage of preventing the waste chips from scattering, keeping the working area clean, reducing work interruptions caused by cleaning scattered waste chips, and improving production efficiency.

[0023] Please refer to Figure 1-5 A top cover of a CNC machine tool comprises: support columns 2 installed at the four corners of a machine tool body 1 for support, a top plate 3 is fixed on the top of the support columns 2, a connecting mechanism is provided on the top plate 3 and the machine tool body 1, the connecting mechanism is fixed on a protective mechanism 6 that can shield waste chips generated during processing, and the protective mechanism 6 is fixed to the machine tool body 1 through the connecting mechanism, and baffles 7 are provided on both sides of the machine tool body 1 to prevent waste chips from accumulating at the connecting mechanism and causing the protective mechanism 6 to be unable to move.

[0024] Preferably, the connecting mechanism includes an upper sliding groove 4, a lower sliding groove 5, a lower sliding block 8 and an upper sliding block 9. Upper sliding grooves 4 are formed on the front and rear sides of the top plate 3. The upper sliding grooves 4 are embedded with upper sliding blocks 9 that match them, and the upper sliding blocks 9 are of T-shaped structure. Lower sliding grooves 5 are formed on the front and rear sides of the machine tool main body 1. The lower sliding grooves 5 are embedded with lower sliding blocks 8 that match them, and the lower sliding blocks 8 are of F-shaped structure. The top and bottom of the arc-shaped sliding door 62 are respectively fixed with an upper sliding block 9 and a lower sliding block 8. The protection mechanism 6 is installed on the machine tool main body 1 and the top plate 3 through the upper sliding block 9 and the lower sliding block 8, so that the protection mechanism 6 can slide.

[0025] Preferably, the protection mechanism 6 includes a visualization window 61, an arc-shaped sliding door 62 and a handle 63. The visualization window 61 is embedded in the arc-shaped sliding door 62, and the visualization window 61 is made of a transparent material. Two groups of handles 63 are fixed on the lower side of the visualization window 61. The arc-shaped sliding door 62 is of a U-shaped structure, and the opening direction faces the machine tool main body 1. During use, the arc-shaped sliding door 62 is moved to a suitable position for protection through the lower handle 63, and during the machining process of the machine tool, the splashing waste chips are blocked to prevent the waste chips from scattering, keeping the working area clean. At the same time, the lower side of the arc-shaped sliding door 62 can collect the splashing waste chips, avoiding all the blocked waste chips from falling on the workbench surface, reducing the work interruption caused by cleaning the scattered waste chips, improving the production efficiency, and the working condition of the machine tool can be observed in real time through the visualization window 61 to ensure the machining accuracy of the workpiece processing.

[0026] Preferably, the baffle 7 is of a right triangle structure, and the inclined surface side is far away from the machine tool main body 1. The lower sliding groove 5 is arranged below the baffle 7. When the arc-shaped sliding door 62 can collect the splashing waste chips at the lower side, due to the setting of the bottom baffle 7 and the lower sliding block 8, the collected waste chips will preferentially gather on the side of the arc-shaped sliding door 62 far away from the machine tool main body 1, and the waste chips are gathered to the side close to the arc-shaped sliding door 62 through the lower sliding block 8, avoiding the collected waste chips from entering the lower sliding groove 5, preventing waste chips or other foreign objects from getting stuck in the slide rail, and reducing the machine tool maintenance required for cleaning the waste chips.

[0027] The working principle of a top cover of a numerical control machine tool provided by the present utility model is as follows:

[0028] Before installing the protection mechanism 6, the support columns 2 and the top plate 3 are installed on the machine tool main body 1, and it is necessary to check whether the visualization window 61 and the arc-shaped sliding door 62 are intact to ensure that there are no bad conditions.

[0029] The protection mechanism 6 is inserted into the upper sliding groove 4 and the lower sliding groove 5 of the device through the upper sliding block 9 and the lower sliding block 8, so that the protection mechanism 6 can slide on the machine tool main body 1 and the top plate 3, and a sufficient number of protection mechanisms 6 are installed according to the working range of the machine tool main body 1 to block and collect the splashing waste chips of the machine tool.

[0030] Start the machine tool, observe whether it runs smoothly, and conduct tests to ensure that the protective mechanism 6 functions normally, such as protecting the operator's safety and preventing iron chips from flying around.

[0031] When in use, the arc sliding door 62 is moved to a suitable position for protection through the handle 63 on the lower side, and during the machine tool processing, the flying waste chips are blocked to prevent the waste chips from scattering and keep the working area clean. At the same time, the lower side of the arc sliding door 62 can collect the flying waste chips. Due to the setting of the bottom baffle 7 and the lower sliding block 8, the collected waste chips will be preferentially gathered on the side of the arc sliding door 62 away from the machine tool body 1, and the waste chips will be blocked by the lower sliding block 8 to prevent the collected waste chips from entering the lower slide groove 5, thereby preventing waste chips or other foreign objects from being stuck in the slide rail.

[0032] Regularly check and maintain the protective device, wipe the visualization window 61 to avoid affecting the observation of the internal situation, and regularly clean the waste chips on the machine tool body 1 and the arc sliding door 62 to avoid accumulation, ensure that they are always in good condition, and extend the service life of the machine tool.
