Description

Technical Field

[0001] The utility model relates to a protective cover structure for a tool magazine of a machine tool. Background Art

[0002] When a machine tool is designed and used, a tool magazine cover is installed on the tool magazine of the machine tool to prevent fine chips generated during machine tool processing from entering the tool magazine and causing the tool magazine to malfunction.

[0003] Therefore, a complete set of machine tools needs to be equipped with a suitable tool magazine protective cover to meet the usage requirements of the machine tool.

[0004] Currently, the protective cover structure of the tool magazine designed by machine tool manufacturers on the market is as shown in the attached Figure 1 figure. The reference numerals are as follows: 1. protective cover side plate; 2. tool magazine; 3. bottom brush; 4. protective cover bottom plate; 5. side end brush; 6. tool; 7. tool magazine tool changer arm.

[0005] The protective cover includes a bottom plate and a side plate. The protective cover bottom plate is inclined and installed outside the tool magazine and fixedly connected to the tool magazine. The protective cover side plate is fixedly connected to the protective cover bottom plate, and a tool change notch is provided between the two. The bottom brush and the side end brush are both installed on the protective cover side plate and the protective cover bottom plate. During the tool change process of the machine tool, the brush can brush the surface of the tool passing through the tool change notch multiple times to remove the chips on the surface of the tool. At the same time, the chips brushed off will not enter the tool magazine protective cover, which can ensure the stability of the tool during the processing process, extend the service life of the tool magazine, and reduce the failure rate of the tool magazine.

[0006] During the actual use and processing of the machine tool, there will be the following situations:

[0007] 1. The fine chips generated during machine tool processing will adhere to the brush. The fine chips adhering to the brush are not easy to clean and will not fall off by themselves. During the tool change process of the tool magazine, these adhering chips are likely to enter the tool taper shank mounting surface, affecting the tool mounting accuracy and thus the machining effect of the machine tool.

[0008] 2. By installing a brush to brush the surface of the tool multiple times, during the tool change process of the tool magazine, part of the hair on the brush will be cut off during the brushing process on the surface of the sharp tool. After using for a period of time, the brush will become sparse and can no longer play the role of brushing the surface of the tool and blocking chips. At the same time, the hair cut off from the brush is also likely to enter the tool magazine, causing the tool magazine to malfunction.

[0009] Therefore, during the operation and use of machine tools, manufacturers often manually replace and install new brushes frequently. The purchase cost of machine tool brushes is relatively high, increasing the use cost of machine tools. At the same time, the installation of brushes also requires professional personnel, otherwise it is easy to cause potential safety hazards. In addition, in the current social background of the large-scale development of automated production lines, the manufacturing production lines in most intelligent workshops are basically unmanned automatic modes, which cannot meet the requirements of replacing brushes.

[0027] Please refer to Figures 2 - 7 , the embodiments of the present utility model include:

[0028] A machine tool tool magazine protective cover structure, including a tool magazine protective cover 3 arranged outside the tool magazine 1 and fixed on the machine tool sheet metal 2, a front bottom plate 4 of the tool magazine protective cover, a moving door assembly, and a rear bottom plate 5 of the tool magazine protective cover.

[0029] Among them, the tool magazine protective cover 3 covers the upper part of the tool magazine 1, and the front bottom plate 4 and the rear bottom plate 5 of the tool magazine protective cover are distributed at intervals before and after and are located on both sides of the tool change port at the bottom of the tool magazine 1 to provide comprehensive protection for the tool magazine 1.

[0030] A transparent viewing window plate 6 is provided on the side of the tool magazine protective cover 3, which can facilitate viewing the internal situation of the tool magazine protective cover 3.

[0031] The moving door assembly includes a linear guide 7, a slider 8, a moving door plate 9 of the tool magazine protective cover, and a cylinder 10.

[0032] Two linear guides 7 are provided and are fixedly arranged in parallel at both ends of the front bottom plate 4 and the rear bottom plate 5 of the tool magazine protective cover to provide moving guidance.

[0033] Both ends of the moving door plate 9 of the tool magazine protective cover are respectively slidably arranged on the linear guide 7 through sliders 8. Two sliders 8 are arranged on any one of the linear guides 7 and are connected to the moving door plate 9 of the tool magazine protective cover to ensure the connection stability.

[0034] A bellows protective cover 11 is arranged on any one of the linear guides 7. One end of the bellows protective cover 11 is fixed on the front bottom plate 4 of the tool magazine protective cover, and the other end is fixed on the moving door plate 9 of the tool magazine protective cover. As the moving door plate 9 of the tool magazine protective cover moves back and forth, the bellows protective cover 11 will be stretched and compressed correspondingly.

[0035] The bellows protective cover 11 is provided with an installation groove 12 with a C-shaped structure on the side where the linear guide 7 is installed. V-shaped clamping edges 13 protrude from two opposite sides of the installation groove 12. A V-shaped positioning groove 14 is arranged on the linear guide 7 to correspond to the clamping edges 13 for positioning, ensuring the use stability of the bellows protective cover 11 during the moving process.

[0036] The cylinder 10 is fixed to the top of the rear bottom plate 5 of the tool magazine protective cover parallel to the linear guide 7. The driving end of the cylinder 10 is connected to the top of the moving door plate 9 of the tool magazine protective cover through a support rod 15, and the moving door plate 9 of the tool magazine protective cover is driven to move back and forth by the cylinder 10. In addition, in-place signal sensors are provided at both ends of the cylinder 10. Whether the moving door plate 9 of the tool magazine protective cover is opened is detected through the induction signal, and thus it can be judged whether the tool change operation is performed.

[0037] Working principle: By designing the moving door plate 9 of the tool magazine protective cover that can be opened or closed back and forth, the air intake is controlled to make the cylinder 10 extend and contract to drive the back-and-forth movement of the moving door plate 9 of the tool magazine protective cover. When the tool magazine 1 needs to change tools, the support rod 15 on the cylinder 10 is controlled to extend, and the moving door plate 9 of the tool magazine protective cover moves forward to open, and at this time, the tool change operation of the tool magazine 1 can be performed. After the tool change of the tool magazine 1 is completed, the support rod 15 on the cylinder 10 is controlled to contract, and the moving door plate 9 of the tool magazine protective cover is closed.

[0038] Tool change principle of the tool magazine tool change arm 16: When the moving door plate 9 of the tool magazine protective cover moves forward to open and the tool magazine 1 performs the tool change operation of the tool magazine 1, the tool magazine tool change arm 16 rotates clockwise by 90°, and the tool magazine tool change arm 16 clamps the tool (viewed from the bottom up). At this time, the direction of the tool magazine tool change arm 16 is consistent with the surface direction of the front plate of the tool magazine protective cover 3, as Figure 2 in the figure. After that, the tool magazine tool change arm 16 descends a certain height, and continues to rotate clockwise by 180° during the descent (viewed from the bottom up). At this time, the tool can be installed on the machine tool spindle. After the tool is installed, the tool magazine tool change arm 16 rotates counterclockwise by 90° to return to the original position, as Figure 3 in the figure. At this time, the entire tool change operation is completed.

[0039] In summary, a tool magazine protective cover structure of a machine tool pointed out by the present utility model adds a moving door assembly under the tool magazine protective cover of the machine tool, so that the tool magazine can be in a closed space when the tool change operation is not performed, and the fine chips generated during processing cannot enter; for machine tool manufacturers: this tool magazine protective cover structure of the machine tool can meet the protection requirements of the tool magazine for machine tools on more and more future automated intelligent integrated unmanned production lines, achieving the purpose of extending the service life of the tool magazine and reducing the failure rate of the tool magazine; for machine tool users: this tool magazine protective cover structure of the machine tool can be selectively added according to the actual processing requirements of the machine tool use, avoiding the drawback of the common tool magazine protective cover on the market that needs to frequently replace the brush.
