Description

Scraper with hidden dust cover

This creation relates to the field of mechanical dust protection, especially a scraper with a concealed dust protection cover, so that chips and rust will not be caught between the covers, increasing the smoothness of the use of the cover and protecting the flatness of the guide rail of the machine tool.

In order to prevent cutting chips from falling into the sliding part of the machine and affecting the precision of the operation, various power tools are equipped with a dust-proof cover with a telescopic effect to block the cutting chips. Each cover of the dust-proof cover is provided with a scraping device. 切削 During the expansion and contraction of the dust-proof cover, the chips falling on the cover are scraped and removed from the cover.

As shown in the new patent No. M328917 of the Republic of China, most dust protection covers have a cover, a plate is located below the front end of the cover, and a scraping unit is arranged in the plate, and the cover and the plate pass through Spot welding or high frequency combined to remove chips from the cover.

However, the disadvantage of this design is that there will be a gap at the joint between the cover and the plate, and it is easy for chips and rust to get stuck in the gap. Over time, it will cause the cover to spread unsteadily and affect the precision of processing.

Therefore, the above problems need to be improved. After many years of experience and research, the creator of this case finally developed a scraper with a hidden dust-proof cover in this case.

The main purpose of this creation is to improve the shortcomings of the conventional structure, to prevent chips and rust from getting stuck at the joint between the cover and the scraper module, to keep the cover unfolding smoothly, and to prevent chips and rust from falling on the guide rail to maintain machinery Precision.

The structure that can achieve the above purpose includes at least two layers of cover bodies and two or more sets of scraper modules. The cover body includes a flat portion and an inclined sliding portion. The sliding part is arranged at the front end of the flat part, and a mounting part is provided below the cover body at the joint between the flat part and the guide part; the scraping module includes a fixing unit and a scraping unit, and the fixing The unit is mounted on the mounting portion, and the fixed unit is a flat plate, and is bent inward on both sides of the fixed unit to form a clamping end; the scraping unit is made of soft plastic, and is mounted on the The bottom end of the fixing unit and the scraping unit is provided with a scraping end, which corresponds to the flat portion of the cover body of the next layer, and scrapes the chips falling on the flat portion.

In this way, through this creation, the cutting chips of the machine during processing are recovered by the guide slide tribe's chip curling device in the machine. Since the joint between the cover body and the scraper module is hidden inside the slide guide, it will not The situation that the conventional chips and rust are stuck at the joint, and the plane part of the cover body and the guide sliding part are designed together can reduce the volume of the cover.

In order to allow your reviewers to further understand and agree with the features and characteristics of this case, the following preferred embodiments are listed and illustrated in conjunction with the drawings as follows: Please refer to Figures 1 to 5. The scraper mainly includes: a cover body 1 including at least two layers and a scraper module 2 of two or more layers.

As shown in FIGS. 1 to 5, the cover body 1 includes a flat portion 11 and an inclined sliding guide portion 12. The guide sliding portion 12 is disposed at the front end of the flat portion 11. A mounting portion 13 is provided below the junction of the flat surface portion 11 and the guide sliding portion 12; the aforementioned guide sliding portion 12 can be punched through a punching machine, a folding machine, or the like to form an inclined guide sliding portion 12, which Chips, cutting fluid, and other materials are smoothly slid into the chip curling device (not shown) of the machine tool; further, the thickness of the cover body 1 is preferably 1.5 mm or more.

As shown in FIGS. 1 to 5, the scraping module 2 includes a fixing unit 21 and a scraping unit 22. The fixing unit 21 is mounted on the mounting portion 13, and the fixing unit 21 is a flat plate. The two sides of the fixing unit 21 are bent inward to form a clamping end 211. The scraping unit 22 is made of soft plastic, which is installed in the fixing unit 21, and the scraping unit 22 receives the clamping end. 211 is clamped and fixed, and a scraping end 221 is provided at the bottom end of the scraping unit 22, which corresponds to the flat portion 11 of the cover body 1 in the next layer, and scrapes off chips and cuttings falling on the flat portion 11. Further, as shown in FIGS. 1 to 6, a cutout 222 is provided on the top of the scraping unit 22, This makes it easier to assemble the scraping unit 22 to the fixing unit 21.

The fixing unit 21 of the scraper module 2 is fixed to the mounting portion 13 through methods such as spot welding and high frequency welding. The scraper unit 22 is made of a material such as PU (polyurethane for short) and has Water resistance and good flexibility can scrape off chips and cutting fluid from the flat portion 11, thereby maintaining the cleanness of the cover body 1 and increasing the service life.

Please refer to Figures 4 and 5. According to the above description, when the machine is processing, chips, cutting fluid, rust and other materials can be excluded through the guide sliding portion 12 when the cover body 1 falls; when the machine moves regardless of When the cover body 1 is unfolded or retracted, the scraper module 2 removes chips and cutting fluid on the surface of the flat portion 11 through the scraper end 221, so that the cover body 1 is kept clean, and then the cover body 1 The movement is smooth; and the design of this creation hides the scraper module 2 inside the cover body 1 so that chips and rust will not remain, making the machine work better and smoothly to prevent chips from falling on the guide rail.

Please refer to FIG. 6. In actual application, the cover body 1 presents a plate-shaped plate structure. The mounting portion 13 on the inner side of the flat portion 11 of the cover body 1 and the inner sides of the adjacent sides 14 on both sides of the flat portion are both inside. Mounting portions 13 are provided, and these mounting portions 13 are provided for installing the scraping module 2, whereby the cuttings on the surface of the flat body 11 and the vertical adjacent side 14 of the cover body 1 can be removed through the scraping module 2. Cutting fluid and other materials to maintain the overall cleanliness.

In addition, another feature of this creation is that the scraping devices of the conventional dust cover are overlapped under the cover, so the installation will have problems of tilt and large volume. However, the scraping module 2 of this creation is Hidden under the cover body 1, the volume of the mechanism can be reduced and the overall accuracy can be improved. Therefore, for example, a desktop machine tool is also suitable for using the structure of this creation to improve accuracy.

In summary, this creative structure has never been seen in books or publicly used, and is in line with the requirements for new patent applications. We urge the Bureau to make a clear reference and grant the patent as soon as possible.

For those who need to know, the above are the technical principles that are immediately applied to the specific implementation of this creation. If the changes made according to the concept of this creation have not exceeded the spirit covered by the description and drawings, All should be shared with Chen Ming within the scope of this creation.
