Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting machine tools, in particular to an elastic scraping structure. Background Art

[0002] Some current cutting machine tools use a sliding structure. When the worktable moves, it will carry away debris such as iron chips generated in the processing area from the processing area, resulting in problems such as iron chips in the non-processing area. Therefore, a machine tool guard is required. However, the accumulation of chips on the machine tool guard will affect the movement and protection effect of the guard. Many machine tool guards use fixed scraper strips. Although this can meet the scraping needs of the machine tool guard to a certain extent, there are also some other problems, such as difficulty in installation and adjustment, the existence of gaps that do not meet the protection effect requirements, and excessive resistance to back and forth movement. To solve the above problems, an elastic scraper structure is usually used, which uses the elastic force of the elastic part to ensure that the scraper plate can always be in contact with the machine tool guard.

[0003] For example, Chinese utility model patent CN209503633U discloses a floating scraper plate protection device, in which the scraper plate is always in contact with the workbench guard under the action of a compressed elastic member, scraping chips cleanly and providing good protection. However, the elastic member is exposed to the working space of the machine tool, and the elastic member will be affected by chip splashes from the machining area of the machine tool and contaminated by the cutting fluid, which may cause the elastic member to become blocked or fail, reducing its service life and requiring frequent disassembly and cleaning.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an elastic scraping structure, which can effectively protect the scraping structure from being contaminated by cutting fluid, prevent cutting blockage, increase service life, and ensure scraping effect.

[0007] The lower end surface of the scraper plate contacts the surface of the workbench guard, and the scraper plate and the workbench guard are relatively movable.

[0008] Furthermore, the scraper guard shell includes a first guard plate, a second guard plate and a machine tool vertical guard cover. The first guard plate and the machine tool vertical guard cover are vertically arranged and spaced in parallel. The first guard plate, the machine tool vertical guard cover and the second guard plate together form the installation cavity.

[0009] Furthermore, the scraper plate is evenly provided with a plurality of limiting holes along the length direction, and a plurality of nuts are welded on the outside of the scraper protection shell along the length direction, and the limiting holes and the nuts correspond one to one; the limiting holes are long strip holes;

[0010] The nut is threadedly connected to the limiting screw, and the limiting screw passes through the nut and is inserted into the limiting hole.

[0011] Furthermore, a blind hole is provided at the top of the scraper plate, and the elastic member is installed in the blind hole. One end of the elastic member abuts against the blind hole, and the other end abuts against the bottom of the second protective plate.

[0012] Furthermore, a water storage tank is provided on the end surface of the scraper plate that contacts the workbench guard.

[0013] Furthermore, the second protective plate and the first protective plate are integrally formed into an inverted L-shaped plate; the inverted L-shaped plate is fixedly connected to the side of the vertical shield of the machine tool.

[0014] Furthermore, the second protective plate is a horizontal machine tool shield parallel to the workbench shield, and the tops of the first protective plate and the vertical machine tool shield are both welded to the bottom of the horizontal machine tool shield.

[0015] Furthermore, the scraper plate is made of polytetrafluoroethylene.

[0018] The utility model can effectively scrape away impurities such as iron filings adhering to the workbench guard, thus meeting the use requirements.

[0019] The utility model has good adjustability and can move within a certain range along the surface of the workbench shield.

[0020] The utility model provides an elastic member so that the gap between the scraping plate and the workbench shield is very small and does not generate great resistance.

[0021] The utility model has a simple structure and is easy to install.

[0028] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-2 As shown, this embodiment provides an elastic scraper structure, including a scraper protection shell 1 and a scraper plate 4, the scraper protection shell 1 is an inverted U-shaped structure, and a mounting cavity is formed inside the scraper protection shell 1; the scraper plate 4 is installed in the mounting cavity, and an elastic member 3 is arranged between the top of the scraper plate 4 and the top wall of the mounting cavity. The elastic member 3 and the scraper plate 4 are arranged in the mounting cavity of the scraper protection shell 1, which can effectively protect the scraper structure from being contaminated by the cutting fluid and prevent cutting blockage. At the same time, it can limit the movement of the scraper plate 4 and the elastic member 3, and play a certain guiding role.

[0031] The scraper plate 4 is made of polytetrafluoroethylene.

[0032] The elastic member 3 can be a spring.

[0033] There are multiple elastic members 3 , and the multiple elastic members 3 are evenly arranged along the length direction of the cutting plate 4 .

[0034] The lower end surface of the scraper plate 4 contacts the surface of the workbench guard 2, and the scraper plate 4 and the workbench guard 2 can move relatively to scrape off impurities such as iron filings adhering to the workbench guard.

[0035] A blind hole 5 is provided on the top wall of the scraper protection shell 1 or the top end of the scraper plate 4 , and the elastic member 3 is installed in the blind hole 5 .

[0036] The scraper plate 4 is evenly provided with a plurality of limiting holes 7 along the length direction (the arrows in the figure indicate the length direction of the scraper plate), and a plurality of nuts 6 are welded along the length direction on the outside of the scraper protective shell 1, and the limiting holes 7 and the nuts 6 correspond one to one; the limiting holes 7 are long strip holes; the nuts 6 are threadedly connected with the limiting screws 8, and the limiting screws 8 pass through the nuts 6 and are inserted into the limiting holes 7. The limiting screws 8 and the limiting holes 7 limit the up and down floating range of the scraper plate 4, thereby ensuring the flexibility of the scraper plate 4 to move back and forth.

[0037] A water storage tank 9 is provided on the end surface of the scraper plate 4 that contacts the workbench shield 2, which can achieve a certain lubrication effect.

[0038] The scraper protection shell 1 includes a first protection plate 101, a second protection plate 103 and a machine tool vertical protection cover 102. The first protection plate 101 and the machine tool vertical protection cover 102 are vertically arranged and parallel to each other; the first protection plate 101, the machine tool vertical protection cover 102 and the second protection plate 103 together form the installation cavity.

[0039] One end of the elastic member 3 abuts against the blind hole 5 , and the other end abuts against the bottom of the second protective plate 103 .

[0040] In this embodiment, the second protective plate 103 and the first protective plate 101 are integrally formed into an inverted L-shaped plate, and the inverted L-shaped plate is fixedly connected to the side of the machine tool vertical shield 102 to form the installation cavity.

[0041] Moreover, the vertical machine tool shield 102 and the horizontal workbench shield 2 can move relative to each other. Specifically, the vertical machine tool shield 102 moves horizontally on the workbench shield 2, or the workbench shield 2 itself moves horizontally, and the vertical machine tool shield and the workbench shield 2 are not connected.

[0042] Example 2

[0044] The horizontal guard of the machine tool can drive the first protective plate 101, the vertical guard of the machine tool 102 and the scraper plate 4 to move forward and backward together.

[0045] The utility model is provided with a scraper protection shell, which provides an installation position for the scraper plate and the elastic part and can limit the movement of the scraper plate and the elastic part, thereby playing a certain guiding role; the scraper protection shell can protect the parts from being corroded by external cutting fluids to a great extent, thereby improving the service life.

[0046] The scraper shield of this utility model also provides a support point for the elastic member, ensuring contact between the scraper plate and the workbench shield, thereby greatly removing impurities such as iron filings from the workbench shield. Furthermore, the limiting holes in the scraper plate are elongated, providing ample adjustment space for installation and guiding the elastic movement of the elastic member, ensuring smooth movement of the structure.

[0047] The scraper plate of the utility model is made of polytetrafluoroethylene, which has good wear resistance and generates less resistance, which also greatly reduces wear and increases the service life of the parts.
