[0026] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The present disclosure provides a burr removal tool for precision instruments of new energy vehicles, comprising a tool rod, a straight blade and a tool head assembly, wherein one end of the straight blade is fixedly connected to the tool rod, and the other end of the straight blade is fixedly connected to the tool head assembly, the tool rod is used to be installed on an external driving member, and the tool head assembly comprises a tool head, a tool column and a plurality of tool teeth, one end of the tool column is fixedly connected to the straight blade, and the other end of the tool column is fixedly connected to the tool head, a plurality of tool teeth are arranged at intervals between the tool head and the straight blade, each of the tool teeth is fixedly connected to the periphery of the tool column, the cross-sectional area of ​​the plurality of tool teeth gradually increases along the direction approaching the straight blade, and the cross-sectional area of ​​the tool head is less than or equal to the cross-sectional area of ​​the adjacent tool teeth.

[0030] The above-mentioned burr removal tool has a cutter head, a cutter column, a straight blade and a cutter bar connected in sequence, and a plurality of cutter teeth are arranged at intervals between the cutter head and the straight blade. When the external drive member drives the cutter bar to move, the product first contacts the cutter head, so that the cutter head preliminarily scrapes off the burr in the product hole. When the cutter bar continues to move, the product contacts the plurality of cutter teeth respectively, so that the cutter teeth further scrape off the burr in the hole. Moreover, since the cross-sectional area of ​​the plurality of cutter teeth gradually increases along the straight blade direction, the burr in the hole is better scraped off by the cutter teeth. Compared with the one-time stamping and scraping operation of the traditional tool, the present application scrapes off the burr in the product hole in steps through the cooperation of the cutter head and a plurality of cutter teeth, thereby reducing the rigid stress on the tool, avoiding damage to the tool structure, and thus extending the service life of the tool.

[0031] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0032] like Figure 1 and Figure 2 As shown, an embodiment of a burr removal tool 10 for precision instruments of new energy vehicles includes a tool rod 100, a straight blade 200 and a tool head assembly 300, one end of the straight blade 200 is fixedly connected to the tool rod 100, and the other end of the straight blade 200 is fixedly connected to the tool head assembly 300, and the tool rod 100 is used to be installed on an external driving member so that the external driving member drives the tool rod 100 to move.

[0033] Furthermore, the cutter head assembly 300 includes a cutter head 310, a cutter column 320 and a plurality of cutter teeth 330, one end of the cutter column 320 is fixedly connected to the straight blade 200, the other end of the cutter column 320 is fixedly connected to the cutter head 310, a plurality of cutter teeth 330 are arranged at intervals between the cutter head 310 and the straight blade 200, each of the cutter teeth 330 is fixedly connected to the periphery of the cutter column 320, the cross-sectional area of ​​the plurality of cutter teeth 330 gradually increases in the direction approaching the straight blade 200, and the cross-sectional area of ​​the cutter head 310 is less than or equal to the cross-sectional area of ​​adjacent cutter teeth 330.

[0034] In this embodiment, the cutter head 310 and the plurality of cutter teeth 330 are sequentially arranged on the cutter column 320 at intervals. The cross-sectional area of ​​the cutter head 310 and the plurality of cutter teeth 330 are adapted to the shape of the product hole, and the cross-sectional area of ​​the cutter head 310 is smaller than the cross-sectional area of ​​the adjacent cutter teeth 330. The cross-sectional area of ​​the cutter teeth 330 adjacent to the straight edge 200 is equal to the cross-sectional area of ​​the product hole, that is, the cross-sectional area of ​​the cutter head 310 is the smallest, and the cross-sectional areas of the plurality of cutter teeth 330 increase sequentially along the direction of the straight edge 200. When the external drive member drives the cutter bar 100 to move, the cutter head 310 first abuts against the flash edge in the product hole, so that the cutter head 310 initially scrapes off the flash edge in the hole. When the cutter bar 100 continues to move, the plurality of cutter teeth 330 respectively abut against the flash edge in the hole, so that the plurality of cutter teeth 330 further scrapes off the flash edge in the hole. When the product abuts against the straight edge 200, the external drive member stops working, and the flash edge removal operation is completed. In this way, the blade head 310 and the plurality of blade teeth 330 scrape off the burrs in the hole in steps, thereby reducing the rigid stress on the tool and avoiding damage to the tool.

[0035] In the above-mentioned burr removal tool, the cutter head 310, the cutter column 320, the straight blade 200 and the cutter bar 100 are connected in sequence, and a plurality of cutter teeth 330 are arranged at intervals between the cutter head 310 and the straight blade 200. When the external driving member drives the cutter bar 100 to move, the product first abuts against the cutter head 310, so that the cutter head 310 preliminarily scrapes off the burrs in the product hole. When the cutter bar 100 continues to move, the product abuts against the plurality of cutter teeth 330 respectively, so that the cutter teeth 330 further scrape off the burrs in the hole. Moreover, since the cross-sectional area of ​​the plurality of cutter teeth 330 gradually increases along the direction of the straight blade 200, the burrs in the hole are better scraped off by the cutter teeth 330. Compared with the conventional one-time stamping and scraping operation of the cutter, the present application scrapes off the burrs in the product hole in steps through the cooperation of the cutter head 310 and the plurality of cutter teeth 330, reduces the rigid stress on the cutter, avoids damage to the cutter structure, and thus prolongs the service life of the cutter.

[0036] In one embodiment, the cutter head 310, the cutter column 320 and the plurality of cutter teeth 330 are an integrally formed structure. It is understood that the cutter head 310, the cutter column 320 and the plurality of cutter teeth 330 are made by an integral die-casting process, so that the structural strength between the cutter head 310, the cutter column 320 and the plurality of cutter teeth 330 is higher.

[0037] like Figure 1 As shown, in one embodiment, the edge of each of the blade teeth 330 is provided with a chip dividing groove 331, and the chip dividing groove 331 is used for the flash to pass through. It can be understood that when the blade teeth 330 scrape the flash in the hole, the flash passes through the chip dividing groove 331 and is discharged.

[0038] like Figure 1 As shown, in one embodiment, the chip grooves 331 of the plurality of teeth 330 are staggered in a direction close to the straight edge 200 so that the flash in the hole can be better discharged from the plurality of chip grooves 331 .

[0039] like Figure 1 As shown, in one embodiment, the knife bar 100 is provided with a limiting groove 110, and the limiting groove 110 is used for the limiting column to pass through. It can be understood that the limiting column of the external driving member passes through the limiting groove 110 to fix the knife bar 100 to the external driving member.

[0040] In one embodiment, the thickness of the cutter head 310 is greater than the thickness of the cutter teeth 330. It is understood that the cutter head 310 first contacts the burr, that is, the force between the cutter head 310 and the burr is the greatest, and the thickness of the cutter head 310 is increased to make the structural strength of the cutter head 310 higher.

[0041] In one embodiment, the cross-sectional area of ​​the cutter head 310 is elliptical, and the cross-sectional area of ​​each of the cutter teeth 330 is elliptical. In this embodiment, the shapes of the cutter head 310 and the cutter teeth 330 are adapted to the shape of the hole. Of course, for holes of other shapes, the shapes of the cutter head 310 and the cutter teeth 330 can be adjusted accordingly, such as circular or rectangular.

[0042] In one embodiment, the thickness of the cutter head 310 is 2 mm-4 mm. In this embodiment, the thickness of the cutter head 310 is 4 mm.

[0043] In one embodiment, the distance between two adjacent blade teeth 330 is 2 mm to 3 mm. In this embodiment, the distance between two adjacent blade teeth 330 is 3 mm.

[0044] The present application also provides a burr removal device, including the burr removal tool 10 for precision instruments of new energy vehicles as described in any of the above embodiments.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] In the above-mentioned burr removal tool, the cutter head 310, the cutter column 320, the straight blade 200 and the cutter bar 100 are connected in sequence, and a plurality of cutter teeth 330 are arranged at intervals between the cutter head 310 and the straight blade 200. When the external driving member drives the cutter bar 100 to move, the product first abuts against the cutter head 310, so that the cutter head 310 preliminarily scrapes off the burrs in the product hole. When the cutter bar 100 continues to move, the product abuts against the plurality of cutter teeth 330 respectively, so that the cutter teeth 330 further scrape off the burrs in the hole. Moreover, since the cross-sectional area of ​​the plurality of cutter teeth 330 gradually increases along the direction of the straight blade 200, the burrs in the hole are better scraped off by the cutter teeth 330. Compared with the conventional one-time stamping and scraping operation of the cutter, the present application scrapes off the burrs in the product hole in steps through the cooperation of the cutter head 310 and the plurality of cutter teeth 330, reduces the rigid stress on the cutter, avoids damage to the cutter structure, and thus prolongs the service life of the cutter.

[0047] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
