Description

Technical Field

[0001] This application relates to the technical field of cutting tools, and in particular to a plate chamfering tool. Background Technology

[0002] Chamfering tools are an important component of machining tools. Currently, with the development of the machinery industry, users have placed higher demands on product machining quality, reliability, and efficiency. There is a pursuit of standardized machining, ensuring that cutting angles and dimensions meet uniform standards.

[0003] In sheet metal processing, chamfering is a common procedure. Sheets typically have four corners, which need to be cut. Chamfering removes burrs from the edges of metal sheets produced during machining and facilitates assembly. However, existing chamfering equipment can only chamfer each corner sequentially. After chamfering one corner, the sheet needs to be rotated to align the uncut corner with the chamfering equipment, a cumbersome process that affects efficiency and needs improvement. Utility Model Content

[0004] The purpose of this application is to provide a sheet metal chamfering tool to improve the efficiency of chamfering sheet metal.

[0005] The present application provides a plate chamfering tool with the following technical solution: it includes a positioning end cover, the positioning end cover is rotatably connected to a tool bar, the tool bar can rotate around its own axis, the tool bar is provided with a first tool disc and a second tool disc at intervals, and a blade is connected to one side of the first tool disc and the second tool disc facing each other, each blade is provided with a chamfering groove, and a chamfered area is formed between the blade on the first tool disc and the blade on the second tool disc.

[0006] By adopting the above technical solution, the sheet metal is placed in the chamfering area, with both ends of the sheet metal abutting against the inner walls of the two chamfering grooves. The cutter bar rotates around its own axis, meaning the first cutter head, the second cutter head, and all the blades rotate around the axis of the cutter bar. This allows the blades on the first cutter head and the cutter heads on the second cutter head to simultaneously chamfer both ends of the sheet metal, improving the efficiency of chamfering. After both ends of the sheet metal have been chamfered, the sheet metal is moved so that the un-chamfered ends abut against the inner walls of the chamfering grooves, reducing the number of times the sheet metal needs to be moved and improving the overall efficiency of chamfering the sheet metal.

[0007] Optionally, each of the blades is connected to a locking element, and the blade is connected to the first cutter head or the second cutter head via the locking element.

[0008] By adopting the above technical solution, when the blade is damaged, it can be removed from the first or second cutter head through the locking device, making it convenient to replace the blade.

[0009] Optionally, both the first cutter head and the second cutter head are provided with positioning grooves, which are used to cooperate with the blades.

[0010] By adopting the above technical solution, the blade is inserted into the positioning groove, and the outer surface of the blade fits against the inner wall of the positioning groove. The inner wall of the positioning groove plays a positioning role in the installation of the blade, thereby improving the efficiency of installing the blade on the first or second cutting disc.

[0011] Optionally, a plurality of the chamfered grooves are provided on the blade.

[0012] By adopting the above technical solution, the blade does not need to be installed in a specific area so that the plate can be located in the chamfer groove, thus improving the efficiency of blade installation.

[0013] Optionally, the second cutter head is detachably connected to the cutter bar, and the cutter bar is connected to an adjustment component for adjusting the distance between the second cutter head and the first cutter head.

[0014] By adopting the above technical solution, the distance between the second cutter head and the first cutter head can be adjusted by adjusting the component, thereby making it suitable for plates of different sizes and improving the adaptability of the cutter.

[0015] Optionally, the second cutter head is provided with a through hole, and the cutter bar is used to slide and engage with the through hole. The adjusting assembly includes a fixing block threadedly connected to the cutter bar and a plurality of shims sleeved on the cutter bar. The second cutter head is located between the first cutter head and the fixing block, at least one of the shims is located between the first cutter head and the second cutter head, and the remaining shims are located between the second cutter head and the fixing block.

[0016] By adopting the above technical solution, the second cutter head can be removed from the cutter bar by loosening the fixing block. Depending on the actual needs, different numbers of shims can be fitted or removed from the cutter bar. Then, the second cutter head can be put back onto the cutter bar and the fixing block can be threaded onto the cutter bar to adjust the distance between the second cutter head and the first cutter head, which is quite convenient.

[0017] Optionally, the cutter head is provided with a limit block, and the second cutter head is provided with a limit groove, the limit groove being used to cooperate with the limit block.

[0018] By adopting the above technical solution, when the second cutter head is installed on the cutter bar, the limiting block is engaged in the limiting groove, and the limiting block is in contact with the inner wall of the limiting groove. The limiting block restricts the rotation of the second cutter head, thereby improving the stability of the second cutter head installed on the cutter bar.

[0019] Optionally, the positioning end cover is connected to a bearing, the positioning end cover is fixedly connected to the outer ring of the bearing, and the tool holder is fixedly connected to the inner ring of the bearing.

[0020] By adopting the above technical solution, the bearing reduces the rotational friction between the tool holder and the positioning end cover, thereby improving the rotational effect of the tool holder.

[0021] Optionally, the positioning end cover is provided with a mounting groove, which mates with the bearing. The positioning end cover is connected to a cover plate, which is connected to the positioning end cover by a fastener. The cover plate is used to cover the mounting groove and abut against the outer ring of the bearing.

[0022] By adopting the above technical solution, the bearing is installed in the mounting groove. The inner wall of the mounting groove restricts the movement of the bearing, and the cover plate restricts the bearing from leaving the mounting groove, thereby improving the stability of the bearing installed on the positioning end cover.

[0023] Optionally, the tool holder is fitted with a bottom cover, the bottom cover is provided with an abutment portion, the abutment portion abuts against the inner ring of the bearing, the tool holder is threadedly connected with a locking block, the locking block abuts against the bottom cover, the bottom cover is located between the locking block and the bearing, the bottom cover is provided with an annular block, the positioning end cover is provided with an annular groove, and the annular block is used to rotate with the annular groove.

[0024] By adopting the above technical solution, the inner wall of the annular groove restricts the movement of the annular block, that is, restricts the movement of the bottom cover, thereby improving the stability of the rotation of the tool holder at the bottom cover and locking block.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The blades on the first cutter head and the cutter heads on the second cutter head simultaneously chamfer both ends of the sheet metal, improving the efficiency of chamfering. After both ends of the sheet metal are chamfered, the sheet metal is moved so that the un-chamfered ends abut against the inner wall of the chamfering groove, reducing the number of times the sheet metal is moved and improving the overall efficiency of chamfering the sheet metal.

[0027] 2. When the second cutter head is installed on the cutter bar, the limiting block is engaged in the limiting groove. The limiting block fits against the inner wall of the limiting groove, and the limiting block restricts the rotation of the second cutter head, thereby improving the stability of the second cutter head installed on the cutter bar.

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses a plate chamfering tool.

[0036] like Figure 1 As shown, the device includes a positioning end cap 1 and a tool holder 2 rotatably connected to the positioning end cap 1. A milling machine clamps the thin end of the tool holder 2, and starting the milling machine causes the tool holder 2 to rotate at high speed around its own axis. A first cutter disc 21 is provided on the outer circumferential surface of the tool holder 2, and the first cutter disc 21 is fixedly connected to the tool holder 2. A second cutter disc 22 is detachably connected to the outer circumferential surface of the tool holder 2, and the first cutter disc 21 and the second cutter disc 22 are spaced apart. Several cutting blades 3 are detachably connected to the opposite side of the first cutter disc 21 and the second cutter disc 22. A chamfered area 23 is formed between the cutter disc on the first cutter disc 21 and the cutting blades 3 on the second cutter disc 22. Taking this embodiment as an example, each of the first cutter head 21 and the second cutter head 22 has three blades 3, which are evenly distributed around the axis of the cutter bar 2. Both the first cutter head 21 and the second cutter head 22 have several positioning grooves 211, with each blade 3 corresponding to one of the positioning grooves 211. Each blade 3 is connected to a locking element 31, which is a bolt. Each blade 3 is connected to the first cutter head 21 or the second cutter head 22 via the locking element 31. Each blade 3 has several chamfered grooves 32. In this embodiment, for example, there are four chamfered grooves 32, which are evenly distributed around the axis of the blade 3.

[0037] Combination Figure 1 , Figure 2 and Figure 3As shown, the second cutter head 22 has a through hole, and the cutter bar 2 slides into the through hole. The cutter bar 2 is connected to an adjustment component 4, which is used to adjust the distance between the second cutter head 22 and the first cutter head 21. The adjustment component 4 includes a fixing block 41 threaded onto the cutter bar 2 and several shims 42 sleeved on the cutter bar 2. The second cutter head 22 is located between the first cutter head 21 and the fixing block 41. At least one shim 42 is located between the first cutter head 21 and the second cutter head 22, and the remaining shims 42 are located between the second cutter head 22 and the fixing block 41. Taking this embodiment as an example, there are six shims 42, one shim 42 is located between the second cutter head 22 and the first cutter head 21, and five shims 42 are located between the fixing block 41 and the second cutter head 22. A limiting block 25 is fixedly connected to the outer circumference of the tool holder 2. The second cutter disc 22 and all the washers 42 have limiting grooves 221. The limiting block 25 engages with the limiting grooves 221 to prevent the second cutter disc 22 and all the washers 42 from rotating when the tool holder 2 rotates. When it is necessary to adjust the distance between the second cutter disc 22 and the first cutter disc 21, firstly, rotate the fixing block 41 to remove it from the tool holder 2; secondly, remove the five washers 42 between the fixing block 41 and the second cutter disc 22; thirdly, remove the second cutter disc 22 from the tool holder 2; then, according to actual needs, fit the required washers 42 onto the tool holder 2; finally, install the second cutter disc 22, the remaining washers 42, and the fixing block 41 sequentially on the tool holder 2, thereby completing the adjustment of the distance between the second cutter disc 22 and the first cutter disc 21.

[0038] Combination Figure 4 and Figure 5 As shown, the positioning end cover 1 is connected to a bearing 5. The positioning end cover 1 has a mounting groove 11, and the bearing 5 is installed in the mounting groove 11. The outer ring of the bearing 5 is fixedly connected to the inner wall of the mounting groove 11, and the inner ring of the bearing 5 is fixedly connected to the outer circumferential surface of the tool holder 2. The positioning end cover 1 is detachably connected to a cover plate 6. The cover plate 6 is connected to the positioning end cover 1 by several fasteners, namely bolts. When the cover plate 6 is installed on the positioning end cover 1, the cover plate 6 covers the mounting groove 11 and abuts against the outer ring of the bearing 5, thereby preventing the bearing 5 from disengaging from the mounting groove 11.

[0039] Combination Figure 4 and Figure 5 As shown, the tool holder 2 is fitted with a bottom cover 7. The bearing 5 is located between the bottom cover 7 and the first tool disc 21. The bottom cover 7 has an abutment part 71 and a ring block 72 on the side near the bearing 5. Both the abutment part 71 and the ring block 72 are integrally formed with the bottom cover 7. The abutment part 71 abuts against the inner ring of the bearing 5. The positioning end cover 1 has an annular groove 12 on the side near the bottom cover 7. The ring block 72 rotates with the annular groove 12. The tool holder 2 is threadedly connected to a locking block 24. The locking block 24 abuts against the bottom cover 7. The bottom cover 7 is located between the locking block 24 and the bearing 5.

[0040] The implementation principle of a plate chamfering tool in this application embodiment is as follows:

[0041] The sheet metal is placed in the chamfering area 23, with both ends of the sheet metal abutting against the inner walls of the two chamfering grooves 32. The milling machine clamps the thin end of the cutter bar 2 and starts the milling machine, causing the cutter bar 2 to rotate at high speed around its own axis. This rotation of the cutter bar 2, along with the first cutter head 21, the second cutter head 22, and all the cutting blades 3, allows the cutting blades 3 on the first cutter head 21 and the cutter heads on the second cutter head 22 to simultaneously chamfer both ends of the sheet metal, improving the efficiency of chamfering. After both ends of the sheet metal are chamfered, the sheet metal is moved so that the un-chamfered ends abut against the inner walls of the chamfering grooves 32, reducing the number of times the sheet metal is moved and improving the overall efficiency of chamfering the sheet metal.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
