DETAILED DESCRIPTION
[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0034] Please see attached Figure 1 and Figure 2 The utility model provides a round tube and round rod chamfering device, comprising a plurality of cutters 100, wherein the plurality of cutters 100 are located on the circumference of the same circle, and any of the cutters 100 extends along the diameter direction of the circle; the cutter 100 comprises a cutter seat 110 and a cutter head 120, wherein the cutter head 120 is located on one side of the cutter seat 110, and a first cutter edge 121 and a second cutter edge 122 are respectively arranged on one side of the cutter head 120, wherein one end of the first cutter edge 121 is connected to one end of the second cutter edge 122, and the other end of the first cutter edge 121 extends toward one end of the cutter head 120, and the other end of the second cutter edge 122 extends toward the other end of the cutter head 120; wherein the first cutter edge 121 is arranged at an angle to the cutter seat 110, and the second cutter edge 122 is arranged at an angle to the cutter seat 110.
[0035] When using, as shown in the attached Figure 3 and Figure 4As shown; when a round rod is chamfered, the end of the round rod contacts the first knife edge 121, and the center of the circle is located on the axis of the round rod. When the round rod and the tool 100 are axially relatively close, a depression is formed at the end of the round rod under the action of the first knife edge 121, and the chamfering operation of the end of the round rod is completed by a plurality of tools 100 performing rotational motion along the axis of the round rod; when the inner wall of a round tube is chamfered, the outer edge of the end of the round tube contacts the second knife edge 122, and the center of the circle is located on the axis of the round tube. When the round tube and the tool 100 are axially relatively close, a depression is formed at the end of the round tube under the action of the second knife edge 122, and the chamfering operation of the end of the round tube is completed by a plurality of tools 100 performing rotational motion along the axis of the round tube.
[0036] Therefore, the tool 100 can be used for both external chamfering of round bars and internal chamfering of round tubes through the structural design, without the need to replace the tool. Compared with manual chamfering, the tool 100 has higher dimensional accuracy, lower operating difficulty, and higher chamfering efficiency. Since the device does not require manual chamfering, it effectively avoids safety accidents of cutting workers.
[0037] Please see attached Figure 5-7 The present application further includes a disc 200, the center of the circle is located on the axis of the disc 200, and the disc 200 is provided with a plurality of guide grooves 210 in an annular shape, and a plurality of the cutting tools 100 are respectively slidably arranged in the plurality of the guide grooves 210. By providing the disc 200, a specific guide groove 210 is provided for the cutting tool 100, so that the cutting tool 100 slides along a predetermined track, thereby improving the chamfering operation accuracy.
[0038] In order to further improve the sliding stability of the tool 100 and increase the contact area between the tool 100 and the disc 200 , fins 140 are respectively provided on both sides of the tool holder 110 , and the two fins 140 correspond to the depressions on the two side walls of the guide groove 210 .
[0039] Furthermore, in order to improve the structural aesthetics of the tool, a tool holder chamfer 111 is provided at one end of the tool holder 110 facing the center of the circle.
[0040] Please see attached Figure 5-7 The present application also includes a turntable 300 that can rotate around its own axis, a turntable seat 310 is provided on one side of the turntable 300, and the disc 200 is seated on the turntable seat 310; the outer edge of the turntable seat 310 is configured as a spiral slide 320; a plurality of blade teeth 130 are provided on the side of the tool holder 110 away from the tool head 120, and the plurality of blade teeth 130 are arranged at intervals along the tool holder 110; wherein the spiral slide 320 is slidably arranged between two adjacent blade teeth 130.
[0041] Specifically, when in use, the turntable 300 is used to drive a plurality of tools 100 to move synchronously, so that the plurality of tools 100 are synchronously moved closer to or farther away from each other, thereby adjusting the chamfer size; by rotating the turntable 300, the turntable seat 310 thereon is driven to rotate, so that the cutter teeth 130 slide along the spiral slide 320. Since the spiral slide 320 is spiral, the distance between any point on it and the center of the turntable 300 is different. Therefore, with the cooperation of the spiral slide 320 and the cutter teeth 130, the tool 100 can slide along the guide groove 210, and finally the distance between the tool 100 and the center of the circle is changed, thereby achieving the purpose of adjusting the chamfer size.
[0042] Please see attached Figure 5-7 The present application further includes a handle 400, which is located on a side of the turntable 300 away from the disc 200 and is fixedly connected to the disc 200 by a fastening bolt 500. The arrangement of the handle 400 facilitates gripping, positioning of the turntable 300, and installation of the disc 200.
[0043] In order to further provide a positioning reference for the turntable 300 and improve the assembly accuracy of the entire device, a handle seat 410 is provided on one side of the handle 400, so that a handle step 430 is formed on one side of the handle 400, and the turntable 300 is seated on the handle step 420. Specifically, a concave notch is formed on the side of the turntable 300 opposite to the handle seat 410, and the notch is matched with the handle step 430, so that the matching area between the turntable 300 and the handle 400 is increased, and the size matching degree of the handle 400 and the turntable 300 is improved.
[0044] In order to further facilitate gripping the handle, conveniently holding or fixing it on an electric drill, a short shaft 430 is provided on one side of the handle 400 away from the handle seat 410. A mounting hole is provided in the middle of the short shaft 430 to facilitate connecting the handle 400 with other external components, which is suitable for different working conditions.
[0045] Please see attached Figure 5-Figure 7 In order to conveniently distinguish the first blade edge 121 from the second blade edge 122 , the angle between the first blade edge 121 and the blade seat 110 is greater than the angle between the second blade edge 122 and the blade seat 110 .
[0046] In order to reduce the difficulty of rotating the turntable 300 , an outer surface of the turntable 300 is provided with an anti-slip pattern.
[0047] In summary, the round tube and round rod chamfering device of the present application reduces the chamfering time, avoids the safety risk of cutting operators, and improves manual work efficiency and product quality.
[0048] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
