Description

Technical Field

[0001] This utility model relates to the field of chamfering tool technology, and more specifically to a high-efficiency combined chamfering tool. Background Technology

[0002] A chamfering cutter is a tool mounted on milling machines, drilling machines, planers, chamfering machines, etc., used to process 60-degree or 90-degree chamfers, tapered holes, and chamfered edges on workpieces. It is also called a chamfering tool. During the chamfering process, by controlling the chamfering depth and feed rate, the main chamfering edge and the side chamfering edge of the tool chamfer the bevel and edge of the workpiece respectively, achieving precise machining of beveled holes. It removes sharp edges at workpiece edges or openings, preventing scratches or damage to other parts and operators; by processing chamfers, the edges of the workpiece become smoother, improving the overall appearance quality; chamfers can reduce friction during assembly, making parts easier to align and install, improving assembly efficiency and accuracy; and it reduces stress concentration, improving the mechanical properties of the workpiece and extending its service life.

[0003] For example, the chamfering tool disclosed in the prior art, CN222370549U, allows the chamfering tool to be easily replaced by pulling a lever on the outer surface of the limiting cylinder, which in turn causes the limiting block and the limiting latch to slide on the inner surface of the limiting groove. Furthermore, through the connecting mechanism, the chamfering tool can be well fixed to the connection point under the action of the connecting plate.

[0004] However, the existing technology described above still has the following problems in use: when using traditional chamfering cutters, only one type of chamfering cutter can be installed in each mounting hole, so frequent disassembly and reinstallation are required, which is time-consuming and laborious, and also affects the chamfering efficiency. Different types of chamfering cutters cannot be efficiently combined. Based on this, this utility model provides a highly efficient combination chamfering cutter. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a high-efficiency combined chamfering cutter. By setting two cutter bodies on the rotating rod, it can be quickly combined into a double-headed chamfering cutter for use. This allows the operator to quickly rotate the chamfering cutter head to switch between them, which not only improves chamfering efficiency and increases operational selectivity, but also allows for direct switching between the chamfering cutter heads for continuous operation if two identical chamfering cutter heads are selected. Damaged chamfering cutter heads can then be replaced uniformly after the chamfering work is completed, effectively optimizing the operation process and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency combined chamfering tool, including a tool holder, the tool holder including a rotating rod, two tool bodies sleeved on the outer wall of the rotating rod, each tool body including a chamfering tool rod and a chamfering tool head, mounting plates fixedly provided at both ends of the rotating rod, the two chamfering tool rods being disposed between the two mounting plates, and baffles provided on the outer walls of the two chamfering tool rods, the baffles being connected to the mounting plates via rotating shafts, and the two baffles being detachably connected to the mounting plates via first bolts.

[0007] In a preferred embodiment, a first circular groove is provided on the surface of the two baffles on the side away from each other, and the first bolt is located in the first circular groove to avoid the first bolt protruding outward and affecting the appearance.

[0008] In a preferred embodiment, each of the two cutter bodies has a semi-circular groove near the end of the rotating rod. The inner wall of the semi-circular groove contacts the outer wall of the rotating rod. Each of the two chamfering cutter bars has multiple second circular grooves on the opposite side. Each second circular groove contains a second bolt. The second bolt passes through the chamfering cutter bar and fixes the two chamfering cutter bars, making it easy to disassemble and replace the chamfering cutter head.

[0009] In a preferred embodiment, the two mounting plates are threadedly connected to a third bolt on the opposite side. The front end of each of the two chamfering cutter bars is provided with a threaded hole that matches the third bolt. The third bolt is located in the threaded hole and threadedly connected to the threaded hole. The chamfering cutter bar is fixed by the cooperation of the third bolt and the threaded hole, which can further improve the stability of the chamfering cutter head.

[0010] In a preferred embodiment, a third circular groove is provided on the side of the two mounting plates that are far apart. The third bolt is located inside the third circular groove. After the third bolt is tightened, it is embedded in the third circular groove, which can prevent the third bolt from protruding outward and affecting the appearance.

[0011] In a preferred embodiment, each of the first, second, and third circular grooves has a rubber sealing ring bonded to its inner wall to improve the sealing performance between the first, second, and third bolts and the first, second, and third circular grooves, respectively.

[0012] In a preferred embodiment, both mounting plates are provided with a plurality of evenly distributed rectangular through holes, and the plurality of rectangular through holes are all located on the outside of the third circular groove. The provision of a plurality of rectangular through holes facilitates the fixing of the mounting plates and improves the stability of the mounting plates.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model sets two cutter bodies on the rotating rod, which can be quickly combined into a double-headed chamfering cutter. This allows the operator to quickly rotate the chamfering cutter head to switch between them, which can improve chamfering efficiency and increase operational options. If two chamfering cutter heads of the same model are selected, the chamfering cutter heads can be switched directly during use for continuous operation. After the chamfering work is completed, the damaged chamfering cutter head can be replaced at the same time, which effectively optimizes the operation process.

[0015] 2. By setting two baffles on the left and right sides of the chamfering cutter bar to limit movement, the stability of the chamfering cutter head during use can be improved, thereby improving the chamfering quality and efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5This utility model provides a high-efficiency combined chamfering tool, including a tool holder 1. The tool holder 1 includes a rotating rod 101. Two tool bodies 2 are sleeved on the outer wall of the rotating rod 101. The tool body 2 includes a chamfering tool rod 201 and a chamfering tool head 202. Mounting plates 102 are fixedly provided at both the front and rear ends of the rotating rod 101. The two chamfering tool rods 201 are both located between the two mounting plates 102.

[0024] Both cutter bodies 2 have a semi-circular groove 7 near one end of the rotating rod 101. The inner wall of the semi-circular groove 7 is in contact with the outer wall of the rotating rod 101. Both chamfering cutter rods 201 have multiple second circular grooves 8 on the opposite side. Each second circular groove 8 has a second bolt 9. The second bolt 9 passes through the chamfering cutter rod 201 and fixes the two chamfering cutter rods 201.

[0025] Both mounting plates 102 have multiple evenly distributed rectangular through holes 14, and the multiple rectangular through holes 14 are all located on the outside of the third circular groove 12. The multiple rectangular through holes 14 facilitate the fixing of the mounting plates 102 and improve the stability of the mounting plates 102.

[0026] In actual use, two chamfering cutter bars 201 are fitted onto the outer wall of the rotating rod 101 and connected together. The chamfering cutter heads 202 on the two chamfering cutter bars 201 are of different models, so they can be combined to form a double-headed chamfering cutter for use. This allows the operator to quickly rotate the chamfering cutter head 202 to switch between them, improving chamfering efficiency. Alternatively, the two chamfering cutter heads 202 can be of the same model. When one of the chamfering cutter heads 202 is damaged and cannot continue chamfering, the operator only needs to switch between the two chamfering cutter heads 202. After the chamfering work is completed, the damaged chamfering cutter head 202 is replaced.

[0027] Refer to the instruction manual appendix Figure 1 , Figure 2 , Figure 3 and Figure 5 Both chamfering tool holders 201 have baffles 3 on their outer walls. The baffles 3 are connected to the mounting plate 102 via a rotating shaft 4. Both baffles 3 are detachably connected to the mounting plate 102 via first bolts 5. Both baffles 3 have first circular grooves 6 on their surfaces that are far apart from each other. The first bolts 5 are located in the first circular grooves 6.

[0028] By setting two baffles 3 on the left and right sides of the chamfering cutter bar 201 to limit the movement, the stability of the chamfering cutter head 202 during use can be improved. When it is necessary to switch the positions of the two chamfering cutter heads 202, the operator can loosen the first bolt 5 and then remove the baffles 3.

[0029] like Figures 1-4As shown, a third bolt 10 is threadedly connected to each of the two mounting plates 102 on the opposite side. Each of the two chamfering cutter bars 201 has a threaded hole 11 at its front end that matches the third bolt 10. The third bolt 10 is located within and threadedly connected to the threaded hole 11. A third circular groove 12 is also provided on each of the two mounting plates 102 on the opposite side, and the third bolt 10 is located inside the third circular groove 12. The chamfering cutter bar 201 is fixed by the cooperation of the third bolt 10 and the threaded hole 11, which further improves the stability of the chamfering cutter head 202. Furthermore, after the third bolt 10 is tightened, it is embedded in the third circular groove 12, preventing the third bolt 10 from protruding outwards and affecting the aesthetics.

[0030] Moreover, such as Figure 3 and Figure 5 As shown, a rubber sealing ring 13 is bonded to the inner wall of each of the first circular groove 6, the second circular groove 8 and the third circular groove 12 to improve the sealing between the first, second and third bolts 10 and the first, second and third circular grooves 12 respectively. Since the rubber sealing ring 13 is soft, it fits tightly against the first, second and third bolts 10 when they are tightened, which not only improves the sealing performance but also plays a role in preventing loosening to a certain extent.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
