Description
Technical Field
[0001] This utility model belongs to the technical field of chamfering devices, specifically relating to a chamfering device for mechanical parts. Background Technology
[0002] To remove burrs generated during machining and facilitate the assembly of parts, it is usually necessary to chamfer the workpiece. When a chamfering machine is working, the workpiece is placed on the chamfering worktable. The inner angle rotary cutter head cuts the inner angle and the outer angle rotary cutter head cuts the outer angle, which can chamfer round tube-shaped mechanical parts.
[0003] When chamfering, the cutting tips of the inner and outer corners approach the round tube to complete the chamfering work. Currently, the processing of inner and outer corners is sometimes carried out separately, which not only affects the processing efficiency, but also makes it difficult to adjust the size of the processed corners. Utility Model Content

[0010] The outer angle cutter head is fixedly connected to a central column, and the inner angle cutter head is inserted into the central column.
[0011] Both the outer angle cutter and the inner angle cutter are opposite to the clamping cavity, and the front end face of the outer angle cutter is provided with a guide angle to increase the space.
[0012] The beneficial effects of this utility model are:
[0013] The chamfering head assembly includes an outer chamfering head, an inner chamfering head, and a mounting shaft.

[0020] Please see Figures 1-4The present invention provides the following technical solution: it includes a processing base 1, which has a clamping cavity 11 for fixing the workpiece. Both sides of the clamping cavity 11 are provided with drive shafts 12. One end of the drive shaft 12 is fixedly connected to a connecting seat 13. A chamfering head assembly 2 is provided on the outside of the connecting seat 13. The chamfering head assembly 2 includes an outer angle cutter head 21, an inner angle cutter head 22 and a mounting shaft 23. The inner angle cutter head 22 is located inside the outer angle cutter head 21. The front sides of the outer angle cutter head 21 and the inner angle cutter head 22 are respectively provided with a first chamfering surface 211 and a second chamfering surface 221. One end of the mounting shaft 23 passes through the outer angle cutter head 21 and the inner angle cutter head 22. There is a wall thickness passage cavity 26 between the outer angle cutter head 21 and the inner angle cutter head 22 for passing through the workpiece wall.
[0021] In this embodiment: the processing base 1 has a clamping cavity 11 for fixing the workpiece. Drive shafts 12 are provided on both sides of the clamping cavity 11. One end of the drive shaft 12 is fixedly connected to a connecting seat 13, fixing the workpiece within the clamping cavity 11. The drive shaft 12 drives the connecting seat 13 to rotate and approach the workpiece, where a chamfer is applied by a cutting head. The chamfering head assembly 2 includes an outer chamfering head 21, an inner chamfering head 22, and a mounting shaft 23. The outer chamfering head 21 and inner chamfering head 22 have various specifications, allowing for the processing of different parts and improving the applicability of the device. The inner chamfering head 22 is located inside the outer chamfering head 21. A first chamfering surface 211 and a second chamfering surface 221 are respectively provided on the front sides of the outer chamfering head 21 and the inner chamfering head 22. The first chamfering... Surface 211 and the second chamfered surface 221 form a processing area that contacts the workpiece. One end of the mounting shaft 23 passes through the outer angle cutter head 21 and the inner angle cutter head 22. There is a wall thickness cavity 26 between the outer angle cutter head 21 and the inner angle cutter head 22 for passing through the workpiece wall. The outer angle cutter head 21 and the inner angle cutter head 22 are positioned opposite the workpiece. Under the rotation of the outer angle cutter head 21 and the inner angle cutter head 22, the outer angle and inner angle of the workpiece are chamfered respectively. The mounting shaft 23 is then pulled out, and the outer angle cutter head 21 and the inner angle cutter head 22 can be removed from the connecting seat 13. New specifications of outer angle cutter head 21 and inner angle cutter head 22 can be installed for use. This allows the processing of inner and outer angles to be carried out simultaneously, improving processing efficiency and facilitating the adjustment of the size of the processed corners, which is beneficial for processing round tube-shaped mechanical parts.
[0022] The inner angle cutter head 22 has a second positioning hole 222, and the outer angle cutter head 21 has a first positioning hole 212. The mounting shaft 23 is located in the first positioning hole 212 and the second positioning hole 222. By inserting the mounting shaft 23 into the first positioning hole 212 and the second positioning hole 222, the positions of the outer angle cutter head 21 and the inner angle cutter head 22 can be positioned.
[0023] Two nut washers 24 are fixedly connected to the outer side of the outer angle cutter head 21. A nut is threadedly connected to the outer wall of the mounting shaft 23, and the nut is located outside the nut washers 24. The mounting shaft 23 has external threads, which can be locked onto the mounting shaft 23 to fix the position of the mounting shaft 23.
[0024] A central column is fixedly connected to the outside of the connecting seat 13. The outer angle cutter head 21 is inserted into the central column, and the inner angle cutter head 22 is fixedly connected to the central column. The positions of the outer angle cutter head 21 and the inner angle cutter head 22 can be positioned by inserting the central column, avoiding the need for alignment when installing the outer angle cutter head 21 and the inner angle cutter head 22, and improving the processing efficiency.
[0025] A positioning plate 25 is fixedly connected to the outside of the connecting seat 13, and one end of the mounting shaft 23 is inserted into the positioning plate 25. When the mounting shaft 23 passes through the outer angle cutter head 21 and the inner angle cutter head 22, one end of it can be inserted into the positioning plate 25, so that the positioning plate 25 connected to the connecting seat 13 and the mounting shaft 23 cooperate to stabilize the position of the outer angle cutter head 21 and the inner angle cutter head 22.
[0026] Both the outer angle cutter head 21 and the inner angle cutter head 22 are opposite to the clamping cavity 11. The front end face of the outer angle cutter head 21 is provided with a guide angle to increase the space. The workpiece is fixed in the clamping cavity 11. When the outer angle cutter head 21 moves towards the workpiece, the guide angle has space to avoid it, so that the first chamfered surface 211 can contact the workpiece.
[0027] The working principle and usage process of this utility model are as follows: The workpiece is fixed in the clamping cavity 11. The drive shaft 12 drives the connecting seat 13 to rotate and approach the workpiece to perform chamfering through the cutting head. The chamfering head assembly 2 includes an outer chamfering head 21, an inner chamfering head 22, and a mounting shaft 23. The inner chamfering head 22 is located inside the outer chamfering head 21. The front sides of the outer chamfering head 21 and the inner chamfering head 22 are respectively provided with a first chamfering surface 211 and a second chamfering surface 221. The first chamfering surface 211 and the second chamfering surface 221 form the processing area in contact with the workpiece. One end of the mounting shaft 23 passes through the outer chamfering head 21 and the inner chamfering head. 22. There is a wall thickness cavity 26 between the outer angle cutter head 21 and the inner angle cutter head 22 for passing through the workpiece wall. When the outer angle cutter head 21 and the inner angle cutter head 22 are facing the workpiece, the outer angle and inner angle of the workpiece are beveled respectively under the rotation of the outer angle cutter head 21 and the inner angle cutter head 22. Then, the mounting shaft 23 is pulled out, and the outer angle cutter head 21 and the inner angle cutter head 22 can be removed from the connecting seat 13. New specifications of outer angle cutter head 21 and inner angle cutter head 22 can be installed for use. This allows the processing of inner and outer angles to be carried out simultaneously, improving processing efficiency and facilitating the adjustment of the size of the processed corners, which is beneficial for processing round tube mechanical parts.
