Detailed Description
The utility model is further described below in connection with the examples, which are not to be construed as limiting the utility model in any way, but rather as falling within the scope of the claims.
Referring to fig. 1 to 3, a chamfering device of the present utility model includes a split-type cutter handle 1 and a cutter head 3. The tool handle 1 is detachably arranged at one end of the cutter head 3, so that the tool handle 1 of the chamfering device and the cutter head 3 are disassembled and assembled, and the chamfering device is convenient to maintain and replace damaged parts.
Specifically, the tip of handle of a knife 1 is equipped with mounting panel 2 rather than structure as an organic whole, has seted up the through-hole on the mounting panel 2, has seted up screw hole two on the terminal surface of blade disc 3, has pegged graft the locking bolt in the through-hole, and the locking bolt connects in screw hole two soon, has realized the detachable connection of handle of a knife 1 and blade disc 3.
A conical groove 4 is formed in one end of the cutter disc 3, which is far away from the cutter handle 1. In the embodiment, the conical angle of the conical groove 4 is 90 degrees, so that the chamfer angle of the chamfered pipe end is 45 degrees, and the problem that most chamfering devices on the market at present are 30 degrees in chamfer angle and cannot pour out 45-degree chamfer angle requirements is solved.
Eight insert grooves 5 are provided in the conical groove 4, and the eight insert grooves 5 are uniformly distributed in the conical groove 4 with the apex of the conical groove 4 as the midpoint. A chamfer insert 6 is inserted into all insert pockets 5. The edge of the chamfering blade 6 located in the blade groove 5 is 0.5mm higher than the conical surface of the conical groove 4 so that the chamfer surface width of the pipe end poured out is 1mm. The chamfer insert 6 is made of a white steel bar. The white steel bar has the characteristics of convenient purchase and easy processing, and can effectively reduce the cost of the chamfering device.
A wedge block self-locking mechanism for tightly propping and positioning the chamfering blade 6 is arranged in the cutter head 3 at one side of the chamfering blade 6. Through the effect of voussoir self-locking mechanism, realized locking and unblock to chamfer blade 6, make it be convenient for dismouting. When one or more of the chamfering blades 6 are damaged, only the corresponding chamfering blade 6 needs to be replaced, and the whole replacement is not needed.
Specifically, the wedge block self-locking mechanism comprises a first wedge block 8, a second wedge block 9 and a tightening bolt. A square notch 7 communicated with the cutter head 3 at one side of the cutter blade groove 5 is formed in the cutter head 3, the first wedge block 8 and the second wedge block 9 are arranged in the square notch 7 in a staggered mode, and the wedge faces of the first wedge block 8 and the second wedge block 9 are attached. One side surface of the first wedge block 8 is attached to the side surface of the chamfering blade 6 in the blade groove 5, and one side surface of the second wedge block 9 is attached to the side wall of the square notch 7 away from the blade groove 5. The side wall of the cutter head 3 is provided with a first threaded hole 10 communicated with the square notch 7, and the axial direction of the first threaded hole 10 is consistent with the sliding direction of the wedge faces of the two wedge blocks. The jacking bolt is screwed in the threaded hole I10, and the jacking bolt is jacked at one end of the wedge-shaped block II 9.
The jacking screw is jacked on the second wedge-shaped block 9. When the jacking bolt is screwed in the axial direction of the cutter head 3, the wedge faces of the two wedge blocks slide to increase the contact area of the jacking bolt, so that the second wedge block 9 jacks the first wedge block 8 in the direction of the chamfering blade 6, and the chamfering blade 6 is more stably fixed in the cutter head 3.
The working principle of the utility model is as follows: the cutterhead 3 is inverted and the chamfer insert 6 is placed in the insert pocket 5 and two wedge-shaped blocks are placed in the square cutout 7. Then, a tightening bolt is selected from the first threaded hole 10, and the second wedge 9 is tightened by the tightening bolt to fix the chamfer insert 6 in the insert pocket 5. And then the cutter head 3 is turned over, and the cutter handle 1 is fixed on the cutter head 3 through a locking bolt. When the chamfering tool is used, the axis of the chamfering tool is consistent with the axis of a pipe to be chamfered, then the chamfering tool is close to the pipe end, and when the chamfering blade 6 is in contact with the pipe end, the pipe end can be chamfered.
While only the preferred embodiments of the present utility model have been described above, it should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these do not affect the effect of the implementation of the present utility model and the utility of the patent.
