Abstract
The utility model discloses a chamfering and deburring tool for a through inner hole. The chamfering and deburring tool comprises a rotary rod, an expansion rod, a pawl, a ratchet wheel and a pressure lever. The head portion of the rotary rod is provided with a flexible hinge and a carbide blade is brazed to the end of the flexible hinge; the expansion rod, the pawl and the ratchet wheel are respectively arranged in an inner hole of the rotary rod; the ratchet wheel is installed on the upper portion of the expansion rod; the pawl is arranged above the ratchet wheel and matched with the ratchet wheel; the pressure lever is fixed to the pawl. Before the chamfering and deburring tool is used and after all parts are assembled, the parts do not need to be disassembled in the later use process; when the chamfering and deburring tool is used, only the pressure lever needs to be pressed so that the carbide blade can stretch out and contract back; the carbide blade stretches into the hole to be machined when the carbide blade contracts back, and chamfering or deburring is conducted by rotating the chamfering and deburring tool when the carbide blade stretches out; after machining is completed, the pressure lever is pressed secondarily so that the chamfering and deburring tool can be taken out; thus, the whole machining process is convenient and the machining efficiency is high.
Description
Technical field
The utility model relates to a kind of for passing through mutually chamfering, the deburring tool of endoporus.
Background technology
In mechanical field, have that to pass through mutually the part kind of inner hole structure very huge, for example: in the camshaft in diesel engine, bent axle, piston pin, particularly hydraulic system, relate to hydraulic valve, hydraulic workstation etc., inner phase perforation is many especially.Before assembling, must carry out chamfering or deburring to passing through mutually endoporus.All be positioned at inside parts because endoporus passes through out mutually, various tool is difficult to stretch in hole, and particularly endoporus aperture is less, the degree of depth is darker, is difficult to especially realize.At present, in market, have some deburring tools, but these tool insert rigidity are too low, cannot realize the processing of larger chamfering, can only be with removing burr.
Utility model content
The purpose of this utility model is to provide a kind ofly can process the universal tool that passes through mutually inner bore chamfering, deburring efficiently.
The technical scheme that realizes the utility model object is: a kind of for passing through mutually chamfering, the deburring tool of endoporus, comprise swingle, expansion rod, ratchet, ratchet and depression bar; Described swingle head is processed with flexible hinge, and the end soldering of flexible hinge has carbide chip; Described expansion rod, pawl-and-gearing are all arranged in the endoporus of swingle; Described ratchet is arranged on the top of expansion rod; Described ratchet is arranged on ratchet top and coordinates with it; Described depression bar is fixed on ratchet.
In the endoporus of described swingle, be provided with the three equally distributed directive slide tracks in road; The equally distributed groove in Excircle machining You San road of described ratchet; Directive slide track in groove on the cylindrical of described ratchet and the endoporus of swingle is slidably connected.
Described swingle is provided with strut kong; Described depression bar is through strut kong.
Adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model before use, all Assembly of the parts are good after, in later use procedure without dismounting; In use, only depression bar need be pressed, stretching out and retracting of alloy blade can be realized, when retraction, stretch in hole to be processed, rotatable chamfering or deburring while stretching out, after machining, again press depression bar and can take out this instrument, whole process is easy to operate, and working (machining) efficiency is high.
(2) directive slide track in the endoporus of the groove on the cylindrical of ratchet of the present utility model and swingle is slidably connected, this structure can keep the stability of operation, and the length that changes directive slide track, just can realize the chamfering of different size is processed.
(3) the utility model, by changing the shape of alloy blade, can process straight chamfering or rounded corner.
(4) the utility model highly versatile, can be clamped in various throws and use.

Detailed description of the invention
(embodiment 1)
See Fig. 1 to Fig. 3, the present embodiment for passing through mutually chamfering, the deburring tool of endoporus, comprise swingle 1, expansion rod 2, ratchet 3, ratchet 4 and depression bar 5.
Swingle 1 head is processed with flexible hinge 12, and the end soldering of flexible hinge 12 has carbide chip 11.Expansion rod 2, ratchet 3 and ratchet 4 are all arranged in the endoporus of swingle 1.Ratchet 4 is arranged on the top of expansion rod 2.In the endoporus of swingle 1, be provided with the three equally distributed directive slide tracks 13 in road.The equally distributed groove in Excircle machining You San road of ratchet 4.Directive slide track 13 in the endoporus of the groove on the cylindrical of ratchet 4 and swingle 1 is slidably connected.Ratchet 3 is arranged on ratchet 4 tops and coordinates with it.Swingle 1 is provided with strut kong 14, and depression bar 5 is fixed on ratchet 4 through strut kong 14.
See Fig. 4, the present embodiment for passing through mutually the chamfering of endoporus, the course of work of deburring tool is: this instrument is arranged on to electric grinding machine, presses depression bar 5, the alloy blade 11 on swingle 1 is retracted; Then this instrument is stretched in the endoporus of workpiece 6, make flexible hinge 12 be positioned at workpiece 6 endoporus pass through mutually place; And then press depression bar 5, and expansion rod 2 deforms the flexible hinge 12 of swingle 1, and alloy blade 11 stretches out; Then start sander, driven rotary bar 1 rotates; Then pull out outward this instrument by certain speed, alloy blade 11 starts to cut phase perforation place chamfering; After machining, close sander, and then press depression bar 5, alloy blade 11 is retracted, and this instrument is taken out from hole, completes whole process.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
