Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, there is provided a kind of instrument, use instrument to remove clean by sharp edge and burr, the stress that minimizing connecting rod passes through place mutually in holes is concentrated, thus avoid connecting rod fatigue fracture, thus ensure product quality and service life.
A kind of deburring tool, specifically comprises: the knife bar 5 of strip and be located at the cutter head 6 of knife bar front end of strip, and cutter head has triangular scraper parts, and described knife bar 5 head has a fluting, and knife rod head is divided into two parts; Tapering hole slot is also had in the head end inside of knife bar, tapering hole slot is built with a pull bar 4, the head of this pull bar has a conical surface, the cone match of described tapered hole and pull bar 4 head, wherein, described pull bar 4 is reciprocable in described tapering hole slot, and controls opening and closing of knife bar by moving back and forth.
Further, preferably, the afterbody of described knife bar 5 connects a box spanner 1, and pull bar 4 connects an adjustment plug screw 3, described adjustment plug screw 3 is located in the tapering hole slot of knife bar inside, and adjustment plug screw 3 is moved back and forth in tapering hole slot by the counterclockwise or control pull bar 4 that turns clockwise in knife bar 5.
Further, preferably, described box spanner 1 has a cubic endoporus, and the outside of adjustment plug screw 3 has an outer cubic limit, described cubic inner hole sleeve on described outer cubic limit, to regulate the rotary motion of adjustment plug screw 3.
Further, preferably, adjust between plug screw 3 and pull bar 4 and also connect a pad 2.
Further, preferably, described cutter head 6 is welded on knife bar 5.
Further, preferably, the maximum gauge of described cutter head 6 is less than the aperture, inside of the parts wanting deburring.
After the utility model takes above scheme, can remove clean by sharp edge and burr better, the stress that minimizing connecting rod passes through place mutually in holes be concentrated, thus avoids connecting rod fatigue fracture, thus ensures product quality and service life.
Specifically, this instrument is mainly made up of box spanner 1, pad 2, adjustment plug screw 3, pull bar 4, knife bar 5, cutter head 6.
Wherein, cutter head 6 is welded on knife bar 5, and the triangle portion of cutter head has blade, and blade is used to anti-burr of scraping.The head of knife bar 5 has fluting, knife rod head is divided into 2 parts by fluting, and the head of knife bar has tapering hole slot, tapering hole slot built with pull bar 4 and with pull bar 4 head cone match, when pull bar 4 moves to handle of a knife direction in knife bar 5, the pull bar 4 head conical surface can by tapering hole slot spreading, when pull bar 4 in knife bar 5 to head movement time, then tapering hole slot shrinks and restores.
Pull bar 4 pulls to the motion of handle of a knife direction by the motion of adjustment plug screw 3, pad 2 and pull bar 4 weld together, when adjusting plug screw 3 and rotating in knife bar 5, adjustment plug screw 3 is with mobile gasket 2 and pull bar 4 to move to handle of a knife direction, when adjusting plug screw 3 in knife bar 5 during rightabout rotation, then pull bar 4 moves to knife rod head by the tapering hole slot contraction by knife rod head.The cubic inner hole sleeve of box spanner 1, on the outer four directions of adjustment plug screw 3, is used for regulating the rotary motion adjusting plug screw 3.
Wherein, the maximum gauge of cutter head 6 is less than aperture, otherwise cutter head cannot in access aperture, pass through place mutually when cutter head enters into holes, regulate adjustment plug screw 3 to make pull bar 4 by cutter head spreading, the maximum gauge of cutter head 6 is greater than aperture, the blade of cutter head 6 is then towards holes intersection, now knife bar can not pull out in hole, because the blade of cutter head has snapped on holes relation line, has rotated knife bar blade and is then removed by the sharp edge burr on intersection clean.
Key point of the present invention is as follows:
After in 1 knife bar access aperture, cutter head can rise and can contract, and ensures that the blade after spreading is towards intersection, reduces rear light turnover.
The face that 2 rod heads and knife rod head coordinate is the conical surface, and slots on knife bar, and cutter head can be risen can contract.
Effect of the present invention is as follows:
1 structure is simple, and the scope of application is wide: this tool construction is simple, can promote solution Similar Problems.
2 is easy to operate, and efficiency is high: only need rotational sleeve spanner gently, namely the harmomegathus of adjustable cutter head, improves production efficiency.
3 ensure that product quality, improve service life: achieve the removal that inclined hole intersects burr, avoid stress that intersection sharp edge produces and concentrate destruction to connecting rod.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
