Abstract

The utility model discloses an eccentric sleeve keywaying tool which comprises a fixing sleeve and a rectification mandrel. Stepped inner holes are arranged inside the fixing sleeve, and the stepped inner holes comprise an upper end inner hole and a lower end inner hole. The upper end inner hole is used for installation of an eccentric hole of a machined eccentric sleeve, the lower end inner hole is a central hole concentric with the fixing sleeve, and the diameter of the central hole is equal to that of the eccentric hole. A key groove is machined in the inner wall of the lower end inner hole. One end of the rectification mandrel is a hand holding end, and the other end of the rectification mandrel is a rectification end. The diameter of the rectification end is the same as that of the inner hole of the machined eccentric sleeve. The eccentric sleeve keywaying tool can achieve quick machining of the eccentric sleeve key groove, and improves machining efficiency and machining quality of the eccentric sleeve key groove.

The utility model content
The utility model is the weak point that exists in the above-mentioned prior art for avoiding, and a kind of eccentric bushing keyway processing tool is provided, to improve working (machining) efficiency and the quality of eccentric bushing keyway.
The utility model be the technical solution problem by the following technical solutions.
Eccentric bushing keyway processing tool, its design feature are to comprise fixed cover and proofread and correct axle; Be provided with the ladder endoporus in described fixed cover inside, described ladder endoporus comprises upper end endoporus and lower end endoporus; Described upper end endoporus is for being used for installing the eccentric orfice of processed eccentric bushing, and described lower end endoporus is the centre bore concentric with described fixed cover, the diameter of described lower end endoporus and the diameter of bore equal and opposite in direction of described processed eccentric bushing; Be processed with keyway on the inwall of described lower end endoporus; The sidewall of described upper end endoporus is provided with screw;
One end of described correction axle is for holding end, and the other end of described correction axle is for proofreading and correct end; The diameter of described correction end is identical with the diameter of bore of processed eccentric bushing.
The design feature of eccentric bushing keyway processing tool of the present utility model also is:
Be processed with annular knurl on the outer peripheral face of holding end of described correction axle.
Compared with the prior art, the utility model beneficial effect is embodied in:
With fixed cover by being fixedly installed on the slotting machine work top with the disposable tool setting of slotting machine cutter, with eccentric bushing to be processed lay with fixed cover in, utilize the correction axle to proofread and correct eccentric bushing endoporus to be processed concentric with fixed cover below endoporus, lock eccentric bushing to be processed both sides lock-screw and can realize quick production.
Eccentric bushing keyway processing tool of the present utility model has the rapid processing that can realize the eccentric bushing keyway and can greatly enhance productivity and the advantage such as product processing quality.

Fig. 1 is the front view of the fixed cover of eccentric bushing keyway processing tool of the present utility model when eccentric bushing has been installed.
Fig. 2 is the top view of the fixed cover of eccentric bushing keyway processing tool of the present utility model when eccentric bushing has been installed.
Fig. 3 is the cutaway view of fixed cover of the present utility model.
Fig. 4 is the front view of the correction axle of eccentric bushing keyway processing tool of the present utility model.
Label in accompanying drawing 1~accompanying drawing 4: 1 fixed cover, 2 proofread and correct axle, 3 upper end endoporus, 4 lower end endoporus, 5 keyways, 6 hold end, and 7 proofread and correct end, 8 eccentric bushings, 9 annular knurls, 10 screws.
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
The specific embodiment
Referring to Fig. 1~Fig. 4, eccentric bushing keyway processing tool comprises fixed cover 1 and proofreaies and correct axle 2; Be provided with the ladder endoporus in described fixed cover 1 inside, described ladder endoporus comprises upper end endoporus 3 and lower end endoporus 4; Described upper end endoporus 3 is for being used for installing the eccentric orfice of processed eccentric bushing 8, and described lower end endoporus 4 is the centre bore concentric with described fixed cover 1, the diameter of described lower end endoporus 4 and the diameter of bore equal and opposite in direction of described processed eccentric bushing 8; Be processed with keyway 5 on the inwall of described lower end endoporus 4; The sidewall of described upper end endoporus (3) is provided with screw 10;
One end of described correction axle 2 is for holding end 6, and the other end of described correction axle 2 is for proofreading and correct end 7; The diameter of described correction end 7 is identical with the diameter of bore of processed eccentric bushing 8.
Be processed with annular knurl 9 on the outer peripheral face of holding end 6 of described correction axle 2.
Described fixed cover upper end endoporus is eccentric orfice, and the eccentric throw of the eccentric throw of upper end inner hole outer circularity and eccentric bushing to be processed is equal to, and lower end diameter of bore and eccentric bushing diameter of bore to be processed are equal to, and have and the keyway of eccentric bushing to be processed with the orientation.Proofread and correct axle one end and be processed with annular knurl, for holding end; Other end diameter is equal to eccentric bushing endoporus to be processed, fixed cover lower end diameter of bore size, for proofreading and correct end.The sidewall of upper end endoporus is provided with the screw that radially penetrates described fixed cover, lock-screw be used for to be installed eccentric bushing is anchored among the endoporus of described upper end, is convenient to carry out the processing of keyway.
In the use procedure fixed cover is installed on the slotting machine work top, utilize keyway and the disposable tool setting of slotting machine molding cutter in the endoporus of fixed cover below, eccentric bushing to be processed is placed in the fixed cover, utilize to proofread and correct axle square hole correction under eccentric bushing endoporus to be processed and the fixed cover is concentric, lock-screw screws within the screw, eccentric bushing to be processed is fixed in the fixed cover, takes out axle and can realize quick production.In eccentric bushing keyway process, need not single-piece and draw the keyway processing line, need not in the slotting machine process, to repeat the steps such as tool setting, improved widely the working (machining) efficiency of eccentric bushing keyway.
