Abstract
The invention discloses a processing tool for an eccentric shaft, which comprises: the clamping device comprises a first clamping block and a second clamping block, wherein the first clamping block comprises a base and a clamping block, the base and the clamping block are coaxial cylinders, the clamping block is arranged on the base, a hole groove is formed in the clamping block, and an eccentric distance is arranged between the center of the hole groove and the axis of the clamping block; the second clamping block is in a circular ring shape, and an eccentric distance is arranged between the circle center of the outer circle and the circle center of the inner circle of the second clamping block; the eccentric distance between the center of the hole groove and the axis of the clamping block is the same as the eccentric distance between the outer circle and the inner circle center of the second clamping block. Through the mode, the eccentric shaft machining device can quickly, simply and conveniently machine the eccentric shaft, improves machining efficiency, reduces labor cost, improves productivity, and is suitable for mass production.
Description
Technical field
The present invention relates to the frock clamp field, particularly relate to a kind of eccentric shaft processing tool.
Background technology
Traditional eccentric shaft processing method has two kinds, a kind of method is to adopt jig boring machine in the method for the two ends of axle centering and eccentric centre bore, impracticable in the very little situation of eccentric throw, the eccentric throw precision of eccentric shaft depends on the precision of institute's centering and eccentric centre bore, in case centre bore and eccentric central hole location are determined just can not adjust again; Another kind of processing method is at axle two ends centering, finishes with the crankshaft grinding machine grinding, and machining accuracy is high, but needs special-purpose crankshaft grinding machine, and cost is higher; Also having a kind of is to process eccentric work piece at tri-claw disk or four paws dish, and this precision of method is low, and workpiece of every processing will be reorientated, and efficient is low.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of eccentric shaft processing tool, and processing eccentric shaft that can be fast and convenient improves working (machining) efficiency and reduces labour cost, has improved production capacity, also is suitable for producing in enormous quantities.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of eccentric shaft processing tool is provided, comprise: the first fixture block and the second fixture block, described the first fixture block comprises pedestal and fixture block, described pedestal and fixture block are that cylinder and the fixture block of concentric is located on the pedestal, be provided with hole slot at fixture block, be provided with eccentric throw between the center of described hole slot and the fixture block axle center; Described the second fixture block is circular, is provided with an eccentric throw between the center of circle of the second fixture block cylindrical and inner circle; The eccentric throw in described hole slot center and fixture block axle center is identical with the eccentric throw in the second fixture block cylindrical and the inner circle center of circle.
Preferably, described pedestal is equipped with centre bore on the axle center, and the hole slot of described fixture block is an imperfect circle, is provided with a fixing hole at the fixture block periphery.
Preferably, described the second fixture block is provided with an opening in the position of the exradius in the process fixture block inner circle center of circle.
The invention has the beneficial effects as follows: the processing eccentric shaft that the present invention can be fast and convenient, improve working (machining) efficiency and reduce labour cost, improved production capacity, also be suitable for producing in enormous quantities.
Description of drawings
Fig. 1 is the schematic diagram that a kind of eccentric shaft of the present invention is used processing tool and workpiece mated condition;
To be a kind of eccentric shaft of the present invention look schematic diagram with the master of processing tool the first fixture block to Fig. 2;
To be a kind of eccentric shaft of the present invention look schematic diagram with the master of processing tool the second fixture block to Fig. 3;
The mark of each parts is as follows in the accompanying drawing: 1, the first fixture block; 2, workpiece to be processed; 3, the second fixture block; 4, pedestal; 5, fixture block; 6, hole slot; 7, cylindrical; 8, inner circle; 9, opening.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 to Fig. 3, the embodiment of the invention comprises:
A kind of eccentric shaft processing tool, comprise: the first fixture block 1 and the second fixture block 3, described the first fixture block 1 comprises pedestal 4 and fixture block 5, described pedestal 4 and fixture block 5 are located on the pedestal 4 for the cylinder of concentric and fixture block 5, be provided with hole slot 6 at fixture block 5, be provided with eccentric throw between the center of described hole slot 6 and fixture block 5 axle center; Described pedestal is equipped with centre bore on 4 axle center, and the hole slot 6 of described fixture block 5 is an imperfect circle, is provided with a fixing hole at fixture block 5 peripheries; Described the second fixture block is circular, is provided with an eccentric throw between the center of circle of the second fixture block cylindrical 7 and inner circle 8; The eccentric throw in described hole slot 6 centers and fixture block 5 axle center is identical with the eccentric throw in the second fixture block cylindrical 7 and inner circle 8 centers of circle; Described the second fixture block is provided with an opening 9 in the position of cylindrical 7 radiuses in process inner circle 8 centers of circle.
When the processing eccentric shaft, the two ends of workpiece to be processed are clipped in respectively between the inner circle 8 of the hole slot 6 of the first fixture block 1 and the second fixture block 3, so that the center of circle of the center of the axle center of workpiece and hole slot and the second fixture block inner circle is on logical straight line, adding between the axle center of the pivot of clamp for machining in man-hour and workpiece has an eccentric throw, thereby finishes the processing of eccentric shaft.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
