Abstract
The utility model discloses a machining tool for an eccentric shaft. The machining tool for the eccentric shaft comprises a first clamping block and a second clamping block. The first clamping block comprises a base seat and a clamping block, wherein the base seat and the clamping block are circular cylinders with the same axis, and the clamping block is arranged on the base seat. A hole groove is arranged 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 of a circular ring shape, and an eccentric distance is arranged between a circle center of an outer circle of the second clamping block and a circle center of an 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 with the eccentric distance between the circle center of the outer circle of the second clamping block and the circle center of the inner circle of the second clamping block. According to the way, the machining tool for the eccentric shaft can machine the eccentric shaft rapidly, simply and conveniently, improves the machining efficiency, lowers the labor cost, improves the production capacity and is suitable for mass production.
Description
Technical field
The utility model relates to the frock clamp field, particularly relates 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.
The utility model content
The technical problem that the utility model 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 utility model 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 beneficial effects of the utility model are: the processing eccentric shaft that the utility model can be fast and convenient, and 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 utility model is used processing tool and workpiece mated condition;
To be a kind of eccentric shaft of the utility model 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 utility model 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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1 to Fig. 3, the utility model embodiment 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 embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification 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 utility model.
