Abstract
The invention discloses a novel crankshaft machining fixture, which is characterized in that a fixture body is provided with an eccentric workpiece hole inside, a transverse through hole is reserved on a thick-wall side of the eccentric workpiece hole, a lock screw is inserted into the through hole and provided with an arc matched with the outer periphery of a workpiece, and the lock screw is fixed through two fixing screws. Therefore, the novel crankshaft machining fixture can be used for machining the external periphery of a crankshaft. The novel crankshaft machining fixture can be used for more stably mounting and clamping the crankshaft, the problem of low positioning precision is solved, machining precision is improved, machining efficiency is improved, and product machining quality is improved.
Description
Technical field
The present invention relates to a kind of machined into and use frock, be specifically related to a kind of new type crank processing tool.
Background technology
Bent axle processing clamping location in the past mainly is the punching two ends location at bent axle, adopts this mode to exist the centre bore location difficult, is difficult to be on the same axis, and working (machining) efficiency is low, and machining accuracy is not high, influences many defectives and unfavorable factors such as product quality.
Summary of the invention
The object of the invention is to provide a kind of new type crank processing tool.
To achieve these goals; The present invention is provided with the eccentric work piece hole in the inside of clamp body, and the wall thickness side in the eccentric work piece hole is horizontally arranged with through hole, in through hole, is interspersed with lock-screw; On said lock-screw, be provided with the circular arc that matches with the workpiece external diameter, two hold-down screws are fixed lock-screw.
Through above setting, the two ends that need machining crankshafts are inserted respectively in two eccentric work piece of the present invention holes and fixing, two the present invention cooperate with the chuck and the thimble of lathe, can realize the cylindrical of bent axle is processed.It is more firm that the present invention installs the clamping bent axle, separates decision bit inaccuracy problem, promotes machining accuracy, improves working (machining) efficiency, improves product processing quality.
Description of drawings

Among the figure: 1, clamp body, 2, the eccentric work piece hole, 3, through hole, 4, lock-screw, 5, hold-down screw.
The specific embodiment
Like Fig. 1, shown in 2; The present invention is provided with eccentric work piece hole 2 in the inside of clamp body 1; Wall thickness side in eccentric work piece hole 2 is horizontally arranged with through hole 3; In through hole 3, be interspersed with lock-screw 4, on said lock-screw 4, be provided with the circular arc that matches with the workpiece external diameter, two hold-down screws 5 are fixing with lock-screw 4.Through above setting, the two ends that need machining crankshafts are inserted respectively in two eccentric work piece of the present invention holes 2, and fixing with lock-screw 4 with hold-down screw 5, two the present invention cooperate with the chuck and the thimble of lathe, can realize the cylindrical processing to bent axle.
