Abstract

The invention provides a drilling fixture for a cylinder cover, which can effectively improve positioning precision and clamping precision of a workpiece, accordingly guarantees machining precision of the workpiece, can greatly reduce labor intensity of workers, enhances production efficiency and lowers production cost. The drilling fixture comprises a bottom plate, and a fixing plate is vertically mounted on the bottom plate. The drilling fixture is characterized by further comprising a workpiece positioning and clamping device and a plate jig, the workpiece positioning and clamping device is fixed onto a workpiece clamping surface of the fixing plate, the plate jig is connected with the upper end of the fixing plate by a hinge device, and a drill bushing is correspondingly mounted on the plate jig according to a to-be-drilled position of the workpiece.

Description

The boring grab of cylinder cover cap

Technical field

The present invention relates to diesel engine part processing tool field, be specially the boring grab of cylinder cover cap.

Background technology

The cylinder of diesel engine cover cap was holed processing is many is fixed in the radial drilling machine platform through pressing plate with workpiece in the past; Its shortcoming be workpiece the location, clamp unreliable; Machining accuracy is low, and the mode clamping workpiece labor strength that adopts pressing plate to fix is big, production efficiency is low; In addition, to the cylinder cover cap of different model, need the corresponding pressing plate of configuration, its production cost is high.

Summary of the invention

To the problems referred to above, the invention provides the boring grab of cylinder cover cap, its its can effectively improve location, the clamping precision of workpiece, thereby guarantee the workpiece machining accuracy, and can reduce labor strength greatly, enhance productivity, reduce production costs.

Its technical scheme is such; It comprises base plate; Be vertically installed with fixed head on the said base plate, it is characterized in that: it also comprises the tight device of work piece positioning and bores template die that the tight device of said work piece positioning is fixed in the clamping workpiece face of said fixed head; Said brill template die is connected with the upper end of said fixed head through hinge means, and the bore position correspondence of treating according to workpiece on the said bushing plate is installed drill bushing.

It is further characterized in that: the tight device of said work piece positioning comprises alignment pin, gripper shoe and locking pliers; Said alignment pin and gripper shoe are fixed in the workpiece locating surface of said fixed head; The position of said alignment pin is provided with according to workpiece design basis position, and said locking pliers is fixed on the clamping workpiece face of said fixed head through cushion block; Said drill bushing is fixed in said bushing plate through the drill bushing screw; The lower surface of said bushing plate is also installed the workpiece alignment pin.

After adopting boring grab of the present invention, its beneficial effect is: its alignment pin location workpiece through the tight device of work piece positioning, and through locking pliers with Work-sheet pressing on gripper shoe, guaranteed workpiece reliable localization and clamping; The bushing plate that drill bushing is installed simultaneously is connected with the upper end of workpiece location-plate through hinge, and the folding of bushing plate is easy to operate, effectively reduces labor strength, enhances productivity; And the position of drill bushing is provided with according to the position of workpiece design boring or tapping, can further guarantee to hole or the precision of tapping position, thereby further guarantee the machining accuracy of workpiece; And the bushing plate bottom surface also is equipped with the workpiece alignment pin, can further guarantee the reliable location of workpiece, guarantees machining accuracy.
