Abstract
The utility model relates to a turning tool of a center wedge. The turning tool is characterized by comprising a bracket. The bracket comprises a vertical plate and a horizontal plate; the horizontal plate is connected with a locating block through a spindle; an axis of the spindle is vertical to the horizontal plate; a locating slot is formed in the locating block; and the locating slot is provided with a wedge-shaped locating surface; and the locating block is provided with a pressing mechanism which is used for pressing the center wedge tightly. The turning tool of the center wedge is convenient to use; clamping is finished at one time to process the upper face and the lower face of the wedge; and the processing efficiency and the processing precision are high.
Description
Technical field
The utility model belongs to the clamping tool for machine work technical field, particularly relates to a kind of pin drill hole tool of center wedge.
Background technology
Along with manufacturing development, division of labor specialization, large-scale mass production, product parts lightness, powder metallurgy maturing, high-quality a large amount production capacity power have become the inexorable trend of development, requirement to part processing and manufacturing fixture used is also more and more higher, and fixture is the important frock that guarantees Workpiece Machining Accuracy and production efficiency.Center wedge is a kind of cast member, following and the upper part of center wedge need to carry out respectively turning processing, and in conventional art, center wedge utilizes lathe chuck to be installed on lathe, at twice respectively to the top of center wedge and below carry out turning processing, so, need to just can complete processing to the center wedge operation of carrying out being installed for twice, working (machining) efficiency is low, in addition, be generally multi-jaw chuck on lathe, chuck fixed center voussoir is stable not, affects machining accuracy.
Summary of the invention
The utility model is intended to solve the machining accuracy that exists in known technology and the low technical problem of working (machining) efficiency and a kind of pin drill hole tool of easy to use, the center wedge that can improve workpiece working (machining) efficiency and machining accuracy is provided.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of turning tool of center wedge, comprise carriage, described carriage comprises riser and transverse slat, connect locating piece by rotating shaft on described transverse slat, the axis of described rotating shaft is vertical with described transverse slat, described locating piece is provided with locating slot, has the wedge shape locating surface in described locating slot, is equipped with on described locating piece for the hold-down mechanism that compresses center wedge.
The utility model can also adopt following technical scheme:
Described transverse slat is provided with elastic positioning pin, and the axis of described elastic positioning pin is vertical with described transverse slat.
Described hold-down mechanism comprises the stud that is connected with described locating piece, equipped pressing plate and nut on described stud.
Described pressing plate is the L shaped plate body.
Described rotating shaft is the threaded screw rod of two ends tool.
Transverse slat is provided with at least two described elastic positioning pins.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, namely design a kind of Special clamp tool with turning center voussoir end face, this frock by rotary location realize soon disposable be installed to the top of center wedge and below distinguish turning and processes, not only greatly accelerated the turning efficient of workpiece, and the clamping of frock is effective, stability is high, the machining accuracy that can improve center wedge.
