Abstract
The invention discloses a double-centre outer circle machining tool. The double-centre outer circle machining tool comprises a front centre and a rear centre arranged at the two ends of a workpiece respectively; and the front centre is provided with a transmission pin shaft used for transmitting torque. The double-centre outer circle machining tool has the beneficial effects that the structure is simple, clamping efficiency is high, manufacturing cost is low, the whole length of the workpiece can be machined at a time, and the using range is wide.
Description
Technical field
The present invention relates to clamping tool for machine work, particularly relate to a kind of Double Tops point processing tool for excircle.
Background technology
Processing tool for excircle mainly contains traditional Double Tops point processing tool and the top processing tool of hydraulic-driven two kinds, wherein traditional Double Tops point processing tool is top before adopting and back centre coordinates clamping work pieces, is used for transmitting torque drives workpiece to rotate at workpiece heart carrier on the cover of front top one end.Install after heart carrier and can cause interference to processing, processing work total length to have to the clamping at twice that turns around, both lost time, and have impact on again location of workpiece precision, when the part that Working position required precision is higher, can cause defectively even directly scrapping.Although hydraulic-driven is top achieve time processing total length, workpiece positional precision also higher, transmitting torque needs dependence to pull out pin to embed workpiece end face, and workpiece end face can be damaged; Top is hydraulic-driven, and cost is higher, and especially pressure is comparatively large, is not suitable for the processing of thin axle; Being not suitable for processing single-piece and parts in small batch, can not using on economical lathe and engine lathe, there is limitation in the scope of application.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provide that a kind of structure is simple, low cost of manufacture, can disposable processing work total length, Double Tops point processing tool for excircle that the scope of application is wide.
For solving the problems of the technologies described above, the present invention by the following technical solutions: a kind of Double Tops point processing tool for excircle, comprises the front top and back centre being divided into workpiece two ends, the described front top gear pin be provided with for transmitting torque.
Further improvement as technique scheme:
Described front top on offer installing hole, described gear pin is inserted in described installing hole.
Described front top comprise be connected successively the first top tip part, the first clamping portion and the first shank, described installing hole is opened in the first clamping portion.
Described first clamping portion is cylindrical clamping portion, and described first shank is tapered shank.
Described back centre comprises the second connected successively top tip part, the second clamping portion and the second shank.
Described second clamping portion is cylindrical clamping portion, and described second shank is tapered shank.
Compared with prior art, the invention has the advantages that: Double Tops point processing tool for excircle disclosed by the invention, the top gear pin be provided with for transmitting torque before it, on workpiece, correspondence arranges pin shaft hole and namely drives workpiece rotation by gear pin, and the clamping time is short, efficiency is high; Avoid and interference is caused to processing, can disposable processing work total length; Avoid and damage is caused to workpiece end face; And structure is simple, low cost of manufacture, can be widely used in numerically controlled lathe, engine lathe and grinding machine.
Further, front top on offer installing hole, gear pin is inserted in installing hole, is convenient to the dismounting of gear pin, maintenance.
