Description
Technical field
The utility model relates to machining apparatus field, in particular to a kind of double end turning lathe chuck.
Background technique
Double end turning lathe is one of the most widely used a kind of lathe in machine-building and assembling factory, with traditional vehicle
The difference of bed is to carry out product turnery processing, raising production efficiency, for as this both ends of vehicle bridge to workpiece both sides simultaneously
Concentricity more demanding long bar or pipe part, are processed with center lathe or numerically controlled lathe and are difficult to ensure its quality.Together
When for long shaft-like workpiece, in the installation of upper lathe due to lathe-head to be passed through, so workpiece installation is always very inconvenient,
Workpiece and lathe-head frictional force are larger, it is more difficult to push into lathe, and the cargo handling process of workpiece and head of a bed internal friction are easy
Workpiece is scratched, workpiece surface quality is influenced.
Summary of the invention
In order to make up for the defects of the prior art, the utility model provides a kind of double-end vehicles with the smooth workpiece loading and unloading of pulley
Bed uses chuck.
Utility model content
A kind of double end turning lathe chuck, including matrix, are uniformly provided with four claws in described matrix, each claw it
Between in 90 ° of distributions, described matrix is equipped with through-hole, and the through-hole edge is uniformly provided with four pulleys, each pulley and card
Pawl distributes alternately, and is distributed in 45° angle between each pulley and adjacent two claw.
Each pulley is made of two and half " convex " font modules and an idler wheel, is equipped with one in each module
The mounting hole of a ellipse, each module are both connected on matrix, and the idler wheel is set between two modules, outside the idler wheel
It extends in through-hole.
The utility model has the beneficial effects that：
The sliding friction for the process that workpiece is pushed into double end turning lathe can be become into rolling friction using the utility model, reduced
Frictional force during work-handling reduces the abrasion of workpiece surface, improves workpiece surface quality, facilitates the handling of workpiece,
It improves work efficiency.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view；
Fig. 2 is the utility model overlooking structure diagram.
In figure, 1 matrix, 2 claws, 3 through-holes, 5 pulleys, 51 modules, 52 idler wheels, 53 mounting holes.
Specific embodiment
Attached drawing is specific embodiment of the utility model.As shown in Figure 1 to Figure 2, a kind of double end turning lathe chuck, including base
Body 1, is uniformly provided with four claws 2 on matrix 1, and in 90 ° of distributions between each claw 2, matrix 1 is equipped with through-hole 3,3 side of through-hole
Along four pulleys 5 are uniformly provided with, each pulley 5 distributes alternately with claw 2, and is between each pulley 5 and adjacent two claw 2
45° angle distribution.Each pulley 5 is made of two and half " convex " font modules 51 and an idler wheel 52, is equipped in each module 51
One oval mounting hole 53, each module 51 are both connected on matrix 1, and idler wheel 52 is set between two modules 51, idler wheel 52
It extends in through-hole 3 outside.
Since long-shaft type workpiece is in two head of a bed for adding man-hour requirement to pass through double end turning lathe, so to be arranged on matrix 1 logical
Hole 3 can be convenient work-handling using this utility model, and claw 2 is driven using turbine and worm, is set in the module 51 on pulley 5
The mounting hole 53 set is ellipse, can according to circumstances adjust the installation site of pulley 5, and pulley 5 is to pass through installation by two
The screw in hole 53 is mounted on matrix 1, and the corresponding position on matrix 1 is equipped with threaded hole.
In addition to the technical characteristic described in the specification, remaining technical characteristic is technology known to those skilled in the art.
