Abstract
The utility model discloses a positioning device of crankshaft lathe carriage, which comprises a fixed frame (5); a tool rest (4) and a leading screw (1); a V-shaped boss is disposed on the upper portion of the fixed frame (5); the tool rest (4) is provided with a groove matching with the shape of the V-shaped boss of the fixed frame (5). The leading screw (1) moves the tool rest (4) on the fixed frame (5) back and forth. A tapered iron (2) is also disposed in the groove; at least one screw hole is formed on one side of the tool rest (4); a screw (3) in a corresponding screw hole is fastened to screw up the screw hole to support the tapered iron (2) tightly. The device is applied in large-scale crankshaft machining enterprise.
Description
Technical field
The utility model relates to a kind of positioner of lathe saddle, relates in particular to a kind of positioner of crankshaft toothed wheel knife rest.
Background technology
The knife rest of the crankshaft toothed wheel that uses at present drives by little leading screw as fixed mount and tool rest, manual or motor-driven rotation realizes feed, because when the machining crankshafts end face, the amount of cutting is big and be interrupted cut, cause little leading screw drastic deformation, constantly make a concession, influence the precision and the surface roughness of machined surface to the direction that reduces load.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to operate, the positioner of the crankshaft toothed wheel knife rest that precision is high.
The technical solution of the utility model is: a kind of positioner of crankshaft toothed wheel knife rest, it comprises fixed mount 5, tool rest 4, leading screw, it is characterized in that: described fixed mount 5 tops are provided with the V-arrangement boss, described tool rest 4 is provided with and the suitable groove of described fixed mount 5V shape boss shape, described leading screw 1 moves before and after described tool rest 4 is on described fixed mount 5, also be provided with wedge 2 in the described groove, one side of described tool rest 4 is provided with at least one screw, and the trip bolt 3 described corresponding screw that is spirally connected holds out against wedge 2 in corresponding screw.
The technical solution of the utility model also has: described screw is three.
The beneficial effects of the utility model are: wedge 2 is set in the groove of described tool rest 4, and trip bolt 3 is set, eliminated the gap between boss and the groove, increased the stability of tool rest 4, improved the precision and the surface roughness of machined surface.
Description of drawings
Fig. 1 is a structure chart of the present utility model
Among the figure 1, leading screw 2, wedge 3, trip bolt 4, tool rest 5, fixed mount.
The specific embodiment
As Fig. 1 institute formula, the utility model relates to a kind of positioner of crankshaft toothed wheel knife rest, it comprises fixed mount 5, tool rest 4, leading screw, described fixed mount 5 tops are provided with the V-arrangement boss, described tool rest 4 is provided with and the suitable groove of described fixed mount 5V shape boss shape, described leading screw 1 moves before and after described tool rest 4 is on described fixed mount 5, thereby realize that lathe tool can move front and back on the tool rest 4 on fixed mount 5, guarantee that the amount of cutting reaches designing requirement, is provided with wedge 2 in described groove when the machining crankshafts end face, one side of described tool rest 4 is provided with three screws, the trip bolt 3 described corresponding screw that is spirally connected holds out against wedge 2 in corresponding screw, has eliminated the gap between boss and the groove, makes tool rest 4 and fixed mount 5 form one like this, improve the stability of processing, thereby guaranteed machining accuracy.
Claims (2)
