Abstract
The utility model discloses a tool bar, which belongs to the field of metal machine tool parts. The center of gravity of the conventional tool bar can easily shift. The tool bar comprises a tool bar body, a connecting sleeve and an outer sleeve, the center of the tool bar body is provided with an axial central hole, the head of the tool bar body is provided with a mounting part, which is provided with mounting holes, the connecting sleeve is fixedly mounted on the mounting part, the outer sleeve is sleeved on the periphery of the connecting sleeve, the tool bar body, the connecting sleeve and the outer sleeve are fixed by set screws in the mounting holes, a groove is arranged between the connecting sleeve and the outer sleeve, and balancing blocks are arranged in the groove. Since the connecting sleeve and the outer sleeve are added on the head of the tool bar, the weight of the tool bar is balanced, moreover, by changing different balancing blocks, the tool bar can be adapted to different tools for machining, and thereby the working efficiency is increased.
Description
Technical field
The utility model belongs to metal machine tool element device field, and is especially relevant with a kind of knife bar of machining tool use.
Background technology
The tradition knife bar is in process, knife bar is in the state of High Rotation Speed, the knife bar surface is owing to be in for a long time the centre-of gravity shift that the impact of high temperature causes, usually make knife bar produce the phenomenon of pendulum shake because the weight of knife rod head is uneven, thereby cause the workpiece processing tool rough surface, also might cause cutter in phenomenons such as process fracture, life-span of cutter has been produced seriously influence, affect efficient and the progress of work.
The utility model content
The purpose of this utility model is exactly will solve existing knife bar to have the defective that centre-of gravity shift occurs easily, and a kind of knife bar of easy control knife bar weight balancing is provided.
For this reason, the utility model is by the following technical solutions: a kind of knife bar, comprise the knife bar body, the center of knife bar body is provided with axial center hole, it is characterized in that, described knife bar also comprises adapter sleeve and overcoat, the head of described knife bar body is provided with installation portion, installation portion is provided with installing hole, and adapter sleeve is fixedly installed on the installation portion, and coat suit is in the outer peripheral face of adapter sleeve, the knife bar body, adapter sleeve and overcoat are locked in installing hole by dog screw, be provided with groove between described adapter sleeve and the overcoat, be provided with balance weight in the groove, the need worker that adds that can adapt to different cutters by the weight of changing balance weight asks.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described balance weight is ball, and the need worker that adds that can adapt to different cutters by the weight of changing ball asks.
Described adapter sleeve is provided with caulking groove, and gasket sleeve places caulking groove.
Use the utility model can reach following beneficial effect: the utility model is by increasing adapter sleeve and overcoat at knife rod head, realized the balance of knife bar weight, and pass through to change the processing that different balance weights can adapt to different cutters, improved the efficient of work.
