Abstract
The utility model relates to the Z-axis balancing unit of a numerically-controlled boring and milling special machine tool, which comprises balance cylinders arranged at the top of the column of a boring and milling bed. The cylinder shafts of the balance cylinders are connected with a boring and milling power head through a cross slide bar. According to the utility model, the cylinder bodies of the balance cylinders are fixed to the top of the column, so that the height of the column is maximally and effectively reduced. The shafts of the oil cylinders are connected with the power head through a cross slide bar assembly. The cross slide bar assembly is provided to solve the problem that the movement directions of the cylinder shafts are not parallel to the Z-axis movement direction of the power head, thus is favorable to the transmission device of a ball screw. Meanwhile, the upward resultant force of the two balance oil cylinders approximately equals to the weight of the power head and the ball screw is not influenced by the weight of the power head. Therefore, the ball screw is long in service life, small in motion inertia and high in transmission sensitivity.
Description
Technical field
The utility model relates to a kind of numerical control boring and milling special purpose machine tool Z spindle balance device.
Background technology
It is insensitive that present boring and milling machine Z spindle balance device on the market is generally mechanical type balance response speed, and inertia can not be expired the high accuracy of servo-drive system, high-speed requirement more greatly.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide a kind of can satisfy servo-drive system high accuracy, the high-speed numerical control boring and milling special purpose machine tool Z spindle balance device that requires.
The technical scheme of the utility model employing is for this reason: comprise the compensating cylinder that is arranged on boring and milling machine column top, the cylinder axle of compensating cylinder is connected with the boring and milling unit head through cross slide bar.
The utility model has the advantages that: the utility model is fixed in the column top with the cylinder body of compensating cylinder; Maximization has effectively reduced the height of column; The oil cylinder axle is connected the oil cylinder axle through cross slide bar assembly with unit head; Cross slide bar assembly purpose is in order to solve the nonparallelism of the cylinder axle direction of motion and the unit head Z axle direction of motion, and is highly beneficial to ball screw.The approximate weight that equals unit head of making a concerted effort that two balancing cylinders make progress simultaneously, ball-screw does not receive the influence from the unit head own wt, so the life-span is long, and movement inertia is little, and transmission is highly sensitive.
Description of drawings
Fig. 1 is the structural representation of the utility model
1 is that compensating cylinder, 2 is that cylinder axle, 3 is that cross slide bar, 4 is the boring and milling unit head among the figure.
The specific embodiment
The utility model comprises the compensating cylinder 1 that is arranged on boring and milling machine column top, and the cylinder axle 2 of compensating cylinder 1 is connected with boring and milling unit head 4 through cross slide bar 3.
The compensating cylinder of the utility model provides a power that makes progress to boring and milling unit head 4 during work; The deadweight and other factor that overcome because of the boring and milling unit head produce the trend that moves downward; Make boring and milling unit head 4 can keep good balance quality, can not produce bigger vertical tremor; The compensating cylinder that is arranged so that of the cross slide bar 3 of the utility model can provide the power on the Z axle; Can not produce the component of other direction; Can make boring and milling unit head 4 all the time on a horizontal plane, guaranteed the boring and milling quality of workpiece, satisfy high accuracy, high-speed processing request; Simple in structure, have good practicality.
