Description
Technical Field
The utility model relates to the technical field of ball screw processing, in particular to a device for processing a central hole of a ball screw in a double-rotation mode.
Background
The ball screw is generally formed by rolling in batches, the thread part of the ball screw is in the size of a finished product, the thread part is used as a reference during machining, a center hole of the ball screw needs to be machined firstly, and then the shaft end is machined by using the center hole as the reference, so that the requirement on the precision of the center hole is high, and the requirement on the coaxiality is within 0.02 mm.
The center hole is machined on a common vehicle, a center drill is clamped by a fixed tailstock of the common vehicle to machine the center hole of the ball screw, and due to the fact that the precision of the common vehicle is not high, coaxiality of the center hole and the outer diameter of the screw is difficult to guarantee, and influence is brought to machining of a subsequent shaft end.
SUMMERY OF THE UTILITY MODEL
In order to effectively solve the problems in the background art, the utility model provides a device for processing a central hole of a ball screw in a double-rotation mode.
The specific technical scheme is as follows;
the utility model provides a two rotary machining ball centre bore devices, includes lathe bed, headstock and chuck, its characterized in that: a tailstock bottom plate is installed on one side of the lathe bed, a linear slide rail is installed on the upper portion of the tailstock bottom plate, a linear slide block is connected onto the linear slide rail in a sliding mode, a power head connecting plate is fixed to the upper portion of the linear slide block, a nut is installed in the center of the lower portion of the power head connecting plate and is in threaded connection with a lead screw, two ends of the lead screw are connected with the tailstock bottom plate through a lead screw fixed end supporting seat and a lead screw free end supporting seat respectively, and a hexagonal wrench position is arranged at the end portion of the lead screw; the power head is installed on the upper portion of the power head connecting plate, a central drill is installed at the output end of the power head, and the axis of the central drill and the axis of the chuck are on the same axis.
Preferably, the lathe bed, the spindle box and the chuck are all of the original structure of a common lathe.
Preferably, the tailstock base plate is adjustable in height.
Compared with the prior art, the utility model has the beneficial effects that: the method for machining the central hole by double rotation thoroughly solves the problem that the central hole of the ball screw is low in precision, is easy to realize and can be realized by basic transformation of a common vehicle, and the coaxiality of the central hole and the outer diameter of the ball screw can reach within 0.02 mm.

Detailed Description
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may also be oriented 90 degrees or at other orientations and the spatially relative descriptors used herein interpreted accordingly.
The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1-2, a double-rotation ball screw center hole machining device is mainly used for machining a center hole of a ball screw; the device comprises a center drill 1, a power head 2, a power head connecting plate 3, a linear slider 4, a nut 5, a lead screw fixed end supporting seat 6, a lead screw 7, a linear slide rail 8, an original tail seat bottom plate 9 and a lead screw free end supporting seat 10. The lathe bed 11, the spindle box 12 and the chuck 13 are original parts of a common lathe, and the power part is formed by reforming an original tail seat of the common lathe. Linear slide 8, lead screw stiff end supporting seat 7, lead screw free end supporting seat 10 are all installed on former tailboard bottom plate 9, and lead screw 7 is supported by two supporting seats, and nut 5 installs on unit head connecting plate 3, and unit head connecting plate 3 installs on 4 linear slider 4, and unit head 2 installs on unit head connecting plate 3, is equipped with central brill 1 on the unit head.
During machining, the workpiece 14 and the central drill 1 rotate simultaneously, the direction of rotation is opposite, the end part of the screw rod is provided with a hexagonal wrench position, the screw rod is rotated by the wrench, and the screw rod drives the nut to feed so as to machine the workpiece.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
