Background
The tailstock is an important component of the numerical control lathe, and the axis of the tailstock and the axis of the spindle have strict coaxial requirements. When workpieces with different lengths are processed, the position of the tailstock on the guide rail needs to be adjusted, so that the locking mode between the tailstock and the guide rail is extremely important. The tailstock guide rail usually adopts a double-rectangular guide rail, the front surface (namely the top surface) of the rectangular guide rail is usually parallel to the main plane (namely the horizontal plane) of the machine tool, and the side surface is vertical to the main plane; the tailstock is arranged on the guide rail to form a guide rail pair. As shown in fig. 6-8, a slanted panel is usually disposed between the side surface of the guide rail and the tail seat for adjusting the gap between the side surface of the guide rail, and then the tail seat is pressed against the guide rail by a bolt. When the position of the tailstock needs to be adjusted, the bolt is slightly loosened, the tailstock is pushed or pulled to a proper position, and then the bolt is locked. After adjustment, the axis of the tailstock in the direction perpendicular to the main plane can not change greatly, because after locking, the tailstock is pressed on the front surface of the guide rail; however, the variation of the tailstock axis in the direction parallel to the main plane is greatly affected by the scraping quality of the gib and the size of the gap between the gib and the guide rail. Therefore, the axis of the tailstock after adjustment is in the main plane and is difficult to ensure to be strictly parallel to the axis of the main shaft.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a locking is effectual, improves tailstock axis and main shaft axis depth of parallelism's tailstock guide rail locking structure.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a tailstock guide rail locking structure, includes tailstock, guide rail seat, vertical locking Assembly and horizontal locking Assembly, be equipped with an at least guide rail on the guide rail seat, the tailstock erects on the guide rail, vertical locking Assembly vertically wears to establish in tailstock and guide rail seat, horizontal locking Assembly wears to establish the side of tailstock and guide rail, and the tailstock passes through vertical locking Assembly and horizontal locking Assembly locking connection with the guide rail, horizontal locking Assembly includes panel, housing screw and transfers the clearance screw, the panel is established between tailstock lateral wall and guide rail side, housing screw and transfer the clearance screw and violently pass tailstock lateral wall and panel threaded connection.
Preferably, the longitudinal locking assembly comprises a locking block and a locking bolt, the locking block is clamped on the guide rail seat, the locking bolt longitudinally penetrates through the tailstock, the locking block and the guide rail seat, and the locking bolt is rotated to lock and fix the tailstock and the guide rail.
Preferably, the cross-sectional shape of the guide rail is T-shaped, and the locking block abuts against the lower surface of the top of the guide rail.
Preferably, the top of the locking block is in a convex shape, and a threaded hole is formed in the locking block.
Preferably, a plurality of threaded holes are formed in the gib.
The beneficial effects of the utility model reside in that: eliminate the clearance between tailstock and the guide rail top surface and the clearance between horizontal locking Assembly elimination tailstock and the guide rail side through vertical locking Assembly for the tailstock locking is fixed on the guide rail, guarantees the tailstock axis and the parallel of lathe main shaft axis, reinforcing processing stability, improves the machining precision.
