Description
Technical Field
The utility model relates to a lathe equipment, concretely relates to car boring double-purpose lathe tailstock.
Background
The machine tool often touches a workpiece needing to process an outer circle and a deep hole in the processing, the outer circle processing generally needs clamping and turning on a lathe, and the deep hole processing generally needs boring. Therefore, the workpiece needs to be moved between the lathe and the boring machine and processed respectively, which greatly affects the processing efficiency.
Disclosure of Invention
In order to solve the problem, the utility model provides a turning and boring double-purpose lathe tailstock realizes turning and boring on a lathe, improves machining efficiency, alleviates hand labor. The utility model adopts the technical scheme as follows:
a tailstock of a turning and boring dual-purpose machine tool comprises a chuck, a support, a core shaft and a boring rod, wherein the support is arranged on a machine tool guide rail in a sliding mode;
the mandrel is rotatably arranged in a transverse central hole of the support, and the chuck is fixedly connected to the front end of the mandrel;
the tail of the boring rod is connected with a feeding mechanism, the head of the boring rod is connected with a boring tool bit, the boring rod is in sliding fit with the transverse center hole of the mandrel, the boring tool bit is in sliding fit with the transverse center hole of the chuck, and the feeding mechanism drives the boring rod to axially slide along the mandrel so that the boring tool bit extends out of the chuck to bore a workpiece or retracts into the chuck.
According to the turning and boring double-purpose machine tool tailstock, a circle of balls for supporting the inner hole of the workpiece are mounted on the outer circle of the boring tool bit.
According to the turning and boring double-purpose machine tool tailstock, the supporting sleeve is rotatably arranged in the transverse center hole of the chuck, the outer circle of the boring tool bit is provided with the guide block, and the guide block is in sliding fit with or separated from the inner circle of the supporting sleeve.
The utility model has the advantages that: the tailstock has the function of a lathe tailstock, can clamp and support a workpiece, is used for turning the excircle, the end face and the like of the workpiece, and can also be used as a boring head of a deep hole boring machine for boring deep holes. Turning and boring are realized on one machine tool, and the production efficiency is greatly improved.

In the figure: 1 is a chuck, 2 is a support sleeve, 3 is a boring cutter head, 4 is a boring bar, 5 is a bearing, 6 is a mandrel, 7 is a support, 8 is a feeding mechanism, 9 is a jaw, 10 is a guide block, and 11 is a ball.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
A tailstock of a turning and boring double-purpose machine tool comprises a chuck 1, a support 7 arranged on a machine tool guide rail in a sliding mode, a mandrel 6 and a boring rod 4;
the mandrel 6 can be rotatably arranged in a transverse central hole of the support 7, and the chuck 1 is fixedly connected to the front end of the mandrel 6;
the tail of the boring rod 4 is connected with a feeding mechanism 8, the head of the boring rod 4 is connected with a boring cutter head 3, the boring rod 4 is in sliding fit with a transverse center hole of the mandrel 6, the boring cutter head 3 is in sliding fit with a transverse center hole of the chuck 1, and the feeding mechanism 8 drives the boring rod 4 to axially slide along the mandrel 6 so that the boring cutter head 3 extends out of the chuck 1 to bore a workpiece or retracts into the chuck 1.
In the turning and boring double-purpose machine tool tailstock, a circle of balls 11 for supporting the inner hole of the workpiece are arranged on the outer circle of the boring tool bit 3.
According to the turning and boring double-purpose machine tool tailstock, the supporting sleeve 2 is rotatably arranged in the transverse center hole of the chuck 1, the outer circle of the boring tool bit 3 is provided with the guide block 10, and the guide block 10 is in sliding fit with or separated from the inner circle of the supporting sleeve 2.
The utility model discloses car boring theory of operation does:
the assembly for boring and the arrangement for turning are mounted in a transverse central bore in the support 7. The chuck 1 supports the inner hole of the workpiece by using the clamping jaws 9, the chuck 1 rotates along with the mandrel 6 and the workpiece simultaneously, the outer ring of the bearing 5 rotates, the inner ring does not rotate, namely the boring cutter head 3 stands still in the support sleeve 2 at the moment, and turning is realized. Clamping the excircle of a workpiece by using a jaw 9, pushing a boring rod 4 to feed by using a feed mechanism 8, guiding the boring cutter head 3 in a support sleeve 2 by using a guide block 10 at first, separating the guide block 10 from the support sleeve 2 after a ball 11 slides to the inner hole of the workpiece, supporting and guiding the boring cutter head 3 by using the ball 11 at the moment, and finishing boring; the feed mechanism 8 then causes the boring bar 4 to retract into the support sleeve 2. Therefore, the processing of the excircle and the inner hole of the workpiece on one machine tool is realized, the efficiency is high, and the operation is convenient.
