As described in the background art, in the prior art, when some tubular castings are machined, long-stroke turning is carried out on a machine tool in a production workshop, and if the castings are machined under the condition that a proper clamp is not used for clamping the castings, the castings are seriously shaken in the machining process, so that the machining precision is influenced, the yield is reduced, and the damage to the lathe is large. Although some work holders assist in machining, the work holders are manually operated by workers to clamp or loosen during operation, so that the production efficiency is low, and the safety in use is not high.

To solve the technical problem, the utility model provides a tubular casting positioner for lathe, it includes base 100, is fixed in mounting fixture 300 and the driving source on the base 100, and can be relative mounting fixture 300 removes removal anchor clamps 200.

Specifically, referring to fig. 1-3, the fixing clamp 300 is an elongated baffle plate, and the top of the elongated baffle plate is fixed to the base 100 by a plurality of screws.

The movable clamp 200 includes an elongated vertical plate 210, a plurality of mounting bases 230 are convexly disposed on a lower end surface of the elongated vertical plate 210, each mounting base 230 is provided with a horizontal insertion rod 220, the plurality of insertion rods 220 are parallel to each other, and the elongated baffle is provided with a through hole 310 matched with the insertion rod 220. Arc positioning grooves matched with each other are arranged on the surfaces of the long vertical plates 210 opposite to the long baffle; the driving source is disposed on the other side of the long vertical plate 210 and is fixedly connected to the long vertical plate 210. For driving the elongated riser 210 close to the elongated baffle to clamp and secure the tubular casting. Therefore, the tubular casting to be fixed is placed between the fixing clamp 300 and the movable clamp 200, the movable clamp 200 is driven by the driving source to be close to the long baffle, so that the workpiece is clamped in the arc-shaped positioning groove, and the positioning of the workpiece can be realized.

Further, a step portion 320 is formed on the surface of the elongated baffle opposite to the elongated vertical plate 210, an elongated receiving groove 250 is formed between the step portion 320 and the elongated vertical plate 210, the arc-shaped positioning groove is disposed on the side surface of the step portion 320, and the receiving groove 250 is used for placing a tubular casting. Further, the bottom sides of the arc-shaped positioning grooves are flush with the bottom surface of the step part 320 or slightly higher than the bottom surface of the step part 320, so that in use, a workpiece is placed in the accommodating groove 250, and the driving source is started to clamp the workpiece, without manually holding the workpiece between the pair of arc-shaped positioning grooves.

In this embodiment, the height of the through hole 310 is flush with the height of the bottom surface of the step portion 320, and the long baffle is provided with an avoiding groove 330 matched with the mounting base 230, so that the long vertical plate 210 can be close to and closely attached to the side surface of the step portion 320, and a better fixing effect can be achieved for the tubular casting. Of course, the arc-shaped positioning slot is a semicircular positioning slot 240.

Furthermore, in order to prevent the workpiece from sliding, bump type anti-slip threads are arranged on the groove wall of the arc-shaped positioning groove to increase the friction force between the workpiece and the positioning groove.
