[0013] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0014] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.

[0015] As Figure 1 shown, a lathe fixture for processing bar materials provided by the present utility model includes a base 1, a first clamping member 2, a nut 3, a spring 4, and a guiding screw 5.

[0016] One side above the base 1 is connected with a telescopic rod 6. The telescopic rod 6 includes a sleeve 6.1, a support rod 6.2 is inserted into the sleeve 6.1, and the first clamping member 2 is hinged to the upper side of the support rod 6.2. The height of the first clamping member 2 away from the clamping section can be adjusted through the telescopic rod 6. When the first clamping member 2 moves downward, the support rod 6.2 also correspondingly retracts into the sleeve 6.1.

[0017] A locking member 6.3 is connected to the sleeve 6.1. The locking member 6.3 is used to lock the support rod 6.2. In this embodiment, the locking member 6.3 is a locking bolt. A threaded through hole is provided in the sleeve 6.1, and the locking bolt is threadedly connected in the threaded through hole. The support rod 6.2 is locked by the locking bolt. After the first clamping member 2 is locked and fixed, then the locking member 6.3 is tightened for double-axis locking to prevent the second clamping member 2 from moving.

[0018] As Figure 2 shown, on the other side above the base 1, a sliding groove 7 is provided. The cross-section of the sliding groove 7 is convex. Two sliding blocks 8 with corresponding shapes are slidably connected to each other in the sliding groove 7. A bearing seat is connected to one side in the sliding groove 7, and a rotating bidirectional screw 7.1 is inserted into the bearing seat. A threaded through hole is provided on each sliding block 8, and the bidirectional screw 7.1 is threadedly connected in the threaded through hole. A through hole is provided on the other side in the sliding groove 7, and the bidirectional screw 7.1 passes through the through hole. A rotating plate 7.2 is connected to the outer end of the bidirectional screw 7.1. The rotating plate 7.2 is driven to rotate the bidirectional screw 7.1. The bidirectional screw 7.1 drives the two sliding blocks 8 by screw transmission, and the two sliding blocks 8 move relative to each other.

[0019] A support plate 9 is hinged to each sliding block 8, and a second clamping member 10 is hinged between the two support plates 9. The second clamping member 10 is an arc-shaped plate, and the arc-shaped plate is located below the clamping section of the first clamping member 2. When the two sliding blocks 8 move relative to each other, the second clamping member 10 is driven to move up and down. When clamping the bar stock, first, the distance between the first clamping member 2 and the second clamping member 10 is adjusted according to the diameter of the bar stock, so that the first clamping member 2 and the second clamping member 10 can clamp more bar stocks of different sizes, improving the adaptability of the device.
