It can only meet the clamping of workpieces of a single shape, but cannot meet the clamping use of workpieces of different shapes. It is not very versatile and has certain defects and shortcomings, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 and Figure 2As shown, a high-precision positioning turning device for a mold proposed in an embodiment of the utility model includes a mold main body 1, on which two symmetrically distributed track grooves 2 are opened, and the track grooves 2 of the mold main body 1 are slidably connected with sliding blocks 3, and the upper surface of the sliding blocks 3 is fixedly connected with a support rod 4, and a cross plate 5 is fixed on the top of the support rod 4, and symmetrically distributed screws 6 are threadedly connected on the cross plate 5, and a positioning tool 7 is fixed at one end of the screw 6, and the positioning tool 7 includes a fixed block 701 fixedly connected to one end of the screw 6, and an arc-shaped clamping plate 703 rotatably connected to a rotating seat 702 on one side of the fixed block 701, and a rotating shaft 704 is provided at the connection between the arc-shaped clamping plate 703 and the rotating seat 702, and the arc-shaped clamping plate 703 rotates around the rotating shaft 704 on the rotating seat 702 to achieve clamping of workpieces of different shapes.

[0018] It should be noted that, by opening two track grooves 2 on the mold body 1, the setting of the track grooves 2 can realize the sliding limit of the sliding block 3, so that the sliding block 3 drives the support rod 4 and the cross plate 5 to move, and by threading two screws 6 on the cross plate 5, the extension length of the positioning fixture 7 can be adjusted when the screw 6 rotates, which can meet the clamping needs of workpieces of different widths and shapes. By providing a rotatable arc-shaped clamping plate 703 on the positioning fixture 7, the arc-shaped clamping plate 703 rotates around the rotating shaft 704 on the rotating seat 702 to achieve the clamping of workpieces of different shapes. When the arc-shaped clamping plate 703 contacts the outer surface of the workpiece, it can rotate along the outer surface contour of the workpiece, so that the two ends of the arc-shaped clamping plate 703 are attached to the outer surface of the workpiece, thereby meeting the clamping needs of rectangular, circular, and special-shaped workpieces, and meeting the versatility of the device.

[0019] like Figure 1 As shown, in some embodiments, the other end of the screw rod 6 is fixedly connected to a handle 8.

[0020] It should be noted that the setting of the handle 8 is convenient for controlling the rotation of the screw rod 6, and then controlling the extension and retraction of the positioning fixtures 7, and adjusting the actual position of each positioning fixture 7 to meet the clamping requirements of workpieces of different shapes.

[0021] like Figure 1 and Figure 3 As shown, in some embodiments, the lower surface of the mold body 1 is fixedly connected to two symmetrically distributed supports 9, and a bidirectional screw rod 11 is rotatably connected between the two supports 9, the sliding block 3 is threadedly connected to the bidirectional screw rod 11, and one end of the bidirectional screw rod 11 extends to the outside of the support 9 and is fixed with a handwheel 10.

[0022] It should be noted that by fixing two supports 9 on the lower surface of the mold body 1 and rotating a bidirectional screw 11 between the two supports 9, the bidirectional screw 11 can control the telescopic movement of the sliding block 3 when it rotates, so that the sliding block 3 moves in the track groove 2 of the mold body 1, driving the support rod 4 and the cross plate 5 to move, thereby realizing the positioning and clamping of the workpiece.

[0023] like Figure 1 and Figure 3 As shown, in some embodiments, a support leg is axially fixed to the lower surface of the mold body 1, and a base is fixed to the lower end of the support leg to achieve the overall support function of the device.

[0024] The working principle and use steps of the utility model are as follows: when in use, the workpiece is placed on the mold body 1, and the bidirectional screw 11 is controlled to rotate by the hand wheel 10. When the bidirectional screw 11 rotates, it can drive the sliding block 3 to slide in the track groove 2 of the mold body 1, and drive the support rod 4, the cross plate 5, the screw 6, and the positioning tool 7 to move closer to the inside. The arc-shaped clamping plate 703 on the positioning tool 7 contacts the outer surface of the workpiece. When in contact, the arc-shaped clamping plate 703 itself can be adjusted in rotation angle according to the outer contour of the workpiece, so that the two ends of the arc-shaped clamping plate 703 are against the outer surface of the workpiece, and then meet the clamping of workpieces of different shapes. When facing clamping of different widths and shapes, the screw 6 can be rotated according to needs to make the corresponding positioning tool 7 retract, and the position of the positioning tool 7 is adjusted to meet the clamping of the workpiece of the corresponding shape, so as to carry out the turning process of the workpiece.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
