DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1In this embodiment, a CNC positioning device for processing mold parts includes a base 1, the upper surface of the base 1 is rotatably connected to a support column 2 through a bearing, a mounting plate 3 is fixed to the upper surface of the support column 2, a bidirectional screw 4 is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the mounting plate 3 through a bearing, and two connecting rods 5 are threadedly connected to the outer surface of the bidirectional screw 4. The upper surface of the connecting rod 5 passes through the mounting plate 3 and extends to the upper side of the mounting plate 3 and is provided with a clamping mechanism 6 for clamping mold parts of different shapes, and the outer surface of the support column 2 is provided with an adjustment mechanism 7 for facilitating the adjustment of the angle of the mold parts.

[0024] Among them, the two connecting rods 5 are symmetrically distributed at the left and right ends of the vertical center axis of the bidirectional screw 4. The left side of the bidirectional screw 4 penetrates the mounting plate 3 and extends to the left side of the mounting plate 3 and is fixed with a hand wheel.

[0025] In this embodiment, a limit strip is fixed to the inner bottom wall of the mounting plate 3, and the bottom of the connecting rod 5 makes horizontal linear motion in the inner cavity of the limit strip. A fixing hole begins to be formed on the upper surface of the mounting plate 3, and the inner diameter of the fixing hole is adapted to the outer diameter of the connecting rod 5.

[0026] It can be understood that the mold parts are placed on the upper surface of the mounting plate 3, and then the hand wheel is turned to rotate the bidirectional screw 4. The rotation of the bidirectional screw 4 causes the two connecting rods 5 to move relative to each other. At this time, the two connecting rods 5 move in the inner cavity of the limit strip, and the movement of the connecting rods 5 can be limited.

[0027] See also Figure 2-3 In order to clamp and fix the mold parts of different regular shapes, the clamping mechanism 6 in this embodiment includes a fixed plate 601 fixed on the upper surface of the connecting rod 5. The movement of the connecting rod 5 drives the fixed plate 601 to move, so that the two fixed plates 601 can move relative to each other, and then the mold parts can be clamped. The inner walls of the opposite sides of the two fixed plates 601 are fixed with telescopic rods 602, and the outer surfaces of the telescopic rods 602 are movably sleeved with springs 603. The opposite sides of the telescopic rods 602 at the left and right ends are fixed with movable plates 604. The two ends of the spring 603 are relative to the movable plate 604 and the inner wall of the fixed plate 601. The two movable plates 604 are fixedly connected on one side, and extrusion blocks 605 are fixed on the opposite sides of the two movable plates 604. Sliding rods 606 are fixed on the upper and lower ends of the movable plate 604 on the opposite side of the fixed plate 601. The outer surface of the sliding rod 606 is slidably connected with a sliding sleeve 607. The side of the sliding sleeve 607 away from the sliding rod 606 is fixed to the inner wall of the fixed plate 601. The extrusion blocks 605 are in contact with the mold parts, and the spring 603 and the telescopic rod 602 can be squeezed by the extrusion of the mold parts. At this time, the sliding rod 606 slides in the inner cavity of the sliding sleeve 607, so that the mold parts can be stably clamped according to their shapes.

[0028] Among them, the number of telescopic rods 602 is several, and the telescopic rods 602 are evenly distributed on the inner wall of the opposite side of the two fixed plates 601. The opposite side of the two fixed plates 601 is provided with a through hole adapted to the size of the extrusion block 605. The shape of the sliding sleeve 607 is a cylinder with a hollow interior and a partially missing side facing the sliding rod 606. The sliding rod 606 and the sliding sleeve 607 are inseparable from each other.

[0029] See also Figure 4 In order to adjust the angle of the mold parts, the adjustment mechanism 7 in this embodiment includes a No. 1 gear 701 fixed on the outer surface of the support column 2, a protective box is fixed to the right end of the upper surface of the base 1, and a motor 702 is fixed to the inner bottom wall of the protective box. The output shaft of the motor 702 passes through the inner top wall of the protective box and extends to the upper side of the protective box and is fixed with a No. 2 gear 703. The No. 1 gear 701 is meshed and connected with the No. 2 gear 703. When the motor 702 is started, the output shaft of the motor 702 rotates, thereby driving the No. 2 gear 703 to rotate. The rotation of the No. 2 gear 703 drives the rotation of the No. 1 gear 701, and the rotation of the No. 1 gear 701 drives the support column 2 to rotate.

[0030] Among them, pulleys are fixed on the left and right ends of the lower surface of the support column 2, and a circular groove is opened on the upper surface of the base 1. The two pulleys make horizontal circular motion in the inner cavity of the circular groove. The two pulleys are symmetrically distributed on the left and right ends of the vertical central axis of the support column 2.

[0031] It can be understood that the rotation of the support column 2 drives the two pulleys to rotate in the inner cavity of the circular groove, the rotation of the support column 2 drives the mounting plate 3 to rotate, and the rotation of the mounting plate 3 can drive the mold parts to rotate, thereby facilitating the adjustment of the angle of the mold parts.

[0032] The working principle of the above embodiment is:

[0033] (1) When processing the mold parts, first place the mold parts on the upper surface of the mounting plate 3, and then turn the hand wheel to rotate the bidirectional screw 4. The rotation of the bidirectional screw 4 causes the two connecting rods 5 to move relative to each other. At this time, the two connecting rods 5 move in the inner cavity of the limit bar, which can limit the movement of the connecting rods 5. The movement of the connecting rods 5 drives the fixed plate 601 to move, so that the two fixed plates 601 can move relative to each other, and then the mold parts can be clamped. At this time, the extrusion block 605 contacts the mold parts, and the spring 603 and the telescopic rod 602 can be squeezed by the extrusion of the mold parts. At this time, the sliding rod 606 slides in the inner cavity of the sliding sleeve 607, so that the mold parts can be stably clamped according to their shape.

[0034] (2) When the angle of the mold part needs to be adjusted, the motor 702 is started, and the output shaft of the motor 702 rotates, thereby driving the second gear 703 to rotate. The rotation of the second gear 703 drives the rotation of the first gear 701. The rotation of the first gear 701 drives the support column 2 to rotate. The rotation of the support column 2 drives the two pulleys to rotate in the inner cavity of the circular groove. The rotation of the support column 2 drives the mounting plate 3 to rotate. The rotation of the mounting plate 3 can drive the mold part to rotate, thereby facilitating the adjustment of the angle of the mold part.
