[0017] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0018] like Figure 1 and 2As shown, the blade blunt trailing edge demoulding and placement positioning tooling in this embodiment includes a hanging bracket, on which a mounting platform 2 is provided, and a vacuum pump 3 and a program central control device 4 are provided on the mounting platform 2. The hanging bracket includes two mutually parallel horizontal beams 11, and a plurality of groups of horizontal longitudinal beams 12 fixedly connected to the horizontal beams 11, and the horizontal longitudinal beams 12 are arranged parallel between the horizontal beams 11; the top surface of the hanging bracket is also provided with a hanging ring 13.

[0019] Four vertical downward support mechanisms are evenly arranged on both sides of the hanging bracket, which are connected to the vacuum pump 3. Three adsorption components for adsorbing blades are arranged on the hanging bracket, each of which includes a telescopic hanging arm vertically fixed below the hanging bracket, and a suction cup 5 is arranged at the bottom of each telescopic hanging arm; and a direction adjustment mechanism for adjusting the direction of the adsorption surface of the suction cup. The suction cup 5 is connected to the vacuum pump 3 through a pipeline (not shown in the figure), and a vacuum pressure loss alarm device (not shown in the figure) is arranged on the pipeline. The direction adjustment mechanism is connected to the program central control device 4.

[0020] In this embodiment, the supporting mechanism is a first vertical hydraulic cylinder 15, the cylinder body of the first vertical hydraulic cylinder 15 is fixed to the horizontal beam 11 of the hoisting bracket through a fixing plate 14, and a supporting pad is provided at the free end of the piston of the first vertical hydraulic cylinder 15. When in operation, the first vertical hydraulic cylinder will be supported on the supporting positioning columns on both sides of the mold edge of the blunt trailing edge on the main mold of the blade. The first vertical hydraulic cylinder is formed by combining a large stroke and a large load electric cylinder, which can meet the weight of the vacuum gripping load of the suction cup and the deadweight load of the adjustment mechanism.

[0021] The telescopic vertical arm is a second vertical hydraulic cylinder 7, the cylinder body of the second vertical hydraulic cylinder 7 is fixed on the horizontal longitudinal beam 12, and the suction cup 5 is connected to the telescopic rod of the second vertical hydraulic cylinder 7 through a universal shaft head 51 and a tilting shaft 65. In addition, adjacent second vertical hydraulic cylinders 7 are connected by horizontal reinforcing ribs 10 to prevent shaking during up and down lifting and ensure stability during adsorption.

[0022] An extension fixing rod 8 is also vertically downwardly provided on the lifting bracket, and the adjustment mechanism is fixed on the extension fixing rod 8. The extension fixing rod 8 in this embodiment adopts a 45# steel square tube structure, which can bear the deadweight of the adjustment mechanism and the bending force during the flipping operation, and ensure the stable realization of the flipping. Specifically, each group of the adjustment mechanism includes a motor 6, a driving gear 61, a double-sided rack 62, and a driven gear 64. The driving gear 61 is fixedly connected to the rotating shaft of the motor 6, and the driven gear 64 is linked to the universal shaft head 51 through the flip shaft 65, and the double-sided rack 62 is meshed with the driving gear 61 and the driven gear 64. The motor 6 drives the driving gear 61 to rotate, and the driving gear 61 drives the double-sided rack 62 to move up and down, thereby driving the driven gear 64 to rotate, and then drives the universal shaft 51 and the suction cup 5 to rotate to adjust the angle. The adjustment mechanism also includes a double-sided rack positioning frame 63, which is fixedly connected to the extended fixed rod 8, and the double-sided rack 62 is vertically inserted into the double-sided rack positioning frame 63, thereby preventing the double-sided rack 62 from shaking in the circumferential direction. In addition, the top and bottom of the double-sided rack 62 are provided with limit covers, and the outer contour size of the limit cover is larger than the inner diameter of the double-sided rack positioning frame 63, thereby preventing the double-sided rack 62 from falling off from the double-sided rack positioning frame 63. In addition, the motor 6 is connected to the program central control device 4.

[0023] Taking the demoulding operation as an example, the working method of demoulding the blunt trailing edge of the blade and laying the positioning tooling is described, including the following steps:

[0024] (1) The blunt trailing edge of the blade is demoulded and the placement and positioning tooling is transported to the designated area by means of a crane and a lifting ring 13;

[0025] (2) The blade blunt trailing edge demoulding and placement positioning tooling is set up on the mold, and the telescopic height of the corresponding first vertical hydraulic cylinder is controlled by the program central control device 4 to adjust the tooling to a suitable height position;

[0026] (3) The program control device 4 adjusts each suction cup to an angle that matches the surface contour of the blade through the adjustment mechanism;

[0027] (4) Start the vacuum pump 3 to absorb and grab the corresponding blade;

[0028] (5) After lifting, complete the corresponding work requirements and remove the tooling;

[0029] (6) After completing the above work procedures, the tooling is hoisted to the designated work area, and the first vertical hydraulic cylinder is lowered to complete the demoulding operation.

[0030] The program control device 4 of this embodiment is responsible for the program editing and motion control of the mechanical and electrical actions of the entire positioning tooling. In addition, the program control device 4 also has the ability to write and call out program parameters. When changing different blade types and different work requirements (positioning or grabbing), the program control device will automatically adjust the height and length of each supporting telescopic foot according to the corresponding process requirements and the size change of the blade mold, eliminating the inconvenience of traditional manual adjustment interference and the reduction of operation risks. The program control device can use mature products available on the market, which will not be described in detail here.

[0031] The blade blunt-end edge demoulding and placement positioning tooling in this embodiment can adapt to the height difference between the two sides of any mold, and can also ensure the horizontal grasping of the blade in areas with different height differences. The blade grasping angle can be adjusted through the direction adjustment mechanism, which can achieve effective vacuum adsorption of surfaces with any inclined angle. In addition, the independent telescopic function of the telescopic vertical arm can adapt to various scenes such as the height, concave and convex of the blade surface, ensuring that the blade remains in its original shape during grasping, avoiding damage to the surface of the object due to forced grasping. At the same time, the positioning tooling reduces labor demand and reduces labor costs.

[0032] The technical solutions in this embodiment are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.
