Description

Technical Field

[0001] This utility model relates to the technical field of drilling and positioning devices for castings such as wind turbine hubs and frames, specifically a rapid positioning and drilling device for processing large wind turbine castings. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current (AC). A wind turbine typically consists of components such as a rotor, generator, deflector, tower, speed limiting safety mechanism, and energy storage device. However, special parts of the cast components, such as the hub and frame, often require marking and drilling.

[0003] However, marking and drilling are time-consuming and labor-intensive, so we continued to develop a device to quickly position and drill holes in the castings of wind turbine hubs and frames. Utility Model Content

[0004] This utility model provides a rapid positioning and drilling device for processing large wind turbine castings, in order to solve the problem of time-consuming and labor-intensive traditional scribing and drilling of wind turbine casting hubs and frames mentioned in the background art.

[0005] To address the existing problems, this utility model provides a rapid positioning and drilling device for processing large wind turbine castings, including a positioning plate. The positioning plate has a weight-reducing hole in its center, and a reinforcing rib is provided inside the weight-reducing hole. The two ends of the reinforcing rib are fixedly connected to the positioning plate, and handles are symmetrically connected to the reinforcing rib. Four hinge bolts are rotatably connected to the positioning plate in the circumferential direction, and vertical drill sleeves are connected between adjacent hinge bolts and on the positioning plate.

[0006] Furthermore, the adjacent hinge bolts are at a 90° angle, and the positioning plate has a first through hole for installing the hinge bolts.

[0007] Furthermore, a second through hole is provided on the positioning plate for installing a vertical drill sleeve.

[0008] Furthermore, a ring of protrusions is provided on the bottom surface of the positioning disk, the inner diameter of the protrusions is the same as the diameter of the weight reduction hole, and the outer edge of the protrusions is chamfered.

[0009] Furthermore, the positioning disc, reinforcing ribs, and handle are made of aluminum.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This large wind turbine casting machining quick positioning and drilling device can be used to first connect the entire device to the bolt holes on the wind turbine casting hub or frame using reamed bolts. Then, the operator only needs to hold an electric drill and insert the drill bit into the vertical drill sleeve to drill holes, which solves the problem of time-consuming and labor-intensive traditional marking and drilling.

[0012] 2. The rapid positioning and drilling device for machining large wind turbine castings has a first and second through hole on the positioning plate that are precisely pre-drilled according to the design. Therefore, after fixing the entire device to the hub or frame of the wind turbine casting by the reamer bolt in the first through hole, the operator only needs to use an electric drill to drill holes in the vertical drill sleeve. This device is more accurate than traditional scribing and drilling. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4A rapid positioning and drilling device for processing large wind turbine castings includes a positioning plate 1. A weight reduction hole 2 is opened in the center of the positioning plate 1. A reinforcing rib 3 is provided inside the weight reduction hole 2. The two ends of the reinforcing rib 3 are fixedly connected to the positioning plate 1. A handle 4 is symmetrically connected to the reinforcing rib 3. Four hinge bolts 5 are rotatably connected to the positioning plate 1 along the circumference. A vertical drill sleeve 6 is connected between adjacent hinge bolts 5 and on the positioning plate 1.

[0020] The adjacent hinge bolts 5 are at a 90° angle to each other, and the positioning plate 1 has a first through hole 7 for installing the hinge bolts 5.

[0021] The positioning plate 1 has a second through hole 8 for installing the vertical drill sleeve 6.

[0022] The positioning disk 1 has a raised ring 9 on its bottom surface. The inner diameter of the raised ring 9 is the same as the diameter of the weight reduction hole 2, and the outer edge of the raised ring 9 has a chamfer 10. By setting the raised ring 9, it can engage with the inner ring of the wind turbine casting hub or frame, preventing the positioning disk 1 from shifting. The chamfer 10 can reduce the frictional resistance when engaging with the inner ring of the casting.

[0023] Among them, the positioning disc 1, reinforcing rib 3, and handle 4 are made of aluminum.

[0024] It should be noted that the positioning plate 1, reinforcing rib 3, and handle 4 are made of aluminum to reduce weight and the burden on workers during movement and installation.

[0025] Working principle: When using, first hold the handle 4 with both hands and engage the protrusion 9 with the inner ring of the generator casting hub or frame. Then, thread the four hinge bolts 5 to the bolt holes of the wind turbine casting hub or frame. Then, the operator can use an electric drill to insert the drill bit into the vertical drill sleeve 6 to drill holes in the wind turbine casting hub or frame.
