Description

Technical Field

[0001] This utility model relates to the field of turbine blade processing technology, and in particular to a positioning mechanism for wind turbine blade root end processing equipment. Background Technology

[0002] With the booming development of the wind power industry, the manufacturing process of wind turbine blades, as core power generation equipment, is becoming increasingly demanding. The root end of the wind turbine blade, as a key part connecting the blade and the hub, bears enormous stress and complex loads. Its machining accuracy and quality directly affect the overall performance and operational safety of the wind power generation equipment.

[0003] Early positioning mechanisms in wind turbine blade root processing equipment had many limitations. Firstly, in terms of processing dimensions, traditional equipment was often only suitable for relatively simple, limited-size blade roots. When faced with the diverse and larger processing needs of blade roots, it struggled to meet the industry's growing trend towards larger blades. For example, many existing devices could not directly process wind turbine blade roots with diameters exceeding 6 meters. Processing even larger sizes required extensive modifications to the entire equipment, or even replacing it entirely, resulting in high costs and significant time and effort.

[0004] On the other hand, during long-term operation, due to the structural design of the equipment itself, it is unable to effectively cope with the weight load of the processing center. The tower is prone to problems such as forward tilting due to uneven stress, which not only reduces the service life of the equipment, but also greatly increases the defect rate of processing, thus restricting the efficient and high-quality development of the wind power equipment manufacturing industry. Utility Model Content

[0005] The purpose of this invention is to provide a positioning mechanism for wind turbine blade root end processing equipment. By using this device, the above-mentioned problems can be solved.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a positioning mechanism for a wind turbine blade root end processing equipment, including a base and a tower base. A tower base is provided on the top of the base, a lateral moving component is provided at the bottom of the tower base, a rotary machining center is provided at the front end of the tower base, a vertical moving component is provided on one side of the rotary machining center, and an auxiliary guiding component is provided at the rear end of the tower base.

[0007] Preferably, the lateral movement component includes an X-direction slider fixed to the bottom of the tower base, the X-direction slider being slidably disposed on an X-direction guide rail, and the X-direction guide rail being fixed to the top of the base.

[0008] Preferably, the up-and-down moving component includes a motor mounted on one side of the rotary machining center, a gear fixed on the motor shaft, Y-direction guide rails fixed on both sides of the front end of the tower, a Y-direction slider slidably disposed on the outside of the Y-direction guide rails, the Y-direction slider being fixed to the rear end of the rotary machining center, and a rack disposed on one side of the front end of the tower, the rack being fixed to the front end of the tower and located on one side of the gear and meshing with it.

[0009] Preferably, the auxiliary guiding component includes a counterweight block disposed at the rear end of the tower base, a linear guide rail fixed to the front end of the counterweight block, a linear slider slidably disposed on the linear guide rail, a connecting block fixed to the front end of the linear slider, and the connecting block fixed to the rear end of the tower base.

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

[0011] 1. The positioning mechanism of the wind turbine blade root end processing equipment provided by this utility model has a base with a machine tool bed design, which can process the root of wind turbine blades with a diameter of up to 6 meters. If a larger size needs to be processed, it can be extended to 8 meters or more by adding a bed section, which improves the applicability of processing the root ends of blades of different specifications.

[0012] 2. The present invention provides a positioning mechanism for a wind turbine blade root end processing equipment. The tower is installed on the top of the base via an X-direction guide rail and an X-direction slider. The X-direction slider slides laterally outside the X-direction guide rail, enabling the tower to drive the rotary machining center to move horizontally to the required position, covering the entire processing length and meeting the processing needs of different positions. The rotary machining center uses a rack and pinion as a driving mechanism and is installed at the front end of the tower via a Y-direction guide rail and a Y-direction slider. The motor drives the gear to rotate and cooperate with the rack, enabling it to move up and down at the front end of the tower to the required position, covering the full height of the blade root, and realizing vertical positioning processing.

[0013] 3. The rear end of the tower base is connected to the linear guide rail at the front end of the counterweight via a linear slider. When the tower base moves laterally, the linear slider slides laterally outside the linear guide rail. The interaction between the linear guide rail and the linear slider guides the lateral movement of the tower base, improving its lateral stability. Simultaneously, when the rotary machining center moves vertically, the Y-direction slider slides on the Y-direction guide rail. The Y-direction guide rail and the Y-direction slider guide its vertical movement, improving its vertical stability. The tower base is connected to the counterweight, which provides counterweight to the base and tower base. This ensures the weight of the base, improving its own stability; it also prevents the front end of the tower base from tilting forward due to gravity when bearing the weight of the rotary machining center for extended periods, thus enhancing the overall stability of the positioning mechanism.

[0020] 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.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figures 1 to 5 As shown, the positioning mechanism of the wind turbine blade root end processing equipment of this utility model includes a base 1 and a tower 2. The tower 2 is provided on the top of the base 1, the horizontal moving component is provided on the bottom of the tower 2, the rotary machining center 3 is provided at the front end of the tower 2, the vertical moving component is provided on one side of the rotary machining center 3, and the auxiliary guiding component is provided at the rear end of the tower 2.

[0023] The lateral movement component includes an X-direction slider 41 fixed to the bottom of the tower base 2, the X-direction slider 41 being slidably mounted on an X-direction guide rail 4, and the X-direction guide rail 4 being fixed to the top of the base 1.

[0024] The up-and-down moving assembly includes a motor 5 mounted on one side of the rotary machining center 3. A gear 24 is fixed on the shaft of the motor 5. Y-direction guide rails 21 are fixed on both sides of the front end of the tower 2. A Y-direction slider 22 is slidably arranged on the outside of the Y-direction guide rails 21. The Y-direction slider 22 is fixed to the rear end of the rotary machining center 3. A rack 23 is arranged on one side of the front end of the tower 2. The rack 23 is fixed to the front end of the tower 2 and is located on one side of the gear 24 and meshes with it.

[0025] The auxiliary guide component includes a counterweight 6 disposed at the rear end of the tower base 2. A linear guide rail 7 is fixed to the front end of the counterweight 6. A linear slider 72 is slidably disposed on the linear guide rail 7. A connecting block 71 is fixed to the front end of the linear slider 72. The connecting block 71 is fixed to the rear end of the tower base 2.

[0026] Specifically, the base 1 is the machine tool bed, which can process the root of wind turbine blades with a maximum diameter of 6 meters. If a larger size needs to be processed, it can be extended to 8 meters or more by adding a bed section.

[0027] Tower 2 is a tower frame. In the horizontal direction, the tower frame moves along the machine tool bed to cover the entire machining length. In the vertical direction, the boom moves up and down at the front of the tower frame using rack 23 and gear 24 as the driving mechanism, thereby covering the full height of the blade root.

[0028] Furthermore, the tower 2 is mounted on the top of the base 1 via the X-direction guide rail 4 and the X-direction slider 41. By using the X-direction slider 41 to slide laterally on the outside of the X-direction guide rail 4, the tower 2 can move laterally on the top of the base 1, thereby driving the rotary machining center 3 to move laterally to the required position for machining.

[0029] The tower base 2 is connected to the linear guide rail 7 at the front end of the counterweight block 6 via a linear slider 72. When the tower base 2 moves laterally on the top of the base 1, it will drive the linear slider 72 to slide laterally outside the linear guide rail 7. The linear guide rail 7 and the linear slider 72 can guide the lateral movement of the tower base 2, thereby improving the stability of the lateral movement of the tower base 2. At the same time, the tower base 2 is connected to the counterweight block 6 via the linear slider 72. The weight of the counterweight block 6 can balance the weight of the base 1 and the tower base 2. This not only ensures the weight of the base 1 and improves its stability, but also improves the stability of the tower base 2. It also prevents the front end of the tower base 2 from tilting forward due to the weight of the rotary machining center 3 when it bears the weight of the rotary machining center 3 for a long time.

[0030] The rotary machining center 3 is mounted on the front end of the turret 2 via a Y-direction guide rail 21 and a Y-direction slider 22. A motor 5 drives a gear 24 to rotate, which, in conjunction with a rack 23, allows the rotary machining center 3 to move up and down at the front end of the turret 2 to the desired position for machining. During this up-and-down movement, the rotary machining center 3 causes the Y-direction slider 22 to slide along the Y-direction guide rail 21. The Y-direction guide rail 21 and the Y-direction slider 22 guide the up-and-down movement of the rotary machining center 3, improving its stability.
