Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wind power blade processing, and in particular relates to a novel root end adjusting bracket used for a wind power blade drilling machine. Background Art
[0002] The root end of the composite blade of the wind turbine needs to be processed. The root end needs to be cut, ground and machined with axial and radial holes. During this process, the blade is placed in a support system, which consists of at least 3 separate brackets in specific positions. The first bracket is supported at the root end of the blade, which is circular on the outside. The blade manufacturer has very high tolerance requirements for root end machining. The difficulty lies in the fact that the root end of the blade is round, so the blade axis is required to be aligned with the axis of the drilling and milling equipment.
[0003] The composite material of the blade can withstand great stress, but it is flexible to a certain extent. The current problem is that when a large blade with a large root diameter is placed in the support system of the drilling machine, the blade tends to deform under its own weight. Therefore, the blade manufacturer uses a clamping device at the root end of the blade to keep the root end of the blade round, but they cannot find a measurement method that does not require time-consuming and expensive measurement. For example, laser trackers are very time-consuming and costly.
[0004] It is also important that the blade axis is aligned with the axis of the drilling and milling equipment because of the machining tolerance requirements of the blade. Generally speaking, the blade sizes are slightly different because manufacturers will purchase multiple sets of molds to produce the same blade. In order to align the root end with the drilling machine, the first bracket can be manually adjusted in height and left and right position, so that the root end of the blade can be moved in the x and y directions. In order to find the deviation between the blade axis and the axis of the drilling and milling equipment, the conventional method is to drill test holes with the same spacing on the root end surface of the blade. Then, the manufacturer's personnel measure the distance from the test holes to the outer wall of the root end. If the roundness of the test hole distribution is not within the given tolerance range, the height and left and right of the first bracket must be adjusted to change the position of the root end so that the blade is better aligned with the drilling and milling equipment. This alignment process is very time-consuming and involves many people and labor.
[0005] To this end, the applicant has previously provided a corresponding solution, which can be found in CN201821922892.0. However, as the root diameter of wind turbine blades becomes larger and larger, we find that the device can no longer meet the process requirements in terms of accuracy, so it is necessary to design a new type of adjustment bracket to solve the problem of insufficient accuracy so that the adjustment mechanism can perfectly meet the process requirements. Utility Model Content
[0006] The purpose of the utility model is to:
[0007] In order to solve the problem that the adjustment accuracy of the wind turbine blade root end processing bracket in the prior art cannot meet the process requirements of large-size blades, a new root end adjustment bracket for a wind turbine blade drilling machine is provided.
[0008] The technical solution adopted by the utility model is as follows:
[0009] A new root end adjustment bracket for a wind power blade drilling machine comprises a bottom bracket, the top of the bottom bracket is connected to a bottom linear guide rail, the bottom linear guide rail is connected to a bottom slider, an intermediate bracket is fixedly connected above the bottom slider, an intermediate linear guide rail is installed on the intermediate bracket, the intermediate linear guide rail is connected to an intermediate slider, a sliding wedge bracket is fixedly connected above the intermediate slider, a moving bracket slider is connected to the top of the sliding wedge bracket, the moving bracket slider is connected to the moving bracket linear guide rail, the moving bracket linear guide rail is arranged in an inclined shape, the moving bracket linear guide rail is connected to the moving bracket, and the moving bracket top is connected to a molded panel.
[0010] Furthermore, a bottom motor is installed on the bottom bracket, the bottom motor is connected to a first screw nut pair, the bottom of the intermediate bracket is connected to a screw bracket, and the first screw nut pair is installed in the screw bracket through a threaded connection.
[0011] Furthermore, an intermediate motor is installed on the intermediate bracket, and the intermediate motor is connected to a second screw nut pair, and the second screw nut pair is installed inside the sliding wedge bracket through a threaded connection.
[0012] Furthermore, the intermediate linear guide rail, the intermediate slider, the sliding wedge bracket, the motion bracket slider and the motion bracket linear guide rail are symmetrically arranged in two groups on the intermediate bracket.
[0013] Furthermore, an upper bracket is connected to the top of the intermediate bracket, and a guide mechanism arranged along the vertical direction is connected between the upper bracket and the profile panel.
[0014] Furthermore, the guiding mechanism includes a guiding linear guide rail installed on the upper bracket and a guiding sliding block installed on the panel and cooperating with the guiding linear guide rail.
[0015] Furthermore, a plurality of through holes and threaded holes are arranged on the bottom surface of the bottom bracket.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0017] The root end adjustment bracket of the utility model realizes automatic adjustment of the adjustment bracket in the left and right directions and the up and down directions through a compact structural design. Compared with the prior art, the adjustment bracket separates the left and right adjustment from the up and down adjustment, reducing the mutual influence between the movements.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] Example 1
[0027] A new root end adjustment bracket for a wind turbine blade drilling machine, such as Figure 1As shown, it includes a bottom bracket 1, the top of the bottom bracket 1 is connected to a bottom linear guide 7, the bottom linear guide 7 is connected to a bottom slider 8, an intermediate bracket 2 is fixedly connected above the bottom slider 8, an intermediate linear guide 12 is installed on the intermediate bracket 2, the intermediate linear guide 12 is connected to an intermediate slider 13, a sliding wedge bracket 14 is fixedly connected above the intermediate slider 13, the top of the sliding wedge bracket 14 is connected to a moving bracket slider 16, the moving bracket slider 16 is connected to a moving bracket linear guide 15, the moving bracket linear guide 15 is arranged in an inclined shape, the moving bracket linear guide 15 is connected to a moving bracket 17, and the top of the moving bracket 17 is connected to a molded panel 4.
[0028] As a preferred implementation scheme, a bottom motor 9 is installed on the bottom bracket 1, the bottom motor 9 is connected to a first screw nut pair 10, the bottom of the intermediate bracket 2 is connected to a screw bracket 11, and the first screw nut pair 10 is installed in the screw bracket 11 through a threaded connection.
[0029] The bottom linear guide 7 arranged on the bottom bracket 1 is connected to the intermediate bracket 2 through 12 bottom sliders 8, so that the intermediate bracket 2 can move linearly in the horizontal direction along the bottom linear guide 7 through the connection of the bottom sliders 8, and the transmission of the first screw nut pair 10 driven by the bottom motor 9 can realize the automatic movement of the intermediate bracket 2 under the drive of the bottom motor 9 and adjust the left and right directions.
[0030] Similarly, as a preferred embodiment, an intermediate motor 18 is installed on the intermediate bracket 2, and the intermediate motor 18 is connected to a second screw nut pair 19, and the second screw nut pair 19 is installed inside the sliding wedge bracket 14 through a threaded connection. In order to make the vertical adjustment support force more reasonable, the intermediate linear guide 12, the intermediate slider 13, the sliding wedge bracket 14, the motion bracket slider 16 and the motion bracket linear guide 15 are symmetrically arranged in two groups on the intermediate bracket 2.
[0031] The moving mechanism of the two groups of sliding wedge brackets 14 arranged on the intermediate bracket 2 enables the two sliding wedge brackets 14 to move relative to each other when the intermediate motor 18 drives the second screw nut pair 19 to transmit. When the two sliding wedge brackets 14 approach the middle, since the motion bracket linear guide 15 on the top of the sliding wedge bracket 14 is arranged in an inclined state, the sliding wedge bracket 14 moves in the horizontal direction, so that the vertical position of the motion bracket 17 connected to the motion bracket linear guide 15 is lifted, so that the motion bracket 17 drives the panel 4 to move upward. On the contrary, when the two sliding wedge brackets 14 move away from each other at both ends, the motion bracket 17 drives the panel 4 to move downward, thereby adjusting the up and down directions.

An implementation method of the guide mechanism 20 provided in this embodiment is as follows: the guide mechanism 20 includes a guide linear guide rail installed on the upper bracket 3 and a guide slider installed on the profile panel 4 and matched with the guide linear guide rail.
[0033] When the profile panel 4 is adjusted to move up and down in the vertical direction driven by the motion bracket 17, the guide mechanism 20 performs vertical guiding and limiting to ensure that the entire profile panel 4 moves strictly in the vertical direction, further ensuring the accuracy of its adjustment.
[0034] A plurality of through holes 5 and threaded holes 6 are provided on the bottom surface of the bottom bracket 1. The preferred solution provided in this embodiment is to provide 20 through holes 5. Through the cooperation between the through holes 5 and the anchor bolts, the entire bracket is firmly fixed to the ground, and two threaded holes 6 are provided near each through hole 5. The threaded holes 6 are used to assist in adjusting the horizontality of the bottom bracket 1 and further ensure the firm contact between the bracket and the ground.

The specific structure and connection method are existing technologies well known to technicians in this field, so they will not be repeated here.
