DETAILED DESCRIPTION
[0023] 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.
[0024] An embodiment provided by the utility model: Figure 1 As shown, a clamping device for drilling a wind turbine flange comprises a clamping platform 1, a motor 2, a clamping center body 3, a support assembly 4 and a wind turbine flange positioning mechanism 5.
[0025] like Figure 3 As shown, the side of the clamping center body 3 is polygonal, and each side of the clamping center body 3 is connected to a set of wind turbine flange positioning mechanisms 5, and the wind turbine flange positioning mechanisms 5 are evenly distributed around the clamping center body 3. The ring-shaped arrangement of multiple sets of wind turbine flange positioning mechanisms 5 clamps and fixes multiple points of the wind turbine flange to be drilled, thereby maintaining the balance and stability of the wind turbine flange during processing.
[0026] like Figure 3 As shown, the wind turbine flange positioning mechanism 5 includes a first hydraulic press 51 and a clamping assembly 52. The body of the first hydraulic press 51 is fixed on the clamping center body 3. The output end of the first hydraulic press 51 is fixedly connected to the clamping assembly 52. The clamping assembly 52 is slidably connected to the body of the first hydraulic press 51. According to the size of the wind turbine flange to be drilled, all the first hydraulic presses 51 simultaneously drive the clamping assembly 52 to adjust the position. After matching the position of the wind turbine flange to be drilled, the wind turbine flange to be drilled can fall on the clamping assembly 52, ensuring the accuracy of the positioning of the wind turbine flange to be drilled, so as to perform a stable drilling operation. Through the adjustment of the first hydraulic press 51, the clamping device can perform drilling processing on wind turbine flanges of different diameters.
[0027] like Figure 4As shown, the clamping assembly 52 includes a fixing seat 521, an inner stopper 522 and an outer stopper 523. The fixing seat 521 is fixed to the output end of the first hydraulic press 51. One end of the fixing seat 521 close to the first hydraulic press 51 is connected to the inner stopper 522, and the other end is connected to the outer stopper 523. The first hydraulic press 51 pushes the clamping assembly 52 outward together, so that the inner stopper 522 contacts and limits the inner edge of the wind turbine flange, and the outer stopper 523 adjusts the position to limit the outer edge of the wind turbine flange. The inner stopper 522 and the outer stopper 523 realize the inner and outer clamping of the wind turbine flange with a hole falling in the clamping assembly 52, and the two-way limit, so as to ensure that the wind turbine flange is firmly clamped in an accurate position, increase the stability of the clamping and fixing of the wind turbine flange, so that accurate drilling can be achieved, and the quality of wind turbine flange processing is improved.
[0028] like Figure 4 and Figure 5 As shown, the outer limiter 523 includes an adjustable base 5231, a slide rail 5233, a second hydraulic press 5234, a movable limiter 5235 and a roller 5236. The movable limiter 5235 is slidably connected to the adjustable base 5231, the body of the second hydraulic press 5234 is fixed inside the adjustable base 5231, and the output end of the second hydraulic press 5234 is fixedly connected to the movable limiter 5235. When the outer limiter 523 is fixed to the outer edge of the flange to be drilled, the second hydraulic press 5234 drives the movable limiter 5235 to move inward according to the size of the flange to be drilled, and the roller 5236 of the movable limiter 5235 moves in the slide rail 5233, so that the movable limiter 5235 stably squeezes the outer edge of the flange to be drilled, completing the outer clamping operation. The adjustment and clamping operation of the movable limiter 5235 on the adjustable base 5231 makes the device suitable for wind turbine flanges with different width specifications.
[0029] like Figure 4 , Figure 5 and Figure 6As shown, a first gasket 5221 is arranged above the inner limiter 522, a second gasket 5232 is fixed on the surface of the adjustable base 5231, and a third gasket 5237 is arranged on the side of the movable limiter 5235. The first gasket 5221, the second gasket 5232 and the third gasket 5237 are all made of flexible materials, and the vertical surfaces of the second gasket 5232 and the third gasket 5237 are arc-shaped. When the clamping assembly 52 clamps the wind turbine flange to be drilled, the bottom surface of the wind turbine flange contacts the first gasket 5221 and the second gasket 5232, the inner side contacts the first gasket 5221, and the outer side contacts the third gasket 5237. Each contact position is protected by a gasket to ensure that the surface of the flange to be drilled will not be damaged. At the same time, the first gasket 5221 on the inner and outer sides is an arc-shaped with a convex middle, and the third gasket 5237 is an arc-shaped with a concave middle, which matches the shape of the wind turbine flange during the clamping process, fits the wind turbine flange better, expands the contact area between the two, increases friction, plays an anti-slip role, and makes the clamping effect more stable.
[0030] like Figure 1 As shown, the clamping center body 3 is rotatably connected to the clamping platform 1, the body of the motor 2 is located inside the clamping platform 1, the output end of the motor 2 is fixedly connected to the clamping center body 3, and the wind power flange positioning mechanism 5 is arranged on the side of the clamping center body 3. Figure 3 As shown, all the clamping components 52 are regarded as a circle, and its center is on the same vertical line as the center of the motor 2. The motor 2 drives the clamping center body 3 and multiple groups of wind turbine flange positioning mechanisms 5, and rotates at an angle consistent with the drilling positions, and drills multiple positions on the same wind turbine flange. The drill bit of the equipment does not need to be moved during the drilling process at different positions of the same flange. The clamping center body 3 rotates and drills multiple times. It only needs to rotate the flange, which saves the operation of changing the position of the drill bit, simplifies the operation steps, increases the accuracy of the drill bit relative to the wind turbine flange, and improves the quality of the hole. Since the displacement distances of all the clamping components 52 are always equal during the positioning of the wind turbine flange to be drilled, it can be ensured that the wind turbine flange to be drilled is coaxial with the motor 2, and each hole opening position is accurately corresponding to the drill bit during the rotation process.
[0031] like Figure 1 and 2 As shown, a support assembly 4 is provided between the clamping platform 1 and the clamping center body 3, and the support assembly 4 includes a rotating connection member 41 and a support frame 42. The rotating connection member 41 is rotatably connected to the clamping platform 1, and the rotating connection member 41 and the clamping center body 3 are fixedly connected by multiple groups of support frames 42. When the motor 2 drives the clamping center body 3 to rotate, the support assembly 4 rotates simultaneously, and the support frame 42 stably supports the clamping center body 3 at multiple positions, ensuring that the device can run smoothly during the drilling process.
[0032] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
