Description

Technical Field

[0001] The utility model relates to a gantry milling workbench, in particular to a gantry milling workbench suitable for an anti-distortion ring. Background Art

[0002] The anti-distortion ring is installed on the shaft of a large wind turbine to prevent the shaft from deforming due to long-term rotation and affecting the normal use of the wind turbine. The anti-distortion ring is transformed into a ring structure with various structural holes and mounting holes. The surface of the anti-distortion ring of some wind turbines with special structures is not flat, but has steps or a certain taper. The table top of the clamping platform of a general gantry milling machine is a flat structure. In this way, the anti-distortion ring is prone to shaking when placed, resulting in inaccurate turning and milling position, affecting the accuracy of the anti-distortion ring. Therefore, the turning and milling clamping platform is required to have a certain degree of flexible adjustment function to adapt to anti-distortion rings of different forms. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a gantry milling workbench for an anti-distortion ring.

[0004] To achieve this purpose, the structure adopted by the utility model is: a gantry milling workbench for an anti-distortion ring, comprising a base, on which a circle of pressing plates are arranged around the blank of the anti-distortion ring, the blank is in a ring shape, one end of the pressing plate is pressed on the edge of the blank, and the other end is connected to the base through a column, and a plurality of equal-height shims are arranged below the edge of the blank, the equal-height shims are fixed on the base in a ring shape, and a plurality of adjustable supports are arranged between the equal-height shims and the inner ring of the blank.

[0005] A screw rod is arranged in the center of the pressing plate, one end of the screw rod is connected to the pressing plate, and the other end is connected to the base.

[0006] The equal-height washers are hollow iron pipes with equal heights.

[0007] A copper backing plate is arranged between the pressing plate and the blank.

[0008] The adjustable support comprises a conical base, a rubber block is connected to the conical base via a screw rod, and a suction cup is arranged on the top of the rubber block.

[0009] The beneficial effects are: the structural design of the utility model is reasonable and ingenious, the equal-height pads and the pressure plate fix the edge of the blank, and the adjustable support supports the inner edge of the blank, so that the blank can be evenly supported on both sides of the turning and milling force point during the turning and milling process, avoiding deformation due to turning and milling. At the same time, the adjustable support can be adjusted according to the shape of different blanks, and can avoid slipping of the blank during the turning and milling process. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be described by way of examples with reference to the accompanying drawings, in which:

[0011] Figure 1 It is the front view of the utility model;

[0012] Figure 2 Schematic diagram of the adjustable support structure. DETAILED DESCRIPTION

[0013] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0014] In the description of the utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0015] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components; the fixed connection can be welding or gluing. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0016] like Figure 1 The gantry milling workbench for the anti-distortion ring shown includes a base 1, on which the blank 7 of the anti-distortion ring is placed. The blank 7 is annular, and a plurality of pressing plates 6 are arranged around the blank 7 on the base 1. One end of the pressing plate 6 is pressed above the edge of the blank 7, and the other end is connected to the base 1 through a column 4. A plurality of equi-height pads 2 are arranged below the outer edge of the blank 7. The equi-height pads 2 interact with the pressing plates 6 to fix the edge of the blank 7. The equi-height pads 2 are hollow iron pipes fixed to the base 1 with equal height. A plurality of adjustable supports 3 are arranged between the equi-height pads 2 and the inner edge of the blank 7. The adjustable supports 3 balance the supporting forces on both sides of the turning and milling pressure points to prevent the blank 7 from sinking inwards during the turning and milling process. The adjustable supports 3 can be adjusted according to the height of the contact surface of the blank 7.

[0017] A screw rod 5 is arranged in the center of the pressing plate 6, and the screw rod 5 is connected to the base. The degree of pressing of the pressing plate 6 on the blank 7 can be adjusted by rotating the screw rod 5. A copper pad is arranged between the pressing plate 6 and the blank 7 to increase the contact area between the pressing plate 6 and the blank 7, disperse the pressure, and prevent the pressing plate 6 from scratching the blank 7.

[0018] like Figure 2 As shown, the adjustable support 3 includes a base 31, which is a conical structure. The base 31 is fixed on the base 1. The top of the base 31 is connected to a rubber block 33 through a screw 32. The height of the rubber block 33 can be adjusted by rotating the screw 32. The screw 32 can be replaced by a lifting structure such as a cylinder. The adjustable support 3 can adapt to billets of different shapes so that the billets can be evenly supported. The rubber block 33 has a shock-absorbing effect. While supporting the billet 7, it reduces the position caused by vibration. At the same time, the edge of the rubber block 33 will not cause dents to the billet 7. A suction cup 34 is provided on the top of the rubber block 33. The suction cup 34 is a rubber suction cup, which can increase friction and prevent the billet 7 from slipping due to vibration during turning and milling.

[0019] The above is based on the enlightenment of this utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of ​​this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
