Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a positioning device for forging wind turbine gear rings. Background Technology

[0002] During the forging process, the raw materials need to be fixed on the processing equipment for cutting, stamping and other operations. In order to ensure processing accuracy and safety, a positioning device is needed to ensure the stability and accuracy of the position of the raw materials. Existing positioning devices usually use clamps or molds, but they have problems such as low accuracy and poor adaptability to forgings of different sizes.

[0003] Patent CN211489496U discloses a positioning device for forging processing. The positioning and clamping of the forging is achieved by positioning blocks and positioning plates. The operation is cumbersome and cannot be positioned and clamped in multiple directions at the same time. The mounting block and the threaded block are rotatably connected to achieve lifting. The transmission directions of the rotating shaft and the threaded block are perpendicular. It is difficult to flip the forging by transmission rotation, and the forging is unstable when flipped without being fixed.

[0004] Patent CN219665032U discloses a positioning device for forging processing, which only performs clamping and positioning in two directions. During processing, the forging is prone to displacement, which reduces the processing accuracy.

[0005] Therefore, it is necessary to improve the positioning device used for processing wind turbine gear ring forgings in the existing technology. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects in the existing technology and provide a positioning device for processing wind turbine gear ring forgings. By moving the fine adjustment component, it acts on the positioning component and moves back and forth along the length of the first guide groove and the second guide groove, in a state of approaching or separation. It is suitable for round forgings or forgings with symmetrical parts. It is easy to operate. Combined with the positioning components that are set in pairs and are set opposite to each other along the length of the first guide groove and the second guide groove, the positioning is more accurate and stable.

[0007] To achieve the above-mentioned technical effects, the technical solution of this utility model is: a positioning device for processing wind turbine gear ring forgings, comprising:

[0008] The base has a supporting surface and is provided with a first guide groove and a second guide groove that extend and intersect and are coplanar with the supporting surface;

[0009] Positioning components are arranged in pairs, respectively positioned opposite each other along the length of the first guide groove and the second guide groove, and reciprocate.

[0010] A movable fine-tuning component is located below the supporting surface and connected to the base, while simultaneously acting on the positioning component to bring them closer together or separate them.

[0011] The first guide groove and the second guide groove extend through the thickness of the base.

[0012] A preferred technical solution is that the movable fine-tuning component includes a slider, a guide rod, and a screw guide. The extension direction of the screw guide is consistent with the thickness direction of the base. One end is rotatably connected to the base, and the other end is connected to a driving component. The slider is threadedly connected to the screw guide. One end of the guide rod is rotatably connected to the slider via a first rotating shaft, and the other end is rotatably connected to the positioning component via a second rotating shaft. The extension directions of both the first and second rotating shafts are perpendicular to the extension direction of the first or second guide groove.

[0013] A preferred technical solution is that the guide rods are of equal length.

[0014] A preferred technical solution is that the base is provided with a guide rail, the extension direction of the guide rail is consistent with the groove length direction of the first guide groove and the second guide groove, and the positioning member is in concave-convex fit with the guide rail and slidably connected.

[0016] A preferred technical solution is that the base is provided with a support plate, and the support plate is coplanar with the support surface or is set at an acute angle.

[0017] A preferred technical solution is that one end of the supporting sliding plate is rotatably connected to the base via a third rotating shaft, and the other end is rotatably connected to a corresponding telescopic rod via a third rotating shaft, wherein the telescopic rod is fixedly connected to the base.

[0018] A preferred technical solution is that the positioning member is provided with an arc surface, and the arc surface faces another positioning member that is opposite to the groove length of the first guide groove or the second guide groove.

[0019] A preferred technical solution is that the positioning component is provided with a magnetic suction element.

[0020] A preferred technical solution is that the guide rail is provided with an elastic element on its periphery that extends in the same direction as the first guide groove or the second guide groove.

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0029] The terms "below" and "end" refer to the normal operating state of the positioning device for processing wind turbine gear ring forgings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] like Figures 1-4 As shown, the positioning device for processing wind turbine gear ring forgings of this utility model includes a base 1, positioning components 2, and a movable fine-tuning component 3. The base 1 has a supporting surface 10 and is provided with a first guide groove 101 and a second guide groove 102 that extend and intersect and are coplanar with the supporting surface 10. The first guide groove 101 and the second guide groove 102 penetrate along the thickness direction of the base 1. The positioning components 2 are arranged in pairs and are respectively arranged opposite to each other along the groove length direction of the first guide groove 101 and the second guide groove 102 and reciprocate. The movable fine-tuning component 3 is located below the supporting surface 10 and is connected to the base 1. It also acts on the positioning components 2 to make them move closer together or separate.

[0032] The moving fine-tuning component 3 acts simultaneously on the positioning component 2 and reciprocates along the groove length direction of the first guide groove 101 and the second guide groove 102, so that they are in a close-to-each state or a separate state. This is suitable for round or symmetrical forgings and is easy to operate. Combined with the positioning components 2 which are set in pairs and are set opposite to each other along the groove length direction of the first guide groove 101 and the second guide groove 102, the positioning is more accurate and stable.

[0033] like Figures 2-3 As shown, in order to achieve the effect of the moving fine-tuning component acting on the positioning component at the same time, the moving fine-tuning component 3 further includes a slider 30, a guide rod 32 and a screw guide 31. The extension direction of the screw guide 31 is consistent with the thickness direction of the base 1. One end is rotatably connected to the base 1 and the other end is connected to the driving component 33. The slider 30 is threadedly connected to the screw guide 31. One end of the guide rod 32 is rotatably connected to the slider 30 through a first rotating shaft (unmarked) and the other end is rotatably connected to the positioning component 2 through a second rotating shaft (unmarked). The extension directions of the first rotating shaft and the second rotating shaft are both perpendicular to the extension direction of the first guide groove 101 or the second guide groove 102. The screw guide 31 rotates through the drive 33, causing the slider 30 to reciprocate along the extension direction of the screw guide 31. This, in turn, causes the guide rod 32 to extend and retract along the radial direction of the screw guide 31 at an acute angle. This, in turn, causes the positioning member 2 to reciprocate along the groove length direction of the first guide groove 101 and the second guide groove 102, respectively. This achieves the relative positioning members 2 to move closer together or separate, similar to the principle of opening an umbrella.

[0034] In some preferred embodiments, the guide rods 32 are of equal length. Unequal lengths of the guide rods 32 can also achieve a state where the guide components are close together or separated, but the uneven force when the forging (not shown) and the positioning component 2 abut against each other can easily lead to unstable positioning and damage to the moving fine-tuning component 3.

[0035] like Figure 4As shown, to improve the accuracy and stability of the positioning component during reciprocating motion and positioning operation, the base 1 is provided with a guide rail 111. The extension direction of the guide rail 111 is consistent with the groove length direction of the first guide groove 101 and the second guide groove 102, respectively. The positioning component 2 is in concave-convex fit with the guide rail 111 and slidably connected. Furthermore, the periphery of the guide rail 111 is sleeved with an elastic element (not shown) consistent with the extension direction of the first guide groove 101 or the second guide groove 102. The elastic element includes a first segmented elastic element (not shown) and a second segmented elastic element (not shown) respectively disposed at both ends of the positioning component 2. The first segmented elastic element is located near the end of the intersection of the extension of the first guide groove 101 and the second guide groove 102, and the length of the first segmented elastic element is less than that of the second segmented elastic element. The design of elastic elements further improves the accuracy and stability of the positioning elements during reciprocating motion and positioning operation. The length of the first segment elastic element is shorter than that of the second segment elastic element. The first segment elastic element is in a stretched state during operation, generating traction force, while the second segment elastic element is in a compressed state, generating support force. This helps the positioning elements to tend to move closer together, which not only makes them contact the forging more closely but also increases the contact force, thereby improving the positioning stability of the forging.

[0036] The base 1 is provided with a positioning groove 11 that extends in the same direction as the screw guide 31. The opening of the positioning groove 11 faces away from the supporting surface 10, and the center line of the positioning groove 11 coincides with the center line of the screw guide 31. This facilitates the accurate determination of the placement position of the forging, avoiding the need to move it after placement, which would increase labor intensity and affect work efficiency.

[0037] like Figures 2-3 As shown, the optimized base structure facilitates automatic placement and adjustment of forgings. The base 1 is equipped with a support plate 12, which is coplanar with or at an acute angle to the support surface 10. When the support plate 12 is coplanar with the support surface 10, it provides support and improves the support strength of the base 1. When the support plate 12 is at an acute angle to the support surface 10, it deviates from the support surface 10 to form a receiving groove (not marked). This design helps prevent friction between the lifting device and the base 1 when placing forgings, and allows for free movement within the receiving groove, facilitating the lifting device's deployment and retraction. It also improves the stability when placing forgings and reduces damage or scratches to the base 1 and the surface of the forgings.

[0038] Furthermore, one end of the supporting plate 12 is rotatably connected to the base 1 via a third pivot (unmarked), and the other end is rotatably connected to a corresponding telescopic rod 121 via a third pivot (unmarked). The telescopic rod 121 is fixedly connected to the base 1. This achieves a state where the supporting plate 12 and the supporting surface 10 are coplanar or form an acute angle. Furthermore, the telescopic rod 121 is a cylinder.

[0039] To further increase the contact area between the positioning element 2 and the forging, resulting in more uniform force distribution and more stable positioning, the positioning element 2 is provided with an arc surface 20, which faces another positioning element 2 along the groove length of the first guide groove 101 or the second guide groove 102. Furthermore, the positioning element 2 is provided with a magnetic suction element.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
