Description

Technical Field

[0001] This utility model relates to the field of hole processing technology, and in particular to an adjustable angular positioning device; used for housing parts of wind turbine yaw and pitch reducers, it serves to quickly find the angle and position the angular direction when there are flange holes on both sides of the part being processed and the two flange holes are angularly related. Background Technology

[0002] Currently, existing angular positioning devices for machining holes in parts achieve angular positioning by installing contour blocks and locating pins at the positioning holes, inserting the locating pins into the positioning holes.

[0003] However, the inventors of this application have found that this method is not applicable to parts with different flange hole center circles and different heights. After the part is redesigned, it is necessary to remake the angular positioning tooling according to the part height and center circle size. As the part specifications continue to increase, the number of corresponding tooling also increases, which greatly increases the difficulty of finding tooling and the cost of tooling manufacturing. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable angular positioning device that can integrate angular positioning fixtures and reduce the time spent searching for suitable fixtures, thereby effectively reducing the manufacturing cost of fixtures and ensuring angular positioning during part hole machining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable angular positioning device includes: a fixed base, wherein the fixed base is provided with a T-shaped slider, the T-shaped slider is provided with a fixing pin, and the fixing pin is connected to a replacement pin; The T-shaped slider is connected to the fixed base by a fixing bolt, and the fixing pin is connected to the T-shaped slider by a set screw.

[0006] In practical applications, the fixed base has a sliding groove, and the side wall of the fixed base has an oblong through hole corresponding to the position of the sliding groove; The groove is used to assemble the T-shaped slider, and the waist-shaped through hole is used to assemble the fixing bolt.

[0007] The T-shaped slider has a first through hole and a second through hole, and the first through hole and the second through hole are arranged perpendicularly to each other. The first through hole is used to assemble the retaining pin, and the second through hole is used to assemble the set screw.

[0008] Specifically, the adjustable angular positioning device is installed on the machine tool worktable plane or fixture plane by bolts, and the workpiece clamping position is higher than the installation position of the angular positioning device.

[0009] Furthermore, the diameter of the replacement pin for the hole-machined pin is determined according to the corresponding hole specifications.

[0010] Compared with the prior art, the adjustable angular positioning device of this utility model has the following advantages: In the adjustable angular positioning device provided by this utility model, when in use, the flange face of a part with a pre-machined flange hole is placed downwards. The fixed base of the adjustable angular positioning device is fixedly connected to the worktable fixture. After loosening the set screw and adjusting the fixing pin to a suitable height, the set screw is tightened. After loosening the fixing bolt and sliding the T-shaped slider back and forth to a suitable hole center circle size, the fixing bolt is tightened. After installing the replacement pin of the same specification as the hole, the angular orientation of the part can be fixed. Therefore, by adjusting the height and radial dimension of the angular positioning device and replacing the corresponding pin for the hole, the angular positioning tooling with multiple center circle sizes, multiple part heights, and multiple specifications of hole pins can be unified. This achieves the effect of integrating angular positioning tooling and reducing the time spent searching for suitable tooling, thereby effectively reducing the manufacturing cost of tooling and ensuring the angular positioning of the part hole machining.

[0013] This invention addresses the shortcomings of existing angular positioning devices, such as the inability to quickly locate the flange holes at both ends of parts at an angle, difficulties in tooling changeover, long tooling search times, and high tooling manufacturing costs. By adjusting the height and radial dimension of the angular pin and the corresponding pin for the hole on a single device, it achieves the goals of reducing tooling search time, lowering tooling costs, and enabling rapid angular positioning. In other words, for existing angular positioning tooling used in machining wind turbine yaw and pitch reducer housings, this invention integrates and unifies angular positioning tooling while ensuring angular positioning accuracy, thereby reducing the time spent searching for suitable tooling and ultimately lowering tooling manufacturing costs and waste.

[0016] Compared with the prior art, the adjustable angular positioning device described in this embodiment of the present invention has the following advantages: In the adjustable angular positioning device provided in this embodiment of the utility model, when using it, the flange face of the part with the pre-machined flange hole is placed downwards. The fixed base 1 of the adjustable angular positioning device is fixedly connected to the workbench fixture. After loosening the set screw 6 and adjusting the fixing pin 3 to a suitable height, the set screw 6 is tightened. After loosening the fixing bolt 2 and sliding the T-shaped slider 5 back and forth to a suitable hole center circle size, the fixing bolt 2 is tightened. After installing the replacement pin 4 of the same specification as the hole, the angular orientation of the part can be fixed. Therefore, by adjusting the height and radial dimension of the angular positioning device and replacing the corresponding pin for the hole, the angular positioning tooling with multiple center circle sizes, multiple part heights, and multiple specifications of hole pins can be unified. This achieves the effect of integrating angular positioning tooling and reducing the time to find suitable tooling, thereby effectively reducing the manufacturing cost of tooling and achieving the purpose of ensuring the angular positioning of the part hole machining.

[0017] In practical applications, such as Figure 1 As shown, the fixed base 1 may have a sliding groove, and the side wall of the fixed base 1 may have an oblong through hole corresponding to the sliding groove position. The groove can be used to assemble the T-shaped slider 5, and the waist-shaped through hole can be used to assemble the fixing bolt 2.

[0018] Among them, such as Figure 1 As shown, the T-shaped slider 5 can have a first through hole and a second through hole, and the first through hole and the second through hole can preferably be arranged perpendicularly; The first through hole can be used to assemble the fixing pin 3, and the second through hole can be used to assemble the set screw 6.

[0019] Specifically, such as Figure 1 As shown, the adjustable angular positioning device provided in this embodiment of the present invention can be installed on the machine tool worktable plane or the fixture plane by bolts, and the clamping position of the part should be higher than the installation position of the angular positioning device.

[0020] Furthermore, the diameter of the hole machining pin, i.e., the replacement pin 4, is determined according to the corresponding hole specifications.

[0021] In summary, the adjustable angular positioning device provided by this utility model embodiment has the following advantages: 1. The locating pin can not only satisfy vertical movement, but also simultaneously satisfy any size height positioning and adjustment. 2. The diameter of the angular locating pin is movable, and the diameter can be changed by the T-shaped slider to achieve arbitrary size adjustment; 3. The head of the angular locating pin is equipped with a replaceable replacement pin. Only the corresponding pin needs to be replaced according to the hole diameter, and the entire locating pin does not need to be replaced. IV. Adjust the pitch circle diameter and the height of the manual locating pin using the T-slider.
