Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of machining positioning, and in particular to a positioner for positioning the machining position of an impeller. Background Technology
[0002] Among the many types of axial flow pumps, the impeller is an essential component. Its outer diameter and blade angle determine the pump's output flow rate and head, and are also important indicators of the pump's efficiency during operation. In manufacturing, it has been found that turning the outer diameter of the impeller is quite difficult because it is assembled from multiple blades and a hub. The outer diameter of the impeller consists of blades with different angles, and during lathe machining, the cutting tool is constantly in an intermittent cutting state, resulting in high impact force, small depth of cut, and slow feed rate. This leads to low turning efficiency and difficulty in controlling the machining time. Utility Model Content
[0003] This utility model discloses a positioner for locating the machining position of an impeller, which can quickly locate the area of the blade that needs to be precision machined, thereby increasing turning efficiency.
[0004] A positioner for positioning the machining position of an impeller, comprising:
[0005] A mounting bracket is used to secure the hub cavity cover.
[0006] A first slide bar is slidably disposed on the fixed frame along a first direction, and the distal end of the first slide bar extends outside the fixed frame;
[0007] The second slide bar is slidably disposed on the distal end of the first slide bar in a second direction; the bottom of the second slide bar is provided with a sliding head;
[0008] Wherein, the extension of the first direction and the extension of the second direction intersect;
[0009] The second slide bar is configured to move along a second direction under the influence of gravity.
[0010] In some designs, the fixing frame is rotatably equipped with several stop members, and the several stop members form a clamping space;
[0011] When the fixing bracket is fixed on the hub cavity cover, several of the stop members abut against the hub cavity cover.
[0012] In some embodiments, at least one of the stop members is movable on the fixture to change the size of the clamping space.
[0013] In some embodiments, the stop member, which is movable on the fixed frame in a first direction, has a first locking portion for restricting the movement of the stop member on the fixed frame.
[0014] In some embodiments, the fixing frame has several extensions, and each extension has a stop member at its end.
[0015] In some embodiments, the mounting bracket is provided with a sliding groove, and the stop member is embedded in the sliding groove and moves along the extension direction of the sliding groove.
[0016] In some designs, the swashplate is detachably connected to the second slide bar.
[0017] In some embodiments, the fixing frame is provided with a plurality of second locking parts, which are used to restrict the movement of the first slide bar in a first direction.
[0018] In some schemes, the extension of the first direction is perpendicular to the extension of the second direction.
[0019] In some designs, the outer wall of the first slide bar is marked with graduations along its own axial direction.
[0020] The technical solution adopted in this utility model can achieve the following beneficial effects:
[0021] The positioner disclosed in this application for locating the machining position of an impeller involves mounting a fixed frame on the hub cavity cover. The length of the distal end of the first sliding rod extending beyond the fixed frame is adjusted according to the required diameter of the impeller, and the scriber is placed at the highest point of the blade. The operator then rotates the fixed frame, causing the second sliding rod to rotate circumferentially. During this rotation, the second sliding rod moves downwards along a second direction due to changes in blade height and its own gravity, ensuring the scriber remains in contact with the upper surface of the blade. As the fixed frame rotates, the scriber carves the required contour of the blade. During machining, only the scribe lines on the blade need to be followed, greatly increasing machining efficiency and reducing machining difficulty. Attached Figure Description

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

[0029] A positioner for locating the machining position of an impeller, please refer to... Figure 1 and Figure 2 As shown, it includes a fixed frame 10, a first slide bar 20, and a second slide bar 30.
[0030] like Figure 1 and Figure 2 As shown, the mounting bracket 10 is used to fix it to the hub cavity cover. The mounting bracket 10 provides a mounting base for the first slide bar 20 and is also an important component for impeller machining positioning.
[0031] Specifically, the mounting bracket 10 is rotatably equipped with several abutment members 12, which form a clamping space. When the mounting bracket 10 is fixed on the hub cavity cover, the abutment members 12 abut against the hub cavity cover, thereby completing the installation of the mounting bracket 10 on the hub cavity cover. The abutment members 12 are rotatable, which greatly reduces the friction when the mounting bracket 10 rotates, thus facilitating the rotation of the mounting bracket 10 on the hub cavity cover.
[0032] More specifically, at least one stopper 12 can move on the mounting bracket 10 to change the size of the clamping space. By moving the stopper 12 and changing the size of the clamping space, the mounting bracket 10 can be installed on hub covers of different sizes, thus providing versatility.
[0033] like Figure 1 and Figure 2 As shown, the stop member 12, which can move along a first direction on the fixing frame 10, has a first locking part 121. The first locking part 121 is used to restrict the movement of the stop member 12 on the fixing frame 10. Before the fixing frame 10 is installed on the wheel hub cover, the first locking part 121 releases the stop member 12, allowing the stop member 12 to move freely and adjust to a suitable position according to different sizes of wheel hub covers. After the fixing frame 10 is installed on the wheel hub cover, and all the stop members 12 abut against the wheel hub cover, the first locking part 121 locks the stop members 12, restricting the movement of the stop members 12, thereby stably installing the fixing frame 10 on the wheel hub cover, so that the fixing frame 10 can only rotate in its own circumferential direction.
[0034] Specifically, the fixed frame 10 is provided with a sliding groove 10a, and the stop member 12 is embedded in the sliding groove 10a and moves along the extension direction of the sliding groove 10a.
[0035] In this preferred embodiment, the first locking part 121 is a nut, and the movable stop part 12 is a bearing. The threaded end of the nut passes through the slide groove 10a and is threadedly connected to the bearing. When the stop part 12 needs to move, the nut is loosened, and the bearing can move along the slide groove 10a; when the stop part 12 needs to be locked, the nut is tightened, and the movement of the bearing on the slide groove 10a is restricted by friction.
[0036] Correspondingly, the other stop components 12 are also bearings, and are mounted on the fixed frame 10 by screw rotation.
[0037] like Figure 1 and Figure 2 As shown, the mounting bracket 10 has a plurality of extensions 11, and each extension 11 has a stop member 12 at its end. By providing a plurality of extensions 11 to the mounting bracket 10, the number of stop members 12 installed is increased, thereby increasing the stability of the mounting bracket 10 on the hub cavity cover.
[0038] In this preferred embodiment, there are two extensions 11, so that the fixing bracket 10 is in a Y-shape. This allows the fixing bracket 10 to be positioned at three points when it is installed on the wheel hub cover, ensuring the stability of the fixing bracket 10 when it is installed on the wheel hub cover while minimizing manufacturing costs.
[0039] like Figure 1 and Figure 2As shown, the first slide rod 20 is slidably mounted on the fixed frame 10 along the first direction, and the distal end of the first slide rod 20 extends outside the fixed frame 10. The second slide rod 30 is slidably mounted on the distal end of the first slide rod 20 along the second direction, and the bottom of the second slide rod 30 is provided with a sliding head 31. The extension lines of the first direction and the extension lines of the second direction intersect, and the second slide rod 30 moves along the second direction under the action of gravity.
[0040] In use, the length of the distal end of the first slide rod 20 extending beyond the fixed frame 10 is adjusted according to the diameter of the impeller to be machined, and the scribing head 31 is placed at the highest point of the blade. At this time, the operator rotates the fixed frame 10, which in turn causes the second slide rod 30 to rotate circumferentially. During this rotation, the second slide rod 30 moves downwards along the second direction due to the change in blade height and its own gravity, ensuring that the scribing head 31 remains in contact with the upper surface of the blade. As the fixed frame 10 rotates, the scribing head 31 carves the contour of the blade to be machined.
[0041] In this preferred embodiment, the extension lines of the first direction and the second direction are perpendicular. This arrangement makes it easier for the operator to use, allowing the scribing head 31 to better scribble the area to be processed on the blade.
[0042] It should be noted that the first direction is as follows: Figure 1 As shown in L1, the second direction is as follows Figure 1 As shown in L2, the distal end of the first slide bar 20 refers to the end that is far away from the fixing frame 10.
[0043] It should also be noted that the second slide bar 30 moves along the second direction under the action of gravity because the weight of the second slide bar 30 is greater than the sliding friction between the second slide bar 30 and the first slide bar 20.
[0044] In a preferred embodiment, the fixing frame 10 is provided with a first sleeve 13, and the distal end of the first slide rod 20 passes through the first sleeve 13 and is slidably connected to the second slide rod 30. The first sleeve 13 provides a mounting base for the first slide rod 20 to be mounted on the fixing frame 10, and provides guidance for the movement of the first slide rod 20 in the first direction, ensuring that the first slide rod 20 slides smoothly in the first direction.
[0045] It should be noted that in this embodiment, the slide groove 10a also extends along the first direction. Therefore, the first sleeve 13 has a certain height. When the first slide rod 20 is installed in the first sleeve 13, there is a gap between the first slide rod 20 and the fixing frame 10. The distance of this gap is greater than the height of the first locking part 121, so that there will be no movement interference between the first slide rod 20 and the first locking part 121.
[0046] In a preferred embodiment, the distal end of the first slide rod 20 is provided with a second sleeve 21, and the bottom of the second slide rod 30 passes through the second sleeve 21 and is slidably connected to the first slide rod 20. The second sleeve 21 provides a mounting base for the second slide rod 30 to be mounted on the first slide rod 20, and provides guidance for the movement of the second slide rod 30 in the second direction, ensuring that the second slide rod 30 slides smoothly in the second direction.
[0047] like Figure 1 and Figure 2 As shown, the mounting bracket 10 is provided with several second locking parts 14, which are used to restrict the movement of the first slide rod 20 in the first direction. During the process of adjusting the length of the distal end of the first slide rod 20 extending outside the mounting bracket 10 according to the diameter to be processed on the impeller, the second locking parts 14 are released, allowing the first slide rod 20 to move freely in the first direction, thereby adjusting the length extending outside the mounting bracket 10. When the length of the distal end of the first slide rod 20 extending outside the mounting bracket 10 is adjusted, the second locking parts 14 lock the first slide rod 20, restricting its movement in the first direction. This ensures that during the rotation of the mounting bracket 10, the first slide rod 20 follows the circumferential rotation of the mounting bracket 10 and does not move radially, thus ensuring the stability of the engraving.
[0048] In this embodiment, the second locking part 14 is a nut, and the first sleeve 13 of the fixing bracket 10 is provided with several threaded holes. The first slide rod 20 is locked or released by passing the end of the nut through the threaded holes and by turning the nut so that the end of the nut abuts or separates from the outer wall of the first slide rod 20.
[0049] In this embodiment, the outer wall of the first slide bar 20 is provided with a scale 15 along its own axial direction, which facilitates observation and recording of the length of the first slide bar 20 extending to the outside of the fixing frame 10.
[0050] like Figure 1 and Figure 2 As shown, the scribing head 31 is detachably connected to the second slide bar 30. Since the scribing head 31 is used to scribble on the hard blade, it wears out quickly. To facilitate the replacement of the new scribing head 31 and the polishing of the old scribing head 31, the scribing head 31 is designed to be detachable from the second slide bar 30.
[0051] Specifically, the cutting head 31 is locked to the bottom of the second slide bar 30 by the third locking part 32. When the third locking part 32 is loosened, the cutting head 31 can be removed; correspondingly, when the third locking part 32 is tightened, the cutting head 31 is firmly fixed to the bottom of the second slide bar 30.
[0052] In this embodiment, the third locking part 32 is a nut, and the second slide rod 30 has a threaded hole on the side wall near the bottom. The first slide rod 20 is locked or released by passing the end of the nut through the threaded hole and by turning the nut so that the end of the nut abuts or separates from the outer wall of the slide head 31.
[0053] In this embodiment, the cutting head 31 is made of cemented carbide to increase its hardness.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0055] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved.
