Detailed implementation manners

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 3 together. An impeller detection device according to an embodiment of the present utility model is used to quickly detect whether the quality of the impeller meets the production requirements.

[0032] For the convenience of explaining the detection process of the impeller detection device, the present utility model takes the impeller body 10 shown in Figure 6 as the impeller to be detected for illustration. The impeller body 10 can be applied to the snow removal device of a snow sweeping robot and used as the snow throwing impeller of the snow removal device. The impeller body 10 is only used for illustration and does not limit the types of impellers that the present utility model can detect. As shown in Figure 6 the impeller body 10 may include a hub 101, a plurality of blades 102 and a central shaft 103. The central shaft 103 is arranged at the central position of the hub 101. The inside of the central shaft 103 can be hollow to form an impeller shaft hole 104. The impeller shaft hole 104 can be used to connect to the output end of an external driving device to drive the whole impeller body 10 to rotate. The plurality of blades 102 are arranged on the hub 101, and the plurality of blades 102 are circumferentially distributed on the hub 101. The output end of the driving device can be, but is not limited to, a motor shaft or a reducer output shaft.

[0033] A first assembly hole 105 can be opened on the impeller shaft hole 104 for a positioning member such as a bolt to be inserted to realize the connection and positioning between the impeller shaft hole 104 and the output end of the external driving device, and improve the stability and reliability of the connection between the two.

[0034] Please refer to Figures 1 to 3 together. The impeller detection device includes a flatness detection structure 1, a shaft hole detection member 2 and a perpendicularity detection disk 4.

[0035] The flatness detection structure 1 has a plane. The plane is used to detect the flatness of the hub 101.

[0036] The shaft hole detection member 2 is erected on the plane of the flatness detection structure 1. The shaft hole detection member 2 can be rod-shaped, and the shaft hole detection member 2 is used to detect the shape and size of the impeller shaft hole 104.

[0037] The perpendicularity detection disk 4 is provided with a detection disk shaft hole 41, and a plurality of radially extending blade detection grooves 42 are opened on the perpendicularity detection disk 4. The perpendicularity detection disk 4 is used to detect the perpendicularity of the blades 102.

[0038] In this embodiment, the flatness of the hub 101 can be detected by setting a flatness detection structure 1 with a plane, the shape and size of the impeller shaft hole 104 can be detected by a shaft hole detection member 2, and the perpendicularity of the blade 102 can be detected by a perpendicularity detection disc 4, so that a detection device can complete multiple geometric tolerance detections. The multiple measurement processes separated in the related art are simplified into one, the detection operation is simple and convenient, the work efficiency is greatly improved, and the structure of the utility model is simple and the manufacturing cost is low.

[0039] Refer to Figure 5 , when it is necessary to detect the flatness of the hub 101, the impeller body 10 is sleeved on the shaft hole detection member 2, and the shaft hole detection member 2 is inserted into the impeller shaft hole 104. Various methods can be used to determine whether the flatness of the hub 101 meets the production requirements. For example, Method 1: When the shaft hole detection member 2 is inserted into the impeller shaft hole 104, the hub 101 of the impeller body 10 is kept at a certain distance from the plane on the flatness detection structure 1. The size of this distance can be adjusted according to the tolerable error of the actual design. At this time, rotate the impeller body 10. If the hub 101 does not contact the plane on the flatness detection structure 1, it means that the flatness of the hub 101 meets the production requirements. If the hub 101 contacts the plane on the flatness detection structure 1, it means that the flatness of the hub 101 is unqualified; Method 2: When the shaft hole detection member 2 is inserted into the impeller shaft hole 104, the hub 101 of the impeller body 10 is made to contact the plane on the flatness detection structure 1. If the hub 101 can fit with the plane on the flatness detection structure 1, it means that the flatness of the hub 101 meets the production requirements, otherwise it means that the flatness of the hub 101 is unqualified.

[0040] In the above Method 1, when the shaft hole detection member 2 is inserted into the impeller shaft hole 104, the hub 101 of the impeller body 10 is kept at a certain distance from the plane on the flatness detection structure 1, and this distance can be realized in various ways.

[0041] As an optional example, as Figure 1 and Figure 2 shown, the impeller detection device further includes at least one first positioning member 3, and the first positioning member 3 is used to position the impeller to be measured on the shaft hole detection member 2.

[0042] Optionally, the first positioning member 3 may be a screw, the shaft hole detection member 2 is provided with a second assembly hole 21, the central axis 103 of the impeller body 10 is provided with a first assembly hole 105, and the first assembly hole 105 is adapted to the second assembly hole 21. When it is necessary to detect the flatness of the hub 101, the impeller body 10 is sleeved on the shaft hole detection member 2, the shaft hole detection member 2 is inserted into the impeller shaft hole 104, the first assembly hole 105 is aligned with the second assembly hole 21, the first positioning member 3 passes through the first assembly hole 105 and the second assembly hole 21, and the impeller body 10 is positioned on the shaft hole detection member 2, and at the same time, the hub 101 of the impeller body 10 is spaced a certain distance from the plane on the flatness detection structure 1. If the hub 101 does not contact the plane on the flatness detection structure 1, it means that the flatness of the hub 101 meets the production requirements. On the other hand, during this process, it is also possible to verify whether the central axis 103 of the impeller body 10 can be stably and reliably connected to the first positioning member 3, and then verify whether the central axis 103 can be connected and positioned with the output end of the external driving device, thereby improving the stability and reliability of the connection between the two.

[0043] As another optional example, the shaft hole detection member 2 may be radially protruding to form a convex ring, and when the impeller body 10 is sleeved on the shaft hole detection member 2, the convex ring may abut against the impeller body 10 to axially position the impeller body 10 on the shaft hole detection member 2. The axial length of the convex ring may be adjusted according to the tolerable error of the actual design.

[0044] The shape and size of the shaft hole detection member 2 can be matched with the shape and size of the impeller shaft hole 104 of the impeller body 10, and the size of the impeller shaft hole 104 is slightly larger than the size of the shaft hole detection member 2. In terms of shape, for example, the impeller shaft hole 104 can be in the shape of a circular shaft, and the shaft hole detection member 2 is correspondingly in the shape of a circular shaft.

[0045] When it is necessary to detect whether the impeller shaft hole 104 of the impeller body 10 meets the production requirements, it can be determined based on the difficulty of inserting the shaft hole detection component 2 into the impeller shaft hole 104 to determine whether the impeller shaft hole 104 of the impeller body 10 is qualified.

[0046] Please refer to Figure 1 , Figure 3 and Figure 5 The detection plate axial hole 41 opened on the verticality detection plate 4 is used for the central axis 103 of the impeller body 10 to pass through, and the multiple radially extending blade detection grooves 42 opened on the verticality detection plate 4 are used for the blades 102 of the impeller body 10 to pass through, so as to detect the verticality of the blades 102.

[0047] Among them, the number and positions of the blade detection grooves 42 on the perpendicularity detection disk 4 correspond to the number and positions of the blades 102 on the impeller body 10. The shape and size of the blade detection grooves 42 are adapted to the shape and size of the blades 102, and the size of the blade detection grooves 42 is slightly larger than the size of the blades 102. The blade detection grooves 42 can be circumferentially and evenly distributed around the detection disk shaft hole 41.

[0048] As Figure 5 shown in [reference], when it is necessary to detect the perpendicularity of the blade 102, first sleuth the impeller body 10 on the shaft hole detection member 2, insert the shaft hole detection member 2 into the impeller shaft hole 104, and then sleuth the perpendicularity detection disk 4 on the impeller body 10. The central axis 103 of the impeller body 10 passes through the detection disk shaft hole 41 of the perpendicularity detection disk 4, and the blades 102 of the impeller body 10 correspondingly pass through the blade detection grooves 42. During this process, the blades 102 correspond to the blade detection grooves 42 one by one, and the blade detection grooves 42 move relative to the blades 102. If the perpendicularity detection disk 4 does not contact the blade 102 during the movement, it indicates that the perpendicularity of the blades 102 of the impeller body 10 meets the production requirements. If the perpendicularity detection disk 4 contacts the blade 102 during the movement, it indicates that the perpendicularity of the blades 102 of the impeller body 10 is unqualified.

[0049] On the one hand, the perpendicularity detection disk 4 can be positioned through the central axis 103 of the impeller body 10, and the operation and installation are simple and convenient. On the other hand, the perpendicularity detection disk 4 can detect the perpendicularity of multiple blades 102 at the same time, thereby improving the detection efficiency.

[0050] In some alternative embodiments, a plurality of lightweight holes 43 may be formed on the perpendicularity detection disk 4. The lightweight holes 43 are used for weight reduction, that is, to reduce the weight of the perpendicularity detection disk 4, making the perpendicularity detection disk 4 lighter and more convenient for the detection personnel to use the perpendicularity detection disk 4, and more labor-saving and convenient. On the other hand, it can also reduce the usage amount of the raw materials of the perpendicularity detection disk 4 and save costs.

[0051] The number and shape of the lightweight holes 43 can be arbitrary. As an example, the lightweight holes 43 can be arranged at intervals with the blade detection grooves 42 and are circumferentially distributed on the perpendicularity detection disk 4 as a whole. With such an arrangement, the lightweight holes 43 are more evenly distributed on the perpendicularity detection disk 4, that is, the overall mass distribution of the perpendicularity detection disk 4 can be made more uniform, and thus it is more convenient for the detection personnel to use the perpendicularity detection disk 4.

[0052] In some alternative embodiments, the impeller detection device further includes an outer edge detection member 5, and the outer edge detection member 5 is erected on the plane of the flatness detection structure 1. The outer edge detection member 5 is used to detect the outer contour of the impeller body 10.

[0053] The outer edge detection member 5 can be, but is not limited to, rod-shaped or sheet-shaped. The height of the outer edge detection member 5 is equal to or slightly greater than the height of the impeller body 10, and the distance between the outer edge detection member 5 and the shaft hole detection member 2 can be adjusted according to the radius of the impeller body 10.

[0054] As Figure 5 As shown in the figure, when it is necessary to detect the outer contour of the impeller body 10, the impeller body 10 is sleeved on the shaft hole detection member 2, and the shaft hole detection member 2 is inserted into the impeller shaft hole 104. When the impeller body 10 is rotated, if the impeller body 10 does not contact the shaft hole detection member 2, it means that the outer contour of the impeller body 10 meets the production requirements; if the impeller body 10 contacts the shaft hole detection member 2, it means that the outer contour of the impeller body 10 is unqualified.

[0055] The method for the outer edge detection member 5 to detect the outer contour of the impeller body 10 is simple and convenient. It uses a line to represent a surface and completes the detection of the outer contour degree through the rotation of the impeller body 10. On the other hand, during the process of rotating the impeller body 10, not only is it detected whether the outer contour degree of the impeller body 10 meets the requirements, but also whether the flatness of the hub 101 meets the requirements, which simplifies the operation steps and improves the detection efficiency.

[0056] In some alternative embodiments, the impeller detection device further includes a height detection member 6. The height detection member 6 is arranged on the outer edge detection member 5 and is located above the flatness detection structure 1. The height detection member 6 is used to detect whether the height of the impeller body 10 meets the production requirements. The distance between the height detection member 6 and the upper plane of the flatness detection structure 1 is set according to the height of the impeller body 10.

[0057] The height detection member 6 and the outer edge detection member 5 can be set to be detachably connected. The height detection member 6 can be, but is not limited to, rod-shaped or sheet-shaped.

[0058] In some alternative embodiments, a plug hole 51 is formed at the top of the outer edge detection member 5, and a plug end 61 matching the plug hole 51 is formed on the height detection member 6. The plug end 61 is inserted into the plug hole 51 to achieve the detachable connection between the height detection member 6 and the outer edge detection member 5.

[0059] As Figure 5 As shown in the figure, when it is necessary to detect the height of the impeller body 10, the impeller body 10 is sleeved on the shaft hole detection member 2, and the shaft hole detection member 2 is inserted into the impeller shaft hole 104. When the impeller body 10 is rotated, if the impeller body 10 does not contact the height detection member 6, it means that the height of the impeller body 10 meets the production requirements; if the impeller body 10 does not contact the height detection member 6, it means that the height of the impeller body 10 is unqualified.

[0060] On the other hand, in the process of rotating the impeller body 10, not only is it detected whether the height of the impeller body 10 meets the production requirements, but also whether the outer contour degree of the impeller body 10 and the flatness of the hub 101 meet the requirements, which simplifies the operation steps and improves the detection efficiency.

[0061] In some alternative embodiments, in order to prevent the height detection member 6 from obstructing the impeller body 10 from being sleeved into the shaft hole detection member 2 when installing the impeller body 10, the outer edge detection member 5 and the flatness detection structure 1 can be arranged to be rotatably connected. In this way, before installing the impeller body 10, the outer edge detection member 5 can be rotated to drive the height detection member 6 to rotate, and the height detection member 6 can be moved away to facilitate the impeller body 10 to be sleeved into the shaft hole detection member 2, making the detection process smoother and more convenient and improving the detection efficiency.

[0062] There can be various ways of rotatably connecting the outer edge detection member 5 and the flatness detection structure 1.

[0063] As an example, the outer edge detection member 5 and the flatness detection structure 1 can be connected by arranging a self-lubricating bushing.

[0064] As another example, please refer to Figure 1 and Figure 4 , a second bearing seat 72 is arranged on the flatness detection structure 1, a second bearing 74 is arranged in the second bearing seat 72, and one end of the outer edge detection member 5 is inserted into the second bearing 74. The outer edge detection member 5 and the flatness detection structure 1 are rotatably connected through the second bearing 74, effectively reducing the rotational friction and improving the rotational smoothness.

[0065] Specifically, a second seat hole 12 is formed on the flatness detection structure 1, the second bearing seat 72 is installed in the second seat hole 12, and the second bearing seat 72 and the flatness detection structure 1 can be relatively fixed by arranging a second fastener 92. The second fastener 92 can be but is not limited to screws, pins, etc. One end of the outer edge detection member 5 has a reduced diameter to form a second rotation connection end 52, and the second rotation connection end 52 is inserted into the inner ring of the second bearing seat 72, and the outer ring of the second bearing 74 is connected to the second bearing seat 72.

[0066] In some alternative embodiments, in order to facilitate the smooth rotation of the impeller body 10 for detection, please refer to Figure 1 and Figure 4 , the shaft hole detection member 2 and the flatness detection structure 1 are rotatably connected.

[0067] There can be various ways of rotatably connecting the shaft hole detection member 2 and the flatness detection structure 1.

[0068] As an example, the shaft hole detection member 2 and the flatness detection structure 1 can be connected by arranging a self-lubricating bushing.

[0069] As another example, please refer to Figure 1 and Figure 4 together. A first bearing seat 71 is provided on the flatness detection structure 1, a first bearing 73 is provided in the first bearing seat 71, and one end of the shaft hole detection member 2 is inserted into the first bearing 73. The shaft hole detection member 2 and the flatness detection structure 1 are rotationally connected through the first bearing 73, effectively reducing the rotational friction and improving the rotational smoothness, making it more smooth and fast for the tester to rotate the impeller body 10.

[0070] Specifically, a first seat hole 11 is formed on the flatness detection structure 1, the first bearing seat 71 is installed in the first seat hole 11, and the first bearing seat 71 and the flatness detection structure 1 can be relatively fixed by setting a first fastener 91. The first fastener 91 can be, but is not limited to, screws, pins, etc. One end of the shaft hole detection member 2 has a reduced diameter to form a first rotation connection end 22, and the first rotation connection end 22 is inserted into the inner ring of the first bearing 73, and the outer ring of the first bearing 73 is connected to the first bearing seat 71.

[0071] Optionally, please refer to Figure 1 and Figure 4 together. To prevent the axial dislocation of the shaft hole detection member 2 when rotating the impeller body 10, the shaft hole detection member 2 can be axially limited on the flatness detection structure 1, making the impeller detection device more stable and reliable. For example, a limiting groove 23 is formed at one end of the shaft hole detection member 2 inserted into the first bearing 73. After the limiting groove 23 passes through the first bearing 73, axial limitation is carried out by setting a limiting member such as a snap ring 75 in the limiting groove 23. The snap ring 75 is used to abut against the first bearing 73 to prevent the shaft hole detection member 2 from being axially displaced when rotating the impeller body 10.

[0072] In some alternative embodiments, as shown in Figure 1 , the impeller detection device further includes a plurality of buffer foot pads 8. The buffer foot pads 8 are provided at the bottom of the flatness detection structure 1 for shock absorption. The buffer foot pads 8 can be connected to the buffer foot pads 8 by, but are not limited to, snap connection, screw connection, etc. The buffer foot pads 8 can be of, but are not limited to, types such as silicone buffer foot pads, rubber buffer foot pads, etc. In this way, the buffer foot pads 8 can play a role in buffering and shock absorption, thus being more conducive to the tester using the impeller detection device more stably.

Although the present application has been disclosed above in the preferred embodiments, it is not intended to limit the present application.
