Description

Technical Field

[0001] This utility model belongs to the field of intelligent lawnmower technology, specifically relating to a tooling for installing the wheels of an intelligent lawnmower. Background Technology

[0002] In the current assembly process of lawnmowers, the wheels are mostly assembled manually directly to the axle. This method has the following drawbacks: insufficient positioning accuracy: during manual assembly, the axle and the hole position of the wheels are prone to misalignment, resulting in bearing damage or increased concentricity deviation; low assembly efficiency, and reliance on skilled workers, leading to high training costs. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling for installing a walking wheel. By combining the main positioning seat and the auxiliary positioning seat, the wheel axle is limited and clamped in multiple dimensions using horizontal and vertical grooves. This keeps the wheel axle in a fixed position and posture during the assembly process, making it easier to accurately press the walking wheel onto the wheel axle, reducing the misalignment between the wheel axle and the hole position of the walking wheel, improving assembly efficiency, and reducing reliance on skilled workers.

[0004] This utility model provides a tooling for installing the walking wheels of an intelligent lawnmower, comprising: a main positioning seat having a side wall formed around a perimeter, a notch on the side wall, a circular groove inside the main positioning seat, and a rectangular groove at the bottom of the circular groove; and an auxiliary positioning seat having a base and an extension, wherein the base is accommodated in the rectangular groove, a wheel axle groove is provided on the base for accommodating a wheel axle, and the extension is shaped to fit the notch.

[0005] Furthermore, after the auxiliary positioning seat fills the gap, the sidewall of the main positioning seat and the extension form a closed ring.

[0006] Furthermore, the width of the rectangular groove is the same as the width of the base, the length of the rectangular groove is the same as the length of the base, the rectangular groove extends towards the bottom surface of the main positioning seat, and the height of the side wall is the same as the height of the extension.

[0007] Furthermore, the wheel axle groove includes a horizontal groove and a vertical groove, wherein the horizontal groove is located in the middle of the base and extends along the length direction of the base, and the vertical groove is located on the extension and extends along the height direction of the extension. The horizontal groove and the vertical groove are perpendicular to each other, and the horizontal groove and the vertical groove are connected at their ends.

[0008] Furthermore, the vertical groove provides radial positioning for the cylindrical section of the wheel axle, and the horizontal groove provides axial and rotational limiting for the planar section of the wheel axle.

[0009] Furthermore, the auxiliary positioning seat is replaceable.

[0010] The beneficial effects of this utility model are: (1) The main positioning seat and the auxiliary positioning seat cooperate to radially position the cylindrical section of the wheel axle by the vertical groove and axially and rotationally limit the planar section of the wheel axle by the horizontal groove, thereby realizing multi-dimensional limiting and clamping of the three degrees of freedom of the wheel axle, so that the position and posture of the wheel axle are fixed when the walking wheel is pressed, which facilitates the alignment of the walking wheel and the wheel axle hole and reduces the deviation caused by manual assembly. (2) Compared with manual adjustment of the wheel axle and the hole position of the traveling wheel, this tooling reduces the number of manual alignments, which helps to improve the assembly cycle and production efficiency. (3) The auxiliary positioning seat is replaceable. For different wheel axle diameters, only the auxiliary positioning seat corresponding to the wheel axle groove needs to be replaced, without replacing the entire tooling, which reduces tooling costs and the difficulty of changing the tooling.

Detailed Implementation

[0012] like Figure 1 As shown, the main positioning seat 10 has a side wall 11 formed around a perimeter. A notch 12 is provided on the side wall 11. A circular groove 13 is provided inside the main positioning seat 10, and a rectangular groove 14 is provided at the bottom of the circular groove 13. The circular groove 13 is an internal cavity formed by the side wall 11, and the rectangular groove 14 at its bottom is used to accommodate and position the base 21 of the auxiliary positioning seat 20. The circular groove 13 and the rectangular groove 14 together constitute the wheel axle positioning and support area of ​​the main positioning seat 10. The auxiliary positioning seat 20 has a base 21 and an extension 22. The base 21 is accommodated in the rectangular groove 14, and a wheel axle groove 30 is provided on the base to accommodate a wheel axle 40. The extension 22 is shaped to fit the notch 12.

[0013] like Figure 2 As shown, after the auxiliary positioning seat 20 fills the notch 12, the side wall 11 of the main positioning seat 10 and the extension 22 form a closed ring. The extension 22 and the notch 12 are shape-matched, meaning that their shapes are complementary and they abut each other through surface contact. After the auxiliary positioning seat 20 fills the notch 12, it together with the side wall 11 of the main positioning seat 10 forms a closed ring, restricting the displacement of the auxiliary positioning seat 20.

[0014] like Figure 3 As shown, the width of the rectangular groove 14 is the same as the width of the base 21, and the length of the rectangular groove 14 is the same as the length of the base 21. The rectangular groove 14 extends towards the bottom surface of the main positioning seat 10, and the height of the side wall 11 is the same as the height of the extension 22. The rectangular groove 14 provides three-dimensional limiting in the width, length, and depth directions, so that the auxiliary positioning seat 20 is stably installed. After installation, the positioning stability is improved through surface contact.

[0015] like Figure 4 As shown, the wheel axle groove 30 includes a horizontal groove 31 and a vertical groove 32. The horizontal groove 31 is located in the middle of the base 21, symmetrically arranged about the center line of the base 21, and extends along the length direction of the base 21. The vertical groove is located on the extension 22 and extends along the height direction of the extension 22. The horizontal groove 31 and the vertical groove 32 are perpendicular to each other and are connected at their ends. The vertical groove 32 is used for radial positioning of the cylindrical section of the wheel axle 40, and the horizontal groove 31 is used for axial and rotational limiting of the planar section of the wheel axle 40. That is, the vertical groove 32 achieves radial positioning, and the horizontal groove 31 achieves axial and rotational limiting. Together, they constitute multi-dimensional limiting and clamping of the wheel axle 40 in the radial, axial, and circumferential degrees of freedom.

[0016] like Figure 5 As shown, the auxiliary positioning seat 20 is replaceable to match axles 40 of different diameters. Specifically, its base 21 is accommodated with the same width and length as the rectangular groove 14 to achieve shape-fit positioning. For axles 40 of different diameters, the auxiliary positioning seat 20 with the corresponding axle groove 30 can be replaced. After replacement, the shape fit between the rectangular groove 14 and the base 21 ensures consistent positioning, thereby reducing production costs and facilitating model changeover.

[0017] The method of using this utility model tooling includes the following steps: Step 1: Fix the main positioning seat 10 to the worktable; Step 2: According to the diameter of the axle 40, select an auxiliary positioning seat 20 with a corresponding axle groove 30, and accommodate its base 21 in the rectangular groove 14, so that the extension 22 fills the gap 12 and forms a closed ring with the side wall 11. Step 3: Place the axle 40 in the axle groove 30, so that its cylindrical section is inserted into the vertical groove 32 and its planar section is inserted into the horizontal groove 31. The horizontal groove 31 and the vertical groove 32 limit the axle 40 radially, axially and rotationally, so that the axle 40 maintains a fixed position and posture during assembly. Step 4: Assemble the traveling wheels onto the wheel axle 40 that has been limited by the tooling. Since the position and orientation of the wheel axle 40 are determined by the tooling, it is easy to align the traveling wheels with the holes of the wheel axle 40. Step 5: Press-fit the bearings to make the traveling wheel and the axle 40 concentric and fixed. Step 6: Remove the assembled walking wheel assembly.

[0018] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
