Description

Technical Field

[0001] The present application relates to the technical field of lawn mowers, and particularly relates to an assembly tool for the power and guide seat components of a lawn mower. Background Art

[0002] Currently, for fuel-powered riding lawn mowers, the CVT (Continuously Variable Transmission) mechanism needs to be coaxially arranged with the engine. If they are not coaxially arranged, the drive belt for transmitting power between the two will be severely worn.

[0003] The CVT mechanism needs to be fixedly installed through a guide seat component, so the position of the guide seat component relative to the engine needs to be more precise. When the guide seat component can be coaxially arranged with the output shaft of the engine, the CTV mechanism can naturally be coaxially arranged with the output shaft of the engine.

[0004] Therefore, aiming at the above technical problems, how to ensure that the guide seat component is coaxially arranged with the output shaft of the engine is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of the present application is to provide an assembly tool for the power and guide seat components of a lawn mower, which can realize the coaxial arrangement of the guide seat component and the output shaft of the engine.

[0006] To achieve the above purpose, the present application provides an assembly tool for the power and guide seat components of a lawn mower, including a tooling body. A slot hole matching the diameter of the output shaft of the engine is provided in the middle of the tooling body to radially limit the output shaft of the engine. Limiting components for radially limiting the guide seat component are provided at both ends of the tooling body, and the limiting components are used to coaxially arrange the guide seat component and the slot hole.

[0007] Preferably, the limiting components include a plurality of positioning holes provided on the tooling body and a plurality of positioning columns provided on the guide seat component. The positioning columns correspond to the positioning holes one by one and are inserted, and the diameter of the positioning column matches the inner diameter of the positioning hole.

[0008] Preferably, the plurality of positioning holes are distributed on a distribution circle with the axis of the slot hole as the center, and the positioning columns are detachably arranged on the guide seat component.

[0009] Preferably, the engine and the guide seat component are respectively fixedly arranged on both sides of a frame fixing plate. A through hole for the output shaft of the engine to pass through is provided on the frame fixing plate, and the tooling body and the guide seat component are located on the same side of the frame fixing plate.

[0010] Preferably, a plurality of limiting protrusions are provided on one side of the tooling main body facing the vehicle frame fixing plate, and limiting grooves corresponding to the limiting protrusions are provided on the vehicle frame fixing plate. When the limiting protrusions are engaged with the limiting grooves, the tooling main body abuts against the vehicle frame fixing plate.

[0011] Preferably, a limiting bump is provided on one side of the tooling main body facing the vehicle frame fixing plate, the limiting protrusion is provided on the limiting bump, and the limiting bump abuts against the vehicle frame fixing plate.

[0012] Preferably, the end of the limiting protrusion has a frustum section and a columnar section at the bottom. The top diameter of the frustum section is small and the bottom diameter is large. The bottom diameter of the frustum section is the same as the diameter of the columnar section, and the columnar section can be inserted into the limiting groove.

[0013] Preferably, the middle of the guide seat component is hollowed out, and the limiting bump passes through the hollowed-out part in the middle of the guide seat component and abuts against the vehicle frame fixing plate.

[0014] Preferably, the guide seat component and the engine are fixed to the vehicle frame fixing plate by bolts.

[0015] Compared with the above background technology, the tooling of the present application can be matched with the output shaft of the engine through the slot hole, so that the output shaft of the engine and the tooling main body remain relatively stationary in the radial direction. The tooling is also limitedly connected to the guide seat component through the limiting component, so as to radially limit the guide seat component. At the same time, when the limiting component connects the guide seat component and the tooling main body, it can also make the guide seat component coaxial with the slot hole, so that the guide seat component is coaxial with the output shaft in the slot hole. On this basis, no matter how the position of the engine or the guide seat component changes, the engine and the guide seat component can move synchronously, ensuring that when assembling the engine or the guide seat component, even if there is a certain deviation, the guide seat component can still be coaxial with the output shaft of the engine.

In addition, "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In order to enable those skilled in the art of this technical field to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0025] Such as Figure 1As shown, in this embodiment, a power and guide seat component 2 assembly tooling for a lawn mower is provided, which includes a tooling main body 1. A slot hole 11 is formed in the middle of the tooling main body 1. The slot hole 11 can be a through hole or a blind hole, as long as the output shaft 41 of the engine 4 can extend into the slot hole 11. It should be noted that the diameter of the slot hole 11 on the tooling main body 1 should match the diameter of the output shaft 41, so that after the output shaft 41 is inserted into the slot hole 11, the tooling main body 1 and the output shaft 41 can remain relatively stationary in the radial direction. Of course, in the actual machining process, due to machining accuracy reasons, if the diameter of the output shaft 41 and the diameter of the slot hole 11 are exactly the same, there may be a problem that the two cannot be inserted. Therefore, the diameter of the slot hole 11 can be slightly larger than the diameter of the output shaft 41 to facilitate the smooth insertion of the output shaft 41 into the slot hole 11, but it should be ensured that the two can remain relatively stationary in the radial direction.

[0026] Limit components are provided at both ends of the tooling main body 1. The tooling main body 1 is limit-connected to the guide seat component 2 through the limit components, so that the tooling main body 1 and the guide seat component 2 remain relatively stationary in the radial direction. In addition, when the limit components connect the tooling main body 1 and the guide seat component 2, the guide seat component 2 can also be coaxially arranged with the slot hole 11, so that the guide seat component 2 is coaxially arranged with the output shaft 41.

[0027] It should be noted that to ensure that the guide seat component 2 is coaxially arranged with the slot hole 11, when the limit components connect the two, the slot hole 11 of the tooling main body 1 can be machined with the central axis of the guide seat component 2 as the machining center. As for the specific machining method, it will not be elaborated here and can refer to the prior art.

[0028] Based on the above embodiments, the tooling of the present application can match the slot hole 11 with the output shaft 41 of the engine 4, so that the output shaft 41 of the engine 4 and the tooling main body 1 remain relatively stationary in the radial direction. The tooling is also limit-connected to the guide seat component 2 through the limit components, so as to radially limit the guide seat component 2. At the same time, when the limit components connect the guide seat component 2 and the tooling main body 1, the guide seat component 2 can also be coaxially arranged with the slot hole 11, so that the guide seat component 2 is coaxially arranged with the output shaft 41 in the slot hole 11. On this basis, no matter how the position of the engine 4 or the guide seat component 2 changes, the engine 4 and the guide seat component 2 can move synchronously, ensuring that when assembling the engine 4 or the guide seat component 2, even if there is a certain offset, the guide seat component 2 can still be coaxially arranged with the output shaft 41 of the engine 4.

[0029] Among them, there are various ways to set the limit components, as long as the guide seat component 2 and the tooling main body 1 remain relatively stationary in the radial direction. For example, methods such as clamping, plugging, and threaded connection are used, which will not be elaborated one by one here and all fall within the protection scope of the present application.

[0030] However, the present application realizes the limiting function of the limiting component in a plug-in manner. Specifically, the limiting component includes a plurality of positioning holes 12 provided on the tooling main body 1. Please refer to Figure 3 , the number of the positioning holes 12 is at least two. Correspondingly, positioning columns 5 inserted into the positioning holes 12 are provided on the guide seat component 2. The positioning columns 5 correspond to the positioning holes 12 one by one and are inserted. The axes of the positioning holes 12 and the positioning columns 5 are consistent with the axis of the guide seat component 2, and the diameter of the positioning column 5 matches the inner diameter of the positioning hole 12. The cooperation of at least two positioning positions and the positioning holes 12 can keep the guide seat component 2 and the tooling main body 1 stationary in the radial direction. Of course, for the diameters of the positioning hole 12 and the positioning column 5, the cooperation form of the output shaft 41 and the slot hole 11 can be referred to. In an ideal situation, the diameters of the positioning hole 12 and the positioning column 5 are the same. However, in the actual processing process, the diameter of the positioning hole 12 should be slightly larger than the diameter of the positioning position, but it is necessary to ensure that the positioning hole 12 and the positioning column 5 will not deviate in the radial direction, which will not be elaborated here.

[0031] In some embodiments, the number of the positioning holes 12 and the positioning columns 5 is four. Two positioning holes 12 are distributed at one end of the tooling main body 1, and the other two positioning holes 12 are distributed at the other end of the tooling main body 1. On this basis, since the guide seat component 2 is integrally annular, the four positioning holes 12 can be distributed on a distribution circle centered on the axis of the slot hole 11, so as to form four regularly distributed positioning holes 12 and reduce the processing difficulty of the positioning holes 12. Of course, there are no excessive restrictions on the specific setting method of the positioning holes 12 here. The positioning holes 12 can also be set in an irregular distribution manner, as long as it is ensured that the positioning holes 12 can cooperate with the positioning columns 5 on the guide seat component 2.

[0032] In addition, through the cooperation of the positioning column 5 and the positioning hole 12, the tooling body and the guide seat component 2 can also be detachably connected. Specifically, both the positioning column 5 and the positioning hole 12 are arranged along the axis of the guide seat component 2. Therefore, when the positioning column 5 and the positioning hole 12 are aligned, only axial movement is required to realize the insertion of the positioning column 5 and the positioning hole 12, and the radial limit of the guide seat component 2 and the tooling body is completed. However, in the axial direction, the two can slide relative to each other. Therefore, when the tooling body is not needed, only the tooling body needs to be axially separated from the positioning column 5 to realize the detachable connection between the tooling body and the guide seat component 2, providing conditions for the guide seat component 2 to connect the CVT mechanism.

[0033] The presence of the positioning post 5 may also affect the assembly of the CVT mechanism and the guide seat component 2. Therefore, the positioning post 5 can also be connected to the guide seat component 2 in a detachable connection manner, such as threaded connection, plug-in connection, etc. Threaded connection will not be elaborated here, that is, the detachable connection is achieved through the thread. The plug-in connection method is to set a point with a jack on the guide seat component 2, and insert the positioning post 5 into the jack. Of course, in order to make the positioning post 5 have higher stability after being connected to the guide seat component 2 and improve the connection reliability between the guide seat component 2 and the tooling body, the positioning post 5 can be in interference fit with the jack. Without external force intervention, the positioning post 5 can be stably inserted into the jack, and the positioning post 5 can also be pulled out by external force to achieve the detachable connection between the positioning post 5 and the guide seat component 2.

[0034] After the output shaft 41 of the engine 4 is coaxially arranged with the guide seat component 2 through the tooling main body 1, the engine 4 and the guide seat component 2 can be respectively fixed on both sides of the frame fixing plate 3. The frame fixing plate 3 is a component on the lawn mower, which is used to play a role in fixing and supporting the engine 4 and the CVT mechanism. A through hole 31 for the output shaft 41 of the engine 4 to pass through is opened on the frame fixing plate 3, and the diameter of the through hole 31 is larger than the diameter of the output shaft 41. As Figure 2 shown, it is convenient to adjust the fixing positions of the engine 4 and the guide seat component 2, so that the engine 4 and the guide seat component 2 can be adapted to the screw holes on the frame fixing plate 3.

[0035] During the operation process, first place the engine 4 on the first side of the frame fixing plate 3, and the guide seat component 2 is located on the second side of the frame fixing plate 3. The output shaft 41 of the engine 4 passes through the through hole 31 to reach the second side of the frame fixing plate 3. Align the slot hole 11 of the tooling main body 1 with the output shaft 41, and align the positioning hole 12 with the positioning post 5. Assemble the tooling main body 1 on the second side of the frame fixing plate 3. After the assembly is completed, it can be ensured that the guide seat component 2 and the output shaft 41 are coaxial; thereafter, fix the guide seat component 2 and the engine 4 to the frame fixing plate 3 respectively. During the fixing process, due to the presence of the tooling body, the guide seat component 2 always remains coaxial with the output shaft 41, preventing situations such as deviation.

[0036] In addition, in order to make the tooling main body 1, the engine 4, and the guide seat component 2 be assembled on the frame fixing plate 3 more conveniently, several limiting protrusions 14 can be provided on the side of the tooling main body 1 facing the frame fixing plate 3. Please refer to Figure 4 The frame fixing plate 3 is provided with limiting grooves corresponding to and cooperating with the limiting protrusions 14. Through the cooperation of the limiting protrusions 14 and the limiting grooves, the tooling main body 1 can be quickly assembled in place on the frame fixing plate 3. Correspondingly, the guide seat component 2 and the engine 4 can also be driven to be assembled in place, so that the guide seat component 2 and the engine 4 can be quickly assembled with the frame fixing plate 3.

[0037] To improve the stability of the tooling main body 1 during use, when the limiting protrusion 14 cooperates with the limiting groove, the tooling main body 1 can abut against the vehicle frame fixing plate 3, so that the tooling main body 1 has a stable supporting surface, that is, the plate surface of the vehicle frame fixing plate 3; further, a limiting convex block 13 is provided on the side of the tooling main body 1 facing the vehicle frame fixing plate 3. Please refer to Figure 4 , the limiting protrusion 14 is arranged on the limiting convex block 13. Therefore, when the limiting protrusion 14 cooperates with the limiting groove, the end face of the limiting convex block 13 can abut against the plate surface of the vehicle frame fixing plate 3.

[0038] In some embodiments, the end of the limiting protrusion 14 has a frustum section, and the bottom has a columnar section, that is, one end of the limiting protrusion 14 close to the limiting convex block 13 has a columnar section. The frustum section has the characteristics of a small top diameter and a large bottom diameter, which is convenient for the limiting protrusion 14 to enter the limiting groove smoothly and quickly, improving the assembly efficiency. And the bottom diameter of the frustum section is the same as the diameter of the columnar section, and the diameter of the columnar section is the same as the diameter of the limiting groove, so that the tooling main body 1 can be fixedly arranged relative to the vehicle frame fixing plate 3 in the radial direction; of course, the diameter of the columnar section can also be smaller than the diameter of the limiting groove, so that the tooling main body 1 has a certain adjustable space on the vehicle frame fixing plate 3, which is convenient for fine-tuning the positions of the guide seat component 2 and the engine 4 relative to the vehicle frame fixing plate 3.

[0039] In addition, the guide seat component 2 is provided with a hollow in the middle, that is, the guide seat component 2 is an annular structure, and the limiting convex block 13 can pass through the hollow position in the middle of the guide seat component 2 and abut against the price verification fixing plate. After the positions of the guide seat component 2 and the engine 4 are adjusted in place, the guide seat component 2 and the engine 4 can be fixed on the vehicle frame fixing plate 3 by tightening the fastening members. After the fixation is completed, the tooling main body 1 can be removed for the next operation.

It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
