Description

Technical Field

[0001] The utility model belongs to the technical field of detection fixtures, and in particular relates to an automatic detection fixture for a front wheel axle spring of a sweeper. Background Art

[0002] A robot vacuum, also known as an automatic sweeper, smart vacuum, or robot vacuum, is a type of smart home appliance that uses artificial intelligence to automatically clean floors. It typically uses a brushing and vacuuming method to collect debris into its own trash collection bin, completing the cleaning process. Generally speaking, any robot that performs sweeping, vacuuming, and mopping is also categorized as a robot vacuum.

[0003] like Figure 1 The figure shows the front axle of a robot vacuum. The curved axle is designed to accommodate the robot's overall structure and movement. This helps the robot better adapt to various terrains and reduces the risk of collisions and jams. Specifically, this design is based on the following considerations:

[0004] 1. Adaptability to terrain changes: The curved front axle allows the robot to better adapt to different ground conditions, such as carpets, floors, and terrains with different materials and heights. This design can reduce the risk of bumps and jams during the robot's driving;

[0005] 2. Improved flexibility: The curved front axle design makes the robot more flexible when turning, enabling it to better cope with various obstacles and corners in the home, reducing blind spots in cleaning;

[0006] 3. Reduce collisions: The curved front axle design can reduce collisions between the robot and obstacles such as furniture and walls, protect the robot and furniture from damage, and optimize the motion trajectory; therefore, through the curved front axle design, the robot can complete various motion trajectories more smoothly, improving cleaning efficiency and effectiveness.

[0007] like Figure 1 As shown, the curved front axle is integrally formed using a spring making machine, and therefore can also be called a front axle spring. It includes a first front axle rod, a second front axle rod, a third front axle rod, a fourth front axle rod, a first transition portion, a second transition portion, a third transition portion, a first clamping portion, and a second clamping portion. The second front axle rod is integrally connected to one end of the first front axle rod, and the second front axle rod is perpendicular to the first front axle rod; the third front axle rod is integrally connected to the end of the second front axle rod away from the first front axle rod, and the third front axle rod is perpendicular to the second front axle rod. The first, second, and third front axles are located in the same plane.

[0008] The first transition portion transitionally connects the first front wheel axle and the second front wheel axle, and the second transition portion transitionally connects the second front wheel axle and the third front wheel axle. The arrangement of the first transition portion and the second transition portion avoids sharp corners at the connection, avoids scratches on workers during use and installation, and avoids stress concentration that may cause the front wheel axle to break during use.

[0009] The fourth front wheel shaft is obliquely connected to the end of the third front wheel shaft away from the second front wheel shaft, and the fourth front wheel shaft is connected to the third front wheel shaft through a third transition portion, and the third transition portion has the same function as the second transition portion.

[0010] The first clamping portion is integrally provided at an end of the first front wheel shaft near the second front wheel shaft, and the second clamping portion is integrally provided at an end of the fourth front wheel shaft near the third front wheel shaft. The first clamping portion and the second clamping portion are stamped on the first and fourth front wheel shafts using a stamping process. The first clamping portion and the second clamping portion are used to stop and limit the bearings inserted into the first and fourth front wheel shafts.

[0011] After the front wheel axle is processed, the inclination angle of the fourth front wheel axle rod on the front wheel axle needs to be tested to screen out unqualified products. The existing testing method usually uses an angle measuring instrument for testing. However, due to the irregularity of the front wheel axle, the front wheel axle placed on the testing plane is easy to rotate during testing, affecting the accuracy of the measurement results, and therefore it is impossible to accurately screen out unqualified products.

[0037] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0038] like Figure 2-4 The figure shows the structure of the automatic detection tool for the front wheel axle spring of the sweeper of the utility model. The detection tool is usually used to detect Figure 1 The front axle in the Figure 1 As shown, the front wheel axle is made in one piece by a spring making machine, so the front wheel axle can also be called a front wheel axle spring, which includes a first front wheel axle rod 30, a second front wheel axle rod 31, a third front wheel axle rod 32, a fourth front wheel axle rod 33, a first transition portion 34, a second transition portion 35, a third transition portion 36, a first clamping portion 37 and a second clamping portion 38.

[0039] The second front wheel shaft 31 is integrally connected to one end of the first front wheel shaft 30, and the second front wheel shaft 31 is perpendicular to the first front wheel shaft 30. The third front wheel shaft 32 is integrally connected to the end of the second front wheel shaft 31 away from the first front wheel shaft 30, and the third front wheel shaft 32 is perpendicular to the second front wheel shaft 31. The first front wheel shaft 30, the second front wheel shaft 31, and the third front wheel shaft 32 are located in the same plane.

[0040] The first transition portion 34 transitionally connects the first front wheel axle 30 and the second front wheel axle 31, and the second transition portion 35 transitionally connects the second front wheel axle 31 and the third front wheel axle 32. The arrangement of the first transition portion 34 and the second transition portion 35 avoids sharp corners at the connection, avoids scratches on workers during use and installation, and avoids stress concentration that may cause the front wheel axle to break during use.

[0041] The fourth front wheel shaft 33 is obliquely connected to the end of the third front wheel shaft 32 away from the second front wheel shaft 31, and the fourth front wheel shaft 33 and the third front wheel shaft 32 are connected by a third transition portion 36. The third transition portion 36 and the second transition portion 35 have the same function.

[0042] The first clamping portion 37 is integrally provided at one end of the first front wheel shaft 30 near the second front wheel shaft 31, and the second clamping portion 38 is integrally provided at one end of the fourth front wheel shaft 33 near the third front wheel shaft 32. The first clamping portion 37 and the second clamping portion 38 are stamped on the first front wheel shaft 30 and the fourth front wheel shaft 33 through a stamping process. The first clamping portion 37 and the second clamping portion 38 are used to stop and limit the bearings inserted into the first front wheel shaft 30 and the fourth front wheel shaft 33.

[0043] like Figure 2-4 The figure shows the structure of the automatic detection tool for the front wheel axle spring of the sweeping machine of the utility model. The detection tool is usually used to detect Figure 1 Check whether the inclination angle of the fourth front wheel shaft rod 33 of the front wheel axle meets the requirements.

[0044] The jig plate 1 is a rectangular metal plate, and the inner plate 2 is fixed to the top of the jig plate 1 by screws. When the front wheel axle is tested, the "["-shaped structure formed by the first front wheel axle rod 30, the second front wheel axle rod 31 and the third front wheel axle rod 32 is stuck on the inner plate 2.

[0045] The first outer clamping plate 3 is fixed to the top of the jig plate 1 by screw fastening and is located on one side of the inner clamping plate 2. A first clamping groove 6 is formed between the first outer clamping plate 3 and the inner clamping plate 2. When the front wheel axle is inspected, the first front wheel axle rod 30 of the front wheel axle is stuck in the first clamping groove 6, and the first outer clamping plate 3 is parallel to a short side of the inner clamping plate 2.

[0046] The height of the first outer plate 3 is equal to that of the inner plate 2, and the height of the first clamping groove 6 is equal to the diameter of the first front wheel shaft 30. When the first limiting plate 15 moves inward, it presses the first front wheel shaft 30 in the first clamping groove 6 to prevent the front wheel shaft from shaking and affecting the detection results.

[0047] The second outer splint 4 is fixed to the top of the jig plate 1 by screw fastening and is located on one side of the inner splint 2. A second clamping groove 7 is formed between the second outer splint 4 and the inner splint 2. When the front wheel axle is inspected, the second front wheel axle rod 31 of the front wheel axle is stuck in the second clamping groove 7. The second outer splint 4 is parallel to a long side of the inner splint 2, so the second outer splint 4 is perpendicular to the first outer splint 3.

[0048] The height of the second outer plate 4 is equal to that of the inner plate 2, and the height of the second clamping groove 7 is equal to the diameter of the second front wheel axle 31. When the second limiting plate 19 moves inward, it presses the second front wheel axle 31 in the second clamping groove 7 to prevent the front wheel axle from shaking and affecting the detection results.

[0049] The third outer plywood 5 is fixed to the top of the jig plate 1 by screw fastening and is located on one side of the inner plywood 2. A third clamping groove 8 is formed between the third outer plywood 5 and the inner plywood 2. When the front wheel axle is inspected, the third front wheel axle rod 32 of the front wheel axle is stuck in the third clamping groove 8. The third outer plywood 5 is parallel to the other short side of the inner plywood 2, so the third outer plywood 5 is perpendicular to the second outer plywood 4.

[0050] The height of the third outer clamping plate 5 is equal to that of the inner clamping plate 2, and the height of the third clamping groove 8 is equal to the diameter of the third front wheel shaft 32. Because the first and second front wheel shafts 30 and 31 of the front wheel axle are already pressed together by the first and second limiting plates 15 and 19, even if a corresponding pressing mechanism is not provided for the third front wheel shaft 32, the front wheel axle can still be prevented from shaking in the clamping groove.

[0051] At the same time, the width of the first clamping groove 6 is equal to the diameter of the first front wheel shaft 30 , the width of the second clamping groove 7 is equal to the diameter of the second front wheel shaft 31 , and the width of the third clamping groove 8 is equal to the diameter of the third front wheel shaft 32 .

[0052] like Figure 2-4 As shown, the inner plate 2 is provided with a first inner avoidance groove 9 and a second inner avoidance groove 10 on the side close to the second outer plate 4. The first inner avoidance groove 9 is used to avoid the first transition portion 34 of the front wheel axle, and the second inner avoidance groove 10 is used to avoid the second transition portion 35 of the front wheel axle. The first outer avoidance groove 11 is provided on the side close to the inner plate 2 of the first outer plate 3. The first outer avoidance groove 11 and the first inner avoidance groove 9 are used to avoid the first clamping portion 37 of the front wheel axle. The third outer plate 5 is provided with a second outer avoidance groove 12 on the side close to the inner plate 2. The second outer avoidance groove 12 is used to avoid the second clamping portion 38 of the front wheel axle.

[0053] The first limiting assembly is fixed to the top of the jig plate 1 and is used to press the first front wheel shaft 30 in the first clamping groove 6. The first limiting assembly includes a first slide rail 13, a first slider 14, a first limiting plate 15, and a first limiting post 16. The first slide rail 13 is fixed to the top of the jig plate 1 by screws and is arranged perpendicular to the first outer clamping plate 3. The first slider 14 is slidably mounted on the first slide rail 13.

[0054] The first stopper plate 15 is fixed to the top of the first slider 14, and the lower surface of the first stopper plate 15 is flush with the upper surface of the first outer clamping plate 3. Therefore, after the front wheel axle is placed in the clamping groove, when the operator pushes the first stopper plate 15 inward, the first stopper plate 15 moves in contact with the upper surfaces of the first outer clamping plate 3 and the inner clamping plate 2, thereby pressing the first front wheel axle rod 30 in the first clamping groove 6, preventing the front wheel axle from shaking in the clamping groove and affecting the detection results.

[0055] The first limiting column 16 is fixed on the top of the jig plate 1 and is located on the side of the first slide rail 13 away from the first outer clamping plate 3. The first limiting column 16 resists and limits the outward movement of the first limiting plate 15 to prevent the first limiting plate 15 from sliding outward and then slipping off the first slide rail 13.

[0056] The second limiting assembly is fixed to the top of the jig plate 1 and is used to press the second front wheel shaft 31 in the second clamping groove 7. The second limiting assembly includes a second slide rail 17, a second slider 18, a second limiting plate 19, and a second limiting post 20. The second slide rail 17 is fixed to the top of the jig plate 1 by screws and is arranged perpendicular to the second outer clamping plate 4. The second slider 18 is slidably mounted on the second slide rail 17.

[0057] The second limiting plate 19 is fixed to the top of the second slider 18, and the lower surface of the second limiting plate 19 is in the same plane as the upper surface of the second outer clamping plate 4. Therefore, after the front wheel axle is placed in the clamping groove, when the operator pushes the second limiting plate 19 inward, the second limiting plate 19 will move in contact with the upper surfaces of the second outer clamping plate 4 and the inner clamping plate 2, thereby pressing the second front wheel axle rod 31 in the second clamping groove 7, preventing the front wheel axle from shaking in the clamping groove and affecting the detection results.

[0058] The second limiting column 20 is fixed on the top of the jig plate 1 and is located on the side of the second slide rail 17 away from the second outer clamping plate 4. The second limiting column 20 resists and limits the outward movement of the second limiting plate 19 to prevent the second limiting plate 19 from sliding outward and then slipping off the second slide rail 17.

[0059] The detection component is fixed on the top of the jig plate 1 and is used to detect the inclination angle of the fourth front wheel shaft 33 of the front wheel axle. The detection component includes a positioning groove 21, a positioning block 22, a support 23, a support surface 24, a third slide rail 25, a third slider 26, a third limit plate 27, a limit groove 28 and a third limit column 29. The positioning groove 21 is opened at the top of the jig plate 1. The length of the positioning block 22 is equal to the length of the positioning groove 21, the width of the positioning block 22 is equal to the width of the positioning groove 21, and the positioning block 22 is fixed in the positioning groove 21 by screw fastening. During actual testing, the positioning block 22 can be removed to replace the support 23 with different inclination angles to meet the detection of the fourth front wheel shaft 33 with different inclination angles and improve versatility.

[0060] The support platform 23 is integrally connected to the top of the positioning block 22. The support platform surface 24 is tilted on the side of the support platform 23 close to the inner clamping plate 2. The third slide rail 25 is fixed to the top of the support platform surface 24 by screws, and the third slider 26 is slidably mounted on the third slide rail 25. The third limit plate 27 is fixed to the top of the third slider 26. Because the support platform surface 24 is tilted, the third slide rail 25 and the third limit plate 27 are both tilted, and the third limit plate 27 slides in the tilted direction.

[0061] A limiting slot 28 is defined on the side of the third limiting plate 27 near the third outer clamping plate 5. The diameter of the limiting slot 28 is equal to the diameter of the fourth front wheel shaft 33. Once the front axle is placed in the limiting slot, the first front wheel shaft 30 is pressed against the first limiting plate 15, and the second front wheel shaft 31 is pressed against the second limiting plate 19. The operator then slides the third limiting plate 27 inward. If the limiting slot 28 fits smoothly onto and slides along the fourth front wheel shaft 33, the inclination angle of the fourth front wheel shaft 33 meets the requirements. If the limiting slot 28 fails to fit within the fourth front wheel shaft 33, the front axle is considered defective.

[0062] The third limiting column 29 is fixed on the top of the supporting platform 24 and is located on one side of the third slide rail 25. The third limiting column 29 blocks and limits the outward movement of the third limiting plate 27 to prevent the third limiting plate 27 from sliding outward and then slipping off the third slide rail 25.

[0063] The detection principle of the automatic detection tool for the front wheel axle spring of the utility model for sweeping machines is as follows:

[0064] First, place the front wheel axle in the clamping groove (specifically, the first front wheel axle rod 30 of the front wheel axle is clamped in the first clamping groove 6, the second front wheel axle rod 31 of the front wheel axle is clamped in the second clamping groove 7, and the third front wheel axle rod 32 of the front wheel axle is clamped in the third clamping groove 8). The first limiting plate 15 moves inward to press the first front wheel axle rod 30 of the front wheel axle, and the second limiting plate 19 moves inward to press the second front wheel axle rod 31 of the front wheel axle to prevent the front wheel axle from shaking in the clamping groove and affecting the test results.

[0065] At this time, the operator slides the third limit plate 27 inward. If the limit groove 28 can be smoothly inserted into the fourth front wheel axle 33 and can slide along the fourth front wheel axle 33, it means that the inclination angle of the fourth front wheel axle 33 meets the requirements. If the limit groove 28 cannot be inserted into the fourth front wheel axle 33, it means that the front wheel axle is unqualified.

[0066] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
