DETAILED DESCRIPTION

[0036] The utility model will be further described below in combination with the embodiments shown in the drawings.

[0037] As Figures 2-4 shown, it is the structure schematic diagram of front axle spring test fixture for sweeping robot of the utility model, it is usually used for detecting Figure 1 the front axle shown in the drawing, for detecting whether the first front axle shaft 23 and the third front axle shaft 25 of the front axle are parallel and whether the inclination angle of the second front axle shaft 24 meets the requirement.

[0038] As Figure 1 shown, the front axle is integrally made through spring making machine, so the front axle can also be called front axle spring, and it includes the first front axle shaft 23, the second front axle shaft 24, the third front axle shaft 25, the fourth front axle shaft 26, the first transition part 27, the second transition part 28, the third transition part 29, the first clamping part 30 and the second clamping part 31.

[0039] The second front axle shaft 24 is integrally connected at one end of the first front axle shaft 23, and the second front axle shaft 24 is perpendicular to the first front axle shaft 23; the third front axle shaft 25 is integrally connected at one end of the second front axle shaft 24 away from the first front axle shaft 23, and the third front axle shaft 25 is perpendicular to the second front axle shaft 24. The first front axle shaft 23, the second front axle shaft 24 and the third front axle shaft 25 are located in the same plane.

[0040] The first transition part 27 is transitionally connected with the first front axle shaft 23 and the second front axle shaft 24, the second transition part 28 is transitionally connected with the second front axle shaft 24 and the third front axle shaft 25, and the first transition part 27 and the second transition part 28 are arranged to avoid sharp corners at the connection, avoid scratching the worker during installation, and avoid stress concentration and cause the front axle to break during use.

[0041] The fourth front wheel axle 26 is obliquely connected to the end of the third front wheel axle 25 away from the second front wheel axle 24, and the fourth front wheel axle 26 and the third front wheel axle 25 are connected by a third transition portion 29, and the third transition portion 29 and the second transition portion 28 have the same function.

[0042] The first clamping portion 30 is integrally provided at one end of the first front wheel shaft 23 near the second front wheel shaft 24, and the second clamping portion 31 is integrally provided at one end of the fourth front wheel shaft 26 near the third front wheel shaft 25. The first clamping portion 30 and the second clamping portion 31 are formed by stamping on the first front wheel shaft 23 and the fourth front wheel shaft 26. The first clamping portion 30 and the second clamping portion 31 are used to stop and limit the bearings inserted into the first front wheel shaft 23 and the fourth front wheel shaft 26.

[0043] The jig plate 1 is a rectangular metal plate that primarily serves as a support. The second fixing plate 10 is screwed to the top of the jig plate 1. A push slot 11 is defined on one side of the second fixing plate 10. During actual testing, the fourth front wheel axle rod 26 of the front axle is engaged in the push slot 11. The front axle is then pushed forward along the push slot 11 until the first front wheel axle rod 23 is pushed into the testing slot 18 for testing.

[0044] The width of the push groove 11 is equal to the diameter of the fourth front wheel axle 26. The setting of the push groove 11 can limit the fourth front wheel axle 26 and prevent the front wheel axle from swinging and affecting the accuracy of the detection result when the front wheel axle is pushed forward.

[0045] The clamping plate 2 is screwed to the top of the jig plate 1. A slot 3 is defined at the bottom of the clamping plate 2, near the second fixing plate 10. When the front axle is pushed forward, the third front wheel shaft rod 25 pushes into the slot 3, preventing interference. The height of the slot 3 is equal to the diameter of the third front wheel shaft rod 25, so it also serves to limit the vertical position of the front axle when it is pushed forward.

[0046] The first fixing plate 4 is fixed to the top of the fixture plate 1 by screw fastening, and the baffle 5 is integrally connected to the side of the first fixing plate 4 close to the clamping plate 2. The guide plate 6 is fixed to the side of the baffle 5 close to the clamping plate 2, and the top of the guide plate 6 is provided with an inclined guide slope.

[0047] like Figure 2 As shown, during testing, the fourth front wheel axle 26 is stuck in the push groove 11. At this time, the third front wheel axle 25 and the fourth front wheel axle 26 are in the same plane, while the second front wheel axle 24 is in an inclined state. The guide slope cooperates with the inclined second front wheel axle 24, so the front wheel axle is pushed forward until the second front wheel axle 24 abuts the guide slope, and the first front wheel axle 23 then extends into the testing groove 18.

[0048] As Figure 5 shown, the limiting plate 7 is fixed on the top of the guide slope, and a limiting slot is formed between the limiting plate 7 and the baffle 5, the width of the limiting slot is equal to the diameter of the second front axle shaft 24, so when the front axle is pushed forward and the second front axle shaft 24 is against the guide slope, the second front axle shaft 24 is clamped in the limiting slot, and the first front axle shaft 23 extends into the detection slot 18.

[0049] The first and second avoiding parts 8 and 9 are respectively arranged on the side of the limiting plate 7 close to the baffle 5, and the first avoiding part 8 is used to avoid the first transition part 27, and the second avoiding part 9 is used to avoid the second transition part 28 when the front axle is pushed forward.

[0050] As Figure 6 shown, the support plate 12 is fixed on the top of the jig plate 1, and the extension plate 13 is integrally connected on the side of the support plate 12 close to the clamping plate 2, and the support plate 12 and the extension plate 13 are both made of insulating material, such as bakelite or ceramic. When detecting the front axle, the closed circuit is avoided between the upper and lower conductive sheets 14 and 15 through the support plate 12 and the extension plate 13.

[0051] The upper conductive sheet 14 is fixed on the top of the extension plate 13, and the lower conductive sheet 15 is fixed on the bottom of the extension plate 13, and since the upper and lower conductive sheets 14 and 15 are separated by the insulating extension plate 13, the upper and lower conductive sheets 14 and 15 are open circuit and do not form a closed circuit.

[0052] The upper pressing plate 16 is fixed on the top of the upper conductive sheet 14, and the lower pressing plate 17 is fixed on the bottom of the lower conductive sheet 15, and the upper pressing plate 16 presses the upper conductive sheet 14, and the lower pressing plate 17 presses the lower conductive sheet 15, so as to avoid the upper and lower conductive sheets 14 and 15 from falling off from both sides of the extension plate 13. In actual fixing, the fastening bolt is passed through the upper pressing plate 16 and the upper conductive sheet 14 and fixed in the extension plate 13, and the fastening bolt is passed through the lower pressing plate 17 and the lower conductive sheet 15 and fixed in the extension plate 13, so as to complete the fixing of the upper and lower conductive sheets 14 and 15.

[0053] The threaded hole is formed on the upper pressing plate 16, the upper adjusting bolt 19 is screwed through the threaded hole and abuts against the top of the upper conductive sheet 14, and by screwing the upper adjusting bolt 19 downward, the upper conductive sheet 14 is deformed downward. The upper locking nut 21 is screwed on the upper adjusting bolt 19, so as to abut against the top of the upper pressing plate 16, and the position of the upper adjusting bolt 19 after adjustment is ensured not to change.

[0054] The lower pressing plate 17 is provided with a threaded hole, and the lower adjusting bolt 20 is screwed through the threaded hole and abuts against the bottom of the lower conducting sheet 15. By screwing the lower adjusting bolt 20 upward, the lower conducting sheet 15 is deformed upward. The lower locking nut 22 is screwed on the lower adjusting bolt 20 and abuts against the bottom of the lower pressing plate 17, so that the position of the lower adjusting bolt 20 after adjustment is ensured not to change.

[0055] As shown in Figure 6 By screwing the upper adjusting bolt 19 and the lower adjusting bolt 20, the distance between the upper conducting sheet 14 and the lower conducting sheet 15, i.e. the width of the detection groove 18, is changed, so that the versatility of the jig is improved, and the width of the detection groove 18 can be adjusted according to actual needs to meet the detection of first front axle shaft rods 23 of different diameters.

[0056] When the front axle shaft is pushed forward, the third front axle shaft rod 25 is pushed into the clamping groove 3, the second front axle shaft rod 24 abuts against the guide inclined surface, at this time, the second front axle shaft rod 24 is clamped in the limiting groove, and the first front axle shaft rod 23 extends into the detection groove 18. If the first front axle shaft rod 23 and the third front axle shaft rod 25 are parallel, the first front axle shaft rod 23 does not contact the upper conducting sheet 14 and the lower conducting sheet 15, at this time, the upper conducting sheet 14 and the lower conducting sheet 15 are in open circuit; if the first front axle shaft rod 23 and the third front axle shaft rod 25 are not parallel, i.e. the first front axle shaft rod 23 is inclined to be arranged, at this time, the upper conducting sheet 14 and the lower conducting sheet 15 are communicated through the inclined first front axle shaft rod 23, so that a passage is formed.

[0057] The power supply is fixed on the top of the jig plate 1, and a commercially available dry battery is selected as the power supply. The first wire is connected with the upper conducting sheet 14, the second wire is connected with the lower conducting sheet 15, and a small bulb is connected on the second wire. As shown in Figure 7 The detection groove 18 between the upper conducting sheet 14 and the lower conducting sheet 15 constitutes a switch of the circuit.

[0058] If the first front axle shaft rod 23 and the third front axle shaft rod 25 are parallel, the first front axle shaft rod 23 does not contact the upper conducting sheet 14 and the lower conducting sheet 15, at this time, the upper conducting sheet 14 and the lower conducting sheet 15 are in open circuit, and the small bulb does not emit light; if the first front axle shaft rod 23 and the third front axle shaft rod 25 are not parallel, i.e. the first front axle shaft rod 23 is inclined to be arranged, at this time, the upper conducting sheet 14 and the lower conducting sheet 15 are communicated through the inclined first front axle shaft rod 23, so that a passage is formed, and at this time, the small bulb emits light.

[0059] The utility model discloses a front wheel axle spring test fixture for floor cleaning robot, through setting up upper conducting sheet 14 and lower conducting sheet 15, constitute a closed circuit, the detection groove 18 between upper conducting sheet 14 and lower conducting sheet 15 is equivalent to the switch of this circuit, then push the front wheel axle to the first front wheel axle stem 23 and extend into the detection groove 18, if the first front wheel axle stem 23 and the third front wheel axle stem 25 are parallel, the first front wheel axle stem 23 does not contact with upper conducting sheet 14 and lower conducting sheet 15, at this moment, upper conducting sheet 14 and lower conducting sheet 15 are in open circuit, and the small bulb does not emit light, if the first front wheel axle stem 23 and the third front wheel axle stem 25 are not parallel, namely, the first front wheel axle stem 23 is inclined to set, at this moment, upper conducting sheet 14 and lower conducting sheet 15 will be connected through the inclined first front wheel axle stem 23, to form the passage, at this moment, the small bulb emits light.
