[0021] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0022] like Figures 1 to 3 As shown, the washing machine brake disc aperture measurement auxiliary device includes a base plate 1, a lifting frame 4 is provided above the base plate 1, a cylinder 6 is provided in the middle of the base plate 1, and the cylinder 6 is connected to the middle of the bottom end of the lifting frame 4; a chuck 8 is provided at the upper end of the lifting frame 4, a through hole 9 is provided in the middle of the chuck 8, and a pneumatic measuring instrument 7 is provided below the through hole 9.

[0023] The cylinder 6 is connected to the lifting frame 4 through a piston rod to realize the up and down movement of the lifting frame 4. The pneumatic measuring instrument 7 is a static structure. When the manipulator places the brake disc on the chuck 8, the chuck 8 is used to clamp and limit the brake disc. The through hole 9 runs through the top of the lifting frame 4 and the chuck 8. The through hole 9 allows one end of the brake disc with a mounting hole to extend from the chuck 8. When measuring, the lifting frame 4 descends until the pneumatic measuring instrument 7 enters the mounting hole. There is a gap between the pneumatic measuring instrument 7 and the inner wall of the mounting hole. The pneumatic measuring instrument 7 can convert the change of the inner diameter size into the change of the compressed air flow or pressure according to the proportional relationship between the gas flow rate, pressure and gap, thereby indicating the numerical value; compared with the use of the inner diameter micrometer, the use of the pneumatic measuring instrument 7 has the advantages of simpler operation and higher measurement accuracy, and can also be applied to large-scale measurement.

[0024] like Figure 1 As shown, a mounting frame 3 is also provided on the bottom plate 1, and both ends of the mounting frame 3 are fixedly connected to both sides of the bottom plate 1. The mounting frame 3 is in a U-shaped structure, and the pneumatic measuring instrument 7 is arranged in the middle of the upper end of the mounting frame 3. The mounting frame 3 is mounted with the pneumatic measuring instrument 7 installed just below the through hole 9, and the pneumatic measuring instrument 7 is ensured to be horizontal, which is conducive to improving the stability of the measurement process.

[0025] like Figure 1 As shown, mounting plates 2 are provided at both ends of the bottom plate 1, guide rails 5 are provided on the mounting plates 2, and the side of the lifting frame 4 cooperates with the guide rails 5. The guide rails 5 are used to limit and guide the lifting process of the lifting frame 4 to ensure that the movement path of the lifting frame 4 is a straight line. The guide rails 5 are groove structures, and the lifting frame 4 can be accurately guided by moving along the guide rails 5.

[0026] like Figure 1 As shown, a stopper 10 is provided at the end of the chuck 8, and the stopper 10 is an arc-shaped structure, and the stopper 10 is arranged at equal intervals along the circumferential direction. The chuck 8 and the stopper 10 are an integrated structure, and a plurality of stoppers 10 arranged at equal intervals are used to limit the brake disc to prevent instability after the manipulator releases the brake disc, and the space between the stoppers 10 is used as a placement space for the manipulator clamp structure, which can facilitate the manipulator to grab the brake disc; the chuck 8 is a circular structure, and the stopper 10 with an arc-shaped structure is adapted to the shape of the brake disc, which expands the contact area between the stopper 10 and the brake disc, and is conducive to improving the stability of the brake disc placed on the chuck 8.

[0027] like Figure 2As shown, a blow port 15 is provided on one side of the bottom plate 1. Before measuring the aperture, the manipulator can grab the brake disc, align its mounting hole and cover the blow port 15, and the blow port 15 blows air outward to remove iron filings adhered to the brake disc and the inside of the mounting hole after processing, so as to prevent the iron filings from affecting the measurement accuracy of the pneumatic measuring instrument 7.

[0028] like Figure 1 As shown, the lifting frame 4 is a square-shaped structure. The lifting frame 4 and the installation frame 3 are both frame-type structures. The lifting frame 4 is designed as a square-shaped structure, so that the upper end of the installation frame 3 after installation can be located inside the lifting frame 4, which is conducive to reducing the space occupied by the device and making the overall structure of the device more compact. It can be conveniently set at the loading or unloading stage of the manipulator on the machine tool without affecting the use of the existing machine tool structure; and it can reduce the weight of the lifting frame 4, reduce the resistance of the cylinder 6 to push, and also save material costs.

[0029] like Figures 1 to 3 As shown, the cylinder 6, the pneumatic measuring instrument 7 and the through hole 9 are all in the same straight line. The above structure can ensure that the lifting frame 4 is more evenly pushed by the cylinder 6, and can facilitate the installation hole of the brake disc to accurately extend from the through hole 9, while allowing the pneumatic measuring instrument 7 to accurately enter the installation hole to measure the aperture.

[0030] like Figure 1 As shown, first reinforcing ribs 11 are provided on both sides of the mounting frame 3, and second reinforcing ribs 12 are provided on the side of the mounting plate 2. The first reinforcing rib 11 is located in the middle of the long side of the bottom plate 1, and the second reinforcing rib 12 is located in the middle of the short side of the bottom plate 1. The provision of reinforcing ribs is conducive to setting the mounting frame 3 and the mounting plate 2 perpendicular to the bottom plate 1, while improving the structural strength of the mounting frame 3 and the mounting plate 2.

[0031] like Figure 1 and Figure 3 As shown, the bottom plate 1 is provided with first waist-shaped holes 13 on both sides of the cylinder 6, and the bottom plate 1 is provided with second waist-shaped holes 14 on both sides of the mounting plate 2, and the first waist-shaped holes 13 and the second waist-shaped holes 14 are arranged in pairs. The first waist-shaped holes 13 are arranged parallel to the long side of the bottom plate 1, and the second waist-shaped holes 14 are arranged parallel to the short side of the bottom plate 1. The above structure is conducive to the uniform distribution of the connecting parts, so that the whole device can be stably installed on the horizontal surface, so that the lifting process of the lifting frame 4 is always perpendicular to the horizontal plane.

[0032] like Figure 2As shown, the measurement steps of using the device are as follows: after the brake disc is processed, the manipulator grabs the brake disc and moves it along the crossbeam. When it moves above the air outlet 15, the manipulator controls the brake disc to descend so that the mounting hole covers the air outlet 15. The air outlet 15 blows air to remove iron filings. Then the manipulator moves the brake disc to the chuck 8. At this time, the mounting hole extends from the through hole 9 and is located directly above the pneumatic measuring instrument 7. The cylinder 6 starts to move the lifting frame 4 downward. When the mounting hole covers the pneumatic measuring instrument 7, the pneumatic measuring instrument 7 starts to measure the inner diameter of the mounting hole, thereby completing the aperture measurement of the brake disc. Then the cylinder 6 starts to move the lifting frame 4 upward and reset it, and the subsequent measurement process can be carried out.

[0033] The washing machine brake disc aperture measurement auxiliary device controls the lifting of the lifting frame 4 through the cylinder 6 and combines the use of the pneumatic measuring instrument 7. A chuck 8 and a guide rail 5 are also provided to improve the stability of the measuring process. It not only stabilizes the posture of the brake disc during measurement, but also simplifies the measuring process and improves the measuring accuracy, solving the problems of high labor intensity and poor measuring accuracy in existing manual measurement. The device has a compact overall structure, high stability, and small space occupation, and can be directly installed in the loading stage of an existing machine tool.

[0034] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
