Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conical thin-walled size measurement, and particularly relates to a drum washing machine decorative ring measuring jig and method. BACKGROUND

[0002] The drum washing machine is one of household appliances which can be opened from the front side; as a large household appliance, the washing machine needs to occupy a large space after installation, and the front opening design can set a horizontal plate above the drum washing machine to increase the utilization rate of the space above the drum washing machine, and has better space utilization compared with the pulsator washing machine. Due to the front opening design of the drum washing machine, the washing machine door and the washing machine body need to have better sealing and waterproof effect compared with the pulsator washing machine.

[0003] The existing drum washing machine usually comprises a washing machine body, a drum and a door body, the front side of the washing machine body is provided with a clothes throwing opening, the drum is rotatably arranged in the washing machine door body, the drum is used for containing clothes to be washed and driving the clothes to be washed to rotate in the drum for cleaning, and the door body is arranged on the front side of the washing machine body and blocks the clothes from rolling out of the drum. Since the door body and the washing machine body need to ensure the sealing effect after being closed during the cleaning process of the clothes, the door body is usually designed in a conical shape, and the size of the door body gradually decreases from outside to inside. The conical structure can better ensure that the door body and the washing machine body have a better sealing effect after being closed.

[0004] In the prior art, a conical decorative ring is usually arranged between the washing machine body and the door body. The outer side wall of the decorative ring is provided with a part for fixing the decorative ring to the washing machine body, and the side wall of the decorative ring is also provided with a through hole for the hinge connection of the door body and the washing machine body. The through hole is usually located at the larger end of the decorative ring, and the inner wall of the decorative ring is relatively smooth, so that the door body abuts against the inner wall of the decorative ring, and the inner side of the door body presses against the inner wall of the decorative ring and extends into the washing machine body, and the smaller end has a good adhesion with the door body, which has a good auxiliary effect on improving the sealing and waterproof effect of the door body. In order to meet the basic requirements, it is necessary to ensure that the size of the designed decorative ring matches the size required by the clothes throwing opening on the front side of the washing machine body, so as to improve the assembly efficiency and the sealing and waterproof effect of the drum washing machine. Therefore, it is necessary to measure the size of the decorative ring, especially the inner diameter of the smaller end of the decorative ring, which is an important size during the installation of the decorative ring.

[0005] Since the decorative ring is a conical thin-walled structure, and the decorative ring cannot well maintain its circumferential state without support and is deformed, it is easy to have a large error in the process of directly measuring the size of the decorative ring due to the deformation, which leads to a large error in the size measurement of the decorative ring, and further affects the subsequent installation efficiency of the decorative ring.

[0055] S4, positioning the measuring tool by the first positioning structure 41 and the second positioning structure 42 to measure multiple size data of the decorative ring 3;

[0056] S5, calculating the average value of the multiple data to obtain the size of the decorative ring 3.

[0057] Before placing the decorative ring 3, ensure that the locking part 2 is in the unlocked state, so as to avoid the friction between the decorative ring 3 and the free end 211 of the cantilever beam 21 or the pressing rod 22 during the installation process of the decorative ring 3, and ensure that the decorative ring 3 is not damaged before and after measurement; rotate the decorative ring 3 so that the connecting part 31 is aligned with the pressing rod 22, ensure the stability of the decorative ring 3 during measurement, and avoid the influence of the different heights of the decorative ring 3 in the circumferential direction on the accuracy of measurement during measurement; the first positioning structure 41 and the second positioning structure 42 are provided in the form of grooves 411 or protruding ribs 412, and two measurement reference points of a measuring tool (such as a vernier caliper) are positioned, so as to ensure that the measurement is the size in the diameter direction of the measurement workbench 1, improve the accuracy of measurement, and reduce the measurement error; during measurement, a plurality of data are obtained through a plurality of groups of two-axially symmetric grooves 411 or protruding ribs 412, and the average value is obtained through a plurality of data to obtain the inner diameter size of the smaller end of the decorative ring 3, and the measurement error is further reduced. The measurement workbench 1 supports the decorative ring 3, and deformation of the thin-walled decorative ring 3 during measurement is avoided, and the accuracy of measurement is affected.

[0058] In addition to the preferred embodiments described above, the present application also has other embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.
