Problems solved by technology

Therefore, for structures such as the inner and outer cylinder components, the inner cylinder can still rotate after being integrally fixed, the existing press-fitting equipment lacks effective positioning and cannot meet the assembly requirements
[0004] In addition, there are also some automatic press-fitting equipment that can realize the positioning of three parts by adding sensors and mechanical arms, but such solutions have disadvantages such as high cost, complex structure, and difficult maintenance, and are not suitable for small batch production

Embodiment 1

[0040] like Figure 2-Figure 6 As shown, this embodiment provides a washing machine tub hoop press-fitting device, which is used to press-fit the tub hoop 300 onto the inner tub 200 of the washing machine tub assembly. The hoop press-fitting equipment includes a frame, a positioning device and a press-fitting device. Frame is used for supporting whole body, and it comprises the workbench 11 that is arranged in horizontal direction and the support frame 12 that is provided with in vertical direction, and support frame 12 of present embodiment is located at the side of workbench 11, and with workbench 11 Fixed connection. The positioning device includes an outer cylinder positioning device 21, an inner cylinder positioning device 22 and a cylinder hoop positioning device 23, wherein the outer cylinder positioning device 21 is installed on the workbench 11 to limit the horizontal position and axial rotation of the outer cylinder 100 , the inner cylinder positioning device 22 is...

Embodiment 2

[0053] This embodiment provides another washing machine drum hoop pressing device, including a frame, a positioning device, a pressing device and a guiding device 41, wherein the structure of the frame, positioning device, and guiding device 41 is the same as that in Embodiment 1, here No more details, the difference between this embodiment and Embodiment 1 is that the press-fitting device of this embodiment adopts an automatic press-fitting method.

[0054] The press-fitting device of this embodiment includes a driving mechanism, the driving mechanism is fixed on the top of the support frame 12, and the output end of the driving mechanism is connected with the top plate 231 of the cylinder hoop positioning device 23, and the cylinder hoop positioning device 23 is driven to move up and down by the driving mechanism, thereby The barrel collar 300 is press fitted onto the inner barrel 200 of the barrel assembly. Specifically, the driving device may be a mechanism such as an air ...

Abstract

The invention relates to the technical field of washing machine manufacturing, and discloses press-fitting equipment of a washing machine barrel hoop. The press-fitting equipment is used for press-fitting a cylinder hoop on an inner cylinder of a cylinder assembly and comprises a rack, a positioning device and a press-fitting device, wherein the rack comprises a workbench and a supporting frame, the positioning device comprises an outer cylinder positioning device arranged on the workbench, an inner cylinder positioning device arranged on the supporting frame and a cylinder hoop positioning device, and the press fitting device is connected with the cylinder hoop positioning device and can drive the cylinder hoop positioning device to move in the axis direction of the cylinder assembly. According to the press-fitting equipment, accurate positioning of the cylinder hoop and the inner and outer cylinders after press fitting is achieved through the positioning device, stable and reliable movement of the cylinder hoop is achieved through the press fitting device, the press fitting precision of the cylinder hoop is guaranteed, the problems of positioning and the press fitting in the assembling process of the inner cylinder and the cylinder hoop of a washing machine are solved, the positioning device has the advantages of being simple in structure, convenient to operate, low in cost,high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of washing machine manufacturing, in particular to a washing machine cylinder hoop press-fitting device. Background technique [0002] In the existing drum washing machine, during the high-speed rotation of the inner drum, there is a potential safety hazard that the inner drum may explode and injure people. At present, there is a solution to install a hoop on the inner cylinder as a safety device, such as figure 1 As shown, the cylinder band 300 is fixed on the inner cylinder 200 by the friction force generated by the tight fit, so a press-fitting device is required to press-fit the cylinder band to the designated position of the inner cylinder 200 . [0003] Since the concept of the hoop in the drum washing machine has just been proposed, there is currently no press-fitting equipment for the hoop assembly, and the existing press-fitting equipment patents (such as: CN108274216A, CN207309850U, CN108747964A a...
