Description

Technical Field

[0001] This utility model relates to the technical field of dishwasher assembly equipment, specifically to a dishwasher inner tank riveting and positioning fixture. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for home use and mainly include cabinet-style, countertop-style, sink-integrated, and combined models. With the increasing living standards of people, the task of washing dishes can be handled by a dishwasher, saving time.

[0003] Existing dishwashers generally include a dishwasher inner tub, a flange disposed on the inner tub and used to seal between the inner tub and the outer shell of the drawer-type dishwasher. The flange is mostly made of plastic or rubber, and the inner tub itself needs to have a connection structure that mates with the flange, which makes the inner tub structure more complicated and increases the difficulty of processing.

[0004] Patent application number 201810414162.8 discloses an inner liner assembly and a dishwasher. The inner liner assembly includes an inner liner with a receiving cavity having a top opening; a sealing frame disposed on the top of the inner liner, with a sealing groove on the side of the sealing frame facing the inner liner, the edge of the opening being received within the sealing groove. The inner liner assembly includes a limiting flange disposed on the outer side wall of the top of the inner liner; a supporting rib is provided on the side wall of the sealing groove corresponding to the limiting flange, the bottom surface of the limiting flange abutting against the top of the supporting rib.

[0005] Although the sealing effect of the sealing frame and the inner liner is improved, the inner liner body needs to be bent at multiple angles to form the limiting folded edge and the inner liner as an integral structure. The inner liner molding is complicated and increases the processing difficulty. It is inefficient for producing inner liners of different heights and sizes. It also leads to the complexity of the inner liner mold structure. Multiple molds of different specifications are required for inner liners of different sizes, which not only increases the cost but also has poor versatility. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a dishwasher inner liner riveting and positioning fixture. This fixture is characterized by its compact structure, time and labor savings, and good operational stability. It solves the problem of fixture limitation during the dishwasher inner liner riveting process. It serves as a positioning and limiting device during the dishwasher inner liner riveting process, improving the quality stability and processing accuracy of the riveting process.

[0007] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

A push plate is located at the front end of the core-pulling fixing plate. Pressure plates are located on both sides of the upper end of the push plate. A cylinder fixing base plate is located at the lower end of the core-pulling fixing plate. A telescopic cylinder, which drives the pressure plates to adjust their tension, is located between the cylinder fixing base plate and the push plate.

[0009] Preferably, the upper rear end of the core-pulling fixing plate is provided with several positioning cylinders that are respectively connected to the push plate and the pressing plate, and several guide rods that are movably nested with the gearbox are provided below the positioning cylinders.

[0010] Preferably, bearing seats are provided between the positioning cylinder and the push plate, between the positioning cylinder and the pressing plate, and between the guide rod and the gearbox.

[0011] Preferably, the gearbox is equipped with a gear pair that drives the positioning fixtures on both sides to open and retract synchronously, and the lower end of the fixture base plate is equipped with a gear motor that meshes with the gear pair in a helical gear manner.

[0012] Preferably, a connecting joint is provided between the telescopic cylinder and the push plate.

[0013] Preferably, a transition push block is provided between the clamping plate and the push plate, and is fixed to the clamping plate with screws.

[0014] This invention can achieve the following effects:

[0015] This invention provides a positioning fixture for riveting dishwasher inner liner, which, compared with existing technologies, features a compact structure, saves time and labor, and offers good operational stability. It solves the problem of fixture limitation during the riveting process of the dishwasher inner liner. It plays a positioning and limiting role during the riveting process of the dishwasher inner liner, improving the quality stability and processing accuracy of the riveting process.
