New energy automobile wheel hub valve hole perforation fixture with automatic positioning function

Abstract

The invention relates to a new energy automobile wheel hub valve hole perforation fixture with an automatic positioning function. The new energy automobile wheel hub valve hole perforation fixture comprises a support bottom plate, a rotary device, a fixing device, a clamping device and a hole drilling device. The rotary device is mounted on the top of the support bottom plate, the fixing device ismounted on the top of the rotary device, the clamping device is connected with the support bottom plate, and the hole drilling device is mounted on the clamping device. The new energy automobile wheel hub valve hole perforation fixture has the advantages that the difficult problems of incapability of fixing existing wheel hubs for existing wheel hub structures when existing valve holes are drilled in the existing new energy automobile wheel hubs in certain factories, incapability of firmly fixing the existing wheel hubs, deviation when the existing wheel hubs rotate under the control, requirements on manually polishing the existing valve holes and the like at present can be solved by the aid of the new energy automobile wheel hub valve hole perforation fixture; the new energy automobile wheel hub valve hole perforation fixture can have functions of stably fixing new energy automobile wheel hubs and drilling and polishing valve holes in the wheel hubs, the wheel hubs can be fixed for wheel hub structures by the aid of the new energy automobile wheel hub valve hole perforation fixture and can be firmly fixed by the aid of the new energy automobile wheel hub valve hole perforation fixture, the wheel hubs can stably rotate without deviation under the control, the valve holes can be automatically polished, and the like.

Description

technical field [0001] The invention relates to the technical field of new energy sources, in particular to an automatic positioning jig for punching a valve hole in a wheel hub of a new energy vehicle. Background technique [0002] The wheel hub is a metal part that is centrally installed on the transmission shaft and supports the tire. There are many types of wheel hubs on the market. Now new energy vehicles mainly use aluminum alloy wheels. Aluminum alloy wheels have good heat dissipation, light weight, high precision, and more beautiful. Advantages: There are three manufacturing methods of aluminum alloy wheels, namely, gravity casting, forging, and low-pressure precision casting. Among them, the cast wheels account for more than 90%. Hole opening action, because the tires are basically tubeless tires now, tires with inner tubes are rare, and the tubeless tires are in contact with the hub, so the airtightness of the hub is highly required, such as figure 1 As shown, the...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a new energy vehicle wheel hub valve hole punching jig that can be automatically positioned, which can solve the problem that the wheel hub cannot be aimed at the wheel hub when some existing factories drill the valve hole of the new energy vehicle hub. The structure fixes the hub, the positioning of the hub will be deviated, the fixation of the hub is not firm, there will be deviation when controlling the rotation of the hub, and it is difficult to manually polish the valve hole; it can realize stable fixing of the hub of new energy vehicles, and the adjustment of the hub The function of drilling and grinding the valve hole has the advantages of being able to fix the hub according to the structure of the hub, automatically positioning without deviation, fixing the hub firmly, controlling the rotation of the hub smoothly without deviation, and automatically grinding the valve hole, etc.
