Problems solved by technology

Its disadvantages are: firstly, after the wheel hub is removed from the fixture and rotated at a certain angle and then repositioned, there is a positioning error in the wheel hub itself; secondly, when welding different small parts to be welded to the wheel hub, each small part to be welded The relative positions of the parts and the hub are not exactly the same, and the small parts of the hub have positioning errors; both the hub and the small parts to be welded have secondary positioning errors, which affect the welding accuracy of the small parts to be welded

Abstract

The invention discloses an automatic welding system of hub small parts in the field of automatic welding equipment. The system comprises a base provided with a welding robot; a welding revolving mechanism is arranged on the base, and is connected with a flowing centered clamping mechanism; a hub loading / unloading guide rail is arranged below a hub; a small part loading mechanism is arranged on the base, and includes a horizontal slide base and a vertical slide base; the horizontal slide base is slidingly connected with the base; the vertical slide base is slidingly connected with the horizontal slide base; a support table is arranged on the vertical slide base; a lower support plate is mounted on the support table; a center shaft pipe is arranged on the lower support plate, and is coated with small parts to be welded; a stopper is arranged at one end of the center shaft pipe, and the other end of the center shaft pipe is connected with a swing rod; an upper gland is embedded above the lower support plate; positioning pin shafts are arranged on two sides of the upper gland; a positioning groove is formed in the lower support plate; and two sides of the lower support plate are connected with locking glands. The system can automatically weld the small parts to be welded on the hub, eliminates secondary positioning errors, and improves the welding precision and efficiency.

Description

Technical field [0001] The invention belongs to the field of automatic welding equipment, and particularly relates to a small-part welding system for a wheel hub. Background technique [0002] The wheel hub is a barrel-shaped metal part with the inner profile of the tire supporting the tire and the center sleeved on the shaft. The wheels on the market can be divided into two categories: steel wheels and alloy wheels according to their materials. Both have advantages and disadvantages. During the manufacturing process of the wheel hub, a number of small parts need to be welded and fixed on the inner ring. At present, the small parts to be welded are usually welded and fixed on the wheel hub to be welded manually. In order to improve the welding quality and efficiency of wheel hubs, and meet the demand for mass production, technicians use welding robots instead of manual welding, reducing welding costs. In the prior art, the welding process for welding small parts to be welded on...
