Abstract

A flexible fixture base capable of achieving the quick changing of a fixture is used in the field of welding for mechanical manufacturing. A cylinder body of a jacking air cylinder of a floating mechanism is fixed on a fixture base; at the time of working, the jacking air cylinder below the floating mechanism pushes the floating mechanism up to an upper limit; at the time of welding, the jacking air cylinder releases air, and a fixture body presses down compression springs by gravity to contact a lower electrode of a welding gun; after the fixture body is stabilized, welding is started; a turnover mechanism is connected with the floating mechanism through bearing seats and floats up or down along with the floating mechanism; turnover air cylinders of the turnover mechanism are connected with turnover shafts on the left sides of the turnover air cylinders; the turnover air cylinders act to drive fixture mounting plates on the turnover shafts to turn over; a quick positioning device performs quick positioning through two V-shaped blocks; and positioning holes in two sides perform precise positioning through positioning pins. The flexible fixture base can achieve the up and down floating, turnover angles and quick positioning of the fixture body as well as the automatic compensation of the abrasion loss of an electrode through the floating mechanism, the turnover mechanism and thequick positioning device; moreover, the flexible fixture base can cooperate with a three-axis straight-line automatic welding machine to achieve flexible welding; and therefore, the production inputcost is reduced and the universality of the device is enhanced.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing and welding, in particular to a flexible quick-change fixture base used in the manufacture of auto parts. Background technique [0002] At present, in the machinery manufacturing industry such as auto parts, the base of the combined welding jig only serves as a fixed jig. For automatic welding of solder joints, a six-axis spot welding robot must be invested, and the production cost is high. Contents of the invention [0003] In order to overcome the lack of flexibility of the existing clamp base, the purpose of the invention is to provide a flexible quick-change clamp base, which can realize the up and down floating, flipping and quick positioning of the clamp base. [0004] In order to achieve the purpose of the above invention, the present invention includes a floating mechanism, an overturning mechanism, and a quick positioning device; the cylinder body of the jacking cylind...
