Distribution diameter automatic pitch-control five-axle wheel screwing equipment

Abstract

The invention discloses a distribution diameter automatic pitch-control five-axle wheel screwing equipment which comprises a screwing bracket, a hoisting mechanism and five screwing shafts, wherein a screwing shaft fixing plate is fixed at one end of the screwing bracket; five through holes positioned in the same circumference are distributed on the screwing shaft fixing plate; the screwing shafts are fixed on the screwing shaft fixing plate; the hoisting mechanism is fixed at the other end of the screwing bracket; multiple radial pitch-control adjusting mechanisms are arranged on the screwing shaft fixing plate; the radial pitch-control adjusting mechanisms are connected with the screwing shafts in a one-to-one correspondence manner and used for adjusting the radius of the circumference in which each screwing shaft is positioned; each radial pitch-control adjusting mechanism comprises a reducing air cylinder and a sliding block, the cylinder body end of the reducing air cylinder is fixedly connected with the screwing shaft fixing plate through a fixing bracket, and the piston rod end of the reducing air cylinder is connected with the sliding block through a connecting bracket; and the sliding blocks are fixedly connected with the screwing shafts, and each through hole is an elongated sliding chute hole extending along the radial direction of the circumference. The distribution diameter automatic pitch-control five-axle wheel screwing equipment has the advantages of high automation degree, simpleness and convenience in operation, and high efficiency, and is applicable to large-scale flow line production on an automotive assembly line.

Description

technical field [0001] The invention relates to the field of automatic fastening of bolts in the automobile manufacturing industry, in particular to a five-axis wheel nut tightening device with automatic variable distance distribution circle diameter. Background technique [0002] On the heavy-duty truck assembly line, the connection between the wheel and the axle is fixed on the axle by tightening 10 nuts. Nowadays, five-axis tightening equipment is generally used to tighten 10 nuts twice. The traditional tightening method uses a hand-held pneumatic wrench to tighten each nut one by one. The pneumatic wrench has low tightening torque accuracy, high noise, high labor intensity and low efficiency, and cannot guarantee the balance of torque on each nut. The existing five-axis nut tightening equipment cannot meet the requirements of multi-variety collinearity because the position of the tightening axis is not adjustable, or the manual adjustment of the position of the tightenin...

The traditional tightening method uses a hand-held pneumatic wrench to tighten each nut one by one. The pneumatic wrench has low tightening torque accuracy, high noise, high labor intensity and low efficiency, and cannot guarantee the balance of torque on each nut.

The existing five-axis nut tightening equipment or the non-adjustable position of the tightening axis cannot meet the requirements of multi-variety collinearity, or the manual adjustment of the position of the tightening axis cannot meet the production cycle requirements
