The welding operation machine has a guide seat force, guide wheel contact surface, has the advantages of stable and reliable transmission. The equipment is mainly composed of vertical column, horizontal arm, guiding device, lifting mechanism and climbing ladder. The upright column is a rectangular beam, and a rectangular double guide rail structure. The vertical column is made of rectangular pipe, and then is machined after welding. The vertical column and the guide seat are clamped by three sides of each guide rail, which is more stable and reliable than the triangular guide rail. The horizontal arm also adopts the rectangular tube forming, the rectangular double guide rail structure form, after the welding machine processing, can guarantee the processing after the linear degree and the equipment operation stability. The horizontal movement of the horizontal arm is realized by the variable frequency motor which is driven by a special worm gear and worm gear speed reducer, and the speed of the horizontal arm can be adjusted freely according to the welding requirements. The cross arm and the vertical column are all rectangular beam with large cross section, the cross section of the cross arm is 300 * 200, and the cross section of the column is 400 * 300. The guide rail processing uses the large-scale Longmen milling processing, has the machine to process the deformation quantity is small, the surface precision is higher.
The front end of the arm welding welding operation machine is equipped with electric cross adjusting mechanism, the torch alignment needs welding seam position, convenient adjustment. The top of the column is a horizontal arm lifting mechanism, which is driven by an AC brake motor to drive a worm gear and a worm reducer. Double insurance device using worm wheel and worm and AC brake motor. The other is provided with a ratchet bar mechanism in the guiding device, when the chain may be due to large external impact accidents (design safety factor of 10 times), ratchet ratchet bar mechanism will guide seat and arm lock on the post, to prevent cross arm fall accident.
Welding operator and other climbing ladders and other ancillary equipment to the top, to facilitate user access, and to ensure safety
