SU1512731A1 - Device for duplicating the joint line in welding - Google Patents

Abstract

The invention relates to welding production, and more specifically to devices for automatically copying a butt line by scanning. The device can be installed on various automatic welding machines when welding angular, butt-grooved edges and lap joints. The aim of the invention is to increase the reliability of the tracking device by simplifying its design. The device contains a copying mechanism (KM) and a rotary-locking mechanism (PFM). Simplification of the design is achieved by the fact that KM 10 is combined into one block with the PFM consisting of a cylinder with a groove and a piston, the openings of which are aligned with the groove of the cylinder. KM is inserted into the combined hole of the piston and the cylinder groove. The welding torch 13 is rigidly connected to KM 10. When air is supplied to the system through channels 18 and 24 KM, it is released, and the PFM, lowering, finds the butt line. When pressure is removed in the PFM system, the KM fixes, and with it the welding torch. 4 il.

The invention relates to welding production, and more specifically to devices for automatic copying of the butt line with tactile means, and is used for programmable arc welding on automatic machines or by means of angle rods, butt joints with grooved edges or snap joints.

The purpose of the invention is to increase reliability by simplifying the design of the device.

The device consists of fastened with a hand-t5 position. Since the profiles of the outer robot or automatic welding machine 1 of the surface of the sleeve 16 and the holes in the holder 2 with a parallel parallel 6 are made non-circular, it is possible the direction of welding axis 3, which is formed by the cylinder 4 with the groove 5 and the piston 6. In the cylinder 4, mounted with the carriage of the copying mechanism 10 is eliminated. When using the invention, there is no

The possibility of acting on the piston 6 through the need for constant monitoring of the cut stop 7 and the ball 8 spring 9. In the off-position of the welding head, which reduces the complexity of work, improves the work culture and the quality of welding. Rises

Versions of the piston 6 have a copying mechanism 10 with a fixed clamp 11 and an insulated sleeve 12 welding head 13, the flexible hose 14 of which 25 is real, since the number of interactions is supported by the sturdiness of the 15. parts in it is reduced.

Claims (1)

The copying mechanism consists of a sleeve. 16 with a hole 17 for supplying air through a hose 18, a piston 19 with a copying rod-probe 20 and a returnable and the reliability of the proposed device for copying the butt line during welding, containing the holder, is secured by a spring 21. The outer surface profile on the automatic welding machine, the copying The bone of the sleeve 16 is non-circular (for example, square) and repeats the profile of the hole in the piston 6. Compressed air to the piston 6 is supplied through the hole 22 of the holder 2 from the splitter 23 through the hose 24. The parts to be welded (Fig. 1) are indicated by 25. The device works as follows. In the absence of compressed air supply to the pistons 6 and 19, the sleeve 16 of the copying mechanism 10 is fixed (clamped) by the walls of the hole in the piston 6 and the groove 5. The clamping force is created by the spring 9. The stem-pin 20 under the action of the spring 21 is in the top (FIG. . 2) a mechanism that includes a sleeve connected to the duct, a spring-loaded piston with a rod mounted in the sleeve, a turning-fixing mechanism that includes a cylinder connected to the duct with a groove and a spring-loaded piston mounted in it, and a welding torch rigidly connected to the sleeve A copying mechanism, characterized in that, in order to increase the reliability of the device operation by simplifying its design, two coaxial holes are made in the piston walls of the rotary-locking mechanism, the axis of which is perpendicular Molecular forming the piston, and the replication mechanism sleeve is in ot40 position When a compressed impulse of the above-mentioned hole is supplied with air through the splitter 23, the axial movement of the pin and the pin 18, 24 and the holes 17, 22 to the pin holes 6c, when interacting with the walls of the stop 19, occurs, the rod extends sharply and opens the slot cylinder. probe 20 until the return spring 21 is fully compressed. At the same time, the pistol 6 moves to the left (Fig. 1) and the sleeve 16 of the copy mechanism 10 is unlocked. The stop 7 prevents the possibility of fixing the sleeve 16. The end of the probe-rod 20 of the unlocked copying mechanism 10 occupies a position in the center for cutting edges between the parts 25. The welding head 13 fixed on the sleeve 16 occupies the same position. After cessation of the air supply, the sleeve 16 of the copying mechanism 10 is fixed in a corrected position, and the stem-probe 20 occupies the original 0 5 position. Since the profiles of the outer surface of the sleeve 16 and the holes in the plate 6 are not circular, the possibility of rotation of the welding head 13 around position. Since the profiles of the outer surface of the sleeve 16 and the holes in the plate 6 are not circular, the possibility of rotation of the welding head 13 around the axis of the copying mechanism 10 is eliminated. When using the invention, there is no  the need for constant control over the position of the welding head, which reduces the number of components, since the number of interacting parts in it is reduced. and reliability of the proposed device for copying the welding line, containing a holder mounted on the welding machine, copying a mechanism including a sleeve connected to the duct, a spring-loaded piston with a rod mounted in the sleeve, a turning-fixing mechanism including a cylinder connected to the duct with a groove and a spring-loaded piston mounted in it, and a welding torch rigidly connected to the sleeve A copying mechanism, characterized in that, in order to increase the reliability of the device operation by simplifying its design, two coaxial holes, the axis of which is perpendicular, are made in the piston walls of the rotary-locking mechanism Forming piston, and the sleeve of the copying mechanism is set to 0 P sixteen 20 Figg Position in front of correction ag.Z Completion after norm) Phage.14
