Abstract

A T-shape pipe automatic welding machine for welding T-shape pipe welding seam belongs to machinery field. Two orthometric machinery convex wheels are arranged on a welding torch moving structure. The revolve of the welding torch is driven by a servo motor, therefore, the utility model achieves three-dimensional supplement movement of the welding torch relative to the T-shape pipe welding seam and can complete the automatic welding of the T-shape pipe welding seam in a welding cycle by adopting PLC control. Because a horizontal convex wheel of the welding torch moving mechanism is provided with an eccentric distance relative to the rotation center of the welding torch, therefore, the welding torch can complete the 180 degrees welding seam welding process of one side of the T-shape pipe welding seam in rotation range of less than 180 degrees, thereby solving the interfere problem between the welding torch and the neighborng welding pipe to achieve the full automatic continuous welding of the T-shape pipe groupware.

Description

T type pipe automatic welding machine

Technical field

T type pipe automatic welding machine of the present utility model belongs to mechanical field, relates in particular to the continuous automatic soldering device that welds at T type pipe weld seam in the similar welding procedure with other of a kind of new radiator technological process of production.

Background technology

At present at home for the relatively large T type pipe weld seam welding of different purposes production lots, except the higher enterprise of indivedual welding jig levels, manufacturing company adopt the industrial welding robot welding, all the other manufacturers all adopt the manual electric arc welding to connect or gas is protected welding, the welding procedure level error, welding productivity is low, and welding quality depends on welder's technical merit fully.Adopt the industrial welding robot to be engaged in the welding of this single type, though welding quality, production efficiency are indubitable, equipment investment is big, operating cost is high, bombards mosquito and wastes one's talents just as shooting high.The automatic soldering device that the efficient high-quality of development low price, low operating cost and energy is finished the continuous welding of various T type pipe weld seam is unsolved for a long time technical barrier.

Summary of the invention

In order to change this present situation, allow general medium-sized and small enterprises can both can afford usefulness on, the utility model provides a kind of special-purpose low price T type pipe automatic welding machine.This welder not only can replace the artificial welding of this type, improves the welding quality and the welding efficiency of T type pipe effectively, and can satisfy the T type tube welding process requirement of different Guan Jing, different casts very easily by changing a small amount of annex.

The technical scheme that its technical problem that solves the utility model adopts is:

In the feeler mechanism of T type pipe weld seam, adopt two on orthogonal direction, to change the mechanical cam that to realize that the difference cover moves according to certain rules, with a servo rotating mechanism that can satisfy welding process requirement, PLC or Single-chip Controlling are adopted in this servo control mechanism and complete machine operation, thereby realize the automatic welding of T type pipe weld seam (being three-dimensional welding track).The utility model adopts can obtain good welding effect from mixed gas protected consumable-electrode weld.

The beneficial effects of the utility model are: 1, generally adopt the manual welding present situation at domestic T type pipe welding, use it can effectively improve the technological level and the automaticity of this type welding.2, need only change the welding requirements that cam face just can adapt to user's different tube diameters, difformity T type pipe very easily.3, because device-specific is strong, simple in structure, thereby make its cost significantly reduce (relatively welding robot), make rising that general medium-sized and small enterprises can both use.

The specific embodiment

In Fig. 1, vertical welded tube (1), the interspersed formation of horizontal welded tube (2) T type pipe joint to be welded, torch handle (4) is fixed on the welding gun fixed mount (5) with angle adjustment worker energy, and robbing head (3) by miniature swing mechanism (28) to welding gun provides according to the welding campaign of certain amplitude with warble (to adapt to different weld width requirements).Welding gun fixed mount (5) is rigidly connected with vertical guide plate (6), vertical guide plate (6) is connected with L type link (27) by director element (7), the lower end of vertical guide plate (6) is connected with turning rolls (8), owing to the roller (9) of the deadweight vertical guide plate of reason (6) lower end is pressed on the working surface of cam A (10) all the time, as shown in Figure 2: cam A (10) is that one section pivot with turning arm (21) is the center of circle, with the distance to roller A (9) is the annulus of radius, and its working surface is the upper surface of this section annulus.When L type link (27) rotates in company with turning arm (20), cam A (10) vertically height change will rob head (3) to welding gun and provide a difference that vertically goes up to mend motion.L type link (27) is connected with turning arm (20) by director element (26), T type link (23) is fixed on the bottom surface of L type link (27), spring retainer (25) is connected with turning arm (20), the turning rolls (22) that stage clip (24) is gone up connection with T type link (23) is pressed to cam B (19), because the restoring force of stage clip (24) makes roller (20) press to the working surface of cam B (19) all the time, as shown in Figure 2: cam B (19) is the disk that and turning arm (21) pivot have certain eccentric throw, one section working surface that periphery is cam B (19) that this disk contacts with roller B (21).When turning arm (20) when rotating, the radially lift variation of cam B (19) provides a horizontal moving interpolation that changes along turning arm (20) center line with regard to robbing head (3) for the welding gun that is fixed on the L type link (27).Moving interpolation on two orthogonal directions (promptly vertical, horizontal direction) and turning arm (20) rotatablely move and just synthesize welding gun and rob head (3) and finish T type pipe three-dimensional weld seam and weld needed movement locus.

In the embodiment shown in fig. 1, turning arm (20) is connected with multidiameter (18), and multidiameter (18) is connected with base plate (11) by bearing group (16) and bearing holder (housing, cover) (17), and multidiameter (18) is connected with servomotor (12) by synchronous cog belt.

In the embodiment shown in fig. 1, servomotor (12) is by PLC (or single-chip microcomputer) control, and PLC drives turning arm (20) by welding process requirement by servomotor (12) and rotates.

In the embodiment shown in fig. 1, turning arm (20) is in rotary course, because the interpolation displacement on two orthogonal directions that welding gun rifle head (3) has obtained to be provided by cam A (10), cam B (18), thereby make it finish the welding processing of T type pipe three dimensions weld seam exactly along the three-dimensional weld seam welding of T type pipe.Because the welding gun that is arranged so that of eccentric distance e just can be finished the i.e. welding processing of 180 degree weld seams of T type pipe weld seam one side in the rotating range of 180 degree, thereby solved the interference problem of welding gun, made T type pipe weld seam realize that full-automatic continuous welding becomes possibility with contiguous weldment.In addition, welding machine is after finishing T type pipe single face automatically welding is the half cycle welding, and the upset of the automatic turning mechanism by workpiece just can realize the complete cycle welding processing of T type pipe weld seam.
