The compound gap adjusting mechanism consists of a gap self-adjusting flange, a gap adjusting belleville spring and a gap adjusting lock nut. The adjustable workpiece supporting mechanism consists of a workpiece bracket shaft and a gap adjusting ball jackscrew. The compound gap self-adjusting flange ring welding jig provided by the invention has the advantages and positive effects that positioning control is convenient, and the defect that pointing of a welding gun is passively changed due to the variation in thickness of every flange to be welded is mainly overcome. The welding quality is obviously improved, and welding lines are fair in appearance; the planeness of every flange after being welded is well ensured; the consistency is good; and the work efficiency is improved.
Description
Technical field
The invention belongs to flange ring welding clamp technical field, especially relate to the flange ring welding clamp that a kind of compound gap regulates automatically.
Background technology
In the prior art, most producer is when being welded with the flange of tube connector.Flange clamps in location, boxing special plane driving head side, its welding gun welding method clamping area.Welding gun and the welded position of flange are fixing, and that is welding gun points to is constant.Because the thickness of flange changes in the margin of tolerance, therefore welding gun and the welded position of flange are actually and are changing in the margin of tolerance. and bad when making seam flange change fashion with flange thickness.Product competitiveness is commercially declined, has a strong impact on the uniformity of welding and the outward appearance of weld seam.
Summary of the invention
The problem to be solved in the present invention is to provide that a kind of structure is simple, easy to operate, production efficiency is high, and welding gun is pointed to by the flange ring welding clamp that any a kind of compound gap affected of welded flange thickness tolerance regulates automatically.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the flange ring welding clamp that a kind of compound gap regulates automatically, comprise closed force application mechanism, compound gap adjusting mechanism and adjustable supporting piece mechanism, compound gap adjusting mechanism is fixed on front side of closed force application mechanism by adjustable supporting piece mechanism.
Further, described closed force application mechanism is made up of adpting flange, fixture adpting flange, eccentric shaft, power transmission flange and clamp system back-moving spring before eccentric shaft fixed head, fixture, two eccentric shaft fixed heads connect respectively by eccentric shaft bolt of fixing plate between adpting flange and fixture adpting flange before fixture, two eccentric shaft fixed heads are positioned at the two ends of eccentric shaft, power transmission flange is positioned on front side of eccentric shaft, and clamp system back-moving spring is fixed on the front side of power transmission flange.
Further, described compound gap adjusting mechanism is made up of the automatic regulating flange in gap, gap adjustment butterfly spring and gap adjustment locking nut, and gap adjustment butterfly spring is between the automatic regulating flange in gap and gap adjustment locking nut.
Further, adjustable supporting piece mechanism is made up of work supporting block axle and gap adjustment ball jackscrew, and gap adjustment ball jackscrew is located on work supporting block axle, towards the side for the treatment of boxing flange.
The advantage that the present invention has and good effect are: the first, owing to adopting technique scheme, are convenient to positioning control, mainly overcome the change of welded flange thickness and the welding gun that causes points to passive change.Obvious lifting welding quality, weld appearance fairing; Secondly, well ensure that the flatness after flange welding, uniformity is good; 3rd, improve operating efficiency; It is simple that the present invention has structure, and easy to maintenance, processing cost is low, production efficiency advantages of higher.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the flange ring welding clamp that a kind of compound gap of the present invention regulates automatically, it is characterized in that: comprise closed force application mechanism, compound gap adjusting mechanism and adjustable supporting piece mechanism, compound gap adjusting mechanism is fixed on front side of closed force application mechanism by adjustable supporting piece mechanism.
Described closed force application mechanism is made up of adpting flange 1, fixture adpting flange 2, eccentric shaft 5, power transmission flange 10 and clamp system back-moving spring 8 before eccentric shaft fixed head 4, fixture, two eccentric shaft fixed heads 4 connect respectively by eccentric shaft bolt of fixing plate 3 between adpting flange 1 and fixture adpting flange 2 before fixture, two eccentric shaft fixed heads 4 are positioned at the two ends of eccentric shaft 5, power transmission flange 10 is positioned on front side of eccentric shaft 5, and clamp system back-moving spring 8 is fixed on the front side of power transmission flange.
Described compound gap adjusting mechanism is made up of the automatic regulating flange 11 in gap, gap adjustment butterfly spring 9 and gap adjustment locking nut 12, and gap adjustment butterfly spring 9 is between the automatic regulating flange 11 in gap and gap adjustment locking nut 12.
Adjustable supporting piece mechanism is made up of work supporting block axle 6 and gap adjustment ball jackscrew 7, and gap adjustment ball jackscrew 7 is located on work supporting block axle 6, towards the side for the treatment of boxing flange 14.
The adjustable supporting piece mechanism of the present invention's two groups of work supporting block axles 6 and gap adjustment ball jackscrew 7 composition, holds up and treats that boxing flange 14 makes it centre bore and presses close to power transmission flange 10 centralized positioning boss.When moving wrench makes eccentric shaft 5 eccentric driven forward power transmission flange 10 travel forward, its center positioning boss first treats boxing flange 14 centering and pushed forward treats that boxing flange 14 is close to the tension hook compression of eccentric shaft fixed head 4, and the direct-connected adapter 13 of boxing treated by dress afterwards.After hold out against and treat that the direct-connected adapter 13 of boxing is felt relieved location.Now treat that the surface to be welded of boxing flange 14 leans against the location, tension hook front side of eccentric shaft fixed head 4 all the time; No matter how flange thickness changes, and welding bead anchor point 16 hooks side in the tension of eccentric shaft fixed head 4 all the time, welds with welding gun 15.
The function of gap adjustment disk spring 9 is: the automatic regulating flange in gap 11 holds out against at the eccentric driven forward of eccentric shaft 5 and treats boxing flange 14 under pre-tension; When boxing flange 14 is in negative common difference, the automatic regulating flange 11 in gap extends and discharges pretightning force, holds out against and treats boxing flange 14; When boxing flange 14 is in plus tolerance, the automatic regulating flange 11 in gap shortens, and holds the eccentric thrust of eccentric shaft 5, holds out against and treat boxing flange 14; Make to treat that boxing flange 14 welds all the time under stress.
Clamping of the present invention and reset are completed by eccentric shaft 5 and clamp system back-moving spring 8: when moving wrench makes eccentric shaft 5 bias forward, then promotion power transmission flange 10 travels forward and holds out against flange 14 to be welded; When moving wrench makes eccentric shaft 5 bias backward, under the promotion of clamp system back-moving spring 8 and gap adjustment disk spring 9 stretching force, the automatic regulating flange 11 of power transmission flange 10 and gap moves backward; Unclamp fixture, take out workpiece.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
