Free adjustment clamp for welding
The utility model discloses welding jig technical field specifically is a welding is with freely adjusting fixture.
In the welding process, when a welding seam is positioned at different welding positions, a molten pool is influenced differently by various forces (such as arc blowing force, electromagnetic force, molten iron gravity, surface tension and the like), and the operation difficulty of welders is different, so that the welding position of the welders is changed by a tool clamp, the welding seam is positioned at a flat welding position or a transverse welding position to the greatest extent, the operation difficulty is reduced, and the welding seam quality is ensured. When the existing pipe fitting products are welded, because the number of sub-parts is large, the product structure is complex, the number of welding seams is large, and the positions are different. A product often needs to be provided with a plurality of fixtures to ensure that each welding line is welded at an ideal position, so that the workload of a welder is greatly increased, the tool fixtures need to be replaced for many times, workpieces are repeatedly clamped, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a welding is with freely adjusting anchor clamps to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a welding is with freely adjusting anchor clamps, includes the connecting rod, the upper end welding of connecting rod has the product support, the sleeve pipe has been cup jointed to the outside of connecting rod, the welding of sheathed tube lower extreme has first disc, the second disc is installed through the bolt to first disc, the downside welding of second disc has branch, the bolt is located the middle part of first disc, second disc.
Preferably, the product support is a rectangular box structure with an open upper opening, a threaded hole for fixing a workpiece is formed in the product support, and the connecting rod is in clearance fit with the inner cavity of the sleeve.
Preferably, the upper end of the sleeve is welded with a thrust washer, and the connecting rod is a solid shaft and the upper end of the connecting rod is provided with a thinned journal.
Compared with the prior art, the beneficial effects of the utility model are that: because the connecting rod can rotate automatically and can also rotate relative to the supporting rod, the clamp can conveniently enable a workpiece to be in the best welding position, the formability of a welding seam is good, the process defect is obviously reduced, and the welding speed is improved; most welding seams can be welded only by using one clamp, heavy work of repeated carrying, positioning, clamping, tool changing and the like is reduced, the working efficiency is improved, and the labor condition of workers is improved; a plurality of positions can be welded by one pair of fixtures, the number of the fixture needing to be equipped is reduced, the cost is reduced, the number of the fixtures is reduced, and the storage space and the site are saved.
FIG. 1 is a schematic front view of the present invention;
FIG. 2 is a schematic side view of the present invention;
fig. 3 is a schematic view of the side structure of the present invention.
In the figure: 1. a connecting rod; 2. a strut; 3. a first disc; 4. a sleeve; 5. a thrust washer; 6. a product support; 7. a bolt; 8. a second disk.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a welding is with freely adjusting anchor clamps, includes connecting rod 1, the upper end welding of connecting rod 1 has product support 6, sleeve pipe 4 has been cup jointed to connecting rod 1's outside, the lower extreme welding of sleeve pipe 4 has first disc 3, second disc 8 is installed through bolt 7 to first disc 3, the downside welding of second disc 8 has branch 2, bolt 7 is located the middle part of first disc 3, second disc 8.
Specifically, the product support 6 is a rectangular box structure with an open upper opening, a threaded hole for fixing a workpiece is formed in the product support 6, and the connecting rod 1 is in clearance fit with the inner cavity of the sleeve 4.
Specifically, the upper end of the sleeve 4 is welded with a thrust washer 5, and the connecting rod 1 is a solid shaft and the upper end of the connecting rod is provided with a thinned journal.
The working principle is as follows: the supporting rod 2 of the two-axis deflection clamp is inserted into a rotary positioner, the three-jaw chuck of the positioner is tightly connected, a product support 6 of the workpiece fixture is fixed, the bolt 7 is unscrewed to adjust the included angle between the supporting rod 2 and the sleeve 4, and when the supporting rod 2 is parallel to the connecting rod 1, the annular welding joint of a main pipe of the workpiece and a flange can be welded; when the supporting rod 2 and the connecting rod 1 form a certain angle, the welding rod can be used for welding a circumferential welding seam of a main pipe and a branch pipe of a workpiece; through the rotary connecting rod 1, the circumferential welding seams of the branch pipes and the main pipe at different positions can be welded, and the rotary connecting rod can be freely adjusted, and is flexible and convenient.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
