Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to the technical field of bracket positioning when an EGR bracket is welded, and specifically is a novel bracket positioning welding device. Background Art

[0002] It is now necessary to weld a new type of bracket on the EGR side wall. One side of the bracket is trapezoidal and the other side is square. There is a high-precision connection hole in the middle of the trapezoidal side, and the square side is the welding connection area. Conventional welding positioning device designs mostly use external contour limiting, and a positioning block is set. A groove corresponding to the shape of the trapezoidal side is set on the positioning block, and a cylinder is set on one side of the positioning block to press the bracket into the groove. However, this type of limiting device has a disadvantage. The machining accuracy of the bracket shape is low and a large range of machining tolerances are set. If the positioning groove is set according to the standard size or minimum tolerance of the bracket shape, some qualified brackets that meet the maximum tolerance conditions will not be able to be inserted into the positioning groove. If the positioning groove is set according to the maximum tolerance of the bracket shape, the brackets that meet the standard size and minimum tolerance will be in a movable state in the positioning groove, which will affect the reliability of welding.

[0046] The utility model proposes a novel bracket positioning welding device, which is used in the welding positioning process. The bracket base plate 1, the inner positioning stop module 2, the lever cylinder 3 and the elastic outer contour limiting module 4 are particularly suitable for the positioning support of the novel bracket.

[0047] In general, the novel bracket positioning welding device proposed in the present invention mainly includes: bracket base plate 1, inner positioning stop module 2, lever cylinder 3 and elastic outer contour limiting module 4. Figure 1 , which shows the arrangement relationship of the bracket base plate 1, the inner positioning stop module 2, the lever cylinder 3 and the elastic outer contour limiting module 4.

[0048] The new bracket positioning welding device proposed by the present invention, when loading, presses one side of the bracket against the No. 2 limit plate 42 to press the protrusion 46 into the protrusion slot 44, and moves the other side of the bracket forward along the push block 410 until the trapezoidal side of the bracket presses against the No. 1 limit plate 41, and moves the bracket downward and left and right so that the bracket connecting hole can be sleeved on the connecting hole positioning boss 23, and drives the pressure plate in the lever cylinder 3 downward to press the bracket, so as to complete the limiting of the bracket on the bracket placement table 11, wherein the connecting hole positioning boss 23 and the magnet stop block 26 are adsorbed to ensure that the clamping positioning repeatability of each bracket is consistent, and the front and rear side walls of the bracket adopt an elastic positioning method, so that the protrusion 46 and the push block 410 serving as the positioning block can adapt to the bracket shape tolerance while locking it.

[0049] A bracket placement platform 11 is provided in the middle of one side of the top of the bracket base plate 1 through bolt connection. The outer diameter of the bracket placement platform 11 is smaller than the outer diameter of the bracket to be tested.

[0050] The above-mentioned inner positioning stop module 2 is arranged on the top of the bracket placement platform 11, and the inner positioning stop module 2 includes: a positioning groove 21, an inner positioning block 22, a connection hole positioning boss 23 and a limiting hole 25, wherein the positioning groove 21 is opened in the middle of the bracket placement platform 11, and the inner positioning block 22 is clamped in the positioning groove 21.

It should also be noted that the maximum outer diameter of the connection hole positioning boss 23 is the same as the minimum tolerance outer diameter of the connection hole in the bracket to be tested. The maximum outer diameter of the connection hole positioning boss 23 is set to the minimum tolerance outer diameter of the connection hole to ensure that the bracket with the minimum tolerance can also pass through the connection hole positioning boss 23. Because the connection hole has a high precision of at least ±0.05, a bracket with a connection hole with a maximum tolerance outer diameter can pass through the connection hole positioning boss 23 without causing a large position deviation.
