Description

Nut welding positioning tool

Technical Field

The utility model belongs to the technical field of welding auxiliary tools, and particularly relates to a nut welding positioning tool.

Background

As shown in fig. 1, various sheet metal brackets of an automobile are provided with nuts in a welded mode for facilitating installation of screws, and through holes are formed in positions where the nuts are arranged on the brackets for adapting to the length of the bolts, and the diameters of the through holes are larger than the diameters of the nuts. Because the sheet metal support of car is various, the structure is various, so the nut of prewelding is usually through manual placement nut and weld, and the workman is through the relative position between mode determination nut and the through-hole of looking at, strives for making nut and through-hole align to prevent that the bolt from contacting with the entity position of support and leading to the bolt unable thoroughly to fix. Since the position of the nut is confirmed by visual alignment, misalignment of the nut and the through hole often occurs, affecting final assembly.

Disclosure of utility model

In order to solve the defects in the prior art, the utility model provides the nut welding positioning tool which can be used for rapidly aligning the nut with the through hole on the bracket so as to improve the relative position precision between the nut and the through hole and improve the production efficiency.

In order to achieve the object of the utility model, the following scheme is adopted:

A nut weld locating tool comprising: the outer wall of the mandrel is provided with a plurality of spring pieces along the circumferential array, the front ends of the spring pieces are connected to the front ends of the mandrel, the rear ends of the spring pieces extend to the rear ends of the mandrel, a space is reserved between the spring pieces and the side wall of the mandrel, nuts are sleeved outside the mandrel and the spring pieces, and a plurality of nuts are arranged along the length direction of the mandrel.

The utility model has the beneficial effects that: the nut and the through hole are aligned by the mandrel, so that the nut and the through hole can be effectively prevented from being deviated, the adjusting process in visual operation is reduced, the aligning process of the nut can be quickened, and the welding efficiency is improved.

The marks in the figure: the spring comprises a mandrel-1, a spring piece-2, a circular ring-3 and a clamping groove-31.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the following detailed description of the embodiments of the present utility model will be given with reference to the accompanying drawings, but the described embodiments of the present utility model are some, but not all embodiments of the present utility model.

As shown in fig. 2 and 3, a nut welding positioning tool is provided, comprising: the mandrel 1, its outer wall is equipped with many spring pieces 2 along the circumference array, and the front end of spring piece 2 is connected in the front end of mandrel 1, and the rear end of spring piece 2 extends to the rear end of mandrel 1, and has the interval between the lateral wall of spring piece 2 and mandrel 1, and the outside of mandrel 1 and spring piece 2 is established to the nut cover, and spring piece 2 supports in the inner wall of nut to fix the nut, prevent that the nut from dropping, and the nut is equipped with a plurality ofly along the length direction of mandrel 1, so that prestore a plurality of nuts, in order to improve production efficiency.

When the metal plate bracket is used, the front end of the mandrel 1 is inserted into a through hole of the metal plate bracket, then a nut at the lowest end of the mandrel 1 is pressed on the surface of the bracket, the nut is welded and connected with the bracket by a welding gun, and then the mandrel 1 is pulled out; the mandrel 1 is utilized to align the nut with the through hole, so that the nut and the through hole can be effectively prevented from being deviated, the adjusting process in visual operation is reduced, the aligning process of the nut can be quickened, and the welding efficiency is improved.

Preferably, as shown in fig. 2, the mandrel 1 is sleeved with a ring 3 for pushing out the nut, and a clamping groove 31 is formed in the inner wall of the ring 3 for accommodating the spring piece 2, so that the spring piece 2 is prevented from being pressed towards the mandrel 1 by the ring 3, and the fixing effect of the spring piece 2 on the nut is lost.

Further preferably, the front end of the spring piece 2 is provided with a bending structure, the rear end of the spring piece 2 is in sliding contact with the outer wall of the mandrel 1, the distance between the inflection point of the bending structure and the axis of the mandrel 1 is larger than the radius of the small diameter of the nut and larger than the radius of the through hole, so that the nut can be stably clamped above the inflection point, and the nut is prevented from falling off in the process of taking the positioning tool. Because of the existence of the inflection point, the part of the spring piece 2 below the inflection point is in an inclined structure, and the inclined direction faces the outer side of the upper end of the mandrel 1, so that when the mandrel 1 is inserted into the through hole, the lower end of the spring piece 2 is firstly contacted with the edge of the through hole, and the spring piece 2 is extruded to be folded towards the middle by the inner wall of the through hole in the process that the mandrel 1 continuously descends, so that the mandrel 1 is aligned with the through hole, the nut is aligned with the through hole, and after the spring piece 2 is compressed towards the middle, the supporting function on the nut can be loosened, and the nut automatically falls; when the mandrel 1 is pulled out of the through hole, the spring piece 2 automatically returns to the elastic force again, and the nut is supported and fixed again.

Preferably, as shown in fig. 2, the upper end of the mandrel 1 is provided with a handle 11 to facilitate gripping and use.

The foregoing description of the preferred embodiments of the utility model is merely exemplary and is not intended to be exhaustive or limiting of the utility model. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model.
