Abstract
The utility model relates to a kind of welding bottom hole structure of stamping parts, described stamping parts offers welding bottom outlet, grafting certain position pin in described welding bottom outlet, and described shop bolt is welded on this stamping parts, it is characterized in that, described welding bottom outlet is closed pore structure, described welding bottom outlet is by the first horizontal segment being positioned at top, be positioned at the second horizontal segment of bottom, vertical linkage section and arc linkage section are formed, the side of described vertical linkage section between described first horizontal segment and the second horizontal segment, the opposite side of described arc linkage section between described first horizontal segment and the second horizontal segment.The welding bottom hole structure of stamping parts of the present utility model, can improve weld strength and the precision of shop bolt and stamping parts.
Description
Technical field
The utility model relates to a kind of welding bottom hole structure of stamping parts.
Background technology
Along with the fast development of automobile industry, the popularity of automobile is also more and more higher.But the competition in industry is also growing more intense, so how to ensure the most important thing that product quality becomes enterprise and depends on for existence.The welding of securing member has direct impact for the quality of whole welding, and the precision after how ensureing to weld and intensity, to the quality important of product.
Refer to Fig. 1 and Fig. 2, conventional stamping parts 1' offer welding bottom outlet 2', in welding bottom outlet 2', a shop bolt 3' is set, the first projection welding of shop bolt 3' on stamping parts 1', arc-welding more afterwards; Shop bolt is had to the requirement of intensity and precision; Conventional welding bottom outlet 2' is open type pore structure, welding bottom outlet 2' is made up of the arc linkage section 23' on the first horizontal segment 21' at top, the second horizontal segment 22' in bottom and the right side between the first horizontal segment 21' and the second horizontal segment 22', because welding bottom outlet 2' is open type, shop bolt 3' position degree deviation after projection welding, arc-welding is large, can not meet design requirement.
Summary of the invention
The purpose of this utility model, exactly in order to solve above-mentioned prior art Problems existing, and provides a kind of welding bottom hole structure of stamping parts, can promote stability and the precision of shop bolt welding.
The technical scheme realizing above-mentioned purpose is: a kind of welding bottom hole structure of stamping parts, described stamping parts offers welding bottom outlet, grafting certain position pin in described welding bottom outlet, and described shop bolt is welded on this stamping parts, it is characterized in that, described welding bottom outlet is closed pore structure, described welding bottom outlet is by the first horizontal segment being positioned at top, be positioned at the second horizontal segment of bottom, vertical linkage section and arc linkage section are formed, the side of described vertical linkage section between described first horizontal segment and the second horizontal segment, the opposite side of described arc linkage section between described first horizontal segment and the second horizontal segment.
The welding bottom hole structure of stamping parts of the present utility model, promotes stability and the precision of shop bolt welding; Also improve welding operation simultaneously, improve welding efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the welding bottom hole structure of conventional stamping parts;
Fig. 2 is the welding bottom hole structure schematic diagram that shop bolt is welded on the stamping parts of the routine of Fig. 1
Fig. 3 is the structural representation of the welding bottom hole structure of stamping parts of the present utility model;
Fig. 4 is the structural representation that shop bolt is welded on the welding bottom hole structure of stamping parts of the present utility model.
Detailed description of the invention
In order to make those skilled in the art can understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 3 and Fig. 4, embodiment of the present utility model, a kind of welding bottom outlet 2 structure of stamping parts 1, stamping parts 1 offers welding bottom outlet 2, grafting certain position pin 3 in welding bottom outlet 2, and shop bolt 3 is welded on this stamping parts 1, welding bottom outlet 2 is closed pore structure, welding bottom outlet 2 is by the first horizontal segment being positioned at top, be positioned at the second horizontal segment of bottom, vertical linkage section and arc linkage section are formed, the side of vertical linkage section between described first horizontal segment and the second horizontal segment, the opposite side of arc linkage section between the first horizontal segment and the second horizontal segment.
Welding bottom outlet 2 structure of stamping parts 1 of the present utility model, change the open type structure of the welding bottom outlet of the stamping parts of routine into closed pore structure, in use, shop bolt 3 is first plugged in this welding bottom outlet 2, and then be welded on stamping parts 1, the welding sequence of shop bolt 3 is first projection welding, afterwards arc-welding again, effectively can improve welding quality and the welding precision of pin through this optimization of verification experimental verification, promotes stability and the precision of the welding of shop bolt; Also improve welding operation simultaneously, improve welding efficiency.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
