The utility model provides a stud welding positioning tool.
The stud welding positioning tool is used for positioning a stud when the stud is welded on a target workpiece 200, so that the welding precision is improved.
In one embodiment, as shown in fig. 1, the stud welding positioning tool includes a tool body 110 and a fixing member 120.
The target workpiece 200 includes N stud welding areas, N positioning holes 111 corresponding to the positions of the N stud welding areas one to one are formed in the tool body 110, and N is an integer greater than or equal to 1. Each positioning hole 111 is used to provide a positioning function in stud welding to ensure that a stud can be welded to a designated position at a reasonable angle.
It should be understood that the technical solution of the present embodiment is mainly directed to the target workpieces 200 produced in small quantities, and for the target workpieces 200 produced in large quantities, since the workpiece structure will not be changed any more, the method is more suitable for manufacturing a special welding tool, and the welding precision is higher. For small-batch trial-manufactured workpieces, if a special welding tool is manufactured, and if the structure of the workpiece is changed, the cost for manufacturing the welding tool again is high.
In this embodiment, the tool body 110 and the target workpiece 200 have the same shape and size in at least the stud welding region and the fixing region.
For the target workpiece 200, stud welding is required to be performed in a stud welding area, and for the tool body 110, the positioning hole 111 is formed in a position corresponding to the stud welding area; and the tool body 110 and the target workpiece 200 are fixed at their respective fixing regions. The shapes and sizes of the tool body 110 and the target workpiece 200 may be the same or different in the regions other than the stud welding region and the fixing region.
In one embodiment, the tool body 110 may be directly fabricated by forming a positioning hole 111 in a target workpiece 200.
When a target workpiece 200 to be welded is selected as a raw material to manufacture the tool body 110, the cost is relatively low, meanwhile, the manufactured tool body 110 is relatively high in consistency with the target workpiece 200, as long as the positioning hole 111 is formed in the position where the stud needs to be welded, when the stud passes through the positioning hole 111 to be welded, the accuracy of the stud welding position can be improved, and the possibility that the stud is welded at the specified position is improved.
When the tool is used, as shown in fig. 1, the tool body 110 is fixed to the target workpiece 200 through the fixing member 120, so that the tool body 110 and the target workpiece 200 are overlapped, and thus, an area on the target workpiece 200, which can be observed through the positioning hole 111, is a stud welding area. By fixing the tool body 110 and the target workpiece 200 by the fixing member 120, relative movement between the tool body and the target workpiece can be avoided, thereby improving the accuracy of stud welding positioning.
The embodiment of the utility model provides a through providing frock body 110, can improve the welding precision when carrying out stud welding on target work piece 200. Because the size and the shape of the tool body 110 are the same as those of the target workpiece 200, the target workpiece 200 can be directly used as a material to manufacture the tool body, so that the structural consistency between the target workpiece 200 and the tool body 110 is ensured, and meanwhile, the cost is reduced.
In one embodiment, the fixture body 110 and the target workpiece 200 are respectively provided with fixing holes 112 corresponding to each other in position, and the fixing member 120 fixes the fixture body 110 and the target workpiece 200 through the fixing holes 112. In practice, the fixing member 120 passes through the fixing hole 112, so that the positions of the tool body 110 and the target workpiece 200 are overlapped, and the corresponding positions are overlapped, thereby improving the positioning accuracy in the welding process.
Further, as shown in fig. 2 and 3, the fixing member 120 includes a positioning pin 121, and the positioning pin 121 includes a gap portion 1211 and a positioning portion 1212; the number of the positioning portions 1212 is two, and the two positioning portions 1212 are respectively located at two sides of the gap portion 1211, the diameter of the gap portion 1211 is larger than that of the positioning portions 1212, so that the gap portion 1211 can be clamped by the fixing hole 112, and the positioning portions 1212 can pass through the fixing hole 112; the two positioning portions 1212 are respectively inserted into the fixing hole 112 of the tool body 110 and the fixing hole 112 of the target workpiece 200.
As shown in fig. 2 and 3, it is understood that the gap 1211 has a certain thickness, and the thickness of the gap 1211 may be set according to circumstances, and in one embodiment, when the target workpiece 200 is a sheet metal member, the thickness of the gap 1211 is set to be 1 to 5 mm, and specifically, may be various values such as 3 mm or 4 mm.
Alternatively, the thickness of the gap 1211 is 1 to 5 mm. Thus, a certain gap is formed between the tool body 110 and the target workpiece 200, and the positioning accuracy of the stud is improved.
Optionally, the fixing element 120 further includes a pressing block 122, the positioning pin 121 further includes two connecting portions 1213 matching with the pressing block 122, the number of the connecting portions 1213 is two, the two connecting portions 1213 are respectively located on one side of the two positioning portions 1212, which is away from the gap 1211, and the pressing block 122 is connected to the connecting portions 1213 to fix the target workpiece 200 and the tool body 110.
It can also be understood that the two connecting portions 1213 are respectively located on the sides of the two positioning portions 1212 away from the gap 1211 and extend in the direction away from the gap 1211.
Specifically, the connecting portion 1213 may be a threaded structure, and the pressing block 122 is provided with a corresponding screw hole, so that the pressing block 122 and the positioning pin 121 are connected by matching the screw thread and the screw hole, and thus, the target workpiece 200 and the tool body 110 may be relatively firmly fixed together by the fixing member 120, which is beneficial to improving the positioning accuracy.
Optionally, the fixing hole 112 may be reused for the fabrication holes on the tool body 110 and the target workpiece 200. It should be understood that if holes are additionally formed on the target workpiece 200 and the tool body 110, on one hand, the accuracy of the hole-forming position is difficult to be ensured, and on the other hand, the strength of the target workpiece 200 may be affected, so that in the present embodiment, the original fabrication holes are reused as the fixing holes 112, which may be fabrication holes required in the manufacturing process of screw holes, lightening holes, and the like, which is helpful to improve the positioning accuracy and simplify the process.
The number of the fixing holes 112 can be selected according to actual conditions, generally, at least three fixing holes are selected, and the positioning effect is improved by triangular positioning, and obviously, if the size of the target workpiece 200 is larger, the number of the fixing holes 112 can be increased appropriately.
Further, in order to improve the positioning accuracy in the stud welding process, a guide tube 130 is further arranged, and the guide tube 130 is arranged in the positioning hole 111 in a penetrating mode and in interference fit with the positioning hole 111.
As shown in fig. 4, the magnitude relationship between the inner diameter Φ 1 of the guide tube 130 and the outer diameter Φ 2 of the stud welding gun 300 corresponding to the stud to be welded satisfies: phi 2 is less than phi 1. That is, the stud welding gun 300 has an outer diameter slightly smaller than the inner diameter of the guide tube 130 so that the stud welding gun 300 can pass through the guide tube 130 and weld a stud at a designated position on the target workpiece 200, which contributes to further improvement in positioning accuracy for the welding process by providing the guide tube 130.
However, the inner diameter of the guide pipe is not too large, and in the embodiment, the size relationship between the inner diameter φ 1 of the guide pipe 130 and the outer diameter φ 2 of the stud welding gun 300 corresponding to the stud to be welded satisfies the following conditions: phi 1 is less than or equal to phi 2+3 mm. If the inner diameter is too large, there may be some movement margin in the position of the stud gun 300, which may affect the positioning accuracy. During implementation, one or two of the inner wall of the positioning hole 111 and the outer wall of the guide pipe 130 can be polished by sand paper, so that the matching effect is improved, and the positioning precision is improved.
Optionally, the guide tube 130 is an insulating guide tube 130, and the tool body 110 is an insulating tool body 110.
Since the working principle of the stud welding gun 300 is to weld the entire end surface of the metal stud on the target workpiece 200 by instantly pressurizing and discharging the metal stud, in order to improve the safety degree, the guide tube 130 in this embodiment is an insulating guide tube 130, and may be specifically made of PVC (polyvinyl chloride) or other materials, the length of the guide tube 130 should not be too long, and should not be too short, which may affect the positioning accuracy, and the too long may affect the convenience degree of the welding operation. In this embodiment, the thickness may be set to about 15 to 25 mm.
Similarly, the tool main body 110 may also be subjected to an insulation process, for example, an insulation material may be coated or an insulation layer may be bonded near the positioning hole 111 of the tool main body 110, which is beneficial to improving safety.
As shown in fig. 4, when the tool is used, the tool body 110 and the target workpiece 200 are fixed together by the fixture 120, and then the stud is welded to the target workpiece 200 along the guide pipe 130 by the stud welding gun 300.
The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
