Technical field
The utility model relates to a kind of welding drift, relates in particular to a kind of bolt and wire bonds drift that is applicable to bolt and wire bonds.
Background technology
At present, the operation of bolt and wire spot welding is: 1, screw is put into low punch; 2, wire is placed on above bolt; 3, push down on the pedal, complete a spot welding.1), after bolt completes with wire bonds but there is following problem:, often burn in various degree can occur the screw thread of bolt; 2) often easily there is sealing-off in the molybdenum bar, on drift, usually needs again to weld molybdenum bar in welding process, and then the operating efficiency of the normal welding of impact.Process Reflection and analysis, reason is as follows: the design of (1) welding drift is unreasonable, and when spot welding, the screw thread of bolt easily touches the inwall of drift, thereby causes short circuit, produces spark, causes screw thread burn, and then affects the product quality after having welded; (2) drift completes by soldering with the connection of molybdenum bar, and when bolt welds mutually with guiding, drift and welding position can heat up rapidly, and time one length can cause sealing-off, cannot continue to use, and need to again weld molybdenum bar.
Utility model content
For this reason, when technical problem to be solved in the utility model is in prior art bolt and wire bonds, the screw thread of bolt is easily touched drift inwall and is burnt, and molybdenum bar easily comes off from drift, and then a kind of screw thread burn of preventing is provided, and the bolt of molybdenum bar difficult drop-off and wire bonds drift.
For solving the problems of the technologies described above, a kind of bolt of the present utility model and wire bonds drift, it comprises drift, the molybdenum bar being weldingly connected with described drift upper end end face, the upper surface of described drift forms and is applicable to the groove that described molybdenum bar embeds, and the upper end sidewall of described groove extends inwardly to the upper surface of putting up at described molybdenum bar, and on described drift, axial direction forms inner chamber, described interior cavity inner sleeve is provided with insulating element.
Described groove becomes " L " type, and " L " type minor face of described groove straight down, and long limit laterally arranges inwardly, and described molybdenum bar is " L " type consistent with described groove, and is weldingly connected with described drift upper surface.
The width dimensions that the upper end lateral wall of described groove is put up on described molybdenum bar equals described molybdenum bar bond length size.
The lower contact jaw of described insulating element and described drift is outward extended with outer portion, and described insulating element is fastened in described drift inner chamber by described outer portion and the cooperatively interacting of draw-in groove that be molded over described drift inner chamber lower end.
Described insulating element is made by carbon piece.
Described drift adopts copper rod to make.
Technique scheme of the present utility model has the following advantages compared to existing technology:
(1) in the utility model, the upper surface of described drift forms and is applicable to the groove that described molybdenum bar embeds, and the upper end sidewall of described groove extends inwardly to the upper surface of putting up at described molybdenum bar, make so described molybdenum bar can be fixed on firmly on described drift, the firmness of described molybdenum bar can not be subject to the impact of high temperature, and described molybdenum bar can not come off because of the relation of service time yet; Meanwhile, in the utility model, on described drift, axial direction forms inner chamber, and described interior cavity inner sleeve is provided with insulating element, and arranging of described insulating element can prevent that screw is damaged because of touching in drift inwall in welding process.
(2) in the utility model, on described drift, axial direction forms inner chamber, described interior cavity inner sleeve is provided with insulating element, the width dimensions that the upper end lateral wall of described groove is put up on described molybdenum bar equals described molybdenum bar bond length size, the setting of the upper end lateral wall of described tongue can guarantee that described molybdenum bar does not come off from described drift, can guarantee that again described molybdenum bar can be arranged in described groove smoothly.
(3) in the utility model, on described insulating element, also form outer portion, described insulating element is fastened in described drift inner chamber by described outer portion and the cooperatively interacting of draw-in groove that be molded over described drift inner chamber lower end, arranging of described outer portion can avoid described insulating element to come off, and described insulating element can be firmly set in the inner chamber of described drift.
(4) in the utility model, described insulating element is made by carbon piece, and the cost of its manufacturing is low.
Accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, according to specific embodiment of the utility model also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is drift schematic cross-section described in the utility model.
In figure, Reference numeral is expressed as: 1-drift; 2-insulating element; 3-molybdenum bar.
The specific embodiment
Below with reference to accompanying drawing, use following examples to be further elaborated the utility model.
As shown in Figure 1, a kind of bolt described in the present embodiment and wire bonds drift, it comprises drift 1, the molybdenum bar being weldingly connected with described drift 1 upper end end face, the upper surface of described drift 1 forms and is applicable to the groove that described molybdenum bar embeds, and the upper end sidewall of described groove extends inwardly to the upper surface of putting up at described molybdenum bar, on described drift 1, axial direction forms inner chamber, and described interior cavity inner sleeve is provided with insulating element.In the present embodiment, described molybdenum bar adds welding mode to inlay is fixedly connected on the upper end of described drift 1, make so described molybdenum bar can be fixed on firmly on described drift 1, the firmness of described molybdenum bar can not be subject to the impact of high temperature, and described molybdenum bar can not come off because of the relation of service time yet; Meanwhile, in the present embodiment, on described drift 1, axial direction forms inner chamber, and described interior cavity inner sleeve is provided with insulating element, and arranging of described insulating element can prevent that screw is damaged because of touching in described drift 1 inwall in welding process.
