Embodiment 1

[0019] Such as figure 1 shown.

[0020] A special spot welding connection device suitable for titanium alloy plates, which includes a base 1, a column 2, a fixed round rail 3, a tool driving device 4, a spring steel wire rope 5, a tool track 6, a tool 7, a clamping block I8, and a clamping block II9 , Piston 10. The column 2 is equipped with a tool drive device 4 and a tool guide rail 6 that can move up and down to adapt to the connection of different thickness base materials. The tool guide rail 6 is equipped with a tool 7, and the tool 7 is connected to the tool drive device 4. The tool drive device 4 can be conventional The motor can also be a cylinder. When the cylinder is used, the cutter and the cylinder can be connected through the connecting rod 5. The cylinder drives the connecting rod 5 to drive the cutter 6 to impact the pin 11 to realize rapid stamping and cutting. When the motor is used, the cutter can be driven to align the pin 11 is milled, and the cutter 7 ca...

Embodiment 2

[0022] A special spot welding connection method for titanium alloy plates, which utilizes figure 1 The shown device is realized. First, a through hole 14 is drilled on the workpiece I12, and a blind hole 15 is drilled on the workpiece II13. The diameter of the through hole 14 and the blind hole 15 are the same; then the workpiece I12 and the workpiece II13 are placed on the base 1 and Fix it, then open the clamping block I8 and clamping block II9, install the threaded pin 11, the material of the threaded pin 11 is consistent with the base material to be connected, and the diameter of the pin is larger than the diameter of the through hole 14 and the blind hole 15 , the outer side of the pin has a fine thread, then clamp the clamping block Ⅰ8 and the clamping block Ⅱ9, combine the piston 10 with the upper end of the clamping block Ⅰ8 and the clamping block Ⅱ9, and drive the piston to rotate and downward through the motor. Move, let the threaded pin 11 continuously squeeze into ...

Abstract

The invention discloses a special spot welding connection device and method suitable for a titanium alloy sheet. The device is characterized by comprising a base, a stand column, a fixed cylindrical track, a pressure device, a spring steel wire rope, a tool track, a tool, a clamping block I, a clamping block II, a piston and the like; cylindrical base metal with a fine thread is plugged into a workpiece through hole and a blind hole which are drilled in advance in the high-speed rotating and downward moving process, spot welding connection is finally achieved, meanwhile, through the tool mounted on the side face, remaining cylindrical base metal on the surface of the workpiece can be cut, and the integrated titanium alloy spot welding technology can be achieved. The device is simple in structure, convenient to operate, high in efficiency and good in mechanical property of a connecting area.

Description

technical field [0001] The invention relates to a titanium alloy spot welding connection technology, specifically, a cylindrical base material with a fine tooth thread is inserted into a pre-drilled through hole and a blind hole of a workpiece during high-speed rotation and downward movement. In the process, the spot welding connection is finally realized, and at the same time, the excess cylindrical base material on the surface of the workpiece is cut off by the cutter installed on the side, and the integrated titanium alloy spot welding connection process is realized. The method is simple and efficient, and the connection joint obtained has good performance. Background technique [0002] At present, there are more and more spot welding connections of titanium alloys, but they are mainly realized by the traditional fusion welding method, which has low efficiency and unstable joint performance, which is not conducive to the wide application of titanium alloy connections. Ba...
