Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and Advantageous Effects thereof become apparent from, below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.It should be appreciated that the detailed description of the invention described in this specification is only used to explain this utility model, it is not intended to limit this utility model.
This utility model three-shaft linkage automatic welding device includes automatic part and the mash welder host machine part of welding quality automated watch-keeping facility of three-shaft linkage spot welding head, illustrates two parts separately below:
One, the automatic part of three-shaft linkage spot welding head
Refer to shown in Fig. 1, this utility model three-shaft linkage spot welding head automatic welding device includes:
Three-shaft linkage spot welding head 101, it includes base plate 105, is anchored on base plate 105 side and is provided with the Y-axis slide unit 107 of Y-axis slide block 107A, is arranged on Y-axis slide block 107A and is provided with the X-axis slide unit 106 of X-axis slide block 106A, be installed on X-axis slide block 106A and be provided with the spot welding head 104 of the welding head holder 109 that can install parallel electrode welding head, and be arranged on spot welding head 104 and be provided with the Z axis slide unit 108 of Z axis slide block 108A, wherein, Z axis slide block 108A is flexibly connected with spot welding head 101；
