[0036] The present invention is further described with reference to the following examples.

[0037] Depend on Figures 1 to 8 It can be seen that the copper male quick positioning fixture described in this embodiment includes a base 11 and a column 12; two sets of clamp mechanisms are movably provided on the base 11; each set of clamp mechanisms includes two positioning clamps 2 arranged opposite to each other; a first driving mechanism and a second driving mechanism are provided on the base 11; the first driving mechanism and the second driving mechanism are respectively used to drive the two sets of clamp mechanisms to move;

[0038] The column 12 is movably provided with a fixing fixture 3; the column 12 is provided with a third driving mechanism for driving the fixing fixture 3 to rise and fall; the fixing fixture 3 is provided above the positioning fixture 2; the fixing fixture 3 is provided with an alignment portion.

[0039] Specifically, the copper male quick positioning fixture described in this embodiment, when the copper male 8 needs to be positioned, first the copper male 8 is placed on the base 11, and then the two sets of clamp mechanisms are moved respectively by the first driving mechanism and the second driving mechanism, so that the copper male 8 is clamped on the four positioning clamps 2 of the two sets of clamp mechanisms, and the copper male 8 is positioned;

[0040] In addition, the fixing fixture 3 is used to install the bar 9. The bar 9 is provided with an alignment portion 91 that cooperates with the alignment portion. The alignment portion 91 cooperates with the alignment portion so that the position of the bar 9 can be fixed. When the copper male 8 is clamped on the four positioning fixtures 2 of the two sets of fixture mechanisms, the fixing fixture 3 and the bar 9 are driven down by the third driving mechanism until the bar 9 contacts the surface of the copper male 8. The bar 9 and the copper male 8 can be bonded by glue. Since the direction of the copper male 8 and the direction of the bar 9 are fixed on the positioning fixture 2 and the fixing fixture 3 respectively Therefore, the relative positions of the copper male 8 and the rod 9 are also fixed, so that after the copper male 8 is connected to the rod 9, it can be directly installed on the spark machine without adjusting the direction and inclination of the copper male 8; specifically, a positioning portion that cooperates with the alignment portion 91 is provided on the spark machine, and the positioning portion is the same as the first positioning surface 33 and the second positioning surface 34, so that when the rod 9 is installed on the positioning portion of the spark machine, the position, direction and inclination of the rod 9 and the copper male 8 are fixed, and there is no need to calibrate and center the copper male 8 again, which greatly improves work efficiency.

[0041] In the copper male quick positioning fixture described in this embodiment, the first driving mechanism includes a first rotating rod 4, a first nut 41, a second nut 42 and a first driving member 43;

[0042] One end of the first rotating rod 4 is provided with a first thread 44; the other end of the first rotating rod 4 is provided with a second thread 45; the thread rotation direction of the first thread 44 is opposite to the thread rotation direction of the second thread 45;

[0044] The first driving member 43 is connected to the first rotating rod 4 .

[0045] Specifically, when it is necessary to move the positioning fixture 2, the first driving member 43 is rotated to rotate the first rotating rod 4. Since the thread rotation direction of the first thread 44 is opposite to the thread rotation direction of the second thread 45, when the first rotating rod 4 is rotated, the two positioning fixtures 2 of a set of clamping mechanisms can approach and move away from each other, thereby achieving the positioning and clamping of the copper male 8.

[0049] The second driving member 53 is connected to the second rotating rod 5 .

[0050] Specifically, when it is necessary to move another group of positioning fixtures 2, the second driving member 53 is rotated to rotate the second rotating rod 5. Since the thread rotation direction of the third thread is opposite to the thread rotation direction of the fourth thread, when the second rotating rod 5 is rotated, the two positioning fixtures 2 of the other group of clamping mechanisms can approach and move away from each other, thereby achieving the positioning and clamping of the copper male 8.

[0057] The third driving member 71 is an electric cylinder.

[0058] Specifically, when the fixing fixture 3 needs to be moved, the electric cylinder is started, and the electric cylinder can drive the fixing fixture 3 and the support plate 72 to move up and down along the slide rail 73 and the slider 74.

[0059] In this embodiment, a copper male quick positioning fixture is provided, wherein the fixing fixture 3 is provided with a mounting groove 31; the fixing fixture 3 is provided with a screw hole 32 communicating with the mounting groove 31;

[0060] The alignment portion includes a first positioning surface 33 and a second positioning surface 34 disposed in the mounting groove 31 ; the first positioning surface 33 and the second positioning surface 34 are disposed perpendicularly.
