[0033] See also Figure 1-5 The utility model is a vacuum welding device for target material welding process, and the welding device is mainly composed of an electron gun 10, a rotating head 20, a tip 30, a welding chamber, etc. The electron gun 10 is used to emit particles to hit the target material, so that the surface material of the target material melts to achieve the purpose of welding. The three-claw rotating head 20 cooperates with the tip 30 to clamp the target material directly, and then proceed to the next welding process. The rotating head 20 is used to clamp the target material and provide a rotating action, which allows the electron gun 10 to evenly hit the particles on the surface of the target material, thereby better providing a welding action. The tip 30 is used to support the other side of the target material after the rotating head 20 fixes one end of the target material, so that the target material can be directly fixed in the welding chamber. The welding chamber is used to provide a vacuum environment to better realize the target material welding process.

[0034] See also Figure 1-4In one embodiment of the utility model, a rotary head 20 for a target welding process comprises an outer body 21 and an inner body 22, wherein the outer body 21 is fixedly connected to the main body of the equipment for supporting, and an adjustment chamber is provided in the outer body 21; the inner body 22 is arranged in the adjustment chamber, and a three-claw chuck for clamping a workpiece and its related driving structure are respectively arranged on the inner body 22; the inner body 22 and the outer body 21 are connected by a rotating shaft 23, that is, a rotating shaft 23 is fixedly arranged on both sides of the inner body 22, and a corresponding shaft hole is provided on the side wall of the outer body 21. A bearing seat 24 is provided in the shaft hole for playing the role of a slewing support for the rotating shaft 23, so as to ensure smoother rotation of the mechanism. A dust cover 25 can be provided at the outer end of the shaft hole for playing the role of blocking and protecting, and the dust cover 25 is used to prevent external dust from entering the mechanism, thereby affecting the stable operation of the mechanism.

[0035] See also Figure 1-4 In one embodiment of the utility model, the rotating shaft 23 may be provided with a power structure for driving. The power structure may include a rotating motor 26, the rotating motor 26 drives a rotating member 27, the rotating member 27 is fixedly connected to a rotating disk 28 fixedly sleeved on the rotating shaft 23, the power output by the rotating motor 26 drives the rotating member 27 to rotate, and then transmits the power to the rotating disk 28, and finally drives the inner body 22 and the entire mechanism thereon to change and adjust the angle through the rotating shaft 23. Furthermore, an indicating scale may be provided around the rotating shaft 23 on the outer body 21, and after rotating a certain angle, the angle of rotation can be directly read through the indicating scale, and it can be rotated to different angle scales according to the different process parameters of the target material, and the welding process requirements of the special-shaped target material can be met by changing its own rotation angle.

[0036] See also Figure 5In one embodiment of the utility model, the existing device manually rotates the top 30 and rotates the rotating head 20 to hold the target material in place during actual welding. In this process, the target material must be fixed on the head by manpower first, and another person rotates the top 30 to fix the target material. This is inefficient and requires two people to complete the target fixing step. Therefore, a telescopic drive structure is provided on the main body of the device, and the free end of the telescopic drive structure is connected to the top 30. The telescopic drive can be a pneumatic structure. By setting a pneumatic top 30, the movement of the top 30 can be controlled by air pressure, and one person can complete the target fixing step through a pneumatic switch. A cylinder is installed behind the top 30 on the device, and the cylinder can directly drive the extension and retraction of the top 30. A remote control is set up to control the cylinder, so that one person can fix the target material on the head and then use the remote control to directly control the top 30 to hold the target material. Semi-automatic action is achieved at one time, and one person can complete the target clamping process, saving labor and improving work efficiency.
