[0028] Embodiment:

[0029] The present embodiment provides a new type of magnet titanium shell welding device, such as Figure 1 , Figure 2 and Figure 3As shown, it comprises a rotating mechanism, a fixed support mechanism and a spring pressing mechanism.

The second ball bearing 18 is installed in the first bearing sleeve 4 and the second bearing sleeve 8, the first bearing sleeve 4 and the support frame ball bearing sleeve 2 are sequentially sleeved on the first ball bearing 3, the first ball bearing 3 is installed on the bearing fixed shaft 16, and the second bearing sleeve 8 and the support frame linear bearing sleeve 9 are sequentially sleeved on the linear bearing 10. The support frame connecting rod 15 connects the support frame ball bearing sleeve 2 and the support frame linear bearing sleeve 9 through an M3 screw 14, and the support frame ball bearing sleeve 2 and the support frame linear bearing sleeve 9 are fixed with positioning pins 13, which facilitates the positioning and installation of the support frame connecting rod 15.

[0031] The two ends of the rolling connecting rod 19 are respectively installed in the second bearing sleeve 8 and the first bearing sleeve 4, and are used to place a plurality of magnet titanium shells to be welded. Figure 4 As shown, a plurality of empty positions are uniformly arranged on the rolling connecting rod 19, which can avoid the influence of welding scars on the rotation of the magnet titanium shell during the welding process and affect the welding effect. A plurality of magnet titanium shells to be welded are pressed in the axial direction by the pressing rod 5 and the spring 7, and are elastically pressed in the radial direction by the pressing plate 6, which can avoid over-pressing and deformation of the titanium shell. The spring 7 is sleeved on one end of the sliding pressing rod 12, the sliding pressing rod 12 is located in the linear bearing 10, the pressing plate 6 is hollow to expose the weld of the magnet titanium shell to be welded, and the two ends of the pressing plate 6 are fixed on the second bearing sleeve 8 and the first bearing sleeve 4 by spring screws 20. A pulling cam 11 is installed at the end of the sliding pressing rod 12 away from the spring 7, and the state conversion and control of the sliding pressing rod can be realized by pulling up and pressing down the pulling cam. The pulling cam mainly transmits power by rotation or sliding, the movement process is relatively stable, and impact and vibration are not easy to occur, which can improve the stability and reliability of the device.

[0032] The assembly method of the above device is as follows:

[0033] Step 1: Assemble the ball bearings. First, install the second ball bearing 18 into the first bearing sleeve 4 and the second bearing sleeve 8. Install the first ball bearing 3 onto the bearing fixing shaft 16. Insert the bracket ball bearing sleeve 2 and the first bearing sleeve 4 with the second ball bearing 18 into the first ball bearing 3 and secure them with screws. Secure the positioning pin 13 to the bracket ball bearing sleeve 2 and the bracket linear bearing sleeve 9. Then screw the pressure rod 5 into the bearing fixing shaft 16, insert the bearing fixing shaft 16 into the connecting shaft 1 and tighten it with screws (17).

[0034] Step 2: Assemble the linear bearing. First, insert the second bearing sleeve 8 into the linear bearing 10 and tighten it with screws. Then insert the bracket linear bearing sleeve 9 into the linear bearing 10 and tighten it with screws. Insert the spring 7 into the sliding pressure rod 12, and insert the sliding pressure rod 12 with the spring 7 into the linear bearing 10.

[0035] Step 3: Install the connecting parts. First, insert the rolling link 19 into the first bearing sleeve 4 and the second bearing sleeve 8 with the second ball bearing 18. Then, use M3 screws 14 to connect the support frame connecting rod 15 to the support frame ball bearing sleeve 2 and the support frame linear bearing sleeve 9. Finally, place the workpiece to be welded into the rolling link 19 and secure it with the pressure plate 6. The entire welding device is assembled.

[0036] The above device does not require pre-marking and positioning of the titanium shell of the magnet to be welded, and there will be no deformation of the titanium shell due to overpressure. Multiple products can be welded at one time, solving the problems of difficult clamping and inaccurate positioning during magnet welding, and improving welding efficiency and product qualification rate.

[0037] The usage of the above device is as follows:

[0038] S1. Pull the cam 11, pull up the sliding pressure rod 12, place multiple magnet titanium shells to be welded into the rolling connecting rod 19, and then remove the cam 11. Because the magnet titanium shells contain magnets, the multiple titanium shells to be welded will be magnetically attracted together. Due to the presence of the spring 7 and the pressure plate 6, the magnet titanium shells to be welded will be tightened on the new magnet titanium shell welding device.

[0039] S2. Clamp the new magnet titanium shell welding device onto the welding equipment using a three-jaw chuck. Recall the welding program. Connect shaft 1 to rotate the magnet titanium shell to be welded. Perform an idle rotation to check the clamping status. If the clamping status is correct, start laser welding. During rotation, due to the presence of the bearings, the support frame ball bearing sleeve 2, first bearing sleeve 4, pressure plate 6, second bearing sleeve 8, support frame linear bearing sleeve 9, and support frame connecting rod 15 will not rotate with it. Due to the effect of gravity, the above mechanism will always remain vertically downward and will not obstruct the welding.

[0040] S3, the magnet titanium shell of completing welding is taken out, and is loaded into the next batch of magnet titanium shells to be welded.

[0041] The method is simple in operation, can solve the problems of product clamping and positioning, can complete the welding of multiple workpieces at a time, and greatly improves the welding efficiency.

[0042] The above merely describes a specific implementation of the present application, but the scope of protection of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be covered within the scope of protection of the present application. Therefore, the scope of protection of the present application should be subject to the scope of protection of the claims.
