Description

Technical Field

[0001] This invention belongs to the field of welding technology, and in particular relates to a novel welding device and method for titanium magnetic shells. Background Technology

[0002] Products welded with titanium shells for magnets require high airtightness. Therefore, ensuring the integrity of the weld seam is crucial. This necessitates precise pre-welding positioning and prevents relative movement between the product and the laser head during welding. Currently, the conventional welding process involves welding several points between the two workpieces for positioning before placing them in a welding fixture. While this method provides relatively accurate welding, it also presents several problems. Firstly, because the magnets are placed into the fixture using a hand-cranked clamping device, the clamping force is uncontrollable, easily causing deformation of the titanium shell and resulting in mispositioning. Secondly, repeated welding of the positioning points can lead to burn-through, resulting in airtightness issues and product scrap. Therefore, a novel titanium shell welding solution is needed to address the difficulties in clamping and inaccurate positioning during magnet welding, thereby improving welding efficiency and product yield. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art by providing a novel magnetic titanium shell welding device and method, solving the problems of difficult clamping and inaccurate positioning during magnetic welding, and improving welding efficiency and product qualification rate.

[0004] The objective of this invention can be achieved through the following technical solutions:

The support frame ball bearing sleeve and the support frame linear bearing sleeve are connected by the support frame connecting rod. The two ends of the rolling connecting rod are respectively installed inside the second bearing sleeve and the first bearing sleeve for placing multiple magnet titanium shells to be welded. The multiple magnet titanium shells to be welded are pressed axially by the pressure rod and the spring, and elastically pressed radially by the pressure plate. The spring is sleeved on one end of the sliding pressure rod. The sliding pressure rod is located inside the linear bearing. The pressure plate is hollowed out to expose the weld seam of the magnet titanium shells to be welded. The two ends of the pressure plate are respectively fixed on the second bearing sleeve and the first bearing sleeve.

[0007] Furthermore, one end of the bearing fixing shaft is inserted and fixed to the connecting shaft, and the other end is screwed and fixed to the pressure rod.

[0008] Furthermore, the connecting shaft and the bearing fixing shaft are fastened together with M2.5 metric screws.

[0009] Furthermore, positioning pins are fixed on the ball bearing sleeve of the support frame and the linear bearing sleeve of the support frame.

[0010] Furthermore, the support frame connecting rod is connected to the support frame ball bearing sleeve and the support frame linear bearing sleeve by M3 screws.

[0013] Furthermore, the two ends of the pressure plate are fixed to the second bearing sleeve and the first bearing sleeve respectively by spring screws.

[0014] Furthermore, an actuating cam is mounted on the end of the sliding lever away from the spring.

[0015] The present invention also provides a novel method for welding a titanium shell using a novel titanium shell welding device described above, comprising the following steps:

[0016] S1. Place multiple titanium shells of magnets to be welded into the rolling connecting rod and fix them by pressure plates and springs;

[0017] S2. Mount the new magnet titanium shell welding device onto the welding equipment, retrieve the welding program, and drive the magnet titanium shell to be welded to rotate by the connecting shaft. Run one revolution empty to check the clamping status. If the clamping status is correct, start laser welding.

[0018] S3. Remove the completed welded titanium magnet shell and load it into the next batch of titanium magnet shells to be welded.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention proposes a novel magnetic titanium shell welding device, comprising a rotating mechanism, a fixed support mechanism, and a spring-loaded mechanism. The rotating mechanism drives the magnetic titanium shell to be welded to rotate and includes a connecting shaft, a bearing fixing shaft, a pressure rod, a first ball bearing, a second ball bearing, a spring, a linear bearing, a sliding pressure rod, and a rolling connecting rod. The fixed support mechanism supports the rotating mechanism and includes a support frame ball bearing sleeve, a second bearing sleeve, a first bearing sleeve, a support frame linear bearing sleeve, and a support frame connecting rod. The spring-loaded mechanism fixes the magnetic titanium shell to be welded and includes a pressure plate and a spring. Specifically, one end of the bearing fixing shaft is fixed to the connecting shaft, and the other end is fixed to the pressure rod. The first ball bearing is sleeved on the end of the bearing fixing shaft away from the connecting shaft, and the second ball bearing is mounted on the first shaft. Within the bearing sleeve and the second bearing sleeve, the first bearing sleeve and the support frame ball bearing sleeve are sequentially fitted onto the first ball bearing, which is mounted on the bearing fixed shaft. The second bearing sleeve and the support frame linear bearing sleeve are sequentially fitted onto the linear bearing. The support frame ball bearing sleeve and the support frame linear bearing sleeve are connected by a support frame connecting rod. The two ends of the rolling connecting rod are respectively installed within the second bearing sleeve and the first bearing sleeve, for placing multiple titanium shells of magnets to be welded. These multiple titanium shells are axially compressed by a pressure rod and a spring, and radially compressed by a pressure plate. The spring is fitted onto one end of a sliding pressure rod, which is located within the linear bearing. The pressure plate is perforated to expose the weld seam of the titanium shells to be welded. The two ends of the pressure plate are fixed to the second bearing sleeve and the first bearing sleeve, respectively. This device eliminates the need for pre-marking the titanium shells to be welded and prevents deformation due to overpressure. It allows for the simultaneous welding of multiple products, solving the problems of clamping difficulties and inaccurate positioning during magnet welding, thus improving welding efficiency and product qualification rate.

[0021] 2. The present invention has multiple clearance positions evenly arranged on the rolling connecting rod, which can prevent weld scars from affecting the rotation of the titanium magnet shell during the welding process and affecting the welding effect; the present invention has positioning pins fixed on the ball bearing sleeve and linear bearing sleeve of the support frame, which facilitates the positioning and installation of the support frame connecting rod.

[0022] 3. In this invention, a lever cam is installed at the end of the sliding pressure rod away from the spring. By raising and lowering the lever cam, the state switching and control of the sliding pressure rod can be realized. The lever cam mainly transmits power through rotation or sliding. The movement process is relatively smooth and is not prone to impact and vibration, which can improve the stability and reliability of the device.

[0023] 4. This invention also proposes a novel method for welding titanium shells of magnets. Through simple operation, multiple workpieces can be welded at once, which greatly improves the welding efficiency. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0030] Example 1

[0031] This embodiment provides a novel magnetic titanium shell welding device, such as... Figure 1 , Figure 2 and Figure 3As shown, the mechanism includes a rotating mechanism, a fixed support mechanism, and a spring-loaded mechanism. The rotating mechanism, used to drive the titanium shell of the magnet to be welded to rotate, includes a connecting shaft 1, a bearing fixing shaft 16, a pressure rod 5, a first ball bearing 3, a second ball bearing 18, a linear bearing 10, a sliding pressure rod 12, and a rolling connecting rod 19. The fixed support mechanism, used to support and fix the rotating mechanism, includes a support frame ball bearing sleeve 2, a second bearing sleeve 8, a first bearing sleeve 4, a support frame linear bearing sleeve 9, and a support frame connecting rod 15. The spring-loaded mechanism, used to fix the titanium shell of the magnet to be welded, includes a pressure plate 6 and a spring 7.

[0032] Specifically, one end of the bearing fixing shaft 16 is inserted and fixed to the connecting shaft 1, and the other end is screwed and fixed to the pressure rod 5 and tightened with an M2.5 nut screw 17. The first ball bearing 3 is sleeved on the end of the bearing fixing shaft 16 away from the connecting shaft 1. 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 fixing shaft 16. 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 with an M3 screw 14. The support frame ball bearing sleeve 2 and the support frame linear bearing sleeve 9 are fixed with positioning pins 13 to facilitate the positioning and installation of the support frame connecting rod 15.

[0033] The two ends of the rolling connecting rod 19 are respectively installed in the second bearing sleeve 8 and the first bearing sleeve 4, for accommodating multiple titanium shells of magnets to be welded. Figure 4 As shown, multiple clearance positions are evenly arranged on the rolling connecting rod 19 to prevent weld spatter from affecting the rotation of the titanium magnetic shell during the welding process and thus the welding effect. Multiple titanium magnetic shells to be welded are axially pressed by the pressure rod 5 and spring 7, and radially pressed by the pressure plate 6 to prevent overpressure and deformation of the shells. The spring 7 is fitted onto one end of the sliding pressure rod 12, which is located inside the linear bearing 10. The pressure plate 6 is perforated to expose the weld seam of the titanium magnetic shells to be welded. Both ends of the pressure plate 6 are fixed to the second bearing sleeve 8 and the first bearing sleeve 4 respectively by spring screws 20. A lever cam 11 is installed at the end of the sliding pressure rod 12 away from the spring 7. The lever cam can be raised and lowered to achieve state switching and control of the sliding pressure rod. The lever cam mainly transmits power through rotation or sliding, resulting in relatively smooth movement and minimizing impact and vibration, thus improving the stability and reliability of the device.

[0034] The specific assembly method of the above-mentioned device is as follows:

[0035] Step 1: Assemble the ball bearing assembly. 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. Slide 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. Fix the locating pin 13 onto 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).

[0036] Step 2: Assemble the linear bearing assembly. First, fit the second bearing sleeve 8 into the linear bearing 10 and tighten it with screws. Then, fit the bracket linear bearing sleeve 9 into the linear bearing 10 and tighten it with screws. Fit 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.

[0037] Step 3: Install the connecting parts. First, insert the rolling connecting rod 19 into the first bearing sleeve 4 and the second bearing sleeve 8, which contain the second ball bearing 18. Then, connect the support frame connecting rod 15 to the support frame ball bearing sleeve 2 and the support frame linear bearing sleeve 9 using M3 screws 14. Finally, place the workpiece to be welded into the rolling connecting rod 19 and fix it with the pressure plate 6. The entire welding device is now assembled.

[0038] The above-mentioned device does not require pre-marking and positioning of the titanium shell of the magnet to be welded, and will not cause deformation of the titanium shell due to overpressure. It can weld multiple products at one time, solve the problems of difficult clamping and inaccurate positioning when welding magnets, and improve welding efficiency and product qualification rate.

[0039] Example 2

[0040] This embodiment provides a novel magnetic titanium shell welding method based on the novel magnetic titanium shell welding device as described in Embodiment 1, including the following steps:

[0041] S1. Move the lever cam 11 to lift the sliding pressure rod 12, placing multiple titanium shells to be welded into the rolling connecting rod 19, and then remove the lever cam 11. Since the titanium shells contain magnets, 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 titanium shells to be welded will be clamped onto the new type of titanium shell welding device.

[0042] S2. The new type of magnetic titanium shell welding device is clamped onto the welding equipment using a three-jaw chuck. The welding program is retrieved, and the connecting shaft 1 drives the magnetic titanium shell to be welded to rotate. A full rotation is performed to check the clamping status. If the clamping status is correct, laser welding is initiated. During rotation, due to the presence of 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 together. Due to gravity, the above mechanisms will always remain vertically downward and will not obstruct the welding process.

[0043] S3. Remove the completed welded titanium magnet shell and load it into the next batch of titanium magnet shells to be welded.

[0044] The above method is simple to operate, can solve the problem of difficult product clamping and positioning, and can complete the welding of multiple workpieces at one time, greatly improving welding efficiency.

[0045] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
