Description

Technical Field

[0001] This utility model relates to the field of copper diffusion welding machine technology, and in particular to a servo electric cylinder pressurization mechanism for a copper diffusion welding machine. Background Technology

[0002] Diffusion welding is a process that brings the surfaces of two workpieces into close contact under specific temperature and pressure conditions. In the high-temperature environment, the atoms on the workpiece surfaces gain sufficient energy, thus becoming highly reactive. These atoms overcome the surface energy barrier and diffuse from one workpiece surface to the other. A copper diffusion welding machine is a device that utilizes diffusion welding technology for welding processes.

[0003] For example, Chinese patent CN213196081U discloses a pressurizing device for diffusion welding equipment and diffusion welding equipment. The pressurizing device includes a pressure rod and a pressure head. The pressure head includes a cooling layer, a heat insulation layer and a pressure-resistant layer connected from top to bottom. The cooling layer is connected to the lower end of the pressure rod. The pressure rod is provided with an inlet pipe and an outlet pipe. The cooling layer is provided with a water-cooled flow channel. One end of the inlet pipe is connected to the inlet of the water-cooled flow channel, and one end of the outlet pipe is connected to the outlet of the water-cooled flow channel. The other ends of the inlet pipe and the outlet pipe are respectively connected to a circulating water cooler. The pressure-resistant layer is provided with multiple mounting holes, and each mounting hole is provided with a heater. The diffusion welding equipment includes a frame, a hydraulic cylinder, a vacuum chamber, a pressure base and the pressurizing device described above.

[0004] Although the aforementioned patent solves the problem of difficulty in cooling the pressure head through a cooling circulation system, the mechanical wear and uneven pressure that occur during long-term use of the pressure head will cause wear and deformation, resulting in changes in the levelness of the pressure head. These changes are not easily detected in time, which can easily lead to uneven welding pressure, loose bonding of welded parts, and affect the welding effect. Utility Model Content

[0005] The purpose of this invention is to solve the problem that mechanical wear and uneven pressure of the pressure head during long-term use in the existing technology can cause wear and deformation of the pressure head, resulting in changes in the levelness of the pressure head. These changes are not easily detected in time, which can easily lead to uneven welding pressure, poor adhesion of welded parts, and affect the welding effect. Therefore, a servo electric cylinder pressure mechanism for copper diffusion welding machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a servo electric cylinder pressurizing mechanism for a copper diffusion welding machine, comprising a fixed plate, a servo electric cylinder body fixedly connected to one side of the fixed plate, a detection component provided at the bottom of the servo electric cylinder body, the detection component comprising a detection container, a position sensor and a tilt sensor, a position sensor fixedly connected to one side of the detection container, a buffer pad fixedly connected to one side of the inner wall of the detection container, a ball bearing installed inside the detection container, a limit frame engaged on one side of the detection container, a mounting frame slidably connected to one side of the limit frame, a pin installed between the limit frame and the mounting frame, and the top of the mounting frame engaged with the detection container, a pressure head body connected to the mounting frame by bolts, and a tilt sensor connected to one side of the pressure head body by bolts.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: A servo electric cylinder pressurizing mechanism for a copper diffusion welding machine includes a fixed plate 2. A servo electric cylinder body 1 is fixedly connected to one side of the fixed plate 2. A detection component is provided at the bottom of the servo electric cylinder body 1. The detection component includes a detection container 6, a position sensor 7, and a tilt sensor 15. One side of the position sensor 7 is fixedly connected to the detection container 6. A buffer pad 11 is fixedly connected to one side of the inner wall of the detection container 6. A ball bearing 10 is installed inside the detection container 6. A limit frame 12 is engaged with one side of the detection container 6. A mounting frame 13 is slidably connected to one side of the limit frame 12. A pin is installed between the limit frame 12 and the mounting frame 13. The top of the mounting frame 13 is engaged with the detection container 6. A pressure head body 14 is bolted to the mounting frame 13. One side of the pressure head body 14 is bolted to the tilt sensor 15. The position sensor 7 and the tilt sensor 15 are electrically connected to a control panel 4. An alarm 5 is fixedly connected to one side of the control panel 4. One side of the control panel 4 is fixedly connected to the fixed plate 2. A frame 3 is fixedly connected to one side of the fixed plate 2.

[0024] The frame 3 provides support for one side of the fixed plate 2, and the fixed plate 2 provides support and reinforcement for one side of the control panel 4. The tilt sensor 15 can detect the tilt angle of the pressure head body 14. The limit frame 12 and the mounting frame 13 can improve the stability of the connection between the testing container 6 and the mounting frame 13. The mounting frame 13 can assist in the installation and use of the testing container 6 on one side of the pressure head body 14. The buffer pad 11 can reduce the collision of the ball bearing 10 with the inner wall of the testing container 6 when it rolls inside the testing container 6. The position sensor 7 can detect the displacement of the ball bearing 10 inside the testing container 6, thereby determining whether the pressure head body 14 is tilted. The control panel 4 can receive the detection results of the position sensor 7 and the tilt sensor 15 for comprehensive judgment, which can reduce the error in the judgment of the ball bearing 10. When the tilt of the pressure head body 14 is detected, the alarm 5 will sound an alarm in time, which will facilitate the staff to check and repair in time.

[0025] Example 2: Figures 1-4As shown, a guide rod 19 is fixedly connected to the top of the pressure head body 14. A connecting plate 8 is inserted into the top of the guide rod 19. A connecting shaft 9 is fixedly connected to the top of the connecting plate 8. The connecting shaft 9 is slidably connected to the frame 3. The top of the connecting shaft 9 is fixedly connected to one end of the servo electric cylinder body 1. A plug rod 18 is inserted inside the guide rod 19. The plug rod 18 is inserted through the connecting plate 8. A limit pin 21 is inserted between the plug rod 18 and the guide rod 19. A limit strip 16 is fixedly connected to one end of the plug rod 18. The bottom of the limit strip 16 is engaged with the connecting plate 8. A rack 17 is inserted into one side of the limit strip 16. The rack 17 is slidably connected to the connecting plate 8. A gear 20 meshes with one side of the rack 17. The bottom of the gear 20 is rotatably connected to the connecting plate 8.

[0026] The guide rod 19 guides the installation of the pressure head body 14 and assists in the connection between the pressure head body 14 and the connecting plate 8. The insertion of the plug rod 18 into the guide rod 19 improves the tightness of the connection between the pressure head body 14 and the connecting plate 8. The engagement of the limiting strip 16 with the connecting plate 8 enables the connection between the limiting strip 16 and the connecting plate 8. The connecting plate 8 supports the bottom of the gear 20. The rotation of the gear 20 adjusts the position of the rack 17, thereby controlling the connection or separation between the rack 17 and the limiting strip 16. When the rack 17 is connected to the limiting strip 16, the stability of the limiting strip 16 installed on the top of the connecting plate 8 is improved.

[0027] The operating method and working principle of this device are as follows: First, the servo electric cylinder body 1 drives the connecting shaft 9 and the connecting plate 8 to move downwards. During the downward movement, the position sensor 7 detects the displacement of the ball bearing 10 at the center position of the detection container 6. When the position sensor 7 is not moving in the horizontal direction, the pressure head body 14 is in a horizontal state. When the pressure head body 14 is tilted, the ball bearing 10 will roll to the lower side. By detecting the position of the ball bearing 10 through the position sensor 7, the tilt of the pressure head body 14 can be determined. At the same time, the tilt sensor 15 is used to assist in detecting the tilt angle of the pressure head body 14. The collected data is sent to the PLC controller on the control panel 4. After processing, it is determined that the horizontality of the pressure head body 14 has changed. At this time, alarm 5 sounds, and the operator interrupts the circuit of the copper diffusion welding machine to stop the machine. The operator moves the limit pin 21 so that the end of the limit pin 21 separates from the plug rod 18, the guide rod 19 and the pressure head body 14 in sequence. Then, the operator rotates two gears 20 on the top of the connecting plate 8. Through the meshing of the gears 20 and the rack 17, the rack 17 is driven to move, so that one end of the rack 17 separates from the limit strip 16. Then, the limit strip 16 is moved up so that the plug rod 18 at the bottom of the limit strip 16 separates from the guide rod 19. The pressure head body 14 is moved down so that the guide rod 19 separates from the connecting plate 8. The pressure head body 14 can be disassembled and replaced. After replacement, the mounting bracket 13 and the tilt sensor 15 are installed on the new pressure head body 14.
