Description

Technical Field

[0001] The utility model relates to the technical field of diffusion welding equipment, in particular to a pressure head structure for diffusion welding equipment. Background Art

[0002] Diffusion welding is a solid-state welding method that pressurizes the workpiece at high temperature without causing visible deformation or relative movement. Diffusion welding is particularly suitable for joining dissimilar metal materials, heat-resistant alloys and ceramics, intermetallic compounds, composite materials and other new materials. Especially for materials that are difficult to weld by fusion welding, diffusion welding has obvious advantages and is increasingly attracting people's attention. Generally, the pressure head structure of the diffusion welding equipment is used to press the material.

[0003] The patent specification with the announcement number CN206169483U discloses a pressure head structure for diffusion welding equipment, including a loading plate and a loading rod, wherein the loading plate is mounted at one end of the loading rod, a restraining cavity is arranged on the loading plate, a ball head is arranged at one end of the loading rod close to the loading plate, the ball head is placed in the restraining cavity, the shape of the restraining cavity is consistent with that of the ball head, and the ball head can rotate in the restraining cavity. The pressure head structure for diffusion welding equipment provided by the present application improves the service life of the telescopic mechanism.

[0004] However, in the implementation of relevant technologies, it was found that the pressure head structure for a diffusion welding device designed as above has the following problems: in the prior art, the loading plate is adjusted to fit the material by rotating the ball head, but the loading plate cannot be reset after each press. If the last tilt angle is too skewed, the corners of the loading plate may come into contact with the material during the subsequent pressing process, thereby causing bumps and collisions, which have a certain impact on the material. In view of this, a pressure head structure for a diffusion welding device is provided to overcome the above defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a pressure head structure for diffusion welding equipment.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pressure head structure for diffusion welding equipment, comprising a lower pressure rod, the bottom end of which is connected to a ball head, and the outer sleeve of the ball head is provided with a lower pressure plate, the outer part of the lower pressure rod is slidably connected to a fixed plate, and a reset mechanism is provided below the fixed plate;

[0007] The reset mechanism includes a first damping spring, which is fixed to the bottom end of the fixed plate, and one end of the first damping spring is connected to a limiting plate, an insertion rod is fixed to the top of the lower pressure plate, and a liquid injection groove is provided on one side of the outer wall of the lower pressure plate, an insertion hole is provided on one side of the first damping spring at the bottom end of the fixed plate, and a pressure sensor is embedded in the inner wall of the insertion hole. When the lower pressure rod drives the lower pressure plate to reset, the limiting plate is elastically pushed by the first damping spring to limit the lower pressure plate, and a force is applied to compress the first damping spring, so that the angle of the lower pressure plate can be adjusted through the ball head, thereby ensuring that the lower pressure plate is corrected to avoid tilting and affecting the next processing.

[0008] As a further description of the above technical solution: the limiting plate forms an elastic structure with the fixed plate through the first damping spring, and a sliding structure is formed between the fixed plate and the lower pressure rod. The lower pressure rod is limited by the fixed plate to keep the sliding process of the lower pressure rod stable and avoid deviation. At the same time, the fixed plate is fixed to the diffusion welding equipment frame.

[0009] As a further description of the above technical solution: a bonding plate is fixed to the top of the fixed plate outside the lower pressure rod, and a slider is fixed axially where the lower pressure rod penetrates into the bonding plate. The axial slider of the lower pressure rod slides along the bonding plate, further improving the stability of the movement of the lower pressure rod to avoid excessive shaking and affect the lower pressure plate.

[0010] As a further description of the above technical solution: a connecting plate is fixed to one end of the slider that passes through the bonding plate, and a second damping spring is installed between the connecting plate and the fixed plate. When the slider slides, it drives the connecting plate and compresses the second damping spring to have a certain shock absorption effect at the top of the fixed plate.

[0011] As a further description of the above technical solution: a sliding structure is formed between the slider and the bonding plate, and the slider is fixedly connected to the connecting plate. The connecting plate slides along the bonding plate through the slider to maintain the stability of the sliding process and avoid shaking when the second damping spring is compressed.

[0012] As a further description of the above technical solution: an adjustment mechanism is arranged above the fixed plate, and the adjustment mechanism includes a motor, and the motor is embedded on one side of the second damping spring above the fixed plate, and the power output end of the motor is connected to a driving rod, and a rotating plate is fixed to the bottom end of the driving rod, and a scraper is fixed to the outer wall of the rotating plate facing the lower pressure plate, and the driving rod is driven by the motor, so that the rotating plate drives the scraper to slide against the bottom end of the lower pressure plate for correction.

[0013] As a further description of the above technical solution: the scraper is tightly fitted with the lower pressure plate, and a sliding structure is formed between the scraper and the lower pressure plate. When the scraper slides in contact with the lower pressure plate, impurities adsorbed on the bottom of the lower pressure plate are scraped off to avoid affecting the next processing and affecting the material.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs a pressure head structure for diffusion welding equipment, which pushes a limit plate through the elasticity of a first damping spring to limit the reset lower pressure plate, so that the lower pressure plate can be corrected by rotating the ball head to avoid tilting and affecting the next processing. After resetting, the insertion rod penetrates the insertion hole and touches the pressure sensor. When the pressure sensor receives a pressure signal and transmits it to the background control of the equipment, it proves that the lower pressure plate has been reset and is in a corrected state, and the next work can be carried out.

[0016] The utility model designs a pressure head structure for diffusion welding equipment. When the lower pressure rod drives the slider to slide, the connecting plate elastically presses the second damping spring to achieve a certain shock absorption. After the lower pressure plate is pressed down, it is reset to the height of the rotating plate for the first time. The driving rod is driven by the motor to drive the scraper to scrape the bottom end of the lower pressure plate, thereby achieving preliminary correction. At the same time, the scraper scrapes off the dust and impurities adsorbed on the bottom end of the lower pressure plate to avoid residual impurities affecting the next processing. The two sets of motors rotate at opposite angles to avoid the same rotation, which results in the scraper being unable to press the lower pressure plate and causing it to tilt. After the background control sets the motor to operate for a certain period of time, the lower pressure rod continues to reset for the next step of correction. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The reset mechanism 5 includes a first damping spring 502, which is fixed at the bottom end of the fixed plate 4, one end of the first damping spring 502 is connected to the limiting plate 501, an insertion rod 503 is fixed at the top of the lower pressure plate 3, a liquid injection groove 506 is provided on one side of the outer wall of the lower pressure plate 3, an insertion hole 504 is provided on one side of the first damping spring 502 at the bottom end of the fixed plate 4, and a pressure sensor 505 is embedded on the inner wall of the insertion hole 504. When the lower pressure rod 1 drives the lower pressure plate 3 to reset, the limiting plate 501 is elastically pushed by the first damping spring 502 to limit the lower pressure plate 3, and a force is applied to compress the first damping spring 502, so that the lower pressure plate 3 can adjust the angle through the ball head 2, thereby ensuring that the lower pressure plate 3 is corrected to avoid tilting and affecting the next processing.

[0026] As a further implementation scheme of the above technical scheme: the limiting plate 501 forms an elastic structure with the fixed plate 4 through the first damping spring 502, and a sliding structure is formed between the fixed plate 4 and the lower pressure rod 1. The lower pressure rod 1 is limited by the fixed plate 4 to keep the sliding process of the lower pressure rod 1 stable and avoid deviation. At the same time, the fixed plate 4 is fixed to the frame of the diffusion welding equipment.

[0027] As a further implementation scheme of the above technical scheme: the top end of the fixed plate 4 is located outside the lower pressure rod 1 and is fixed with a bonding plate 6, the lower pressure rod 1 penetrates into the bonding plate 6 and is axially fixed with a slider 7, the axial slider 7 of the lower pressure rod 1 slides along the bonding plate 6, further improving the stability of the movement of the lower pressure rod 1 to avoid excessive shaking and affect the lower pressure plate 3.

[0028] During specific implementation, the lower pressure rod 1 slides along the fitting plate 6 through the slider 7 and slides in the fixed plate 4, thereby improving the sliding stability of the lower pressure rod 1. After the lower pressure rod 1 pushes the lower pressure plate 3, it resets. The first damping spring 502 elastically pushes the limit plate 501, and the ball head 2 limits and corrects the lower pressure plate 3 to avoid tilting. At the same time, the insertion rod 503 fixed on the lower pressure plate 3 penetrates into the fixed plate 4 through the insertion hole 504 and touches the pressure sensor 505, thereby reminding the background of the equipment that the lower pressure plate 3 is in the correct position for the next work, and the lubricating liquid is easily injected through the liquid injection groove 506 to keep the ball head 2 and the lower pressure plate 3 lubricated.

[0031] As a further implementation scheme of the above technical scheme: an adjustment mechanism 10 is arranged above the fixed plate 4, and the adjustment mechanism 10 includes a motor 1001. The motor 1001 is embedded on one side of the second damping spring 9 above the fixed plate 4, and the power output end of the motor 1001 is connected to a driving rod 1002. A rotating plate 1003 is fixed to the bottom end of the driving rod 1002. A scraper 1004 is fixed to the outer wall of the rotating plate 1003 facing the lower pressure plate 3. The driving rod 1002 is driven by the motor 1001, so that the rotating plate 1003 drives the scraper 1004 to slide against the bottom end of the lower pressure plate 3 for correction.

[0032] As a further implementation scheme of the above technical scheme: the scraper 1004 is tightly fitted with the lower pressure plate 3, and a sliding structure is formed between the scraper 1004 and the lower pressure plate 3. When the scraper 1004 slides against the lower pressure plate 3, impurities adsorbed on the bottom of the lower pressure plate 3 are scraped off to avoid affecting the next processing and affecting the material.

[0033] During specific implementation, the second damping spring 9 provides elastic support to the slider 7 of the connecting plate 8, so that the lower pressure rod 1 has a certain shock absorption when sliding, and the motor 1001 drives the driving rod 1002, so that the rotating plate 1003 drives the scraper 1004 to slide along the bottom end of the lower pressure plate 3, so that the lower pressure plate 3 remains in the correct state and impurities adsorbed on the surface are scraped off.
