Description

Technical Field

[0001] The utility model belongs to the technical field of plate-ring type sensor processing, in particular to a plate-ring type sensor diaphragm pressure plate positioning welding device. Background Art

[0002] A plate ring sensor is a weighing sensor. It is mainly composed of an elastomer, a strain gauge, a sealed shell, etc. The elastomer is usually in the shape of a plate ring and has high strength and rigidity. The strain gauge is attached to the elastomer. When the sensor is subjected to external force, the elastomer deforms and the resistance value of the strain gauge changes accordingly. By measuring the resistance change of the strain gauge, the magnitude of the external force can be determined.

[0003] During the production process of plate-ring type sensors, the diaphragm pressure plate needs to be welded to the specified position of the sensor. However, during the welding process, due to the small size and light weight of the diaphragm pressure plate, it is difficult to accurately position the diaphragm pressure plate, which can easily lead to inaccurate welding position and affect the quality of the sensor. For this reason, it is necessary to provide a plate-ring type sensor diaphragm pressure plate positioning welding device. First, the diaphragm pressure plate is elastically pressed and positioned to prevent it from moving during the welding process. At the same time, the welding head is driven by the rotating assembly to rotate around the diaphragm pressure plate for welding, thereby improving the welding accuracy and efficiency and ensuring the production quality and production speed of the sensor.

[0021] Hereinafter, embodiments of the plate-ring type sensor diaphragm pressure plate positioning welding device of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 The plate-ring type sensor diaphragm pressure plate positioning welding equipment of an embodiment of the present invention is shown, comprising a welding table 1: an electric telescopic rod 2 is fixedly installed on the top of the front side of the welding table 1, the output end of the electric telescopic rod 2 is fixedly connected to a lifting tube 3, the inner cavity of the lifting tube 3 is slidably connected with a sliding pin 6, and the bottom end of the sliding pin 6 is fixedly connected to a pressure plate 7. Through the coordinated use of the sliding pin 6 and the pressure plate 7, the bottom end of the lifting tube 3 is elastically contacted with the diaphragm pressure plate, thereby avoiding rigid contact, squeezing the diaphragm pressure plate, and damaging the diaphragm pressure plate or the sensor. A spring 8 is sleeved on the surface of the sliding pin 6, and the bottom and top ends of the spring 8 are welded to the pressure plate 7 and the lifting tube 3 respectively. A welding head 4 is provided on the right side of the lifting tube 3, and a displacement seat 9 is fixedly connected to the surface of the welding head 4. A rectangular slide groove 10 adapted to the displacement seat 9 is provided on the right side of the top and bottom of the rotating frame 51. The right side of 51 is threadedly connected to a threaded rod 11, and the left end of the threaded rod 11 passes through the inner cavity of the rotating frame 51 and is rotatably connected to the displacement seat 9 through a bearing. The threaded rod 11 and the rectangular slide 10 are used in conjunction with each other to adjust the displacement seat 9 horizontally, so that the welding head 4 can be adjusted left and right, thereby enabling the welding head 4 to accurately reach the specified welding position, thereby improving the welding accuracy. A rotating assembly 5 is provided on the surface of the lifting tube 3, and the rotating assembly 5 includes a rotating frame 51 rotatably connected to the surface of the lifting tube 3. The surface of the lifting tube 3 has two positioning grooves 52 adapted to the rotating frame 51. A driving motor 53 is fixedly installed on the left side of the inner cavity of the rotating frame 51, and the output shaft of the driving motor 53 is fixedly connected to a driving gear 54. The bottom of the surface of the lifting tube 3 is fixedly connected to a force gear 55, and the driving gear 54 and the force gear 55 are meshed.

[0023] Working principle: When using the present invention, the user places the diaphragm pressure plate at the welding position of the sensor, and then turns on the electric telescopic rod 2. The electric telescopic rod 2 pushes the lifting tube 3 downward, so that the lifting tube 3 drives the sliding pin 6 and the pressure plate 7 to move downward until the bottom of the pressure plate 7 contacts the top of the diaphragm pressure plate. The spring 8 begins to contract. After the bottom end of the welding head 4 contacts the diaphragm pressure plate, the user turns on the driving motor 53. The driving motor 53 starts and drives the driving gear 54 to rotate. Due to the meshing transmission effect of the driving gear 54 and the force-bearing gear 55, The driving motor 53 is subjected to the reverse force to drive the rotating frame 51 to rotate, and the rotating frame 51 rotates with the lifting tube 3 as the rotation center, so that the rotating frame 51 drives the welding head 4 to rotate, and the bottom end of the welding head 4 revolves around the contact position of the diaphragm pressure plate and the sensor to weld the diaphragm pressure plate. Before use, the user can rotate the threaded rod 11, and the threaded rod 11 pushes the displacement seat 9 through the surface thread action, thereby adjusting the left and right positions of the welding head 4, so as to calibrate that the bottom end of the welding head 4 can accurately contact the welding position of the diaphragm pressure plate.

[0024] To sum up: the plate-ring type sensor diaphragm pressure plate positioning welding equipment, through the coordinated use of the electric telescopic rod 2, the lifting tube 3 and the sliding pin 6, elastically presses and positions the diaphragm, and then drives the welding head 4 to rotate around the diaphragm pressure plate through the setting of the rotating component 5, and welds the diaphragm pressure plate and the sensor contact position through the welding head 4, which can prevent the diaphragm pressure plate from moving during the welding process, enhance welding accuracy and efficient welding.
