Description

Technical Field

[0001] This utility model relates to the technical field of temperature and pressure gauge processing equipment, specifically to a pressure gauge base processing device. Background Technology

[0002] A thermo-pressure gauge is an instrument that integrates both temperature and pressure measurement functions. Combining temperature and pressure sensing components, it can monitor temperature and pressure parameters in pipelines, equipment, or the environment in real time, and is widely used in meteorological observation, outdoor exploration, aviation, and maritime fields. Due to the manufacturing process, the axial pressure gauge base requires soldering not only to the Bourdon tube but also to a machined hole on the side of the base that needs to be plugged. Because of the structural characteristics of this hole and the difficulty of the soldering process, incomplete soldering is prone to occur, resulting in a loose connection gap between the machined hole and the solder. This leads to air leakage during subsequent use or testing, severely affecting the gauge's measurement accuracy and reliability.

[0003] The existing solution involves pre-inserting copper beads into the machining hole and then sealing it. The insertion of copper beads in the current processing scheme relies entirely on manual hammering by workers. Affected by human factors such as the workers' skill level and force control, the insertion of copper beads on a single machine base takes a long time, resulting in low overall processing efficiency, which is difficult to meet the efficiency requirements of large-scale production.

[0007] The mold is fixed and has a stamping pin inserted on the side for stamping copper balls;

[0008] The copper ball is placed inside the fixed mold, and a stamping baffle is sleeved on the outside of the stamping ejector pin. The stamping baffle is used to drive the stamping ejector pin.

[0009] As a further description of the above technical solution, the two ends of the cylinder are connected to the fixing plate, and the fixing plate is connected to the base plate.

[0010] As a further description of the above technical solution, the end of the piston rod is connected to the punch nut.

[0017] As a further description of the above technical solution, the axis of the stamping hole is perpendicular to the axis of the placement hole.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this invention, a cylinder drives a piston rod to move a punch nut at the end, which in turn pushes a stamping baffle and an internal stamping pin forward along the stamping hole inside the fixed mold, thereby stamping the copper ball into the machining hole on one side of the machine base. Then, it is sealed by soldering, which reduces the difficulty of inserting the copper ball and effectively reduces the phenomenon of poor soldering after soldering the machining hole.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, in one embodiment, a pressure gauge base processing device includes: a cylinder 1 and a fixed mold 4;

[0029] Among them, the cylinder 1 has a piston rod 2 installed at the output end, which is used to drive the punch nut 3 connected to the end to achieve linear motion; correspondingly, the side of the fixed mold 4 is equipped with a stamping pin 5, which is used to accurately stamp the copper ball 6 pre-placed inside the fixed mold 4 to the target position.

[0030] Specifically, the copper ball 6 is placed inside the fixed mold 4, and the ejector pin is fitted with a stamping baffle 7. When the cylinder 1 receives the action command, the linear thrust of the piston rod 2 can directly act on the stamping baffle 7. The stamping baffle 7 then evenly transmits the thrust to the stamping ejector pin 5. Finally, through the axial movement of the ejector pin, the copper ball 6 inside the fixed mold 4 is smoothly and accurately stamped into the pre-set processing hole on one side of the machine base 10, thus realizing the automatic insertion of the copper ball 6.

[0031] For example, the top two sides of the cylinder 1 are connected to the air supply end through pipelines, and the two ends of the cylinder 1 are detachably connected to the fixing plate 8 through bolts and other fasteners, which facilitates the installation, debugging and subsequent maintenance and replacement of the cylinder 1; correspondingly, the fixing plate 8 is detachably connected to the base plate 9 through bolts and other fasteners, ensuring that the stamping accuracy will not be affected by factors such as vibration during the processing.

[0032] Furthermore, the end of the piston rod 2 is connected to the punch nut 3 by means of threaded connection or welding, and the end face of the punch nut 3 is parallel to the end face of the stamping baffle 7. This ensures that the thrust transmitted by the piston rod 2 is evenly applied to the stamping baffle 7, and avoids the stamping pin 5 from becoming skewed due to force deviation, thereby ensuring the stability and accuracy of the copper ball 6 stamping process.

[0033] Please continue reading. Figures 1-4 In this embodiment, a placement groove 41 is provided in the middle of the fixed mold 4, and the outer contour of the placement groove 41 fits the middle contour of the machine base 10, which can form a reliable positioning constraint on the machine base 10 and prevent the machine base 10 from shifting or shaking during the stamping process.

[0034] Furthermore, the top of the fixed mold 4 has a downward-facing placement hole 42 for placing the copper ball 6 to be stamped from the top of the fixed mold 4; correspondingly, a stamping hole 43 is provided through one side of the inside of the fixed mold 4, so that the stamping pin 5 can stamp the copper ball 6 into the processing hole on one side of the machine base 10 along the stamping hole 43.

[0035] Specifically, the punching hole 43 is connected to the middle of the placement hole 42, and the axis of the punching hole 43 is perpendicular to the axis of the placement hole 42, ensuring that the copper ball 6 falling from the placement hole 42 is exactly on the path of the punching hole 43, so that the punching pin 5 can accurately contact and push the copper ball 6 during the advancement process, avoiding the copper ball 6 from getting stuck or...

[0036] Working principle: First, the end of the machine base 10 to be processed is inserted into the placement groove 41 of the fixed mold 4 according to the positioning requirements. The precise fixation of the workpiece is achieved by the tight fit between the placement groove 41 and the contour of the machine base 10. Then, the operator puts the copper ball 6 into the placement hole 42 at the top of the fixed mold 4. Under the action of gravity, the copper ball 6 falls along the placement hole 42 and finally falls into the connection between the stamping hole 43 and the placement hole 42. Then, the cylinder 1 is started. The cylinder 1 operates under the drive of compressed air, driving the piston rod 2 to push forward axially. The punch nut 3 at the end of the piston rod 2 moves forward accordingly, thereby pushing the stamping baffle 7 and the stamping pin 5 to impact forward along the axis of the stamping hole 43 inside the fixed mold 4. Under the action of impact force, the copper ball 6 in the preset position is stamped into the processing hole on one side of the machine base 10, completing the automatic implantation of the copper ball 6. After the copper ball 6 is implanted, the processing hole is then sealed by soldering.

[0037] Through the above technical solution, this application can effectively reduce the difficulty of manual operation and ensure that the copper ball 6 can be implanted into the processing hole with appropriate force and position, providing a reliable basic sealing structure for subsequent soldering and sealing, thereby effectively reducing the phenomenon of poor soldering caused by improper position or poor fit of the copper ball 6 after soldering of the processing hole.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
