Technical Field
[0001] This utility model relates to the field of instrument assembly equipment technology, and in particular to a pressure gauge assembly and positioning workbench. Background Technology
[0002] Pressure gauges are crucial industrial instruments whose core function is to accurately measure and visually display the pressure of fluids within pipes or containers, transforming intangible pressure into clear, visible scales or digital readings. As a "guardian" of system safety, they continuously monitor pressure, providing vital early warnings to prevent explosions or leaks caused by overpressure, thus protecting life and property. As a "command stick" for process control, they provide real-time data feedback to automated systems, ensuring stable operation of production processes under optimal pressure, impacting product quality and energy efficiency. Simultaneously, they serve as a "stethoscope" for fault diagnosis, analyzing pressure fluctuations to predict potential equipment problems, enabling predictive maintenance, and are also essential for energy management and trade settlement. Therefore, the accuracy and reliability of pressure gauges are the cornerstone of industrial safety, efficiency, and economy, directly dependent on the precision of their assembly, highlighting the critical value of high-end assembly positioning workbenches.
[0003] Traditional pressure gauge assembly has the following shortcomings: On the one hand, traditional physical fixtures need to be frequently changed and adjusted for different product models. Because they rely on molds and clamps of specific shapes, the changeover process is cumbersome, time-consuming and has very low flexibility. On the other hand, traditional assembly relies on human eyes and manual alignment of screw holes. Due to the unavoidable visual fatigue and individual differences, the positioning accuracy is poor, the consistency is low and the production efficiency bottleneck is prominent. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressure gauge assembly and positioning workbench. This workbench integrates a flexible clamping system based on an electromagnet matrix with a machine vision-based precision positioning system, achieving significant improvements: the flexible clamping system instantly reconstructs the magnetic mold via software commands, enabling zero-physical changeover and rapid adaptation to multiple models, greatly enhancing production flexibility and changeover efficiency; simultaneously, the machine vision system, through real-time image recognition and coordinate comparison, drives a high-precision fine-tuning platform to automatically correct its posture, achieving sub-millimeter-level precision alignment, completely eliminating human error, and improving assembly accuracy, first-pass yield, and production automation. These two technologies work synergistically to create a complete and advanced solution that meets the assembly needs of various high-precision pressure gauges.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A pressure gauge assembly and positioning workbench includes a support platform, a slide rail fixedly connected to the top of the support platform, an electric slide table mounted on the top outer wall of the slide rail, an mounting block fixedly connected to the top of the electric slide table, a positioning component installed inside the mounting block, a fixed bracket fixedly connected to the rear top of the support platform, a fixed rod fixedly connected to the bottom of the fixed bracket, a pneumatic actuator fixedly connected to the top of the fixed rod, and an assembly component mounted on the actuating end of the pneumatic actuator.
[0006] Furthermore, the positioning component includes a control board snapped into the mounting block, and an electromagnet matrix is provided on the top of the control board.
[0007] Furthermore, an industrial camera is mounted on the top front end of the fixed bracket to compare the pressure gauge image on the top of the mounting block with the theoretical image pre-stored inside the system.
[0008] Furthermore, the assembly includes a mounting sleeve rotatably connected to the actuating end of the pneumatic actuator, guide grooves are provided on both sides of the fixed rod, the rear end of the mounting sleeve is fitted onto the outer wall of the fixed rod, and the internal slider passes through the inside of the guide groove.
[0009] Furthermore, a motor is fixedly connected to the top front end of the mounting sleeve, and a tool head is sleeved on the outer wall of the drive end of the motor.
[0010] Furthermore, a spring clip is installed at the bottom of the drive end of the motor, and the outer end of the spring clip is engaged with the top of the tool head.
[0011] Furthermore, a detection port is provided on one side of the top of the support platform, and placement slots are provided on both sides of the top of the support platform.
[0012] Furthermore, a control panel is installed on one side of the front end of the support platform.
[0013] This utility model has the following beneficial effects: In this invention, the operator selects or draws the outline and positioning points of a specific pressure gauge casing via a control panel. The control system then generates corresponding control commands, precisely activating the electromagnet units at the corresponding coordinates on the worktable. This forms an adaptive magnetic array clamp that perfectly matches the product's shape, achieving reliable adsorption and precise positioning of the metal casing. For different pressure gauge models, only pre-stored graphics need to be called up or redrawn in the software interface, improving production line changeover efficiency.
[0014] In this invention, an industrial camera captures real-time images of the dial to be assembled, accurately calculates the real-time center coordinates of the dial's screw holes, and compares them with a pre-stored coordinate model in the system to calculate the directional offset. Subsequently, the control system sends this offset to the actuator driving the high-precision fine-tuning platform, automatically adjusting the dial's pose to ensure precise alignment of the screw holes with the screwdriver's landing point. This eliminates manual hole alignment errors and improves assembly accuracy and first-pass yield. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1 and Figure 2This utility model provides an embodiment of a pressure gauge assembly and positioning workbench, including a support platform 1. A slide rail 8 is fixedly connected to the top of the support platform 1. An electric slide 10 is installed on the top outer wall of the slide rail 8. The electric slide 10 slides on the slide rail 8 through precise control of its internal servo motor, which is an important mechanism for fine adjustment. A mounting block 4 is fixedly connected to the top of the electric slide 10. A positioning component is installed inside the mounting block 4. A fixed bracket 5 is fixedly connected to the rear side of the top of the support platform 1. A fixed rod 16 is fixedly connected to the bottom of the fixed bracket 5. A pneumatic actuator 6 is fixedly connected to the top of the fixed rod 16. When the control system issues a command, the electromagnetic reversing valve is energized and switches the air path, precisely introducing filtered and pressure-regulated clean compressed air into the cylinder, pushing the piston and piston rod to move linearly, thereby providing a fast and powerful linear thrust for the pressing, clamping, or stamping processes of the pressure gauge. After the action is completed, the electromagnetic valve reverses, the airflow direction changes, and the piston resets under the action of air pressure or spring force, realizing a complete working cycle. The device features rapid response, high output force, and easy control. The pneumatic actuator 6 has an assembly component installed at its actuation end. A test port 2 is provided on one side of the top of the support platform 1 to test the assembled pressure gauge and ensure product qualification. Placement slots 3 are provided on both sides of the top of the support platform 1. The interior of the placement slots 3 can hold different tool heads 9, such as different types of screwdrivers. A control panel 7 is installed on one side of the front end of the support platform 1. The control panel 7 controls the electromagnet matrix 12 to achieve rapid positioning of different types of pressure gauges.
[0019] Specifically, the system utilizes an electric slide 10 integrated on the support platform 1, a pneumatic actuator 6, and an electromagnet matrix 12 driven by a control panel 7, working in concert. Its core working principle is as follows: First, the electromagnet matrix 12 generates an adaptive magnetic mold according to instructions, enabling flexible and rapid positioning of the metal gauge case; then, the electric slide 10 drives the mounting block 4 for precise fine-tuning, ensuring accurate alignment between the dial and the gauge case; finally, the pneumatic actuator 6 drives the assembly components to complete assembly operations such as press-fitting or screw tightening. This design enables rapid changeover and high-precision assembly of multiple pressure gauge models, significantly improving production efficiency and product consistency.
[0020] Reference Figure 3 and Figure 4The mounting block 4 is internally snapped into the control board 11. The control board 11, acting as the system's command center, receives instructions from the host computer or user input, parses pre-stored contour graphic data through its internal processor, and outputs precise positioning pulse control signals. An electromagnet matrix 12, consisting of a rectangular array of multiple smaller electromagnets, is mounted on the top of the control board 11. Each individual electromagnet is electrically controlled to form a magnetic attraction area on the worktable corresponding to the mold, thus fixing the mold in place. The electrical signals output from the control board 11 drive the circuit switches of specific coordinate units, instantly energizing and magnetizing the corresponding electromagnets, generating a strong attraction force. Unselected units remain de-energized and non-magnetic, thereby precisely "drawing" the shape corresponding to the mold on the worktable. A magnetic mold that perfectly matches the shape of the workpiece enables flexible and digital positioning of the metal workpiece. An industrial camera 18, which is a CCD camera, is installed at the top front end of the fixed bracket 5 to compare the pressure gauge image on the top of the mounting block 4 with the theoretical image stored in the system. The actuator 6 is rotatably connected to the mounting sleeve 13. Guide grooves 17 are opened on both sides of the fixed rod 16. The rear end of the mounting sleeve 13 is fitted onto the outer wall of the fixed rod 16, and its internal slider passes through the inside of the guide groove 17. A motor 14 is fixedly connected to the top front end of the mounting sleeve 13. A tool head 9 is fitted onto the outer wall of the drive end of the motor 14. A spring clip 15 is installed at the bottom of the drive end of the motor 14, and the outer end of the spring clip 15 is engaged with the top of the tool head 9.
[0021] Specifically, the control board 11 parses the instructions and drives the electromagnet matrix 12 to generate a customized magnetic mold, precisely positioning the dial case fixed on the mounting block 4. Simultaneously, the industrial camera 18 on the fixed bracket 5 acquires and compares images of the dial, feeding back the positional deviation data to the system, which then drives the electric slide 10 for compensatory fine-tuning. After alignment, the pneumatic actuator 6 pushes the mounting sleeve 13 down steadily along the guide groove 17 of the fixed rod 16, while the motor 14 drives the tool head 9, which is quickly changed by the spring clip 15, to perform precision assembly. This structure integrates visual positioning, electromagnetic flexible clamping, and automatic execution functions, achieving full-process automation and high-precision control.
[0022] Working principle: After the operator selects the product model through the control panel 7, the control board 11 drives the electromagnet matrix 12 to generate a magnetic positioning mold that matches the case; the industrial camera 18 on the fixed bracket 5 acquires images of the dial on the mounting block 4, calculates the positional deviation through visual comparison, and instructs the electric slide table 10 to make precise fine adjustments along the slide rail 8 to achieve accurate alignment; after alignment is completed, the pneumatic actuator 6 pushes the mounting sleeve 13 to descend steadily along the guide groove 17 of the fixed rod 16, while the motor 14 drives the tool head 9, which is quickly installed through the spring buckle 15, to complete the final assembly operation.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
