Description

Technical Field

[0001] This utility model relates to the technical field of pressure gauge testing equipment, and in particular to a rapid pressure gauge testing equipment. Background Technology

[0002] Pressure gauges are instruments that use elastic elements as sensing elements to measure and indicate pressures higher than ambient pressure. They are extremely common, found in almost all industrial processes and scientific research fields. They are ubiquitous in areas such as heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Especially in industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used due to the high mechanical strength and ease of manufacture of their elastic sensing elements.

[0003] The existing published patent: CN202421262760.5 Pressure gauge combined testing fixture, by setting up a row of clamping mechanisms, using components such as ratchet, gripper, spring, lever and push rod, etc., rotating the lever, so that the upper end of the gripper is in fixed contact with the pressure gauge, can quickly and stably clamp and disassemble the pressure gauge, and effectively improve the stability and testing efficiency of the pressure gauge.

However, the upper surface of existing pressure gauges is generally made of glass. Fixing the pressure gauge by pressing the upper surface of the pressure gauge with the upper end of the clamp can easily crush the glass of the pressure gauge, thereby damaging the pressure gauge and reducing the safety of the pressure gauge rapid testing equipment.

[0053] Please see Figure 1-6 The present invention provides a technical solution: including a workbench 1, the upper surface of the workbench 1 having four sliding grooves 9, the sliding grooves 9 extending out of the lower surface of the workbench 1;

[0054] Among them, four first sliding blocks 4 are slidably sleeved in the four sliding grooves 9;

[0058] Furthermore, the four second sliding blocks 5 are slidably fitted onto the four first sliding blocks 4;

[0059] Among them, two first electric actuators 2 are fixedly connected to the lower surface of the worktable 1;

[0060] Among them, the telescopic ends of the two first electric actuators 2 are fixedly connected to the upper surface of the mounting plate 3;

[0063] Among them, four second electric actuators 8 are fixedly connected to the outer surfaces of the front and rear sides of the two fixed blocks 7;

[0064] Among them, the telescopic ends of the four second electric push rods 8 are fixedly connected to the corresponding second sliding blocks 5;

[0065] Among them, the two fixed rods 20 are fixedly connected to the four corresponding second sliding blocks 5;

[0066] Among them, multiple air injection tubes 21 are fixedly connected to corresponding fixed rods 20;

[0067] The hose 23 is fixedly connected to the upper surface of the corresponding air injection pipe 21, and the hose 23 is connected to the inside of the air injection pipe 21.

[0068] Furthermore, multiple positioning slots 10 are formed on the upper surface of the worktable 1, and the positioning slots 10 extend out of the lower surface of the worktable 1.

[0069] Two connecting rods 16 are rotatably sleeved on the worktable 1, and the connecting rods 16 pass through the corresponding positioning grooves 10.

[0070] Two worm gears 17 are fixedly connected to the left ends of two connecting rods 16;

[0071] Multiple sets of bidirectional threads 19 are formed on the outer surface of the connecting rod 16, and the bidirectional threads 19 are located in the corresponding positioning grooves 10.

[0072] Furthermore, the two positioning blocks 11 are threaded onto the two opposite threads of the corresponding bidirectional threads 19;

[0073] Among them, the two positioning blocks 11 are slidably connected to the corresponding positioning grooves 10;

[0074] The upper surface of the positioning block 11 extends out of the upper surface of the worktable 1 through the positioning groove 10;

[0084] Furthermore, the detection principle and method of the pressure gauge in this solution are existing technologies in the publicly disclosed patent: CN202421262760.5 Pressure Gauge Combination Detection Fixture, which will not be elaborated here;

[0085] Furthermore, during use, the pressure gauge to be tested is placed on the placement plate 18, with the pressure gauge's pipe opening facing the corresponding fixing rod 20. At this time, the first motor 13 is started, which drives the support rod 15 to rotate. The rotation of the support rod 15 synchronously drives the two worm gears 22 to rotate, which in turn drives the two corresponding worm wheels 17 to rotate, which in turn drives the two connecting rods 16 to rotate. The rotation of the connecting rods 16 synchronously drives the bidirectional thread 19 to rotate, which in turn drives the two corresponding positioning blocks 11 to move relative to each other or in opposite directions. This allows the two corresponding clamping blocks 12 to clamp and fix the outer surface of the pressure gauge, thereby positioning the pressure gauge. The fixing stability is high, and it will not damage the pressure gauge. It does not contact the glass surface of the pressure gauge, and the positioning is convenient and safe. It can fix multiple pressure gauges at the same time, making the positioning efficient and improving the efficiency of pressure gauge testing.

[0086] After the pressure gauge is fixed, the first electric actuator 2 is activated. The first electric actuator 2 can drive the mounting plate 3 to move up and down, which in turn drives the first sliding block 4 to move up and down, which in turn drives the second sliding block 5 to move up and down. This allows the height of the fixing rod 20 and the air injection pipe 21 to be adjusted so that the height of the air injection pipe 21 is more in line with the pipe opening of the current pressure gauge.

[0087] Activating the second electric actuator 8 causes the second sliding block 5 to move back and forth, which in turn moves the corresponding fixed rod 20 back and forth, causing the corresponding air injection pipe 21 to move closer to or further away from the pressure gauge. As the air injection pipe 21 approaches the pressure gauge, it slides into the pressure gauge's pipe opening, achieving connection between the air injection pipe 21 and the pipe opening. At this point, the pressure gauge can be tested, which is convenient and quick, thereby improving the efficiency of pressure gauge testing.

[0092] The second electric actuator 8 drives the second sliding block 5 to move back and forth, thereby synchronously driving the connection between the air injection pipe 21 and the pipe opening;

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
