Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauge calibration, in particular to a batch automatic calibration device for pressure gauges. Background Art

[0002] After the compulsory inspection of measuring instruments was stopped, the number of pressure gauges sent for inspection by the society and enterprises has increased dramatically. When the charging system was implemented before, enterprises and social organizations avoided inspection and verification if they could avoid it, and conducted inspections as little as possible, in order to spend less or no money. After the cancellation of the compulsory inspection of measuring instruments charges, the attitude of enterprises and social organizations changed, and they sent for inspection all the pressure gauges that could be inspected, those that could not be inspected, those that were in stock, and those that were newly purchased. This resulted in an exponential increase in the number of pressure gauges required for inspection, an exponential increase in the workload, an exponential increase in the load on equipment, a serious shortage of technical personnel, and the inability to complete the inspection and verification tasks and the inspection needs of enterprises, resulting in a sharp increase in the contradiction between supply and demand. Enterprises did not understand, society was dissatisfied, and the inspection and verification agencies were overwhelmed, which invisibly increased many contradictions and difficulties.

[0003] Traditional pressure gauge calibration equipment adopts a one-to-one calibration method, that is, one device is calibrated for one pressure gauge. When a large number of pressure gauges need to be calibrated, this method is extremely inefficient. Traditional pressure gauge calibration equipment often lacks effective fixing devices, which makes the pressure gauge easily displaced or shaken during the calibration process, which may not only affect the accuracy of the calibration results, but also cause damage to the equipment itself. Therefore, the utility model proposes a batch automatic calibration device for pressure gauges. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] The following is an explanation of the preferred embodiments of the device of the utility model.

[0025] See also Figure 1-5As shown, the pressure gauge batch automatic calibration equipment comprises a workbench 1, the top upper surface of the workbench 1 is provided with a correspondingly placed slide rail 2, the slide rail 2 is correspondingly provided with a drive box 4 and a calibration box 5 through a sliding block 3, the interior of the drive box 4 is provided with a clamping mechanism 6, and one side of the drive box 4 is linearly provided with a plurality of placement components 7, a transmission mechanism 8 is provided at the center of the upper surface of the workbench 1, the transmission mechanism 8 comprises a servo motor 801, the servo motor 801 is provided at the bottom center of the workbench 1, and the output end of the servo motor 801 is rotatably connected with a gear 802, a first special-shaped plate 803 is provided at the bottom of the drive box 4, a first rack 804 is provided on the inner side of one end of the first special-shaped plate 803, and a second special-shaped plate 805 and a second rack 806 are correspondingly provided on the other side of the calibration box 5, and the first rack 804 and the second rack 806 are respectively meshed with one side of the gear 802. Specifically, when the servo motor 801 is started, its output end drives the gear 802 to rotate. Since the first rack 804 and the second rack 806 are respectively engaged with one side of the gear 802, the rotation of the gear 802 will drive the first special-shaped plate 803 and the second special-shaped plate 805 to respectively drive the drive box 4 and the inspection box 5 to slide relative to each other on the slide rail 2.

[0026] The placement assembly 7 includes a connecting rod 701, and a placement sleeve 702 is fixedly connected to the side of the connecting rod 701 away from the drive box 4. An arc-shaped notch 703 is provided on the outer surface of one side of the placement sleeve 702 and is connected to the inside. An arc-shaped hole 704 is provided on the side wall of the inside of the placement sleeve 702 close to the connecting rod 701.

[0027] A pressure gauge 9 is placed in the circular sleeve 702 , and a water inlet 901 is provided on one side of the pressure gauge 9 . The water inlet 901 extends to the outside through an arc-shaped notch 703 . A connecting hole 501 is provided on one side of the calibration box 5 corresponding to the water inlet 901 .

[0028] Specifically, the placing circular sleeve 702 is designed to be a circular sleeve that matches the shape of the pressure gauge 9 and can stably accommodate the pressure gauge 9. The pressure gauge 9 is placed in the placing circular sleeve 702, ensuring the stability of the pressure gauge 9 during the calibration process. The water inlet 901 of the pressure gauge 9 extends to the outside through this arc-shaped notch 703, so that during the calibration process, the connecting hole 501 of the calibration box 5 can be conveniently connected to the water inlet 901, and the arc-shaped hole 704 provided in the placing circular sleeve 702 is used to accommodate the clamping block 606. When the driving box 4 and the calibration box 5 slide relative to each other along the slide rail 2 under the drive of the transmission mechanism 8, the water inlet 901 of the pressure gauge 9 will be accurately docked with the connecting hole 501, so that the calibration box 5 can be conveniently connected to the water inlet 901 through the connecting hole 501, thereby calibrating the pressure gauge 9.

[0029] In another embodiment provided by the present invention, Figure 4 and 5As shown, the clamping mechanism 6 includes a pushing member 601, a connecting plate 602, a connecting column 603, an annular top block 604, a guide column 605 and a clamping block 606. The output end of the pushing member 601 is movably connected to the connecting plate 602. The other side of the connecting plate 602 is linearly provided with a connecting column 603, and two connecting columns 603 form a group. One group of connecting columns 603 extends to the inside of the connecting rod 701, and the top of a group of connecting columns 603 is fixedly connected with an annular top block 604. A guide column 605 is provided between a group of connecting columns 603. The annular top block 604 is sleeved on the outside of the guide column 605. The guide column 605 is fixedly arranged inside the connecting rod 701, and one end of the guide column 605 is hinged with a clamping block 606. The clamping block 606 is arranged inside the arc hole 704, and the arc size of the arc hole 704 is adapted to the size of the clamping block 606.

[0030] Specifically, after the pressure gauge 9 is placed in the placement sleeve 702, the pusher 601 is started, and its output end pushes the connecting plate 602 and the connecting column 603 to move along the guide column 605 inside the connecting rod 701. The annular top block 604 on the top of the connecting column 603 moves accordingly and approaches the clamping block 606. Since the annular top block 604 is sleeved on the guide column 605, its sliding movement will push the clamping block 606 to move in the arc hole 704, thereby clamping the pressure gauge 9. This design ensures the stability of the pressure gauge 9 during the calibration process and reduces the error caused by shaking.

[0031] When in use, the pressure gauge 9 to be calibrated is placed in the placement sleeve 702 of the placement assembly 7 on one side of the drive box 4, ensuring that the water inlet 901 of the pressure gauge 9 is exposed to the outside through the arc-shaped notch 703 of the placement sleeve 702, and then the pusher 601 in the clamping mechanism 6 is started, and the connecting plate 602 and the connecting column 603 are pushed by the pusher 601 to move along the guide column 605 inside the connecting rod 701, and the circular top block 604 on the top of the connecting column 603 moves accordingly and approaches the clamping block 606. Under the push of the circular top block 604, the clamping block 606 moves inward along the arc-shaped hole 704, thereby clamping the pressure gauge 9 to ensure that it is stable and motionless, and the transmission mechanism 8 is started. The servo motor 801, the output end of the servo motor 801 drives the gear 802 to rotate. Since the first rack 804 and the second rack 806 are respectively meshed with one side of the gear 802, the rotation of the gear 802 will drive the first special-shaped plate 803 and the second special-shaped plate 805 to respectively drive the drive box 4 and the calibration box 5 to slide relative to each other on the slide rail 2. With the relative movement of the drive box 4 and the calibration box 5, the water inlet 901 of the pressure gauge 9 is accurately connected with the connecting hole 501 of the calibration box 5. At this time, the calibration box 5 can be conveniently connected to the water inlet 901 through the connecting hole 501, so as to calibrate multiple pressure gauges 9 at the same time, realize batch calibration, and greatly improve the calibration efficiency.
