Description

TECHNICAL FIELD

[0001] The utility model relates to pressure gauge calibration equipment technical field especially relates to a pressure gauge calibration equipment. BACKGROUND

[0003] The patent document with publication number 202322991951.7 discloses a pressure gauge calibration device, which belongs to the technical field of pressure gauge equipment. The pressure gauge calibration device moves the connecting plate to the placement seat direction by the electric telescopic rod, so that the clamping plate approaches the pressure gauge, and the placement seat completes the clamping and fixing of the pressure gauge. The soft clamping pad is used to buffer the pressure gauge and the clamping plate. When the pressure gauge reaches a certain degree of stress, the pressure is transmitted to the spring through the movable rod, and the deformation of the spring offsets the excess pressure of the pressure gauge, realizing the flexible clamping function of the calibration device, which is conducive to the normal production and calibration work. The motor drives the threaded rod to rotate, so that the moving block drives the lifting plate to move upward, and the clamping plate stably clamps the pressure gauge, so that the placement seat drives the pressure gauge to vertically rise, which is convenient for accurate docking with the interface to complete the docking work, realizing the automatic docking and calibration work of the calibration device.

[0004] The existing pressure gauge calibration device needs to clamp and fix the pressure gauge during use to avoid the position deviation of the pressure gauge, which affects the calibration result. Since the pressure gauge is usually a fragile product, a relatively flexible clamping plate needs to be used for clamping. However, the relatively flexible clamping plate is prone to wear after long-term use, and the overall structure of the relatively flexible clamping plate is fixed and integrated, which is inconvenient for workers to replace the relatively flexible clamping plate.

At the same time, tearing the clamping pad 14 outward can release the Velcro 16 and Velcro 13 installed at the lower rear end of the clamping pad 14.

[0027] Among them, reference Figure 3 and Figure 4 In a preferred embodiment, the protection mechanism includes a movable groove 24 disposed at the top of the calibration device 1. A mounting plate 21 is rotatably connected inside the movable groove 24. One end of the mounting plate 21 is fixedly connected to a spring assembly for resetting.

A housing 17 is fixedly connected to the outer wall of the calibration device 1. A pin 18 is slidably connected inside the housing 17. One end of the interface 19 is fixedly connected to a wire 20.

[0028] In this scheme, by setting up a protective mechanism, the operator can rotate the knob 2 on the outside of the calibration device 1, which will cause the connecting rod 23 fixedly connected at one end to rotate during the rotation of the knob 2. The rotation of the connecting rod 23 will cause the mounting plate 21 fixedly connected at one end to rotate, which will cause the mounting plate 21 to move the interface 19 fixedly connected at one end into the movable slot 24.

The spring clip 12 and the auxiliary sleeve 15 are arranged on the same central axis. By setting the spring clip 12, the connection between the clamping pad 14 and the clamping plate 10 can be released by pressing the spring clip 12 downward.

[0033] Furthermore, refer to Figure 3 and Figure 4 In a preferred embodiment, the Velcro 16 and the Velcro 13 are arranged on the same central axis and are connected by adhesive. By setting the Velcro 16 and the Velcro 13, the staff can be assisted in replacing and taking out the clamping pad 14.

[0034] Working principle: When staff use the calibration equipment;

[0035] First, by pressing down on the spring clip 12 inside the slot 11, the worker can make the spring clip 12 slide horizontally, which can disengage the spring clip 12 and the auxiliary sleeve 15, thereby releasing the limiting engagement between the clamping pad 14 and the clamping plate 10. At the same time, by tearing the clamping pad 14 outward, the Velcro 16 and Velcro 13 installed at the lower rear end of the clamping pad 14 can be unattached.

When the plug 18 is pulled out, the mounting plate 21 can be reset under the elastic force of the elastic assembly, so that the docking port 19 fixedly connected at one end with the wire 20 is turned out for use, and the pressure gauge is placed in the placement seat 5. The support plate 6 is driven by the front end electric telescopic rod 7 to move towards the placement seat 5, so that the clamping plate 10 is close to the pressure gauge placed in the placement seat 5, and the clamping and fixing of the pressure gauge are completed by cooperating with the placement seat 5. The pressure gauge and the clamping plate 10 are buffered by the clamping soft pad 14. When the pressure gauge reaches a certain degree of stress, the pressure is transmitted to the spring through the spring rod 8, and the deformation of the spring is used to offset the excessive pressure of the pressure gauge, so as to realize the flexible clamping function of the calibration device 1. The lifting plate 4 is driven by the electric lifting rod 9 to move upwards, and the pressure gauge is stably clamped by cooperating with the clamping plate 10, so that the placement seat 5 drives the pressure gauge to vertically ascend, and accurately completes the docking with the docking port 19 of the same center shaft, so as to calibrate the pressure gauge.
