Description

Technical Field

[0001] This utility model relates to the field of pressure transmitter testing technology, and in particular to a pressure transmitter assembly and calibration tool testing platform. Background Technology

[0002] Pressure transmitters are widely used in current industrial production and scientific research, and their performance and accuracy are directly related to the stability of production processes and the accuracy of scientific research results.

[0003] There are many existing pressure transmitter models with varying sizes and shapes. If they cannot be flexibly adapted, their application range will be limited, leading companies to purchase a variety of different testing equipment to meet calibration requirements, which increases costs. When faced with pressure transmitters of various specifications, operators need to frequently adjust or change clamping tools manually, which consumes a lot of time. Therefore, we propose a pressure transmitter assembly and calibration tool testing platform to solve this problem. Utility Model Content

Two sets of brackets are fixedly mounted on the top of the frame. Worms are rotatably mounted inside the two sets of brackets. A screw is rotatably mounted inside the frame. A worm gear is fixedly mounted on the top of the screw. A threaded sleeve is threadedly connected to the outer side of the screw. The cylinder has a first inclined block fixedly installed at the bottom of the threaded sleeve. Two sets of second inclined blocks are slidably installed inside the frame. The two sets of second inclined blocks are slidably installed on both sides of the first inclined block. Two sets of moving plates are slidably installed on one side of the frame. A sliding frame is fixedly installed on one side of each of the two sets of moving plates. A sliding seat is slidably installed inside each of the two sets of sliding frames. Multiple sets of buffer springs are fixedly installed between the two sets of sliding seats and the inner wall of the corresponding sliding frame. A clamp is fixedly installed on one side of each of the two sets of sliding seats. The outer side of the pressure transmitter body abuts between the two sets of clamps.

[0007] Preferably, the bottom of the base abuts against a worktable, four sets of limiting rods are slidably installed inside the worktable, a fixed seat is fixedly installed at the bottom of the four sets of limiting rods, four sets of movable seats are slidably installed at the top of the fixed seat, a support rod is hinged between the four sets of movable seats and the bottom of the worktable, a slide rod is fixedly installed inside the fixed seat, and a two-way lead screw is rotatably installed inside the fixed seat.

[0008] Preferably, a motor is fixedly installed on the top of the base, one end of the lead screw is fixedly installed on the output end of the motor, the motor is located inside the fixed frame, a guide groove is provided inside the fixed frame, and the lifting plate is slidably installed in the guide groove.

[0010] Preferably, one side of each of the two sets of inclined blocks 2 is provided with an inclined groove, and the two sides of the inclined block 1 are slidably installed in the corresponding inclined groove.

[0011] Preferably, a turntable is rotatably mounted on one side of one of the brackets, and one end of the worm gear is fixedly mounted on one side of the turntable, with the worm wheel meshing with the worm gear.

[0012] Preferably, the top of the fixed base is provided with two sets of sliding grooves, and the four sets of movable seats are slidably installed in the corresponding sliding grooves. The two ends of the slide rod are fixedly installed on both sides of one set of sliding grooves, and one end of the bidirectional lead screw is rotatably installed on one side of the other set of sliding grooves. A second motor is fixedly installed on one side of the fixed base, and one end of the bidirectional lead screw is fixedly installed on the output end of the second motor.

[0013] In this utility model, the pressure transmitter assembly and calibration tool test platform, through the cooperation between the motor, the lead screw and the lifting plate, realizes the lifting plate to move up and down under the restriction of the guide groove, thereby adjusting the height of the frame and realizing the adjustment of the installation height of the pressure transmitter body;

[0014] In this utility model, a pressure transmitter assembly and calibration tool test platform is provided.

[0015] This utility model features a rationally designed structure. Through the coordinated operation of a turntable, worm gear, bracket, and worm wheel, the worm wheel and screw are driven to rotate. The screw is connected to a threaded sleeve, which in turn drives the threaded sleeve to move the first inclined block up and down within the inclined grooves of two sets of second inclined blocks. Simultaneously, the two sets of second inclined blocks drive corresponding moving plates to move relative to each other within the T-slots. These moving plates then drive the relative movement of the sliding frame, sliding seat, buffer spring, and clamp, thereby quickly clamping and fixing the pressure transmitter body. The sliding frame, sliding seat, and buffer spring form a protective layer for the pressure transmitter body, preventing physical damage due to excessive clamping. Pressure changes and data can be directly observed through the pressure gauge, effectively ensuring the integrity and performance of the pressure transmitter remain unaffected and reducing the risk of equipment damage due to improper operation. This mechanism allows for flexible adjustment of the clamping position and force, achieving stable clamping and enhancing the versatility of the testing platform for different models of pressure transmitters.

[0024] In this embodiment, the bottom of the base 1 abuts against the worktable 23. Four sets of limiting rods 24 are slidably installed inside the worktable 23. A fixed seat 25 is fixedly installed at the bottom of the four sets of limiting rods 24. Four sets of movable seats 27 are slidably installed at the top of the fixed seat 25.

A two-way lead screw 30 is rotatably installed inside the fixed seat 25, realizing the lifting and lowering of the worktable 23 and the base 1, which can easily adapt to various different working scenarios.

[0025] In this embodiment, a motor 3 is fixedly installed on the top of the base 1, and one end of the lead screw 5 is fixedly installed on the output end of the motor 3. The motor 3 is located inside the fixed frame 4, and a guide groove 12 is provided inside the fixed frame 4.

[0026] In this embodiment, two sets of movable plates 17 are fixedly installed on one side of the corresponding inclined block 16. Two sets of T-slots are provided on one side of the frame 7.

Then, the pressure change and data can be directly observed through the pressure gauge 2.

[0031] The starter motor 3 drives the lead screw 5 to rotate. The lead screw 5 is threadedly connected to the lifting plate 6, thereby driving the lifting plate 6 to move up and down under the restriction of the guide groove 12, thereby adjusting the height of the frame 7 and realizing the adjustment of the installation height of the pressure transmitter body 21.

[0032] The starter motor 29 drives the bidirectional lead screw 30 to rotate, which in turn drives the two sets of movable seats 27 on one side to move relative to each other in the corresponding slide groove 26. The support rod 28 is hinged to the movable seats 27 and the worktable 23, so that the worktable 23 can be raised and lowered under the restriction of the limit rod 24. The raising and lowering of the worktable 23 causes the two sets of movable seats 27 on the other side to move relative to each other in the corresponding slide groove 26 under the drive of the corresponding support rod 28 and the restriction of the slide rod 31. This adjusts the height of the base 1 and the entire test platform to adapt to different usage scenarios or operator needs.
