Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a pressure gauge combined detection fixture. 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] Because the air inlet of the pressure gauge is small, if the air intake process is completed manually, it is easy to cause instability and make it difficult to complete the air intake process, resulting in low work efficiency. Therefore, a pressure gauge combination testing fixture is needed to solve the above problems. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this embodiment is a pressure gauge combination testing fixture, including:

[0031] The operating components include an operating table 19 and a vertical plate 14. The upper end face of the operating table 19 is symmetrically connected to both sides of the vertical plate 14.

[0032] The clamping component includes a fixed rod 7, an active plate 9, a movable plate 10, a moving plate 11, a gear 6, a toothed plate 5, a fixed plate 4, a first electric push rod 3, a support leg 2, a base plate 1, a sleeve 8, a support rod 18, a limiting groove 12, and a limiting rod 13.

[0033] The surface of the fixed rod 7 is rotatably sleeved inside the operating table 19. The inner wall of the active plate 9 is fixedly sleeved on the surface of the fixed rod 7. The upper end face of the active plate 9 is rotatably sleeved with the lower end face of the movable plate 10. The lower end face of the movable plate 10 is rotatably connected with the upper end face of the moving plate 11. The inner wall of the gear 6 is fixedly connected to the surface of the fixed rod 7. The surface of the gear 6 meshes with the surface of the toothed plate 5 for transmission. One side of the toothed plate 5 is fixedly connected to the surface of the fixed plate 4. The telescopic end of the first electric push rod 3 is fixedly connected to the surface of the fixed plate 4.

[0034] When the fixed rod 7 rotates, the direction of rotation drives the movement of the movable plate 10 and the moving plate 11, causing the inner wall of the moving plate 11 to slide within the limiting rod 13. When the moving plate 11 moves towards the sleeve 8 and abuts against the surface of the pressure gauge, the pressure gauge is clamped. The model of the first electric push rod 3 is set to MXQ.

[0035] The top end of the support leg 2 is fixedly connected to the lower end face of the operating table 19, and the bottom end of the support leg 2 is fixedly connected to the upper end face of the base plate 1.

[0036] When the support leg 2 supports the bottom of the operating table 19, the toothed plate 5 and the first electric push rod 3 can be installed.

[0037] The end of the first electric push rod 3 that is away from the fixed plate 4 is fixedly connected to the support foot, and the top of the fixed rod 7 rotates with the inner wall;

[0038] By setting the first electric push rod 3, the first electric push rod 3 can control the movement of the toothed plate 5 when it retracts, so that the toothed plate 5 can transmit power to the gear 6, thereby driving the rotation of the fixed rod 7.

[0039] The bottom end of the support rod 18 is fixedly connected to the upper end face of the operating table 19, and one side of the support rod 18 is fixedly connected to the surface of the sleeve 8.

[0040] The support rod 18 can support the sleeve 8 and make the fixed rod 7 move more smoothly and smoothly in the transmission connection plate.

[0041] The limiting groove 12 is opened on the lower end face of the moving plate 11, the lower end face of the limiting rod 13 is fixedly connected to the upper end face of the operating table 19, and the inner wall of the moving plate 11 is slidably sleeved on the surface of the limiting rod 13.

[0042] Working principle: When the pressure gauge needs to be tested, the pressure gauge is placed downward into the sleeve 8. Then, the first electric push rod 3 is driven to move the toothed plate 5 to the right. During the movement, the toothed plate 5 can control the rotation of the fixed rod 7 through the transmission of the gear 6. During the rotation of the fixed rod 7, the connecting plate is synchronously transmitted. At this time, the connecting plate drives the movable plate 10 to move, so that the movable plate 10 changes from the initial horizontal state to the inclined state. And through the pulling force, the movable plate 11 slides on the surface of the limit rod 13 and moves towards the sleeve 8. When the surface of the movable plate 11 abuts against the surface of the pressure gauge, the pressure gauge is clamped, ensuring that the pressure gauge is more stable and smooth during the subsequent testing process.

[0043] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, with the addition of a detection component. The detection component includes a second electric push rod 15, an air intake device 16, and an air intake head 17.

[0044] One end of the second electric push rod 15 is fixedly connected to the surface of the vertical plate 14, the telescopic end of the second electric push rod 15 is fixedly connected to the surface of the air intake device 16, and the surface of the air intake head 17 is fixedly installed on the inner wall of the air intake device 16.

[0045] The second electric push rod 15 can control the forward and backward movement of the air intake device 16. The model of the second electric push rod 15 is set as FNQ.

[0046] There are four air intake heads 17, with two air intake heads 17 forming a group;

[0047] Working principle: When it is necessary to detect the air intake of the pressure gauge, the pressure gauge is clamped, and then the second electric push rod 15 is driven to control the air intake device 16 and the air intake head 17 to move towards the pressure gauge, and the air intake head 17 is inserted into the air intake of the pressure gauge, which solves the problems of instability and low efficiency of manual hand holding.
