Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure regulator production, in particular to auxiliary equipment for assembling a gas pressure regulator. Background Art

[0002] A gas pressure regulator refers to a pressure regulating valve that reduces the pressure by filling high-pressure gas into a relatively large cavity through a small hole. In fact, it relies on cut-off pressure reduction. One side of the diaphragm or piston is the outlet cavity, and the other side is the artificial pressure. The valve stem that controls the size of the small hole is connected to the diaphragm (piston). In this way, as long as a fixed pressure is given, the pressure in the outlet cavity will always be equal to this pressure, thereby achieving a pressure regulation effect.

[0003] When the gas pressure regulator is produced, a certain space is required for pressure regulation and diaphragm installation. Generally, the edge of the cavity is connected by a flange. During the production process, the flange needs to be fixed with bolts. In order to ensure the sealing effect, the flange of the gas pressure regulator needs to be fixed with densely distributed bolts. When assembling the gas pressure regulator during the production process, the bolts on the surface of the flange need to spend more time. Not only does it require frequent changes in the position of the pressure regulator to tighten the bolts, but it is also necessary to clamp and limit the nuts used to avoid rotation, which makes the installation extremely inconvenient. Utility Model Content

[0004] The utility model aims at the defects in the prior art and provides a gas pressure regulator assembly auxiliary device.

[0005] The utility model is realized through the following technical solutions:

[0006] A gas pressure regulator assembly auxiliary device comprises a control component, a limiting mechanism and a pressure regulator clamped on the inner side of the top of the limiting mechanism, the control component comprises a base, a support tube, a telescopic rod, a limiting sleeve and a foot pedal, the support tube is fixedly arranged in the middle of the upper surface of the base, the telescopic rod is installed on the upper surface of the base, the limiting sleeve is fixedly arranged at the telescopic end of the telescopic rod, the foot pedal is fixedly arranged at the bottom of the limiting sleeve, the limiting mechanism comprises a mounting seat, a positioning insert and a support plate, a mounting tube is arranged at the bottom of the mounting seat, the mounting seat is movably connected to the top of the support tube through the bottom mounting tube through a bearing, the positioning insert is fixedly arranged on the outside of the mounting seat, and the support plate is fixedly arranged on the top of the mounting seat.

[0007] In a preferred embodiment of the utility model, the voltage regulator includes a bottom flange, an upper end cover and a connecting pipe, and the bottom flange is connected to the upper end cover by bolts.

[0008] In a preferred embodiment of the utility model, a positioning block is provided at the bottom of the upper end cover, and a groove cooperating therewith is provided on the upper surface of the bottom flange;

[0009] A cavity is formed between the upper end cover and the bottom flange to provide space for the diaphragm and pressure relief. During installation, the positioning block at the bottom of the upper end cover cooperates with the slot on the upper surface of the bottom flange to facilitate the alignment of the mounting holes and the bolt installation work.

[0010] In a preferred embodiment of the utility model, the top of the support plate is provided with a mounting groove matched with the bottom flange, the bottom of the support plate mounting groove is provided with a clamping hole matched with the bolts used to connect the upper end cover and the bottom flange, and the bottom of the mounting seat is provided with a positioning groove matched with the connecting pipe;

[0012] In a preferred embodiment of the utility model, the limiting sleeve is sleeved on the outside of the support tube, and a slot matching with the positioning strip is opened on the inner side of the top of the limiting sleeve;

[0013] After stepping on the pedal downward, the limit sleeve applies pressure to the telescopic rod and causes it to move downward, so that the slot on the inner side of its top is separated from the positioning strip. At this time, the limit mechanism can be rotated to facilitate adjustment of the operating area. After loosening the pedal to allow the limit sleeve to cooperate with the positioning strip, the limit effect is achieved, which facilitates installation.

In addition, the rotation of the limit mechanism can be controlled during the installation process to change the operation area, thereby facilitating the installation work. During operation, the limit mechanism is controlled to be locked, thereby ensuring the installation effect of the gas pressure regulator, reducing the adjustment and bolt installation time during the assembly process, and facilitating the assembly work.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0023] like Figure 1-5 A gas pressure regulator assembly auxiliary device shown in the figure includes a control component, a limiting mechanism 6 and a pressure regulator 7 clamped on the inner side of the top of the limiting mechanism 6. The control component includes a base 1, a support tube 2, a telescopic rod 3, a limiting sleeve 4 and a pedal 5. The support tube 2 is fixedly arranged in the middle of the upper surface of the base 1, the telescopic rod 3 is installed on the upper surface of the base 1, the limiting sleeve 4 is fixedly arranged at the telescopic end of the telescopic rod 3, and the pedal 5 is fixedly arranged at the bottom of the limiting sleeve 4. The limiting mechanism 6 includes a mounting seat 61, a positioning insert 62 and a support plate 63. A mounting tube is arranged at the bottom of the mounting seat 61. The mounting seat 61 is movably connected to the top of the support tube 2 through a bearing through the bottom mounting tube. The positioning insert 62 is fixedly arranged on the outside of the mounting seat 61, and the support plate 63 is fixedly arranged on the top of the mounting seat 61.

[0024] Specifically, the voltage regulator 7 includes a bottom flange 8, an upper end cover 9 and a connecting pipe 10. The bottom flange 8 is connected to the upper end cover 9 by bolts. A positioning block is provided at the bottom of the upper end cover 9. A card groove matching therewith is provided on the upper surface of the bottom flange 8. A mounting groove matching therewith is provided at the top of the support plate 63. A card hole matching the bolts used to connect the upper end cover 9 and the bottom flange 8 is provided at the bottom of the mounting groove of the support plate 63. A positioning groove matching therewith is provided at the bottom of the mounting seat 61. The limiting sleeve 4 is sleeved on the outside of the support pipe 2. A slot matching therewith is provided on the inner side of the top of the limiting sleeve 4.

[0025] In this embodiment, first, the required nut is placed in the clamping hole that cooperates with the nut at the bottom of the mounting groove on the upper surface of the support plate 63, so that the nut is clamped in the corresponding clamping hole, and then the bottom of the voltage regulator 7 is installed, and the bottom flange 8 is clamped inside the mounting seat 61. At this time, the connecting pipe 10 at the bottom end of the bottom flange 8 is clamped in the positioning groove on the inner side of the bottom of the mounting seat 61, so that the mounting hole on the surface of the bottom flange 8 corresponds to the nut position in the support plate 63, and then the upper end cover 9 is installed. In order to facilitate the correspondence between the mounting hole on the surface of the upper end cover 9 and the mounting hole of the bottom flange 8, a positioning block is provided at the bottom of the upper end cover 9. After it is clamped in the positioning groove on the surface of the bottom flange 8, the mounting holes of the two are aligned.

[0026] Furthermore, during the bolt installation process, after the bolt is passed through the mounting holes on the upper end cover 9 and the bottom flange 8, the bottom end of the bolt can be directly connected to the nut in the support plate 63. Since multiple bolts are required to install the upper end cover 9 and the bottom flange 8, the foot pedal 5 is stepped down at this time to cause the limiting sleeve 4 to apply pressure to the telescopic rod 3, causing the telescopic rod 3 to shrink under pressure, and the limiting sleeve 4 moves downward. The slot on the inner side of the top of the limiting sleeve 4 is separated from the positioning strip 62 on the outer side of the mounting seat 61, and the limiting mechanism 6 can be rotated at the end of the support tube 2 to make the bolt processing position correspond to the worker's operating position. After loosening the foot pedal 5, the limiting sleeve 4 moves up so that the top slot is clamped to the bottom outer side of the positioning strip 62 to achieve a limiting effect, effectively reducing the need for workers to adjust the voltage regulator 7 during assembly, and facilitating the bolt installation work, thereby improving production efficiency.

[0027] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0028] In the description of the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "set", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
