Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for pressure gauge production, specifically to a positioning fixture for filling pressure gauges with oil. Background Technology

[0002] In the manufacturing process of pressure gauges, lubrication is a critical step, as its quality directly affects the measurement accuracy and service life of the pressure gauge. Currently, pressure gauge lubrication typically requires manual hand-holding or positioning on a simple support platform. However, manual hand-holding is prone to displacement due to hand tremors, while simple support platforms cannot be flexibly adjusted according to the pressure gauge specifications and lubrication requirements, making accurate positioning difficult. This not only reduces lubrication efficiency but may also lead to problems such as over- or under-lubrication or leakage, affecting product quality. Therefore, a positioning fixture for pressure gauge lubrication is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a positioning fixture for filling pressure gauges with oil in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for filling pressure gauges, characterized in that it includes a base mounted on a filling equipment platform, a slider slidably connected to the base, and a positioning component slidably connected to the slider and used to fix the pressure gauge; the positioning component includes a base plate slidably connected to the slider, a pair of support columns symmetrically arranged on the base plate, and semi-circular positioning plates respectively arranged at the top of the support columns and together forming a positioning space for accommodating the pressure gauge body; the semi-circular positioning plates have arc-shaped clearance grooves on their sides to avoid the bottom of the pressure gauge, and the tops of the two semi-circular positioning plates are not connected and form an oil filling clearance groove for providing operating space for the oil filling hole of the pressure gauge.

[0005] More preferably, the base is provided with a first guide rail, and the slider is provided with a second guide rail perpendicular to the first guide rail.

[0006] More preferably, the bottom of the slider is provided with a second guide groove that matches the first guide rail on the base, and the bottom of the base plate is provided with a second guide groove that matches the second guide rail.

[0007] More preferably, the base plate is provided with a second guide groove that penetrates the base plate and a locking screw for locking the base plate onto the slider.

[0008] More preferably, the inner sidewalls of the pair of support columns opposite each other are formed with grooves for accommodating pressure gauge connectors.

[0009] The beneficial effects of this utility model are as follows: This positioning fixture achieves flexible adjustment in the mutually perpendicular X and Y axis directions through the sliding connection between the base and the slider, and the sliding connection between the slider and the positioning component. This allows for precise alignment of the pressure gauge's oil filling hole with the working head of the oil filling equipment. Furthermore, this structure facilitates adaptation to positioning components of different specifications, expanding the fixture's applicability. The circular positioning space formed by a pair of semi-circular positioning plates in the positioning component provides a stable and enclosed embedding space for the pressure gauge body. The protruding structure at the bottom of the pressure gauge can be embedded in the arc-shaped clearance groove, ensuring stable placement. Simultaneously, the oil filling clearance groove formed at the top effectively avoids the pressure gauge's oil filling hole area, providing an unobstructed passage for oil filling operations and ensuring that oil can be accurately and smoothly injected into the pressure gauge. By setting the locking screw, after the positioning component is adjusted to the target position by sliding, tightening the locking screw will cause its end, which extends into the second guide groove, to gradually press against the outer wall of the second guide rail on the slider. As the locking force increases, the positive pressure between the locking screw and the second guide rail increases synchronously, thereby generating a static friction force sufficient to limit the relative sliding of the base plate and the slider, and finally achieving a stable locking of their relative positions.

[0012] The following description, in conjunction with the accompanying drawings, further illustrates the positioning fixture for oil filling of a pressure gauge according to this utility model.

[0013] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] See Figures 1-4 As shown, a positioning fixture for filling a pressure gauge is characterized by: a base 1 mounted on a filling equipment platform and a slider 2 slidably connected to the base 1; and a positioning component 3 slidably connected to the slider 2 and used to fix the pressure gauge. The positioning component 3 includes a base plate 31 slidably connected to the slider 2, a pair of support columns 32 symmetrically arranged on the base plate 31, and semi-circular positioning plates 33 respectively arranged at the top of the support columns 32 and together forming a positioning space for accommodating the pressure gauge body. The semi-circular positioning plates 33 have arc-shaped clearance grooves 331 on their sides to avoid the bottom of the pressure gauge. The tops of the two semi-circular positioning plates 33 are not connected and form an oil filling clearance groove 332 to provide operating space for the oil filling hole of the pressure gauge. The base 1, slider 2, and positioning component 3 are made of stainless steel or alloy materials. This positioning fixture achieves flexible adjustment in the mutually perpendicular X and Y axes through the sliding connection between the base 1 and the slider 2, and the sliding connection between the slider 2 and the positioning component 3. This allows for precise alignment of the pressure gauge's oil filling hole with the working head of the oil filling equipment. Furthermore, this structure facilitates adaptation to positioning components 3 of different specifications, expanding the fixture's applicability. The circular positioning space formed by a pair of semi-circular positioning plates 33 in the positioning component 3 provides a stable and enclosed embedding space for the pressure gauge body. The protruding structure at the bottom of the pressure gauge can be embedded in the arc-shaped clearance groove 331, ensuring stable placement. Simultaneously, the oil filling clearance groove 332 formed at the top effectively avoids the pressure gauge's oil filling hole area, providing an unobstructed passage for oil filling operations and ensuring that oil can be accurately and smoothly injected into the pressure gauge.

[0016] In one embodiment, the base 1 is provided with a first guide rail 11, and the bottom of the slider 2 is provided with a first guide groove 22 adapted to the first guide rail 11. The first guide rail 11 can be integrally formed with the base 1, or it can be installed on the base 1 as an independent component by means of bolt connection or other means. The two cooperate with each other to form a first sliding pair that allows the slider 2 to slide along a first direction. The slider 2 is provided with a second guide rail 21, and the bottom of the base plate 31 of the positioning component 3 is provided with a second guide groove 311 adapted to the second guide rail 21. The second guide rail 21 is integrally formed with the slider 2, or it can be installed on the slider 2 as an independent component by means of bolt connection or other means. The two cooperate with each other to form a second sliding pair that allows the positioning component 3 to slide along a second direction. The sliding directions of the first sliding pair and the second sliding pair are perpendicular to each other in the horizontal plane, thereby realizing the bidirectional flexible adjustment of the positioning component 3 in the plane.

[0017] In one embodiment, the base plate 31 is provided with a second guide groove 311 penetrating the base plate 31 and a locking screw 34 for locking the base plate 31 onto the slider 2; the base plate is provided with an internal threaded hole that matches the locking screw 34; by setting the locking screw 34, when the positioning component 3 is adjusted to the target position by sliding, the locking screw 34 is tightened, and its end extending into the second guide groove 311 will gradually press against the outer wall of the second guide rail 21 on the slider 2. As the tightening force increases, the positive pressure between the locking screw 34 and the second guide rail 21 increases synchronously, thereby generating a static friction force sufficient to limit the relative sliding of the base plate 31 and the slider 2, and finally achieving a stable locking of their relative positions.

[0018] In one embodiment, the inner sidewalls of the pair of support columns 32 are formed with grooves 321 for accommodating the pressure gauge connector; the grooves 321 can embed the connector connected to the pressure gauge body, which avoids interference between the connector and the support column 32, and also makes the pressure gauge more stable after positioning and less prone to shaking.

[0019] When using this utility model: select the matching positioning component 3 according to the specifications of the pressure gauge to be filled; first slide the slider 2 along the first guide rail 11 on the base 1, then slide the second guide groove 311 at the bottom of the base plate 31 of the positioning component 3 along the second guide rail 22 on the slider 2, adjust the position of the positioning component 3 in the horizontal plane, so that the predetermined oil filling hole position of the pressure gauge is aligned with the working head of the oil filling equipment.

[0020] After the positioning component 3 is adjusted to the target position, tighten the locking screw 34 on the base plate 31 to fix the base plate 31 and the slider 2 relative to each other, so as to prevent the position from shifting during subsequent operations.

[0021] Place the pressure gauge to be filled into the positioning space formed by the two semi-circular positioning plates 33, so that the bottom of the pressure gauge is embedded in the arc-shaped clearance groove 331 of the semi-circular positioning plate 33, and at the same time, embed the pressure gauge connector into the groove 321 of the inner side wall of the support column 32, and the end face of the outer ring of the pressure gauge abuts against the side of the semi-circular positioning plate 33, thus completing the positioning and fixing of the pressure gauge.

[0022] Align the working head of the oiling equipment with the oiling hole of the pressure gauge, and use the oiling clearance grooves 332 on the top of the two semi-circular positioning plates 33 to perform the oiling operation; after the oiling is completed, remove the pressure gauge.

[0023] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
