Description

Technical Field

[0001] The invention belongs to the technical field of detection tooling and relates to a tooling for detecting whether a bolt is hollow or transparent. Background Art

[0002] The two mounting bolts of the level gauge are hollow so that the oil can enter the transparent tube of the level gauge through the bolts to display the tank level. Since the hollow channel of the bolt is T-shaped (or L-shaped) and the channel diameter is small, it is difficult to directly identify with the naked eye, and it is easy to cause blockage due to debris entering the inside without being discovered. For finished product inspection, it is impossible to accurately determine whether the oil is flowing. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a tool for detecting whether a bolt is hollow or transparent.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A tool for detecting whether a bolt is hollow or transparent comprises a base for mounting a liquid level meter to be measured, a pressure plate located above the base and movable up and down, and two intermediate interfaces fixedly mounted on the pressure plate and connectable to two end bolts of the liquid level meter to be measured; one of the two intermediate interfaces is also connected to an external inflation component through a pipeline, and the other is connected to a pressure switch for controlling the operation of a buzzer through a pipeline.

[0006] Furthermore, one end of the pressing plate is rotatably mounted above the base via a horizontally arranged pin shaft, and through strip grooves are processed on both lateral sides of the pressing plate, and a vertically fixed guide column passes through the strip groove.

[0007] Furthermore, the width of the strip groove matches the outer diameter of the guide post.

[0008] Furthermore, a tension spring is provided on the upper surface of the pressure plate to separate the middle interface from the end bolts.

[0009] Furthermore, the pressure plate is also provided with two spaced-apart transverse adjustment grooves, and the middle interface is slidably installed in the transverse adjustment grooves.

[0010] Furthermore, the middle interface is also provided with a locking piece which can lock and fix the transverse adjustment groove and the middle interface.

[0011] Furthermore, the intermediate interface is provided with an intermediate air passage that runs through from top to bottom, the lower end of the intermediate air passage matches the top of the end bolt of the measured liquid level meter, and the upper end of the intermediate air passage is connected to a pipeline connected to the external inflation component or pressure switch.

[0012] Furthermore, the base is composed of a horizontally fixed slide and two supports slidably arranged on the slide and matching the two ends of the measured liquid level meter.

[0013] Furthermore, the buzzer is a buzzer with a light.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) Overall inspection: Omit single-piece inspection and complete overall reliable inspection in assembly line production with high efficiency.

[0016] (2) Safe and reliable: The buzzer can ensure that product detection will not cause false alarms.

[0017] (3) Wide range of applications: The distance between supports and intermediate interfaces can be adjusted by using the slide and transverse adjustment groove to adapt to various specifications of liquid level gauges. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0022] Example 1

[0023] like Figure 1 In the liquid level meter shown in the figure, the end bolts 6 at both ends are hollow and connected to the transparent tube 10 in the middle. In order to detect the transparent effect of the end bolts 6 of the liquid level meter, please refer to Figure 1 As shown, this embodiment proposes a tool for detecting whether a bolt is hollow and transparent, including a base for mounting a measured liquid level meter 7, a pressure plate 4 located above the base and movable up and down, and two intermediate interfaces 5 fixedly mounted on the pressure plate 4 and connectable to two end bolts 6 of the measured liquid level meter 7, one of the two intermediate interfaces 5 is also connected to an air switch 3 of an external inflation component through a pipeline, and the other is connected to a pressure switch 1 for controlling the operation of a buzzer 2 through a pipeline.

[0024] Please see again Figure 1 As shown, one end of the pressing plate 4 is rotatably mounted above the base through a horizontally arranged pin shaft, and a through strip groove is processed on both sides of the pressing plate 4, and a vertically fixed guide column 12 is passed through the strip groove. The width of the strip groove matches the outer diameter of the guide column 12.

[0025] Please see again Figure 1 As shown, a tension spring 13 is also provided on the upper surface of the pressing plate 4 to separate the middle interface 5 from the end bolt 6. One end of the tension spring 13 is fixedly connected to the pressing plate 4, and the other end is fixedly connected to a fixing member located above the pressing plate 4.

[0026] Please see again Figure 1 As shown, the pressing plate 4 is also provided with two spaced transverse adjustment grooves 14, and the intermediate interface 5 is slidably installed in the transverse adjustment grooves 14. The intermediate interface 5 is also provided with a locking piece that can lock and fix the transverse adjustment grooves 14 and the intermediate interface 5. In this embodiment, the intermediate interface 5 can be designed as an inverted T-shaped structure, and only the upper part thereof can pass through the transverse adjustment grooves 14. A locking nut (which can be used as a locking piece) is threadedly sleeved on the upper part of the intermediate interface 5. By adjusting the locking nut and cooperating with the lower end of the intermediate interface 5, the intermediate interface 5 can be locked or loosened on the pressing plate 4.

[0027] Please see again Figure 1 As shown, the middle interface 5 is provided with an intermediate air passage that passes through from top to bottom, the lower end of the intermediate air passage matches the top of the end bolt 6 of the measured liquid level gauge 7, and the upper end of the intermediate air passage is connected to a pipeline connected to an external inflation component or a pressure switch 1. A sealing pad 11 may also be provided at the lower end of the intermediate air passage.

[0028] Please see again Figure 1 As shown, the base is composed of a horizontally fixed ram 9 and two supports 8 slidably arranged on the ram 9 and matching the two ends of the measured liquid level meter 7.

[0029] In this embodiment, in order to improve the warning effect, the buzzer 2 is a buzzer with a light.

[0030] During the specific operation, first place the measured liquid level meter 7 on the support 8, then fix the support 8 and the ram 9, adjust the distance between the two middle interfaces 5 to fit the holes of the end bolts 6 at both ends of the measured liquid level meter 7 and fix them. Manually press the pressure plate 4 to make the middle joint and the end bolts 6 closely connected to form a pneumatic passage, then step on the air switch 3 of the external inflation component to inflate the pneumatic passage. At this time, if the buzzer 2 sounds instantly and lights up, it means that the pneumatic passage is unobstructed, indicating that the inside of the measured liquid level meter 7 is transparent and qualified. If the buzzer 2 does not light up or sound, it indicates that the inside of the measured liquid level meter 7 is not transparent. If the buzzer 2 lights up and sounds with a delay, the system air path is unobstructed but not smooth, and the end bolts 6 must be further inspected.

[0031] After the test is completed, release the pressure plate 4 and the air switch 3, and the pressure plate 4 is lifted under the action of the tension spring 13, so that the middle interface 5 is separated from the end bolt 6 and leaves the area directly above the measured liquid level meter 7. Then, the measured liquid level meter 7 can be easily removed from the support 8.

[0032] In the above embodiments, unless otherwise specified, it means that the functional components used are conventional components in the art for realizing corresponding functions.

[0033] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
