Description

Technical Field

[0001] This application relates to the technical field of pressure gauge cleaning, and specifically relates to a pressure gauge thread cleaning machine. Background Art

[0002] A pressure gauge refers to an instrument that uses an elastic element as a sensitive element to measure and indicate a pressure higher than the ambient pressure. It is extremely widely used and almost covers all industrial processes and scientific research fields. It can be seen everywhere in fields such as thermal pipelines, oil and gas transmission, water supply and gas supply systems, vehicle repair and maintenance factories, etc. Especially in the industrial process control and technical measurement processes, due to the high mechanical strength and convenient production of the elastic sensitive element of the mechanical pressure gauge, the mechanical pressure gauge has been more and more widely used.

[0003] Pressure gauges are usually connected by threads. The threads on the threaded connectors of pressure gauges are usually processed by cutting. In order to perform thread processing quickly and safely, lubricants such as lubricating oil are also applied during the processing of the threaded connectors of pressure gauges to reduce friction and prevent part damage. In this way, there will be residual lubricants on the surface of the parts after processing, and metal slag and dust will be mixed in the lubricants. Such parts cannot be used directly, so they need to be cleaned; however, currently, the parts are usually rinsed in water, and it is very difficult to thoroughly clean the threads. If the threads are not cleaned thoroughly, it is very likely to cause problems such as subsequent thread corrosion and friction damage. Utility Model Content

[0004] In view of this, this application provides a pressure gauge thread cleaning machine to solve the technical problem that the existing cleaning method fails to thoroughly clean the threads.

[0005] To achieve the above object, the present utility model provides the following technical solutions:

[0006] A pressure gauge thread cleaning machine includes:

[0007] An outer box body, the inner cavity of the outer box body includes an upper cavity and a lower residue collection cavity distributed up and down. The upper cavity includes a cleaning cavity. An insertion hole for inserting the pressure gauge thread head into the cleaning cavity is provided on the panel of the outer box body. The residue collection cavity is communicated with the cleaning cavity, and an elastic pressing mechanism for engaging with the necking part of the pressure gauge thread head is provided on the panel.

[0009] A nozzle provided on the outer box body and communicated with the liquid supply system.

[0010] Furthermore, the rotation directions of the two brush wheels of the brushing device that cooperate with each other are the same.

[0011] Further, the insertion hole is a gourd-shaped hole, and the pressure gauge threaded head inserted from the large hole section of the insertion hole enters the small hole section of the insertion hole under the action of the elastic pressing mechanism for limit clamping.

[0012] Furthermore, the elastic pressing mechanism includes a locking block slidably arranged on the panel and a spring acting on the locking block. The locking block is provided with an arc-shaped card slot that cooperates with the necking part of the pressure gauge threaded head.

[0013] Furthermore, a gland is provided on the outer side surface of the panel. A chute for slidably fitting with the locking block is formed between the gland and the panel. The spring is located in the chute, and the gland is provided with an avoidance hole corresponding to the position of the insertion hole.

Here, the illustrative implementation manners of the present application and their descriptions are used to explain the present application, but do not limit the present application.

[0029] Refer to Figures 1 to 7 As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, this embodiment provides a pressure gauge thread cleaning machine, which includes an outer box body 1, a brushing device 2 and a nozzle 3 connected to a liquid supply system. The inner cavity of the outer box body 1 includes an upper cavity and a lower residue collection cavity 13 distributed up and down. The upper cavity includes a cleaning cavity 110. An insertion hole 142 for inserting the pressure gauge thread head into the cleaning cavity 110 is provided on the panel 14 of the outer box body 1. The residue collection cavity 13 is connected to the cleaning cavity 110. An elastic pressing mechanism that engages with the necking part of the pressure gauge thread head is provided on the panel 14; the brush wheel 21 of the brushing device 2 is arranged in the cleaning cavity 110, and the pressure gauge thread head extends between two adjacent brush wheels 21. The brush wheel 21 rotates to brush the pressure gauge thread head; the nozzle 3 is arranged on the outer box body 1, and a cleaning liquid is sprayed on the pressure gauge thread head by the nozzle 3.

[0030] In this application, the outer box body 1 includes a main box shell 11 with an open end. Inside the main box shell 11, a transverse partition 18 is provided to divide the inner cavity into an upper cavity and a lower residue collection cavity 13. The upper cavity is divided into a power mechanism accommodation cavity 12 and a cleaning cavity 110 by a longitudinal partition 19 arranged inside the main box shell 11 and connected to the transverse partition 18. A panel 14 corresponding to the cleaning cavity 110 is provided at the opening of the main box shell 11. The motor 24 of the brushing device 2 and the transmission device are located in the power mechanism accommodation cavity 12, and the transmission device drives the corresponding brush wheel 21 to rotate. Among them, the transmission shaft 22 for installing the brush wheel 21 and the transmission wheel of the transmission device penetrates through the panel 14 and the longitudinal partition 19. An axial mounting hole 141 for installing the transmission shaft 22 is provided on the panel 14. A material dropping hole 181 corresponding to the position of the cleaning cavity 110 is provided on the transverse partition 18, which is used to discharge the flowing cleaning liquid and metal slag into the lower residue collection cavity 13. The setting of the longitudinal partition 19 can also prevent liquid from splashing and affecting the use function of the motor 24. Heat dissipation holes are provided on the back of the main box shell 11.

[0031] In this application, the two brush wheels 21 of the brushing device 2 that cooperate with each other rotate in the same direction. The two brush wheels 21 moving in the same direction are used to clean the threaded head, enabling the threaded head to rotate during the cleaning process, making the cleaning more comprehensive and thorough.

[0032] Preferably in this application, the transmission device is a belt transmission device, and the transmission wheel is a belt pulley 23. The belt transmission device has the advantages of smoothness and low noise compared with chain transmission and gear transmission.

[0033] In this application, the transmission device may include two or three or four belt pulleys 23. When the transmission device has two belt pulleys 23, it correspondingly drives two brush wheels 21 to rotate, and the cleaning of one pressure gauge threaded head is completed at one time. When the transmission device has three belt pulleys 23, two cleaning channels can be formed, and the cleaning of two pressure gauge threaded heads can be completed at one time. When the transmission device has four belt pulleys 23, two or four cleaning channels can be formed. When the brush wheels 21 are paired in twos, two cleaning channels are formed. When the brush wheels 21 are distributed at the four corners along the ring and gathered together, four cleaning channels can be formed.

[0034] Preferably in this application, the transmission device includes two belt pulleys 23, and the two belt pulleys 23 are distributed vertically, so that the two brush wheels 21 are distributed vertically. When there are multiple sets of brushing devices 2, it can prevent the upper brush wheel 21 from affecting liquid spraying and also prevent unstable operation due to too high a center.

[0035] Preferably in this application, there are two sets of brushing devices 2, and the widths of the cleaning channels of the two sets of brushing devices 2 are different, so that pressure gauge threaded heads with different diameters can be cleaned.

[0036] In this application, the motor 24 can also be externally arranged.

[0037] In the present application, a pull-out box 17 is provided in the residue collection chamber 13. By using the pull-out box 17, cleaning of the residual night and residue can be avoided.

[0038] In the present application, the residue collection chamber 13 can also discharge the residue and residual night through a liquid discharge pipe.

[0039] In this application, preferably, Figure 7 As shown, the insertion hole 142 is a gourd hole, and the pressure gauge threaded head inserted from the large hole section of the insertion hole 142 enters the small hole section of the insertion hole 142 under the action of the elastic pushing mechanism for limited engagement. The neck portion of the pressure gauge threaded head slides into the small hole section of the insertion hole 142 so that the panel 14 is engaged in the neck portion, realizing the up and down and front and back limit of the pressure gauge threaded head. The elastic pressing of the elastic pushing mechanism is used to hold the pressure gauge threaded head against the panel 14, realizing the left and right limit of the pressure gauge threaded head. The use of the elastic pushing mechanism makes it easy to change the material of the pressure gauge threaded head, improves the cleaning efficiency, and does not hinder the rotation of the pressure gauge threaded head during the cleaning process. The gourd hole enables the pressure gauge threaded head to be positioned and installed at one time, which is convenient for installation.

[0040] In the present application, the insertion hole 142 can also be an arc-shaped groove that can match the diameter of the neck portion of the pressure gauge threaded head. The neck portion of the pressure gauge threaded head is pressed into the arc-shaped groove using an elastic pushing mechanism, and the panel 14 is inserted into the neck portion, thereby realizing the up and down, front and back, left and right limiting of the pressure gauge threaded head.

[0041] In the present application, the elastic pushing mechanism includes a locking block 16 slidably disposed on the panel 14 and a spring 111 acting on the locking block 16 , and the locking block 16 has an arc groove that cooperates with the neck portion of the threaded head of the pressure gauge.

[0042] In this application, if Figure 5 As shown, a pressure cover 15 is installed on the outer surface of the panel 14 by bolts, and a slide groove that slides with the locking block 16 is formed between the pressure cover 15 and the panel 14. The spring 111 is located in the slide groove, and the pressure cover 15 has an avoidance hole 151 corresponding to the position of the insertion hole 142. The use of this structure can make the locking block 16 hidden, and can avoid the need to increase the thickness of the panel 14 when the locking block 16 is installed on the panel 14. At the same time, through the setting of the pressure cover 15, the strength of the insertion hole 142 of the panel 14 can be increased, so that the panel 14 is not easily deformed.

[0043] When the present application is used, first push the locking block 16 away to expose the large hole section of the insertion hole 142, insert the threaded head of the pressure gauge and release the locking block 16, automatically push the threaded head of the pressure gauge into the cleaning channel, and the motor 24 starts to work, driving the belt transmission device to work, and then driving the brush wheel 21 to rotate, and the nozzle 3 sprays cleaning fluid to clean the threaded head of the pressure gauge.

[0044] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the embodiments of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
