Description

Technical Field

[0001] The utility model discloses a dust removal device suitable for explosion-proof motor shells with different diameters, belonging to the technical field of explosion-proof motor shell processing. Background Art

[0002] During the production process of explosion-proof motors, the shell of the explosion-proof motor needs to be painted to prevent the shell from rusting during the production process and causing damage to the motor. Before painting the shell, the surface of the shell needs to be dusted. Ultrasonic cleaning machines are often used to remove dust from the explosion-proof motor shell. Multiple explosion-proof motor shells are placed in the water storage tank of the ultrasonic cleaning machine, and then the ultrasonic cleaning machine can clean the dust attached to the explosion-proof motor shell when it is working. At present, the explosion-proof motor shell is generally placed directly in the water storage tank of the ultrasonic cleaning machine. Because one end of the explosion-proof motor shell is open and the other end has an axial hole for inserting the motor output shaft, after the explosion-proof motor shell is placed in the water in the water storage tank, if the explosion-proof motor shell is arranged horizontally, dust is easily deposited inside it, and it is necessary to rinse after taking out the explosion-proof motor shell. Utility Model Content

The utility model does not require re-flushing of the explosion-proof motor casing and is suitable for dust removal of explosion-proof motor casings of different diameters.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a dust removal device suitable for explosion-proof motor housings of different diameters, including an ultrasonic cleaning machine, a water storage tank is installed at the upper position inside the ultrasonic cleaning machine, a bottom plate is provided at the bottom of the water storage tank, a plurality of vertically arranged straight threaded barrels are evenly installed on the upper surface of the bottom plate, a stud is connected to the inner thread of the straight threaded barrel, two transversely arranged threaded heads are symmetrically installed on the outer surface of the upper end of the stud, an inner threaded barrel is threadedly connected to the threaded head, and a plurality of through holes are evenly opened on the upper surface of the bottom plate.

[0005] Furthermore, one end of the internal threaded barrel facing away from the stud is in a closed shape, and the closed end of the internal threaded barrel is processed with an internal hexagonal hole that matches with an internal hexagonal wrench.

[0006] Furthermore, a rubber sleeve bonded to the internal threaded barrel is sleeved on the internal threaded barrel, and both ends of the rubber sleeve are open.

[0007] Furthermore, a pin hole for inserting the extension rod is formed on the outer surface of the upper end of the stud, and the pin hole is arranged along the radial direction of the stud.

[0008] Furthermore, a rubber head is installed on the upper end of the stud, and the diameter of the rubber head is the same as the diameter of the stud.

[0009] Furthermore, a reinforcing rib is connected and fixed to the outer surface of the lower end of the straight threaded tube, and the reinforcing rib is connected and fixed to the bottom plate.

[0010] Furthermore, a blind hole is provided at the position where the threaded head of the stud is installed, and one end of the threaded head is connected and fixed in the blind hole.

[0011] Furthermore, a drain valve is installed on one side of the ultrasonic cleaning machine, and the drain valve is connected to the water storage tank.

[0012] Beneficial effects of the utility model:

[0013] 1. Place the bottom plate in the water storage tank. At this time, under the support of the bottom plate, the structure formed by the stud and the straight threaded barrel is arranged vertically. Two horizontally arranged threaded heads are installed on the upper end of the stud. Then, when the explosion-proof motor housing is placed in the water storage tank, the structure formed by the stud and the straight threaded barrel is inserted into the explosion-proof motor housing, and the side of the explosion-proof motor housing with the shaft hole is arranged upward. At this time, the length of the structure formed by the two threaded heads is greater than the inner diameter of the shaft hole, so the explosion-proof motor housing is arranged vertically. Then, when the explosion-proof motor housing is dust-removed by ultrasonic wave, the dust in the water will not settle on the inner surface of the explosion-proof motor housing, and there is no need to re-rinse the explosion-proof motor housing.

[0014] 2. Adjust the length of the stud in the straight thread barrel, so that the height of the structure formed by the stud and the straight thread barrel changes, so that the height of the structure formed by the stud and the straight thread barrel can be adjusted according to the size of the explosion-proof motor housing, so that explosion-proof motor housings of different sizes can be immersed in the water of the water storage tank.

[0015] 3. Adjust the length of the thread head in the internal thread barrel. At this time, the length of the structure formed by the thread head and the internal thread barrel changes, so that the length of the structure formed by the thread head and the internal thread barrel is greater than the inner diameter of the shaft hole. Therefore, when the explosion-proof motor housing is sleeved on the structure formed by the stud and the straight thread barrel, the stud will not pass through the shaft hole. It is suitable for the needs of supporting explosion-proof motor housings of different diameters and expands the scope of application. At the same time, the internal thread barrel plays a role in protecting the direct contact between the threads on the thread head and the explosion-proof motor housing, thereby protecting the thread head.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1 The utility model provides a technical solution: a dust removal device suitable for explosion-proof motor housings of different diameters, including an ultrasonic cleaning machine 1, a water storage tank 2 is installed at the upper position inside the ultrasonic cleaning machine 1, a drain valve 6 is installed on one side of the ultrasonic cleaning machine 1, and the drain valve 6 is communicated with the water storage tank 2. After opening the drain valve 6, it is convenient to discharge the water in the water storage tank 2. The internal structure and working principle of the ultrasonic cleaning machine 1 have been fully disclosed in the prior art, so they will not be repeated here.

[0023] See also Figure 2 and Figure 3 A bottom plate 13 is provided at the bottom of the water storage tank 2, wherein a plurality of through holes 14 are evenly provided on the upper surface of the bottom plate 13. The design of the through holes 14 facilitates water to flow through the bottom plate 13, making it convenient to lower the bottom plate 13 into the water storage tank 2 containing water or to take it out of the water storage tank 2.

[0024] See also Figure 3 A plurality of vertically arranged straight threaded tubes 11 are evenly installed on the upper surface of the bottom plate 13, and a reinforcing rib 12 is connected and fixed to the outer surface of the lower end of the straight threaded tube 11, wherein the reinforcing rib 12 is connected and fixed to the bottom plate 13. By installing the reinforcing rib 12 between the straight threaded tube 11 and the bottom plate 13, the mechanical strength of the connection between the straight threaded tube 11 and the bottom plate 13 is improved.

[0025] See also Figure 1 , Figure 2 and Figure 3, a stud 5 is connected with the inner thread of the straight threaded tube 11, and a rubber head 4 is installed on the upper end of the stud 5. The diameter of the rubber head 4 is the same as that of the stud 5. By installing a threaded head 10 on the stud 5, it is prevented that the stud 5 is in hard contact with the inner wall of the explosion-proof motor housing, so as to protect the stud 5 and the explosion-proof motor housing. Two transversely arranged threaded heads 10 are symmetrically installed on the outer surface of the upper end of the stud 5. A blind hole is opened at the position where the threaded head 10 of the stud 5 is installed, so that one end of the threaded head 10 is connected and fixed in the blind hole, thereby increasing the connection range between the threaded head 10 and the stud 5. The bottom plate 13 is placed in the water storage tank 2. At this time, under the support of the bottom plate 13, the structure formed by the stud 5 and the straight threaded tube 11 is arranged vertically, and two horizontally arranged threaded heads 10 are installed on the upper end of the stud 5, so as to place the explosion-proof motor housing. When in the water storage tank 2, the structure formed by the stud 5 and the straight threaded barrel 11 is inserted into the explosion-proof motor housing, and the side of the explosion-proof motor housing with the axial hole is arranged upward. At this time, the length of the structure formed by the two threaded heads 10 is greater than the inner diameter of the axial hole, so that the explosion-proof motor housing is arranged vertically, and then when the explosion-proof motor housing is dusted by ultrasonic wave, the dust in the water will not settle on the inner surface of the explosion-proof motor housing, and there is no need to re-rinse the explosion-proof motor housing. The length of the stud 5 in the straight threaded barrel 11 is adjusted, and then the height of the structure formed by the stud 5 and the straight threaded barrel 11 is changed, so that the height of the structure formed by the stud 5 and the straight threaded barrel 11 is adjusted according to the size of the explosion-proof motor housing, so that explosion-proof motor housings of different sizes are immersed in the water of the water storage tank 2.

[0026] See also Figure 1 , Figure 2 and Figure 3 , an internal threaded barrel 7 is threadedly connected to the threaded head 10, and the end of the internal threaded barrel 7 away from the stud 5 is closed. The closed end of the internal threaded barrel 7 is processed with an internal hexagonal hole 8 that matches the internal hexagonal wrench, so that one end of the internal hexagonal wrench is inserted into the internal hexagonal hole 8, which is convenient for using the internal hexagonal wrench to twist the internal threaded barrel 7. A rubber sleeve 3 is sleeved on the internal threaded barrel 7 and adhered to the internal threaded barrel 7. Both ends of the rubber sleeve 3 are open. The design of the rubber sleeve 3 makes the internal threaded barrel 7 flexibly contact with the inner wall of the explosion-proof motor housing. A pin hole 9 for inserting an extension rod is opened on the outer surface of the upper end of the stud 5. The pin hole 9 is arranged along the radial direction of the stud 5. The extension rod Inserted in the pin hole 9, it is convenient to use the extension rod to rotate the stud 5 and adjust the length of the threaded head 10 in the internal threaded tube 7. At this time, the length of the structure formed by the threaded head 10 and the internal threaded tube 7 changes, so that the length of the structure formed by the threaded head 10 and the internal threaded tube 7 is greater than the inner diameter of the shaft hole. Therefore, when the explosion-proof motor housing is sleeved on the structure formed by the stud 5 and the straight threaded tube 11, the stud 5 will not pass through the shaft hole. It is suitable for the needs of supporting explosion-proof motor housings of different diameters and expands the scope of application. At the same time, the internal threaded tube 7 plays a role in protecting the threads on the threaded head 10 from direct contact with the explosion-proof motor housing, thereby protecting the threaded head 10.
