Description

Technical Field

[0001] This utility model belongs to the field of aerospace fastener production technology, and specifically relates to an ultrasonic cleaning device for aerospace fasteners. Background Technology

[0002] Ultrasonic cleaning equipment for aerospace fasteners is a device specifically designed for cleaning fasteners (such as bolts and nuts) used in the aerospace industry. Due to their high precision and harsh working environment requirements, these fasteners must maintain extremely high cleanliness to ensure their performance and reliability. Ultrasonic cleaning utilizes the cavitation effect generated by high-frequency vibration in an aqueous medium to effectively remove tiny particles, grease, and other contaminants from the surface and crevices of the fasteners.

[0003] Existing ultrasonic cleaning devices for aerospace fasteners involve placing the fasteners to be cleaned inside a perforated barrel and then moving them into an ultrasonic cleaning device containing water for ultrasonic cleaning. However, after cleaning, the fasteners still need to be manually moved to a drying unit for drying, which increases unnecessary downtime, reduces overall production efficiency, and makes it impossible to achieve a continuous and uninterrupted cleaning process because it requires waiting for manual material handling and transfer. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an ultrasonic cleaning device for aerospace fasteners, which can automatically move the cleaned aerospace fasteners into the drying mechanism, centrifuge them to dry them, and then heat them to dry them, eliminating the need for manual transfer and greatly improving cleaning efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an ultrasonic cleaning device for aerospace fasteners, including an ultrasonic cleaning box, a drying box arranged on the left side of the ultrasonic cleaning box, multiple heating rods arranged on the left and right sides of the inner wall of the drying box, the multiple heating rods being arranged at equal intervals, a slide rail arranged between the rear side of the ultrasonic cleaning box and the drying box, a sliding frame slidably arranged inside the slide rail, a sliding plate slidably arranged inside the sliding frame, a mounting block rotatably arranged at the lower end of the sliding plate via a rotating column, a perforated barrel slidably arranged inside the mounting block, a moving drive mechanism for driving the perforated barrel to move into the drying box arranged inside the slide rail, a second motor arranged at the upper end of the sliding plate, the output shaft of the second motor being connected to the upper end of the rotating column via a coupling, a first lead screw rotatably arranged inside the sliding frame, the sliding plate being threadedly connected to the first lead screw, a first motor arranged at the upper end of the sliding frame, the output shaft of the first motor being connected to the upper end of the first lead screw via a coupling. The moving drive mechanism includes a second lead screw that is rotatably installed inside the slide rail, a slide rail frame that is threadedly connected to the second lead screw, a third motor that is installed on the rear side of the slide rail frame, and the output shaft of the third motor that is connected to the rear end of the second lead screw via a coupling.

[0006] As a further improvement of this utility model, a support frame is provided between the lower ends of the ultrasonic cleaning box and the drying box, and the ultrasonic cleaning box and the drying box are fixed to the support frame by welding.

[0007] As a further improvement of this utility model, the lower end of the ultrasonic cleaning box is provided with a water outlet pipe 1, which is connected to the interior of the ultrasonic cleaning box. A solenoid valve 1 is connected in series in the middle of the water outlet pipe 1. The lower end of the drying box is provided with a water outlet pipe 2, which is connected to the interior of the ultrasonic cleaning box. A solenoid valve 2 is connected in series in the middle of the water outlet pipe 2.

[0008] As a further improvement of this utility model, a screw is threaded into the internal threaded hole at the upper end of the mounting block and the drain hole barrel. A knob is provided on the right side of the screw, and the screw and the knob are fixed by welding.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by controlling the operation of motor one, motor three, and motor two, the cleaned fasteners are moved into the drying chamber for centrifugal drying. Then, by controlling the operation of the heating rod, the aerospace fasteners inside the perforated barrel are heated and dried. The cleaned aerospace fasteners can be automatically moved into the drying mechanism, centrifuged and dried, and then heated and dried without waiting for manual transfer, which greatly improves cleaning efficiency.

[0011] Secondly, by supporting the lower end of the drain barrel with one hand and rotating the knob counterclockwise with the other hand, the screw can be removed from the mounting block, releasing the drain barrel from its fixation. This facilitates the quick unloading of aerospace fasteners after the drain barrel has been cleaned.

[0012] Thirdly, by controlling the opening of solenoid valve one, the wastewater after ultrasonic cleaning can be quickly discharged through water outlet pipe one, making it convenient for personnel to quickly replace the contaminated water inside. Also, by controlling the opening of solenoid valve two, the water spun out by centrifugation can be quickly discharged through water outlet pipe two, making it convenient for personnel to treat the wastewater inside.

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, an ultrasonic cleaning device for aerospace fasteners includes an ultrasonic cleaning chamber 101. A drying chamber 201 is arranged on the left side of the ultrasonic cleaning chamber 101. Multiple heating rods 202 are respectively arranged on the left and right sides of the inner wall of the drying chamber 201. A slide rail 113 is arranged between the rear side of the ultrasonic cleaning chamber 101 and the drying chamber 201. A sliding frame 111 is slidably arranged inside the slide rail 113. A sliding plate 103 is slidably arranged inside the sliding frame 111. A mounting block 108 is rotatably arranged at the lower end of the sliding plate 103 via a rotating column. The ultrasonic cleaning box 108 has a sliding perforated barrel 105 inside. The slide rail 113 has a moving drive mechanism inside to move the perforated barrel 105 into the drying box 201. The mounting block 108 and the perforated barrel 105 are internally threadedly connected to a screw 109 through an internally threaded hole at the upper end. A knob 110 is provided on the right side of the screw 109. A support frame 116 is provided between the lower ends of the ultrasonic cleaning box 101 and the drying box 201.

The moving drive mechanism includes a second lead screw 114 rotatably provided inside the slide rail 113. The slide rail frame is threadedly connected to the second lead screw 114. A third motor 115 is provided at the rear side of the slide rail frame. The output shaft of the third motor 115 is connected to the rear end of the second lead screw 114 through a coupling.

[0022] By injecting water into the ultrasonic cleaning chamber 101, and then placing the aerospace fasteners to be cleaned inside the perforated barrel 105, the ultrasonic cleaning chamber 101 is then turned on and started. Through cavitation, dirt and other impurities attached to the surface of the aerospace fasteners can be effectively removed.

[0023] After cleaning, the motor 102 is turned on, and the output shaft drives the lead screw 112 to rotate, which in turn moves the perforated barrel 105 on the sliding plate 103 and the aerospace fasteners inside it upward out of the ultrasonic cleaning box 101. Then the motor 102 is turned off. Next, the motor 315 is turned on, and the output shaft drives the lead screw 114 to rotate, which moves the perforated barrel 105 on the slide frame to the upper end of the drying box 201. Then the motor 315 is turned off. Then the motor 102 is turned on, and the aerospace fasteners inside the perforated barrel 105 are moved downward into the drying box 201. Then the motor 102 is turned off. At the same time, the motor 2104 is turned on, and the output shaft drives the perforated barrel 105 at the lower end of the mounting block 108 to rotate, centrifugally drying the aerospace fasteners inside. Finally, the heating rod 202 is turned on to heat and dry the aerospace fasteners inside the perforated barrel 105.

[0024] After cleaning, heating and drying, the motor 102 is turned on to move the aerospace fasteners inside the perforated barrel 105 upwards and away from the interior of the drying chamber 201. Then, one hand holds the lower end of the perforated barrel 105, and the other hand rotates the knob 110 counterclockwise to remove the screw 109 from the mounting block 108, thus releasing the fixation of the perforated barrel 105 and allowing for the rapid unloading of the aerospace fasteners after the internal cleaning is completed.
