Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a snap-fit ​​fixing device for air compressor bearings. Background Technology

[0002] An air compressor is a device that converts the mechanical energy of a prime mover into the pressure energy of a gas. The working principle of an air compressor is essentially to reduce the volume of gas through mechanical movement, thereby reducing the intermolecular distance and increasing the internal energy, thus increasing the air pressure. Ultimately, it provides power or air source for pneumatic equipment and processes. It is widely used in industrial production, medical, energy and other fields, and is the core power equipment for driving pneumatic equipment, such as pneumatic tools and automation components.

[0003] Traditional clamp-on fixing devices for air compressors have inherent defects in their elastic connection. Traditional clamps are mostly metal retaining rings (such as elastic retaining rings or C-rings) or bolt locking structures, relying on mechanical friction to fix the bearings. However, the high-frequency vibration of the crankshaft / rotor during air compressor operation can cause fatigue deformation of the clamps, leading to a decrease in preload. Traditional fixing devices pose safety hazards: if the clamps fail, the bearings may move axially, rubbing against the crankshaft and rotor, generating metal debris that can clog lubrication lines and cause accidents. Furthermore, the dust generated by the air compressor is not filtered, causing systemic harm to equipment operation, production safety, product quality, and environmental health. The lack of a filtration system in the air compressor can lead to multiple serious problems. Consequences: Dust entering the equipment will accelerate the wear of core components such as cylinders, rotors, and bearings, deteriorate the quality of compressed air, and cause pneumatic system blockage and reduced precision of components due to excessive dust content. In industries such as food and electronics, it can directly contaminate products, leading to excessive microbial levels in food, short circuits in semiconductor chips, and a significant reduction in yield. In addition, there are significant safety hazards, as combustible dust can cause internal deflagration and pipeline explosions, and dust accumulation in the electrical system can easily cause short circuits. Maintenance costs will also surge, with increased repair frequency and shorter replacement cycles. At the same time, component wear leads to reduced energy efficiency and serious energy waste. Unfiltered high-concentration dust-laden exhaust will also cause air pollution and harm the health of workers. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a clamping and fixing device for an air compressor bearing, including a body 1. A bearing clamping mechanism 2 is installed inside the body 1 for fixing inside the body 1. A cleaning mechanism 3 is installed at the right end of the body 1 for handling dust generated by the body 1 during long-term operation. The clamping mechanism 2 includes a U-shaped clamp 203. A trapezoidal groove 205 is installed at the lower end of the U-shaped clamp 203. An elastic pad 202 is provided on the inner side of the U-shaped clamp 203. A columnar bearing 204 is installed on the outer side of the U-shaped clamp 203. A semi-column wedge 201 is fixedly connected to the upper end of the elastic pad 202. A bolt 206 is threadedly connected to the semi-column wedge 201. A gas valve 8 is installed on the right side of the body 1. The left side of the gas valve 8 is connected to a pneumatic cylinder 13.

[0030] Specifically, when the machine body 1 is started, the bearing bush will rotate with the shaft. The buckle on the bearing bush is prone to loosening. The buckle mechanism 2 connects the elastic washer 202 and the semi-cylindrical wedge 201 with bolts 206 to fix the U-shaped buckle 203 on the cylindrical bearing bush 204. When the buckle mechanism 2 is used to fix the air compressor bearing bush, the trapezoidal groove at the bottom is used to tightly engage with the buckle, which enhances the fixing reliability of the buckle, automatically adapts to vibration and impact, and ensures the stable operation of the bearing bush. When the buckle mechanism 2 is used to fix the air compressor bearing bush, the elastic washer 202 inside is used to effectively buffer the vibration and impact that occurs during the operation of the equipment, reduce the friction and wear between the bearing bush and the buckle, and prevent the buckle from loosening or the bearing bush from shifting due to vibration.

[0031] Reference Figure 1 , Figure 4 and Figure 5 The upper part of the machine body 1 is equipped with a compressor main unit 4. A hinge 10 is installed on the front side of the compressor main unit 4. A door latch 11 is rotatably connected to the left side of the hinge 10. The cleaning mechanism 3 includes a cover plate 306. A screw 7 is threadedly connected to the front side of the cover plate 306. A slot 304 is installed on the top right side of the cleaning mechanism 3. A filter screen 305 is installed inside the slot 304. A slide groove 303 is installed on the rear side of the filter screen 305. A brush 302 is installed on the front side of the filter screen 305. An electric push rod 301 is installed on the left end of the brush 302. The cover plate 306 is installed on the front side of the brush 302.

[0032] Specifically, during the long-term operation of the machine body 1, the dust generated by the emissions cannot be treated. The filter screen 305 inside the cleaning mechanism 3 is cleaned by the brush 302. The left end of the brush 302 is fixedly connected by the electric push rod 301. The electric push rod 301 effectively cleans the area around the filter screen 305 by rotating. The cleaned dust is prevented from entering through the slot 304. During the filtration process, the filter screen 305 is used continuously. If it is not replaced in time, it will also cause improper cleaning. The slide 303 can replace the filter screen 305. When the internal components of the cleaning mechanism 3 have problems during operation, the cover plate 306 at the front end of the cleaning mechanism 3 is fixed by the screws 7, which facilitates the disassembly of the device and will effectively solve the problem of the internal components of the cleaning mechanism 3.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The upper end of the machine body 1 is equipped with a compressor host 4, the right end of the compressor host 4 is equipped with a gas control device 5, the front side of the gas control device 5 is equipped with a display 12, and the lower end of the machine body 1 is equipped with a base 6, the bottom of the base 6 is fixedly connected to a support rod 9.

[0034] Specifically, a compressor main unit 4 is installed at the upper end of the machine body 1, a gas control device 5 is installed at the right end of the compressor main unit 4, a display 12 is installed on the front side of the gas control device 5, the display 12 can observe gas changes and set gas parameters, a gas valve 8 on the outside of the machine body 1 controls the air intake, compression and exhaust, a base 6 is installed at the lower end of the machine body 1, a support rod 9 is fixedly connected to the bottom of the base 6, and the support rod 9 provides support for the machine body 1 and the base 6.

[0035] Working principle: During air compressor operation, the bearing bushes on both sides of the U-shaped buckle 203 rotate with the air compressor shaft. The semi-cylindrical wedge 201 is in close contact with the mating surfaces of the cylindrical bearing bush 204 and the base 6. The arc-shaped surface of the wedge is in contact with the outer surface of the bearing bush. By applying external force, the wedge is wedged into the gap between the bearing bush and the base 6. The inclined surface of the wedge generates a lateral thrust, which makes the bearing bush tightly pressed into the mounting position. At this time, the friction between the wedge and the bearing bush and the mounting base, as well as the self-locking characteristic of the wedge, prevent the bearing bush from loosening. The display screen of the gas control device 5 12. By observing the displayed parameters, determine whether the machine body 1 is in a qualified and stable state; in addition, the gas valve 8 and the pneumatic cylinder 13 rely on the high-pressure compressed air provided by the air compressor as a power source. The air pressure drives the piston to realize the rapid opening, closing or adjustment of the valve, thereby accurately controlling the gas flow and direction; the stable air supply of the air compressor ensures that the pneumatic cylinder 13 is sensitive and responsive, reducing the intensity of manual operation and the error rate, while extending the service life of the pneumatic cylinder 13. The two work together to improve the automation level and operational reliability of the industrial pipeline system.

[0036] During long-term operation, the air compressor will generate dust. When the filter device is activated, the electric push rod 301 will push the brush 302 to clean the filter screen 305. The cleaned dust will automatically enter the slot 304, effectively preventing dust from flying to other places and harming the environment. The sliding groove 303 can push it, and the filter screen 305 can be replaced in time to achieve better cleaning effect. When there is a problem with dust handling or other problems with the internal components of the filter device, the external device can be easily disassembled to ensure that the dust generated by the machine body 1 is dealt with in a timely manner.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
