Description

Technical Field

[0001] The utility model belongs to the technical field of automobile processing, in particular to an air blowing device for a CNC product hole. Background Art

[0002] In industries such as automotive manufacturing and electronic equipment production, the processing and manufacturing of workpieces such as car screen brackets and connectors often involves the machining of small-diameter deep holes or threaded holes. During the machining of these holes, especially when operated by CNC (computer numerical control) machine tools, a large amount of internal debris is easily generated. This debris often remains in the hole. Especially when machining threaded holes, the structure of the thread makes it easy for debris to get stuck between the threads, making it difficult to remove by conventional methods. The remaining debris not only affects the finish of the surface inside the hole, but may also affect the subsequent assembly process, resulting in poor assembly and even the overall performance and life of the workpiece. In addition, cutting fluids or other lubricants may be used during the machining process. These fluids will mix with the debris, forming oil stains that further increase the difficulty of cleaning.

[0003] In the existing technology, simple mechanical treatment methods are usually used to clean debris from these small-diameter deep holes or thread holes, such as using brushes, air guns, or hand tools. However, these methods have significant shortcomings. First, mechanical treatment methods often cannot penetrate deep into the bottom of the hole or the depth of the thread, resulting in incomplete cleaning and residual debris. Mechanical cleaning can easily cause secondary damage to the inner surface of the hole, especially when processing precision workpieces, which may affect the quality of the inner surface of the hole and thus the overall quality of the product. Finally, the debris and oil generated during the mechanical cleaning process are easily scattered, increasing the risk of pollution in the operating environment. It also poses certain safety hazards. The operator may be injured by the flying debris. Utility Model Content

[0004] The purpose of the present invention is to provide an air blowing device for CNC product holes to solve at least one aspect of the problems and defects raised in the above background technology.

[0005] Provided is a blowing device for CNC product holes, comprising a ventilation pipeline, one side of the ventilation pipeline is fixedly connected to an air guide pipe, one end of the air guide pipe is connected to an air guide connecting seat, the end of the air guide connecting seat away from the air guide pipe is fixedly connected to an air cylinder, a blowing mechanism is provided in the air cylinder, and a protective cover is provided on the outside of the air cylinder.

[0006] Furthermore, the ventilation pipe is a spiral connecting pipe. The spiral structure of the spiral connecting pipe gives it a certain flexibility, which prevents the ventilation pipe from breaking or loosening due to vibration. In addition, the spiral pipe can absorb part of the vibration and reduce the impact on the entire device; the spiral structure can guide the airflow to a certain extent, making it smoother when passing through the air guide pipe, reducing turbulence and pressure loss, thereby improving the air guide efficiency. When the gas flows along the inner wall of the spiral pipe, the friction and pressure distribution are more even, which helps to maintain the stability and flow rate of the airflow.

[0007] Furthermore, the gas pipe is threadedly connected to the gas connecting seat, which ensures the stability and safety of the gas transmission process, provides good sealing, and prevents high-pressure gas from leaking between the gas pipe and the gas connecting seat. By applying appropriate tightening force at the threaded joint, the gas is effectively sealed inside the pipeline system, maintaining the safety of the gas system.

[0008] Furthermore, an air guide channel is provided in the air guide connecting seat, an air guide pipe is provided on one side of the air guide channel, and an air blow cylinder is provided on the side of the air guide channel away from the air guide pipe. The connection between the air guide connecting seat and the air blow channel constitutes an entrance for gas to enter the air blow cylinder from the air guide pipe, reducing the resistance and pressure loss in the gas flow to prevent gas leakage. The air blow channel is connected to the blowing mechanism on the side away from the air guide connecting seat. The high-pressure gas transported through the air blow channel will be further accelerated or concentrated when entering the blowing mechanism 5 to form a strong airflow, which can effectively remove debris and oil in the tooth hole.

[0009] Furthermore, an air blowing channel is provided inside the air barrel, an air guide connecting seat is provided on one side of the air blowing channel, a blowing mechanism is provided on the side of the air blowing channel away from the air blowing channel, and a blowing mechanism is provided on the side of the air blowing channel away from the air barrel. The air blowing channel stably transmits the high-pressure gas from the air guide pipe to the air blowing mechanism. The connection between the air guide connecting seat and the air blowing channel constitutes an entrance for the gas to enter the air barrel from the air guide pipe, avoiding unnecessary fluctuations in the air flow during the conduction process. The air channel is connected to the blowing mechanism on the side away from the air guide connecting seat. The high-pressure gas transported through the air channel will be further accelerated or concentrated when entering the blowing mechanism to form a strong airflow, which can effectively remove debris and oil in the tooth hole.

[0010] Furthermore, the blowing mechanism includes a blowing seat, the mounting tube is threadedly connected in the mounting tube, a blowing needle is provided below the mounting tube, and a blowing hole is provided below the blowing needle. When the gas passes through the blowing needle and reaches the blowing hole, the airflow is concentrated and accelerated to form a strong airflow column, which is directly sprayed into the hole to be cleaned through the blowing hole, and can efficiently blow away the debris and oil in the hole to achieve a cleaning effect.

[0011] Furthermore, an oil-absorbing cotton layer is provided inside the protective cover body. The oil-absorbing cotton layer is provided inside the protective cover body, which can effectively absorb and capture oil. The oil-absorbing cotton is a special material with strong adsorption capacity, which can quickly absorb overflowed oil and prevent it from leaking.

[0012] Furthermore, a compression nut is provided on the outside of the connection between the air duct and the air duct connecting seat. When the compression nut is tightened, it applies pressure to the contact surface between the air duct and the air duct connecting seat, compressing the sealing material at the interface to prevent gas leakage under high pressure conditions.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Connect external equipment through the ventilation pipe to allow high-pressure gas to flow into the system. One end of the ventilation pipe is fixedly connected to the air guide pipe. The high-pressure gas is transported to the air guide connection seat through the air guide pipe and then introduced into the air blower. After the high-pressure gas enters the air blower, the blowing mechanism will concentrate and accelerate the airflow, and clean the debris and oil in the hole by spraying. By blowing with high-pressure gas, it can penetrate into the bottom of the tooth hole or the deep of the thread, and can effectively remove the residue in the tooth hole to ensure the processing quality. The setting of the protective cover can prevent the debris and oil generated during the mechanical cleaning process from flying easily, thereby protecting the safety of the operator.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-2After the air is exhausted, the air in the air filter 4 is cooled and the air in the air filter 4 is cooled, and the air in the air filter 4 is in a state of being blown out of the air filter 4. As shown in FIG1 , in the embodiment of the present invention, a device for blowing air in the hole of CNC product comprises a ventilation pipe 1, one side of the ventilation pipe 1 is fixedly connected to the air guide pipe 2, one end of the air guide pipe 2 is connected to the air guide connecting seat 3, and the end of the air guide connecting seat 3 away from the air guide pipe 2 is fixedly connected to the blowing cylinder 4. A blowing mechanism 5 is arranged in the blowing cylinder 4, and a protective cover body 6 is sleeved on the outside of the blowing cylinder 4. The external equipment is connected through the ventilation pipe 1 to allow high-pressure gas to flow into the system, one end of the ventilation pipe 1 is fixedly connected to the air guide pipe 2, and the high-pressure gas is transported to the air guide connecting seat 3 through the air guide pipe 2 and then introduced into the blowing cylinder 4. After the high-pressure gas enters the blowing cylinder 4, the blowing mechanism 5 will concentrate and accelerate the airflow, and clean the debris and oil in the hole by spraying. By blowing with high-pressure gas, it can penetrate into the bottom of the hole or the depth of the thread, and can effectively remove the residue in the hole, ensuring the processing quality. The setting of the protective cover body 6 can prevent the debris and oil generated during the mechanical cleaning process from flying easily, thereby protecting the safety of the operator.

[0026] In one embodiment, see Figure 1 and Figure 2 As shown, the ventilation pipe 1 is a spiral connecting pipe. The spiral structure of the spiral connecting pipe makes it flexible to a certain extent, which prevents the ventilation pipe 1 from breaking or loosening due to vibration. In addition, the spiral pipe can absorb part of the vibration and reduce the impact on the entire device; the spiral structure can guide the airflow to a certain extent, making it smoother when passing through the air guide pipe 2, reducing turbulence and pressure loss, thereby improving the air guide efficiency. When the gas flows along the inner wall of the spiral pipe, the friction and pressure distribution are more even, which helps to maintain the stability and flow rate of the airflow.

[0027] In one embodiment, see Figure 1 and Figure 2 As shown, the air guide tube 2 is threadedly connected to the air guide connecting seat 3. The air guide tube 2 is firmly fixed to the gas guide connecting seat 3 by rotating the thread to ensure that the two will not loosen or detach due to vibration or pressure changes, thereby ensuring the stability and safety of the gas transmission process, providing good sealing, and avoiding leakage of high-pressure gas between the air guide tube 2 and the gas guide connecting seat 3. By applying appropriate tightening force at the threaded joint, the gas is effectively sealed inside the pipeline system, maintaining the safety of the gas guide system.

[0028] In one embodiment, see Figure 1 and Figure 2As shown, an air guide channel 31 is provided in the air guide connecting seat 3, an air guide pipe 2 is provided on one side of the air guide channel 31, and an air cylinder 4 is provided on the side of the air guide channel 31 away from the air guide pipe 2. The air guide channel 31 is used to smoothly guide the high-pressure gas entering from the air guide pipe 2 into the air cylinder 4, ensuring the smoothness and stability of the gas flow. The air guide pipe 2 is connected to one end of the air guide channel 31, forming an initial path for the gas to enter the system from the external high-pressure source. After the high-pressure gas transmitted by the air guide pipe 2 enters the air guide channel 31, it is transmitted to the air cylinder 4 through the air guide channel 31. The airflow is conducted to the air cylinder 4, and then transmitted to the blowing mechanism 5 by the air cylinder 4, thereby maintaining the energy of the gas to the greatest extent and improving the effect of the blowing operation.

[0029] In one embodiment, see Figure 1 and Figure 2 As shown, an air blowing channel 41 is provided inside the air blowing tube 4, an air guide connecting seat 3 is provided on one side of the air blowing channel 41, and an air blowing mechanism 5 is provided on the side of the air blowing channel 41 away from the air blowing channel 41. The air blowing channel 41 stably transmits the high-pressure gas from the air guide pipe 2 to the air blowing mechanism 5. The connection between the air guide connecting seat 3 and the air blowing channel 41 constitutes an entrance for the gas to enter the air blowing tube 4 from the air guide pipe 2, avoiding unnecessary fluctuations in the air flow during the conduction process. The air blowing channel 41 is connected to the air blowing mechanism 5 on the side away from the air guide connecting seat 3. The high-pressure gas transported through the air blowing channel 41 will be further accelerated or concentrated when entering the air blowing mechanism 5 to form a strong airflow, which can effectively remove debris and oil in the tooth hole.

[0030] In one embodiment, see Figure 1 and Figure 2As shown, the blowing mechanism 5 includes a blowing seat 51, which is threadedly connected to the mounting tube 52. A blowing needle 53 is provided below the blowing seat 51, and a blowing hole 531 is provided below the blowing needle 53. During operation, the gas enters the blowing tube 4 through the blowing channel 41 and is conducted to the blowing seat 51 through the threaded connection. The tightness of the threaded connection can adjust the flow rate of the gas to ensure that the gas can enter the blowing seat 51 with a suitable pressure. The function of the blowing needle 53 is that the gas enters the blowing needle 53 after passing through the blowing seat 51. The narrow channel in the blowing needle 53 will pressurize the gas, thereby forming a high-speed airflow. The high-speed airflow flows out from the inside of the blowing needle 53, which will be able to effectively blow away the debris and oil in the hole. The air flow is concentrated and accelerated to form a strong air flow column, which is directly ejected into the hole to be cleaned through the air hole 531, and can effectively blow away the debris and oil in the hole. The external high-pressure gas enters the mounting cylinder 52 through the air guide tube 2 and the air guide connecting seat 3, and then enters the air blowing seat 51 through a threaded connection. The gas is further pressurized and guided when entering the air blowing needle 53, forming a high-speed air flow. The high-speed air flow ejected through the air hole 531 acts on the debris and oil in the hole with high impact force, quickly blowing them out of the hole, thereby achieving a cleaning effect.

[0031] In one embodiment, see Figure 1 and Figure 2 As shown, the protective cover 6 is provided with an oil-absorbing cotton layer, which can effectively absorb and capture oil. The oil-absorbing cotton is a special material with strong adsorption capacity, which can quickly absorb spilled oil and prevent it from leaking. When oil splashes into the protective cover 6 during the blowing operation, the oil-absorbing cotton layer will quickly absorb the oil and lock it inside the fibers, preventing it from flowing out or penetrating into the external environment.

[0032] In one embodiment, see Figure 1 and Figure 2 As shown, a compression nut 7 is further provided on the outside of the connection between the air duct 2 and the air duct connecting seat 3. When the compression nut 7 is tightened, it applies pressure to the contact surface between the air duct 2 and the air duct connecting seat 3, compressing the sealing material at the interface (such as an O-ring or a sealing gasket). During the compression process, the sealing material fills the tiny gap at the connection, thereby forming an effective seal to prevent gas leakage under high pressure conditions.

[0033] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
