Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to an air blowing device and processing equipment. Background Art
[0002] When a machine tool uses a tool to process a workpiece, it generates a large amount of debris. The debris will adhere to the surface of the machine tool's spindle. When replacing the tool, the debris can easily enter the interior of the spindle, affecting the replacement and assembly of the tool, and thus affecting the processing quality of the tool. Due to the limited installation space within the machine tool, a blowing mechanism is usually not provided. A robot is required to drive the blow pipe to continuously adjust the blowing angle so that the blow pipe blows toward the spindle to remove the debris adhered to the surface of the spindle. However, the cost of using a robot is high, and the blowing angle of the blow piece needs to be constantly adjusted, resulting in a long operation cycle and low cleaning efficiency.

For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection, an electrical connection, or mutual communication; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two elements or an interaction between two elements. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0041] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0042] See also Figure 1An embodiment of the present application provides a processing device 100, which includes a processing spindle 101 and a blowing device 102. The processing spindle 101 is used to connect a tool to process a workpiece. The blowing device 102 is connected to the processing spindle 101 and is used to form a vortex to blow toward the processing spindle 101 to remove debris adhered to the processing spindle 101, thereby improving cleaning efficiency at a low cost.
[0043] See also Figure 1 、 Figure 2 and Figure 3 The air blowing device 102 includes a connecting assembly 10, a fixing assembly 20, and an air blowing assembly 30. The connecting assembly 10 includes a connecting piece 11 and a plurality of air delivery pieces 12. The plurality of air delivery pieces 12 are respectively connected to the connecting piece 11. The connecting piece 11 is used to connect to an external air source to deliver air provided by the external air source to the plurality of air delivery pieces 12. The fixing assembly 20 is provided on one side of the connecting piece 11 and is used to connect to the processing spindle 101. A plurality of blowing assemblies 30 are arranged at intervals around the circumference of the machining spindle 101 on the fixed assembly 20 and are arranged one-to-one with a plurality of gas delivery members 12. Each blowing assembly 30 includes a connecting member 31, an outer cylinder member 32, an inner cylinder member 33 and a hose member 34. The connecting member 31 is passed through the fixed assembly 20 and connected to the corresponding gas delivery member 12. The outer cylinder member 32 is connected to the connecting member 31. The inner cylinder member 33 is provided with a tapered groove 331 and is rotatably connected to the outer cylinder member 32. The hose member 34 is passed through the tapered groove 331 and the outer cylinder member 32 and is connected to the connecting member 31. The hose member 34, the connecting member 31 and the corresponding gas delivery member 12 are connected in sequence. The end of the hose member 34 away from the connecting member 31 rotates in the tapered groove 331 under the drive of the gas, and drives the inner cylinder member 33 to rotate relative to the outer cylinder member 32, so that the gas forms a vortex at the end of the inner cylinder member 33 away from the connecting member 31 and is blown toward the machining spindle 101.
[0044] When the above-mentioned processing equipment 100 and blowing device 102 are in operation, the external gas source delivers gas to multiple gas transmission parts 12 through the connecting part 11, and then the hose part 34 rotates in the inner cylinder part 33 under the drive of the gas, and drives the inner cylinder part 33 to rotate relative to the outer cylinder part 32, so that the gas forms a vortex at the end of the inner cylinder part 33 away from the connecting part 31 and blows toward the processing spindle 101. The gas forming the vortex rotates on the surface of the processing spindle 101, thereby increasing the contact area between the gas and the processing spindle 101, and there is no need to use a complex mechanical structure for cleaning operations, thereby improving the cleaning efficiency at a low cost.
[0045] In addition, the groove area of the conical groove 331 gradually increases along the direction of the connecting member 31 pointing to the outer cylinder member 32, so that the vortex formed by the gas also increases under the restriction of the conical groove 331, thereby increasing the contact area between the gas and the processing spindle 101, thereby improving the cleaning efficiency.
[0046] Specifically, the number of the aforementioned blowing assemblies 30 is "plural," meaning two or more. It should be noted that while debris adhering to the lower surface of the machining spindle 101 can be directly separated from the machining spindle 101 by its own gravity, debris adhering to the upper surface of the machining spindle 101 cannot be separated from the machining spindle 101 by its own gravity. Therefore, in this embodiment, multiple sets of blowing assemblies 30 are provided corresponding to the upper surface of the machining spindle 101.
[0047] See also Figure 3 and Figure 4 In some embodiments, the outer cylinder 32 includes an outer cylinder 321 and a bearing body 322. The outer cylinder 321 is connected to the connecting member 31 and is provided with a tapered hole 3212 and a seating hole 3211 in sequence along the direction from the connecting member 31 to the outer cylinder 321. The two ends of the seating hole 3211 are respectively connected to the tapered hole 3212 and the connecting member 31. The connecting member 31 is inserted into the end of the seating hole 3211 away from the tapered hole 3212 and is threadedly connected to the outer cylinder 321. The tapered hole 3212 receives the inner cylinder 33. The bearing body 322 is embedded in the end of the seating hole 3211 adjacent to the tapered hole 3212 and is sleeved on the inner cylinder 33. For example, the bearing body 322 may be a rolling bearing.
[0048] In this way, by sleeved on the inner cylinder part 33, the inner cylinder part 33 and the outer cylinder body 321 can be separated, and the inner cylinder part 33 can rotate relative to the outer cylinder body 321, avoiding excessive friction caused by direct contact between the inner cylinder part 33 and the outer cylinder body 321, which makes it impossible for the inner cylinder part 33 to rotate stably, which is conducive to achieving stable rotation of the inner cylinder part 33 relative to the outer cylinder body 321, so as to cooperate with the rotation of the hose part 34 in the inner cylinder part 33 to convert the gas into a vortex.
[0049] See also Figure 3 and Figure 4 In some embodiments, the inner cylindrical member 33 includes a retaining body 332 and an inner cylindrical member 333. The retaining body 332 is disposed through the bearing body 322 and is engaged therewith. The retaining body 332 defines a receiving hole 3321. The inner cylindrical member 333 is disposed within the tapered hole 3212 and is connected to the retaining body 332. The inner cylindrical member 333 defines a tapered groove 331, which communicates with the receiving hole 3321 to receive the hose member 34.
[0050] In this way, the tapered groove 331 is connected to the receiving hole 3321 to form a receiving channel for the hose 34 , so that the hose 34 and the inner tube 33 are arranged reasonably and interference between the hose 34 and the inner tube 33 is avoided.
[0051] See also Figure 4In some embodiments, the radial cross-sectional area of the receiving hole 3321 along the clamping body 332 is larger than the radial cross-sectional area of the hose 34 along the clamping body 332, so that the receiving hole 3321 can provide a sufficiently large activity space for the hose 34, so that the hose 34 can rotate stably in the conical groove 331 under the action of gas, and avoid the aperture of the receiving hole 3321 being too small to affect the rotation of the hose 34.
[0052] Please continue reading Figure 4 In some embodiments, the connection between the receiving hole 3321 and the tapered groove 331 is an arc-shaped structure 3311, which can avoid the generation of large friction between the hose part 34 and the inner cylinder part 33 and damage to the hose part 34, which is beneficial to improving the service life of the hose part 34.
[0053] See also Figure 3 and Figure 4 In some embodiments, the hose 34 includes a tube body 341, a first protective body 342, and a second protective body 343. The tube body 341 is movably disposed through the receiving hole 3321 and the placement hole 3211 and is connected to the connector 31. The tube body 341 communicates with the connector 31 and extends to the tapered groove 331. The first protective body 342 is sleeved on the tube body 341 and located at the junction of the tapered groove 331 and the receiving hole 3321. The second protective body 343 is sleeved on the end of the tube body 341 away from the connector 31.
[0054] In this way, by arranging the first protective body 342 and the second protective body 343 to be respectively sleeved on different positions of the tube body 341, the tube body 341 can collide with the inner cylinder part 33 through the first protective body 342 and the second protective body 343 during the rotation process, thereby avoiding expansion and damage between the tube body 341 and the inner cylinder part 33, and further improving the service life of the hose part 34.
[0055] The hardness of the first protective body 342 and the second protective body 343 is greater than the hardness of the tube body 341 , so that the first protective body 342 and the second protective body 343 can effectively protect the tube body 341 .
[0056] See also Figure 1 and Figure 5 In some embodiments, the fixing assembly 20 includes a fixing member 21 and a protective member 22. The fixing member 21 is configured to be detachably connected to the machining spindle 101. The protective member 22 covers the machining spindle 101 and the plurality of outer cylinder members 32 and is connected to the fixing member 21.
[0057] In this way, by providing a detachable connection between the fixing part 21 and the machining spindle 101, it is convenient for the operator to assemble the blowing device 102 to the machining spindle 101. In addition, by providing a protective part 22 covering the machining spindle 101 and multiple outer cylinder parts 32, it is possible to prevent the debris generated by the tool connected to the machining spindle 101 from splashing everywhere, which is conducive to centralized processing of the debris and improves cleaning efficiency.
[0058] See also Figure 5 In some embodiments, the fixing member 21 includes an arcuate fixing body 211 and a locking body 212. The arcuate fixing body 211 is used to be sleeved on the processing spindle 101, with the two ends of the arcuate fixing body 211 abutting each other. The locking body 212 is inserted through one end of the arcuate fixing body 211 and is threadedly connected to the other end of the arcuate fixing body 211. For example, the locking body 212 can be a bolt.
[0059] In this way, by setting a locking body 212 that passes through one end of the arc-shaped fixed body 211 and is threadedly connected to the other end of the arc-shaped fixed body 211, a split structure can be formed between the fixing member 21 and the processing spindle 101, thereby realizing a detachable connection between the fixing member 21 and the processing spindle 101.
[0060] Please continue reading Figure 5 In some embodiments, the protective member 22 is provided with an arcuate surface 221 on the side facing the outer cylinder member 32. After the hose member 34 blows away the debris adhered to the upper surface of the machining spindle 101, part of the debris slides down to a preset position under the guidance of the arcuate surface 221, making it easier to collect the blown debris.
[0061] The working process of the above-mentioned processing equipment 100 is roughly as follows:
[0062] First, the machining spindle 101 drives the tool to machine the workpiece and generates chips, which adhere to the upper surface of the machining spindle 101;
[0063] Then, the external gas source delivers the gas to the plurality of gas delivery members 12 through the connecting member 11, so that each gas delivery member 12 delivers the gas to the corresponding connecting member 31;
[0064] Finally, the connecting piece 31 delivers the gas to the hose piece 34, so that the hose piece 34 rotates in the inner cylinder piece 33 under the drive of the gas, and drives the inner cylinder piece 33 to rotate relative to the outer cylinder piece 32, so that the gas forms a vortex at the end of the inner cylinder piece 33 away from the connecting piece 31 and blows toward the processing spindle 101. The gas forming the vortex rotates on the surface of the processing spindle 101, thereby increasing the contact area between the gas and the processing spindle 101, and there is no need to use a complex mechanical structure for cleaning operations, thereby improving the cleaning efficiency at a low cost.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
