Description

Technical Field

[0001] This utility model relates to the field of speed reducer processing technology, specifically to an automated CNC machine tool for processing low-noise speed reducers. Background Technology

[0002] In the automated machining process of low-noise reducer housings, the drilling process generates a large amount of metal shavings and dust. If not cleaned in time, this will not only pollute the machining environment and affect equipment accuracy, but may also harm the health of operators. In the existing technology, to solve this problem, a vacuum cleaner is usually installed next to the machine tool. However, its control method is mostly to start and stop synchronously with the machine tool's main program—that is, the vacuum cleaner starts working as soon as the machine tool starts and does not turn off until the entire machining process is completed.

[0003] While this control method can achieve debris collection, in actual processing, drilling is only one part of the entire process (which also includes non-drilling stages such as workpiece positioning and tool movement). The continuous operation of the vacuum cleaner during non-drilling stages has no actual dust collection function and instead causes unnecessary energy consumption, failing to meet the production requirements for energy conservation and emission reduction. Furthermore, prolonged continuous operation increases wear and tear on the vacuum cleaner, shortens its lifespan, and increases equipment maintenance costs. Therefore, how to achieve precise, on-demand start and stop of the vacuum cleaner to reduce energy waste and extend equipment lifespan has become a pressing problem in existing technology. Therefore, improvements are needed. Utility Model Content

[0025] like Figures 1-5 The diagram illustrates an automated CNC machine tool for processing low-noise speed reducers according to one embodiment of the present invention. It includes a base 1, a machine tool 2 mounted above the base 1, a control board 3 on the front side of the machine tool 2, a linear module 5 bolted to the left side of the machine tool 2, a drilling mechanism 7 on the left side of the linear module 5, a movable plate 71 disposed on the left side of the linear module 5, a connecting plate 72 welded to the left side of the movable plate 71, a cylinder 74 welded below the connecting plate 72, and a circular plate 77 slidably mounted on the outer side of the cylinder 74. A first annular cylinder 78 and a third annular cylinder 712 are welded to the bottom of the circular plate 77. A second annular cylinder 79 is slidably installed between the inner side of the first annular cylinder 78 and the outer side of the third annular cylinder 712. A pressure sensor 713 is bolted to the lower side of the circular plate 77 and is located between the inner side of the first annular cylinder 78 and the outer side of the third annular cylinder 712. A telescopic spring 714 is provided between the lower side of the pressure sensor 713 and the upper side of the second annular cylinder 79. A vacuum cleaner 6 is bolted to the left side of the machine tool 2. The input end of the vacuum cleaner 6 extends through to the bottom of the circular plate 77.

[0026] The base 1 provides a supporting foundation, the machine tool 2 serves as the main body of the equipment to support all components, the control board 3 realizes overall control, the linear module 5 drives the drilling mechanism 7 to move and adjust its position, the components in the drilling mechanism 7 cooperate to realize the drilling action, the vacuum cleaner 6 is used to collect the debris generated during processing, and the pressure sensor 713 senses the pressure change to link the vacuum cleaner 6 to work.

[0027] By setting up a linkage structure between the pressure sensor 713, the telescopic spring 714 and the vacuum cleaner 6, when the second annular cylinder 79 contacts the workpiece or the base 1, the pressure signal triggers the vacuum cleaner 6 to start. After drilling is completed, it automatically shuts off as the pressure disappears, realizing the on-demand start and stop of the vacuum cleaner. This solves the energy waste problem caused by the continuous operation of the vacuum cleaner in the prior art and improves the energy efficiency of the equipment.

[0028] like Figures 1-5As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise reducers. A disassembly and assembly mechanism 8 is provided above the circular plate 77. The disassembly and assembly mechanism 8 includes a bottom ring block 81 welded to the top of the circular plate 77. A connecting block 82 is uniformly welded above the bottom ring block 81. An elastic clamping ring 83 is glued above the connecting block 82. An outer ring block 84 is welded to the outside of the bottom ring block 81. A threaded groove 85 is opened on the inner side of the top of the outer ring block 84. A threaded ring 86 is threadedly installed on the inner side of the threaded groove 85. A retaining ring 88 is welded below the threaded ring 86.

[0029] In some examples, the disassembly and assembly mechanism 8 is connected to the circular plate 77 via the bottom ring block 81. The rotating threaded ring 86 moves along the threaded groove 85, causing the retaining ring 88 to squeeze the elastic clamping ring 83. The force is transmitted through the connecting block 82 to achieve clamping and fixing of the component. The reverse operation can release the component to complete the replacement.

[0030] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise reducers. A servo motor 73 is bolted on the upper part of the connecting plate 72. A rotating shaft 75 is bolted vertically downward from the output end of the servo motor 73. The rotating shaft 75 extends through to the lower part of the cylinder 74 and a drill bit 76 is bolted on it.

[0031] In some examples, a servo motor 73 provides power to drive the drill bit 76 to rotate at high speed via a shaft 75, and a connecting plate 72 and a cylinder 74 provide mounting support for the above components to achieve drilling of the workpiece.

[0032] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise speed reducers, with a chuck 4 provided above the base 1 and the chuck 4 positioned below the drill bit 76.

[0033] In some examples, the chuck 4, supported by the base 1, is located directly below the drill bit 76 to fix the workpiece to be processed and ensure that the workpiece is in a stable position when the drill bit 76 is drilling.

[0034] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise reducers. A limiting groove 711 is opened on the inner side of the first annular cylinder 78, and a limiting ring 710 is welded to the upper end of the second annular cylinder 79. The limiting ring 710 is slidably connected inside the limiting groove 711, and a telescopic spring 714 is elastically installed between the upper side of the limiting ring 710 and the lower side of the pressure sensor 713.

[0035] In some examples, the limiting ring 710 slides along the limiting groove 711 to restrict the movement direction of the second annular cylinder 79, ensuring that the second annular cylinder 79 can only move relative to the first annular cylinder 78 in the vertical direction, thus ensuring the stability of the structural fit.

[0036] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise reducers. The two ends of the telescopic spring 714 are respectively set on the lower side of the pressure sensor 713 and the upper end of the limiting ring 710. When the telescopic spring 714 is in the released state, the limiting ring 710 is placed at the lower end of the limiting groove 711.

[0037] In some examples, the telescopic spring 714 provides elastic support between the pressure sensor 713 and the limiting ring 710. When no external force is applied, the limiting ring 710 is at the lowest end of the limiting groove 711. When an external force is applied, the telescopic spring 714 deforms, causing the limiting ring 710 to move upward and triggering the pressure sensor 713 to work. After the external force disappears, the telescopic spring 714 resets, causing the limiting ring 710 to return to its initial position.

[0038] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise reducers, with a knob 87 welded above the threaded ring 86, and the knob 87 is located on the upper side of the outer ring block 84.

[0039] In some examples, the knob 87 provides an operating fulcrum for the threaded ring 86, which can be moved along the threaded groove 85 on the outer ring block 84 by rotating the knob 87, thereby achieving tightness control of the component.

[0040] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise speed reducers. The cross-section of the retaining ring 88 is an inverted triangle, and the cross-section of the elastic clamping ring 83 is a right trapezoid. The inner inclined surface of the retaining ring 88 is in contact with the outer inclined surface of the elastic clamping ring 83.

[0041] In some examples, the retaining ring 88 and the elastic clamping ring 83 are fitted together by an inclined surface. When the retaining ring 88 moves down, the radial extrusion force is generated by the inclined surface contact, which causes the elastic clamping ring 83 to deform and clamp the component. The inclined surface fit ensures stable force transmission.

[0042] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise reducers. The chuck 4 is located above the base 1 and directly below the drill bit 76 in the drilling mechanism 7. The central axis of the chuck 4 is collinear with the central axis of the drill bit 76.

[0043] In some examples, the chuck 4 and the drill bit 76 are coaxial and correspond vertically, ensuring that the drill bit 76 can accurately act on the preset position of the workpiece fixed by the chuck 4 when rotating to drill, thereby improving the machining accuracy.

[0044] like Figures 1-5 As shown, on the other hand, this utility model also provides an automated CNC machine tool for processing low-noise reducers. The input end of the vacuum cleaner 6 is located below the circular plate 77 and faces the outside of the drill bit 76. The main body of the vacuum cleaner 6 is fixed to the left side of the machine tool 2.

[0045] In some examples, the input end of the vacuum cleaner 6 is close to the processing area of ​​the drill bit 76, which can efficiently collect the debris generated when the drill bit 76 is drilling. The main body is fixed on the machine tool 2 to ensure stable position and realize directional dust collection function.

[0046] Working principle and usage process of this utility model: Fix the gearbox housing to be processed onto the chuck 4 above the base 1, and clamp the workpiece with the chuck 4 to ensure stability and prevent shaking during processing; check whether the parameters of the control board 3 are normal, and confirm the initial position of the drilling mechanism 7 and the specification of the drill bit 76 according to the model of the gearbox housing and the drilling requirements; replace the second annular cylinder 79 with the corresponding specification. If different models of gearbox housings need to be processed, the second annular cylinder 79 of the appropriate size needs to be replaced; rotate the knob 87 of the disassembly and assembly mechanism 8 to drive the threaded ring 86 along the threaded groove 85 of the outer ring block 84 towards Screw it up to disengage the retaining ring 88 from the outer bevel of the elastic clamping ring 83; after the elastic clamping ring 83 loses its compression, it returns to its original shape, releasing its clamping on the cylinder 74, and the new second annular cylinder 79 is taken out. Insert the corresponding bottom ring block 81 into the outside of the cylinder 74, and rotate the knob 87 in the opposite direction to make the threaded ring 86 drive the retaining ring 88 to screw downward. The inner bevel of the retaining ring 88 presses against the outer bevel of the elastic clamping ring 83, and transmits the clamping force through the connecting block 82 to fix it to the outside of the cylinder 74, thereby completing the fixation of the new second annular cylinder 79. The equipment is started, and the linear module 5 is driven by the control board 3 to move the drilling mechanism 7 as a whole, so that the drill bit 76 is aligned with the position to be drilled on the workpiece; the servo motor 73 is started, driving the rotating shaft 75 and the drill bit 76 to rotate at high speed, while the linear module 5 drives the drilling mechanism 7 to move downward; as the drilling mechanism moves downward, the second annular cylinder 79 first contacts and is pressed against the base 1 or the surface of the workpiece, causing the circular plate 77 to slide upward relative to the cylinder 74; the limiting ring 710 moves upward along the limiting groove 711, compressing the telescopic spring 714 to deform it, and the deformation force is transmitted to the pressure sensor 713; the pressure sensor 713 detects a pressure signal and transmits it to the control board 3. The control board 3 immediately starts the vacuum cleaner 6. The vacuum cleaner vacuums the drilling area through the input end, collecting metal debris and dust generated during drilling. The drill bit 76 continues to descend to complete the drilling process. During this period, the vacuum cleaner 6 continues to work until the drilling mechanism 7 moves upward and resets after drilling is completed: the second annular cylinder 79 disengages, the telescopic spring 714 releases its elastic force, and drives the limit ring 710 back to the bottom of the limit groove 711. The pressure sensor 713 loses pressure. After receiving the signal, the control board 3 shuts off the vacuum cleaner 6, completing a single drilling operation.
