Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and more specifically, to an energy-saving CNC machine tool with power failure protection. Background Technology

[0002] Energy-saving CNC machine tools are machine tools specifically designed to reduce energy consumption and improve energy efficiency. With increasing global attention to environmental protection and sustainable development, energy-saving technologies are becoming increasingly important in the industrial manufacturing sector. Energy-saving CNC machine tools with power-off protection are designed to improve production efficiency and energy utilization while ensuring that ongoing work is not lost in the event of a sudden power outage and that work can be quickly resumed.

[0003] However, energy-saving CNC machine tools lack effective protection measures in actual use, which makes it easy for the workpiece to be damaged or even the key components of the machine tool to be damaged once the power is cut off, increasing maintenance costs and equipment downtime.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an energy-saving CNC machine tool with power failure protection to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An energy-saving CNC machine tool with power failure protection includes a machine tool and a protective component 1. The protective component 1 includes a motor mounted on the adjustment structure of the machine tool, a cutter mounting seat at one end of the motor, a protective frame on one side of the adjustment structure of the machine tool, and multiple electric telescopic rods on one side of the protective frame. A limiting plate is provided at one end of each electric telescopic rod.

[0008] Furthermore, in order to better protect the energy-saving CNC machine tool from power failure, a second protective component is provided on one side of the machine tool. The second protective component includes an auxiliary box located on one side of the machine tool. The inner wall of the auxiliary box is equipped with a transformer, a control main board, and a storage battery. The inner wall of the auxiliary box is equipped with a wire fixing seat. The wire fixing seat has wire fixing grooves that are evenly distributed. The inner walls of the wire fixing grooves have auxiliary holes on both sides. The inner walls of the auxiliary holes are fixed with spring-loaded telescopic rods. One end of the spring-loaded telescopic rods is fixed with a wire fixing plate.

[0009] Furthermore, in order to better assist in the maintenance of electrical components or wiring inside the auxiliary box, maintenance openings and wiring holes are respectively provided on the top and one side of the auxiliary box. A maintenance cover is hinged to the inner wall of the maintenance opening, and multiple latches are provided on one side of the maintenance cover and one side of the auxiliary box.

[0010] Furthermore, in order to better facilitate heat dissipation for the electrical components inside the auxiliary box, heat dissipation vents are provided on both sides of the auxiliary box. Filter covers are snapped onto the inner walls of the heat dissipation vents, and filter screens and molecular sieves are installed on the inner walls of the filter covers.

[0011] Furthermore, in order to better reduce the damage caused by the limiting plate to the adjustment structure, an anti-slip pad is provided on one side of the limiting plate, and one side of the anti-slip pad is adapted to the limiting plate.

[0012] Furthermore, in order to better improve the stability of the machine tool, equal-distance adjustment holes are provided at the bottom of the machine tool, and adjustment seats are threaded to the inner wall of the adjustment holes.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) The protective component one installed on the machine tool can not only respond quickly at the moment of power failure, but also restrict and fix the adjustment structure of the machine tool to prevent the machine tool parts from moving out of control due to sudden power failure. It can also assist the rotation of the cutting tool mounting seat and the cutting tool, effectively avoiding damage to the workpiece and the key components of the machine tool. At the same time, the protective component two installed on the machine tool can not only maintain stable operation for a short time after power failure, maintain the current processing state or take emergency measures to reduce maintenance costs and equipment downtime, but also automatically clamp wires of different sizes to prevent the wires from loosening or falling off due to vibration during the operation of the machine tool, thereby avoiding electrical faults such as short circuits and open circuits caused by poor wire connection, and improving the safety and reliability of the entire equipment.

[0015] (2) By setting the maintenance cover and latch in the auxiliary box, the maintenance and repair of electrical components in the auxiliary box can be made very convenient, which improves production efficiency. At the same time, the filter cover, filter screen and molecular sieve plate set in the auxiliary box can not only effectively prevent external dust and debris from entering and damage to electrical components caused by accidental collisions, but also ensure the heat dissipation requirements of electrical components during operation, reducing safety hazards and maintenance costs caused by electrical faults.

Adjustment seats 10 are threaded to the inner wall of the adjustment holes to assist in the adjustment when the energy-saving CNC machine tool is placed on an uneven surface, so that the energy-saving CNC machine tool is in the same horizontal position.

[0028] Example 2:

[0029] like Figures 1-5 As shown, according to an embodiment of the present invention, an energy-saving CNC machine tool with power failure protection is provided on one side of the machine tool 1. The protective component 3 includes an auxiliary box 301 provided on one side of the machine tool 1, which is used to house a transformer 302, a control motherboard 303, a reserve battery 304, or other control components. The inner wall of the auxiliary box 301 is provided with the transformer 302, the control motherboard 303, and the reserve battery 304. The transformer 302 is used for voltage conversion to ensure uniform input voltage. The control motherboard 303 is used to control the operation of the energy-saving CNC machine tool and power switching (power management) to ensure that the energy-saving CNC machine tool can operate stably when the power is off. The reserve battery 304 is used as a backup power source to reduce damage to the energy-saving CNC machine tool when the power is off.

[0030] The inner wall of the auxiliary box 301 is provided with a wire fixing seat 305, which is used to restrict and fix the wires connected to the transformer 302, control board 303, storage battery 304 or other control components. The wire fixing seat 305 is provided with wire fixing grooves distributed at equal intervals for placing wires. The inner walls of the wire fixing grooves are provided with auxiliary holes on both sides. The inner walls of the auxiliary holes are fixed with spring-loaded telescopic rods 306. The spring-loaded telescopic rods 306 are composed of telescopic rod one (small diameter), telescopic rod two (large diameter) and their springs. One end of telescopic rod one is nested with the inner wall of telescopic rod two through a sealing block or sealing gasket. The spring is fitted outside telescopic rod one and telescopic rod two for adaptive adjustment according to the wire size. One end of the spring-loaded telescopic rods 306 is fixed with a wire fixing plate 307 for fixing and clamping the placed wires to prevent the placed wires from loosening.

[0031] In actual use, the transformer 302 and the control board 303 are electrically connected by a power input line (not shown in the figure). One end of the power input line is electrically connected to a power plug (not shown in the figure) in actual use. The transformer 302, the control board 303 and the storage battery 304 are electrically connected.

[0032] A maintenance port and a wiring hole are respectively opened on the top and one side of the auxiliary box 301. A sealing sleeve (not shown in the figure) is provided at the junction of the power input line and the wiring hole. It is used to maintain the electrical components and wires inside the auxiliary box 301 and the installation of the power input line. A maintenance cover 4 is hinged to the inner wall of the maintenance port to shield and protect the electrical components of the auxiliary box 301. Two latches 5 are provided on one side of the maintenance cover 4 and one side of the auxiliary box 301 to improve the tightness between the maintenance cover 4 and the auxiliary box 301. Heat dissipation vents are opened on both sides of the auxiliary box 301 to help dissipate the heat generated by the electrical components inside the auxiliary box 301 during use. A filter cover 6 is snapped onto the inner wall of the heat dissipation vent to install the filter screen plate 7 and the molecular sieve plate 8. The filter screen plate 7 and the molecular sieve plate 8 are installed on the inner wall of the filter cover 6 to help filter impurities or moisture in the outside air.

[0033] Machine tool 1, its adjustment structure, electric telescopic rod 204, transformer 302, control main board 303, storage battery 304, or other control components are all existing technologies and will not be described in detail. Furthermore, the specific model and specifications (circuit connection method) need to be set or adjusted according to the actual situation of the device.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In summary, with the help of the above-mentioned technical solution of this utility model, when the external power supply of the energy-saving CNC machine tool is suddenly interrupted, the control motherboard 303 immediately detects the power failure signal by real-time monitoring of the circuit status and triggers the protection mechanism. The reserve battery 304 starts synchronously to provide temporary power to the key components and maintain the system's short-term operation.

[0036] At the same time, the electric telescopic rod 204 extends rapidly after receiving the power failure signal, pushing the limiting plate 205 into contact with the adjustment structure of the machine tool 1. The anti-slip pad 9 on the surface of the limiting plate 205 increases the frictional resistance and locks the adjustment structure of the machine tool 1, such as the tool moving axis, to prevent the components from losing control due to inertia or gravity. Meanwhile, the motor 201 is powered by the reserve battery 304 at the moment of power failure. The motor 201 drives the cutter mounting base 202 to complete the last auxiliary rotation, so that the tool is removed from the surface of the workpiece and avoids damage caused by the collision between the tool and the workpiece.

[0037] The transformer 302 converts the output voltage of the storage battery 304 into the voltage required by the machine tool 1, ensuring continuous power supply to the control system and key components, maintaining operation or safe shutdown procedures in emergency situations. The spring-loaded telescopic rod 306 inside the wire holder 305 adapts to the extension and retraction of the wire size. The spring-loaded telescopic rod 306 drives the wire holder 307 to clamp the wire, preventing the wire from loosening or falling off due to vibration during machine tool 1 operation, and avoiding short circuit or open circuit faults.

[0038] During power outages, the heat dissipation vents on both sides of the auxiliary box 301 filter dust and moisture in the air through the filter screen plate 7 and molecular sieve plate 8 inside the filter cover 6, ensuring stable heat dissipation of internal electrical components and preventing overheating damage. When maintenance is required, the maintenance cover 4 can be quickly opened through the latch 5, facilitating the inspection and maintenance of electrical components inside the auxiliary box 301 or the replacement of the reserve battery 304, reducing downtime. The adjustment seat 10 is connected to the adjustment hole at the bottom of the machine tool 1 through a thread, allowing the height of the machine tool 1 to be adjusted according to the flatness of the ground, ensuring the overall stability of the machine tool 1 during power outages and preventing the protective components from failing due to tilting.

[0039] When the external power is restored, the control board 303 automatically switches back to the main power supply, the electric telescopic rod 204 retracts, the limiting plate 205 releases the lock on the adjustment structure, the motor 201 drives the cutter mounting base 202 to return to the previous rotation position, the cutter continues to process the surface of the workpiece, and the machine tool 1 returns to normal operation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
