Technical Field

[0001] The present invention relates to the technical field of electrical cabinets, and in particular to a vibration-proof device for a machine tool electrical cabinet and a use method thereof. Background Art

[0002] The machine tool electrical cabinet is a key device in machine tool equipment used to install and protect electrical components and control machine tool operation. It integrates various electrical control and protection components such as circuit breakers, contactors, relays, inverters, PLCs, etc. Through scientific wiring and reasonable layout, it realizes power distribution and signal transmission for machine tool motor drive, spindle control, feed motion, cooling and lubrication systems.

[0003] In order to facilitate transportation together with the machine tools, the existing small and medium-sized CNC machine tool electrical cabinets are generally installed on the machine tool housing. However, for machine tools with strong vibration, a series of problems such as loosening and damage of electrical components are prone to occur when the electrical cabinet is installed on the machine tool housing, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a machine tool electrical cabinet vibration prevention device and use method. Summary of the Invention

[0004] The main purpose of the present invention is to provide a machine tool electrical cabinet anti-vibration device and a method of use, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A vibration-proof device for a machine tool electrical cabinet and a method of use thereof include an electrical cabinet body, wherein the rear wall and one side wall of the electrical cabinet body are each provided with a group of slide rail mechanisms, the lower end of the electrical cabinet body is provided with a shock-absorbing mechanism, the lower end of the electrical cabinet body is provided with four groups of protruding cylinders, the rear wall and one side wall of the electrical cabinet body are each provided with a group of concave grooves, the slide rail mechanism is installed in the middle of the concave groove, the interior of the concave groove is provided with a positioning screw hole, and the rear end of the slide rail mechanism is provided with a sliding female head, and the sliding female head and the positioning screw hole are detachably connected by bolts.

[0006] Preferably, a sliding female head is provided at the other end of the slide rail mechanism, the sliding male head and the sliding female head are installed with a gap, and the sliding male head and the sliding female head are slidably connected.

[0007] Preferably, a disc base is provided at the lower end of the shock absorbing mechanism, a spring is nested in the middle of the upper end of the disc base, and a nut is connected to the upper end of the disc base above the spring.

[0008] Preferably, a sliding groove is provided in the middle of the interior of the sliding female head, a guide chamfer is provided at the upper end of the sliding groove, and two groups of mounting screw holes are symmetrically provided on both sides of the sliding female head.

[0009] Preferably, a convex cylinder is provided on the side wall of the sliding male head, and the convex cylinder is engaged and slidably connected with the sliding groove, and two groups of countersunk holes are symmetrically provided on both sides of the sliding male head.

[0010] Preferably, a sliding shaft is provided in the middle of the disc base, the sliding shaft is installed with clearance fit with the protruding cylinder, the outer wall of the upper end of the disc base is provided with a thread, and the nut is threadedly connected to the thread.

[0011] Preferably, S1: Slide rail mechanism installation: fix the sliding female head to the corresponding installation position of the machine tool through the four mounting screw holes, use the guide chamfer at the end of the sliding groove to insert the convex cylinder on the side wall of the sliding male head into the middle of the sliding groove, so that the sliding male head can slide freely in the middle of the sliding female head, then align the four countersunk holes on the mounting surface of the sliding male head with the positioning screw holes inside the concave groove, and use bolts to fix the sliding male head to the inside of the concave groove on the side of the electrical cabinet body; S2: Install the shock absorber mechanism: Nest the spring outside the sliding shaft of the disc base, then install the sliding shaft of the disc base and the protruding cylinder at the bottom of the electrical cabinet body with clearance fit, and then screw the nut onto the thread at the end of the disc base to constrain the maximum position of the spring to prevent it from loosening; S3: Shock absorption working process: The electrical cabinet body slides within a certain range through the slide rail mechanism. When the electrical cabinet body is vibrated by the machine tool, the spring in the shock absorption mechanism absorbs and buffers the energy generated by the vibration through compression and rebound, thereby reducing the impact of the vibration on the electrical components inside the electrical cabinet body.

[0012] Preferably, in said S2, the clearance between the sliding shaft of the disc base and the protruding cylinder at the bottom of the electrical cabinet body is 0.05-0.10 mm.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, while ensuring that the CNC machine tool can be transported together with the machine tool, the electrical cabinet and the CNC machine tool shell can be effectively physically isolated when the machine tool is in use, and an elastic shock-absorbing device is installed at the bottom of the electrical cabinet to prevent the vibration of the CNC machine tool from being transmitted to the electrical cabinet, greatly reducing the impact of vibration on the precision electrical components inside the electrical cabinet, reducing the probability of faults such as loose components and poor contact caused by vibration, and extending the service life of the electrical components.

[0014] In the present invention, the guide chamfer at the end of the sliding groove inside the sliding female head provides precise guidance for the installation of the sliding male head, and cooperates with the positioning screw holes in the concave groove on the side of the electric cabinet to ensure that the installation position of the slide rail device is accurate. The sliding shaft of the disc base cooperates with the micro-gap of the protruding tube at the bottom of the electric cabinet, and the nut constrains and fixes the spring to ensure that the shock absorber is installed firmly. The precise installation design makes the structure of the entire shockproof device stable. Even under the long-term vibration conditions of the machine tool, it can still maintain good shock absorption performance without problems such as loosening or falling off of components, providing continuous and reliable shock protection for the electrical cabinet.

[0015] In the present invention, the slide rail device and the shock-absorbing device adopt a modular design and are fixed to the electrical cabinet and the installation base respectively by bolt connection. This installation method is convenient for flexible adaptation and adjustment according to machine tool electrical cabinets of different models and sizes. When the device fails or the performance deteriorates, it is only necessary to remove the bolts of the corresponding parts to quickly replace and repair individual components such as the sliding female head, sliding male head, and spring. There is no need to disassemble the entire device on a large scale, which reduces the maintenance difficulty and maintenance cost and improves the ease of use and maintenance efficiency of the shock-absorbing device of the machine tool electrical cabinet.
