Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 As shown:

[0028] A numerical control machine tool with a rapid positioning device comprises a processing table 1 and a numerical control machine tool body 2 mounted on the surface of the processing table 1.

[0029] In this implementation scheme: the existing public (announcement) number: CN215394043U discloses an automatic loading and unloading device for CNC machine tools; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when installing the railing, multiple people are required to hold the cross pipe and insert the cross pipe into the sleeve for installation, which is a waste of manpower, and during the installation, it is easy to cause shaking through human support, which is inconvenient for personnel to align the installation, thereby affecting the installation speed of the guardrail and affecting the progress of the project". In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a fixing mechanism 3 and a cleaning mechanism 4 are added to the application document.

[0030] like Figure 1-Figure 4 As shown:

[0031] More specifically:

[0032] In combination with the above content, the fixing mechanism 3 includes an electric telescopic rod 31 fixedly connected to the four corners of the upper surface of the processing table 1, a fixed rod 32 rotatably connected to the output end of the electric telescopic rod 31 through a bearing A, and a screw 36 arranged inside the fixed rod 32, and the bottom end of the screw 36 is rotatably connected to a pressure plate 37 through a bearing B.

[0033] In this embodiment: when the workpiece needs to be fixed, first place the workpiece to be processed at the center of the upper surface of the processing table 1, then rotate the fixing rod 32 to adjust the position of the pressing plate 37, move the pressing plate 37 to the workpiece, and then start the electric telescopic rod 31 to retract, and drive the pressing plate 37 to press and fix the workpiece through the fixing rod 32, so as to achieve rapid fixation of the workpiece, which is simple and convenient to operate and highly practical.

[0034] It should be noted that the fixed rod 32 is connected to the output end of the electric telescopic rod 31 through a damping bearing, so that the fixed rod 32 is not easily moved by accidental contact with the outside.

[0035] Going further:

[0036] In combination with the above content, a slider 35 is provided inside the fixed rod 32, and a slide groove 34 is opened on the side of the fixed rod 32 close to the slider 35, and the slider 35 and the fixed rod 32 are slidably connected through the slide groove 34, and the screw 36 is rotatably connected to the inside of the slider 35 through the bearing C, and a limit block 310 with a U-shaped structure is provided on the upper surface of the fixed rod 32, and the screw 36 is screwed inside the limit block 310, and a plurality of groups of first blocks 33 arranged at equal intervals are fixedly connected to the upper surface of the fixed rod 32, and a second block 39 is fixedly connected to the side of the surface of the limit block 310 close to the first block 33, and an anti-slip pad 38 is fixedly connected to the bottom surface of the pressure plate 37.

[0037] In this embodiment: when the workpiece needs to be fixed, first place the workpiece to be processed at the center position of the upper surface of the processing table 1, then rotate the fixing rod 32 to adjust the position of the pressure plate 37, move the pressure plate 37 to the workpiece, and then start the electric telescopic rod 31 to retract, and drive the pressure plate 37 to press and fix the workpiece through the fixing rod 32. During this period, the second clamping block 39 on the surface of the limit block 310 is driven to separate from the first clamping block 33 by rotating the screw rod 36, and the screw rod 36 is pushed to make the slider 35 slide inside the slide groove 34, so that the position of the pressure plate 37 on the surface of the fixing rod 32 can be adjusted, and then the second clamping block 39 is driven to engage with the first clamping block 33 by reversing the screw 36, and the position of the pressure plate 37 is locked, so that workpieces of different sizes can be fixed by the pressure plate 37. After the workpiece is fixed, the workpiece can be processed by the CNC machine tool body 2.

[0038] It should be noted that the anti-slip pad 38 can increase the friction between the pressing plate 37 and the workpiece, and increase the stability of the pressing plate 37 in fixing the workpiece.

[0039] It should be noted that the cross-sectional shape of the slide groove 34 is a cross structure, so that the screw rod 36 can slide inside the fixing rod 32 through the slide groove 34 .

[0040] Going further:

[0041] In combination with the above content, a cleaning mechanism 4 is provided on the surface of the processing table 1, and the cleaning mechanism 4 includes fixed blocks 41 symmetrically fixedly connected to both sides of the upper surface of the processing table 1, and electromagnets 42 fixedly connected to opposite sides of the two groups of fixed blocks 41, and an insertion groove 44 opened inside the processing table 1 near the side of the electromagnet 42, and a collection box 43 is placed inside the insertion groove 44.

[0042] In this implementation scheme: after the processing is completed, by energizing the electromagnet 42, the electromagnet 42 will attract the metal debris on the surface of the processing table 1, which is convenient for the staff to clean up the debris generated by the processing and improve the processing environment of the CNC machine tool. After the debris adsorption is completed, the electromagnet 42 is powered off, and the metal debris on the surface of the electromagnet 42 will fall into the collection box 43, which is convenient for taking out the collection box 43 and uniformly processing the debris inside the collection box 43.

[0043] It should be noted that the electric telescopic rod 31 and the electromagnet 42 are both electrically connected to an external power source via wires.

[0044] Working principle: After the processing is completed, the electromagnet 42 is energized, and the electromagnet 42 will attract the metal debris on the surface of the processing table 1, which is convenient for the staff to clean up the debris generated by the processing and improve the processing environment of the CNC machine tool. After the debris adsorption is completed, the electromagnet 42 is powered off, and the metal debris on the surface of the electromagnet 42 will fall into the collection box 43, which is convenient for taking out the collection box 43 and uniformly processing the debris inside the collection box 43.

[0045] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention to solve the problems raised in the above background technology.
