[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0028] The utility model provides a technical solution:

[0029] See also Figures 1 to 3A precision CNC machine tool processing positioning device comprises a machine tool body 1, a processing arm 2 is arranged on one side of the outer wall of the machine tool body 1, a control end 3 is arranged above the processing arm 2, a sliding groove 4 is opened on one side of the inner part of the machine tool body 1, and a feeding mechanism 5 is arranged on the inner wall of the sliding groove 4; the feeding mechanism 5 comprises a limit frame 501, the limit frame 501 is fixed to the inner wall of the sliding groove 4, a conveying device 502 is installed at the lower part of the limit frame 501, a damping spring 503 is embedded on one side of the inner part of the limit frame 501, one end of the damping spring 503 is connected to a pressing plate 504, and the pressing plate 504 is rotated away from the outer wall of the damping spring 503 A roller 505 is rotatably connected to the machine tool body 1, and a fixed plate 506 is arranged on one side of the limit frame 501 inside the machine tool body 1. A clamping block 507 is rotatably connected to the top of the fixed plate 506. The rollers 505 are evenly distributed about the outer wall of the pressing plate 504. The pressing plate 504 forms an elastic structure with the limit frame 501 through the damping spring 503. The limit frame 501 is slidably connected to the outer wall of the fixed plate 506 with a telescopic block 6. An electromagnet 7 is fixed to one end of the telescopic block 6 that passes through the limit frame 501. A first telescopic spring 9 is installed on the outer wall of the fixed plate 506 that faces the electromagnet 7. A pressing head 8 passes through the inside of the first telescopic spring 9.

[0030] By adopting the above technical scheme, the sheet metal parts are loaded along the conveying equipment 502 through the limit of the limit frame 501, and enter the clamping block 507 of the fixed plate 506 to wait for positioning, thereby avoiding manual loading and taking to improve efficiency, and the damping spring 503 elastically pushes the pressing plate 504, which is suitable for sheet metal parts of different thicknesses. At the same time, the roller 505 slides against the sheet metal parts to improve the smoothness of loading. When in the loading process, the electromagnet 7 is turned on, adsorbed on the first group of sheet metal parts, and approaches the metal fixed plate 506 and is magnetically adsorbed, thereby compressing the pressing head 8 to penetrate the switch inside the fixed plate 506, so that the micro motor embedded in the fixed plate 506 drives the clamping block 507 to rotate, and four groups of sheet metal parts can be loaded at the same time. When the four groups are loaded, the electromagnet 7 is powered off through the program control of the control end 3, and the telescopic block 6 is pushed to shrink and reset by the first telescopic spring 9, and the conveying equipment 502 is disconnected to avoid re-loading and causing accumulation.

[0031] Specifically, Figure 1 , Figure 4 and Figure 5As shown, a clamping mechanism 10 is provided inside the clamping block 507, and the clamping mechanism 10 includes a clamping rod 1001, the clamping rod 1001 passes through one side of the outer wall of the clamping block 507, and one end of the clamping rod 1001 passing through the clamping block 507 is sleeved with a sleeve 1002, and an iron core 1003 passes through one side of the clamping rod 1001 inside the sleeve 1002, and a coil 1004 is provided outside the end of the iron core 1003 passing through the sleeve 1002. 0 also includes a collar 1005, two collars 1005 are respectively fixed on the outer walls of the clamping rod 1001 and the sleeve 1002, a second telescopic spring 1006 is connected between the two collars 1005, a sliding structure is formed between the sleeve 1002 and the clamping rod 1001, the clamping rod 1001 is tightly fitted with the iron core 1003, a driving motor 11 is embedded on the other side of the outer wall of the machine tool body 1, and a driving rod 12 is connected to the power output end of the driving motor 11.

[0032] By adopting the above technical solution, when the micro motor under the fixing plate 506 is started, the corresponding coil 1004 is triggered, and the four groups of clamping mechanisms 10 of the clamping block 507 rotate in sequence, thereby triggering the corresponding coil 1004 to be energized. The energization time has a certain pause, which can fully clamp and fix the sheet metal. The coil 1004 is energized to allow the iron core 1003 to generate magnetic force, thereby pushing the clamping rod 1001 to slide along the sleeve 1002, and after passing through the clamping block 507, the sheet metal is fixed. Multiple clamping mechanisms 10 of each group of the clamping block 507 are vertically arranged to improve The clamping surface maintains the stability of clamping. When the processing is completed, the corresponding clamping mechanism 10 is rotated to face the unclosed front end of the machine tool body 1. After the coil 1004 is powered off, the two rings 1005 are driven by the second telescopic spring 1006 to drive the corresponding clamping rod 1001 to slide toward the sleeve 1002, so that the clamping rod 1001 is reset to facilitate the removal of the processed sheet metal. When different surfaces need to be processed, the driving motor 11 drives the driving rod 12 to rotate, so that the fixed plate 506 drives the clamping block 507, thereby flipping the sheet metal to process the other side.

[0033] Working principle: The processing arm 2 of the machine tool body 1 processes the sheet metal part, and the sheet metal part is limited by the limit frame 501 in the sliding groove 4, and moves to the clamping block 507 on the fixed plate 506 on the conveying equipment 502. The damping spring 503 elastically pushes the pressing plate 504 for further limiting, and cooperates with the roller 505 to improve the smooth movement of the sheet metal part. The electromagnet 7 is in the starting state when conveying the sheet metal part, which can adsorb the sheet metal part and allow the telescopic block 6 to extend until it touches the pressing head 8. At the same time, the fixed plate 506 is made of metal, which is convenient for adsorbing the electromagnet 7 to allow the pressing head 8 to penetrate the fixed plate 506 and touch the switch button of the clamping mechanism 10. The micro motor at the bottom of the fixed plate 506 drives the clamping block 507 to rotate, so that the four groups of clamping mechanisms 10 on the clamping block 507 clamp and position the sheet metal parts in turn, and in turn After the processing is carried out by the processing arm 2, the electromagnet 7 and the conveying equipment 502 are disconnected after the four groups of sheet metal parts are clamped, and the telescopic block 6 is reset by the first telescopic spring 9. When the clamping mechanism 10 is started, the coil 1004 is energized and the iron core 1003 pushes the permanent magnet material clamping rod 1001 to slide along the sleeve 1002, thereby passing through the clamping block 507 to contact and press and fix the sheet metal part. When the processing is completed, the coil 1004 is disconnected and the second telescopic spring 1006 between the two groups of rings 1005 is telescoped and reset, so that the clamping rod 1001 is reset to facilitate the removal of the sheet metal part. The driving motor 11 drives the driving rod 12 to facilitate the rotation of the fixed plate 506, and the clamping block 507 drives the four groups of sheet metal parts to rotate, which is convenient for processing different surfaces. The process program is written in advance through the control end 3 to achieve automation.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
