Technical Field

[0001] The utility model belongs to the technical field of hole-opening equipment, and particularly relates to a hole-opening device for nut processing. Background Technique

[0002] During the processing of nuts, it is necessary to drill holes in them, and hole-opening equipment is required during the drilling process.

[0003] The existing hole-opening equipment consists of an operating table, a clamping mechanism, and a liftable drilling machine. The nut is longitudinally clamped on the axis line below the drilling machine through the clamping mechanism, and the descending drilling machine performs axial drilling operations on the nut. The existing clamping mechanism consists of two mutually movable clamping blocks. The nut is located between the two clamping blocks. However, the existing clamping blocks do not have a device for positioning the nut, resulting in poor hole position accuracy in nut processing. At the same time, the clamping and fixing of the clamping blocks are poor. When the nut loosens during the hole-opening processing of the nut thread, it is very easy to cause damage to the hole-opening device and the nut itself, resulting in unnecessary losses. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hole-opening device for nut processing to solve the problems raised in the above background technique.

[0006] Preferably, a clamping plate for restricting the processing nut in the positioning groove is provided above the operating table. A clamping groove for accommodating the rod part of the processing nut is opened on the side wall of the clamping plate. A fixing member for fixing is provided between the clamping plate and the operating table.

[0007] Preferably, the fixing member includes two metal blocks and two electromagnets. Two mounting holes are symmetrically opened on the operating table. The two electromagnets are respectively installed at the bottoms of the two mounting holes. The two metal blocks are respectively arranged at both ends of the bottom of the clamping plate, and the two metal blocks can be respectively adsorbed on the corresponding electromagnets.

[0008] Preferably, a lifting rod for lifting is further provided between the clamping plate and the metal block. One end of the lifting rod extends in a lifting manner into the mounting hole.

[0009] Preferably, a spring for moving the metal block closer to the electromagnet is further provided in the mounting hole. The spring is sleeved on the lifting rod, and one end of the spring abuts against the metal block.

[0010] Preferably, a mounting bin for accommodating the clamping mold is further opened at the top of the operating table. Two positioning holes are symmetrically opened in the mounting bin, and two positioning columns inserted into the corresponding positioning holes are symmetrically provided at the bottom of the clamping mold.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) By adding the clamping mold and the positioning groove, the utility model can position the processing nut on the processing axis below the drilling machine body, realizing the function that the device can position the processing nut. At the same time, by replacing different clamping molds, different sizes of processing nuts can be clamped and processed.

[0013] (2) By adding the clamping plate and the fixing member, the fixing member can limit the end of the processing nut in the positioning groove through the clamping plate, thereby preventing the processing nut from loosening and falling off.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figure 1 As shown, an opening device for nut processing provided by the present invention includes: an operating table 1 and a drill press body 4 that can be lifted above the operating table 1. A detachable clamping mold 6 is provided on the top of the operating table 1. Different-sized positioning grooves 15 are respectively opened at the top of each clamping mold 6. A processing nut 5 is inserted into the positioning groove 15, and the processing nut 5 is arranged on the processing axis below the drill press body 4.

[0023] In the above, when using the operating table 1, the drill press body 4, the clamping mold 6 and the processing nut 5 provided by the present invention, select the corresponding clamping mold 6 according to the size of the processing nut 5 to be processed, install the selected clamping mold 6 on the operating table 1, and insert the processing nut 5 into the clamping mold 6 through the positioning groove 15. At this time, the processing nut 5 is positioned through the positioning groove 15, and at this time, the processing nut 5 can be positioned and drilled through the drill press body 4.

[0024] Further, in order to facilitate the positioning and installation of the clamping mold 6 in the installation bin 7, referring to Figures 2 - 4 As shown, an installation bin 7 for accommodating the clamping mold 6 is further opened at the top of the operating table 1. Two positioning holes 9 are symmetrically opened in the installation bin 7. Two positioning columns 8 inserted into the corresponding positioning holes 9 are symmetrically provided at the bottom of the clamping mold 6. The clamping mold 6 is positioned and inserted into the corresponding positioning hole 9 through the positioning column 8, thereby preventing the clamping mold 6 from rotating in the installation bin 7 during the drilling of the drill press body 4 and improving the installation stability of the clamping mold 6.

[0025] In the present invention, in combination with Figure 2 and Figure 5 As shown, a clamping plate 3 for restricting the processing nut 5 in the positioning groove 15 is provided above the operating table 1 of this embodiment. A clamping groove 2 for accommodating the rod portion of the processing nut 5 is opened on the side wall of the clamping plate 3. A fixing member for fixing is provided between the clamping plate 3 and the operating table 1.

[0026] In the above, when using the clamping plate 3 provided by the present invention, after the processing nut 5 is inserted into the positioning groove 15, the clamping plate 3 is clamped on the rod portion of the processing nut 5 through the clamping groove 2. At this time, the clamping plate 3 is fixed on the operating table 1 through the fixing member, thereby fixing and clamping the processing nut 5 in the positioning groove 15.

[0027] Further, to facilitate the quick fixation of the clamping plate 3 on the operating table 1, refer to Figure 2 As shown, the fixing member includes two metal blocks 11 and two electromagnets 10. Two mounting holes 12 are symmetrically formed on the operating table 1. The two electromagnets 10 are respectively mounted at the bottoms of the two mounting holes 12. The two metal blocks 11 are respectively arranged at both ends of the bottom of the clamping plate 3, and the two metal blocks 11 can be respectively adsorbed on the corresponding electromagnets 10. After the processing nut 5 is positioned and inserted into the positioning groove 15, the clamping plate 3 is clamped on the processing nut 5 through the clamping groove 2. At this time, the two metal blocks 11 are respectively placed on the corresponding magnets. When the magnets are energized, the clamping plate 3 is fixed on the operating table 1, so as to clamp the processing nut 5 in the positioning groove 15 and prevent the processing nut 5 from loosening and detaching during processing.

[0028] Further, to prevent the clamping plate 3 from detaching from the operating table 1, refer to Figure 2 As shown, a lifting rod 14 for lifting is further provided between the clamping plate 3 and the metal block 11. One end of the lifting rod 14 extends in a lifting manner into the mounting hole 12. The clamping plate 3 can be adjusted in height above the operating table 1 through the lifting rod 14, which not only prevents the clamping plate 3 from detaching from the operating table 1 but also facilitates the processing nut 5 to detach from the positioning groove 15.

[0029] Further, to facilitate the close fit between the metal block 11 and the electromagnet 10, refer to Figure 2 As shown, a spring 13 for approaching the metal block 11 to the electromagnet 10 is further provided in the mounting hole 12. The spring 13 is sleeved on the lifting rod 14, and one end of the spring 13 abuts against the metal block 11. When the clamping plate 3 is not stressed, the elastic force of the spring 13 automatically expands, so that the metal block 11 fits on the electromagnet 10, which is convenient for the metal block 11 to be adsorbed on the electromagnet after the electromagnet 10 is energized.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
