Description

Technical Field

[0001] The invention mainly relates to the technical field of hexagonal nut production, and in particular to a punching device for hexagonal nut production. Background Art

[0002] The main uses and functions of nuts include fixing, preventing loosening, balancing stress, etc. There are many types of nuts in general. According to the shape, they include hexagonal nuts, round nuts, square nuts, etc. The inside of the hexagonal nut is six equilateral hexagonal depressions, which are used in conjunction with threaded rods, bolts and washers to fix and tighten. In engineering, hexagonal nuts are widely used in various machinery, equipment, vehicles, aircraft and other fields to fix connecting rods, shafts, gears, wheels and other components. They are the most widely used and most versatile nuts; Before the hexagonal nut is tapped, the center of the blank needs to be punched. When punching, the blank needs to be positioned. In the prior art, the positioning is usually completed by a cylinder pushing a clamping plate to clamp the two sides of the blank. However, due to the limited area on both sides of the blank of the hexagonal nut, the clamping area is small and the positioning effect is not good. Summary of the invention

There are six connecting sleeves, which are arranged along the circumference of the puncher and fixedly installed on the top of the punching table. A driven sliding connecting rod is matched and installed in the connecting sleeve, and a positioning block is provided at one end of the connecting rod close to the puncher.

[0005] Furthermore, the lifting mechanism includes a mounting plate, the puncher is mounted at the bottom of the mounting plate, a telescopic cylinder that is telescopic in the vertical direction is connected to the center of the top of the mounting plate, and sliding rods extending in the vertical direction are arranged on both sides, the sliding rods are slidably connected to the first bracket, and the telescopic cylinder is fixedly connected to the first bracket.

[0006] Furthermore, a baffle is fixedly mounted on the other end of the connecting rod, and the baffle is pushed by a first spring arranged on the connecting rod to abut against the side wall of the linkage wheel, and the linkage wheel is eccentrically fixed to the first rotating rod rotatably mounted on the punching table.

[0007] Furthermore, a first gear is fixedly mounted on the first rotating rod, six of the first gears are meshedly connected with second gears, and the second gears are fixedly connected to a second rotating rod rotatably mounted on the punching table.

[0008] Furthermore, a second bracket is fixedly installed on the top of the punching table, and a transmission rod and a worm gear are rotatably installed on the second bracket. The transmission rod and the worm gear are connected by a pulley belt assembly. A third gear is fixedly installed on the transmission rod, and the third gear matches the rack arranged in the vertical direction on the mounting plate.

When the connecting rods arranged in the six connecting sleeves are driven to approach the hexagonal nut blank placed close to the punching table, the six positioning blocks keep moving synchronously until they are tightly abutted against the six side surfaces of the hexagonal nut blank respectively, so that the positioning of the hexagonal nut blank can be achieved, which is better than the traditional positioning effect achieved by clamping two side walls. The waste chips generated when the punching machine punches holes will be blocked by the first sleeve and the second sleeve to avoid splashing and pollution. When the punching head rotates to punch holes, the fan blades will also rotate, which can blow the waste chips into the discharge trough and fall into the collection box through the second rotating rod for collection.

[0019] See attached Figure 1-6 A punching device for hexagonal nut production includes a punching table 1, a first bracket 2 is fixedly mounted on the punching table 1, a lifting mechanism 3 is arranged on the first bracket 2, and the lifting mechanism 3 is connected to a puncher 4 driven to lift and lower; The punching table 1 is also provided with a hexagonal positioning mechanism 5, which includes a connecting sleeve 501. There are six connecting sleeves 501, which are arranged along the circumference of the puncher 4 and fixedly installed on the top of the punching table 1. A driven sliding connecting rod 502 is matched and installed in the connecting sleeve 501, and a positioning block 503 is provided at one end of the connecting rod 502 close to the puncher 4.

[0020] In this embodiment, there are six connecting sleeves 501 and they are arranged along the circumference of the punching machine 4. When the connecting rods 502 arranged in the six connecting sleeves 501 are driven to approach the hexagonal nut blank placed close to the surface of the punching table 1, the six positioning blocks 503 maintain synchronous movement until they are tightly abutted against the six side surfaces of the hexagonal nut blank respectively, thereby realizing the positioning of the hexagonal nut blank. Compared with the traditional positioning effect achieved by clamping two side walls, the punching machine 4 is finally driven down by the lifting mechanism 3 to perform punching processing on the hexagonal nut blank.

[0021] The lifting mechanism 3 includes a mounting plate 301, the punch 4 is mounted at the bottom of the mounting plate 301, a telescopic cylinder 303 that is telescopic in the vertical direction is connected to the top center of the mounting plate 301, and sliding rods 302 that extend in the vertical direction are arranged on both sides, the sliding rods 302 are slidably connected to the first bracket 2, and the telescopic cylinder 303 is fixedly connected to the first bracket 2.

[0022] In this embodiment, after the telescopic cylinder 303 is started, the mounting plate 301 can be driven to move up and down, and during this process, the sliding rod 302 will slide with the first bracket 2 to make the lifting process more stable.

[0023] A baffle 505 is fixedly mounted on the other end of the connecting rod 502 . The baffle 505 is pushed by a first spring 504 provided on the connecting rod 502 to abut against the side wall of the linkage wheel 506 . The linkage wheel 506 is eccentrically fixed to a first rotating rod 507 rotatably mounted on the punching table 1 .

[0024] In this embodiment, when the first rotating rod 507 rotates, the interlocking wheel 506 eccentrically connected thereto rotates eccentrically, and the first spring 504 can push the baffle plate 505 to always abut against the side wall of the interlocking wheel 506, so that the connecting rod 502 can be driven to slide back and forth in the connecting sleeve 501, so that the positioning block 503 is close to or away from the hexagonal nut blank.

[0025] A first gear 508 is fixedly mounted on the first rotating rod 507 , and six of the first gears 508 are meshedly connected with second gears 509 . The second gears 509 are fixedly connected to a second rotating rod 510 rotatably mounted on the punching table 1 .

[0026] In this embodiment, when the second rotating rod 510 is driven to rotate, the second gear 509 fixedly connected thereto rotates synchronously, which can cooperate with the meshing transmission to drive the six first gears 508 to rotate synchronously, that is, the six first rotating rods 507 rotate synchronously, which can drive the six positioning blocks 503 to move synchronously towards or away from the hexagonal nut blank.

[0027] A second bracket 7 is fixedly installed on the top of the punching table 1, and a transmission rod 8 and a worm 9 are rotatably installed on the second bracket 7. The transmission rod 8 and the worm 9 are connected by a pulley belt assembly 10. A third gear 11 is fixedly installed on the transmission rod 8, and the third gear 11 matches with a rack 12 arranged in the vertical direction on the mounting plate 301. The worm 9 is meshingly connected with a worm wheel 13 fixedly installed on one of the first rotating rods 507.

[0028] In this embodiment, when the telescopic cylinder 303 drives the mounting plate 301 to descend and the puncher 4 synchronously descends to punch holes in the hexagonal nut blank, the rack 12 synchronously descends, and the transmission rod 8 is driven to rotate through the meshing transmission with the third gear 11, and then the worm 9 is driven to rotate synchronously through the pulley belt assembly 10. The worm 9 then drives one of the first rotating rods 507 through the meshing transmission with the worm wheel 13, and the six first rotating rods 507 are driven to rotate synchronously through the meshing transmission of the six first gears 508 and the second gears 509, so that the six positioning blocks 503 can be driven to synchronously approach the hexagonal nut blank and clamp and position its six side walls. Similarly, after the punching of the hexagonal nut blank is completed, when the telescopic cylinder 303 drives the mounting plate 301 to rise and the puncher synchronously rises and moves away from the hexagonal nut blank, the six positioning blocks 503 will synchronously move away from the hexagonal nut blank and release the positioned hexagonal nut blank.

[0029] In the above embodiment, when the punching head of the punching machine 4 abuts against the hexagonal nut blank, the six positioning blocks 503 have abutted against the six side walls of the hexagonal nut blank, and the rack 12 will disengage from the third gear 11, so the positioning block 503 will not continue to approach the hexagonal nut blank, and the engagement between the worm wheel 13 and the worm 9 is self-locking, even if the rack 12 disengages from the third gear 11, it will not affect the positioning effect of the positioning block 503.

[0030] The second rotating rod 510 is hollow inside and is connected to the discharge trough 101 opened on the surface of the punching table 1, and a collection box 15 with an open top is placed below the discharge trough 101; the punching machine 4 is provided with a chip blocking mechanism 6, and the chip blocking mechanism 6 includes a first sleeve 601 and a second sleeve 602, and the punching head of the punching machine 4 is located on the inner side of the first sleeve 601 and the second sleeve 602, and a fan blade 14 is fixedly installed thereon, one end of the first sleeve 601 is fixedly installed on the punching machine 4, and the other end is provided with an annular groove 6011, the second sleeve 602 is slidably connected to the annular groove 6011, and the ends of the two are connected by a second spring 603.

[0031] In this embodiment, the punching machine 4 continues to descend to punch holes in the hexagonal nut blank, and the second sleeve 602 cooperates with the second spring 603 to slide in the annular groove 6011. The punching head of the punching machine 4 is always located in the first sleeve 601 and the second sleeve 602, so the generated waste chips will be blocked by the first sleeve 601 and the second sleeve 602 to avoid splashing and causing pollution. When the punching head rotates to punch holes, the fan blade 14 will also rotate, which can blow the generated waste chips into the discharge trough 101 and fall into the collection box 15 through the second rotating rod 510 for collection.

[0032] In the above embodiment, the second rotating rod 510 includes a multi-section rotating rod 5101, the head and tail ends of which are connected to each other through threads. When the inside of the multi-section rotating rod 5101 is blocked by waste chips, the waste chips can be removed by disassembling each other.

[0033] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
