Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] Please refer to 1-3, a metal fastener production punching device includes: a first conveying mechanism 1, a second conveying mechanism 2 and a tilting cabinet 3 are sequentially arranged on one side of the first conveying mechanism 1, a drilling mechanism 4 is arranged in a direction perpendicular to the tilting surface of the tilting cabinet 3, a limiting groove 31 is provided on the tilting surface of the tilting cabinet 3, a slide plate 8 is slidably arranged in the tilting cabinet 3, four limiting rods 81 are fixedly connected to the slide plate 8, a clamping mechanism 9 slides in the limiting groove 31, and the limiting rod 81 can prevent the clamping mechanism 9 from sliding down along the limiting groove 31.

[0025] Specifically, the utility model clamps and fixes the fastener 99 through the clamping mechanism 9, realizes automatic displacement of the clamping mechanism 9 through the inclined surface of the tilting cabinet 3, and limits the fastener 99 in cooperation with the limit rod 81, and then uses the drilling mechanism 4 to drill and chamfer the fastener 99 clamped on the clamping mechanism 9, that is, through the extension and retraction of the limit rod 81, the clamping mechanism 9 in the limit groove 31 is phased down by a distance, thereby ensuring that the position of the fastener 99 is not changed, and drilling and chamfering are realized in turn, thereby improving the precise correspondence between the chamfer position and the drilling position, improving the aesthetics of the fastener 99, and at the same time improving the efficiency of fastener 99 processing.

[0026] Furthermore, a first rotating shaft 10 is rotatably arranged in the tilting cabinet 3 , a sector gear 6 is fixedly sleeved on the first rotating shaft 10 , a rack 7 is fixedly connected to one side of the slide plate 8 , the rack 7 is connected to the tilting cabinet 3 through a spring 71 , and the sector gear 6 is meshed with the rack 7 .

[0027] Specifically, refer to Figure 1 The tilting cabinet 3 is rotatably arranged in the tilting cabinet 3, and the spring 71 is a compression spring. One end of the spring 71 is fixedly connected to the rack 7, and the other end of the spring 71 is fixedly connected to the inner wall of the tilting cabinet 3. The first rotating shaft 10 rotates, and then the coaxial fan gear 6 drives the rack 7 to slide in the tilting cabinet 3. After the fan gear 6 rotates past the rack 7, the fan gear 6 loses engagement with the rack 7, and the rack 7 returns to its initial position under the elastic force of the spring 71; a motor and a harmonic reducer are arranged on the outside of the tilting cabinet 3, which are used to drive and adjust the speed of the first rotating shaft 10.

[0028] Furthermore, the first rotating shaft 10 is connected to the transmission shaft of the first conveying mechanism 1 through a chain 5 .

[0029] Specifically, refer to Figure 1 The first rotating shaft 10 and the transmission shaft of the first conveying mechanism 1 are linked by the chain 5. The transmission shaft of the first conveying mechanism 1 is the second rotating shaft 11 in the figure, so that the conveying speed of the first conveying mechanism 1 is coordinated with the extension and retraction rate of the rack 7.

[0030] Furthermore, the clamping mechanism 9 includes a base 91, a placement groove 911 is provided on the base 91, the base 91 is connected to a movable plate 93 through a tension spring 92, a plug-in column 931 is fixedly connected to the movable plate 93, the plug-in column 931 is inserted into the base 91, a fastener 99 is mounted in the placement groove 911, a hexagonal groove 932 is provided on the movable plate 93, and a part of the fastener 99 extends into the hexagonal groove 932.

[0031] Specifically, refer to Figure 3 The tension spring 92 is sleeved on the outside of the plug-in column 931, and the two ends are fixedly connected to the base 91 and the movable plate 93 respectively. When the fastener 99 is clamped in the clamping mechanism 9, the movable plate 93 is first pulled away from the base 91 for a distance. At this time, the tension spring 92 is in a force storage state, and then the fastener 99 is placed in the placement groove 911, and the hexagonal end of the fastener 99 is clamped into the hexagonal groove 932. Finally, the fastener 99 is clamped in the clamping mechanism 9 under the elastic force of the tension spring 92.

[0032] Furthermore, two baffles 12 are arranged side by side directly above the first conveying mechanism 1 .

[0033] Specifically, refer to Figure 1A straight groove is formed between the two baffles 12 , and the clamping mechanism 9 is placed between the two baffles 12 to ensure that the clamping mechanism 9 can accurately enter the limiting groove 31 . The baffles 12 are installed on a support frame on which the first conveying mechanism 1 is installed.

[0034] Furthermore, four slide grooves 32 are provided in the tilting cabinet 3 , the four limiting grooves 31 are connected to the slide grooves 32 , and the four limiting rods 81 correspond to the four slide grooves 32 one by one.

[0035] Specifically, refer to Figure 2 The movement of the slide plate 8 drives the four limit rods 81 to slide in the slide groove 32 , so that the limit rods 81 regularly extend into the limit groove 31 to intercept the clamping mechanism 9 in the limit groove 31 .

[0036] Furthermore, two drilling bits 41 and two chamfering bits 42 are sequentially arranged on the drilling mechanism 4 .

[0037] Specifically, refer to Figure 2 By sequentially setting two drilling bits 41 and chamfering bits 42, the purpose is that the first drilling bit 41 drills the fastener 99, and the second drilling bit 41 performs secondary drilling on the already drilled hole to remove the burrs in the hole, and then the chamfering bit 42 is used to chamfer the hole, and the second chamfering bit 42 performs deburring work, so that the fastener 99 is more beautiful.

[0038] In this utility model, reference is made to Figures 1 to 3 First, the fastener 99 is installed in the clamping mechanism 9, and then the multiple clamping mechanisms 9 are placed between the two baffles 12 in sequence. The first rotating shaft 10 drives the first conveying mechanism 1 to work after being driven by the chain 5, and the clamping mechanism 9 moves to the limit groove 31. After the clamping mechanism 9 enters the limit groove 31, the fastener 99 is drilled and chamfered in sequence. As the first rotating shaft 10 rotates, when the sector gear 6 is not engaged with the rack 7, the limit rod 81 extends into the limit groove 31 under the elastic force of the spring 71, and the clamping mechanism 9 is intercepted in the limit groove 31. At this time, the drilling mechanism 4 moves downward, so that the drilling drill bit 41 or the chamfering drill bit 42 The fastener 99 is processed, and after the sector gear 6 and the rack 7 are engaged, the first rotating shaft 10 continues to rotate, and the limit rod 81 gradually retracts into the slide groove 32, that is, the limit rod 81 no longer blocks the clamping mechanism 9, and the clamping mechanism 9 slides down in the limit groove 31. Then, after the sector gear 6 and the rack 7 lose engagement, under the action of the elastic force of the spring 71, the limit rod 81 immediately extends into the limit groove 31, stops the clamping mechanism 9, and performs the next step of punching and chamfering operations. Subsequently, the fastener 99 in the clamping mechanism 9 is subjected to the drilling, grinding, chamfering, and grinding processes in sequence, and is finally transported to the next process by the second conveying mechanism 2.

[0039] In the utility model, the drilling process of the fastener 99 is carried out on the inclined surface of the inclined cabinet 3, and the coolant used in the drilling process flows down along the limit groove 31, which is convenient for the discharge and collection of the coolant. At the same time, the coolant washes away the debris accumulated in the limit groove 31, making it convenient for the clamping mechanism 9 to slide down in the limit groove 31.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
