DETAILED DESCRIPTION

[0020] 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.

[0021] Embodiment 1:

[0022] Please refer to Figure 1-4 A combined bolt thread rolling device for avoiding invalid threads comprises a workbench 1, a servo motor 2 is fixedly installed on the right surface of the workbench 1, a driving gear 3 is movably installed on the right inner wall of the workbench 1, and a driven gear 4 is meshedly connected to the outer surface of the driving gear 3, a first screw rod 5 is fixedly installed on the left surface of the driving gear 3, a second screw rod 6 is fixedly installed on the left surface of the driven gear 4, a first thread rolling plate 7 is threadedly connected to the outer surface of the first screw rod 5, and a second thread rolling plate 8 is threadedly connected to the outer surface of the second screw rod 6, a telescopic rod 9 is fixedly installed on the upper surface of the workbench 1, a fixed plate 10 is fixedly installed on the upper end of the telescopic rod 9, a circular plate 11 is movably installed in the middle of the fixed plate 10, a storage groove 12 is opened on the upper surface of the circular plate 11, a bolt workpiece 13 is arranged inside the storage groove 12, and threaded mounting plates 22 are fixedly installed on both sides of the first thread rolling plate 7 and the second thread rolling plate 8.

[0023] Specifically: During the use of the utility model, when it is necessary to roll the bolt workpiece 13, firstly, according to the length of the bolt workpiece 13, a first rolling plate 7 and a second rolling plate 8 whose height is greater than the length of the bolt workpiece 13 are installed, and the rolling plates are installed by the cooperation of the threaded mounting plate 22 and the bolts. After the installation is completed, the bolt workpiece 13 is placed inside the storage groove 12. At this time, the rotating plate 18 is manually turned clockwise, and the rotating plate 18 drives the third screw rod 15 to rotate clockwise, thereby driving the pressing plate 16 to move downward. In the process of moving downward, the pressing plate 16 gradually enters the interior of the storage groove 12, thereby pressing the storage groove 1 2 generates a downward pressure on the bolt workpiece 13 inside, and the supporting force of the storage groove 12 is used to limit and fix the bolt workpiece 13. After the limit and fixation is completed, the servo motor 2 is started, thereby driving the driving gear 3 to rotate clockwise, and the driving gear 3 rotates clockwise, thereby driving the driven gear 4 to rotate counterclockwise, so that the first screw rod 5 rotates clockwise, and the second screw rod 6 rotates counterclockwise, thereby driving the first thread rolling plate 7 and the second thread rolling plate 8 to move in a direction close to each other, until the first thread rolling plate 7 and the second thread rolling plate 8 contact the surface of the bolt workpiece 13, and then the surface of the bolt workpiece 13 is threaded.

[0024] In this embodiment: a mounting frame 14 is fixedly installed on the upper surface of the fixed plate 10, a third screw rod 15 is threadedly connected to the middle of the mounting frame 14, a pressing plate 16 is fixedly installed on the lower end of the third screw rod 15, a silicone pad 17 is fixedly installed on the lower surface of the pressing plate 16, and a rotating plate 18 is fixedly installed on the upper surface of the third screw rod 15.

[0025] Specifically: manually turn the rotating plate 18 clockwise, the rotating plate 18 drives the third screw rod 15 to rotate clockwise, thereby driving the pressure plate 16 to move downward. During the downward movement, the pressure plate 16 gradually enters the interior of the storage groove 12, thereby generating a downward pressure on the bolt workpiece 13 inside the storage groove 12, and the bolt workpiece 13 is limited and fixed by the supporting force of the storage groove 12. This design can clamp the bolt workpiece 13 being processed, and avoid the situation where the bolt workpiece 13 is easily moved during the thread rolling process, thereby affecting the thread rolling quality.

[0026] In this embodiment: the output end of the servo motor 2 is fixedly connected to the right surface of the driving gear 3, the right surface of the driven gear 4 is movably connected to the left inner wall of the workbench 1, a slide groove is provided on the upper surface of the workbench 1, and the inner wall of the slide groove is movably connected to the lower surfaces of the first thread rolling plate 7 and the second thread rolling plate 8.

[0027] Specifically, the function of the slide groove is to provide a supporting force for the movement of the first thread rolling plate 7 and the second thread rolling plate 8.

[0028] In this embodiment, the size of the pressing plate 16 matches the size of the storage slot 12 .

[0029] Specifically, after the pressing plate 16 enters the storage groove 12 , the outer surface of the pressing plate 16 fits with the inner wall of the storage groove 12 , so that it is not easy to shake, thereby ensuring the limiting effect.

[0030] Working principle: The utility model installs a new thread rolling plate to adjust the height of the thread rolling plate, so that bolt workpieces 13 of different lengths can be threaded. At the same time, the height of the thread rolling plate will be higher than the length of the bolt workpiece 13, thereby ensuring that the entire workpiece 13 can be threaded to avoid invalid threads. Compared with related technologies, the utility model provides a combined bolt thread rolling device to avoid invalid threads, which has the following beneficial effects: the design can achieve the effect of processing bolt workpieces 13 of different lengths, and always ensure that the height of the thread rolling plate is greater than the length of the bolt workpiece 13, thereby avoiding invalid threads. At the same time, the bolt workpiece 13 being processed can be clamped to avoid the bolt workpiece 13 from moving during the thread rolling process, thereby affecting the thread rolling quality.

[0031] Embodiment 2:

[0032] Please refer to Figure 1-4 A through hole 19 is provided on the upper surface of the workbench 1 , a collecting frame 20 is fixedly mounted on the lower surface of the workbench 1 , and a collecting box 21 is movably mounted on the inner wall of the collecting frame 20 .

[0033] Specifically: when the bolt workpiece 13 is threaded, debris will be generated. After processing, the debris falls downward due to its own gravity. The debris falling downward passes through the through hole 19 and falls into the collection box 21. The collection box 21 collects the debris. When the debris is collected to a certain extent, the collection box 21 is manually pulled out, so that the debris inside the collection box 21 is uniformly processed manually.

[0034] In this embodiment: the collection box 21 and the collection frame 20 are designed as drawers.

[0035] Specifically: the drawer design facilitates the subsequent extraction and cleaning of the collection box 21.
