Description

Technical Field

[0001] This utility model relates to a teeth-rubbing machine, specifically an adjustable teeth-rubbing machine. Background Technology

[0002] See Figure 1 The existing thread rolling machine 1 includes a machine base 11, a guide rail 12 disposed on the machine base 11, a feeding device 13, a drive device 14, a fixed thread rolling plate 15, a movable thread rolling plate 16 driven by the drive device 14 and corresponding to the fixed thread rolling plate 15, and a sliding plate 17 disposed below the movable thread rolling plate 16 and sliding on the guide rail 12. The feeding device 13 can hold multiple blanks B and feeds the blanks B one by one between the fixed thread rolling plate 15 and the movable thread rolling plate 16. The guide rail 12 has a body 121. And an inclined surface 122 protruding from the body 121, and the bottom of the aforementioned sliding plate 17 slides against the inclined surface 122; when the thread rolling is to be performed, the blanks B are sequentially fed into the space between the movable thread plate 16 and the fixed thread plate 15 by the feeding device 13, and at the same time the driving device 14 drives the movable thread plate 16 and drives the sliding plate 17 to slide back and forth on the inclined surface 122. The blanks B are squeezed from both sides between the movable thread plate 16 and the fixed thread plate 15, so that the blanks B gradually form a complete screw product.

[0003] In actual use, it was found that during the thread rolling process, the sliding plate 17 slides back and forth and rubs against the inclined surface 122 at high speed. Over time, this can easily cause wear on the inclined surface 122, creating a gap between the bottom of the sliding plate 17 and the inclined surface 122. Since the guide rail 12 is fixedly mounted on the machine base 11 and cannot move, in other words, when the sliding plate 17 continuously rubs against the same surface of the inclined surface 122, the guide rail 12 will be damaged. Therefore, if the guide rail 12 cannot be replaced, the machine base 11 must be replaced. Otherwise, the stability of the sliding plate 17 will be reduced, which will affect the operation performance and accuracy of the thread rolling machine 1, and needs to be improved. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an adjustable thread rolling machine, which can maintain the stable use of the thread rolling machine's performance and accuracy through the adjustable guide rail design, thereby extending the service life of the thread rolling machine.

[0005] Therefore, the adjustable tooth rolling machine of this utility model includes a machine base, a guide rail, a feeding device, a driving device, a fixed tooth plate, a movable tooth plate driven by the driving device and corresponding to the fixed tooth plate, and a sliding plate disposed under the movable tooth plate and sliding on the guide rail. The feeding device can hold multiple blanks and feed the multiple blanks one by one between the fixed tooth plate and the movable tooth plate. The guide rail has a body and an inclined surface protruding from the body. The bottom of the aforementioned sliding plate slides against the inclined surface. The guide rail is movably disposed on the machine base. Long slots are opened on both sides of the body, and a locking fastener is locked on the long slot. The locking fastener positions the body on the machine base. Therefore, when the guide rail wears out due to the reciprocating sliding of the sliding plate, by loosening or releasing multiple locking fasteners and displacing the guide rail, the inclined surface can be made to fit against the bottom of the sliding plate, thereby maintaining the stability of the sliding plate and thus maintaining the performance, accuracy and extending the service life of the tooth rolling machine.

[0037] The foregoing and other technical contents, features and effects of this utility model will become clear in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0038] See Figure 2 , Figure 3 In a preferred embodiment of the present invention, the tooth rolling machine package 3 includes a machine base 31, a guide rail 32 disposed on the machine base 31, a feeding device 33, a driving device 34, a fixed tooth plate 35, a movable tooth plate 36 driven by the driving device 34 and correspondingly disposed to the fixed tooth plate 35, and a sliding plate 37 disposed below the movable tooth plate 36 and sliding on the guide rail 32; wherein, the guide rail 32 is movably disposed, having a body 321 and an inclined surface 322 protruding from the body 321, and the aforementioned body Long slots 323 are provided on both sides of 321. In this embodiment, four long slots 323 are arranged in pairs opposite each other. Each long slot 323 is correspondingly locked with a locking fastener A. The main body 321 is positioned on the machine base 31 by multiple locking fasteners A. At the same time, the bottom of the sliding plate 37 slides against the inclined surface 322. In addition, the feeding device 33 can hold multiple blanks B and feed multiple blanks B one by one between the fixed tooth plate 35 and the movable tooth plate 36 so that the movable tooth plate 36 can perform tooth rolling.

[0039] See Figure 2 , Figure 4 When thread rolling is to be performed, multiple blanks B are first sequentially fed into the space between the movable thread plate 36 and the fixed thread plate 35 by the feeding device 33. Then, the driving device 34 drives the movable thread plate 36, which in turn drives the sliding plate 37 to slide back and forth on the inclined surface 322. At the same time, the multiple blanks B placed between the movable thread plate 36 and the fixed thread plate 35 are continuously squeezed from both sides, gradually forming a complete screw product. During the thread rolling process, the sliding plate 37 slides back and forth and rubs against the inclined surface 322 at high speed. Over time, mutual wear will inevitably occur between the guide rail 32 and the sliding plate 37. After long-term use, a gap may easily form between the bottom of the sliding plate 37 and the inclined surface 322. If the sliding plate 37 is not dealt with in time, it will cause... When the sliding plate 37 slides, instability occurs, affecting the displacement accuracy of the sliding plate 37. In this embodiment, by loosening the multiple locking fasteners A that are locked in the long slot 323, and displacing the guide rail 32 within the range of the long slot 323 until the guide rail 32 abuts against the bottom of the sliding plate 37, so that the inclined surface 322 fits against the bottom of the sliding plate 37, the multiple locking fasteners A can be locked in place. At this time, the gap problem between the sliding plate 37 and the guide rail 32 is improved, greatly reducing the instability caused by the gap when the sliding plate 37 slides, effectively maintaining the stability of the sliding plate 37, thereby maintaining the performance and accuracy of the thread rolling machine 3, and effectively extending the service life of the thread rolling machine 3.

[0040] In summary, the adjustable tooth-rolling machine of this invention maintains the stability of the sliding plate as it slides on the guide rail through the adjustable design of the movable guide rail, thereby maintaining the performance, accuracy and extending the service life of the tooth-rolling machine.

[0041] The above description is only for illustrating preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the contents of the utility model specification should still fall within the scope of the present utility model patent.
