Description

Technical Field

[0001] This invention relates to a dental floss machine, and more particularly to a dental floss machine ... Prior Technology

[0002] An existing thread rolling machine is suitable for performing a thread rolling process on a semi-finished screw. The existing thread rolling machine includes a fixed base and a movable base spaced apart, two thread plate seats respectively disposed on the fixed base and the movable base, and two thread plates respectively disposed on opposite sides of the thread plate seats. In use, the semi-finished screw is guided between the thread plates, and then the movable base is driven to move relative to the fixed base. The thread plates then form threads on the outer peripheral surface of the semi-finished screw, thereby producing the finished screw.

[0003] However, existing thread rolling machines suffer from increased defect rates due to inaccurate assembly or loosening of components caused by vibration and wear. To address this, some manufacturers have developed an adjustment unit comprising two locking screws that pass laterally through the fixed base and are screwed into the thread plate holder, and four adjusting screws that are laterally screwed into the fixed base and abut against the thread plate holder. During adjustment, the operator needs to manually rotate the locking screws to adjust the lateral position of the thread plate holder relative to the fixed base. Alternatively, the operator can rotate the adjusting screws to adjust the yaw angle of the thread plate holder. However, manual adjustment is inconvenient and not only is it difficult to precisely control the angle, but it also cannot adjust the position and angle in other directions. Therefore, the design of the adjustment unit in existing thread rolling machines still needs improvement. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a tooth tread plate adjustment device for a tooth rolling machine that can overcome at least one disadvantage of the prior art.

[0005] Therefore, the tooth plate seat adjustment device of the tooth rolling machine of the present invention includes a fixed seat, a tooth plate seat, a first adjustment unit, a second adjustment unit, and a third adjustment unit.

[0006] The mounting base includes a base portion and a boss portion protruding upward from the top surface of the base portion.

[0007] The tooth plate is seated between the top surface of the base portion and one side of the boss portion.

[0008] The first adjustment unit includes an upper pad placed under the toothed plate seat, a lower pad placed under the upper pad, a first motor disposed on the fixed base, and a first adjustment member screwed onto the lower pad along a front-rear direction and driven by the first motor. The upper pad includes an upper inclined surface located on the bottom side and inclined along the front-rear direction, and the lower pad includes a lower inclined surface located on the top side and abutting against the upper inclined surface. The first motor drives the first adjustment member to rotate, causing the lower pad to move along the front-rear direction, while the upper pad abuts against the toothed plate seat and moves along a vertical direction.

[0009] The second adjustment unit can be used to adjust the vertical position or angle of the tooth plate seat relative to the fixed seat. The second adjustment unit includes at least one second locking member that passes through the base portion, the lower pad, the upper pad and the tooth plate seat along the vertical direction.

[0010] The third adjustment unit can be used to adjust the left and right position or angle of the tooth plate seat relative to the fixed seat. The third adjustment unit includes a third locking member that passes through the boss portion along a left and right direction and is screwed into the tooth plate seat, and several third adjustment members that are screwed onto the boss portion along the left and right direction and abut against the tooth plate seat.

[0011] The advantage of this invention is that, by setting the first adjustment unit, the second adjustment unit and the third adjustment unit, the three-dimensional position and angle of the tooth plate seat can be adjusted, which has the effect of good adjustability.

[0014] The mounting base 1 includes a base portion 11 and a boss portion 12 protruding upward from the top surface of the base portion 11.

[0015] The tooth plate seat 2 is located between the top surface of the base portion 11 and one side of the boss portion 12. The tooth plate seat 2 includes a plate side surface 21 adjacent to the boss portion 12, a bottom rotating surface 22 disposed on the bottom side, and a parallel pin 23 protruding downward from the bottom rotating surface 22. The bottom rotating surface 22 is generally in the shape of an inverted U-shape with a central concave shape and symmetrical downward sloping sides.

[0016] Referring to Figures 2, 3, and 4, the first adjustment unit 3 includes an upper pad 31 placed below the toothed plate seat 2, a lower pad 32 placed below the upper pad 31 and on the top surface of the base portion 11, a first motor 33 disposed on the front side of the fixed base 1, and a first adjustment member 34 screwed onto the lower pad 32 along a front-rear direction 6 and driven by the first motor 33. The upper pad 31 includes a top rotating surface 311 disposed on the top side and supporting the bottom rotating surface 22 of the toothed plate seat 2, an upper inclined surface 312 located on the bottom side and inclined along the front-rear direction 6, and a limiting groove 313 for the parallel pin 23 to be inserted and limited to vertical translation. The top rotating surface 311 is an upwardly convex arc shape, contacting the left and right sides of the bottom rotating surface 22, allowing the bottom rotating surface 22 to rotate left and right against it to change its angle. The lower pad 32 includes a lower inclined surface 321 located on the top side and abutting against the upper inclined surface 312. The first adjusting member 34 is a screw.

[0017] The second adjustment unit 4 can be used to adjust the vertical position or angle of the toothed plate seat 2 relative to the fixed seat 1. The second adjustment unit 4 includes two second supports 41 spaced apart along the front-rear direction 6 and disposed on the base portion 11, two second pads 42 rotatably disposed below the second supports 41, and two second locking members 43 disposed along a vertical direction 7 and directly connecting the fixed seat 1 and the toothed plate seat 2. Each second locking member 43 is a hydraulic cylinder, including a second cylinder body 431 mounted below the corresponding second pad 42, and a second shaft 432 movably extending from the second cylinder body 431. The second shaft 432 passes upward through the corresponding second pad 42, the second support 41, the lower pad 32, and the upper pad 31 and is screwed into the toothed plate seat 2. It should be noted that the number of second locking members 43 is not limited to two; depending on actual needs, it can be one, three, etc.

[0018] Referring to Figures 2, 3, and 5, the third adjustment unit 5 can be used to adjust the left-right position or angle of the toothed plate seat 2 relative to the fixed seat 1. The third adjustment unit 5 includes a third support 51 disposed along a left-right direction 8 on one side of the boss portion 12 opposite to the toothed plate seat 2, a third pad 52 disposed rotatably on one side of the third support 51 away from the boss portion 12, a third locking member 53 disposed along the left-right direction 8 and laterally connecting the fixed seat 1 and the toothed plate seat 2, four third adjustment members 54 disposed along the left-right direction 8 and located around the third locking member 53, and four third motors 55 respectively used to drive the third adjustment members 54. The third locking member 53 is a hydraulic cylinder, including a third cylinder body 531 mounted on one side of the third pad 52, and a third shaft 532 movably extending from the third cylinder body 531. The third shaft 532 passes through the third pad 52, the third support 51, the boss portion 12, and is screwed into the toothed plate seat 2. Each of the third adjusting members 54 is a screw, screwed onto the boss portion 12 and abutting against the side 21 of the toothed plate seat 2. Each of the third motors 55 is mounted on the boss portion 12 and connected to the corresponding third adjusting member 54, and can be controlled to rotate the third adjusting member 54. It should be noted that the number of the third motors 55 is the same as the number of the third adjusting members 54, and the number of the third adjusting members 54 is not limited to four, and can be varied according to actual needs.

[0019] Referring to Figures 2 to 5, when the tooth rolling machine has processing errors, the operator can adjust the first adjustment unit 3, the second adjustment unit 4 and the third adjustment unit 5 to change the position or angle of the tooth plate seat 2 relative to the fixed seat 1, so as to correct the aforementioned processing errors.

[0020] When adjusting the first adjustment unit 3, simply drive the first adjustment member 34 to rotate using the first motor 33. Since the lower pad 32 is located between the base 11 and the upper pad 31 and cannot rotate accordingly, the lower pad 32 will move relative to the front-back direction 6 when the first adjustment member 34 rotates. Through the wedge-shaped inclined surface design of the lower inclined surface 321 and the upper inclined surface 312, the upper pad 31 can move along the up-down direction 7 to push against and drive the toothed plate seat 2 to adjust its vertical position.

[0021] When the second adjustment unit 4 is to be adjusted, the second cylinder 431 of the second locking member 43 on the side to be adjusted is driven, so that the second shaft 432 moves relative to the second cylinder 431 along the vertical direction 7, thereby driving the tooth plate seat 2 to move closer to or further away from the base portion 11, thereby adjusting the vertical position or angle of the tooth plate seat 2 relative to the fixed seat 1.

[0022] To adjust the third adjustment unit 5, simply drive the third cylinder 531 of the third locking member 53, causing the third shaft 532 to move relative to the third cylinder 531 along the left-right direction 8. This will automatically move the toothed plate seat 2 closer to or further away from the boss portion 12. Furthermore, by driving the third motor 55 at the corner requiring adjustment and rotating the corresponding third adjustment member 54, the length of the third adjustment member 54 protruding from the boss portion 12 can be precisely adjusted. This pushes and changes the position of the corner of the toothed plate seat 2 at that location. The bottom rotating surface 22 of the toothed plate seat 2 will then rotate left-right against the top rotating surface 311 of the upper pad 31, thereby adjusting the left-right sway angle of the toothed plate seat 2 relative to the fixed seat 1.

[0023] In summary, the tooth plate seat adjustment device of the tooth rolling machine of the present invention, through the design of the first adjustment unit 3, the second adjustment unit 4 and the third adjustment unit 5, can accurately adjust the three-dimensional position and angle of the tooth plate seat 2, which has the effects of convenient use and good adjustability, and thus can indeed achieve the purpose of the present invention.

[0024] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification shall still fall within the scope of the patent of the present invention.
