[0002] Thread rolling machines are professional equipment used in the production of screws. They come in various specifications, such as automatic thread rolling machines, flatbed thread rolling machines, semi-automatic thread rolling machines, fully automatic thread rolling machines, and high-speed thread rolling machines. Thread rolling machines are lightweight, flexible, efficient, and possess advantages that other similar equipment cannot replace. They avoid the limitations of lathes, drilling machines, or manual tapping, saving time and labor, reducing the risk of thread damage, and preventing tap breakage.

[0003] Existing thread rolling machines generally use a combination of moving and stationary rolling plates to process the surface of parts. However, the machining chips generated during thread rolling can stick together, especially on aluminum parts. Therefore, it is necessary to clean the moving and stationary rolling plates in a timely manner to reduce the impact of machining chips on subsequent thread rolling processes. Utility Model Content

[0011] As an optional solution for the high-precision fine-pitch thread rolling machine of this utility model, an airbag ring is installed inside the spray hole;

[0012] Inflating the airbag ring is used to reduce or increase the diameter of the nozzle.

[0013] As an optional solution for the high-precision fine-pitch thread rolling machine of this utility model, wherein: a first tube is installed inside the insert, one end of the first tube is connected to the inside of the air bag ring, and liquid is transmitted to the inside of the air bag ring through the first tube.

[0014] As an optional solution for the high-precision fine-pitch thread rolling machine of this utility model, the thickness of the moving rolling plate gradually increases;

[0015] The movable washboard is used to squeeze the insert pin to slide to one end;

[0016] The static rubbing plate has an adjustment cavity inside, and a transmission pipe is installed at one end of the static rubbing plate. The transmission pipe is used to transmit liquid into the adjustment cavity.

[0017] A second pipe is also installed at one end of the static rubbing plate, which is used to transfer liquid into the interior of the insertion column;

[0018] A partition plate is also installed at one end of the square plate. The partition plate passes through the stationary rubbing plate and the adjustment cavity.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1-4 One type of high-precision fine-pitch thread rolling machine includes:

[0034] Base 1;

[0035] The movable rubbing plate 2 and the stationary rubbing plate 3 are used to clamp the workpieces being processed.

[0036] Square plate 5 is slidably connected to one end of stationary rubbing plate 3. One end of square plate 5 is connected to a post 6, which is used to slidably connect to the inclined groove on moving rubbing plate 2.

[0037] The nozzle 7 is located on one side of the insert post 6. Lubricating fluid is sprayed through the nozzle 7 to flush away the machining chips at the moving rubbing plate 2 and the inclined groove.

[0038] according to Figure 1 As shown, when the part is located between the moving rubbing plate 2 and the stationary rubbing plate 3, the driving component 4 installed on the upper end of the base 1 drives the moving rubbing plate 2 to slide back and forth. In this way, the moving rubbing plate 2 drives the part to be rubbed on the stationary rubbing plate 3, thereby realizing the thread rolling of the part. The driving component 4 is a rotating wheel and an eccentric plate. The eccentric plate is installed at a position away from the axis of the rotating wheel, so that when the rotating wheel rotates, it will pull the eccentric plate to slide back and forth.

[0039] Furthermore, according to Figure 2 As shown, when machining chips remain on the moving rubbing plate 2, the pin 6 at one end of the stationary rubbing plate 3 is inserted into the groove at one end of the moving rubbing plate 2. Thus, when the moving rubbing plate 2 slides, the pin 6 remains stationary, allowing the pin 6 to slide in the groove at one end of the moving rubbing plate 2, thereby cleaning the machining chips remaining on the moving rubbing plate 2.

[0040] Furthermore, in order to better clean up machining chips, a spray hole 7 is provided at one end of the insert 6. Coolant is sprayed through the spray hole 7 to cool the parts and the moving rubbing plate 2, thereby reducing the residual machining chips. Secondly, the high pressure of the spray hole 7 is used to flush the moving rubbing plate 2, thereby further reducing the residual machining chips at the moving rubbing plate 2, thus improving the thread rolling effect of subsequent parts.

[0041] Example 2

[0042] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-2 One end of the square plate 5 is rotatably connected to a ball 8, and one end of the insert 6 is connected to one end of the ball 8;

[0043] A spring 9 is also installed at one end of the square plate 5. One end of the spring 9 is connected to the upper end of the plug 6, and the plug 6 is reset by the spring 9.

[0044] Since the groove on the processing surface of one end of the moving scoop plate 2 is a slanted groove, its insert 6 needs to be adjustable to fit the slanted groove. Therefore, a ball 8 is installed at one end of the insert 6. The ball 8 is rotatably connected to one end of the square plate 5, so that the insert 6 can be adjusted at any angle through the ball 8, so that the insert 6 can slide better in the groove, thereby improving the removal effect.

[0045] Example 3

[0046] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 1-4 An airbag ring 12 is installed inside the nozzle 7;

[0047] The inflatable airbag ring 12 is used to reduce or increase the diameter of the nozzle 7.

[0048] according to Figure 4As shown, when the moving washboard 2 slides away from the nozzle 7, the hydraulic pressure sprayed from the nozzle 7 will be reduced when it contacts the moving washboard 2 and the parts, thus reducing the scouring effect. Therefore, an airbag ring 12 is installed inside the nozzle 7. When the moving washboard 2 moves the parts away from the nozzle 7, liquid is filled into the airbag ring 12 to expand it. The expanded airbag ring 12 reduces the inner diameter of the nozzle 7, thereby increasing the hydraulic pressure sprayed from the nozzle 7. This ensures that the coolant hydraulic pressure sprayed from the nozzle 7 can always scouring the moving washboard 2 and the parts, thus improving the removal effect.

[0049] Example 4

[0050] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figures 1-4 The insert 6 has a first tube 13 installed inside it. One end of the first tube 13 is connected to the inside of the airbag ring 12, and liquid is transferred to the inside of the airbag ring 12 through the first tube 13.

[0051] The thickness of the moving washboard 2 gradually increases;

[0052] The movable washboard 2 is used to squeeze the insert 6 to slide to one end;

[0053] The static rubbing plate 3 has an adjustment chamber 16 inside, and a transmission pipe 14 is installed at one end of the static rubbing plate 3. The transmission pipe 14 is used to transmit liquid into the adjustment chamber 16.

[0054] A second tube 15 is also installed at one end of the static rubbing plate 3. The second tube 15 is used to transfer liquid into the interior of the insertion column 6.

[0055] A partition plate 17 is also installed at one end of the square plate 5. The partition plate 17 passes through the stationary rubbing plate 3 and the adjustment cavity 16. A through hole 18 is provided at one end of the partition plate 17. The through hole 18, the transmission pipe 14 and the adjustment cavity 16 are connected.

[0056] A slide bar 10 is installed at the other end of the square plate 5, and the slide bar 10 passes through one end of the static washboard 3;

[0057] A spring 11 is fitted at one end of the slide rod 10, and the slide rod 10 is connected to the square plate 5 by the spring 11.

[0058] Liquid is transmitted through the transmission pipe 14 into the adjustment chamber 16, then through the adjustment chamber 16 to the second pipe 15, and finally through the second pipe 15 to the insertion post 6, so that the nozzle 7 can be ejected.

[0059] according to Figure 4As shown, since the thickness of the movable washboard 2 gradually increases from one side to the other, when the movable washboard 2 slides, the gradually thickening movable washboard 2 will squeeze the insert 6 and the square plate 5 to slide to one end. The square plate 5 drives the partition plate 17 to slide, thereby connecting the through hole 18 with the adjustment cavity 16. Liquid is transmitted into the adjustment cavity 16 through the transmission pipe 14, so that the liquid enters the first pipe 13 from the through hole 18. The first pipe 13 is used to transmit the liquid to the airbag ring 12, thereby expanding the airbag ring 12 and reducing the size of the nozzle 7.
