[0002] Tapping machines, as important equipment for processing internal threads, are widely used in industries such as automobile manufacturing and hardware processing. Before tapping a workpiece, the workpiece needs to be clamped and fixed. However, when fixing the workpiece, some irregular workpieces are often encountered. In order to fix workpieces with different shapes, different types of fixing fixtures need to be changed. This not only increases the workload of the workers, but also affects the efficiency of processing and makes it inconvenient to use the tapping machine. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-6 As shown, a tapping machine that is easy to fix includes a support platform 1. A guide plate 19 is fixedly connected to the inner cavity of the support platform 1. The tapping machine body 3 is fixedly connected to the top of the support platform 1. Several chip removal holes 4 are opened through the top of the support platform 1. A second clamping plate 6 is fixedly connected to the left side of the top of the support platform 1. A first clamping plate 8 is slidably connected to the right side of the top of the support platform 1. Guide posts 15 are fixedly connected inside both the first clamping plate 8 and the second clamping plate 6. A spring 18 is sleeved on the surface of the guide post 15. The other ends of the two guide posts 15 are slidably connected to the inside of two limiting blocks 9, respectively. Through the guiding action of the guide posts 15, the spring 18 can be assisted in guiding, making the spring 18 more stable when stretched or compressed, and preventing it from shifting randomly. A plug 10 is opened through the top of both the first clamping plate 8 and the second clamping plate 6. Several insertion holes for cooperating with the plug 10 are opened on the top of the limiting block 9. The plug 10 limits the movement of the limiting block 9. The positioning mechanism allows the limiting block 9 to be quickly and accurately fixed in a set position, thereby restricting the limiting block 9 from sliding freely inside the first clamping plate 8 and the second clamping plate 6, thus improving the stability of the limiting block 9 when clamping the workpiece. A motor 7 is provided on the right side of the support platform 1. The output shaft of the motor 7 is bolted with a threaded rod 16, and the other end of the threaded rod 16 is rotatably connected to the inner wall of the support platform 1. A connecting block 12 is threadedly connected to the surface of the threaded rod 16. Connecting columns 11 are fixedly connected to both the front and rear sides of the connecting block 12. A slider 17 is fixedly connected to the other end of the connecting column 11, and the other end of the slider 17 is fixed to the bottom of the first clamping plate 8. A circular slot 5 is provided on the side of the second clamping plate 6 facing the first clamping plate 8. The limiting blocks 9 are slidably connected inside the first clamping plate 8 and the second clamping plate 6. A spring 18 is fixedly connected to the other end of the limiting block 9, and the other ends of the springs 18 on both sides are fixed to the inside of the first clamping plate 8 and the second clamping plate 6, respectively.

[0024] A baffle 13 is fixedly connected inside the support platform 1, and the baffle 13 is located above the threaded rod 16. By blocking the threaded rod 16 above the baffle 13, the falling iron filings and oil stains can be guided, preventing the iron filings and oil stains from falling into the surface of the threaded rod 16, thereby causing the connecting block 12 to be obstructed when moving on the surface of the threaded rod 16.

[0025] The support platform 1 is internally fixedly connected to a limiting post 14, and the surface of the limiting post 14 is slidably connected to the inner protrusion of the bottom of the connecting block 12. Through the sliding cooperation between the limiting post 14 and the connecting block 12, the movement trajectory of the connecting block 12 can be precisely limited, preventing it from deviating during operation.

[0026] A collection box 2 is provided at the bottom of the inner cavity of the support platform 1, and the collection box 2 is located in front of the guide plate 19. Through the collection box 2 provided in front of the guide plate 19, the iron filings and oil stains falling on the guide plate 19 can automatically slide into the collection box 2 under the action of gravity and the tilt angle of the plate surface, thereby facilitating the collection of oil stains and iron filings.

[0027] It is worth noting that the technical features of the tapping machine body 3 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of the above technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0028] Working principle: When clamping and processing a relatively irregular workpiece, the bolt 10 inserted into the top of the first clamping plate 8 and the second clamping plate 6 is removed. Without the limiting effect of the bolt 10, the limiting block 9 will automatically move backward under the influence of spring force. The workpiece is then placed in the circular slot 5 opened in the second clamping plate 6. The motor 7 is then started. The output shaft of the motor 7 will drive the threaded rod 16 to rotate. Due to the rotation of the threaded rod 16, the connecting block 12, which is threaded to the threaded rod 16, will be forced to move to the left. Simultaneously, the connecting post 11 and the slider 17 connected to the connecting block 12 will cause the first clamping plate 8 to move to the left as well. When the limiting block 9 inside the first clamping plate 8 contacts the workpiece, it is forced to move backward due to the force of the workpiece. When the workpiece is squeezed, the limiting blocks 9 inside the first clamping plate 8 and the second clamping plate 6 will be forced to contract inward. When the first clamping plate 8 and the second clamping plate 6 clamp the workpiece, the motor 7 can be turned off. At this time, the plug 10 is re-inserted into the calibrated limiting block 9 for limiting, thereby completing the fixation of the irregular workpiece. When processing the regular workpiece, there is no need to remove the plug 10. The motor 7 can be started directly to drive the first clamping plate 8 to clamp the workpiece. When the tapping machine body 3 is working, the chip discharge hole 4 opened on the top of the support table 1 will discharge the oil and debris accumulated on the support table 1 into the guide plate 19 set inside the support table 1. Then, it is introduced into the collection box 2 on the front side through the inclined surface of the guide plate 19, so as to facilitate the collection of oil and iron filings.
