[0026] The adjusting tapping mechanism 4 comprises two sets of mounting frames 41 symmetrically arranged at the top of the supporting seat 2, wherein a movable plate 42 is movably arranged in the mounting frame 41, and a position adjusting component 4a for adjusting the position of the movable plate 42 is arranged outside the movable plate 42, and a driving motor 43 is arranged at the top of the movable plate 42, and a tap head 44 for processing the workpiece is connected to the output shaft of the driving motor 43. By accurately adjusting the position of the movable plate 42, it is ensured that the tap head 44 is always in the best position during the processing, thereby improving the processing accuracy and efficiency.

[0027] Furthermore, the position adjustment assembly 4a includes a mounting rod 4a1 disposed in one of the mounting frames 41, and a through slot for the mounting rod 4a1 to pass through is provided in the movable plate 42. The movable plate 42 is provided with stable support and movement direction restriction, ensuring the accuracy and stability of the adjustment.

[0028] Further, the position adjustment assembly 4a also includes a connecting column 4a4 rotatably arranged in the support seat 2 and a threaded rod 4a2 rotatably arranged in another set of mounting frames 41 and threadedly connected to the movable plate 42, a first bevel gear 4a3 is arranged outside the threaded rod 4a2, a second bevel gear 4a5 meshing with the first bevel gear 4a3 is arranged on the side of the connecting column 4a4 close to the first bevel gear 4a3, a handle 4a6 is arranged on the side of the connecting column 4a4 away from the second bevel gear 4a5, and a connecting hole for the threaded rod 4a2 to penetrate is opened in the support seat 2. Rapid and accurate adjustment of the movable plate 42 is achieved, the operation is simple and labor-saving, and the work efficiency is improved.

[0029] Example 2: Please refer to Figure 4-Figure 6 , and combined with the first embodiment, it is further obtained that the movable plate 42 is also provided with an auxiliary positioning mechanism 5 for positioning the workpiece, the auxiliary positioning mechanism 5 is provided with a fixed frame 51, the fixed frame 51 is provided at the top of the movable plate 42, at least three groups of connecting tubes 52 are provided in the fixed frame 51, a slide bar 53 is slidably provided in the connecting tube 52, a first connecting plate 54 is provided at the bottom end of the slide bar 53, a cushion 55 is provided at the bottom end of the first connecting plate 54, a first spring 56 is provided in the connecting tube 52, the top end of the first spring 56 is connected to the top end of the connecting tube 52, and the bottom end of the first spring 56 is connected to the top end of the slide bar 53. The stability and accuracy of the workpiece during the processing are ensured, and the processing error caused by the movement or offset of the workpiece is prevented.

[0030] Furthermore, a distance detection mechanism 6 for detecting the moving distance of the movable plate 42 is arranged on the outer side of the mounting frame 41, and a measuring scale 61, a second connecting plate 62, a signal receiver 64 and a control device 65 are arranged in the distance detection mechanism 6, the measuring scale 61 is arranged on the outer side of the mounting frame 41, the second connecting plate 62 is fixed to the side of the movable plate 42, a distance sensor 63 is arranged in the second connecting plate 62, the signal receiver 64 is arranged in the support seat 2, and the control device 65 is arranged at the top of the support seat 2. Real-time monitoring and control of the moving distance of the movable plate 42 is realized, and the accuracy and controllability of the processing are improved.

[0031] The utility model also comprises a tapping machine, comprising the above-mentioned distance-adjustable tapping mechanism.

[0032] In actual operation, when a workpiece needs to be tapped, the operation steps are as follows: first, place the workpiece to be processed in the placement groove 3. Then, turn the handle 4a6 to drive the connecting column 4a4 to rotate, thereby rotating the second bevel gear 4a5. This action will link the first bevel gear 4a3 to rotate, and then the threaded rod 4a2 will rotate under the limit of the mounting rod 4a1, driving the movable plate 42 to slide in the mounting frame 41, thereby adjusting the position of the tap head 44.

[0033] The moving position of the movable plate 42 can be observed by measuring the scale 61. At the same time, the distance sensor 63 (located in the second connecting plate 62) detects the distance between the movable plate 42 and the support seat 2, and transmits the information to the signal receiver 64. After processing, the information is fed back to the control device 65. When the tap head 44 reaches the preset processing position, the handle 4a6 stops rotating to lock the position of the movable plate 42.

[0034] During the descent of the movable plate 42, the first connecting plate 54 is also descended, and the soft pad 55 contacts the workpiece. As the movable plate 42 continues to descend, the slide bar 53 slides in the connecting tube 52, compressing the first spring 56. When the movable plate 42 stops descending, the potential energy of the first spring 56 is released, generating a thrust on the slide bar 53, so that the first connecting plate 54 and the soft pad 55 can position the workpiece, preventing the workpiece from shifting during the tapping process.

[0035] Subsequently, the driving motor 43 is turned on to rotate the tap head 44, and the movable plate 42 is controlled to descend to perform tapping on the workpiece. At the same time, the distance detection mechanism 6 detects the position of the movable plate 42 in real time.

[0036] After the tapping is completed, the handle 4a6 is rotated in the opposite direction, and the movable plate 42 is retracted through the linkage of the second bevel gear 4a5, the connecting column 4a4, the first bevel gear 4a3 and the threaded rod 4a2. At this time, the first connecting plate 54 and the cushion 55 release the positioning of the workpiece, and then the workpiece can be taken out.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
