Description

Technical Field

[0001] The utility model relates to the technical field of tapping devices, in particular to a tapping device for milling cutter processing. Background Art

[0002] The tapping device used for milling cutter processing usually refers to a tapping machine, also known as a tapping machine, which is a special machine tool used to cut internal threads in threaded holes. It uses a rotating milling cutter to create threads or other thread types on the surface of the workpiece.

[0003] A tapping machine usually has a rotating spindle, guide rails and a transmission system, and a drill drives the milling cutter to rotate. However, a large amount of debris will be generated during the milling process. The debris splashed to the outside is not only difficult to clean, but also splashed to the workers and caused physical harm. For this reason, we propose a tapping device for milling cutter processing to solve the existing problem. Utility Model Content

The upper end of the travel ring 12 is rotatably mounted with a screw 11 that is threadedly mounted with the support plate 2. A torsion ring 10 is provided on the upper end of the screw 11. A sliding sleeve 26 is embedded in the travel ring 12, and a guide rod 28 that is slidably inserted into the interior of the sliding sleeve 26 is provided on the upper end of the support ring 3. The outer wall of the mounting cylinder 9 is sleeved with a fixing ring 18 and a threaded ring 25 from top to bottom, and the outer wall of the threaded ring 25 is threaded. Equipped with a threaded sleeve 14, the outer wall of the threaded sleeve 14 is provided with a rotating rod 15 distributed in an annular array, the outer wall of the tool 8 is provided with a positioning hole 24 distributed in an annular array, and a positioning rod 23 with one end inserted into the positioning hole 24 is slidably installed inside the mounting cylinder 9. The outer side of the positioning rod 23 is sleeved with a spring 27 with two ends respectively connected to the positioning rod 23 and the mounting cylinder 9. The inner wall of the lower end of the threaded sleeve 14 is provided with a protrusion 7 distributed in an annular array and with an outer wall thickness gradually increasing. The protrusion 7 corresponds to the positioning rod 23. , a guide ring 16 is sleeved on the outer wall of the upper end of the threaded sleeve 14, a connecting ring 19 is provided above the fixed ring 18 and sleeved on the outer side of the mounting tube 9, a spring 17 is provided at the lower end of the connecting ring 19 and is connected to the fixed ring 18 and distributed in a ring array, a plug rod 20 is slidably inserted into the interior of the fixed ring 18, the lower end of which is inserted into the interior of the guide ring 16 and the upper end is connected to the connecting ring 19, a symmetrically distributed hydraulic rod 22 is provided inside the support plate 2, and a pull plate 21 is provided at the lower end of the hydraulic rod 22 and is located below the connecting ring 19;

[0022] Based on the implementation steps of Example 1: By means of the visual plate 5 sleeved on the outside of the tool 8, not only can the tapping condition of the workpiece surface be understood, but also the debris generated during the tapping process can be intercepted inside the visual plate 5, thereby preventing the debris from splashing and injuring the workers, thus playing a protective role for the workers. At the same time, the debris is prevented from splashing to the outside, the debris is intercepted, and the subsequent workers are prevented from cleaning the debris. In addition, the visual plate 5 can adapt to the fitting of irregular workpiece surfaces and adapt to the tapping of irregular workpiece surfaces.

[0023] At the same time, through the threaded installation of the threaded sleeve 14 and the threaded ring 25, when the threaded sleeve 14 rotates, multiple protrusions 7 are driven to rotate at the same time, and then multiple positioning rods 23 are squeezed to be inserted into the positioning holes 24, and the tool 8 is clamped and fixed at multiple points at the same time, realizing the convenient installation of the tool 8 and convenient replacement of the specifications of the tool 8.

[0024] Working principle: During the tapping process, the tool 8 is fitted with the output end of the motor 1. When the tapping specifications need to be adjusted, the tool 8 is replaced. At this time, the hydraulic rod 22 drives the pull plate 21 to lift, and the pulling force of the pull plate 21 acts on the connecting ring 19, thereby applying a pulling force to the spring 2 17, driving the insertion rod 20 to lift, and the lower end of the insertion rod 20 moves out of the guide ring 16, releasing the lock on the threaded sleeve 14. After the tool 8 is fitted with the output end of the motor 1, the gripping rotary rod 15 drives the threaded sleeve 14 to rotate, thereby driving the protrusion 7 An extrusion force is applied to the positioning rod 23, and the positioning rod 23 is squeezed by the extrusion protrusion 7, and one end is inserted into the positioning hole 24, locking the tool 8 at three points. It is worth noting that a plurality of sockets are provided inside the guide ring 16. After the guide ring 16 is rotated, there are still sockets inside the guide ring 16 corresponding to the plug rod 20. At this time, the hydraulic rod 22 drives the pull plate 21 to descend, and the elasticity of the spring 17 pulls the connecting ring 19 down. The plug rod 20 is inserted into the guide ring 16, locking the threaded sleeve 14, so that the tool 8 is stable after replacement.

[0025] The motor 1 is installed on the moving mechanism of the tapping equipment. When the moving mechanism drives the motor 1 to descend, the gripping torsion ring 10 drives the screw 11 to rotate according to the thickness of the workpiece and the tapping depth. Because the travel ring 12 is slidably guided inside the sleeve 26 inside the support plate 2 through the guide rod 28, the rotational force of the screw 11 acts on the rotating part installed with the travel ring 12, and the longitudinal force acts on the travel ring 12 to adjust the height position of the travel ring 12. During the tapping process, the visual plate 5 descends and fits the surface of the workpiece. The situation of the tool 8 during processing can be understood through the visual plate 5. When the visual plate 5 is squeezed, it is elastically supported by the spring 13. When the visual plate 5 is squeezed, it is lifted, and the motor 1 drives the tool 8 and the mounting cylinder 9 to rotate, and tapping is pressurized at the position after the workpiece is positioned. During the processing, the visual plate 5 fits the surface of the workpiece to intercept the sputtered debris.
