Description

Technical Field

[0001] The utility model relates to the technical field of bench tapping machines, and specifically relates to a bench tapping machine with a positioning mechanism. Background Art

[0002] A tapping machine is an efficient and precise metal processing equipment, mainly used for machining internal threads on metal workpieces. It adopts a rotary cutting method and uses a special tap to perform tapping operations on the workpiece, and can quickly and accurately complete the thread processing task. Tapping machines are widely used in the fields of mechanical manufacturing, mold manufacturing, automotive parts production, etc., and are one of the indispensable important equipment in modern manufacturing.

[0003] Although the existing technology meets the user's usage requirements to a certain extent, there are still certain defects in the usage process. The specific problems are as follows: Although the existing tapping machines can perform simple clamping and positioning on workpieces, they cannot achieve multi-directional processing during the clamping process, which greatly limits the flexibility and scope of processing. Because thread processing can only be carried out at fixed positions, it may lead to low efficiency when processing large or irregularly shaped workpieces, and even some specific processing requirements cannot be completed. In addition, the inability to perform multi-directional processing may also increase the working difficulty of operators, and additional adjustments or auxiliary tools are required to complete the comprehensive thread processing task, thereby increasing production costs and time.

[0004] In order to solve the above problems, we made improvements and proposed a bench tapping machine with a positioning mechanism. Content of the Utility Model

[0023] Specifically, vertical plates 8 are fixedly connected to both the front side and the back side of the top of the movable plate 7. An air cylinder 9 is fixedly connected to the outer side of the vertical plate 8. The output end of the air cylinder 9 penetrates to the inner side of the vertical plate 8, and the output end of the air cylinder 9 is fixedly connected to a clamping plate 19. An anti-slip pad 20 is adhered to the inner side of the clamping plate 19. A transverse chute 15 is opened at the bottom of the inner cavity of the adjusting box 6.
