Abstract

Technical Field
[0001] This utility model relates to the technical field of thread tapping machines, specifically an automatic tapping machine for plastic pipes. Background Technology
[0002] Tapping plastic pipes (i.e., machining threads) is mainly to achieve reliable sealing connections and meet the assembly needs of different application scenarios. Tapping is a key process for achieving standardized and modular assembly of plastic pipes, and is especially suitable for industrial scenarios that require frequent disassembly and replacement.
[0003] Plastic pipes are screwed onto metal / plastic joints via external or internal threads, replacing adhesive or heat fusion connections. This facilitates repeated disassembly and maintenance (such as water pipe repair and equipment cleaning). Currently, tapping plastic pipes mostly involves manual tapping using simple tools, resulting in low production efficiency and poor accuracy (uneven thread depth and skew). Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic tapping machine for plastic pipes to address the problems of low production efficiency and low precision caused by the prevalence of manual tapping in the prior art.
[0005] To achieve the above objectives, this utility model proposes an automatic tapping machine for plastic pipes, including a processing table. The processing table is provided with an internal thread processing area and an external thread processing area. A plurality of tapping motors are fixedly installed on the processing table.

Detailed Implementation
[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figure 1-4 As shown, an automatic tapping machine for plastic pipes includes a processing table 001. The processing table 001 is provided with an internal thread processing area and an external thread processing area. In this embodiment, both the internal thread processing area and the external thread processing area are provided with a set of processing structures. Each set of processing structures can simultaneously process one plastic pipe 004 to be processed. A tapping motor 002 is fixedly installed on the processing table 001. In this embodiment, the tapping motor 002 is a three-phase asynchronous motor, model YS-6314. Four tapping motors 002 are provided. The output shaft of the tapping motor 002 located in the external thread processing area is fixedly connected to a die head 005 via a coupling 003. The output shaft of the tapping motor 002 located in the internal thread processing area is fixedly connected to a spiral groove tap 006 via a coupling 003. Two sets of clamping components are provided on the processing table 001. 200. The clamping assembly 200 is used to limit the movement of the plastic tube 004 to be processed, and works in conjunction with the tapping motor 002 to tap the internal / external threads of the plastic tube 004. The clamping assembly 200 includes a limiting seat 202, in which a lower pressure plate 205 is fixedly disposed, and an upper pressure plate 203 is slidably disposed. Both the upper pressure plate 203 and the lower pressure plate 205 have limiting grooves 204. A second electric push rod 201 is fixedly disposed on the limiting seat 202. The output shaft of the second electric push rod 201 is fixedly connected to the upper pressure plate 203. When the plastic tube 004 to be processed is placed between the upper pressure plate 203 and the lower pressure plate 205, the second electric push rod 201 is activated, pushing the upper pressure plate 203 to slide and clamp the plastic tube 004 to be processed, thereby limiting the movement of the plastic tube 004.
[0024] To facilitate adjustment of the thread processing area of the plastic tube 004 to be processed, the processing table 001 is equipped with two sets of slide rails 007. A slider 008 is fixedly installed below the limiting seat 202, and the slider 008 is slidably connected to the slide rails 007. A connecting rod 011 is fixedly installed between one set of sliders 008 in the internal thread processing area and the external thread processing area, respectively. A pair of first electric push rods 012 are fixedly installed on the processing table 001, and the output shaft of the first electric push rod 012 is fixedly connected to the connecting rod 011. The plastic tube 004 to be processed is placed in the clamping assembly 200, with the end to be processed aligned with the tapping structure at the output end of the tapping motor 002. The clamping assembly 200 is activated to limit its movement. Then, the tapping motor 002 is activated to tap the internal / external threads of the plastic tube 004 to be processed. The first electric push rod 012 is activated, which drives the connecting rod 011 to move, thereby driving a pair of clamping assemblies in the internal thread processing area and the external thread processing area to move synchronously, thereby adjusting the tapping area and realizing the synchronous processing of the plastic tube 004 to be processed in the same area.
[0025] A stop 009 is fixedly provided at one end of the slide rail 007 near the first electric push rod 012. A baffle 010 is fixedly provided on several of the 009s. The baffle 010 enables the plastic tube 004 to be processed to be mounted. When the first electric push rod 012 is activated to drive the limiting seat 202 to slide, the unprocessed end of the plastic tube 004 to be processed will not be suspended in the air, but will slide on the baffle 010. At the same time, the baffle 010 can protect the first electric push rod 012.
[0026] Working principle:
[0027] In use, the plastic tube 004 to be processed is placed inside the clamping assembly 200, with the end to be processed aligned with the tapping structure at the output end of the tapping motor 002. The clamping assembly 200 is activated to limit its movement. Subsequently, the tapping motor 002 is activated to tap the internal / external threads of the plastic tube 004. The first electric push rod 012 is activated, driving the connecting rod 011 to move, thereby causing a pair of clamping assemblies in the internal thread processing area and the external thread processing area to move synchronously, thereby adjusting the tapping area and achieving synchronous processing of the plastic tube 004 in the same area.
