Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece tapping, in particular to an automatic tapping device for multi-size threads. Background Art

[0002] Traditional thread processing methods, such as manual tapping, desktop tapping machines or simple automated equipment, have the following problems in use:

[0003] Early manual tapping completely relied on the operator's technical proficiency and physical strength. It was not only labor-intensive but also inefficient, and could not meet the needs of mass production in modern industry. Even though primary automated equipment appeared later, they often had single functions and poor adaptability. When changing workpieces or thread standards of different specifications, a lot of manual adjustments and downtime were required, resulting in low production efficiency and increased costs. Manual operation made it difficult to achieve high precision and consistency in thread processing, and it was easy to cause problems such as thread size deviation, irregular tooth shape, and rough surface, which affected the quality and service life of the final product. The precision control of traditional equipment was relatively limited, especially in continuous mass production, it was difficult to ensure the uniform quality of the threads of each product. Faced with diversified product demands, traditional thread processing equipment could often only process thread specifications within a certain range. For variable workpiece sizes and threads of different standards (such as metric, imperial, special threads, etc.), special tools needed to be replaced or complex adjustments needed to be made, which reduced the flexibility and efficiency of processing.

[0004] Based on the above background, the utility model proposes a multi-size thread automatic tapping device to solve the above problems. Utility Model Content

[0007] The tapping assembly includes a base fixed on the side edge of the mounting plate, a machine base fixed on the upper side of the base, a transmission member arranged on the outer end of the machine base, a motor installed on the inner end of the transmission member, a kit connected to the output shaft of the machine base, a tapping rod assembled inside the kit, a positioning member movably arranged on the output shaft of the machine base, a positioning rod passing through the upper corner of the positioning member, and a fixing member used for installing and positioning the positioning rod.

[0008] The utility model is further configured that a mounting groove for assembling fasteners is arranged on the side of the chassis, and the chassis is fixed to the external processing table through the fasteners.

[0009] The utility model is further configured that a limiting hole is provided at the edge of the turntable, wherein the limiting hole matches with the telescopic end of the limiting cylinder, and the main body of the limiting cylinder is equidistantly fixed on the side surface of the mounting plate.

[0010] The utility model is further configured that a workpiece body is arranged inside the workpiece clamping sleeve, and a locking piece is arranged at the tail of the workpiece clamping sleeve.

[0011] The utility model is further configured such that the output shaft of the motor is matched with the output shaft inside the machine base through a transmission gear arranged inside the transmission member, and a fixing member is fixed to the end of the upper side surface of the machine base.

[0012] The utility model is further configured that the positioning member is a V-shaped structure, and a shaft sleeve is embedded in the lower end of the positioning member.

[0013] The utility model has the following beneficial effects:

[0014] 1. The tapping device supports the processing of threads of various sizes. By adjusting the transmission parts, tapping rods and positioning parts, it can quickly adapt to the needs of different workpiece sizes and thread specifications. There is no need to frequently replace equipment or tools, which enhances the flexibility of the production process.

[0015] 2. The integrated tapping components and automated tapping process significantly reduce manual intervention. The motor-driven tapping operation is not only fast but also highly stable, which is particularly suitable for batch production and continuous operation, greatly improving production efficiency. The highly integrated design simplifies the operation process of the equipment, and the workpiece clamping and tapping parameter adjustment are convenient, reducing the learning cost of operators. At the same time, the modular structure design facilitates daily maintenance and troubleshooting, reducing the difficulty and cost of maintenance.
