Positive and negative rotation tap chuck

Abstract

The invention discloses a positive and negative rotation tap chuck, and relates to the field of car assembling. The positive and negative rotation tap chuck comprises a transmission mechanism and a positioning mechanism, the transmission mechanism comprises a taper handle, transition gears and a chuck body, a driving gear is fixed to one end of the taper handle through a positioning pin, the positioning pin extends to the end of the taper handle, the tail of the chuck body is sleeved with a driven gear in a non-contact mode, a driving pin is arranged on the driven gear to extend to the end face, a square key is arranged at the tail of the chuck in the radial direction and extends to the circumferential face of the chuck body, the taper handle and the chick body are coaxial, the square key is located between the taper handle and the chuck body, the driving gear is in gear fit with the driven gear through the two transition gears, a positioning mechanism comprises a tap box, the transmission mechanism is located inside the tap box, the taper handle and the chuck head extend to the exterior of the tap box, positive-phase backward tapping is achieved at the same time, the structure is simple, operation is easy, and large torque can be borne.

Description

Technical field [0001] The invention relates to the field of assembly, in particular to a positive and negative tap chuck. Background technique [0002] The automobile is an organic combination of various parts, so the last process of automobile production must be assembly. Otherwise, the parts cannot be combined and coordinated with each other and perform their due functions. The so-called assembly refers to the assembly of various parts Or the assembly is connected and combined into a complete product production process according to the specified technical and quality requirements. A process is involved in the production process: tapping, tapping is used to process the internal threads of parts, and its tool is called tapping. [0003] In the process of automobile assembly, not only does the tapping need to be rotated forward, if the tapping encounters resistance, it is easy to cause frequent reversal of the tapping machine spindle. Therefore, reverse tapping is required at the ...

Problems solved by technology

[0003] During the automobile assembly process, not only the forward rotation is required for tapping, but if the tapping is blocked, it is easy to cause the spindle of the tapping machine tool to reverse frequently. Therefore, reverse tapping is required at the same time. At present, the solution for reverse tapping mostly uses friction In reverse tapping, the use of friction tapping must maintain a large axial pressure, which is usually provided manually. On the one hand, the torque required for transmission tapping is limited; on the other hand, the operation is laborious during the whole process of tapping, and the device more wear and tear
