Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
The utility model embodiment provides a kind of thread positioning mechanism, and as Figure 1-3, it includes drive component 1, positioning
Component 2 and thread forming component 3, drive component 1 drive thread forming component 3 to form screw thread, positioning component 2 on product
Be equipped with the positioning for realizing the starting point of thread forming component 3 with thread forming component 3, positioning component 2 include alignment pin 21 with
And spring 22, the spring 22 are against the rear end of alignment pin 21, the thread forming component 3 includes gear 31, the gear 31
Provided circumferentially about to have gear, the gear coordinates the positioning for realizing screw thread with alignment pin 21, and so, drive component 1 drives screw thread
Molding assembly 3 forms screw thread on product, and positioning component 2 is equipped with thread forming component 3, is realized by alignment pin 21
Positioning to screw thread starting point.
The gear is groove, and two faces of inside grooves are respectively inclined-plane and vertical plane, and so, alignment pin 21 is stuck in
At the gear of gear 31, dynamic model is set accurately to return to initial position when using next time.
Thread forming component 3 is at least provided with one, so, can complete the thread forming of multiple products simultaneously.
Drive component 1 includes motor, belt pulley 11, belt 12 and turn wheel 13, output shaft and the belt pulley 11 of motor
Connection, belt pulley 11 are set in one end of belt 12, and the other end of belt 12 is arranged turn wheel 13, and turn wheel 13 is nibbled with gear 31
Close, so, drive component 1 is rotated with moving gear 31, and power is provided to thread forming component 3.
The length of alignment pin 21 is not less than the length of gear, and this ensures that, the gear that alignment pin can be stuck in gear 31
