Embodiment Construction

[0016] See Figure 1~3 As shown, the screw locking depth control mechanism of the present invention includes a support base 4 , a switch mounting base 5 , a micro switch 6 and a control circuit 10 .

[0017] See figure 1 , 2 As shown, the support base 4 of the present invention includes a support base 4-2 and a top plate 4-1 for placing the workpiece 1. The support base 4-2 can be L-shaped, and the support base 4 is conveniently installed on the working surface by fasteners. On the stage, the workpiece 1 is limited by the top plate 4-1 and the screw 2 is installed. See figure 1 , 2 As shown, a notch is provided on the top plate 4-1 of the support seat 4 of the present invention, and the upper part of the guide rod 3 is arranged in the notch on the top plate 4-1 to reduce external influence on the guide rod 3 .

[0018] See figure 1 , 2 As shown, the micro switch 6 of the present invention is mounted on the switch mounting base 5, and the micro switch 6 can be mounted on...

Abstract

The invention relates to a screw locking depth control mechanism which comprises a support, a switch mounting base, a microswitch and a control circuit. The support comprises a support body and a top plate used for storing a workpiece. The microswitch is mounted on the switch mounting base which is mounted on the support body in a height-adjustable mode. The upper portion of the switch mounting base is provided with a guide rod base with a guide rod hole. A guide rod is arranged in the guide rod hole and can freely move. The bottom of the guide rod is connected with a drive rod of the microswitch. A screw mounted on the workpiece downwards presses the guide rod when being screwed, the microswitch is deenergized and outputs a deenergization signal to the control circuit after the screw is in place in depth, and the control circuit controls a pneumatic tool to stop working and automatically control the pneumatic tool to return to work in a set delay time after the control circuit is deenergized. The screw locking depth control mechanism is simple and reasonable in structure, convenient to machine and adjust and low in manufacturing and using cost, operation of an operator is convenient, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to a control mechanism for screw locking depth, which belongs to the technical field of screw assembly. Background technique [0002] With the rapid development of the manufacturing industry, there are higher requirements for product quality and efficiency. Many products need to be connected by screws during assembly. Some screws only need to be locked, while others have certain requirements for the locking depth of the screws according to the needs. When controlling the screw locking depth, one is to control the locking depth through manual visual inspection. Due to inaccurate manual visual inspection, the screw locking depth is inconsistent, which obviously does not meet the requirements. Not only is the operation more troublesome, but it will also affect Assembly quality. At present, the more advanced control method is to use the combination of sensor and programmable controller PLC to detect the depth of the screw lock throu...
