Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a component assembling device for simultaneously assembling composite components coaxially rotatably and integrally assembled into predetermined positions.

BACKGROUND TECHNOLOGY Conventionally, a water faucet has been composed of many parts, including a tap rod to which a handle is fixed, a seal holder inserted into the rod, and a body into which these parts are assembled, and the structure has become complicated. Not only is there,
It is necessary to assemble a composite part consisting of a stopper rod that is screwed into the inside of the body and a seal holder that is screwed onto the outside of the body. This is the current situation. First, the operator attaches the packing to the packing holder, which has a threaded portion that engages with the outer periphery of the packing receiver on the body. Thereafter, the operator inserts a stopper rod having a threaded portion that engages with the inside of the body into the hole in the center of the seal holder, and then fixes a handle to the tip of the stopper rod. Further, while rotating the handle, the operator screws the stopper rod into the inside of the seal holder in the body, and at the same time screws the seal holder onto the outer periphery of the seal holder using a tool such as a hex wrench.

Problems that the invention aims to solve: Therefore, since the assembly of the water supply system is done manually, the work efficiency is very poor and the cost of assembly is high, so there is a demand for automation of this assembly work. ing.

Means for Solving the Problems The present invention was devised in response to the above-mentioned request, and includes a box bit that rotates in response to rotation from a rotational drive source and is arranged so as to be movable back and forth, and a box bit that contains the box bit. The chuck sleeve is arranged so that it can rotate freely. The chuck sleeve is configured to be rotated by a separate rotational drive source. Further, a chuck pawl is attached to the tip of the chuck sleeve so as to be openable and closable, and the chuck pawl is configured to rotate together with the chuck sleeve. The chuck pawl is configured to open and close in front of the box bit by the operation of a cylinder, and is configured to clamp a component held by the box bit. Further, the chuck claw is biased by a spring so that its tip is always open. On the other hand, a guide sleeve is disposed between the box bit and the chuck sleeve, and one end of the chuck claw is in contact with the outer periphery of the guide sleeve.
Further, a rod of a cylinder is connected to the guide sleeve, and the chuck pawl is configured to open and close as the guide sleeve slides.

Function A first part having a threaded part that threads into the inside of the workpiece and a second part having a threaded part that threads into the outside of the workpiece are assembled together, and each part is held rotatably on the same axis. When a composite part is to be assembled inside or outside a predetermined workpiece, an operator places the workpiece on a workpiece holder (not shown) and inserts the first part into the drive hole of the box bit. Thereafter, the cylinder operates and the tip of the chuck claw closes. When the chuck pawl closes and clamps the second component, the rotary drive source and another rotary drive source are activated, and the box bit and chuck sleeve begin to rotate, respectively. Therefore, while the first part is screwed into the inside of the workpiece, the second part is screwed into the outer periphery of the workpiece, making it possible to assemble the composite parts simultaneously.
