[Effect] The outer case and the glass edge can be inserted and assembled on the device at the same time accurately and in a short time.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an assembling device for inserting and fixing a watch case and a glass rim.

[0002]

[Prior art]

 Conventionally, when the timepiece exterior case and the glass rim are inserted and fixed by using the caulking device shown in FIG. 3, the rim undercut portion (see FIG. 2 (b)) is pressed from inside the glass rim with a claw-shaped punch to cut the glass. The rim was inserted into the outer case and assembled.

[0003]

[Problems to be solved by the device]

 However, the method of pressing the undercut edge of the glass edge with a claw-like punch has a weak caulking force, and the waterproof test due to the edge clearance cannot be cleared. It was

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is to press the undercut portion, which is preliminarily provided on the inner side of the glass edge shown in FIG. I tried to press it strongly.

[0005]

[Action]

 This device can be activated by operating the lever of the mounting jig board by using a machine, and it is now possible to easily and simultaneously insert and assemble the watch exterior case and the glass rim.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a lever, which is elastically held on the upper portion of the apparatus and is pushed downward to operate, so that it engages with a micro switch 9 for machining cycle start to start machining. Is formed. Reference numeral 2 denotes a positioning jig, which is attached to the upper surface of the block 14 provided on the main body base 5, and the exterior case 3 is attached by a holding member. The main body base 5 is supported by the column 15 provided on the device base 16. Reference numeral 4 is an air chuck provided on the apparatus base 16 and reaches the positioning jig 2 through a hole in the main body base 5. Reference numeral 6 is a pressing piece, which is attached to a cylinder 7 provided on the upper part of the apparatus and is adapted to descend toward the positioning jig 2. Reference numeral 8 denotes a cylinder horizontally attached to the apparatus base, which engages with the air chuck 4 and rotates the air chuck 4 by an arbitrary angular position.

In FIGS. 2 and 3, reference numeral 11 denotes a glass edge, which is temporarily attached to the case 3 previously attached to the positioning jig 2 via the packing 10. Reference numeral 13 denotes a glass edge undercut portion, which is provided inside the glass edge 11 in advance. A plurality of rollers 12 are attached to the air chuck 4 and are held so that they can rotate about their respective axes. The roller 12 is formed with a tapered surface, and this tapered surface is engaged with the inside of the glass edge undercut portion 13 to exert a pushing force.

The operation will be described below. In FIG. 1 and FIG. 2, the timepiece exterior case 3 which is the work piece is timed by the positioning jig 2 provided on the assembly apparatus for the timepiece exterior case and the glass rim. The outer case 3, the packing 10, and the glass rim 11 are set in a state of being temporarily assembled in advance. The bottom of the glass cut-out diameter of the work piece is pressed by the pressing piece 6 from the upper surface so that there is no clearance in the outer case 3, the packing 10, and the glass edge 11. At the same time, the micro-switch 9 for starting the processing cycle is actuated to push out the cylinder 7 and fix the outer case 3, packing 10 and glass edge 11 from the top. Then, in this state, the roller 12 mounted on the air chuck 4 is inserted until it presses the glass edge undercut portion 13, then the air chuck body 4 is rotated, and the roller 12 is completely cut under the glass edge undercut. The 13 parts are pressed over a wide range while rotating.

The lever 1 also serves to activate the micro switch 9 for cycle start, and is structured so as not to be activated until the pressing piece 6 comes into contact with the inner diameter bottom surface of the glass edge 11, thereby ensuring safety. This series of operations has a structure that can be changed by programming with a sequencer (not shown). Therefore, after the completion of a series of operations, the origin is returned.

[0010]

[Effect of device]

 As described above, the present invention has an effect that the watch case and the glass rim can be assembled at the same time accurately and in a short time.
