[0082] Specifically: the preliminarily installed left skeleton positioning component 2, quartz pendulum positioning component 3 and right skeleton positioning component 4 are coaxially placed, and the multiple third positioning pins 13 of the left skeleton positioning component 2 are sequentially passed through the multiple first through holes of the quartz pendulum positioning component 3 and are respectively connected with the corresponding multiple positioning holes 7.2 on the right skeleton positioning component 4; at this time, the multiple first magnets 11 on the left skeleton positioning component 2 and the multiple second magnets 12 on the right skeleton positioning component 4 are respectively adsorbed on both sides of the quartz pendulum positioning component 3, completing the quick guided installation of the left skeleton positioning component 2, the quartz pendulum positioning component 3 and the right skeleton positioning component 4; after installation, the left skeleton positioning component 2, the quartz pendulum positioning component 3 and the right skeleton positioning component 4 are on the same axis;

[0083] Pre-tightening pressure is applied to the left frame 1.2 and the right frame 1.3 respectively through the elastic positioning and pressure-applying mechanisms 5 on the left frame positioning component 2 and the right frame positioning component 4, so that the left frame 1.2 and the right frame 1.3 are tightly attached to the two sides of the quartz pendulum 1.1, ensuring the stable assembly of the left frame 1.2, the right frame 1.3 and the quartz pendulum 1.1, so as to ensure that stable pressure is maintained on both sides during transportation and curing.

[0084] Specifically: by tightening the elastic positioning pressure mechanism 5 on the left frame positioning component 2 and the right frame positioning component 4, the spring 5.2 in the elastic positioning pressure mechanism 5 is compressed, thereby pushing the positioning block 9 at its front end to move toward the quartz pendulum positioning component 3, so that the left frame 1.2 and the right frame 1.3 located on the positioning blocks 9 on both sides move toward the quartz pendulum 1.1, and maintain a certain pressure to clamp on both sides of the quartz pendulum 1.1;

[0085] In this process, since the setting of the first positioning pin 8.2 limits the circular motion of the positioning block 9, and the setting of the second positioning pin 9.4 limits the circular motion of the left frame 1.2, the angle of the left frame 1.2 can be fixed during assembly, thereby improving the accuracy of assembly and the symmetry of the central axis.

[0086] In the above embodiment, preferably, it further includes:

[0087] The assembled left frame positioning component 2, right frame positioning component 4 and quartz pendulum positioning component 3 are heated and cured;

[0088] After the heating and curing are completed, the left frame 1.2 and the right frame 1.3 are pushed out onto the frame mounting parts 9.3 of the left frame positioning assembly 2 and the right frame positioning assembly 4 by the pushing mechanism 6 to complete the assembly of the quartz ornament 1.

[0089] In this embodiment, the structure is stable, the design is reasonable, and the use is convenient. It can well solve the problems of inaccurate positioning and asymmetry between the two sides that occur during the assembly process of the quartz ornament 1, and is also compatible with the supporting use of subsequent automated equipment.

[0090] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
