Referring to fig. 1-4, the utility model discloses a swing plate fixing clamp for watch assembly, which is used for providing an assembly operation place in the assembly process of a hairspring, a balance wheel, an external pile and a swing plate of a watch, and respectively positioning the balance wheel and the swing plate so as to enable the components to be aligned quickly and accurately, reduce the assembly difficulty of the components and avoid the problem of damage of the components caused by shaking of the components in the assembly process. Specifically, the swing clamp plate fixing clamp of the present embodiment includes a base 100, a first positioning assembly, a positioning pin 200, and a second positioning assembly, where the base 100 is used for providing support for other components, and a placement groove 110 is formed at the top of the base 100. Preferably, the cross section of the placing groove 110 is adapted to the shape of the lower surface of the swing clamp 10, and the lower part of the swing clamp 10 is overlapped on the notch edge of the placing groove 110. The placement groove 110 penetrates through one side surface of the base 100 and forms a clearance gap 120 on the side surface of the base 100, the placement groove 110 penetrates through the top surface and the bottom surface of the base 100, the clearance gap 120 penetrates through the top surface, the bottom surface and one side surface of the base 100, and the placement groove 110 comprises an arc part adjacent to the clearance gap 120 and a strip part facing away from the clearance gap 120 and communicated with the arc part. In this embodiment, by providing the clearance gap 120, after the balance plate 10, the outer stake 20, the balance spring and the balance wheel 30 are assembled, it is convenient to insert a finger from the clearance gap 120 into the placement groove 110 and grasp the assembly, thereby removing the assembly.
The first positioning component comprises two swing clamp plate positioning columns 300 which are oppositely arranged at two sides of the placing groove 110 and fixedly connected with the top of the base 100, the swing clamp plate positioning columns 300 are adjacent to the avoidance gap 120, and a swing clamp plate positioning table 310 is formed between the swing clamp plate positioning columns 300 and the edge of the notch of the placing groove 110.

In this embodiment, the positioning pin 200 is used for initially positioning the swing clamp plate 10, so as to prevent the swing clamp plate 10 from being pulled out by a horizontal acting force after being embedded into the clamp; the swing clamp positioning post 300 is spaced from the edge of the notch of the placement groove 110 by a predetermined distance to form a swing clamp positioning table 310, and the swing clamp positioning table 310 is used for supporting one side of the swing clamp 10 adjacent to the clearance gap 120, so as to prevent the upper part of the swing clamp 10 from falling into the placement groove 110, and further ensure the normal operation of the assembly operation. The swing clamp plate positioning column 300 is used for limiting the swing of the swing clamp plate 10 and preventing the swing clamp plate 10 from swinging on the clamp, so that the limit of the swing clamp plate 10 in the horizontal direction is realized through the joint constraint of the positioning pin 200 and the swing clamp plate positioning column 300.
The second positioning assembly includes at least two balance positioning columns 400 spaced apart along the circular arc path at the edge of the notch of the placement groove 110, and a balance limiting platform 410 is disposed on one side of the balance positioning column 400 adjacent to the placement groove 110, and it can also be understood that the vertical section of the balance positioning column 400 has an L-shaped structure, so as to limit the position of the outer edge of the balance 30 while supporting the balance 30, and prevent the balance 30 from translating on the fixture. In this embodiment, the height of the swing clamp positioning post 300 is smaller than or equal to the height of the balance wheel limiting platform 410, so as to avoid the damage to the balance wheel 30 caused by the lifting of the swing clamp positioning post 300 and the interference to the rotation of the balance wheel 30 during the position adjustment caused by the insertion of the swing clamp positioning post 300 into the through hole of the balance wheel 30. It is emphasized that in this embodiment, the upper surface of balance limiting platform 410 is planar so as to maintain balance 30 level while defining the height position of balance 30.
In the conventional balance spring assembly and stud bonding process, the general procedure is to bond the stud to the second end of the balance spring and then to mount the bonded stud and balance spring to the balance plate and balance respectively, whereas in this embodiment, the balance spring is prevented from being damaged when it is mounted to the balance plate 10 by changing the assembly sequence by combining the balance 30 and balance spring, and stud 20 and balance plate 10, respectively, and finally bonding the second end of the balance spring to the stud, and completing the assembly of the entire balance plate component when the bonding of the balance spring to stud 20 is completed. In the assembly process, the swing clamp plate 10 can be inverted in the clamp, the lower part of the swing clamp plate 10 is abutted against the edge of the notch of the placing groove 110, the swing clamp plate 10 is fixed in the clamp through the positioning pin 200 and the two swing clamp plate positioning columns 300, the outer piles 20 can be pushed into the quick and slow clamps of the swing clamp plate 10 after the swing clamp plate 10 is fixed, the outer piles 20 can be pushed into the quick and slow clamps of the swing clamp plate 10 in advance, and then the swing clamp plate 10 is positioned. After the balance spring is fixed to balance wheel 30, the balance spring balance wheel assembly is placed together on balance plate 10, and a plurality of balance wheel positioning columns 400 together position balance wheel 30, and balance wheel limiting platform 410 on balance wheel positioning columns 400 controls balance wheel 30 at an appropriate height. At this point, nudging balance 30 causes balance 30 to rotate and the second end of the hairspring enters the appropriate position between the arms of the stud to bond the hairspring to stud 20.
