Description

Technical Field

[0001] This utility model belongs to the field of mechanical watch testing instruments, and specifically relates to a microphone pickup testing device for a mechanical watch calibrator. Background Technology

[0002] Currently, the test clamps used in mechanical watch testing instruments on the market mainly consist of a left clamp and a right clamp. The contact surfaces of the left and right clamps with the two sides of the mechanical watch under test are flat surfaces. In particular, the contact surface between the watch crown and the left or right clamp is completely flat. If the watch crown is placed off-center from the flat surface, the watch is held by the sliding button, which makes it extremely easy for it to slip during the test. This can lead to test failure or, in severe cases, the mechanical watch under test may slip off the clamping platform of the test clamp, causing accidental damage. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a mechanical watch calibrator microphone pickup test device with a stable testing process and a wide range of applicable tests.

[0004] To achieve the above objectives, this utility model provides a microphone pickup and testing device for a mechanical watch calibrator, which includes a supporting base, a housing connected to the end of the supporting base, a top cover on the top of the housing, a side cover on the side of the housing, a piezoelectric ceramic transducer disposed inside the housing, and a clamping structure on the top cover that contacts the piezoelectric ceramic transducer on one side.

[0005] The clamping structure includes a fixed clamp provided between the side of the housing and the side cover, and a sliding clamp provided on the top cover that cooperates with the fixed clamp to clamp the bare movement 07 or mechanical watch.

[0006] The fixing clamp includes a limiting support foot provided between the housing and the side cover, an extension block provided on the limiting support foot extending to contact the piezoelectric ceramic transducer, an arc-shaped top plate provided on the top of the limiting support foot extending to the outside of the side cover and bending towards the top cover, and a first recessed platform provided on the top of the arc-shaped top plate.

[0007] The sliding clamp includes a horizontal slot on the top cover, an insert block embedded in the horizontal slot, a clamping block on the top cover that is integrally connected to the insert block and cooperates with the arc-shaped top plate to clamp the bare movement or mechanical watch, and a second recess on the clamping block corresponding to the position of the first recess.

[0008] In some implementations, the limiting support foot is an "open" shaped bracket.

[0009] In some implementations, the extension block is an L-shaped extension block, and its end contacts the piezoelectric ceramic transducer.

[0010] In some embodiments, a limiting groove is provided on the limiting support foot, and a limiting block is provided on the side cover corresponding to the limiting groove, which is locked in the limiting groove.

[0011] In some implementations, the bending angle of the curved top plate is 11°.

[0012] In some implementations, the radius of curvature on the curved top plate is 16.8 mm.

[0013] The beneficial effects of this utility model are that it has a stable testing process and a wide range of applicable tests. Because the surface in contact with the crown of the mechanical watch is an arc-shaped top plate, that is, it is designed as an arc-shaped contact; and the arc-shaped top plate is bent towards the top cover to form an upward angle design, which makes the mechanical watch and movement clamping more stable and reliable, and less likely to slip off and cause measurement failure or damage to the watch movement. For example, the arc radius of the arc surface on the arc-shaped top plate is 16.8 mm, which is comparable to the radius of most watch movements. No matter how slightly the angle of the movement is offset, the axis of the movement crown and the arc surface (8) of the contact surface of the watch crown are basically kept perpendicular, and slippage is not easily generated. The bending angle of the arc-shaped top plate is 11°, which effectively suppresses the outward slippage of the watch crown and increases the clamping stability. Therefore, the purpose of stable testing process is achieved. Furthermore, because the fixed clip and sliding clip in the clamping structure can be used for testing mechanical watches or bare movements, it has the characteristics of adapting to different conditions for repair and testing, and achieves the effect of a wide range of applicable tests.

[0030] The utility model will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1-16As shown, a microphone pickup and testing device for a mechanical watch calibrator includes a supporting base 01, a housing 02 connected to the end of the supporting base 01, a top cover 03 on the top of the housing 02, a side cover 04 on the side of the housing 02, a piezoelectric ceramic transducer 05 disposed inside the housing 02, and a clamping structure 06 on the top cover 03 with one side in contact with the piezoelectric ceramic transducer 05. The clamping structure 06 includes a fixing clip 61 disposed between the side of the housing 02 and the side cover 04, and a sliding clip 62 on the top cover 03 that cooperates with the fixing clip 61 to clamp a bare movement 07 or a mechanical watch 08. The fixing clamp 61 includes a limiting support foot 611 disposed between the receiving box 02 and the side cover 04, an extension block 612 on the limiting support foot 611 extending to contact the piezoelectric ceramic transducer 05, an arc-shaped top plate 613 on the top of the limiting support foot 611 extending beyond the side cover 04 and bending towards the top cover 03, and a first recess 614 on the top of the arc-shaped top plate 613. The aforementioned arc-shaped top plate 613 is bent towards the top cover 03 to form an upward angle design. The limiting support foot 611, extension block 612, arc-shaped top plate 613 and first recess 614 in the fixing clamp 61 are integrally stamped, bent and cut, and all functional parts of the components are rigidly connected with no movable parts, thereby ensuring the best effect of vibration energy transmission during testing. The sliding clamp 62 includes a horizontal slot 621 on the top cover 03, an insert block 622 embedded in the horizontal slot 621, a clamping block 623 on the top cover 03 integrally connected to the insert block 622 and cooperating with the arc-shaped top plate 613 to clamp the bare movement 07 or mechanical watch 08, and a second recess 624 on the clamping block 623 corresponding to the first recess 614. The limiting support foot 611 is an "open" shaped bracket. In addition, a silicone shockproof sleeve is fitted onto the limiting support to effectively isolate external interference vibrations. The extension block 612 is an L-shaped extension block 612, and its end contacts the piezoelectric ceramic transducer 05. The limiting support foot 611 is provided with a limiting groove 615. A limiting block 616 is provided on the side cover 04 corresponding to the limiting groove 615 and is engaged in the limiting groove 615. The radius of the curved surface on the top plate 613 is 16.8 mm, a design comparable to that of most watch movements. Regardless of slight deviations in the movement's orientation, the axis of the movement crown and the curved surface of the crown contact surface remain essentially perpendicular, preventing slippage. The bending angle of the top plate 613 is 11°, effectively suppressing outward slippage of the crown and increasing clamping stability.

[0032] Working principle

[0033] Because the extension block 612 on the limiting support foot 611 is in contact with the piezoelectric ceramic transducer 05, the movement vibration signal can be effectively transmitted to the piezoelectric ceramic transducer 05. In the test scenario, when the mechanical watch 08 is running, the escapement mechanism swings back and forth, generating a vibration signal. The vibration signal is generated by the top plate 613 of the curved surface where the crown of the watch contacts the curved surface, and is converged by the clamping structure 06 to the extension block 612 in contact with the piezoelectric ceramic transducer 05, and then transmitted to the piezoelectric ceramic transducer 05. Thus, the mechanical vibration signal is converted into a voltage signal, completing the signal acquisition.

[0034] In the bare movement 07 clamping test scenario, simply place the bare movement 07 between the corresponding first recess 614 and second recess 624. This scenario is a test operation for real-time monitoring of the repair status and adjustment results during watch repair. Repair technicians can intuitively repair and adjust the movement and monitor the output results in real time, shortening repair time, reducing repair difficulty, and improving repair efficiency.

[0035] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
