Description

Technical Field

[0001] The utility model relates to the technical field of watch case detection, and more specifically to a simple device for watch case detection. Background Art

[0002] A watch, or wristwatch, is an instrument worn on the wrist for timing / displaying time. With the development of watch technology, smart watches have also been widely promoted. In addition to indicating time, smart watches should also have one or more functions such as reminders, navigation, calibration, monitoring, and interaction. The display methods include pointers, numbers, images, etc. People have also begun to have requirements for its appearance, so a variety of molding methods have been developed. However, after the watch shell is molded, workers need to test its appearance size, etc., which affects work efficiency.

[0003] Under the existing technology, when performing impact tests on plates used to produce watch cases, large-scale factories will use professional impact testing machines to conduct tests, but impact testing machines are expensive and large in size, which are not convenient for small-scale production. When conducting inspections, small-scale factories usually manually swing the pendulum for testing, but this operation can easily cause the plate to shift during impact, thereby affecting the accuracy of the inspection.

[0004] In view of this, we propose a simple device for case detection. Utility Model Content

[0012] Preferably, one end of the compression spring abuts against the upper end surface of the circular plate, the other end of the compression spring is spirally embedded in the middle of the engaging groove, and a buckle is installed at the top end of the impact hammer.

[0013] Preferably, a slider is installed at the bottom end of the two clamping mechanisms, a groove for the slider to slide is opened in the workbench, and a connecting ear is installed at the bottom end of the two sliders.

[0024] Two clamping plates 3 are symmetrically installed in the clamping mechanism 201, and arc plates 301 are constructed on the side of the two clamping plates 3 facing the center of the workbench 1. A groove for the clamping plate 3 to rotate is opened in the clamping mechanism 201; a limit block 203 for limiting the rotation of the clamping plate 3 is constructed in the clamping mechanism 201, and two tension springs 302 connecting the clamping plates 3 are symmetrically installed on the side of the clamping mechanism 201. The impact device 6 includes a support plate 601, and a cylinder 602 is installed on the side of the support plate 601 facing the workbench 1. An impact hammer 7 is elastically slidably installed in the cylinder 602, and an impact head 701 is installed at the bottom of the impact hammer 7. A screw cap 603 is spirally installed on the top of the cylinder 602, and the top of the impact hammer 7 passes through the screw cap 603 and extends out of the upper end surface of the screw cap 603. The impact hammer 7 is placed in the cylinder 602 and is configured with a circular plate 702 at the bottom end. In an embodiment of the utility model, the watch case is clamped by the arc grooves 202 and the clamping plates 3 on the two clamping mechanisms 201. By pulling the impact hammer 7, the spring 604 pushes the circular plate 702 to slide in the cylinder 602, and the impact head 701 is used to perform impact detection on the watch case, thereby solving the problem that the current watch case detection volume is large and not convenient for small-scale production, and the manual swing of the hammer will affect the detection accuracy.

[0025] In the embodiment of the utility model, a compression spring 604 is installed in the cylinder 602, and the compression spring 604 is placed on the outer edge surface of the impact hammer 7. A fitting groove 605 for the compression spring 604 to be spirally embedded is provided in the screw cover 603. One end of the compression spring 604 abuts against the upper end surface of the circular plate 702, and the other end of the compression spring 604 is spirally embedded in the middle of the fitting groove 605. A buckle is installed on the top of the impact hammer 7, and sliders 4 are installed at the bottom ends of the two clamping mechanisms 201. A groove for the sliders 4 to slide is provided in the workbench 1. The bottom ends of the two sliders 4 are installed with connecting ears 401, and the two connecting ears 401 are connected together by a long rod 5, and the outer edge surface of the long rod 5 is provided with two threaded grooves 501 which are respectively spirally connected to the two connecting ears 401, and the thread directions of the two threaded grooves 501 are opposite. A grip 502 is installed at one end of the long rod 5.

The arc groove 202 fits the side of the watch case, and the arc plates 301 on the sides of the two clamping plates 3 clamp and fix the watch case, so that the watch case is placed directly under the impact hammer 7, and then the impact hammer 7 is pulled, and the compression spring 604 is squeezed by the circular plate 702. After that, the impact hammer 7 is released and the circular plate 702 is pushed by the compression spring 604, and the impact head 701 hits the watch case for detection. When the rebound force decreases, the screw cover 603 is rotated and unscrewed, and the compression spring 604 embedded in the fitting groove 605 is spirally unscrewed for a section, thereby increasing the length of the compression spring 604 placed in the cylinder 602.
