Background

The watch case is an important component of a wristwatch and is generally of a frame-like structure, for example of circular or square shape. During the manufacture of the watch case, it is necessary to detect the structure of the watch case, such as the inside diameter of the glass fitting of the watch case, the distance between the lugs, the height of the glass fitting position, and the like.

For the detection of the watch case, the traditional method is to adopt manual detection, and workers use measuring tools (go gauge, no-go gauge and height gauge) to manually measure. The measurement accuracy of the measuring tool depends on the accuracy of manual operation, and the reliability of the measurement result is poor, for example, the watchcase is not flat during measurement, so that the measurement of the thickness of the watchcase is inaccurate. Moreover, some measuring tools need to measure through the surface of a clamping workpiece, so that the products are easily scratched, for example, a height gauge needs to clamp the upper end face and the lower end face of a watch case through calipers, so that the end faces of the watch case are easily scratched. Moreover, the manual detection is easy to cause operation fatigue, and the working efficiency is low.

Example one

As shown in fig. 1 to 8, a watchcase detection device 100 according to a first embodiment of the present invention is provided.

As shown in fig. 1, the wristwatch case detecting apparatus 100 includes: a positioning mechanism 10 and a measuring mechanism 20. As shown in fig. 5, the positioning mechanism 10 is used for carrying and fixing the watch case 200, and the measuring mechanism 20 is used for measuring a spatial three-dimensional coordinate of a probe point preset on the watch case 200, and calculating required physical parameters such as an inner diameter size of a glass fitting position of the watch case 200, a distance between the lugs 201, and a height of the glass fitting position by the probe point spatial three-dimensional coordinate.

Hereinafter, the above case detecting apparatus 100 will be further described with reference to fig. 2 to 8.

As shown in fig. 2, the positioning mechanism 10 includes: the device comprises a stage 11, a pull rod 12 penetrating the stage 11, and a first driver 13 connected with the pull rod 12. The stage 11 is provided with a plurality of outer support blocks 111 radiating outward with the tie rods 12 as the axis. The first driver 13 is used to drive the pull rod 12 to move to push the outer support block 111 to move outwards, so as to achieve the purpose of expanding the watch case 200 from inside to outside. As shown in fig. 5, in operation, the watch case 200 is fitted to the stage 11 with the outer side of the outer stay 111 facing the inner side of the watch case 200. Then, the first driver 13 drives the pull rod 12 to sink relative to the object stage 11, so as to push the outer supporting block 111 to move outwards, and force the outer side of the outer supporting block 111 to abut against the inner side of the watch case 200, so that the watch case 200 is expanded and fixed. In this embodiment, the wristwatch case 200 is circular, and accordingly, a plurality of outer brace pieces 111 are arranged in sequence to form a cylindrical structure. If the watch case 200 is of other shape, such as square frame shape, the shape and layout of the outer support 111 can be adjusted adaptively.

For example, in the present embodiment, the object stage 11 is provided with four external supporting blocks 111 radiating outward around the pull rod 12, the four external supporting blocks 111 constitute an open-type chuck, and when the watch case 200 is sleeved on the external supporting blocks 111, the external supporting blocks 111 are opened outward along with the sinking of the pull rod 12, so as to achieve the purpose of expanding and fixing the watch case 200.

As shown in fig. 4 and 6, the outer stay 111 is provided with a stopper 1111 protruding outward. The limiting portion 1111 is used for supporting the watch case 200 so that the watch case 200 is at a predetermined height position.

In some embodiments, the object stage 11 may further include an elastic cushion block sleeved on the outer supporting block 111, and when the outer supporting block 111 is expanded outward, the cushion block plays a role of buffering, so as to prevent the outer supporting block 111 from scratching the inner side of the watch case 200 due to an instant impact force. At the same time, the outer support block 111 can be made to abut against the inside of the watch case 200 more closely.

As shown in fig. 3 and 4, in the present embodiment, the pull rod 12 is a vertical rod, the top end of which is an action end, and the bottom end of which is a driving end and is connected to the first driver 13. As shown in fig. 4 and 6, the top end of the drawbar 12 is provided with a tapered ram 121. The inner side of the outer supporting block 111 is provided with an inclined surface corresponding to the conical pressure head 121. When the pull rod 12 is lowered relative to the object stage 11, the tapered ram 121 applies an outward force to the outer supporting block 111 along the inner slope of the outer supporting block 111, thereby forcing the outer supporting block 111 to expand outward.

As shown in fig. 2, in the present embodiment, the positioning mechanism 10 further includes: a first positioning block 14 and a second positioning block 15. The first positioning block 14 and the second positioning block 15 are disposed outside the stage 11 in axial symmetry with the tie bar 12 as an axis. The first positioning block 14 and the second positioning block 15 are used for locking the position of the lug 201 of the watch case 200 to prevent the watch case 200 from rotating. During operation, the first positioning block 14 and the second positioning block 15 can prevent the watch case 200 from rotating, and the positioning precision of the watch case 200 is improved.

In this embodiment, as shown in fig. 5, in operation, the first positioning block 14 and the second positioning block 15 are inserted between two adjacent lugs 201 of the watch case 200, so that the watch case 200 is positioned to prevent the watch case 200 from rotating.

Further, as shown in fig. 7, the first positioning block 14 and the second positioning block 15 are each provided with an inward recessed portion 141 for avoiding the probe 221. When the distance between two adjacent lugs 201 is detected, the concave parts 141 on the first positioning block 14 and the second positioning block 15 can avoid the probes 221, so that the probes 221 can smoothly contact the probe points on the inner sides of the lugs 201.

In other embodiments, the first positioning block 14 and the second positioning block 15 may also fix the watch case 200 by clamping the outer sides of the lugs 201, for example, the first positioning block 14 and the second positioning block 15 are respectively provided with a positioning slot for inserting two adjacent lugs 201 at the same time, and the outer sides of the two lugs 201 are clamped by the inner sides of the positioning slots, so as to achieve the purpose of positioning.

Further, in some embodiments, the first positioning block 14 and the second positioning block 15 may also be slidably disposed on the outer side of the stage 11, and the positions of the first positioning block 14 and the second positioning block 15 may be adjusted by sliding, so that the watch case 200 with more sizes may be suitable. In addition, the first positioning block 14 and the second positioning block 15 may also be provided with a profiling structure, which may be more fitted to the shape of the lug 201 of the watch case 200, and may be detachably mounted, so as to improve the flexibility of the positioning mechanism 10.

As shown in fig. 2, in the present embodiment, the first actuator 13 is an air cylinder, and a piston rod of the air cylinder is connected to the driving end of the pull rod 12. In other embodiments, the first drive 13 can also be a drive in the form of an electric motor or an electromagnet.

As shown in fig. 8, the measurement mechanism 20 includes: a space moving unit 21 and a probe 22 mounted on the space moving unit 21. The probe 22 is provided with a probe 221 for contacting the watch case 200. The probe 22 is moved to the positioning mechanism 10 by the space moving unit 21, and contacts the surface of the watch case 200 by the probe 221 to detect the watch case 200.

The space moving unit 21 only needs to be able to drive the probe 22 to move in three dimensions, and therefore, the space moving unit 21 can be implemented in various ways.

For example, as shown in fig. 8, in the present embodiment, the space moving unit 21 includes: the device comprises a support frame 211, a first translation base 212 arranged on the support frame 211 in a sliding manner, a second driver 213 connected with the first translation base 212, a second translation base 214 arranged on the first translation base 212 in a sliding manner, a third driver 215 connected with the second translation base 214, a lifting base 216 arranged on the second translation base 214 in a sliding manner, and a fourth driver 217 connected with the lifting base 216. The probe 22 is mounted on a lift block 216. Movement of the probe 22 in three dimensions of space is achieved by the first translation stage 212, the second translation stage 214, and the elevator stage 216.

Further, in this embodiment, the second driver 213 is a motor, and is connected to the first translation base 212 through a screw rod disposed in the X direction and a nut sleeved on the screw rod. The third driver 215 is a motor and is connected to the second translation base 214 through a screw rod arranged in the Y direction and a nut sleeved on the screw rod. The third driver 215 is a motor and is connected with the lifting seat 216 through a screw rod arranged in the Z direction and a nut sleeved with the screw rod.

For another example, in other embodiments, the spatial movement unit 21 may include: a multi-axis robot. The probe 22 is mounted on the implement end of the multi-axis robot. The probe 22 is moved by the multi-axis robot so that the probe 22 can contact a probe point on the case 200.

Description of the working principle:

after the watch case 200 is placed on the stage of the positioning mechanism 10, the first driver 13 drives the pull rod 12 to sink, so that the outer supporting block 111 moves outwards to tension and fix the watch case 200. Then, the space moving unit 21 drives the probe 22 to move, so that the probes 221 of the probe 22 contact the points to be measured one by one, the probe 22 records data and transmits the data to the console of the machine tool (a controller with the same function may also be arranged in the measuring mechanism 20), the size of the watch case 200 is calculated through the console of the machine tool, and then the current detection result and the product yield are obtained. The movement track of the probe 22 can be preset on the console of the machine tool, and the worker only needs to put the watch case 200 in and then start the detection.

The above-described wristwatch case detecting apparatus 100, in operation, places the wristwatch case 200 in the positioning mechanism 10 so that the wristwatch case 200 is measured in a preset posture. Then, the space moving unit 21 of the measuring mechanism 20 drives the probe 22 to move to the positioning mechanism 10, the probe 221 on the probe 22 detects the preset probe point on the watch case 200, and the coordinate of the preset probe point on the watch case 200 in three-dimensional space is obtained in a point contact manner, so that the detection of the watch case 200 is improved from the traditional manual cooperation with a measuring tool to the automatic measurement. Through the design, the positioning mechanism 10 is used for fixing the watch case 200, and then the probe 221 on the probe 22 of the measuring mechanism 20 is used for probing the spatial three-dimensional coordinates of each probe point of the watch case 200 in a point contact manner, so that the collision scratch caused by the adoption of a measuring tool is avoided, the automatic measurement is realized, the working efficiency is improved, and the reliability of the detection result is high.
