[0003] The front measurement of the bezel usually involves high-precision detection of its size, shape and surface features, which is very important in watch manufacturing and quality control. The CMM three-dimensional measuring instrument is a commonly used high-precision measuring equipment suitable for such fine measurement tasks. Its working mode is roughly to first firmly fix the bezel on the CMM's measuring platform, start the CMM program, and let the probe automatically contact the bezel surface along the preset path to collect data points. The CMM will record the three-dimensional coordinates of each contact point. After the measurement is completed, the CMM software will analyze the data and generate a report to show whether the various dimensions of the bezel meet the design specifications. According to the measurement results, the quality of the bezel is evaluated to see if it meets the standards. The bezel that does not meet the specifications needs further analysis of the reasons and corresponding measures.

[0004] The existing bezel is basically fixed in position by a fixture. Although it can ensure that the bezel remains stationary during the measurement process, the route of the CMM three-dimensional measuring instrument probe is preset in advance. When the bezel is replaced on the fixture, it is difficult to ensure that the position of the bezel remains unchanged.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-7 A three-dimensional measurement auxiliary tooling for a bezel comprises a base 1 and a bezel 2, characterized in that a movable opening 101 is formed on the base 1, two positioning parts 201 arranged opposite to each other are formed on the bezel 2, and pre-positioning notches 202 are formed on the two positioning parts 201; a positioning component for positioning and placing the bezel 2 is provided between the base 1 and the bezel 2; a clamping component for clamping the bezel 2 is provided on the upper wall of the base 1; and a pre-positioning component for pre-positioning the bezel 2 is provided on the movable opening 101.

[0036] Specifically, refer to Figure 1-Figure 4 The positioning assembly includes a positioning plate 3 and a positioning notch 301; the positioning plate 3 is fixed to the upper wall of the base 1, the bezel 2 surrounds the positioning plate 3 inside, and the outer side of the positioning plate 3 is against the bezel 2; the positioning notch 301 is formed on the outer side of the positioning plate 3, and the positioning portion 201 is against the positioning notch 301.

[0037] When using the utility model, the bezel 2 is put on the outside of the positioning plate 3 from top to bottom, and the positioning portion 201 is aligned with the positioning notch 301. The bezel 2 is locked in position by the positioning portion 201 and the positioning notch 301 being abutted against each other. When the bezel 2 is placed, the positioning notch 301 is used to achieve rapid positioning and placement, and the position of each bezel 2 is the same, so there is no need to spend time repeatedly adjusting the position of the bezel 2. At the same time, the outer side surface of the positioning plate 3 abuts against the bezel 2 at multiple locations to further lock the position of the bezel 2.

[0038] Specifically, refer to Figure 1-Figure 3 and Figure 5The clamping assembly includes a clamping block 4, a clamping portion 401, a bottom block 402 and a hollow groove 102; the clamping block 4 is arranged at the top of the base 1, the clamping portion 401 is formed on the horizontal four sides of the clamping block 4, and the clamping portion 401 is at the top of the bezel 2; the bottom block 402 is formed on the lower wall of the clamping block 4, the hollow groove 102 is opened in the middle of the base 1, and the bottom block 402 is inserted into the hollow groove 102. In the preset route of the probe of the CMM three-dimensional measuring instrument, the clamping portion 401 arranged on the horizontal four sides will not affect the measurement of the probe.

[0039] After the bezel 2 is placed and positioned, the bottom block 402 at the bottom of the clamping block 4 is aligned with the hollow groove 102 and lowered. After the bottom block 402 is inserted into the hollow groove 102, the clamping parts 401 around it press the bezel 2 to prevent the bezel 2 from shaking and affecting the measurement accuracy. It should be noted that after the bottom block 402 is against the bottom surface of the hollow groove 102, the clamping part 401 is only in contact with the bezel 2, and most of the gravity of the clamping block 4 and the clamping part 401 themselves will not act on the bezel 2, so as to prevent the clamping block 4 and the clamping part 401 from deforming the bezel 2.

[0040] Specifically, refer to Figure 1-Figure 4 and Figure 6 The pre-positioning component includes a sleeve 5, a positioning rod 501, a reset spring 502 and a load-bearing bracket 503; the sleeve 5 is fixedly arranged on the inner bottom surface of the movable opening 101, the positioning rod 501 is slidably connected in the sleeve 5, and the positioning rod 501 is consistent with the arc radius of the pre-positioning notch 202; the reset spring 502 is connected between the ground inside the sleeve 5 and the positioning rod 501, the load-bearing bracket 503 is fixedly arranged on the upper wall surface of the positioning rod 501, and the load-bearing part of the load-bearing bracket 503 is located at the bottom of the clamping block 4, and the outside of the positioning rod 501 can be wrapped with a protective pad to prevent the positioning rod 501 from scratching the pre-positioning notch 202 when moving up and down.

[0041] Before putting the bezel 2 on the outside of the positioning plate 3 from top to bottom, the pre-positioning notch 202 on the positioning part 201 is abutted against the positioning rod 501, and then the hand controlling the bezel 2 slightly applies force in the direction of the positioning notch 301, and then moves the bezel 2 downward while applying force. At this time, since the two positioning parts 201 of the bezel 2 are arranged opposite to each other, and the positioning rod 501 is arranged opposite to the positioning notch 301, the bezel 2 is moved downward after the positioning rod 501 abuts against the pre-positioning notch 202, and the positioning part 201 on the other side will enter the inside of the positioning notch 301 and abut against it. Through the above operation, the placement position of the bezel 2 can be pre-positioned, so that the positioning part 201 can be quickly aligned with the positioning notch 301 and put down, thereby improving the efficiency of placing the bezel 2.

[0042] When the bezel 2 is placed and then the clamping block 4 is used to press the bezel 2, the load-bearing bracket 503 will be pressed down during the lowering of the clamping block 4, and the load-bearing bracket 503 will drive the positioning rod 501 to move downward and retract into the sliding sleeve 5, and squeeze the return spring 502 between the inner bottom surface of the sliding sleeve 5, so that the positioning rod 501 is separated from the pre-positioning notch 202. At the same time, the load-bearing bracket 503 and the positioning rod 501 are staggered and connected by the horizontal plate at the bottom, so as to achieve the effect of both the load-bearing bracket 503 and the positioning rod 501 being away from the bezel 2, avoiding the positioning rod 501 from affecting the measurement of the measuring probe. After the measurement is completed, the clamping block 4 is removed, and the return spring 502 that has been squeezed before uses elastic potential energy to lift the positioning rod 501, so as to facilitate the use of the next bezel 2.

[0043] Specifically, refer to Figure 1-Figure 3 and Figure 5 The hollow groove 102 is formed with a positioning bevel a103, and the bottom block 402 is formed with a positioning bevel b403 which matches the positioning bevel a103. Each time the clamping block 4 is lowered, the positioning bevel b403 formed on the bottom block 402 can be aligned with the positioning bevel a103 to ensure that the position of the clamping block 4 is consistent each time it is lowered, and the position of the clamping portion 401 pressing the bezel 2 is consistent each time, thereby avoiding affecting the measurement of the measuring probe.

[0044] Specifically, refer to Figure 1 , Figure 5 and Figure 7 The lower wall surface of the pressing part 401 is provided with an arc groove 404 with the same arc as the bezel 2, and the arc groove 404 is wrapped with a protective layer 405. When the pressing part 401 presses the bezel 2, the arc groove 404 on the lower wall is sleeved on the upper edge of the bezel 2, and the internal protective layer 405 is used to ensure that the bezel 2 will not be damaged. The protective layer 405 is made of soft material (such as rubber or silicone), which can effectively prevent the bezel from being damaged during the measurement process.

[0045] Specifically, refer to Figure 2 and Figure 5 A magnet 6 is fixed in the hollow groove 102, and an iron block 406 is embedded in the lower wall of the bottom block 402. After the clamping block 4 is below, the magnet 6 absorbs the iron block 406 to fix the position of the clamping block 4, further preventing the clamping block 4 from shaking up and down during the measurement process and causing damage to the bezel 2.

[0046] Specifically, refer to Figure 1-Figure 3 A plurality of measuring holes 7 distributed in an annular shape are provided on the base 1, and a plurality of arc-shaped notches matching the measuring holes 7 are formed on the positioning plate 3. After the bezel 2 is positioned and placed, the measuring probe measures the bezel according to a preset route. The measuring holes 7 are provided at the measuring points of the probe, and the arc-shaped notches formed on the positioning plate 3 match the measuring holes 7, so as to avoid affecting the probe measurement and also partially hinder the position of the positioning bezel 2.
