[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0032] Combine the following Figure 1-Figure 4 The measuring device provided in the embodiment of the present utility model is described.

[0033] Specifically, the measuring device includes a support 1 , a first moving member 2 , a first position detection device and a second moving member 3 .

[0034] The support 1 is provided with a guide rail 7. For example, during use, the support 1 is arranged at the bottom, and the guide rail 7 is extended in the vertical direction. Optionally, the guide rail 7 is arranged as a guide column.

[0035] The first moving member 2 is arranged on the guide rail 7 in an adjustable position along the extending direction of the guide rail 7. The first moving member 2 is provided with a probe 5 for contacting the part to be measured.

[0036] The first position detection device is used to detect the position information of the first moving member 2 on the guide rail 7. For example, the first position detection device can be a displacement sensor.

[0037] The second moving member 3 is adjustably arranged on the guide rail 7 along the extending direction of the guide rail 7. The probe 5 is arranged on the side of the first moving member 2 facing the second moving member 3 so that the probe 5 can contact the second moving member 3.

[0038] refer to Figure 2As shown, by setting a second movable member 3 with adjustable position on the guide rail 7 of the support 1, when measuring the cantilever, the second movable member 3 can be brought into contact with the bottom surface of the cantilever, and then the first movable member 2 is moved to make the probe 5 of the first movable member 2 contact with the second movable member 3 to perform a zeroing operation. Then the first movable member 2 is moved to make the probe 5 contact with the top surface of the cantilever, and the position information of the first movable member 2 obtained by the first position detection device can be used to obtain the size of the cantilever in the extension direction of the guide rail 7, as shown in FIG.

Figure 2 As shown, there is a distance between the bottom surface of the cantilever and the bottom surface of the part, that is, the cantilever is "suspended", and the existing height measuring device cannot directly measure the size of the cantilever in the height direction.

[0039] In this way, by setting a second movable member 3 with adjustable position on the guide rail 7 of the support 1, the second movable member 3 can be abutted against the bottom surface of the cantilever member, so that the second movable member 3 forms a reference plane, and then the distance between the top surface of the cantilever member and the reference plane is measured by the probe 5 of the first movable member 2, thereby completing the measurement of the cantilever member.

[0040] Of course, the measuring device can also measure the height of the part by moving the first moving member 2. The measuring principle is the same as that of the height measuring device in the related art, so it will not be described in detail.

Optionally, the sliding direction of the first telescopic seat 202 is perpendicular to the extension direction of the guide rail 7. For example, during use, the extension direction of the guide rail 7 is in the vertical direction, and the sliding direction of the first telescopic seat 202 is in the horizontal direction. The probe 5 is arranged on the first telescopic seat 202.

[0042] The measuring device further comprises a second position detection device, which is used to detect the position information of the first telescopic seat 202 on the first sliding seat 201. Optionally, the second position detection device is configured as a displacement sensor.

Then the second moving member 3 is moved to make the probe 5 contact the side wall of the second side of the part, and the lateral dimension of the part can be obtained by the position information of the first telescopic seat 202 obtained by the second position detection device.

[0044] With such arrangement, the second movable member 3 can be abutted against the side wall of the first side of the part, so that the second movable member 3 forms a reference plane, and then the probe 5 of the first movable member 2 is used to measure the distance between the side wall of the second side of the part and the reference plane, thereby completing the measurement of the lateral dimension of the part.

[0050] In some embodiments provided by the utility model, the second sliding seat 301 is provided with a second through hole for the guide rail 7 to pass through, and the second through hole can slide and rotate relative to the guide rail 7. Such a configuration can not only enable the second moving member 3 to move along the guide rail 7, so that the cantilever members at different height positions can be detected, but also enable the second moving member 3 to rotate around the guide rail 7, so that the direction of the second moving member 3 can be adjusted, so that the second moving member 3 can be oriented to the position where the part is located, thereby improving the adaptability of the measuring device, or the second moving member 3 can be staggered with the first moving member 2, so that the first moving member 2 can measure the height of the part.

For example, during the measurement process, the probe 5 can be moved to the center position of the angle to be measured, and then the rotating member 4 can be rotated so that the measuring column 8 on the rotating member 4 abuts against the side wall of the first side of the angle to be measured, and a zeroing operation is performed. Then the rotating member 4 is rotated so that the measuring column 8 abuts against the side wall of the second side of the angle to be measured.
