[0032] Example 1

[0033] like Figure 1 As shown, this embodiment provides a device for detecting the tightening depth of fasteners on a magnet positioning plate, including a curved panel 1 that abuts against the surface of the magnet 200 and a depth gauge 8 for measuring the tightening depth of fasteners 300 on the pressure block 100.

[0034] In this embodiment, when it is necessary to detect the tightening depth of the fastener 300 on the pressure block 100, the depth of the fastener 300 is measured by the depth gauge 8 through the curved panel 1 abutting against the magnet 200.

[0035] Furthermore, such as Figures 1-2 As shown, the curvature of the curved panel 1 is the same as the curvature of the magnet 200 surface.

[0036] It should be noted that the same curvature of both ensures that the curved panel 1 can fit tightly against the surface of the magnet 200. In actual testing, the testing device is placed on the surface of the magnet 200, and the curved panel 1 fits perfectly against the magnet 200 as if it were custom-made, without any unstable situations such as shaking or lifting.

[0037] Example 2

[0038] like Figures 2-5 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0039] The magnetic steel positioning plate fastener screwing depth detection device further comprises an adjusting mechanism 400 for changing the position of the depth gauge 8 on the curved plate 1.

[0040] It should be noted that by setting the adjusting mechanism 400, the position of the depth gauge 8 on the curved plate 1 can be conveniently adjusted to ensure accurate measurement and to adapt to changes caused by replacing the curved plate 1 in different measurement situations for accurate measurement of the screwing depth of the fastener 300.

[0041] Further, as shown in Figures 3-5 the adjusting mechanism 400 comprises a transverse adjusting assembly 500 and a longitudinal adjusting assembly 600.

[0042] It should be noted that by setting the transverse adjusting assembly 500 and the longitudinal adjusting assembly 600, the position of the depth gauge 8 on the curved plate 1 is adjusted from the transverse and longitudinal directions respectively. The transverse direction can not only adjust the depth gauge 8 to the center position of the curved plate 1, but also replace different curved plates 1 by means of the sliding cooperation of the curved plate 1 and the sliding plate 3 to adapt to more measurement situations. The longitudinal adjusting assembly 600 can change the measurement range of the depth gauge 8. The distance of the depth gauge 8 in the longitudinal direction can be adjusted according to the general depth range of the fastener 300, so that the measurement depth range of the depth gauge 8 is consistent with the depth range of the fastener 300.

[0043] Further, as shown in Figures 2-4 the transverse adjusting assembly 500 comprises a T-shaped bar 2 provided on one side of the curved plate 1 and a sliding plate 3 slidingly provided on the T-shaped bar 2.

[0044] It should be noted that the T-shaped bar 2 and the sliding plate 3 are connected by sliding to quickly install and replace the curved plate 1 for different size measurement situations.

[0045] Further, as shown in Figures 3-4 the inside of the sliding plate 3 is provided with a T-shaped groove 4, and the T-shaped groove 4 is slidingly matched with the T-shaped bar 2.

[0046] It should be noted that since the curvature of the curved surface of the curved plate 1 is the same as the curvature of the surface of the magnetic steel 200, after the curved plate 1 is assembled by sliding cooperation of the T-shaped bar 2 and the T-shaped groove 4 of the sliding plate 3, the curved plate 1 can be stably attached to the surface of the magnetic steel 200. This attachment mode ensures the stability of the entire detection device during measurement, avoiding measurement errors caused by unstable contact.

[0047] Further, as shown in Figures 3-5As shown, the longitudinal adjustment assembly 600 comprises a slide rod 6 arranged on one side of the sliding plate 3 and a sliding seat 7 sleeved outside the slide rod 6, and the depth gauge 8 is arranged on the top of the sliding seat 7.

[0048] It should be noted that by arranging the sliding seat 7 and the depth gauge 8 on the slide rod 6, the longitudinal position of the depth gauge 8 on the curved plate 1 is changed in a sliding manner, so that the measurement range of the depth gauge 8 can be adjusted, and the size change caused by replacing the curved plate 1 can also be adapted.

[0049] Further, as shown in the figure, Figures 3-5 The sliding plate 3 is provided with a threaded hole, and a locking screw 5 is inserted into the threaded hole.

[0050] It should be noted that when the curved plate 1 is adjusted to the appropriate position by sliding cooperation of the T-shaped strip 2 and the T-shaped groove 4 of the sliding plate 3, the locking screw 5 inserted into the threaded hole can be tightened, and the end of the locking screw 5 will tightly abut against the curved plate 1 during the tightening process, so that the relative position between the curved plate 1 and the sliding plate 3 is fixed by applying friction, preventing displacement of the curved plate 1 due to external force during detection.

[0051] Further, as shown in the figure, Figures 3-5 The bottom of the sliding plate 3 is provided with a rotating seat 9, the rotating seat 9 is rotatably provided with a screw rod 10, one side of the sliding seat 7 is provided with a screw rod 11, and the screw rod 10 is threadedly connected with the screw rod 11.

[0052] It should be noted that the screw rod 10 rotatably arranged on the rotating seat 9 at the bottom of the sliding plate 3 cooperates with the threaded hole in the screw rod 11 at the bottom of the sliding seat 7. In actual measurement, if the curved plate 1 with different radii is replaced, the initial position of the depth gauge 8 is no longer appropriate. At this time, the screw rod 10 can be rotated to drive the screw rod 11 to move forward and backward, and then the sliding seat 7 and the depth gauge 8 installed on the top of the sliding seat 7 are adjusted in the longitudinal direction. Thus, the depth gauge 8 can be quickly adjusted to the appropriate measurement position according to the size and radius of the different curved plate 1, greatly improving the adaptability of the detection device.

[0053] Example three

[0054] As shown in the figure, Figure 5 The same or corresponding parts as in example one are denoted by the same reference numerals as in example one, and for the sake of simplicity, only the differences from example one will be described below. The difference between example three and example one is that:

[0055] The curved plate 1 and the sliding plate 3 are both provided with a scale line 12 for alignment.

[0056] Need to explain, the curved surface board 1 and the sliding plate 3 are provided with the scale line, the alignment of two can be realized quickly in the assembling process, improve the assembling efficiency, reduce the measurement deviation possibility caused by improper assembling.

[0057] Working process

[0058] In use, first, according to the radian of the magnetic steel 200, select the matching radian curved surface board 1, the curved surface board 1 is slid with the T-shaped groove 4 of the T-shaped strip 2 and the sliding plate 3, the scale line on the curved surface board 1 and the sliding plate 3 is quickly aligned, after adjusting to the appropriate position, tighten the locking screw in the threaded hole of the sliding plate 3, fix the curved surface board 1, place the assembled detection device on the magnetic steel 200, make the curved surface board 1 closely adhere to the surface of the magnetic steel 200, if the depth gauge 8 position is not suitable after replacing the curved surface board 1, rotate the lead screw 10 on the rotating seat 9 at the bottom of the sliding plate 3, the lead screw 10 is matched with the threaded hole of the lead screw 11 at the bottom of the sliding seat 7, drive the sliding seat 7 and the depth gauge 8 to move forward and backward, adjust the position of the depth gauge 8, let the measuring end of the depth gauge 8 contact the fastener 300, read the data of the depth gauge 8, obtain the screwing depth of the fastener 300.

[0059] The above only for the preferred embodiment of the utility model has been described, and does not limit the utility model, any modification, equivalent replacement and improvement etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
