[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] This utility model provides a positioning device for measuring the dimensions of NdFeB products, such as... Figures 1 to 9 As shown, it includes a base 1, a placement slot 2, a clamping component 3, an elastic reset assembly, and a dial indicator 7.

[0036] In this embodiment, as Figure 1 As shown, the base 1 specifically includes a horizontal base plate 11, two vertical plates 12 set on the horizontal base plate 11, and an operating table 13 erected on the vertical plates 12. The placement slot 2, clamping member 3 and elastic reset assembly are all located on the operating table 13.

[0037] Key points such as Figure 2As shown, the placement slot 2 is used to place the product 8 during measurement. The placement slot 2 has a front opening 21 and a rear opening 22 that extend through the entire structure, and a limiting platform 23 is formed at the front opening 21 for the product 8 to abut against. The cross-section of the placement slot 2 is arc-shaped, higher at both sides and lower in the middle. After the NdFeB product 8 is placed in the placement slot 2, it will naturally gather towards the center under the influence of gravity. The interior of the placement slot 2 can be designed to match the shape of the NdFeB product 8 for easy placement. Figure 7 and Figure 8 As shown, the neodymium iron boron product 8 includes a steel sheet and several neodymium iron boron magnets fixed on the steel sheet. The shape of the steel sheet matches the placement groove 2.

[0038] like Figure 1 and Figure 3 As shown, the clamping member 3 is located at the rear opening 22 of the placement slot 2. In this embodiment, the clamping member 3 is a clamping pin, but it is not limited to this. Any rod-shaped or nail-shaped structure that does not damage the NdFeB product 8 and can contact the NdFeB product 8 can be used as the clamping member 3. The clamping member 3 is connected to the elastic reset component and is driven by the elastic reset component to move back and forth at the rear opening 22 of the placement slot 2. The clamping member 3 presses forward against the rear end of the product 8 in the placement slot 2 and cooperates with the limiting platform 23 to clamp and fix the product 8, preventing the product 8 from shifting during the size measurement process, which would reduce the measurement accuracy.

[0039] In this embodiment, as Figure 1 and Figure 3 As shown, the elastic reset assembly includes a slider 4, an elastic element 5, and a feed rod 6. These components are arranged on the operating table 13 as follows: the operating table 13 is provided with a slide rail 14 extending back and forth, the slider 4 is disposed on the slide rail 14, and slides back and forth along the slide rail 14.

[0040] The slider 4 is L-shaped, and includes a front-to-back extending side and a left-to-right extending side. The front-to-back extending side is connected to the slide rail 14, while the left-to-right extending side extends to the rear end of the placement groove 2, and a mounting hole 41 is provided at this end (see reference). Figure 1 The rear end of the clamping member 3 is fixed in the mounting hole 41, and the front end of the clamping member 3 extends toward the rear opening 22 of the placement groove 2.

[0041] The elastic element 5 is disposed between the slider 4 and the operating table 13 to enable the slider 4 to automatically reset. The elastic element 5 is preferably a return spring, and the return spring can be disposed in, but is not limited to, the following ways:

[0042] Method 1: The reset spring is located between the rear end of slider 4 and the operating table 13, such as... Figure 1As shown, the front end of the return spring is fixedly connected to the slider 4, and the rear end is fixedly connected to the inner wall of the operating table 13. In the initial state, the return spring does not deform; if the slider 4 is slid backward, the slider 4 drives the clamping member 3 to move backward, moving away from the rear opening 22 of the operating table 13. At this time, the return spring is in a compressed state; then, if the slider 4 is released, under the action of the restoring force of the return spring, the slider 4 moves forward to reset.

[0043] Method 2: The return spring is located between the front end of the slider 4 and the operating table 13 (not shown in the figure). The front end of the return spring is fixedly connected to the inner wall of the operating table 13, and the rear end is fixedly connected to the slider 4. Initially, the return spring is not deformed. If the slider 4 is slid backward, the slider 4 drives the clamping member 3 to move backward, moving away from the rear opening 22 of the operating table 13. At this time, the return spring is in a stretched state. Then, if the slider 4 is released, the return force of the return spring moves the slider 4 forward to reset.

[0044] For ease of operation, this design also includes a feed rod 6. (For example...) Figure 1 and Figure 9 As shown, the side wall of the operating table 13 has a movable hole 15 for the feed rod 6 to pass through. The feed rod 6 is a feed screw, which passes through the movable hole 15. Its screw head is located outside the operating table 13 and abuts against the outer side wall of the operating table 13. The other end of the screw head is fixedly connected to the slider 4. A return spring is located between the rear end of the slider 4 and the operating table 13. The front end of the return spring abuts against the slider 4, and the rear end abuts against the inner side wall of the operating table 13.

[0045] In this solution, the tool used to measure the dimensions of product 8 is a dial indicator 7, preferably a digital dial indicator 7 which is more convenient and provides more accurate measurements. Figures 1 to 6 As shown, the dial indicator 7 is located at the front end of the placement slot 2, and the measuring rod of the dial indicator 7 faces the front opening 21 of the placement slot 2 and extends into the product 8 inside the placement slot 2.

[0046] The origin setting and product 8 fixing operation of the positioning device for measuring the dimensions of neodymium iron boron product 8 of this utility model are as follows:

[0047] like Figure 3 As shown, first pull back the feed rod 6, place the original sample block 9 into the placement slot 2, and slowly release the feed rod 6, as shown. Figure 4 As shown, the clamping member 3 pushes against the rear end of the origin sample block 9 and moves forward, making the origin sample block 9 close to the limiting stage 23. At this time, the dial indicator 7 is adjusted to the origin, thus completing the origin setting.

[0048] Then, repeat the same operation, pulling open the feed lever 6, as follows. Figure 5As shown, place the neodymium iron boron product 8, loosen the feed rod 6, and allow the clamping member 3 to engage with the limiting platform 23 to clamp the product 8, as shown. Figure 6 As shown, this design prevents product 8 from easily shifting, thus providing accuracy for subsequent measurements. Once product 8 is fixed in place, measurement operations can be performed using the dial indicator 7.
