Description

Technical Field

[0001] The utility model relates to the technical field of magnetic component product detection, in particular to a product step difference detection tool. Background Art

[0002] The magnetic component product is assembled from a magnetic component and a steel plate. The magnetic component is fixed on the steel plate and located in the center of the steel plate. The distance between the end of the magnetic component and the end of the steel plate is the step difference. The step difference should meet the installation accuracy requirements, and the general accuracy needs to reach 0.05mm. The step difference of existing magnetic component products is usually measured by manually holding a measuring tool. On the one hand, since the magnetic component product itself is magnetic and the measuring tool is mostly made of magnetic conductive material, adsorption is easily generated between the two, and it is difficult for the measuring tool to be adsorbed to a fixed position of the magnetic component. On the other hand, when measuring with a manually holding a measuring tool, due to differences in measurement techniques, the measured step difference error is large and cannot meet the measurement accuracy requirements of the product size. Utility Model Content

[0007] The abutment member is located at the side where the insertion opening of the detection slot is located, and can be horizontally approached or moved away from the detection slot along a first direction, so that when the abutment member is inserted into the detection slot from the insertion opening and approaches the magnetic component product, the magnetic component product can be pushed against so that the end of the steel plate away from the abutment member is pressed against the positioning surface;

[0008] The measuring device is located on the side where the positioning surface of the detection groove is located. A measuring rod is arranged on the measuring device.

[0012] Furthermore, a through hole is formed on the side wall of the slide groove, the inner end of the driving rod passes through the through hole of the slide groove and is fixedly connected to the slider in the slide groove. The outer end of the screw rod is the driving end, and the outer diameter of the driving end is larger than the diameter of the through hole, so that the driving end is limited on the outer surface of the through hole.

[0013] Furthermore, the elastic member is a spring, which is sleeved on the outer periphery of the driving rod, and a mounting groove is formed on the inner wall of the slide groove. One end of the spring is embedded in the mounting groove, and the other end is against the outer surface of the slider.

[0014] Furthermore, it also includes a base, a support assembly and a mounting plate, the support assembly and the mounting plate are fixed on the base, the top side of the support assembly is used to fix the workbench, and the micrometer is fixed on the mounting plate.

[0015] Furthermore, the inner contour of the detection groove is adapted to the outer contour of the bottom side of the steel plate, so that the magnetic component product moves only along the first direction.

[0029] As Figures 1 to 7 shown, the present utility model provides a product step detection tooling for measuring the relative position between the magnetic component 101 and the steel plate 102 on the magnetic component product 100 to confirm whether the fixed position of the magnetic component 101 on the steel plate 102 is within the installation tolerance range. Focusing on Figure 4 shown, the magnetic component 101 is fixed on the top side of the steel plate 102. The magnetic component 101 and the steel plate 102 can adsorb each other and are located in the middle of the steel plate 102. At least both ends of the steel plate 102 in the horizontal first direction protrude from the magnetic component 101.

[0030] Focusing on Figure 1 shown, the specific detection tooling includes a detection groove 1, a measuring device 2 and an abutting member 3; the detection groove 1 is used for placing the magnetic component product 100. The inner contour of the installation groove 53 is adapted to the outer contour of the bottom side of the steel plate 102, so that the magnetic component product 100 can only move along the first direction under the pushing of the abutting member 3. Specifically, a positioning surface 11 is formed at one end of the detection groove 1 along the horizontal first direction, Figure 1 and Figure 2 shown, the arrow direction indicates the first direction. An insertion port 12 is formed at one end departing from the positioning surface 11. The measuring device 2 and the abutting member 3 are respectively located on both sides of the detection groove 1; the abutting member 3 is located on the side where the insertion port 12 of the detection groove 1 is located and can slide horizontally back and forth along the first direction, so that when the abutting member 3 is inserted into the detection groove 1 from the insertion port 12 and approaches the magnetic component product 100, it can push against the magnetic component product 100. Since the steel plate 102 is relatively thin, the abutting member 3 specifically pushes against the magnetic component 101, so that one end of the steel plate 102 departing from the abutting member 3 abuts against the positioning surface 11;

[0031] The measuring device 2 is located on the side where the positioning surface 11 of the detection groove 1 is located. A measuring rod 4 is provided on the measuring device 2. The measuring rod 4 can reciprocate horizontally along the first direction. The measuring device 2 can display the displacement of the measuring rod 4. In this specific embodiment, the measuring device 2 is a micrometer 21. The measuring rod 4 rotates around an axis, one end of which is rotatably fitted on the micrometer 21, and the other end extends towards the abutting member 3. The micrometer 21 has a display screen that can display the displacement of the measuring rod 4. Specifically, the micrometer 21 is an existing micrometer, and its specific structure will not be elaborated here. Of course, it can also be read through a scale. The measuring rod 4 is located above the positioning surface 11 and can at least slide until its end face is longitudinally flush with the positioning surface 11. When it slides into the detection groove 1, its end face abuts against the magnetic component 101. During use, the end face of the measuring rod 4 first remains longitudinally flush with the positioning surface 11. At this time, the reading of the micrometer 21 is zero. When the abutting member 3 pushes the magnetic component product 100 until one end of the steel sheet 102 abuts tightly against the positioning surface 11, the measuring rod 4 slides horizontally in the first direction close to the magnetic component 101 and abuts against the magnetic component 101. The moving distance of the measuring rod 4 is the step difference D between the magnetic component 101 and the end of the steel plate 102 (as Figure 6 shown).

[0032] Focusing on combining Figure 5 and Figure 7 shown, in order to make the measuring rod 4 and the positioning surface 11 longitudinally flush, an origin sample block 9 is further included. The two ends of the origin sample block 9 are respectively formed with an abutting surface 91 and an aligning surface 92. When the origin sample block 9 is placed in the detection groove 1, the abutting surface 91 faces the abutting member 3, and the aligning surface 92 faces the positioning surface 11 and the measuring rod 4. The abutting member 3 can push from the abutting surface 91 to make the aligning surface 92 abut against and fit on the positioning surface 11. The top side of the origin sample block 9 protrudes upward from the top side of the positioning surface 11, and the measuring rod 4 can slide until its end face fits against the aligning surface 92. During use, first, the origin sample block 9 is pushed by the abutting member 3 until the aligning surface 92 fits against the positioning surface 11, and then the measuring rod 4 slides close to the origin sample block 9 until the outer end of the measuring rod 4 abuts against and fits on the aligning surface 92 of the origin sample block 9, and the reading of the micrometer 21 is reset to zero, that is, the setting of the origin position of the measurement is completed.

[0033] Focusing on combining Figure 2 shown, in this specific embodiment, a workbench 5 is further included. Specifically, a base 200, a support assembly 300, and a mounting plate 400 are further included. The support assembly 300 and the mounting plate 400 are fixed on the base 200. The top side of the support assembly 300 is used to fixedly place the workbench 5, and the micrometer 21 is fixed on the mounting plate 400.

[0034] The detection slot 1 is formed on the top side of the workbench 5, and a slide slot 51 is formed on the workbench 5. The abutment 3 is fixedly connected with a slider 6, and the slider 6 is slidably arranged in the slide slot 51. Specifically, a slide rail 54 is arranged in the slide slot 51, and the slider 6 is slidably arranged on the slide rail 54. The slider 6 extends toward the detection slot 1 to form a fixed portion 61, and the fixed portion 61 is located on the side where the socket 12 of the detection slot 1 is located, and the abutment 3 is installed on the fixed portion 61; the slider 6 slides horizontally along the first direction, and an elastic member 7 is arranged between the slider 6 and the slide slot 51, and the elastic member 7 is used to elastically drive the slider 6 to drive the abutment 3 to slide in the direction of the measuring rod 4. Specifically, the elastic member 7 is arranged on the side of the slider 6 away from the measuring rod 4, and a driving rod 8 is arranged on the slider 6, and the driving rod 8 extends in the direction away from the measuring rod 4. The driving rod 8 is used to drive the slider 6 to drive the abutment 3 to slide in the direction away from the measuring rod 4, and compress the elastic member 7, so that when the driving force of the driving rod 8 is removed, the elastic member 7 can elastically drive the slider 6 to slide in the direction of the measuring rod 4.

[0035] In this specific embodiment, the driving rod 8 is a screw rod, the inner end of the screw rod is provided with an external thread, a threaded hole connected to the external thread is provided on the slider 6, and the inner end of the screw rod is screwed to the threaded hole to fix the screw rod on the slider 6; of course, in other embodiments, the driving rod 8 and the slider 6 can also be fixed in other ways, for example, the inner end of the driving rod 8 forms a connecting part, which is fixed to the slider 6 by screws. In addition, a slot can be provided on the slider 6, and a clamping part is provided at the inner end of the driving rod 8, and the clamping part is embedded in the slot to fix the driving rod 8 on the slider 6; it is not limited to this, and technical personnel in this field can design according to specific circumstances.

[0036] In order to facilitate the operation of the driving rod 8, a through hole 52 is formed on the side wall of the slide groove 51. The inner end of the driving rod 8 passes through the through hole 52 of the slide groove 51 and is fixedly connected to the slider 6 in the slide groove 51. The outer end of the screw rod 81 is the driving end 82. The outer diameter of the driving end 82 is larger than the diameter of the through hole 52, so that the driving end 82 is limited on the outer surface of the through hole 52, which can facilitate the driving end 82 to be driven from outside the slide groove 51.

[0037] The elastic member 7 is a spring, which is sleeved on the outer periphery of the driving rod 8. An installation groove 53 is formed on the inner wall of the slide groove 51. One end of the spring is embedded in the installation groove 53, and the other end is against the outer surface of the slider 6. Of course, in other embodiments, at least two springs can be provided, which are respectively located on the opposite sides of the driving rod 8, and the elastic force can also be used to drive the slider 6 to slide toward the measuring rod 4.
