Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0046] Example:

[0047] like Figure 1-Figure 10 As shown, the starter stator housing inspection tool provided in this embodiment is used to detect whether the relative position of the structure on the starter positioning housing 100 is accurate. The housing 100 includes a tube 110 with openings at both ends and a magnetic strip 120 welded on the inner wall of the tube 110. The number of the magnetic strips 120 is four, and the four magnetic strips 120 are evenly distributed on the inner wall of the tube 110 along its circumference. The magnetic strip 120 is not only used to cooperate with the groove-type retaining spring to install the magnetic steel, but also will be magnetized and have certain magnetic conductivity, magnetic assistance and magnetic field change functions. Of course, the magnetic strip 120 itself does not have magnetism. The two ends of the above-mentioned tube 110 are respectively provided with a square-like notch 130 and an arc-like notch 140, the tube wall of the tube 110 is provided with a drain port 150, and the inner wall of the tube 110 is provided with a first protrusion 160 close to the square-like notch 130 and a second protrusion 170 close to the arc-like notch 140.

[0048] The tooling provided in this embodiment includes a first base 200, a first clamping seat 220, a first positioning block 210, a second base 300, a second clamping seat 320, a second positioning block 310 and a positioning rod 330, wherein:

[0049] The first seat body 200 can be a seat body of any shape, such as a square seat body or a circular seat body. Preferably, the first seat body 200 is a circular seat body. The first clamping seat 220 is arranged on the first seat body 200. The shape of the first clamping seat 220 is adapted to the tube mouth at one end of the tube 110. For example, if the tube 110 is a circular tube, then the first clamping seat 220 is a circular seat body, and the outer diameter of the first clamping seat 220 is adapted to the diameter of the tube mouth at one end of the tube 110, that is, the first clamping seat 220 can just fit into the tube mouth at one end of the tube 110. A positioning notch 221 adapted to the magnetic strip 120 and a first notch 222 adapted to the first protrusion 160 are provided on the first clamping seat 220, that is, the magnetic strip 120 can just fit into the positioning notch 221, and the first protrusion 160 can just fit into the first notch 222. The first positioning block 210 is adapted to the square-like notch 130 , that is, the first positioning block 210 can just fit into the square-like notch 130 . The first positioning block 210 is disposed on the first seat body 200 .

[0050] The second seat body 300 can be a seat body of any shape, such as a square seat body or a circular seat body. Preferably, the second seat body 300 is a circular seat body. The second clamping seat 320 is arranged on the second seat body 300. The shape of the second clamping seat 320 is adapted to the tube mouth at the other end of the tube 110. For example, if the tube 110 is a circular tube, then the second clamping seat 320 is a circular seat body, and the outer diameter of the second clamping seat 320 is adapted to the diameter of the tube mouth at the other end of the tube 110, that is, the second clamping seat 320 can just fit into the tube mouth at the other end of the tube 110. The second clamping seat 320 is provided with a second notch 321 adapted to the second protrusion 170, that is, the second protrusion 170 can just fit into the second notch 321. The second positioning block 310 is adapted to the arc-shaped notch 140, that is, the second positioning block 310 can just fit into the arc-shaped notch 140, and the second positioning block 310 is arranged on the second seat 300. In addition, a bracket 340 is also arranged on the second seat 300, and the bracket 340 is provided with a sliding hole, and the positioning rod 330 is adapted to the drain port 150, and the positioning rod 330 is slidably inserted into the through hole, and the positioning rod 330 is used to position the drain port 150.

[0051] In this embodiment, the second base body 300 is connected to the first base body 200 in a detachable installation manner. Specifically, at least two support rods 600 are fixedly connected to the second base body 300, and at least two positioning holes are opened on the first base body 200, and the support rods 600 are inserted into the positioning holes. Before testing, the second base body 300 is separated from the first base body 200, and during testing, the second base body 300 is installed on the first base body 200. The relative position relationship of the first holder 220, the positioning notch 221, the first slot 222, the first positioning block 210, the second holder 320, the second slot 321, the second positioning block 310 and the positioning rod 330 of the tooling is determined by the standard shell 100. Specifically, the relative position relationship between the magnetic strip 120, the first protrusion 160, the square-like notch 130, the second protrusion 170, the arc-like notch 140 and the drain outlet 150 on the standard shell 100 is accurate, so the relative positions of the positioning notch 221, the first slot 222, the first positioning block 210, the second slot 321, the second positioning block 310 and the positioning rod 330 are determined based on this standard, and the diameters of the two end openings of the tube 110 of the standard shell 100 are accurate, so the outer diameters of the first holder 220 and the second holder 320 are determined based on this.

[0052] When the tool is used to detect the starter positioning housing 100, one end of the tube 110 is first placed on the first seat body 200, so that one end of the tube 110 is sleeved outside the above-mentioned first clamping seat 220, and the magnetic strip 120 and the first protrusion 160 welded on the inner wall of the tube 110 are respectively inserted into the above-mentioned positioning notch 221 and the first notch 222, and the square-shaped notch 130 at one end of the tube 110 is clamped on the above-mentioned first positioning block 210, and then the second seat body 300 is installed on the first seat body 200, so that the other end of the tube 110 is clamped on the above-mentioned second clamping seat 320, and the arc-shaped notch 140 at the other end of the tube 110 is clamped on the second positioning block 310, and the second protrusion 170 on the inner wall of the tube 110 It will be stuck in the above-mentioned second slot 321, and finally, slide the positioning rod 330 to the left rear. If the shell 100 meets the requirements, the positioning rod 330 will be able to be accurately inserted into the above-mentioned drain port 150. If the shell 100 does not meet the requirements, the positioning rod 330 cannot be inserted into the drain hole, or the arc-shaped notch 140 is misaligned with the second positioning block 310 or the second protrusion 170 is misaligned with the second slot 321, resulting in the second seat body 300 cannot be installed on the first seat body 200, or the magnetic strip 120 is misaligned with the positioning notch 221 or the first protrusion 160 is misaligned with the first slot 222 or the square-shaped notch 130 is misaligned with the first positioning block 210, resulting in the tube 110 cannot be sleeved on the first card seat 220.

[0053] Through the above structure, using a standard shell 100, after determining the relative positions of the first socket 220, the positioning notch 221, the first slot 222, the first positioning block 210, the second socket 320, the second slot 321, the second positioning block 310 and the positioning rod 330 on the tool, the shells 100 of the same size can be quickly inspected in batches to determine whether the relative positions of the magnetic strip 120, the first protrusion 160, the second protrusion 170, the arc-shaped notch 140, the square-shaped notch 130 and the drainage hole on the shell 100 are correct. With the help of the tool, the staff only needs to disassemble the second seat body 300 and install the shell 100 on the first seat body 200 to complete the inspection. The operation is simple, the inspection efficiency is higher, and the inspection results are more accurate.

[0054] An optional implementation of this embodiment is as follows: the first positioning block 210 is fixedly disposed on the first base body 200, the first clamping seat 220 is rotatably disposed on the first base body 200, and the first base body 200 is connected with a first locking structure 400 for locking the first clamping seat 220. The second positioning block 310 and the bracket 340 are both rotatably disposed on the second base body 300, and the second base body 300 is connected with a second locking structure 500 for locking the second positioning block 310 and the bracket 340.

[0055] When the first locking structure 400 is unlocked, the first clamping seat 220 can rotate on the first seat body 200, thereby changing the relative position between the positioning notch 221 and the first notch 222 and the first positioning block 210. When the first locking structure 400 is locked, the first clamping seat 220 is locked on the first seat body 200. At this time, the relative position between the positioning notch 221 and the first notch 222 and the first positioning block 210 is determined. When the second locking structure 500 is unlocked, the second positioning block 310 and the bracket 340 can rotate on the second seat body 300, thereby changing the relative position between the second positioning block 310 and the positioning rod 330. When the second locking structure 500 is locked, the second positioning block 310 and the positioning rod 330 are both locked on the second seat body 300.

[0056] Through the above structure, when the relative positions of the positioning notch 221, the first notch 222, the first positioning block 210, the second notch 321, the second positioning block 310 and the positioning rod 330 are determined by using the standard housing 100, the first locking structure 400 and the second locking structure 500 are unlocked, and then locked after the determination is made, so as to perform batch detection on the housings 100 of the same model. When detecting housings 100 of different models, the relative positions of the positioning notch 221, the first notch 222, the first positioning block 210, the second notch 321, the second positioning block 310 and the positioning rod 330 are re-determined by using the standard housings 100 of other models. Because the relative positions of the first protrusion 160, the second protrusion 170, the arc-shaped notch 140, the square-shaped notch 130 and the drain port 150 of the housings 100 of different models are deviated, therefore, through the above method, the tooling provided in this embodiment can be used to detect the starter stator housings 100 of different models.

[0057] Of course, if only one type of starter stator housing 100 needs to be detected, the first clamping seat 220 and the first fixing block 342 can be fixedly installed on the first seat body 200, and the second clamping seat 320, the second fixing block 342 and the bracket 340 can be fixedly installed on the second seat body 300.

[0058] An optional implementation of this embodiment is as follows: the first clamping seat 220 is overlapped on the first base 200 so that the first clamping seat 220 can rotate on the first base 200, a first screw hole 410 is provided on the first clamping seat 220, a first arc-shaped through hole 420 is provided on the first base 200, and the length of the first arc-shaped through hole 420 is greater than the aperture of the first screw hole 410. There are two first screw holes 410 and two first arc-shaped through holes 420, and the two first screw holes 410 correspond to the first arc-shaped through holes 420 one by one. The first locking structure 400 includes a first bolt 430, and the first bolt 430 passes through the first arc-shaped through hole 420 and is screwed with the first screw hole 410. In this way, when the first bolt 430 is loosened, the above-mentioned first locking structure 400 is unlocked, and the first clamping seat 220 can be rotated on the first seat body 200. Of course, the length of the above-mentioned first arc-shaped through hole 420 determines the rotation angle of the first clamping seat 220 on the first seat body 200; when the first bolt 430 is tightened, the above-mentioned first locking structure 400 is locked, and the first clamping seat 220 is locked on the above-mentioned first seat body 200.

[0059] Of course, the first locking structure 400 may also include a compression screw, a cylinder is arranged on the first clamping seat 220, a circular hole is opened on the first seat body 200, the cylinder is rotatably inserted in the circular hole, a threaded through hole connected to the circular hole is opened on the outer wall of the first seat body 200, the compression screw is threaded in the threaded through hole, and when the compression screw is tightened, the compression screw pushes the cylinder into the circular hole, thereby locking the first clamping seat 220 on the first seat body 200.

[0060] An optional implementation of this embodiment is as follows: the second positioning block 310 is fixed on the outer wall of a mounting plate 311. The second clamping seat 320 is stacked with the second seat body 300, and the mounting plate 311 is rotatably stacked between the second clamping seat 320 and the second seat body 300. The second seat body 300 is provided with a through hole 540, and the mounting plate 311 is provided with a second arc-shaped through hole 520. The second clamping seat 320 is provided with a second screw hole 510, and the length of the second arc-shaped through hole 520 is greater than the aperture of the through hole 540. The number of the through hole 540, the second arc-shaped through hole 520 and the second screw hole 510 is two, and the two through holes 540, the second arc-shaped through hole 520 and the second screw hole 510 correspond to each other. The second locking structure 500 includes a second bolt 530, and the second bolt 530 passes through the through hole 540 and the second arc-shaped through hole 520 in sequence and is screwed with the second screw hole 510. Thus, when the second bolt 530 is loosened, the second locking structure 500 is unlocked, and the mounting plate 311 can rotate between the second clamping seat 320 and the second seat body 300, so that the second positioning block 310 can rotate on the first seat body 200, and the second clamping seat 320 is bolted and fixed to the second seat body 300 by the second bolt 530. The length of the second arc-shaped through hole 520 determines the rotation angle of the mounting plate 311 between the second seat body 300 and the second clamping seat 320; when the second bolt 530 is tightened, the second locking structure 500 is above, thereby locking the mounting plate 311 and the second positioning block 310 on the second seat body 300.

[0061] Of course, a center hole can also be opened at the center position of the second base body 300, the mounting plate 311 and the second clamping base 320, a screw can be inserted into the center hole, and fastening nuts 345 can be screwed on both ends of the screw. When the fastening nuts 345 at both ends are tightened, the second base body 300, the mounting plate 311 and the second clamping base 320 are clamped.

[0062] Optionally, the bracket 340 is fixed on the outer wall of an assembly plate 341, and the assembly plate 341 is rotatably stacked between the mounting plate 311 and the second seat body 300. The mounting plate 341 is provided with a second arc-shaped through hole 520, and the length of the second arc-shaped through hole 520 is greater than the second bolt 530, and the second bolt 530 is inserted into the second arc-shaped through hole 520. In this way, when the second bolt 530 is tightened, not only the mounting plate 311 and the second positioning block 310 are fixed on the second seat body 300, but also the assembly plate 341 and the bracket 340 are fixed on the second seat body 300; when the second bolt 530 is loosened, the mounting plate 311 and the assembly plate 341 can be rotated between the second seat body 300 and the second clamping seat 320, so that the second positioning block 310 and the bracket 340 for mounting the slider are both rotatably mounted on the second seat body 300.

[0063] An optional implementation of this embodiment is as follows: the bracket 340 includes a fixed block 342 and a movable block 343, one end of the fixed block 342 is fixedly connected to the outer wall of the assembly plate 341, a sliding hole is opened in the movable block 343, and the axial direction of the sliding hole is in the same direction as the radial direction of the tube 110, and the movable block 343 is connected to the fixed block 342 through an adjustable connection structure, so that the position of the sliding hole in the axial direction of the tube 110 is adjustable. Since the positions of different types of drainage holes in the axial direction of the tube 110 and / or in the circumferential direction of the tube 110 are different, when the positions in the circumferential direction of the tube 110 are different, they can be adjusted by loosening or tightening the second locking structure 500, and when the positions in the axial direction of the tube 110 are different, they are adjusted by the above-mentioned adjustable connection structure, so that the tooling provided in this embodiment can be applicable to the detection of more types of housings 100.

[0064] Of course, the movable block 343 can also be fixed on the fixed block 342. In this case, the position of the positioning rod 330 in the axial direction of the tube 110 cannot be adjusted. It should be noted that the axial direction of the positioning rod 330 is in the same direction as the radial direction of the tube 110.

[0065] Specifically, the adjustable connection structure includes a stud 344 and two locking nuts 345. The stud 344 is fixed on the movable block 343. The fixed block 342 is provided with a through hole. The stud 344 is slidably inserted into the through hole. The two locking nuts 345 are both screwed on the stud 344, and the two locking nuts 345 are respectively located on both sides of the fixed block 342. In this way, when the two locking nuts 345 are tightened on the stud 344, the two locking nuts 345 clamp the fixed block 342, thereby locking the movable block 343 on the fixed block 342; when the locking nuts 345 are loosened, adjustment can be performed.

[0066] Of course, the above-mentioned adjustable connection structure can also be a telescopic rod with an outer tube and an inner shaft, one end of the outer tube is fixed on the above-mentioned fixed block 342, the inner shaft is slidably inserted in the outer tube, one end of the outer tube is fixed on the above-mentioned movable block 343, and a locking bolt is threaded on the tube wall of the outer tube. When the locking bolt is tightened, the locking bolt presses the above-mentioned inner shaft into the outer tube. When the locking bolt is loosened, adjustment can be performed.

[0067] In order to prevent the positioning rod 330 from falling off from the sliding hole, the positioning rod 330 in this embodiment has a head end and a tail end. The head end is used to insert into the drainage hole, and the tail end is fixed with a baffle 331. The outer diameter of the baffle 331 is the aperture of the above-mentioned sliding hole. An anti-slip structure can also be detachably installed in the middle part of the positioning rod 330. The anti-slip structure cooperates with the baffle 331 to prevent the positioning rod 330 from falling off from the sliding hole.

[0068] Optionally, the anti-slip structure is a locking pin 332 , and a pin hole is provided in the middle of the positioning rod 330 , and the locking pin 332 is pin-connected to the pin hole. Of course, the anti-slip structure is screwed to a screw sleeve on the locking pin 332 .

[0069] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
