Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0046] Example:

[0047] like Figures 1-10 As shown, the starter stator housing detection fixture 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 to the inner wall of the tube 110. There are four magnetic strips 120, which are evenly distributed circumferentially on the inner wall of the tube 110. The magnetic strip 120 is not only used to cooperate with the slotted snap ring to install the magnet, but it is also magnetized and has a certain function of conducting magnetism, assisting magnetism and changing the magnetic field. Of course, the magnetic strip 120 itself does not have magnetism. The two ends of the tube 110 are respectively provided with a square notch 130 and an arc-shaped notch 140. The tube wall of the tube 110 is provided with a drain outlet 150. The inner wall of the tube 110 is provided with a first protrusion 160 near the square notch 130 and a second protrusion 170 near the arc-shaped notch 140.

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

[0049] The first base 200 can be of any shape, such as a square or circular base. Preferably, the first base 200 is a circular base. The first card holder 220 is disposed on the first base 200. The shape of the first card holder 220 is adapted to the opening of one end of the tube 110. For example, if the tube 110 is a circular tube, then the first card holder 220 is a circular base, and the outer diameter of the first card holder 220 is adapted to the opening diameter of one end of the tube 110, that is, the first card holder 220 can just fit into one end of the tube 110. The first card holder 220 has a positioning notch 221 adapted to the magnetic strip 120 and a first groove 222 adapted to the first protrusion 160, 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 groove 222. The first positioning block 210 is adapted to the aforementioned square notch 130, that is, the first positioning block 210 can just fit into the aforementioned square notch 130, and the first positioning block 210 is provided on the aforementioned first base 200.

[0050] The second seat body 300 can be any shape, such as a square seat body or a round seat body. Preferably, the second seat body 300 is a round seat body. The second seat body 300 is provided with the second seat 320, which is shaped to fit the other end of the tube 110. For example, if the tube 110 is a round tube, the second seat 320 is a round seat body, and the outer diameter of the second seat 320 is adapted to the diameter of the other end of the tube 110, i.e., the second seat 320 can be fitted into the other end of the tube 110. The second seat 320 is provided with the second slot 321, which is adapted to the second protrusion 170, i.e., the second protrusion 170 can be fitted into the second slot 321. The second positioning block 310 is adapted to the arc-like notch 140, i.e., the second positioning block 310 can be fitted into the arc-like notch 140. The second positioning block 310 is provided on the second seat body 300. Furthermore, the second seat body 300 is provided with the support 340, which is provided with a sliding hole. The positioning rod 330 is adapted to the drain 150, and is slidably inserted into the through hole. The positioning rod 330 is used to position the drain 150.

[0051] In the embodiment, the second seat body 300 is connected to the first seat body 200 by a detachable mounting method. Specifically, at least two support rods 600 are fixed to the second seat body 300, and the first seat body 200 is provided with at least two positioning holes. Before detection, the second seat body 300 is separated from the first seat body 200. During detection, the second seat body 300 is mounted on the first seat body 200. The relative positions of the first seat 220, the positioning notch 221, the first slot 222, the first positioning block 210, the second seat 320, the second slot 321, the second positioning block 310, and the positioning rod 330 are determined by the standard shell 100. Specifically, the relative positions of the magnetic aid strip 120, the first protrusion 160, the square-like notch 130, the second protrusion 170, the arc-like notch 140, and the drain 150 are accurate, so that 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 by the standard shell 100. The diameters of the two ends of the tube 110 of the standard shell 100 are accurate, so that the outer diameters of the first seat 220 and the second seat 320 are determined.

[0052] When the tool is used to detect the starter positioning shell 100, first place one end of the tube 110 on the first seat body 200, so that the one end of the tube 110 is sleeved on the first clamping seat 220, the magnetic aid strip 120 and the first protrusion 160 welded on the inner wall of the tube 110 are respectively clamped into the positioning notch 221 and the first slot 222, the square-shaped notch 130 at one end of the tube 110 is clamped on the first positioning block 210, then install the second seat body 300 on the first seat body 200, so that the other end of the tube 110 is clamped on the second clamping seat 320, the arc-shaped notch 140 at the other end of the tube 110 is clamped on the second positioning block 310, the second protrusion 170 on the inner wall of the tube 110 is clamped into the second slot 321, finally, slide the rear positioning rod 330, if the shell 100 meets the requirements, then the positioning rod 330 can be accurately inserted into the drain hole 150, if the shell 100 does not meet the requirements, then the positioning rod 330 cannot be inserted into the drain hole, or the second seat body 300 cannot be installed on the first seat body 200 due to the mispositioning of the arc-shaped notch 140 and the second positioning block 310 or the mispositioning of the second protrusion 170 and the second slot 321, or the tube 110 cannot be sleeved on the first clamping seat 220 due to the mispositioning of the magnetic aid strip 120 and the positioning notch 221 or the mispositioning of the first protrusion 160 and the first slot 222 or the mispositioning of the square-shaped notch 130 and the first positioning block 210.

[0053] Through the above structure, by using the standard shell 100, determining the relative positions of the first clamping seat 220, the positioning notch 221, the first slot 222, the first positioning block 210, the second clamping seat 320, the second slot 321, the second positioning block 310 and the positioning rod 330 on the tool, then the same size shell 100 can be quickly detected in batches to determine whether the relative positions of the magnetic aid strip 120, the first protrusion 160, the second protrusion 170, the arc-shaped notch 140, the square-shaped notch 130 and the drain hole on the shell 100 are correct, with the aid of the tool, the worker only needs to disassemble and assemble the second seat body 300 and the shell 100 on the first seat body 200 to complete the detection, the operation is simple, the detection efficiency is higher, and the detection result is more accurate.

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

[0055] When the first locking structure 400 is unlocked, the first clamping seat 220 can rotate on the first seat body 200, so as to change the relative positions between the positioning notch 221 and the first slot 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, and the relative positions between the positioning notch 221 and the first slot 222 and the first positioning block 210 are 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, so as to change the relative positions 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 locked on the second seat body 300.

[0056] Through the above structure, when the relative positions between 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 by using the standard shell 100, the first locking structure 400 and the second locking structure 500 are unlocked, and then locked after being determined, so that the shells 100 of the same type are detected in batches. When detecting shells 100 of different types, the relative positions between 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 again by using the standard shells 100 of the remaining types. 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 hole 150 of the shells 100 of different types are deviated, through the above method, the tool provided by the embodiment can be used to detect the starter stator shells 100 of different types.

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

[0058] An optional embodiment of the present embodiment is as follows: the first card seat 220 is lapped on the first seat body 200 so that the first card seat 220 can rotate on the first seat body 200, a first screw hole 410 is formed on the first card seat 220, a first arc-shaped through hole 420 is formed on the first seat body 200, and the length of the first arc-shaped through hole 420 is greater than the diameter of the first screw hole 410. The first screw hole 410 and the first arc-shaped through hole 420 are both two, and the two first screw holes 410 and the first arc-shaped through holes 420 correspond one by one. The first locking structure 400 comprises a first bolt 430, which is screwed with the first screw hole 410 after passing through the first arc-shaped through hole 420. In this way, when the first bolt 430 is loosened, the first locking structure 400 is unlocked, and the first card seat 220 can rotate on the first seat body 200, of course, the length of the first arc-shaped through hole 420 determines the rotation angle of the first card seat 220 on the first seat body 200; when the first bolt 430 is tightened, the first locking structure 400 is locked, and the first card seat 220 is locked on the first seat body 200.

[0059] Of course, the first locking structure 400 can also comprise a pressing screw, a cylinder is arranged on the first card seat 220, a circular hole is formed on the first seat body 200, the cylinder is rotatably inserted into the circular hole, a threaded through hole which communicates with the circular hole is formed on the outer wall of the first seat body 200, and the pressing screw is screwed into the threaded through hole; when the pressing screw is tightened, the pressing screw tightly pushes the cylinder in the circular hole, thereby locking the first card seat 220 on the first seat body 200.

[0060] An alternative embodiment of the present embodiment is as follows: the second positioning block 310 is fixed on the outer side wall of a mounting plate 311. The second card seat 320 is stacked with the second seat body 300, and the mounting plate 311 is rotatably stacked between the second card seat 320 and the second seat body 300. The second seat body 300 is provided with a through hole 540, the mounting plate 311 is provided with a second arc-shaped through hole 520, the second card seat 320 is provided with a second threaded hole 510, and the length of the second arc-shaped through hole 520 is greater than the diameter of the through hole 540. The number of the through hole 540, the second arc-shaped through hole 520 and the second threaded hole 510 is two, and the two through holes 540, the second arc-shaped through hole 520 and the second threaded hole 510 correspond one by one. The second locking structure 500 includes a second bolt 530, which is sequentially threaded through the through hole 540 and the second arc-shaped through hole 520 and is screwed with the second threaded hole 510. In this way, when the second bolt 530 is loosened, the second locking structure 500 is unlocked, and the mounting plate 311 can be rotated between the second card seat 320 and the second seat body 300, so that the second positioning block 310 can be rotated on the first seat body 200, and the second card seat 320 is fixed with 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 card seat 320; when the second bolt 530 is tightened, the second locking structure 500 is locked, 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 provided at the center position of the second seat body 300, the mounting plate 311 and the second card seat 320, a screw rod is inserted into the center hole, and a fastening nut 345 is screwed at both ends of the screw rod. When the fastening nuts 345 at both ends are tightened, the second seat body 300, the mounting plate 311 and the second card seat 320 are clamped.

[0062] Alternatively, the bracket 340 is fixed on the outer side 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 assembly plate 341 is provided with a second arc-shaped through hole 520, the length of the second arc-shaped through hole 520 is greater than that of the second bolt 530, and the second bolt 530 is threaded in 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 card seat 320, so that the second positioning block 310 and the bracket 340 for mounting the sliding block are rotatably mounted on the second seat body 300.

[0063] An alternative embodiment of the present embodiment is as follows: the bracket 340 comprises 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 the same as the radial direction of the barrel 110, the movable block 343 is connected to the fixed block 342 through an adjustable connecting structure, so that the position of the sliding hole in the axial direction of the barrel 110 is adjustable. Since the positions of different models of drain outlets in the axial direction of the barrel 110 and / or in the circumferential direction of the barrel 110 are different, when the positions in the circumferential direction of the barrel 110 are different, the second locking structure 500 can be adjusted by loosening and tightening, and when the positions in the axial direction of the barrel 110 are different, the adjustable connecting structure is used for adjustment, so that the tooling provided by the present embodiment can be applied to more models of housings 100.

[0064] Of course, the movable block 343 can also be fixed to the fixed block 342, at this time, the position of the positioning rod 330 in the axial direction of the barrel 110 is not adjustable.
