Description

Technical Field

[0002] like Figure 1 As shown, the starter stator includes an outer shell (i.e., a cylinder 910) and a magnet 930. The outer shell is a tubular structure with openings at both ends. Four magnetic strips 920 are welded inside the outer shell, and the four magnetic strips 920 are evenly distributed along the circumference of the outer shell. A magnet 930 is installed between every two magnetic strips 920, that is, four magnets 930 are installed inside the starter stator, and each magnet 930 is fixed to the corresponding magnetic strip 920 by a slotted retaining spring 940, so that the magnet 930 is fixed inside the starter stator.

[0003] like Figure 2 As shown, the slotted retaining spring 940 is a clamping structure in the shape of a long slot body, which belongs to the prior art. Two clamping feet 950 are arranged at both ends of the slotted retaining spring 940. In the natural state, the clamping feet 950 are flush with the slot wall of the slotted retaining spring 940. When clamping, the clamping feet 950 of the slotted retaining spring 940 are opened to the side. When clamping the magnetic steel 930, as shown in FIG. Figure 1 As shown, the clamping feet 950 at both ends of the slot-shaped clamping spring 940 clamp the two ends of the magnetic auxiliary strip 920 and the magnetic steel 930 respectively.

This process is time-consuming and labor-intensive, and it is difficult to ensure that the degree of opening of the clamping foot 950 is uniform, which ultimately results in a poor clamping effect of the magnet 930 in the housing.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The starter stator assembly tool provided by the present invention includes a base, a lower mold base and an upper mold base. The starter stator includes a cylinder, a magnetic strip, a magnetic steel and a grooved retaining spring. The magnetic strip is fixed to the inner wall of the cylinder by welding, and the magnetic steel is fixed to the magnetic strip by means of a grooved retaining spring, so that the magnetic steel is fixed to each part of the starter stator. The tool provided by the present invention is used to open the clamping foot of the grooved retaining spring, thereby utilizing the clamping foot of the grooved retaining spring to clamp the magnetic steel to the magnetic strip. Specifically, the lower die seat of the tooling is installed on the base, and the lower die seat is provided with a lower plug column for inserting the groove-type retaining spring, and the root of the lower plug column is provided with two lower inclined blocks, and the two lower inclined blocks are respectively located on both sides of the lower plug column, and the upper die seat is provided with an upper plug column for inserting the groove-type retaining spring, and the root of the upper plug column is provided with two upper inclined blocks, and the two upper inclined blocks are respectively located on both sides of the upper plug column, when the upper die seat is pressed down, the two lower inclined blocks respectively open the two clamping feet at one end of the groove-type retaining spring, and the two upper inclined blocks respectively open the two clamping feet at the other end of the groove-type retaining spring.

[0032] When assembling the starter stator, first overlap one end of the cylinder of the starter stator on the base and make the cylinder sleeved outside the lower die seat, and make the magnetic strip welded on the inner wall of the cylinder overlap on the lower die seat, then install the magnetic steel into the cylinder, make the magnetic steel close to the magnetic strip, and then insert the grooved retaining spring into the lower plug-in column from top to bottom, so that the two clamping feet at one end of the grooved retaining spring overlap the two lower inclined surface blocks at the root of the lower plug-in column respectively, finally align the upper die seat with the lower die seat and align the upper plug-in column with the lower plug-in column, and then press the upper die seat downward, so that the upper plug-in column is inserted from top to bottom into the other end of the above-mentioned grooved retaining spring. During the pressing process, the two upper inclined surfaces at the root of the upper plug-in column After the block contacts the two clamping feet at the other end of the slot-type retaining spring, the downwardly pressed upper inclined surface block will exert an opening force on the two clamping feet at the other end of the slot-type retaining spring, causing the two clamping feet at the other end of the slot-type retaining spring to open outward. At the same time, with the help of friction, the slot-type retaining spring will move downward synchronously, while the magnetic steel and the auxiliary magnetic strip are overlapped on the lower die base and cannot move downward. At this time, the slot-type retaining spring moving downward will cause the two clamping feet at one end to be squeezed onto the two lower inclined surface blocks at the root of the lower plug column, and the two lower inclined surface blocks are used to exert an opening force on the two clamping feet at one end of the slot-type retaining spring, causing the two clamping feet at one end of the slot-type retaining spring to also open outward.

[0033] Through the above structure, the tooling can simultaneously open the two clamping feet at both ends of the slot-type retaining spring. When in use, it is only necessary to press the upper die seat downward with the help of a press or manpower. The operation is simple and convenient, and the two upper inclined surface blocks and the two lower inclined surface blocks are of the same size. In this way, it can be ensured that the clamping feet at the same end of the slot-type retaining spring are opened to the same extent. Moreover, when the downward pressure of the upper die seat is controlled within a reasonable range, it can also be ensured that the clamping feet at both ends of the slot-type retaining spring are opened to the same extent. Therefore, the starter stator assembly tooling provided by the present invention is simple and convenient to use, has strong practicality, and can better clamp the magnetic steel in the cylinder. It should be noted that after the clamping feet at the ends of the slot-type retaining spring are opened, the corresponding magnetic steel will be clamped on the corresponding magnetic auxiliary strip.

DETAILED DESCRIPTION

[0046] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. 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.

[0047] Example:

[0048] The present embodiment provides a starter stator assembly tool, which is used to open the clamping foot 950 of the slotted retaining spring 940 that has been placed in place, so that the clamping foot 950 of the slotted retaining spring 940 can expand and clamp the magnet 930 on the auxiliary magnetic strip 920. It is worth noting that currently, the clamping foot 950 of the slotted retaining spring 940 that has been placed in place is usually opened by manually holding pliers to open the clamping foot 950 of the slotted retaining spring 940. The tool provided in the present embodiment replaces the manual work of opening the clamping foot 950 of the slotted retaining spring 940. It should be noted that if Figure 1 As shown in FIG. 1 , the current starter stator includes a cylinder 910, a magnetic strip 920, a magnetic steel 930, and a slotted retaining spring 940. There are four magnetic strips 920, which are welded and fixed on the inner wall of the cylinder 910. The magnetic strips 920 are long strips used to help install the magnetic steel 930. The magnetic steel 930 is also called a magnetic tile, which is a conventional component in the starter stator. The slotted retaining spring 940 is as shown in FIG. Figure 1 and Figure 2As shown, it is a long strip-shaped slot body with two clamping feet 950 at each end. In the natural state, the clamping feet 950 are flush with the slot wall of the slot-shaped retaining spring 940. In the clamped state, the clamping feet 950 are bent to the side and open. The two clamping feet 950 at the same end of the slot-shaped retaining spring 940 are in contact with the magnet 930 and the auxiliary magnetic strip 920 respectively. The clamping feet 950 at both ends of the slot-shaped retaining spring 940 are respectively signed at the two ends of the magnet 930 and the auxiliary magnetic strip 920, thereby clamping the magnet 930 on the auxiliary magnetic strip 920, so that the magnet 930 is fixed in the cylinder 910 (that is, the outer shell) of the starter stator.

[0049] The starter stator assembly tool provided in this embodiment is as follows Figure 3-Figure 9 As shown, it includes a base 100, a lower mold base 200 and an upper mold base 300, wherein:

[0050] The top surface of the base 100 is set to be a plane, and the shell of the starter stator (that is, the above-mentioned cylinder 910) is vertically placed on the top surface of the base 100 so that one end of the cylinder 910 overlaps the top surface of the base 100.

[0051] The lower die seat 200 is installed on the base 100. The shape of the lower die seat 200 is adapted to the inner hole of the cylinder 910. When the cylinder 910 is overlapped on the top surface of the base 100, the cylinder 910 will also be sleeved outside the lower die seat 200, so that the lower die seat 200 plays a certain positioning role on the cylinder 910. The lower die seat 200 is provided with a lower plug column 210, and two lower inclined surface blocks 220 are provided at the root of the lower plug column 210. The two lower inclined surface blocks 220 are respectively located on both sides of the lower plug column 210. The upper die seat 300 is provided with an upper plug column 310, and two upper inclined surface blocks 320 are provided at the root of the upper plug column 310. The two upper inclined surface blocks 320 are respectively located on both sides of the upper plug column 310.

[0052] When the upper die seat 300 is pressed downward, the two lower inclined surface blocks 220 respectively open the two clamping feet 950 at one end of the slot-shaped retaining spring 940 , and the two upper inclined surface blocks 320 respectively open the two clamping feet 950 at the other end of the slot-shaped retaining spring 940 .

[0053] Before use, the upper die base 300 is completely distributed with the lower die base 200 and the base 100. When assembling the starter stator, first overlap one end of the cylinder 910 of the starter stator on the base 100 and make the cylinder 910 sleeved outside the lower die base 200, and make the magnetic strip 920 welded on the inner wall of the cylinder 910 overlap on the top surface of the lower die base 200, and then install the magnetic steel 930 into the cylinder 910 so that the magnetic steel 930 is close to the magnetic strip 920. 0 and overlapped on the top surface of the lower die base 200, and then the grooved retaining ring 940 is inserted from top to bottom into the lower plug column 210, so that the two clamping feet 950 at one end of the grooved retaining ring 940 are respectively overlapped on the two lower inclined surface blocks 220 at the root of the lower plug column 210, and finally the upper die base 300 is aligned with the lower die base 200 and the upper plug column 310 is aligned with the lower plug column 210, and then the upper die base 300 is pressed down, so that the upper plug column 310 is inserted from top to bottom into the above-mentioned grooved retaining ring 940. During the downward pressing process, the other end of the retaining spring 940, after the two upper inclined blocks 320 at the root of the upper plug column 310 come into contact with the two clamping feet 950 at the other end of the groove retaining spring 940, the downward pressed upper inclined block 320 will exert an opening force on the two clamping feet 950 at the other end of the groove retaining spring 940, so that the two clamping feet 950 at the other end of the groove retaining spring 940 are stretched outward. At the same time, with the help of friction, the groove retaining spring 940 will be synchronously moved The grooved retaining spring 940 moves downward, while the magnetic steel 930 and the auxiliary magnetic strip 920 overlap on the lower mold base 200 and cannot move downward. At this time, the grooved retaining spring 940 moving downward will cause the two clamping feet 950 at one end to be squeezed onto the two lower inclined blocks 220 at the root of the lower plug column 210. The two lower inclined blocks 220 are used to apply an opening force on the two clamping feet 950 at one end of the grooved retaining spring 940, so that the two clamping feet 950 at one end of the grooved retaining spring 940 are also stretched outward.

[0054] Through the above structure, the tooling can simultaneously open the two clamping feet 950 at both ends of the slot-type clamping spring 940. When in use, it is only necessary to press the upper die seat 300 downward with the help of a press or manpower. The operation is simple and convenient, and the two upper inclined surface blocks 320 and the two lower inclined surface blocks 220 have the same size and shape. In this way, it can be ensured that the clamping feet 950 at the same end of the slot-type clamping spring 940 are opened to the same extent. Moreover, when the downward pressure of the upper die seat 300 is controlled within a reasonable range, it can also be ensured that the clamping feet 950 at both ends of the slot-type clamping spring 940 are opened to the same extent. Therefore, the starter stator assembly tooling provided by the present invention is simple and convenient to use, has strong practicality, and can better clamp the magnetic steel 930 in the cylinder 910. It should be noted that after the clamping feet 950 at the ends of the slot-type clamping spring 940 are opened, the corresponding magnetic steel 930 will be clamped on the corresponding magnetic auxiliary strip 920.

[0055] like Figure 6 and Figure 7As shown, the upper bevel block 320 in this embodiment is actually a block structure with at least two inclined outer surfaces. The bottom surface of the upper bevel block 320 and the surface close to the outer edge of the upper mold base 300 are inclined outer surfaces. Specifically, the bottom surface of the upper bevel block 320 is inclined downward from the side away from the upper plug column 310 to the side close to the upper plug column 310, and the surface of the upper bevel block 320 close to the outer edge of the upper mold base 300 is inclined from the side close to the outer edge of the upper mold base 300 to the inner side of the upper mold base 300. Slanted; the lower bevel block 220 in the present embodiment is actually a block structure having at least two inclined outer surfaces, the top surface of the lower bevel block 220 and the surface close to the outer edge of the lower mold base 200 are inclined outer surfaces, specifically, the top surface of the lower bevel block 220 is inclined upward from the side away from the lower plug column 210 toward the side close to the lower plug column 210, and the surface of the lower bevel block 220 close to the outer edge of the lower mold base 200 is inclined from the side close to the outer edge of the lower mold base 200 toward the inner side of the lower mold base 200.

[0056] With the two inclined outer surfaces of the upper inclined surface block 320, when the upper inclined surface block 320 applies pressure on the foot 950 at the other end of the grooved retaining spring 940, the inclined outer surface will press the foot 950 at the other end of the grooved retaining spring 940 outwardly, so that the foot 950 is stretched outwardly. With the two inclined outer surfaces of the lower inclined surface block 220, when the grooved retaining spring 940 is overlapped on the lower inclined surface block 220, the foot 950 at one end of the grooved retaining spring 940 is actually overlapped on the top surface of the lower inclined surface block 220. When the grooved retaining spring 940 moves downward, the inclined outer surface of the lower inclined surface block 220 will press the foot 950 at one end of the grooved retaining spring 940 outwardly, so that the foot 950 is stretched outwardly.

[0057] Of course, when the grooved retaining spring 940 is inserted into the lower plug column 210, a certain downward pressure can be applied to the grooved retaining spring 940, so that the clamping foot 950 at one end of the grooved retaining spring 940 directly applies pressure on the lower inclined surface block 220, and the clamping foot 950 at one end of the grooved retaining spring 940 is first stretched open by the reaction force applied to the clamping foot 950 at one end of the grooved retaining spring 940 by the lower inclined surface block 220.

[0058] Optionally, the number of the above-mentioned lower plug-in columns 210 is multiple, and the multiple lower plug-in columns 210 are evenly distributed in the circumferential direction of the lower mold base 200, and a placement position is formed between every two lower plug-in columns 210, and each placement position is placed with a magnetic strip 920 and a magnetic steel 930. The number of upper plug-in columns 310 is also multiple, and the multiple upper plug-in columns 310 are evenly distributed in the circumferential direction of the upper mold base 300, and the positions of the multiple upper plug-in columns 310 and the multiple lower plug-in columns 210 correspond one by one. Specifically, the number of upper plug-in columns 310 and lower plug-in columns 210 is determined according to the number of magnetic steels 930 installed inside the starter stator. This embodiment is described by taking four magnetic steels 930 installed inside the starter stator as an example, that is, the number of upper plug-in columns 310 and lower plug-in columns 210 in this embodiment is four. The corresponding upper plug-in column 310 and lower plug-in column 210 are simultaneously inserted into a slotted retaining spring 940, that is, the tooling can simultaneously act on four slotted retaining springs 940 installed in the cylinder 910, thereby simultaneously opening all the clamping pins 950 of all the slotted retaining springs 940 inside a starter stator.

[0059] Of course, if only three magnets 930 are installed in the starter stator, correspondingly, only three slotted retaining rings 940 are needed. In this case, the number of the upper inserting posts 310 on the upper die base 300 and the number of the lower inserting posts 210 on the lower die base 200 are both three. And so on.

[0060] In order to smoothly insert the upper plug 310 into the grooved retaining ring 940, the upper plug 310 in this embodiment is provided with a second insertion guide head 330 at one end away from the upper die holder 300 (i.e., the bottom end of the upper plug 310), and in order to smoothly insert the lower plug 210 into the grooved retaining ring 940, the lower plug 210 in this embodiment is provided with a first insertion guide head 230 at one end away from the lower die holder 200 (i.e., the top end of the lower plug 210). Both the first insertion guide head 230 and the second insertion guide head 330 are pointed structures.

[0061] An optional implementation of this embodiment is as follows: the base 100 includes a cup body 110 and a cover plate 120. The top of the cup body 110 is penetrated to form a cup mouth. The cover plate 120 overlaps the top of the cup body 110 and blocks the cup mouth. The cover plate 120 is bolted and fixed to the bottom of the cup body 110 by connecting bolts 130. In this way, the interior of the base 100 forms an installation cavity. The cover plate 120 is used to overlap the cylinder 910, and the lower mold base 200 is installed on the cover plate 120.

[0062] The lower die base 200 in this embodiment can be fixedly mounted on the top surface of the cover plate 120 (i.e., the base 100), or can be connected to the top surface of the cover plate 120 in an adjustable manner. Optimally, the lower die base 200 is installed on the cover plate 120 in an adjustable manner. Specifically, a second arc-shaped long through groove is provided on the cover plate 120, a second screw hole is provided on the bottom surface of the lower die base 200, and a second clamping bolt 600 is also included. The second clamping bolt 600 passes through the second arc-shaped long through groove and is screwed to the second screw hole. The length of the second arc-shaped long through groove is greater than the outer diameter of the second clamping bolt 600, so that the installation position of the lower die base 200 on the cover plate 120 is adjustable. When it is necessary to adjust the installation position of the lower die base 200 on the cover plate 120, the second clamping bolt 600 is loosened, but the second clamping bolt 600 is still screwed in the second screw hole. At this time, there is a gap between the nut of the second clamping bolt 600 and the edge of the second arc-shaped long through groove. Therefore, the lower die base 200 can be rotated on the cover plate 120 (that is, the base 100) to adjust the orientation of the lower die base 200. After the adjustment, the second clamping bolt 600 is tightened again so that the nut of the second clamping bolt 600 presses the edge of the second arc-shaped long through groove and locks it by friction. In this way, the installation position of the above-mentioned lower die base 200 on the base 100 can be adjusted according to the starter stator model, thereby adjusting the position of the lower plug 210.

[0063] In order to make the placement of the cylinder 910 on the base 100 more precise, in the present embodiment, a positioning block 400 is also installed on the above-mentioned cover plate 120. It should be noted that a notch 960 is provided at one end of the cylinder 910 of the starter stator. When the cylinder 910 is overlapped on the cover plate 120 of the above-mentioned base 100, the above-mentioned positioning block 400 is inserted into the above-mentioned notch 960 to position the cylinder 910 on the cover plate 120.

[0064] The positioning block 400 in this embodiment can be fixedly mounted on the cover plate 120, or can be connected to the cover plate 120 in an adjustable manner. Optimally, the positioning block 400 is installed on the cover plate 120 in an adjustable manner. Specifically, the positioning block 400 is provided with a first arc-shaped long through slot, the cover plate 120 is provided with a first screw hole, and further includes a first clamping bolt 500, which passes through the first arc-shaped long through slot and is screwed to the first screw hole. The length of the first arc-shaped long through slot is greater than the outer diameter of the first clamping bolt 500, so that the installation position of the positioning block 400 on the cover plate 120 is adjustable. When the position of the positioning block 400 needs to be adjusted, the first clamping bolt 500 is loosened, but the first clamping bolt 500 is still screwed in the first screw hole. At this time, there is a gap between the nut of the first clamping bolt 500 and the edge of the first arc-shaped long through groove. Therefore, the positioning block 400 can be rotated on the cover plate 120 to adjust the installation position of the positioning block 400 on the cover plate 120. After the adjustment, the first clamping bolt 500 is tightened again so that the nut of the first clamping bolt 500 presses the edge of the first arc-shaped long through groove and locks it by friction. In this way, the installation position of the above-mentioned positioning block 400 on the base 100 can be adjusted according to the starter stator model. It should be noted that the position of the notch 960 on the cylinder 910 of different models of starter stators is different.

[0065] An optional implementation of this embodiment is as follows: a convex tube 140 is also provided on the top surface of the cover plate 120, and the lower die base 200 is provided with a center hole adapted to the convex tube 140, and the convex tube 140 is rotatably inserted in the center hole, so that it can play a certain positioning role in the installation of the lower die base 200 on the base 100, and the inner hole of the convex tube 140 and the inner cavity of the cup body 110 are connected to form an installation cavity, and the lower plug column 210 is located on the side of the convex tube 140. An ejection mechanism is installed in the installation cavity, and the ejection mechanism is used to push up the upper die base 300 after being pressed down, so that the lower die base 200 after being pressed down can automatically bounce upwards, which is convenient for removing the upper die base 300.

[0066] When in use, the upper mold base 300 is placed on the above-mentioned ejection mechanism, and the upper plug column 310 on the upper mold base 300 is aligned with the lower plug column 210 on the lower mold base 200, and then pressure is applied to the upper mold base 300 using a press or by hand to press the upper mold base 300 downward. After the downward pressing is completed, the upper mold base 300 is released, and the ejection mechanism automatically ejects the upper mold base 300 upward.

[0067] Optionally, the ejection mechanism includes an ejector rod 700 and a spring 800, wherein:

[0068] The push rod 700 is inserted into the convex tube 140 in a sliding manner up and down, and the top end of the push rod 700 is located above the convex tube 140. The spring 800 is installed in the installation cavity, and the two ends of the spring 800 are respectively in contact with the bottom end of the push rod 700 and the bottom of the cup body 110. When in use, the upper mold base 300 is overlapped on the top end of the push rod 700, and the push rod 700 moves downward to compress the spring 800. When the upper mold base 300 is opened, the spring 800 rebounds and moves the push rod 700 upward, thereby lifting the pressed upper mold base 300 upward. The upper plug column 310 is located on the side of the push rod 700.

[0069] In order to prevent the push rod 700 from being pushed out of the convex tube 140 by the spring 800, in this embodiment, a slider 710 adapted to the inner hole of the convex tube 140 is provided at the bottom end of the push rod 700, and the outer diameter of the slider 710 is larger than the push rod 700, that is, the outer diameter of the push rod 700 is smaller than the inner hole diameter of the convex tube 140, and the slider 710 is slidably placed in the convex tube 140 up and down, and an annular baffle 141 is fixed at the top end of the convex tube 140. The inner ring hole is adapted to the above-mentioned push rod 700, and the push rod 700 is slidably inserted in the inner ring hole of the above-mentioned annular baffle 141, and the top end of the push rod 700 is located above the annular baffle 141, and the inner ring hole diameter of the annular baffle 141 is smaller than the outer diameter of the above-mentioned slider 710. In this way, when the spring 800 pushes the push rod 700 upward to the extreme point, the annular baffle 141 blocks the above-mentioned slider 710 so that the slider 710 and the push rod 700 will not detach from the convex tube 140.

[0070] Of course, the ejection mechanism can also be an electric mechanism, for example, the ejection mechanism includes an ejector rod 700 and an electric telescopic rod, the ejector rod 700 is slidably inserted into the convex tube 140, the electric telescopic rod is installed in the installation cavity and is electrically connected to the power supply and the controller (such as a chip), the telescopic end of the electric telescopic rod is connected to the ejector rod 700, and the telescopic direction of the telescopic end of the electric telescopic rod is the up and down direction. When the upper mold base 300 is pressed down, the electric telescopic rod is controlled to retract synchronously, and when the upper mold base 300 is pressed down to the right position, the upper mold base 300 is released, and the electric telescopic rod is controlled to extend to lift the ejector rod 700.

[0071] 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 who is familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
