Each set of sliding frames has a clamping end mounted on its adjacent side. Each clamping end includes: a slide rail connected to the sliding frame; and a flexible sheet mounted on the side of the slide rail used to clamp the starter end cover. The flexible sheet includes two sets of inclined blocks connected to the slide rail and an elastic metal clamping plate mounted between the two sets of inclined blocks, with the two sets of inclined blocks forming a V-shape.

Description

Technical Field

[0001] This utility model relates to the field of starter technology, and in particular to a starter end cover floating clamping mechanism. Background Technology

[0002] A starter motor is a device that converts electrical energy from a battery into mechanical energy to drive the engine flywheel and start the car engine. The announcement CN210678477U, titled "A Starter Motor End Cover Clamp," mentions that excessive clamping force can easily cause marks and damage to the surface of the starter motor end cover, thus affecting product quality. It addresses this by using a sponge-material anti-pinch sleeve to reduce damage caused during clamping of the starter motor end cover.

[0003] However, when using a sponge-made anti-pinch sleeve to clamp the starter end cover, it is easy to cause unstable clamping, slippage, or even detachment. Sponge is a porous, highly elastic soft material. When pliers or a bench vise apply pressure, the sponge is drastically compressed instead of stably transmitting force to the starter end cover. This results in a significant reduction in effective clamping force and an inability to generate sufficient friction to secure the starter end cover.

[0004] Based on the above, a method is proposed that can stably clamp the starter end cover and reduce the risk of clamping marks and damage to the starter to a certain extent. Utility Model Content

The flexible sheet includes two sets of inclined blocks that are connected to the slide rail and an elastic metal clamping plate installed between the two sets of inclined blocks. The two sets of inclined blocks form a V shape. When the elastic metal clamp is pressed against the starter end cover, the elastic metal clamp fits against the outer wall of the starter end cover.

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes a starter end cover floating clamping mechanism. Please refer to [link / reference]. Figures 1-5 Specifically, when using a sponge-material anti-pinch sleeve to clamp the starter end cover, it is easy to cause unstable clamping, slippage, or even detachment. Based on this, an improvement is proposed: a floating clamping mechanism for the starter end cover, including a fixed platform 1 and two sets of sliding frames 2 slidably mounted on the fixed platform 1. Each set of sliding frames 2 has a clamping end 3 mounted on its adjacent side. The clamping end 3 includes: Slide 31 is connected to slide frame 2; The flexible sheet 32 ​​is installed on one side of the slide rail 31 for clamping the starter end cover. The flexible sheet 32 ​​includes two sets of inclined blocks 321 that are connected to the slide rail 31 and an elastic metal clamping plate 327 installed between the two sets of inclined blocks 321. The two sets of inclined blocks 321 form a V shape. When the elastic metal clamp 327 is pressed against the starter end cover, the elastic metal clamp 327 fits against the outer wall of the starter end cover.

[0024] Specifically, the two sets of sliding frames 2 can slide on the fixed platform 1 to clamp the starter end cover. The starter end cover is clamped by the flexible sheet 32 ​​on the two sets of sliding frames 2. It should be noted that the flexible sheet 32 ​​includes an elastic metal clamp 327. When the elastic metal clamp 327 is pressed against the starter end cover, the elastic metal clamp 327 can fit and press against the starter end cover to a certain extent, limiting the starter end cover and achieving the clamping effect, thus avoiding unstable clamping, slippage or even falling off.

[0025] like Figures 1-2 The fixed platform 1 is shown in detail. The fixed platform 1 has a downward through mounting opening 11 in the middle for placing the starter end cover. The lower end face of the fixed platform 1 is fixed with a mounting shaft 12, which has a telescopic function. The lower end of the mounting shaft 12 is fixed with a support plate 13 for supporting the starter end cover.

[0026] Specifically, when the starter end cover is clamped, it passes through the mounting opening 11 from top to bottom and abuts against the support plate 13 at the lower end. Since most of the end face of the starter end cover is set horizontally, the starter end cover can be kept as vertical as possible when it abuts against the support plate 13, and it is not easy to shift during clamping. It should be noted that the mounting shaft 12 can be telescopically set, so that the height position of the support plate 13 can be adjusted. By manually controlling the position of the support plate 13, the end face of the starter end cover abuts against the support plate 13, so that the starter end cover can be adjusted to be clamped by the elastic metal clamp 327 at different positions, so that the elastic metal clamp 327 ensures that it is pressed against the cylindrical part of the starter end cover.

[0027] like Figures 2-3 The details of each part of the sliding frame 2 are shown. The sliding frame 2 includes a frame 21 that fits against the upper end of the fixed platform 1. The lower end of the frame 21 is provided with a first sliding groove 22 and a second sliding groove 23 that extend along the movement direction of the frame 21. At least two sets of symmetrically arranged L-shaped slide bars 25 and T-shaped slide bars 26 are fixed on the upper end of the fixed platform 1. The two sets of symmetrically arranged L-shaped slide bars 25 are embedded in the first slide groove 22, and the T-shaped slide bars 26 are embedded in the second slide groove 23. The first slide groove 22 of one set of sliding frame 2 has an upwardly extending fixing bolt 24. The driving end of the fixing bolt 24 is located in the two sets of symmetrically arranged L-shaped slide bars 25. The frame 21 of the other set of sliding frame 2 is rotatably connected to a threaded push shaft 28 at one outward end. A stop plate 27 is integrally formed on one side edge of the fixed platform 1. The threaded push shaft 28 passes through the stop plate 27 and is threadedly connected to the stop plate 27. The slide 31 is fixed to the frame 21, and both ends of the slide 31 extend out toward the front and rear sides of the frame 21, respectively.

[0028] Specifically, the slide groove 23 of the frame 21 cooperates with the T-shaped slide bar 26 to limit the frame 21, so that the frame 21 can only move along the extension direction of the T-shaped slide bar 26. The lower end of one set of frame 21 is connected by two sets of symmetrically arranged L-shaped slide bars 25. The two sets of symmetrically arranged L-shaped slide bars 25 have fixing bolts 24 inside. The fixing bolts 24 pass through the frame 21 of the set upwards. The fixing bolts 24 can be fixed by nuts, so that the L-shaped slide bars 25 are pressed against the frame 21 of the set, thus fixing the frame 21 of the set. The other set of frame 21 is driven to slide by a threaded push shaft 28. Rotating the threaded push shaft 28 causes the threaded push shaft 28 to move along the abutment plate 27 connected to it, so that the other set of frame 21 slides.

[0029] like Figures 4-5As shown, a T-shaped opening 311 is provided on the side of the slide 31 away from the slide frame 2, extending along the axis of the slide 31 and passing through both ends of the slide 31. Both sets of inclined blocks 321 are in contact with the slide 31. Each set of inclined blocks 321 has a slider 322 embedded in the slide 31 and whose position in the slide 31 can be adjusted. An elastic metal clamp 327 is installed on the two sets of inclined blocks 321 away from the slide 31.

[0030] Specifically, the two sets of inclined blocks 321 can run along the slide 31, changing the range of opening between the two sets of inclined blocks 321, and can clamp starter end covers of different diameters. It should be noted that even without the elastic metal clamp 327, the two sets of inclined blocks 321 can still clamp the starter end cover.

[0031] The slider 322 has an integral connecting end 323 extending from the opening of the T-shaped opening 311 at one of its outward-facing ends. The outer end of the connecting end 323 is integrally set with the inclined block 321.

[0032] Specifically, since the slider 322 has a T-shaped opening 311 with a T-shaped cross section, there is a gap between the slider 322 and the inclined block 321. The slider 322 is located inside the T-shaped opening 311, and the inclined block 321 is located outside the T-shaped opening 311. The slider 322 and the inclined block 321 need to be connected through the connecting end 323 so that the two form a whole.

[0033] like Figure 5 As shown, a partition plate 324 is attached to the outer side of the slide 31. A bolt threaded through the partition plate 324 and connected to the slider 322 is threaded through it. The partition plate 324 is pressed against the slide 31 by rotating the bolt.

[0034] Specifically, by rotating the bolts on the partition 324, the distance between the partition 324 and the slider 322 can be controlled, the clamping force between the partition 324 and the slider 322 and the slide rail 31 can be controlled, the position of the slider 322 can be fixed, and the slider 322 can be positioned at different positions on the slide rail 31 by rotating the bolts.

[0035] The inclined inner side of the slant block 321 is a flat and smooth surface. When there is no elastic metal clamp 327, the slant block 321 can directly clamp the starter end cover.

[0036] like Figure 5 As shown, the upper end face of the inclined block 321 away from the slide 31 is provided with a downwardly extending but non-penetrating mounting cavity 325, and the inner wall of the mounting cavity 325 is provided with an extension opening 326 that penetrates the inclined block 321. Both ends of the elastic metal clamp 327 have an integral round shaft 328, which is embedded into the respective mounting cavity 325. The extension port 326 clamps the elastic metal clamp 327 near the end.

[0037] Specifically, the mounting cavity 325 and the extension port 326 can cooperate with the round shafts 328 at both ends of the elastic metal clamp 327 to achieve quick installation or removal of the elastic metal clamp 327.

[0038] The elastic metal clamp 327 is pre-bent arc-shaped. It should be noted that when the elastic metal clamp 327 is pressed against the cylindrical part of the starter end cover, it can partially cover the cylindrical part of the starter end cover to a certain extent, increasing the contact area.

[0039] The elastic metal clamp 327 is made of spring steel or high elastic limit alloy steel. It should be noted that when spring steel or high elastic limit alloy steel undergoes bending deformation during clamping, due to its own characteristics, it can relatively return to its original shape after being released, ensuring the stability of the clamping force.

[0040] Working principle: Most of the components of the starter motor are cylindrical, and the starter motor end cover is also cylindrical. The simplest way to clamp the starter motor end cover during processing is to clamp its cylindrical part. Based on this, two sets of sliding frames 2 are set. One set of sliding frames 2 is fixed by a fixing bolt 24, and the other set can slide back and forth by a threaded push shaft 28. By changing the distance between the two sets of sliding frames 2, the flexible sheet 32 ​​on the two sets of sliding frames 2 can clamp the starter motor end cover.

[0041] It should be noted that the flexible sheet 32 ​​includes an elastic metal clamp 327 that clamps the cylindrical part of the starter end cover. Since the elastic metal clamp 327 is a pre-bent arc shape, it can fit and squeeze the cylindrical part of the starter end cover during clamping, increasing the wrapping angle and contact area, so that the clamping force is evenly distributed, achieving the most stable and damage-free clamping.

[0042] Different lengths of elastic metal clamps 327 are required for different diameters, and the two sets of inclined blocks 321 need to be in different positions. Based on this, by rotating the bolts on the partition 324, the slider 322 can be controlled to be in different positions on the slide 31, and the elastic metal clamps 327 of different lengths can be limited. In addition, the elastic metal clamp 327 has round shafts 328 at both ends, which facilitates its cooperation with the mounting cavity 325, making it easy to install or separate the elastic metal clamp 327 from the two sets of inclined blocks 321, and replace the easily damaged elastic metal clamp 327.
