Abstract
Description
Technical Field
[0001] This utility model relates to the field of ignition coil processing technology, and in particular to an ignition coil shell trimming device. Background Technology
[0002] The ignition coil of an engine is used to provide high voltage to the spark plugs. The housing of the ignition coil is usually made by stamping. After stamping, the burrs on the housing are trimmed as needed. In the existing technology, the housing is usually fixed in place first, and then trimmed using a carbide rotating blade (plastic) or a laser cutting head (metal). When using different models and batches of ignition coil housings, it is often necessary to adjust the trimming angle of the trimming component. During trimming, it is necessary to ensure that the trimming component does not shift, which could cause trimming errors or even damage to the ignition coil housing. However, the existing method of manually adjusting the position of the trimming component and then fixing its position is inconvenient and needs further improvement and optimization. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide an ignition coil housing trimming device to solve one or more of the problems mentioned above.
[0004] To achieve the above objectives, this utility model provides an ignition coil housing trimming device, including a machine base:
[0005] A base for fixing the ignition coil housing is provided in the middle of the machine base. A frame is fixed on one side of the machine base. A lifting part is provided on the frame. A pressure plate is connected to the bottom of the lifting part. The pressure plate descends toward the base to press the ignition coil housing.
[0006] A circular track is provided on the outer periphery of the base on the machine platform. A slider slides on the circular track and has a telescopic part. The movable end of the telescopic part is connected to a cutting edge part. The bottom end of the slider is slidably connected to a limit plate on the outer side of the circular track. Connecting rods are connected to both sides of the limit plate. Pull ropes are connected to the outer ends of the connecting rods. One end of the pull rope is connected to the movable end of the telescopic part. An elastic element is connected between the connecting rod and the slider so that the connecting rod and the limit plate are in an initial outward elastic state away from the outer side of the circular track. When cutting the edge, the movable end of the telescopic part extends towards the base, causing the pull rope to gradually tighten. The pull rope pulls the outer end of the connecting rod until the limit plate abuts against the outer end face of the circular track.
[0007] Preferably, the base is located at the center of the annular track, and the extension and retraction direction of the telescopic part is toward the radial direction of the annular track.
[0008] Preferably, the top of the annular track is provided with a groove along its circumferential direction, and the bottom of the slider is rotatably connected to a roller, which rolls along the groove.
[0009] Preferably, an anti-slip pad is affixed to the outer end face of the annular track, and multiple spikes are spaced apart on the inner end face of the limiting plate.
[0010] Preferably, the limiting plate is an arc-shaped plate structure that matches the outer end face of the circular track, and the middle position of the limiting plate is slidably connected to the bottom end of the slider.
[0011] Preferably, the connecting rod includes a horizontal bar portion vertically connected to the outside of the limiting plate, and a vertical bar portion connected to the outer end of the horizontal bar portion. The elastic element is a spring connected between the vertical bar portion and the slider, and the pull rope is connected to the top of the vertical bar portion.
[0012] The beneficial effects of this utility model are as follows: A base for fixing the ignition coil housing is provided in the middle of the machine base.

An annular track is provided on the machine base around the outer periphery of the base. A slider is slidably connected on the annular track. The slider is provided with a telescopic part. The movable end of the telescopic part is connected to a cut edge. The bottom end of the slider is slidably connected to a limit plate on the outer side of the annular track. Connecting rods are connected to both sides of the limit plate. Pull ropes are connected to the outer ends of the connecting rods. One end of the pull rope is connected to the movable end of the telescopic part. The connecting rod and the slider are connected by an elastic element, so that the connecting rod and the limiting plate are in an initial outward elastic state away from the outer side of the circular track. In use, the slider can be manually pushed to slide freely along the top of the circular track, so as to conveniently adjust the cutting angle. After the angle is adjusted, when cutting, the movable end of the telescopic part extends towards the base, driving the pull rope to gradually tighten.

[0023] An ignition coil housing trimming device includes a machine base 1. A base 2 for fixing the ignition coil housing is located at the center of the machine base 1. A frame 3 is fixedly mounted on one side of the machine base 1. A lifting part 4 is provided on the frame 3. A pressure plate 5 is connected to the bottom end of the lifting part 4. The pressure plate 5 descends towards the base 2 to press the ignition coil housing. An annular track 6 is provided on the outer periphery of the base 2 on the machine base 1. A slider 7 slides on the annular track 6. The slider 7 has a telescopic part 8. A trimming part 9 is connected to the movable end of the telescopic part 8. The bottom end of the slider 7 is located on the outer side of the annular track 6. The movable connection is a limiting plate 10, and the two sides of the limiting plate 10 are connected to connecting rods 11. The outer end of the connecting rod 11 is connected to a pull rope 12. One end of the pull rope 12 is connected to the movable end of the telescopic part 8. An elastic element 13 is connected between the connecting rod 11 and the slider 7 so that the connecting rod 11 and the limiting plate 10 are in an initial outward elastic state away from the outer side of the annular track 6. When cutting the edge, the movable end of the telescopic part 8 extends towards the base 2, causing the pull rope 12 to gradually tighten. The pull rope 12 pulls the outer end of the connecting rod 11 until the limiting plate 10 abuts against the outer end face of the annular track 6.
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this utility model is based on the existing conventional ignition coil housing trimming device, including a machine base 1. A base 2 for fixing the ignition coil housing is provided at the middle position of the machine base 1. A frame 3 is fixed on one side of the base 2 and the frame 3 is provided with a lifting part 4. A pressure plate 5 is connected to the bottom end of the lifting part 4. Specifically, the base 2 can be designed with a top opening structure, and the shape of the opening end is designed to match the bottom end of the ignition coil housing. The lifting part 4 can adopt existing conventional lifting cylinders and other components. The lifting part 4 is located above the base 2 and is set vertically. In use, the bottom end of the ignition coil housing is inserted into the base 2 in a specific orientation. By controlling the lifting part 4, the pressure plate 5 is driven to descend toward the base 2 to press the top end of the ignition coil housing, thereby fixing the ignition coil housing in a specific orientation.
[0025] Meanwhile, a circular track 6 is provided on the outer periphery of the base 2 on the machine platform 1. A slider 7 is slidably connected on the circular track 6. The slider 7 is provided with a telescopic part 8. The movable end of the telescopic part 8 is connected to a slit part 9. The bottom end of the slider 7 is slidably connected to a limit plate 10 on the outer side of the circular track 6. Connecting rods 11 are connected to both sides of the limit plate 10. A pull rope 12 is connected to the outer end of the connecting rod 11. One end of the pull rope 12 is connected to the movable end of the telescopic part 8. An elastic element 13 is connected between the connecting rod 11 and the slider 7. Figure 3As shown, to make the connecting rod 11 and the limiting plate 10 in an initial outward spring state away from the outer side of the annular track 6, specifically, the telescopic part 8 can adopt existing conventional telescopic cylinders and other components, and the cutting part 9 can adopt existing conventional carbide rotating blades (plastic) or laser cutting heads (metal) and other cutting components. The cutting part 9 can also be equipped with a drive motor and other power components for driving the rotating blade to rotate. In use, such as Figure 5 As shown, the slider 7 can be manually pushed to slide freely along the top of the annular track 6, thereby conveniently adjusting the cutting angle. After the angle is adjusted, during cutting, the movable end of the telescopic part 8 extends towards the base 2, causing the pull rope 12 to gradually tighten. The pull rope 12 pulls the outer end of the connecting rod 11, as shown. Figure 4 As shown, until the limiting plate 10 abuts against the outer end face of the annular track 6, the friction between the limiting plate 10 and the outer end face of the annular track 6 prevents the cutting component on the slider 7 from shifting during the cutting operation. After the cutting is completed, the telescopic part 8 retracts back to its original position, the pull rope 12 is released, and the elastic element 13 drives the connecting rod 11 and the limiting plate 10 to return to the initial outward elastic state away from the outer side of the annular track 6. There is no need for manual fixing and releasing of the limit, making the operation convenient.
[0026] Optionally, the pull rope 12 can adopt existing conventional connecting rope, elastic rope or other structures. The movable end of the telescopic part 8 is connected to the cutting seat 14. The cutting part 9 can be designed as a rotating blade rotatably connected to the cutting seat 14 or a laser head connected to the cutting seat 14. One end of the pull rope 12 can be connected to the connection between the movable end of the telescopic part 8 and the cutting seat 14.
[0027] In the embodiments of this utility model, optionally, such as Figure 1 As shown, the base 2 is located at the center of the circular track 6, and the telescopic part 8 extends in the radial direction of the circular track 6.
[0028] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, the top of the annular track 6 is provided with a groove 61 around its circumference, and the bottom of the slider 7 is rotatably connected to a roller 71. The efficient sliding motion of the slider 7 is achieved by the roller 71 rolling along the groove 61.
[0029] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an anti-slip pad 15 is affixed to the outer end face of the annular track 6. The anti-slip pad 15 can adopt a conventional rubber pad or similar structural design. Multiple spikes 16 are spaced apart on the inner end face of the limiting plate 10, so that during edge cutting, ... Figure 4As shown, the limiting plate 10 abuts against the anti-slip pad 15 on the outer end face of the annular track 6, and the spike 16 pierces into the anti-slip pad 15 to further limit the movement.
[0030] Optionally, the spike 16 can adopt a conventional spike needle structure. By designing the length of the spike 16, when the connecting rod 11 and the limiting plate 10 are in an initial outward spring state away from the outer side of the annular track 6, the spike 16 lightly abuts against the anti-slip pad 15. During adjustment, the slider 7 can be manually pushed to slide freely along the top of the annular track 6, and the spike 16 slides along the outer end face of the anti-slip pad 15 with little resistance. Alternatively, by gently pulling the connecting rod 11 outward, the spike 16 can be further away from the anti-slip pad 15, making it easy to slide the slider 7. After adjusting the position of the slider 7, the spike 16 lightly abuts against the anti-slip pad 15 to prevent the slider 7 from slipping out of the set adjustment position. When cutting the edge, the movable end of the telescopic part 8 extends towards the base 2, driving the pull rope 12 to gradually tighten, so that the limiting plate 10 abuts against the anti-slip pad 15 on the outer end face of the annular track 6, while the spike 16 pierces into the anti-slip pad 15.
[0031] Optionally, angle markings can be marked on the inner or outer circumference of the circular track 6 on the machine tool 1 to facilitate the adjustment of the sliding slider 7 to the set adjustment position.
[0032] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the limiting plate 10 is an arc-shaped plate structure designed to match the outer end face of the circular track 6. The middle position of the limiting plate 10 is slidably connected to the bottom end of the slider 7. Specifically, the middle position of the limiting plate 10 can slide along the bottom end of the slider 7 through the sliding block, and the connecting rod 11 can be pulled inward by the pull ropes 12 on both sides so that the limiting plate 10 slides to the position that abuts against the outer end face of the circular track 6.
[0033] In the embodiments of this utility model, optionally, such as Figure 1 , Figure 2 , Figure 3 As shown, the connecting rod 11 includes a horizontal rod portion 111 vertically connected to the outside of the limiting plate 10, and a vertical rod portion 112 connected to the outer end of the horizontal rod portion 111. The elastic element 13 is a spring connected between the vertical rod portion 112 and the slider 7. The pull rope 12 is connected to the top end of the vertical rod portion 112.
