Description

Technical Field

[0001] This application relates to the field of automotive engine equipment and tools technology, and in particular to a device for removing an ignition coil sheath. Background Technology

[0002] When overhauling an engine, it is generally necessary to remove the ignition coil sleeve. Because the ignition coil is interference-fitted to the engine cylinder head, removal is difficult and requires specialized disassembly tools.

[0003] Currently, ignition coil sheath removal tools typically include a mounting bracket and clamping components and locking bolts mounted on the bracket. When removing the ignition coil sheath, the mounting bracket is installed at the location of the sheath to be removed, and the sheath is placed within the clamping components. The clamping components are then tightened with the locking bolts to secure the ignition coil sheath. Finally, external force is applied to remove the ignition coil sheath from the cylinder head.

[0004] However, engines currently equipped with ignition coil sleeves are typically multi-cylinder engines with multiple ignition coil sleeves. When using existing ignition coil sleeve removal tools, each removal of an ignition coil sleeve requires repeatedly installing and removing the mounting bracket, loosening the locking bolts, and tightening the clamps, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0005] Therefore, it is necessary to provide a device for removing ignition coil sheaths to address the problem of low removal efficiency.

[0006] A device for removing an ignition coil sheath from a cylinder head is disclosed. The device includes a slide rail, a support assembly, a pull assembly, and a clamping assembly. The slide rail extends along a first direction and is located on one side of the support assembly along a second direction. The support assembly is configured to position the cylinder head on the side of the slide rail along the second direction. The pull assembly is slidably connected to the slide rail and extends along the second direction. The clamping assembly is connected to the side of the pull assembly opposite to the slide rail and is configured to move the clamping assembly along the second direction away from the support assembly. The clamping assembly defines a clamping cavity to hold the ignition coil sheath. The first direction and the second direction are perpendicular to each other.

[0007] In this embodiment, the cylinder head is positioned on one side of the slide rail along the second direction by a support assembly, and the clamping cavity of the clamping assembly clamps the outer side of the ignition coil sheath. Driven by the pulling assembly, the clamping assembly, holding the ignition coil sheath, moves along the second direction and away from the support assembly, i.e., away from the cylinder head, allowing the ignition coil sheath to be removed from the cylinder head. Furthermore, since the slide rail extends along the first direction, and the pulling assembly is slidably connected to the slide rail, after one ignition coil sheath has been removed, it slides along the slide rail to continue removing the next ignition coil sheath, without needing to move the ignition coil sheath removal device itself, greatly improving removal efficiency.

[0008] In one embodiment, the clamping assembly includes a positioning member and at least two clamping members. The positioning member is connected to the end of the pull-out assembly away from the slide rail and has a cavity extending through in a second direction. The at least two clamping members are assembled together to form a clamping body, with a clamping cavity formed in the middle of the clamping body. The clamping body is placed within the cavity, and the positioning member is configured to move in the second direction away from the support assembly under the action of the pull-out assembly, and to provide a compressive force to the clamping body to clamp the ignition coil sheath.

[0009] In one embodiment, the clamping body slides into the inner wall of the cavity, and there is a gap between at least two adjacent clamping members. The outer contour cross-sectional dimension of the clamping body gradually increases towards the slide rail, and the inner contour cross-sectional dimension of the cavity is greater than the minimum dimension of the outer contour cross-section of the clamping body and less than the maximum dimension of the outer contour cross-section of the clamping body.

[0010] In one embodiment, the positioning element is constructed as a closed ring structure, and the outer wall of each clamping element is constructed as a curved surface structure, with the outer wall of each clamping element slidingly engaging with the inner wall of the closed ring structure.

[0011] In one embodiment, the inner walls of each clamping member together form a clamping cavity, and the inner walls of each clamping member are provided with flanges, and the flanges of the clamping body are provided with the same height.

[0012] In one embodiment, the pulling assembly includes a slider, a connecting rod, and a pulling member. The slider is slidably mounted on a slide rail, and the connecting rod is slidably inserted through the slider in a second direction, with both ends of the connecting rod extending out of the slider. One end passes through the slide rail and is fixedly connected to a clamping assembly, while the other end has a threaded section. The pulling member abuts against the top end of the slider and is threadedly connected to the threaded section.

[0013] In one embodiment, multiple pulling components and clamping components are provided, with each pulling component spaced apart along a first direction and slidably connected to a slide rail, and each clamping component connected to a pulling component.

[0014] In one embodiment, the support assembly includes a support base with a recessed cavity for accommodating the cylinder head. Along a first direction, the top ends of both sides of the support base are provided with grooves, and a slide rail is placed in the grooves and suspended on one side of the top of the cavity.

[0015] In one embodiment, the support assembly further includes a fixing frame, which includes a first frame and two second frames, both of which extend along a second direction. The first frame is connected between the two second frames, and the two first frames are detachably connected to the bottom wall of the receiving cavity. The first frame, the two second frames, and the bottom wall of the receiving cavity together define a locking and limiting cavity.

[0016] In one embodiment, the support assembly includes two support frames, one of which is snapped into one end of the slide rail, and the other support frame is slidably connected to the slide rail; each support frame is provided with a locking bolt at its bottom. Attached Figure Description

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0029] In modern automotive engines, the ignition system plays a crucial role. The ignition coil sheath, as a protective device for the ignition coil, directly affects the engine's operational stability and lifespan. Routine maintenance requires the inspection and replacement of the ignition coil sheath. Typically, the ignition coil sheath is interference-fitted to the engine cylinder head, requiring external force to remove it.

[0030] Currently, engines equipped with ignition coil sleeves (such as alternative fuel engines) are typically multi-cylinder engines, and therefore have multiple ignition coil cylinder liners. See also... Figure 1 , Figure 1 This is a schematic diagram of the structure of an ignition coil sheath disassembly device provided in one embodiment of this application. Figure 1 The image shows the state when the ignition coil sheath is not removed from the cylinder head. Typically, the ignition coil sheath 5 protrudes from one side of the top of the cylinder head 6 and is arranged along the first direction X.

[0031] Ignition coil sheath removal tools in related technologies typically include a mounting bracket and clamping components and locking bolts mounted on the bracket. When removing the ignition coil sheath 5, the mounting bracket is installed at the location of the ignition coil sheath 5 to be removed, and the ignition coil sheath 5 is placed within the clamping components. The clamping components are then tightened with the locking bolts to secure the ignition coil sheath 5. Finally, external force is applied to remove the ignition coil sheath 5 from the cylinder head 6. Using existing ignition coil sheath removal tools requires repeatedly installing the mounting bracket, loosening the locking bolts, and tightening the clamping components for each ignition coil sheath 5 removed, which is time-consuming, labor-intensive, and inefficient.

[0032] In view of the current problem of low disassembly efficiency of ignition coil sleeve 5, this application provides a disassembly device for ignition coil sleeve, which can quickly remove multiple ignition coil sleeves 5 from the cylinder head 6 on the engine.

[0033] To facilitate a clear description of the positional relationships of the various structural features, the first direction X is used to define the arrangement direction of the ignition coil sheath 5, and the second direction Y is used to define the extension direction of the ignition coil sheath 5 relative to the cylinder head 6. The first direction X and the second direction Y are perpendicular to each other.

[0034] See Figure 1 An embodiment of this application provides a disassembly device for ignition coil sheath 5, which is used to remove the ignition coil sheath 5 from the cylinder head 6. The disassembly device for ignition coil sheath 5 includes a support assembly 1, a slide rail 2 provided on the support assembly 1, a pulling assembly 3, and a clamping assembly 4.

[0035] Specifically, the slide rail 2 extends along the first direction X and is located on one side of the support assembly 1 along the second direction Y. The support assembly 1 is configured to position the cylinder head 6 on the side of the slide rail 2 along the second direction Y, so that the slide rail 2 corresponds to the ignition coil sheaths 5 arranged on the cylinder head 6 along the first direction X. The pull assembly 3 is slidably connected to the slide rail 2 and extends along the second direction Y. The clamping assembly 4 is connected to the side of the pull assembly 3 opposite to the slide rail 2, and the pull assembly 3 is configured to drive the clamping assembly 4 to move along the second direction Y away from the support assembly 1. The clamping assembly 4 defines a clamping cavity 40 to clamp the ignition coil sheaths 5.

[0036] When the ignition coil sheath 5 is removed from the cylinder head 6, the clamping cavity 40 of the clamping assembly 4 clamps the outside of the ignition coil sheath 5. Driven by the pulling assembly 3, the clamping assembly 4 moves the ignition coil sheath 5 along the second direction Y, away from the supporting assembly 1, i.e., away from the cylinder head 6, so that the ignition coil sheath 5 is removed from the cylinder head 6. Since the slide rail 2 extends along the first direction X, and the pulling assembly 3 is slidably connected to the slide rail 2, after one ignition coil sheath 5 has been removed, it slides along the slide rail 2 to continue removing the next ignition coil sheath 5, without having to move the ignition coil sheath removal device itself, greatly improving the removal efficiency.

[0037] Wherein, the first direction X can correspond to the length direction of the ignition coil sheath removal device provided in this application, and the second direction Y corresponds to the height direction of the ignition coil sheath removal device. For example, the slide rail 2 is disposed on one side of the top of the support assembly 1, and along the second direction Y, at least a portion of the structure of the support assembly 1 is located between the slide rail 2 and the cylinder head 6.

[0038] In some embodiments, see Figure 1 and Figure 5 , Figure 5 This is a schematic diagram of the structure of the support assembly 1 provided in an embodiment of this application. The support assembly 1 includes a support base 11, which has a recessed cavity 13 for accommodating the cylinder head 6. Along the first direction X, the top ends of both sides of the support base 11 are provided with grooves. The slide rail 2 is placed in the grooves and suspended on one side of the top of the cavity 13. At this time, the cylinder head 6 is placed in the cavity 13, and the slide rail 2 is located on one side of the support base 11 along the second direction Y, i.e., on one side of the top of the support base 11. This allows the cylinder head 6 to be positioned on one side of the slide rail 2 along the second direction Y, facilitating the removal of the ignition coil sheath 5 by the pull assembly 3 and clamping assembly 4 mounted on the slide rail 2. Furthermore, the grooves on the top ends of both sides of the support base 11 allow the slide rail 2 to be supported on the grooves by its own weight. This allows the slide rail 2 to be stably mounted on the support base 11 without the need for other connecting parts, resulting in a simple structure that is easy to assemble and disassemble. Preferably, the grooves are adapted to the outer shape of the slide rail 2 to ensure the stability of the slide rail 2.

[0039] In some embodiments, see Figure 1 The disassembly device for the ignition coil sheath also includes a support rib. The two ends of the support rib are respectively mounted on the top of the side walls on both sides of the receiving cavity 13. The top of the support rib also has a groove, which matches the outer shape of the slide rail 2, and the slide rail 2 is placed within the groove. That is, the support rib supports the slide rail 2 between the slide rail 2 and the support base 11 to further improve the stability of the slide rail 2 mounted on the support base 11. For example, the support rib is mounted in the middle of the support base 11. For example, both ends of the support rib have locking slots, which respectively engage with the side walls of the receiving cavity 13 for easy assembly and disassembly.

[0040] In some embodiments, see Figure 5 The aforementioned support assembly 1 further includes a fixing frame 12, which includes a first frame 121 and two second frames 122. Both second frames 122 extend along the second direction Y. The first frame 121 is connected between the two second frames 122, and the two first frames 121 are detachably connected to the bottom wall of the receiving cavity 13. The first frame 121, the two second frames 122, and the bottom wall of the receiving cavity 13 together define a locking and limiting cavity. In use, the cylinder head 6 is placed inside the receiving cavity 13, and the fixing frame 12 secures the cylinder head 6 within the locking and limiting cavity, preventing the cylinder head 6 from moving in the second direction Y when the ignition coil sheath 5 is removed, thus avoiding interference with the removal of the ignition coil sheath 5.

[0041] For example, the bottom of the support base 11, i.e., the bottom wall of the receiving cavity 13, can be constructed with a through groove, through which the second frame 122 can pass, and the ends of the two second frames 122 away from the first frame 121 are each constructed with threaded sections. In use, the cylinder head 6 is placed in the receiving cavity 13, and the ends of the two second frames 122 away from the first frame 121 pass through the through groove through the bottom wall of the receiving cavity 13. Two nuts are connected to the threaded sections at the ends of one of the second frames 122 on the side of the bottom wall of the receiving cavity 13 away from the cylinder head 6, and the threads are tightened, so that the cylinder head 6 is fixed in the locking and limiting cavity. For example, multiple through grooves can be provided and evenly distributed along the first direction X, so that the fixing frame 12 can fix the cylinder head 6 at different positions in the first direction X.

[0042] For example, two fixing brackets 12 can be provided, located at both ends of the cylinder head 6 along the first direction X, to ensure that the cylinder head 6 can be stably placed in the receiving cavity 13. For example, the first bracket 121 and the two second brackets 122 can be integrally set and jointly constructed into a U-shaped structure, which is simple in structure and easy to manufacture.

[0043] In other embodiments, see Figure 2 , Figure 2 This is a schematic diagram of the structure of an ignition coil sheath removal device provided in another embodiment of this application. The support assembly 1 includes two support frames 11', one of which is snapped into one end of the slide rail 2, and the other support frame 11' is slidably connected to the slide rail 2. Each support frame 11' has a locking bolt at its bottom. In this embodiment, the support frame 11' is mounted on top of the cylinder head 6 using the locking bolts at its bottom, eliminating the need to remove the cylinder head 6 from the engine. This facilitates the removal of the ignition coil sheath 5 from the finished vehicle or engine. Furthermore, the slidable connection between one support frame 11' and the slide rail 2 allows for adaptive adjustment of the distance between the two support frames 11' according to the size of the cylinder head 6, to accommodate cylinder heads of different sizes.

[0044] For example, the support frame 11' can be constructed as a rectangular structure and extend along the second direction Y, with its top connected to the slide rail 2 and its bottom connected to the cylinder head 6 by locking bolts, so as to position the cylinder head 6 on one side of the slide rail 2 along the second direction Y.

[0045] Furthermore, in some embodiments, see [reference] Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the pulling assembly 3 and the clamping assembly 4 provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of a clamping component 4 provided in an embodiment of the present application. The clamping component 4 includes a positioning member 41 and at least two clamping members 42, which together form a clamping body.

[0046] Specifically, the positioning member 41 is connected to the end of the pull assembly 3 away from the slide rail 2, and the positioning member 41 has a cavity extending through the second direction Y. The clamping cavity 40 is formed in the middle of the clamping body, the clamping body is placed in the cavity, and the positioning member 41 is configured to move away from the support assembly 1 along the second direction Y under the drive of the pull assembly 3, and provide a squeezing force to the clamping body to clamp the ignition coil sheath 5.

[0047] When removing the ignition coil sheath 5 from the cylinder head 6, the positioning member 41 is fitted onto the outside of the ignition coil sheath 5, and the clamping members 42 are placed in the cavity to form a clamping body. The clamping cavity 40 in the middle of the clamping body clamps the outer side wall of the ignition coil sheath 5, and under the action of the pulling assembly 3, the positioning member 41 provides a compressive force to the clamping body, causing the clamping cavity 40 to contract and clamp the ignition coil sheath 5. As the pulling assembly 3 continues to move the positioning member 41 along the second direction Y, the positioning member 41 drives the clamping body to remove the ignition coil sheath 5 from the cylinder head 6. The operation is simple and quick, further improving the disassembly efficiency of the ignition coil sheath 5. Preferably, two clamping members 42 are provided, and the two clamping members 42 are assembled together to form the above-mentioned clamping body. It can be understood that the clamping members 42 can also be set to 3, 4, 5 or other numbers.

[0048] In some embodiments, see Figure 4The clamping body slides against the inner wall of the cavity, and at least two adjacent clamping members 42 are separated by a gap. The outer contour cross-sectional dimension of the clamping body gradually increases towards the slide rail 2, and the inner contour cross-sectional dimension of the cavity is greater than the minimum dimension of the outer contour cross-section of the clamping body, but smaller than the maximum dimension of the outer contour cross-section of the clamping body. At this time, when the pulling assembly 3 drives the positioning member 41 and the clamping body to move away from the support assembly 1 along the second direction Y, i.e., towards the slide rail 2, the inner wall of the cavity of the positioning member 41 slides relative to the outer wall of the clamping body. During this sliding process, the inner wall of the cavity of the positioning member 41 squeezes the clamping body, causing each clamping member 42 of the clamping body to move closer to each other. The clamping cavity 40 in the middle is contracted, thereby clamping the ignition coil sheath 5.

[0049] In some embodiments, see Figure 3 and Figure 4 The positioning element 41 is constructed as a closed ring structure, and the outer wall 421 of each clamping element 42 is constructed as a curved surface structure. The outer wall 421 of each clamping element 42 slides and engages with the inner wall 422 of the closed ring structure. The structure is simple and easy to manufacture. For example, the clamping body composed of the clamping elements 42 can be generally constructed as a frustum-shaped structure, and the cavity of the positioning element 41 is constructed as a circular cavity, so that the cavity of the positioning element 41 can form a tight fit with the outer wall 421 of the clamping body, ensuring the reliability of clamping. For example, the inner wall 422 of each clamping element 42 is constructed as a curved surface structure, so that the formed clamping cavity 40 is adapted to the outer shape of the ignition coil sheath 5, avoiding damage to the ignition coil sheath 5 during clamping and removal, thus affecting its reuse.

[0050] Furthermore, the top of the ignition coil sheath 5 typically has a stepped structure, as described in some embodiments, see [reference]. Figure 4 The inner walls 422 of each clamping member 42 together form a clamping cavity 40, and each clamping member 42 has a flange 423 on its inner wall 422. The flanges 423 of the clamping body are all at the same height. In the clamping body assembled from the clamping members 42, the flanges 423 of each clamping member 42 abut against the bottom of the stepped structure of the ignition coil sheath 5 to further ensure the reliability of clamping the ignition coil sheath 5.

[0051] In some embodiments, see Figures 1 to 3The pulling assembly 3 includes a slider 31 slidably mounted on the slide rail 2, a connecting rod 32, and a pulling member 33. Specifically, the connecting rod 32 can be slidably inserted through the slider 31 along the second direction Y, with both ends of the connecting rod 32 extending out of the slider 31. One end passes through the slide rail 2 and is fixedly connected to the clamping assembly 4, while the other end has a threaded section. The pulling member 33 abuts against the top end of the slider 31 and is threadedly connected to the threaded section of the connecting rod 32. By screwing the pulling member 33, the pulling member 33 drives the clamping assembly 4 connected to one end of the connecting rod 32 to move through the threaded engagement with the connecting rod 32, thereby realizing the removal of the ignition coil sheath 5. In this embodiment, the relative movement between the pulling member 33 and the connecting rod 32 is slow and uniform, which facilitates control of the removal process of the ignition coil sheath 5. For example, the pulling assembly 3 can be a nut, which is not only simple in construction but also allows for easy adjustment by using tools, making operation labor-saving.

[0052] For example, see Figure 4 One end of the connecting rod 32 is fixedly connected to a U-shaped frame, and the positioning member 41 is constructed as a ring structure. The U-shaped frame is fixedly connected to the outer walls on both sides of the ring structure. Preferably, the U-shaped frame is fixedly connected to the middle of the ring structure.

[0053] In some embodiments, multiple pull-out components 3 and clamping components 4 are provided. Each pull-out component 3 is spaced apart along the first direction X and is slidably connected to the slide rail 2. Each clamping component 4 is connected to a pull-out component 3. Each pull-out component 3 can simultaneously remove multiple ignition coil sheaths 5 on the cylinder head 6, further improving the removal efficiency. Furthermore, since each pull-out component 3 is slidably connected to the slide rail 2, the spacing between each pull-out component 3 can be adjusted according to the spacing between each ignition coil sheath 5, resulting in good applicability.

[0054] Because this application solves the problems existing in the disassembly process of the ignition coil sheath 5 in the prior art, it has broad application prospects in the fields of internal combustion engine repair, automobile repair, and mechanical equipment repair. Meanwhile, with the popularization and upgrading of automobiles and mechanical equipment, the demand for repair and replacement of ignition systems will continue to increase, thus this application also has potential advantages in terms of market demand. In addition, the support component 1, slide rail 2, and clamping component 4 involved in this application can all be adapted to different models of internal combustion engines and ignition coil sheaths 5 by changing the size of the components, thus possessing a certain degree of versatility and adaptability.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
