Description

Technical Field

[0001] This application relates to the field of vehicle technology, and specifically to a stripping assembly and stripping device. Background Technology

[0002] With the continuous development and application of automotive-related technologies, the need to remove the engine oil pan while the vehicle is in its entirety is frequently encountered during automotive repair and production trials. In existing designs, the oil pan and engine block are firmly bonded together due to the application of sealant. The traditional method involves removing all the oil pan fixing bolts and then using a wedge tool to tap into the engine and cylinder block mating surface to loosen the sealant. However, in a fully functional vehicle, the engine compartment is compact and relatively narrow, resulting in insufficient space for tapping along the mating surface, significantly increasing the difficulty of the operation. Furthermore, when using a wedge tool, the limited operating space and the tool's inherent characteristics make it very easy to damage the engine and cylinder block mating surface. Once damaged, this can lead to a series of problems such as poor sealing and oil leaks, affecting the normal operation of the engine and the overall performance of the vehicle.

[0003] There is an urgent need for a stripping tool that is easy to operate and can be used in confined spaces for stripping oil pans. Utility Model Content

[0004] To address the technical problem of difficulty in separating the oil pan from the engine, this application provides a stripping assembly and a stripping device.

[0005] In a first aspect, this application provides a peeling assembly, including a supporting outer shell and a sliding inner core. The sliding inner core extends through the height direction of the supporting outer shell and is connected to a driving member. The driving member drives the sliding inner core to reciprocate along the height direction of the supporting outer shell. The supporting outer shell and the sliding inner core maintain an elastic connection. In a first state, the top surfaces of the supporting outer shell and the sliding inner core are flush, forming a flush area. The flush area is configured to jointly form an insertion plane, and the supporting outer shell and the driving member maintain surface-to-surface contact. In a second state, the top surface of the sliding inner core protrudes beyond the top surface of the supporting outer shell, and the supporting outer shell and the driving member maintain surface-to-surface contact.

[0006] According to the above technical means, since the sliding inner core can pass through the supporting outer shell and be connected to a driving component, while maintaining an elastic connection between the sliding inner core and the supporting outer shell, in the first state, the insertion plane formed by the top surface of the supporting outer shell and the sliding inner core can be adaptively inserted into the preset hole position of the mating surface between the oil pan and the engine. In the second state, the driving component drives the sliding inner core to move away from the driving component, so that the top surface of the sliding inner core protrudes beyond the top surface of the supporting outer shell. That is, the top surface of the sliding inner core can be used to push the upper engine block plane or oil pan plane, and the top surface of the supporting outer shell can be used to push the lower oil pan plane or engine block plane to fit together (matting surface position). In this way, the sliding inner core and the supporting outer shell can simultaneously apply opposite forces to the oil pan and cylinder block plane at the disassembly hole (preset hole position). When the force is greater than the adhesive force of the oil pan adhesive, the oil pan can be peeled off.

[0007] Optionally, in the first state, a first preload is formed at the connection between the driving member and the sliding inner core, and a first elastic resistance is formed at the elastic connection position between the sliding inner core and the supporting outer shell. Under the combined action of the first preload and the first elastic resistance, the top surface of the supporting outer shell and the sliding inner core remain flush, and the supporting outer shell and the driving member remain in contact. In the second state, a second preload is formed at the connection between the driving member and the sliding inner core, and a second elastic resistance is formed at the elastic connection position between the sliding inner core and the supporting outer shell. At the same time, the top surface of the sliding inner core bears an external force. Under the combined action of the first preload, the first elastic resistance, and the external force, the top surface of the sliding inner core protrudes beyond the top surface of the supporting outer shell, and the supporting outer shell and the driving member remain in contact.

[0008] Based on the above technical means, the sliding inner core, the supporting outer shell, and the driving component maintain structural stability in the axial direction.

[0009] Optionally, the sliding inner core includes a first abutting portion and a transmission portion connected to the first abutting portion; one end of the supporting outer shell has a guide groove, and a pair of second abutting portions are formed on both sides of the guide groove; the transmission portion is used to pass through the supporting outer shell along the guide groove and is connected to the driving member in a transmission manner; the first abutting portion is sandwiched between the two second abutting portions.

[0010] According to the above technical means, during the reciprocating movement of the drive unit along the height direction of the support shell, the support shell and the drive unit always remain in contact. The first abutment part and the second abutment part keep their top surfaces flush, or the first abutment part protrudes from the second abutment part. The transmission part of the sliding inner core passes through the support shell along the guide groove and is connected to the drive unit through the transmission part. By combining the fact that the first abutment part and the second abutment part are kept flush or that there is a height misalignment relationship between them after relative movement, the non-axial driving force of the drive unit can be converted into axial travel power during this process, thereby adapting to the application of peeling tools in narrow spaces.

[0011] Optionally, an elastic element is connected between the first abutting part and the supporting shell, the elastic element is sleeved outside the transmission part, the top surfaces of the first abutting part and the second abutting part are flush, or the first abutting part protrudes out of the second abutting part.

[0012] Based on the above technical means, the elastic element can be used to provide force buffering, enabling the sliding inner core to move stably in the axial direction.

[0013] Optionally, the driving component includes a connecting portion, the connecting portion includes a supporting surface, and the supporting housing and the supporting surface always remain in contact.

[0014] According to the above technical means, the driving component includes a connecting part with a supporting surface, which can match the fitting relationship between the supporting shell and the supporting surface. Furthermore, by combining the axial preload formed between the driving component and the transmission part in the transmission connection, and the elastic connection relationship between the sliding inner core and the supporting shell, it can further ensure that the supporting shell will not detach from the supporting surface and move in the axial or circumferential direction, thereby further maintaining the overall structural stability.

[0015] Optionally, a cavity bottom surface is formed between the guide groove and the supporting housing, and the elastic element is connected between the first abutment portion and the cavity bottom surface.

[0016] According to the above technical means, the sliding inner core generates elastic abutment pressure on the bottom surface of the cavity (i.e., the supporting shell) through the elastic element, and the driving element has a supporting force on the supporting shell. Under the combined action of the elastic abutment pressure and the supporting force, the supporting shell can stably fit against the supporting surface of the connecting part in the driving element.

[0017] Optionally, the first abutting portion includes a first insertion plane and a first abutting platform, with a first recessed area between the first insertion plane and the first abutting platform, and the elastic member is connected between the first abutting platform and the bottom surface of the cavity; the first abutting platform is connected to one end of the transmission portion.

[0018] According to the above technical means, the first abutment platform can be used to restrict the elastic element from coming out of the sliding inner core, and the first abutment platform, the elastic element and the bottom surface of the cavity together form an elastic limiting structure, which can further ensure the stability of the overall structure; the first recessed area can facilitate the formation of an L-shaped structure by the first insertion plane.

[0019] Optionally, the second abutment portion includes a second insertion plane and an extension sub-portion. A second recessed region is provided between the second insertion plane and the extension sub-portion. The second recessed region is adapted to the first recessed region so that when the top surfaces of the first insertion plane and the second insertion plane are flush, the first recessed region and the second recessed region together form a clearance space.

[0020] According to the above-mentioned technical means, the second insertion plane can form an insertion plane suitable for the preset disassembly hole together with the first insertion plane. At the same time, the clearance space formed by the first recessed area and the second recessed area can be suitable for users in narrow spaces for portable applications.

[0021] Optionally, the transmission part includes a smooth rod part and a threaded part connected to the smooth rod part, the elastic element is sleeved on the smooth rod part, the driving element is threadedly connected to the threaded part, and the smooth rod part is connected to the first abutment platform.

[0022] According to the above technical means, the drive component rotates and, through the threaded connection with the threaded part, converts the rotational motion into the axial linear motion of the transmission part; the elastic element is sleeved on the smooth rod part, which can buffer the impact force during the movement and avoid rigid collision damage to the components; the smooth rod part is connected to the first abutment platform, which can realize the axial positioning of the transmission part, prevent its axial movement, improve structural stability, ensure that the entire system can operate smoothly, and ensure transmission accuracy.

[0023] Secondly, this application provides a stripping device, including the stripping assembly described above.

[0024] The beneficial effects of this application are:

[0025] The peeling assembly and peeling device provided in this application embodiment employ a sliding inner core that passes through a supporting outer shell and is connected to a driving member. The driving member can drive the sliding inner core to reciprocate along the height direction of the supporting outer shell, and the supporting outer shell and the sliding inner core maintain an elastic connection. Thus, during the reciprocating movement of the sliding inner core relative to the supporting outer shell in its own height direction, the elastic resistance between the sliding inner core and the supporting outer shell ensures that the supporting outer shell remains in a surface-to-surface contact with the driving member, preventing the supporting outer shell from moving in the height direction; that is, the supporting outer shell and the driving member remain relatively stationary. In the first state, the top surface of the supporting outer shell and the sliding inner core form an insertion... In the first state, the sliding inner core is a flat surface that can be adapted to the preset hole position between the oil pan and the engine. In the second state, the driving component drives the sliding inner core to move away from the driving component, so that the top surface of the sliding inner core protrudes from the top surface of the supporting shell. In this way, the top surface of the sliding inner core can be used to push the upper engine block plane or oil pan plane, and the top surface of the supporting shell can be used to push the lower oil pan plane or engine block plane to fit together (joint surface position). In this way, the sliding inner core and the supporting shell can simultaneously apply opposite forces to the oil pan and cylinder block plane at the disassembly hole (preset hole position). When the force is greater than the adhesive force of the oil pan adhesive, the oil pan can be peeled off. Attached Figure Description

[0035] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0036] The first embodiment of this application provides a stripping assembly, which is a stripping tool used in automotive repair and production prototyping processes to separate the oil pan from the engine cylinder. Figures 1-5 As shown, the peeling component 1 is applied to the disassembly hole 1A on the mating surface between the oil pan and the cylinder. It can achieve the peeling of the oil pan from the cylinder block by applying force to both the oil pan and the cylinder simultaneously, with minimal damage to the mating surface. Furthermore, the peeling component 1 has a simple structure, is highly operable, and is applicable to most vehicle models, making it widely applicable. Therefore, the illustration only provides a simplified indication of the location of the disassembly hole 1A and does not specify the shape or size of the disassembly hole 1A.

[0037] The stripping assembly 1 includes a supporting housing 11, a sliding inner core 12, and a driving member 13. At least a portion of the sliding inner core 12 is fitted inside the supporting housing 11, and at least a portion of the sliding inner core 12 protrudes from the supporting housing 11. The supporting housing 11 is a shell structure, and the sliding inner core 12 is a sliding rod-like structure or a sliding column-like structure. The sliding inner core 12 extends along the height direction of the supporting housing 11 and is driveably connected to the driving member 13. The driving member 13 drives the sliding inner core 12 to reciprocate along the height direction of the supporting housing 11. For example, the height direction here refers to the height direction of the supporting housing 11 (or the height extension direction of the supporting housing 11) in the use state of the stripping assembly 1, which can also be understood as the height direction between the oil pan and the engine in the use state. For example, the drive connection is to convert non-axial forces into forces along the height direction of the supporting housing 11, thereby enabling the sliding inner core 12 to reciprocate along the height direction. The stripping assembly 1 can be adapted for use in confined spaces, that is, it can strip the oil pan from the engine cylinder in confined space scenarios.

[0038] Considering the overall structural stability of the peeling component 1, the supporting shell 11 and the sliding inner core 12 are kept in an elastic connection. An elastic abutment force will be generated at the elastic connection position. Under the setting of this elastic abutment force, the supporting shell 11 can always maintain a surface-to-surface contact with the driving component 13.

[0039] The peeling component 1, applied in this application embodiment, can have two states, including a first state and a second state. In the first state, the supporting outer shell 11 and the top surface A of the sliding inner core 12 are kept flush, forming a flush region B. The flush region B is configured to jointly form an insertion plane C, which is then inserted into the core. Figure 1At the location indicated by the disassembly hole 1A, the support housing 11 and the driving member 13 maintain a surface-to-surface contact state. That is, the driving member 13 provides a supporting force F6 for the support housing 11 and the sliding inner core 12, and at the same time, provides a driving force for the sliding inner core 12. For example, the driving member 13 can convert a driving stroke in a non-axial or non-height direction into a driving stroke in the axial or height direction. In the second state, the top surface A of the sliding inner core 12 protrudes from the top surface A of the support housing 11, and the support housing 11 and the driving member 13 maintain a surface-to-surface contact state. Specifically, the driving member 13 can drive the sliding inner core 12. The moving inner core 12 moves away from the driving member 13 so that the top surface A of the sliding inner core 12 protrudes from the top surface A of the supporting outer shell 11. That is, the top surface A of the sliding inner core 12 can be used to push the upper engine block plane or oil pan plane, and the top surface A of the supporting outer shell 11 can be used to push the lower oil pan plane or engine block plane to fit together (joint surface position). In this way, the sliding inner core 12 and the supporting outer shell 11 can simultaneously apply opposite forces to the oil pan and the cylinder plane of the disassembly hole 1A (preset hole position). When the force is greater than the adhesive force of the oil pan adhesive, the oil pan can be peeled off.

[0040] Considering the specific force distribution among the sliding inner core 12, the supporting outer shell 11, and the driving member 13, in the peeling assembly 1 provided in this application embodiment, in the first state, a first preload F1 is formed at the connection between the driving member 13 and the sliding inner core 12 (i.e., the connection with the transmission part 122 mentioned later). This first preload F1 is generated along the axial direction of the sliding inner core 12 (i.e., the transmission part 122). A first elastic resistance F2 is formed between the elastic member 14 and the sliding inner core 12 (i.e., the first abutment part 121) and the supporting outer shell 11 (i.e., the cavity bottom surface 1111 mentioned later). The elastic member 14 is relatively to the sliding inner core 12 (i.e., the first abutment part 121). 21) The direction of the first elastic resistance force F2 is axially toward the top surface A of the sliding inner core 12 (i.e., the first abutment part 121), and the direction of the first elastic resistance force F2 of the elastic member 14 relative to the supporting shell 11 (i.e., the bottom surface 1111) is axially toward the direction of the driving member 13; thus, under the combined action of the first preload force F1 and the first elastic resistance force F2, the top surface A of the sliding inner core 12 (i.e., the first abutment part 121) and the supporting shell 11 (i.e., the second abutment part 112) remain flush, and the supporting shell 11 and the driving member 13 (i.e., the support surface 1311 of the connecting part 131 described later) always remain in contact.

[0041] In the second state, a second preload force F3 is formed at the connection between the driving member 13 and the sliding inner core 12 (i.e., the transmission part 122). This second preload force F3 is generated along the axial direction of the sliding inner core 12 (i.e., the transmission part 122). A second elastic resistance force F4 is formed between the elastic member 14 and the sliding inner core 12 (first abutment part 121) and the supporting shell 11 (i.e., the cavity bottom surface 1111). The direction of the second elastic resistance force F4 of the elastic member 14 relative to the sliding inner core 12 (i.e., the first abutment part 121) is along the axial direction of the sliding inner core 12 (i.e., the transmission part 122). The top surface A of the sliding inner core 12 (i.e., the first abutment portion 121) faces axially, and the direction of the second elastic resistance force F4 of the elastic member 14 relative to the supporting outer shell 11 (i.e., the cavity bottom surface 1111) is axially towards the direction of the driving member 13. Simultaneously, the top surface A of the sliding inner core 12 (i.e., the first abutment portion 121) bears an external force F5, which acts axially towards the direction of the driving member 13 relative to the sliding inner core 12 (i.e., the first abutment portion 121). Under the combined action of the first preload F1, the first elastic resistance force F2, and the external force F5, the top surface A of the sliding inner core 12 (i.e., the first abutment portion 121) protrudes from the top surface A of the supporting outer shell 11 (i.e., the second abutment portion 112), and the supporting outer shell 11 remains in contact with the driving member 13 (i.e., the support surface 1311 of the connecting portion 131). Thus, a static force balance is maintained among the sliding inner core 12, the supporting outer shell 11, and the driving member 13.

[0042] Considering that the supporting shell 11 guides the sliding inner core 12, and the specific structural schemes of the supporting shell 11 and the sliding inner core 12, in the peeling assembly 1 provided in this application embodiment, the sliding inner core 12 includes a first abutting part 121 and a transmission part 122 connected to the first abutting part 121; wherein, one end of the first abutting part 121 is used to adapt to the insertion of the disassembly hole 1A, and the other end of the first abutting part 121 is used to maintain an axial elastic connection with the supporting shell 11. In addition, one end of the supporting shell 11 has a guide groove 111. The first abutment part 121 and the transmission part 122 of the sliding inner core 12 can be inserted into the supporting shell 11 along the guide groove 111. The two sides of the guide groove 111 form a pair of spaced second abutment parts 112. The first abutment part 121 is sandwiched between the two second abutment parts 112. The transmission part 122 passes through one end of the supporting shell 11 and is used for transmission connection with the driving member 13. That is, through the transmission connection between the driving member 13 and the transmission part 122, the sliding inner core 12 can be provided with a driving force to reciprocate along the guide groove 111.

[0043] For example, the transmission unit 122 adopts a transmission shaft structure.

[0044] Furthermore, an elastic member 14 is connected between the first abutment portion 121 and the supporting shell 11. The elastic member 14 is sleeved outside the transmission portion 122. Thus, under the working action of the elastic member 14 and the driving member 13, based on the axial preload between the driving member 13 and the transmission portion 122 and the elastic abutment force between the first abutment portion 121 and the supporting shell 11, the supporting shell 11 can always keep in contact with the driving member 13. By further adjusting the moving distance of the sliding inner core 12 using the driving member 13, the first abutment portion 121 and the second abutment portion 112 can be kept flush with the top surface A, or the first abutment portion 121 can be made to protrude from the second abutment portion 112.

[0045] During the reciprocating movement of the drive unit 13 and the transmission unit 122 along the height direction of the support housing 11, the support housing 11 and the drive unit 13 remain in contact. The top surfaces A of the first abutment part 121 and the second abutment part 112 are kept flush. This can be understood as the top surfaces A of the first abutment part 121 and the second abutment part 112 being flush, forming a flush area B. The flush areas B of the first abutment part 121 and the second abutment part 112 together form an insertion plane C, which can be adapted to insert... In the disassembly hole 1A of the oil pan and the oil cylinder mating surface; or, the first abutting part 121 protrudes from the second abutting part 112. It can be understood that as the driving member 13 drives the transmission part 122, the sliding inner core 12 can be moved toward the side away from the driving member 13. That is, the first abutting part 121 of the sliding inner core 12 can be driven to move in the axial direction, and the first abutting part 121 can be changed from a state of being flush with the second abutting part 112 to a state of protruding from the top surface A of the second abutting part 112.

[0046] Considering the specific solution of keeping the support shell 11 and the transmission part 122 in constant contact, in the peeling assembly 1 provided in this application embodiment, the driving member 13 includes a connecting part 131. Here, the connecting part 131 can be understood as a structure that is directly used to support the support shell 11 and will not generate driving force on the support shell 11.

[0047] Specifically, the connecting part 131 includes a supporting surface 1311, and the supporting shell 11 and the supporting surface 1311 are always in contact. Here, the supporting surface 1311 is a surface area that is adapted to and in contact with the bottom surface of the supporting shell 11. Considering the actual application scenario of the peeling component 1, the bottom surface of the supporting shell 11 can be any of the following: a plane, a curved surface, or a polyhedron. The supporting surface 1311 of the connecting part 131 on the driving member 13 can be any of the following: a plane, a curved surface, or a polyhedron that is adapted to the bottom surface of the supporting shell 11. It can refer to the connection scenario structure of fitting, abutting, snapping, or embedding.

[0048] Considering the specific scheme of maintaining an elastic connection between the sliding inner core 12 and the supporting outer shell 11, in the peeling assembly 1 provided in the embodiments of this application, a cavity bottom surface 1111 is formed between the guide groove 111 and the supporting outer shell 11. The cavity bottom surface 1111 and the supporting outer shell 11 are detachably connected, or the cavity bottom surface 1111 and the supporting outer shell 11 are integrally formed; the elastic member 14 is connected between the first abutment part 121 and the cavity bottom surface 1111.

[0049] For example, the elastic element 14 can be any of the following: spring, rubber product, elastic metal sheet, etc. Any of the above elastic elements 14 only needs to have restorable elastic contraction performance in the axial direction.

[0050] For example, the spring may include a helical spring or a disc spring, wherein the helical spring may include either a tension spring or a compression spring.

[0051] Considering the specific structural scheme of the first abutment portion 121, in the peeling assembly 1 provided in this application embodiment, the first abutment portion 121 includes a first insertion plane 1211 and a first abutment platform 1212. The first insertion plane 1211 is used to form a portion of the insertion plane C that adapts to the disassembly hole 1A. The first abutment platform 1212 is used to connect the elastic member 14 and can restrict the elastic member 14 from disengaging along the circumferential direction of the sliding inner core 12. Furthermore, a first recessed region 1213 is provided between the first insertion plane 1211 and the first abutment platform 1212, which facilitates the formation of an L-shaped structure for the first insertion plane 1211. In this way, the elastic member 14 can be connected between the first abutment platform 1212 and the bottom surface 1111 of the cavity. The first abutment platform 1212 can prevent the elastic member 14 from coming out of the sliding inner core 12 in the axial direction. Since the elastic member 14 is sleeved on the outer periphery of the transmission part 122 and the first abutment platform 1212 is connected to one end of the transmission part 122, the transmission part 122 can restrict the elastic member 14 from coming out in its own circumferential direction.

[0052] For example, the first abutment 1212 protrudes in the circumferential direction from the outer contour surface of the transmission part 122 in the radial direction, so that the first abutment 1212 can restrict the elastic member 14 from disengaging from the transmission part 122 in the axial direction.

[0053] Considering the specific structural scheme of the second abutment portion 112, in the peeling assembly 1 provided in this application embodiment, the second abutment portion 112 includes a second insertion plane 1121 and an extension portion 1122. The second insertion plane 1121 is used to form another part of the structure of the insertion plane C that adapts to the disassembly hole 1A. The extension portion 1122 is used to partially cover the outside of the sliding inner core 12, and the extension portion 1122 is formed on both sides of the cavity bottom surface 1111 of the supporting shell 11 and extends along the height direction of the supporting shell 11. There is a second recessed area 1123 between the second insertion plane 1121 and the extension portion 1122. The second recessed area 1123 facilitates the formation of an L-shaped structure of the second insertion plane 1121. In addition, the second recessed area 1123 is adapted to the first recessed area 1213 so that when the first insertion plane 1211 and the second insertion plane 1121 are flush with the top surface A, the first recessed area 1213 and the second recessed area 1123 together form a clearance space so that the user can perform head retrieval or other operations in a narrow space.

[0054] Considering the connection scheme between the drive component 13 and the transmission part 122, in the stripping assembly 1 provided in this application embodiment, the drive component 13 and the transmission part 122 are connected by threads. During the tightening process, due to the helix angle of the thread and the interaction between the thread teeth, a relative axial displacement tendency is generated between the drive component 13 and the transmission part 122. As the tightening degree increases, this tendency is hindered, thereby generating an axial preload between the two. The magnitude of this preload is closely related to factors such as the type of thread (e.g., ordinary thread, trapezoidal thread, etc.), pitch, and tightening torque. Generally speaking, the smaller the pitch and the larger the tightening torque, the greater the axial preload generated.

[0055] For example, the drive unit 13 can adopt a handle-like structure, which includes a connecting part 131 with a support surface 1311. The connecting part 131 can fit against both the ground and the support housing 11 at the same time, and the suspension handle will not be obstructed.

[0056] For example, the drive component 13 can adopt a spoke-shaped structure with a wavy protrusion on its circumference to increase friction when screwing. The center of the circle is a threaded through hole, which engages with the transmission part 122 (i.e., the threaded part 1222 mentioned later) of the sliding inner core 12 extending out of the support housing 11.

[0057] When a non-axial driving force is applied, such as a circumferential force (e.g., the rotational force of the drive member 13), due to the constraint of the thread, this non-axial force cannot directly cause the transmission part 122 to move in the corresponding direction; the helical structure of the thread causes the circumferential force to be decomposed between the thread teeth; part of the force is along the tangential direction of the thread teeth, causing the thread to rotate relative to each other; the other part of the force is along the axial direction, pushing the transmission part 122 to produce axial movement.

[0058] In summary, the threaded connection between the drive unit 13 and the transmission unit 122, by generating axial preload, changing the direction of force, and realizing axial helical travel, can be adapted to applications in narrow spaces to ensure stable and reliable performance.

[0059] Considering the specific structural scheme of the transmission part 122, in the peeling assembly 1 provided in this application embodiment, the transmission part 122 includes a smooth rod part 1221 and a threaded part 1222 connected to the smooth rod part 1221. The smooth rod part 1221 is used to sleeve the elastic member 14 and pass through the support housing 11. The threaded part 1222 is used to be threadedly connected to the connecting part 131 of the driving member 13. The smooth rod part 1221 is connected to the first abutment platform 1212.

[0060] In this way, the drive component 13 rotates, and through the threaded connection with the threaded part 1222, the rotational motion is converted into the axial linear motion of the transmission part 122; the elastic component 14 is sleeved on the smooth rod part 1221, which can buffer the impact force during the movement and avoid rigid collision damage to the components; the smooth rod part 1221 is connected to the first abutment platform 1212, which can realize the axial positioning of the transmission part 122, prevent its axial movement, improve structural stability, ensure that the entire system can operate smoothly, and ensure transmission accuracy.

[0061] Specifically, the elastic element 14 is usually pre-compressed during installation, which generates a pre-tightening force between the first abutment platform 1212 connected to one end of the smooth rod 1221 and the bottom surface 1111 of the guide groove 111. This pre-tightening force can ensure the tightness of the connection, reduce looseness and gaps, and improve the stability and reliability of the entire transmission system; the pre-tightening force can ensure the stability of the overall structure.

[0062] This application embodiment also provides a peeling device, which may include the aforementioned peeling component 1. It can be applied to any scenario where it is necessary to peel off two structures with opposite joint surfaces using the disassembly hole 1A. It can achieve all the effects of the peeling component 1, which will not be elaborated here.

[0063] The application method of the peeling component or peeling device according to the embodiments of this application is as follows:

[0064] First, the elastic element 14 is fitted onto the smooth rod portion 1221 of the sliding inner core 12.

[0065] Then the transmission part 122 of the sliding inner core 12 is inserted into the support housing 11 through the guide groove 111 of the support housing 11, so that the threaded part 1222 passes out of the support housing 11.

[0066] Next, thread the connecting part 131 of the drive component 13 (handle) together with the threaded part 1222, rotate the handle, and level the top surface of the first insertion plane 1211 of the sliding inner core 12 with the top surface of the second insertion plane 1121 of the supporting outer shell 11 to complete the assembly.

[0067] Finally, after leveling the first insertion plane 1211 and the second insertion plane 1121, the insertion plane formed together is inserted into the disassembly hole 1A. By rotating the handle clockwise (or counterclockwise), the sliding inner core 12 will move along the axial direction of the transmission part 122 in the direction of rotating the handle. At this time, the first insertion plane 1211 and the second insertion plane 1121 will simultaneously apply opposite forces to the oil pan and cylinder block plane of the disassembly hole respectively. When the force is greater than the adhesive force of the oil pan adhesive, the oil pan can be peeled off.
