[0004] Therefore, the application provides a self-adaptive inner support head for different diameters to solve the above problems. UTILITY MODEL CONTENTS
[0005] In order to solve the above problems, the application provides a self-adaptive inner support head for different diameters.
[0006] The self-adaptive inner support head for different diameters provided by the application adopts the following technical scheme:
[0007] A self-adaptive inner support head for different diameters comprises:
[0008] A shell is provided with a sliding member inside the shell, and a connecting rod outside the shell range is arranged on the left side of the sliding member;
[0009] A slide rail is arranged around the sliding member, and the slide rail is arranged in a horn shape.

[0011] Further, the sliding member is a wedge structure, and the inclination direction of the slide rail is consistent with the inclination direction of the sliding member.
[0012] Through the technical scheme, force transmission and conversion are more smooth and efficient. When the sliding member moves along the axial direction, due to the cooperative action of the wedge-shaped structure and the slide rail, the horizontal force can be converted into the vertical movement force of the support block in a relatively stable and predictable manner, reducing the jamming and energy loss during movement; when adapting to different diameter inner holes, the extension length of the support block can be more accurately controlled, improving the precision and stability of the inner support, which can significantly improve the product quality and production efficiency, and reduce the scrap rate and rework rate in precision machining or assembly process with high precision requirements.

[0014] Through the technical scheme, good guidance and limiting effect are provided for the movement of the sliding block. On the one hand, the waist-shaped hole limits the movement of the sliding block within a specific path range, avoiding the deviation of the sliding block from the track or excessive shaking during movement, thereby ensuring the accuracy and stability of the movement of the support block, so that the inner support head can always maintain a reliable inner support state during work.
[0015] Further, the number of slide rails is at least three and is uniformly distributed.
[0016] Through the technical scheme, the uniform distribution design enables the support block to uniformly disperse the pressure when subjected to force, ensuring that the inner support head can provide stable and balanced support force in different diameter inner holes; when dealing with inner support tasks with a large diameter variation range, no matter how irregular the inner hole shape is or how complex the stress condition is, multiple uniformly distributed support blocks can work cooperatively to effectively prevent the damage of the inner support head or the deformation of the inner hole caused by local stress concentration.
[0017] Further, the sliding member and the slide rail are an integral molded structure.
[0018] Through the technical scheme, the integral molded structure can avoid structural damage caused by stress concentration at the connection part during force conduction, ensuring that the force can be uniformly and smoothly transmitted between the sliding member and the slide rail, thereby accurately controlling the movement of the support block and improving the inner support precision and stability.

[0029] Embodiments:
[0030] The following will be further described in detail in combination with the accompanying drawings Figure 1 to make a further detailed description of the present application.
[0031] The embodiments of the present application disclose an inner support head self-adapting to different diameters, comprising:
[0032] A shell 1, a sliding piece 2 is slidingly arranged in the shell 1, and a connecting rod 3 outside the range of the shell 1 is horizontally arranged on the left side of the sliding piece 2;
[0033] A slide rail 4 is circumferentially arranged on the sliding piece 2, and the slide rail 4 is horn-shaped and obliquely arranged;
[0034] A support block 5, the bottom of the support block 5 is slidingly connected with the slide rail 4, and the support block 5 longitudinally slides through the shell 1.
[0035] Referring to Figure 2 , Figure 3 and Figure 4 , the sliding piece 2 is a wedge-shaped structure, the oblique direction of the slide rail 4 is consistent with the oblique direction of the sliding piece 2; the force transmission and conversion are more smooth and efficient. When the sliding piece 2 moves along the axial direction, due to the synergistic effect of the wedge-shaped structure and the slide rail 4, the horizontal force can be converted into the vertical movement force of the support block 5 in a relatively stable and predictable manner, reducing the jamming and energy loss in the movement process; when adapting to different diameter inner holes, the extension length of the support block 5 can be more accurately controlled, the precision and stability of the inner support are improved, whether in precision machining or in assembly process with high precision requirement, the product quality and production efficiency can be significantly improved, and the scrap rate and rework rate can be reduced.
[0036] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4The waist-shaped hole is provided on the shell 1, and the support block 5 is matched with the waist-shaped hole in size; the waist-shaped hole provides good guidance and limiting effect for the movement of the sliding block. On the one hand, the waist-shaped hole limits the movement of the sliding block within a specific path range, avoids the deviation of the sliding block from the track or the excessive shaking of the sliding block during the movement, and thus ensures the accuracy and stability of the movement of the support block 5, so that the inner support head can always maintain a reliable inner support state during work.
[0037] Referring to Figure 2 , Figure 3 and Figure 4 , the number of slide rails 4 is at least three and is uniformly distributed; the uniform distribution design enables the support block 5 to uniformly disperse the pressure when being stressed, so as to ensure that the inner support head can provide stable and balanced support force in different diameter inner holes; when coping with the inner support task of a large diameter change range, no matter how irregular the shape of the inner hole is or how complex the stress condition is, the multiple uniformly distributed support blocks 5 can work cooperatively to effectively prevent the damage of the inner support head or the deformation of the inner hole caused by local stress concentration.
[0038] Referring to Figure 2 , Figure 3 and Figure 4 , the sliding member 2 and the slide rail 4 are an integrally formed structure; the integrally formed structure can avoid the structural damage caused by stress concentration at the connecting position during force transmission, ensure that the force can be uniformly and smoothly transmitted between the sliding member 2 and the slide rail 4, and thus accurately control the movement of the support block 5, improve the inner support precision and stability.
[0039] The implementation principle of the inner support head of the present application which is self-adaptable to different diameters is as follows:
[0040] The sliding member 2 can move left and right along the axis direction of the shell 1, and the horn-shaped inclined slide rail 4 arranged around the surface of the sliding member 2 is in sliding connection with the bottom of the support block 5. When the sliding member 2 moves to the left, the support block 5 will stretch out outward along the direction perpendicular to the axis direction due to the action of the inclined surface of the slide rail 4; when the sliding member 2 moves to the right, the support block 5 will contract inward along the perpendicular direction; by setting different axis strokes of the sliding member 2, the length of the support block 5 that stretches out can be controlled, so as to adapt to the support requirements of different diameter inner holes.
[0041] The overall structural design of the present application not only ensures efficient adaptation to different diameter inner holes, but also focuses on the cooperative work and mechanical property optimization between components, such as the cooperation of the wedge-shaped sliding member 2 and the inclined slide rail 4, the uniform distribution of the multiple slide rails 4, and the integrally formed structure. These designs not only improve the precision and stability of the inner support, but also enhance the rigidity and durability of the inner support head, reduce the equipment failure rate and maintenance cost, and provide reliable technical support for high-precision and high-efficiency production operations in related industrial fields.
[0042] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
