Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a centering inner support tool for processing shaft parts. Background Art

[0002] Machining precision is a core requirement of the manufacturing industry, especially in the precision machining of shaft parts, where accurate positioning and stable support of the inner hole are crucial. Existing traditional positioning methods rely on complex fixture systems. These methods suffer from complex operation, inaccurate positioning, and poor stability. These methods can easily lead to machining errors, impacting product quality, increasing production costs and time, and making it difficult to adapt to diverse part processing needs. Their limitations are particularly evident in small and medium-volume production. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a centering inner support tool for machining shaft parts.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a centering inner support tool for machining shaft parts, the innovation of which is that it includes a support and an inner support assembly;

[0005] The support includes a cover plate and a base;

[0006] The cover plate is arranged horizontally, and has a center hole at its center, which is used to ensure the accurate positioning of the shaft part with an inner hole to be processed and the structure, and at the same time enables the shaft part with an inner hole to be processed to be perpendicular to the structure;

[0007] The base is horizontally arranged below the cover plate, and the base and the cover plate are coaxial;

[0008] The inner support assembly includes an inner support column and a copper sleeve;

[0009] The inner support column is fixed to the center of the top of the base and forms an L-shaped structure with the base. The inner support column is vertically arranged, and the outer diameter of the inner support column increases from top to bottom;

[0010] The copper sleeve is installed on the base and is located on the circumferential side of the inner support column. It includes an annular sleeve body. The inner wall thickness of the annular sleeve decreases from top to bottom, matching the inner support column. It is used to position and process other surfaces to be processed based on the processed inner hole of the shaft part, thereby achieving more stable fixation and positioning for the shaft parts.

[0011] Furthermore, the cover plate is connected to the base via connecting bolts, and the base and the cover plate are fixed by bolts, and are tightly connected together to achieve positioning using the inner hole that has been processed on the shaft part.

[0012] Furthermore, the annular sleeve is provided with a plurality of first and second vertical slots, the first and second vertical slots being arranged in an alternating pattern, with the first slots extending upward from the bottom end of the annular sleeve and the second slots extending downward from the top end. Assuming the lengths of the first and second vertical slots are the same, a, and the height of the annular sleeve is b, then a = (5 / 6-9 / 10)b. This creates an expansion sleeve structure for the copper sleeve, improving machining efficiency, eliminating pre-machining adjustments, and reducing clamping times. Furthermore, the copper sleeve expands the inner bore of the shaft component, preventing some shaft components from being pressed against their end faces.

[0013] Furthermore, the cover plate and the base are respectively provided with a first screw hole and a second screw hole.

[0014] Furthermore, the extending sides of the first vertical groove and the second vertical groove are both circular.

[0015] The advantages of the present invention are:

[0016] 1. The utility model is a tool used in the field of mechanical processing, especially for precise positioning and internal support of shaft parts with machined inner holes. By tightening the bolts to locate the inner hole and expand the copper sleeve and the inner support column, the inner hole can be quickly and accurately positioned. At the same time, stable support and accurate positioning are provided, solving the problems of fixation and positioning in the processing of shaft parts with machined inner holes, ensuring processing accuracy and stability, improving processing efficiency and product quality, and being cost-effective, suitable for mass production needs.

[0017] 2. The utility model has a simple structure and uses bolts to fix the base and the cover plate, connecting them tightly together to achieve positioning based on the inner hole processed by the shaft parts. It is convenient, fast, easy to operate and maintain.

[0018] 3. The inner support assembly can be tightened manually, which is flexible and can adapt to inner hole shaft parts of different sizes and shapes, reducing processing errors and improving product quality.

[0019] 4. The annular sleeve body is provided with a plurality of first vertical grooves and second vertical grooves, so that the copper sleeve forms an expansion sleeve structure, which can improve processing efficiency, avoid the need for correction of each piece before processing, reduce the number of clamping times, and expand the inner hole of the shaft parts through the copper sleeve to avoid some shaft parts not being allowed to press the end face.

[0025] like Figure 1-4 The illustrated embodiment is a centering inner support tool for machining shaft parts, comprising a support and an inner support assembly.

[0026] The support comprises a cover plate 1 and a base 2.

[0027] The cover plate 1 is arranged horizontally and has a center hole 7 at its center position, which is used to ensure the accurate positioning of the shaft parts with inner holes to be processed and the present structure, while making the shaft parts with inner holes to be processed perpendicular to the present structure.

[0028] The base 2 is horizontally arranged below the cover plate 1 , and the base 2 and the cover plate 1 are coaxial.

[0029] The cover plate 1 and the base 2 are respectively provided with three first screw holes and three second screw holes. The cover plate 1 and the base 2 are connected by three connecting bolts. The base 2 and the cover plate 1 are fixed with bolts and tightly connected together to achieve positioning based on the inner hole processed by the shaft parts.

[0030] The inner support assembly includes an inner support column 3 and a copper sleeve 4.

[0031] The inner support column 3 is fixed at the center of the top of the base 2 and forms an L-shaped structure with the base 2. The inner support column 3 is vertically arranged, and the outer diameter of the inner support column 3 increases from top to bottom.

[0032] The copper sleeve 4 is installed on the base 2 and is located on the circumferential side of the inner support column 3. It includes an annular sleeve body 8. The inner wall thickness of the annular sleeve body 8 decreases from top to bottom, matching the inner support column 3. It is used to position and process other surfaces to be processed based on the processed inner hole of the shaft parts, thereby achieving more stable fixation and positioning for the shaft parts.

[0033] A plurality of first vertical grooves 5 and second vertical grooves 6 are provided on the annular sleeve 8.

[0034] Assuming the lengths of the first and second vertical slots 5 and 6 are the same, both a, and the height of the annular sleeve 8 is b, then a = (5 / 6 to 9 / 10) b. This creates an expansion sleeve structure for the copper sleeve 4, improving machining efficiency, eliminating pre-machining adjustments, and reducing clamping times. Furthermore, the copper sleeve 4 expands the inner bore of the shaft component, preventing some shaft components from being pressed against their end faces.

[0035] A circular groove is also provided in the middle of the circumference of the circular sleeve 8 .
