Description

Technical Field

[0001] The utility model relates to the technical field of machining devices for thin-walled ring parts, in particular to an internal support tooling for machining basic thin-walled ring parts. Background Technique

[0002] The basic thin-walled ring part is a common mechanical part. The internal support tooling can effectively support the basic thin-walled ring part and ensure its stability during the machining process.

[0003] In an existing internal support tooling, several cylinders are usually arranged along the circumference on the workbench, and the inner wall surface of the basic part is directly abutted by the extension of the piston rod of the cylinder, so as to achieve the purpose of internal support.

[0004] However, in such an internal support tooling, the basic part needs to be centered and placed on the workbench first to ensure that the piston rods of multiple cylinders can simultaneously abut against the inner wall surface of the basic part; and the movement stroke of the piston rod of the cylinder is single, which is not applicable to basic parts with different inner diameters. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides an internal support tooling for machining basic thin-walled ring parts, and its purpose is to improve the internal support clamping efficiency and application range of basic thin-walled ring parts.

[0006] In order to achieve the above invention purpose, the technical solution adopted by the utility model is as follows:

[0007] Provide an internal support tooling for machining basic thin-walled ring parts, including: a main body, vertically installed on the workbench and hollow inside; a lead screw, rotatably arranged inside the main body; a driving component, installed on the lead screw through screw thread transmission; a conical inclined surface, arranged on the driving component; a guide rod, parallel to the lead screw and installed inside the main body and passing through the driving component; several support components, arranged in a circumferential array and slidably arranged on the main body, one end for abutting against the wall surface of the basic part and the other end abutting against the conical inclined surface; a driving motor, used to drive the lead screw to rotate.

[0008] Further, the internal support tooling further includes: a limit block, arranged on the support component; a return spring, sleeved on the driving component, one end abutting against the main body and the other end abutting against the limit block.

[0009] Further, the internal support tooling further includes: a support block, arranged at one end of the support component far from the driving component and extending along the height direction of the basic part; several abutting blocks, detachably installed on the support block in the vertical direction, and an arc surface is arranged on the abutting block.

[0010] Further, a first thread section and a second thread section with opposite helix directions are provided on the lead screw; the driving components include: a first driving component mounted on the first thread section and a second driving component mounted on the second thread section.

[0011] Further, a sliding sleeve is provided inside the driving component, and the guiding rod is slidably arranged inside the sliding sleeve.

[0012] The beneficial effects of the present utility model are as follows: in the present utility model, a plurality of supporting components are arranged in a circumferential array. During the process of extending out of the main body, the supporting components can slowly abut against the inner wall surface of the base component and center the base component, eliminating the need for manual centering in advance, and effectively improving the inner support clamping efficiency of thin-walled ring-shaped base components; by driving the supporting plate component to extend with a driving motor, the distance that the driving component moves along the guiding rod can be controlled by controlling the number of turns of the driving motor, thereby changing the length of the supporting component pushed out to meet the inner support requirements of base components with different inner diameters and improving the applicable range.

[0018] In specific use, directly sleeved the thin-walled ring-shaped base part to be processed outside the main body 1, then start the driving motor 6, drive the lead screw 2 to rotate through the driving motor 6, and restrict the rotation of the driving component through the guide rod 4, guiding the driving component to translate along the axial direction of the guide rod 4, thereby driving the conical inclined surface 33 to push the supporting component 5 to extend out of the main body 1 until it abuts against the inner wall surface of the base part, completing the inner support work of the base part.

[0019] In the present utility model, a plurality of supporting components 5 are arranged in a circumferential array. During the process of the supporting component 5 extending out of the main body 1, it can slowly abut against the inner wall surface of the base part and center the base part, eliminating the need for manual centering in advance, and effectively improving the inner support clamping efficiency of the thin-walled ring-shaped base part; driving the supporting plate component to extend through the driving motor 6 can control the distance that the driving component moves along the guide rod 4 by controlling the number of turns of the driving motor 6 rotating, thereby changing the length of the supporting component 5 pushed out to meet the inner support requirements of base parts with different inner diameters and expanding the applicable range.

[0020] It can be understood that the lead screw 2 can be rotatably installed on the main body 1 through a bearing, and the driving motor 6 and the lead screw 2 can be connected by gear transmission.

After the driving component moves in the direction away from the supporting component 5, the return spring 52 can push the supporting component 5 to move in the direction away from the base part and retract back into the main body 1 again, facilitating the replacement of the base part.

[0022] Specifically, the inner support tooling further includes: a support block 53, arranged at one end of the supporting component 5 away from the driving component, extending along the height direction of the base part; a contact block 54, along the vertical direction, a plurality of contact blocks 54 are detachably installed on the support block 53, and an arc surface is arranged on the contact block 54.

[0023] In this embodiment, contact blocks 54 are arranged at different horizontal heights to provide support at different horizontal heights and ensure the inner support stability of the base part; among them, the contact blocks 54 can be detachably installed on the support block 53 through screws, facilitating the replacement of contact blocks 54 with different sizes.

[0024] Specifically, a first thread section and a second thread section with opposite helix directions are provided on the lead screw 2; the driving components include: a first driving component 31 mounted on the first thread section and a second driving component 32 mounted on the second thread section; by driving the rotation of the lead screw 2 with a driving motor 6, the first driving component 31 and the second driving component 32 can be driven to move towards / away from each other along the guide rod 4, respectively driving the two support components 5 to move; the first driving component 31 and the second driving component 32 can be mounted between the two support components 5, improving the space utilization rate and making the whole device more compact.

[0025] Further, a sliding sleeve 34 is provided inside the driving component, and the guide rod 4 is slidably arranged inside the sliding sleeve 34. By slidingly contacting the guide rod 4 through the sliding sleeve 34, the wear of the guide rod 4 can be reduced and the service life of the guide rod 4 can be prolonged.
