Abstract
Description
Technical Field
[0001] This application relates to the field of drilling equipment technology, and in particular to a support roller for drilling disc-shaped workpieces and a drilling equipment for disc-shaped workpieces. Background Technology
[0002] In the machining of large disc-shaped workpieces, it is usually necessary to drill a large number of assembly holes on the circumference or end face to meet connection or positioning requirements. Traditional machining methods mainly rely on the indexing rotary table of a special machine tool for drilling. However, since the size of the rotary table is fixed, when the workpiece diameter is large, some areas may be suspended beyond the support range, resulting in insufficient rigidity during drilling and easy workpiece vibration. This can cause problems such as deviations in hole diameter and position or substandard hole wall roughness.
[0003] In existing technologies, although auxiliary support devices can be used, most of them have complex structures and are inconvenient to adjust, making it difficult to balance indexing flexibility and locking stability. Utility Model Content

[0037] Reference Figure 1 , Figure 2 An embodiment of this application provides a support roller 1 for drilling disc-shaped workpieces, comprising:
[0038] A support sleeve 11 is provided, and a threaded hole 111 is provided at the bottom of the support sleeve 11.
[0039] The positioning rotary assembly 12 is sleeved inside the support slide sleeve 11, and the positioning fixture 3 can slide on the top of the positioning rotary assembly 12.
[0040] Adjusting bolt 13 is screwed into threaded hole 111, and the positioning rotary assembly 12 slides in support sleeve 11 by adjusting bolt 13.
[0041] Specifically, the support sleeve 11 is a hollow structure with an open top. A threaded hole 111 is made at the bottom, wherein the threaded hole 111 and the support sleeve 11 are on the same central axis. In this way, when the adjusting bolt 13 supports the positioning rotary assembly 12, the force is balanced and the support is stable.
[0042] The positioning and rotating assembly 12 is used to support the positioning fixture 3 and to enable the positioning fixture 3 to rotate flexibly when drilling and indexing disc-shaped workpieces.
[0043] Part of the positioning rotary assembly 12 is fitted inside the support sleeve 11, and can slide up and down inside the sleeve by adjusting the bolt 13 to ensure that the positioning fixture 3 is stably supported.
[0044] In use, the support roller for drilling disc-shaped workpieces provided in this embodiment is fixed on the rotary table 2 of the disc-shaped tool drilling equipment. The positioning fixture 3 is supported and stabilized by adjusting the bolt 13, thereby supporting the disc-shaped workpiece stably. When the rotary table 2 rotates and indexes, the positioning fixture 3 slides smoothly on the positioning rotary assembly 12 to achieve the function of support and positioning.
[0045] The support roller for drilling disc-shaped workpieces provided in this embodiment has an adjustable support function by adjusting the positioning and rotating assembly, which moves up and down within the support sleeve via adjusting bolts. The positioning fixture can be easily rotated through the positioning and rotating assembly, which facilitates indexing adjustment, simplifies clamping and leveling, greatly shortens clamping time, and ensures the stability of large disc-shaped workpieces. It also makes drilling smooth, greatly improving drilling efficiency and drilling quality.
[0046] In one embodiment, the positioning rotation component 12 includes:
[0047] Support roller seat 121 is sleeved inside support sliding sleeve 11;
[0048] The roller support 122 is fixed on the side of the support roller seat 121 away from the support sleeve 11, and the positioning fixture 3 can slide on the top of the roller support 122.
[0049] Specifically, the support roller seat 121 can slide up and down within the support sleeve 11 via the adjusting bolt 13. The support roller seat 121, the adjusting bolt 13, and the support sleeve 11 all share the same central axis. The roller support 122 can be welded to the top surface of the support roller seat 121.
[0050] In one embodiment, the roller support 122 includes:
[0051] Two bearing housings 1221 are fixed on the roller support 122;
[0052] A self-aligning ball bearing 1222 is disposed between two bearing housings 1221; the positioning fixture 3 can slide on the surface of the self-aligning ball bearing 1222.
[0053] Roller 1223 passes through one bearing housing 1221, self-aligning ball bearing 1222, and another bearing housing 1221 in sequence.
[0054] Nut 1224 is fitted onto the end of roller 1223.
[0055] Specifically, two bearing seats 1221 are fixedly welded to the top surface of the roller support 122. The two bearing seats 1221 are used to support the roller 1223 and the self-aligning ball bearing 1222. The self-aligning ball bearing 1222 can rotate flexibly on the roller 1223 so that the positioning fixture 3 can rotate flexibly on the surface of the self-aligning ball bearing 1222 during workpiece drilling indexing. The nut 1224 is used to fix the roller 1223 after drilling indexing is completed.
[0056] In one embodiment, the roller support 122 further includes:
[0057] A gasket 1225 is disposed between a nut 1224 and another bearing housing 1221. The area of the gasket 1225 is larger than that of the nut 1224 to increase the contact area and distribute the pressure.
[0058] In one embodiment, the roller support 122 further includes:
[0059] A retaining ring 1226 is disposed between the self-aligning ball bearing 1222 and the bearing housing 1221. The retaining ring 1226 prevents the self-aligning ball bearing 1222 from moving unintended in the axial direction.
[0060] In one embodiment, the support roller for drilling the disc-shaped workpiece further includes:
[0061] Locking bolt 14 is used to fix the support sleeve 11 and the positioning rotary assembly 12.
[0062] Specifically, once the position of the positioning and rotating assembly 12 is adjusted to the correct position, the support sleeve 11 and the positioning and rotating assembly 12 can be fixed by the locking bolt 14 to prevent the positioning and rotating assembly 12 from slipping off.
[0063] A through hole can be made in the side wall of the support sleeve 11, and the locking bolt 14 passes through the through hole to fix the support sleeve 11 and the positioning rotation assembly 12.
[0064] like Figure 3 As shown in the illustration, this application also discloses a drilling device for disc-shaped workpieces, comprising:
[0065] Support rollers for drilling disc-shaped workpieces, as provided in any of the above embodiments;
[0066] Rotary worktable 2, the support sleeve 11 of the support roller for drilling disc-shaped workpieces is fixedly installed on the rotary worktable 2, and the rotary worktable 2 has a through hole that matches the adjusting bolt 13.
[0067] Positioning fixture 3 adjusts the position of the positioning rotary assembly 12 of the support roller for drilling disc-shaped workpieces to support positioning fixture 3 and allow positioning fixture 3 to slide on the top of positioning rotary assembly 12.
[0068] By using the support rollers for drilling disc-shaped workpieces, the positioning fixture 3 can be easily rotated by the positioning rotary assembly 12, which facilitates indexing adjustment. This solves the problem of disc-shaped workpieces easily vibrating when drilling due to the small rotary table 2 and the large workpiece, greatly improving drilling efficiency and drilling quality.
[0069] In one embodiment, at least three support rollers for drilling disc-shaped workpieces are included. For example, four support rollers for drilling disc-shaped workpieces are evenly distributed circumferentially on the rotary table 2.
[0070] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
