Technical Field

[0001] This application relates to the field of auxiliary tooling technology for boring machine processing, specifically an auxiliary tooling for machining large rotating parts. Background Technology

[0002] Large rotating parts are common key components in the machinery manufacturing industry, typically referring to workpieces with large diameters or lengths (reaching several meters or even tens of meters) that require rotational machining around a central axis. When machining these large rotating parts, their enormous size, coupled with the limitations of boring machines (which are open-type machine tools with only four axes), makes conventional fixing and machining methods unsuitable for rotating parts exceeding four axes. Therefore, this application proposes an auxiliary tooling for machining large rotating parts to address this problem. Summary of the Invention

[0003] The technical problem to be solved by this application is to overcome the existing defects and provide an auxiliary tooling for machining large rotating parts, which can effectively solve the problems in the background art.

[0005] Furthermore, the adjustment assembly includes a screw, a threaded sleeve, a bottom shell, and a drive assembly. The number of threaded sleeves is four, and the four threaded sleeves are evenly distributed on the support base.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-3 This application provides a technical solution for auxiliary tooling for machining large rotating parts: an auxiliary tooling for machining large rotating parts, including a rotating workpiece 1, with four supporting tooling 2 at the bottom of the rotating workpiece 1.

[0018] Specifically, the four support fixtures 2 can provide stable support for the rotating workpiece 1 and assist the rotating workpiece 1 in rotating, thereby facilitating the boring machine to process the rotating workpiece 1.

[0019] The four support fixtures 2 can adjust their spacing according to the size of the rotating workpiece 1, meeting the processing requirements of rotating workpieces 1 of different sizes. At the same time, the height of each support fixture 2 can be flexibly adjusted through the use of the adjustment group 5 to adapt to various height requirements during the processing, ensuring the stability and accuracy of processing large rotating parts.

[0020] The support fixture 2 includes an auxiliary roller group 3, a support seat 4, and an adjustment group 5. The auxiliary roller group 3 is in contact with the bottom of the rotating workpiece 1. The support seat 4 is provided on the lower surface of the auxiliary roller group 3, and the adjustment group 5 is provided at the bottom of the support seat 4.

[0021] Specifically, by setting up the auxiliary roller group 3, the necessary auxiliary support can be provided for the rotating workpiece 1. At the same time, with the help of the auxiliary roller group 3, the rotating workpiece 1 can rotate smoothly. The support seat 4 and the adjustment group 5 can support the auxiliary roller group 3.

[0022] More specifically, the support base 4 mainly consists of a column, an upper top plate, and a lower bottom plate. The column supports the auxiliary roller group 3. The upper top plate is connected to the mounting base 18 on the auxiliary roller group 3 by bolts to ensure the stability of the support. The lower bottom plate is connected to the adjustment group 5. The adjustment group 5 adjusts the height of the auxiliary roller group 3 precisely by adjusting the screw 6 so that the rotating workpiece 1 can obtain the best support effect.

[0023] Furthermore, the adjustment group 5 includes a screw 6, a threaded sleeve 7, a bottom shell 8, and a drive group 9. There are four threaded sleeves 7, which are evenly distributed on the support base 4. The bottom shell 8 is provided at the bottom of the support base 4, and the threaded sleeves 7 are rotatably connected to the support base 4 and the bottom shell 8. The screw 6 is provided inside the threaded sleeve 7, and a pad is provided at the bottom of the screw 6. The drive group 9 is provided between the support base 4 and the bottom shell 8.

[0024] Specifically, the upper and lower base plates of the support base 4 are connected to the bottom shell 8 by bolts. The threaded sleeve 7 is vertically installed on the support base 4 and the bottom shell 8, and the threaded sleeve 7 is engaged with the screw 6 by threads. Under the drive of the drive group 9, it can be raised and lowered to adjust the height of the support base 4.

[0025] Furthermore, the drive assembly 9 includes a connecting gear 10, a driving gear 11, driven gears 12, and a connecting shaft 13. The connecting gear 10 is disposed between the support base 4 and the bottom shell 8, and is rotatably connected to the support base 4 and the bottom shell 8 via a rotating shaft. Four driven gears 12 are disposed on the outer side of the connecting gear 10, and the driven gears 12 are fixed on the threaded sleeve 7. A driving gear 11 is disposed between two adjacent driven gears 12, and the driving gear 11 meshes with the connecting gear 10. The driving gear 11 is rotatably connected to the support base 4 and the bottom shell 8 via the connecting shaft 13.

[0026] Specifically, the connecting gear 10 can connect the driving gear 11 with the four driven gears 12, thereby transmitting the rotational power of the driving gear 11 to the four driven gears 12. The driven gears 12 then drive the threaded sleeve 7 to rotate synchronously, thereby causing the screw 6 to move up and down and adjusting the height of the auxiliary roller group 3.

[0027] Furthermore, an internal hexagonal groove 14 is provided at the top of the connecting shaft 13.

[0028] Specifically, by inserting a hex wrench into the internal hex socket 14 and then rotating the hex wrench, the connecting shaft 13 is rotated, thereby causing the drive gear 11 to rotate. The drive gear 11 transmits power to the connecting gear 10, which in turn drives the four driven gears 12 to rotate synchronously with the threaded sleeve 7, thus achieving precise lifting and lowering adjustment of the screw 6.

[0029] The auxiliary roller assembly 3 includes a support roller 15, a bearing 16, a central shaft 17, and a mounting base 18. The support roller 15 is rotatably connected to the central shaft 17 through two bearings 16, and the two ends of the central shaft 17 are fixed on the mounting base 18.

[0030] Furthermore, the mounting base 18 includes a radial cover and a lower base. The upper surface of the lower base is provided with a radial cover for fixing the central shaft 17. The central shaft 17 is fixed by the cooperation between the radial cover and the lower base.

[0031] Furthermore, the support roller 15 includes an outer roller and spacers. The outer roller has two spacers for mounting bearings 16 inside, and a cap for fixing the bearings 16 is provided on the outside of the spacers.

[0032] In use: The spacing of the four support fixtures 2 is adjusted according to the size of the rotating workpiece 1 to meet the processing requirements of rotating workpieces 1 of different sizes. At the same time, a hex wrench is inserted into the internal hexagonal groove 14 and then rotated, causing the connecting shaft 13 to rotate, thereby rotating the drive gear 11. The drive gear 11 transmits power to the connecting gear 10, causing the connecting gear 10 to drive the four driven gears 12 to rotate synchronously with the threaded sleeve 7, realizing the raising and lowering of the screw 6, thereby adjusting the height of the auxiliary roller group 3. The four support rollers 15 support the rotating workpiece 1, thus facilitating the boring machine to process the rotating workpiece 1.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
