[0024] In order to better explain the present invention, and to facilitate understanding, the following Figure 1-8 , through the specific implementation method, the utility model is described in detail. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 3 The orientation is referenced.

[0025] Example 1:

[0026] Reference Figures 1-8 , an embodiment of the present invention provides a cylindrical steel support upper pendulum processing tool, a first positioning surface 101 is formed on the cylindrical steel support upper pendulum 1, the first positioning surface 101 is opposite to the arc-shaped surface to be processed 104, and is located on one side of the thickness direction of the cylindrical steel support upper pendulum 1, the processing tool includes a core shaft 2, a first positioning component 3 and a locking piece 4; the first positioning component 3 is connected to the core shaft 2, and a plurality of first base surfaces 301 are formed on the first positioning component 3, each first base surface 301 extends axially along the core shaft 2, and can be fitted with the first positioning surface 101 of a cylindrical steel support upper pendulum 1, and the cylindrical steel support upper pendulum 1 is locked on the first base surface 301 by the locking piece 4; all the first base surfaces 301 are arranged symmetrically along the axis center of the core shaft 2, so that the contours of the surfaces to be processed 104 of all cylindrical steel support upper pendulums 1 locked on all the first base surfaces 301 are spliced ​​to form a cylindrical surface coaxial with the core shaft 2.

[0027] In this embodiment, the core shaft 2 is the central axis of the entire tooling, used to ensure the alignment and stability of all components.

[0028] The first positioning assembly 3 is connected to the core shaft 2 and has multiple first base surfaces 301 formed thereon. The first base surfaces 301 are symmetrically arranged along the axis of the core shaft 2 and extend axially along the core shaft 2. The first base surfaces 301 are designed to closely mate with the first positioning surface 101 on the cylindrical steel support upper pendulum 1, thereby achieving reliable positioning.

[0029] When the cylindrical steel support upper pendulum 1 is placed on the fixture, the first positioning surface 101 aligns with the first base surface 301. The locking member 4, which can be a locking bolt, clamp, or other mechanical locking device, securely secures the cylindrical steel support upper pendulum 1 to the fixture. Because these base surfaces are centrally symmetrical about the axis of the mandrel 2, when machining cylindrical steel support upper pendulums 1 with identical structures, all cylindrical surfaces can be machined in a single turning operation, significantly improving machining efficiency.

[0030] In this embodiment, the locking member 4 includes one or more locking bolts, one or more process holes 105 are opened on the upper pendulum 1 of the cylindrical steel support, and one or more locking bolt holes 302 are opened on the first base surface 301. The corresponding locking bolts pass through the corresponding process holes 105 and are connected to the corresponding locking bolt holes 302.

[0031] A conical surface is provided on the upper portion of the locking bolt, and the side of the process hole 105 facing the conical surface is a conical hole. After the locking bolt is tightened, the conical hole matches the conical surface.

[0032] The locking piece 4 can be set as a locking bolt with a tapered surface, and the part of the process hole 105 that cooperates with the locking bolt is a tapered hole, which is matched with a high-precision fine thread to achieve the positioning of the cylindrical steel support upper pendulum 1 on the tooling.

[0033] When the locking bolt is tightened, the tapered hole mates with the tapered surface. This tapered-hole fit provides additional positioning and stability, ensuring that the cylindrical steel support upper pendulum 1 remains precisely positioned when locked, while minimizing movement caused by vibration or other external forces. Simply tightening the locking bolt secures and unlocks the upper pendulum, facilitating assembly and disassembly of the cylindrical steel support upper pendulum 1.

[0034] Example 2:

[0035] Reference Figure 1-7 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0036] A second positioning surface 102 is also formed on the cylindrical steel support upper pendulum 1. The second positioning surface 102 is perpendicular to the first positioning surface 101 and is formed on one side of the width direction of the cylindrical steel support upper pendulum 1. A second base surface 303 is also formed on the first positioning component 3, which is symmetrical along the axis of the core shaft 2 and perpendicular to the axis of the core shaft 2. The second base surface 303 can be fitted with the second positioning surface 102.

[0037] The first positioning assembly 3 includes several side plates 31 and ribs 32 connecting adjacent side plates 31. At least two side plates 31 are provided with an L-shaped groove on the side away from the core shaft 2. The two intersecting side walls of the L-shaped groove form a first base surface 301 and a second base surface 303 respectively.

[0038] A third positioning surface 103 is also formed on the upper pendulum 1 of the cylindrical steel support. The third positioning surface 103 is perpendicular to the first positioning surface 101. The third positioning surface 103 is formed on one side of the length direction of the upper pendulum 1 of the cylindrical steel support; the processing tooling also includes a second positioning component connected to the core shaft 2. The second positioning component forms a third base surface that is symmetrical along the axis of the core shaft 2 and perpendicular to the axis of the core shaft 2. The third base surface can fit with the third positioning surface 103.

[0039] The second positioning assembly includes a vertical plate, which is connected to the core shaft 2 and is located on the axial side of the first positioning assembly 3 along the core shaft 2. The vertical plate forms a third base surface with a plane facing the first positioning assembly 3. The vertical plate includes a body and a plurality of positioning blocks connected to the body and symmetrically distributed along the axis of the core shaft 2. The body is connected to the core shaft 2, and the positioning blocks form a third base surface with a plane facing the first positioning assembly 3. The positioning blocks are detachably connected to the body.

[0040] In this embodiment, the second positioning surface 102 is perpendicular to the first positioning surface 101 and is located on one side in the width direction of the cylindrical steel support upper pendulum 1. The first positioning surface 101 is aligned with the second base surface 303 of the first positioning component 3.

[0041] The third positioning surface 103 is also perpendicular to the first positioning surface 101, but is located on one side of the length direction of the cylindrical steel support upper pendulum 1. This surface is aligned with the third base surface of the second positioning component.

[0042] The first positioning assembly 3 includes several side panels 31 and ribs 32 connecting adjacent side panels 31. At least two side panels 31 are provided with L-shaped grooves to ensure that the first base surface 301 and the second base surface 303 have sufficient extended area, ensuring stability during the positioning process. The two intersecting sidewalls of this L-shaped groove respectively form the first base surface 301 and the second base surface 303. This L-shaped groove simultaneously forms the first base surface 301 and the second base surface 303, reducing the difficulty of forming the first base surface 301 and the second base surface 303 while also ensuring the compactness and simplicity of the first positioning assembly 3.

[0043] The ribs 32 connect the adjacent side plates 31 , thereby ensuring the integrity and stability of the first positioning assembly 3 .

[0044] The second positioning assembly includes a vertical plate, which is connected to the core shaft 2 and is located on the axial side of the first positioning assembly 3 along the core shaft 2. The vertical plate includes a main body and a plurality of positioning blocks. These positioning blocks are symmetrically distributed along the axis of the core shaft 2 and are connected to the main body. The plane of the positioning block facing the first positioning assembly 3 forms a third base surface, and this third base surface is in contact with the third positioning surface 103 of the upper pendulum 1 of the cylindrical steel support. The combined vertical plate can improve the setting flexibility of the second positioning assembly. When the position of the third base surface needs to be changed, the positioning blocks of different thicknesses can be replaced, thereby greatly improving the flexibility of use of the tooling.

[0045] The locking bolt can pass through the process hole 105 of the upper pendulum 1 of the cylindrical steel support and the locking bolt hole 302 on the tooling to achieve fixation.

[0046] In this embodiment, by aligning the first, second, and third positioning surfaces 101, 102, and 103 with the corresponding base surfaces of the fixture, multi-faceted positioning of the cylindrical steel support upper pendulum 1 can be achieved, greatly improving the accuracy, stability, and convenience of positioning and fixing. Furthermore, the fixture has a compact structure, does not add excessive complexity or weight, and reduces the overall cost of the fixture.

[0047] Example 3:

[0048] Reference Figure 6 In addition to all the technical solutions of the above-mentioned embodiment 2, the embodiment of the present utility model further has the following technical solutions:

[0049] A clearance groove 304 is also provided on the first base surface 301 , and the clearance groove 304 is connected to the second base surface 303 to make way for the burr position of the pendulum 1 on the cylindrical steel support.

[0050] In this embodiment, considering that there may be burrs or protrusions on the cylindrical steel support upper pendulum 1, the design of adding a clearance groove 304 on the L-shaped groove can effectively avoid interference between these burrs or protrusions and the tooling, thereby improving the assembly accuracy and convenience of the cylindrical steel support upper pendulum 1 on the tooling, and avoiding damage to the tooling that may be caused by direct collision between the burrs or protrusions and the tooling, thereby extending the service life of the tooling.
