Technical Field
[0001] This utility model relates to the field of processing tooling technology, and in particular to a processing device for a universal joint copper sliding plate of a ring rolling mill. Background Technology
[0002] A ring rolling mill is a specialized piece of equipment used to manufacture seamless ring-shaped parts, such as bearing rings on a conventional lathe. Please refer to [link / reference]. Figures 1 to 3 The copper sliding bearing of the universal joint in the ring rolling mill has wedge-shaped surfaces 12 at 45° on both sides and a boss 13 in the middle. The boss 13 has a mounting and positioning hole 11. The boss 13 and the mating surfaces 14 on both sides of the boss 13 are coaxial arc surfaces.
[0003] Since these copper sliding tiles are used in pairs, it is necessary to control the radius of the arc surface, the width and position of the boss of the two copper sliding tiles. Therefore, the best solution is to process the two copper sliding tile blanks together. However, the two copper sliding tile blanks cannot be directly installed on the lathe for processing.
[0004] Therefore, a processing device is needed to solve the above problems. Utility Model Content

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] Please see Figures 4 to 10 The universal joint copper sliding bearing processing device of the ring rolling mill of this utility model includes a bearing 2, a positioning mandrel 3, and four wedge-shaped pressure blocks 4. The following is a description of the use of this processing device.
[0028] like Figure 6 As shown, the axle 2 includes two locating planes 21 and a locating mandrel hole 24. During the machining process, the axle blank is first clamped onto a lathe and machined in a double-flat position, forming locating planes 21 at the upper and lower ends of the axle blank. Then, a drilling machine vertically penetrates the middle of the two locating planes 21 to form the locating mandrel hole 24. Furthermore, the aforementioned double-flat position machining can be performed in the middle of the axle 2, forming first frustums 22 at both ends of the axle 2.
[0029] like Figure 7 and Figure 8As shown, the aforementioned positioning mandrel 3 is inserted into the positioning mandrel hole 24 with an interference fit, and the positioning mandrel 3 protrudes from the positioning plane 21 by the same distance. Next, the axle 2 is installed on the lathe. Specifically, a second frustum 23 can be machined outside the first frustum 22. The left second frustum 23 is held by the lathe chuck 5, and the right second frustum 23 is pressed by the live center 6, so that the axle 2 is stably installed and the axis of the axle 2 is aligned with the axis of the lathe.
[0030] like Figure 8 and Figure 10 As shown, after installing the axle 2, a copper sliding tile blank 1 is interference-fitted onto the upper end of the positioning mandrel 3 with its mounting positioning hole 11. Next, two wedge-shaped pressure blocks 4 are pressed against both ends of the copper sliding tile blank 1, ensuring a tight fit between the bottom surface of the copper sliding tile blank 1 and the positioning plane 21. It should be noted that the copper sliding tile blank 1 is a blank with the wedge-shaped surface 12 and mounting positioning hole 11 already machined.
[0031] Specifically, such as Figure 9 As shown, the inclination angle of the driving surface 41 of the wedge-shaped pressure block 4 is consistent with the inclination angle of the wedge-shaped surface 12 of the copper sliding tile blank 1. A bolt countersunk hole 42 is provided in the middle of the wedge-shaped pressure block 4, and bolt holes 25 are provided on the two positioning planes 21 near the first truncated cone 22. A clamping bolt 43 passes through the bolt countersunk hole 42 and connects to the bolt hole 25. As the clamping bolt 43 is screwed in, the positioning surface of the wedge-shaped pressure block 4 slides downward along the inner wall of the first truncated cone 22, and the driving surface 41 of the wedge-shaped pressure block 4 slides relative to the wedge-shaped surface 12 of the copper sliding tile blank 1, thereby pressing the copper sliding tile blank 1 downward, so that the bottom surface of the copper sliding tile blank 1 is tightly engaged with the positioning plane 21. The aforementioned first truncated cone 22 can limit the stroke of the wedge-shaped pressure block 4 and prevent the wedge-shaped pressure block 4 from moving along the axis of the bearing shaft 2, ensuring the processing position of the copper sliding tile blank 1.
[0032] By setting the bolt countersunk hole 42, the clamping bolt 43 can be lower than the wedge-shaped pressure block 4, avoiding collision with the machining tool 7 during the machining process and improving the reliability of the machining device.
[0033] Furthermore, a bushing boss 26 can be provided on each of the aforementioned positioning planes 21, the length of which is adapted to the length of the copper sliding tile blank 1. Therefore, a groove 27 is formed between the bushing boss 26 and the first frustum 22. The aforementioned bolt holes 25 are located within the groove 27, allowing the wedge-shaped pressure block 4 to slide down into it, thereby increasing the stroke of the wedge-shaped pressure block 4 and facilitating its pressing against the copper sliding tile blank 1.
[0034] like Figure 11As shown, the axle 2 is rotated 180° on a lathe, and another copper sliding tile blank 1 and two wedge-shaped pressure blocks 4 are installed. The arc surfaces of the copper sliding tile boss 13 and mating surface 14 are machined using a machining tool 7. The machining tool 7 can be a 90° offset tool. After checking the dimensions of each part of the machined copper sliding tile and confirming that they are correct, the copper sliding tiles in the same group are disassembled, numbered, and stored.
[0035] It should be noted that, as Figure 5 As shown, the distance between the two axle bosses 26 that contact the bottom surface of the copper sliding tile blank 1 is determined based on the target radius of the arc surface of the copper sliding tile boss 13 and the mating surface 14. Taking the arc surface of the boss 13 as an example, the distance between the two axle bosses 26 must ensure that the arc surfaces of the two machined bosses 13 are coaxial, and that this axis coincides with the axis of the axle 2. In this way, the arc surfaces of the two machined copper sliding tiles are identical, achieving the purpose of paired processing.
[0036] The processing device for the universal joint copper sliding bearing of the ring rolling mill of this utility model adopts a clamping and lifting method to firmly install the axle 2 on the lathe, which improves the processing stability.
[0037] Furthermore, the positioning mandrel 3 can simultaneously and accurately position two copper sliding tile blanks 1, ensuring that the two copper sliding tile blanks 1 are machined to have the same arc surface. The wedge-shaped pressure block 4 can press the copper sliding tile blank 1 tightly onto the positioning plane 21, preventing the copper sliding tile blank 1 from loosening during processing and improving the reliability of the processing device.
[0038] By limiting the stroke of the wedge-shaped pressure block 4 through the first truncated cone 22 and preventing the wedge-shaped pressure block 4 from moving along the axis of the tire shaft 2, the processing position of the copper sliding tile blank 1 is guaranteed.
[0039] In addition, by setting a tire axle boss 26 on the positioning plane 21, a groove 27 is formed between it and the first truncated cone 22, thereby increasing the stroke of the wedge-shaped pressure block 4, which is beneficial for the wedge-shaped pressure block 4 to press the copper sliding tile blank 1.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
