Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a device for machining the thickness of non-magnetic thrust rings. Background Technology

[0002] As a key component for axial positioning of the engine crankshaft, the thrust ring's main function is to precisely control the crankshaft's axial displacement, ensuring engine operational stability. Currently, the industry commonly employs a segmented manufacturing process, using multiple size options to accommodate different assembly clearance requirements. However, this traditional manufacturing method has significant limitations: firstly, overly detailed segmentation leads to a complex procurement of various items, significantly increasing the difficulty of warehouse management; secondly, during actual assembly, due to the cumulative effect of component machining errors, situations often arise where the appropriate segment cannot be matched, necessitating individual component modification to meet assembly requirements.

[0003] Furthermore, thrust rings are generally made of tin bronze, a material whose properties prevent them from being clamped and fixed using conventional magnetic chucks, significantly complicating subsequent machining. In existing processing techniques, manufacturers typically use surface grinders for finishing, where parts are glued to the machine tool's flat surface. This method has several drawbacks: firstly, after machining, the parts need to be disassembled by tapping with a wooden stick, easily causing damage to the outer diameter of the parts and resulting in excessive parallelism of the machined surfaces; secondly, the glued fixing method is inefficient, and during high-speed grinding, there is a safety hazard of parts flying due to adhesive failure. These process defects not only affect product quality stability but also restrict the improvement of production efficiency, necessitating the development of new machining tooling to solve these problems. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention provides a device for processing the thickness of non-magnetic thrust rings, which can realize the processing and fitting of thrust ring thickness, thereby improving processing efficiency.

[0005] The apparatus for processing the thickness of a non-magnetic thrust ring according to the first aspect of the present invention comprises:

[0006] A positioning body, one end of which is provided with a first conical surface and a mounting hole;

[0007] Tighten the nut, the inner sidewall of which is provided with a second conical surface that mates with the first conical surface of the positioning body;

[0008] A positioning element, which mates with the mounting hole, is used to achieve circumferential positioning of the entire thrust ring;

[0009] The positioning body defines a receiving cavity for installing the thrust ring. After the nut is installed and tightened, when the thrust ring is placed in the receiving cavity, the positioning element is inserted into the mounting hole to achieve the positioning and fixation of the thrust ring.

[0010] According to this utility model, the device for machining the thickness of a non-magnetic thrust ring can achieve the positioning and fixing of the thrust ring through the cooperation of the positioning body, the tightening nut, and the positioning component. Simultaneously, after machining, the positioning component and the tightening nut can be removed to disassemble the thrust ring, making the disassembly process simple. The assembly and disassembly process is simple and efficient due to the cooperation of each component; and the flat end of the positioning body allows for precise thickness correction of the thrust ring inserted at that end, while eliminating the safety hazard of parts splashing during high-speed grinding, ensuring high safety.

[0011] In some embodiments of this utility model, the first conical surface of the positioning body is provided with an elastic pressing opening groove. When the nut is screwed in, the first conical surface undergoes elastic deformation and presses against the upper and lower thrust rings to achieve positioning and fixation.

[0012] In some embodiments of this utility model, the number of opening slots is six, and all the opening slots are evenly distributed along the circumferential direction of the positioning body.

[0013] In some embodiments of this utility model, the positioning element is a bolt, the bolt has an external thread, and the mounting hole has an internal thread that mates with the external thread.

[0014] In some embodiments of this utility model, a gasket is also included, which is installed between the end of the positioning body and the thrust ring, and the gasket has a through hole that matches the mounting hole. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is for reference. Figures 1 to 4 The device for processing the thickness of a non-magnetic thrust ring according to an embodiment of the present invention includes a positioning body 1, a tightening nut 2, and a positioning element 3. One end of the positioning body 1 has a first conical surface 11 and a mounting hole 12. The inner wall of the tightening nut 2 has a second conical surface that mates with the first conical surface 11 of the positioning body 1. The positioning element 3 mates with the mounting hole 12 to achieve circumferential positioning of the entire thrust ring 4. The positioning body 1 defines a receiving cavity for mounting the thrust ring 4. After the tightening nut 2 is installed, when the thrust ring 4 is placed in the receiving cavity, the positioning element 3 is inserted into the mounting hole 12, thereby achieving positioning and fixing of the thrust ring 4.

[0026] For example, one end of the positioning body 1 defines a receiving cavity for mounting the thrust ring 4, the space of which can change as the tightening nut 2 is installed. The positioning body 1 and the tightening nut 2 together achieve radial positioning of the thrust ring 4. Specifically: first, the thrust ring 4 is installed in the receiving cavity, and the tightening nut 2 is mounted on the positioning body 1 from the receiving cavity side, generating a radial compressive force from the outside to the inside on the thrust ring 4 to achieve radial clamping. Then, the positioning element 3 is inserted into the mounting hole 12 to achieve axial positioning of the thrust ring 4. There are at least two mounting holes 12, and the positional relationship between the two mounting holes 12 matches the connecting hole on the thrust ring 4 to achieve positioning and fixation of the thrust ring 4. The end of the positioning body 1 away from the receiving cavity is provided with a mounting post to facilitate the installation of the entire processing device. Of course, there can be more mounting holes 12, as long as the positional relationship between two adjacent mounting holes 12 matches the positional relationship between the two connecting holes in the thrust ring 4.

[0027] It should be noted that, as Figure 1 and Figure 2As shown, the thrust ring 4 mentioned in this utility model may include an upper thrust ring 41 and a lower thrust ring 42. Both the upper thrust ring 41 and the lower thrust ring 42 are fan-shaped structures, forming a circular structure together. The central angle of the upper thrust ring 41 is larger than that of the lower thrust ring 42, and the ends of the upper thrust ring 41 and the lower thrust ring 42 are formed with connecting holes for connecting and positioning the upper thrust ring 41 and the lower thrust ring 42. Specifically, the ends of both the upper thrust ring 41 and the lower thrust ring 42 are provided with semi-circular notches. When the thrust ring 4 is installed into the receiving cavity, a portion of it is ensured to extend beyond the receiving cavity, thus enabling the correction of the thickness of the thrust ring 4.

[0028] Understandably, during use, the entire processing device can first be mounted on the operating table, and the tightening nut 2 can be initially mounted on the positioning body 1, with the tightening nut 2 in a loose state. Then, the upper thrust ring 41 and lower thrust ring 42 are installed in the receiving cavity, aligning the connecting hole of the thrust ring 4 with the mounting hole 12. Next, the positioning piece 3 is inserted through the connecting hole into the mounting hole 12, achieving initial axial positioning of the thrust ring 42. Then, the tightening nut 2 is tightened, reducing the size of the receiving cavity to achieve radial positioning of the thrust ring 42 from the external circumferential direction. Finally, the fixing positioning piece 3 is tightened to achieve axial positioning of the thrust ring 4. Of course, the order of axial and radial positioning can be freely adjusted according to the needs of installation, and will not be elaborated here. After the thrust ring 4 is positioned and fixed, the entire processing device can be mounted on the operating table to achieve the processing of the thickness of the thrust ring 4.

[0029] According to the device for machining the thickness of a non-magnetic thrust ring of this utility model, the thrust ring 4 can be positioned and fixed by the cooperation of the positioning body 1, the tightening nut 2, and the positioning element 3. Simultaneously, after machining, the positioning element 3 and the tightening nut 2 can be removed to disassemble the thrust ring 4, making the disassembly process simple. Through the cooperation of each component, the assembly and disassembly process is simple and efficient; and the flat end of the positioning body 1 allows for precise thickness correction of the thrust ring 4 inserted at that end, and there is no safety hazard of parts splashing during high-speed grinding, ensuring high safety.

[0030] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 As shown, the first conical surface 11 of the positioning body 1 is provided with an elastic pressing opening groove 13. For example, there are multiple opening grooves 13, which are evenly distributed along the circumference of the positioning body 1. Among them, six opening grooves 13 are optimal. When the nut 2 is screwed in, the first conical surface 11 undergoes elastic deformation and presses against the upper thrust ring 41 and the lower thrust ring 42, thereby achieving the positioning and fixation of the entire thrust ring 4.

[0031] Understandably, the opening slot 13 allows the end of the positioning body 1 to deform under external force, thereby adjusting the internal cavity size of the entire positioning body 1 and achieving circumferential positioning and clamping of the internal thrust ring 4. The multiple opening slots 13 are evenly distributed along the circumferential direction, ensuring uniform force distribution on the thrust ring 4, improving the stability of clamping and positioning, and preventing parts from splashing during high-speed grinding.

[0032] In some embodiments of this utility model, the positioning element 3 is a bolt with external threads, and the mounting hole 12 has internal threads that mate with the external threads. For example, the positioning element 3 has a T-shaped structure, including a threaded rod and a limiting plate. The threaded rod is vertically positioned at the center of the limiting plate, and the size of the limiting plate matches the size of the connecting hole. The thrust ring 4 can be pressed against the receiving cavity of the positioning body 1 through the connecting hole. When the positioning element 3 is screwed into the mounting hole 12, the end of the positioning element 3 away from the positioning body 1 (i.e., the end of the limiting plate away from the positioning body 1) does not exceed the outermost end of the thrust ring 4, thereby ensuring that the positioning element 3 will not affect the processing of the thrust ring 4.

[0033] Understandably, the positioning element 3 can be installed in the mounting hole 12 through the engagement of the external and internal threads. In other words, the thrust ring 4 and the positioning body 1 are connected by bolts, which not only facilitates assembly and disassembly but also improves the stability of the connection, ensuring that parts will not splash during high-speed grinding, resulting in a high safety factor.

[0034] Considering that different thrust rings 4 require different thicknesses to be processed, in order to achieve different thicknesses, in some embodiments of this utility model, a gasket may also be included. The gasket is installed between the end of the positioning body 1 and the thrust ring 4, and a through hole is provided on the gasket to cooperate with the mounting hole 12.

[0035] Understandably, the addition of shims can improve the stability and tightness of the connection between the thrust ring 4 and the positioning body 1, preventing slippage and unstable connection between the two. Moreover, the shims can be available in various thicknesses. By replacing shims of different specifications, the thickness of the portion of the thrust ring 4 extending beyond the positioning body 1 can vary, thereby enabling grinding processes of different thicknesses.

[0036] In summary, the positioning and fixing of the thrust ring can be achieved through the cooperation of the positioning body, tightening nut, and positioning component. The assembly and disassembly process is simple and efficient. Furthermore, the cooperation of each component ensures reliable installation, preventing parts from splashing during high-speed grinding and improving safety. Standard parts can be set for the positioning body, tightening nut, and positioning component according to the dimensions of the thrust ring to be processed, which can improve the quality stability of the processed thrust ring. The assembly and disassembly process is simple and convenient, improving the processing efficiency of the thrust ring.
