Description

Technical Field

[0001] The present application belongs to the technical field of bearing processing equipment, and in particular relates to a method and equipment for processing a tilting pad thrust bearing pad. Background Art

[0002] Self-balancing tilting pad thrust bearings with balancing weights are widely used in high-speed rotating equipment such as pumps, steam turbines, fans, and compressors that experience heavy axial loads. The rotors of these high-speed rotating equipment are generally mounted horizontally. Conventional self-balancing tilting pad thrust bearings do not fully restrict the thrust pads; the bearing housings only have circumferential notches to limit the circumferential movement of the thrust pads. Due to the high processing requirements for these tilting pads, traditional surface machining methods such as milling and grinding of tilting pad thrust bearings suffer from problems such as a small contact area between the tool and the workpiece (a point contact process), large machining allowances, severe tool wear, low machining efficiency, and low cutting accuracy, necessitating improvements. Summary of the Invention

[0003] The purpose of this application is to provide a tilting pad thrust bearing pad processing method and equipment, which can solve the above problems.

[0004] The purpose of this application is to provide a method for machining a tilting pad thrust bearing pad, comprising the following steps:

[0005] S1. Material preparation: prepare round forgings as processing blanks;

[0006] S2. Preliminary processing: turning the inner hole of the forging, rough machining the outer circle and end face, casting the bearing alloy, and finishing the inner hole and outer circle to obtain the workpiece;

[0007] S3. Marking: Mark the center line, contour line and center line of the positioning pin hole on the end face of the workpiece;

[0008] S4, Wire Cutting and Finish Turning: Use wire cutting equipment to divide the workpiece into four arc-shaped parts, finish turning them on a CNC lathe, and then wire cut the inclined surface and radial surface;

[0009] S5, milling: machining center processes the back arc of the arc body to make it meet the requirements of the bearing pad;

[0010] S6. Grinding: Grind and remove burrs from the bearing pads.

[0011] By adopting the above-mentioned method for processing tilting pad thrust bearing blocks, the processing accuracy is significantly improved by introducing wire cutting technology, and the problems of severe tool wear and low processing efficiency in traditional processing methods are effectively avoided. At the same time, this method also ensures the stability and reliability of the processing process, providing a strong guarantee for the high-quality production of tilting pad thrust bearing blocks.

[0012] Furthermore, the wire cutting equipment used in step S4 is an electric spark wire cutting equipment, and the electric spark wire cutting equipment includes:

[0013] frame;

[0014] A routing mechanism, including a routing assembly and a metal wire;

[0015] The workbench is arranged on the frame, and a sliding seat and a placement rack are provided on the surface of the workpiece;

[0016] The metal wire passes through the placement frame and is slidably connected to the placement frame.

[0017] The frame serves as the supporting structure for the entire machine, ensuring stability and machining accuracy. The wire routing mechanism includes a routing assembly and the cutting wire. The routing assembly drives the wire along a specific path and speed to achieve the cutting function. The workbench is mounted on the frame, its surface designed with a sliding seat and a dedicated workpiece placement rack. This not only facilitates workpiece positioning and adjustment but also increases machining flexibility. The wire runs through the placement rack and is connected to it through a sliding connection, allowing it to pass smoothly through the rack during the cutting process while maintaining stable contact with the workpiece, thus ensuring cutting accuracy and efficiency.

[0018] Further: the routing component includes:

[0019] A support seat, the top of which is rotatably provided with a take-up wheel;

[0020] The support column has a lower wiring rack at the bottom of its side wall and an upper wiring rack slidably arranged thereon;

[0021] Fixed pulleys are provided at both ends of the upper and lower cable trays;

[0022] The metal wire is slidably connected to the take-up wheel and the fixed pulley.

[0023] The support base serves as the foundation of the wire routing assembly. A rotating take-up reel is mounted on top of the support base, which winds and feeds the wire for continuous feeding during the cutting process. The support column supports the upper and lower wire routing frames, which together form the track for the wire. The upper wire routing frame slides on the support column, while the lower wire routing frame remains stationary. This allows the upper frame to be fine-tuned according to processing requirements, ensuring optimal wire cutting angle and tension. Fixed pulleys are installed at both ends of the upper and lower wire routing frames to guide the wire along the predetermined path, ensuring stable and accurate cutting. One end of the wire is connected to the take-up reel, while the other end is slidably connected to the fixed pulley. During the cutting process, the rotation of the take-up reel drives the wire continuously, while the fixed pulley ensures smooth wire movement throughout the routing system.

[0024] Furthermore, a moving mechanism is provided on the support column, and the upper wiring rack is provided on the moving mechanism, and the moving mechanism includes:

[0025] There are two guide grooves;

[0026] The slider has two plugs that fit into the guide groove at one end and is connected to the upper wiring rack at the other end;

[0027] A driver is provided on the top of the support column and is used to drive the slider to move, and its output shaft is provided with a screw connected to the slider;

[0028] Among them, a stabilizing structure is provided between the insert block and the guide groove, which is used to adjust the moving speed of the upper wiring mechanism to make its movement more stable, thereby making the cutting more stable.

[0029] Two guide grooves are provided on the support column as guide paths for the movement of the slider, ensuring that the slider can move smoothly in the predetermined direction. One end of the slider is equipped with two plugs that are compatible with the guide grooves to provide stable support for the movement of the slider, and the other end is connected to the upper wiring, thereby realizing the drive and control of the entire wiring rack. The driver is installed on the top of the support column, and a screw is connected to its output shaft, which cooperates with the slider. When the driver is started, the slider is driven by the screw to move along the guide groove, thereby driving the upper wiring rack to make corresponding adjustments. At the same time, in order to further improve the stability of the moving mechanism, a stabilizing structure is set between the plug and the guide groove, which can effectively adjust the moving speed of the upper wiring mechanism, so that it can maintain a smooth and uniform movement under any circumstances, thereby ensuring the stability and accuracy of the cutting process.

[0030] Furthermore, the stable structure includes:

[0031] A guide groove is provided on the support column and is located between the two guide grooves;

[0032] The resistance assembly is composed of a piston shaft and a sleeve, wherein the end of the piston shaft away from the sleeve is fastened to one end of the guide groove, and the sleeve can slide in the guide groove and is connected to the slider;

[0033] A first elastic element is disposed in the guide groove and connected to an end of the sleeve away from the piston shaft;

[0034] A guide shock-absorbing assembly is disposed in the guide groove and connected to the slider;

[0035] There are two guide shock-absorbing components, which are symmetrically arranged on both sides of the resistance assembly.

[0036] The guide groove is provided on the support column and is located between the two guide grooves, providing a precise path and support for the movement of the resistance assembly. The resistance assembly consists of a piston shaft and a sleeve. One end of the piston shaft is firmly fixed to one end of the guide groove, while the sleeve can slide smoothly in the guide groove, and the sleeve is connected to the slider, so that when the slider moves, the sleeve will move with it. At the same time, a first elastic element is provided in the guide groove, which is connected to the end of the sleeve away from the piston shaft. The elasticity of this elastic element can further adjust the moving speed of the slider (i.e., the upper wiring rack) and increase its stability. In addition, in order to more effectively absorb vibrations during movement, two guide shock-absorbing assemblies are also provided in the guide groove. They are symmetrically distributed on both sides of the resistance assembly, which can significantly reduce the shaking and vibration of the slider during movement, thereby ensuring the stability and accuracy of the cutting process.

[0037] As the slider moves, the sleeve glides smoothly within the guide groove. Simultaneously, the movement of the piston shaft relative to the sleeve produces a damping effect, slowing the slider's movement and ensuring greater stability. The elasticity of the first elastic element further adjusts this movement speed to best suit processing requirements. Assisted by the guide damping assembly, the entire moving mechanism effectively absorbs and reduces vibration, ensuring stable and precise cutting.

[0038] Furthermore, the guide shock absorbing assembly includes:

[0039] A lateral guide groove is provided inside the guide groove;

[0040] A sliding element 1 is disposed in the lateral guide groove and connected to the slider, and is capable of sliding in the lateral guide groove;

[0041] The second sliding element is disposed in the lateral guide groove and is connected to the first sliding element by a hinge;

[0042] a second elastic element, one end of which is connected to the lateral guide groove and the other end of which is connected to the second sliding element;

[0043] The second elastic element is located in the lateral guide groove, and one end of the second elastic element away from the sliding element is fixedly connected to the lateral guide groove.

[0044] The lateral guide groove is arranged inside the guide groove to provide a path and support for the movement of the sliding element. The moving element 1 is arranged in the lateral guide groove and is connected to the slider. As the slider moves, the sliding element 1 will also slide smoothly in the lateral guide groove, thereby playing a guiding and supporting role. The sliding element 2 is also arranged in the lateral guide groove, but unlike the sliding element 1, it is connected to the sliding element 1 by a hinge. This allows the sliding element 2 to move in the lateral guide groove while turning within a certain range, thereby better adapting to the path changes of the lateral guide groove. One end of the second elastic element is connected to the lateral guide groove, and the other end is connected to the sliding element 2. When the slider moves, the second elastic element expands and contracts under the action of the sliding element 2, thereby effectively absorbing and mitigating the impact force and further reducing vibration.

[0045] Furthermore, the lateral guide groove includes a straight guide portion and a bending limiting portion, the straight guide portion is arranged in a straight line shape, and the bending limiting portion has an arc-shaped feature, and the sliding element 2 matches the bending limiting portion and can slide smoothly into the bending limiting portion.

[0046] The straight-line guide portion is in a straight line shape, providing a stable straight-line movement path for the sliding element. When the slider moves, sliding element one will move smoothly in a straight line along this portion. The bending limiting portion is different from the straight-line guide portion and has an arc-shaped feature. Sliding element two is designed to match this portion and can slide smoothly into the bending limiting portion. When the sliding element moves to this area, its moving direction will change and will be subject to certain restrictions, so that it cannot continue to move in a straight line. When the sliding element enters the bending limiting portion, the second elastic element will be further stretched. In this process, the force originally acting in the straight line will be dispersed in the bending direction, thereby effectively reducing the impact force and improving the stability and adjustment effect of the equipment.

[0047] In addition, the design of the bend-limiting portion allows the sliding element to gradually slow down during movement, avoiding the severe impact and vibration caused by sudden changes in direction. This smooth transition not only improves the operating efficiency of the equipment, but also further extends its service life.

[0048] Furthermore, limiting sliding grooves are provided on both sides of the guide groove, and limiting protrusions adapted to the limiting sliding grooves are provided on both sides of the sleeve.

[0049] Limiting protrusions that match the limiting grooves are set on both sides of the sleeve. The limiting protrusions are embedded in the limiting grooves, thereby ensuring that the sleeve will not deviate from the predetermined path during movement, avoiding errors and instability caused by offset. At the same time, it also greatly reduces the friction and wear caused by offset, and extends the service life of the equipment.

[0050] The beneficial effects of this application are:

[0051] 1. By introducing wire cutting technology, the processing accuracy is significantly improved, effectively avoiding the problems of severe tool wear and low processing efficiency in traditional processing methods. At the same time, this method also ensures the stability and reliability of the processing process, providing a strong guarantee for the high-quality production of tilting pad thrust bearing blocks;

[0052] 2. When the slider moves, the sleeve will slide smoothly in the guide groove. At the same time, the movement of the piston shaft relative to the sleeve will produce a certain damping effect. This damping effect can slow down the movement speed of the slider and make it more stable.

[0053] 3. By relying on the elasticity of the first elastic element, the moving speed of the slider can be further adjusted to make it more in line with processing requirements. With the assistance of the guide shock-absorbing component, the entire moving mechanism can more effectively absorb and reduce vibration, thereby ensuring the stability and accuracy of the cutting process.

At the same time, this method also ensures the stability and reliability of the processing process, providing a strong guarantee for the high-quality production of tilting pad thrust bearing blocks.

[0073] Example 2:

[0074] An embodiment of the present application provides a processing device for a tilting pad thrust bearing pad processing method. In addition to the above-mentioned technical features, the processing equipment of the embodiment of the present application also includes the following technical features.

[0075] like Figure 1 As shown, the wire cutting equipment used in step S4 is an electric spark wire cutting equipment, and the electric spark wire cutting equipment includes:

[0076] Rack 100;

[0077] The wiring mechanism 200 includes a wiring assembly 210 and a metal wire 220;

[0078] The workbench 300 is provided on the frame 100, and a sliding seat 310 and a placement rack 320 are provided on the surface thereof, and the workpiece is placed on the placement rack 320;

[0079] The metal wire 220 passes through the placement rack 320 and is slidably connected to the placement rack 320 .

[0080] In an embodiment of the present application, the frame 100 serves as the supporting structure of the entire device, ensuring the stability and processing accuracy of the device. The routing mechanism 200 includes a routing assembly 210 and a metal wire 220 for cutting. The routing assembly 210 is responsible for driving the metal wire 220 to move along a certain path and speed to achieve the cutting function. The workbench 300 is installed on the frame 100, and its surface is designed with a sliding seat 310 and a placement rack 320 specifically for placing workpieces, which not only facilitates the positioning and adjustment of the workpiece, but also improves the flexibility of the processing process. The metal wire 220 passes through the placement rack 320 and is slidably connected to the placement rack 320, so that the metal wire 220 can pass smoothly through the placement rack 320 during the cutting process while maintaining stable contact with the workpiece, thereby ensuring the accuracy and efficiency of the cutting.

[0081] Furthermore, the wiring assembly 210 includes:

[0082] A support base 211, a take-up wheel 212 is rotatably provided on the top thereof;

[0083] The support column 213 has a lower wiring rack 214 at the bottom of its side wall, and an upper wiring rack 215 is slidably provided;

[0084] Fixed pulleys 216 are provided at both ends of the upper wiring rack 215 and the lower wiring rack 214;

[0085] The metal wire 220 is slidably connected to the take-up wheel 212 and the fixed pulley 216 .

[0086] The support base 211 serves as the base of the wire assembly 210. A rotating take-up reel 212 is mounted on top of the support base 211, which winds and feeds the wire 220 for continuous feeding during the cutting process. The support column 213 supports the upper and lower wire frames 215 and 214, which together form a track for the wire 220 to move along. The upper wire frame 215 slides on the support column 213, while the lower wire frame 214 remains stationary. This allows the upper wire frame 215 to be fine-tuned according to processing requirements, ensuring that the wire 220 maintains the optimal cutting angle and tension. Fixed pulleys 216 are installed at both ends of the upper and lower wire frames 215 and 214, guiding the wire 220 along a predetermined path and ensuring stability and accuracy during the cutting process. One end of the wire 220 is connected to the take-up reel 212, while the other end is slidably connected to the fixed pulley 216. During the cutting process, the rotation of the take-up wheel 212 drives the metal wire 220 to move continuously, and the fixed pulley 216 ensures that the metal wire 220 can smoothly pass through the entire routing system.

[0087] Example 3:

[0088] An embodiment of the present application provides a processing device for a tilting pad thrust bearing pad processing method. In addition to the above-mentioned technical features, the processing equipment of the embodiment of the present application also includes the following technical features.

[0089] like Figures 1 to 3 As shown, a moving mechanism 400 is provided on the support column 213, and the upper wiring rack 215 is provided on the moving mechanism 400. The moving mechanism 400 includes:

[0090] There are two guide grooves 410;

[0091] The slider 420 has two plugs 421 on one end that fit into the guide slot 410 and the other end that is connected to the upper wiring rack 215;

[0092] The driver 430 is provided on the top of the support column 213 and is used to drive the slider 420 to move. The output shaft of the driver 430 is provided with a screw connected to the slider 420;

[0093] A stabilizing structure 500 is provided between the inserting block 421 and the guide groove 410 for adjusting the moving speed of the upper wiring mechanism 200 to make its movement more stable, thereby making the cutting more stable.

[0094] In an embodiment of the present application, two guide grooves 410 are provided on the support column 213 as guide paths for the movement of the slider 420, ensuring that the slider 420 can move smoothly along a predetermined direction. One end of the slider 420 is equipped with two plugs 421 adapted to the guide grooves 410, providing stable support for the movement of the slider 420, and the other end is connected to the upper wiring, thereby realizing the drive and control of the entire wiring rack. Driver 430 Driver 430 is installed on the top of the support column 213, and a screw is connected to its output shaft, which cooperates with the slider 420. When the driver 430 is started, the slider 420 is driven by the screw to move along the guide groove 410, thereby driving the upper wiring rack 215 to make corresponding adjustments. At the same time, in order to further improve the stability of the moving mechanism 400, a stabilizing structure 500 is set between the plug block 421 and the guide groove 410, which can effectively adjust the moving speed of the upper wiring mechanism 200 so that it can maintain smooth and uniform movement under any circumstances, thereby ensuring the stability and accuracy of the cutting process.

[0095] Example 4:

[0096] An embodiment of the present application provides a processing device for a tilting pad thrust bearing pad processing method. In addition to the above-mentioned technical features, the processing equipment of the embodiment of the present application also includes the following technical features.

[0097] like Figures 2 to 5 As shown, the stabilizing structure 500 includes:

[0098] A guide groove 510 is provided on the support column 213 and is located between the two guide grooves 410;

[0099] The resistance assembly 520 is composed of a piston shaft 521 and a sleeve 522. The end of the piston shaft 521 away from the sleeve 522 is fastened to one end of the guide groove 510. The sleeve 522 can slide in the guide groove 410 and is connected to the slider 420.

[0100] The first elastic element 530 is disposed in the guide groove 410 and connected to the end of the sleeve 522 away from the piston shaft 521;

[0101] The guide shock absorbing assembly 600 is disposed in the guide groove 410 and connected to the slider 420;

[0102] There are two guide shock absorbing components 600 , which are symmetrically arranged on both sides of the resistance assembly 520 .

[0103] In the embodiment of the present application, the guide groove 510 is provided on the support column 213 and is located between the two guide grooves 410, providing a precise path and support for the movement of the resistance assembly 520. The resistance assembly 520 is composed of a piston shaft 521 and a sleeve 522. One end of the piston shaft 521 is firmly fixed to one end of the guide groove 510, while the sleeve 522 can slide smoothly in the guide groove 510, and the sleeve 522 is connected to the slider 420, so that when the slider 420 moves, the sleeve 522 will also move. At the same time, a first elastic element 530 is provided in the guide groove 410, which is connected to the end of the sleeve 522 away from the piston shaft 521. The elasticity of this elastic element can further adjust the moving speed of the slider 420 (i.e., the upper wiring rack 215) and increase its stability. In addition, in order to more effectively absorb vibrations during movement, two guide shock-absorbing components 600 are also arranged in the guide groove 410. They are symmetrically distributed on both sides of the resistance assembly 520, which can significantly reduce the shaking and vibration of the slider 420 during movement, thereby ensuring the stability and accuracy of the cutting process.

[0104] As the slider 420 moves, the sleeve 522 slides smoothly within the guide groove 510. Simultaneously, the movement of the piston shaft 521 relative to the sleeve 522 produces a damping effect, which slows down the movement of the slider 420 and stabilizes it. The elasticity of the first elastic element 530 further adjusts this movement speed to better meet processing requirements. With the assistance of the guide damping assembly 600, the entire moving mechanism 400 can more effectively absorb and reduce vibration, thereby ensuring stability and precision during the cutting process.

[0105] Example 5:

[0106] An embodiment of the present application provides a processing device for a tilting pad thrust bearing pad processing method. In addition to the above-mentioned technical features, the processing equipment of the embodiment of the present application also includes the following technical features.

[0107] like Figures 2 to 5 As shown, the guide shock absorbing assembly 600 includes:

[0108] A lateral guide groove 610 is provided inside the guide groove;

[0109] A sliding element 620 is disposed in the lateral guide groove 610 and connected to the slider 420 and is capable of sliding in the lateral guide groove 610;

[0110] The second sliding element 630 is disposed in the lateral guide groove 610 and is connected to the first sliding element 620 by a hinge;

[0111] A second elastic element 640, one end of which is connected to the lateral guide groove 610, and the other end is connected to the second sliding element 630;

[0112] The second elastic element 640 is located in the lateral guide groove 610 , and one end of the second elastic element away from the sliding element is fixedly connected to the lateral guide groove 610 .

[0113] In this embodiment of the present application, a lateral guide groove 610 is disposed within the guide groove to provide a path and support for the movement of the sliding element. A first moving element is disposed within the lateral guide groove 610 and is connected to the slider 420. As the slider 420 moves, the first sliding element 620 also slides smoothly within the lateral guide groove 610, thereby providing guidance and support. A second sliding element 630 is also disposed within the lateral guide groove 610, but unlike the first sliding element 620, it is connected to the first sliding element 620 via a hinged connection. This allows the second sliding element 630 to steer within a certain range while moving within the lateral guide groove 610, thereby better adapting to changes in the path of the lateral guide groove 610. A second elastic element 640 has one end connected to the lateral guide groove 610 and the other end connected to the second sliding element 630. When the slider 420 moves, the second elastic element 640 expands and contracts under the action of the second sliding element 630, effectively absorbing and mitigating the impact force, further reducing vibration.

[0114] Furthermore, limiting sliding grooves 540 are provided on both sides of the guide groove 510 , and limiting protrusions 541 adapted to the limiting sliding grooves 540 are provided on both sides of the sleeve 522 .

[0115] In some embodiments of the present application, limiting protrusions 541 adapted to the limiting grooves 540 are provided on both sides of the sleeve 522, and the limiting protrusions 541 are embedded in the limiting grooves 540, thereby ensuring that the sleeve 522 will not deviate from the predetermined path during movement, avoiding errors and instabilities caused by offset, and at the same time, greatly reducing the friction and wear caused by offset, thereby extending the service life of the equipment.

[0116] Example 6:

[0117] An embodiment of the present application provides a processing device for a tilting pad thrust bearing pad processing method. In addition to the above-mentioned technical features, the processing equipment of the embodiment of the present application also includes the following technical features.

[0118] like Figures 2 to 5 As shown, the lateral guide groove 610 includes a straight guide portion 611 and a curved limiting portion 612. The straight guide portion 611 is arranged in a straight line shape, while the curved limiting portion 612 has an arc-shaped feature, and the sliding element 2 630 matches the curved limiting portion 612 and can slide smoothly into the curved limiting portion 612.

[0119] In an embodiment of the present application, the row guide portion 611 is in a straight line shape, providing a stable straight line movement path for the sliding element. When the slider 420 moves, the sliding element 1 620 will move smoothly in a straight line along this part. The curved limiting portion 612 is different from the straight guide portion 611 and has an arc-shaped feature. The sliding element 2 630 is designed to match this part and can slide smoothly into the curved limiting portion 612. When the sliding element moves to this area, its moving direction will change and be subject to certain restrictions, so that it cannot continue to move in a straight line. When the sliding element enters the curved limiting portion 612, the second elastic element 640 will be further stretched. In this process, the force originally acting in the straight line will be dispersed in the curved direction, thereby effectively reducing the impact force and improving the stability and adjustment effect of the device.

[0120] In addition, the design of the bending limiting portion 612 also enables the sliding element to gradually slow down during movement, avoiding severe impact and vibration caused by sudden changes in direction. This smooth transition not only improves the operating efficiency of the equipment, but also further extends its service life.
