Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a high-temperature alloy substrate grinding equipment with a NiCrAlY coating. Background Technology

[0002] NiCrAlY coating is a protective coating widely used on the surface of high-temperature alloy substrates. Its core function is to improve the oxidation and hot corrosion resistance of the substrate material in high-temperature environments, thereby extending the service life of the material. It can still maintain high strength and plasticity at high temperatures. Elements such as chromium and aluminum in the alloy form a dense oxide film at high temperatures, preventing the intrusion of oxygen and corrosive media. It has good structural stability at high temperatures and is not prone to phase transformation or performance degradation. Nickel-based high-temperature alloys are the most widely used type of high-temperature alloys and are often used to manufacture hot-end components such as aero engines and gas turbines.

[0003] The existing NiCrAlY coated high-temperature alloy substrates require grinding during the manufacturing process of parts, necessitating the use of appropriate grinding equipment. Currently, the grinding equipment used for grinding NiCrAlY coated high-temperature alloy substrates consists of a clamping component and a grinding assembly. The clamping component holds the workpiece, and then the grinding assembly grinds it. The grinding assembly mainly consists of a motor and a grinding wheel. However, during the actual grinding process, coolant needs to be sprayed onto the surface of the grinding wheel for cooling. But the coolant requires a separate power mechanism to pump it out, which is inconvenient to achieve by using the power of the grinding wheel's rotation. Therefore, a new technical solution needs to be designed to address this issue. Summary of the Invention

[0004] The purpose of this invention is to provide a high-temperature alloy substrate grinding device with a NiCrAlY coating, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for a high-temperature alloy substrate with a NiCrAlY coating, comprising a base, wherein a clamping assembly is fixedly installed on one side of the top of the base; A drive assembly is installed on the other side of the top of the base. A support plate is installed on the drive assembly. A retainer is fixedly installed on one side wall of the support plate. A grinding wheel is rotatably installed inside the retainer. A first hollow shaft is fixedly connected to one side wall of the grinding wheel. The first hollow shaft movably passes through the retainer and is connected to a power assembly. A second hollow shaft is fixedly connected to the other end of the grinding wheel. The second hollow shaft movably passes through the retainer and is connected to a suction assembly. A fixing frame is fixedly installed on the top of the support plate. A nozzle is fixedly connected to the bottom of the outer end of the fixing frame. A conduit is connected to the outer end of the first hollow shaft through a rotary joint. The outer end of the conduit is connected to the nozzle.

[0006] By adopting the above technical solution, the workpiece to be ground is first clamped and fixed using a clamping assembly. Then, a drive assembly moves a support plate, bringing the grinding wheel close to and against the workpiece. A power assembly drives the first hollow shaft to rotate, thereby rotating the grinding wheel. The rotating grinding wheel grinds the workpiece. During grinding, the second hollow shaft rotates, driving a suction assembly to draw coolant into the second hollow shaft. The coolant then passes through the grinding wheel and into the inner cavity of the first hollow shaft, then through a guide tube into the nozzle cavity. The coolant is then guided to the surface of the grinding wheel, thus rinsing and cooling the grinding wheel. This also helps reduce debris adhesion to the grinding wheel surface. The coolant passes through the inner cavity of the grinding wheel, cooling it from the inside. Combined with the rinsing and cooling of the outer wall of the grinding wheel, this improves the cooling effect and prevents heat buildup inside the grinding wheel, which could lead to accelerated wear and tear, thus extending the grinding wheel's service life.

[0007] In a preferred embodiment of this utility model, the suction assembly includes a fixed shell, which is fixed to one side wall of the retainer. A coolant pipe is fixedly connected to one side of the protruding part of the outer wall of the fixed shell. The second hollow shaft movably passes through the fixed shell. An impeller is fixedly fitted on the outer wall of the fixed shell. The impeller is disposed in the inner cavity of the fixed shell. The outer end of the second hollow shaft is connected to a connecting pipe through a rotary joint. The outer end of the connecting pipe is connected to the liquid outlet at the top of the fixed shell.

[0008] By adopting the above technical solution, the grinding wheel rotates, which in turn drives the second hollow shaft to rotate, thereby driving the impeller to rotate. This creates a negative pressure in the coolant pipe, drawing the coolant into the fixed shell, and then guiding it through the outlet into the inner cavity of the connecting pipe, where it enters the second hollow shaft, thus providing coolant to the nozzle.

[0009] In a preferred embodiment of the present invention, the driving assembly includes a second slide rail, a matching second slider is fitted on the outer wall of the second slide rail, the top of the second slider is fixedly connected to a support plate, an end plate is fixedly installed on one side of the top of the second slide rail, a second electric push rod is fixedly installed on the inner side wall of the end plate, and the outer end of the push rod of the second electric push rod is fixedly connected to the support plate.

[0010] By adopting the above technical solution, the second electric actuator can drive the support plate to move, and the second slider can slide along the second slide rail, which helps to improve the stability of the support plate movement, and thus helps to improve the stability of adjusting the position of the grinding wheel.

[0011] In a preferred embodiment of the present invention, the power assembly includes a second servo motor, which is fixedly mounted on one side wall of the cage. A second gear is fixedly connected to the outer end of the transmission shaft of the servo motor. A first gear meshes with the outer wall of the second gear, and the first gear is fixedly fitted onto the outer wall of the first hollow shaft.

[0012] By adopting the above technical solution, the second servo motor can drive the second gear to rotate, thereby driving the first gear to rotate, which in turn drives the first hollow shaft to rotate, and thus drives the grinding wheel to rotate to grind the workpiece.

[0013] In a preferred embodiment of this utility model, the clamping assembly includes a first slide rail, with a matching first slider fitted on both sides of the top of the first slide rail. A vertical plate is fixedly connected to the top of the first slider. A first servo motor is fixedly installed on the outer wall of one of the vertical plates. The outer end of the drive shaft of the first servo motor movably passes through the vertical plate and is fixedly connected to a four-jaw chuck. A turntable is rotatably installed on the inner side wall of the other vertical plate. A clamping rod is fixedly installed in the middle of the outer wall of the turntable. A first electric push rod is fixedly installed at both ends of the top of the first slide rail. The outer end of the push rod of the first electric push rod is fixedly connected to the vertical plate.

[0014] By adopting the above technical solution, the workpiece is clamped and fixed by a four-jaw chuck, and then the first electric push rod drives the vertical plate to move, so that the clamping rod is pressed against the other end of the workpiece. Then, during the grinding process using the brush wheel, the first servo motor drives the four-jaw chuck to rotate, thereby driving the workpiece to rotate, and thus achieving grinding at different positions of the workpiece. Furthermore, the two first electric push rods, one retracting and the other pushing forward, can move the workpiece along the length of the first slide rail, achieving all-round grinding of the workpiece.

[0015] In a preferred embodiment of this utility model, the four-jaw chuck and the clamping rod are arranged concentrically.

[0016] In a preferred embodiment of this utility model, the outer end of the clamping rod is provided with a pointed tip.

[0017] In a preferred embodiment of this utility model, the side wall of the grinding wheel is provided with a through hole, and a hollow spline shaft is fixedly installed in the through hole. Both ends of the hollow spline shaft are detachably and fixedly connected to the first hollow shaft and the second hollow shaft respectively through flanges.

[0018] By adopting the above technical solution, when the coolant enters the inner cavity of the spline shaft, a cavity of a corresponding shape is also opened on the inner wall of the spline shaft corresponding to the spline position. This helps to increase the contact area between the coolant and the inner wall of the spline shaft, thereby increasing the contact area for heat exchange with the grinding wheel and thus improving the heat exchange effect.

[0019] In a preferred embodiment of this utility model, the width of the nozzle is greater than the width of the grinding wheel.

[0020] In a preferred embodiment of this utility model, mounting holes are provided at the four corners of the top of the base.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the rotation of the grinding wheel to drive the impeller inside the fixed housing to rotate during the grinding process. This creates a negative pressure in the coolant pipe, drawing coolant into the nozzle and guiding it along the surface of the grinding wheel. Thus, coolant can be drawn to cool the grinding wheel without the need for other power sources, thereby saving energy. The extracted coolant can enter the second hollow shaft, and then flow into the inner cavity of the hollow spline shaft. This coolant can then pass through the inner cavity of the grinding wheel, thus cooling the grinding wheel from the inside. Combined with the scouring and cooling effect on the outer wall of the grinding wheel, this improves the cooling effect and helps prevent heat buildup inside the grinding wheel, which would cause accelerated wear and tear. This helps extend the service life of the grinding wheel. Furthermore, the coolant flowing through the first hollow shaft can also carry away some of the heat from the first gear, thus cooling it down to a certain extent and reducing its wear. When coolant enters the inner cavity of the splined shaft, a cavity of a corresponding shape is also opened on the inner wall of the splined shaft corresponding to the spline position. This helps to increase the contact area between the coolant and the inner wall of the splined shaft, thereby increasing the contact area for heat exchange with the grinding wheel and thus improving the heat exchange effect.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to fixed connection or setting, detachable connection or setting, or integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The model numbers of the electrical appliances provided in this utility model are for reference only, and different models of electrical appliances with the same function can be replaced according to actual usage.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a high-temperature alloy substrate grinding device with NiCrAlY coating, including a base 1, and a clamping assembly is fixedly installed on one side of the top of the base 1. A drive assembly is installed on the other side of the top of the base 1. A support plate 2 is installed on the drive assembly. A retainer 21 is fixedly installed on one side wall of the support plate 2. A grinding wheel 22 is rotatably installed inside the retainer 21. A first hollow shaft 25 is fixedly connected to one side wall of the grinding wheel. The first hollow shaft 25 moves through the retainer 21 and is connected to a power assembly. A second hollow shaft 5 is fixedly connected to the other end of the grinding wheel 22. The second hollow shaft 5 moves through the retainer 21 and is connected to a suction assembly. A fixing frame 23 is fixedly installed on the top of the support plate 2. A nozzle 24 is fixedly connected to the bottom of the outer end of the fixing frame 23. A conduit 3 is connected to the outer end of the first hollow shaft 25 through a rotary joint. The outer end of the conduit 3 is connected to the nozzle 24.

[0028] It should be understood that in actual use, the workpiece to be ground is first clamped and fixed using the clamping assembly. Then, the drive assembly moves the support plate 2, bringing the grinding wheel 22 closer to and against the workpiece. The power assembly drives the first hollow shaft 25 to rotate, thereby rotating the grinding wheel 22. The rotating grinding wheel 22 then grinds the workpiece. During the grinding process, the second hollow shaft 5 rotates, driving the suction assembly to work and drawing coolant into the second hollow shaft 5, which then flows along the second hollow shaft 5 and through the grinding wheel 22. The coolant enters the inner cavity of the first hollow shaft 25, then flows through the guide tube 3 into the inner cavity of the nozzle 24, and is guided along the nozzle 24 to the surface of the grinding wheel 22. This achieves scouring and cooling of the grinding wheel, while also reducing the adhesion of debris to the surface of the grinding wheel 22. The coolant passes through the inner cavity of the grinding wheel 22, thus achieving cooling of the grinding wheel 22 from the inside. Combined with the scouring and cooling of the outer wall of the grinding wheel 22, this improves the cooling effect of the grinding wheel 22, thereby preventing heat accumulation inside the grinding wheel 22 that could lead to accelerated wear and tear, and ultimately extending the service life of the grinding wheel 22.

[0029] Furthermore, mounting holes are provided at the four corners of the top of the base 1, which facilitates the installation and fixation of the entire device.

[0030] Furthermore, the width of the nozzle 24 is greater than the width of the grinding wheel 22, so that the water discharged from the nozzle 24 can cover the grinding wheel 22, thereby improving the overall cooling effect.

[0031] like Figure 1 and 2 As shown; the suction assembly includes a fixed shell 51, which is fixed to one side wall of the retainer 21. A coolant pipe 53 is fixedly connected to one side of the protruding part of the outer wall of the fixed shell 51. A second hollow shaft 5 movably passes through the fixed shell 51. An impeller 54 is fixedly fitted on the outer wall of the fixed shell 51. The impeller 54 is disposed in the inner cavity of the fixed shell 51. The outer end of the second hollow shaft 5 is connected to a connecting pipe 52 through a rotary joint. The outer end of the connecting pipe 52 is connected to the liquid outlet at the top of the fixed shell 51.

[0032] It should be understood that the rotation of the grinding wheel 22 drives the second hollow shaft 5 to rotate, thereby driving the impeller 54 to rotate, which creates a negative pressure in the coolant pipe 53, thereby drawing the coolant into the fixed shell 51, and then guiding it through the outlet into the inner cavity of the connecting pipe 52, thus entering the second hollow shaft 5, thereby providing coolant to the nozzle 24.

[0033] like Figure 1 and 2 As shown; the power assembly includes a second servo motor 27, which is fixedly mounted on one side wall of the cage 21. A second gear 28 is fixedly connected to the outer end of the drive shaft of the servo motor 27. A first gear 26 meshes with the outer wall of the second gear 28. The first gear 26 is fixedly fitted onto the outer wall of the first hollow shaft 25. It should be understood that the second servo motor 27 can drive the second gear 28 to rotate, thereby driving the first gear 26 to rotate, which in turn drives the first hollow shaft 25 to rotate, thereby driving the grinding wheel 22 to rotate and grind the workpiece.

[0034] like Figure 1 and 3 As shown; the drive assembly includes a second slide rail 16, a matching second slider 17 is fitted on the outer wall of the second slide rail 16, the top of the second slider 17 is fixedly connected to the support plate 2, an end plate is fixedly installed on one side of the top of the second slide rail 16, a second electric push rod 18 is fixedly installed on the inner side wall of the end plate, and the outer end of the push rod of the second electric push rod 18 is fixedly connected to the support plate 2.

[0035] It should be understood that in actual use, the second electric actuator 18 can drive the support plate 2 to move, and the second slider 17 can slide along the second slide rail 16, which helps to improve the stability of the movement of the support plate 2, and thus helps to improve the stability of the position of the grinding wheel 22.

[0036] like Figure 1 and 3 As shown, the clamping assembly includes a first slide rail 11, with a matching first slider 12 fitted on both sides of the top of the first slide rail 11. A vertical plate 13 is fixedly connected to the top of the first slider 12. A first servo motor 14 is fixedly installed on the outer wall of one of the vertical plates 13. The outer end of the drive shaft of the first servo motor 14 movably passes through the vertical plate 13 and is fixedly connected to a four-jaw chuck 19. A turntable 6 is rotatably installed on the inner side wall of the other vertical plate 13. A clamping rod 61 is fixed in the middle of the outer wall of the turntable 6. A first electric push rod 15 is fixedly installed at both ends of the top of the first slide rail 11. The outer end of the push rod of the first electric push rod 15 is fixedly connected to the vertical plate 13.

[0037] It should be understood that in actual use, the workpiece is clamped and fixed by the four-jaw chuck 19, and then the first electric push rod 15 drives the vertical plate 13 to move, so that the clamping rod 61 is pressed against the other end of the workpiece. Then, during the grinding process using the brush wheel 22, the first servo motor 14 drives the four-jaw chuck 19 to rotate, thereby driving the workpiece to rotate, and thus achieving grinding at different positions of the workpiece. Furthermore, the two first electric push rods 15 can move the workpiece along the length direction of the first slide rail 11 by retracting one and pushing the other forward, thereby achieving all-round grinding of the workpiece. The control of the two first electric push rods 15 can be controlled by the PLC controller to make the retraction and forward pushing amounts the same, thereby ensuring stable movement of the workpiece. This technical means is a conventional technology and has not been described in detail in the text.

[0038] Furthermore, the four-jaw chuck 19 and the clamping rod 61 are concentrically arranged, which makes the rotation stable after the workpiece is clamped and positioned, and helps to avoid misalignment that could cause large internal stress and damage to the equipment.

[0039] Furthermore, the outer end of the clamping rod 61 is provided with a pointed tip, which makes the clamping stability against the end face of the workpiece high.

[0040] like Figure 1 and 6 The grinding wheel 22 has a through hole on its side wall, and a hollow spline shaft 29 is fixedly installed in the through hole. Both ends of the hollow spline shaft 29 are detachably and fixedly connected to the first hollow shaft 25 and the second hollow shaft 5 respectively through the flange 4.

[0041] It should be understood that when the coolant enters the inner cavity of the spline shaft 29, a cavity of a corresponding shape is also opened on the inner wall of the spline shaft 29 corresponding to the spline position. This helps to increase the contact area between the coolant and the inner wall of the spline shaft 29, thereby increasing the contact area for heat exchange with the grinding wheel 22, and thus improving the heat exchange effect.

[0042] Furthermore, the components included in this utility model's high-temperature alloy substrate grinding equipment with NiCrAlY coating are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching monitoring computer and power supply, are connected by wires. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a well-known technology in the field. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
