Description

Technical Field

[0001] This utility model relates to the technical field of master alloy grinding equipment, specifically a master alloy edge and corner grinding device. Background Technology

[0002] In the processing of master alloys (such as high-temperature alloys and corrosion-resistant alloys), disc-shaped castings are a widely used basic product type. After casting or preliminary forming, burrs, flash, or uneven structures often remain at the outer corners and end face joints of these castings. If they are not polished, they will not only affect the fitting accuracy during subsequent assembly, but may also cause stress concentration and accelerated wear during product use due to corner defects. Therefore, corner polishing is a key process to ensure the quality of disc-shaped master alloy castings.

[0003] A search revealed that patent publication number CN209970329U discloses a grinding device for the edges and corners of a master alloy, belonging to the technical field of metal material processing equipment. Structurally, it consists of a worktable, mounting bracket, grinding column, clamps, screw, and turntable connected together. The grinding column is driven to rotate by a motor and transmission belt. The top clamp moves up and down under the action of the lifting turntable and screw, while the bottom clamp rotates under the drive of the turntable. The master alloy to be ground is clamped between the top clamp and the bottom clamp. By moving the turntable, the edges and corners of the master alloy come into contact with the surface of the grinding column, thereby quickly completing the grinding operation of the master alloy. Because there is a gap between the through hole and the grinding column, it is convenient for chip removal from the abrasive. Compared with traditional grinding devices, the device has a novel structure, is simple to operate, safe to operate, and improves grinding quality and processing efficiency.

[0004] Existing grinding devices for master alloy edges and corners require manual centering and fixing of the disc-shaped master alloy casting when grinding its edges and corners. This manual centering can introduce errors, leading to poor edge and corner symmetry and dimensional deviations after grinding, which affects the consistency of product quality in batch processing. Furthermore, the manual centering of the disc-shaped master alloy casting is time-consuming, impacting processing efficiency. Therefore, a new grinding device for master alloy edges and corners is designed. Utility Model Content

[0005] In view of the defects or deficiencies of existing grinding devices for the edges and corners of master alloys, the purpose of this utility model is to provide a grinding device for the edges and corners of master alloys, which realizes automatic center positioning and fixing of disc-shaped master alloy castings, avoids the errors caused by manual center positioning of disc-shaped master alloy castings, and effectively ensures the accuracy of grinding the edges and corners of disc-shaped master alloy castings.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a grinding device for the edges and corners of a master alloy, including a worktable. The worktable is provided with a fixing component for fixing a disc-shaped master alloy casting and a grinding component for grinding the edges and corners of the fixed disc-shaped master alloy casting. A base plate is provided below the worktable. A center positioning component for center positioning of the disc-shaped master alloy casting placed on the worktable is provided between the worktable and the base plate. A first hydraulic telescopic rod for driving the center positioning component to move linearly in the Y-axis direction is installed at the center position of the top of the base plate.

[0008] The central positioning component is equipped with a rotating plate. The four corners of the rotating plate are movably connected to one end of four connecting rods via movable pins. The other end of each connecting rod is movably connected to a slider via a movable pin. The bottom end of the slider is mounted on a slide rail, and the top end of the slider is equipped with a positioning rod. The bottom end of the first mounting plate is equipped with a lifting frame. A connecting shaft is installed at the center of the bottom end of the rotating plate. The bottom end of the connecting shaft passes through a bearing at the center of the surface of the first mounting plate and is connected to a second reduction motor via a coupling. The second reduction motor is installed at the center of the top end of the lifting frame.

[0009] Preferably, the slider and the slide rail are slidably connected, and there are four slide rails arranged in a ring array at the top of the first mounting plate.

[0010] Preferably, a support guide column is installed at each of the four corners of the bottom of the workbench, and the bottom end of the support guide column passes through the through hole on the surface of the lifting frame and is connected to the base plate. The outer diameter of the support guide column is equal to the inner diameter of the through hole. The surface of the workbench is provided with four limiting slots arranged in a ring array. The circumferential outer wall of the positioning rod and the hole wall of the limiting slot are in clearance fit.

[0011] Preferably, the grinding assembly is provided with a rotating tube, which is located in a bearing at the center of the worktable surface. A second mounting plate is provided above one side of the outer circumferential wall of the rotating tube, and the second mounting plate is located above the worktable. A linear slide module is mounted on the top of the second mounting plate, and a grinding rod is provided on the top of the slide of the linear slide module.

[0012] Preferably, a driven gear is provided below the outer circumferential wall of the rotating tube, and the driven gear is located below the worktable. The driven gear is meshed with the driving gear, and the driving gear is mounted on the output shaft of the first reduction motor. The first reduction motor is mounted on the inner top of the connecting frame, and the connecting frame is mounted on the bottom of the worktable.

[0013] Preferably, a placement plate is provided above the workbench, and a connecting column is installed at the center of the bottom end of the placement plate. The bottom end of the connecting column passes through the interior of the rotating tube and is connected to the connecting frame.

[0014] Preferably, the fixing component is provided with a mounting bracket, which is installed on the rear end of the upper surface of the workbench. A second hydraulic telescopic rod is installed at the front end of the top of the mounting bracket. The telescopic end of the second hydraulic telescopic rod passes through the mounting bracket and is connected to the fixing plate, and the fixing plate is located directly above the placement plate.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] In this utility model, through a series of coordinated structural arrangements, when the worker is grinding the edges and corners of a disc-shaped master alloy casting, after placing the disc-shaped master alloy casting on the top of the placement plate, the worker activates the first hydraulic telescopic rod, causing it to move the central positioning component to a certain horizontal height in the Y-axis direction. Then, the positioning rod on the central positioning component passes through the limiting slot on the worktable, and there is a certain gap between the top of the positioning rod and the top of the worktable. At this point, the worker activates the second reduction motor on the central positioning component. The activation of the second reduction motor indirectly causes the four positioning rods to move inward along the limiting slot. When the rod moves inward, it centers the disc-shaped master alloy casting on the placement plate. After the disc-shaped master alloy casting is centered, the operator activates the second hydraulic telescopic rod on the fixing assembly, causing the second hydraulic telescopic rod to drive the fixing plate to clamp the disc-shaped master alloy casting on the placement plate. Thus, this invention achieves automatic center positioning and fixing of the disc-shaped master alloy casting, avoiding errors caused by manual center positioning of the disc-shaped master alloy casting. This effectively ensures the accuracy of grinding the edges and corners of the disc-shaped master alloy casting, reduces product defects caused by positioning deviations, improves the consistency of product quality in batch processing, and also improves processing efficiency.

[0017] In this invention, through a series of coordinated structural arrangements, the center positioning component and the fixing component work together to center and fix disc-shaped master alloy castings of different outer diameters. When grinding the fixed disc-shaped master alloy castings, the operator activates the first hydraulic telescopic rod, causing the center positioning component to move downwards in the Y-axis direction. After the center positioning component is positioned below the worktable, the operator activates the linear slide module, causing the grinding rod to contact the edge of the disc-shaped master alloy casting. Then, the operator activates the first reduction motor on the grinding component. The activation of the first reduction motor indirectly drives the grinding rod to rotate along the edge of the disc-shaped master alloy casting and grind it. This allows for edge grinding operations on disc-shaped master alloy castings of different outer diameters, enhancing versatility and facilitating operation for the operator.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0037] like Figure 1-7 As shown, a mother alloy edge grinding device includes a worktable 300, a fixing component 100 for fixing a disc-shaped mother alloy casting and a grinding component 200 for grinding the edges of the fixed disc-shaped mother alloy casting on the worktable 300, a base plate 500 below the worktable 300, a center positioning component 700 for center positioning of the disc-shaped mother alloy casting placed on the worktable 300 between the worktable 300 and the base plate 500, and a first hydraulic telescopic rod 600 for driving the center positioning component 700 to move linearly in the Y-axis direction at the center position of the top of the base plate 500.

[0038] A rotating plate 720 is provided on the center positioning component 700. The four corners of the rotating plate 720 are movably connected to one end of four connecting rods 710 via movable pins. The other end of each connecting rod 710 is movably connected to a slider 740 via a movable pin. The bottom end of the slider 740 is mounted on a slide rail 750, and a positioning rod 730 is provided at the top end of the slider 740. A lifting frame 760 is provided at the bottom end of the first mounting plate 770. A connecting shaft 780 is installed at the center of the bottom end of the rotating plate 720, and the bottom end of the connecting shaft 780 passes through... The bearing at the center of the surface of the first mounting plate 770 is connected to the second geared motor 790 via a coupling. The second geared motor 790 is mounted at the center of the top of the lifting frame 760. When the second geared motor 790 starts, it drives the rotating plate 720 to rotate via the connecting shaft 780. When the rotating plate 720 rotates, it drives the slider 740 to move linearly on the slide rail 750 via the connecting rod 710. When the slider 740 moves linearly on the slide rail 750, it drives the positioning rod 730 to move linearly in a certain direction.

[0039] The slider 740 is slidably connected to the slide rail 750. There are four slide rails 750, and the four slide rails 750 are arranged in a ring array at the top of the first mounting plate 770.

[0040] Support guide columns 400 are installed at the four corners of the bottom of the workbench 300. The bottom of the support guide column 400 passes through the through hole on the surface of the lifting frame 760 and is connected to the base plate 500. The outer diameter of the support guide column 400 is equal to the inner diameter of the through hole. Because the outer diameter of the support guide column 400 is equal to the inner diameter of the through hole, it can limit and guide the movement of the center positioning component 700. The surface of the workbench 300 is provided with four limiting slots 340 arranged in a ring array. The circumferential outer wall of the positioning rod 730 is clearance-fitted with the hole wall of the limiting slot 340. Because the circumferential outer wall of the positioning rod 730 is clearance-fitted with the hole wall of the limiting slot 340, the movement of the positioning rod 730 can be limited when it moves in the limiting slot 340.

[0041] The grinding assembly 200 is provided with a rotating tube 230, which is located in a bearing at the center of the surface of the worktable 300. A second mounting plate 270 is provided above the outer side of the rotating tube 230 and is located above the worktable 300. A linear slide module 220 is installed on the top of the second mounting plate 270. A grinding rod 210 is provided on the top of the slide of the linear slide module 220. When the linear slide module 220 is started, it will drive the grinding rod 210 to move linearly in a certain direction.

[0042] A driven gear 240 is provided on the lower part of the outer circumferential wall of the rotating tube 230, and the driven gear 240 is located below the worktable 300. The driven gear 240 is meshed with the driving gear 250, and the driving gear 250 is mounted on the output shaft of the first reduction motor 260. The first reduction motor 260 is mounted on the inner top of the connecting frame 330, and the connecting frame 330 is mounted on the bottom of the worktable 300. When the first reduction motor 260 starts, it drives the driving gear 250 to rotate. When the driving gear 250 rotates, it drives the driven gear 240 to rotate. When the driven gear 240 rotates, it drives the rotating tube 230 to rotate. When the rotating tube 230 rotates, it drives the second mounting plate 270 to rotate. When the second mounting plate 270 rotates, it drives the grinding rod 210 on the linear slide module 220 to rotate.

[0043] A placement plate 310 is provided above the workbench 300. A connecting column 320 is installed at the center of the bottom end of the placement plate 310. The bottom end of the connecting column 320 passes through the interior of the rotating tube 230 and is connected to the connecting frame 330.

[0044] The fixed component 100 is provided with a mounting bracket 110, which is installed on the rear end of the upper surface of the workbench 300. A second hydraulic telescopic rod 120 is installed on the front end of the top of the mounting bracket 110. The telescopic end of the second hydraulic telescopic rod 120 passes through the mounting bracket 110 and is connected to the fixing plate 130, and the fixing plate 130 is located directly above the placement plate 310.

[0045] Working principle: When in use, after connecting to an external power source, when the operator is grinding the edges of the disc-shaped master alloy casting, the operator places the disc-shaped master alloy casting on the top of the placement plate 310. The operator then activates the first hydraulic telescopic rod 600, causing it to move the center positioning component 700 to a certain horizontal height in the Y-axis direction. The positioning rod 730 on the center positioning component 700 then passes through the limiting slot 340 on the worktable 300, and there is a certain gap between the top of the positioning rod 730 and the top of the worktable 300. The operator then activates the... The second reduction motor 790 on the center positioning assembly 700 indirectly causes the four positioning rods 730 to move inward along the limiting slot 340. As the four positioning rods 730 move inward, they center the disc-shaped master alloy casting on the placement plate 310. After the disc-shaped master alloy casting is centered, the operator activates the second hydraulic telescopic rod 120 on the fixing assembly 100, causing the second hydraulic telescopic rod 120 to drive the fixing plate 130 to clamp the disc-shaped master alloy casting on the placement plate 310. Thus, this utility model achieves the center positioning of the disc-shaped master alloy casting. The automatic centering and fixing of the disc-shaped master alloy casting avoids errors caused by manual centering, effectively ensuring the precision of edge grinding, reducing product defects caused by positioning deviations, improving product quality consistency in batch processing, and increasing processing efficiency. The cooperation between the centering component 700 and the fixing component 100 enables the centering and fixing of disc-shaped master alloy castings with different outer diameters. When grinding the fixed disc-shaped master alloy casting, the operator activates the first hydraulic telescopic rod 600 to... After the center positioning component 700 moves downward in the Y-axis direction and is positioned below the worktable 300, the operator starts the linear slide module 220 and makes the grinding rod 210 contact the edge of the disc-shaped master alloy casting. Then, the first reduction motor 260 on the grinding component 200 is started. The start of the first reduction motor 260 will indirectly drive the grinding rod 210 to rotate along the edge of the disc-shaped master alloy casting and grind it. This allows for edge grinding operations on disc-shaped master alloy castings of different outer diameters, enhancing versatility and facilitating operation for the operator.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
