Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for aviation alloy parts. Background Art

[0002] The manufacturing process of an aviation alloy part involves multiple delicate steps. First, it is necessary to select suitable alloy materials that have high strength, high temperature resistance and corrosion resistance to ensure that aviation parts can maintain performance in extreme environments. After selecting the material, the next step is the smelting process of the alloy. This step requires precise control of the melting temperature to ensure that the alloy's composition is evenly distributed to achieve the required performance standards. Next, the smelted alloy needs to undergo a forming process such as casting or extrusion to form the desired part shape. During this process, process parameters such as temperature, pressure and speed need to be strictly controlled to ensure the dimensional accuracy and internal structural integrity of the parts.

[0003] In addition, the formed parts need to undergo subsequent heat treatment processes, such as solution treatment and aging treatment, to further optimize their mechanical properties. After completing the heat treatment, aviation alloy parts also need to be machined to remove excess material and accurately machine the required size and shape. Machining includes milling, turning, drilling, grinding, polishing and other processing methods. In the manufacture of aviation parts, some parts need to be welded and assembled for use. After welding, the welds need to be ground or polished to ensure that the surface quality of aviation parts reaches extremely high standards.

[0004] A welding seam grinding device is disclosed in the patent "Automatic grinding device for welding seams of aluminum alloy plates" (publication number CN209681827U, hereinafter referred to as prior art 1). Prior art 1 realizes automatic grinding of welding seams of aluminum alloy plates by means of a cart and a detachable axle seat. The cart includes a chassis, wheels connected to four feet on the bottom surface of the chassis, and a handrail connected to the rear of the chassis; one end of the fixed axle seat is connected to the end surface of one side of the front of the chassis, and one end of the detachable axle seat is connected to the end surface of the other side of the front of the chassis; the middle part of the rotating shaft is connected to the front part of the channel steel through a bearing, and the two ends of the rotating shaft are connected to the fixed axle seat and the detachable axle seat respectively, and the fixed end of the angle grinder is connected to the inner end surface of the channel steel; the front part of the handle is connected to the fixed end of the angle grinder, the middle part of the handle is connected to the connecting plate, and the rear part of the handle is located above the rear cross beam of the chassis; the upper part of the connecting plate is connected to the inner end surface of the channel steel. In the prior art 1, the workpiece to be polished is placed at the bottom of the device, and the mobile device is used for polishing. The cart needs to be pushed to complete the polishing, and only flat welds can be polished. In addition, since the angle grinder in the prior art 1 is relatively large, the details during polishing cannot be polished in place. Utility Model Content

[0028] Example 1

[0029] See also Figure 1 The embodiment of the utility model provides an aviation alloy part grinding device, including a frame 100 and a grinding mechanism. The frame 100 is used as a carrier to install various parts of the grinding device, including the grinding mechanism.

[0030] The rack 100 is provided with a plurality of support legs 110, and both sides of the top and bottom of the plurality of support legs 110 are connected by cross beams 120. The rack 100 is composed of a plurality of support legs 110 and cross beams 120, the support legs 110 are used as supports in the vertical direction, the cross beams 120 connect the plurality of support legs 110 together, and the cross beams 120 are arranged at both ends and both sides of the support legs 110 to form a complete rack 100. A connecting beam 130 is also arranged between the two cross beams 120 at the top of the rack 100, and the connecting beam 130 connects the cavity parts between the cross beams 120. The connected rack 100 can be provided with more installation positions.

[0031] See also Figure 3 , the grinding mechanism is hinged with the connecting beam 130, the grinding mechanism is installed through the connecting beam 130, and is rotatably connected with the connecting beam 130, and the connecting beam 130 can rotate based on the hinged position. The grinding mechanism includes a mounting plate 210, a motor 220 and a mounting frame 230 arranged on the mounting plate 210; a first bracket 231 and a second bracket 232 are respectively arranged on both sides of the mounting frame 230. The mounting plate 210 is used as a mounting substrate, and the motor 220 and the mounting frame 230 are both arranged on it. The motor 220 is arranged at one end of the mounting plate 210, and the mounting frame 230 is arranged at the other end of the mounting plate 210. The motor 220 is fixedly connected to the mounting frame 230 and the mounting plate 210. Fastening screws are arranged on both sides of the motor 220 and the mounting frame 230, and the motor 220 and the mounting frame 230 are firmly installed by multiple sets of fastening screws. The motor 220 will not fall off due to the vibration when it is working. Furthermore, a buffer plate is provided between the motor 220 and the mounting plate 210, and the buffer plate can slow down the vibration of the motor 220 when it is working, and can also reduce the noise generated by the motor 220 when it is working.

[0032] See also Figure 1 and Figure 2The output shaft of the motor 220 is provided with a first grinding wheel 221, and the first bracket 231 and the second bracket 232 are provided with a second grinding wheel 233 between the ends away from the motor 220. The first grinding wheel 221 is installed through the output shaft of the motor 220, and the first grinding wheel 221 is fixedly connected to the output shaft of the motor 220. The first bracket 231 and the second bracket 232 are respectively fixedly connected to the two sides of the mounting frame 230, and further, the first bracket 231 and the second bracket 232 are integrally arranged with the mounting frame 230. The first mounting frame 230 and the second mounting frame 230 can be arranged at a certain inclined angle, or can be arranged in a straight line.

[0033] See also Figure 2 , a grinding belt 240 is sleeved on the first grinding belt wheel 221 and the second grinding belt wheel 233; the frame 100 is provided with a first cylinder 140 at one end close to the motor 220. The grinding mechanism grinds the workpiece to be polished by means of a grinding belt 240, and the grinding belt 240 is sleeved on the first grinding belt wheel 221 and the second grinding belt wheel 233. The first grinding belt wheel 221 is provided with a belt groove; the position of the grinding wheel belt is limited by the belt groove. The second grinding belt wheel 233 can be provided with a belt groove. The third grinding belt wheel 241 described below is also provided with a belt groove. The grinding belt 240 is used to grind the workpiece to be polished to remove impurities and uneven parts on its surface and make its surface smoother.

[0034] The function of the first cylinder 140 is to control the degree of contact between the sanding belt 240 and the workpiece to be polished, so that it can be effectively polished. In this polishing mechanism, the sanding belt 240 is sleeved on the first sanding belt wheel 221 and the second sanding belt wheel 233. In this way, when the first sanding belt wheel 221 and the second sanding belt wheel 233 rotate, the sanding belt 240 will also move accordingly, thereby polishing the workpiece. The belt groove provided on the first sanding belt wheel 221 limits the position of the sanding belt 240 to prevent it from shifting during operation. In this way, the polishing effect will be more accurate and stable.

[0035] See also Figure 1, the first piston rod 141 of the first cylinder 140 is connected to the mounting plate 210 through a connecting plate 150. The first piston rod 141 and the connecting plate 150 are fixedly or rotationally connected, and the connecting plate 150 and the mounting plate 210 are fixedly connected. When the first piston rod 141 and the connecting rod are fixedly connected, the extension and retraction of the first piston rod 141 will directly affect the hinged position relationship between the mounting plate 210 and the connecting plate 150, and the influence is relatively large. When the first piston rod 141 and the connecting plate 150 are hinged, when the first piston rod 141 is extended and retracted, the lifting amplitude of the mounting plate 210 by the connecting plate 150 will be relatively slow, and the influence on the rotation amplitude of its grinding mechanism will be relatively small, so that the grinding mechanism can rotate slowly.

[0036] When the piston rod is fixedly connected to the connecting plate 150, the expansion and contraction of the piston rod will directly affect the hinge position relationship between the mounting plate 210 and the connecting plate 150. This influence is significant because the expansion and contraction of the piston rod will be directly transmitted to the connecting plate 150, thereby affecting the position of the mounting plate 210. This direct influence has a large amplitude and can quickly change the position of the mounting plate 210.

[0037] See also Figure 1 When the piston rod is hinged to the connecting plate 150, the extension and retraction of the piston rod will have a relatively slow effect on the lifting range of the connecting plate 150 on the mounting plate 210. In other words, when the piston rod is extended and retracted, the lifting range of the connecting plate 150 on the mounting plate 210 will not be too fast, so that the rotation range of the grinding mechanism will not be greatly affected. In this way, the grinding mechanism can rotate slowly, thereby better completing the grinding task.

[0038] Example 2

[0039] See also Figure 1 The embodiment of the utility model provides an aviation alloy parts grinding device, wherein the first bracket 231 and the second bracket 232 respectively have a first displacement groove 234 and a second displacement groove 235 which are arranged through at one end away from the motor 220 .

[0040] The two displacement grooves are designed to better adapt to and adjust the position of the pulley bracket 238 during the movement of the pulley bracket 238, so as to ensure the stability and accuracy of the pulley bracket 238 during operation. The first displacement groove 234 and the second displacement groove 235 are provided so that the pulley bracket 238 has a larger range of motion and flexibility at the end away from the motor 220, which helps to improve the operating efficiency and stability of the entire device. At the same time, through a reasonable structural setting, the friction and wear of the sanding belt 240 during operation can be reduced, thereby extending the service life of the device.

[0041] See also Figure 4 The first bracket 231 and the second bracket 232 are provided with a tensioning mechanism at the end away from the motor 220; the tensioning mechanism includes a second cylinder 236; the end of the second piston rod 237 of the second cylinder 236 is connected to a pulley bracket 238; the second grinding belt wheel 233 is installed through the grinding belt shaft 239 in the pulley bracket 238.

[0042] The first bracket 231 and the second bracket 232 are provided with a tensioning mechanism at the end far from the motor 220, and the tensioning mechanism plays a key role in the grinding work of the grinding belt 240. The tensioning mechanism mainly includes a second cylinder 236, which is an indispensable part of the whole mechanism; in the second cylinder 236, the end of the second piston rod 237 is connected with a pulley bracket 238, such a design makes the whole mechanism more stable during operation; and the second grinding belt wheel 233 is installed through the grinding belt shaft 239 in the pulley bracket 238, such an installation method is not only convenient and fast, but also can ensure the stable operation of the grinding belt wheel. The two ends of the grinding belt shaft 239 are respectively arranged in the first displacement groove 234 and the second displacement groove 235. In this way, the second grinding wheel can move in the first displacement groove 234 and the second displacement groove 235, so as to adjust the tension of the grinding belt 240.

[0043] See also Figure 1 During the use, the sanding belt 240 may be worn and stretched due to long-term rotation. At this time, the sanding belt 240 will sag due to its own lengthening and gravity will be concentrated in the middle of the sanding belt 240, increasing the wrap angle between the first and second sanding wheels and reducing the friction between them, which will deteriorate the sanding effect and reduce the work quality. Therefore, a tensioning wheel is used to tighten the sanding belt 240 that is not completely damaged so that the friction during processing will not be too small and the processing quality will remain unchanged.

[0044] Preferably, the second cylinder 236 drives the second piston rod 237 to extend, drives the sanding belt shaft 239 to move in the first displacement groove 234 and the second displacement groove 235, and the second sanding belt wheel 233 moves away from the motor 220 based on the pulley bracket 238, and the sanding belt 240 is tightened. The second cylinder 236 pushes the second piston rod 237 to extend by applying force, thereby causing the sanding belt shaft 239 to translate between the first displacement groove 234 and the second displacement groove 235, so as to adjust the gap between the second sanding belt wheel 233 and the sanding belt 240. In this process, the second sanding belt wheel 233 slides in the direction away from the motor 220 with the support of the pulley bracket 238, so that the sanding belt 240 remains in a tight state, so that it can better play its grinding role in the subsequent use process.

[0045] See also Figure 1 , the second cylinder 236 drives the second piston rod 237 to contract, drives the sanding belt shaft 239 to move in the first displacement groove 234 and the second displacement groove 235, and the second sanding belt wheel 233 moves toward the direction close to the motor 220 based on the pulley bracket 238, and the sanding belt 240 is relaxed. The second cylinder 236 applies force to make the second piston rod 237 contract inward, thereby driving the sanding belt shaft 239 to move between the first displacement groove 234 and the second displacement groove 235. In this process, the second sanding belt wheel 233 is translated toward the direction close to the motor 220 under the action of the pulley bracket 238. At the same time, in order to ensure that the sanding belt can move smoothly, the sanding belt 240 needs to be properly relaxed. In this way, the entire sanding belt system can achieve the displacement of the sanding belt shaft 239 and the movement of the sanding belt wheel under the drive of the second cylinder 236, thereby completing the required grinding operation. Generally, the sanding belt 240 is loosened when it is disassembled or installed. When the damaged sanding belt 240 needs to be disassembled, the metal is loosened and the sanding belt 240 is replaced. The second piston rod 237 is extended and the sanding belt 240 is tightened before processing.

[0046] Example 3

[0047] See also Figure 1, an embodiment of the utility model provides an aviation alloy parts grinding device. Furthermore, a receiving frame 160 is provided on the top of the frame 100; the receiving frame 160 is used to receive the workpiece to be ground. The workpiece to be ground is arranged on the receiving frame 160, and the receiving frame 160 and the frame 100 are movably assembled. The workpiece to be ground can be a rectangular plate or a hollow cylinder. By placing it on the receiving frame 160, the receiving frame 160 is driven to move in the direction close to the grinding mechanism, so that the sanding belt 240 contacts the grinding surface of the workpiece to be ground and then performs the grinding operation. The receiving frame 160 continues to move slowly in the direction close to the grinding mechanism to complete the overall operation.

[0048] Furthermore, the receiving frame 160 is a receiving plate, and the workpiece to be polished can be processed by fastening it on the receiving plate. The receiving frame 160 is a fixture, and the workpiece to be polished can be better clamped and positioned by the fixture. The receiving frame 160 is movably connected to the frame 100 through a guide rail 170 and a plurality of slide blocks 180, and the continuous polishing operation is completed through the cooperation of the guide rail 170 and the slide blocks 180. The receiving frame 160 can also be provided with an automatic feeding device, such as a cylinder pusher.

[0049] See also Figure 1 and Figure 3 , these workpieces to be processed can be rectangular plates polished by the sanding belt 240, or hollow cylindrical components. According to different sanding requirements, the shapes and sizes of the workpieces can be diversified. In order to achieve efficient and convenient sanding operations, the receiving device is placed on the top of the frame 100, and a flexible and movable assembly structure is designed between the frame 100. This design allows the workpiece to be sanded to be easily placed on the receiving device, and also facilitates accurate positioning during the sanding process. When performing the sanding operation, first place the workpiece to be sanded on the receiving device steadily, and then start the moving mechanism to drive the receiving device to move smoothly in the direction close to the sanding mechanism. As the receiving device moves, the workpiece to be sanded gradually contacts the sanding belt 240 of the sanding mechanism, and the sanding operation begins at this time. The entire sanding process is a continuous process, and the receiving device will continue to and slowly approach the sanding mechanism until the predetermined sanding operation is completed or the sanding requirements are met. In this way, the uniformity and integrity of the grinding operation can be ensured, the grinding quality can be improved, and the safety and convenience of the operation can be guaranteed.

[0050] See also Figure 4 A third grinding wheel 241 is further provided in the middle part between the first bracket 231 and the second bracket 232 ; the third grinding wheel 241 rotates based on the first bracket 231 and the second bracket 232 through the cooperation of the rotating shaft 242 and the bearing 243 .

[0051] A third grinding belt wheel 241 is provided at the connection part between the first bracket 231 and the second bracket 232; the function of the third grinding belt wheel 241 is to precisely match the rotating shaft 242 with the bearing 243 so that the grinding belt 240 can be set through the third grinding belt wheel 241 and perform grinding operations, thereby playing the role of an intermediate wheel to increase the movement and working efficiency of the grinding belt 240.

[0052] See also Figure 5 A sanding belt guard 250 is also provided on the top of the sanding belt 240; the sanding belt guard 250 covers the top of the sanding belt 240. A sanding belt guard 250 is also installed on the top of the sanding belt 240; the function of this sanding belt guard 250 is to completely cover and protect the top of the sanding belt 240. The design of this sanding belt guard 250 can not only protect the top of the sanding belt 240 from external damage and extend the service life of the sanding belt 240, but also prevent the heat generated by friction on the top of the sanding belt 240 from harming the operator during the sanding process, ensuring safety during use.

[0053] Preferably, the mounting plate 210 and the connecting plate 150 are respectively provided with a first articulated seat 211 and a second articulated seat 151; the mounting plate 210 and the connecting plate 150 are articulated through the cooperation between the first articulated seat 211 and the second articulated seat 151; after the first cylinder 140 drives the extension and retraction of the first piston rod 141, the grinding mechanism is lifted or pressed down based on the articulation of the mounting plate 210 and the connecting plate 150.

[0054] More preferably, the mounting plate 210 and the connecting plate 150 of the present invention are respectively equipped with a first hinge seat 211 and a second hinge seat 151; through these hinge seats, the mounting plate 210 and the connecting plate 150 can be hinged by precise matching. This design allows the mounting plate 210 and the connecting plate 150 to flexibly rotate and adjust their positions between the first hinge seat 211 and the second hinge seat 151, so that the grinding mechanism can contact the workpiece to be polished. In addition, the first cylinder 140 is responsible for driving the telescopic movement of the first piston rod 141, so that the grinding mechanism can be lifted or pressed down according to the hinge action of the mounting plate 210 and the connecting plate 150. This mechanism design enables the grinding mechanism to more flexibly adapt to different working angles and positions when performing grinding operations, thereby improving grinding efficiency and quality.
