Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically a grinding wheel structure for grinding metal parts. Background Technology

[0002] During the manufacturing process of metal parts, defects in the process and equipment may result in burrs on the surface of the formed metal parts, which usually require grinding. Grinding is a surface modification technique, generally referring to a processing method that uses a rough object to change the physical properties of the material surface through friction, with the main purpose of obtaining a specific surface roughness. Grinding wheels are common grinding tools. A motor drives the grinding wheel to rotate and rub against the surface of the workpiece, making the surface of the workpiece smoother.

[0003] Patent document CN219704653U discloses a grinding wheel structure for grinding metal parts, including a mounting structure and a grinding wheel body. A connector is fixedly mounted at one end of the mounting structure, and a mounting rod is fixedly connected to the back end of the grinding wheel body. The mounting rod passes through the connector and engages with the internal movable part of the mounting structure. By using the mounting structure, a sliding arc plate slides along the surface of the mounting tube, causing the movable ring to drive the fixing pin to gradually penetrate or move away from the mounting notch on the surface of the mounting rod. This allows for quick assembly and disassembly of the mounting rod via a placement block and mounting tube. By avoiding the use of bolts and nuts, and employing a mortise and tenon structure for assembly and disassembly, the entire process only requires moving the sliding arc plate, saving time and effort and improving the convenience of disassembly and replacement. However, the existing technology still has shortcomings:

[0004] In existing technologies, grinding wheels are installed and removed by simply engaging a single fixing pin with an installation notch on the surface of the mounting rod. During installation, the connecting rod of the grinding wheel body to be installed is passed through the insertion tube and inserted into the mounting tube. During the installation process, the operator needs to rotate and adjust the angle of the connecting rod to align the mounting pin at the bottom of the movable arc plate with the installation notch. This makes the installation process inconvenient and reduces the efficiency of disassembly and replacement. Furthermore, the single fixing pin engagement method results in poor stability of the grinding wheel during use, affecting the grinding effect of the grinding machine and making it inconvenient to use.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a grinding wheel structure for grinding metal parts.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a grinding wheel structure for grinding metal parts, comprising:

[0008] A grinding wheel body, wherein a mounting rod is fixedly connected to the back end of the grinding wheel body;

[0009] The mounting tube is located at one end of the mounting rod;

[0010] A guide structure is provided inside the mounting tube. The guide structure includes four guide grooves formed on the inner wall of the mounting tube and distributed circumferentially around the mounting tube. A guide block that cooperates with the guide grooves is fixedly connected to the outer wall of the mounting rod.

[0011] The mounting structure is located inside the mounting tube. The mounting structure includes four cavities formed within the mounting tube and arranged circumferentially around the mounting tube. Four slots are formed on the outer wall of the mounting rod to mate with the cavities, also arranged circumferentially around the mounting rod. Mounting pins are inserted at both ends of the cavity, and pressure plates are fixedly connected to the mounting pins. A spring is fixedly connected between the pressure plate and the inner wall of the cavity, located on the side of the pressure plate closest to the slot. A trapezoidal block is fixedly connected to the end of the mounting pin furthest from the slot.

[0012] A fixed structure is provided outside the mounting tube. The fixed structure includes a movable ring sleeved on the outside of the mounting tube. A cavity two is formed inside the movable ring. An opening is formed at the end of the cavity two away from the grinding wheel body. A guide slope is provided on the side of the opening away from the mounting tube. Rectangular grooves are formed at both ends of the inner wall of the cavity two. Guide rods are fixedly connected to both ends of the inner wall of the rectangular grooves. A movable plate is slidably connected to the guide rods. A spring two is fixedly connected between the movable plate and the inner wall of the cavity two near the mounting tube. The spring two is sleeved outside the guide rods. A button is fixedly connected to the top of the movable plate. The button is inserted through the outer wall of the movable ring.

[0013] Furthermore, the trapezoidal block has a lifting hole on its side.

[0014] Furthermore, the outer wall of the mounting tube is provided with four sliding grooves that are distributed circumferentially around the mounting tube, and a slider that cooperates with the sliding groove is fixedly connected to the inner wall of the movable ring.

[0015] Furthermore, a connecting plug is fixedly installed at the end of the mounting tube away from the grinding wheel body.

[0016] The advantages of this invention compared to existing technologies are as follows: Through the arrangement of the guide structure, installation structure, and fixing structure, during installation, the guide block on the mounting rod is aligned with the guide groove on the mounting tube and inserted. Then, the movable ring slides, allowing it to slide within the groove via the slider. At this time, the guide slope of the movable ring gradually contacts the slope of the trapezoidal block, causing the trapezoidal block to move downwards within cavity one, compressing spring one, and subsequently engaging the mounting pin in the slot until the trapezoidal block is fully inserted into cavity two. Then, under the elastic action of spring one, the trapezoidal block moves upwards and presses against the bottom of the movable plate. At this point, the positions of the four sets of mounting pins are simultaneously... The fixed design ensures high stability in the installation and positioning of the grinding wheel. Disassembly is simple: press four buttons. The buttons cause the movable plate to slide on the guide rod, compressing spring two. This, in turn, moves the trapezoidal block. Then, sliding the movable ring resets it. Under the elasticity of spring one, the mounting pin disengages from the slot, allowing the mounting rod to be removed from the mounting tube. Since the guide groove, guide block, slot, mounting pin, and buttons are all arranged in four circumferentially, there is no need to rotate the mounting rod to adjust the angle during installation. Simply sliding the movable ring automatically completes the engagement, making the installation and disassembly process simpler and faster, thus improving work efficiency during replacement.

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1 to 6 As shown, this embodiment proposes a grinding wheel structure for grinding metal parts, including a grinding wheel body 1, a mounting rod 2 fixedly connected to the back end of the grinding wheel body 1, and a mounting tube 3 provided at one end of the mounting rod 2.

[0027] The mounting tube 3 has a guide structure 4 inside. The guide structure 4 includes four guide grooves 41 on the inner wall of the mounting tube 3, which are distributed in a circle around the mounting tube 3. The outer wall of the mounting rod 2 is fixedly connected with a guide block 42 that works with the guide grooves 41. During installation, the guide block 42 on the mounting rod 2 is aligned with the guide groove 41 on the mounting tube 3 and inserted. Since the four sets of guide grooves 41 and guide blocks 42 are distributed in a circle, there is no need to repeatedly adjust the angle during insertion.

[0028] The mounting tube 3 has an internal mounting structure 5, which includes four cavities 51 arranged circumferentially around the mounting tube 3. The outer wall of the mounting rod 2 has four slots 52 that cooperate with the cavities 51. The mounting pins 53 are inserted at both ends inside the cavities 51. A pressure plate 54 is fixedly connected to the mounting pins 53. A spring 55 is fixedly connected between the pressure plate 54 and the inner wall of the cavities 51. The spring 55 is located on the side of the pressure plate 54 near the slots 52. A trapezoidal block 56 is fixedly connected to the end of the mounting pin 53 away from the slots 52. A lifting hole 561 is provided on the side of the trapezoidal block 56. The lifting hole 561 facilitates manual lifting of the mounting pin 53. When no external force is applied, the mounting pin 53 does not contact the slots 52 due to the elasticity of the spring 55.

[0029] The mounting tube 3 is externally provided with a fixing structure 6, which includes a movable ring 61 sleeved on the outside of the mounting tube 3. Four grooves 611 are formed on the outer wall of the mounting tube 3 and are distributed circumferentially around the mounting tube 3. A slider 612, which cooperates with the groove 611, is fixedly connected to the inner wall of the movable ring 61. The slider 612 slides within the groove 611, facilitating the movement and limiting the movement of the movable ring 61, making its movement more stable. A cavity 62 is formed inside the movable ring 61. An opening 63 is formed at the end of the cavity 62 away from the grinding wheel body 1. A guide slope 64 is provided on the side of the opening 63 away from the mounting tube 3. The guide slope 64 gradually contacts the slope of the trapezoidal block 56, causing the trapezoidal block 56 to move the pressure plate 54 downwards within the cavity 51 and compress the spring 55, thereby driving the mounting pin 53. The trapezoidal block 56 is inserted into the slot 52 until it is fully inserted into the cavity 62. The inner wall of the cavity 62 has rectangular grooves 65 at both ends. Guide rods 66 are fixedly connected to the inner walls of the rectangular grooves 65. A movable plate 68 is slidably connected to the guide rods 66. A spring 67 is fixedly connected between the movable plate 68 and the inner wall of the cavity 62 near the mounting tube 3. The spring 67 is sleeved on the outside of the guide rods 66. A button 69 is fixedly connected to the top of the movable plate 68. The button 69 is inserted into the outer wall of the movable ring 61. When disassembling, simply press all four sets of buttons 69. The buttons 69 drive the movable plate 68 to slide on the guide rods 66 and squeeze the spring 67. Then the movable plate 68 drives the trapezoidal block 56 to move. After that, the movable ring 61 is slid to reset it. Under the elastic action of the spring 55, the mounting pin 53 is disengaged from the slot 52. At this time, the mounting rod 2 can be removed from the mounting tube 3.

[0030] A connecting plug 7 is fixedly installed at the end of the mounting tube 3 away from the grinding wheel body 1. The mounting tube 3 is connected to the output shaft of the grinding motor through the connecting plug 7.

[0031] In practical implementation, this utility model is used by first aligning the guide block 42 on the mounting rod 2 with the guide groove 41 on the mounting tube 3 and inserting it. Then, the movable ring 61 is slid, allowing it to slide within the slide groove 611 via the slider 612. At this time, the guide slope 64 of the movable ring 61 gradually contacts the slope of the trapezoidal block 56, causing the trapezoidal block 56 to move the pressure plate 54 downward within the cavity 1 51 and compress the spring 1 55. This, in turn, causes the mounting pin 53 to engage with the slot 52 until the trapezoidal block 56 is fully inserted into the cavity 2 62. Then, under the elastic action of the spring 1 55, the trapezoidal block 56 moves upward and presses against the bottom of the movable plate 68. At this time, the positions of the four sets of mounting pins 53 are simultaneously fixed. During disassembly, simply press the four sets of buttons 69. The buttons 69 drive the movable plate 68 to slide on the guide rod 66 and compress the second spring 67. In turn, the movable plate 68 drives the trapezoidal block 56 to move. Then, slide the movable ring 61 to reset it. Under the elastic action of the first spring 55, the mounting pin 53 disengages from the slot 52. At this point, the mounting rod 2 can be removed from the mounting tube 3. Since the guide groove 41, guide block 42, slot 52, mounting pin 53, and buttons 69 are all arranged in four circumferentially, there is no need to rotate the mounting rod 2 to adjust the angle during installation. Simply slide the movable ring 61 to automatically complete the engagement. The installation and disassembly process is simpler and faster, improving the work efficiency during disassembly and replacement, and has good practicality.
