Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing device technology, specifically a polishing device with protection. Background Technology
[0002] In the modern process of surface treatment of large machinery, grinding machines are a commonly used surface treatment equipment. A grinding machine is a device that uses a high-speed rotating grinding head to grind the surface of a machine. During the grinding process, the grinding wheel rotates at high speed and comes into contact with the surface of the workpiece, thereby removing burrs and protrusions from the surface of the workpiece.
[0003] However, in modern workpiece processing, the high-speed rotation of the grinding wheel removes burrs and uneven excess material from the workpiece. During the grinding process, while the high-speed rotation grinds away the burrs, the centrifugal force causes the burrs and scrap to fly out at high speed. Currently, to protect against this, a protective shell is often placed on the outside of the grinding wheel to prevent burrs and scrap from flying out and injuring people. However, current protective shells often only cover the outside of the grinding wheel with a fixed structure, and play a supplementary role in guiding the flow. This method of grinding protection mainly uses a passive approach to guide the burrs and scrap, but this method cannot effectively collect grinding debris and residue, and the grinding debris can still fly out from the opening side of the protective shell, causing injury to personnel. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-3 This utility model provides an implementation scheme: In the modern workpiece grinding process, the grinding debris generated will be splashed outward at high speed under the action of the grinding roller 4, which can easily cause injury to the worker. However, the current grinding device mainly uses a small protective shell 5 arranged on the outside of the grinding device. This protective shell 5 can only passively guide the debris. Due to the lack of an active guiding device, the debris can easily be sprayed out at the opening of the protective shell 5, causing injury to people.
[0023] To address the above issues, please refer to the appendix to the instruction manual. Figure 1-3 As can be seen, this application discloses a protective grinding device, which uses a grinding operation rod 1 as the main support. A grinding motor 2 is provided at the head end of the grinding operation rod 1, and a rotating seat 3 is provided at the head end of the grinding motor 2. The rotating seat 3 is integrally formed with the front end of the grinding operation rod 1. At the same time, a grinding motor 2 is provided on one side of the rotating seat 3, and a grinding roller 4 is assembled on the other side of the rotating seat 3. The grinding motor 2 is used to drive the grinding roller 4 to rotate, thereby making the grinding roller 4 rotate at high speed, and then making the grinding roller 4 contact the surface of the workpiece, thereby grinding away the burrs and edges on the workpiece. The grinding method used in this application is planar grinding. Furthermore, a protective shell 5 is provided on the rotating seat 3. The protective shell 5 is an open disc-shaped shell. The protective shell 5 is coaxially arranged at one end of the grinding roller 4. The protective shell 5 covers the outer periphery of the grinding roller 4 by its wrapping effect. After the grinding roller 4 grinds away the burrs on the workpiece, the protective shell 5 isolates the debris to prevent it from flying towards the operator.
[0024] Furthermore, to prevent burrs from flying out of the protective shell 5 or from flying out of the opening of the protective shell 5 and causing damage to the surrounding environment and workers, an active suction and diversion device 6 is provided on one side of the protective shell 5.
[0025] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned active suction and flow guiding device 6 includes an active flow guiding port 61, which is connected to one side of the protective shell 5. A flow guiding pipe 62 is connected to one side of the active flow guiding port 61. A flow guiding fan 63 is mounted on the protective shell 5, and the flow guiding fan 63 is connected to the flow guiding pipe 62.
[0026] In the specific implementation process, the active guide port 61 is connected to the inner side of the protective shell 5. The active guide port 61 is set on the radial outer side of the protective shell 5, so that the active guide port 61 can be closer to the guide position of the debris. The guide pipe 62 plays the role of negative pressure transmission. The guide fan 63 set at the tail end of the guide pipe 62 plays the role of negative pressure suction. In the application process, the active guide port 61 is closer to the opening side of the protective shell 5. Under the protective guide effect of the protective shell 5, the debris moves towards the active guide port 61. Under the suction effect of the negative pressure wind, the debris enters the guide pipe 62.
[0027] In order to separate debris from negative pressure air, a filter container 64 is provided in the middle section of the guide pipe 62 between the guide fan 63 and the active guide port 61. The filter container 64 is used to filter out debris, so that negative pressure air passes through the guide fan 63. Then, the two sides of the filter container 64 are connected to the guide pipe 62 through a pair of quick-release components 65. After the debris is separated, the filter container 64 can be removed through the quick-release components 65 to clean up the intercepted debris.
[0028] As a preferred option, the grinding operation lever 1 is further provided with a control switch button 11, and a reinforcing sleeve 12 is fitted on the grinding operation lever 1 to enhance the structural strength of the grinding operation lever 1. The control switch button 11 is used to control the switching on and off of the grinding motor 2.
[0029] As a preferred option, the rotating base 3 is further provided with several fixing holes, and the protective shell 5 is provided with an annular mounting ring at its center, which corresponds to the rotating base 3. The mounting ring is fixed to several fixing holes by several bolts, which facilitates the disassembly and assembly of the protective shell 5.
[0030] As a preferred embodiment, the filter container 64 is further provided with a flow guide net 641 on one side and a pair of connecting rings 642 on both sides of the filter container 64. The flow guide net 641 is a filter net used to filter grinding debris, and the pair of connecting rings 642 are used to connect with the quick-release assembly 65.
[0031] As a preferred embodiment, the quick-release assembly 65 further includes a connecting groove, the middle section of the guide tube 62 is provided with a connecting groove, a pair of mating rings 651 are provided on both sides of the connecting groove, a pair of insertion holes 652 are provided on the mating rings 651, a pair of insertion rods 643 are provided on the connecting rings 642, and the pair of insertion rods 643 are inserted into the pair of insertion holes 652.
[0032] In the specific implementation process, the spacing of the connecting groove is matched with the length of the filter container 64. A pair of docking rings 651 are a pair of semi-circular plates. A pair of connecting rings 642 are matched with a pair of docking rings 651 to form a complete ring structure. Through the arrangement of connecting rings 642 and docking rings 651, the insertion rod 643 is inserted into the insertion hole 652, so that the connecting rings 642 and docking rings 651 are connected.
[0033] As a preferred embodiment, the diameter of the insertion rod 643 matches that of the insertion hole 652. A limiting spring block 653 is provided on the insertion rod 643, and a limiting slot is provided in the insertion hole 652 to match the limiting spring block 653. Furthermore, a limiting spring block 653 is provided at the head end of the insertion rod 643. The limiting spring block 653 and the limiting slot engage with each other to limit the limiting spring block 653, thereby axially limiting the insertion rod 643. Disassembly is convenient by simply pulling out the insertion rod 643.
[0034] In summary, this protective grinding device employs a protective shell 5 on one side of the grinding roller 4 to guide and shield the debris, preventing it from injuring the user. Furthermore, an active suction and guiding device 6 is installed on the protective shell 5 to actively draw and guide the debris, allowing air to carry the debris into the filter container 64. The filter container 64 then separates the debris and cleans it, thus actively collecting the debris and preventing it from splashing and damaging the equipment and personnel.
