Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a grinding device for sheet metal processing. Background Technology

[0002] Sheet metal processing is the process of processing metal sheets into parts or products of the required shape and size. Grinding is an important step in sheet metal processing. For example, a surface grinding device for sheet metal processing mentioned in authorization announcement number CN222537221U includes a worktable, a clamping part, a protective cover and a grinding roller. The top of the worktable is provided with a protective cover, and servo motors are installed on both sides inside the protective cover. A second threaded rod is installed on the output shaft end of the servo motor.

[0003] However, existing technologies still have the following problems:

[0004] Firstly, the device can clamp and limit the sheet metal before grinding and dust removal. However, in actual use, picking up and placing the sheet metal is very time-consuming and laborious, requiring operators to bend over and push to pick up and place the sheet metal, which is not user-friendly.

[0005] Secondly, after the sheet metal is polished, the friction generates a lot of heat, which can easily burn the operator when the sheet metal is removed. It is also difficult to cool it down easily. In addition, after the sheet metal is polished, there will still be debris left on the surface, which is difficult to clean easily, which is not conducive to its widespread use.

[0006] To address the aforementioned problems, the inventors have proposed a grinding device for sheet metal processing. Utility Model Content

[0007] To address the problems of inconvenient handling of sheet metal, difficulty in convenient cooling after grinding, and difficulty in cleaning residual debris on the sheet metal surface, this utility model aims to provide a grinding device for sheet metal processing.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a grinding device for sheet metal processing, including a base plate, a grinding box fixedly connected to the top surface of the base plate, a moving plate provided in the inner cavity of the grinding box, a clamping mechanism provided on the top surface of the moving plate, a guiding mechanism provided on one side surface of the grinding box, a support base fixedly connected to the top surface of the grinding box, and a cooling mechanism provided on one side of the grinding box.

[0009] Preferably, the guiding mechanism includes a guide box, one end of which is fixedly connected to a servo motor, and the inner cavity of the guide box is provided with a lead screw body. One end of the lead screw body is fixedly connected to the output end of the servo motor, and the end of the lead screw body away from the servo motor is movably connected to the guide box through a bearing.

[0010] Preferably, the cooling mechanism includes a water tank located on one side of the grinding box. A water pump is fixedly connected to the top surface of the water tank. A spray pipe is fixedly connected to the outlet end of the water pump. A lifting plate is fixedly connected to the top surface of the spray pipe. A protruding plate is fixedly connected to the bottom surface of the lifting plate. A wiping layer is movably connected to the bottom surface of the protruding plate by Velcro. A lifting electric push rod is fixedly connected to the top surface of the lifting plate. The outer surface of the sleeve end of the lifting electric push rod is fitted and fixedly connected to the support base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting up a motion plate and a guide mechanism, the motion plate assembly can be extended or retracted from the grinding box with ease and convenience, which is more user-friendly for operators to pick up and put away sheet metal. The servo motor drives the rotation of the lead screw to extend or retract the motion plate in the grinding box, and the locking strip improves the stability of the motion plate movement.

[0013] 2. By setting up a cooling mechanism, when the polished sheet metal extends out of the polishing box, the surface of the polished sheet metal can be conveniently sprayed with water to cool it down, avoiding burns to the operator caused by the heat generated by friction. In addition, the wiping layer wipes the sheet metal surface, which not only removes the sprayed water mist, but also better cleans the residual debris on the sheet metal surface, making it more practical.

[0022] 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.

[0023] Example: Figure 1-6As shown, this utility model provides a grinding device for sheet metal processing, including a base plate 1. A grinding box 2 is fixedly connected to the top surface of the base plate 1. A first linear guide rail 8 is fixedly connected to the top surface of the grinding box 2. A second linear guide rail 9 is provided below the first linear guide rail 8. The first linear guide rail 8 and the second linear guide rail 9 are common and well-known linear guide rail devices. A locking slider is fixedly connected to the top surface of the second linear guide rail 9 and the top surface of the upper and lower electric push rods 10. The locking slider matches the structural dimensions of the two linear guide rails. Under the action of the first linear guide rail 8, the second linear guide rail 9 and the grinding machine 11 assembly move left and right. Under the action of the second linear guide rail 9, the grinding machine 11 assembly moves back and forth, thereby enabling the grinding machine 11 to better perform grinding operations on the sheet metal. This is a common technical method and will not be described in detail. Below the second linear guide rail 9, there is an upper and lower electric push rod 10. The extension end of the upper and lower electric push rod 10 is fixedly connected to a grinder 11. The outer surface of the grinder 11 is fixedly connected to a dust collection box 12 through a connecting plate. The top surface of the base plate 1 is fixedly connected to a dust collection box 13. A filter box 14 is fixedly connected to one side of the dust collection box 13. A vacuum cleaner 15 is fixedly connected to one side of the filter box 14. The dust outlet end of the dust collection box 12 is fixedly connected to the dust collection box 13 through a steel wire hose. The extension and retraction of the upper and lower electric push rod 10 causes the grinder 11 to fall. During the grinding process, the vacuum cleaner 15 is started. At this time, the dust generated by grinding enters the dust collection box 13 through the dust collection box 12. The filter screen inside the filter box 14 prevents the dust from damaging the vacuum cleaner 15.

[0024] The inner cavity of the grinding box 2 is provided with a moving plate 3. The top surface of the moving plate 3 is provided with a clamping mechanism 4. The clamping mechanism 4 includes a device box 41 that is fixedly connected to the top surface of the moving plate 3. One end of the device box 41 is fixedly connected to a forward and reverse reduction motor 42. The inner cavity of the device box 41 is provided with a threaded rod 43. One end of the threaded rod 43 is fixedly connected to the output end of the forward and reverse reduction motor 42. The top surface of the device box 41 is fitted and slidably connected with a clamping plate 44. The outer surface of the threaded rod 43 has threads in opposite directions. The bottom ends of the two clamping plates 44 are fixedly connected with sliding blocks 45. The sliding blocks 45 are threadedly connected to the outer surface of the threaded rod 43. The forward and reverse reduction motor 42 drives the rotation of the threaded rod 43, so that the two sliding blocks 45 and the clamping plate 44 assembly move relative to or away from each other. The length of the moving plate 3 plus the length of the forward and reverse reduction motor 42 is less than the width of the inner cavity of the grinding box 2, so as not to hinder the closing of the magnetic sealing door on the front surface of the grinding box 2.

[0025] A guide mechanism 5 is provided on one side surface of the grinding box 2. The guide mechanism 5 includes a guide box 51. A servo motor 52 is fixedly connected to one end of the guide box 51. A lead screw body 53 is provided in the inner cavity of the guide box 51. One end of the lead screw body 53 is fixedly connected to the output end of the servo motor 52. The end of the lead screw body 53 away from the servo motor 52 is movably connected to the guide box 51 through a bearing. A sleeve block 54 is fixedly connected to one side surface of the motion plate 3. The sleeve block 54 is threadedly connected to the outer surface of the lead screw body 53. A locking strip 55 is fixedly connected to the bottom surface of the motion plate 3. A slot matching the structural size of the locking strip 55 is opened on the bottom surface of the inner cavity of the grinding box 2. When the servo motor 52 is started, it drives the lead screw body 53 to rotate, thereby causing the sleeve block 54 and the motion plate 3 assembly to move, extending or retracting the motion plate 3 from the grinding box 2. The locking strip 55 slides on the bottom surface of the grinding box 2 to improve the stability of the motion plate 3.

[0026] A support base 6 is fixedly connected to the top surface of the grinding box 2. A cooling mechanism 7 is provided on one side of the grinding box 2. The cooling mechanism 7 includes a water tank 71 located on one side of the grinding box 2. A water pump 72 is fixedly connected to the top surface of the water tank 71. A spray pipe 73 is fixedly connected to the outlet end of the water pump 72. A lifting plate 74 is fixedly connected to the top surface of the spray pipe 73. A protruding plate 75 is fixedly connected to the bottom surface of the lifting plate 74. A wiping layer 76 is movably connected to the bottom surface of the protruding plate 75 by Velcro. A lifting electric push rod 77 is fixedly connected to the top surface of the lifting plate 74. The outer surface of the sleeve end of the lifting electric push rod 77 is fitted and fixedly connected to the support base 6. When the water pump 72 is started, water in the water tank 71 is drawn into the spray pipe 73 and sprayed out through the spray head of the spray pipe 73. The extension and retraction of the lifting electric push rod 77 drives the lifting plate 74 assembly to move up and down. The wiping layer 76 performs wiping and cleaning operations on the sheet metal surface. The wiping layer 76 is made of common cotton material.

[0027] It should be noted that, with the assistance of those skilled in the art, all electrical components in this case, such as the forward and reverse geared motor 42, servo motor 52, water pump 72, lifting electric push rod 77, and up and down electric push rod 10, should be connected to the vacuum cleaner 15 and their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0028] Working principle: When in use, first place the base plate 1 in a suitable position, then open the magnetic sealing door on the front side of the grinding box 2. At this time, control the start of the servo motor 52 to drive the rotation of the lead screw 53, so that the moving plate 3 and the sleeve block 54 assembly move. The moving plate 3 gradually extends out of the grinding box 2, and the locking strip 55 at the bottom of the moving plate 3 slides at the bottom of the inner cavity of the grinding box 2 to improve stability.

[0029] After the motion plate 3 is fully extended, the sheet metal is placed on the top surface of the motion plate 3. The start of the forward and reverse reduction motor 42 is controlled to drive the rotation of the threaded rod 43. At this time, the two sets of clamping plates 44 and sliding block 45 assemblies move relative to each other to clamp and limit the sheet metal.

[0030] The servo motor 52 is controlled to rotate in the opposite direction, and the motion plate 3 is retracted into the grinding box 2. The first linear guide rail 8, the second linear guide rail 9, the upper and lower electric push rods 10 and the grinding machine 11 are controlled to start, and the sheet metal is ground. The dust and debris generated during grinding are sucked into the dust collection box 13 by the vacuum cleaner 15.

[0031] After grinding is completed, the servo motor 52 is started to extend the motion plate 3 out of the grinding box 2. At this time, the extension of the lifting electric push rod 77 is controlled to lower the lifting plate 74, and the wiping layer 76 contacts the top surface of the sheet metal. The water pump 72 is started to pump the water in the water tank 71 into the spray pipe 73 and spray it out. At this time, as the motion plate 3 gradually extends, the spray pipe 73 sprays the sheet metal surface to cool it down, and the wiping layer 76 wipes and cleans the water droplets and residual debris on the sheet metal surface.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
