[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] Embodiment 1

[0041] like Figure 1-Figure 10 As shown, a copper door burr grinding device proposed in the first embodiment of the present application includes:

[0042] A mounting frame 1 is provided with a grinding member 2, the grinding member 2 comprising a driving motor 201 mounted on the mounting frame 1, a bidirectional screw rod 202 is mounted on the output shaft of the driving motor 201, the bidirectional screw rod 202 is rotationally matched with the mounting frame 1, a grinding portion is meshed on the bidirectional screw rod 202, the grinding portion is used to grind the side wall of the copper door, when in use, the mounting frame 1 is used to carry other components on the device, the grinding portion is slidably matched with the mounting frame 1, when in use, the grinding portion is driven by the driving motor 201 and the bidirectional screw rod 202, so that it slides back and forth on the mounting frame 1, so that the grinding portion can grind the side wall of the copper door and perform a deburring operation on the copper door;

[0043] The fixing member 3 is installed on the mounting frame 1. The fixing member 3 includes a bearing part and a pressing part. The pressing part is slidably connected to the mounting frame 1, and the bearing part is fixedly connected to the mounting frame 1. The bearing part is used to bear the copper door, and the pressing part is used to press the copper door. When in use, the copper door is first placed on the bearing part, and then clamped and fixed by the pressing of the pressing member, which reduces the possibility of misoperation during grinding, resulting in poor grinding effect;

[0044] The fixing member 3 further includes a locking portion, which is connected to the holding portion, and the locking portion is connected to the bidirectional screw rod 202. When the bidirectional screw rod 202 rotates, that is, it is in the grinding state, the locking portion restricts the sliding of the holding portion on the mounting frame 1, thereby increasing the stability of the holding portion when in use, and further increasing the stability of the copper door when being ground;

[0045] The cleaning member 4 is installed on the mounting frame 1. The cleaning member 4 includes a cleaning plate 401. The cleaning plate 401 is slidably matched with the mounting frame 1. The cleaning plate 401 is slidably connected to the grinding part. There are two cleaning plates 401, which are respectively located on both sides of the grinding part. One side of the cleaning plate 401 is provided with textures to increase the contact area between the cleaning plate 401 and the copper door, thereby increasing the cleaning effect. The cleaning plate 401 is made of plastic, which reduces the possibility of causing wear to the copper door when scraping the copper door. When the grinding part reciprocates on the mounting frame 1, it also drives the cleaning plate 401 to slide back and forth on the mounting frame 1, so that the cleaning plate 401 scrapes and cleans the side of the copper door. The cleaning plates 401 are located on both sides of the grinding part, and one of them will definitely clean the part of the copper door that has just been polished.

[0046] The cleaning plate 401 is in contact with the fixing member 3. When the polishing part polishes the copper door, the fixing member 3 causes the cleaning plate 401 to scrape on the side wall of the copper door. Figure 1From the main perspective, the sliding direction between the cleaning plate 401 and the grinding part is along the vertical direction. When it moves with the grinding part, the sliding direction between it and the mounting frame 1 is along the horizontal direction. When in use, the cleaning plate 401 scrapes the copper door along the horizontal direction with the grinding part, and also slides in the vertical direction through the cooperation of the fixing member 3, thereby increasing its cleaning effect on the copper door and further reducing the possibility of grinding debris adhering to the copper door.

[0047] Compared with the prior art, the grinding part is driven by the driving motor 201 and the bidirectional screw 202 on the mounting frame 1, so that the grinding part can perform more comprehensive grinding on the side wall of the copper door, and in the process, the copper door is fixed by the fixing part 3, and when grinding, the bidirectional screw 202 must rotate, and the holding part keeps the copper door fixed through the cooperation of the locking part of the fixing part 3, and when grinding the copper door, the cleaning plate 401 is used to scrape and clean the side wall of the copper door after grinding, which reduces the possibility of burrs and debris adhering to the side of the copper door during grinding, resulting in poor grinding effect, and increases the practicality of the device.

[0048] Embodiment 2

[0049] like Figure 5 and Figure 7 As shown, the second embodiment discloses the grinding member 2, the fixing member 3 and the cleaning member 4 on the basis of the first embodiment. In the second embodiment, the grinding member 2 includes:

[0050] The slider 203 is meshed with the bidirectional screw rod 202. A mounting plate 204 is mounted on the slider 203. A fixed gear 205 is mounted on the mounting plate 204. The slider 203 is T-shaped. Figure 1 From the main perspective, the horizontal section is engaged with the bidirectional screw rod 202, and the vertical section is connected to the cleaning plate 401. The mounting plate 204 is located at the bottom of the slider 203, making it closer to the copper door. A round hole is opened on the mounting plate 204, such as Figure 5 As shown, the fixed gear 205 is fixedly connected to the mounting plate 204;

[0051] The rotating rod 206 has one end rotatably mounted on the fixed gear 205, and the other end is mounted with a driving gear 2011. The mounting frame 1 is mounted with a rack 2012 meshing with the driving gear 2011. The axis of the rotating rod 206 is colinear with the axis of the fixed gear 205. When in use, when the slider 203 slides on the mounting frame 1, the driving gear 2011 and the rack 2012 move relative to each other, so that the driving gear 2011 drives the rotating rod 206 to rotate on the fixed gear 205;

[0052] A side rod 207 is installed on the rotating rod 206, and a secondary rod 208 is rotatably installed on the side rod 207. A grinding plate 209 is installed on one end of the secondary rod 208, and a transmission gear 2010 is installed on the other end. The transmission gear 2010 is meshed with the fixed gear 205. The rotating rod 206 slides with the inner wall of the circular hole of the mounting plate 204. When the rotating rod 206 rotates, the connecting end of the side rod 207 and the secondary rod 208 makes a circular motion around the rotating rod 206, and the end of the secondary rod 208 is installed with a transmission gear 2010 meshed with the fixed gear 205. The meshing of the transmission gear 2010 and the fixed gear 205 makes the transmission gear 2010 rotate when it rotates around it, so that the auxiliary rod 208 also rotates, forming a structure similar to a planetary gear, so that the grinding plate 209 not only rotates but also makes a circular motion around the rotating rod 206. The side of the grinding plate 209 close to the fixing member 3 can be fixed with sandpaper by bolts or glue, etc. The rough edges of the copper door side are polished by the rotation and revolution of the grinding plate 209, wherein the slider 203 and the grinding plate 209 constitute a grinding part;

[0053] When the grinding plate 209 is grinding, it not only rotates on itself and revolves around the rotating rod 206, but also as the slider 203 moves linearly on the mounting frame 1, the movement path of the grinding plate 209 on the side wall of the copper door is increased, and the grinding area at the same time is increased, thereby improving the grinding effect and grinding efficiency of the device.

[0054] like Figure 2 , Figure 6 , Fig. 9 and Fig.10 As shown, in the second embodiment, the fixing member 3 includes:

[0055] The bearing plate 3013 is installed on the mounting frame 1. The bearing plate 3013 is used to bear the copper door. The bearing plate 3013 is a bearing part.

[0056] The sliding plate 301 is mounted on the mounting frame 1, and a holding plate 302 is slidably mounted on the sliding plate 301. The holding plate 302 is a holding portion. A pressing rod 303 is hinged on the mounting frame 1. A sliding groove 304 is provided on the pressing rod 303. A sliding rod 305 that slides with the sliding groove 304 is installed on the pressing plate 302. When the pressing rod 303 rotates, the holding plate 302 approaches or moves away from the bearing plate 3013. The rod body of the pressing rod 303 is hinged on the mounting frame 1. The rod body diameter of the sliding rod 305 is less than or equal to the notch width of the sliding groove 304, and the sliding rod 305 moves away from the pressing plate 3 A plate body is installed on one end of 02, and the diameter of the plate body is larger than the slot width of the sliding slot 304. When the end of the pressing rod 303 with the sliding slot 304 rotates away from the bearing plate 3013, it pulls the sliding rod 305 to pull the holding plate 302 away from the bearing plate 3013, which makes it easy to place the copper door between the bearing plate 3013 and the holding plate 302. When the end rotates close to the bearing plate 3013, the pressing rod 303 cooperates with gravity to make the holding plate 302 close to the bearing plate 3013, so that the holding plate 302 presses the copper door and fixes it.

[0057] The pad 306 is slidably mounted on the mounting frame 1. A plate body is mounted on both sides of the pad 306 on the mounting frame 1. A limiting groove 21 is provided on the plate body. Both sides of the pad 306 are constructed with protrusions that slide with the limiting groove 21. The limiting groove 21 limits the protrusions on the inner wall of the limiting groove 21, so that the pad 306 can only approach or move away from the pressing rod 303 in a straight line direction. The rotation direction of the pressing rod 303 is defined. When the pressing plate 302 is pressed and moved toward the bearing plate 3013, the direction is set as the first direction. When the pressing plate 302 is pulled away from the bearing plate 3013, the direction is set as the second direction. The pressing rod 303 is in a Z shape. When the pressing rod 30 When the pressing plate 302 is pressed, the middle section thereof is in the vertical direction, and the other two sections are in the horizontal direction. When the pad 306 contacts the pressing rod 303, the side wall of the pad 306 abuts against the side wall of the middle section of the pressing rod 303, and the horizontal section of the pressing rod 303 is supported by the pad 306, thereby limiting the rotation of the pressing rod 303. The pad 306 abuts against the pressing rod 303, thereby blocking the path of the pressing rod 303 rotating in the second direction, thereby preventing the pressing rod 303 from rotating in the second direction, thereby increasing the stability of the pressing rod 303 when in use. The pad 306 and the pressing rod 303 are locking parts.

[0058] A pulley 308 is mounted on the pad 306 through a connecting spring 307. The cross-section of the pulley 308 is H-shaped, and the width of the middle part of the pulley 308 is greater than the thickness of a single spiral of the spiral plate 309. The spiral plate 309 is rotatably mounted on the mounting frame 1. The pulley 308 and the spiral plate 309 are in rolling cooperation. The diameter of the spiral plate 309 gradually decreases from one end close to the pressing rod 303 to the other end. A circular plate 22 is mounted at the spiral with the largest diameter of the spiral plate 309. The sum of the thickness of the circular plate 22 and a single spiral is also less than the length of the middle section of the pulley 308. The mounting frame 1 A driving rod 3010 is rotatably installed on the upper part, and the driving rod 3010 is connected to the bidirectional screw rod 202 through a pulley assembly 3011, and the driving rod 3010 is connected to the rotating shaft of the spiral plate 309 through a bevel gear pair 3012. The pulley assembly 3011 includes a pulley and a belt. The pulley has two bevel gears connected to the bidirectional screw rod 202 and the driving rod 3010 respectively. The belt is used to connect the two pulleys. The bevel gear pair 3012 includes two bevel gears with perpendicular axes, one of which is connected to the driving rod 3010, and the other is located on the rotating shaft of the spiral plate 309.

[0059] The initial position of the pulley 308 on the spiral plate 309 is at the spiral part with the smallest diameter. The pulley 308 is slidably connected with the pad 306 through the rod body. When the grinding piece 2 is working, the bidirectional screw 202 rotates, and the driving rod 3010 is driven to rotate through the pulley assembly 3011, and then the spiral plate 309 is driven to rotate through the bevel gear pair 3012, so that the pulley 308 slides on it, gradually approaches the pressing rod 303, and the pulley 308 moves in the direction close to the pad 306 as the diameter of the spiral plate 309 gradually increases. At this time, the connecting spring 307 is compressed. When it moves When the spiral plate 309 moves to the maximum diameter, the connecting spring 307 is in a compressed state, which contacts the pad 306, thereby reducing the gap between the pad 306 and the pressing rod 303, thereby reducing the possibility that the pad 306 shakes during use and causes unstable limiting of the pressing rod 303. At this time, the pulley 308 also keeps rolling with the spiral plate 309 at the maximum diameter of the circular plate 22 and the spiral plate 309. Through the contact of the connecting spring 307 and the unidirectional rotation of the spiral plate 309, the pad 306 remains stable when limiting the pressing rod 303, thereby increasing the practicality of the device.

[0060] When in use, first rotate the pressing rod 303 to make the holding plate 302 move away from the supporting plate 3013, place the copper door between the two, and then rotate the pressing rod 303 to make the holding plate 302 hold the copper door, and then start the device to make the bidirectional screw rod 202 drive the spiral plate 309 to rotate, and the pad 306 moves to contact the pressing rod 303 through the rolling of the pulley 308, and limits its tendency to rotate in the second direction. When the grinding is completed, pulley 308 is pulled, and the pulley 308 is separated from the spiral plate 309 through the elastic deformation of the connecting spring 307, and the pad 306 is pulled to slide to the initial position. At this time, rotate the pressing rod 303 to release the holding plate 302 from the copper door to unload the material.

[0061] like Figure 7 and Figure 8 As shown, in the second embodiment, the cleaning member 4 includes:

[0062] A fixed plate 402 is mounted on the slider 203. There are two fixed plates 402, which are located on both sides of the slider 203. A movable plate 404 is installed on the fixed plate 402 by pulling a spring 403. The movable plate 404 is connected to the cleaning plate 401. A resisting rod 406 is installed on the movable plate 404. A plurality of arc plates 407 are installed on the mounting frame 1. The driving rod 3010 is rotatably mounted on the arc plate 407. When the resisting rod 406 resists the arc plate 407, the movable plate 404 moves away from the fixed plate 402. When in use, when the slider 203 reciprocates on the mounting frame 1, the fixed plate 402 is also driven to reciprocate on the mounting frame 1 at the same time and speed as the slider 203. There are a plurality of arc plates 407, which are linearly arrayed on the mounting frame 1 along the sliding direction of the slider 203. The arc plates 407 have the following features: The following functions are: first, it is used to install the driving rod 3010 and provide an installation position for the driving rod 3010; second, when the fixed plate 402 moves, the abutment rod 406 also moves with it; when the abutment rod 406 moves to abut against the arc plate 407, the arc plate 407 pushes it away from the fixed plate 402, thereby making the movable plate 404 and the cleaning plate 401 away from the fixed plate 402; when the abutment rod 406 and the arc plate 407 are no longer in conflict, the pulling spring 403 pulls the movable plate 404 and the cleaning plate 401 to reset, so that when the fixed plate 402 reciprocates in the horizontal direction on the mounting frame 1, the cleaning plate 401 not only reciprocates in the horizontal direction, but also reciprocates in the vertical direction, so that it cleans the side of the copper door from two directions, thereby increasing the cleaning effect;

[0063] The friction plate 405 is installed on the fixed plate 402. The friction plate 405 contacts the side of the cleaning plate 401 away from the supporting plate 3013. When the cleaning plate 401 reciprocates in the vertical direction, the friction plate 405 remains stationary, blocking the tendency of the cleaning plate 401 to move away from the copper door, thereby increasing the fit between the cleaning plate 401 and the copper door and the cleaning effect on the copper door. The friction between the friction plate 405 and the cleaning plate 401 reduces the sliding speed of the cleaning plate 401, making the cleaning plate 401 more stable when sliding.

[0064] Embodiment 3

[0065] like Figure 1-Figure 10 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a cavity is opened on the fixed plate 402 and the movable plate 404, and the cavity is composed of an upper cavity 5, a middle cavity 6 and a lower cavity 7 which are interconnected. The upper cavity 5 has the same diameter as the lower cavity 7, and the diameter of the middle cavity 6 is smaller than that of the lower cavity 7. A connecting plate 9 is installed in the lower cavity 7, and an extrusion rod 11 is installed on the connecting plate 9 through a push spring 10. The rod diameter of the extrusion rod 11 is larger than the diameter of the middle cavity 6 and smaller than the diameter of the lower cavity 7. A rod body is provided on the connecting plate 9 to slide through the extrusion rod 11 for extruding The sliding direction of the rod 11 is limited, and the inner walls of the upper cavity 5, the middle cavity 6 and the lower cavity 7 are all rounded. The extrusion rod 11 is made of rubber. When in use, the extrusion rod 11 is slid to make it slide back and forth in the upper cavity 5, the middle cavity 6 and the lower cavity 7. When it passes through the middle cavity 6, it will resist the inner wall of the middle cavity 6 and then undergo elastic deformation. When it resists, the movable plate 404 and the fixed plate 402 vibrate, and the debris attached to the cleaning plate 401 is vibrated to remove the debris attached to the cleaning plate 401, thereby reducing the possibility that the debris attached to the cleaning plate 401 will adhere to the copper door again;

[0066] A pressure plate 12 is installed on the extrusion rod 11, and a cam 13 for contacting the pressure plate 12 is installed on the driving rod 3010. When the cam 13 rotates to contact the pressure plate 12, the pressure plate 12 is pressed downward, so that the extrusion rod 11 moves from the upper cavity 5 to the lower cavity 7, generating vibration. When the cam 13 is no longer in contact with the pressure plate 12, the extrusion rod 11 is pushed back by the push spring 10, which will generate vibration again, further reducing the possibility of debris adhering to the cleaning plate 401. The cam 13 is located on the driving rod 3010 near the end of the rod body, and the length of the mounting frame 1 is greater than the length of the copper door. When the cleaning plate 401 moves to the two ends of the driving rod 3010, the cleaning plate 401 does not contact the copper door. The vibration generated at this time will not affect the copper door, reducing the possibility of the copper door position deviation.

[0067] In the third embodiment, the bearing plate 3013 is rotatably mounted with an L-shaped plate 14 at two corners away from the rack 2012. The height of the upper surface of the L-shaped plate 14 is higher than the height of the upper surface of the bearing plate 3013. The L-shaped plate 14 is used to limit the position of the copper door on the bearing plate 3013. An arc groove 15 is provided on the L-shaped plate 14. The corners of the bearing plate 3013 are all rounded. The L-shaped plate 14 is used to contact the side wall of the copper door, which increases the contact area between the bearing plate 3013 and the copper door, and increases the fixing effect of the device on the copper door. As a result, the direction of the supporting plate 3013 toward the polishing piece 2 is set as the working direction. When the device polishes the copper door in the length direction, the L-shaped plate 14 is located on the opposite side of the working direction to restrict the copper door. When the device polishes the copper door in the width direction, the L-shaped plate 14 is rotated to both sides of the working direction to continue to restrict the copper door. The guidance of the arc surface between the arc groove 15 and the fillet facilitates the rotation of the L-shaped plate 14. The restriction of the copper door by the L-shaped plate 14 increases the fixing effect of the device on the copper door.

[0068] In embodiment three, a side plate 16 is installed on the sliding plate 301, and a holding spring 17 is installed between the side plate 16 and the holding plate 302. When the holding plate 302 holds the copper door, the holding spring 17 is stretched. The reverse pulling of the holding spring 17 reduces the gap between the holding plate 302 and the sliding plate 301, thereby increasing the stability of the holding plate 302 during holding.

[0069] In embodiment three, a guide rod 18 is installed on the movable plate 404, a guide hole 19 for accommodating the guide rod 18 is opened on the fixed plate 402, and the pulling spring 403 is sleeved on the outside of the guide rod 18, and the inner wall of the guide hole 19 restricts the side wall of the guide rod 18. Firstly, the sliding direction of the movable plate 404 is restricted by the guide rod 18, thereby increasing the stability of the movable plate 404 during sliding. Secondly, the pulling spring 403 is sleeved on the outside of the guide rod 18, and the deformation direction of the pulling spring 403 is restricted by the guide rod 18, thereby increasing the stability of the pulling spring 403 during deformation.

[0070] In embodiment three, an annular groove 20 is provided on the mounting plate 204, and a ring block 8 is installed on the secondary rod 208, which slides with the annular groove 20. The secondary rod 208 increases the contact area between the secondary rod 208 and the mounting plate 204 through the sliding fit between the ring block 8 and the annular groove 20, thereby increasing the stability of the secondary rod 208 when moving on the mounting plate 204.

[0071] In embodiment three, the distance from the end of the pressing rod 303 that contacts the holding plate 302 to the hinge point between the pressing rod 303 and the mounting frame 1 is less than one-third of the length of the entire pressing rod 303. The pressing rod 303 is a labor-saving lever. When the copper door needs to be loaded or unloaded, the operator can turn the pressing rod 303 with less effort, thereby increasing the practicality of the device.
