Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0022] The grinding equipment for the production of door and window frames according to the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0023] As Figures 1 - 5 shown, the grinding equipment for the production of door and window frames according to the embodiments of the present application may include a grinding table 1, a grinding assembly 2, a lifting and positioning mechanism 3, and a fixing mechanism 4.

[0024] Among them, the grinding assembly 2 may include a support frame 21, a rotating shaft 22, a driving mechanism 23, a reciprocating mechanism 24, a sliding rod 25, a mounting frame 26, a linkage mechanism 27, a rotating rod 28, two telescopic rotation drive mechanisms 29, two movable blocks 211, and two grinding rollers 210.

[0025] Among them, the support frame 21 is slidably arranged on the grinding table 1 through an electric slide table, the rotating shaft 22 is rotatably arranged on the support frame 21, the sliding rod 25 is fixedly arranged on the support frame 21, the driving mechanism 23 is arranged on the support frame 21, and the driving mechanism 23 is connected to the rotating shaft 22. The mounting frame 26 is slidably arranged on the sliding rod 25, and the reciprocating mechanism 24 is respectively connected to the rotating shaft 22 and the mounting frame 26. The rotating rod 28 is rotatably arranged on the top of the mounting frame 26, and the rotating rod 28 is connected to the rotating shaft 22 through the linkage mechanism 27. The two movable blocks 211 are respectively slidably arranged on the mounting frame 26 through a sliding mechanism, and the two grinding rollers 210 are respectively rotatably arranged on the two movable blocks 211. The two grinding rollers 210 are also respectively connected to the rotating rod 28 through the telescopic rotation drive mechanism 29.

[0026] The lifting and positioning mechanism 3 is arranged on the support frame 21, and the lifting and positioning mechanism 3 is located below the two grinding rollers 210. The fixing mechanism 4 is respectively arranged on the lifting and positioning mechanism 3 and the mounting frame 26.

[0027] It should be noted that the support frame 21 described in this embodiment is slidably arranged on the grinding table 1 through an electric slide table (not specifically shown in the figure) to be able to adapt to different door and window frame sizes, so that when grinding door and window frames of different sizes, the position can be adjusted according to the actual size of the door and window frame.

[0028] Specifically, when grinding the inner and outer walls of the door and window frame, the relevant personnel first place the door and window frame body 5 to be ground on the lifting and positioning mechanism 3, and place one side rod of the door and window frame body 5 between the two grinding rollers 210. Then, the relevant personnel drive the two movable blocks 211 through the sliding mechanism to drive the two grinding rollers 210 to move towards each other, so as to position one side rod of the door and window frame body 5 between the two grinding rollers 210, and enable the two grinding rollers 210 to respectively contact the inner wall and the outer wall of one side rod of the door and window frame body 5. Then, the relevant personnel lift the door and window frame body 5 by starting the lifting and positioning mechanism 3 until the door and window frame body 5 can be clamped and fixed between the mounting frame 26 and the lifting and positioning mechanism 3 under the action of the fixing mechanism 4.

[0029] After the door and window frame body 5 is fixed, the relevant personnel then start the driving mechanism 23 to drive the rotating shaft 22 to rotate, so that the rotating shaft 22 can drive the mounting frame 26 to reciprocate on the sliding rod 25 through the reciprocating mechanism 24, so as to realize the simultaneous reciprocating grinding of the inner and outer side walls of the door and window frame body 5 through the mutual cooperation of the mounting frame 26 and the two grinding rollers 210, effectively improving the grinding efficiency of the door and window frame body 5 and reducing manual intervention.

[0030] In addition, while the rotating shaft 22 is rotating, the rotating rod 28 is also driven to rotate through the linkage mechanism 27, so that the rotating rod 28 can drive the two grinding rollers 210 to rotate respectively through the two telescopic driving and rotating mechanisms 29, so as to realize the grinding drive of the two grinding rollers 210 on the door and window frame body 5, thereby effectively reducing the number of driving devices, reducing the production and maintenance costs of the devices, and, under the action of the two telescopic driving and rotating mechanisms 29, enabling the rotating rod 28 to still drive the two grinding rollers 210 after the grinding rollers 210 perform linear sliding motion.

[0031] In an embodiment of the present application, as Figures 1 - 5 shown, the grinding assemblies 2 can be set to four, and the four grinding assemblies 2 are arranged in a rectangular array on the grinding table 1.

[0032] Specifically, since the shape of the door and window frame body 5 is mostly set to be rectangular, by setting the grinding assemblies 2 to four, the simultaneous grinding treatment of the inner and outer walls of the four side rods of the door and window frame body 5 can be realized, further improving the grinding efficiency of the door and window frame body 5.

[0033] In an embodiment of the present application, as Figures 1 - 5 shown, the driving mechanism 23 can include a fixed frame 231 and a motor 232.

[0034] Among them, the motor 232 is fixedly installed on the support frame 21 through the fixing frame 231, and the output shaft of the motor 232 is coaxially connected to the rotating shaft 22 through a coupling.

[0035] Specifically, the relevant personnel start the motor 232 to drive the rotation of the rotating shaft 22 through the motor 232.

[0036] In an embodiment of the present application, as Figures 1 - 5 shown, the reciprocating mechanism 24 may include two inclined plates 241, a connecting rod 242, a connecting shaft 243 and a pivot rod 244.

[0037] Among them, the two inclined plates 241 are respectively fixedly arranged on the rotating shaft 22, the connecting rod 242 is rotatably arranged between the two inclined plates 241, one end of the connecting shaft 243 is fixedly connected to the connecting rod 242, and the other end of the connecting shaft 243 is pivotally connected to one end of the pivot rod 244, and the other end of the pivot rod 244 is pivotally connected to the mounting frame 26.

[0038] It should be noted that the connection between the connecting shaft 243 and the connecting rod 242 described in this embodiment is connected through a universal joint (not specifically marked in the figure).

[0039] Specifically, when the rotating shaft 22 rotates, it also drives the two inclined plates 241 to rotate, and then drives the mounting frame 26 to reciprocate under the action of the connecting shaft 243 and the pivot rod 244, so as to drive the two grinding rollers 210 to reciprocally grind the inner and outer walls of the door and window frame body 5 through the mounting frame 26.

[0040] In an embodiment of the present application, as Figures 1 - 5 shown, the linkage mechanism 27 may include a sleeve 271, a first rotating ring 272, a vertical bevel gear 273, a fixing rod 274, a horizontal bevel gear 275.

[0041] Among them, the sleeve 271 is axially slidably arranged on the rotating shaft 22, the first rotating ring 272 is rotatably sleeved on the sleeve 271, the fixing rod 274 is arranged between the first rotating ring 272 and the mounting frame 26, and both ends of the fixing rod 274 are fixedly connected to the first rotating ring 272 and the mounting frame 26 respectively. The vertical bevel gear 273 and the horizontal bevel gear 275 are respectively sleeved on the sleeve 271 and the rotating rod 28, and the vertical bevel gear 273 is meshed with the horizontal bevel gear 275.

[0042] Specifically, during the rotation of the rotating shaft 22, it also drives the sleeve 271 and the vertical bevel gear 273 to rotate, and then drives the rotating rod 28 to rotate through the horizontal bevel gear 275 meshed with the vertical bevel gear 273. And under the action of the fixing rod 274 and the first rotating ring 272, the sleeve 271 can also follow the mounting frame 26 to reciprocate, so as to always drive the rotating rod 28 to rotate during the rotation of the rotating shaft 22.

[0043] In one embodiment of the present application, as Figures 1 - 5 shown, the sliding mechanism can be set as a rodless cylinder 212. The rodless cylinder 212 is fixedly installed on the mounting frame 26, and the movable block 211 is fixedly arranged on the slider of the rodless cylinder 212.

[0044] Specifically, the relevant personnel drive the movable block 211 to move by starting the rodless cylinder 212, so as to drive the grinding roller 210 to abut against the inner and outer side walls of the door and window frame body 5.

[0045] In one embodiment of the present application, as Figures 1 - 5 shown, the telescopic rotation driving mechanism 29 can include a second rotating ring 291, a fixed tube 292, a sliding tube 293, a first worm 294, a first worm gear 295, a second worm 296, a second worm gear 297, a third rotating ring 298 and a support rod 299.

[0046] Wherein, the second rotating ring 291 is rotatably sleeved on the fixed tube 292, and the second rotating ring 291 is fixedly connected with the mounting frame 26. The sliding tube 293 is axially slidably arranged in the fixed tube 292. The third rotating ring 298 is rotatably sleeved on the sliding tube 293, and the third rotating ring 298 is fixedly connected with the movable block 211 through the support rod 299. The first worm 294 and the first worm gear 295 are respectively sleeved on the rotating rod 28 and the fixed tube 292, and the first worm 294 is meshed with the first worm gear 295. The second worm 296 and the second worm gear 297 are respectively sleeved on the sliding tube 293 and the grinding roller 210, and the second worm 296 is meshed with the second worm gear 297.

[0047] Specifically, during the rotation of the rotating rod 28, the rotating rod 28 also drives the fixed tube 292 to rotate through the meshed first worm 294 and first worm gear 295, and then drives the sliding tube 293 to rotate through the fixed tube 292. During the rotation of the sliding tube 293, the grinding roller 210 is driven to rotate through the meshed second worm 296 and second worm gear 297. And because the sliding tube 293 is axially slidably connected with the fixed tube 292, the third rotating ring 298 is rotatably sleeved on the sliding tube 293, and the third rotating ring 298 is fixedly connected with the movable block 211 through the support rod 299. Therefore, when the movable block 211 moves, it also drives the sliding tube 293 to expand and contract in the fixed tube 292, and the second worm 296 and the second worm gear 297 move synchronously, so that the rotating rod 28 can always drive the grinding roller 210.

[0048] In one embodiment of the present application, as Figures 1 - 5 shown, the lifting and positioning mechanism 3 can include a connecting frame 301, a hydraulic cylinder 302, a positioning plate 303 and a positioning frame 304.

[0049] Among them, the connecting frame 301 is fixedly arranged on the support frame 21, the hydraulic cylinder 302 is fixedly installed on the connecting frame 301, the positioning plate 303 is fixedly arranged on the movable end of the hydraulic cylinder 302, and the positioning frame 304 is fixedly arranged on the positioning plate 303 through bolts.

[0050] It should be noted that the positioning frame 304 described in this embodiment can be adaptively customized according to the size of the door and window frame to be polished, so that when processing door and window frames of different sizes, the positioning frame 304 adapted to the size of the door and window can be correspondingly used.

[0051] Specifically, when positioning the door and window frame body 5, the relevant personnel place the door and window frame body 5 on the positioning frame 304, and make the side rod to be polished be between the two grinding rollers 210, and then drive the two grinding rollers 210 to move closer to each other to abut the side rod between the two grinding rollers 210.

[0052] In an embodiment of the present application, as Figures 1 - 5 shown, the fixing mechanism 4 may include a rubber strip 401, an abutting plate 402 and a plurality of balls 403.

[0054] Specifically, after the positioning and placing of the door and window frame body 5 is completed, the relevant personnel lift the door and window frame body 5 by starting the hydraulic cylinder 302 until it is clamped and fixed between the rubber strip 401 and the plurality of balls 403. The arrangement of the plurality of balls 403 is to reduce the friction between the mounting frame 26 and the door and window frame body 5 during the reciprocating movement.
