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.

[0016] Please see Figure 1-3 This embodiment of a door and window frame grinding device includes a frame 1 and a grinding table 2 rotatably mounted on the frame 1. A box 3 is provided on the rear side of the frame 1 and extends above the grinding table 2. The grinding table 2 is provided with at least four grinding holes 4, which are arranged in a circular array on the grinding table 2. Multiple positioning blocks 5 are provided on the grinding table 2. The box 3 is provided with a drive mechanism 6, a pressing mechanism 8, and two sets of grinding mechanisms 7. The two sets of grinding mechanisms 7 are located on the upper and lower sides of the grinding table 2, respectively. The drive mechanism 6 is used to drive the two sets of grinding mechanisms 7 to move relative to each other or away from each other. The pressing mechanism 8 is used to press and fix the door and window frame onto the grinding table 2.

[0017] In this embodiment, the drive mechanism 6 includes a servo motor 61, a double-ended screw 62, a threaded slider 63, a limiting groove 64, and a limiting block 65. The servo motor 61 is provided on the housing 3, and the output end of the servo motor 61 extends into the housing 3. The output end of the servo motor 61 is provided with a double-ended screw 62, one end of which is rotatably connected to the inner wall of the housing 3. The double-ended screw 62 is composed of two threaded rods with opposite thread directions. The threaded slider 63 is threadedly assembled on the double-ended screw 62. The grinding mechanism 7 is provided on the threaded slider 63. The inner wall of the housing 3 is symmetrically provided with limiting grooves 64. The limiting block 65 is slidably installed in the limiting groove 64. The limiting block 65 is fixedly connected to the threaded slider 63. The grinding mechanism 7 includes a mounting plate 71, a drive motor 72, and a grinding disc 73. The mounting plate 71 is provided on the threaded slider 63, the drive motor 72 is embedded in the mounting plate 71, and the grinding disc 73 is provided at the output end of the drive motor 72.

[0018] Specifically, the servo motor 61 is turned on to drive the double-headed screw 62 to rotate. The double-headed screw 62 drives the threaded sliders 63 on both sides to move relative to each other. The threaded sliders 63 bring the grinding discs 73 on the upper and lower sides closer to the frame. The drive motor 72 is started to drive the grinding discs 73 to rotate at high speed to perform synchronous grinding operations on the upper and lower sides of the frame welding joint.

[0019] In this embodiment, the pressing mechanism 8 includes a mounting frame 81, an electric push rod 82, and a pressing block 83. The mounting frame 81 is symmetrically arranged at the upper end of the housing 3. The mounting frame 81 extends above the grinding table 2. The electric push rod 82 is embedded in the mounting frame 81, and the pressing block 83 is provided at the output end of the electric push rod 82.

[0020] Specifically, the electric push rods 82 on both sides move downwards with the pressing blocks 83 to fit tightly against the frame, positioning the frame in the vertical direction. Combined with the positioning block 5, the frame can be positioned in the horizontal direction, thus firmly fixing the frame on the grinding table 2.

[0021] In this embodiment, the pressing block 83 is a rubber block.

[0022] Specifically, the rubber block can increase the coefficient of friction between the pressing block 83 and the frame, making the frame more securely fixed.

[0023] In this embodiment, at least four guide wheels 11 are provided on the top of the frame 1. The four guide wheels 11 are distributed in a circular array on the frame 1. A reduction motor 12 is provided on the frame 1. The output end of the reduction motor 12 passes through the frame 1 and is fixedly connected to the bottom end of the grinding table 2.

[0024] Specifically, the geared motor 12 is started to rotate the grinding table 2, so that the four corners of the frame move to the grinding station in sequence; the guide wheel 11 can provide additional support for the grinding table 2, making the rotation of the grinding table 2 more stable.

[0025] The working principle of the above embodiments is as follows: (1) Place the frame to be polished in the positioning block 5, and at the same time operate the electric push rods 82 on both sides to move the pressing block 83 downward to fit tightly against the frame. Position the frame in the vertical direction. Combined with the positioning block 5, the frame can be positioned in the horizontal direction. In this way, the frame can be firmly fixed on the polishing table 2. (2) Turn on the servo motor 61 to drive the double-headed screw 62 to rotate. The double-headed screw 62 drives the threaded sliders 63 on both sides to move relative to each other. The threaded sliders 63 bring the grinding discs 73 on the upper and lower sides close to the frame. Start the drive motor 72 to drive the grinding discs 73 to rotate at high speed and perform synchronous grinding operations on the upper and lower sides of the frame welding joint. (3) After the grinding of the front corner of the frame is completed, operate the electric push rod 82 to reset, start the reduction motor 12 to rotate the grinding table 2, so that the four corners of the frame move to the grinding station in turn. Repeat steps (1) and (2) until the four corners of the frame are all ground, and the grinding of the frame is completed.
