[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 In this embodiment, an automatic calibration device for an intelligent CNC guide rail forming grinder includes a grinding table 1, on which a calibration mechanism 2 for calibrating the grinding position of a workpiece is provided, so as to improve the grinding accuracy of the workpiece and speed up the forming speed of the workpiece by the grinder. A fixing mechanism 3 for fixing the workpiece is provided on the grinding table 1, so as to improve the stability of the workpiece so as to grind the workpiece at multiple angles. A bracket 4 is fixed to the lower surface of the grinding table 1.

[0024] There are four brackets 4, which are evenly distributed at the four corners of the lower surface of the grinding table 1, so that the grinding machine remains stable during operation.

[0025] See also Figure 2-3 In order to improve the grinding accuracy of the workpiece and speed up the speed of the grinder to shape the workpiece, the calibration mechanism 2 in this embodiment includes a first motor 201, which is fixed to the right side of the grinding table 1. The output shaft of the first motor 201 penetrates and extends into the interior of the grinding table 1 and is fixed with a first threaded rod 202. The output shaft of the first motor 201 drives the first threaded rod 202 to rotate. The other end of the first threaded rod 202 is rotatably connected to the left inner wall of the grinding table 1 through a bearing. The outer side of the first threaded rod 202 is threadedly connected with a first threaded block 203. The first threaded rod 202 drives the first threaded block 203 to move so as to drive the grinding piece to move left and right. A sliding rod 204 is fixed between the inner walls of the left and right sides of the grinding table 1. The outer side of the sliding rod 204 is slidably connected to the inner side of the first threaded block 203. The sliding rod 204 can limit the angle of the first threaded block 203. To prevent the first threaded block 203 from rotating, a mounting plate 205 is fixed to the upper surface of the first threaded block 203, and a second motor 206 is fixed to the upper surface of the mounting plate 205. The output shaft of the second motor 206 penetrates and extends to the inside of the mounting plate 205, and a second threaded rod 207 is fixed thereto. The output shaft of the second motor 206 drives the second threaded rod 207 to rotate, and the outer side of the second threaded rod 207 is threadedly connected with a second threaded block 208, and the second threaded rod 207 drives the second threaded block 208 to move. A mounting frame 209 is fixed to the front of the second threaded block 208, and the second threaded block 208 drives the mounting frame 209 to move so as to drive the grinding piece to move up and down. A laser sensor 210 is fixed to the lower surface of the mounting frame 209 to locate the position of the workpiece so that the grinder can quickly find the grinding position of the workpiece. A grinding assembly is provided on the mounting frame 209.

[0026] In this example, the mounting frame 209 is C-shaped with an opening facing downward. There are two laser sensors 210 symmetrically distributed front to back about the central axis of the mounting frame 209 , so as to calibrate the front and rear positions of the workpiece during grinding.

[0027] It should be noted that the grinding assembly includes a third motor 211 fixed to the front side of the mounting frame 209. The output shaft of the third motor 211 passes through and extends to the interior of the mounting frame 209 and is fixed with a rotating shaft 212. The output shaft of the third motor 211 drives the rotating shaft 212 to rotate. The other end of the rotating shaft 212 is rotatably connected to the rear inner wall of the mounting frame 209 through a bearing. A grinding block 213 is fixed to the outer side of the rotating shaft 212. The rotating shaft 212 drives the grinding block 213 to rotate to grind the workpiece. The thickness of the grinding block 213 is adapted to the distance between the front and rear inner walls of the mounting frame 209.

[0028] See also Figure 4-5 In order to improve the stability of the workpiece so as to perform multi-angle grinding on the workpiece, the fixing mechanism 3 in this embodiment includes a single-axis linear module 301, which is fixed to the inner bottom wall of the grinding table 1, and a support plate 302 is fixed to the upper surface of the single-axis linear module 301. The single-axis linear module 301 can drive the support plate 302 to move back and forth, thereby driving the workpiece to move back and forth so that the workpiece reaches the grinding position. A fourth motor 303 is fixed to the front of the support plate 302, and the output shaft of the fourth motor 303 passes through and extends to the rear side of the support plate 302, and is fixed to a fixed table 304. A fifth motor 305 is fixed to the right side of the fixed table 304, and the output shaft of the fifth motor 305 passes through and extends to the rear side of the support plate 302. The third threaded rod 306 is fixed to the interior of the fixed platform 304, and the output shaft of the fifth motor 305 drives the third threaded rod 306 to rotate. The other end of the third threaded rod 306 is fixed to the left inner wall of the fixed platform 304. The outer side of the third threaded rod 306 is threadedly connected to a third threaded block 307. The third threaded rod 306 drives the third threaded block 307 to move. There are two third threaded blocks 307, which are symmetrically distributed about the central axis of the third threaded rod 306. The upper surface of the third threaded block 307 passes through and extends to the upper side of the fixed platform 304, and is fixed with a clamping block 308. The third threaded block 307 drives the clamping block 308 to move, and the clamping block 308 clamps and fixes the workpiece.

[0029] In this example, two threads in opposite directions are distributed on the outer side of the third threaded rod 306, and are symmetrically distributed left and right about the central axis of the third threaded rod 306. Since a bidirectional thread is provided on the outer side of the third threaded rod 306, the two third threaded blocks 307 move relative to each other, so that the workpiece is clamped to avoid displacement during the grinding process.

[0030] The working principle of the above embodiment is:

[0031] (1) First, place the workpiece on the fixed table 304, and then turn on the fifth motor 305. The output shaft of the fifth motor 305 drives the third threaded rod 306 to rotate, and the third threaded rod 306 drives the third threaded block 307 to move. Since the outer side of the third threaded rod 306 is provided with a bidirectional thread, the two third threaded blocks 307 move relative to each other, and the third threaded block 307 drives the clamping block 308 to move. The clamping block 308 clamps and fixes the workpiece. Then, the laser sensor 210 is turned on to locate the position of the workpiece, so that the grinder can quickly find the grinding position of the workpiece.

[0032] (2) During the calibration process, the output shaft of the first motor 201 drives the first threaded rod 202 to rotate, and the first threaded rod 202 drives the first threaded block 203 to move, so as to drive the grinding block 213 to move left and right. The output shaft of the second motor 206 drives the second threaded rod 207 to rotate, and the second threaded rod 207 drives the second threaded block 208 to move, and the second threaded block 208 drives the mounting frame 209 to move, so as to drive the grinding block 213 to move up and down. At the same time, the single-axis linear module 301 can drive the support plate 302 to move forward and backward, thereby driving the workpiece to move forward and backward, so that the workpiece reaches the grinding position, and the third motor 211 is turned on. The output shaft of the third motor 211 drives the rotating shaft 212 to rotate, and the rotating shaft 212 drives the grinding block 213 to rotate to grind the workpiece. The fourth motor 303 can drive the fixed table 304 to flip, so as to adjust the grinding angle of the workpiece.
