[0056] As shown in Figure 1As shown, the motor 10 is mounted on the mounting bracket 103 and is located near the second end (i.e., the tail end) of the adjusting rod 200. The output shaft of the motor 10 passes through the bearing mounted on the mounting bracket 103 and is connected to the drive wheel 10A on the mounting bracket 103. The rotation output of the motor 10 synchronously drives the drive wheel 10A to rotate.

The wire rod to be processed is placed on the operating platform 1000, and the broken edges of the wire rod are ground using the rotating abrasive belt 1.

[0060] Angular adjustment mechanism

[0061] Combination Figures 1 to 6 As shown, the angle adjustment mechanism 300 is configured to be mounted on the side of the adjustment moving rod 200 in the first end direction (i.e., the head direction) along the vertical direction.

[0062] The angle adjustment mechanism 300 includes an angle adjustment plate 301, a limiting baffle 302, a first fixing member 304 and a second fixing member 305. The limiting baffle 302 is installed at the front end of the angle adjustment plate 301 along the vertical direction, and the longitudinal direction of the limiting baffle 302 is horizontal with the vertical surface of the front end of the angle adjustment plate 301.

[0063] In an optional embodiment, the upper and lower ends of the limiting baffle 302 are respectively provided with waist-shaped holes, which are fastened to the front end of the angle adjusting plate 301 by bolts or other fasteners, and can adjust the distance between the limiting baffle 302 and the vertical surface of the front end of the angle adjusting plate 301.

[0064] Combination Figure 3 , Figure 6As shown, the rear end of the angle adjustment plate 301 is provided with a circular arc groove 303, and a first fixing member 304 (such as a bolt) is located in front of the circular arc groove 303, which is combined with the adjustment moving rod 200, for example, an installation shaft is provided at the position corresponding to the first fixing member of the adjustment moving rod 200, the angle adjustment plate 301 is sleeved on the installation shaft, and the angle adjustment plate 301 can rotate around the installation shaft, the first fixing member 304 can release the angle adjustment plate 301 (to allow it to rotate relative to the adjustment moving rod 200) by loosening operation, or limit the rotation of the angle adjustment plate 301 relative to the adjustment moving rod 200 by tightening operation.

[0065] In combination Figure 3 , Figure 6 As shown, the second fixing member 305 (such as a bolt) cooperates with the circular arc groove 303, the second fixing member 305 is inserted and passes through the circular arc groove 303, and is tightened or loosened to limit or allow the angle adjustment plate 301 to rotate relative to the adjustment moving rod 200, and limit and guide the angle and direction of rotation.

[0066] Therefore, when the angle of the angle adjustment plate 301 needs to be adjusted, the first fixing member 304 and the second fixing member 305 are loosened, and then the angle adjustment plate 301 can be adjusted to the desired position, and then the first fixing member 304 and the second fixing member 305 are tightened to limit and fix.

[0067] In combination Figure 11 As shown in the angle adjustment process, as an optional embodiment, the limiting baffle 302 is used to judge the angle adjustment, for example, the angle adjustment plate 301 is adjusted to a position state in which the limiting baffle 302 is perpendicular to the operation platform 1000, so that the working area of the abrasive belt 1 is perpendicular to the operation platform 2000, and the ideal polishing effect is obtained. Wherein, the limiting baffle 302 leaves a certain gap with the abrasive belt 1, and limits the distance through the limiting baffle to prevent the coil from being pressed too tightly to damage the abrasive belt.

[0068] Correction mechanism

[0069] In combination Figure 1 , Figure 2 As shown, the deviation rectifying mechanism 400 is provided with an L-shaped tensioning pressing frame 401, and the corner position of the tensioning pressing frame 401 is connected to the ear 104 on the upper part of the mounting frame 103 through a pivot, realizing rotary connection.

[0070] The upper surface of the mounting frame 103 is provided with a fixed column 402 at a position away from the ear portion 104. A tension spring 403 is connected between the fixed column 402 and the tension pressing frame 401. The tension spring 403 has a tendency to move the tension pressing frame 401 in a clockwise direction (maintains a compressed state) to maintain the tension state of the sand belt 1 wrapped around the driving wheel and the three driven wheels.

[0071] As shown in Figure 1 , Figure 2 , the L-shaped tension pressing frame 401 is provided with a pressing rod 404. The tension pressing frame 401 can be pressed down by operating the pressing rod 401 to overcome the pre-tightening force of the tension spring 403, so that the driven wheel 10D mounted on the tension pressing frame 401 is pressed down.

[0072] Therefore, when installing the sand belt, the tension pressing frame 401 is pressed down by operating the pressing rod 401 to press down the driven wheel 10D mounted on the tension pressing frame 401, combined with adjusting the length of the adjusting moving rod 200, so that the tension spring 403 is subjected to a certain force, the tension spring 403 is tensioned under the force, the sand belt 1 is tightly stretched, the fixed knob 220 is tightened, and the position of the adjusting moving rod 200 is fixed.

[0073] Further, the pressing rod 401 can be further pressed down to determine whether the force is appropriate, and the length of the adjusting moving rod 200 can be finely adjusted by twisting the fixed knob 220.

[0074] As shown in Figure 7 , Figure 8 , Figure 9 and Figure 10 , the L-shaped tension pressing frame 401 includes a first segment 401A and a second segment 401B connected in an L shape with each other. The tension spring 403 is connected between the first segment 401A and the fixed column 401. The pressing rod 404 is arranged at the end of the second segment 401B. The L-shaped corner is pivotally connected to the ear portion 104 on the upper portion of the mounting frame 103 and is pivotally connected to the mounting frame 103.

[0075] As shown in Figure 7 , Figure 8 , Figure 9 and Figure 10 , the deviation rectifying mechanism 400 further includes a tension adjusting hinge 405, a deviation rectifying tension wheel 406, a rotating shaft 407, and a deviation rectifying adjusting knob 410.

[0076] The deviation rectifying tension wheel 406 is designed with a certain curvature, and the sand belt deforms when tensioned to better fit the sand belt.

[0077] In this embodiment, as shown in Figure 8 , Figure 9 , Figure 10As shown, the corrective tensioning wheel 406 is configured as the aforementioned driven wheel 10D.

[0078] like Figures 7 to 10 As shown, the tensioning wheel 406 is rotatably supported and mounted on the rotating shaft 407, which is threaded onto the tension adjusting hinge 405. The tension adjusting hinge 405 has a rotating part 405A and a fixed part 405B. The rotating part 405A and the fixed part 405B are integrated into a hinge structure via a pivoting mechanism, allowing the rotating part 405A to rotate relative to the fixed part 405B. The fixed part 405B is bolted to the second section 401B of the tensioning frame 401.

[0079] Combination Figure 9 and Figure 10 As shown, the correction adjustment knob 410 includes an operating part 410A and a threaded rod part 410B integrally formed with the operating part. The outer surface of the threaded rod part 410B is provided with threads, which can be screwed into the threaded hole on the second section 401B of the tensioning frame 401 and pass through the threaded hole to abut against the rotating part 405A of the tension adjustment hinge 405. Thus, by operating the correction adjustment knob 410, the rotating part 405A is pushed to rotate, so that the correction tensioning wheel 406 is adjusted to a certain angle, that is, a certain angle is formed between the correction tensioning wheel 406 and the tensioning frame 401, so as to adjust the position of the sanding belt 1 on the correction tensioning wheel 406. The purpose is to center the sanding belt on the correction tensioning wheel 406 and realize the fine adjustment of the sanding belt correction.

[0080] Combination Figure 10 As shown, a bearing is provided inside the tensioning wheel 406 along the axis of rotation. The rotating shaft 407 passes through the bearing of the tensioning wheel 406, allowing the tensioning wheel 406 to be supported on the rotating shaft 407 and to rotate freely relative to the rotating shaft 407. The end of the rotating shaft 407 near the tensioning adjustment hinge 405 is provided with an external thread to be tightened onto the outer surface of the rotating part 405A of the tensioning adjustment hinge 405, thereby adjusting the angle of the tensioning wheel 406 by pushing the angle of the tensioning adjustment hinge 405.

[0081] Correction adjustment

[0082] Combination Figure 1 , Figure 2 , Figure 3 , Figure 9 , Figure 10 as well as Figure 12As shown, after the abrasive belt 1 is installed on the driving wheel and the three driven wheels and kept in a tensioned state, the motor is first run at a low speed for debugging, and the running state of the abrasive belt 1 is observed, and the correction mechanism 400 is used for fine adjustment. By rotating the correction adjusting knob 410, the correction tensioning wheel 406 is adjusted by a certain angle, that is, the correction tensioning wheel and the tensioning pressing frame form a certain angle, the position of the abrasive belt on the pulley is adjusted, and the abrasive belt 1 is adjusted to be as centered as possible on the four pulleys (that is, the driving wheel and the three driven wheels).

[0083] After adjustment, the motor is speeded up, the coil is placed on the operation platform 100, one end of the coil is pushed into the position of the abrasive belt 1 for grinding operation, and the fracture of the coil is pre-ground flat.

[0084] In the embodiment of the present application, the abrasive belt tensioning device is combined with the abrasive belt grinding device. Figure 12 As shown, when the pressing rod 401 is pressed downward, the greater the deformation of the tensioning spring 403, the greater the tension on the tensioning pressing frame 401, and the greater the upward force of the correction tensioning wheel 406. The flexible tensioning abrasive belt eliminates the length error of the abrasive belt, improves the running stability, and prolongs the service life of the abrasive belt.

[0085] Although the present application has been disclosed with reference to the preferred embodiments, it is not intended to limit the present application. Those skilled in the art can make various modifications and improvements without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application shall be subject to the definition of the claims.
