[0044] Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily intended to include all aspects of the present invention. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed by the present invention are not limited to any implementation. In addition, some aspects disclosed by the present invention can be used alone or in any appropriate combination with other aspects disclosed by the present invention.

[0045] Combination Figures 1 to 10 The example shown is a desktop multi-directional adjustable grinder according to an embodiment of the present invention, which is intended to replace the traditional grinder and polisher. It can pre-grind the wire rod end through a miniaturized, multi-angle adjustable desktop grinder. It is easy to operate and adjust, saves energy and reduces noise pollution.

[0046] The desktop multi-directional adjustable grinder according to the illustrated embodiment includes a base 100 , an adjustment movable rod 200 , an angle adjustment mechanism 300 , a deviation correction mechanism 400 and an operating platform 1000 .

[0047] The base 100 is used to support the structure of the entire grinder and is placed horizontally and firmly on an operating surface such as a desktop. The base 100 includes a bottom plate 101, a stand 102, and a mounting frame 103, all of which are made of high-strength steel. The bottom of the bottom plate 101 is horizontal to facilitate placement on a desktop for processing operations. It should be understood that the bottom plate 101 can also be fixed to a processing bracket, a processing platform, etc. by bolts at a suitable height to facilitate processing operations.

[0048] The stand 102 is fixedly connected to the base plate 101 or formed integrally therewith.

[0049] The mounting frame 103 is configured as a bearing body for mounting a driving mechanism, an adjusting moving rod 200 and a correcting mechanism 400. The angle adjusting mechanism 300 is mounted in the first end direction (ie, the head direction) of the adjusting moving rod 200.

[0050] Combination Figure 1 , Figure 2 , Figure 3As shown, the adjustment moving rod 200 adopts a square long rod structure, passes through the square through hole provided on the mounting frame 103, and is limited and fixed in position by the fixing knob 220. It should be understood that the adjustment moving rod 200 can move in the square through hole of the mounting frame 103, for example, by rotating the fixing knob 220 to release it, so that the adjustment moving rod 200 can move freely in the square through hole of the mounting frame 103, and when it moves to the required position, it can be tightened by operating the fixing knob 220 to achieve the limit and locking of the adjustment moving rod 200.

[0051] A connecting support plate 210 is fixed to the front end of the first end of the adjusting moving rod 200 , and an operating platform 1000 is fixed on the upper surface of the connecting support plate 210 , so that the operating platform 1000 is located in front of the first end of the adjusting moving rod 200 .

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the angle adjustment mechanism 300 is installed at a side position of the front end of the first end direction of the adjustment moving rod 200.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the deviation correction mechanism 400 is installed on the upper part of the mounting frame 103 and is rotatably connected to the mounting frame 103 through the ear portion 104 on the upper part of the mounting frame 300 .

[0054] Driving mechanism

[0055] Combination Figure 1 , Figure 2 , Figure 3 As shown, the driving mechanism includes a motor 10 as a main driver, a driving wheel 10A, and driven wheels (10B, 10C, 10D).

[0056] Combination Figure 1 As shown, the motor 10 is mounted on the mounting frame 103 and is close to the second end direction (i.e., the tail direction) of the adjusting moving rod 200. The output shaft of the motor 10 passes through the bearing installed on the mounting frame 103 and is connected to the driving wheel 10A on the mounting frame 103. The rotation output of the motor 10 synchronously drives the driving wheel 10A to rotate.

[0057] The first driven wheel 10B is installed at the bottom position of the angle adjustment mechanism 300, the second driven wheel 10C is installed at the top position of the angle adjustment mechanism 300, and the third driven wheel 10C is installed on the correction mechanism 400 and is located above the driving wheel 10A, so that the driving wheel 10A and the three driven wheels (10B, 10C, 10D) form a quadrilateral distribution.

[0058] In an optional embodiment, the driving wheel 10A is provided with a rib to prevent the sanding belt from falling.

[0059] Combination Figure 1 , Figure 2 , Figure 3 As shown, the abrasive belt 1 is mounted on the driving wheel 10A and three driven wheels (10B, 10C, 10D), and the driving wheel 10A is driven by the motor 10 to rotate synchronously. The wire rod to be processed is placed on the operating platform 1000, and the rotating abrasive belt 1 is used to grind the wire rod fracture.

[0060] Angle adjustment mechanism

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

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

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

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

[0065] Combination Figure 3 , Figure 6 As shown, the second fixing member 305 (such as a bolt) cooperates with the arc groove 303, and the second fixing member 305 is inserted into and passes through the 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 to limit and guide the angle and direction of rotation.

[0066] In this way, 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 operation can be performed on the angle adjustment plate 301. After adjustment, the first fixing member 304 and the second fixing member 305 are tightened to achieve limiting and fixing.

[0067] Combination Fig.11 The angle adjustment process shown is an optional embodiment, in which the angle adjustment is determined by the limit baffle 302, for example, the angle adjustment plate 301 is adjusted to a position where the limit baffle 302 is perpendicular to the operating platform 1000, so that the working area of ​​the abrasive belt 1 is perpendicular to the operating platform 2000, and an ideal grinding effect is obtained. There is a certain gap between the limit baffle 302 and the abrasive belt 1, and the limit baffle limits a certain distance to prevent the wire rod from over-pressing the abrasive belt 1 and damaging the abrasive belt.

[0068] Correction mechanism

[0069] Combination Figure 1 , Figure 2 As shown, the deviation correction mechanism 400 is provided with an L-shaped tensioning and pressing frame 401, and the rotational position of the tensioning and pressing frame 401 is connected to the ear 104 on the upper part of the mounting frame 300 through a pivot to achieve a rotational connection.

[0070] A fixing column 402 is provided on the upper surface of the mounting frame 300 at a position away from the ear 104, and a tensioning spring 403 is connected between the fixing column 402 and the tensioning frame 401. The tensioning spring 403 has a tendency to make the tensioning frame 401 move in a clockwise direction (maintain a compressed state) to maintain the tension of the sanding belt 1 on the driving wheel and the three driven wheels.

[0071] Combination Figure 1 , Figure 2 As shown, a pressure rod 404 is installed on the L-shaped tensioning frame 401, and the tensioning frame 401 can be pressed down by operating the pressure rod 401 to overcome the preload force of the tensioning spring 403, so that the driven wheel 10D installed on the tensioning frame 401 is pressed down.

[0072] Therefore, when installing the sanding belt, the tensioning frame 401 is pressed down by operating the pressure rod 401 so that the driven wheel 10D installed on the tensioning frame 401 is pressed down. Combined with the push-adjustment of the length of the movable rod 200, the tensioning spring 403 is subjected to a certain force, and the tensioning spring 403 is tightened to tighten the sanding belt 1. The fixing knob 220 is tightened to fix the position of the movable rod 200.

[0073] Furthermore, the operating rod 401 can be further pressed down to determine whether the force is appropriate, and the length of the adjustment moving rod 200 can be fine-tuned by twisting the fixing knob 220 .

[0074] Combination Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 As shown, the L-shaped tensioning and pressing frame 401 includes a first section 401A and a second section 401B connected to each other in an L-shape, and a tensioning spring 403 is connected between the first section 401A and the fixing column 401. The pressure rod 404 is arranged at the end of the second section 401B. It is pivotally connected to the ear 104 on the upper part of the mounting frame 300 at the L-shaped corner position and is rotatably connected to the mounting frame 103.

[0075] Combination Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 As shown, the deviation correction mechanism 400 further includes a tensioning adjustment hinge 405 , a deviation correction tensioning wheel 406 , a rotating shaft 407 and a deviation correction adjustment knob 410 .

[0076] The deviation-correcting tensioning wheel 406 is designed with a certain curvature, and the abrasive belt is deformed when tightened to better fit the abrasive belt.

[0077] In this embodiment, combined with Figure 8 , Fig. 9 , Fig.10As shown, the deflection-correcting tensioning wheel 406 is constructed as the aforementioned driven wheel 10D.

[0078] like Figures 7-10 As shown, the deviation correction tensioning wheel 406 is rotatably supported and mounted on the rotating shaft 407, and the rotating shaft 407 is screwed to the tensioning adjustment hinge 405 through threads. The tensioning adjustment hinge 405 has a rotating part 405A and a fixed part 404B. The rotating part 405A is combined with the fixed part 405B through a pivot structure to form an integral hinge structure, and the rotating part 405A can send rotation relative to the fixed part 405B. The fixed part 405B is fixed to the second section 401B of the tensioning press frame 401 by bolts.

[0079] Combination Fig. 9 and Fig.10 As shown, the deviation correction adjustment knob 410 includes an operating portion 410A and a threaded rod portion 410B integrally formed with the operating portion, the outer surface of the threaded rod portion 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 portion 405A of the tensioning adjustment hinge 405, thereby, by operating the deviation correction adjustment knob 410 to push the rotating portion 405A to send rotation, the deviation correction tensioning wheel 406 is adjusted to a certain angle, that is, a certain angle is formed between the deviation correction tensioning wheel 406 and the tensioning frame 401, so as to adjust the position of the sanding belt 1 on the deviation correction tensioning wheel 406, so as to center the sanding belt on the deviation correction tensioning wheel 406 and realize the sanding belt correction fine-tuning.

[0080] Combination Fig.10 As shown, a bearing is arranged inside the deflection correction tension wheel 406 along the direction of the rotation axis, and the rotating shaft 407 passes through the bearing of the deflection correction tension wheel 406 so that the deflection correction tension wheel 406 is supported on the rotating shaft 407 and can rotate freely relative to the rotating shaft 407. An external thread is arranged at one end of the rotating shaft 407 close to the tension adjustment hinge 405, so as to be tightened to the outer surface of the rotating part 405A of the tension adjustment hinge 405, so as to adjust the angle of the deflection correction tension wheel 406 by pushing the angle of the tension adjustment hinge 405.

[0081] Correction adjustment

[0082] Combination Figure 1 , Figure 2 , Figure 3 , Fig. 9 , Fig.10 as well as Fig.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 operated at a slow speed for debugging, the running state of the abrasive belt 1 is observed, and the deviation correction mechanism 400 is used for fine adjustment. By rotating the deviation correction adjustment knob 410, the deviation correction tensioning wheel 406 is adjusted to a certain angle, that is, a certain angle is formed between the deviation correction tensioning wheel and the tensioning press frame, and the position of the abrasive belt on the pulley is adjusted to adjust the abrasive belt 1 as much as possible to the center of the four pulleys (i.e., the driving wheel and the three driven wheels).

[0083] After adjustment, speed up the motor, press and place the wire rod on the operating platform 100, push one end of the wire rod slightly into the position of contacting the abrasive belt 1 for grinding, and pre-grind the fracture of the wire rod.

[0084] In an embodiment of the present invention, Fig.12 As shown, when the pressure rod 401 is pressed downward, the greater the deformation of the tensioning spring 403 is, the greater the pulling force on the tensioning frame 401 is, the greater the upward force of the deviation correction tensioning wheel 406 is, and the flexible tensioning belt eliminates the length error of the belt, improves the running stability, and increases the life of the belt.

[0085] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention.
