[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figure 1 - Figure 10, this embodiment provides an annular belt type burr processor, including a mounting base 1, on which two groups of first guide rollers 2 are rotatably connected. A vertical first guide rail 3 and a horizontal second guide rail 4 are installed between the two groups of first guide rollers 2. Two vertical third guide rails 5 are slidably connected to the second guide rail 4. A width adjusting member 11 for driving the two third guide rails 5 to slide along the second guide rail 4 is installed on the mounting base 1. Specifically, the width adjusting member 11 includes a width adjusting motor 111 and a bidirectional lead screw 112 fixedly connected to the end of the width adjusting motor shaft. The two third guide rails 5 are respectively threadedly connected to the thread portions of different rotation directions of the bidirectional lead screw 112;

[0041] A first sliding seat 6 and a second sliding seat 7 are slidably connected to the first guide rail 3. An angle adjusting member 13 for driving the second sliding seat 7 to slide along the first guide rail 3 is installed on the mounting base 1; A third guide roller 51 is rotatably connected to one end of the third guide rail 5. A third sliding seat 8 is slidably connected to the third guide rail 5. A length adjusting member 12 for driving the third sliding seat 8 to slide is installed on the mounting base 1; A guiding member 9 is installed on the second sliding seat 7 and the third sliding seat 8. A second guide roller 10 is rotatably connected to the first sliding seat 6;

[0042] A follow-up adjusting member 14 is also installed on the mounting base 1. The follow-up adjusting member 14 is used to drive the first sliding seat 6 to move along with the movement of the second sliding seat 7 and can make the position of the first sliding seat 6 relatively fixed after the second sliding seat 7 stops;

[0043] In addition, the grinding machine of this application embodiment further includes a sand belt 15. The sand belt 15 is sequentially wound around the first guide roller 2, the second guide roller 10, the third guide roller 51 and the guiding member 9. A driving motor 17 for driving the first guide roller 2 to rotate is also installed on the mounting base 1; Among them, the two sections of the sand belt 15 located in the two third guide rail sections are parallel to each other;

[0044] A fixture 18 for clamping the workpiece 22 is also installed on the first guide rail 3;

[0045] In addition, the grinding machine should be equipped with a controller 23, and the controller 23 is electrically connected to the driving sources of the width adjusting member 11, the length adjusting member 12, and the angle adjusting member 13. Furthermore, the grinding area 151 of the sand belt 15 is adjusted through the controller 23, so that the sand belt 15 in the grinding area 151 adapts to the grinding work of two parallel surfaces of different widths and lengths of the workpiece 22, and when the two surfaces to be ground are not parallel, it adapts to the grinding work of two surfaces with different included angles through the angle adjusting member 13.

[0046] The following is a further introduction in combination with a specific usage scenario. First, the angle adjusting member 13, the length adjusting member 12, and the width adjusting member 11 are adjusted according to the grinding surface requirements of the workpiece 22 to be ground; Such as the following situations:

[0047] Case 1: When there are two parallel surfaces of the workpiece 22 to be polished (such as the parallel surfaces of the workpieces of types D, E, and F in Figure 10 ): At this time, adjust the length adjusting member 12 and the width adjusting member 11 so that the distance between the two third guide rails 5 can be adjusted, so that the distance between the two parallel abrasive belts 15 at the two third guide rails 5 is equal to the width of the workpiece 22, and the distance between the third guide roller 51 and the guide member 9 on the third sliding seat 8 is equal to the length of the workpiece 22. After clamping the workpiece 22 with the fixture 18 in this way, push the workpiece 22 between the two third guide rails 5. In this way, the two abrasive belts 15 on the two third guide rails 5 can polish the two parallel surfaces of the workpiece 22.

[0048] Case 2: When there are three surfaces of the workpiece 22 to be polished (such as the workpiece of type D in Figure 10 ), if the workpiece 22 is a cuboid, at this time, under the adjustment conditions of Case 1, further adjust the position of the second sliding seat 7 on the first guide rail 3 through the angle adjusting member 13 so that the three guide members 9 are on a straight line. In this way, the abrasive belt 15 at the three guide member 9 sections can polish the surface to be polished of the workpiece 22 that is perpendicular to the two parallel surfaces.

[0049] Case 3: When the two surfaces of the workpiece 22 to be polished are not parallel, such as the two surfaces to be polished are two convex surfaces (such as the workpiece of type E in Figure 10 ); or when the workpiece 22 has a tapered groove (such as the workpiece of type F in Figure 10 ), the two surfaces to be polished are two concave surfaces; at this time, the angle adjusting member 13 needs to be adjusted. Specifically, by adjusting the positions of the two third guide rails 5 and the position of the second sliding seat 7 on the first guide rail 3, the positions of the guide members 9 on the first guide rail 3 and the guide members 9 on the two third guide rails 5 are adjusted, so that the angle of the abrasive belt 15 at the guide member 9 on the first guide rail 3 is the same as the included angle of the two planes to be polished of the workpiece 22. In this way, when the driving motor 17 drives to drive the abrasive belt 15 to run, the two non-parallel surfaces of the workpiece 22 can be polished.

[0050] Further, during the adjustment process, the length of the abrasive belt 15 between the first guide roller 2 and the second guide roller 10, the length of the abrasive belt 15 between the first guide roller 2 and the third guide roller 51, the length of the abrasive belt 15 between the third guide roller 51 and the guide member 9 on the third guide rail 5, and the length of the abrasive belt 15 between the three guide members 9 will all change accordingly. To ensure the stability of the adjustment and grinding processes of the grinding machine, it is necessary to ensure that the abrasive belt 15 remains in a tensioned state during the adjustment and grinding processes, and to ensure that the abrasive belt 15 does not become disengaged from the first guide roller 2, the second guide roller 10, the third guide roller 51, and the guide member 9 during the adjustment and grinding processes. In the present invention, the position of the first slide block 6 on the first guide rail 3 is adjusted by installing a follow-up adjustment member 14, so that when the positions of the third guide rail 5, the second slide block 7, and the third slide block 8 change, the position of the first slide block 6 will adaptively change under the drive of the abrasive belt 15 to ensure that the abrasive belt 15 always remains in a tensioned state. After the adjustment, the position of the first slide block 6 is immediately locked by the follow-up adjustment member 14, so that the abrasive belt 15 runs relatively stably during the grinding process.

[0051] Overall, through the cooperation of the first guide rail 3, the second guide rail 4, the third guide rail 5, the guide member 9, the first guide roller 2, the second guide roller 10, the third guide roller 51, the length adjustment member 12, the width adjustment member 11, the angle adjustment member 13, and the follow-up adjustment member 14, the included angle of the grinding surface of the abrasive belt 15, the length and width of the grinding area 151 of the abrasive belt 15 are adjusted, and the two parallel surfaces, or three mutually perpendicular surfaces, or two non-parallel surfaces of the workpiece 22 can be ground simultaneously. At the same time, the tapered groove on the surface of the workpiece 22 can also be ground, improving the versatility and grinding efficiency of the grinding machine.

[0052] Referring to Figure 1 - Figure 3 、 Figure 6 、 Figure 8 , as a specific implementation manner of the embodiment of the present application, the guide member 9 includes a U-shaped mounting frame 91, on which a first adjustment roller 92 and two second adjustment rollers 93 are rotatably connected. The two second adjustment rollers 93 are respectively rotatably connected to the top and bottom of the mounting frame 91, and the installation positions of the two second adjustment rollers 93 are closer to the workpiece 22 than the first adjustment roller 92.

[0053] Further, referring to Figure 1 and Figure 2, the abrasive belt 15 includes a base fabric and abrasive grains 1511 fixed to one side of the base fabric by an adhesive. The abrasive belt 15 has a grinding area 151 and connection areas 152 located on both sides of the grinding area 151. The abrasive grains 1511 are located in the grinding area 151. The first adjusting roller 92 of the guide member 9 is located on the side of the base fabric where the abrasive grains 1511 are not adhered, and the two second adjusting rollers 93 are located on the side of the base fabric where the abrasive grains 1511 are adhered, and the two second adjusting rollers 93 are located in the connection areas 152.

[0054] Combined with a specific usage scenario, the side of the abrasive belt 15 with the abrasive grains 1511 is set as the grinding area 151 and the connection areas 152 located on both sides of the grinding area 151. The first adjusting roller 92 of the guide member 9 is located on the side of the base fabric where the abrasive grains 1511 are not adhered, and the two second adjusting rollers 93 are located on the side of the base fabric where the abrasive grains 1511 are adhered, and the two second adjusting rollers 93 are located in the connection areas 152. In this way, not only can the angle of the abrasive belt 15 be adjusted by the three guide members 9 and the operation of the abrasive belt 15 be assisted in guiding, but also the two second adjusting rollers 93 do not contact the abrasive grains 1511. Furthermore, when the abrasive belt 15 operates, the abrasive grains 1511 will not cause wear to the second adjusting rollers 93, and it can ensure that the grinding of the two angled surfaces of the workpiece 22 at the vertex position of the workpiece 22 is not affected. In this way, the stability and reliability of the grinding work and the rational use of the grinding machine can be ensured.

[0055] Refer to Figure 3 - Figure 6 , as a specific implementation manner of the embodiment of the present application, the follow-up adjusting member 14 includes a top plate 141 fixedly connected to the top end of the first guide rail 3 and a tension spring 140. One end of the compression spring 146 is fixedly connected to the top plate 141, and the other end is fixedly connected to the first sliding seat 6. The follow-up adjusting member 14 further includes a plurality of guide columns 142 fixedly connected to the side surface of the first sliding seat 6, an armature 143 slidably connected to the guide columns 142, a connecting plate 144 fixedly connected to the side of the guide columns 142 away from the first sliding seat 6, an electromagnet 145 installed on the connecting plate 144, a compression spring 146 installed between the armature 143 and the connecting plate 144, a clamping block 147 fixedly connected to the armature 143, and a clamping bar 148 fixedly connected to the side surface of the first guide rail 3. The clamping bar 148 and the clamping block 147 have mating teeth 149. It should be noted here that the electromagnet 145 needs to be electrically connected to the controller 23.

[0056] Combined with a specific usage scenario, when it is necessary to adjust the shape of the grinding area 151 of the abrasive belt 15, it is necessary to energize the electromagnet 145 through the controller 23 to adsorb the armature 143, so that the compression spring 146 is further compressed, and then the clamping block 147 is moved away from the first sliding seat 6. In this way, the locking between the first sliding seat 6 and the first guide rail 3 is released. Then, when adjusting the positions of the guide member 9 and the third guide rail 5 through the length adjusting member 12, the width adjusting member 11 and the angle adjusting member 13, the tension spring 140 can ensure that the abrasive belt 15 does not come off between the first guide roller 2, the second guide roller 10 and the guide member 9, thereby ensuring the stability of the adjustment work. After the adjustment is completed, the power supply of the electromagnet 145 is disconnected through the controller 23, and then under the action of the compression spring 146, the clamping block 147 abuts against the tooth 149 of the clamping strip 148, thereby ensuring that the position of the first sliding seat 6 will not move due to the operation of the abrasive belt 15 during grinding, ensuring the stability of the grinding work.

[0057] Referring to Figure Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , as a specific implementation manner of the embodiment of the present application, the length adjusting member 12 includes a second screw rod 121 rotatably connected to the second guide rail 4. The second screw rod 121 is threadedly connected to the third sliding seat 8. A worm 122 is rotatably connected to the third guide rail 5, and a worm gear 123 meshing with the worm 122 is rotatably connected to the screw rod. A sliding hole 1221 is formed in the middle of the worm 122, and a limiting pin 124 is fixedly connected in the sliding hole 1221. A driving rod 125 is rotatably connected to the mounting seat 1. A sliding groove 1251 is formed in the driving rod 125. The driving rod 125 is slidably connected to the sliding hole 1221, and the limiting pin 124 is located in the sliding groove 1251. A length adjusting motor 126 for driving the driving rod 125 to rotate is installed on the mounting seat 1.

[0058] Combined with a specific usage scenario, first, if you want to adjust the positions of the mounting seats 1 on the two third guide rails 5, two sets of drives can be designed to adjust the two mounting seats 1 respectively. However, this requires ensuring that the drives on the two mounting seats 1 are synchronized to ensure that the position adjustment of the mounting seats 1 on the second guide rail 4 can be synchronized. The accuracy of the synchronous adjustment of the mounting seats 1 on the two third guide rails 5 is relatively troublesome, and two driving motors 17 are required.

[0059] Furthermore, in the embodiment of the present application, the positions of the two mounting seats 1 can be adjusted synchronously with a driving motor 17 with higher precision. The specific adjustment process and adjustment principle are as follows: after the positions of the two third guide rails 5 on the second guide rail 4 are adjusted by the width adjustment member 11, the spacing between the mounting seats 1 on the two third guide rails 5 is adjusted to adapt to the grinding of two parallel sides of workpieces 22 of different widths. During adjustment, the worm 122 will slide along the driving rod 125. After adjustment, the driving rod 125 is driven to rotate by starting the length adjustment motor 126. The cooperation of the slide slot 1251 on the driving rod 125 and the stop pin 124 on the worm 122 will cause the two worms 122 to rotate synchronously, thereby driving the two worm wheels 123 to rotate. The rotation of the two worm wheels 123 can drive the two second screws 121 to rotate. Further, under the cooperation of the threads of the second worm 122 and the mounting seat 1, the two slides are controlled to slide synchronously, thereby realizing the distance between the slide on the third slide rail and the third guide roller 51, thereby realizing the length adjustment of the sanding belt 15 at the grinding position to adapt to the grinding of two parallel surfaces of workpieces 22 of different lengths. The embodiment of the present application can control the position adjustment of the two slides by a length adjustment motor 126, and will not affect the width adjustment between the third slide rails, thereby reducing the cost investment of the driving source and ensuring the synchronization of the position adjustment of the two slides.

[0060] Reference Figure 6 As a specific implementation of the embodiment of the present application, the angle adjustment member 13 includes a first screw 131, the first screw 131 is threadedly connected to the second slide seat 7, an angle adjustment motor 132 is installed on the mounting seat 1, and the angle adjustment motor 132 is connected to the first screw 131 through a bevel gear set 133.

[0061] In combination with specific usage scenarios, when adjusting the position of the mounting seat 1 on the first guide rail 3, the driving motor 17 is started, and then the first screw 131 is driven to rotate under the transmission of the bevel gear set 133, and the mounting seat 1 on the first guide rail 3 is driven to slide along the first guide rail 3 through the spiral cooperation between the first screw 131 and the mounting seat 1, so as to achieve the purpose of adjusting the position of the mounting seat 1 on the first guide rail 3, and then adjust the grinding surface angle of the abrasive belt 15 to adapt to the grinding work of the surface of the workpiece 22 with different angles. The mutual cooperation between the first screw 131 and the thread surface of the mounting seat 1 can also ensure that the position of the mounting seat 1 will be relatively stable after adjustment, and the problem of position change is not easy to occur, thereby ensuring the stability of the grinding work.

[0062] Reference Figure 1 and Figure 6, as a specific implementation manner of the embodiment of the present application, the fixture 18 includes a support base 181 slidably connected to the first guide rail 3. An installation plate 182 is fixedly connected to the support base 181 by bolts. Two locking screw rods 183 are threadedly connected to the installation plate 182. A clamping plate 184 is fixedly connected to the bottom of the locking screw rod 183, and a handle 185 is fixedly connected to the top of the locking screw rod 183.

[0063] Combined with the specific usage scenario, when performing the grinding work on the workpiece 22, first place the workpiece 22 on the support base 181, make the surface of the workpiece 22 to be ground face the abrasive belt 15, then rotate the two handles 185 respectively, and then adjust the two locking screw rods 183 to make the two locking screw rods 183 spiral downwards, and then use the two clamping plates 184 and the support base 181 to clamp the workpiece 22 to provide stable clamping for the grinding of the workpiece 22. Finally, the position of the support base 181 on the first guide rail 3 can be adjusted so that the surface of the workpiece 22 to be ground gradually approaches the abrasive belt 15, and then the surface of the workpiece 22 can be ground by the abrasive belt 15.

[0064] Refer to Figure 1 and Figure 2 , as a specific implementation manner of the embodiment of the present application, an angle plate 191 is installed on the second sliding seat 7, and an elastic cord 192 is installed between the guide members 9 on the second sliding seat 7 and the guide members 9 on the first sliding seat 6.

[0065] Combined with the specific usage scenario, the settings of the angle plate 191 and the elastic cord 192 can facilitate timely understanding of the actual included angle of the three guide members 9 when adjusting the included angle of the three guide members 9. Then, the staff can understand the included angle of the abrasive belt 15 through the angle plate 191 and the elastic cord 192 to adapt to the angle of the workpiece 22, which improves the convenience and accuracy of the adjustment of the grinding machine and also improves the adjustment efficiency of the grinding machine.

[0066] Refer to Figure 1 and Figure 3 , as a specific implementation manner of the embodiment of the present application, a protective plate 20 is installed between the first guide roller 2 and the second guide roller 10 on the mounting seat 1, and the protective plate 20 is a folding plate.

[0067] Combined with the specific usage scenario, by installing the protective plate 20 between the first guide roller 2 and the second guide roller 10, and the protective plate 20 is in a foldable style, the abrasive belt 15 between the second guide roller 10 and the first guide roller 2 can be isolated. And when the position of the second guide roller 10 is adjusted, the protective plate 20 can also be folded and extended accordingly, which can improve the safety of the grinding environment when grinding the surface of the workpiece 22.

[0068] Refer to Figure 1 and Figure 3, as a specific implementation manner of the embodiment of the present application, two grinding platforms 21 are further installed on the mounting base 1, and the two grinding platforms 21 are respectively installed at two groups of first guide rollers 2.
