[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1 to Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of the cutting assembly of the present application. Figure 2 yes Figure 1 Schematic diagram of a cutting assembly in cooperation with a cutting wheel. The cutting assembly in the present application is applied to a cutting device, and is used to clamp a workpiece to be cut so that the cutting wheel can cut it. The cutting assembly 1000 includes a cutting body 1100 and a stopper 1200.

[0019] The cutting body 1100 is provided with a cutting groove 1110, and the groove walls 1111 of the cutting groove 1110 are respectively provided with stoppers 1200 for limiting the swing of the cutting grinding wheel 1300, that is, the number of the stoppers 1200 is two, and at least part of the stoppers 1200 protrudes from the groove wall 1111 of the cutting groove 1110 toward the wheel surface of the cutting grinding wheel 1300. When cutting a workpiece to be cut, at least part of the workpiece to be cut is fed into the cutting groove 1110, and then the cutting grinding wheel 1300 penetrates into the cutting groove 1110 from the notch of the cutting groove 1110 to cut the workpiece to be cut.

[0020] In the prior art, when the cutting wheel penetrates into the cutting groove to cut the workpiece to be cut, the cutting wheel has a large movable range in the cutting groove and is easy to swing when rotating at high speed, resulting in low cutting accuracy and deviation in the size of the product after cutting. However, the present application sets a raised limiter in the cutting groove to reduce the movable range of the cutting wheel in the cutting groove, reduce the swing of the cutting wheel, and improve the cutting accuracy.

[0021] In this embodiment, in order to facilitate the maintenance of the cutting assembly 1000, the stopper 1200 and the cutting body 1100 are independent of each other and can be detachably assembled together. Specifically, when the stopper 1200 is worn due to the swing of the cutting wheel 1300, the stopper 1200 can be directly removed and replaced, thereby reducing the difficulty of maintenance and the maintenance cost. Figure 1 and Figure 2 As shown, a groove is formed on the groove wall 1111 of the cutting groove 1110, and the stopper 1200 is embedded in the groove and at least partially protrudes from the groove toward the cutting wheel 1300, or in other application scenarios, the stopper 1200 is fixed to the groove wall 1111 of the cutting groove 1110 by an adhesive (such as glue). Of course, in other embodiments, the stopper 1200 can also be integrally formed with the cutting body 1100, which is not limited here.

[0022] At the same time, in an application scenario, the limit member 1200 is a limit rod. In order to extend the service life of the limit member 1200 and reduce the wear of the limit member 1200 within the same use time, the limit member 1200 is made of a highly wear-resistant material, such as tungsten steel or ceramics.

[0023] Continue reading Figure 1 The cutting body 1100 is provided with a receiving groove 1120 whose continuity is interrupted by the cutting groove 1110, for receiving the workpiece to be cut. When the workpiece to be cut needs to be cut, the workpiece to be cut is fed into the receiving groove 1120 and at least partially fed into the cutting groove 1110, wherein the size of the receiving groove 1120 matches the size of the workpiece to be cut.

[0024] See also Figure 3 , Figure 3 yes Figure 1 The cutting body 1100 includes a cutting fixing seat 1130 , a cutting base 1140 and a cutting pressing block 1150 .

[0025] The cutting fixed seat 1130, the cutting base 1140, and the cutting pressing block 1150 are stacked in sequence, that is, the cutting base 1140 is arranged between the cutting fixed seat 1130 and the cutting pressing block 1150, wherein the cutting fixed seat 1130 and the cutting base 1140 remain relatively still, and the cutting pressing block 1150 can move relative to the cutting base 1140 and the cutting fixed seat 1130, and is used to clamp the workpiece to be cut received by the receiving trough 1120, and at the same time, the cutting groove 1110 sequentially penetrates the cutting pressing block 1150 and the cutting base 1140 and extends to the cutting fixed seat 1130. Specifically, the cutting groove 1110 does not penetrate the cutting fixed seat 1130.

[0026] The material receiving groove 1120 is disposed on a side of the cutting base 1140 away from the cutting fixing base 1130. Optionally, at least one end of the material receiving groove 1120 extends to one end of the cutting base 1140. Figure 3 In the embodiment, the material receiving trough 1120 extends from one end of the cutting base 1140 to the other end. At the same time, the cutting base 1140 and the cutting fixing base 1130 can be formed in one piece, or can be independently and detachably connected to each other, for example, connected by bolts, buckles, etc. It is worth noting that by setting the cutting base 1140 and the cutting fixing base 1130 to be detachably connected, different cutting bases 1140 can be replaced for different types of workpieces to be cut for the same cutting fixing base 1130, thereby reducing the cost of the equipment, and when one of the cutting base 1140 and the cutting fixing base 1130 is damaged, it can be easily replaced.

[0027] In addition, when the cutting fixing seat 1130 is detachably connected to the cutting base 1140, in order to ensure that the cutting base 1140 can be accurately positioned on the cutting fixing seat 1130 during the assembly process, continue to refer to Figure 3 A first positioning rail 1131 is protruded from the cutting fixing seat 1130 toward the side of the cutting base 1140, and a first positioning groove 1141 for accommodating the first positioning rail 1131 is provided on the side of the cutting fixing seat 1130 toward the cutting base 1140. At the same time, the extension direction of the first positioning rail 1131 and the first positioning groove 1141 is the same as the extension direction of the material receiving groove 1120, thereby preventing the cutting base 1140 from deviating from the cutting fixing seat 1130 in the direction perpendicular to the extension of the material receiving groove 1120 during the assembly process, thereby preventing the subsequent material receiving groove 1120 from being unable to accurately receive the workpiece to be cut.

[0028] Specifically, after the receiving trough 1120 receives the workpiece to be cut, the cutting pressing block 1150 is driven by a cylinder or other element to move toward the cutting base 1140 to press the workpiece to be cut received by the receiving trough 1120, and when the cutting is completed, the cutting pressing block 1150 is driven by a cylinder or other element to move away from the cutting base 1140 to release the workpiece. It should be noted that in other embodiments, the cutting pressing block 1150 may not be provided, and other methods such as vacuum adsorption may be used to press and release the workpiece, which is not limited here.

[0029] See also Figure 1 and Figure 4 , Figure 4 yes Figure 1 In this embodiment, the limiting member 1200 includes a first limiting rod 1210 , a second limiting rod 1220 , a third limiting rod 1230 and a fourth limiting rod 1240 .

[0030] The extension direction of the first limiting rod 1210 and the second limiting rod 1220 is perpendicular to the extension direction of the cutting groove 1110, and the two ends of the third limiting rod 1230 are respectively abutted against the first limiting rod 1210 and the second limiting rod 1220 to form an "I" shape, and the fourth limiting rod 1240 is arranged parallel to the third limiting rod 1230. At the same time, the first limiting rod 1210, the second limiting rod 1220 and the third limiting rod 1230 are all embedded in the groove on the side wall of the cutting base 1140, and the fourth limiting rod 1240 is embedded in the groove on the side wall of the cutting block 1150.

[0031] Of course, in other embodiments, the limiter 1200 may also be in other forms such as a limiter block to limit the swing of the cutting wheel 1300, and the limiter 1200 may also be only disposed on the cutting block 1150 or the cutting base 1140, which is not limited here. In summary, the present application does not limit the structure and specific position of the limiter 1200, as long as it at least partially protrudes from the groove wall 1111 of the cutting groove 1110 and can reduce the swing of the cutting wheel 1300.

[0032] See also Figure 5 to Figure 6 , Figure 5 is a schematic structural diagram of an embodiment of the cutting device of the present application, Figure 6 yes Figure 5 Schematic diagram of the exploded structure of the cutting device. The cutting device 2000 includes a feeding assembly 2100 and a cutting assembly 2200.

[0033] The feeding assembly 2100 and the cutting assembly 2200 can move relative to each other. The feeding assembly 2100 is used to feed at least part of the workpiece to be cut into the cutting groove 2210 of the cutting assembly 2200. The cutting assembly 2200 has the same structure as the cutting assembly 1000 in the above embodiment. For details, please refer to the above embodiment, which will not be repeated here.

[0034] The feeding assembly 2100 is provided with a feeding trough 2110, and the feeding trough 2110 is connected with the receiving trough 2220 of the cutting assembly 2200. When cutting the workpiece to be cut, the workpiece to be cut is set on the feeding trough 2110 in advance and one end of the workpiece to be cut protrudes from the feeding trough 2110 to the feeding assembly 2100. After receiving the numerical control instruction, the feeding assembly 2100 drives the workpiece to be cut to move relative to the cutting assembly 2200. After the feeding assembly 2100 moves a specified distance, one end of the workpiece to be cut protruding from the feeding assembly 2100 enters the receiving trough 2220 and further enters the cutting groove 2210, and then the cutting grinding wheel (not shown) penetrates into the cutting groove 2210 to cut the workpiece to be cut.

[0035] See also Figure 7 , Figure 7 yes Figure 5 The exploded structural diagram of the feeding assembly 2100 includes a feeding fixing seat 2220 , a feeding base 2230 and a feeding pressing block 2240 .

[0036] The feeding fixed seat 2220, the feeding base 2230 and the feeding pressure block 2240 are stacked in sequence, that is, the feeding base 2230 is arranged between the feeding pressure block 2240 and the feeding fixed seat 2220, and at the same time, the feeding fixed seat 2220 and the feeding base 2230 remain relatively still, and the feeding pressure block 2240 can move relative to the feeding base 2230 to compact or loosen the workpiece to be cut set on the feeding trough 2110. Specifically, after the workpiece to be cut is set on the feeding trough 2110 in advance, the feeding pressure block 2240 moves toward the feeding base 2230 under the drive of components such as cylinders to compact the workpiece to be cut, and then after cutting is completed, the feeding pressure block 2240 moves away from the feeding base 2230 under the drive of components such as cylinders to loosen the workpiece. It should be noted that in other embodiments, the feeding pressing block 2240 may not be provided, and other methods such as vacuum adsorption may be used to press and release the workpiece, which is not limited here.

[0037] The feeding trough 2110 is arranged on the side of the feeding base 2230 away from the feeding fixed seat 2220. Optionally, at least one end of the feeding trough 2110 extends to one end of the feeding base 2230. Figure 7 In the embodiment, the feeding trough 2110 extends from one end of the feeding base 2230 to the other end.

[0038] Among them, the feeding fixed seat 2220 is the core positioning element of the feeding component 2100. During the cutting process, the feeding fixed seat 2220 receives CNC instructions, and then drives the feeding base 2230 to move a specified distance synchronously relative to the cutting component 2200.

[0039] Meanwhile, the feeding base 2230 and the feeding fixed seat 2220 can be integrally formed or independently and detachably connected to each other, for example, connected by bolts, buckles, etc. It is worth noting that by arranging the feeding base 2230 and the feeding fixed seat 2220 to be detachably connected, different feeding bases 2230 can be replaced for different types of workpieces to be cut for the same feeding fixed seat 2220, thereby reducing the cost of the equipment, and when one of the feeding base 2230 and the feeding fixed seat 2220 is damaged, it can be easily replaced.

[0040] In addition, when the feeding base 2230 is detachably connected to the feeding fixed seat 2220, in order to ensure that the feeding base 2230 can be accurately positioned on the feeding fixed seat 2220 during the assembly process, the feeding fixed seat 2220 is provided with a second positioning slide rail 2221 protruding from the side of the feeding base 2230, and the feeding base 2230 is provided with a second positioning groove 2231 for accommodating the second positioning slide rail 2221 on the side of the feeding fixed seat 2220. At the same time, the extension direction of the second positioning slide rail 2221 and the second positioning groove 2231 is the same as the extension direction of the feeding trough 2110, thereby preventing the feeding base 2230 from offsetting the feeding fixed seat 2220 in the direction perpendicular to the extension of the feeding trough 2110 during the assembly process, thereby preventing the subsequent feeding trough 2110 and the receiving trough 2220 from being unable to dock.

[0041] In order to better understand the cutting device 2000 in the present application, Figures 5 to 7 The working process of the cutting device 2000 is introduced in detail.

[0042] Before the workpiece to be cut is placed in the feed slot 2110 , the feed pressing block 2240 is away from the feed base 2230 .

[0043] After the workpiece to be cut is placed in the feed slot 2110 and one end of the workpiece to be cut protrudes from the feed slot 2110 out of the feed assembly 2100, the feed pressing block 2240 is moved to the feed base 2230 to press the workpiece to be cut in the feed slot 2110, and then the feed assembly 2100 moves a specified distance according to the instruction to dock the feed slot 2110 with the cutting slot 2210, so that the end of the workpiece to be cut protruding from the feed assembly 2100 enters the receiving slot 2220 and further enters the cutting slot 2210, and then the cutting wheel penetrates into the cutting slot 2210 to complete the cutting of the workpiece to be cut.

[0044] In other embodiments, when the feeding assembly 2100 moves a specified distance and the feeding trough 2110 is docked with the receiving trough 2220, the workpiece to be cut can be moved from the feeding trough 2110 to the receiving trough 2220 by a robotic arm or other mechanism. Specifically, the present application does not impose any restrictions on how the workpiece to be cut is moved from the feeding trough 2110 to the receiving trough 2220.

[0045] In addition, the present application also discloses a cutting device, which includes a base, a feeding assembly, a cutting assembly, a cutting grinding wheel and a driving assembly.

[0046] The feeding assembly has the same structure as the feeding assembly in the aforementioned embodiment, and the cutting assembly has the same structure as the cutting assembly in the aforementioned embodiment. For details, please refer to the above embodiment, which will not be repeated here.

[0047] The feeding assembly and the cutting assembly are both arranged on the base and can move relatively on the base. The feeding assembly is used to feed at least part of the workpiece to be cut into the cutting groove of the cutting assembly.

[0048] The driving component can be a driving element such as a robotic arm. After the feeding component feeds the workpiece to be cut into the cutting groove of the cutting component, the driving component drives the cutting grinding wheel from the notch of the cutting groove into the cutting groove to cut the workpiece to be cut.

[0049] In order to reduce the burrs on the ports of the workpiece to be cut after cutting, facilitate the operation of the subsequent process, and reduce production costs, the cutting grinding wheel is a resin grinding wheel. In one application scenario, the cutting grinding wheel is a thin-sheet resin grinding wheel. Of course, in other embodiments, the cutting grinding wheel can also be a tungsten steel grinding wheel or other hard grinding wheel, which is not limited here.

[0050] In summary, different from the prior art, the cutting assembly of the present application sets a limit member on the relative groove walls in the cutting groove to limit the swing of the cutting wheel. At least part of the limit member protrudes from the groove wall of the cutting groove toward the wheel surface of the cutting wheel, thereby narrowing the range of movement of the cutting wheel in the cutting groove, ultimately reducing the swing of the cutting wheel and ensuring cutting accuracy.

[0051] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
