[0036] At present, most of the chamfering operation of workpieces is processed by manual work, and is limited by the immaturity of the free edge polishing device, so that the overall processing efficiency of the workpieces is low.

[0037] The utility model provides a kind of free edge polishing device.

[0038] Please refer to Figure 1 And Figure 4In the embodiment of the utility model, the free edge polishing device 100 includes: the cutter assembly 2 is installed on the clamp 1, the cutter assembly 2 includes the movable shaft 21 extending along the first direction, and two cutter discs 22 fixedly installed on the movable shaft 21, two cutter discs 22 are arranged at intervals in the first direction, and a supporting wheel 23 is arranged between two cutter discs 22, wherein the cutter disc 22 is provided with a cutting edge 2211 on the side close to the supporting wheel 23; the driving motor 3 is installed on the clamp 1 and is drivingly connected with the cutter assembly 2 to drive the cutter disc 22 to rotate around the first direction axis, and the cutting edge 2211 on the side close to the supporting wheel 23 of two cutter discs 22 is used for polishing two edges of the workpiece to be processed in the first direction.

[0039] In the technical scheme of the utility model, the cutter assembly 2 has the movable shaft 21, the cutter disc 22 is sleeved on the movable shaft 21, and the cutting edge 2211 is arranged on the side close to the supporting wheel 23 of the cutter disc 22. During the machining operation, the driving motor 3 drives the movable shaft 21 to rotate along the first direction axis, the cutter disc 22 rotates around the first direction axis, and the cutting edge 2211 is used for contacting the edge of the workpiece to be processed and polishing. In order to polish two edges (such as two edges on one side of the plate body in the first direction) of the workpiece to be processed at the same time, the movable shaft 21 is sleeved with two cutter discs 22 and the supporting wheel 23, the supporting wheel 23 is arranged between two cutter discs 22, so that two cutter discs 22 are arranged at intervals in the first direction, the workpiece to be processed is placed on the side radially away from the cutter disc 22 and located between two cutter discs 22, the cutting edges 2211 of two cutter discs 22 correspond to two edges of the workpiece to be processed in the first direction, at this time, the driving motor 3 drives the movable shaft 21 to rotate along the first direction axis, and two cutter discs 22 polish two edges of the workpiece to be processed in the first direction at the same time. The driving motor 3 drives the cutter disc 22 to rotate for polishing, instead of manual operation to improve the machining efficiency, two cutter discs 22 are used to rotate for polishing two edges of the workpiece to be processed at the same time, and the efficiency of polishing the workpiece to be processed is further improved.

[0040] In order to ensure the polishing position and polishing amount of the blade 221 to the workpiece, and to ensure the machining precision, the cutter assembly 2 comprises a stop wheel 23 and a pressure plate 24. After the polishing machining of the workpiece by the cutter disc 22 is completed, the outer side of the stop wheel 23 in the radial direction abuts against the workpiece, and the workpiece and the movable shaft 21 cannot further approach in this direction, so that the cutter disc 22 cannot further polish the workpiece, thereby ensuring the machining amount and machining precision. In order to make the blade 2211 of one cutter disc 22 correspond to one side edge of the workpiece, and make the blade 2211 of the other cutter disc 22 correspond to the other side edge of the workpiece, so as to ensure the accuracy of the polishing position. The pressure plate 24 is sleeved on the movable shaft 21 and located on the side of the blade 221 close to the driving motor 3. The pressure plate 24 is used for abutting against the workpiece in the first direction. When abutting, the two blades 2211 correspond to the two side edges of the workpiece in the first direction, thereby ensuring the reliability of the polishing position.

[0041] Since the driving motor 3 drives the movable shaft 21 to rotate, and the stop wheel 23 and the pressure plate 24 are arranged on the movable shaft 21, the stop wheel 23 and the pressure plate 24 will rotate relative to the workpiece and also generate friction with the workpiece. In order to reduce the wear between the stop wheel 23, the pressure plate 24 and the workpiece, in an embodiment, the cutter assembly 2 further comprises a bearing 25, which is arranged between the stop wheel 23 and the movable shaft 21, and between the pressure plate 24 and the movable shaft 21. When the movable shaft 21 rotates N times, due to the existence of the bearing 25 and the friction between the stop wheel 23, the pressure plate 24 and the workpiece, the number of rotations of the stop wheel 23 and the pressure plate 24 relative to the workpiece is much smaller than N, thereby reducing the wear of the stop wheel 23, the pressure plate 24 and the workpiece.

[0042] Since the thickness of the workpiece in the first direction is different, it is necessary to adjust the distance between the two blades 221 in the first direction (i.e. it is necessary to correspondingly adjust the distance between the two cutter discs 22 in the first direction). In order to adjust the distance, the stop wheel 23 is detachably mounted on the movable shaft 21. The stop wheel 23 is provided in plurality, and the thickness of the plurality of stop wheels 23 in the first direction gradually increases. One of the stop wheels 23 is used for mounting on the movable shaft 21. Different thicknesses of stop wheels 23 are replaced to correspond to the different distances between the two blades 221 in the first direction. Alternatively, the distance between the two cutter discs 22 in the first direction is adjusted by adding a gasket between the two cutter discs 22.

[0043] In order to improve the processing efficiency, and slow down the wear speed of the single blade 221, so that the blade 221 has a longer service life, the cutter head 22 is provided with a plurality of blades 221 in the circumferential direction, and the plurality of blades 221 can be polished at the same time when the cutter head 22 rotates, thereby improving the processing efficiency of the cutter head 22. At the same time, the plurality of blades 221 can also reduce the wear of the single blade 221 when processing the same edge. Generally, the cutter head 22 is provided with 3-4 blades 221. When the blade 221 is worn, the installation angle of the blade 221 needs to be changed to polish other cutting edges 2211 on the blade 221, or the blade 221 needs to be replaced, so the installation mode of the blade 221 is detachable installation, and the plurality of cutting edges 2211 are arranged in the circumferential direction. Generally, one blade 221 is provided with four cutting edges 2211.

[0044] In order to process different sizes of chamfers, and process different thicknesses of workpieces, the cutter assembly 2 is provided with a plurality of cutter assemblies 2, the cutter assembly 2 further comprises a connecting shaft 26, the connecting shaft 26 extends in the first direction, and one end of the connecting shaft 26 in the first direction is detachably connected with the clamp 1; the other end is connected with the movable shaft 21. By replacing different cutter assemblies 2, different workpieces can be processed to obtain the desired chamfer.

[0045] In order to ensure that the workpiece can be stably pressed against the wheel 23 and the pressure plate 24, especially when the system precision cannot be high enough, it is difficult to make the pressure between the workpiece and the wheel 23 or the pressure plate 24 exactly 0 when the workpiece is pressed against the wheel 23 or the pressure plate 24. If the movable shaft 21 is rigidly connected with other parts, the part structure of the workpiece, the wheel 23 and the pressure plate 24 may be deformed when subjected to pressure. Therefore, it is required that the movable shaft 21 and the cutter head 22 can float in the axial direction and the radial direction, which mainly ensures that the top of the workpiece (the first direction) and the side surface guide (the second direction) can be stably pressed against the wheel 23 and the pressure plate 24.

[0046] Specifically, in order to realize the floating of the movable shaft 21 and the cutter head 22 in the axial direction of the movable shaft 21 and the cutter head 22, in an embodiment, the cutter assembly 2 comprises a first elastic member, the two ends of the first elastic member have a floating stroke of approaching or moving away from each other, and the two ends of the first elastic member are connected with the connecting shaft 26 and the movable shaft 22 respectively, so that the movable shaft 22 has a floating stroke in the axial direction thereof. In order to ensure that the workpiece can be stably pressed against the pressure plate 24, the pressure plate 24 needs to be subjected to a certain pressure, and the movable shaft 21 and the cutter head 22 float in the axial direction thereof under the action of the first elastic member. The first elastic member can be a buffer, a spring, a telescopic rod or the like.

[0047] Specifically, in order to realize the radial floating of the movable shaft 21, the radial direction of the movable shaft 21 is multidirectional, so as to achieve the effect, in an embodiment, the free edge polishing device 100 further comprises a mounting frame 4 and an adjusting assembly 5, the adjusting assembly 5 comprises a first connecting piece 51 and a second connecting piece 52, the first connecting piece 51 is rotatably installed on the mounting frame 4 along a second direction axis, and the clamp 1 is rotatably installed on the second connecting piece 52 along a third direction axis. When the movable shaft 21 floats in the radial direction, the adjusting assembly 5 rotates correspondingly to prevent the tool assembly 2 from deforming.

[0048] When the workpiece to be processed abuts against the wheel 23, the adjusting assembly 5 rotates correspondingly, and the workpiece to be processed and the wheel 23 just fit and the pressure is 0. In order to ensure stable fitting, there needs to be a certain pressure between the two, and in order to make the tool assembly 2 position recover after the workpiece to be processed moves away. Therefore, in an embodiment, the mounting frame 4 has a mounting hole 41 penetrating along a first direction, the clamp 1 penetrates the mounting hole 41, and the free edge polishing device 100 further comprises a resilient assembly 6, the resilient assembly 6 comprises a plurality of second elastic members 61, the second elastic members 61 extend radially along the mounting hole 41 and are arranged circumferentially along the mounting hole 41. One end of the second elastic member 61 is fixedly connected with the mounting hole 41, the other end has a radial activity stroke along the mounting hole 41, and is used for abutting against the clamp. In this way, the movable shaft 21 drives the cutter head 22 to float in the radial direction, and the second elastic member 61 can be specifically provided as a bumper or a spring.
