In addition, a plurality of cutters are clamped through the corresponding cutter fixing devices 2 at the same time and synchronously move along with the conveying device 1, so that automatic machining is realized, and the machining efficiency is further improved.
As shown in fig. 1, since the space of the tool processing site is limited, and the conveyor 1, if it is one-way conveying, needs to be continuously provided with the tool fixing device 2 thereon, it is impossible to satisfy the real automation requirement; the conveying device 1 in this embodiment is a closed loop conveying line, which includes a supporting platform 11 and an endless conveying belt 12; the annular conveying belt 12 is arranged on the supporting platform 11 and driven by a motor to realize circulating operation; the plurality of cutter holders 2 are circumferentially and uniformly fixed to the endless conveyor belt 12, and realize a conveying form of a closed loop chain with the circulating operation of the endless conveyor belt 12. It should be noted that, in this embodiment, the motor for driving the annular conveyer belt 12 to operate is a servo motor, and drives the annular conveyer belt 12 to reciprocate through forward and reverse rotation of the servo motor, so that the cutters on the cutter fixing device 2 reciprocate along with the annular conveyer belt 12, and repeated polishing of the cutter edge is realized, so that sharpening can be completed when two cutter polishing devices 3 are in the previous and subsequent paths, and multiple polishing is not required to follow the annular conveyer belt 12 to circularly move.
As shown in fig. 2 and 3, when the cutter blade portion is polished, the clamping block cannot cover the cutter blade portion of the cutter to expose the cutter blade portion for polishing, at this time, the cutter polishing device 3 presses the cutter blade portion with a force, the grinding wheel of the cutter polishing device 3 rotates at a high speed to rub the cutter blade portion, the cutter blade portion (the portion not clamped by the clamping block) thereby generates high-frequency vibration, the thickness of the cutter blade portion becomes thinner as the polishing depth becomes deeper, and small gaps (particularly in the process of polishing the second surface) are easily generated in the polishing process of the blade portion without support, thereby affecting the quality and quality of the cutter. In this embodiment, the tool fixing device 2 is provided with two clamping blocks 21 and two blade supporting plates 22, the two clamping blocks 21 clamp and fix the tool from two sides of the tool, the two blade supporting plates 22 are arranged in one-to-one correspondence with the two clamping blocks 21, each blade supporting plate 22 is movably connected with the corresponding clamping block 21 and can stand up or retract, when one surface of the tool blade is polished, the blade supporting plate 22 corresponding to the surface of the tool blade is retracted so as to expose the surface of the tool blade for polishing, the blade supporting plate 22 corresponding to the other surface of the tool blade stands up so as to be attached to support the tool blade, thereby sharing the pressure applied to the tool blade by the tool polishing device 3, reducing the vibration of the tool blade, dispersing the stress of the tool blade, reducing the compression deformation condition of the tool blade in the polishing process, so that the tool blade is not easy to generate gaps in the polishing process, and improving the quality and quality of the tool.
As shown in fig. 2 and fig. 4, because the cutters have sequential polishing sequences, and the cutter blade parts on two sides of the cutter before polishing are in a right-angle structure, when one side of the cutter blade part is polished, the cutter blade part of the polished surface is changed from a right angle to an obtuse angle, the surface which is not polished is still right-angle and polished at the next cutter polishing device 3, if the same blade part supporting openings are adopted for the blade part supporting plates 22 on two sides, the polished first side blade part and the blade part supporting plates 22 cannot be completely attached, and the cutter blade part is easy to generate a notch; in this embodiment, the top end of the blade support plate 22 corresponding to the first grinding surface of the cutter is provided with an obtuse angle support opening 222, and the obtuse angle support opening 222 is tightly attached to the blade of the cutter of the first grinding surface to provide support; a right-angle supporting opening 221 is formed at the top end of the blade supporting plate 22 corresponding to the second grinding surface of the cutter, and the right-angle supporting opening 221 is attached to the right-angle blade of the second grinding surface of the cutter to provide support; in addition, the tops of the two blade support plates 22 and the side facing the cutter are both provided with slopes matched with the cutting edges of the cutter, so that the tops of the blade support plates 22 are not easy to interfere with the polishing head of the cutter polishing device 3 during polishing.
As shown in fig. 1 and 4, the tool fixing device 2 is further provided with a fixing bottom plate 24, and the tool fixing device 2 is fixedly installed on the annular conveying belt 12 through the fixing bottom plate 24 and circularly moves along with the annular conveying belt 12; the two clamping blocks 21 are longitudinally arranged on the fixed bottom plate 24 side by side, each clamping block 21 is in sliding connection with the fixed bottom plate 24 through a screw nut pair 25, and the two clamping blocks 21 clamp and fix the cutter from two sides of the cutter through manual or electric adjustment of the screw nut pair 25. When the screw nut pair 25 adopts an electric adjustment mode, a power device other than one device may be respectively disposed at the starting position of the conveying device 1 and at two sides of the conveying device 1, and the screw nut pair 25 is driven to operate by the power device so as to realize synchronous movement of the two clamping blocks 21; the power device arranged after the clamping of the cutter is separated from the screw-nut pair 25, so that the circular movement of the cutter fixing device 2 is not affected, and the structure of the equipment is simplified. In addition, the tool fixing device 2 of the embodiment can be suitable for clamping tools with different thicknesses.
As shown in fig. 1 and 4, since the conveying device 1 of the present embodiment adopts an up-down circulating conveying line, the tool fixing device 2 is turned over from above the supporting platform 11 to the bottom of the supporting platform 11, and then turned over from the bottom of the supporting platform 11 to the top of the supporting platform 11, so as to realize circulating movement; in the whole process, the cutter fixing device 2 not only needs to bend at the initial position and the final position of the annular conveying belt 12, but also falls down under the action of gravity of the cutter fixing device 2 when the cutter fixing device is folded to the bottom of the supporting platform 11, so that the connection between the cutter fixing device 2 and the annular conveying belt 12 is possibly unstable; in this embodiment, the center of the fixing base plate 24 is fixedly connected with the endless conveyor belt 12, so as to reduce the hard connection area between the fixing base plate 24 and the endless conveyor belt 12, and facilitate the turning of the tool fixing device 2 at the bending position along with the endless conveyor belt 12 during the circulating motion. In addition, the front side and the rear side of the bottom of the fixed bottom plate 24 are respectively provided with a magnet 241 capable of magnetically attracting the annular conveyer belt 12, when the fixed bottom plate 24 is in a horizontal state along with the annular conveyer belt 12, the front end and the rear end of the fixed bottom plate 24 are attracted to the annular conveyer belt 12 through the magnets 241, especially when the cutter fixing device 2 is folded to the bottom of the supporting platform 11 in a circulating process, the cutter fixing device 2 falls down under the action of self gravity, the unstable connection between the cutter fixing device 2 and the annular conveyer belt 12 can be caused, the magnetic attraction between the magnets 241 and the annular conveyer belt 12 increases the connection area and the connection strength of the fixed bottom plate 24 and the annular conveyer belt 12 in the horizontal state, and the connection stability of the two is increased; when the fixed bottom plate 24 moves to the bending position along with the annular conveying belt 12, at this time, the connecting section of the annular conveying belt 12 and the fixed bottom plate 24 is in a bending state, the front end and the rear end of the fixed bottom plate 24 overcome the attraction force of the magnet 241 and the annular conveying belt 12 and are separated from the outer surface of the annular conveying belt 12, namely, the front end and the rear end of the fixed bottom plate 24 tilt relative to the annular conveying belt 12 so as to be convenient for turning, and when the fixed bottom plate 24 moves along with the annular conveying belt 12 and is in a horizontal state again, the front end and the rear end of the fixed bottom plate 24 are attracted on the annular conveying belt 12 again through the magnet 241 so as to realize stable connection.
As shown in fig. 1,4, 5 and 6, since the two sides of the tool are sequentially polished, the blade support plates 22 on both sides of the tool need to be alternately erected and retracted, and accordingly, a power mechanism needs to be provided for realizing the operation, but if the power mechanism is provided for driving the action of the blade support plates, whether electrically driven, pneumatically driven or hydraulically driven, a control line, an electric wire or a pipeline needs to be connected to the tool fixture 2, and the tool fixture 2 moves along with the conveying device 1, so that the connection of the tool fixture 2 and the power mechanisms on both sides is extremely complex and is prone to failure. In the embodiment, an up-down overturning structure is adopted between the blade supporting plate 22 and the corresponding clamping block 21 to realize standing or folding; the edge supporting plate 22 and the clamping block 21 are connected through a hinge 26 with a torsion spring, a locking assembly 23 is arranged between the edge supporting plate 22 and the clamping block 21, and the edge supporting plate 22 can automatically upwards turn over and be attached to the cutter edge under the unlocking of the locking assembly 23 and the action of the hinge 26 so as to realize the supporting of the edge supporting plate 22 on the cutter edge in the polishing process; the blade supporting plate 22 is folded downwards under the locking of the locking component 23, so that the blade of the cutter to be polished on the other side is exposed and polished at the next position; specifically, the locking assembly 23 includes a buckle 231 and a latch hook 232, the buckle 231 is mounted on the blade support plate 22, the latch hook 232 is movably mounted on the clamping block 21 through a torsion spring hinge, when the blade support plate 22 is turned down to a fixed position, the buckle 231 on the blade support plate 22 is just clamped in the latch hook 232 on the clamping block 21 to achieve locking, and at this time, the blade support plate 22 is in a state of turning down and retracting.
As shown in fig. 1, 5, 6 and 7, each tool polishing device 3 is provided with an unpowered driving device 4 correspondingly, and the unpowered driving devices 4 are mounted on the conveying device 1; in the process that the cutter fixing device 2 and the cutter move along with the conveying device 1, the unpowered driving device 4 unlock and lock the locking component 23 in sequence, and meanwhile, a downward turning driving force is generated on the blade supporting plate 22 so as to realize the downward turning of the blade supporting plate 22. Specifically, the unpowered driving device 4 comprises a deflector rod 41 and a guide frame 42, the deflector rod 41 and the guide frame 42 are positioned on one side of the conveying device 1, and the corresponding cutter polishing device 3 is positioned on the other side of the conveying device 1; In the process that the cutter fixing device 2 and the cutter move along with the conveying device 1, before polishing, the deflector rod 41 dials the lock hook 232 to turn over and release the buckle 231, the locking component 23 is unlocked, the edge supporting plate 22 is turned up, and the lock hook 232 is reset under the action of the torsion spring after being turned over so as to realize the next locking of the buckle 231. After finishing the polishing, the upturned blade support plate 22 needs to be retracted and is realized by the guide frame 42; The buckle 231 is provided with a guide wheel 233, the guide frame 42 comprises a guide rail 421, a high support cross rod 422 and a low support cross rod 423, the high support cross rod 422 and the low support cross rod 423 are arranged front and back to form a height difference, two ends of the guide rail 421 are respectively arranged on the high support cross rod 422 and the low support cross rod 423, the guide rail 421 is provided with a vertical surface which is gradually twisted to the end from an initial horizontal surface, when the grinding of a certain cutter blade is finished, the cutter fixing device 2 moves continuously along with the conveying device 1, the guide wheel 233 on the blade support plate 22 in an upright state is axially in a horizontal state at the moment, and contact with the horizontal plane of the head end of the guide rail 421, along with the continuous movement of the tool fixing device 2, the guide rail 421 of the guide frame 42 generates a downward turning driving force to the guide wheel 233 and the blade support plate 22 connected with the guide wheel 233 through the buckle 231, the blade support plate 22 gradually turns downward, when the guide wheel 233 slides to the tail end of the guide rail 421, the blade support plate 22 is completely in a downward turning state, and the buckle 231 overcomes the torsion of the torsion spring between the lock hook 232 and the clamp block 21 and locks the lock hook 232 again, so that the downward turning and folding of the blade support plate 22 are realized. It should be noted that, along with the downward turning of the guide wheel 233, the angle of the guide wheel 233 itself is also changed, that is, the guide wheel is gradually turned from the horizontal state to the vertical state in the axial direction, and finally slides out from the vertical surface at the tail end of the guide rail 421. In addition, it should be noted that, since the tool fixing device 2 moves along with the conveying device 1, the locking assembly 23 between the clamping block 21 and the blade supporting plate 22 moves relatively to the deflector rod 41 and the guide frame 42, and the unlocking of the locking assembly 23 by the deflector rod 41, the locking of the locking assembly 23 by the guide frame 42 and the downward turning driving force to the blade supporting plate 22 are generated, so that the retraction and the erection of the two blade supporting plates 22 are realized; Therefore, the embodiment can realize power-free driving, does not need to additionally provide a power mechanism to drive the unlocking and locking of the locking assembly 23, greatly simplifies the structure and improves the reliability of the equipment.
As shown in fig. 3, since the cutting tool generates a cutting object during cutting, the cutting object may remain on the contact surface of the clamping block 21 and the edge support plate 22, resulting in that the edge support plate 22 is not easily in an upright state after being turned up, and the edge support plate 22 and the supporting surface of the cutting tool cannot be tightly adhered to provide strong support, so that a notch may occur in the polishing process of the cutting tool; in this embodiment, when the blade support plate 22 is raised, a gap for accommodating the cutting material is left between the bottom end surface of the blade support plate 22 and the top end surface of the clamping block 21, and this gap can be realized by the design of the hinge 26, so that the blade support plate 22 is not easily affected by the cutting material during the upturning process and cannot be completely erected.
As shown in fig. 8 and 9, since the connection between the blade support plate 22 and the clamping block 21 is a spring hinge, when the blade support plate 22 is turned up under the action of the torsion spring, a certain impact force is generated on the tool face and the tool blade, and since the tool blade is thin, especially after one side of the tool blade is polished, the impact force may cause deformation of the tool face and the tool blade, and finally affect the quality and quality of the tool. In this embodiment, a pneumatic damping structure is provided on the top of the clamp block 21 to cushion the rising motion of the blade support plate 22; specifically, the top of the clamping block 21 is provided with a groove 211, a top pin 212 is connected in a sliding manner in the groove 211, and a piston 216 is arranged at the bottom of the top pin 212, so that a closed air cavity is formed between the top pin 212 and the groove 211, and a return spring 213 is arranged in the air cavity to realize the return of the top pin 212 after the downward movement; the clamping block 21 is also provided with an exhaust hole 214 communicated with the air cavity, in the process of rising the blade support plate 22, the bottom end of the blade support plate 22 presses the ejector pin 212, the ejector pin 212 moves downwards and presses the air in the air cavity, so that the air is gradually discharged from the exhaust hole 214, namely, the air pressure in the air cavity is reduced in a small hole exhaust mode, so that the buffering of the blade support plate 22 is realized, and the blade support plate 22 is prevented from being started up as an impact cutter blade. If the elastic member is used for buffering, there is a problem that the supporting force of the blade supporting plate 22 to the cutter blade is reduced by continuously elastically pressing the blade supporting plate 22 after buffering is completed. Compared with spring damping, the pneumatic damping structure of the embodiment does not generate rebound to press the blade supporting plate so that the supporting force of the blade supporting plate to the cutter blade is reduced. In addition, the return spring 213 returns the knock pin 212, and has a small elastic force, and a small degree of pressing force against the blade support plate 22 is negligible.
In addition, a step surface 215 for limiting is formed in the groove 211, when the top pin 212 is retracted into the groove 211 under the extrusion of the blade support plate 22, the bottom end of the top pin 212 abuts against the step surface 215, so that the top pin 212 is not moved down any more, and at this time, the length of the top pin 212 extending out of the clamping block 21 is the clearance value between the blade support plate 22 in the standing state and the clamping block 21, that is, the cooperation of the top pin 212 and the step surface 215 ensures the clearance value between the blade support plate 22 and the clamping block 21 for accommodating the cutting object, so that the blade support plate 22 cannot cross the support surface under the action of the hinge 26.
As shown in fig. 1 and 10, the tool polishing device 3 in this embodiment includes a bracket 32, a polishing head 33, a motor 34 and a regulating cylinder 35, the bracket 32 is mounted on the supporting platform 11, a cylinder body portion of the regulating cylinder 35 is fixed on the bracket 32, and a telescopic end of the regulating cylinder 35 is connected with the motor 34 to realize the propulsion of the polishing head 33; a motor shaft of the motor 34 is connected with the polishing head 33 to drive the polishing head 33 to rotate; when the cutter moves to the cutter polishing device 3 along with the annular conveying belt 12, the polishing head 33 is aligned with the cutter blade and advances towards the cutter side, the motor 34 is started, the motor 34 drives the polishing head 33 to rotate so as to polish the cutter blade, the annular conveying belt 12 drives the cutter to reciprocate, meanwhile, the push rod of the adjusting cylinder 35 also gradually stretches out, the polishing head 33 is ensured to be always contacted with the cutter blade, and the polishing effect of the cutter blade is ensured.
As shown in fig. 10, when the grinding head 33 grinds the cutter blade portion, problems such as vibration of the machine, deformation of the cutter, and the like are caused, and interference of these external factors causes non-uniformity in the grinding depth of the cutter blade portion. In this embodiment, the counter support wheel 31 for supporting the blade support plate 22 is mounted on the support 32 and located at the position of the counter polishing head 33, when the tool fixing device 2 and the tools move to the tool polishing device 3 along with the endless conveyor belt 12, the counter support wheel 31 abuts against the back surface of the blade support plate 22 and generates rolling motion with the blade support plate 22, and when the tool is polished, on one hand, the blade support plate 22 supports the tool blade more strongly under the support of the counter support wheel 31, and on the other hand, because the counter support wheel 31 is the opposite support structure of the tool polishing device 3, the positioning function can be achieved, the interference of external factors such as machine vibration and tool deformation is reduced, and the consistency of the polishing depth of each tool blade is ensured.
