Description

Technical Field

[0001] The utility model relates to the technical field of milling cutter processing, in particular to a milling cutter passivation device. Background Technique

[0002] By deburring, flattening and polishing the cutting tool, the quality of the cutting tool is improved and the service life is extended. This is a process after the cutting tool is precision ground and before coating. Its name is not yet unified at home and abroad. It is called "edge passivation", "edge strengthening", "edge honing", "edge preparation" or "ER (Edge Radiusing) treatment".

[0003] For the edge passivation technology, its purpose is to solve the defect of the microscopic notch of the edge of the cutting tool after grinding, reduce or eliminate its peak value, and achieve smoothness and flatness, making it both sharp and durable. After retrieval, a mobile and convenient milling cutter passivation device with the publication number of CN 205085747 U in the prior art makes the placement plate rotate more stably by setting rollers, and cooperates with the first motor and the second motor to make the passivation effect of the milling cutter on the placement plate better. By setting a pushing device, the second screw rod moves horizontally left and right on the first screw rod, and the clamping device moves horizontally forward and backward on the second screw rod, enabling the milling cutter to move horizontally forward, backward, left and right, making the movement of the milling cutter more convenient. Moreover, a clamping device is set, and the fifth motor drives the main gear and the driven gear to rotate, enabling the milling cutter to rotate and making the passivation effect better.

[0004] It is found through actual application that although the foregoing technical solution can passivate multiple milling cutters in multiple directions at one time, since the placement plate does not have an auxiliary installation structure and the milling cutters need to be manually taken and placed, the passivation speed is seriously affected. At the same time, the milling cutter is a cylindrical body, and this technical solution only passivates the cutting head part of the milling cutter, and the edge of the cutter body is not passivated, so the passivation effect is not comprehensive enough.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1-4 A milling cutter passivation device comprises a carrying platform, the top surface of the carrying platform is rotatably connected to a placement disk 1, a placement hole 101 for placing a tool rod at the bottom of the milling cutter is provided on the top surface of the placement disk 1, a positioning rod 2 is installed behind the top surface of the carrying platform, an extension plate 201 is installed on the top of the positioning rod 2, a passivation disk 3 is arranged below the front end of the extension plate 201, an electric telescopic rod 202 for controlling the height between the passivation disk 3 and the placement disk 1 is movably installed on the top surface of the passivation disk 3 and the bottom surface of the front end of the extension plate 201, a feeding structure for feeding the milling cutter into the placement hole 101 is also arranged at the side of the carrying platform relative to the positioning rod 2, the side of the placement disk 1 is also connected to a replacement structure for rotating the placement disk 1 to replace the placement hole position after the feeding structure is loaded, and a passivation structure for passivating the milling cutter is also arranged on the bottom surface of the passivation disk 3.

[0024] Furthermore, the extension plate 201 is connected through the positioning rod 2, and the extension plate 201 is further used to connect the passivation disk 3. The three form a stable vertical structure, and the electric telescopic rod 202 is used to control the up and down movement of the passivation disk 3, so as to achieve approaching or moving away from the placement disk 1. When the passivation disk 3 is close to the placement disk 1, the passivation milling cutter head and the exposed part of the tool rod are polished, and when it is away from the passivation disk, the polishing is completed.

[0025] Furthermore, the placement tray 1 is loaded with materials through the loading structure, and the electric push rod is started so that its output end pushes the milling cutter placed in the silo to fall from the through hole. The tray 4023 arranged under the through hole receives and supports the milling cutter. At this time, the two sides of the milling cutter are protected by two clamps 404. When the bottom of the milling cutter collides with the tray 4023, the vibration sensor is used to start the nut screw 4 to drive the feeding arm 402 to move toward the placement tray 1.

[0026] Furthermore, when the feeding arm 402 moves, the limit plate 403 set on its front wall starts to move synchronously. Once the limit plate 403 moves, it will drive the gear 406 to move together. At this time, the gear 406 will touch the No. 1 gear rod 407, and the two will form a meshing and make the gear 406 rotate while moving forward. When the gear 406 rotates, it drives the double-headed screw 405 connected to itself to start rotating. When the double-headed screw 405 rotates, it will move the two clamps 404 threadedly connected to itself relative to each other, so that the two clamps 404 are close to each other to clamp the milling cutter body, so that the milling cutter can be driven by the limit plate 403 to move toward the placement tray 1.

[0027] Further, after the milling cutter is driven to move towards the placing disk 1, when the gear 406 contacts the second tooth bar 408, since the second tooth bar 408 is located above the gear 406, at this time the rotation direction of the gear 406 relative to the first tooth bar 407 is opposite. Therefore, the gear 406 rotates in reverse, driving the connected double-headed screw rod 405 to rotate in reverse, driving the two clamping plates 404 to separate relatively, loosening the clamped body of the milling cutter. At this time, the milling cutter drops down into the placing hole 101. Further, the sponge pad 102 is used to wrap the milling cutter to prevent it from swinging during passivation. Furthermore, the diameter of the placing hole 101 is larger than the diameter of the milling cutter but does not exceed one-third. The placing hole 101 is designed with a surplus to prevent the milling cutter from not being in the hole after it drops.

[0028] Further, when the gear 406 is driven to reach the end of the second tooth bar 408, the output shaft connected to the feeding arm 402 will reach the end of the nut screw rod synchronously. At this time, the nut screw rod rotates in reverse, driving the feeding arm 402 to move backward and reset. Correspondingly, the limit plate 403 will be driven to reset together. Then, the electric push rod is started again to push the milling cutter to drop from the through hole to the tray 4023 for the next round of feeding.

[0029] Further, when the milling cutter drops into the placing hole 101, the servo motor is started to drive the linkage gear 6 to rotate. Since the rotation circumference of the linkage gear 6 is equal to the interval length of the placing hole 101, every time the linkage gear 6 rotates one circle, it will drive the gear ring 5 to rotate self to change the relative position of the placing hole 101, thus realizing transposition. At the same time, the servo motor is started at intervals, and each interval time is equal to the feeding time of the feeding structure once.

[0030] Further, the polishing structure uses the reduction motor to drive the driven gear 7 connected to the connecting rod to rotate self. Since multiple driven gears 7 are engaged with each other, the driven gear 7 is driven, thus driving the sleeve 8 connected to its bottom surface to polish and passivate the milling cutter.

[0031] During use, the placing disk 1 is fed through the feeding structure. When the milling cutter drops into the placing hole 101, the transposition structure is started simultaneously to transpose the placing hole 101. When multiple placing holes 101 are full, the electric telescopic rod 202 is used to control the up and down movement of the passivation disk 3, so as to realize approaching the placing disk 1. When the passivation disk 3 approaches the placing disk 1, the cutter head of the milling cutter and the exposed part of the cutter bar are polished and passivated. At this time, the reduction motor is started to drive the driven gear 7 connected to the connecting rod to rotate self. Since multiple driven gears 7 are engaged with each other, the driven gear 7 is driven, thus driving the sleeve 8 connected to its bottom surface to polish and passivate the milling cutter. After the milling cutter is passivated, the passivation disk 3 is reset, and the passivated milling cutters are taken out in turn.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
