Description

Technical Field

[0001] This utility model belongs to the technical field of cutting tool surface treatment devices, and particularly relates to a device for polishing cutting tools. Background Technology

[0002] In the field of powder metallurgy, blade polishing is a crucial surface treatment process. Existing blade polishing equipment typically requires manual operation. Workers place the strung blades one by one onto each station of a turntable, which rotates the blades and polishes each station's blade. After the turntable completes one rotation and polishing is finished, the worker removes the blades one by one. This method is not only labor-intensive but also has a low degree of automation, with time intervals between each work cycle, resulting in low overall efficiency. Utility Model Content

[0035] The working process of this device is as follows: The operator places a feeding tray 501 (i.e., a tray with the connecting rod 001, on which blades are threaded) onto the feeding mechanism 500, and an empty tray onto the unloading mechanism 600; the feeding mechanism 500 moves the feeding tray 501 to the tray feeding station, and at the same time, the positioning seat 405 of the turntable mechanism 400 also moves to the turntable feeding station; the gripper 701 grabs the connecting rod on the feeding tray 501 and releases the connecting rod 001 to the positioning seat 405, and the positioning seat 405 moves the connecting rod 001 to the polishing station for polishing; after polishing, the positioning seat 405 moves to the turntable unloading station, the gripper 701 grabs the connecting rod 001 from the positioning seat 405 and releases the connecting rod 001 to the empty tray 601 of the unloading mechanism 600. The above process is repeated until all connecting rods 001 have been polished and transferred, completing one work cycle.

[0036] This device employs automation technology to automatically load, unload, grasp, release, and polish the feeder rod and blades, completely replacing the traditional manual method of placing each blade individually onto the turntable.

[0048] At least two material trays with positioning posts are installed on the loading positioning plate 502 and the unloading positioning plate 602, respectively.

[0049] The specific working process of this device is as follows: The operator places the loading tray 501 with the rod 001 installed on it onto the loading positioning plate 502, and then places the empty tray 601 onto the unloading positioning plate 602. The equipment is started, and the positioning plate moves the loading tray 501 to the loading station. Simultaneously, the positioning seat 405 of the turntable mechanism 400 also moves to the turntable loading station. If both are in position, no further movement is needed. The rod gripping mechanism 700 grips the rod at the loading station onto the positioning seat 405. After completion, the turntable mechanism 400 rotates and moves the rod to the polishing station, where the spray gun mechanism 300 polishes the blades on the rod.
