Description

Technical Field

[0001] The utility model relates to the technical field of tool grinding, in particular to an artificial diamond tool grinding device. Background Art

[0002] The grinding of artificial diamond cutting tools uses grinding equipment and technology to ensure the sharpness and durability of the cutting tools. The finishing of the machined surface is carried out through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metal materials. The surface shapes processed include planes, internal and external cylindrical surfaces, conical surfaces, and other surfaces.

[0003] In the existing technology, such as the fully automatic CNC equipment for grinding natural diamond cutting tools proposed in patent application number "CN202022698814.0", the tool grinding position and angle are precisely adjusted by setting a precision rotating spindle, an XY-axis adjustment platform and a precision reciprocating grinding platform, and a high-precision precision air-suspended spindle is used to finely control the position of the grinding wheel. It can complete the sharpening of precision natural diamond internal arc tools, filling the gap of CNC precision grinding equipment for natural diamond internal and external arc tools at home and abroad.

[0004] However, in the above patent application, when processing the cutting tools, it is generally necessary to process multiple cutting tools, and the cutting tools need to be placed in the equipment one by one manually. It is impossible to automatically and quickly load multiple cutting tools, which affects the processing efficiency. It is also impossible to easily adjust the end direction of the movable arm used to fix the cutting tool to be processed. External tools are also needed. The height of the movable arm cannot be adjusted to accommodate cutting tools of different lengths, and the applicability is poor. Utility Model Content

[0029] A circular ring 9 is movably installed inside the circular shell 8, and a number of sockets are opened on the upper surface of the circular ring 9. Support columns 10 are inserted into the inside of the several sockets. A support spring is installed between the bottom end of the support column 10 and the bottom end of the socket. A sliding rod 11 is fixedly installed on the upper surface of the support column 10, and two splints 12 are slidably installed on the outside of the sliding rod 11. A tension spring is installed on the outside of the sliding rod 11 and between the two splints 12. The two ends of the tension spring are fixedly connected to the two splints 12 respectively.

[0030] The inside of the circular shell 8 is connected to a gear 17 through a shaft, and a number of tooth grooves are provided on the outer wall of the ring 9 near the bottom, and the several tooth grooves are engaged with the gear 17. A motor 1 is installed on the bottom surface of the circular shell 8, and the output end of the motor 1 is connected to the gear 17 through a shaft. The gear 17 is driven to rotate by the motor 1, and cooperates with each tooth groove to make the ring 9 rotate, which can drive the remaining knife bodies 13 to rotate.

[0031] The front end surface of the base shell 2 is connected to a movable door 6 through a hinge. The bottom surface of the grinding table 1 is installed with a second motor, and the output end of the second motor is connected to the grinding disc 3 through a shaft. The outer wall of the fixed head 14 is installed with a fixing bolt 23.

[0032] When in use, the movable door 6 is opened, and then the tool body 13 to be ground is placed in sequence on the upper end of the support column 10 and located between the two clamping plates 12. When placed, the two clamping plates 12 separate, the support spring is stretched, and under the action of the rebound force of the support spring, the two clamping plates 12 are brought close to each other, clamping and fixing the bottom of the tool body 13, so that the position of the tool body 13 can be well fixed on the upper end of the support column 10.
