Description

Technical Field

[0001] This utility model relates to the field of diamond tool processing technology, and in particular to a grinding device for PCD diamond tool processing. Background Technology

[0002] Diamond, commonly known as "diamond," is a mineral composed of carbon, an allotrope of graphite, with the chemical formula C, and is the precursor to diamonds. Diamond is the hardest naturally occurring substance in nature. Graphite can be used to form synthetic diamonds under high temperature and pressure. Diamond has a wide range of uses, including in handicrafts, industrial cutting tools, and is also a precious gemstone. Diamond has been used as a superhard cutting tool material for centuries. In the history of cutting tool development, from the late 19th to the mid-20th century, high-speed steel was the primary material. In 1927, Germany first developed cemented carbide cutting tools, which were then widely used. In the 1950s, Sweden and the United States synthesized synthetic diamonds, ushering in an era dominated by superhard materials for cutting tools. In the 1970s, polycrystalline diamond (PCD) was synthesized using high-pressure synthesis technology, solving the problem of the scarcity and high price of natural diamonds. During the machining of diamond cutting tools, edge grinding is required depending on the specific application.

[0003] However, existing edge grinding devices have the following drawbacks in practical use: Most existing edge grinding devices only have one clamping module, which means that when grinding diamond tools, one diamond tool must be ground and removed before the next diamond tool can be clamped and fixed, thus reducing the grinding efficiency of diamond tools. Summary of the Invention

[0004] In view of the technical problem that most existing edge grinding devices only have one clamping module, when grinding diamond tools, one diamond tool must be ground and removed before the next diamond tool can be clamped and fixed, thus reducing the grinding efficiency of diamond tools. This utility model provides an edge grinding device for PCD diamond tool processing.

[0005] The technical solution adopted by this utility model is: a grinding device for PCD diamond tool processing, including a worktable, a support frame and a grinding wheel grinder.

[0012] The beneficial effects of this utility model are: 1. This utility model, through an adjustment mechanism, allows a diamond tool to be moved out of the grinding area after one tool has been ground, and a tool to be ground to be moved into the grinding area. This enables the worker to remove the ground tool and clamp and fix another tool to be ground, thereby achieving continuous tool grinding and improving the grinding efficiency of diamond tools.

[0013] 2. Furthermore, this utility model, through the transverse moving mechanism and cylinder, can drive the grinding wheel grinder to move in multiple directions when grinding diamond tools, enabling the grinding wheel grinder to precisely grind the tools, thereby improving the grinding effect.

[0022] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, the tool shank is placed between the two clamping plates 26. Then, by rotating the bidirectional threaded rod 25, the two clamping plates 26 move in opposite directions, clamping and fixing the tool shank. Next, the transverse movement mechanism 3, the longitudinal movement mechanism 4, and the cylinder 15 are activated, causing the grinding wheel 16 to move in multiple directions for precise grinding of the tool. After grinding one tool, the electric telescopic rod 18 is activated, causing the lifting slide plate 19 to move upwards.

The locking block 23 disengages from the locking groove 22, allowing it to contact the stepper motor 20. The stepper motor 20 is set to limit the output of the stepper motor 20 and the rotating disk 21. Then, the stepper motor 20 is started, which drives the rotating disk 21 to rotate. The rotation of the rotating disk 21 drives several clamping mechanisms 6 to rotate. The rotation of the clamping mechanisms 6 drives the cutting tool to rotate, thereby moving the polished cutting tool out of the polishing area and moving the cutting tool to be polished into the polishing area. Then, the horizontal moving mechanism 3, the vertical moving mechanism 4 and the cylinder 15 are started again to drive the grinding wheel grinder 16 to polish the cutting tool to be polished. At this time, the operator can remove the polished cutting tool and clamp and fix a polished cutting tool to be polished, so as to realize continuous tool polishing operation and improve the polishing efficiency of diamond tools.
