Technical Field

The invention belongs to the technical field of grinding, and relates to diamond tool bit grinding equipment, in particular to a tool bit clamping system of the diamond tool bit grinding equipment.

Background

The diamond tip is the working body of the diamond cutting tool. One end part of the diamond tool bit is formed by sintering alloy powder, and the end surface is called as a tool face; the other end is made mainly of iron and this end surface is called the bottom surface.

The bottom surface of the diamond tool bit needs to be ground, so that the bottom surface is ensured to be matched with the connecting surface of the diamond saw blade matrix. In order to improve the efficiency of grinding the bottom surface of the diamond segment, the applicant has proposed a diamond segment bottom surface grinding machine (application publication No. CN 103331488A). The diamond tool bit is stored in the vibration disc, the vibration disc vibrates to convey the diamond tool bit to the first grinding mechanism, the first grinding mechanism grinds a bright surface on one end face of the diamond tool bit, and the bright surface is judged to be positioned on the bottom face or the tool face through the vision sensor; then placing the diamond tool bit on a pushing assembly, and then pushing the diamond tool bit into a clamp; and finally, grinding the bottom surface of the diamond tool bit flat by adopting a second grinding mechanism. The diamond tool bit bottom surface grinding machine has the problems of complex structure, high manufacturing cost, low processing efficiency, poor universality and the like.

The diamond tool bit of some models contains stickness material, and in the grinding diamond tool bit process, stickness material adheres on the wheel face of emery wheel, can influence the smear metal ability of emery wheel after the adhesion accumulation, and the method of solving this technical problem at present is the grinding face of cutting diamond tool bit many times, and then guarantees the smear metal volume.

The bottom plate 3b is also provided with a pneumatic clamp 3h and a second cylinder 3i, and the left clamping arm 3e and the right clamping arm 3f are fixedly connected with the two clamping arms of the pneumatic clamp 3h in a one-to-one correspondence manner; the pressure head 3c is positioned above the bottom plate 3b, the bottom plate 3b is rotatably connected with a lever 3j, the front end of the lever 3j is fixedly connected with the pressure head 3c, and a piston rod of the second cylinder 3i is connected with the rear end of the lever 3 j; the piston rod of the second cylinder 3i can extend and retract to enable the pressure head 3c to move up and down. In order to improve the clamping precision, the firmness and the stability of the diamond tool bit 11, a lower bracket 3k is arranged at the bottom of the tool bit clamping opening 3a, and the lower bracket 3k is fixedly connected with the bottom plate 3 b. This chip holder 3 is suitable for pushing the diamond chip 11 from the front side of the chip holder mouth 3 a.
