Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] In the description of the present invention, terms such as "upper", "lower", "left", "right", etc. indicating orientation, position and order are based on the orientation shown in the drawings, or are only for simplifying description, rather than indicating Or imply that the invention must have a specific orientation, position and sequence.

[0024] Such as figure 1 with figure 2 As shown, the large-diameter reaming drilling and sharpening tool of this embodiment includes a base 1, a supporting platen 2, a positioning push mechanism 3 and two clamping mechanisms 4, and the base 1 includes a steel bracket 11 and several lining plates 12. The shaped steel support 11 of example adopts channel steel to be welded into, supports on the ground. The backing plates 12 are welded and fixed on the top surface of the shaped steel bracket 11 at intervals, and the top surf...

Abstract

The invention discloses a large-diameter reamer blade grinding tool which comprises a base, a supporting table plate, a positioning and pushing mechanism and two clamping mechanisms. A T-shaped groove is formed in the longitudinal center of the supporting table plate, the two clamping mechanisms are vertically supported at one end of the supporting table plate in a spaced manner, and the positioning and pushing mechanism is fixed to the other end of the supporting table plate. A chip groove part of a large-diameter reamer is wrapped by a copper sheet and then is clamped and fixed in the two clamping mechanisms, one cutting blade of the end face of the large-diameter reamer is close to the peripheral face of a grinding wheel of a grinding machine, and one end of the positioning and pushing mechanism abuts against a center hole in the bottom of a handle part of the large-diameter reamer. The using method of the tool comprises the steps that (1), the large-diameter reamer is installed in the two clamping mechanisms; (2), the two clamping mechanisms and the positioning and pushing mechanism are installed on the base; and (3), three cutting blades of the cutting part of the large-diameter reamer are ground in sequence. The blade grinding quality and the blade grinding efficiency of the three cutting blades are remarkably improved, and the service life of the large-diameter reamer is prolonged.

Description

technical field [0001] The invention relates to a sharpening tool for a cutting tool, in particular to a cutting edge sharpening tool for a reaming drill with a large diameter (with a diameter of Φ30mm or more) and a use method thereof. It belongs to the technical field of metal cutting processing. Background technique [0002] The reamer is a commonly used tool in the cutting process. After long-term use, the edge of the reamer wears out, and it needs to be re-sharpened by a grinder before it can continue to be used. The quality of edge grinding directly determines the reaming quality of the reaming drill, and also determines the service life of the reaming drill. The end face of the reaming drill usually has three cutting edges at 120° to each other. For reaming drills with large diameters and lengths greater than 300 mm, it is difficult to grind the cutting edges. It is difficult to grind the three cutting edges to the same cutting cone surface. With a high level of ope...
