Automatic reaming device for center hole of circular saw blade

Abstract

The invention discloses an automatic reaming device for the center hole of a disc saw blade, and belongs to the technical field of metal saw blade processing machinery. The automatic reaming device comprises a base, a vertical drilling machine, a material feeding mechanical arm translation driving mechanism, a material receiving mechanical arm translation driving mechanism, a material feeding lifting mechanism, a material receiving lifting mechanism, a reaming saw blade carrying mechanism, a material feeding mechanical arm and a material receiving mechanical arm. The vertical drilling machine is provided with a drilling machine worktable and a reamer; the material feeding mechanical arm translation driving mechanism and the material receiving mechanical arm translation driving mechanism are arranged on the base and on the left end and the right end of the base in the length direction; the material feeding lifting mechanism and the material receiving lifting mechanism are arranged on the back side of the left end of the base and the back side of the right end of the base; the reaming saw blade carrying mechanism is arranged on the drilling machine worktable; the material feeding mechanical arm is in sliding fit with the upper part of the left end of the base and is in connection with the material feeding mechanical arm translation driving mechanism; the material receiving mechanical arm is in sliding fit with the upper part of the right end of the base and is in connection with the material receiving mechanical arm translation driving mechanism. The equipment input quantity is reduced, and the labor resource is saved; the operation safety of workers is ensured; the operation intensity is reduced; the reaming quality of the center hole of the disc saw blade is ensured, and flaws are eradicated; mechanized automatic reaming is realized, the environment of a workplace where the workers work is standard and orderly.

Description

technical field [0001] The invention belongs to the technical field of metal saw blade processing machinery, and in particular relates to an automatic reaming device for a center hole of a circular saw blade. Background technique [0002] Since the material, structure, use and working principle of the circular saw blade mentioned above are well known in the industry, for example, please refer to the Chinese invention patent application publication number CN1311089A (circular saw blade), publication number CN102975236A (a circular saw blade structure), authorized announcement number CN202517132U (a circular saw blade) and publication number CN102658568A (a new type of circular saw blade), etc., so the applicant will not repeat them. The reaming mentioned above refers to reaming the center hole of the circular saw blade with the reamer of the drilling machine (vertical drilling machine, the same below), which is called finishing in the industry. [0003] The common features o...

Problems solved by technology

There are at least the following technical problems to this reaming method of the central hole of the circular saw blade: one, due to low efficiency, it is difficult to meet the requirements of industrialized mass production, but if the vertical drilling machine is added, the investment in equipment will be increased, It also causes a waste of labor resources; secondly, because the workers are directly with the vertical drilling machine, especially by manually moving the circular saw blade to the workbench of the vertical drilling machine and moving away from the workbench, the safety of the workers is difficult to guarantee. Because on the one hand, the drilling machine has the risk of injuring the operator, on the other hand, the sharp alloy head cutting edge of the circular saw blade, that is, the sawtooth, is easy to hurt the worker's limbs such as fingers; A high degree of tension can easily lead to physical and mental exhaustion of the workers; four, because the workers operate manually, the quality of the reaming of the central hole of the circular saw blade is difficult to guarantee, because the quality of the reaming is not related to the experience, sense of responsibility, and Physical and emotional related; fifth, because the workers are directly with the vertical drilling machine, so the working environment is relatively harsh

[0005] Undoubtedly, if there is a kind of automatic reaming device that is reasonable in structure and can be matched with the vertical drilling machine to carry out automatic reaming to the central hole of the circular saw blade, then the above-mentioned technical problems can be effectively solved, for this reason the applicant has carried out Literature search found "a coordinate type saw blade base internal circular grinder" recommended by Chinese invention patent application publication number CN103894897A. Although this patent solution can fulfill the technical effect recorded in paragraph 0014 of its description to a certain extent, it uses Compared with the use of reamers, the grinding device has limited efficiency in grinding the center hole of circular saw blades, and all operations still need to be completed manually by workers, so it has no enlightening effect on completely solving the aforementioned technical problems
