detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1 to 4, a tool sharpness detection device includes a base 1, a controller 2 arranged on the base 1, a clamping mechanism 3 arranged horizontally on the upper surface of the base 1, and a The pressing mechanism 4 that is arranged on the base 1 in the vertical direction, the tool sharpness detection paper clip 5 connected with the pressing mechanism 4; the clamping mechanism 3 includes a clamp 31 for clamping a tool to be detected, The pressing mechanism 4 includes a pressure sensor 41 arranged vertically downward.

The clamping mechanism 3 includes a drive motor 32 disposed inside the base 1 , and the drive motor 32 drives the clamp 31 to move through a connecting block 33 .

The pressing mechanism 4 includes two uprights vertically arranged on the upper surface of the base 1, a tooth bar 44 is connected between the two uprights and on the outside of the two uprights, the middle position of the tooth bar 44 is A pressure sensor 41 and a counterweight 42 are sequentially connected from top to bottom, and the lower end of the tooth bar 44 is connected with the knife sharpness detection paper clip 5 .

The knife sharpness detection paper clip 5 is connected with a first driving cylinder 52, and the first driving cylinder 52 is used to drive the knife sharpness detection paper clip 5 to move left and right.

A baffle 43 is arranged between the tooth bar 44 and the two uprights, and the pressure sensor 41 on the tooth bar 44 is connected to the baffle 43 .

The upper ends of the two columns are provided with a second driving cylinder 45, the end of the driving rod of the second driving cylinder 45 is connected with a hook 46, and the drag hook 46 on the second driving cylinder 45 corresponds to the baffle plate 43 shown. adaptation.

A fixing hole 51 is provided on the knife sharpness detection paper clip 5 . The clamping mechanism 3 includes two sets of clamps 31 .
