Fig. 2 is an enlarged schematic cross-sectional view of the sleeve.

Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1-2, a tool detection fixture includes a chassis 10, wherein the chassis 10 can be horizontally fixed on a numerical control machine and rotated under the control of the numerical control machine.

The chassis 10 is provided with a bottom plate 11, the bottom plate 11 is provided with a detection station, the detection station is used for placing a cutter 90, the right side of the detection station is provided with a fixed blocking piece, the left side of the detection station is provided with a fixed movable blocking piece, the rear side of the detection station is provided with a fixed rear blocking piece, and the cutter 90 is stabilized on the detection station under the restraint of the three blocking pieces.

The fixed blocking piece is provided with two fixed columns 12, and the fixed columns 12 are fixed on the bottom plate 11.

The rear blocking member is a rear baffle 20, and the rear baffle 20 abuts against the rear end face of the cutter 90.

The movable blocking piece comprises a fixed table 30, a sleeve 33 is fixed on the fixed table 30, a sliding rod 31 capable of sliding along the sleeve 33 is arranged in the sleeve 33, one end part of the sliding rod 31 extends to the outer side from the sleeve 33 and is used for fixing a chuck 32, a pressure spring 36 is arranged between the other end part of the sliding rod 31 and the bottom surface of the sleeve 33, a strip-shaped channel 34 is arranged on the sleeve 33, a handle 35 is fixed on the sliding rod 31, and one end part of the handle 35 extends from the strip-shaped channel 34 to the outside of the sleeve 33.

Referring to fig. 1, in order to adapt to the length of the cutter, a slideway (not shown) is provided on the bottom plate 11, the back plate 20 can slide on the slideway, a screw hole (not shown) is provided on the bottom plate 11, the screw hole is internally threaded to match with a bolt 22, the bolt 22 penetrates from the bar-shaped hole 21 of the back plate 20, and the nut of the bolt 22 is pressed on the upper surface of the plate 20. Thus, the bolts 22 act as switches that control whether the tailgate 20 can slide on the slides.

For stability, the collet 32 is held in position between the two fixed posts 12.

The angles between the sleeve 33, the slide bar 31 and the bottom plate 11 are all acute angles, preferably 45 degrees. In this way, the force component of the pressure of the sleeve 33 in both directions can form a balance force with the reaction forces of the bottom plate 11 and the fixing column 12, respectively.

The working principle is as follows:

referring to fig. 1-2, during clamping, S1, the handle 35 is first held to slide leftwards (leftwards in fig. 2), so as to drive the slide rod 31 and the chuck 32 to slide leftwards, and compressed by the compression spring 36.

S2, placing the cutter 90 on the detection station, and enabling the rear end of the cutter 90 to contact the front end of the rear baffle 20.

And S3, finally, the handle 35 is released, the pressure spring 36 is reset, and the slide bar 31 and the clamping head 32 are brought to slide rightwards until the clamping head 32 is pressed on the workpiece 90.

At this time, the workpiece is clamped.

In step S2, if the length of the cutter 90 is too short or too long, the bolts 22 are loosened, so that the tailgate 20 can be slid to a proper position on the slideway, and the bolts 22 are tightened again.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
