Description

Morse taper shank slotting tool puller

Technical Field

The utility model belongs to the knife puller field relates to a morse taper shank slotting tool knife puller.

Background

The Lebohel and Larsenhole gear shaping machines are respectively provided with a Morse third conical cutter handle, and when the gear shaping machine is used for gear shaping, a Morse conical cutter handle slotting cutter matched with the cutter handle is arranged in the cutter handle and is fastened by conical surface adsorption and axial cutting force in the gear shaping process. The mode has the advantages that the structure of the knife handle and the slotting tool is simple, and the installation is convenient; the disadvantage is that the blade cannot be easily pulled out after being pressed by the cutting force.

In order to pull out the slotting tool compressed by the cutting force, a field operator strikes the slotting tool cutter bar by a copper bar, and the slotting tool is pulled out by loosening the cutter bar in the cutter handle by utilizing the vibration principle.

However, this method involves a risk of damaging or reducing the accuracy of the slotting tool.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a Morse taper shank slotting tool puller.

In order to achieve the above purpose, the utility model adopts the following technical scheme to realize:

a Morse taper shank slotting tool puller comprises a clamping piece and a rotating piece;

one side of the clamping piece is provided with a U-shaped groove, the rotating piece is provided with a through hole, the inner wall of the through hole is in threaded connection with the outer wall of the clamping piece, the outer wall of the rotating piece is provided with an opening communicated with the first through hole, and the width of the opening is not less than the groove width d of the U-shaped groove;

wherein: d_min<d<D_max，D_minThe diameter of the end of the slotting tool cutter bar outside the cutter handle is the minimum value; d_maxThe maximum diameter of one end of the slotting tool cutter bar outside the cutter handle.

The utility model discloses further improvement lies in:

the anti-drop bolt is also included; the anti-release bolt is connected with the rotating piece through threaded holes formed in two sides of the opening of the rotating piece.

Also comprises a rubber pad; the rubber pad is connected with the inner wall of the U-shaped groove.

The utility model also comprises two handles; the first handle is connected with the clamping piece, and the second handle is connected with the rotating piece.

The first handle is connected with the clamping piece through a first inner hexagonal hole formed in the clamping piece, and the second handle is connected with the rotating piece through a second inner hexagonal hole formed in the rotating piece.

The clamping piece is made of 45 steel.

Compared with the prior art, the utility model discloses following beneficial effect has:

through set up U type recess on chucking spare, will pull out the sword ware through follow U type recess card in the slotting tool cutter arbor from the side, the circular arc diameter of U type recess is between the diameter maximum and the minimum of the one end that the slotting tool cutter arbor is located outside the handle of a knife, guarantees that U type recess can successfully block in the slotting tool cutter arbor, is unlikely to again to drop from the axial. By rotating the clamping piece and the rotating piece in opposite directions, the axial distance between the clamping piece and the rotating piece is increased under the action of the threads, and when the certain length is reached, the cutter rod of the slotting tool is extruded from the cutter handle. Adopt chucking spare and rotating member stack design, when the screw thread of the through-hole inner wall of rotating member and chucking spare outer wall meshed completely, the dead knife ware axial distance is little, under the condition that the usable space of slotting tool cutter arbor is little, use that still can be fine. And simultaneously, the utility model discloses simple structure, the installation and use of being convenient for, it is with low costs.

Further, set up and prevent taking off the bolt, prevent taking off the bolt and be connected with the rotating member, after the U type recess of chucking spare is gone into to the slotting tool cutter arbor card, guarantee through preventing taking off the bolt that the slotting tool cutter arbor can not follow the slippage in the U type recess.

Further, the rubber circle excircle and the laminating of U type recess inner wall guarantee that U type recess and slotting tool cutter arbor direct contact's part be soft contact for the protection cutter prevents to pull out the sword in-process cutter and is damaged or the precision is lost.

Further, set up two handles, it is less to solve the dead knife ware main part diameter through two handles, and the rotation of convenient rotating member and chucking spare is compared in the problem that manual rotation is more strenuous.

Furthermore, the clamping piece is made of 45 steel, so that the hardness is low, and the cutter is prevented from being damaged as much as possible in the cutter pulling process.
