Abstract
The utility model discloses a keyway processing frock, including the ring flange, trompil and aperture are greater than the handle of a knife external diameter in the middle of the ring flange, have the mounting hole that is connected with the main shaft on the ring flange, and there is the handle of a knife clamping device of a plurality of symmetries flange one side, and handle of a knife clamping device internal diameter is greater than the handle of a knife external diameter. By adopting the tool, a keyway can be machined by using general equipment such as a numerical control milling machine of a machining center, and higher machining precision can be obtained by using a common cutter handle through the symmetrical cutter handle clamping device.
Description
Technical Field
The utility model relates to the technical field of machining, specifically a keyway processing frock.
Background
In machining, special equipment such as a slotting machine and a planer is generally required to be used for machining the key groove, the key groove can be machined by axial movement of general equipment such as a machining center numerical control milling machine due to economic considerations, and the cutter handle can rotate or incline due to single-side stress during reciprocating movement.
Chinese patent with publication number CN203679392U discloses a keyway processing slotting tool for a vertical machining center, which comprises a main shaft positioning block connected with a main shaft of the machining center, a positioning connecting block is fixedly arranged on a tool shank, a tool shank positioning bolt is slidably arranged on the positioning connecting block, a jack matched with the tool shank positioning bolt is arranged on the main shaft positioning block, and an elastic part is arranged between the tool shank positioning bolt and the positioning connecting block. However, because the handle is stressed and fixed on one side, the handle is easy to loosen and rotate in the machining process, and the length of the positioning connecting block is fixed, so that the requirement on the installation distance between the main shaft positioning block and the main shaft is high.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a keyway processing frock that the precision is higher and it is more convenient to install, for solving above-mentioned technical problem, the utility model discloses a keyway processing frock includes the ring flange, trompil and aperture are greater than the handle of a knife external diameter in the middle of the ring flange, have the mounting hole that is connected with the main shaft on the ring flange, and there is the handle of a knife clamping device of a plurality of symmetries flange one side, and handle of a knife clamping device internal diameter is greater than the handle of a knife external diameter.
In a preferred embodiment, the tool shank clamping devices are two.
As a preferred embodiment, the tool shank clamping device is a clamping block corresponding to the position of the tool shank clamping groove, an internal thread through hole is formed in the clamping block, and the tool shank is clamped by using a jackscrew.
In a preferred embodiment, there are 6 mounting holes.
In conclusion, by adopting the tool structure, a common tool handle can be used, the situation that the tool handle is stressed and fixed on one side to rotate in the machining process is avoided, and the machining precision is improved.
Drawings
Fig. 1 is a schematic view of the present invention.
Wherein: 1. a flange plate; 2. mounting holes; 3. a tool shank clamping device; 4, a through hole with internal threads; 5. a main shaft; 6. a knife handle.
Detailed Description
The utility model discloses an utilize the axial motion of machining center numerically controlled fraise machine etc. general machining equipment main shaft to process the keyway.
The technical scheme of the utility model will be described in detail with the attached drawings as follows:
as shown in the figure, the key groove processing tool comprises a flange plate 1, wherein the flange plate 1 is provided with a central hole with the diameter larger than the outer diameter of a handle 6, the flange plate 1 is provided with a mounting hole 2 connected with a main shaft 5, one side of the flange plate 1 is provided with a handle clamping device 3, the inner diameter of the handle clamping device 3 is larger than the outer diameter of the handle 6, when the tool is used, the handle 6 is arranged in the main shaft 5 and is locked according to the original mode, a screw passes through the flange plate mounting hole 2 to tightly connect the flange plate 1 with the main shaft 5, the handle clamping device 3 is provided with a clamping block corresponding to the position of a clamping groove of the handle 6, the clamping block is provided with an internal thread through hole 4, a jackscrew passes through the internal thread through hole 4 to clamp and fix the handle 6 and prevent the handle 6 from rotating in the processing process, and it needs to explain that the tool is not limited by the utility model and can also use other shaft sleeve clamping structures of the handles commonly used in the mechanical field, at the moment, the radial direction of the main shaft 5 is firmly fixed, rotation cannot occur, and the tool shank 6 cannot incline because the tool shank clamping devices 3 are symmetrically arranged. Editing the machining program to make the main shaft 5 reciprocate axially without rotating, and starting the machining equipment to machine the key groove. If the pinion cutter for processing the gear is used, the utility model can also be used for processing the gear.
As a preferable mode, the number of the mounting holes 2 is set to 6, so that the flange plate 1 can be more stably fixed.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
