Abstract
The utility model discloses a straight-through type tool holder, which is characterized in that a tool holder fixing seat is cylindrical, an inner thread is formed on the inner wall of the tool holder fixing seat close to the lower end, the tool holder is in a circular tube shape, the tool holder is assembled in the tool holder fixing seat, the upper end and the lower end of the tool holder respectively protrude out of the upper end and the lower end of the tool holder fixing seat, a spring and a tool holder locking nut are sequentially sleeved at the lower end of the tool holder, and the tool holder has the technical effects that: 1. the problem of cutter pressing when the main shaft grabs the cutter is solved; 2. quality accidents caused by the loss of the origin of coordinates due to the clamping of the main shaft are avoided; 3. and poor appearance of the milling groove edge caused by the pressing knife is avoided.
Description
Technical Field
The utility model relates to the technical field of milling cutter storage tool holders, in particular to a straight-through tool holder, and particularly relates to a mechanical connecting structure of the straight-through tool holder.
Background
The existing milling cutter holder adopts a spring type holder, an elastic piece is arranged in the holder and used for fixing and limiting a cutter, a clamping shell is easy to occur between the main shaft and the holder when the cutter is grabbed, after the clamping shell is clamped, the main shaft is easy to clamp, or a notch is formed in the edge of the milling cutter, so that bad edges of milling grooves can be possibly caused.
Disclosure of Invention
The utility model aims to provide a straight-through type tool apron, which redesigns the tool apron structure to enable the interior of the tool apron to be hollow and prevent the spindle from blocking the tool apron when the spindle grabs the tool. Overcomes the defects and shortcomings existing in the prior art.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the straight-through type tool holder, the tool holder fixing base is cylindric, form the internal thread on the inner wall that the tool holder fixing base is close to the lower extreme, still include a tool holder, the tool holder is cylindric, the tool holder is assembled in above-mentioned tool holder fixing base, the upper end and the lower extreme of tool holder are outstanding in the upper end and the lower extreme of tool holder fixing base respectively, a spring and a tool holder lock nut have been cup jointed in proper order to the lower extreme department of tool holder, this spring wire is by thin the thickness gradually, the wire of spring upper end is thinner than the wire of its lower extreme, form annular spring spacing step on the outer wall that is close to the middle section of tool holder, the spring upper end is supported this spring spacing step, the spring lower extreme is supported the tool holder lock nut, tool holder lock nut department is equipped with the external screw thread with above-thread complex, tool holder lock nut assembles in tool holder fixing base lower extreme, the lower extreme of tool holder is outstanding in tool holder lock nut distributes, tool holder is close to the outer wall department of upper end forms bellied annular spacing ring, tool holder fixing base is close to the inner chamber department of upper end forms with annular spacing ring complex annular spacing bead for spacing tool holder, the tool holder outer fringe department of fixing base upper end forms annular assembly spacing muscle.
The utility model discloses a straight-through type tool apron, which has the technical effects that: 1. the problem of cutter pressing when the main shaft grabs the cutter is solved; 2. quality accidents caused by the loss of the origin of coordinates due to the clamping of the main shaft are avoided; 3. and poor appearance of the milling groove edge caused by the pressing knife is avoided.

FIG. 1 is a schematic diagram of the structure of the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The utility model discloses a straight-through tool apron, which is different from the prior art in that: comprises a holder fixing seat 1, wherein the holder fixing seat 1 is cylindrical, an inner thread 2 is formed on the inner wall of the holder fixing seat 1 close to the lower end, the holder fixing seat also comprises a holder 3, the holder 3 is cylindrical, the holder 3 is assembled in the holder fixing seat 1, the upper end and the lower end of the holder 3 respectively protrude out of the upper end and the lower end of the holder fixing seat 1, a spring 4 and a holder lock nut 6 are sleeved at the lower end of the holder 3 in sequence, the steel wire of the spring 4 is gradually thickened from thin, the steel wire of the upper end of the spring 4 is thinner than the steel wire of the lower end of the spring 4, an annular spring limit step 5 is formed on the outer wall of the holder 3 close to the middle section, the upper end of the spring 4 props against the spring limit step 5, the lower extreme of spring 4 supports cutter holder lock nut 6, cutter holder lock nut 6 department is equipped with above-mentioned internal thread 2 complex external screw thread 7, cutter holder lock nut 6 assembles in cutter holder fixing base 1 lower extreme, the lower extreme of cutter holder 3 is outstanding in cutter holder lock nut 6 distribution, cutter holder 3 is close to the outer wall department of upper end and forms bellied annular spacing ring 8, cutter holder fixing base 1 is close to the inner chamber department of upper end and forms with annular spacing ring 8 complex annular spacing protruding muscle for spacing cutter holder 3, the outer fringe department of cutter holder fixing base 1 upper end forms annular assembly spacing muscle 9, the lower segment of cutter holder 3 forms conical tube 10, conical tube upper end diameter is greater than the lower extreme diameter.
In specific implementation, the straight-through type cutter holder is arranged on a cutter holder platform, a through hole matched with the shape of the straight-through type cutter holder is formed in the cutter holder platform, a limiting structure is formed between the annular assembly limiting rib 9 and the upper edge of the through hole, and longitudinal limiting is achieved on the straight-through type cutter holder. The milling cutter is arranged in the cutter holder from the upper end of the cutter holder, and the unequal-diameter spring can play a good role in buffering.
The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described above. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
