Detailed Description
For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings 1-6 and the accompanying examples.
With reference to fig. 1-6, the turning tool structure of the present embodiment includes a tool bar 1 having a blade groove 1a for inserting a blade; a locking lever 2 for fixing the blade in the blade groove 1 a; still be equipped with locking hole 1b on the cutter arbor 1, the position in blade groove 1a is located to locking hole 1b, the mobilizable one end of check lock pole 2 is worn to locate in locking hole 1b, still includes locking lever 3, locking lever 3 promotes check lock pole 2 eccentric activity in locking hole 1b with fixed blade.
According to the turning tool structure, the locking lever 3 pushes the locking rod 2 to eccentrically move in the locking hole 1b so as to fix the blade, the stress direction of the locking rod 2 is changed by adopting a lever principle, so that the force required on the locking rod 2 is transferred to the locking lever 3, and the problem of abrasion caused by the fact that the inner hexagon influenced by the structure is too small is solved by increasing the size of the inner hexagon on the locking lever 3; this sword structure cost is lower, long service life, and is not fragile, and it is more convenient to change the blade, and satisfies the requirement of processing to lathe tool cutter arbor intensity, can use current general blade on the market, does not need research and development special blade, and research and development cost is low, can get into the market very fast and use.
As an alternative of the utility model, a lever groove 1c is arranged in the cutter bar 1 along the length direction, the lever groove 1c is a groove from the cutter head to the cutter tail in the cutter bar 1, so that the locking lever 3 can be placed in the groove, the locking hole 1b is communicated with the lever groove 1c, the locking lever 3 can be movably assembled in the lever groove 1c, the locking lever 3 can be contacted with the end part of the locking rod 2, so that the locking lever 3 can push the locking rod 2 to eccentrically move in the locking hole 1b,
as an alternative of the present invention, the locking lever 3 is movably installed in the lever groove 1c by a thread fit manner, the locking lever 3 includes a push rod 31 and a locking rod 32, an inner hexagonal is disposed on an outer end surface of the locking rod 32, the push rod 31 and the locking rod 32 are connected together by a spherical structure in a relatively rotatable manner (for example, a spherical groove is disposed at an end of the push rod 31, and a ball matched with the spherical groove is disposed at an end of the locking rod 32), the spherical structure is designed to enable the lever to rotate while transmitting force, the locking rod 32 is in thread fit with the cutter arbor 1, an internal thread is disposed on an inner wall of the lever groove 1c near the tail end of the cutter arbor 1, a push groove 31a for embedding an end of the locking rod 2 is disposed on the push rod 31, so that the push rod 31 can control the resetting action of the locking rod 2 to facilitate the detachment and replacement of the blade, the specific installation process is as follows: firstly, the push rod 31 is matched with the locking rod 32 and then is assembled in the lever groove 1c, then the locking rod 2 and the blade are installed, the lower end of the locking rod 2 penetrates through the locking hole 1b and then extends into the lever groove 1c, and the push rod 31 is driven to synchronously move forwards by the rightward rotation of the locking rod 32 so as to push the youtiao 2 to be eccentric relative to the locking hole 1b, so that the blade is locked; when the locking rod 32 rotates leftwards, the push rod 31 is driven to move backwards synchronously, and the locking rod 2 is reset to release the locking of the blade; this lathe tool structure provides the locking force of locking lever 3 through helicitic texture, stability when can guaranteeing the blade cutting.
As the utility model discloses an alternative, blade groove 1a has certain inclination, because after 2 eccentric activities to the regulation state at the check lock lever, the blade can produce the skew of certain angle thereupon in order to adapt to the activity of check lock lever 2, through having certain inclination with blade groove 1a design, guarantees that the blade is in the same place with blade groove 1a laminating completely after fixed to guarantee turning angle, blade groove 1 a's inclination can adjust according to the design demand.
As the utility model discloses an alternative, in order to make the operating personnel adopt lever principle more laborsaving to promote the check lock pole 2 through locking lever 3, the length of locking lever 3 is three times of the length of check lock pole 2 and more than, in this embodiment, the length of locking lever 3 is six times of the length of check lock pole 2.
The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
