Abstract
The utility model discloses a double-end screw comprising a shaft lever. Step shafts are arranged at two ends of the shaft lever; a left-hand screw thread is arranged on the outer wall of the step shaft at one end of the shaft lever, and a right-hand screw thread is arranged on the outer wall of the step shaft at the other end of the shaft lever; and two corresponding bayonets are arranged on the outer wall of the shaft lever respectively. The double-head screw is provided with forward and backward thread structures, is flexible and convenient in working, and greatly shortens the time for installing a cutter hitting structure, thereby improving the working efficiency and economic benefits.
Description
Technical field
The utility model relates to the forge a knife assembly of mechanism of machining center, is specifically related to a kind of double threaded screw.
Background technique
Machining center is called for short CNC, the high efficiency automated machine tool of being made up of machinery and numerical control system that is used in the manufacturing complex shapes workpiece.Machining center is the computer gong again, and machining center has tool magazine, has the automatic tool changer function, is to carrying out the numerical control machine tool of multiple operation processing behind clamping of workpiece.Machining center is the product of height electromechanical integration; Behind the clamping workpiece, numerical control system can be controlled lathe and select, changes cutter, automatic tool preset automatically, changes spindle speed, the amount of feed etc. automatically by different operations, can accomplish brill, boring continuously, mills, working procedures such as hinge, tapping; Thereby significantly reduced the aided process times such as clamping workpiece time, measurement and lathe adjustment; To the machining shape more complicated, required precision is higher, and the frequent part of variety renovation has good economic effect.
In order to satisfy the quick debugging requirement of cutter in the machining center, need on the knife striking cylinder mounting plate, double-threaded screw be installed, reach the purpose of flexible transfer knife striking cylinder height.
The model utility content
The utility model provides a kind of double threaded screw, for positive and negative silk structure, shortens the installation time of the mechanism that forges a knife.
The technological scheme of the utility model is following:
A kind of double threaded screw; Include axostylus axostyle, it is characterized in that: the two ends of said axostylus axostyle are respectively the step axle, and wherein the outer wall of the step axle of an end is provided with left-handed thread; The outer wall of the step axle of the other end is provided with right-handed thread, is respectively equipped with two corresponding bayonet sockets on the outer wall of said axostylus axostyle.
Described double threaded screw is characterized in that: have spanner to be stuck in two corresponding bayonet sockets on the said axostylus axostyle outer wall.
The beneficial effect of the utility model:
The utility model structure is the double threaded screw that has positive and negative silk structure, and it is convenient flexibly to work, and has shortened the installation time of the mechanism that forges a knife greatly, thereby has improved working efficiency and economic benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of double threaded screw includes axostylus axostyle 3; The two ends of axostylus axostyle 3 are respectively step axle 1; Wherein the outer wall of the step axle of an end is provided with left-handed thread 2, and the outer wall of the step axle of the other end is provided with right-handed thread 4, is respectively equipped with two corresponding bayonet sockets 5 on the outer wall of axostylus axostyle 3.
There is spanner to be stuck in two corresponding bayonet sockets 5 on axostylus axostyle 3 outer walls, so just can comes rotating shaft rod 3 by spanner, thus can the dissimilar mechanism that forges a knife of quick mounting.
Claims (2)
