Abstract
The invention discloses a tool holder which comprises a base, a chuck and a holding module, wherein a rotating shaft mounting groove is formed in the bottom of the base; the chuck is fixed at the top of the base; a fixing hole is formed in the chuck; the holding module comprises a fixed rod and a lock nut; the fixed rod passes through the fixing hole in the chuck and a through hole in a tool; the lock nut is screwed tightly on the fixed rod; and the tool is locked on the chuck by the lock nut. In the invention, the tool is stably fixed on the chuck through the holding module, the chuck is fixedly connected to the base, the rotating shaft mounting groove is formed in the base, a rotating shaft is fixed in the rotating shaft mounting groove, and the rotating shaft drives the base to rotate so as to drive the tool to rotate through the chuck.
Description
Technical field
The present invention relates to the machining equipment field, relate in particular to a kind of cutting tool gripper.
Background technology
In machining and engineering construction field, often can use circular cutter to mechanical part or construction material cut, sanding operation.Circular cutter is realized corresponding mechanical function by the toolframe driven rotary.In the prior art, circular cutter normally is fixed on the axle that is positioned at the toolframe center, drives circular cutter rotation by toolframe by axle.Because circular cutter contacts with metal material or stone material when work, the power that cutter bears is larger.Traditional toolframe only is connected and fixed at axle and the cutter in centre, so that the power of bearing on the axle is excessive, bending shaft, cutter bending or fixing loosening situation in use easily appear, these problems all can cause the fixedly appearance of cutter and toolframe loosening, so that the phenomenon of swing appears in cutter in rotary course.The swing of cutter can affect crudy, also can cause the accident when serious.
Summary of the invention
The present invention is intended to propose a kind of novel cutting tool gripper, firmly holding cutter.
According to one embodiment of the invention, a kind of cutting tool gripper is proposed, comprise base, chuck and clamp assemblies.The bottom of base has a rotating shaft mounting groove.Chuck is fixed on the top of base, has fixing hole on the chuck.Clamp assemblies comprises fixed bar and locking nut, and fixed bar passes fixing hole on the chuck and the through hole on the cutter, and locking nut is tightened on the fixed bar, and locking nut lock onto cutter on the chuck.
In one embodiment, locking nut is two, is tightened on respectively the up and down two ends of fixed bar.Cutter is fixed on the chuck top, and the locking nut of top screws from top to bottom, compresses cutter downwards, and the locking nut of below screws from bottom to top, upwards compresses chuck.
In one embodiment, the cross section of base is inverted trapezoidal.Installation shaft has bar section and head, and the diameter of head is greater than the diameter of bar section.The rotating shaft mounting groove comprises the first area that holds head and holds the second area of bar section, and the diameter of first area is greater than the diameter of second area.
Cutting tool gripper of the present invention by clamp assemblies with cutter firm be fixed on the chuck, chuck is fixedly connected on base, has the rotating shaft mounting groove on the base, rotating shaft is fixed in the rotating shaft mounting groove, rotating shaft drives the base rotation, rotates by chuck band cutter.
Description of drawings
Fig. 1 has disclosed the structure chart according to the cutting tool gripper of one embodiment of the invention.
The specific embodiment
With reference to shown in Figure 1, Fig. 1 has disclosed the cutting tool gripper 100 according to one embodiment of the invention.This cutting tool gripper 100 comprises base 102, chuck 104 and clamp assemblies 106.The bottom of base 102 has a rotating shaft mounting groove 103.Chuck 104 is fixed on the top of base 102, has fixing hole 105 on the chuck 104.Clamp assemblies 106 comprises fixed bar 107 and locking nut 108, and fixed bar 107 passes fixing hole 105 on the chuck 104 and the through hole 202 on the cutter 200, and locking nut 108 is tightened on the fixed bar 107, and locking nut 108 lock onto cutter 200 on the chuck 104.
In the embodiment shown in fig. 1, the quantity of locking nut 108 is two, and two locking nuts 108 are tightened on respectively the up and down two ends of fixed bar 107.Cutter 200 is fixed on the top of chuck 104.So the locking nut 108 of top is tightened on the fixed bar 107 from top to bottom, the locking nut 108 of top compresses cutter 200 downwards.The below locking nut 108 screw from bottom to top with fixed bar 107 on, the locking nut 108 of below upwards compresses chuck 104.So, by two locking nuts 108 up and down respectively fixed bar the screwing of two ends 107 about, from two ends up and down respectively with chuck 104 and cutter 200 clampings, thereby cutter 200 is fixed on the chuck 104.In one embodiment, chuck 104 is rounded, can offer several fixing holes 105 with even interval in the circumferential direction of the circle, and is corresponding, also can offer several through holes 202 with even interval on circular cutter 200, and the position of through hole 202 is corresponding with fixing hole 105.Clamp assemblies 106 comprises that fixed bar 107 and locking nut 108 are arranged in fixing hole 105 and the through hole 202, fixedly chuck 104 and cutter 200.
In the embodiment shown in fig. 1, the cross section of base 102 is inverted trapezoidal.Rotating shaft mounting groove 103 is positioned at the bottom of base 102.Installation shaft 300 has bar section 302 and head 304, and the diameter of head 304 is greater than the diameter of bar section 302.Rotating shaft mounting groove 103 comprises the first area 131 that holds head 304 and holds the second area 132 of bar section 302, and corresponding, the diameter of first area 131 is greater than the diameter of second area 132.First area 131 and head 304 have larger diameter so that rotating shaft 300 can be installed in the rotating shaft mounting groove 103 can not deviate from.
Cutting tool gripper of the present invention by clamp assemblies with cutter firm be fixed on the chuck, chuck is fixedly connected on base, has the rotating shaft mounting groove on the base, rotating shaft is fixed in the rotating shaft mounting groove, rotating shaft drives the base rotation, rotates by chuck band cutter.
