The technical solution of the utility model:
The device of the electrodeless locking of circular shaft, it is fixed on the Rack Body, comprises T type clamp body, has the circular hole that the transmission circular shaft is installed, the adjustment groove that is communicated with circular hole on the described T type clamp body, and described circular hole is locked by lock-screw; It is characterized in that: the open type copper sheathing is installed in the described circular hole.
Further, the flat adjustment screw of adjusting transmission circular shaft and circular hole axiality that is provided with of described T type clamp body.
Further, described open type copper sheathing is installed in the circular hole by dog screw.
Further, described T type clamp body has the destressing hole in the end of adjusting groove.
Further, have ladder light slotted eye on described T type clamp body flat, it is fixed on T type clamp body on the Rack Body by cooperating with sunk screw.
Further, described ladder light slotted eye towards vertical with the transmission circular shaft.
Ladder light slotted eye of the present utility model can make T type clamp body do suitable moving, and by regulating lock-screw, the circular hole size is changed, and open type copper sheathing size also can change simultaneously.When screwing lock-screw, can make and adjust the groove size decreases, simultaneously, the circular hole size also diminishes, and open type copper sheathing size also diminishes; When unscrewing lock-screw, utilize the strain of material itself, make and adjust groove size restoration prototype, for this reason, the circular hole size also restPoses, and open type copper sheathing size also restPoses.For the ease of adjusting axiality and the gap between circular shaft and the circular hole, the spy is provided with four and adjusts screw, when screwing wherein one when adjusting screw, T type anchor clamps physical efficiency is carried out the rotation adjustment of certain angle, when reaching installation specification, just can screw four sunk screws, make itself and Rack Body location and installation correct.
Operation principle of the present utility model:
Earlier the open type copper sheathing is put into the circular hole of T type clamp body, copper sheathing is carried out correct locking positioning (locating hole in the open type copper sheathing outer surface) with dog screw.Again the preliminary pretension of T type clamp body (four sunk screw can not revolve tighter) on frame, and be enclosed within on the transmission circular shaft, axiality actual conditions according to circular shaft and copper sheathing, adjust four respectively and adjust screw, regulate to adjust in the screw, T type clamp body can be done down and rotatablely moves around circular shaft, when adjusting to needed axiality and gap, just can screw four sunk screws, itself and Rack Body are installed and fixed.
Adjust after the correct installation of screw, promptly can regulate lock-screw, in initial (not screwing lock-screw) state, the transmission circular shaft can not have frictional rotation in the copper sheathing of T type clamp body; In work (screwing lock-screw) state, the copper sheathing size also diminishes thereupon gradually, under the effect of frictional force, make the copper sheathing surface chucking transmission circular shaft of T type clamp body, thereby the transmission circular shaft can not rotate, thereby the ball screw assembly, that is connected on the transmission circular shaft can not be moved, reached the purpose of positioning and locking; When wanting travelling table, as long as unclamp lock-screw, under the effect of strain, the copper sheathing in the T type clamp body will return to initial position.Lead screw pair is rotated and the job requirement of locking thereby reach.
The beneficial effects of the utility model: easily manufactured, technology is simple, low processing cost, installation rapidly and accurately, adjust precision height, long service life.

The specific embodiment
With reference to Fig. 4-6, the device of the electrodeless locking of circular shaft, its be fixed on Rack Body 8 on, comprise T type clamp body 1, have the circular hole 2 that transmission circular shaft 9 is installed, the adjustment groove 3 that is communicated with circular hole 2 on the described T type clamp body 1, described circular hole 2 passes through lock-screw 5 and locks; In the described circular hole 2 open type copper sheathing 11 is installed.
The flat adjustment screw 10 of adjusting transmission circular shaft 9 and circular hole 2 axialities that is provided with of described T type clamp body 1.
Described open type copper sheathing 11 is installed in the circular hole 2 by dog screw 12.
Described T type clamp body 1 has destressing hole 4 in the end of adjusting groove 3.
Have ladder light slotted eye 7 on described T type clamp body 1 flat, it is fixed on T type clamp body 1 on the Rack Body 8 by cooperating with sunk screw 6.
Described ladder light slotted eye 7 towards vertical with transmission circular shaft 9.
Ladder light slotted eye 7 of the present utility model can make T type clamp body 1 do suitable moving, and by regulating lock-screw 5, circular hole 2 sizes is changed, and open type copper sheathing 11 sizes also can change simultaneously.When screwing lock-screw 5, can make and adjust groove 3 size decreases, simultaneously, circular hole 2 sizes also diminish, and open type copper sheathing 11 sizes also diminish; When unscrewing lock-screw 5, utilize the strain of material itself, make and adjust groove 3 size restoration prototypes, for this reason, circular hole 2 sizes also restPose, and open type copper sheathing size 11 also restPoses.For the ease of adjusting axiality and the gap between circular shaft 9 and the circular hole 2, the spy is provided with four and adjusts screw 10, when screwing wherein one when adjusting screw, T type clamp body 1 can carry out the rotation adjustment of certain angle, when reaching installation specification, just can screw four sunk screws 6, make itself and Rack Body 8 location and installation correct.
Operation principle of the present utility model:
Earlier open type copper sheathing 11 is put into the circular hole 2 of T type clamp body 1, carried out correct locking positioning (locating hole in the open type copper sheathing outer surface) with 12 pairs of copper sheathings of dog screw 11.Again T type clamp body 1 preliminary pretension (four sunk screw can not revolve tighter) on Rack Body 8, and be enclosed within on the transmission circular shaft 9, axiality actual conditions according to circular shaft 9 and copper sheathing 11, adjust four respectively and adjust screw 10, regulate to adjust in the screw 10, T type clamp body 1 can be done down and rotatablely moves around circular shaft 9, when adjusting to needed axiality and gap, just can screw four sunk screws 6, itself and Rack Body 8 are installed and fixed.
Adjust after the correct installation of screw 10, promptly can regulate lock-screw 5, in initial (not screwing lock-screw) state, transmission circular shaft 9 can not have frictional rotation in the copper sheathing 11 of T type clamp body 1; In work (screwing lock-screw 5) state, copper sheathing 11 sizes also diminish thereupon gradually, under the effect of frictional force, make the copper sheathing 2 surface chucking transmission circular shafts 9 of T type clamp body 1, thereby transmission circular shaft 9 can not rotate, thereby the ball screw assembly, that is connected on the transmission circular shaft 9 can not be moved, reached the purpose of positioning and locking; When wanting travelling table, as long as unclamp lock-screw 5, under the effect of strain, the copper sheathing 11 in the T type clamp body 1 will return to initial position.Lead screw pair is rotated and the job requirement of locking thereby reach.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
