Mechanism 3 bottom is uncovered, threadeds with installing rack 2 and floating push-pull mechanism 3 in floating push-pull mechanism 3 top
Top is also by from the vertical pretightning force of jackscrew 9 on installing rack 2, the cam 4 bearing 10 by its both sides
It is internal that rotation is fixed on floating push-pull mechanism 3, and floating push-pull mechanism 3 and power transmission shaft are stretched out in camshaft 11 one end
5 connect, and power transmission shaft 5 is connected with the output shaft of motor 1 by gear train 12, and cutter proximity switch 8 is arranged
On installing rack 2 above power transmission shaft 5, cutterhead 6 bearing is arranged on cutterhead axis 7, and cutterhead 6 is positioned at
Below cam 4, indexing roller 13 is positioned at cam 4 bottom notch.
Owing to using floating push-pull mechanism, this camshaft bearing seat is floating type, adjusts bearing block with jackscrew and makes
Power transmission shaft and camshaft gap and balance, because not having benchmark, be difficult to measure, the most parallel, shadow
Ring cam and indexing roller linear contact lay, thus reduce transmission efficiency, cam card master can be made time serious, need dimension
Repair and could use.And owing to cam axial gap floating push-pull mechanism ensures, and screw, jackscrew position
Put mutability, can cause each dismounting all can be different.It addition, arrange floating push-pull mechanism, add zero
Number of packages amount, and then add the complexity of tool magazine system, it is not easy to detachable maintaining in the future.
Summary of the invention:
In consideration of it, be necessary that design is a kind of reliable, compact, failure rate is low and easy-to-dismount tool magazine cam divide
Degree mechanism.
A kind of tool magazine cam indexing mechanism, including: motor, installing rack, cam, power transmission shaft, cutterhead, cutter
Dish axis, cutter proximity switch, adjustment block；Wherein, motor, the installing rack other end are fixed in installing rack one end
Bottom is uncovered and has a vertical dividing plate that uncovered for installing rack portion is isolated into relatively independent chamber in the middle part of installing rack
Room, cam is rotated by the bearing of its both sides and is fixed on the uncovered portion of installing rack, camshaft one end stretch out dividing plate with
Power transmission shaft connects, and is provided with a ring shape adjustment block between the bearing at the camshaft other end its end and installing rack
For adjusting end-play, during installation, first give the thickness that then the certain pretightning force of bearing determines adjustment block,
Mixing up post gap never to change, power transmission shaft is connected with the output shaft of motor, and cutter proximity switch is arranged on transmission
On installing rack above axle, cutterhead bearing is connected on cutterhead axis, and cutterhead is positioned at below cam, indexing rolling
Wheel is positioned at cam bottom notch.
Preferably, tool magazine cam indexing mechanism also includes that zero-bit proximity switch, zero-bit proximity switch are arranged on biography
On installing rack above moving axis.Zero-bit proximity switch detection tool magazine every revolution sends a signal.
Preferably, power transmission shaft is connected with the output shaft of motor by gear train.
Preferably, motor is retarding braking motor.
Cam, by cancelling floating push-pull mechanism, is directly arranged on installing rack by this utility model, and to adjust
Monoblock ensure end-play make structure more rationally, simplify, owing to decreasing part and assembling quantity,
Assembly precision can be ensured by processing, improves reliability under not reducing product original precision premise,
And it is readily accessible.
Accompanying drawing illustrates:
Accompanying drawing 1 is the schematic cross-section of the tool magazine cam indexing mechanism of a width prior art.
Accompanying drawing 2 is the schematic cross-section of a tool magazine cam indexing mechanism of the present utility model.
