Description
Technical field
The utility model belongs to loom accessory technical field, especially relates to a kind of wobble component of cam link mechanism.
Background technique
Cam link mechanism mainly plays the effect of Movement transmit, can realize rotating, and swings, the compound movement in movement and plane or space.Cam swing arm in cam link mechanism of the prior art and the structure between cam comparatively simple, mainly realizing boss drives cam swing arm to swing regularly, swinging track is comparatively single, can not carry out the swing of different amplitude, can not carry out different amplitude combinations and regular swing.
In order to improve prior art, people have carried out long-term exploration, propose various solution.Such as, Chinese patent literature discloses a kind of upper rotor cam link mechanism [application number: CN00220369.3] of loom dobby device, comprises cam, on the main shaft of dobby device, and difference tool one boss and a cavity on respective wheel edge; One front rotary shaft, on the wallboard of dobby device; One top sword cam swing arm, is installed in the middle part of it on front rotary shaft, each tool roller in its top and the bottom, and roller contacts with described wheel edge respectively; One link arm, is installed on inside top sword cam swing arm; One pull-up cutter shaft, on the pull-up tool arm of hub setting in the cam double rocker mechanism of dobby device, tool broaching tool, broaching tool matches with the drag hook of dobby device; One broaching tool axle pivoted arm, is installed with on pull-up cutter shaft; A pair is in flakes short, two ends respectively with the pivot joint of pull-up cutter shaft pivoted arm link arm; Hook pressing plate shaft on one, hub setting is on wallboard; One fulcrum pivoted arm, is installed on hook pressing plate shaft; A pair length in flakes, two ends respectively with fulcrum pivoted arm and the pivot joint of top sword cam swing arm; Needle seat in flakes on one, is installed on hook pressing plate shaft; A pair needle is in flakes short, two ends respectively with the needle tool rest pivot joint of upper needle seat and dobby device needle lifting mechanism in flakes; One top sword seat, is installed on hook pressing plate shaft, tool pressing plate, and pressing plate is corresponding with the notch on described drag hook top.
Although such scheme to some extent solves the deficiencies in the prior art, realizing boss drives cam swing arm to swing regularly, but swinging track is still comparatively single, the swing of different amplitude can not be carried out, can not different amplitude combinations be carried out and regular swing.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and provide a kind of reasonable in design, structure is simple, is beneficial to the wobble component of the cam link mechanism carrying out different swing amplitude.
For achieving the above object, the utility model have employed following technical proposal: the wobble component of this cam link mechanism, be arranged between cam swing arm and cam mechanism, it is characterized in that, comprise the first pendulum pin be located on cam swing arm, the the second pendulum pin be fixed on cam swing arm is provided with between the first described pendulum pin, the setting and the first pendulum pin and the second pendulum pin stagger in the axial direction that the length of the second described pendulum pin is greater than the first pendulum pin, described cam mechanism comprises the first cam and the second cam, the path length of the second described cam is less than the first cam, the first described cam is provided with to be put the first boss that pin adapts and first puts pin and swing with the rotation of the first boss with first, the second described cam is provided with to be put the second boss that pin adapts and second puts pin and swing with the rotation of the second boss with second.Because the setting and the first pendulum pin and the second pendulum pin stagger in the axial direction that the length of the second pendulum pin is greater than the first pendulum pin, so the angle that the first pendulum pin rotates is large compared with the second pendulum pin, the amplitude of fluctuation of the first pendulum pin is comparatively large, and the amplitude of fluctuation of the second pendulum pin is less, can carry out the swing of different amplitude, in addition, the swing of the first pendulum pin and the swing of the second pendulum pin combine and can swing regularly, and the rule namely can carrying out different amplitude combinations swings, and global design is reasonable, structure is simple, practical.
In the wobble component of above-mentioned cam link mechanism, the side of described cam swing arm convexes to form convex surface, and the first described pendulum pin is located at the side of cam swing arm convex surface, and the second described pendulum pin is located at the opposite side of convex surface.First pendulum pin and the second pendulum pin stagger setting in the axial direction, adapt with the position of the first cam second cam.
In the wobble component of above-mentioned cam link mechanism, convex to form middle protuberance in the middle part of described cam swing arm to the second pendulum pin direction, the second described pendulum pin is arranged on middle protuberance.First pendulum pin and the second pendulum pin stagger setting in the axial direction, adapt with the position of the first cam second cam.
In the wobble component of above-mentioned cam link mechanism, the first described boss and the second boss to be positioned on same radial line and second to put pin when the first boss drives the first pendulum pin to swing and do not swing.When second boss drives the second pendulum pin to swing, first puts pin and does not swing, the interfere between the swing preventing different amplitude.
In the wobble component of above-mentioned cam link mechanism, the first described pendulum pin has the groove adapted with the first boss, be provided with one-way check structure in described groove and the first boss can not drive the first pendulum pin to swing through groove when the first cam counterclockwise rotate by circumference, when rotate clockwise by circumference for the first cam, by unidirectional barrier structure, the first boss is stopped that drive first is put pin and swung.Meet the needs of the situation of unidirectional swing.
In the wobble component of above-mentioned cam link mechanism, described one-way check structure comprises unidirectional baffle plate, described unidirectional baffle plate is connected with the cell wall of groove by coupling shaft, is provided with the block that can stop that unidirectional baffle plate rotates between described cell wall and unidirectional baffle plate.When the first cam clockwise rotate by circumference, the first boss is resisted against on unidirectional baffle plate, unidirectional baffle plate stop by block, thus drive the first pendulum pin to swing; When rotate counterclockwise by circumference for the first cam, unidirectional baffle plate pushed open by the first boss, the first pendulum pin can not be driven to swing, meet the needs of the situation of unidirectional swing.
Compared with prior art, the advantage of the wobble component of this cam link mechanism is: first, the setting and the first pendulum pin and the second pendulum pin stagger in the axial direction that the length of the second pendulum pin is greater than the first pendulum pin, so the angle that the first pendulum pin rotates is large compared with the second pendulum pin, the amplitude of fluctuation of the first pendulum pin is larger, the amplitude of fluctuation of the second pendulum pin is less, the swing of different amplitude can be carried out, in addition, the swing of the first pendulum pin and the swing of the second pendulum pin combine and can swing regularly, namely the rule can carrying out different amplitude combinations swings, global design is reasonable, structure is simple, practical.Second, first pendulum pin and the second pendulum pin stagger setting in the axial direction, adapt with the position of the first cam second cam.When 3rd, second boss drives the second pendulum pin to swing, first puts pin and does not swing, the interfere between the swing preventing different amplitude.4th, one-way check structure can meet the needs of the situation of unidirectional swing.
