Abstract
A kind of three roller guiding mechanisms, it is characterized in that：By vibration output shaft, upper equilateral triangle support, upper directive wheel group, column group, lower directive wheel group, lower equilateral triangle support composition.Upper equilateral triangle support, lower equilateral triangle support and column group are rigidly connected integrally, column group is made up of the upper equilateral triangle support of connection and three root posts at lower each side midpoint of equilateral triangle support triangle, upper directive wheel group is made up of three rollers for being provided with rolling bearing respectively with lower directive wheel group, every group of three directive wheels are installed in the same level height of column group, and three directive wheels are uniformly distributed by 120 ° of circumferencial directions for being spaced in vibration output shaft.Present invention employs three roller clamp cylinders vibration pto modes are distributed uniformly and circumferentially, the rolling for realizing vibration output shaft is oriented to.Compared with prior art, it is small with rubbing, it is not easy to wear, process, manufacturing cost low advantage low with matching requirements.
Description
Technical field：
Invention is related to a kind of three rollers guiding mechanism, belongs to auto parts vibration test technical field.
Background technology：
The guider of auto parts vibration mechine vibration output shaft is usually to use form of sleeve, because sleeve is with shaking
Dynamic output shaft is sliding friction, and frictional force is big, easy to wear, and processing and assembling requires high, and manufacturing cost is high.According to static pressure
Although bearing guides friction is small, not easy to wear, difficult in maintenance, the easy seepage of fluid, manufacture and use cost are all very
It is high.
The content of the invention：
Invention is related to a kind of three rollers guiding mechanism, mainly solves existing auto parts vibration mechine vibration output spindle guide
The frictional force existed to device is big, easy to wear, and processing and assembling requires high, the high technical problem of manufacturing cost.Invent and be
Solve the above problems and adopt the technical scheme that：A kind of three roller guiding mechanisms, by vibration output shaft, upper equilateral triangle branch
Frame, upper directive wheel group, column group, lower directive wheel group, lower equilateral triangle support composition.Upper equilateral triangle support, lower equilateral triangle
Support is rigidly connected integrally with column group, and column group is each by the upper equilateral triangle support of connection and lower equilateral triangle support triangle
The three root posts composition at side midpoint, upper directive wheel group is with lower directive wheel group respectively by three roller groups for being provided with rolling bearing
Into every group of three directive wheels are installed in the same level height of column group, and three directive wheels are spaced in vibration by 120 °
The circumferencial direction of output shaft is uniformly distributed.Due to equilateral triangle self-centering action, make the axis of vibration output shaft by it is lower just
Triangular supports, upper equilateral triangle support is positioned, after equilateral triangle support is fixed up and down, and vibration output shaft can just lead to
Directive wheel group is realized to roll and is oriented to above and below crossing, and avoids positioning.Invention employs above-mentioned two rows along vibration output shaft circle
Circumferential direction is uniformly distributed three rollers and clamps the modes of vibration output shafts carries out vibration output shaft and is oriented to, it is to avoid crosses and positions, real
The rolling for having showed vibration output shaft is oriented to, compared with background technology, small with rubbing, not easy to wear, processes low with matching requirements,
The low advantage of manufacturing cost.
Brief description of the drawings：
Fig. 1 is the structural representation of invention.
Fig. 2 is Fig. 1 left view.
Fig. 3 is Fig. 1 top view.
Embodiment：
The invention is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, a kind of three rollers guiding mechanism in the present embodiment, including vibration output shaft (1),
Upper equilateral triangle support 2, upper directive wheel group 3, column group 4, lower directive wheel group 5, lower equilateral triangle support 6, upper equilateral triangle branch
Frame 2, lower equilateral triangle support 6 and column group 4 are rigidly connected integrally, column group 4 by the upper equilateral triangle support of connection and it is lower just
The three root posts composition at each side midpoint of triangular supports triangle, upper directive wheel group 3 is with lower directive wheel group 5 respectively by three installations
It is made up of the roller of rolling bearing, every group of three directive wheels are installed in the same level height of column group 4, three guiding
Wheel presses 120。The circumferencial direction for being spaced in vibration output shaft is uniformly distributed, and due to triangle self-centering action, exports vibration
The axis of axle 1 is positioned by lower equilateral triangle support 6, upper equilateral triangle support 2, will be fixed equilateral triangle support up and down
Afterwards, vibration output shaft 1 just can be realized to roll and is oriented to by directive wheel group up and down, and avoid positioning.It is small with rubbing, it is difficult
Abrasion, processes, manufacturing cost low advantage low with matching requirements.
