Abstract
The utility model discloses a rotary isolation mechanism applied to a feeding mechanism of a honing machine. The rotary isolation mechanism comprises an upper ejector capable of making an axial motion, a main shaft and a lower ejector capable of making an axial motion and a spinning motion in the main shaft, wherein a rigid spherical body is arranged at one end part of the upper ejector and can roll at the end part of the upper ejector, a supporting block is fixedly arranged at the end part of the lower ejector, a rigid planar body is arranged on the opposite side of the supporting block to the lower ejector, and the spherical body is horizontally tangent to the planar body. Since the interaction between the upper and the lower ejectors is in a mode of contact of the spherical body and the planar body, that is, in a mode of central point contact, and the rotary isolation mechanism is immersed in a lubricating oil during work, the frictional heat generated by motions is minimized, and the service life of the honing machine is prolonged.
Description
Technical field
The utility model relates to a kind of interrupter, relates in particular to a kind of rotation interrupter that is used for the honing machine feed mechanism.
Background technology
When honing machine carries out work; Between the feed mechanism and main shaft in motion process on the main shaft; Need be delivered on the lower push rod in the main shaft through the top power of upper ejector pin, and further promote the honing head push rod and make honing head expansion, realize the honing processing action feed mechanism.Feed mechanism generally is made up of hydraulic jack or feeding motor, can not rotate because of receiving oil pipe or cable, and main shaft must drive the lower push rod rotation at work, between last lower push rod, has violent relative motion again in the process of transmission top power like this.Common traditional settling mode does; Be employed in during the hydraulic jack feeding and add the dual thrust bearing in the cylinder to reduce friction; But this mode receives the restriction of oil cylinder interior diameter; Particularly on small oil tank, can't realize, and also adopt the mode that adds thrust bearing, this dual mode that spatial constraints of receiving and complicated disadvantage are generally all arranged mostly when adopting motorized feed.
The utility model content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of rotation interrupter, is applicable to the honing machine feed mechanism, and this mechanism is easy to be durable, the frictional heat that can reduce motion to greatest extent and produced, and do not receive spatial constraints.
The technical scheme that the utility model adopts in order to solve the problems of the technologies described above is:
A kind of rotation interrupter comprises upper ejector pin, the main shaft that can axially move and the lower push rod with spinning motion of can in main shaft, axially moving, and said upper ejector pin one end is provided with the rigid spheres that can roll in said upper ejector pin end; Said lower push rod end is installed with back-up block, and said back-up block lower push rod dorsad simultaneously is provided with the rigid plane body, and said spheroid and plane body level are tangent.
Horizontal points of tangency between said spheroid and the plane body, the central axis of upper ejector pin, the central axis of lower push rod and the central axis of main shaft coincide.
Said upper ejector pin one end is coniform, and said spheroid active card is located at said coniform end.
Said back-up block extends upward the formation oil groove around the lower push rod one side dorsad, and said rigid plane body is positioned at oil groove and said oil groove inner rim is provided with the sealing scraper ring.
Be provided with back-moving spring, said back-moving spring fixed cover is located at lower push rod near back-up block one end.
The useful technique effect of the utility model is: this mechanism will go up and be designed to spherosome and the contacted mode of plane body between the lower push rod; It is the mode of central point contact; And should rotate interrupter and be immersed in the lubricating oil and work; Reduced the frictional heat that motion is produced to greatest extent, the service life of having improved honing machine.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In conjunction with Fig. 1 the utility model is done further detailed description.
A kind of rotation interrupter comprises upper ejector pin 1, the main shaft 7 that can axially move and the lower push rod 5 with spinning motion of can in main shaft 7, axially moving, and said upper ejector pin 1 one ends are provided with the rigid spheres 2 that can roll in said upper ejector pin end; Said lower push rod 5 ends are installed with back-up block 8, and said back-up block 8 lower push rod 5 one sides dorsad is provided with rigid plane body 4, and said spheroid 2 is tangent with plane body 4 levels.
The central axis of the horizontal points of tangency between said spheroid 2 and the plane body 4, the central axis of upper ejector pin 1, lower push rod 5 and the central axis of main shaft 7 coincide.
Said upper ejector pin 1 one ends are coniform, and said spheroid 2 active card are located at said coniform end.
Said back-up block 8 extends upward the formation oil groove around lower push rod 5 one sides dorsad, and said rigid plane body 4 is positioned at oil groove and said oil groove inner rim is provided with sealing scraper ring 3.
Be provided with back-moving spring 6, said back-moving spring 6 fixed covers are located at lower push rod 5 near back-up block 8 one ends.
When upper ejector pin 1 is ejected forward by the power effect of feed mechanism top; Spheroid 2 contacts with plane body 4 top power effect is passed to lower push rod 5; Lower push rod 5 is motion forward in main shaft 7; And drive and to order the back-moving spring 6 that is sheathed on lower push rod 5 ends admittedly and receive the extruding of main shaft 7 and compress, thereby driving the honing lever motion that is mounted thereon, lower push rod 5 realizes advancing of honing head or expansion action; When honing head need be retreated in workpiece, slowly to retreat through feed mechanism pulling upper ejector pin 1, this moment, spheroid 2 separated with plane body 4, and back-moving spring 6 drives lower push rods 5 and in main shaft 7, retreats and reset, and makes spheroid 2 and plane body 6 realize that again some faces contact.
For the frictional heat that reduces to greatest extent to move and produced; And the service life of improving honing machine; Spheroid 2 all adopts ganoid Hardmetal materials with plane body 4, and the contact position of spheroid 2 and plane body 4 is immersed in the sufficient lubricating oil through sealing scraper ring 3 works.
