Rotation, therefore, guide rod can not move left and right in the centreless grinding Superfinishing machine course of work, to make the central axis of swinging head
Presetting crank degree is kept to remain unchanged in stretching motion.It can be seen that the utility model guiding mechanism can be according to processing
Need to adjust the crank degree of the central axis of swinging head, and adjusting is simple to operate, and then can compensate it to a certain extent
He and the component of center axis connection of swinging head or the processing of structure and rigging error, so as to reduce entire swing head system
Processing cost.In addition, the utility model guiding mechanism structure is simple, reliable performance, wherein the adjustable offset mandrel to play the role of a nucleus
It holds as universal standard product, greatly reduces the difficulty of processing and manufacturing cost of the utility model guiding mechanism.
Preferably, the Limit Bearing and the adjustable eccentric bearing are symmetrical set and close in the guide rod two sides
The anchor ear.In this way, can avoid guide rod when the movement with the central axis of swinging head is slided from Limit Bearing and adjustable offset
Mandrel is skidded off and is lost to the restriction of the crank degree of the central axis of swinging head and mobile guide restriction between holding.Further
Ground, the Limit Bearing are fixed in the guide seats by clamping screw.In this way, using clamping screw by limit shaft
It holds and is fixed in guide seats, avoidable Limit Bearing position is unstable and influences its restriction effect to guide rod, into
And influence the stability of guiding mechanism.
Preferably, the guide rod further includes fixed section and linkage section, and the linkage section is located at the fixed section and institute
It states between guide section and connects the fixed section and the guide section.Further, the linkage section and the guide section are even
The angle that socket part position is formed is obtuse angle, and the linkage section is to the inclined of the swinging head.In this way, can both reduce production
The consumptive material of guide rod, but can influence to avoid environmental factor to guiding mechanism, improve the guide function and corner of guiding mechanism
The stability of angle attributive function.
Preferably, the fixed section is provided with buckle on the side of guide section, and the buckle is withheld in the anchor ear
Side wall on.It is further preferred that the central axis upright of the central axis of the buckle and the swinging head.In this way, connecting
When guide rod and anchor ear, it can use buckle and fixed section in guide rod limited, joint efficiency can be improved, and then improve and lead
To the installation effectiveness of mechanism.
In addition, the utility model also proposes a kind of centreless grinding Superfinishing machine, which includes above-mentioned any
A kind of guiding mechanism.
Detailed description of the invention
Fig. 1 is structural schematic diagram when the utility model guiding mechanism is mounted on swinging head.
Specific embodiment
In the following, the utility model guiding mechanism is described in detail in conjunction with Fig. 1.
As shown in Figure 1, the utility model guiding mechanism is mounted on the swinging head 1 in centerless superfinishing machines, the Guiding machine
Structure includes guide seats 21, Limit Bearing 22, adjustable eccentric bearing 23 and guide rod 24, wherein guide seats 21 pass through fixation
Bolt 25 is fixed on the outer wall of swinging head 1 of centerless superfinishing machines.Limit Bearing 22 and the installation of adjustable eccentric bearing 23 are solid
It is scheduled in guide seats 21.Guide rod 24 includes guide section 241, fixed section 242 and linkage section 243, and linkage section 243 is located at admittedly
Determine between section 242 and guide section 241 and is connected and fixed section 242 and guide section 241.The positioning end of guide rod 24 is being put by clip
Anchor ear 26 on the central axis 11 of dynamic head 1 is fixed on the central axis 11 of swinging head 1, remotely located end in guide rod 24
The outside wall parallel of guide section 241 and swinging head, and 241 holding of guide section between Limit Bearing 22 and adjustable eccentric bearing 23 simultaneously
It is slided between Limit Bearing 22 and adjustable eccentric bearing 23 with the movement of the central axis 11 of swinging head 1.Preferably, linkage section
243 with guide section 241 the angle that connecting portion is formed be obtuse angle, and linkage section 243 to the central axis 11 of swinging head 1 inclination.This
Sample, can not only reduce the consumptive material of production guide rod 24, but can influence to avoid environmental factor to guiding mechanism, improve Guiding machine
The guide function of structure and the stability of crank degree attributive function.Preferably, fixed section 242 is on the side of guide section 241
It is provided with buckle 2421, and the buckle 2421 is withheld on the side wall of anchor ear 26.Preferably, in buckle 2421 and swinging head 1
The central axis upright of mandrel 11.In this way, can use buckle 2421 to guide rod 24 when connecting guide rod 24 and anchor ear 26
Middle fixed section 242 is limited, and joint efficiency can be improved, and then improve the installation effectiveness of guiding mechanism.
In addition, Limit Bearing 22 and adjustable eccentric bearing 23 are symmetrical set and close to anchor ear 26 in 25 two sides of guide rod.
In this way, can avoid guide rod 24 when the movement with the central axis 11 of swinging head 1 is slided from Limit Bearing 22 and adjustable eccentric
It skids off and is lost to the restriction of the crank degree of the central axis 11 of swinging head 1 and mobile guide restriction between bearing 23.It is preferred that
Ground, Limit Bearing 22 are fixed in guide seats 21 by clamping screw 27.In this way, using clamping screw 27 by limit shaft
It holds 22 to be fixed in guide seats 21, avoidable 22 position of Limit Bearing is unstable and influences its restriction to guide rod 24
Effect, and then influence the stability of guiding mechanism.
When being oriented to using central axis of the utility model guiding mechanism to the swinging head in centreless grinding Superfinishing machine,
The two connection is set to form relatively-stationary entirety the center axis connection of guide rod and swinging head first with anchor ear, further according to processing
It needs the center axis rotation of swinging head to required crank degree, and the guide section holding of guide rod is made to be mounted on guiding bottom
Between Limit Bearing on seat and adjustable eccentric bearing.In this way, in the centreless grinding Superfinishing machine course of work, the center of swinging head
Axis rotates due to the blocking by Limit Bearing without side where normal direction Limit Bearing, while after adjusting adjustable eccentric bearing, being
Adjustable eccentric bearing is close to guide rod in the other side of guide rod, to make guide rod also without side where normal direction adjustable eccentric bearing
Rotation, therefore, guide rod can not move left and right in the centreless grinding Superfinishing machine course of work, to make the central axis of swinging head
Presetting crank degree is kept to remain unchanged in stretching motion.It can be seen that the utility model guiding mechanism can be according to processing
Need to adjust the crank degree of the central axis of swinging head, and adjusting is simple to operate, and then can compensate it to a certain extent
He and the component of center axis connection of swinging head or the processing of structure and rigging error, so as to reduce entire swing head system
Processing cost.In addition, the utility model guiding mechanism structure is simple, reliable performance, wherein the adjustable offset mandrel to play the role of a nucleus
It holds as universal standard product, greatly reduces the difficulty of processing and manufacturing cost of the utility model guiding mechanism.
