Abstract
A kind of open center rest micromatic setting.It mainly solves the problems, such as time-consuming and laborious when the big mariages bumper structure occupied space of existing lathe open center rest, adjustment.It is characterized by: central frame body (3) bottom is connected with double helix lead screw (4), double helix lead screw (4) both ends thread rotary orientation is opposite, it is wherein connected with by nut the wheel support that rolls left (2) on the left of lead screw (4), left wheel (1) is connected on the wheel support that rolls left (2)；Right nut is connected on the right side of the lead screw (4), right nut is externally connected to worm gear (7), worm screw (6) are connected on worm gear (7), and worm gear (7) one end connects right rolling wheel support (9), is connected with right idler wheel (8) on right rolling wheel support (9).Towards and away from movement while two rolling wheel supports can be realized by the rotation of single screw in the open center rest micromatic setting, space, easy to adjust, high reliablity are saved.
Description
Technical field
The utility model relates to machine tool field, specifically a kind of open center rest micromatic setting.
Background technique
Currently, being mostly both at home and abroad mariages rod structure for lathes open center rests such as heavy-duty engine lathe and roll lathes, respectively
The movement to rolling wheel support is realized by the double lead-screw on Rotation Center Rest, thus reach the support to different-diameter workpiece,
A rolling wheel support mobile first makes its idler wheel against excircle of workpiece when adjustment, then adjusts another rolling wheel support and urge the rollers against tightly
The workpiece other side, reaches supporting role.But this mariages bumper structure occupied space is big, when adjustment, needs to rotate mariages respectively
Thick stick spends time length, adjustment force insufficient.
Utility model content
When in order to overcome the mariages bumper structure occupied space of existing lathe open center rest big, adjustment it is time-consuming and laborious not
Foot, the utility model provide a kind of open center rest micromatic setting, the rotation which passes through single screw
Towards and away from movement while two rolling wheel supports can be realized, space, easy to adjust, high reliablity are saved.
The technical solution of the utility model is: a kind of open center rest micromatic setting, including central frame body, the centre frame
Body bottom is connected with double helix lead screw, and double helix lead screw both ends thread rotary orientation on the left of lead screw by nut on the contrary, wherein connected
It is connected to the wheel support that rolls left, is connected with left wheel on the wheel support that rolls left；It is connected with right nut on the right side of the lead screw, is connected outside right nut
It is connected to worm gear, worm screw is connected on worm gear, and worm gear one end connects right rolling wheel support, is connected with right idler wheel on right rolling wheel support.
The utility model has the following beneficial effects: can be achieved two by the rotation of single screw due to taking above scheme
Rolling wheel support adjusts a wherein side roller brackets by micromatic setting, rolling wheel support is allow to exist simultaneously towards and away from movement
It is moved freely on lead screw and achievees the purpose that idler wheel against excircle of workpiece.The device is easy to operate, easy to adjust, it can be achieved that micro
Adjustment is saved space, is reduced costs.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the A-A along Fig. 1.
1- left wheel in figure, 2- roll left wheel support, 3- central frame body, 4- lead screw, 5- micromatic setting, 6- worm screw, 7- worm gear,
The right idler wheel of 8-, the right rolling wheel support of 9-.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Fig. 1, Fig. 2, a kind of open center rest micromatic setting, including central frame body 3,3 bottom of central frame body
Double helix lead screw 4 is connected with by bearing, and the thread rotary orientation at 4 both ends of double helix lead screw is on the contrary, wherein 4 left side screw thread of lead screw
Place is connected with left nut, and nut top is fixed together with the wheel support 2 that rolls left, and is connected with left wheel 1 on the wheel support 2 that rolls left.Institute
It states and is connected with right nut on 4 right side screw thread of lead screw, right nut top is separately connected right rolling wheel support 9 and micromatic setting 5.It is described micro-
Adjusting device 5 includes worm gear 7, worm screw 6, and 7 sets of worm gear are connected on right nut, through screw thread with right nut, and 7 top of worm gear is connected with
Worm screw 6.Right idler wheel 8 is connected on right rolling wheel support 9.
For the open type center bearing bracket in adjustment, rotating threaded shaft 4 moves left and right rolling wheel support in central frame body 3, first allows
Then left wheel 1 adjusts micromatic setting 5 close to workpiece again.The method of adjustment of micromatic setting 5 are as follows: use spanner rotary worm 6, snail
Bar 6 drives worm gear 7 to rotate, and the rotation of worm gear 7 can drive right nut to be moved to the left, and right nut drives right rolling wheel support 9 to the left again
It is mobile, to make right idler wheel 8 by clamping of workpieces.During the adjustment, it is first close to workpiece surface if it is right idler wheel 8, can first adjusted
Micromatic setting 5 is mobile to the position far from workpiece centre right rolling wheel support 9, until left wheel 1 first comes to workpiece surface
By the rotation of single screw two rolling wheel supports can be achieved simultaneously towards and away from movement in the device, and when use can first allow
The wheel support 22 that rolls left abuts excircle of workpiece, then adjusts right rolling wheel support 9 with micromatic setting 5, allows right rolling wheel support 9 in lead screw
On move freely, achieve the purpose that idler wheel against excircle of workpiece.
