Description
Technical field
Machine tool field is the utility model is related to, especially a kind of center rest support device.
Background technology
In the field of machining of horizontal lathe or milling-boring machine, because diameter of work and length are excessive, individually by main spindle box
Clamped with the chuck jaws of tailstock, can not ensure that workpiece is stable, so as to influence machining accuracy, it is therefore desirable to which support meanss are propped up
Support.Existing support meanss, support the diameter range of workpiece small, regulation is inconvenient.
The content of the invention
In order to overcome the shortcomings of that existing horizontal lathe or the milling-boring machine machining accuracy when diameter of work and excessive length are low,
The utility model provides a kind of center rest support device, and the diameter range of center rest support device support workpiece is big, regulation side
Just, it is cost-effective so as to improve machining accuracy.
The technical solution of the utility model is：A kind of center rest support device, including centre frame base, the centre frame bottom
T-slot is provided with seat, two symmetrical supports are connected with T-slot, it is different upper that height is had on the support
Axis hole and lower shaft hole；Also include roller assembly, the roller assembly is fixed in one of axis hole of support by briquetting；Institute
The both sides for stating centre frame base are connected to left leading screw and right leading screw, and left screw is connected with left leading screw, is connected on right leading screw
There is right screw, the left screw and right screw are fixed by screws on two supports in left and right respectively.
The utility model has the advantages that：Due to taking such scheme, support can move along centre frame base or so
It is dynamic, and upper and lower axis hole is provided with support, so that it can be adapted to the workpiece of different-diameter, the range of work of expansion, carry
High manufacturing accuracy.And the device is simple to manufacture, and cost is cheap, the scope for supporting workpiece can be met, greatly save cost
With manufacturing time.

1- centre frames base in figure, 2- supports, 3- briquettings, 4- roller assemblies, the left leading screws of 5-, the left screws of 6-, the right leading screws of 7-,
The right screws of 8-, 9- upper shaft holes, 10- lower shaft holes.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Fig. 1 to Fig. 4, a kind of center rest support device, including centre frame base 1, roller assembly 4, the center
T-slot is provided with frame base 1, two symmetrical supports 2 are connected with T-slot, support 2 can move along T-slot, and pass through
T-slot bolt is fixed.Two described symmetrical configurations of support 2, support 2 have the different upper shaft holes 9 and lower shaft hole of height
10, it is upper shaft hole 9 at both sides of the edge wherein being lower shaft hole 10 at center.The roller assembly 4 is solid by briquetting 3
It is scheduled in one of axis hole of support 2, i.e., roller assembly 4 can be fixed in upper shaft hole 9, can also be fixed on lower shaft hole 10
It is interior.Because axis hole opening angle is smaller, to prevent roller assembly 4 from departing from, therefore with briquetting 3 by the shaft compression at the both ends of roller assembly 4.
The both sides of the centre frame base 1 are connected to left leading screw 5 and right leading screw 7, and left screw 6, right leading screw are connected with left leading screw 5
Right screw 8 is connected with 7.The left screw 6 is fixed by screws on the support 2 in left side, and right screw 8 is fixed on the branch on right side
On frame 2, so, rotational lead screw can drive screw to move, so as to drive support 2 to move left and right.
The support meanss can support a diameter of 500-900mm workpiece, when processing the workpiece of 900mm diameters, support 2
The both sides for being centrally disposed frame base 1 are fixed, and roller assembly 4 is placed in the lower shaft hole 10 of support；When processing small diameter
During workpiece, the nut of T-slot bolt is unclamped, rotates left and right leading screw with spanner, left and right screw is driven support 2 in centre frame base
Internally moved on 1, and roller assembly 4 is placed in the upper shaft hole 9 of support, to meet the needs of supporting workpiece, mix up position
Postpone and fasten T-slot bolt.
