Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
- Fig. 3 refering to fig. 1, the utility model discloses a kind of platens of adjustable axis height, including turntable
10, bridge plate 20, tailstock 30 and bottom plate 40.Wherein, turntable 10 is used as dividing spindle, is fixedly connected on one end of bottom plate 40；Tailstock
30 are connected on the other end of bottom plate 40 by stretching screw 50 and holding screw 60；Bridge plate 20 is horizontally set on the upper of bottom plate 40
Side, one end of bridge plate 20 are fixedly connected with turntable 10, and the other end is fixedly connected with tailstock 30, for placing multiple works to be processed
Part.
It, may between tailstock rotation axis 80 and turntable rotation axis 70 in actual installation process refering to Fig. 4-Fig. 5
The problems such as shifting, is not coaxial, but offset is not too big.Refering to Fig. 6, when tailstock rotation axis 80 is rotated lower than turntable
When axis 70, by first unclamping stretching screw 50, then by holding screw 60 toward backspin, the end of holding screw 60 is held out against the bottom of at
The surface of plate 40；Since holding screw 60 with tailstock 30 is connected by internal screw thread, tailstock 30 is by vertically upward
Power, position height get a promotion.On the contrary, tailstock rotation axis 80 is higher than turntable rotation axis 70 if adjustment amount is excessive, then it is loose
Stretching screw 50 is opened, by the appropriate up rotation of holding screw 60.
As a preferred embodiment, the quadrangle of the bottom of tailstock 30 passes through stretching screw 50 and clamp screw respectively
Nail 60 is connected on bottom plate 40.By all laying stretching screw 50 and holding screw 60, fixed function on the quadrangle of tailstock 30
It can be more firm；Meanwhile height adjustment can be carried out respectively to four angles of tailstock 30, the adjustment of different location can be answered
Cooperation is closed, keeps fine tuning more accurate.
As a preferred embodiment, the centre-height of tailstock 30 is lower than the centre-height of turntable 10.Due to tightening
Screw 60 can make the elevated height of tailstock 30 and after adjusting excess the height of tailstock 30 can reduce, and realize readjustment；
But if the surface of tailstock 30 and bottom plate 40 closely compresses after installation, and tailstock rotation axis 80 is higher than turntable rotation axis
If 70, it is difficult to reduce the height of tailstock 30.Therefore during installation, the centre-height of tailstock 30 is arranged to be slightly less than turntable
10 centre-height keeps the space of the height-adjustable of the present embodiment bigger.
- Fig. 3 refering to fig. 1, as a preferred embodiment, the present embodiment further includes turntable connecting plate 90, turntable connects
Fishplate bar 90 is arranged between turntable 10 and bridge plate 20, and turntable 10 is fixedly connected by turntable connecting plate 90 with bridge plate 20.As turn
Fitting, by the way that turntable connecting plate 90 is arranged, convenient for the connection between turntable 10 and bridge plate 20.Specifically, turntable connecting plate 90
Section is class L shape.
As a preferred embodiment, the present embodiment further includes tailstock connecting plate 100, tailstock connecting plate 100 is arranged
Between tailstock 30 and bridge plate 20, tailstock 30 is fixedly connected by tailstock connecting plate 100 with bridge plate 20.As adapter, pass through
Tailstock connecting plate 100 is set, it can be convenient for the connection between tailstock 30 and bridge plate 20.Specifically, the section of tailstock connecting plate 100 is
Class L shape.
By being elaborated to above-described embodiment, it will be understood that the utility model, which passes through, unclamps stretching screw 50, then will
Holding screw 60 is tightened down, and tailstock 30 can be mentioned up relative to the position of bottom plate 40, reaches the height of adjustment central axis
Effect；By the height adjustment to a position of tailstock more than 30, the levelness of central axis can be made to be adjusted.By that will turn
The central axis of platform 10 and the central axis of tailstock 30 keep horizontal and coaxial, and bridge plate 20 will not rotate when rotating because of turntable
Axis 70 and tailstock rotation axis 80 be not coaxial and damage turntable 10 and tailstock 30, at the same can guarantee be placed on bridge plate 20 to
Processing part can accurately index positioning, improve the machining accuracy of product.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
