Description
Technical field
The utility model relates to mechanical field, particularly a kind of prevent screw mandrel sagging device and lathe
.
Background technology
At present, in machinery long distance transmission process, general employing rack pinion structure, but the transmission accuracy of rack-and-pinion is poor.Adopt long screw transmission, can be sagging in the middle part of long screw, cause long screw to bend, long screw, in high-speed rotation, causes rotation not steady.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of device preventing screw mandrel sagging, to solve the sagging problem of long screw.
On the one hand, the utility model provides a kind of device preventing screw mandrel sagging, comprise bracing frame, lifting support, hydraulic cylinder, promotion guide rod, connecting plate, limited block, hydraulic cylinder is connected with promotion guide rod by connecting plate, promote guide rod to be connected with lifting support, bracing frame offers pilot hole, promotes guide rod and coordinate with pilot hole; Limited block is arranged on bracing frame, spacing for lifting support; Lifting support is provided with support wheel, and screw mandrel is positioned at above support wheel, and lifting support is provided with sensor block.
Further, promote guide rod and comprise two, two promotion guide rods are arranged side by side.
Further, sensor block comprises two, and two sensor blocks are arranged on the two ends of lifting support respectively.
Further, support wheel comprises two, and two support wheels are arranged side by side, the rotation of two support wheels and the rotation axis parallel of screw mandrel.
Further, in pilot hole, spacer is installed, promotes guide rod and coordinate with spacer.
In addition, the utility model additionally provides a kind of lathe, comprises the above-mentioned device preventing screw mandrel sagging.
The utility model provide a kind of prevent screw mandrel sagging device and lathe, when screw mandrel is sagging, lifting support holds up screw mandrel, support wheel support screw, and rotating together with screw mandrel.Lifting support is moved up and down by Driven by Hydraulic Cylinder, ensures the linearity of screw mandrel.Sensor block is for realizing automatic lifting, and after sensor block senses signal, hydraulic system is according to the action of this signal automatic hydraulic control cylinder, thus promotion lifting support moves up and down, and realizes lifting screw mandrel to ensure the linearity of screw mandrel.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the device schematic diagram that the utility model prevents screw mandrel sagging.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, the utility model is a kind of device preventing screw mandrel sagging preferably, and comprise bracing frame 5, lifting support 10, hydraulic cylinder 1, promote guide rod 3, connecting plate 2, limited block 6, promote guide rod 3 and comprise two, two promotion guide rods 3 are arranged side by side.Connecting plate 2 offers two holes, promotes guide rod 3 patchhole and fixed by nut.Hydraulic cylinder 1 is connected with connecting plate 2, promotes guide rod 3 and is connected with lifting support 10, bracing frame 5 offers two pilot holes, in two pilot holes, is provided with spacer 4, promotes guide rod 3 and coordinates with spacer 4.Offer the cavity to opening above support frame, lifting support 10 is positioned at cavity, and limited block 6 is arranged on bracing frame 5, the airtight a part of cavity of limited block 6, and limited block 6 moves up for placing restrictions on lifting support 10; Lifting support 10 is provided with two support wheels 9, and screw mandrel 8 is positioned at above support wheel 9, and two support wheels 9 are arranged side by side, the rotation of two support wheels 9 and the rotation axis parallel of screw mandrel 8.Lifting support 10 is provided with two sensor blocks 7.Two sensor blocks 7 are arranged on the two ends of lifting support 10 respectively.
In addition, the utility model additionally provides a kind of lathe, comprises the above-mentioned device preventing screw mandrel sagging.
The utility model provide a kind of prevent screw mandrel sagging device and lathe, when screw mandrel 8 is sagging, lifting support 10 holds up screw mandrel 8, support wheel 9 support screw 8, and rotates together with screw mandrel 8.Lifting support 10 is driven by hydraulic cylinder 1 and moves up and down, and ensures the linearity of screw mandrel 8.Sensor block 7 is for realizing automatic lifting, and after sensor block 7 senses signal, hydraulic system is according to the action of this signal automatic hydraulic control cylinder 1, thus promotion lifting support 10 moves up and down, and realizes lifting screw mandrel 8 to ensure the linearity of screw mandrel 8.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
