Abstract
The invention discloses a device for clamping a connecting shaft of a rolling machine, and the device comprises a connecting block. Cushion blocks are respectively disposed in upper and lower clamping grooves of the front end of the connecting block. The rear end of the connecting block is in transmission connection with a clamping hydraulic cylinder, and is also connected with two guide rods fixedly. The two guide rods are symmetrically disposed at two sides of the clamping hydraulic cylinder, and each guide rod passes through one pedestal equipped with a liner sleeve. The device can adjust the horizontal positions of the cushion blocks in an on-site installation process through the adjustment of nuts, guarantees that the central axis of the connecting shaft is consistent with the vertical central axis of a roller, meets the requirements of the push-in and pull-out of a flat head during the quick replacement of the roller, is simple in machining and manufacturing, and easily meets the precision requirements. The device is convenient to adjust in a process of installation and use.
Description
Technical field
The invention belongs to steel rolling equipment technical field, relate to a kind of extension shaft for rolling mill clamping device.
Background technology
In cold rolling workshop, milling train is visual plant wherein, the cold rolling of strip steel unit operation of rolling is the high-speed deformation process that sheet metal strip is occurred by the mutual extruding of roll, there is relative motion in thinning roll and the stocking surface of inevitably making again of stocking, roller surface in use may be scratched or cause fatigue, in order to ensure the surface quality of rolled strip and ensure the service life of roll, so need after using a period of time to change roll.Need power transmission shaft and roll to throw off when replacing roll, after more renewing roll, need power transmission shaft to be connected with roll.In order to the convenience that operates and quick milling train are provided with Quick roll-changing device, the propeller shaft tube be connected with roll need be carried out being fixedly clamped when roll change and locate, the spindle holder device difficulty of processing of current use is comparatively large, installation is inconvenient, scene adjusts difficulty, causes smooth cycle long impact of roll change to produce normally.
Summary of the invention
The object of this invention is to provide a kind of extension shaft for rolling mill clamping device, solve traditional spindle holder device difficulty of processing comparatively large, install inconvenient, positioning precision is high, on-the-spot adjustment difficulty, causes the problems such as the normal production of roll change cycle long impact.
The technical solution used in the present invention is, a kind of extension shaft for rolling mill clamping device, comprise contiguous block, a cushion block is separately installed with in two draw-in grooves up and down of contiguous block front end, contiguous block rear end and compression hydraulic cylinder are in transmission connection, contiguous block rear end is also fixedly connected with two guide posts simultaneously, and two guide posts are symmetricly set on compression hydraulic cylinder both sides, and each guide post is through the base being provided with lining.
Extension shaft for rolling mill clamping device of the present invention, is further characterized in that:
Each base is installed on the side of memorial archway by respective securing member.
The termination that each guide post exposes base is provided with adjusting nut and locking nut.
Beneficial effect of the present invention is, the gliding movement targeting structure of extension shaft for rolling mill clamping device, and existing rectangle closed-in construction is changed to two cylindrical guide bars; Processing is simple, positioning precision is high, in-site installation is easy to adjust, and the rhythm meeting fast roll changing requires, enhancing productivity ensures that the normal continuously of unit is produced.

In figure, 1. cushion block, 2. clamp, 3. bearing, 4. hydraulic cylinder, 5. adjust backing plate, 6. slide plate A, 7. slide plate B, 8. pressing plate, 9. contiguous block, 10. guide post, 11. bases, 12. compression hydraulic cylinder, 13. linings, 14. adjusting nuts, 15. locking nuts.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, Figure 2, the structure of prior art spindle holder device is, a cushion block 1 is separately installed with in two draw-in grooves up and down of clamp 2 end, respectively conjunction there is slide plate A6 and slide plate B7 in the above and below of clamp 2 and side, adjustment backing plate 5 is fixed with at the window inner side of clamp 2, be assembled into one with upper-part and respective fastener, be called movable frame; Pressing plate 8 and bearing 3 are installed on the transmission side of mill housing closing the firm banking be formed by connecting, movable frame under the driving of hydraulic cylinder 4 in the guide groove of firm banking transverse motion to achieve a butt joint the clamping of axle and the action of unclamping.
In above-mentioned structure, cushion block 1 move horizontally clamped position can only rely on increase and decrease adjustment backing plate 5 processing thickness realize, at the scene in installation process to its carry out processing adjust very inconvenient.If after the clamped position of cushion block 1 departs from the vertical center line of power transmission shaft, easily cause between roller palm and propeller shaft tube and occur jam, affect normal roller replacing operation.
As Fig. 3, spindle holder apparatus structure of the present invention is, comprise contiguous block 9, a cushion block 1 is separately installed with in two draw-in grooves up and down of contiguous block 9 front end, contiguous block 9 rear end and compression hydraulic cylinder 12 are in transmission connection, contiguous block 9 rear end is also fixedly connected with two guide posts 10 simultaneously, two guide posts 10 are symmetricly set on compression hydraulic cylinder 12 both sides, each guide post 10 is through the base 11 being provided with lining 13, and each guide post 10 is provided with adjusting nut 14 and locking nut 15 in the termination of exposing base 11, each base 11 is installed on the side of memorial archway by respective securing member.
The course of work of the present invention is,
By contiguous block 9, cushion block 1 and guide post 10 are connected into slip clamping part, this slip clamping part under the push-and-pull action of compression hydraulic cylinder 12 realizing clamping and release action by the base 11 being provided with lining 13, at the end thread place of guide post 10, adjusting nut 14 and locking nut 15 are installed, the horizontal level that can adjust cushion block 1 by adjusting nut 14 in installation process at the scene ensures that the center line of spindle is consistent with roll vertical center line, when meeting fast roll changing, homalocephalus pushing and pulling out, adjust suitable after locking nut 15 carried out locking avoid in use jumping.
Spindle holder device of the present invention, processing and manufacturing is simple, required precision easily ensures; Install and use in process easy to adjust.
