All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a screw rotor rotary device, and it can be solved among the correlation technique to the support effect ratio that great rotor played poor, and general producer can all design the not supporting rollers of equidimension according to the rotor of difference, the technical problem who wastes time and energy.

In order to solve the above problem, this application provides a screw rotor rotary device, include along controlling to two supporting component 1 of interval distribution, supporting component 1 includes base 11, along around to two support frames 12 and adjustment mechanism 14 of distribution, two support frame 12 rotates and sets up base 11, the upper end of support frame 12 is rotated and is connected with supporting roller 13, adjustment mechanism 14 includes pivot 141, two dwang 142 and connecting piece 143, two dwang 142 rotates respectively to be connected on two support frames 12, and the other end then rotates and sets up in pivot 141, the one end of connecting piece 143 is fixed on one of them support frame 12, and other end detachably installs another on support frame 12.

Two support frames 12 are rotatably installed on the base 11 through a rotating shaft, the two support frames 12 can be relatively close to or far away from the base 11, and a V-shaped structure is formed between the two support frames 12 and the base 11, so that the distance between the two support rollers 13 can be adjusted, and screw rotors with different sizes are supported.

It will be appreciated that in the present application, two support assemblies 1 are provided, so that when supporting the screw rotor, a total of four support rollers 13 support both ends of the screw rotor.

In this application, in order to make the support frame 12 keep fixed after rotating a certain position, be provided with adjustment mechanism 14, two dwang 142 rotates respectively and connects on two support frames 12, and the other end then rotates and sets up on pivot 141, the one end of connecting piece 143 is fixed on one of them support frame 12, and other end detachably installs in another support frame 12, after two support frames 12 opened a certain position, make connecting piece 143 installed fixed, and be in the state of straightening, then support frame 12 receives the tractive effect of connecting piece 143, can't continue outwards to rotate, conveniently rotates screw rotor this moment to make things convenient for the workman to deburr and oil screw rotor.

Preferably, the connecting member 143 is made of a steel wire rope, but other rope-shaped structures may be used, and the steel wire rope is not easily broken when a certain hardness is required.

One of the support frames 12 is provided with a mounting base 2, the mounting base 2 is provided with an opening 3 for the steel wire rope to pass through, the support frame 12 is further provided with a pressing mechanism 4, and the pressing mechanism 4 comprises a movably arranged pressing block 41 for loosening or abutting against the steel wire rope.

In specific implementation, one end of the steel wire rope is fixed on the support frames 12, the other end of the steel wire rope is in a free state, after the opening angles of the two support frames 12 are adjusted, the steel wire rope in the free state is pressed and fixed through the pressing block 41, and at the moment, the middle part of the steel wire rope is in a stretched state, so that the support frames 12 are limited to rotate outwards continuously.

Further, the pressing mechanism 4 further includes an inner hexagon screw 42, the inner hexagon screw 42 penetrates through the mounting base 2, the inner hexagon screw 42 is in threaded connection with the mounting base 2, and the inner hexagon screw 42 is rotatably connected with the pressing block 41.

The socket head cap screws 42 are rotated by a tool, so that the pressing blocks 41 can move, the steel wire ropes are loosened or tightly supported, the length of the steel wire ropes which need to be stretched is convenient to adjust, and therefore the steel wire ropes can adapt to different stretching angles of the two support frames 12, for example, when the stretching angles of the two support frames 12 are large, the steel wire ropes need to be pulled towards the middle, and when the stretching angles of the two support frames 12 are small, the steel wire ropes need to be pulled outwards.

Because the steel wire rope is generally cylindrical, in order to prevent the steel wire rope from sideslipping, the side wall of the opening 3 opposite to the pressing block 41 is inwards recessed, and the section of the recessed area is arc-shaped, so that the steel wire rope is convenient to place.

In order to realize centering, namely synchronous approaching or departing of the two support frames 12, the device further comprises a guide mechanism 5, the guide mechanism 5 comprises a fixed sleeve 51 and a movable sleeve 52, the fixed sleeve 51 is fixed on the base 11 along the vertical direction, one end of the movable sleeve 52 is fixed on the rotating shaft 141, and the other end of the movable sleeve 52 is movably arranged in the fixed sleeve 51.

Referring to fig. 2, when the two support frames 12 rotate outward, the rotating shaft 141 is driven to descend, and since the rotating shaft 141 is fixedly connected with the movable sleeve 52 and the movable sleeve 52 can only move along the fixed sleeve 51, the rotating shaft 141 is limited to only move along the vertical direction, so that the two support frames 12 are prevented from rotating in the same direction due to uneven stress when the screw rotors are placed.

In some embodiments, the base 11 includes a first base 111 and a second base 112, and the two support frames 12 are rotatably disposed on the first base 111;

the lower extreme of first base 111 is equipped with screw thread post 6, set up on the second base 112 with the mounting groove 7 of screw thread post 6 adaptation, threaded connection has nut 8 on the screw thread post 6, and in screw thread post 6 inserted mounting groove 7, rotatory nut 8 can make screw thread post 6 with mounting groove 7 relatively fixed.

By adjusting the relative position of the threaded column 6 and the mounting groove 7, the height can be adjusted to the most comfortable operating height of the operator, the work fatigue is reduced, and the efficiency is improved, but it can be understood that, after the proper operating height is adjusted, the rotating nut 8 moves towards the second base 112, and presses the second base 112, so that the positions of the first base 111 and the second base 112 are relatively fixed.

Referring to fig. 1, in the present application, two slide bars 9 are further included;

the second base 112 is provided with a slide hole matched with the slide rod 9.

The slide rod 9 can be fixed on the working table, and the distance between the two second bases 112 can be adjusted by moving the second bases 112, so that the slide rod can adapt to screw rotors with different lengths.
