In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model comprises a base and a bracket; the upper side and the lower side of the inside of the base are respectively and rotatably connected with an upper toothed roller and a lower toothed roller, the upper toothed roller and the lower toothed roller are meshed with each other, a rotating shaft penetrates through the central axis of the lower toothed roller, the rotating shaft is fixedly connected with the lower toothed roller, and the rotating shaft penetrates through the left side wall and the right side wall of the base; the right end of the rotating shaft is arranged outside the base, and the right end of the rotating shaft is fixedly connected with a lower rotary table; the outer wall of the right end of the rotating shaft is in threaded fit connection with a pressing cylinder, and the pressing cylinder is sleeved at the right end of the rotating shaft; the handle is arranged on one side of the pressing cylinder, the support is triangular, the upper part of the support is one side of the triangle, and the lower part of the support is one corner of the triangle; the lower extreme of support links to each other with last fluted roller upper portion is fixed, the inside rigid coupling of upper end of support has the sleeve, the inside slip links to each other about the telescopic is connected with the slide bar, the top fixed connection square plate of slide bar, square plate and recess sliding connection, the recess is at the sleeve inner wall, the below end rotation of slide bar is connected with movable gyro wheel, and the bolt runs through sleeve upper portion and square plate, the outer wall top and the sleeve rotation of bolt link to each other, the outer wall top and square plate threaded connection of bolt, the top end rigid coupling of bolt has the carousel.

The right end outer wall of the pressing cylinder is provided with a bulge vertical to the outer wall of the pressing cylinder, and the bulge is abutted against the outer wall of the base.

The left and right sides of the lower part of the inner wall of the bracket are respectively and rotationally connected with fixed idler wheels, and the left and right fixed idler wheels are symmetrically arranged.

The utility model has the beneficial effects that: the utility model relates to a centering clamp which can be rotated by an angle according to the requirement. This facilitates the machining of the component.

Drawings

FIG. 1 is a schematic view of the front side of the present utility model;

FIG. 2 is a rear side partial cross-sectional view of the present utility model;

fig. 3 is a schematic view of the structure of the sleeve in the present utility model.

In the figure: 1. the device comprises a base, 2, a support, 3, a lower toothed roller, 4, an upper toothed roller, 5, a pressing cylinder, 6, a lower rotary table, 7, a fixed roller, 8, an upper rotary table, 9, a movable roller, 10, a bolt, 11, a sleeve, 12, a slide bar, 13, a handle, 14, a rotary shaft, 15, a square plate, 16, a groove, 17 and a bulge.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

referring to fig. 1-3: when the clamp is needed to be used, a user can put the whole equipment at the corresponding platform, and when the clamp is used, a pipe structure to be clamped is put between the fixed roller 7 and the movable roller 9, and the fixed roller 7 plays a role in supporting the pipe; then, the user can make the upper turntable 8 drive the bolt 10 to rotate by rotating the upper turntable 8 so as to drive the slide bar 12 and the movable roller 9 to move downwards, and the movable roller 9 and the fixed rollers 7 at two positions are utilized to realize centering clamping and fixing of the pipe. After the clamping and fixing are completed, a user can rotate the pressing cylinder 5 and separate the outer wall of the base 1 as required by rotating the handle 13, rotate the lower rotary table 6, enable the lower rotary table 6 to drive the upper toothed roller 4 to rotate through the lower toothed roller 3, drive the support 2 and the pipe to rotate through the upper toothed roller 4, so that the requirement of angle adjustment after clamping by the clamp is met, and after the rotating adjustment of the support 2 and the pipe is completed, the pressing cylinder 5 is screwed through the handle 13, the bulge 17 and the outer wall of the base 1 are abutted tightly, further the rotation of the lower rotary table 6 is effectively limited, and the angle change caused by looseness of the rotating part of the lower rotary table 6 during the subsequent pipe processing is prevented.

The utility model relates to a centering clamp which can be rotated by an angle according to the requirement.
