Description
Technical Field
The utility model belongs to the field of steel pipe bending test machines, and relates to a steel pipe positioning device of a steel pipe bending test machine.
Background
The pipe bending test is carried out on a pipe bending test machine, and at present, the pipe bending principle of the commonly used pipe bending test machine is as follows: one end of the steel pipe is fixed by the positioning device, and the other end of the steel pipe is driven by the rotary working arm to rotate until the bending angle reaches a specified value. However, the existing positioning device is used for pressing and fixing the steel pipe through the cooperation of the bolt and the pressing plate, but the bolt is troublesome to screw and loosen in the fixing process.
Disclosure of Invention
The utility model provides a steel tube positioning device of a steel tube bending testing machine, which is positioned by means of an insertion mode.
In order to achieve the above purpose, the technical scheme adopted by the utility model is that the steel tube positioning device of the steel tube bending test machine comprises a positioning device body, wherein the positioning device body comprises a box body, the box body is hollow and is provided with two openings at two ends, two side-by-side roll shafts are rotatably connected in the box body, a roller is sleeved on the roll shaft, and the roller is arranged close to any inner side wall of the box body.
Preferably, the linear guide rail mechanism is fixedly connected with below the positioning device body and used for driving the positioning device to move, the linear guide rail mechanism comprises a supporting plate fixedly connected with the positioning device body, a sliding plate is fixedly connected with below the supporting plate, a nut seat is fixedly connected with below the sliding plate, a screw rod is in threaded connection with the nut seat, and a grab handle is fixedly connected with one end of the screw rod.
Preferably, a tabletop is arranged below the positioning device body, and a through hole for the supporting plate to pass through is formed in the tabletop.
Compared with the prior art, the utility model has the advantages and positive effects that,
according to the utility model, the steel pipe is inserted into the positioning device body, and the friction force generated when the roller is in contact with the steel pipe is small, so that the steel pipe is easy to pass through the positioning device body and more convenient than bolt fixing, and the linear guide rail mechanism is further arranged to drive the positioning device body to move, so that the position of the positioning device body is convenient to adjust. The utility model is convenient to use and is suitable for popularization and application.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings that are needed in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present utility model, and other drawings may be obtained according to these drawings without inventive effort to a person skilled in the art.
FIG. 1 is a schematic structural view of a steel pipe bending tester;
FIG. 2 is a schematic view of a steel pipe bending tester from another view;
in the above figures, 1, a positioning device body; 2. a through hole; 3. a grab handle; 4. and a roller.
Detailed Description
In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.
As shown in fig. 1 and 2, a steel tube positioning device of a steel tube bending test machine comprises a positioning device body 1, wherein the positioning device body 1 comprises a box body, the box body is hollow and is provided with two openings at two ends, two side by side roll shafts are rotatably connected in the box body, a roll wheel 4 is sleeved on the roll shaft, and the roll wheel 4 is arranged to be close to any inner side wall of the box body.
Specifically speaking, when running roller 4 pressed close to box body inside wall, another inside wall of box body is just kept away from in corresponding, inserts the box body with the steel pipe, and the steel pipe passes between running roller 4 and the long-range box body inside wall, and the produced frictional force is very little when running roller 4 and steel pipe contact, and the steel pipe of being convenient for passes to accomplish the location, convenient and fast.
In order to facilitate moving the positioning device body 1, the linear guide rail mechanism for driving the positioning device to move is fixedly connected below the positioning device body 1, the linear guide rail mechanism comprises a supporting plate fixedly connected with the positioning device body 1, a sliding plate is fixedly connected below the supporting plate, a nut seat is fixedly connected below the sliding plate, a screw rod is in threaded connection with the nut seat, one end of the screw rod is fixedly connected with a grab handle 3, and the sliding plate, the nut seat, the screw rod, the sliding block and the linear guide rail all belong to common structures in the linear guide rail mechanism, so the linear guide rail mechanism is not shown in the figure. Specifically, since the linear guide mechanism is provided, the position of the positioning device body 1 can be adjusted by shaking the grip 3.
For convenient use, a tabletop is arranged below the positioning device body 1, and a through hole 2 for a supporting plate to pass through is arranged on the tabletop.
The present utility model is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present utility model without departing from the technical content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
