Abstract
The utility model relates to a straightening roll height detection device for a tube straightening machine, characterized in that: the detection device comprises a sensor bracket mounted on the straightening machine rack, a displacement sensor mounted on the sensor frame, a horizontal connection plate mounted on the upper end of the displacement sensor, a transfer rod connected with another end of the connection plate, wherein the transfer rod is mounted in a guide sleeve and the guide is mounted on the straightening machine rack and a compression spring is sleeved on the transfer rod at the upper end of the guide sleeve and the upper end surface of the transfer rod clings the lower end surface of the lifting roll seat. When the height of the lifting roll seat is adjusted, the follow-up between the transfer rod and the lifting roll seat is realized, thereby directly measuring the height of the straightening roll on the lifting roll seat. The straightening roll height detection device has advantages of simple structure, accurate detection, convenient use and greatly increased work efficiency.
Description
Technical field
The utility model belongs to the tube straightener for pipe technical field, particularly relates to a kind of smoothing roll height detecting device that is used on the tube straightener for pipe.
Background technology
The smoothing roll of tube straightener for pipe is installed on the roller seat, and wherein dance roller can be with the lifting of lifting roller seat, realizes height control, required recurvation amount of deflection when obtaining aligning tubing.The levels of precision of this recurvation deflection value directly determines the leveling effect of tubing, so the accuracy of dance roller height detecting device seems extremely important.Existing tube straightener for pipe dance roller height detecting device adopts rotary encoder more, and measuring method is the lifting distance that the rotating cycle of scrambler is converted to dance roller, belongs to indirect type and measures.Because there are all multifactor influences such as gap in kinematic train itself, makes that the accuracy of this indirect metering system is relatively poor relatively, can not reach optimal flattening precision in the production run.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, stable performance, accuracy high be used for smoothing roll height detecting device on the tube straightener for pipe.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of smoothing roll height detecting device that is used on the tube straightener for pipe, it is characterized in that: this pick-up unit comprises the sensor stand that is installed on the straightening machine frame, be installed in the displacement transducer on the sensor frame, the displacement transducer upper end is equipped with the web joint of horizontal positioned, the other end of web joint connects the transmission bar, transmitting bar is installed in the guide pin bushing, guide pin bushing is installed on the straightening machine frame, the upper end of guide pin bushing is transmitted on the bar and is set with compression spring, and the lower surface of lifting roller seat is close in the upper surface of transmitting bar.
Advantage and the good effect that the utlity model has are: because the sensor stand of the utility model on straightening machine frame, be installed in the displacement transducer on the sensor frame, the displacement transducer upper end is equipped with the web joint of horizontal positioned, the other end of web joint connects the transmission bar, transmitting bar is installed in the guide pin bushing, guide pin bushing is installed on the straightening machine frame, the upper end of guide pin bushing is transmitted on the bar and is set with compression spring, compression spring keeps when mounted and must install by pressure, guarantees that like this lower surface of transmission bar and lifting roller seat is close to.When the lifting roller seat carries out height control, can realize transmitting the servo-actuated of bar and lifting roller seat, thereby the height value that is installed in the smoothing roll on the lifting roller seat is directly measured; Therefore the utility model also have simple in structure, detect accurate, easy to use, and advantage such as increase work efficiency greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, straightening machine frame; 2, sensor stand; 3, displacement transducer; 4, web joint; 5, transmit bar; 6, guide pin bushing; 7, compression spring; 8, lifting roller seat.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1, a kind of smoothing roll height detecting device that is used on the tube straightener for pipe, comprise and be installed on the straightening machine frame 1 sensor stand 2, be installed in the displacement transducer 3 on the sensor frame 2, displacement transducer 3 upper ends are equipped with the web joint 4 of horizontal positioned, the other end of web joint 4 connects transmission bar 5, transmitting bar 5 is installed in the guide pin bushing 6, guide pin bushing 6 is installed on the straightening machine frame 1, the upper end of guide pin bushing 6 is transmitted on the bar 5 and is set with compression spring 7, compression spring 7 keeps when mounted and must install by pressure, guarantees to transmit bar 5 like this and is close to the lower surface of lifting roller seat 8.When lifting roller seat 8 carries out height control, can realize transmitting the servo-actuated of bar 5 and lifting roller seat 8, thereby the height value that is installed in the smoothing roll on the lifting roller seat 8 is directly measured like this; Therefore the utility model also have simple in structure, detect accurate, easy to use, and advantage such as increase work efficiency greatly.
Principle of work: driven by motor leading screw and when lifting roller seat 8 being adjusted up and down, because the effect of compression spring 7 makes that transmitting bar 5 remains relation of following up with lifting roller seat 8 by nut.Transmitting bar 5 drives displacement transducers 3 through web joint 4 again and stretches out with the lifting of lifting roller seat 8 or withdraw, its variable quantity is identical with the height control amount of lifting roller seat 8, therefore can accurately react the lifting value of lifting roller seat 8, thereby guarantee that steel pipe can provide accurate recurvation amount of deflection in the aligning process, guarantee flattening precision.
The above only is the preferable example of executing of the present utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all fall into technical scope of the present utility model.
