AI Technical Summary
During the aluminum block rolling process, the linear displacement sensor is directly connected to the rolling rack, which easily causes offsets and affects the measurement accuracy. The maximum measurement stroke of the linear displacement sensor is limited, which may cause the lift and lower adjustment stroke to exceed the maximum measurement stroke of the sensor, and the measurement result cannot be measured or the measurement accuracy is low.
An auxiliary adjustment device for sensors is designed, including a pressing cylinder, a piston rod, a linear displacement sensor, a measuring rod, a spring, a probe, a stroke block and a connecting plate. The spring reset makes the probe always pinched in the pinch groove, and the measuring rod is lifted and lowered simultaneously, ensuring accurate measurement of stroke.
By adding the design of stroke blocks and arc-shaped top joint grooves, the shortage of the linear displacement sensor is avoided, the top joint stability and measurement accuracy are ensured, and the service life of the sensor is extended.

Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary adjustment device for a sensor. Background Art
[0002] Rollers are required in the rolling process of aluminum blocks, and the lifting and positioning of the rollers are required to limit the rolling thickness. The lifting drive of the rollers is generally completed by pressing the cylinder, and the lifting stroke monitoring of the rollers is generally completed by linear displacement sensors. However, the probe is directly connected to the roller mounting frame, which is prone to offset and affects the measurement accuracy and the service life of the linear displacement sensor. Because the linear displacement sensor is generally set according to the standard, the length is fixed and limited, and it is easy for the lifting and lowering adjustment stroke to exceed the maximum measurement stroke of the linear displacement sensor. At this time, it will not be able to be measured or the measured result will be of low accuracy, which will affect the monitoring effect of the system. Utility Model Content
[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an auxiliary adjustment device for a sensor, which not only has a reasonable structure but also effectively ensures the travel monitoring accuracy of the roller.
[0004] In order to solve the above technical problems, the technical solution of the utility model is: it includes a pressing cylinder, the upper end of the pressing cylinder is connected to a pressing cylinder column via a piston rod, the top of the pressing cylinder column is connected to the frames at both ends of the roller to drive the roller to rise and fall, the side end of the pressing cylinder column is fixedly provided with a vertically arranged linear displacement sensor, the outer sleeve of the measuring rod of the linear displacement sensor is provided with a spring to facilitate its synchronous extension and retraction with the piston rod of the pressing cylinder, the end of the measuring rod is fixedly connected with a probe, the probe is connected to a travel block, the travel block is fixedly provided on the connecting plate and fixedly connected to the side wall of the pressing cylinder via the connecting plate.
[0005] Furthermore, the travel block and the probe top-joining side are provided with an arc-shaped top-joining groove concave inwardly, and the end of the probe is arc-joined in the top-joining groove.
[0006] Furthermore, a screw is fixedly connected to one end of the travel block away from the measuring head, and a through hole for the screw to pass through is opened on the connecting plate. After the screw passes through the through hole, it is tightened and fixed by a nut.
[0007] Furthermore, the pressing cylinder is symmetrically provided with two groups of frames respectively connected to the two sides of the roller, and two groups of corresponding linear displacement sensors and travel blocks are provided.
[0008] Compared with the prior art, the utility model has the following beneficial effects: by adding a stroke block, the situation of insufficient stroke of the linear displacement sensor can be avoided, and the top connection stability and measurement accuracy are guaranteed by cooperating with the probe and the top connection groove. The auxiliary adjustment device of the sensor has a simple structure and effectively guarantees the stroke monitoring accuracy of the rolling mill roller.

[0013] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.
[0014] like Figure 1~2 As shown, the auxiliary adjustment device of the sensor includes a pressing cylinder 1, the upper end of which is connected to a pressing cylinder column 15 via a piston rod 2, the top of which is connected to the frames 4 at both ends of the roller 3 to drive the roller to rise and fall, a vertically arranged linear displacement sensor 5 is fixedly arranged on the side end of the pressing cylinder column, a measuring rod 6 at the lower end of the linear displacement sensor is outer-circuited with a spring 7 to facilitate its synchronous extension and retraction with the piston rod of the pressing cylinder, a probe 8 is fixedly connected to the end of the measuring rod, and the probe is top-connected to a travel block 9, which is fixedly arranged on a connecting plate 10 and is fixedly connected to the side wall of the pressing cylinder via the connecting plate.
[0015] Furthermore, the travel block and the probe top-joining side are provided with an arc-shaped top-joining groove 11 facing inward, and the end of the probe is top-joined in the top-joining groove in an arc shape.
[0016] Furthermore, a screw rod 12 is fixedly connected to one end of the travel block away from the measuring head, and a through hole 13 for the screw rod to pass through is formed on the connecting plate. After the screw rod passes through the through hole, it is tightened and fixed by a nut 14.

The spring is stretched during the jacking and compressed during the descent. That is, the measuring rod can always rise and fall synchronously with the rising and falling of the frame, thereby ensuring accurate measurement of the stroke.

Anyone can derive other forms of auxiliary adjustment devices for sensors under the inspiration of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
