Problems solved by technology

The sizing machine after sizing and cutting can also accurately measure the length of the steel plate, but it has the following disadvantages: the equipment is heavy in weight, complex in structure, large in investment, slow in speed, and cannot measure short dimensions such as length less than 1 meter due to the structure of sizing shears Left and right steel plates, etc.
The measuring roller can also measure the length of the steel plate, but it has the following disadvantages: the measuring roller and the steel plate are easy to slip, and the measuring length is unstable and inaccurate

Embodiment

[0023] Example: such as Figure 1 to Figure 6 As shown, the length measuring device of the present invention includes a fixed-length baffle 1, a front fixed bracket 2, a wire tension reel 3, a wire displacement sensor 4, a guide shaft 5, a positioning pin 6, a rear fixed bracket 7, a cylinder 8, a fixed Support 9, rotating sleeve 10, key 11, fixed support 12, second key 13, angle measurer 14, front fixed support 2, rear fixed support 7 and fixed support 9 are arranged on the frame, and guide shaft 5 is supported on the fixed support 2. The rear fixed bracket 7 and the fixed bracket 9 can rotate around their own axis, and the guide shaft 5 is provided with a positioning pin 6; the baffle plate 1 is set on the guide shaft 5 and slides with the guide shaft 5 through the key connected so that the baffle plate 1 can slide axially along the guide shaft 5, and can rotate together with the guide shaft 5 under the action of the key 11. The front fixed bracket 2 is provided with a back...

Abstract

The disclosed length measurement device for plate of moderate thickness comprises: a scale baffle, a front / back fixing support arranged on frame, and a guide shaft supported on former supports to rotate round self. Wherein, it arranges the baffle on the shaft to slide through a bond, and sets a staying displacement sensor on the front support. Compared with prior art, this invention is simple and free to structure limit, has high measurement precision, and can be used in wide application.

Description

technical field [0001] The invention relates to a device for measuring length, in particular to a length measuring device for medium and thick plates in the metallurgical machinery industry. Background technique [0002] The length measuring device, also known as the sizing machine, is widely used in metallurgical machinery and other industries to measure the precise length of the rolled piece transported by the roller table. Its function is to make the cut length of the rolled piece accurate. It is usually set in Such as cut to length for medium and heavy plates, cut to length for profiles. Generally speaking, the rolling piece transported by the roller table drives the sizing baffle on the length measuring device to move horizontally, and the length of the rolling piece is accurately measured through the wire displacement sensor, but the overall structure of the sizing machine is relatively complicated. [0003] At present, there are two ways to measure the length of the ...
