Embodiment Construction
[0010] The following structural drawings further describe an embodiment of the present invention:
[0011] like figure 1 As shown, the resistive double-rod butt joint flatness detector is mainly composed of a probe 2, a housing 3, a sliding plate 5, a sliding wire resistance 6, a signal processor 8, a measuring rod 9, an insulating block 12, and a spring 13. The top of the body 3 is provided with an upper cover 7, and the housing 3 is symmetrically provided with two left and right measuring rods 9 whose heads extend out of the housing bottom plate. Guide rails 11 with grooves are respectively provided on the inner walls of the inner two sides, and slide blocks 4 fixed on the left and right measuring rods 9 are respectively arranged in the grooves of the guide rails 11. The slide blocks 4 move up and down along the guide rails 11, and the left and right sides A sliding wire resistance 6 is arranged between the two measuring rods 9, and the sliding wire resistance 6 is parallel...

The invention relates to a resistance type butted flatness detector with two measuring rods, which comprises a shell, an upper cover, a right measuring rod, a left measuring rod, a measuring head and a rail, wherein the rail is arranged on the inner wall of the shell; insulating blocks are respectively arranged on the right measuring rod and the left measuring rod, and sliding blocks moving alongthe rail are respectively arranged on the right measuring rod and the left measuring rod; a sliding resistor parallel with the right measuring rod and the left measuring rod are arranged between the right measuring rod and the left measuring rod; sliding blades which are respectively connected with the insulating blocks arranged on the right measuring rod and the left measuring rod are symmetrically arranged on two sides of the sliding resistor; two ends of the sliding resistor are fixed on an insulating fixed seat connected with the inner wall of the shell; and a signal processor for collecting and processing relative displacement signals of the two measuring rods is arranged on the upper cover. The invention can simultaneously measure two butted measured structural parts, the height difference of the detected surfaces of the measured structural parts can result in length change of the sliding resistor between the two sliding blades, voltage signals and a set value are compared by a voltage comparator, actuating signals are sent according to the comparison result, and whether the detection requirement is met is displayed through the lightening state of a green light emitting diode and a red light emitting diode.
Description
technical field [0001] The invention relates to a docking flatness detector, in particular to a resistance type double-measuring rod docking flatness detector used for the docking flatness detection of curved surfaces, planes, gyratory and other structural parts during the docking process. Background technique [0002] At present, most of the detection of the flatness of the butt joint adopts the profiling detection method, that is, the worker uses a straight board with a high flatness to compare whether the boards that are connected together are on the same plane. This detection method cannot guarantee accuracy, is labor-intensive, time-consuming and labor-intensive, and is not conducive to automated production. Another method that is used more is to use a measuring tool with a single measuring rod such as a dial indicator to measure the distance between two plates and a fixed measuring device. The operation process of this method is loaded down with trivial details, and e...
