The present invention discloses a measuring tool for the cable bearing groove of a suspension bridge cable clamp and belongs to the bridge manufacturing engineering technical field. The measuring tool includes a first measuring plate and a second measuring plate; the second measuring plate is slidably stacked on the plate surface of the first measuring plate; the second measuring plate slides linearly between a first position and a second position; one surface of the first measuring plate, which is opposite to the second measuring plate, is provided with scale marks; and the scale marks are distributed along the direction of the linear slide of the second measuring plate. When the measuring tool is applied to measurement, when the second measuring plate is located at the first position, and the first side edge of the first measuring plate can abut against one side wall of the cable bearing groove; the sliding of the second measuring plate is adjusted, so that the second side edge of the second measuring plate can abut against the other side wall of the cable bearing groove; and therefore, the width of the cable bearing groove can be measured on the basis of an exposed scale mark. The position of the measuring tool in the cable bearing groove can be adjusted, and the second measuring plate is made to slide, and then, the width of the different cross-sections of the cable bearing groove can be measured quickly and accurately.

The invention, which relates to the testing fixture field, provides a go-no go gauge comprising a cylindrical section bar body. A first groove go end, a first groove no-go end, and a handle are formed successively from one end to the other end of the section bar body relative to a first radial direction of the section bar body; and a second groove go end and a second groove no-go end are formed successively at the A first groove go end and the first groove no-go end relative to a second radial direction of the section bar body. The two opposite side surfaces of the first groove go end and the two opposite side surfaces of the second groove go end are connected by an arc surface to form a circular hole go end; and the two opposite side surfaces of the first groove no-go end and the two opposite side surfaces of the second groove no-go end are connected by an arc surface form a circular hole no-go end. Therefore, an effect of one gauge with three purposes is realized and the go-no go gauge can be used conveniently. When the go-no go gauge is used for checking, head turning is avoided; the operation becomes convenient; the time is saved; the cost of the cylindrical section bar material is low and processing becomes convenient.

The invention relates to tungsten steel mainly comprising the raw materials: 10-20% of a bonding metal, 0.05-0.5% of a rare earth metal, 0.3-1% of an inhibitor, and the balance tungsten carbide, wherein the crystal particle size of the tungsten steel is in a range of 0.1-1 [mu]m. With adopting of a low speed wire cutting technology, the tungsten steel is made into a measuring block applied in a commutator contact chip measuring device; the measuring device includes a ruler frame, a fixed sleeve, a movable measuring rod and a microdrum; the movable measuring rod is arranged in the fixed sleeve; the fixed sleeve is fixedly connected with the ruler frame; the movable measuring rod passes through the ruler frame; the microdrum is arranged on the fixed sleeve; the measuring block is arranged between two ends of the ruler frame and is provided with a conical notch; an included angle of two side edges of a contact chip is equal to an included angle of the conical notch; the front end of the movable measuring rod is provided with a conical measuring head corresponding to the conical notch. The tungsten steel with excellent performance of hardness, strength, wear resistance and the like is made into the measuring block applied to the commutator contact chip measuring device, and the measurement precision is high.

The invention relates to a handling and / or layering apparatus (10) and to a method for forming layers of piece goods. Piece goods (14, 14a) are conveyed on a horizontal conveyor (16) to a grouping and / or layering station (12) having a manipulator (20). In one working cycle, the manipulator (20) picks up at least one piece of piece goods (14, 14a) and moves same into a defined relative target position and / or target orientation, in particular with respect to a layer of piece goods to be formed. The horizontal conveyor (16) upstream of the grouping and / or layering station (12) in the transport direction (18) of the piece goods (14, 14a) has at least one sensor device (24) for obtaining position data and / or dimension data and / or orientation data of the transported piece goods (14, 14a). From the obtained data, electronic output signals (26) are generated, which are processed in a controller (28). The controller (28) controls the movements of the manipulator (20) within the movement space (22) for the purposes of layering.

The present invention provides a control system, a control method thereof, and a computer-readable storage medium capable of shortening the tact time of measurement while suppressing vibration in profiling control. The present invention is a PLC system (SYS) having a displacement sensor (7), a driving device (30, 40) and a PLC (1). In the PLC system (SYS), the profiling control unit (162) of the PLC (1) is based on the measurement information (one-dimensional information) of the displacement sensor (7) from which measurement noise (noise information) has been removed by the filter unit (162c) and From the position information of the driving device (30, 40), the target position where the distance between the displacement sensor (7) and the object A becomes constant is calculated.
