Description

Counterweight iron semicircular cavity detection tool Technical Field The utility model relates to the field of detection tools, in particular to a counterweight iron semicircular cavity detection tool. Background The counterweight iron is a device (a storage battery is arranged in a middle cavity and can also provide a power source for the device) for providing a counterweight function on the universal power device, as shown in fig. 1, the counterweight iron is a cuboid workpiece with a cylindrical surface semicircular cavity, and is divided into an upper half and a lower half (an upper counterweight iron seat and a lower counterweight iron seat), the opposite surfaces of the upper seat and the lower seat are respectively provided with a cavity, the cavities are formed by a middle semicircular surface and arc surfaces at two ends (the cavities can be simply called cylindrical surface semicircular cavities), at present, the whole profile of the cavity is difficult to be compared by using a detection plate, and the problem of low detection efficiency exists, so that the detection device is developed so as to detect the counterweight iron cavity more perfectly. Disclosure of utility model Based on the problems, the utility model aims to provide a counterweight iron semicircular cavity detection tool, which adopts the following technical scheme: The utility model provides a counterweight iron semicircular cavity detection tool which comprises a support, wherein positioning holes are formed in four corner positions of the support, a detection plate is arranged below the support, rotating shafts are arranged at two ends of the detection plate, the rotating shafts at two ends are coaxially arranged, the rotating shafts are rotatably connected to shaft seats, and the shaft seats are fixed on the support. Preferably, the support is H-shaped, avoidance openings are formed in two ends of the support, two ends of the detection plate extend upwards to the avoidance openings, and the shaft seat is fixed to the top surface of the support and corresponds to the avoidance openings. Preferably, a plurality of hollowed-out holes are formed in the middle of the support. Preferably, the detection plate comprises a middle straight line section, two ends of the straight line section are respectively provided with an arc section, and the rotating shaft is fixed at the upper end of the arc sections. Preferably, the outer edges of the straight line section and the arc-shaped section are provided with chamfers. Compared with the prior art, the utility model has the beneficial technical effects that: The utility model can comprehensively detect the outline of the semicircular cavity of the counterweight iron, improves the working efficiency, reduces the manufacturing cost and ensures that the inspection operation of the counterweight iron is more convenient and quicker.
