Detailed Description

Spatially relative terms such as "above … …", "above … …", "above … …", "above", and the like, may be used herein for ease of description to describe the spatial relationship of one feature or characteristic to another feature or characteristic as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1 and 2, a digital display dynamometer calibrating device comprises a base 1, a support column 2, a locating sleeve 3, a support plate 4, a standard dynamometer 5, a standard cushion block 6, a cylinder 7, a slide block 8, a guide rail 9, a movable frame 10, a support block 11 and an adjusting screw 12; the utility model discloses a support structure, including the support post, guide rail, adjustable shelf, cylinder, guide rail, piston rod, movable shelf, cylinder, piston rod, the bottom is fixed respectively on the base, the rear side of backup pad is passed through the position sleeve and is fixed on the support post, the guide rail is two, and is vertical to be fixed the front side of backup pad, the rear side of adjustable shelf pass through the slider with guide rail sliding fit, the cylinder is fixed the upper portion of backup pad, its.

The supporting blocks are at least four and are uniformly fixed on the movable frame in parallel, and concretely, the side parts of the supporting blocks are provided with adjusting grooves 16 and are fixed with the movable frame through bolts. The upper portion of adjustable shelf is fixed with diaphragm 17, the standard dynamometer is fixed the leftmost side on diaphragm upper portion, and the interval is equipped with the fixed orifices on the violently, and the dynamometer 13 that awaits measuring passes the fixed orifices and locks through nut 14, the lower extreme of standard dynamometer with the top cooperation of supporting shoe, adjusting screw thread fastening is in the bottom of adjustable shelf, adjusting screw's lower extreme and the cooperation of the standard cushion that sets up at the base front portion. The standard dynamometer is a standard instrument, and the readings of other instruments to be measured are compared with the standard dynamometer so as to achieve the purpose of verification, and three devices can be verified at one time.

In order to reduce the wear of the measuring head at the lower end of the force measuring instrument, a gasket 15 is arranged at the top of the supporting block and corresponds to the lower end of the force measuring instrument.

When the device is used, the standard dynamometer is fixed on the leftmost side or the rightmost side of the transverse plate in advance, a plurality of fixing holes in the transverse plate are universal, other three dynamometers are arranged in the fixing holes and screwed down through nuts, because the length of a measuring head at the lower part of each dynamometer is different from time to time and the difference is not particularly large, in this case, a supporting block needs to be adjusted, the upper part of the supporting block is in contact with the measuring head of each dynamometer, and a plurality of the dynamometers need to be in contact, for example, the measuring head at the lower part of one dynamometer is shorter, the supporting block needs to be moved upwards for a distance, then a bolt penetrates through an adjusting groove for fixing, finally, an air cylinder is started, the air cylinder drives four devices to move downwards at the same time, an adjusting screw at the lowermost part can be pressed on the standard cushion block, a plurality of the dynamometers are, if the difference range is large, the internal spring needs to be disassembled and replaced, and if the difference range is within the allowable range, the internal spring does not need to be replaced.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
