Height-adjustable universal fixture for measurement of externally-installed parts of digital cameras

Abstract

The invention discloses a height-adjustable universal fixture for measurement of externally-installed parts of digital cameras. The height-adjustable universal fixture comprises a base and is characterized by comprising an adjusting block, wherein a groove is arranged on the base, the shape of the bottom face of the adjusting block is the same as that of the groove, the adjusting block can be inserted inside the groove, and cushion blocks of different heights can be arranged between the adjusting block and the groove of the base. The groove comprises two upper groove bodies and a lower groove body, the lower groove body is arranged between the two upper groove bodies, the depth of the lower groove body is deeper than that of upper groove bodies, and the lower groove body and upper groove bodies form a step shape. By the aid of the height-adjustable universal fixture, the problems that different measuring fixtures are required to be designed to conduct fixation, a lot of design time is consumed, the cost of an enterprise is increased and the working load is greatly increased for safekeeping and maintenance of measuring fixtures due to complex shapes of externally-installed parts in digital cameras are solved, and the height-adjustable universal fixture is good in generality and capable of meeting measurement fixation requirements of externally-installed parts of digital cameras in different structures.

Description

technical field [0001] The invention relates to an equipment for inspecting the size of exterior parts in the manufacturing and inspection process of a digital camera, in particular to a height-adjusting universal jig for measuring the exterior parts of a digital camera. Background technique [0002] In the production process of digital cameras, the dimensions of exterior parts need to be measured one by one according to the requirements of the design drawings. During the measurement process, the parts need to be fixed in a horizontal plane, so as to ensure the accuracy and reproducibility of each data measurement. The exterior parts of digital cameras are complex in shape, and it is usually difficult to find a relatively large plane for fixing the fixing surface. However, there are also many parts that have a common feature. There are many small planes with certain height differences on the parts. These planes can be used However, these surfaces are relatively small, and th...

Problems solved by technology

[0003] In order to solve the complex shape of the external parts of the digital camera in the prior art, it is necessary to design different measuring fixtures for fixing, which consumes a lot of design time and increases the cost of the enterprise. At the same time, the storage and maintenance of these measuring fixtures also greatly increases the work. In order to solve the problem of quantity, the present invention provides a universal height-adjustable jig suitable for measuring the fixed requirements of digital camera exterior parts with different structures.
