The invention relates to a parameter determination device for a cutter of a quadratic element image measurer. The middle part of a fixture base is adjustably connected with a cutter axle center finding and axial positioning mechanism and a sliding block through a connecting groove. The right end of the fixture base is adjustably connected with a pressing stirring mechanism. The sliding block is positioned between the cutter axle center finding and axial positioning mechanism and the pressing stirring mechanism. A locking mechanism is arranged on each of the cutter axle center finding and axial positioning mechanism and the sliding block. A second V-shaped positioning plate is fixedly connected to the front end face of the sliding block, and a first V-shaped positioning plate is fixedly connected to the right end face of the fixture base. The cutter is positioned and centered by the axle center finding and axial positioning mechanism and the V-shaped positioning plates to facilitate the accurate clamping of a product, parameters such as circular runout of the cutter are conveniently measured by the pressing stirring mechanism, the whole tool is unlimited to the parameter measurement of the cutter in a certain specification, and the pressing stirring mechanism is adjusted upwards and downwards to ensure practicability for cutters in different specifications.

The invention relates to the mechanical field, in particular to a shaft distance calibrating method. The method comprises the following steps that 1, a drilling shaft or a threading shaft of a drilling-threading machine is selected as a coordinate reference shaft, and machining files of three holes are written, wherein the machine coordinate of the first hole is (0,0), any X and Y machine coordinate of the second hole accords with the corresponding coordinate of the first hole, and the machine coordinate of the third hole is an any value; 2, the first hole and the second hole are machined on a circuit board through a reference shaft of the drilling-threading machine, and the third hole in machined on the circuit board through the other shaft; 3, the actual coordinate value of the third hole in the circuit board is detected through quadratic element detection equipment; and 4, according to the difference value between the machine coordinate of the third hole and the actual coordinate, the shaft distance between the two shafts of the drilling-threading machine is calculated. The shaft distance calibrating method is easy and practical, the machining precision problem caused by deformation caused by thermal expansion of workpieces and a mechanical structure is solved, and equipment machining performance is improved.

The invention relates to an invented feeding buffer device mechanism. The quadratic element mechanical arm feeding-in-place buffer mechanism comprises a transmission shaft (1), the transmission shaft (1) is connected with an eccentric shaft mechanism through a gear set (2), an eccentric shaft (4) of the eccentric shaft mechanism is connected with a clamping mechanism, the clamping mechanism comprises a base and clamps arranged on two sides of the base, a moving seat connected with the eccentric shaft (4) is arranged on one side of the base, and a fixed seat is arranged on the other side of the base. A stop block (7) is arranged at the front end of the moving seat, a limit block (8) corresponding to the stop block (7) is arranged at the front end of the fixed seat, and a clamped material travel distance is prearranged between the stop block (7) and the limit block (8). Through gear transmission and the arrangement of the eccentric mechanism, the moving seat and the fixed seat, a mechanical arm can achieve high-efficiency and high-precision feeding.
