Description
Technical Field
The utility model relates to the technical field of deep hole detection, in particular to a positioning mechanism for a slender material.
Background
In the production activity, the problem of deep hole detection of materials is often faced. As shown in fig. 1, a slender material 9 is a pin jack unit, which is used for manufacturing an electrical connector, and a deep hole 91 for inserting a conductive terminal or a cable is coaxially arranged at one end of the pin jack unit.
In the elongated material 9 shown in fig. 1, the deep hole 91 is used for the insertion of a conductive terminal or a cable, so that a probe-type deep hole detection needs to be performed on the deep hole 91 to prevent the inside of the deep hole from being blocked. Since the slender material 9 itself belongs to the slender piece, when deep hole detection is performed, the self pose must be accurately maintained to strictly match the detection probe coaxially, otherwise the detection probe and the slender material 9 themselves are easily damaged.
Clearly, there is a need for a reliable positioning mechanism for elongated materials to solve the above problems.

the clamping unit is also provided with a guide pillar which penetrates through the fixed module in the front-back direction, the guide pillar is in sliding fit with the fixed module in the axial direction, the front end of the guide pillar is fixedly connected with the movable module, the rear end of the guide pillar is fixedly connected with a stop block, a spring elastically compressed between the stop block and the fixed module is sleeved on the guide pillar, so that the rear end face of the clamping piece is closed with the front end face of the resisting part, and the first positioning groove and the second positioning groove just clamp and position the slender material in the inner die;
the release unit is provided with a baffle positioned behind the stop block and a first cylinder for driving the baffle to push the stop block along the axial direction of the guide pillar; when the baffle plate pushes the stop block, the rear end face of the clamping piece is separated from the front end face of the resisting part to form clearance fit;
