Detailed Description
The following description will be given to a specific embodiment of the movable contact assembly coaxiality adjusting tool in the present invention with reference to the accompanying drawings.
As shown in fig. 2 and 3, an embodiment of a tool for adjusting coaxiality of a moving contact assembly according to the present invention is as follows: an operator can intuitively judge whether the moving contact assembly meets the coaxiality tolerance requirement by using the moving contact assembly coaxiality adjusting tool 20, can adjust the position of a part on the moving contact assembly under the condition of no disassembly so as to enable the part to meet the coaxiality requirement, and can solidify the joint 16 under the supporting action of the moving contact assembly coaxiality adjusting tool to ensure the coaxiality of a final product. Moving contact assembly axiality timing frock 20 includes frock base 21, frock base 21 is the plate body of rectangle, be provided with supporting seat and positioning seat on frock base 21, because moving contact 11's axial in moving contact assembly 10, radial dimension will correspond the axial than joint 16, radial dimension is big, and weight is heavier, so the supporting seat mainly used supports the moving contact in the moving contact assembly, joint 16 is connected with moving contact 11 with an overhanging form through insulating pull rod 14, joint 16 is very little and here do not consider along vertical direction's offset under the action of gravity, the axis of joint 16 is parallel or very nearly parallel with insulating pull rod 14 and moving contact 11's axis, do not set up the structure that is used for support joint 16 in the timing frock this moment again.
The supporting seat in the moving contact assembly coaxiality adjustment tool 20 comprises two supporting tables 22 arranged at intervals along the moving contact assembly axial direction, the two supporting tables 22 respectively correspond to two end portions of the moving contact 11, the upper end face of each supporting table 22 is a V-shaped groove matched with the outer peripheral face of the moving contact 11, the groove wall of each V-shaped groove is arranged in a V-shaped mode, the moving contact 11 can be automatically centered under the action of gravity when placed in the V-shaped groove, and the V-shaped groove can also provide guiding for the moving contact 11 along the self axial displacement. Because the moving contact 11 can move on the adjustment frock, can not set up fixed clamping structure between moving contact 11 and brace table 22, consequently use the V-arrangement face to also can satisfy the removal cooperation of brace table 22 with moving contact 11 under the prerequisite that can satisfy the support moving contact. A support table through hole 221 through which the positioning pin passes is formed in the support table 22, and a positioning hole corresponding to the through hole in the support table 22 is correspondingly formed in the tooling base 21, so that when the movable contact is assembled with the coaxiality adjusting tooling 20, the relative position relationship between the support table 22 and the tooling base 21 is ensured by a positioning structure formed by the positioning hole and the positioning pin.
The positioning seat in the moving contact assembly coaxiality adjustment tool 20 comprises a positioning support 23 with a U-shaped structure, two overhanging arms corresponding to two sides of the U-shaped structure are arranged in the positioning support 23, and one overhanging arm of the positioning support 23 is attached and fixed to the tool base 21, so that an opening of the positioning support 23 is arranged towards the horizontal direction. The two overhanging arms of the positioning bracket 23 are correspondingly provided with positioning screws 24 as upper and lower positioning parts, the moving directions of the two positioning screws 24 are both arranged along the radial direction of the joint 16, one positioning screw is arranged above the joint 16 and the other positioning screw is arranged below the joint 16, the axes of the positioning screws and the axes of the positioning grooves are intersected and can move towards or away from each other, and the joint 16 can automatically center on the insulating pull rod 14 under the action of only gravity. The space between the two positioning screws 24 forms a joint clamping space for the joint 16 to be clamped into, and the joint clamping space is used for limiting the joint 16 in the vertical direction relative to the movable contact 11 within a set coaxiality requirement range. For example, the requirement of the coaxial tolerance of the movable contact 11 and the joint 16 is x, so when the operator adjusts the relative positions of the two positioning screws 24, the operator may increase x on the diameter of the joint 16 to set the distance between the positioning screws 24 for clamping the joint 16.
