A kind of turning fixture
The utility model relates to a kind of anchor clamps, is specifically related to a kind of turning fixture.
For the processing of the thin part of wall, existing turning fixture adopts the endoporus location, uses the pressing plate end face to compress, and the back is fastening with nut.This installation way adopts part axial to compress the clamping deformation that has reduced part, and requiring the operator to possess has higher operative skill.But for the thin part of the high wall of required precision; This installation way still can make part deformation, and the extremely difficult control of deflection, also can produce machining deformation; Processing back part form and position tolerance and dimensional tolerance are overproof; Product quality is difficult to controlled, can not meet design requirement, and also can influence manufacturing schedule simultaneously.
Summary of the invention
The purpose of the utility model is exactly the shortcoming that will overcome above-mentioned technology, provides a kind of simple in structure, easy to manufacture, and convenient mounting and clamping, deflection are controlled, the turning fixture that crudy is good, precision is high.
The turning fixture of the utility model comprises body, positioning pressuring plate, clamping nut, screw rod, and positioning screw cap is characterized in that: have additional stressed pressing plate on the described positioning pressuring plate, stressed pressing plate front end is that elastic component, rear end are that rigidity part and splicing are one.
The turning fixture of the utility model is simple in structure, easy to manufacture, through setting up the handing-over pressing plate, has reduced the part deformation that causes because of clamping, and can effectively control the variable quantity of clamping, and the part ovality is controlled in 0.015; Parts fixation is convenient and swift, has improved product quality and production efficiency.

Among the figure 1, body, 2, positioning pressuring plate, 3, stressed pressing plate, 4, clamping nut, 5, screw rod, 6, positioning screw cap, 7, elastic component, 8, the rigidity part, 9, part to be processed.
The specific embodiment
The turning fixture of the utility model comprises body 1, positioning pressuring plate 2, clamping nut 4, screw rod 5; Positioning screw cap 6; Have additional stressed pressing plate 3 on its described positioning pressuring plate 2; Stressed pressing plate 3 front ends are that elastic component 7, rear end are that 8 splicing of rigidity part constitute an integral body, and elastic component 7 is processed by elastoplast and steel plate respectively with rigidity part 8.
During use; Positioning screw cap 6 is fixed on screw rod 5 on the body 1, and part 9 to be processed places on the body 1 through screw rod 5, successively positioning pressuring plate 2, stressed pressing plate 3 is placed on the part to be processed; Tighten clamping nut 4 on the screw rod 5 at last, part 9 clampings to be processed are fixed on the body 1.On its dislocation Lathe bench, can accomplish part processing.
