Abstract
The utility model relates to a turning fixture, which comprises a fixture body, a positioning column, a retaining ring, an elastic ring, a first pressing plate, a second pressing plate, a first fastening piece and a second fastening piece. The positioning column is arranged in the center of the fixture body. The retaining ring is arranged in the center of the fixture body and is concentric with the positioning column. The elastic ring is arranged between the positioning column and the retaining ring. The first pressing plate and the second pressing plate are spliced to be a pressing plate through the first fastening piece. A round hole is formed in the center of the pressing plate. The pressing plate is fixed on the fixture body through the second fastening piece. The turning fixture provided by the utility model has the advantages that the structure is simple, the clamping is convenient to conduct, the labor intensity of operators is reduced, the positioning accuracy is high, the turning efficiency and the turning quality of workpieces are improved and the turning fixture is suitable for mass production.
Description
Technical field
The utility model relates to a kind of anchor clamps, relates in particular to a kind of anchor clamps for turning support class part, belongs to the Workpiece clamping device technical field of machining.
Background technology
Support class part is widely used in the valve products such as gate valve and stop valve.Support class part as shown in Figure 1 when its two ends are processed in turning, needs bigger diameter end and miner diameter end that higher axiality is arranged, and therefore need use anchor clamps.Turning adds man-hour, and the method that adopts is usually, at first processes its bigger diameter end, then with turning processing upper end, bigger diameter end location.But clamp structure complexity in the past, position error is big, so precision is lower, and the clamping trouble, reduced production efficiency when having increased operator's labour intensity, be not suitable for batch process.
The utility model content
The utility model purpose is that a kind of simple in structure, accurate high turning clamp of convenient mounting and clamping and location is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of turning clamp comprises clamp body, reference column, baffle ring, elastic ring, first pressing plate, second pressing plate, first securing member and second securing member; Described clamp body central authorities are provided with reference column; Described baffle ring is arranged on clamp body central authorities, and is concentric with reference column; Be provided with elastic ring between described reference column and baffle ring; Described first pressing plate and second pressing plate are pressing plate by the first securing member amalgamation; Described pressing plate central authorities have circular hole; Described pressing plate is fixed by second securing member and clamp body.
Preferably, be provided with packing ring between described second securing member and pressing plate.
Preferably, described first securing member is screw bolt and nut.
Preferably, described second securing member is fastening bolt.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Turning clamp of the present utility model, add man-hour, at first the bigger diameter end with workpiece to be processed is enclosed between reference column and the baffle ring, make elastic ring between workpiece and baffle ring to be processed, use first securing member that first pressing plate and second pressing plate are pressing plate in the pars intermedia amalgamation of workpiece to be processed then, then use second securing member that pressing plate and clamp body are fixed, in the process that screws second securing member, elastic ring is compressed, played the effect of self-centering and clamping workpiece to be processed, so just can carry out turning to the miner diameter end of workpiece and process.Turning clamp of the present utility model, simple in structure, convenient mounting and clamping has reduced operator's labour intensity, and the positioning accuracy height, has improved the turning efficient of workpiece and the turning quality of workpiece, is applicable to batch process.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of support class part;
Accompanying drawing 2 is the front view of turning clamp of the present utility model;
Accompanying drawing 3 is the structural representation of turning clamp of the present utility model;

Wherein: 1, clamp body; 2, reference column; 3, baffle ring; 4, elastic ring; 5, first pressing plate; 6, second pressing plate; 7, circular hole; 8, packing ring; 9, bolt; 10, nut; 11, fastening bolt; 12, workpiece.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Be depicted as a kind of turning clamp described in the utility model as accompanying drawing 2,3, comprise clamp body 1, reference column 2, baffle ring 3, elastic ring 4, first pressing plate 5, second pressing plate 6, first securing member and second securing member; Described clamp body 1 central authorities are provided with reference column 2; Described baffle ring 3 is arranged on clamp body 1 central authorities, and is concentric with reference column 2; 3 of described reference column 2 and baffle rings are provided with elastic ring 4; Described first pressing plate 5 and second pressing plate 6 are pressing plate by the first securing member amalgamation; Described pressing plate central authorities have circular hole 7; The radius of described circular hole 7 is less than the radius of the bigger diameter end of workpiece 12, greater than the radius of workpiece 12 pars intermedias; Described pressing plate is fixing by second securing member and clamp body 1; Be provided with packing ring 8 between described second securing member and pressing plate; Described first securing member is bolt 9 and nut 10; Described second securing member is fastening bolt 11.
Be a kind of turning clamp described in the utility model as shown in Figure 4, add man-hour, at first the bigger diameter end with workpiece to be processed 12 is enclosed between reference column 2 and the baffle ring 3, make elastic ring 4 between workpiece to be processed 12 and baffle ring 3, use bolt 9 and nut 10 that first pressing plate 5 and second pressing plate 6 are pressing plate in the pars intermedia amalgamation of workpiece to be processed 12 then, then use fastening bolt 11 fixing pressing plate and clamp body 1, in the process that screws fastening bolt 11, elastic ring 4 is compressed, played the effect of self-centering and clamping workpiece 12 to be processed, so just can carry out turning to the miner diameter end of workpiece 12 and process.
Turning clamp of the present utility model, simple in structure, convenient mounting and clamping has reduced operator's labour intensity, and the positioning accuracy height, has improved the turning efficient of workpiece and the turning quality of workpiece, is applicable to batch process.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
