Abstract
The utility model belongs to machine assembly technique, and relates to improvement of a part locating and clamping structure. The part locating and clamping structure comprises a first locating hole and a second locating hole [4a], wherein the first locating hole is formed in a substrate part [5], and the second locating hole [4a] is formed in a located and clamped part [4]. The part locating and clamping structure is characterized in that the first locating hole is a step hole, the lower portion of a locating sleeve [3] is inserted into an upper-section unthreaded hole [5a] of the first locating hole of the substrate part [5] and in interference fit with the upper-section unthreaded hole [5a], and the upper portion of the locating sleeve [3] is inserted into the second locating hole [4a] of the located and clamped part [4] and in clearance fit with the second locating hole [4a]. According to the part locating clamping structure, a locating part and a clamping part are placed in a coaxial mode, occupied areas are reduced, and locating and clamping requirements of parts having small locating areas are met.
Description
Technical field
The utility model belongs to mechanical assembly technique, relates to the improvement to part locating clip locking structure.
Background technology
In machinery assembling field, often need position and clamp two parts, traditional mode is to locate and clamp in the mode of part two shop bolt holes of brill and minimum two screw holes, and minimum needs drill 4 holes on the part locating surface like this, the processing trouble; Area occupied is big in addition, if the size of part locating surface hour, is difficult to adopt the said structure form.
Summary of the invention
The purpose of this utility model is: a kind of part locating clip locking structure of save area is provided, clamps needs with the location of satisfying the little part of locating surface.
The technical solution of the utility model is: a kind of part locating clip locking structure, comprise first locating hole that is positioned on the matrix part 5 and the second locating hole 4a that is positioned on the clamping part 4 that is positioned, it is characterized in that, first locating hole is a stepped hole, the epimere of this first locating hole is unthreaded hole 5a, hypomere is the screwed hole 5b coaxial with epimere unthreaded hole 5a, the internal diameter of the epimere unthreaded hole 5a of first locating hole equals the internal diameter of the second locating hole 4a, a positioning sleeve 3 is arranged, its bottom is inserted in the epimere unthreaded hole 5a of first locating hole on the matrix part 5 and is kept interference fit, the top of positioning sleeve 3 is inserted in the second locating hole 4a that locatees on the clamping part 4 and is kept matched in clearance, also have packing ring 1 and housing screw 2, packing ring 1 covers to be positioned and clamps the upper port of the second locating hole 4a on the part 4, and housing screw 2 is screwed in the hypomere screwed hole 5b of first locating hole on the matrix part 5 after passing the endoporus of the endoporus of packing ring 1 and positioning sleeve 3.
The utility model has the advantages that: keeper and clamping element coaxial placement, dwindled area occupied, the location of having satisfied the little part of locating surface clamps needs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 1, a kind of part locating clip locking structure, comprise first locating hole that is positioned on the matrix part 5 and the second locating hole 4a that is positioned on the clamping part 4 that is positioned, it is characterized in that, first locating hole is a stepped hole, the epimere of this first locating hole is unthreaded hole 5a, hypomere is the screwed hole 5b coaxial with epimere unthreaded hole 5a, the internal diameter of the epimere unthreaded hole 5a of first locating hole equals the internal diameter of the second locating hole 4a, a positioning sleeve 3 is arranged, its bottom is inserted in the epimere unthreaded hole 5a of first locating hole on the matrix part 5 and is kept interference fit, the top of positioning sleeve 3 is inserted in the second locating hole 4a that locatees on the clamping part 4 and is kept matched in clearance, also have packing ring 1 and housing screw 2, packing ring 1 covers to be positioned and clamps the upper port of the second locating hole 4a on the part 4, and housing screw 2 is screwed in the hypomere screwed hole 5b of first locating hole on the matrix part 5 after passing the endoporus of the endoporus of packing ring 1 and positioning sleeve 3.
The utility model is keeper positioning sleeve 3 and the 2 coaxial placements of clamping element housing screw, thereby saved area occupied, is applicable to the little part of locating surface is positioned clamping.
All have only two locating clip tieholens on the embodiment, the locating surface of certain workpiece and clamped, reduced 50% than the hole number of existing locating clip locking structure.
