Abstract
The utility model discloses a three-jaw automatic centering pump cylinder fixture. The three-jaw automatic centering pump cylinder fixture is characterized in that the three-jaw automatic centering pump cylinder fixture comprises a positioning pressing position (2), chuck jaws (3) and a lathe carrier (4), wherein the positioning pressing position (2) is arranged in the central position of the lather carrier (4), the carrier jaws (3) are evenly distributed on the lathe carrier (4) along the positioning pressing position (2), each carrier jaw (3) is machined to be in an inner cone shape, and certain taper exists between each chuck jaw (3) and the position, clamped by the carrier jaw (3), of the protruding edge of the outer circle of a pump cylinder (1). The three-jaw automatic centering pump cylinder fixture solves the technical problems of improving installation fastness of the pump cylinder and improving machining efficiency of the pump cylinder.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of three-jaw automatic centring pump barrel fixture.
Background technology
The current processing for pump barrel, be generally the centering for workpiece pump barrel at seam of lathe dog end face car, three independently pressing plates are installed on chuck end face, for three clamping points of clamping pump barrel, during clamping, must compress respectively three pressing plates, to complete the clamping to pump barrel.Weak point of the prior art is that pressing plate only pushes down the cylindrical chimb of pump barrel one end, and whole microscler pump barrel overhangs at chuck end face, so armoring effect is bad, process likely there will be loosening, causes scrapping of processing pump barrel.
Utility model content
The utility model provides a kind of three-jaw automatic centring pump barrel fixture, and its object is to improve the installation firmness of pump barrel and the working (machining) efficiency of pump barrel.
In order to realize above object, the design that the utility model adopts is: a kind of three-jaw automatic centring pump barrel fixture, it is characterized in that, and it comprises location step-by-step (2), jaw (3), lathe dog (4); Described location step-by-step (2) is installed on the center of lathe dog (4); It is upper that described jaw (3) is uniformly distributed in lathe dog (4) along location step-by-step (2), and jaw (3) is processed into the inner conical that has certain taper with pump barrel (1) cylindrical chimb clamping place.
The beneficial effects of the utility model: (1) convenient mounting and clamping, operating efficiency is high.(2) clamping is reliable, can not become flexible, and is conducive to improve the quality of products.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
At the numerical reference described in Figure of description, be expressed as: 1, pump barrel; 2, location step-by-step; 3, jaw; 4, lathe dog.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
Referring to Fig. 1, a kind of three-jaw automatic centring pump barrel fixture, it comprises location step-by-step (2), jaw (3), lathe dog (4); Described location step-by-step (2) is installed on the center of lathe dog (4); It is upper that described jaw (3) is uniformly distributed in lathe dog (4) along location step-by-step (2), and jaw (3) is processed into the inner conical that has certain taper with pump barrel (1) cylindrical chimb clamping place.
Operation principle of the present utility model: when turn lathe dog clamping lever, three jaws are simultaneously by pump barrel chimb Automatic-clamping, and inner conical surface is firmly by chimb locking, once completes and clamps action.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby which key element the process, method, article or the equipment that make to comprise a series of key elements not only comprise, but also comprise other key elements of clearly not listing, or be also included as the intrinsic key element of this process, method, article or equipment.The in the situation that of more restrictions not, the key element being limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment that comprises key element and also have other identical element.
Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred embodiment of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
