Abstract
The utility model relates to a non-through-hole part machining fixture which comprises a mandrel, a coupling and a nut. The mandrel is divided into a front end and a tail end. The tail end of the mandrel is a cone-shaped section with the diameter sequentially enlarged. The front end of the cone-shaped section of the mandrel is provided with a thread section; the nut is connected with the thread section of the mandrel in a threaded fit mode; and the coupling is sleeved on the cone-shaped section of the mandrel. The non-through-hole part machining fixture is simple in structure and easy to operate, can not give rise to deformation of a thin-wall part, solves the problem of part basic errors caused in the machining process and improves surface machining accuracy.
Description
Technical field
The utility model belongs to the machine tooling field, is specifically related to a kind of non through hole part processing anchor clamps.
Background technology
At present, traditional lathe grinding non through hole part cylindrical all is first processing parts endoporus, by screw thread fixed central spindle mode, the other end adopts the top mode that holds out against, but because there is the gap all the time in the cooperation in mandrel and hole, the part that requirement on machining accuracy is higher, particularly beat when having relatively high expectations, adopt the method processing parts, there is influence in the benchmark of part at the circle in the internal hole of cylindrical, serious meeting is scrapped part fully, waste of manpower and material resources.
Summary of the invention
In view of this, the utility model provides a kind of non through hole part processing anchor clamps, and is simple in structure, and processing ease has solved the part fiducial error problem that causes in the process, has improved the Surface Machining precision.
The utility model discloses a kind of non through hole part processing anchor clamps, comprise mandrel, ringfeder and nut, described mandrel is divided into front end and tail end, described mandrel tail end is the conical section that diameter increases successively, described mandrel conical section front end is provided with thread segment, described nut is connected with mandrel thread section threaded engagement, and described ringfeder is set in the mandrel conical section.
Further, described ringfeder is an opening sleeve, and its inwall and mandrel conical section tapering are complementary.
Beneficial effect of the present invention is: non through hole part processing anchor clamps of the present utility model, to be inserted in mandrel tail end conical section with the ringfeder that mandrel tail end conical section tapering is complementary, and ringfeder placed in the part perforate, regulate the nut on the mandrel tail end conical section front end thread segment, make nut press the ringfeder front end, the realization ringfeder is radially expanded, reaching zero-clearance with part perforate inwall cooperates, the utility model is simple in structure, processing ease, neither can cause the thin-walled parts distortion, also solve the part fiducial error problem that causes in the process, improve the Surface Machining precision.
Description of drawings
For the purpose, technical scheme and the advantage that make utility model is clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a use schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, a kind of non through hole part processing anchor clamps, comprise mandrel 1, ringfeder 2 and nut 3, described mandrel 1 is divided into front end 1a and tail end 1b, mandrel front end 1a and machining tool main shaft are concentric, described mandrel tail end 1b is the conical section 1c that diameter increases successively, described mandrel conical section 1c front end is provided with thread segment 1d, described nut 3 is connected with mandrel thread section 1d threaded engagement, described ringfeder 2 is set in mandrel conical section 1c, by adjusting nut 3, makes nut 3 press ringfeder 2 front ends, mandrel conical section 1c and ringfeder 2 mutual extrusion are radially expanded ringfeder 2.
In the present embodiment, described ringfeder 2 is an opening sleeve, and its inwall and mandrel conical section 1c tapering are complementary, and are that ringfeder 2 is radially expanded uniformly, cooperates with part 4 perforate inwall zero-clearances.
Use non through hole part processing anchor clamps of the present utility model, to be inserted in mandrel tail end conical section 1c with the ringfeder 2 that mandrel tail end conical section 1c tapering is complementary, and ringfeder 2 placed in part 4 perforates, regulate the nut 3 on the mandrel tail end conical section 1c front end thread segment 1d, nut 3 presses ringfeder 2 front ends, realize that ringfeder 2 is radially expanded, reach zero-clearance with part 4 perforate inwalls and cooperate.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
