Description
Technical Field
The utility model relates to a wedge-shaped workpiece thread turning special fixture for a high-speed rail.
Background
At present, all parts of the high-speed rail locomotive in China are basically realized in localization. Many of its components have proprietary or unique structural designs, involving the need for protection of technical secrets. Therefore, a plurality of parts of the machine tool are required to be processed by a plurality of different factories to finish the processing of different parts and structures of a workpiece in actual processing.
The wedge-shaped workpiece for the high-speed rail is a part used on a high-speed rail locomotive, and belongs to a nonstandard part with a unique structure. When the special positioning fixture is used for machining, special positioning fixtures are needed for ensuring machining precision and working efficiency and improving workload.
Disclosure of utility model
The technical purpose of the utility model is to provide the wedge-shaped workpiece thread turning special fixture for the high-speed rail, which can greatly improve the processing efficiency and ensure the processing precision and other technological requirements.
In order to achieve the technical purpose of the utility model, the technical scheme adopted is as follows:
The utility model provides a wedge work piece threading special fixture for high-speed railway, includes the anchor clamps pedestal of demountable installation on the processing machine tool workbench, the anchor clamps pedestal is cylindrical platy, is fixed with in the preceding lower part of anchor clamps pedestal and is horizontally backup pad with anchor clamps pedestal front vertical, be equipped with simultaneously with anchor clamps pedestal and backup pad vertically in the limiting plate that is located the centre position in the backup pad, be equipped with the locating screw hole to the limiting plate in the place ahead, correspond the locating screw hole and be equipped with the location clamp plate, be equipped with strip location slotted hole at the location clamp plate central authorities to set up positioning bolt, accessible positioning bolt passes the location slotted hole on the location clamp plate with the location clamp plate will wait that the wedge work piece for high-speed railway also is fixed in the location anchor clamps pedestal through the locating screw hole location during the use.
The operation process of the positioning clamp in application comprises the steps of firstly installing the clamp through a base body on a working table of a processing machine tool to fix, almost installing the clamp base on various processing machines, then pasting the bottom surface of a wedge body to be processed on a supporting plate, enabling two support arm-shaped structures to penetrate through a limiting plate, and then propping one side of a positioning pressing plate against the limiting plate and fixing the wedge body on the clamp base through a positioning bolt.
The beneficial effects of the utility model are as follows:
Wedge workpieces for high-speed rails require machining of a plurality of structures on different machine tools due to the specificity of their external structures. The utility model can finish the work of the protruding cylinder thread turning at the front end of the wedge body, and can also fix the wedge body on other machine tools through the positioning clamp to finish the special wedge slope milling processing of the two support arm-shaped structures, and the like. The structural arrangement of the clamp does not prevent various machining such as threading of two support arm-shaped structures and the cylindrical protruding part at the front end. The clamping and positioning requirements of a wedge-shaped workpiece on a non-passing machine tool can be met through the clamp. The design of the fixture not only has the universality on different machine tools, but also can meet the requirement that various machine tools do not interfere with the machining of a plurality of special parts and structures of the workpiece during the machining of the workpiece.
Drawings
FIG. 1 is a schematic view of the positioning fixture and corresponding wedge-shaped workpiece of the present utility model when not assembled in a split configuration.
FIG. 2 is a schematic view of the assembly of the positioning fixture and the corresponding wedge workpiece according to the present utility model.
In the figure, a fixture seat body 1, a support plate 2, a limit plate 3, a positioning and compacting plate 4, a strip-shaped positioning slot hole 6 and a wedge-shaped body 6.
Detailed Description
Referring to fig. 1 and 2, an embodiment of a wedge-shaped workpiece threading special fixture for a high-speed rail comprises a fixture base body 1 detachably mounted on a working table of a processing machine tool, wherein the fixture base body 1 is in a cylindrical plate shape. A support plate 2 which is vertical and horizontal to the front surface of the clamp seat body 1 is fixed at the lower part of the front surface of the clamp seat body 1. The supporting plate 2 is provided with a limiting plate 3 which is vertical to the clamp seat body 1 and the supporting plate 2 and is positioned at the center. The front of the limiting plate 3 is provided with a positioning threaded hole right to the limiting plate 3. A positioning compacting plate 4 is arranged corresponding to the positioning threaded hole. The center of the positioning and pressing plate 4 is provided with a strip-shaped positioning slot 5 and is provided with a positioning bolt, and when the positioning and pressing plate is used, a workpiece to be machined, namely a wedge-shaped body 6 workpiece for a high-speed rail, can be positioned and fixed on the positioning fixture seat body 1 through the positioning screw hole 4 by the positioning pressing plate 4 through the positioning slot 5 on the positioning and pressing plate 4 when in use.
