Description
Technical Field
The utility model belongs to the field of positioning fixtures, and particularly relates to a linear cutting positioning fixture for an elastic ring of a combustion engine.
Background
The existing thin-wall large-size elastic ring for the gas turbine is matched with the end face of the ball bearing, the special structure of the boss with 6 nitriding parts on the end face of the elastic ring ensures that the bearing is stressed uniformly and stably, the original manufacturing process of the boss structure is finished by milling processing center equipment, in the production and manufacture process, the cutter is often severely worn due to the fact that the nitriding surface hardness of the end face of the boss structure is high, the processing surface quality of a workpiece is low, meanwhile, the workpiece deforms due to cutting force, and the flatness after processing is poor due to the fact that the wall thickness of the workpiece is thin.
Disclosure of Invention
The utility model aims to provide a linear cutting positioning clamp for an elastic ring of a combustion engine, which changes the milling processing of the original process into linear cutting processing of a new process, and eliminates the problems of the existing manufacturing process.
A linear cutting and positioning clamp for an elastic ring of a combustion engine comprises a supporting bottom plate, a reinforcing rib, a fixing bolt A, an elastic spring, an elastic nut, a sleeve, a quick-inserting positioning device, a supporting vertical plate and an indexing turntable; the sleeve is fixed on one side of the supporting vertical plate through a fixing bolt A; the supporting rod of the indexing turntable passes through the supporting vertical plate and the sleeve from the other side of the supporting vertical plate, and is sleeved with an elastic spring and fixed through an elastic nut; the quick inserting positioning device is arranged on the supporting vertical plate and used for positioning the indexing turntable; the indexing turntable secures the workpiece to an end face thereof by a platen.
Further, the quick-insertion positioning device comprises a quick-insertion positioning pin, a quick-insertion positioning spring and a quick-insertion positioning sleeve; the quick-insertion positioning sleeve is fixed on the supporting vertical plate through a fixing bolt B; the quick-inserting positioning pin penetrates through the quick-inserting positioning sleeve and the supporting vertical plate to be used for positioning the indexing turntable, and the quick-inserting positioning spring is sleeved on the quick-inserting positioning pin.
The utility model has the beneficial effects that:
the utility model solves the problems that the cutter is seriously worn and the quality of the cutting surface is poor due to the fact that the nitriding surface is high and the wall thickness of the workpiece is thin when the boss special structure of the elastic ring is manufactured at present, and simultaneously solves the problem that the deformation is caused by the cutting force, and ensures the size and form tolerance of the workpiece. The application of a new process is realized, the one-time qualification rate of the product quality is improved, the production cost of workpieces is reduced, and great economic benefit is generated.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1, the elastic ring wire cutting positioning fixture of the gas turbine comprises a supporting bottom plate 1, a reinforcing rib 2, a fixing bolt A3, a tension spring 4, a tension nut 5, a sleeve 6, a quick-inserting positioning device, a supporting vertical plate 10 and an indexing turntable 11; the sleeve 6 is fixed on one side of the supporting vertical plate 10 through a fixing bolt A3; the supporting rod of the indexing turntable 11 passes through the supporting vertical plate 10 and the sleeve 6 from the other side of the supporting vertical plate 10, and is sleeved with an elastic spring 4 and fixed by an elastic nut 5; the quick inserting positioning device is arranged on the supporting vertical plate 10 and is used for positioning the indexing turntable 11; the indexing turntable 11 fixes the workpiece on the end face of the workpiece through the pressing plate, so that the workpiece can rotate along with the turntable indexing mechanism, when the workpiece rotates by 60 degrees along with the turntable indexing mechanism, the upper boss and the lower boss are positioned at the linear cutting molybdenum wire processing position, and when the turntable indexing mechanism rotates for 3 times, namely the workpiece rotates for 3 times along with the turntable indexing mechanism, the whole processing of the boss structure of the workpiece can be completed after the workpiece rotates by 180 degrees.
The quick-inserting positioning device comprises a quick-inserting positioning pin 7, a quick-inserting positioning spring 8 and a quick-inserting positioning sleeve 9; the quick-insertion positioning sleeve 9 is fixed on the supporting vertical plate 10 through a fixing bolt B12; the quick-inserting locating pin 7 passes through the quick-inserting locating sleeve 9 and the supporting vertical plate 10 to be used for locating the indexing turntable 11, the quick-inserting locating pin 7 is sleeved with the quick-inserting locating spring 8, and the device can complete the function of limiting the workpiece and the indexing turntable mechanism to be in a machining position after rotating every 60 degrees.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
