Abstract

The utility model relates to a device for processing changing ellipsoid work, which belongs to a turning machine accessory. In the utility model, a clapper box and a turning tool are arranged on a base plate through a rotating shaft and a spring; a sliding sleeve is arranged on the base plate through a shaft bearing and a bearing seat; a shaft of a changing ellipsoid is arranged in the sliding sleeve, and a groove with the pitch on the bottom side is arranged on the side of a generating line. The roller on the clapper box presses on the cam of an emulating ellipsoid; an emulating shape contact head is arranged on the emulating ellipsoid. The base plat is fixed on a lathe slide plate. The utility model has the advantages of convenient use and low cost, which is especially suitable for manufacturing the workpieces with changing ellipsoid shapes, such as a piston, a mould, etc.

Description

The oval processing unit (plant) of a kind of change

The utility model is a kind of turning machine annex, the oval processing unit (plant) of particularly a kind of change.

Before the utility model is made, become oval processing and adopt digital control technology, the cost costliness, adopt the device of mechanical system, as Chinese patent " 92222556.7 high-accuracy elliptical profile forming mechanism " and " 95110340 ellipse processing machine " is to adopt the pocket-wheel architecture, can not process to become disciform workpiece.

The purpose of this utility model provides the oval processing unit (plant) of a kind of change, have easy to use, cost is low, the characteristics being convenient to promote, can be used for machining piston, mould etc. to have the workpiece that becomes elliptical profile.

The technical solution of the utility model is by rotating shaft 7 and spring 21 rocking knife carrier 6 and lathe tool 10 to be installed on base plate 18, by bearing and bearing block sliding sleeve 4 is installed on the base plate 18, cylindrical imitative ellipse cam 1, be installed on the sliding sleeve 4 by rotating shaft 20, becoming elliptical shaft 3 is installed in the sliding sleeve 4, and on side bus, have the groove of bottom surface band gradient, the one end links by universal coupling 14 and power gear group 11, power gear group 11 and pillar 15 are housed on the support 13, the roller 5 that is installed on the rocking knife carrier 6 is pressed on the imitative ellipse cam 1, imitative type contact 19 is housed on the imitative ellipse cam 1, and is pressed in the groove that becomes elliptical shaft 3 by the pulling force of spring 2.During work, workpiece 9 is contained in 12 of lathe spindle 8 and tailstocks by mandrel, mandrel one end and power gear group 11 link, base plate 18 is fixed on the lathe slide plate, lathe tool 10 cutting workpieces 9 when machine tool chief axis rotates, because the effect of spring 21, roller 5 is pressed on the imitative ellipse cam 1, promote rocking knife carrier 6 and lathe tool 10, process oval workpiece 9.Because the groove bottom that becomes on elliptical shaft 3 buses has a gradient, imitative type contact 19 can and become 3 angles of elliptical shaft along with the imitative ellipse cam 1 of the mobile change of base plate 18, makes the workpiece that processes have the change elliptical shape.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a kind of embodiment front view of the present utility model;

Fig. 2 is the side view of Fig. 1.

Fig. 1 is installed with rocking knife carrier 6 and lathe tool 10 by rotating shaft 7 and spring 21 on base plate 18, by bearing and bearing block sliding sleeve 4 is installed on the base plate 18, cylindrical imitative ellipse cam 1, be installed on the sliding sleeve 4 by rotating shaft 20, becoming elliptical shaft 3 is installed in the sliding sleeve 4, and on side bus, have the groove of bottom surface band gradient, the one end links by universal coupling 14 and power gear group 11, power gear group 11 and pillar 15 are housed on the support 13, the roller 5 that is installed on the rocking knife carrier 6 is pressed on the imitative ellipse cam 1, imitative type contact 19 is housed on the imitative ellipse cam 1, and is pressed in the groove that becomes elliptical shaft 3 by the pulling force of spring 2.During work, workpiece 9 is contained in 12 of lathe spindle 8 and tailstocks by mandrel, mandrel one end and power gear group 11 link, base plate 18 is fixed on the lathe slide plate, lathe tool 10 cutting workpieces 9 when machine tool chief axis rotates, because the effect of spring 21, roller 5 is pressed on the imitative ellipse cam 1, promote rocking knife carrier 6 and lathe tool 10, process oval workpiece 9.Because the groove bottom that becomes on elliptical shaft 3 buses has a gradient, imitative type contact 19 can and become 3 angles of elliptical shaft along with the imitative ellipse cam 1 of the mobile change of base plate 18, makes the workpiece that processes have the change elliptical shape; On support 13, also can taper gauge 16 be housed, roller 17 is housed on base plate 18, be pressed on the taper gauge 16 by pillar 15.In process, taper gauge 16 can promote base plate 18 and drive lathe tool 10, and car goes out the oval workpiece of change of various band taperings or curved surface, to satisfy the different Mould Machining that require.

The various patterns that the utility model particularly suitable is used in the machining piston machining tool have processing side Just, the low characteristics of cost.
