Description
Technical Field
The utility model relates to a device of lathe processing dysmorphism casing belongs to machining technical field.
Background
The existing speed reducer shell structure is more and more complex, an ordinary machine tool cannot directly machine eccentric holes and end faces on a special-shaped shell, most of the existing speed reducer shell structures need a multi-axis machining center to machine the eccentric holes and the end faces, the cost is too high, and the period is longer if the existing speed reducer shell structures are machined by an external aid.
Disclosure of Invention
The utility model aims to provide a: the device for machining the special-shaped shell by the lathe can utilize a numerical control lathe to machine the special-shaped shell under the condition that equipment is not newly added, so that investment is reduced, and cost is saved.
The utility model discloses a device of lathe processing dysmorphism casing, including location axle, bottom plate, cushion and locating plate, seted up first through-hole and second through-hole respectively in the central authorities of bottom plate and locating plate, the equipartition has three cushion between bottom plate and locating plate, the cushion both ends pass through screw and bottom plate and locating plate fixed connection, at the inboard fixedly connected with location axle of locating plate, worn the bolt on the locating plate, there is the clamp plate at the end connection of bolt.
Furthermore, one end of the positioning shaft is provided with a screw rod which is connected with the positioning shaft into a whole, and the screw rod penetrates out of the positioning plate and then is in threaded connection with the nut.
Furthermore, a limiting groove is formed in the cushion block, and the bottom of the pressing plate extends into the limiting groove and is in sliding fit with the limiting groove.
Since the technical scheme is used, the utility model has the advantages of: the utility model discloses having changed the clamping mode of work piece, under the circumstances of not newly-increased equipment, can utilizing numerical control lathe just can process special-shaped casing through the device, like this alright adopt numerical control lathe to replace machining center to process special-shaped casing, realize the precision finishing of eccentric orfice and terminal surface on the special-shaped casing, broken away from the dependence of casing processing to machining center, reduce and drop into, practice thrift the cost.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail with reference to the accompanying drawings and examples.
The embodiment of the utility model provides a: referring to fig. 1, a device for lathe machining of a special-shaped shell comprises a positioning shaft 1, a bottom plate 2, cushion blocks 3 and a positioning plate 6, wherein a first through hole 7 and a second through hole 8 are respectively formed in the centers of the bottom plate 2 and the positioning plate 6, the three cushion blocks 3 are uniformly distributed between the bottom plate 2 and the positioning plate 6, two ends of each cushion block 3 are fixedly connected with the bottom plate 2 and the positioning plate 6 through screws 4, the positioning shaft 1 is fixedly connected to the inner side of the positioning plate 6, a bolt 10 penetrates through the positioning plate 6, and a pressing plate 9 is connected to the end portion of the bolt 10. One end of the positioning shaft 1 is provided with a screw rod which is connected with the positioning shaft 1 into a whole, and the screw rod penetrates out of the positioning plate 6 and then is in threaded connection with the nut 5. The cushion block 3 is provided with a limiting groove 11, and the bottom of the pressing plate 9 extends into the limiting groove 11 and is in sliding fit with the limiting groove 11.
Referring to fig. 2, when in use, firstly, the special-shaped shell 12 is placed between the bottom plate 2 and the positioning plate 6, the round hole on the special-shaped shell 12 is positioned through the positioning shaft 1 on the positioning plate 6, then the cushion block 3 between the bottom plate 2 and the positioning plate 6 is fixed through the screw 4, and the bolt 10 is simultaneously screwed, so that the pressure plate 9 on the end part of the bolt 10 presses the special-shaped shell 12, thus the center of the special-shaped shell 12 can be changed through the positioning of the positioning shaft 1, the eccentric hole 13 to be processed and the center of the lathe spindle are on the same straight line, and the purpose that the lathe can process the eccentric hole 13 and the end face of the special-shaped shell. After the special-shaped shell 12 is positioned and clamped, the tool is clamped to a lathe head, the positioning plate 6 is clamped by a chuck, the excircle runout of the positioning plate 6 is corrected to be less than 0.005mm by means of the end face, and then a boring cutter on a numerical control lathe penetrates through a first through hole 7 on the positioning plate 6 to process an eccentric hole 13 and the end face of the shell. After one end of the eccentric hole 13 is machined, the tool is taken down from the chuck, the chuck is used for clamping the bottom plate 2, the end face of the positioning plate 6 is positioned, the outer circle and the end face run-out of the positioning plate 6 are corrected to be less than 0.005mm, and then a boring cutter on a numerical control lathe penetrates through the second through hole 8 on the bottom plate 2 to machine the eccentric hole 13 and the end face at the other end of the shell.
