Description

Motor casing both ends of the surface and seam double-pole frame numerically controlled lathe

Technical field:

The utility model relates to a kind of numerically controlled lathe, especially processes the double-pole frame numerically controlled lathe of motor casing both ends of the surface and seam.

Background technology:

The conventional machining process of electric machine casing is with end seam location, processing other end seam; Perhaps with the inner chamber location, motor casing two ends seam is processed in tune at twice.Not only working (machining) efficiency is low, and because the error that processing mode is improper and resetting causes makes the motor casing inner chamber very big to the runout error of two ends seam axis, causes defectives such as motor noise is big, heating.

Summary of the invention:

The purpose of this utility model provides a kind of motor casing both ends of the surface and seam double-pole frame numerically controlled lathe, to clamping of motor casing, finishes the turning of both ends of the surface and seam, can improve precision and production efficiency.

The purpose of this utility model realizes as follows: the end fixed main shaft case above the base, motor is set on the base, motor power links to each other with the main shaft of device on main spindle box, other end rear side immovable support base above the base, but the slide plate of two move left and right is housed on the tool rest bracket, knife rest moving up and down is housed on the slide plate, and the knife rest lower end is end face, endoporus, chamfer cutter fixedly; Front-end of spindle connects the expander anchor clamps, and an end that is in the expander anchor clamps on the base is provided with positioner, to motor casing axial location to be processed.

The expander anchor clamps have a holder, holder is used for joining with main shaft, the holder endoporus has an extension bar, be with mobile pushing sleeve on the anterior cylindrical of holder, the fixedly connected pin of extension bar front end, the slide opening that connecting pin passes on the holder is connected with mobile pushing sleeve, mobile pushing sleeve periphery is with expander, the contact-making surface of mobile pushing sleeve and expander is the corresponding conical surface, the expander inner side end leans against on the boss of holder, and the holder end is provided with locking nut, and locking nut leans on the end face of the expander outside, extension bar is connected with the main shaft draw-in bar, and pull bar is connected with disk spring with the ad hoc cylinder of forging a knife.Extension bar drives mobile pushing sleeve and moves, and makes expander harmomegathus, and motor casing is enclosed within on the expander clamped or unclamp.

It is based on centre numerically controlled lathe, has changed position, the quantity of knife rest.Anchor clamps tensioner motor casing inner chamber with novel utilizes the double-pole frame to process motor casing two ends seam, end face and chamfering simultaneously.Anchor clamps link to each other with machine tool chief axis, and main shaft is driven by synchronous by variable-frequency motor, thus the realization cutting movement, the double-pole frame is by four servomotors, and difference is vertical, laterally mobile, thereby realizes feed motion.

The beneficial effects of the utility model are: a clamping is finished the processing of two ends seam, end face, chamfering, has effectively controlled the motor casing inner chamber to the beating of two ends seam axis, and has significantly improved production efficiency.

Description of drawings:

Fig. 1 is the structural representation of the utility model motor casing both ends of the surface and seam double-pole frame numerically controlled lathe.

Fig. 2 is the structural representation of expander anchor clamps.

The specific embodiment:

With reference to Fig. 1, end fixed main shaft case 10 above the base 2, motor 1 is set on the base 2, motor 1 power links to each other with the main shaft of device on main spindle box 10, motor 1 is a variable-frequency motor, the other end rear side immovable support base above the base 2, but the slide plate of two move left and right is housed on the tool rest bracket, knife rest 8 moving up and down is housed on the slide plate, and knife rest 8 lower ends are end face, endoporus, chamfer cutter fixedly; Front-end of spindle connects expander anchor clamps 6, and an end that is in expander anchor clamps 6 on the base 2 is provided with positioner 7.Also be provided with chip cleaner 3, cooling device 4, lubricating arrangement 5 on the base 2, base 2 rear portions are provided with machine shield 11, fix automatically controlled plate 9 on the machine shield 11.

During use, motor casing is enclosed within on the expander anchor clamps 6, the nearly main shaft end face of electric machine casing leans against on the axial direction positioning device 7, finish axial location, after 6 pairs of motor casings of expander anchor clamps clamp, drive main shaft by synchronous band, thereby make expander anchor clamps 6 rotations that are connected on the main shaft by motor 1, the rotation of drive workpiece provides the cutting active force.Double-pole frame 8 is respectively by 4 driven by servomotor, and is can be free horizontal, vertical shift is moving, realizes the tool feeding motion, and lubricating arrangement 5 provides an amount of lubricating oil to tool guide and leading screw.Chip cleaner 3 transports the iron filings that the processing back produces automatically, and cooling device 4 is isolated plants that cooling fluid is provided for processing aluminum motor casing, and machine shield 11 not only can effectively be protected lathe, and makes mechanical part and electrical appliance part obtain perfect adaptation.

With reference to Fig. 2, expander anchor clamps 6 have a holder 12, holder 12 is used for joining with main shaft, holder 12 endoporus have an extension bar 15, be with mobile pushing sleeve 16 on the holder 12 anterior cylindricals, the fixedly connected pin 14 of extension bar 15 front ends, the slide opening that connecting pin 14 passes on the holder 12 is connected with mobile pushing sleeve 16, mobile pushing sleeve 16 peripheries are with expander 13, and mobile pushing sleeve 16 is the corresponding conical surface with the contact-making surface of expander 13, and expander 13 inner side ends lean against on the boss of holder 12, holder 12 ends are provided with locking nut 17, locking nut 17 leans on expander 13 outside end faces, and extension bar 15 is connected with the main shaft draw-in bar, and pull bar is connected with disk spring with the ad hoc cylinder of forging a knife.To the clamping of workpiece with unclamp, cylinder and disk spring cooperate realization by forging a knife, the cylinder of forging a knife promotes the pull bar in the main shaft and compresses disk spring, extension bar 15 moves in holder 12, release mobile pushing sleeve 16 by connecting pin 14, expander 13 shrinks, and expander 13 external diameters diminish, and workpiece is released; Otherwise the cylinder of forging a knife is return, the disk spring pushing drawing rod, and extension bar 15 retracts mobile pushing sleeve 16 by connecting pin 14, and expander 13 expands, and expander 13 external diameters increase, and workpiece is clamped.
