The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Embodiment: as Fig. 1 and shown in Figure 3, the present invention relates to a kind of two-sided car owner's axle lengthening head structure that is applied in the numerically controlled lathe of two-sided (end) processing, it comprises main spindle box 3 and lengthening head 1, two-sided lathe for machining is when the different part of processing axial length, process the bigger part of axial length by the mode that main spindle box 3 apolegamys is connected lengthening head 1, and can match the lengthening head 1 of different axial length sizes according to the size of part axial length to be processed.After main spindle box 3 has been proofreaied and correct precision, change the precision that different lengthening heads 1 can not influence main spindle box 3, and increase the clamping mode for the treatment of processing parts behind the lengthening head 1 and can not change.
Be provided with the extension shaft 6 that the rotary main shaft 17 with main spindle box 3 is complementary in the lengthening head 1, lengthening head 1 two ends connect the outer rim of main spindle box 3 and clamp mechanism respectively, the center of ground releasable connection rotary main shaft 17 and clamp mechanism is mated at extension shaft 6 two ends respectively, promptly be equipped with respectively that coupling connects the casing 4 of main spindle box 3 and clamp mechanism and periphery at lengthening head 1 two ends and offer the flange holder structure in a plurality of fixedly connected holes, the end that extension shaft 6 is connected with rotary main shaft 17 also is provided with and rotary main shaft 17 match that be connected and the peripheral flange holder structure that offers a plurality of fixedly connected holes.Between casing 4 and clamp mechanism (as shown in Figure 3), the hole of fixedlying connected of the flange holder structure of (as shown in Figure 2) interfixes by screw between casing 4 and lengthening head 1, between lengthening head 1 and clamp mechanism and between rotary main shaft 17 and extension shaft 6.After laying down screw, dismounting can be separated the flange holder structure between the above-mentioned parts.Mix the high extension shaft of precision 6 in addition, an end of extension shaft 6 is plugged in the rotary main shaft 17, and the other end is supported in the lengthening head 5 by bearing 7, under the supporting of bearing 7, can enlarge the processing length scope of machined into axial workpiece.As the variation example of present embodiment, also can adopt the mode of clamping to connect described casing 4 and clamp mechanism.
Main spindle box 3 comprises casing 4, rotary main shaft 17, synchronizing wheel 11, servomotor 2, retaining mechanism and clamp mechanism.Clamp mechanism is arranged on casing 4 two ends, can load and unload between itself and the casing 4, promptly adopts bolt to connect or clamping, and can radially clamp or radially unclamp part to be processed.Retaining mechanism and clamp mechanism form the two ends that an integral installation fits over main spindle box 3.
Rotary main shaft 17 and extension shaft 6 inside are hollow, can by and place the part to be processed that feeder 5 is transported to main spindle box 3.
Synchronizing wheel 11 is sheathed on the rotary main shaft 17 and the servomotor 2 that is in transmission connection.
Servomotor 2 drives rotary main shaft 17 by synchronizing wheel 11 and rotates, and the main axle servo clamping device comes the part different to be processed of clamping stress deformation by the moment of regulating servomotor 2.
Clamp mechanism be arranged on casing 4 two ends and can and casing 4 between load and unload, it comprises left clamp mechanism and the right clamp mechanism that can radially clamp or radially unclamp part to be processed simultaneously, this left side clamp mechanism and right clamp mechanism are arranged on rotary main shaft 17 two ends, its structure is corresponding to, and be the two ends that are arranged on rotary main shaft 17 symmetrically, so when servomotor 2 drove rotary main shaft 17 rotations and the rotation of retaining mechanism locking clamp mechanism, left clamp mechanism and right clamp mechanism radially clamped simultaneously or radially unclamp.Left side clamp mechanism comprises left binding nut 14, left spring chuck 13 and left positioning sleeve 12, right clamp mechanism correspondence comprise right binding nut 20, right collet 21 and right positioning sleeve 22.An end and its outside outer wall that the left spring chuck 13 of left side clamp mechanism is arranged at rotary main shaft 17 are round table-like that the bottom surface radius increases laterally.Left side positioning sleeve 12 is sheathed on the left spring chuck 13 and its outside inwall is the round table-like hollow-out parts that is complementary with left spring chuck 13 outside outer walls.The outer wall of left side positioning sleeve 12 is provided with screw thread, left side binding nut 14 is set on the left positioning sleeve 12 and inwall is provided with and left positioning sleeve 12 screw thread that is complementary, the outside inwall of left side binding nut 14 is formed with an inwardly protruded left clamping ring, left side clamping ring is close to the outer end of left spring chuck 13, makes left binding nut 14 be the opening profile of tooth that left spring chuck 13 is locked in inside outwardly generally.When utilizing relative to rotary main shaft 17, rotates to the inside when moving by left binding nut 14, the left clamping ring of left side binding nut 14 is inwardly pushed left spring chuck 13, because left spring chuck 13 has tapering with the contact-making surface of left positioning sleeve 12, make left spring chuck 13 inwardly push part to be processed simultaneously, thereby finish the work that clamps part to be processed; Accordingly, when left binding nut 14 directions were moved, left spring chuck 13 outwards unclamped part to be processed.
The right binding nut 20 of right clamp mechanism, right collet 21 and right positioning sleeve 22 are arranged at the other end of rotary main shaft 17, its structure is identical with left clamp mechanism, and be symmetrically arranged, the direction of rotation of screw thread that is the right binding nut 20 of the left binding nut 14 of left clamp mechanism and right clamp mechanism is opposite, make when rotary main shaft 17 rotations, the left binding nut 14 of left side clamp mechanism and the right binding nut 20 of right clamp mechanism can move simultaneously to the inside or simultaneously laterally, thereby make left spring chuck 13 and right collet 21 can radially clamp or unclamp part to be processed simultaneously.In the present embodiment, because lengthening head 1 is installed in the main spindle box right side, retaining mechanism can the locking clamp mechanism rotate in the extension shaft 6 so right collet 21 is plugged on, and it comprises left retaining mechanism and the right retaining mechanism that is arranged on main axle servo clamping device both sides respectively with left clamp mechanism and right clamp mechanism accordingly.Left side retaining mechanism comprises left locking cylinder 16 and left latch segment 15, and left locking cylinder 16 is fixed on the main axle servo clamping device can push-and-pull left side latch segment 15, rotation that can the corresponding left binding nut 14 of locking when left latch segment 15 is released by left locking cylinder 16.Accordingly, right retaining mechanism comprises right locking cylinder 18 and right latch segment 19, right locking cylinder 18 is fixed on the main axle servo clamping device can the right latch segment 19 of push-and-pull, rotation that can the corresponding right binding nut 20 of locking when right latch segment 19 is released by right locking cylinder 18.Left side locking cylinder 16 and right locking cylinder 18 can be cylinders, also can be oil cylinders.
The course of work of main spindle box 3 of the present invention and lengthening head 1 assembling is as described below: as at first the clamp mechanism and the retaining mechanism integral body of main spindle box one side to be pulled down from the casing of main spindle box 3, then lengthening head 1 is installed on the casing of main spindle box, again clamp mechanism and the retaining mechanism of pulling down reinstalled on the lengthening head 1, promptly finished the installation process of lengthening head 1 with main spindle box 3.
