All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-11, an automatic high-efficiency turning and milling device for manufacturing an end cap of a cast aluminum alloy comprises a machine body 11, wherein the machine body 11 is provided with a first spindle box 12, a second spindle box 13 and at least one group of tool rests 14, the first spindle box 12 and the second spindle box 13 are horizontally and slidably mounted on the machine body 11 and are respectively arranged on two sides of the tool rests 14, and three-jaw chucks 15 arranged oppositely are mounted on the first spindle box 12 and the second spindle box 13; the three-jaw chuck 15 is provided with a clamping part 16 and adjusting columns 17 for adjusting the radial movement of the clamping part 16 along the three-jaw chuck 15, and the adjusting columns 17 are arranged at intervals along the circumferential direction of the three-jaw chuck 15.
As a further aspect of the present invention, the bottom portions of the first headstock 12 and the second headstock 13 are each provided with a coupling mechanism for coupling the two adjustment columns 17 to rotate synchronously when the two three-jaw chucks 15 approach each other and overlap in the horizontal direction.
The invention can automatically turn over and clamp the workpiece to be processed without manual operation. As shown in fig. 1, a workpiece to be machined is placed on the three-jaw chuck 15 on the first headstock 12 to be clamped and positioned, and the tool post 14 is driven to perform turn-milling machining on the workpiece. When one surface of a workpiece is machined and needs to be turned over, the first spindle box 12 is driven to slide on the lathe bed 11 and move towards the direction close to the second spindle box 13, the first spindle box 12 and the second spindle box 13 are driven to synchronously rotate by driving the adjusting columns 17 on the first spindle box 12 and the second spindle box 13 until the three-jaw chucks 15 of the first spindle box and the second spindle box are overlapped in the horizontal direction, the clamping part 16 of the three-jaw chuck 15 on the first spindle box 12 is gradually loosened to the maximum state from the clamping state, and simultaneously the clamping part 16 of the three-jaw chuck 15 on the second spindle box 13 is gradually clamped from the maximum state until the clamping state is reached. Because the two three-jaw chucks 15 have the same specification and are concentrically arranged, the radial direction of the workpiece does not deviate after being loosened and clamped; in addition, because the clamping part 16 of the invention moves slowly, the workpiece is not subjected to force in the horizontal direction in the processes of loosening and clamping, the horizontal axial direction of the workpiece is not deviated, the clamping state of the workpiece is not changed, and the tool setting is not required again. After the workpiece is clamped again, the first spindle box 12 is far away from the second spindle box 13, and the tool rest 14 performs turning and milling processing on the workpiece clamped and fixed on the second spindle box 13 to finish the turn-over processing.
As a further aspect of the present invention, the connecting mechanism includes an adjusting ring 21 disposed below the three-jaw chuck 15, and the adjusting ring 21 is vertically slidably mounted on the first spindle box 12 and the second spindle box 13; the second spindle box 13 is provided with a connecting seat 22; the two ends of the connecting seat 22 are rotatably provided with rotating shafts 23, and the rotating shaft 23 close to one end of the second spindle box 13 is fixedly connected with the adjusting ring 21 on the second spindle box 13; an inner gear ring 24 is fixedly arranged on the rotating shaft 23 close to one end of the first spindle box 12, and an outer gear ring 25 is fixedly arranged at the bottom of the adjusting ring 21 on the first spindle box 12; the two rotating shafts 23 are both fixedly provided with synchronous wheels 27, and the two synchronous wheels 27 are in transmission connection through a synchronous belt 26; the ring gear 24 is a half ring gear.
As a further scheme of the present invention, the connecting seat 22 is slidably mounted on the bed 11 and connected with the jacking unit; the jacking unit is used for driving the adjusting ring 21 to be connected with the adjusting column 17 when the two three-jaw chucks 15 are close to each other and overlapped in the horizontal direction.
The rotation of the adjusting column 17 is driven and adjusted by an adjusting ring 21 arranged below the adjusting column, and the specific adjusting mode is that the adjusting ring 21 is jacked up, so that the adjusting column 17 can be inserted into the adjusting ring 21, and then the adjusting column 17 is driven to rotate by rotating the adjusting ring 21, and the three-jaw chuck 15 is controlled to clamp and loosen. The present invention requires the synchronous driving connection of the two adjusting rings 21 when the three-jaw chucks 15 are close to each other and overlapped in the horizontal direction. As shown in fig. 10 and 11, in the present invention, when the adjusting ring 21 on the first headstock 12 moves toward the second headstock 13 along with the first headstock 12, when the two three-jaw chucks 15 are overlapped in the horizontal direction, the adjusting ring 21 on the first headstock 12 just moves to the inner gear ring 24 on the connecting seat 22, and at this time, the outer gear ring 25 at the bottom of the adjusting ring 21 on the first headstock 12 is engaged with the inner gear ring 24. The arrangement of "inner ring gear 24 is a half ring gear" is such that outer ring gear 25 can translate into engagement with inner ring gear 24. The jack-up unit drives the whole connecting base 22 to move up and jack up, so that the two adjusting columns 17 are inserted into the respective adjusting rings 21, and then drives any rotating shaft 23 to rotate for adjustment, wherein the rotating shaft 23 on the side close to the second spindle box 13 is driven to rotate for adjustment in the embodiment. Since the two rotating shafts 23 are synchronously connected by the timing belt 26 and the timing wheel 27, they synchronously rotate to complete the turnover clamping of the workpiece.
As a further aspect of the present invention, the connecting mechanism further includes a sliding block 31 fixedly disposed at the bottom of the first headstock 12 and the second headstock 13, and the sliding block 31 is provided with an interleaving unit for driving the three-jaw chucks 15 to rotate when the two three-jaw chucks 15 are overlapped with each other in the horizontal direction, so that the clamping portions 16 of the two three-jaw chucks 15 are interleaved with each other.
As a further aspect of the present invention, the interleaving unit includes two guide posts 32 respectively rotatably mounted on the two sliding blocks 31, and the two guide posts 32 are respectively connected to the spindles on the first spindle box 12 and the second spindle box 13 in a synchronous manner; the end part of one side of the guide column 32 close to the tool rest 14 is provided with a fan-shaped guide block 33, the fan-shaped guide blocks 33 are arranged at intervals along the circumferential direction of the guide column 32, and wedge surfaces 34 are arranged on two circumferential sides of the fan-shaped guide block 33.
In the invention, when the two three-jaw chucks 15 are close to and overlapped, attention needs to be paid to staggering the clamping parts 16 on the two three-jaw chucks 15 so as to avoid equipment damage caused by collision between the two parts. However, after the first head stock 12 stops rotating after machining is completed, the presence of the rotational inertia makes it difficult to accurately position the clamp portion 16 on the first head stock 12 after the rotation has stopped, and therefore, it is difficult to interleave the clamp portions 16 on both sides. As shown in fig. 9, according to the present invention, the first head stock 12 and the second head stock 13 are provided with the guide columns 32, and the guide columns 32 are synchronously coupled to the respective spindles. When the three-jaw chucks 15 approach each other, the sector-shaped guide blocks 33 on the guide posts 32 contact first. Note that, as shown in fig. 5 and 8, the angle at which the fan-shaped guide blocks 33 on the two guide posts 32 are provided at intervals in the circumferential direction of the guide posts 32 is the same as the angle at which the respective clamp portions 16 are provided at intervals in the circumferential direction of the three-jaw chuck 15, and when the fan-shaped guide blocks 33 on both sides are staggered with each other, the clamp portions 16 on both sides are also staggered with each other. After the two sector guide blocks 33 are contacted, the two sector guide blocks are guided by the wedge surfaces 34 to enable the two sector guide blocks to be mutually staggered, then the guide columns 32 are used for synchronously driving the respective main shafts to rotate, the three-jaw chuck 15 is driven to rotate, the two clamping portions 16 are also mutually staggered, and the phenomenon that when the two three-jaw chucks 15 are close to and overlapped with each other, the clamping portions 16 on the two three-jaw chucks 15 collide to damage equipment is avoided.
As a further aspect of the present invention, the jack-up unit includes a drive rod 41 fixedly provided on the first headstock 12 and a jack-up rod 42 provided on the second headstock 13, respectively; the driving rod 41 jacks the rod 42 and is arranged on the guide post 32; the drive rod 41 is coaxially arranged with the guide post 32 on the first headstock 12, the jacking rods 42 are arranged at intervals along the circumferential direction of the guide post 32 on the second headstock 13, and the length direction of the jacking rods 42 is consistent with the radial direction of the guide post 32 on the second headstock 13; one end of the jacking rod 42 is provided with a slope surface contacting with the driving rod 41, and the other end is provided with a jacking block 43 for jacking the connecting seat 22.
According to the invention, the connecting seat 22 needs to be driven to jack up when the two three-jaw chucks 15 are overlapped, so that the adjusting column 17 can be inserted into the adjusting ring 21, and the adjusting ring 21 is convenient to adjust. As shown in fig. 8, the driving rod 41 is provided on the guide post 32 of the first headstock 12, when the two sides approach each other, the driving rod 41 is inserted into the guide post 32 of the second headstock 13, the jacking rod 42 is driven by the inclined surface to move towards the periphery of the guide post 32, and the jacking block 43 on the jacking rod 42 jacks up the connecting seat 22 located above the jacking rod, so that the adjusting post 17 can be inserted into the adjusting ring 21. After the turning over is finished, the first spindle box 12 is far away from the second spindle box 13, the driving rod 41 is far away along with the first spindle box 12, the jacking rod 42 resets under the action of self gravity, the connecting seat 22 moves downwards to reset, and the adjusting ring 21 is separated from the adjusting column 17.

When the three-jaw chuck 15 of the first headstock 12 is unclamped, the three-jaw chuck 15 of the second headstock 13 is not yet clamped to the workpiece, and the workpiece is moved by gravity. Although the workpiece is not subjected to axial force at this time, and the workpiece is subsequently repositioned at the original position along with the continuous turning, the workpiece may incline due to gravity at this time, so that the workpiece clamped again has an error with the original fixed position, and therefore, the expanding mechanism is arranged, the three-jaw chuck 15 on one side is loosened, and the three-jaw chuck 15 on the other side is not clamped yet, the workpiece is expanded and supported, so that the workpiece is prevented from inclining. As shown in fig. 7 and 3, when the three-jaw chucks 15 on both sides are overlapped, the fixing ring 51 on the second headstock 13 already extends into the workpiece, the jacking block 43 jacks up the connecting seat 22, and the expanding rack 57 fixedly connected to the connecting seat 22 moves up along with the connecting seat 22, so that the rotating rod 54 is driven to rotate by the expanding gear 56. As shown in fig. 7, the rotating rod 54 rotates, and the protruding portion 55 thereof pushes up the expanding ring 52, so that the expanding ring 52 is expanded to the outside of the fixed ring 51, and pushes against the workpiece, thereby preventing the workpiece from tilting.
