Description

[0002] Horizontal five-axis linkage turning and milling composite machines can integrate multiple machining processes such as turning, milling, boring, and drilling. With the advantages of one-time clamping and high positioning accuracy, they are widely used in high-end manufacturing fields such as aerospace, precision machinery, and automotive parts. They effectively avoid the error problems caused by multiple clamping and are the core equipment for integrated machining of precision parts. Existing horizontal five-axis linkage turning and milling composite machines are mostly used for precision machining of long round rod workpieces. Long workpieces have poor stability in the middle and are prone to shaking, which can easily affect the machining accuracy. Summary of the Invention

[0003] The purpose of this invention is to solve the problem mentioned in the background art that existing horizontal five-axis linkage turning and milling composite machines are mostly used for precision machining of long round rod workpieces. Long workpieces have poor stability in the middle and are prone to shaking, which easily affects the machining accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A horizontal five-axis linkage turning and milling compound machine includes a machine body with a main spindle mechanism and a secondary spindle mechanism on the machine body; an auxiliary mechanism is disposed between the main spindle mechanism and the secondary spindle mechanism, the auxiliary mechanism includes a support, a lifting plate is disposed on the support, auxiliary plates rotating on the support are disposed on both sides of the lifting plate, and auxiliary wheels are rotatably connected to the top of the auxiliary plates and the lifting plate. When the lifting plate moves up and down, it drives the auxiliary plates on both sides to swing, thereby causing the auxiliary wheels to press against or disengage from the round rod workpiece.

[0005] Preferably, the lifting plate has symmetrical guide surfaces, and the lower end of the auxiliary plate is rotatably connected to a guide wheel.

[0006] Preferably, a symmetrical recovery plate is rotatably connected to the support, the recovery plate has an arc-shaped groove and a recovery groove, a rotating rod one inserted into the arc-shaped groove is fixed on the lifting plate, and a rotating rod two is rotatably connected to the auxiliary plate.

[0007] Preferably, a lifting rod is slidably connected to the lower end of the lifting plate, and a spring is provided at the top of the lifting rod. The two ends of the spring are respectively connected to the lifting rod and the lifting plate. A pressure sensor is fixed on the lifting rod and is located below the lifting plate.

[0008] Preferably, a stabilizing rod is inserted into the center of the spring, and a slot for the stabilizing rod to move is provided on the lifting plate. The lower end of the stabilizing rod is fixedly connected to the lifting rod, and the upper end of the stabilizing rod is inserted into the slot.

[0009] Preferably, the support is provided with a stabilizing and reinforcing component, which includes a follower block fixed to the auxiliary plate and a stabilizing block located below the follower block and moving laterally. The follower block has a first inclined surface, and the stabilizing block has a second inclined surface.

[0010] Preferably, the stabilizing reinforcement component further includes a base plate fixed on the support, the stabilizing block is slidably connected to the base plate, a rack one that drives the stabilizing block is slidably mounted on the base plate, a rack two is fixed on the lifting rod, and the rack one and rack two are driven by a transmission component.

[0011] Preferably, the base plate is fixed with guide rods distributed on both sides of the stabilizing block, and a pull block is slidably connected to the guide rod. The rack is fixedly connected to the pull block, and a spring is sleeved on the guide rod. The two ends of the spring are fixedly connected to the pull block and the stabilizing block, respectively.

[0012] Preferably, a reinforcing rod is fixed to one end of the stabilizing block and passes through the pull block. A spring three is sleeved on the reinforcing rod. The two ends of the spring three are fixedly connected to the reinforcing rod and the pull block, respectively. The spring two and the spring three are located on both sides of the pull block.

[0013] Preferably, the auxiliary mechanism further includes a base, on which a pusher cylinder is fixed. The output end of the pusher cylinder is fixedly connected to the lifting rod. A lead screw is provided on the machine body and connected to the base. One end of the lead screw is connected to a motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By combining the lifting rod, spring 1, stabilizer rod and pressure sensor, when clamping round rods of different diameters, the pusher cylinder drives the lifting rod to continuously rise, and the pressure sensor senses the clamping pressure in real time. When the pressure reaches the preset threshold of the controller, the drive automatically stops, so that the clamping pressure of workpieces of different sizes is always maintained within the standard range and the pressure fluctuation range is extremely small.

[0015] Through the stabilizing and reinforcing components, and relying on the lifting rod's lifting action linkage transmission components, the stabilizing block is driven to move laterally via rack, pinion, and bevel gear sets. This causes the second inclined surface of the stabilizing block to fit tightly against the first inclined surface of the follower block, forming a mechanical locking structure. After the auxiliary wheel clamps the workpiece, the two-way elastically coordinated springs (springs two and three) continuously provide elastic preload, ensuring that the two inclined surfaces remain tightly fitted. This effectively locks the swing angle of the auxiliary plate and the lifting position of the lifting plate. Furthermore, the stroke design of the locking structure can adapt to the clamping and locking requirements of workpieces with different diameters. Attached Figure Description

[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0029] Please see Figures 1-7 A horizontal five-axis linkage milling and turning machine includes a body 1 and an auxiliary mechanism 4. The body 1 has a main spindle mechanism 2 and a secondary spindle mechanism 3. The horizontal movement of the secondary spindle mechanism 3 is existing technology. The auxiliary mechanism 4 is located between the main spindle mechanism 2 and the secondary spindle mechanism 3. The auxiliary mechanism 4 includes a support 41. A lifting plate 42 is provided on the support 41. Limiting blocks are provided on both sides of the lifting plate 42 to maintain the longitudinal movement of the lifting plate 42. The limiting blocks are fixed on the support 41. Auxiliary plates 43 are provided on both sides of the lifting plate 42 and rotate on the support 41. The rotation point is located in the middle part of the auxiliary plate 43. The top of the auxiliary plate 43 and the lifting plate 42 are rotatably connected to the auxiliary plates 43 and the top of the lifting plate 42. When the lifting plate 42 moves up and down, it drives the auxiliary plates 43 on both sides to swing, thereby driving the auxiliary wheels 431 to press against or disengage from the round rod workpiece. The three auxiliary wheels 431 are distributed in the circumferential direction of the round rod workpiece. When they approach each other, they abut against the round rod workpiece, thereby stabilizing the long round rod workpiece.

[0030] The lifting plate 42 has symmetrical guide surfaces 421. A guide wheel 432 is rotatably connected to the lower end of the auxiliary plate 43. A symmetrical recovery plate 44 is rotatably connected to the support 41. The recovery plate 44 has an arc-shaped groove 441 and a recovery groove 442. A rotating rod 422, inserted into the arc-shaped groove 441, is fixed on the lifting plate 42. A rotating rod 433 is rotatably connected to the auxiliary plate 43. When the lifting plate 42 descends, the auxiliary plate 43 is restored by the arc-shaped groove 441 and the recovery groove 442 in the recovery plate 44, in conjunction with the corresponding rotating rods 422 and 433.

[0031] A lifting rod 45 is slidably connected to the lower end of the lifting plate 42. The lifting rod 45 is T-shaped, and a T-shaped groove for the lifting rod 45 is provided on the lifting plate 42. A spring 46 is provided at the top of the lifting rod 45 and is located in the T-shaped groove. When the lifting plate 42 is in the low position, the spring 46 is in a compressed state, and its elastic force lifts the lifting plate 42. The two ends of the spring 46 are connected to the lifting rod 45 and the lifting plate 42 respectively. A pressure sensor 47 is fixed on the lifting rod 45, and a support plate is fixed on the lifting rod 45. The pressure sensor 47 is mounted on the support plate. The pressure sensor 47 is located below the lifting plate 42. A controller is provided on the support 41. The pressure sensor 47 is electrically connected to the controller (not shown in the diagram). The controller has a preset pressure threshold. After the auxiliary wheel 431 contacts the workpiece, the lifting rod 45 continues to rise in order to maintain stable pressure. After the pressure sensor 47 contacts the bottom of the lifting plate 42 and reaches the preset pressure, the lifting rod 45 stops rising. The pressure sensor 47 ensures that the pressure fluctuation range is small when the auxiliary wheel 431 presses workpieces of different sizes, which is beneficial to the stability of the workpiece.

[0032] A stabilizing rod 451 is inserted into the center of the spring 46. A slot 423 for the stabilizing rod 451 to move is provided on the lifting plate 42. The lower end of the stabilizing rod 451 is fixedly connected to the lifting rod 45, and the upper end of the stabilizing rod 451 is inserted into the slot 423. The stabilizing rod 451 is used to stabilize the spring. The slot 423 is opened on the inner top surface of the T-shaped groove and extends into the lifting plate 42.

[0033] A stabilizing reinforcement component 5 is provided on the support 41. The stabilizing reinforcement component 5 includes a follower block 51 fixed on the auxiliary plate 43 and a stabilizing block 52 located below the follower block 51 and moving laterally. The follower block 51 has a first inclined surface 511, and the stabilizing block 52 has a second inclined surface 521. The contact between the first inclined surface 511 and the second inclined surface 521 prevents the lifting plate 42 from falling back and maintains the stability of the workpiece clamped by the auxiliary wheel 431. The longitudinal height of the second inclined surface 521 is higher than the maximum lifting distance of the lifting plate 42, which can accommodate round rod workpieces of different diameters. In the initial state, the first inclined surface 511 and the second inclined surface 521 are not in contact.

[0034] The stabilizing and reinforcing component 5 also includes a base plate 53 fixed on the support 41. The stabilizing block 52 is slidably connected to the base plate 53. A rack 54 that drives the stabilizing block 52 slides on the base plate 53. A rack 55 is fixed on the lifting rod 45. The rack 55 is offset from the recovery plate 44. The rack 54 and rack 55 are driven by a transmission component 56. The transmission component 56 includes a gear 561 that meshes with the rack 54 and a gear 562 that meshes with the rack 55. The gears 561 and 562 are driven by a bevel gear set 563. A gearbox is provided outside the transmission component 56. The gearbox is fixed on the support 41. The gears 561 and 562 are rotatably connected inside the gearbox. The gearbox has a through groove for the movement of the rack 54 and rack 55.

[0035] Guide rods 531, distributed on both sides of the stabilizing block 52, are fixed on the base plate 53. Pull blocks 57 are slidably connected to the guide rods 531. The pull blocks 57 are slidably connected to the two guide rods 531. Rack 1 54 is fixedly connected to the pull blocks 57. Spring 2 58 is sleeved on the guide rods 531. The two ends of spring 2 58 are fixedly connected to the pull blocks 57 and the stabilizing block 52, respectively. When rack 1 54 moves laterally, it drives pull blocks 57 to move together, thereby driving the stabilizing block 52 to move laterally through spring 2 58. Before the auxiliary wheel 431 contacts the workpiece, in order to keep the follower block 51 and the lock relatively stable, the inclination angle of inclined plane 1 511 and inclined plane 2 521 can be set to 45°. Gear 1 561 and gear 2 562 have the same diameter, thereby achieving a one-to-one transmission ratio.

[0036] To further maintain the stability of the movement of the stabilizing block 52, a reinforcing rod 522 passing through the pull block 57 is fixed to the end of the stabilizing block 52. A spring 59 is sleeved on the reinforcing rod 522. The two ends of the spring 59 are fixedly connected to the reinforcing rod 522 and the pull block 57, respectively. Springs 58 and 59 are located on both sides of the pull block 57. The stability of the movement of the stabilizing block 52 is increased by the cooperation of springs 58 and 59.

[0037] The lateral contact distance between inclined plane 1 (511) and inclined plane 2 (521) is less than the upward distance of the lifting rod 45. After the auxiliary wheel 431 contacts the workpiece, the follower block 51 stops moving, and the lifting rod 45 continues to rise. This causes the stabilizing block 52 to continue to move laterally through the transmission assembly 56, the pull block 57, and the second spring 58. After inclined plane 1 (511) and inclined plane 2 (521) contact, the pull block 57 continues to move, causing the second spring 58 to stretch and the third spring 59 to compress, maintaining close contact between inclined plane 1 (511) and inclined plane 2 (521). The auxiliary mechanism 4 also includes a base 48, on which a pusher cylinder 49 is fixed. The output end of the pusher cylinder 49 is fixedly connected to the lifting rod 45. A lead screw 6 is mounted on the machine body 1. This lead screw 6 is independent of the lead screw 6 that drives the secondary shaft mechanism 3 and they do not interfere with each other. The lead screw 6 is connected to the base 48, which is existing technology. One end of the lead screw 6 is connected to a motor 7, which is fixed to the machine body 1. The position of the base 48 can be adjusted by the motor 7 and the lead screw 6, and with the cooperation of the movable secondary shaft mechanism 3, it can adapt to workpieces of different lengths.

[0038] When the equipment is not clamping a workpiece, the auxiliary mechanism 4 is in its initial reset state. The lifting plate 42 and the lifting rod 45 remain in a low position, and the auxiliary plates 43 on both sides are in an open state under the action of the recovery plate 44. The three circumferentially distributed auxiliary wheels 431 are separated from each other and there is no clamping force. The follower block 51 and the stabilizing block 52 of the stabilizing and reinforcing component 5 do not contact each other and are in a separated and unlocked state. At the same time, the pressure sensor 47 has no pressure feedback, the controller is in a standby state, and the overall mechanism has no interference and no pre-tightening force, leaving space for workpiece clamping.

[0039] After the workpiece is clamped, the push cylinder 49 is activated, driving the lifting rod 45 to move upward, which in turn causes the lifting plate 42 to rise vertically along the longitudinal direction of the limiting block of the support 41. The limiting block restricts the lateral displacement of the lifting plate 42 throughout its movement. During the upward movement of the lifting plate 42, its symmetrical guide surfaces 421 on both sides press against the guide wheels 432 at the lower end of the auxiliary plate 43, driving the upper ends of the left and right auxiliary plates 43 to swing inward. At the same time, the recovery plate 44 swings outward.

[0040] Three auxiliary wheels 431, located on the top of the auxiliary plates 43 on both sides and the lifting plate 42, converge synchronously towards the center, gradually pressing against the outer circumference of the round rod workpiece to achieve initial enveloping and clamping of the long round rod workpiece. When the auxiliary wheels 431 contact the workpiece, the limiting effect of the workpiece causes the auxiliary plates 43 and the lifting plate 42 to stop their upward displacement, but the pushing electric cylinder 49 still drives the lifting rod 45 to continue moving upward.

[0041] At this time, the T-slot structure between the lifting rod 45 and the lifting plate 42 slides relative to each other, compressing the spring 46 in the groove. Simultaneously, the pressure sensor 47 fixed on the lifting rod 45 moves upward, contacts the bottom of the lifting plate 42, and generates pressure sensing. The pressure sensor 47 transmits the pressure signal to the controller in real time. When the detected pressure reaches the pressure threshold preset by the controller, the controller controls the push cylinder 49 to stop working and locks the position of the lifting rod 45.

[0042] During the upward movement, the lifting rod 45 moves upward, causing the fixed rack 2 55 to move upward synchronously. Through the transmission of gear 2 562, bevel gear set 563, and gear 1 561, the rack 1 54 meshing with gear 1 561 moves laterally. The rack 1 54 drives the pull block 57 on the base plate 53 to slide laterally along the guide rod 531. The pull block 57 drives the stabilizing block 52 to move laterally synchronously through spring 2 58. Since the lateral contact distance between inclined plane 1 511 and inclined plane 2 521 is less than the upward distance of the lifting rod 45, after the auxiliary wheel 431 contacts the workpiece and the follower block 51 stops moving, the lifting rod 45 continues to rise, causing the stabilizing block 52 to continue to move laterally, so that the two sets of inclined planes are completely in contact and pressed together.

[0043] After the inclined planes are locked in place, the pull block 57 continues to move with the rack 54, stretching the second spring 58 and compressing the third spring 59. Relying on the bidirectional elastic force of the second spring 58 and the third spring 59, the inclined plane 511 and the inclined plane 521 remain tightly fitted. This prevents the follower block 51 from falling back, restricts the descent of the lifting plate 42 and the reverse swing of the auxiliary plate 43, thereby locking the workpiece clamping state and ensuring that the workpiece does not wobble during processing.

[0044] When machining the middle part of the workpiece, the entire mechanism moves to the unmachined or machined circular portion of the workpiece. Specifically, the push cylinder 49 drives the lifting rod 45 to descend, which in turn moves the rack 55 downward. This, in turn, drives the stabilizing block 52 to reset via the transmission assembly 56, disengaging the inclined plane 511 from the inclined plane 521 and releasing the self-locking state. Subsequently, the lifting plate 42 descends with the lifting rod 45, and the auxiliary plates 43 on both sides swing outward under the elastic reset action of the tension springs. The three auxiliary wheels 431 move away from each other and disengage from the workpiece. Then, the mechanism moves laterally via the lead screw 6 and the sliding block, finally re-clamping the workpiece. If the middle part of the workpiece does not need machining, and only the sides are machined, the entire mechanism remains stationary. After machining the workpiece, the entire mechanism returns to its initial standby state, removes the workpiece, and awaits the next clamping operation.
