Description

Technical Field

[0001] The invention belongs to the field of turning, and in particular relates to a parallel dual-spindle dual-station intelligent turning center which is convenient for loading materials. Background Art

[0002] A parallel twin-spindle turning machine is an advanced CNC lathe. Its core feature is its two parallel spindles, enabling simultaneous machining of two identical or different materials. When turning shafts, existing twin-spindle turning machines utilize a robot to grip the workpiece, insert it into the center locking hole of the chuck, and secure it. The turning head then moves to the desired position for turning, and the robot removes the finished workpiece.

[0003] This type of turning equipment presents the following challenges: During turning, the robot is responsible for not only gripping and transporting the shaft material but also aligning it. Due to the limited space in the turning station, it can only load shorter shafts or discs, which is a significant limitation. Furthermore, some turning equipment equipped with dual spindles and dual stations requires dual robots, which increases the equipment's operating and maintenance costs and burdens due to the high precision requirements. Using a single robot, however, does not improve efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 -Attached Figure 7 This application is described in further detail.

[0028] Please refer to Figure 1 、 Figure 2 and Figure 3 A parallel dual-spindle, dual-station intelligent turning center designed for easy loading includes a turning cabinet 1 with an internal turning chamber 2. A window connecting to the turning chamber 2 is provided on the front of the turning cabinet 1, and the window is equipped with a sealed door. A main controller is fixedly mounted on the front side of the turning cabinet 1, to the right of the window. A ram's horn-shaped fixing seat 3 is fixed to the lower side of the turning chamber 2. Two symmetrical clamping members 4 are mounted on the fixing seat 3. A turning mechanism 5 and a loading mechanism 6 are located within the turning chamber 2, located on the front and rear sides of the fixing seat 3, respectively.

[0029] See Figure 2 and Figure 4The turning mechanism 5 includes two fixed seats 3 51 fixedly arranged on the lower side of the turning chamber 2 and symmetrically arranged on the left and right sides. A screw 1 52 is rotatably arranged on the upper side of the fixed seat 3 51 through an ear seat 1. The screw 1 52 is threadedly connected to a slide rail 1 53 that is slidably connected to the fixed seat 3 51. A screw 2 54 is rotatably arranged on the slide rail 1 53 through an ear seat 2. The screw 2 54 is threadedly connected to a slide rail 2 55 that is slidably connected to the slide rail 1 53. A tool head mounting seat is fixedly arranged on the upper side of the slide rail 2 55, and a turning tool head 56 is equipped on the mounting seat. A motor 3 is fixedly arranged on either ear seat 1 or ear seat 2. The two motors 3 are respectively fixedly connected to the corresponding ends of the screw 1 52 and the screw 2 54. The two motors 3 drive the screw 1 52 and the screw 2 54 to rotate, thereby driving the slide rail 1 53 and the slide rail 2 55 to move along a predetermined route, thereby controlling the turning tool head 56 to move to a specified position for turning processing.

[0030] See Figure 3 、 Figure 5 and Figure 6 The clamping member 4 includes a rotating shaft 41 that is rotatably mounted on the front side of the fixed seat 3 and extends through its rear side. The rotating shaft 41 is a hollow structure with both ends open. The front end of the rotating shaft 41 is fixedly connected to a coaxial pneumatic chuck 42, which has a locking hole in the middle. The rotating shaft 41 and the fixed seat 3 are jointly connected to a drive assembly 7. The drive assembly 7 includes a motor 71 fixed to the rear side of the fixed seat 3 via a mounting plate. The output shaft of the motor 71 and the rotating shaft 41 are jointly connected to a gear set 72. The gear set 72 consists of two intermeshing gears: one is fixedly connected to the output shaft of the motor 71, and the other is fixedly mounted on the surface of the corresponding rotating shaft 41. The motor 71 cooperates with the gear set 72 to rotate the rotating shaft 41, thereby driving the rotation of the pneumatic chuck 42.

[0031] See Figure 3 、 Figure 5 、 Figure 6 and Figure 7 The loading mechanism 6 includes a fixed seat 2 61 fixedly arranged on the lower side of the turning chamber 2, and a rotating component 62 is rotatably arranged on the upper side of the fixed seat 2 61. Two symmetrical rotating rings 63 are provided on the rotating component 62, and four groups of filling components 64 are evenly distributed along the circumference of the rotating ring 63. Two symmetrical cylinders 1 65 are fixedly arranged in the turning chamber 2 through brackets. The cylinder 1 65 is located inside the corresponding rotating ring 63. The telescopic end of the cylinder 1 65 is fixedly connected to a push plate 66, and the front side of the push plate 66 is provided with a pressure detector.

[0032] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6Two symmetrical feed ports 15 are located on the back of the turning cabinet 1. Each feed port 15 is used to receive an external conveyor for shaft-type workpieces. A guide platform 16 is fixedly mounted within the turning chamber 2, directly above the two rotating rings 63. Two symmetrical guide tubes 17 are fixedly mounted on the guide platform 16. These tubes 17 are shaped like a trumpet, wide at the top and narrow at the bottom. The end of the external conveyor is located above the upper end of the guide tubes 17.

[0033] During specific operation, the two external conveying devices respectively deliver the shaft workpieces one by one into the two guide tubes 17 on the guide table 16. The shaft workpieces are vertically received by the loading assembly 64 through the guide tube 17, and then the loading assembly 64 containing the shaft workpieces is rotated 90° to align with the pneumatic chuck 42 through the rotating assembly 62. The shaft workpiece is pushed toward the pneumatic chuck 42 through the cylinder 1 65 and the push plate 66 and locked after reaching the specified position.

[0034] See Figure 3 、 Figure 5 and Figure 6 A groove is formed on the upper side of the second fixing seat 61. The rotating assembly 62 includes a second rotating shaft 621 that is rotatably mounted on the upper side of the second fixing seat 61 and extends through the groove. The left and right ends of the second rotating shaft 621 are fixedly connected to the corresponding rotating ring 63 via multiple connecting rods evenly arranged around the circumference. A second driving assembly 622 is connected between the second rotating shaft 621 and the second fixing seat 61. The second driving assembly 622 includes a second motor 6221 fixedly mounted on the right side of the second fixing seat 61. A second gear set 6222 is disposed between the output shaft of the second motor 6221 and the second rotating shaft 621. The second gear set 6222 includes two meshing second gears: one second gear is fixedly connected to the output shaft of the second motor 6221, and the other second gear is fixedly mounted on the surface of the second rotating shaft 621. The second motor 6221 cooperates with the gear set 6222 to drive the second rotating shaft 621 to rotate, causing the loading assemblies 64 on the two rotating rings 63 to switch positions.

[0035] See Figure 5 and Figure 6 The outer wall of the rotating ring 63 is provided with four through-holes evenly distributed along its circumference. The filling assembly 64 includes a filling tube 641 fixedly mounted on the outer side of the rotating ring 63 and located at the outer end of the through-holes. Two ring plates 642 are installed inside the filling tube 641 at the end closest to the rotating ring 63. Springs 643 are fixedly connected to the opposing sides of the two ring plates 642. The ring plate 642 closest to the rotating ring 63 is fixedly mounted within the filling tube 641, while the ring plate 642 farther from the rotating ring 63 is slidably mounted within the filling tube 641. The diameter of the push plate 66 is smaller than the circular hole on the surface of the ring plate 642, allowing the push plate 66 to pass through the ring plate 642.

[0036] During specific operation, when loading, the turning tool head 56 is moved to the front side position of the pneumatic chuck 42 and keeps a certain distance from the end face of the pneumatic chuck 42 (the position of the turning tool head 56 at this time is the position of the rear end head of the shaft workpiece after it is locked on the pneumatic chuck 42). When the shaft workpiece falls vertically, it falls into the loading barrel 641. One or more shaft workpieces can be loaded at a time. According to the size of the shaft workpiece, the lower end of the shaft workpiece collides with the sliding ring plate 642. The impact force generated is buffered by the spring 643. Then the rotating ring 63 rotates under the drive of the rotating assembly 62, and the originally vertical workpiece is rotated to a horizontal state to align with the pneumatic chuck 42. At this time, the cylinder 1 65 extends, driving the push plate 66 to enter the loading barrel 641 from the through-hole port of the rotating ring 63. The push plate 66 continues to move through the ring plate 642 to push the shaft workpiece in the loading barrel 641 toward the end of the rotating shaft 1 41. The shaft workpiece then enters the interior of the rotating shaft 41 and passes through the rotating shaft 41, so that the front end of the shaft workpiece passes from the locking hole at the center of the pneumatic chuck 42 from the back to the front, and the front end of the shaft workpiece finally contacts the turning tool head 56 lying across the front side of the front chuck. The pressure of the pressure detector exceeds the threshold, thereby controlling the cylinder 65 to stop extending. At this time, the other end of the shaft workpiece stays in the locking hole of the pneumatic chuck 42, and the locking position of the shaft workpiece is determined. The shaft workpiece is then locked by the pneumatic chuck 42, and the turning tool head 56 then turns the fixed shaft workpiece according to the established route. After turning is completed, the pneumatic chuck 42 contacts and locks, and the push plate 66 continues to push the front shaft workpiece forward, pushing the completed workpiece out of the pneumatic chuck 42. If only one workpiece is loaded into the loading cylinder 641 at a time, the push plate 66 returns to the initial position and waits for the next work. If there are multiple workpieces, after the front workpiece is discharged, the second workpiece is locked in the same way as the first workpiece, and the operation is repeated.

[0037] See Figure 6 and Figure 7 To reduce friction when the shaft-like workpiece slides within the loading cylinder 641, four circumferentially distributed ball groups 644 are provided on the inner wall of the loading cylinder 641. Each ball group 644 is composed of multiple balls rotatably mounted on the inner wall of the loading cylinder 641. The multiple balls within each ball group 644 are evenly distributed along the length of the loading cylinder 641. The balls roll against the surface of the shaft-like workpiece.

[0038] See Figure 3 and Figure 4, a collecting seat 8 is fixedly connected between the opposite sides of the fixed seat three 51, and three collecting grooves 9 are opened on the upper side of the collecting seat 8, and the collecting grooves 9 are arranged in a slope shape with the front lower and the back higher. The upper side of the collecting seat 8 is respectively provided with two left and right symmetrical material guide plates 10 through the connecting shaft. The front ends of the two connecting shafts are fixedly provided with gear three 11, and the upper side of the left gear three 11 and the lower side of the right gear three 11 are provided with tooth plates 12, which mesh with the corresponding gear three 11. The ends of the two tooth plates 12 close to each other are fixedly connected by a connecting plate, and the surface sliding sleeve of the connecting plate is provided with a guide sleeve 13 fixedly connected to the front side of the collecting seat 8. The front side of the collecting seat 8 is fixedly connected to a cylinder two 14, and the output shaft of the cylinder two 14 is fixedly connected to the right tooth plate 12.

[0039] During operation, the expansion and contraction of cylinder 2 (14) drives the two toothed plates (12), thereby driving the two corresponding gears (3) (11) to rotate and drive their respective guide plates (10). During turning, the two guide plates (10) rotate to a position perpendicular to the collection seat (8), allowing the chips generated by turning to fall into the collection slots (9) on the left and right sides of the collection seat (8). After turning, the two guide plates (10) rotate a certain angle, so that they are tilted and lie across the top of their corresponding collection slots (9). At this time, the pneumatic chuck (42) is unlocked, and after the turning head (56) gives way, cylinder 1 (65) drives the push plate (66) to continue moving, pushing the finished shaft workpiece from the pneumatic chuck (42) onto the guide plates (10), and then sliding into the central collection slot (9).

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
