A double spindle core shooting machine

Abstract

This invention discloses a dual-spindle Swiss-type machining center, relating to the field of dual-spindle Swiss-type machining centers. It includes a machine body, with a movably mounted blanking box inside. The blanking box has a feed inlet on one side, a sliding groove inside, and rotating rods fixed to both sides. A drive assembly is located at the bottom of the blanking box, and a first bevel gear is fixed to the end of each rotating rod. A material box is fixed to one side of the machine body. When the secondary spindle processes a workpiece, the telescopic rod pushes the blanking box to rotate, causing it to fit tightly against the inner wall of the machine body, preventing debris from splashing into the sliding groove. When unloading is required, the telescopic rod rotates the blanking box to a certain angle, facilitating the workpiece's entry. When the blanking box returns to its original position, it gradually tilts, causing the workpiece inside the sliding groove to fall, preventing blockage.

Description

Technical Field

[0001] This invention relates to the field of twin-spindle sliding head machines, specifically a twin-spindle sliding head machine. Background Technology

[0002] A twin-spindle Swiss-type lathe is a type of mechanical equipment used for processing metals or other materials. It is typically used in scenarios where two spindles need to be used simultaneously for processing, which can significantly improve production efficiency. The twin-spindle Swiss-type lathe achieves the processing through the rotational motion and axial feed motion of the spindles, as well as the rotational motion of the workpiece. During processing, the two spindles can work simultaneously or alternately, and can perform multiple processes such as drilling, reaming, and turning at the same time.

[0003] In existing twin-spindle Swiss-type lathes, after machining a workpiece, the workpiece is placed into a blanking box via a secondary spindle. The blanking box has an open top and is fixed at an angle inside the twin-spindle Swiss-type lathe. When the secondary spindle is machining the workpiece, it generates debris, which splashes and scatters inside the blanking box. When the workpiece slides down, it comes into contact with the metal debris inside the blanking box, causing scratches on the workpiece surface. When the workpiece falls into the rubber-lined blanking box, if the workpiece is light, it will get stuck inside the blanking box, affecting its feeding speed. If the workpiece is heavy, it will fall into the blanking frame at a faster speed and hit the workpiece surface, causing damage. Therefore, it is necessary for personnel to catch the workpiece by hand at the drop-off point, which is quite cumbersome. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a dual-spindle sliding head machine to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dual-spindle sliding head machine, comprising a dual-spindle sliding head machine body, a material feeding box movably installed inside the dual-spindle sliding head machine body, a material inlet on one side of the material feeding box, a sliding groove inside the material feeding box, rotating rods fixed on both sides of the material feeding box, a drive assembly at the bottom of the material feeding box, a first bevel gear fixed at the end of the rotating rod, a material box fixed on one side of the dual-spindle sliding head machine body, a conveying assembly inside the material box, a connecting rod movably installed inside the dual-spindle sliding head machine body, a second bevel gear fixed at the end of the connecting rod, a one-way bearing installed at the end of the connecting rod, a sleeve fitted on the outer wall of the one-way bearing, a transmission rod fixed on one side of the sleeve, and the transmission rod connected to the conveying assembly through a transmission assembly, the drive assembly comprising a telescopic rod and a fixing block, the bottom of the telescopic rod movably connected to the inside of the dual-spindle sliding head machine body, a fixing block fixed at the output end of the telescopic rod, and the fixing block movably connected to the bottom of the material feeding box.

[0006] By adopting the above technical solution, when the secondary shaft processes the workpiece, the telescopic rod pushes the blanking box to flip, so that the blanking box is close to the inner wall of the double spindle sliding head machine body, preventing debris from splashing into the chute. When unloading is required, the telescopic rod drives the blanking box to rotate, so that the blanking box rotates to a certain angle, making it convenient for the workpiece to enter the blanking box. When the blanking box resets, it gradually tilts, and the workpiece located inside the chute will fall down, preventing the workpiece from blocking the chute. In addition, the conveying component is set up so that the workpiece falls above the conveyor belt. When the blanking box rotates, it drives the conveyor roller to rotate, thereby conveying the workpiece that falls above the conveyor belt, avoiding collision between the falling workpiece and the workpiece above the conveyor belt. Moreover, it is not necessary for personnel to catch the falling workpiece by hand. When a certain number of workpieces accumulate above the conveyor belt, personnel put them into the blanking box, reducing damage caused by collision between parts.

[0007] The invention is further configured such that a baffle plate is fixed to one side of the top of the material box, and the baffle plate is made of rubber.

[0008] Preferably, the baffle plate can block the workpiece when it falls, preventing it from falling to the ground and causing damage. The baffle plate made of rubber can protect the workpiece.

[0009] The present invention is further configured such that the conveying assembly includes a conveyor belt and conveyor rollers, two sets of the conveyor rollers are movably installed inside the material box, and the outer wall of the conveyor rollers is fitted with a conveyor belt.

[0010] Preferably, the conveying component can convey the workpiece, avoiding the problem of workpieces accumulating at the drop port and causing collisions, and also eliminating the need for the user to manually catch the falling workpieces.

[0011] The present invention is further configured such that the transmission assembly includes a first synchronous pulley, a synchronous belt, and a second synchronous pulley, the end of the transmission roller is fixed with the first synchronous pulley, the end of the transmission rod is fixed with the second synchronous pulley, and the outer walls of the second synchronous pulley and the first synchronous pulley are fitted with synchronous belts.

[0012] Preferably, when the transmission rod rotates, it drives the second synchronous pulley to rotate. When the second synchronous pulley rotates, it drives the first synchronous pulley to rotate under the action of the synchronous belt. The rotation of the first synchronous pulley drives the conveyor roller to rotate.

[0013] The present invention is further configured such that the diameter of the second synchronous pulley is twice the diameter of the first synchronous pulley, and the second synchronous pulley and the first synchronous pulley are toothed synchronous pulleys, and the synchronous belt is a toothed synchronous belt.

[0014] Preferably, when the second synchronous pulley rotates one revolution, the first synchronous pulley rotates two revolutions, thereby enabling the workpiece located above the conveyor belt to move away from the discharge port.

[0015] The present invention is further configured such that a protective shell is fixed to one side of the material box, and a groove is provided inside the protective shell; multiple sets of fixing rods are fixed to one side of the protective shell, and the fixing rods are fixedly connected to the body of the dual-spindle sliding core machine.

[0016] Preferably, the protective shell can protect the first and second synchronous pulleys, preventing them from being exposed to the outside, which could easily lead to accidental injury to personnel.

[0017] The invention is further configured such that a mounting plate is fixed to one side of the material box, and a movable groove is provided on one side of the mounting plate. A vertical plate is movably installed inside the movable groove, and a spring is fixed to the bottom of the vertical plate.

[0018] Preferably, when the material box rotates, it will squeeze the vertical plate, which slides inside the moving groove and squeezes the spring at the same time. The top of the vertical plate is always in contact with the bottom of the material box. By setting the vertical plate to always be in contact with the bottom of the material box, it is possible to prevent debris from entering the material box and the top of the conveyor belt.

[0019] The present invention is further configured such that one side of the top of the mounting plate is inclined, and the end of the vertical plate is arc-shaped.

[0020] Preferably, the top of the mounting plate with a sloping surface can prevent debris from accumulating on top, making it easier to clean up the debris later. The curved end of the vertical plate can reduce the friction between the vertical plate and the bottom of the material box.

[0021] The present invention is further configured such that the width of the vertical plate is greater than the width of the bottom of the material drop box.

[0022] Preferably, it can better block debris and prevent debris from entering the interior of the mounting groove.

[0023] In summary, the present invention has the following main beneficial effects:

[0024] This invention features a feeding box, a telescopic rod, a chute, and a conveying assembly. When the secondary shaft processes a workpiece, the telescopic rod pushes the feeding box to rotate, ensuring it fits snugly against the inner wall of the dual-spindle sliding head machine body, preventing debris from splashing into the chute. When unloading is required, the telescopic rod rotates the feeding box to a certain angle, facilitating workpiece entry. As the feeding box resets, it gradually tilts, allowing workpieces in the chute to fall, preventing blockage. The conveying assembly ensures workpieces fall above the conveyor belt, and the rotating feeding box drives the conveyor rollers to transport these works, preventing collisions between falling and existing workpieces. Furthermore, it eliminates the need for manual handling of falling workpieces. Once a certain number of workpieces accumulate above the conveyor belt, they are placed into the feeding box, minimizing damage from collisions.

[0025] This invention incorporates a mounting plate, a vertical plate, a spring, and a baffle plate. The vertical plate contacts the bottom of the material box, preventing debris from falling into the box and onto the conveyor belt. The baffle plate cushions the falling workpieces, preventing them from hitting the ground. The protective shell protects the transmission components, preventing them from being exposed and causing accidental injury to personnel. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of the present invention will now be described.

[0039] Please see Figures 1-9 The machine includes a dual-spindle sliding headstock body 1, a material box 5 movably mounted inside the dual-spindle sliding headstock body 1, and a feed inlet 51 on one side of the material box 5. The machine body 1 has an internal mounting groove, and the material box 5 is movably mounted inside the mounting groove. The material box 5 is made of plastic and has an internal sliding groove 52. Rotating rods 53 are fixed to both sides of the material box 5. A drive assembly is located at the bottom of the material box 5, and a first bevel gear 54 is fixed to the end of the rotating rod 53. A material box 2 is fixed to one side of the dual-spindle sliding headstock body 1, and a conveying assembly 3 is located inside the material box 2. A connecting rod 7 is movably mounted inside the dual-spindle sliding headstock body 1, and a second bevel gear 71 is fixed to the end of the connecting rod 7. A one-way... The bearing 72 has a sleeve 81 fitted on its outer wall. A transmission rod 8 is fixed on one side of the sleeve 81. The transmission rod 8 is connected to the transmission assembly 3 through the transmission assembly. The drive assembly includes a telescopic rod 6 and a fixed block 61. The bottom of the telescopic rod 6 is movably connected to the inside of the double spindle sliding core machine body 1. The output end of the telescopic rod 6 is fixed with the fixed block 61, and the fixed block 61 is movably connected to the bottom of the dropping box 5. The output end of the telescopic rod 6 retracts, thereby driving the dropping box 5 to rotate. The dropping box 5 rotates around the rotating rod 53 as the center, which in turn drives the rotating rod 53 to rotate (when the rotating rod 53 rotates, it drives the first bevel gear 54 to rotate, when the first bevel gear 54 rotates, it drives the connecting rod 7 to rotate, and when the connecting rod 7 rotates, it drives the one-way bearing 72 to rotate freely). The tilt angle of the dropping box 5 gradually decreases.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 4 A baffle plate 21 is fixed on one side of the top of the material box 2. The baffle plate 21 is made of rubber. The baffle plate 21 can block the workpiece when it falls, preventing the workpiece from falling to the ground and causing damage. The rubber baffle plate 21 can protect the workpiece.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The conveying component 3 includes a conveyor belt 31 and a conveyor roller 32. Two sets of conveyor rollers 32 are movably installed inside the material box 2, and the outer wall of the conveyor roller 32 is fitted with a conveyor belt 31. The conveying component 3 can convey the workpiece, avoiding the problem of workpieces accumulating at the drop port and causing collisions, and also eliminating the need for the user to catch the falling workpieces by hand.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The transmission assembly includes a first synchronous pulley 33, a synchronous belt 34, and a second synchronous pulley 82. The first synchronous pulley 33 is fixed to the end of the transmission roller 32, and the second synchronous pulley 82 is fixed to the end of the transmission rod 8. The outer walls of the second synchronous pulley 82 and the first synchronous pulley 33 are fitted with a synchronous belt 34. When the transmission rod 8 rotates, it will drive the second synchronous pulley 82 to rotate. When the second synchronous pulley 82 rotates, it will drive the first synchronous pulley 33 to rotate under the action of the synchronous belt 34. The rotation of the first synchronous pulley 33 will drive the transmission roller 32 to rotate, reducing the use of a motor.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The diameter of the second synchronous pulley 82 is twice the diameter of the first synchronous pulley 33. Both the second synchronous pulley 82 and the first synchronous pulley 33 are toothed synchronous pulleys. The synchronous belt 34 is a toothed synchronous belt. The diameter of the second synchronous pulley 82 is twice the diameter of the first synchronous pulley 33. When the second synchronous pulley 82 rotates once, the first synchronous pulley 33 will rotate twice, thereby enabling the workpiece located above the conveyor belt to move away from the discharge port.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 6 A protective shell 4 is fixed to one side of the material box 2, and a groove is provided inside the protective shell 4. Multiple sets of fixing rods 41 are fixed to one side of the protective shell 4, and the fixing rods 41 are fixedly connected to the body 1 of the double spindle sliding core machine. The protective shell 4 can protect the first synchronous wheel 33 and the second synchronous wheel 82, preventing them from being exposed to the outside, which could easily lead to accidental injury to personnel.

[0045] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 and Figure 9A mounting plate 9 is fixed to one side of the material box 2, and a moving groove 92 is provided on one side of the mounting plate 9. A vertical plate 91 is movably installed inside the moving groove 92, and a spring 93 is fixed to the bottom of the vertical plate 91. When the material box 5 rotates, it will squeeze the vertical plate 91. The vertical plate 91 slides inside the moving groove 92 and squeezes the spring 93 at the same time. The top of the vertical plate 91 is always in contact with the bottom of the material box 5. By setting the vertical plate 91, it can always be in contact with the bottom of the material box 5, thereby preventing debris from entering the material box and falling above the conveyor belt.

[0046] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The top of the mounting plate 9 has a sloping side, and the end of the vertical plate 91 has an arc shape. The sloping top of the mounting plate 9 can prevent debris from accumulating on top, making it easier to clean up the debris later. The arc shape at the end of the vertical plate 91 can reduce the friction between the vertical plate 91 and the bottom of the drop box 5.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The width of the vertical plate 91 is greater than the width of the bottom of the discharge box 5, which can better block debris and prevent debris from entering the interior of the mounting slot.

[0048] In practical operation, the dual-spindle Swiss-type machining center 1 begins operation, with the main spindle and secondary spindle working simultaneously. After the tool finishes machining the workpiece on the secondary spindle, the CNC program controls the secondary spindle to move towards the blanking box. At this time, the telescopic rod 6 operates, and its output end retracts, thereby driving the blanking box 5 to rotate. The blanking box 5 rotates around the rotating rod 53, which in turn drives the rotating rod 53 to rotate. (When the rotating rod 53 rotates, it drives the first bevel gear 54 to rotate, which in turn drives the connecting rod 7 to rotate, which in turn drives...) (When the moving one-way bearing 72 is idling), the tilt angle of the dropping box 5 gradually decreases. When the dropping box 5 rotates, it will squeeze the vertical plate 91. The vertical plate 91 slides inside the moving groove 92 and squeezes the spring 93 at the same time. The top of the vertical plate 91 is always in contact with the bottom of the dropping box 5. Then the telescopic rod 6 stops working. At this time, the secondary shaft approaches the dropping box and drives the workpiece to approach the feed port 51 until the workpiece is completely inside the feed port 51. Then the secondary shaft releases the workpiece, and the workpiece will fall into the slide 52. Then the secondary shaft begins to move away from the dropping box 5.

[0049] When the secondary shaft moves away from the material box 5, the telescopic rod 6 operates, extending its output end and causing the material box 5 to continue rotating. The material box 5 rotates around the rotating rod 53, simultaneously causing the rotating rod 53 to rotate. The rotation of the rotating rod 53 drives the first bevel gear 54 to rotate, which in turn drives the second bevel gear 71 meshing with it to rotate. The rotation of the second bevel gear 71 drives the connecting rod 7 to rotate, which in turn drives the one-way bearing 72 to rotate. At this time, the one-way bearing 72 causes the retaining sleeve 81 to rotate. Rotation 1 will drive transmission rod 8 to rotate. At this time, the rotation of transmission rod 8 will drive the second synchronous pulley 82 to rotate. When the second synchronous pulley 82 rotates, it will drive the first synchronous pulley 33 to rotate under the action of synchronous belt 34. The rotation of the first synchronous pulley 33 will drive the conveyor roller 32 to rotate. The rotation of the conveyor roller 32 will drive the conveyor belt 31 to drive. The conveyor belt 31 will convey the workpiece located above it. When the tilt angle of the drop box 5 gradually increases, the workpiece located inside the chute 52 will slide down under its own gravity and fall above the conveyor belt 31.
