Description

Technical Field

[0001] This invention relates to the field of machining center technology, and more specifically, to a precision machining center that improves machining efficiency. Background Technology

[0002] A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for machining complex parts. It is one of the world's most produced and widely used CNC machine tools, possessing strong comprehensive machining capabilities. A single workpiece clamping operation can complete a significant amount of machining, achieving high precision. For batches of workpieces with moderate machining difficulty, its efficiency is several times that of ordinary equipment. In particular, it can perform many machining operations that ordinary equipment cannot, making it especially suitable for single-piece machining or small-batch, multi-variety production with complex shapes and high precision requirements. It integrates milling, boring, drilling, tapping, and thread cutting functions into a single machine, enabling it to employ multiple processing methods. Machining centers are classified according to the spatial position of the spindle during machining: horizontal and vertical machining centers. However, currently, the mounting of workpieces on machining centers is done manually, resulting in low installation efficiency and high labor intensity, severely hindering the improvement of CNC machining center efficiency.

Detailed Implementation

[0033] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and by way of embodiments. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0034] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" in this article describes another type of relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0035] according to Figures 1-11As shown, a precision machining center for improving processing efficiency includes a workpiece transporter and a workpiece mounting component. The workpiece transporter is located on the ground next to the machining center, and the workpiece mounting component is located on the machining center. The workpiece transporter includes a support steering component and a workpiece gripper, with the workpiece gripper mounted on the support steering component. The support steering component includes a support component and a steering component, with the steering component mounted on the support component. The support component includes a support plate 1, a support shaft 2, a support rod 3, a first motor 4, a first worm gear 5, and a first worm wheel 6. The support plate 1 is located on the ground. Both ends of the support shaft 2 are provided with support mounting seats 7, allowing the support shaft 2 to rotate circumferentially on the support mounting seats 7. The support shaft 2 is fixedly mounted on the support plate 1 via the two support mounting seats 7. One end of the support rod 3 is vertically fixed on one end of the support shaft 2, and two support rods 3 are symmetrically arranged on both ends of the support shaft 2 to support the steering component. The first motor 4 is fixedly mounted on the support plate 1, the first worm gear 5 is fixedly mounted on the shaft of the first motor 4, and the first worm wheel 6 is fixedly mounted on one end of the support shaft 2, and the first worm wheel 6 meshes with the first worm gear 5. When the first motor 4 drives the first worm gear 5 to rotate, it will drive the support shaft 2 to rotate circumferentially on the support mounting base 7 through the first worm wheel 6.

[0036] The steering component includes a steering shaft 8, a steering rod 9, a second motor 10, a second worm gear 39, and a second worm wheel 40. Both ends of the steering shaft 8 are provided with steering mounting seats 11, allowing the steering shaft 8 to rotate circumferentially within the steering mounting seats 11. Each steering mounting seat 11 is correspondingly mounted on the other end of the support rod 3, and the axis of the steering shaft 8 is parallel to the axis of the support shaft 2. One end of the steering rod 9 is vertically fixed to one end of the steering shaft 8, and two steering rods 9 are symmetrically distributed at both ends of the steering shaft 8 to support the workpiece gripper. The second motor 10 is fixedly mounted on the support rod 3, the second worm gear 39 is fixedly mounted on the shaft of the second motor 10, and the second worm wheel 40 is fixedly fitted onto one end of the steering shaft 8, meshing with the second worm gear 39. When the second motor 10 drives the second worm gear 39 to rotate, it will drive the steering shaft 8 to rotate circumferentially through the second worm wheel 40. The steering shaft 8 will drive the other end of the steering rod 9 to swing perpendicular to the axis of the steering shaft 8, thereby driving the workpiece gripper to grip and transport the workpiece to be processed onto the workpiece mounting piece.

[0037] The workpiece gripping component includes a gripping support and a gripping member. The gripping support is mounted on the steering member, and the gripping member is mounted on the gripping support. The gripping support includes a gripping support shaft 12 and a gripping support ring 13. The gripping support shaft 12 is tubular, and a gripping support seat is fitted onto the gripping support shaft 12. The gripping support shaft 12 can rotate circumferentially within the gripping support seat, and the gripping support seat is fixedly mounted on the other end of the steering rod 9. There are two gripping support shafts 12, each corresponding to one of the two steering rods 9, and the axes of the two gripping support shafts 12 coincide. The gripping support ring 13 is rectangular, and its two sides are horizontally fixedly mounted on one end of the two gripping support shafts 12, so that the gripping support ring 13 is horizontal under non-external force.

[0038] The gripping components include a lateral gripping component and a longitudinal gripping component, both of which are mounted on the gripping support ring 13. The lateral gripping component includes a lateral sliding gripping component and a lateral gripping power component, both of which are mounted on the gripping support ring 13. The lateral sliding gripping component includes a lateral support plate 14, a lateral sliding shaft 15, and a lateral gripping claw 16. One side of the lateral support plate 14 is vertically fixed to one side of the gripping support ring 13, and two lateral support plates 14 are correspondingly mounted on both sides of the gripping support ring 13. Two lateral sliding shafts 15 are horizontally fixed to the two lateral support plates 14, and both lateral sliding shafts 15 are mounted on the lateral support plates 14. The transverse gripper 16 is L-shaped, with a sliding hole on one side. The transverse gripper 16 is fitted onto the two transverse sliding shafts 15 one-to-one through the two sliding holes, allowing it to slide laterally along the shafts. Two transverse grippers 16 are provided, symmetrically distributed at both ends of the transverse sliding shafts 15. Furthermore, the other side of the transverse gripper 16 has a slope, allowing the other end of the gripper 16 to be inserted under the workpiece when gripping it, thus improving gripping stability.

[0039] The lateral gripping power component includes a lateral screw 17, a third motor 18, a third worm gear, and a third worm wheel. The threads at both ends of the lateral screw 17 rotate in opposite directions. One end of the lateral screw 17 is fitted with a first nut on a lateral gripping claw 16 and then passes through a gripping support shaft 12. The other end of the lateral screw 17 is fitted with a second nut on another lateral gripping claw 16 and then passes through another gripping support shaft 12. The lateral screw 17 is capable of circumferential rotation within the gripping support shaft 12. The third motor 18 is fixedly mounted on the steering rod 9, the third worm gear is fixedly mounted on the third motor 18, and the third worm wheel is fixedly fitted onto one end of the lateral screw 17, meshing with the third worm gear. When the third motor 18 drives the third worm gear to rotate, it will drive the transverse screw 17 to rotate circumferentially within the gripping support shaft 12 via the third worm wheel. The circumferentially rotating transverse screw 17 will simultaneously drive the two transverse gripping claws 16 to move towards each other along the transverse sliding shaft 15 via the first nut and the second nut, thereby gripping the workpiece laterally. It should be noted that during the gripping process, one end face of the transverse gripping claw 16 will laterally clamp the workpiece, and the other end face of the transverse gripping claw 16 will be inserted below the bottom surface of the workpiece to lift it up, thereby improving gripping stability.

[0040] The longitudinal gripper includes a longitudinal sliding gripper and a longitudinal gripping transmission component. The longitudinal sliding gripper is mounted on the gripping support ring 13, and the longitudinal gripping transmission component is mounted on the longitudinal sliding gripper. The longitudinal sliding gripper includes a longitudinal support plate 19, a longitudinal sliding shaft 20, and a longitudinal gripping claw 21. One side of the longitudinal support plate 19 is vertically fixed on one end of the gripping support ring 13, and two longitudinal support plates 19 are correspondingly mounted on both ends of the gripping support ring 13. The length of the longitudinal sliding shaft 20 is greater than the length of the transverse sliding shaft 15, and both ends of the longitudinal sliding shaft 20 are horizontally fixed on the two longitudinal support plates 19. There are two longitudinal sliding shafts 20, both mounted on the longitudinal support plates 19. The longitudinal gripping claw 21 has the same structure as the transverse gripping claw 16. The longitudinal gripping claw 21 is mounted on the longitudinal sliding shaft 20, and the connection relationship between the longitudinal gripping claw 21 and the longitudinal sliding shaft 20 is the same as the connection relationship between the transverse gripping claw 16 and the transverse sliding shaft 15. This allows the two longitudinal gripping claws 21 to move towards each other to grip the workpiece along the longitudinal direction, thereby improving the gripping stability of the workpiece.

[0041] The longitudinal gripping transmission component includes a longitudinal screw 22, a first helical gear 23, a second helical gear 24, a transmission pin 25, and a spring 26. The length of the longitudinal screw 22 is greater than the length of the transverse screw 17. The threads at both ends of the longitudinal screw 22 rotate in opposite directions, and the thread pitch of the longitudinal screw 22 is greater than the thread pitch of the transverse screw 17. One end of the longitudinal screw 22 is fitted with a third nut on a longitudinal gripping claw 21 and then passes through one end of the gripping support ring 13. The other end of the longitudinal screw 22 is fitted with a fourth nut on another longitudinal gripping claw 21 and then passes through the other end of the gripping support ring 13. The longitudinal screw 22 can rotate circumferentially on the gripping support ring 13. The first helical gear 23 is fixedly mounted at the longitudinal center of the longitudinal screw 22. The second helical gear 24 is rotatably mounted on the transverse screw 17 and meshes with the first helical gear 23. The second helical gear 24 can rotate circumferentially on the transverse screw 17. One end of the transmission pin 25 is fitted into a transmission hole on the side wall of the transverse screw 17. The axis of the transmission hole is perpendicular to the axis of the transverse screw 17, and the depth of the transmission hole is greater than the length of the transmission pin 25, allowing the transmission pin 25 to slide axially back and forth within the transmission hole. The other end of the transmission pin 25 has a rounded corner surface, allowing it to be inserted into a rounded corner hole on the inner side of the second helical gear 24. The spring 26 is fitted into the transmission hole, with one end fixedly connected to the bottom of the transmission hole and the other end connected to one end of the transmission pin 25. The spring 26 can push the other end of the transmission pin 25 into the rounded corner hole. When the transverse screw 17 is driven to rotate by the third motor 18, it will drive the second helical gear 24 to rotate through the transmission pin 25. The second helical gear 24 will drive the first helical gear 23 to rotate. The first helical gear 23 will drive the longitudinal screw 22 to rotate. The rotating longitudinal screw 22 will drive the longitudinal gripping claw 21 to slide towards each other to clamp the workpiece longitudinally.It should be noted that, because the pitch of the longitudinal screw 22 is greater than the pitch of the transverse screw 17, even if the horizontal distance between the two longitudinal gripping claws 21 is greater than the horizontal distance between the two transverse gripping claws 16, the two longitudinal gripping claws 21 can still grip the longitudinal direction of the workpiece. When the pressure of the longitudinal gripping claws 21 on the workpiece exceeds a predetermined pressure, the longitudinal screw 22 will be unable to rotate, meaning the second helical gear 24 cannot drive the first helical gear 23 to rotate circumferentially. At this time, the transverse screw 17 is still rotating, and the second helical gear 24 will press against the rounded surface through the rounded hole, causing the transmission pin 25 to compress the spring 26 and retract into the transmission hole, thereby achieving relative rotation between the second helical gear 24 and the transverse screw 17. In this state, even if the longitudinal screw 22 stops rotating, it will not affect the rotation of the transverse screw 17, thus clamping the workpiece laterally.

[0042] The workpiece mounting component includes a mounting clamping component and a mounting top fastener. The mounting clamping component is mounted on the machining table 27 of the machining center, and the mounting top fastener is mounted on the mounting clamping component. The mounting clamping component includes a mounting plate 28, a transverse clamping component, and a longitudinal clamping component. The mounting plate 28 is fastened to the machining table 27 by T-bolts. The transverse clamping component includes a transverse sliding clamping component and a transverse clamping power component, both of which are mounted on the mounting plate 28. The transverse sliding clamping component includes a sliding rod 29 and a top fastener block 30. One end of the sliding rod 29 is provided with a sliding block, which is dovetail-shaped. The sliding rod 29 is fitted into a sliding groove on the top surface of the mounting plate 28 through the sliding block. The sliding groove is dovetail-shaped, allowing the sliding block to slide back and forth along its axial direction within the sliding groove. There are two sliding rods 29, which are parallel to each other on the mounting plate 28. The top fastening block 30 is rectangular in shape, with its two ends horizontally fixed to the other ends of the two sliding rods 29, and one side of the top fastening block 30 protruding horizontally from the side of the sliding rod 29. Two sets of transverse sliding clamping components are provided, symmetrically distributed on the transverse side of the mounting plate 28. The transverse clamping power component includes a transmission plate 31, a threaded rod 32, and a fourth motor 33. The transmission plate 31 is rectangular in shape and horizontally fixed to the sliding rod 29. The two transmission plates 31 correspond one-to-one with the two sets of transverse sliding clamping components. The threads at both ends of the threaded rod 32 rotate in opposite directions. One end of the threaded rod 32 is fitted into a first threaded hole on one transmission plate 31, and the other end is fitted into a second threaded hole on the other transmission plate 31. The fourth motor 33 is fixedly mounted on the mounting plate 28, and the free end of the shaft of the fourth motor 33 is fixedly connected to one end of the threaded rod 32. When the fourth motor 33 drives the threaded rod 32 to rotate in the forward direction, it will simultaneously drive the two transmission plates 31 to move towards each other through the first threaded hole and the second threaded hole, so as to clamp and fix the lateral sides of the workpiece to be processed transferred to the mounting top fastener.

[0043] The longitudinal clamping component includes a longitudinal sliding clamping component and a longitudinal clamping power component, both of which are mounted on the mounting plate 28. The longitudinal sliding clamping component has the same structure as the transverse sliding clamping component, and is positioned longitudinally on the mounting plate 28. The connection relationship between the longitudinal sliding clamping component and the mounting plate 28 is the same as that between the transverse sliding clamping component and the mounting plate 28. Two sets of longitudinal sliding clamping components are provided, symmetrically distributed longitudinally on the mounting plate 28. The longitudinal clamping power component has the same structure as the transverse clamping power component, and the connection relationship between the longitudinal clamping power component and the longitudinal sliding clamping component is the same as that between the transverse clamping power component and the transverse sliding clamping component. The two sets of longitudinal sliding clamping components can clamp and fix the workpiece on both longitudinal sides.

[0044] The mounting top fastener includes a guide rod 34, a lifting plate 35, a threaded tube 36, a threaded post 37, a fifth motor, a fourth worm gear, and a fourth worm wheel. One end of the guide rod 34 is vertically fixed at one corner of the mounting plate 28, and the four guide rods 34 are distributed one-to-one at the four corners of the mounting plate 28. The lifting plate 35 is provided with four guide through holes and eight sliding elongated through holes 38. The lifting plate 35 is fitted onto the other end of the guide rod 34 through the four guide through holes, allowing the lifting plate 35 to slide vertically back and forth along the guide rod 34 through the guide through holes.
