Description

Technical Field

[0001] This utility model relates to the field of valve processing equipment technology, and in particular to a lathe gantry double-axis valve loading and unloading device. Background Technology

[0002] The lathe gantry dual-axis valve loading and unloading device is an automated mechanical structure used to automatically load, position, unload, and transfer valve workpieces during lathe machining. By replacing manual labor with automated operation, it accurately and efficiently completes the transfer and clamping of valves between lathe workstations, thereby improving production efficiency, reducing labor intensity, and ensuring the consistency and safety of the machining process. It is suitable for intelligent manufacturing scenarios of mass valve machining.

[0003] The lathe gantry dual-axis valve loading and unloading device is an automated loading and unloading structure, which is usually composed of a gantry robot, a dual-axis drive assembly and a valve clamping mechanism.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a lathe gantry dual-axis valve loading and unloading device, including a vertical rod 1, which provides stable support for the entire device and ensures that there is no shaking during high-speed operation. A drive arm 2 is installed at the top of the vertical rod 1, which can move in multiple directions and provide precise displacement control for the clamping part. A quick-change mechanism 3 is fixedly connected to the front end of the drive arm 2, which can significantly shorten the replacement time of the clamping part and improve the adaptability of the equipment. A sliding platform 4 is placed on the outside of the vertical rod 1, which can be flexibly adjusted to facilitate the loading and unloading of valve workpieces of different specifications. A protective mechanism 5 is placed on the outside of the sliding platform 4, which can effectively isolate the working area and prevent personnel from directly contacting dangerous parts.

[0035] The quick-change mechanism 3 includes two rotating blocks 31. The front end of the drive arm 2 is fixedly connected to the rear end of the two rotating blocks 31. The two rotating blocks 31 can rotate at multiple angles, allowing the clamping part to adapt to different gripping angles. This double rotating block 31 design enhances the stability of the connection and prevents the clamping part from shifting during operation. The front end of each of the two rotating blocks 31 is fixedly connected to a fixing block 32. A button 34 is slidably connected inside the fixing block 32. The button 34 provides a convenient operating interface for the operator, making it easy to quickly trigger the replacement action of the clamping part. A fixing rod 35 is fixedly connected to the rear end of the button 34. A quick-lock assembly 36 is fixedly connected to the rear end of the fixing rod 35. The quick-lock assembly 36 is the core component for realizing the quick fixing and release of the clamping part, ensuring the high efficiency of clamping part replacement.

[0036] The quick-clamp assembly 36 has two grooved posts 37 slidably connected to its inner side. Alignment blocks 33 are fixedly connected to the outer sides of the two grooved posts 37. A gripper 38 is fixedly connected to the rear end of the alignment block 33. The alignment block 33 can ensure that the gripper 38 is precisely aligned with the fixing block 32 during installation, thereby improving the installation accuracy. The gripper 38 directly contacts the valve workpiece. Its structural design can ensure stable clamping of valve workpieces of different specifications. The cooperation between the two grooved posts 37 and the quick-clamp assembly 36 can realize the rapid positioning and fixing of the gripper 38.

[0037] The front end of the protective mechanism 5 is equipped with an auxiliary component 59. The quick-lock component 36 includes a locking block 361. The rear end of the fixing rod 35 is fixedly connected to the front end of the locking block 361. The locking block 361 can be locked into the recessed part of the groove post 37 to fix the gripper 38 and ensure that the locking block 361 moves synchronously with the fixing rod 35 to ensure the accuracy of the action. The rear end of the locking block 361 is fixedly connected with three springs 362. The three springs 362 can provide a stable restoring force for the locking block 361 to ensure reliable engagement between the locking block 361 and the groove post 37.

[0038] The outer side of the grooved post 37 is slidably connected to the inside of the fixing block 32. This sliding connection facilitates the insertion and removal of the grooved post 37, enabling quick replacement of the gripper 38. The inside of the fixing block 32 is slidably connected to the outer side of the fixing rod 35, ensuring that the fixing rod 35 slides smoothly within the fixing block 32 and ensuring smooth operation of the button 34. The outer side of the locking block 361 is slidably connected to the inside of the fixing block 32, allowing the locking block 361 to move flexibly within the fixing block 32, enabling engagement and release of the grooved post 37. Multiple springs 362 are sleeved inside the fixing block 32, providing a stable installation space for the springs 362 and ensuring their normal elastic function. The inner side of the locking block 361 is slidably connected to the outer side of the grooved post 37, allowing the locking block 361 to accurately engage with the recessed part of the grooved post 37, achieving reliable fixation. The front end of the fixing block 32 is slidably connected to the rear end of the alignment block 33, ensuring precise fit between the alignment block 33 and the fixing block 32, and improving the accuracy of the gripper 38 installation.

[0039] Reference Figure 1 , Figure 4 and Figure 5The protective mechanism 5 includes an outer protective plate 51. The outer side of the sliding platform 4 is placed inside the outer protective plate 51. The outer protective plate 51 can block flying debris during operation, protect the safety of the operator, and surround the sliding platform 4 in the protective area to form an effective safety barrier. A curved plate 53 is fixedly connected to the outer side of the outer protective plate 51. A protrusion plate 54 is fixedly connected to the front end of the curved plate 53. Two limit blocks 55 are rotatably connected to the outer side of the protrusion plate 54. A cylinder 56 is installed at the rear end of each of the two limit blocks 55. The curved plate 53 provides an installation position for the cylinder 56 and other components, making the structure of the protective mechanism 5 more compact. The protrusion plate 54 provides a rotation fulcrum for the limit blocks 55, ensuring the normal operation of the limit blocks 55. The two limit blocks 55 can limit the movement range of the cylinder 56 to ensure that the opening and closing angle meets the safety requirements.

[0040] A shift block 57 is fixedly connected to the drive end of the cylinder 56. A connecting block 58 is rotatably connected inside the shift block 57. A quick-opening door 52 is fixedly connected to the rear end of the connecting block 58. The cylinder 56 provides power for the opening and closing of the quick-opening door 52 to realize automated control. The shift block 57 can transmit the driving force of the cylinder 56 to the connecting block 58 to drive the quick-opening door 52 to move. The connecting block 58 can convert the linear motion of the shift block 57 into the rotational motion of the quick-opening door 52 to realize the opening and closing of the quick-opening door 52. When the quick-opening door 52 is open, it is convenient for the operator to pick up and put down the workpiece. When closed, it forms a closed protective space.

[0041] The auxiliary component 59 includes two auxiliary blocks 591. The front end of the quick-opening door 52 is fixedly connected to the two auxiliary blocks 591. The bottom end of each of the two auxiliary blocks 591 is rotatably connected to a support block 592. The two auxiliary blocks 591 provide mounting points for the support block 592, ensuring the structural stability of the auxiliary component 59. The auxiliary component 59 can assist the opening and closing action of the quick-opening door 52, making the opening and closing process smoother. It can also make the auxiliary blocks 591 move synchronously with the quick-opening door 52, ensuring the effectiveness of the auxiliary function. The support block 592 can limit the movement trajectory of the quick-opening door 52, making the opening and closing action smoother. The support block 592 is rotatably connected to a rotating rod 593 inside.

[0042] An auxiliary component 59 is fixedly connected to the front end of the quick-opening door 52 to enhance the stability of the opening and closing process of the quick-opening door 52. The rear end of the support block 592 is fixedly connected to the front end of the outer protective plate 51, so that the auxiliary component 59 and the outer protective plate 51 form a whole, improving the stability of the structure. The front end of the outer protective plate 51 is rotatably connected to the rear end of the quick-opening door 52 to ensure that the quick-opening door 52 can rotate flexibly and realize the opening and closing function.

[0043] Working principle: When the device clamps and loads valve workpieces, situations may arise where the clamping components are damaged or valve workpieces of various specifications are encountered during use. In such cases, the quick-change mechanism 3 can be used to quickly replace the gripper 38 to speed up the operation. The user can quickly disassemble the gripper 38 by using the grooved post 37 connected in the middle of the alignment block 33 fixed at the bottom of the gripper 38. By pressing the button 34 on the outside of the fixing block 32, the button 34 moves inward, causing the fixing rod 35 to slide inside the fixing block 32, which in turn causes the locking block 361 to move backward and squeeze the spring 362. At this time, since the locking block 361 no longer engages with the recessed part of the grooved post 37, the disassembly effect is achieved. The reinstalled gripper 38, due to the rebound action of the spring 362, causes the locking block 361 to spring back and engage with the recessed part of the grooved post 37, thus achieving fixation.

[0044] To ensure overall safety during personnel interaction with the equipment and direct protection during material handling, a protective mechanism 5 is used for safety protection. A large number of valve workpieces placed on the sliding platform 4 will be pushed to the rear end after processing. At this time, the user only needs to open the cylinder 56. The cylinder 56 retracts and drives the front displacement block 57 to move backward together. The connecting block 58 inside the displacement block 57 moves outward and drives the quick-opening door 52 to open. As the cylinder 56 pulls inward, it will also move towards the outside of the curved plate 53 due to its action. The auxiliary block 591 at the front end of the outer guard plate 51 rotates on the top of the support block 592 to assist in opening and closing the quick-opening door 52.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
