Description

Technical Field

[0001] This utility model relates to the field of machine tool processing equipment, and in particular to a loading and unloading mechanism for machining eccentric parts. Background Technology

[0002] With the popularization of intelligent manufacturing technology, the precision eccentric component machining field has achieved fully automated operation. For irregularly shaped eccentric parts with asymmetrical structures (where the two cylindrical ends have axial offsets and require machining different features separately), the existing machining system adopts a dual-clamping station collaborative scheme: first, the left end feature is clamped and machined by the right station, and then the system switches to the left station to machine the right end feature. However, the current loading and unloading process still relies on manual operation, which has two major drawbacks: first, operators need to intervene in high-risk work areas during equipment operation breaks; second, manual intervention leads to a production line cycle time loss of more than 30%. Utility Model Content

[0003] To address the shortcomings of the existing technology, the main objective of this utility model is to overcome these deficiencies and disclose a loading and unloading mechanism for machining eccentric parts. The mechanism includes a mounting base, a first connecting member, a second connecting member, a gripper assembly, a first driving assembly, and a second driving assembly. The mounting base is mounted on the first driving assembly, which drives the mounting base to move horizontally and rotate. The first connecting member is mounted on the mounting base, and the second connecting member is mounted on the mounting base via the second driving assembly. Two sets of gripper assemblies are provided, one on the first connecting member and the other on the second connecting member. The second driving assembly drives the second connecting member to move horizontally.

[0004] Furthermore, the first drive assembly includes a linear module and a rotary cylinder, the rotary cylinder being disposed on the linear module and the mounting base being disposed on the rotary cylinder.

[0005] Furthermore, the linear module is a ball screw slide or a synchronous belt slide.

[0006] Furthermore, the second drive assembly includes a cylinder, a guide rail, a slider, and a support. The support is fixed on the mounting base, and the cylinder and the slider are disposed on the support. The second connecting member is slidably connected to the slider through the guide rail, and the cylinder is connected to the second connecting member, providing a reciprocating driving force for the second connecting member through the cylinder.

[0007] Furthermore, a limiting block is installed at one end of the guide rail.

[0008] Furthermore, a buffer pad is provided on the support, and the position of the buffer pad corresponds to that of the limiting block.

[0009] Furthermore, the second connecting member includes a fixing plate, an adjusting plate, and a connecting plate. The fixing plate is disposed on the second driving assembly, and the connecting plate is fixedly connected to the adjusting plate. An adjusting hole is provided parallel to the connecting plate, and a bolt passes through the adjusting hole to connect to the fixing plate.

[0010] Furthermore, the connecting plate is recessed with an adjustment groove that matches the dimensions of the fixing plate and the adjustment plate.

[0011] Furthermore, the fixing plate is provided with a guide groove, the connecting plate is provided with an adjustment hole, the adjusting bolt is provided with a guide plate, the adjusting bolt is threadedly engaged with the adjustment hole, and the guide plate is placed in the guide groove.

[0012] Furthermore, the gripper assembly includes a gripper cylinder and grippers disposed on the gripper cylinder.

[0013] The beneficial effects achieved by this utility model are: This invention combines a linear module of the first drive assembly with a rotary cylinder to achieve a composite drive for the horizontal and rotary movements of the mounting base. In conjunction with the second drive assembly, it enables the loading and unloading of parts, significantly improving work efficiency while preventing workers from entering high-risk work areas. Through the combined design of the adjusting plate, guide groove, and adjusting bolts, the length of the second connecting piece can be adjusted within a range of ±15mm, simplifying the adjustment process and enhancing its adaptability.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] A loading and unloading mechanism for machining eccentric parts includes a mounting base 1, a first connecting member 2, a second connecting member 3, a gripper assembly 4, a first drive assembly 5, and a second drive assembly 6. The mounting base 1 is mounted on the first drive assembly 5, which drives the mounting base 1 to move horizontally and rotate. The first connecting member 2 is mounted on the mounting base 1, and the second connecting member 3 is mounted on the mounting base 1 via the second drive assembly 6. Two sets of gripper assemblies 4 are provided, one on the first connecting member 2 and the other on the second connecting member 3. The second drive assembly 6 drives the second connecting member 3 to move horizontally. The first drive assembly controls the mounting base 1 to move the first connecting member 2 towards the part to be machined, so that the gripper assembly 4 on the first connecting member 2 can grip the part to be machined. Then, the first drive assembly 5 moves the part to a designated position and rotates it to the loading position. At this time, the gripper assembly 4 on the second connecting member 2 corresponds to the unloading position. The second drive assembly 6 controls the gripper assembly 4 on the second connecting member 3 to move horizontally to hold the machined part. After the second drive assembly 6 resets, the first drive assembly 5 rotates and resets to remove the part from the high-risk operation area. The processed parts can then be removed manually or by a material handling device, and the loading and unloading mechanism is ready for the next loading and unloading operation.

[0017] In one embodiment, the first drive assembly 5 includes a linear module 51 and a rotary cylinder 52. The rotary cylinder 52 is mounted on the linear module 51, and the mounting base 1 is mounted on the rotary cylinder 52. The linear module 51 drives the rotary cylinder 52 to reciprocate, and the rotary cylinder 52 drives the mounting base 1 to rotate reciprocally.

[0018] In the above embodiments, the linear module 51 is a ball screw slide or a synchronous belt slide.

[0019] In one embodiment, the second drive assembly 6 includes a cylinder 61, a guide rail 62, a slider 63, and a support 64. The support 64 is fixed on the mounting base 1. The cylinder 61 and the slider 63 are disposed on the support 64. The second connecting member 3 is slidably connected to the slider 63 via the guide rail 62; that is, the guide rail 62 and the slider 63 are slidably connected, and the second connecting member 3 is fixedly mounted on the guide rail 62. The cylinder 61 is connected to the second connecting member 3, and the cylinder 61 provides a reciprocating driving force for the second connecting member 3.

[0020] In the above embodiment, a limiting block 65 is installed at one end of the guide rail 62. The limiting block 65 limits the maximum extension distance of the second connector 3.

[0021] In the above embodiment, a buffer pad 66 is provided on the support 64, and the buffer pad 66 corresponds to the position of the limiting block 65. This prevents the limiting block 65 from directly impacting the slider 63 and causing damage, and reduces impact noise.

[0022] In one embodiment, the second connecting member 3 includes a fixing plate 31, an adjusting plate 32, and a connecting plate 33. The fixing plate 31 is disposed on the second drive assembly 6, and the connecting plate 33 is fixedly connected to the adjusting plate 32. An adjusting hole 331 is provided parallel to the connecting plate 33, and a bolt passes through the adjusting hole 331 to connect with the fixing plate 31. Specifically, the adjusting plate 32 and the fixing plate 31 are provided with screw holes for locking. The adjusting plate is provided with a through hole and the adjusting hole 331. The bolt passes through the through hole and is fixed to the screw hole of the adjusting plate 32 to achieve the fixation of the adjusting plate 32 and the connecting plate 33. The bolt passes through the adjusting hole 331 to fix the fixing plate 31. The overall length of the second connecting member 3 can be adjusted using the adjusting hole 32.

[0023] In the above embodiment, the connecting plate 33 is recessed with an adjustment groove 332 that matches the dimensions of the fixing plate 31 and the adjusting plate 32. The adjustment groove 332 serves to fix the adjusting plate 32, ensuring that the adjusting plate 32 and the connecting plate 33 remain relatively stationary. The adjustment groove 332 also serves to guide the fixing plate 31, limiting its position adjustment to the length direction only.

[0024] In the above embodiment, a guide groove 311 is provided on the fixed plate 31, an adjustment hole is provided on the connecting plate 33, and a guide plate 71 is provided on the adjusting bolt 7. The adjusting bolt 7 is threadedly engaged with the adjustment hole, and the guide plate 71 is placed in the guide groove 311. The guide groove 311 guides the guide plate 71 to rotate and restricts the axial movement of the adjusting bolt 7. The connecting plate 33 is moved by rotating the adjusting bolt 7.

[0025] In one embodiment, the gripper assembly 4 includes a gripper cylinder 41 and grippers 42 disposed on the gripper cylinder 41. In this embodiment, a three-jaw cylinder is selected for the gripper cylinder 41, which can improve the stability of workpiece clamping.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model.
