Description

Technical Field

[0001] This utility model relates to the field of transportation and transfer equipment technology, and in particular to an electric cylinder gripper mechanism. Background Technology

[0002] In the stacking stage of a block forming machine, the gripper mechanism plays a crucial role. Traditional stacking gripper mechanisms mostly use pneumatic or hydraulic drives. Although pneumatic drives have a fast response speed, their output force is relatively small, making it difficult to stably grip some heavy blocks. Furthermore, when the air source pressure is unstable, the gripping force fluctuates significantly, which can easily cause blocks to fall, posing a safety hazard. Hydraulic drives can provide greater output force, but their system structure is complex and requires a dedicated hydraulic station, resulting in higher costs. Hydraulic oil leaks can also cause environmental pollution. In addition, when gripping blocks of different sizes, traditional grippers often require manual adjustment of the gripper spacing, which is cumbersome, inefficient, and difficult to meet the high-efficiency and automated requirements of modern block production. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides an electric cylinder gripper mechanism, which facilitates the adjustment of the gripper spacing, gripping force, and gripper opening and closing distance.

[0004] The technical solution adopted by this utility model is: an electric cylinder gripper mechanism, including a mounting frame and two pairs of grippers mounted on the mounting frame. The opening and closing directions of the two pairs of grippers are perpendicular. Each pair of grippers includes a guide post mounted on the mounting frame, two clamping plate assemblies slidably mounted on the guide post, and a drive electric cylinder for moving the clamping plate assemblies. The cylinder body end and piston rod end of the drive electric cylinder are respectively connected to the two clamping plate assemblies. The clamping plate assembly includes a slider slidably fitted on the guide post, a clamping plate connected below the slider, and an adjusting rod connected to the top of the slider. The cylinder body end or piston rod end of the drive electric cylinder is connected to the corresponding adjusting rod. The position of the adjusting rod is adjustable and mounted on the slider.

[0005] Preferably, the slider has multiple sets of adjustment holes along its axial direction, and the adjustment rod is connected to one set of adjustment holes by locking bolts.

[0006] Preferably, a synchronization mechanism is provided between each pair of grippers. The synchronization mechanism includes a rack and a synchronization gear rotatably mounted on the mounting frame. The synchronization gear is engaged with two racks, which mesh with the upper and lower sides of the synchronization gear respectively. The corresponding two racks are connected to the sliders of the two clamping plate assemblies respectively.

[0007] Preferably, the bottom of the slider is connected to a connecting frame, and the clamping plate can be detachably installed on the connecting frame.

[0008] Preferably, the lower end of the connecting frame is connected to a hanging plate, and the clamp is provided with a hook, and the clamp is hung on the hanging plate by the hook.

[0009] Preferably, multiple hooks are installed in pairs on the clamping plate, and each pair of hooks has a positioning protrusion on the hanging plate on both sides, the positioning protrusion abutting against the corresponding hook.

[0010] Preferably, the clamp is provided with a rubber strip.

[0011] The beneficial effects of this utility model are as follows: The electric cylinder driving the electric cylinder of the electric cylinder gripper mechanism of this utility model can accurately control the output force and displacement, and can accurately adjust the gripping force and gripper opening and closing distance according to the weight and specifications of different blocks, which greatly improves the stability and accuracy of gripping and reduces the risk of blocks falling.
