Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with specific embodiments, which are for explanation rather than limitation of the present invention.

[0034] Such as figure 1 with 2 As shown, the grasping mechanism of the present invention is mainly divided into two parts: one part is the hook grasping block assembly installed on the part to be grasped, and the other part is the hook base assembly installed on the manipulator. The piece to be grabbed is the load. The pallet grabbing device of the present invention includes: a mounting plate 2, a hook base 3, a screw 4, a positioning pin 5, a screw 6, a photoelectric sensor 7, a first screw 8, a hook grab block 9, and a lock nut 10 and hook claw positioning block 11. The piece to be grasped can be a workpiece or a quick-change tray 1, and the present invention takes the quick-change tray 1 as an example for description.

[0035] The hook grabbing block 9 is fixed on one side of the mounting b...

Abstract

The invention provides a grabbing mechanism without a driving source and a grabbing method. A workpiece is locked by self-locking based on self gravity and friction force, and therefore energy consumption is avoided. The mechanism comprises a hooking claw grabbing block assembly and a hooking claw seat assembly; the hooking claw grabbing block assembly comprises a hooking claw grabbing block and amounting plate which is longitudinally arranged, and the hooking claw grabbing block is fixed on one side of the mounting plate; the side surface of the hooking claw grabbing block comprises an arc conical surface C used for being grabbed, an axis of the arc conical surface C is arranged in the longitudinal direction, and the conical bottom is downward; the hooking claw seat assembly comprises ahooking claw seat and two hooking claw positioning blocks; a hooking claw groove matched with the hooking claw grabbing block is formed in the upper surface of the hooking claw seat, and the hooking claw groove is provided with an arc conical surface D matched with the arc conical surface C; an opening is formed in one side surface of the hooking claw groove so as to enable the hooking claw grabbing block to enter the hooking claw groove when the hooking claw groove moves upwards; and the two hooking claw positioning blocks are mounted on the two sides of the hooking claw seat, and the hookingclaw positioning blocks position the mounting plate in a contact mode during grabbing.

Description

Technical field [0001] The invention belongs to the technical field of manipulators, and specifically relates to a grabbing mechanism and a grabbing method without a driving source. Background technique [0002] There are many types of existing automated grippers, some are dedicated and some are universal. Most of them are the basic form of positioning and locking. The power source for locking has two types: compressed air drive and electric drive. Pneumatic locking is realized. The structure is compact, and it can be realized as long as there is a compressed air source. The electric drive mode is large in size and high in cost, but it has the advantages of high precision, adjustable locking force, and fine control. Unless otherwise specified, the compressed gas in the text refers to industrial compressed air with a pressure of about 0.6MPa. [0003] The two types of positioning and locking are pneumatic gripper and robot end tool quick change. The gripper is a chuck pull nail dev...
