Abstract
The utility model relates to a robot grabbing arm, in particular to a robot grabbing arm with adjustable width in a large adjustment range, which comprises fixed arm and a movable arm. The fixed arm and the movable arm are respectively formed by a grabbing portion and a fastening adjusting portion which are connected in an L shape. The grabbing portion is in a casing type structure, and a drive device is respectively mounted on the fixed arm and the movable arm. The robot grabbing arm is characterized in that the fastening adjusting portion of the movable arm is in a square-tubular structure, three or more than three threaded holes equidistantly distributed are arranged on the top portion of the movable arm, the fastening adjusting portion of the fixed arm is in a square-groove structure, a groove opening faces the grabbing portion of the grabbing arm, and matched adjusting holes with same spacing and same amount with the threaded holes are disposed on the top portion of the fixed arm. The structure is capable of realizing substantial adjustment of grabbing width of the grabbing arm, and maximum grabbing width can reach three times or more than three times of minimum grabbing width, thereby greatly increasing compatibility of the grabbing arm.
Description
One, technical field
The utility model designs the gripping arm of a kind of robot, the broad-adjustable robot gripping arm that especially a kind of adjusting range is big.
Two, background technology
It is to adopt spraying technology to produce that a kind of polyurethane product is arranged at present, in spraying process, need grasp material by gripping arm by robot, and the control goods are according to certain orbiting motion, to realize the spraying homogeneous and controllable of material surface; The existing robots gripping arm is because width adjustment is to adopt tube-in-tube structure, so the adjusting range of width is more limited, minimum widith is the length of cover, maximum grasp width is all less than the twice of minimum grasp width, and in actual production, the change in size of product is very big, the size difference of big miscellaneous goods can reach twice even more, in this case, and can not all products of compatibility once the cover gripping arm, need to make the gripping arm of many covers, could obtain wideer compatible scope, and will frequently change gripping arm, operate loaded down with trivial details according to the size of different product, efficient is low, the cost height.
Three, summary of the invention
The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, provides that a kind of width adjusting scope is wide, the compatible wide ranges of product size, broad-adjustable robot gripping arm simple to operate.
For achieving the above object, the utility model is achieved in that the gripping arm of a kind of broad-adjustable robot, comprise respectively by be that gripping portion that the L type connects and fastening adjustment partly constitute fixed arm and lever arm, gripping portion is a telescoping structure, the gap bearing is housed between inner core and urceolus, on the inner core of fixed arm and lever arm gripping portion, be provided with the extracting washer that cooperatively interacts, drive unit is housed respectively on fixed arm and the lever arm, drive unit all is to drive in the shell and the air motor that is connected with the gripping portion inner core constitutes by placing, driving shell fixedlys connected with the urceolus of gripping portion with fastening adjustment part separately respectively, its special character is, the fastening adjustment of lever arm partly is the square tube type structure, and its top is provided with 3 screwed holes that distribute with equal intervals, the fastening adjustment of fixed arm partly is a square groove formula structure, the notch of square groove is towards the gripping portion of gripping arm, its top be provided with screwed hole with the equally spaced fit adjustment of quantity hole, the fastening adjustment of lever arm partly is assemblied in the square groove of fastening adjustment part of fixed arm and by the screw that is installed in corresponding screwed hole and the fit adjustment hole and is anchored on one.
The good effect that compared with the prior art the utility model has is, can realize the adjustment significantly of gripping arm grasp width, maximum grasp width can reach more than 3 times of minimum grasp width, improved the compatibility of gripping arm greatly to product size, reduce the troublesome operation of frequent replacing gripping arm, improved operating efficiency effectively.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is minimum grasp width schematic diagram.
Five, the specific embodiment
For better understanding the utility model, it is described in further detail below in conjunction with drawings and Examples.As Fig. 1, shown in Figure 2, broad-adjustable robot described in the utility model gripping arm mainly is by the fixed arm that is L type structure and lives and to decide arm and cooperatively interact and constitute, fixed arm comprises gripping portion 201 and fastening adjustment part 203, the two connects into the L type by drive unit 202, lever arm also connects into the L type by gripping portion 206 and fastening adjustment part 204 by drive unit 205, gripping portion 201,206 all is to adopt telescoping structure, the gap bearing is housed between inner core and urceolus, on the inner core of fixed arm and lever arm gripping portion, is provided with the extracting washer that cooperatively interacts; Drive unit 202,205 all is by placing the air motor that drives in the shell to constitute, the air motor of drive unit 202 is connected with the inner core of gripping portion 201, drives shell and then the urceolus of fastening adjustment part 203 and gripping portion 201 is fixedly connected into the L type; The air motor of drive unit 205 is connected with the inner core of gripping portion 206, drives shell and then the urceolus of fastening adjustment part 204 and gripping portion 206 is fixedly connected into the L type.The fastening adjustment part 203 of lever arm is the square tube type structure, and its top is provided with 3 screwed holes that distribute with equal intervals, the fastening adjustment part 204 of fixed arm is a square groove formula structure, the notch of square groove is towards the gripping portion of gripping arm, its top be provided with screwed hole with the equally spaced fit adjustment of quantity hole, the fastening adjustment part 203 of lever arm is inserted in the square groove of fastening adjustment part 204 of fixed arm and is anchored on one by being installed in screw in corresponding screwed hole and the fit adjustment hole.
During use, the width adjustment of gripping arm is by adjusting the degree of depth that lever arm inserts fixed arm, selecting suitable screwed hole and adjustment hole to carry out stationary positioned and get final product, and is convenient to operation, realized the wide compatibility of product size.
