Applicant is 20121050724.5 in the patent No. of applying for before, name is called in the Chinese patent of " articulated robot refers to ", disclose a kind of manipulator, it comprises the assembly 1 that is strained and fixed be connected successively, connectors 2 and fixed support 3, be strained and fixed assembly 1, connectors 2, be connected with the steel wire 7 be located in spring 6 by spring 6 between fixed support 3, articulated robot refers to be fixedly connected on manipulator fixed head 8 by the assembly 1 that is strained and fixed, mechanical finger can realize the same multidirectional activity adjustment of similar people's swivel of hand by connector 2.
When carrying out product and capturing, often need multiple mechanical finger to carry out work simultaneously, therefore we investigated and a kind ofly multiple mechanical finger can be combined and installed together, to realize the mechanical palm that multiple product captures simultaneously, mechanical finger is assembled into our discovery after on palm, direction of rotation adjustment can only be realized in use, and can not regulate in the distance of product, like this when mechanical finger touching is less than product, can not only adjust the position of mechanical finger, therefore regulate very inconvenient, and complex operation.
Summary of the invention
The object of the invention is to the defect overcoming prior art, provide a kind of chute to point, to realize mechanical finger to be assembled into manipulator palm, and the distance achieving mechanical finger distance product is adjustable.
For achieving the above object, the present invention proposes following technical scheme: a kind of chute finger, comprise palm connecting portion, be arranged on the coupling assembling on palm connecting portion, and finger mounted chute, described coupling assembling comprises fixed screw, hold-down nut and buffer spring, the screw rod that described fixed screw comprises blind nut and extended outward by blind nut, described screw rod is through described palm connecting portion, described hold-down nut knob is in the threaded one end of described screw rod, described buffer spring is enclosed within described screw rod, and be compressed under the effect of described hold-down nut in the perforation of described palm connecting portion.
Preferably, the end face of described finger mounted chute both sides is provided with the slide rail slided for mechanical finger.
Preferably, an end face of the end face homonymy of described palm connecting portion and screw is provided with multiple directions and regulates projection.
Preferably, sealing ring is provided with between described buffer spring and hold-down nut.
Preferably, described hold-down nut is wing nut.
Compared with prior art, the novel structure of chute of the present invention finger, simple, processing cost is low, and the distance achieved between mechanical finger and product is adjustable, is convenient to mechanical finger to the movement of product and crawl.

Detailed description of the invention
Below in conjunction with accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme of the embodiment of the present invention.
Shown in composition graphs 1 ~ Fig. 6, disclosed a kind of chute finger, for mechanical finger (not shown) is installed to fixing palm, shown in composition graphs 1 and Fig. 2, fixing palm comprises palm body 1 and to be stretched out the multiple finger connecting portions 2 formed out by the edge of palm body 1, the shape of the similar people's palm of shape of palm body 1, is roughly rectangle.Palm body 1 have 5 finger connecting portions 2, finger connecting portion 2 is for installing mechanical finger by a chute finger 3, the finger that 5 connecting portions 2 are installed is equivalent to the thumb of staff, forefinger, middle finger, the third finger and little finger respectively, after installing mechanical finger, 5 mechanical fingers can be realized to the crawl of product simultaneously.
The surface of palm body 1 is also offered the installing hole 11 of multiple strip, arranging of installing hole 11 being on the one hand whole weight in order to alleviate palm, reducing rapidoprint, is also load onto other instruments for adding on the other hand.Also adsorbable upper gas circuit rectifying block (not shown) on palm body 1, divides the multiple mechanical finger of supply to carry out work after the source of the gas rectification needed for mechanical finger drives by gas circuit rectifying block again.
Each finger connecting portion 2 is in the circular configuration with a breach, and this breach is used for the installation gap 21 of chute finger mounted.And a wherein end face (hereinafter referred to front) of each finger connecting portion 2 is provided with multiple directions adjusting grooves 22, direction adjusting grooves 22 circumference is distributed in installation gap 21 around.The other end (hereinafter referred to reverse side) of each finger connecting portion 2 is provided with a stopper slot caved inward 23, and the bottom surface of stopper slot 23 is plane, and its side is 4 trapezoidal faces.
The design of direction adjusting grooves 22 and stopper slot 23 is all that the corresponding construction in order to point on 3 with chute is spacing to engaging, to realize being fastenedly connected between chute finger 3 and finger connecting portion 2.Particularly, shown in composition graphs 3 ~ Fig. 5, chute finger 3 comprises palm connecting portion 31 and finger mounted chute 32, chute finger 3 is fixedly connected with finger connecting portion 2 by a coupling assembling 4 by palm connecting portion 31, the one side that palm connecting portion 31 and finger connecting portion 2 fit is provided with the direction of matching with direction adjusting grooves 22 and regulates protruding 311, the setting of groove and projection is adjustable for the direction realizing chute finger 3, when specifically regulating, projection is removed in the groove matched, again engage in the groove being embedded into needs again, so just, the direction of rotation achieving mechanical finger is adjustable.
Coupling assembling 4 comprises fixed screw 41, hold-down nut 42 and buffer spring 43, shown in composition graphs 3 and Fig. 6, the screw rod 412 that fixed screw 41 comprises blind nut 411 and stretched out by wherein one end facing epitaxy of blind nut 411, the lower end of screw rod 412 is provided with screw thread, screw rod 412 passes front from the reverse side of finger connecting portion 2, the side that blind nut 411 and the reverse side of finger connecting portion 2 fit is provided with the spacing preiection 4111 matched with stopper slot 23, the shape of spacing preiection 4111 and the shape of stopper slot 23 similar, bottom surface is plane, side is 4 trapezoidal faces, the design of spacing preiection 4111 and stopper slot 23 is for fixing blind nut 411 when locking nut, prevent blind nut 411 from and then rotating.
Hold-down nut 42 is sleeved on the threaded one end of screw rod 412, and when locking chute finger connecting portion 2, hold-down nut 42 carries out knob to the direction of finger connecting portion 2, and hold-down nut 42 can select wing nut.Buffer spring 43 between hold-down nut 42 and blind nut 411, hold-down nut 42 for be contracted in during tightening state palm connecting portion 31 screw perforation in.Screw rod 412 is also set with one or more sealing ring 51 between buffer spring 43 and hold-down nut 42, to improve the degree of blocking of hold-down nut 42.
Finger mounted chute 32 refers to for installation manipulator, the end face of its both sides is provided with the slide rail 321 slided for mechanical finger, and mechanical finger can move forward and backward along slide rail 321, realizes the adjustment of multiple directions, position flexibly.
