Brief description of the drawings
The following drawings is only intended to, in doing the utility model schematic illustration and explanation, not limit model of the present utility model
Enclose.Wherein,
The dimensional structure diagram of the gripping tool according to a specific embodiment of the present utility model is shown in Fig. 1；
The cross section structure diagram of gripping tool described in Fig. 1 is shown in Fig. 2；
The end structure enlarged diagram of gripping tool shown in Fig. 2 that Fig. 3 is shown.
Embodiment
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, now control is illustrated
Embodiment of the present utility model.Wherein, identical part uses identical label.
As Figure 1-3, wherein the gripping tool according to a specific embodiment of the present utility model is shown respectively
Dimensional structure diagram, cross section structure diagram and end structure enlarged diagram.Illustrate crawl work of the present utility model
Tool is available for crawl part 1 in automated assembling equipment, wherein diagram part 1 is the middle copper screw with through hole 11, when
So, it will be appreciated by those skilled in the art that the part 1 can also be any one similar part, such as nut, nut, spiral shell
Bolt, pad, jump ring etc..Obviously, the utility model illustrates the side that this part 1 with through hole 11 can not be adsorbed using air-flow
Formula is captured, and copper screw can not also be drawn by magnetic force.Certainly, gripping tool 1 of the present utility model is not yet
It is only limitted to be used to capture with holes, non-ferromagnetic components, it can also capture other solid, non-porous, ferromagnetic parts.
It is a kind of gripping tool of similar claw structure to illustrate gripping tool of the present utility model, but with prior art not
With gripping tool of the present utility model does not have any turning joint, generally only includes a cylinder with centre bore 21
The crawl bar 2 of shape, the grasping end of crawl bar 2, which is provided between multiple joint-cuttings 3, adjacent joint-cutting 3, is formed with a grabbing claw 4, grabs
The lead-in chamfered for taking the end of pawl 4 to be provided with the buckle step 41 for blocking part 1 and guide part 1 to squeeze into buckle step 41
42。
When gripping tool of the present utility model is used, the crawl alignment element 1 of bar 2 is firmly stabbed, part 1, which is squeezed, press against
Slided along lead-in chamfered 42, grabbing claw 4 is strutted, then part 1 is squeezed into buckle step 41 and is stuck, then just can be with
The motion of crawl bar 2 is crawled required installation site.
Further, the gripping tool can also be included part 1 in a centre bore 21 that bar 2 is captured by inserting
From the end of grabbing claw 4 disclose the action bars (not shown) from buckle step 41, i.e. part 1 be crawled installation site it
Afterwards, it is possible to use part 1 is disclosed by the action bars insertion centre bore 21 not shown in figure from crawl bar 2.The action bars
It can be simple solid hopkinson bar, can also be designed to part 1 can be disclosed and suitable for the structure of subsequent installation as needed.
Crawl bar 2 of the present utility model can be made up of plastics or metal with certain rigidity and elasticity, for example may be used
To be made of stainless steel.Once, grabbing claw 4 can be all softened once crawl part 1, therefore grabbing claw 4 needs to have one every time
Fixed elasticity, but be also required to ensure possess certain chucking power, it is to avoid part comes off when crawl is mobile.Grabbing claw 4
Elasticity and chucking power size are related to the quantity of joint-cutting 3, and the quantity of joint-cutting 3 is equal to the quantity of grabbing claw 4, and minimum is 2, now
The elasticity of grabbing claw 4 is minimum, and chucking power is maximum, but grabbing claw 4 is easily broken off, and the abrasion to part 1 is maximum.Of joint-cutting 3
Number is more, and the elasticity of grabbing claw 4 is bigger, but chucking power can diminish, and part easily comes off, and the number of joint-cutting is up to 6, excellent
Elect as shown in Figure 14 as, preferably service life and reliability can be kept.
In addition, grabbing claw 4 is frequently back and forth strutted, easily form stress concentration in the bottom of joint-cutting and be broken, in order to keep away
Exempt from this problem, in a preferred embodiment, the bottom of joint-cutting 3 is provided with and communicated with stress of the diameter more than the width of joint-cutting 3
Release aperture 5, as shown in Figure 1-2, wherein it is preferred that 1.2-1.6 times of the width of a diameter of joint-cutting 3 of the stress relief hole 5.
Further, in order to improve the reliability of crawl, it is to avoid part comes off, as shown in Figure 3, it is preferable that buckle step
41 have a containing angle α for being not more than 10 degree, so that the angle of buckle step 41 and the delivery position of lead-in chamfered 42
Diminish, add the frictional force between part 1.
In a further advantageous embodiment, lead-in chamfered 42 preferably has the outer enlarging-angle β of a 15-45 degree, so that part 1
It is more smoothly when squeezing into, and extruding guiding dynamics is moderate, it is to avoid part is scratched.
In summary, gripping tool of the present utility model does not have any turning joint, in generally only having including one
The crawl bar of the tubular in heart hole, simple in construction without complicated movable device, with low cost, reliability is high, it is adaptable to it is various from
Dynamicization assembly equipment, be particularly suitable for use in holes, non-ferromagnetic components the crawls that can not be drawn using air-flow absorption and magnetic force.
Although it will be appreciated by those skilled in the art that the utility model is described in the way of multiple embodiments
, but not each embodiment is only comprising an independent technical scheme.So narration is just for the sake of clear in specification
For the sake of, the skilled in the art should refer to the specification as a whole is understood, and by skill involved in each embodiment
Art scheme, which is regarded as, can be mutually combined into the mode of not be the same as Example to understand protection domain of the present utility model.
The schematical embodiment of the utility model is the foregoing is only, model of the present utility model is not limited to
