Description
Technical field
The present invention relates to injection molding technology fields, and in particular to the ancillary equipment of injection molding.
Background technique
Existing fixture, such as injection molding mechanical arm fixture, the fixture is mounted on injection molding machine, by pushing the gas on fixture
Cylinder rod controls the space size of crawl, that is, in the case where cylinder rod motion amplitude is certain, product ruler that fixture is capable of clamping
Very little is fixed.
Summary of the invention
Technical problem solved by the invention: fixture is made automatically to clamp the product of various sizes.
In order to solve the above technical problems, the invention provides the following technical scheme: one kind automatically grabs fixture, including clamping fixture seat
With the clamp assembly being mounted on the clamping fixture seat, the clamp assembly includes bone grabbing base, is mounted on grabbing on the bone grabbing base
Bone grabs bone driving assembly and grabs reduction component, and the bone grabbing base opens up air cavity and reseting cavity, grabs bone driving assembly and the gas
Chamber cooperation, supplies to air cavity；Grabbing reduction component has elasticity, cooperates with the reseting cavity；The main body for grabbing bone is located at bone grabbing base
Outside, grab and be hinged in the middle part of bone on the bone grabbing base, the tail portion for grabbing bone is located in bone grabbing base and is located at air cavity and reseting cavity
Between.
According to the above technical scheme, bone driving assembly is grabbed to gas interacvity air-filling, and the pressure of air cavity increases, and driving grabs bone around it
It is swung with the articulated shaft of bone grabbing base, it is in the open state to grab bone.Meanwhile grabbing bone effect and grabbing reduction component, grab reduction component
Gather elastic potential energy.When needing to grab product, the pumping of bone driving assembly is grabbed, the elastic potential energy for grabbing reduction component is released,
In the case where grabbing bone driving assembly and grabbing the collective effect of reduction component, bone backswing is grabbed, it can be clamped in for product by grabbing bone main body
Between clamping fixture seat.
The present invention uses gas and elastic component to directly drive and grabs bone and swing with product clamping, due to gas and elastic component can
Compressibility, it is not fixed for grabbing the amplitude of bone swing, in this way, grab bone can the automatically different product of clamping dimension, compared to
In the prior art by cylinder rod move product clamping fixture, fixture of the present invention it is applied widely.

Specific embodiment
Such as Fig. 1, one kind automatically grabbing fixture, including bottom plate 40, middle plate 30 and clamp assembly 10.
Such as Fig. 2, the middle plate 30 is mounted on bottom plate 40, the quantity of middle plate be it is several, all middle plates are located at same
In one plane, plane where all middle plates is parallel to the bottom plate, as a preference, the quantity of middle plate is two, point
It is not mounted on the left and right ends of bottom plate.
The middle plate 30 is mounted on bottom plate 40 by link block 32, and link block is mounted on bottom plate by the first screw 33
On, link block connects middle plate by the second screw 34.
The middle plate 30 and the bottom plate 40 constitute clamping fixture seat.
The middle plate 30 is equipped with the baffle 31 that is limited to product, the quantity of baffle be it is several, distribution is in middle level
The edge of plate.Any baffle is L-shaped, and any baffle is mounted on middle plate by third screw 35.
Such as Fig. 1, several clamp assemblies 10 are installed on each middle plate 30, as a preference, pacifying on each middle plate
Equipped with eight clamp assemblies, eight clamp assemblies are distributed in around middle plate in an annular manner.
Such as Fig. 3, the clamp assembly 10 includes bone grabbing base 11, is mounted on grabbing bone 12, grabbing bone driving on the bone grabbing base
Component and grab reduction component.
The bone grabbing base 11 is mounted on middle plate 30 by jam plate 112, pressing plate 113, the 4th screw 114, specifically, lock
Plate is located at the top of bone grabbing base, and pressing plate 113 is located at the lower section of bone grabbing base, and the 4th screw from bottom to top passes through pressing plate and jam plate
Afterwards, it then is screwed at the bottom margin of middle plate.
The bone grabbing base 11 opens up air cavity and reseting cavity, opens up between air cavity and reseting cavity and grabs bone installation cavity, grabs bone installation
Chamber is connected to air cavity and reseting cavity.Wherein, bone installation cavity top opening is grabbed.The main body for grabbing bone is located at the outside of bone grabbing base, grabs bone
Middle part be hinged on the bone grabbing base by articulated shaft 121, the articulated shaft be located at it is described grab in bone installation cavity, grab the tail of bone
Portion, which is located at, grabs in bone installation cavity and between air cavity and reseting cavity.Wherein, the articulated shaft 121 is screwed on bone grabbing base 11
Lock shaft screw 122 lock.
The bone driving assembly of grabbing includes cylinder 131 and tracheae 132, and the escape pipe 133 of cylinder cooperates in the air cavity,
For sealing cooperation, the head end of tracheae is connect with cylinder, and the tail end of tracheae is connect with feeder.One steam line of feeder
20 are connect by quick coupling 21 with the tracheae 132 of eight clamp assemblies, and specifically, the tracheae 132 of a clamp assembly passes through
One quick coupling 21 is connect with the steam line 20.
The reduction component of grabbing includes wire spring 141, motion bar 142, spring lock block 143；Motion bar is equipped with limit
