Abstract
The utility model discloses the telescopic screw rod clamping devices for tearing screw machine open, tear the billy gate in front of screw machine and/or rear open including being arranged in, the billy gate tears the fuselage of screw machine open by telescopic rod connection, and the auxiliary holding device for clamping screw rod is equipped on the billy gate.The utility model provides a kind of telescopic screw rod clamping device for tearing screw machine open, can be used for being auxiliarily fixed longer screw rod, while can carry out feeding and the material returned, makes to tear screw rod function open and more easily be processed.
Description
Technical field
It is especially a kind of for tearing the clamping of the telescopic screw rod on screw machine open the utility model relates to machinery equipment field
Mechanism.
Background technique
Screw extruder is common equipment in plastic processes, the screw rod on existing screw extruder, most of
It is made of mandrel and the threaded components being socketed on mandrel, threaded components can be replaced according to needs of production.But
For plastic processing quotient, the threaded components replaced on screw rod in process of production are a time-consuming and laborious things.
Under normal conditions, replacement threaded components needs first original threaded components are disassembled from screw rod, then into
Row replacement, assembling.But since screw rod often bears the effect of high temperature and high pressure in machine barrel, so that liquid plastic is squeezed into
To between threaded components and mandrel, and carbide is generated herein, threaded components is caused firmly to be bonded into one with screw mandrel,
Sometimes or even also cause to be squeezed and deformed.Therefore, threaded components are disassembled, it is by no means easy.For a long time, people are dismantling
When screw rod generally by the way of beaing by hand, this one hammer into shape unidirectionally beat mode often threaded block is caused it is very big
Impact, often makes threaded components be crashed to pieces, cause it is various scrap phenomenon, increase cost of equipment maintenance；It strikes by hand simultaneously
The mode beaten requires worker to carry out labour high-intensitive for a long time, and inefficiency, very inconvenient.
Applicant by studying intensively, have developed it is a kind of can quickly and easily dismantling screw machine, which passes through the
One clamping device standing screw, the second gripping apparatus grips threaded components, and push the second clamping device to make using propulsive mechanism
It is mobile relative to the first clamping device, and threaded components is made slowly to deviate from screw mandrel.The equipment is usually used in processing longer screw rod,
And rely only on the first clamping device and the second clamping device is difficult to be completely fixed screw rod, therefore, it is necessary to be provided with to be auxiliarily fixed
Mechanism.
Utility model content
In order to improve the applicability for tearing screw machine open, long bolt can be easily processed, the purpose of this utility model is that
It provides a kind of for tearing the telescopic screw rod clamping device on screw machine open, screw rod is auxiliarily fixed.
The technical scheme adopted by the utility model is that：
The telescopic screw rod clamping device for tearing screw machine open, tears the activity in front of screw machine and/or rear open including being arranged in
Trolley, the billy gate are torn open the fuselage of screw machine by telescopic rod connection, are equipped on the billy gate for clamping spiral shell
The auxiliary holding device of bar.
As a further improvement of the above technical scheme, the auxiliary holding device includes fixed bracket, the fixed branch
The V-type collet for clamping screw rod and the driving device of driving V-shaped collet movement are provided on frame.
As a further improvement of the above technical scheme, the V-type collet includes the fixture block there are two V-type.
As a further improvement of the above technical scheme, the driving device drives two fixture blocks by rack gearing
Relative motion.
As a further improvement of the above technical scheme, the driving device is oil cylinder or cylinder.
As a further improvement of the above technical scheme, the billy gate bottom is provided with idler wheel.
The utility model has the beneficial effects that：
The utility model provides a kind of telescopic screw rod clamping device for tearing screw machine open, can be used for being auxiliarily fixed longer
Screw rod, while feeding and the material returned can be carried out, make to tear screw rod function open and more easily be processed.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic perspective view for tearing screw machine open.
Fig. 2 is the schematic perspective view of auxiliary holding device.
Specific embodiment
With reference to Fig. 1, the utility model provides one kind and tears screw machine, including fuselage 1 open, is provided with sliding rail, sliding rail on fuselage 1
On be installed with the first clamping device 2 and the second clamping device 3, first clamping device 2 includes the concentric folder of hydraulic-driven
Pawl is used for standing screw, the mold for clamping threaded components is installed on the second clamping device 3, when 2 He of the first clamping device
After second clamping device 3 clamps target respectively, the second clamping device is pushed to make it with respect to the first clamping device using propulsive mechanism
It is mobile, so that threaded components is slowly deviate from screw mandrel.In the present embodiment, 1 front and back of fuselage is provided with billy gate
5, billy gate 5 connects fuselage 1 by telescopic rod 51, and 5 bottom of billy gate is provided with idler wheel 52, and top is equipped with for clamping
The auxiliary holding device 4 of screw rod, the effect of auxiliary holding device 4 are that longer screw end is fixed, and pass through additional lock
It holds device 4 and clamps screw rod, front and back pushes billy gate 5, can play the effect of feeding and the material returned；It simultaneously can be according to the difference of screw rod
The initial position of length adjustment billy gate 5, is preferably auxiliarily fixed.
Referring to Fig. 2, the auxiliary holding device 4 includes that fixed bracket 17, V-type collet 18 and driving V-shaped collet 18 are dynamic
The driving device 19 of work, it is preferred that the driving device 19 is oil cylinder or cylinder.The V-type collet 18 includes that there are two V-types
Fixture block, driving device 19 by rack gearing 20 drive two fixture block relative motions, to clamp screw rod.
The above specific structure is that the preferred embodiment to the utility model has carried out specific description, but is not intended to limit
The embodiments of the present invention and protection scope, those skilled in the art are without prejudice to before the spirit of the present invention
Various equivalent variations can also be made perhaps these equivalent deformations or replacement of replacement are all contained in the application right by putting
It is required that in limited range.
