Description
Technical Field
The utility model belongs to the technical field of mechanical equipment and specifically relates to a screw rod auxiliary fixing structure for tearing open on screw rod machine.
Background
The screw extruder is the equipment commonly used in the plastics processing procedure, and the screw rod on the screw extruder of current, most are by the dabber and cup joint the screw thread subassembly on the dabber and constitute, and the screw thread subassembly can be changed according to actual production needs. However, it is time consuming and laborious for the plastics processor to replace the screw assembly on the screw during the production process.
In general, replacing the screw assembly requires disassembling the original screw assembly from the screw rod, and then replacing and assembling the screw assembly. However, since the screw is often subjected to high temperatures and pressures in the barrel, liquid plastic is squeezed between the screw thread component and the mandrel, and carbides are generated therein, resulting in the screw thread component and the screw mandrel being firmly bonded together, sometimes even causing extrusion deformation. Therefore, it is not easy to disassemble the screw assembly. For a long time, people generally adopt a manual beating mode when disassembling the screw rod, the one-hammer one-way beating mode often causes great impact on the thread block, the thread component is often broken, various scrapping phenomena are caused, and the equipment maintenance cost is increased; meanwhile, the manual beating mode requires a worker to perform long-time high-intensity labor, and is low in efficiency and very inconvenient.
The applicant develops a machine capable of conveniently and quickly disassembling the screw through elaborate research, the machine fixes the screw through the first clamping device, the second clamping device clamps the threaded component, and the pushing mechanism is adopted to push the second clamping device to move relative to the first clamping device, so that the threaded component is slowly separated from the screw mandrel. This device is often used for processing longer screws, and it is difficult to completely fix the screws by means of only the first and second clamping means, and therefore, it is necessary to provide a mechanism for assisting the fixation.
SUMMERY OF THE UTILITY MODEL
In order to improve the applicability of tearing screw rod machine open, make its processing long screw rod that can be convenient, the utility model aims to provide a screw rod auxiliary fixing structure for tearing open on the screw rod machine can assist fixedly to the screw rod.
The utility model adopts the technical proposal that:
the screw auxiliary fixing structure of the screw disassembling machine comprises a fixing support movably arranged on the machine body of the screw disassembling machine, wherein a V-shaped chuck used for clamping a screw is arranged on the fixing support, and a driving device used for driving the V-shaped chuck to act is arranged on the fixing support.
As a further improvement of the technical scheme, the V-shaped chuck comprises two V-shaped clamping blocks.
As a further improvement of the technical scheme, the driving device drives the two clamping blocks to move relatively through the rack transmission device.
As a further improvement of the technical scheme, the driving device is an oil cylinder or an air cylinder.
As a further improvement of the technical scheme, the fixed support is slidably mounted on the screw disassembling machine body through a pulley.
As a further improvement of the technical scheme, the fixing bracket is provided with a screw rod assembly for adjusting the position of the fixing bracket.
As a further improvement of the technical scheme, a protective cover is arranged on the fixed support, and a safety switch is arranged on the protective cover and connected with a starting loop of the driving device. The safety and reliability of the auxiliary fixing structure are improved through the arrangement of the protective cover.
The utility model has the advantages that:
the utility model provides a tear supplementary fixed knot of screw rod machine structure open can be used to supplementary fixed longer screw rod, makes tear screw rod machine of opening more convenient processing.

The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic perspective view of a screw-detaching machine.
Fig. 2 is a schematic perspective view of the auxiliary clamping device.
Fig. 3 is a front view of the auxiliary clamp device.
Detailed Description
Referring to fig. 1, the utility model provides a tear screw rod machine open, including fuselage 1, be provided with the slide rail on the fuselage 1, the slide rail facial make-up is equipped with first clamping device 2 and second clamping device 3, still is provided with one or more supplementary clamping device 4 on the fuselage 1. Wherein first clamping device 2 is including hydraulic drive's concentric clamping jaw for the clamping screw, and second clamping device 3 facial make-up is equipped with the mould that is used for centre gripping screw thread subassembly, and after first clamping device 2 and second clamping device 3 centre gripping target respectively, utilize advancing mechanism to promote second clamping device and make it remove relative first clamping device, make screw thread subassembly slowly deviate from the screw rod dabber, and supplementary clamping device 4's effect is fixed the terminal pay-off of longer screw rod, supplementary pay-off simultaneously.
Referring to fig. 2 and 3, the auxiliary clamping device 4 includes a fixing bracket 17, a V-shaped chuck 18, and a driving device 19 for driving the V-shaped chuck 18 to operate, and preferably, the driving device 19 is an oil cylinder or an air cylinder. The V-shaped chuck 18 comprises two V-shaped clamping blocks, and the driving device 19 drives the two clamping blocks to move relatively through the rack transmission device 20, so as to clamp the screw rod. The auxiliary clamping device 4 is used for clamping and auxiliary fixing the suspended end of the long screw, and the effect of disassembling the screw due to the suspension of the screw is avoided. In addition, the fixed support 17 is slidably mounted on the machine body 1 of the screw rod disassembling machine through a pulley, and meanwhile, a screw rod assembly used for adjusting the position of the fixed support 17 is arranged on the fixed support 17, so that the auxiliary clamping device 4 can move on the machine body 1 and is used for feeding and returning the screw rod.
Further, referring to fig. 2 and 3, a protective cover 21 is arranged on the auxiliary clamping device 4, a safety switch is arranged on the protective cover 21, the safety switch is connected with a starting loop of the driving device 19, oil can be supplied to the driving device 19 only after the protective cover 21 is completely closed, the V-shaped chuck 18 is driven to act, and safety of workers is guaranteed.
The utility model provides a screw auxiliary fixing structure of a screw disassembling machine, which can be used for auxiliary fixing of a longer screw, and can also carry out feeding and material returning, so that the screw disassembling machine can carry out processing more conveniently; meanwhile, the protective cover for safety protection is arranged on the auxiliary screw fixing structure, so that the safety and reliability of the equipment are improved.
While the above detailed description describes the preferred embodiment of the present invention, it is not intended to limit the scope of the present invention, but rather, the present invention is intended to cover by those skilled in the art all such modifications and equivalents as may be included within the spirit and scope of the present invention.
