Abstract
The utility model discloses a dismounting device of cutting nut, including the connecting rod, the one end fixed connection handle of connecting rod, the tool bit is connected to the other end of connecting rod, swing joint stop mechanism on the connecting rod for the chucking nut. Through the design of the telescopic section of the blocking mechanism, the nut can be well fixed and disassembled, and the dangerous accidents caused by electric sparks generated by using an electric tool are avoided. Compared with the traditional inner hexagonal sleeve type combined tool, the problems that small inner six-wheel nuts are easy to fall off when being placed into a large sleeve type tool, inconvenient to carry and inflexible to use are solved. Simple structure, convenient to carry, use flexibility and effectively improved the operating efficiency.
Description
Technical Field
The utility model belongs to the technical field of extracting tool, concretely relates to dismounting device of cutting nut.
Background
Along with the increase of railway transportation volume, the requirements on equipment maintenance quality and maintenance efficiency are higher and higher. When the ZD6-D type switch machine is used for maintenance work to replace the internal extruding and cutting pin nut, the disassembly by adopting the combined sleeve tool is very inconvenient, and the six-edge small nut in the large sleeve is easy to fall off and fall into the rack block. The existing disassembling tool for extruding and cutting the nut is an inner hexagonal sleeve type combined tool, a small inner hexagonal nut needs to be placed into a large sleeve for disassembling during operation, a small inner six-wheel nut is easily dropped off when being placed into the large sleeve tool, and the disassembling tool is inconvenient to carry, inflexible to use and capable of affecting the operation efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dismounting device of cutting nut has solved the interior hexagonal telescope-feed combination tool that uses when current railway goat overhauls, and six rounds of nuts drop easily in putting into big sleeve tool in little, carry inconveniently, use inflexible problem.
The utility model provides a technical scheme is, a dismounting device of cutting nut, including the connecting rod, the one end fixed connection handle of connecting rod, the tool bit is connected to the other end of connecting rod, swing joint stop mechanism on the connecting rod for the chucking nut.
The utility model discloses an other characteristics still lie in, through the flexible section of threaded connection between connecting rod and the tool bit.
The inner wall of the connecting rod is provided with a thread section used for moving the telescopic section.
The end part of the telescopic section is fixedly connected with a cutter head.
The telescopic section drives the cutter head through a thread jacking structure.
The stopping mechanism comprises a fixed frame fixed on the connecting rod, two ends of the fixed frame are respectively hinged with a fixed clamp, and a spring is fixedly connected between the middle part of each fixed clamp and the fixed frame.
The fixing frame is connected with the fixing clip through a pin.
The fixing clip is in a semicircular shape, a crescent shape or an angular shape.
One end of the fixing clip far away from the fixing frame is provided with a clamping hook for fixing a nut.
The tool bit is a plain end tool bit.
The beneficial effects of the utility model are that, a dismounting device of cutting nut has solved the interior hexagonal telescope-feed combination tool that uses when current railway goat overhauls, and six rounds of nuts drop easily in putting into big sleeve tool in little, carry inconveniently, use inflexible problem. Through the design of the telescopic section of the blocking mechanism, the nut can be well fixed and disassembled, and the use is convenient only through manual operation.
Drawings
Fig. 1 is a schematic structural view of a dismounting device for a cutting nut of the present invention.
In the figure, 1, a handle, 2, a fixing frame, 3, a cutter head, 4, a connecting rod, 5, a fixing clamp and 6, a spring.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a dismounting device of cutting nut, as shown in fig. 1, including connecting rod 4, the one end fixed connection handle 1 of connecting rod 4, tool bit 3 is connected to the other end of connecting rod 4, swing joint stop mechanism on connecting rod 4 for the chucking nut.
The connecting rod 4 is connected with the cutter head 3 through a thread to form a telescopic section.
The inner wall of the connecting rod 4 is provided with a thread section for moving the telescopic section.
The end part of the telescopic section is fixedly connected with a cutter head 3.
The telescopic section drives the cutter head 3 through a thread jacking structure.
The stopping mechanism comprises a fixed frame 2 fixed on a connecting rod 4, two ends of the fixed frame 2 are respectively hinged with a fixed clamp 5, and a spring 6 is fixedly connected between the middle part of each fixed clamp 5 and the fixed frame 2.
The fixing frame 2 is connected with the fixing clip 5 through a pin.
The fixing clip 5 is in a semicircular shape, a crescent shape or an angular shape.
One end of the fixing clip 5 far away from the fixing frame 2 is provided with a clamping hook for fixing a nut.
The cutter head 3 is a plain cutter head.
The utility model discloses an all parts can all general calculation adopt on the railway abandonment steel to carry out appropriate processing welding and obtain among the dismounting device of cutting nut, with low costs to the used repeatedly of abandonment steel on the railway has been realized.
The utility model discloses a dismounting device of cutting nut is when dismantling the dead nut of rusty, at first according to the hinge degree of connection between nut size adjustment fixing clip 5 and the fixed frame 2, because the existence of spring 6 for the trip card of 5 tip of fixing clip is fixed at the relative both sides wall of nut, then, through hand handle 1, rotates handle 1, and the flexible section pushes up tightly under the effect of the 4 inner wall screw thread sections of connecting rod, drives tool bit 3 and dismantles rusty nut. Because at the dismantlement in-process, external force is applyed through handle 1, rotates handle 1, thereby moves chucking nut at screw thread section effect expansion segment to because the fixed action of fixing clip, can guarantee that the nut atress is even at the dismantlement in-process, still can avoid the deformation of nut wantonly in addition. After the nut is disassembled, the handle 1 is rotated again to drive the telescopic section to move upwards, and the fixing clamp 5 is loosened under the action of the spring 6 and moved out of the disassembling device.
The utility model discloses a dismounting device of cutting nut need not only in the use only manually operation can, when guaranteeing to dismantle the nut, avoided using electric tool to produce the electric spark and caused the dangerous accident. Compared with the traditional inner hexagonal sleeve type combined tool, the problems that small inner six-wheel nuts are easy to fall off when being placed into a large sleeve type tool, inconvenient to carry and inflexible to use are solved. Simple structure, convenient to carry, use flexibility and effectively improved the operating efficiency.
