Abstract
The utility model discloses a mandril machine device. When the mandril machine is in work state, the main workpiece is a slender mandril; and under the oversized pressure work, the two ends of the mandril are not distorted, bent and blocked by the mandril machine. The conventional solution is that the diameter of the mandril is enlarged, but because the machine space is limited, the enlarged mandril is not easy to operate, for example, the mandril can not align accurately when supports against a tiny member; moreover, by enlarging the diameter of the mandril, the problems are not solved thoroughly that the two ends of the mandril are not distorted, bent and blocked by the mandril machine when the mandril is under the oversized pressure work. In order overcome the above defects, the utility model aims to provide a device capable of preventing the mandril from being distorted, bent and blocked by the mandril machine, which is characterized in that one end of the mandril is equipped with a thread hole and a tapered spring, and the tapered spring is fixed at the end part of the mandril via a screw and a tapered sleeve.
Description
Technical field
The utility model relates to a kind of push rod machine, specifically a kind of anti-bending push rod.
Background technology
A kind of push rod machine: the push rod machine in working order in, its main position workpiece is exactly elongated push rod,, not bending, by push rod machine not stuck indeformable at the work lower push rod two ends of super large pressure.Traditional solution is to strengthen the push rod diameter, still because machine space is limited; The push rod diameter can not strengthen arbitrarily, and the push rod after strengthening is often not easy to operate, like push rod when pushing up the material of smallclothes very; Contraposition very accurately, moreover, strengthen the push rod diameter and also just mean the increase manufacturing cost; Also can increase the weight of machine simultaneously, but still can not solve push rod completely under the work of super large pressure, its push rod two ends are indeformable, not bending, not stuck by the push rod machine.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, provides a kind of and prevents push rod distortion, bending, not by the stuck device of push rod machine.
The utility model solves the technical scheme that its technical problem adopted: a kind of anti-bending push rod comprises push rod, top stem casing, volute spring.
It is characterized in that: described push rod one end is provided with screwed hole, at the push rod that is provided with screwed hole one end one volute spring is arranged.
Described volute spring is fixed on the push rod end by screw and taper sheath, need not to strengthen the push rod diameter, just can prevent the push rod bending.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is A-A cutaway view of Fig. 1.
Among the figure: 1, push rod, 2, top stem casing, 3, volute spring, 4, taper sheath, 5, screw.
The specific embodiment
Like Fig. 1, a kind of push rod machine shown in Figure 2; Comprise push rod (1), top stem casing (2); It is characterized in that: described push rod (1) one end is provided with screwed hole; At the push rod that is provided with screwed hole (1) one end one volute spring (3) is arranged, described volute spring (3) is fixed on push rod (1) end by screw (5) and taper sheath (4).Excessive when the instantaneous pressure at push rod two ends, when perhaps movement travel was transfinited, the volute spring (3) that is fixed on push rod (1) end will be compressed, and to alleviate instantaneous pressure, prevented push rod (1) bending, distortion, stuck.
The utility model is not limited to above-mentioned implementation method, and anyone should learn: other of under the enlightenment of the utility model, making changes, and is not limited to and the utlity model has identical or close technical scheme, all falls within the protection domain of the utility model.
