Abstract
The utility model provides a combined pin puller. The combined pin puller comprises a screw rod, a pin-pulling cylinder, a hollow hydraulic jack and a locknut, wherein one end of the screw rod passes through the locknut; the pin-pulling cylinder is sleeved outside the locknut; and the front end of the hollow hydraulic jack is sleeved outside the pin-pulling cylinder. The combined pin puller improves work reliability, greatly improves work efficiency, shortens the pin-pulling operation time to one fifth of the original work time and can prevent the pin body from being damaged in the pin-pulling process.
Description
Technical field
The utility model relates to a kind of machine tool, especially a kind of combined type pin removal.
Background technology
Along with improving constantly of Chinese large-sized machinery, electromechanical equipment design and manufacturing technology; Pinpoint all kinds of pin is used more and more widely, but in the process that adjustment and dismounting are installed, uses standard machinery instrument commonly used; Owing to can't directly extract by tool using; Both lost time, usually caused the breakage of pin again, influenced the normal function of equipment.
Summary of the invention
The purpose of the utility model provides a kind of combined type pin removal, can improve maintenance personal's operating efficiency, and the dimensional accuracy of the body of guaranteeing to pin is not destroyed.
In order to solve the problems of the technologies described above; The technical scheme of the utility model is following: the combined type pin removal; It is characterized in that: comprise screw mandrel, pull pin tube, hollow hydraulic jack, locking nut; One end of said screw mandrel penetrates in the locking nut, and the jacket casing of pulling pin is in the outside of locking nut, and the front end sleeve of hollow hydraulic jack is in the outside of pulling pin tube.
Beneficial effect:
Use the described combined type pin removal of the utility model, both improved the reliability of work, promoted operating efficiency especially greatly, make the operating time of the nail of pulling pin shorten to 1/5th of original working time, and can avoid damaging in the process of pulling pin the pin body.
Description of drawings
Fig. 1 is the sketch map of hollow hydraulic jack.
Fig. 2 is the sketch map of locking nut.
Fig. 3 be pull pin the tube sketch map.
Fig. 4 is the sketch map of screw mandrel.
The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, the utility model combined type pin removal shown in Figure 4; Screw mandrel 4, pull pin tube 3, hollow hydraulic jack 1, locking nut 2; Four unit constructions use; One end of said screw mandrel 4 penetrates in the locking nut 2, and the jacket casing 3 of pulling pin is in the outside of locking nut 2, and the front end sleeve of hollow hydraulic jack 1 is in the outside of pulling pin tube 3.
The screw thread of pulling pin that said locking nut can be reserved to the pin of different size, the locking nut of fabrication and processing different size cooperates screw mandrel, pull pin tube and the combination of hollow hydraulic jack use.At the scene in the operating process; At first be in special special-purpose locking nut, to select the locking nut that is fit to concrete pin for use; Then locking nut is connected with the pin that need extract; Be at last penetrate special-purpose screw mandrel successively, pull pin tube, hollow hydraulic jack, drive hydraulic jack pin extracted.Therefore; No matter the pin of virtually any size uses the combined type pin removal both to improve the reliability of work, promoted operating efficiency especially greatly; Make the operating time of the nail of pulling pin shorten to 1/5th of original working time, and can guarantee basically can not damage the pin body.
