Abstract
The utility model provides a pin removal device, which comprises a pin removal shaft and a punch hammer that is sleeved on the pin removal shaft, and also comprises a base that is connected with one end of the pin removal shaft and a screw that is arranged inside the base, wherein, one end of the pin removal shaft suppresses the head part of the screw. The device can fix the screw, and can save time and power during the application process.
Description
Technical field
The utility model relates to a kind of maintenance of equipment instrument, particularly relates to a kind of pin removal that is used to dismantle pin.
Background technology
In the process of maintenance of equipment, often need a plurality of pins of dismounting, as the Chinese patent application application number is that CN200420079312 discloses a kind of pin removal, comprise pull bar, block stamp, nut sleeve and screw, screw passes the endoporus of the pullover inside of nut, there are inside and outside two openings of different sizes nut sleeve head the same side, inner beginning is bigger, width is a bit larger tham the head of screw diameter, highly be a bit larger tham the head of screw height, outer opening is less, and width is a bit larger tham the head of screw diameter, height is consistent with the female cover of sieve head endoporus degree of depth, and screw head is stuck on the endoporus step.Screw cooperates with pin, by the gravity of block stamp, the dismounting pin, but because the nut sleeve head has opening, width all is a bit larger tham the head of screw diameter, screw is easy to slide in opening and can't fixes, and screw is with after pin is connected, in case screw moves along opening in the opening of nut sleeve head, screw and pin have certain angle, in the unloading process, it also is along certain angular movement that the gravity of block stamp drives screw pulling pin, and pin will very difficultly just can be extracted.
Summary of the invention
The purpose of this utility model be to provide a kind of can hold-down screw, time saving and energy saving pin removal.
A kind of pin removal of the present utility model comprises pull pin axle and the block stamp that is set on the axle of pulling pin, also include and pull pin axle one end pedestal that is connected and the screw that is located in the pedestal, and an end of the axle of pulling pin compresses on the head of described screw.
The utility model is compared with prior art: the screw that cooperates with pin, by pedestal with pull pin the axle be threaded, housing screw, screw is not rocked in pedestal, in the unloading process, the gravity of block stamp drives screw pulling pin, and screw and pin can not produce certain angle, and unloading process is time saving and energy saving.
Description of drawings
The structural representation of a kind of pin removal that Fig. 1 provides for the utility model.
The specific embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
As shown in Figure 1, a kind of pin removal that the utility model provides, comprise pull pin axle 1 and the block stamp 2 that is set on the axle 1 of pulling pin, described block stamp 2 can slide along the described axle 1 of pulling pin, also include and axle one end pedestal 3 that is connected and the screw 4 that is located in the pedestal 3 of pulling pin, the end of axle of pulling pin compresses the head 41 of described screw, is connected with the pin that needs to dismantle by screw 4.Block stamp 2 slides along the axle 1 of pulling pin, and bump is fixed with the object of pin, and the screw 4 on the pin removal is connected with this pin thread, by the impact of block stamp 2, makes pin along with screw 4 moves up, thereby extracts pin.
Be provided with the stepped hole 31 that runs through in the described pedestal 3, stepped hole 31 comprises stage portion 311, the big portion 312 of diameter and diameter smaller part 313, described screw 4 passes the diameter smaller part 313 of stepped hole 31, the head 41 of screw cooperates with the stage portion 311 of stepped hole 31, and an end of the axle 1 of pulling pin is connected with the big portion 312 of the diameter of stepped hole.The pedestal 3 that is provided with stepped hole is arranged and pass described stepped hole, the screw that cooperates with described stage portion.The big portion 312 of the diameter of stepped hole 31 is provided with screw thread in the preferred case, is connected with the threaded one end of the axle 1 of pulling pin.
This pin removal also comprises push rod 5, and 5 one ends of described push rod are connected with an end of the axle 1 of pulling pin, and its other end is connected with pedestal 2, compresses the head 41 of described screw.
The specific embodiment of the above is a better embodiment of the present utility model, is not to limit concrete practical range of the present utility model with this, and scope of the present utility model comprises and is not limited to this specific embodiment; The equivalence variation that all shapes according to the utility model, structure are done all comprises in the protection domain of the present utility model.
