Description

A kind of novel hydraulic pin removal
Technical field
The utility model relates to mechanical assembly technique field, especially a kind of novel hydraulic pin removal.
Background technology
For the dismounting that straight pin connects, traditional method for dismounting has crowbar method by lever principle and old-fashioned impact type pin removal.This method of two kinds not only bothersome effort, and once misoperation easily causes the damage of personnel.Simultaneously, adopt the stressed and axis of straight pin during crowbar method to there is certain drift angle, the strength of impact type pin removal is also that interrupted fluctuating is indefinite, so all there is damage to straight pin and part, pin-and-hole after dismounting cannot be used, thus must pin-and-hole be strengthened and again purchase large size straight pin.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of simple operation, safe and reliable, to part and the undamaged novel hydraulic pin removal of straight pin.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel hydraulic pin removal,
Comprise the straight pin be connected with part, the top of described straight pin has screwed hole,
Comprise an annular hydraulic cylinder, there is in the middle part of described annular hydraulic cylinder the tubular connecting portion of hollow, in described tubular connecting portion, screw rod of pulling pin is installed, described in the pull pin external screw thread of screw rod be engaged mutually with the internal thread of above-mentioned screwed hole.
Further, described annular hydraulic cylinder comprises annular hydraulic cylinder body and is positioned at the annular piston that annular hydraulic cylinder body is slidably matched with it.
The beneficial effects of the utility model are: the utility model is easy and simple to handle, and use and maintenance expense is low; Safe and practical, to part and pin not damaged, lossless, ensure that the reusability of straight pin and part.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. straight pin, 2. screwed hole, 3. annular hydraulic cylinder, 4. tubular connecting portion, screw rod of 5. pulling pin, 31. annular hydraulic cylinder bodies, 32. annular pistons.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of novel hydraulic pin removal, comprise the straight pin 1 be connected with part, the top of straight pin 1 has screwed hole 2, comprise an annular hydraulic cylinder 3, have the tubular connecting portion 4 of hollow in the middle part of annular hydraulic cylinder 3, be provided with screw rod 5 of pulling pin in tubular connecting portion 4, the external screw thread of screw rod 5 of pulling pin is engaged mutually with the internal thread of above-mentioned screwed hole 2.
In the present embodiment, annular hydraulic cylinder 3 comprises annular hydraulic cylinder body 31 and is positioned at the annular piston 32 that annular hydraulic cylinder body 31 is slidably matched with it.
During concrete operations, screw rod 5 of pulling pin is through in the middle of annular hydraulic cylinder 3, and screw rod 5 of pulling pin inserts in screwed hole 2 and screws, then is extracted by straight pin 1 by the pressure that moves back of the continuous uniform of annular hydraulic cylinder 3.The method compares two kinds of old-fashioned method simple operations, safe and reliable, to part and straight pin 1 not damaged, ensure that the reusability of straight pin 1 and part.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
