Description
Technical field
The utility model relates to small tool, the especially a kind of pin removal pin squeezed in part can extracted.
Background technology
The pins such as alignment pin are conventional components of machine, and some has become the standard component in machine components.A lot of component of machine such as roll all can be provided with pin, and pin squeezes in pin-and-hole, and the diameter of pin and length scale situation difference, generally have certain assembling magnitude of interference between pin and pin-and-hole.When carrying out flight-line maintenance, needing pin to extract, and workpiece to be repaired can not be damaged when extracting pin.At present the method that pin takes out from pin-and-hole is comprised boring method, be with drill bit, pin is holed, pin is bored broken, then take out, but this method can damage workpiece to be repaired.Another kind is with special hydraulic pin remover, the part with binding clip pin being exposed surface of the work is clamped, and is then extracted by pin by hydraulic power, this hydraulic pin remover not only complex structure, and by the restriction of mechanical space, especially cannot use the pin not exposing surface of the work.
Utility model content
The utility model technical issues that need to address are to provide the simply manual pin removal of a kind of structure, also can use at narrow space, can extract the middle-size and small-size pin that the magnitude of interference is less.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of Manual pin pulling device, comprise a company's plunger be threaded connection with pin to be extracted, cross bar that contiguous block, guide rod, impact block, the block that withstands shocks impact, connecting plunger is threaded connection in contiguous block lower end, contiguous block upper end is connected with guide rod by screw thread, described cross bar is fixedly connected on the upper end of guide rod, and described impact block is socketed on the guide rod between contiguous block and cross bar.
The further improvement of technical solutions of the utility model is: described even plunger is step column structure, the cylinder of company plunger upper end is provided with the external screw thread coordinated with the inner hole thread of contiguous block, the cylinder of company plunger lower end arranges the external screw thread coordinated with the screwed hole on pin to be extracted.
The further improvement of the utility model technique scheme is: the two sections of externally threaded mid portions connecting plunger are hexagon or tetragonal stopping-receding bench.
The further improvement of technical solutions of the utility model is: the diameter of bore of impact block is greater than the diameter of guide rod.
The further improvement of the utility model technique scheme is: the diameter of bore of impact block is less than the external diameter of contiguous block, but the external diameter of impact block is greater than the external diameter of contiguous block.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
Pin pulling device structure of the present utility model is simple, also can use at narrow space.Convenient during the pin of choosing on workpiece, simple, substantially can not by the restriction of pin position, and this cover tool storage, easy to carry.Pin removal of the present utility model adopts manual mode, by the impact block of quick movable sleeving on guide rod, makes impact block clash into cross bar, utilizes the dynamic load that impact block produces, extracted by the pin that there is the magnitude of interference, do not use machine tooling from pin-and-hole.The utility model can extract the less middle-size and small-size pin of the magnitude of interference, and by the company's of replacing plunger, can realize the taking-up of the pin to different-diameter.Contiguous block of the present utility model, guide rod through threaded connect, and can change the contiguous block of different size, guide rod, especially can change the size of impact block, thus change impulsive force.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
The structure of Manual pin pulling device of the present utility model as shown in Figure 1, comprises and connects plunger 4, contiguous block 3, guide rod 5, impact block 2, cross bar 1.The structure connecting plunger 4 of the present utility model is all threaded column structures in two ends, connects the screw thread of plunger 4 one end and being threaded on pin to be extracted, and when the utility model uses, need make screwed hole in the axial direction on the end face of pin to be extracted.The cylinder of company of the present utility model plunger 4 upper end is provided with the external screw thread coordinated with the inner hole thread of contiguous block 3, the cylinder of company plunger 4 lower end arranges the external screw thread coordinated with the screwed hole on pin to be extracted.Connect plunger 4 is connected to contiguous block 3 lower end by the external screw thread of its upper end, the upper end of contiguous block 3 is connected with guide rod 5 one end by screw thread, and the upper end of guide rod 5 is fixedly connected with cross bar 1, and cross bar 1 and guide rod 5 also can be threaded connection.Described impact block 2 is socketed on the guide rod 5 between contiguous block 3 and cross bar 1.The diameter of bore of impact block 2 should be greater than the diameter of guide rod 5; And the diameter of bore of impact block 2 is less than the external diameter of contiguous block 3, the external diameter of impact block 2 should be greater than the external diameter of contiguous block 3 simultaneously, so not only convenient gripping impact block, and can not squeeze the finger of hindering operating personnel when impact block falls.
Even plunger 4 of the present utility model is step column structure, can except difference except the diameter of thread at its two ends, can also make stopping-receding bench 6 at the two sections of externally threaded mid portions connecting plunger 4, stopping-receding bench 6 is preferably hexagon or tetragonal structure, can tighten with spanner.
When using the utility model, screw thread below the company's of utilization plunger 4 is connected with the screwed hole on pin, then impact block 2 is caught with hand, impact block 2 is moved to the direction of cross bar 1 by artificial action power fast from the direction of contiguous block 3, cross bar 1 block 2 that withstands shocks impacts, thus drive pin to do minute movement, through repeatedly repeating this action, just pin can be pulled out from pin-and-hole.Different according to the screwed hole size on pin in addition, company's plunger 4 of multiple specification can be designed and produced, realized the taking-up of different pin by the mode of changing part head.Current the utility model has been applied in diameter on the multiple pin of φ less than 20, and the degree of depth that these pins load in part is generally less than 30mm, and the magnitude of interference of pin and pin-and-hole is between 0.03 ~ 0.05mm.When using the utility model to extract these pins, can smoothly pin can be extracted within the 1min time.
