Abstract
The utility model discloses a pin puller, including the nut, be furnished with the screw rod mutually with the nut, the screw rod have an axial direction hole, this axial direction is downthehole to be furnished with the screw, the end nut part of screw have in the spanner of the being convenient for pivoted just, the end of screw rod have the spanner of being convenient for pivoted foreign side, the screw thread of nut and screw thread between the screw rod and screw revolve to on the contrary. The utility model discloses a when pin puller uses, utilize screw column round pin threaded connection, fixation nut uses the rotatory screw rod of spanner can extract the pin that is located the pinhole. When the cylindric lock still can't be extracted to screw rod rotation to peak, can use backing plate bed hedgehopping nut, continue rotatory screw rod and extract up to the cylindric lock. It is very convenient, easy operation, labour saving and time saving, the parts to the periphery do not exert an influence, have improved work efficiency.
Description
Technical field
This utility model relates to a kind of pin removal, and the bearing pin being positioned at workpiece hole can be extracted by this pin removal, to facilitate the dismounting of workpiece smoothly.
Background technology
At present, the design of some frame for movement is closely, when some places need detachable maintaining, due to narrow space, conventional tool cannot operation, cause needing to dismantle other positions and could dismantle the part needed repairing smoothly, both lost time, increase labor intensity, have an effect on the precision of peripheral equipment, more bother when especially bearing pin is extracted in pin-and-hole.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, easily operation, time saving and energy saving pin removal, to ensure that bearing pin is extracted in pin-and-hole smoothly, circumferential component does not produce the pin removal of impact, overcomes the deficiencies in the prior art.
Pin removal of the present utility model, including nut, screw rod it is furnished with mutually with nut, described screw rod has axial center hole, it is furnished with screw in this axial center hole, the termination nut portion of described screw has is easy to the interior side that spanner rotates, and the termination of described screw rod has is easy to the foreign side that spanner rotates, and screw thread and the thread rotary orientation of screw between described nut and screw rod are contrary.
When pin removal of the present utility model uses, utilize screw pin threaded, fixing nut, use spanner rotary screw can extract the pin being positioned at pin-and-hole.When screw rod rotates and still cannot extract straight pin to peak, the padded nut of backing plate can be used, continue rotary screw until straight pin is extracted.Very convenient, easily operate, time saving and energy saving, the parts of periphery are not produced impact, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the use status architecture schematic diagram of this utility model detailed description of the invention；
Fig. 2 is the use status architecture schematic diagram after this utility model detailed description of the invention adds backing plate.
Detailed description of the invention
As shown in Figure 1: 3 is nut, is furnished with screw rod 5 with nut 3 phase, and screw rod 5 has axial center hole, is furnished with screw 4 in this axial center hole, the termination nut portion of screw 4 has is easy to the interior side 7 that spanner rotates, and interior side 7 can be interior four directions or interior six sides.The termination of screw rod 5 has is easy to the foreign side 6 that spanner rotates, and foreign side 6 can be outer six sides or cubic outward.Screw thread and the thread rotary orientation of screw 4 between nut 3 with screw rod 5 are contrary.
When pin removal of the present utility model uses, screw 4 is utilized to be connected with the female thread of pin termination, fixing nut 3, use spanner rotary screw 5 can extract the pin 2 of the pin-and-hole being positioned at workpiece 1.When screw rod 5 rotates and still cannot extract pin 2 to peak, the padded nut of backing plate 83 can be used, continue rotary screw 4 until pin 2 is extracted.Very convenient, easily operate, time saving and energy saving, the parts of periphery are not produced impact, improve work efficiency.
