Abstract
Tight spanner is pressed from both sides from excircle post of feeling relieved to roller wedge type, including spanner body, the roller, the lid is pulled, the handle, the ejector pin, a spring, adjusting screw, spanner body is last to have the three breach that has the inclined plane, the roller is packed into in this breach, spanner body sets up three mounting groove, the ejector pin is equipped with in every mounting groove, spring and adjusting screw, ejector pin one end offsets with the roller, the ejector pin other end is spacing by spanner body, the ejector pin is arranged in to the spring, between the adjusting screw, adjusting screw and spanner body groove female connection, rate of tension through adjusting screw regulating spring. The utility model has the advantages of: simple structure, low in cost, convenient operation is reliable, and the work efficiency is high, has solved the problem in the assembly well.
Description
Technical field
This utility model relates to a kind of acting clamping wrench.
Background technology
When assembling molding machine, through being commonly encountered such problem: piston will be screwed in piston rod, common wrench can not be used owing to outside piston is smooth, due also to piston diameter is very big, the most both greater than 120MM, also can use without general utility tool, so have to load by artificial means, low being not easy to of work efficiency screws.Also some axial workpiece axle external diameter is generally between 100-300MM, time in workpiece to be loaded, have on axle cylindrical two facets of milling, then block two facets with special spanner and screw in.By two facet methods of milling, not only take a lot of work, increase cost, also reduce the intensity of workpiece, and some workpiece the most do not allow milling auxiliary plane.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of roller wedge-type self-centering outside cylinder acting clamping wrench to solve the problems referred to above so that it is can conveniently load the workpiece such as piston.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is:
Roller wedge-type self-centering outside cylinder acting clamping wrench, pull including wrench body, roller, lid, handle, push rod, spring, regulation screw, three are had to carry bevelled breach on wrench body, roller loads in this breach, wrench body arranges three mounting grooves, equipped with push rod, spring and regulation screw in each mounting groove, push rod one end offsets with roller, the push rod other end is spacing by wrench body, spring is placed between push rod, regulation screw, regulation screw is connected with wrench body groove female thread, by the rate of tension of regulation screw regulation spring.
Roller is guided by the groove being arranged on the wrench body guiding breach limit, and such roller will not drop out.
This utility model utilizes three inclined-planes and three rollers, according to law of friction and the self-lock mechanism of A Mangtang-coulomb, is clamped with three rollers by excircle of workpiece, then is screwed in the assembly being assembled by workpiece.
The utility model has the advantage of: simple in construction, cheap, convenient and reliable operation, work efficiency is high, solves the problem in assembling well.
This utility model is applied widely, can be used for the assembling of any cylindrical pillar workpiece, is particularly well-suited to the workpiece that outside diameter is big.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the left view part sectioned view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is further described.
As shown in Figure 1 and Figure 2, roller wedge-type self-centering outside cylinder acting clamping wrench, pull 3 including wrench body 1, roller 2, lid, handle 4, push rod 5, spring 6, regulation screw 7.
Having three to carry bevelled breach 11 on wrench body 1, roller 2 loads in this breach 11, and when spanner loads workpiece 9, roller 2 cylindrical contacts with workpiece 9 cylindrical.
At wrench body 1, three mounting grooves 12 are set, equipped with push rod 5, spring 6 and regulation screw 7 in each mounting groove, push rod 5 one end offsets with roller 2, push rod 5 other end is spacing by wrench body 1, spring 6 is placed between push rod 5, regulation screw 7, regulation screw 7 is connected with wrench body 1 groove female thread, can be regulated the rate of tension of spring 6 by regulation screw 7.
As in figure 2 it is shown, roller 2 is guided by the guiding groove 13 being arranged on the wrench body 1 guiding breach 11 limit, such roller 2 will not drop out.
When spanner loads workpiece, spanner counterclockwise turns, and roller 2 oppresses spring 6 to move to the direction that trough is wide, and the external circle diameter increase that three rollers are formed, workpiece enters spanner inner chamber.Then roller 2 makes roller move to the direction that trough is narrow to make roller contact excircle of workpiece and wrench body under spring 6 and push rod 5 act on simultaneously, at this moment handle moves in the direction of the clock, roller moves to the narrow end of groove under wrench body inclined-plane drives, roller is tightly stuck between workpiece and wrench body inclined-plane, makes workpiece rotate and is tightened in the assembly being assembled.Handle is the most past rotationally clockwise, and workpiece stress is the biggest.Owing to being self-locking between roller and excircle of workpiece and wrench body, so skidding will not be produced between roller and workpiece.Clamping workpiece back handle is towards turning counterclockwise, and roller moves toward groove width direction, unclamps workpiece and spanner is taken out.
