Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of clamping device, is specifically related to a kind of self-locking air clamper.
Background technology
The used driving medium of air clamper is the compressed air of cleaning, thereby in use can not produce pollution.Can not be too high but air-driven fatal shortcoming is a system pressure, thereby as need to obtain just must increase the diameter of cylinder greatly than big pressure.The effective way that addresses this problem, the one, utilize mechanical booster mechanism that the power output of cylinder is amplified after, remake and be used for workpiece; The 2nd, Pneumatic Transmission and reinforcement parts such as wedge or cam with auto-lock function are made up, so that can stop supplies compressed air in process, realize energy-conservation.But above-mentioned force-increasing mechanism with auto-lock function, when pressure angle is little to a certain degree the time, the needed active force that unclamps is wanted significantly the active force that applies when clamping, and this has increased the difficulty of matching to gas pressure undoubtedly.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of self-locking air clamper is provided, and it is reasonable in design; Compact conformation, good rigidly has the two-stage force-increasing mechanism; Can significantly reduce the pressure of pneumatic system, have auto-lock function, energy-saving effect is remarkable; Production cost is low, is convenient to promote the use of.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of self-locking air clamper comprises cylinder and lever; Said lever is by drive rod and follower lever is fixed forms, and it is characterized in that: said cylinder interior is slided and is provided with rodless piston, and said rodless piston middle part is provided with axial groove; Said lever middle part is hinged on the fulcrum; Said drive rod upper end is movably arranged in the axial groove, and said follower lever lower end is movably arranged in the blind hole of wedge upside, and said wedge downside is provided with the T shape pressure head that is mated; Be provided with back-moving spring between said T shape pressure head and the support; Said cylinder one end is communicated with reversal valve P mouth through pipeline, and the said cylinder other end is communicated with reversal valve Q mouth through pipeline, and said reversal valve R mouth is communicated with the gas outlet of air pump.
The length of said drive rod is greater than the length of follower lever, and said drive rod upper end and said follower lever lower end are spherical.
Said reversal valve is a two-position four way change valve.
The utility model compared with prior art has the following advantages:
(1) this self-locking air clamper is reasonable in design, and structure is very compact, good rigidly.
(2) this self-locking air clamper has the two-stage force-increasing mechanism, can significantly reduce the pressure of pneumatic system, reduces the volume of whole system simultaneously greatly.
(3) this self-locking air clamper has auto-lock function, in the occasion that need keep active force for a long time, air pump is quit work, and energy-saving effect is remarkable,
(4) this self-locking air clamper production technology is simple, and a lot of parts all are convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.

Description of reference numerals:
The specific embodiment
A kind of self-locking air clamper as shown in Figure 1 comprises cylinder 1 and lever 3, and said lever 3 is by drive rod 3-1 and follower lever 3-2 is fixed forms; Said cylinder 1 slides within is provided with rodless piston 2; Said rodless piston 2 middle parts are provided with axial groove 2-1, and said lever 3 middle parts are hinged on the fulcrum 4, and said drive rod 3-1 upper end is movably arranged in the axial groove 2-1; Said follower lever 3-2 lower end is movably arranged among the blind hole 5-1 of wedge 5 upsides; Said wedge 5 downsides are provided with the T shape pressure head 6 that is mated, and are provided with back-moving spring 7 between said T shape pressure head 6 and the support 8, and said cylinder 1 one ends are communicated with the P mouth of reversal valve 10 through pipeline; Said cylinder 1 other end is communicated with the Q mouth of reversal valve 10 through pipeline, and the R mouth of said reversal valve 10 is communicated with the gas outlet of air pump 11.
As shown in Figure 1, the length of said drive rod 3-1 is greater than the length of follower lever 3-2, and said drive rod 3-1 upper end and said follower lever 3-2 lower end are spherical.
As shown in Figure 1, said reversal valve 10 is a two-position four way change valve.
The course of work of the utility model self-locking air clamper is: at first this self-locking air clamper is installed in the operating position, workpiece 9 is placed on the workbench.When needs clamping work pieces 9; Open air pump 11, make reversal valve 10 move to position, a left side, charged into Compressed Gas in the cylinder 1 left side cavity; Lever 3 clockwise rotates around fulcrum 4 thereby rodless piston 2 moves right drive under the effect of Compressed Gas; Wedge 5 is moved to the left under the effect of follower lever 3-2, thereby makes wedge 5 drive T shape pressure head 6 downward workpiece pressings 9, after this just can carry out cut to workpiece.Because oblique-wedge clamping system has auto-lock function, and air pump 11 is quit work, energy-saving effect is obvious.After cut is accomplished, open air pump 11, make reversal valve 10 move to right position; Charged into Compressed Gas in the cylinder 1 right side cavity; Lever 3 rotates counterclockwise around fulcrum 4 thereby rodless piston 2 is moved to the left drive under the effect of Compressed Gas, and wedge 5 moves right under the effect of follower lever 3-2, thereby makes wedge 5 unclamp T shape pressure head 6; T shape pressure head 6 moves upward under the effect of back-moving spring 7, thereby makes T shape pressure head 6 unclamp workpiece 9.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
