Wherein: 10, installing rack; 11, bellmouth; 20, tumbler; 21, compressed part; 30, the first ball; 40, connector; 41, end is plugged; 412, screens hole; 50, part is turned; 51, hand grip portion; 60, frame.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figures 1 to 4, the utility model improvement type hold-down mechanism, is installed in frame 60, and this improvement type hold-down mechanism comprises installing rack 10, tumbler 20, first ball 30, connector 40 and turns part 50.Installing rack 10 is fixedly arranged in frame 60, and installing rack 10 is provided with up-narrow and down-wide bellmouth 11; One end of tumbler 20 is articulated with on installing rack 10, the other end is provided with compressed part 21 for workpiece pressing; Connector 40 is fixedly arranged on tumbler 20, the lower end of connector 40 is provided with to be inserted in and plugs end 41 in bellmouth 11, the inside plugging end 41 is provided with the container cavity for holding the first ball 30, the sidewall plugging end 41 is provided with the screens hole 412 being communicated in container cavity, first ball 30 is arranged in screens hole, connector 40 is provided with and axially extends along it and to be communicated in the through hole of container cavity; Turn part 50 to be installed in through hole and to be threaded with connector 40, turn part 50 has for by the first ball 30 along the top splenium (not shown) of radially outward pushing up pressure plugging end 41.
The utility model is when workpiece pressing, rotate compressed part 21 workpiece pressing, making to plug end 41 is inserted in bellmouth 11, rotation turns part 50 and makes to turn part 50 and move downward relative to connector 40, thus by the first ball 30 along the radially outward top pressure plugging end 41, due to exposing of the first ball 30, make to plug end 41 and be arranged in bellmouth 11, just complete the compression action of workpiece; When needs unclamp workpiece, rotate backward and turn part 50 and make to turn part 50 and move upward relative to connector 40, thus make the medial surface of the first ball 30 no longer by top pressure, upwards rotate compressed part 21 and drive and plug end 41 and move upward, at this moment because the medial surface of the first ball 30 does not have pressure on top surface, the first ball 30 when encountering the madial wall of bellmouth 11, just in retraction container cavity, make to plug end 41 to depart from from bellmouth 11, thus complete workpiece unclamp action.
The utility model is when workpiece pressing, utilizing tumbler 20 to rotate relative to installing rack 10 makes compressed part 21 be pressed on workpiece, again rotate turn part 50 just can just the first ball 30 along plug end 41 radially outward top pressure, so just, secure and plug end 41 and bellmouth 11, complete the compression action of workpiece; When needs unclamp workpiece, direction is rotated and is turned part 50, lay down the pressure on top surface inside the first ball 30, during the compressed part 21 that moves up like this, first ball 30 is when encountering the madial wall of bellmouth 11 just in retraction container cavity, and making to plug end 41 can depart from from bellmouth 11, thus complete workpiece unclamp action, the firm position when workpiece pressing like this, operates comparatively simple when unclamping workpiece.
As preferred embodiment, this improvement type hold-down mechanism also comprises impeller (not shown), and impeller is arranged in through hole, and impeller is used for being pressed down by the top splenium turning part 50 medial surface promoting the first ball 30.As other embodiments, top splenium also immediate roof can press the medial surface of the first ball 30.
Preferably, the first ball 30 has many, encloses and is contained in container cavity, and impeller or pushing part are aligned in the hole that many first balls 30 surround, and the volume of impeller or top splenium should be greater than the hole that many first balls 30 surround.
Again preferably, impeller is the second ball, be positioned at many first balls 30 top and by many first ball 30 common support.
Further, turn the upper end that part 50 is positioned at connector 40 outside and be provided with hand grip portion 51, like this, handled easily personnel hold.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
