Clamp mechanism is taken in the disclosed fluorescent tube moulding of Chinese patent CN2142460, and structure is then very complicated.The disclosed fluorescent lamp bridging fixed clamping device of Chinese patent CN2828032, the employing telescopic cylinder is fixed, whether be new hand, emotion influence, all can guarantee accurately, fix to clamp fast, and can realize automated operation if making tube clamping not reached by operative employee's level.Yet cylinder clamping, every clamping cylinder, all need be equipped with corresponding solenoid valve, the time relay and corresponding connection electric wire and tracheae, for operating as gap displacement multi-work-station, Chinese patent CN1092204 for example, CN2731697, CN1862750, the CN101051585 plane clearance rotates and connects bridge, with Chinese patent CN101037293 multi-work-station rolling bridging apparatus, and the vertical squeezing machine of Chinese patent CN2457737 station dial, because of multi-work-station uses the clamping cylinder amount many, causing needs to be equipped with relatively large magnetic valve, the time relay, especially clamping device is arranged on the rotating mechanism of multi-work-station gap, supply with source of the gas and power supply and connect complexity, cause equipment very complicated.Besides, cylinder compresses in addition that a deficiency is, because of cylinder miles of relative movement is provided with fixingly, then can plays better clamping action for standard pipe, but have deviation for caliber, then can cause tubule to compress inadequately, and bassoon compresses excessive and crushed.Therefore still having is worth improved place.

The utility model content

The utility model purpose is to overcome the deficiency of above-mentioned prior art, provides a kind of can the realization to compress automatically and unclamp, and need not each outfit cylinder and corresponding accessory separately, is specially adapted to the fluorescent tube bulb processing clamping device of multi-station operator.

The utility model purpose realizes, the main improvement is to adopt the parallel rack difference structure, as compressing and the unclamp operation bar, and give a preset condition (compress or unclamp) by spring, by the external force pushing tow or draw back (comprise rotate crimping), realization is in contrast to spring preset condition action, compresses automatically and unclamps thereby reach to adapt to, and realizes the utility model purpose.Specifically, utility model fluorescent tube bulb processing clamping device, comprise fixed lamp tube carriage and mobile hold-down gear, it is characterized in that the revolving gear of said mobile hold-down gear, and wherein form by the pretension spring at least one tooth bar by tooth bar about two alternate parallel racks and the middle engagement.

Two alternate parallel racks and middle revolving gear can be located by pernetti or box body, make two tooth bars be differential relatively under neutral gear rotates, and realize moving axially stretching, contracting, and fluorescent tube is carried out clamping compress, unclamp.

According to the difference of spring pretension, utility model fluorescent tube bulb processing clamping device can have normally to compress or normally unclamp two kinds of structure formations, gives a tooth bar external force, then realizes and the pretension opposite action.

Giving a tooth bar external force, according to the processing unit (plant) design, can be cylinder then, also can be lever, can also be in rotation or moving process, contacts with the different radii segmental arc that fixedly installs, make tooth bar produce axial different distance according to this and change, thereby realize and spring pretension opposite action.

Change different fixing fluorescent tube carriage and compress tooth bar head hold-down head, can be used for the compression clamping of different fluorescent tubes.

Utility model fluorescent tube bulb processing clamping device, because adopt parallel rack, neutral gear is differential and spring pretension structure, make that mobile hold-down gear is simple in structure, reliable in action is accurate, need not each and be equipped with cylinder and corresponding accessory separately, just can realize processing compressing automatically and unclamping of fluorescent tube, be specially adapted to multi-station operator and compress as tube clamping.And compress miles of relative movement and preset, thereby the deviation fluorescent tube is arranged, still can effectively clamp, also can not damage fluorescent tube for caliber by spring force.The utility model holding device of strip lamp, clamp, unclamp and only be unidirectional translational motion, thereby be particularly suitable for being disposed at the multi-station operator that rotates in the gap and make holding device of strip lamp, as long as outside the needs compressor arm is in reverse to the spring force motor point, the segmental arc that thrust device (for example fixedly cylinder or other similar functions parts) maybe can produce different axial distances is set, just can be implemented in when going to this, make clamping device realize being in reverse to the spring force action, clamp or unclamp spot, can realize that the cylinder of operation compresses automatically, omitted complicated tracheae, electric wire and supporting magnetic valve, parts such as the time relay have simplified the entire machine structure greatly.

Below in conjunction with two specific embodiments; utility model is understood in exemplary illustration and help; but embodiment only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the qualification to the utility model technical scheme, some do not depart from the unsubstantiality of utility model design and change In the view of the technician; simple change or replacement with same or similar technique effect are all truely used novel protected scope.
