Abstract

The invention discloses a lifting type clamping tool. A clamping device comprises a base and two right-opposite clamping blocks on the base. The opposite side faces of the two clamping blocks are provided with clamping sliding plate mounting seats. A first guide sliding groove with the inner end inclined outwards and a second guide sliding groove with the inner end inclined outwards are formed in the clamping sliding plate mounting seats respectively. Clamping sliding plates are arranged in the two guide sliding grooves. Connecting columns are arranged at the lower ends of the clamping sliding plates. The lower ends of the connecting columns are hinged to a connecting cross rod. A longitudinal lifting rod is arranged below the connecting cross rod. A lead screw is sleeved with a lead screw groove in the longitudinal lifting rod. The upper end and the lower end of the longitudinal lifting rod are fixedly connected with the connecting cross rod and a lead screw nut respectively. The lower end of the lead screw penetrates the base and is hinged to the base. A worm is arranged in the base. A worm gear meshed with the worm is fixedly arranged on the lead screw in a sleeving manner. A rocker arm is arranged at one end of the worm. Rotation movement of the worm is converted into vertical movement of the clamping sliding plates through the structure of the worm and the lead screw, and semi-automatic control over rotor clamping is achieved.

Description

Lift clamping tooling
Technical field
The present invention relates to machining tool clamp field, be specifically related to a kind of lift clamping tooling.
Background technology
Compressor is a kind of driven fluid machinery low-pressure gas being promoted to gases at high pressure, it is the heart of refrigeration system, it sucks the refrigerant gas of low-temp low-pressure from air intake duct, after driving piston to compress it by motor rotation, the refrigerant gas of HTHP is discharged to blast pipe, for kind of refrigeration cycle provides power, thus realize the kind of refrigeration cycle of compression → condensation (heat release) → expand → evaporate (heat absorption), and the core component of compressor movement rotor whole compressor operating especially, tradition processing rotor blade groove time generally adopt hand-operated clamping mode, artificial clamping is not only wasted time and energy and be the more important thing is that reliable clamping degree affects seriously by operating personnel's professional ability, and once the qualification rate that rotor machining front clamp reliability not only affects product more likely jeopardizes the life security of operating personnel.
Summary of the invention
For solving above technical problem, the invention provides a kind of without the need to hand-operated clamping and can realize rotor processing installing clamp semi-automation control lift clamping tooling.
Technical scheme is as follows:
A kind of lift clamping tooling, comprise clamping device, its key is: described clamping device comprises base, described base is provided with two clamping blocks, two described clamping blocks are just to setting, the side that two these clamping blocks are relative is all fixed with clamping slide plate mount pad, described clamping slide plate mount pad is respectively equipped with the first guide chute and the second guide chute, be respectively arranged with clamping slide plate in described first guide chute and described second guide chute, described first guide chute and described second guide chute are the outward-dipping skewed slot in upper end, described clamping slide plate lower end is respectively equipped with joint pin, described joint pin lower end is respectively with to be connected cross bar two ends hinged, longitudinal elevating lever is provided with below described connection cross bar, described longitudinal elevating lever bottom is provided with screw mandrel groove, screw mandrel is movably installed with in described screw mandrel groove, described screw mandrel is provided with feed screw nut, described longitudinal elevating lever upper end is fixedly connected with the described cross bar that is connected, described longitudinal elevating lever lower end is fixedly connected with described feed screw nut upper end, described screw mandrel lower end is through described base hinged with described base, worm screw is provided with in described base, described screw mandrel is fixed with turbine, described worm screw engages with described turbine, the side of described base is provided with rocking arm, a linking arm of described rocking arm is fixedly connected with one end of described worm screw.When adopting the beneficial effect of this programme to be shake rocking arm, worm screw can drive screw mandrel generation gyration, feed screw nut can change into upper and lower rectilinear motion with the rotational angle of screw mandrel according to the helical pitch of corresponding specification, corresponding rising or decline also drive clamping slide plate to slide in guide chute by longitudinal elevating lever further that be at this moment fixedly connected with to feed screw nut, due to guide chute be skewed slot thus make clamping slide plate in moving up and down mutually away from or near thus loosen or clamp rotor.
As preferably: above-mentioned first guide chute is consistent with the angle of inclination of described second guide chute, the beneficial effect of this programme is adopted to be that the clamping slide plate of both sides can apply chucking power in opposite directions to rotor simultaneously thus make clamping more solid and reliable when moving up or down.
Above-mentioned feed screw nut is positioned at above described base, adopts the beneficial effect of this programme to be that the range of movement of feed screw nut is larger, thus expands the workpiece size scope that clamping device can clamp.
Above-mentioned clamping slide plate mount pad is separately positioned on the top of described clamping block, and the beneficial effect adopting this programme is conducive to the processing of milling machine to rotor.
The axial line of above-mentioned connection cross bar, longitudinal elevating lever and described screw mandrel is overlapping, adopt the beneficial effect of this programme to be that longitudinal elevating lever passes to the power of both sides clamping slide plate when moving up and down in the same size, the stability of transmission better effects if whole clamping device is simultaneously also better.
Beneficial effect: adopt worm screw when the invention has the beneficial effects as follows shake rocking arm can drive screw mandrel generation gyration, feed screw nut will change into upper and lower rectilinear motion with the rotational angle of screw mandrel according to the helical pitch of corresponding specification, corresponding rising or decline also drive clamping slide plate to slide in guide chute by longitudinal elevating lever further that be at this moment fixedly connected with to feed screw nut, due to guide chute be skewed slot thus make clamping slide plate in moving up and down mutually away from or near thus loosen or clamp rotor, thus achieve the semiautomatic control of rotor clamping, avoid manually-operated uncertainty.
