Description

A kind of tower crane standard knot machine tool special for numerical control machining on chip

Technical field

The utility model relates to a kind of machining apparatus field, in particular to a kind of tower crane standard knot numerical control processing on chip is special Use lathe.

Background technique

Tower crane standard knot on chip is the important component of tower crane, and quantity is very big, therefore, the processing quality of such part with Efficiency is related to the productivity effect of tower crane manufacturer, is each producer in the production difficult point solved energetically.Tower crane it is steady Qualitative relationships the progress of engineering and the safety problem of construction personnel, and tower crane mounting height is generally higher, so the peace of tower crane It is extremely important to fill stability.And tower crane is made of tower crane standard knot one by one, therefore, to the pilot hole of tower crane standard knot Relative position require it is very high.

After all tower crane producers are all the first hole machined bulk-breaking each on standard knot monolithic, according still further to drawing handle Each bulk-breaking group weldering is got up.The Chinese patent for authorizing 107775041 A of publication number CN, discloses a kind of main string of tower crane standard knot Bar drill Special-purpose machine tool for boring, data of publication of application 2018.03.09.Including main bed body, first longitudinal direction bed body, second longitudinal direction bed body, Show that column is arranged in third longitudinal direction bed body, main bed body left end, column is fixed with main bed body relative position, set in column right side Upright guide rail is set, column bores boring head and is slidably connected by sliding block and guide rail, and column bores boring head and relies on chain gear transmission machine Structure driving can be slided up and down along guide rail.It is characterized by: showing that the first slide unit, the first slide unit is arranged in the first longitudinal direction bed body Upper setting first longitudinal direction bores boring unit, and first longitudinal direction bores the brill boring head that boring unit includes the arrangement of 1 vertical equity, first longitudinal direction Bore boring head can driving device driving under can be along the first slide unit in longitudinal movement；Second longitudinal direction bed body upper surface setting the Two slide units, setting second longitudinal direction bores boring unit on the second slide unit, and it includes three vertical equities arrangements that second longitudinal direction, which bores boring unit, Boring head is bored, this three brills boring head positions relative to each other fix, and second longitudinal direction bores boring unit can in the case where driving device drives Longitudinal movement is done along the second slide unit；Third slide unit is arranged in the third longitudinal direction bed body upper surface, and setting third is vertical on third slide unit To boring unit is bored, third longitudinally bores the brill boring head that boring unit includes the arrangement of 2 vertical equities, this 2 brill boring heads phase each other Position is fixed, third, which longitudinally bores boring unit, can do longitudinal movement along third slide unit under driving device driving.Standard knot The pilot hole of main chord process, and can guarantee the precision of each processed hole relative position.However it is such the disadvantage is that Thermal deformation occurs after welding, the position for causing each hole mutual changes, thus keep the size of entire monolithic inconsistent, No interchangeability is caused, monolithic is even resulted in and scraps.

Utility model content

In view of the deficiencies in the prior art and defect, the utility model provides a kind of tower crane standard knot numerical control on chip Special Purpose Machine for Processing is by each bulk-breaking on monolithic by drawing assembly welding shaping, after thermal deformation, then standard knot monolithic is whole Body is placed on the processing that the lathe carries out each hole.The influence that monolithic is processed in thermal deformation is thus avoided that, to ensure that dress The relative position of distribution it is accurate, ensure that processing quality.In addition, the lathe is assembled with 4 main shafts, in same coordinate (length Direction) hole can be processed simultaneously, substantially increase machining efficiency.

In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution: including rack, mobile work Platform, Men Liang are equipped with workpiece positioning clamp on the movable working platform, and main shaft I, main shaft II, main shaft III are equipped on door beam, The main shaft I, main shaft II are connect with door beam by slide rail, can be moved left and right.The main shaft I can pass through driving device Milling head I is driven, the main shaft II can drive milling head II by driving device, and main shaft III is on the column of door beam, by chain Gear drive can be slided up and down along guide rail, and the main shaft III is by that can drive milling head III by driving device.Main shaft IV Behind door beam, the main shaft IV can drive milling head IV by driving device.

The mobile work is equipped with workpiece positioning clamp as a further improvement of the utility model, clamps workpiece Tower crane standard knot monolithic, and make each machined surface face milling head.

The milling head III is combined with milling head II (moving left and right can be longitudinally displaced) as a further improvement of the utility model, Mismatch synchronization processing is carried out to 4 macropores.

The milling head III and milling head I (move left and right can longitudinally same position) combine as a further improvement of the utility model, 10 apertures process with bit synchronization.

The milling head IV is a longitudinal horizontal-milling head as a further improvement of the utility model, behind door beam, The end face of tower crane standard knot monolithic can be processed.

The end mill head I can carry out 2 apertures on attachment angle steel as a further improvement of the utility model, Processing.

Compared with prior art, the utility model has the beneficial effect that the lathe is to the standard knot list after welding Piece carries out overall processing, is notheated the influence of deformation, can accurately process the opposite of each pilot hole in tower crane standard knot Position, ensure that the overall precision of monolithic, and then ensure the safety of tower crane.It can be added simultaneously in the hole of same coordinate Work substantially increases the efficiency of machining.
