Description
Technical field
The invention belongs to machine tool element technical fields, more specifically to a kind of Novel ground boring machine.
Background technique
During workpieces processing, the ram front end of lathe needs to pacify NC heavy floor type boring and milling machine according to processing request
The attachment of different weight is filled to meet the processing request of workpiece.The ram of lathe make in spindle box it is forward and backward move horizontally, they
The distance stretched out from spindle box is generally all bigger, and maximum moving distance can reach 1.2m or more, and some for user
On the NC heavy floor type boring and milling machine series of products of specific customization, this parameter can be bigger.In outreach situation long in this way
Under, and ram front end is also equipped with accessory head, some weights of attachment are even more heavy up to 2~3 tons, in this way, ram component adds again
On the accessory head installed actually be equivalent to a cantilever beam 2~3 tons of accessory head added to overhang outside spindle box, ram
Component is bigger because of the amount of deflection bending deformation generated along with accessory head weight of being self-possessed, so that ram component system be made to exist
May be excessive due to amount of deflection bending deformation in process, cause mismachining tolerance, reduce the machining accuracy of lathe, makes to process
Design requirement is not achieved in the Product Precision and surface quality come.Therefore, when NC heavy floor type boring and milling machine designs and produces, have
Necessity is installed the amount of deflection bending deformation generated after accessory head because overhanging is too long to ram front end and is compensated.In actual processing system
Make and production process in, to solve the above problems, usually needing to improve the rigidity of ram system, example using some auxiliary devices
Such as: guiding reinforcing rod being installed for ram；Or the contact stiffness of ram itself is improved, closed hydrostatic slideway is such as used, and use
A cam mechanism is respectively adopted on the rear end of bearing surface on the front end of spindle box ram lower support surface and ram, outside ram
When stretching, front cam carries out " upper lift " to ram, and rear cam, which carries out " pushing " to ram, to be made to keep straightened condition when ram is overhanging.On
The use for stating these auxiliary devices and technical measures, ram system stiffness and reduction amount of deflection when stretching out spindle box to ram component
Bending deformation has certain effect, but all there is structure is complicated, required precision is high, difficulty of processing and assembling is big and uses cam machine
