Abstract
A heavy numerical control screw press machine body beam and support arm composite connecting device is characterized by comprising a machine body beam, a left support arm and a right support arm, wherein the left support arm and the right support arm are arranged on the machine body beam through a composite connecting mechanism; the composite connection mechanism comprises a plurality of upper end cylindrical pins and a plurality of upper end flat keys which are arranged at the contact positions of the upper end surfaces of the machine body beam, the left support arm and the right support arm, a plurality of cross keys which are arranged at the contact positions of the machine body beam, the left support arm and the right support arm, and a plurality of fastening bolts which fasten and connect the machine body beam, the left support arm and the right support arm. The utility model discloses heavy numerical control screw press fuselage crossbeam and support arm composite connection device, multiple connection, it is fixed reliable. The double-stage balance type heavy numerical control screw press can be widely applied to heavy numerical control screw presses, and is particularly applied to 125000kN screw rod slide block two-stage balance type heavy numerical control screw presses.
Description
Technical Field
The invention relates to a heavy numerical control screw press body cross beam and support arm composite connecting device which can be widely applied to a heavy numerical control screw press, in particular to a 125000kN screw rod slide block two-stage balance type heavy numerical control screw press.
Background
The existing connecting structure of the cross beam of the machine body, the left support arm and the right support arm is only connected by bolts. In this connection mode, once the bolt and the nut are loosened, the connecting piece can be loosened, the problem of cutting off the bolt is caused, and the normal use of equipment is influenced.
Disclosure of Invention
The invention aims to provide a composite connecting device for a cross beam and a support arm of a machine body of a heavy numerical control screw press, which is multi-connected and reliable in fixation.
In order to achieve the purpose, the heavy numerical control screw press machine body beam and support arm composite connecting device comprises a machine body beam, a left support arm and a right support arm, wherein the left support arm and the right support arm are arranged on the machine body beam through a composite connecting mechanism; the composite connection mechanism comprises a plurality of upper end cylindrical pins and a plurality of upper end flat keys which are arranged at the contact positions of the upper end surfaces of the machine body beam, the left support arm and the right support arm, a plurality of cross keys which are arranged at the contact positions of the machine body beam, the left support arm and the right support arm, and a plurality of fastening bolts which fasten and connect the machine body beam, the left support arm and the right support arm.
The invention relates to a heavy numerical control screw press body crossbeam and support arm composite connecting device, which has the working principle that: the composite connection structure is adopted, and firstly, the connection firmness of the cross beam of the machine body and the upper end surfaces of the left support arm and the right support arm is enhanced by adopting a plurality of upper end cylindrical pins and a plurality of upper end flat key connection structures, so that the support arm is more stable after being installed on the cross beam, and the equipment damage caused by loosening of nuts on the support arm due to horizontal movement of the support arm can be prevented; secondly, the plurality of cross-shaped keys arranged at the contact positions of the cross beam of the machine body and the side surfaces of the left support arm and the right support arm strengthen the connection firmness of the cross beam of the machine body and the side surfaces of the left support arm and the right support arm, can prevent the side surfaces of the support arms from moving up and down and back and forth when being installed and contacted, and increase the connection firmness; and finally, the cross beam of the machine body, the left support arm and the right support arm are fastened and connected together through a plurality of fastening bolts. Through the multiple composite connection structure, the phenomenon of cutting off the bolt can not occur, so that the two are reliably connected and fixed.
In conclusion, the heavy numerical control screw press body cross beam and support arm composite connecting device is in multiple connection and reliable in fixation.
