Locking mill head box sliding base press plate

Abstract

The invention discloses a locking mill head box sliding base press plate which belongs to a planer type milling machine. The locking mill head box sliding base press plate is characterized in that a left concave surface and a right concave surface are symmetrically formed on left and right parts of the front surface of a press plate body; the left concave surface and the right concave surface are positioned in the middle and lower part of the front surface of the press plate body and penetrate through the press plate body downward; the left concave surface and the right concave surface have same structures; the depth of a concave surface section of the left concave surface positioned above a long oil tank is lager than that of a concave surface section of the right concave surface positioned below the long oil tank; anti-cracking through holes are respectively drilled at tops of left and right sides of the left concave surface on the press plate body; notch long grooves are respectively, vertically and downward formed from the left and right anti-cracking through holes; a fastening through hole is formed on a concave surface section of the left concave surface positioned above the long oil tank; a circular concave surface is formed on the rear surface of the press plate body corresponding to the position of the fastening through hole; both the left concave surface section and the right concave surface section can be conducted to elastic deformation; and a bolt penetrates through the fastening through hole and is screwed into a threaded hole on a sliding base, so as to ensure that the sliding base tightly contacts with a beam, and to eliminate micro vibration caused by heavy load large cutting amount machining.

Description

technical field [0001] The invention belongs to a gantry milling machine, in particular to a pressing plate of a sliding seat of a milling head box. Background technique [0002] The main shaft milling head box of the heavy-duty gantry milling machine is installed on the slide seat. The function of the pressure plate is: it is fixedly installed on the slide seat, and forms a gap of ≤0.03mm with the side guide rail of the beam to ensure that the slide seat is smooth on the side guide rail of the beam. Running; the sliding seat and the spindle milling head box are driven by the nut installed on the sliding seat and the screw on the beam, but when the cutting amount of the spindle feed is greater than 10mm, the cutting resistance of the tool is greatly increased, which often causes the sliding seat The slight vibration between the two sides of the vertical milling head (the upper and lower sides of the vertical milling head, the left and right sides of the horizontal milling he...

Running; the sliding seat and the spindle milling head box are driven by the nut installed on the sliding seat and the screw on the beam, but when the cutting amount of the spindle feed is greater than 10mm, the cutting resistance of the tool is greatly increased, which often causes the sliding seat The slight vibration between the two sides of the vertical milling head (the upper and lower sides of the vertical milling head, the left and right sides of the horizontal milling head) and the guide rail surface of the beam (the gap is 0.03 ~ 0.02mm) can also cause the vibration of the screw and nut of the transmission mechanism and wear, which affect the processing quality of the milling machine
