The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to accompanying drawing, the lowering or hoisting gear of novel automatic multiple-head adjustable row-hole drilling machine and pitch-row adjustment structure, comprise lowering or hoisting gear and pitch-row adjustment structure, it is characterized in that: described lowering or hoisting gear comprises hydraulic cylinder base 2, hydraulic cylinder 3, lifting platform base 5, lifting platform 6, connecting plate 7; Described hydraulic cylinder base 2 is fixed by screws on lathe bed 1, is provided with hydraulic cylinder 3 on hydraulic cylinder base, and hydraulic cylinder piston rod is connected with lifting platform base 5 upper junction plates 7, and lifting platform base 5 is fixed together by screw and lifting platform 6; Described pitch-row adjustment structure, comprise roll adjustment spline shaft 9, boring anchor 10, Hough cover 11, nut 12, screw rod bushing 13, thrust ball bearing 14; Be arranged with several boring anchors 10 on described roll adjustment spline shaft 9, each boring anchor 10 right-hand member inner chamber is provided with thrust ball bearing 14; The left end inner chamber is provided with nut 12, and by junction of the edges of two sheets of paper screw, is fixed on boring anchor, and nut 12 screws mutually with the screw rod bushing 13 that is set on the roll adjustment spline shaft, is provided with Hough cover 11 between screw rod bushing 13 right-hand members and right side boring anchor inner bearing.Be respectively arranged with arc cam and circular groove on the faying face of described Hough cover 11.During concrete enforcement, the utility model pitch-row adjustment structure needs any distance of adjusting between machining hole and hole according to the user, by being arranged on the scale on the auger spindle of location, distance between the controlled working hole, be rotatably provided in the handwheel of roll adjustment spline shaft right-hand member during adjustment, adjust the distance between right-hand member location auger spindle and second auger spindle, and according to scale, regulate arbitrarily.When the pitch-row of workpiece is large, do not need to dismantle other part on the roll adjustment spline shaft, only need the distance between rotation hand wheel increase boring anchor, arc cam and circular groove are stuck and get final product with the Hough cover split is involutory from roll adjustment spline shaft both sides, then according to scale by roll adjustment screw fine setting pitch-row in a boring anchor; When the pitch-row hour of workpiece, the Hough cover that only needs to split pulls open from the roll adjustment spline shaft, and rotation hand wheel shortens the distance between boring anchor, then according to scale, by roll adjustment screw in individual boring anchor, finely tunes pitch-row again.Adopt hydraulic cylinder in the situation that with the same cylinder diameter of gas-liquid damping cylinder, can export than the large several-fold thrust of gas-liquid damping cylinder in the utility model lowering or hoisting gear, thrust is steady, has increased the processing characteristics of drilling machine.When workpiece was very long, during boring, stability was bad, needs two hydraulic cylinders are installed, and balanced valve is installed in hydraulic system, to increase stability.
