Abstract
The utility model relates to a device for adjusting a center rest of a heavy-duty horizontal lathe. The device is characterized in that a Y-shaped supporting rack and a base thereof are arranged on alathe guide tack, lateral supporting heads are arranged on the two sides of the supporting rack, a guide block and a main supporting head are arranged at the bottom of the supporting rack, a supporting plate and an oil cylinder are arranged at the lower end of the guide block, an upper ram with an inclined plane is arranged on each side below the supporting plate, two planar lower rams are correspondingly arranged on a supporting rack base, an adjusting block with a matched inclined plane is arranged between the upper ram and the lower ram on each side, a driving screw connected with lateral adjusting threads is arranged on the side surface of the supporting rack, a link rod is hinged on the side surface of each adjusting block, a middle rod is hinged between the two link rods on the two sides, and a rotating shaft arranged between the middle part of the middle rod and the supporting rack. The device solves the problems of a major diameter workpiece mounting center rest, so that the center rest can ensure that a lathe and a tool rest can smoothly pass through under limit space. The device also has the advantages of simple structure, easy manufacturing, and convenient operation.
Description
Technical field
The utility model relates to a kind of lathe centre frame, especially a kind of heavy sleeping carriage centre frame adjusting device.
Background technology
Heavy sleeping carriage is a kind of important process equipment in the machine industry, is mainly used in the axle part that processing various axial workpieces, particularly weight are big, diameter is thick, required precision is high.When the various major axis part of processing, the auxiliary equipment centre frame is installed on the lathe guide rail, can improve rigidity and machining accuracy, the reduction surface roughness of part to be processed effectively and increases work efficiency.Present known centre frame structure is: Y shape bearing support and base thereof are installed on the lathe guide rail, in the bearing support both sides side supporting member is installed, in the bearing support bottom guide pad and main supporting member are installed, the adjusting device that bevel gear and threaded screw rod match is installed in the guide pad lower end, and wherein, bevel gear partly belongs to jacking mechanism, it mainly is the climbing power that the power of motor is converted into the jack-up workpiece, after jack-up, partly lock by threaded screw rod, to determine its position.This adjustment, retaining mechanism complexity, institute takes up space bigger.But, when machine tool chief axis is certain to guide pass distance, a side is subjected to the slip crate restriction and diameter of work is bigger situation, will cause the height of centre frame to be very limited, thereby known centre frame can't use when the bigger major axis part of processing diameter, cause processing difficulties, influence the machining accuracy and the machined surface quality of workpiece, increased production cost.
Summary of the invention
The utility model provides a kind of heavy sleeping carriage centre frame adjusting device that is suitable for processing the big workpiece of diameter for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of heavy sleeping carriage centre frame adjusting device, comprise the Y shape bearing support and the base thereof that are installed on the lathe guide rail, be installed in the side supporting member of bearing support both sides, be installed in the guide pad and the main supporting member of bearing support bottom, be installed in the support plate and the oil cylinder of guide pad lower end, and the adjusting device of main supporting member, described adjusting device is the upper ram that both sides are equipped with the band inclined-plane below support plate, in correspondence on the bearing support base ram under two planes is installed, the adjustment piece on band coupling inclined-plane is installed between the upper ram of both sides and following ram, the drive screw that is threaded with side adjustment piece is installed in the bearing support side, adjust the piece side two and be hinged with gangbar respectively, be hinged with intermediate bar between the both sides interlock rod end, between the middle part of intermediate bar and the bearing support rotating shaft be installed.
Advantage and the good effect that the utlity model has are;
Because both sides are equipped with the ram on band inclined-plane and adjust piece below main retrieving head support plate, be equipped with between the two adjustment pieces and be hinged with gangbar and intermediate bar, and be installed in the bearing support side and drive two and adjust the screw rod that pieces relatively move, pass through rotating screw bolt, make two to adjust same moved further about pieces (adjusting hinge on the piece drives intermediate bar by gangbar and rotate around the axis, power is passed to the adjustment piece of opposite side, make its move left and right), the realization both sides are adjusted height simultaneously, have guaranteed the uniformity of adjustment amount; Solved the problem of large-diameter workpiece mounting center frame, made it can be under the condition of limited of space, guaranteed to pass through smoothly adding the man-hour backrest; In addition the utility model also have simple in structure, be easy to make, easy to operate advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, bearing support; 2, base; 3, oil cylinder; 4, following ram; 5, adjust piece; 6, screw rod; 7, upper ram; 8, main supporting member; 9, side supporting member; 10, axle part; 11, side supporting member; 12, guide pad; 13, spherical aligning piece; 14, support plate; 15, upper ram; 16, adjust piece; 17, following ram; 18, gangbar; 19, intermediate bar; 20, gangbar; 21, rotating shaft.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, Fig. 2, bearing support 1 is Y-shaped, and this bearing support is installed on the lathe guide rail.The bottom of bearing support is equipped with base 2, side supporting member 9,11 is installed in the bearing support both sides, in the bearing support bottom guide pad 12 and main supporting member 8 are installed, spherical aligning piece 13 is installed between guide pad and the main supporting member, support plate 14 and oil cylinder 3 are installed in the guide pad lower end.Both sides are equipped with the upper ram 7,15 on band inclined-plane below support plate, in correspondence on the bearing support base ram 4,17 under two planes is installed, the adjustment piece 5,16 on band coupling inclined-plane is installed between the upper ram of both sides and following ram, the drive screw 6 that is threaded with side adjustment piece 5 is installed in the bearing support side, adjust the piece side two and be hinged with gangbar 18,20 respectively, be hinged with intermediate bar 19 between the both sides interlock rod end, rotating shaft 21 is installed between the middle part of intermediate bar and the bearing support.Like this, by rotating screw bolt, make two to adjust same moved further about pieces (adjusting hinge on the piece drives intermediate bar by gangbar and rotate around the axis, power is passed to the adjustment piece of opposite side, make its move left and right), the realization both sides are adjusted height simultaneously, have guaranteed the uniformity of adjustment amount; Solved the problem of large-diameter workpiece mounting center frame, made it can be under the condition of limited of space, guaranteed to pass through smoothly adding the man-hour backrest; In addition the utility model also have simple in structure, be easy to make, easy to operate advantage
