Abstract

A main limb contraposition drill for construction tower machinery equipment is characterized in that it comprises a body, a slide table, drill heads, and a hydraulic cylinder, wherein, the body (1) is horizontal, a left (5) and a right (2) slide plates are installed at the two ends of the slide table on the body (1), a left (7) and a right (4) drill heads are respectively fixed on the left (5) and the right (2) slide plate. The utility model employs a contraposition slide table and uses the straight line accuracy of the slide table as the fundament to guarantee the same axial degree of the two cores of the main limb. The utility model is capable of processing high accuracy and large length products. By the hydraulic continuous speed regulation feeding, the utility model fulfills the various processing requirements. In addition, the utility model controlled by a PLC programmable controller achieves the semi-automation and the work efficiency increasing. Moreover, the utility model has the advantages of simple structure and convenient operation, installation and maintain.

Description

Main limb is to rig

Technical field

Main limb belongs to tower mechanism manufacturing apparatus for building to rig.

Background technology

The fuselage of tower machine for building is to be assembled by standard knot.Each standard knot is by four main limbs, the smooth butt joint of standard knot, and in allowed limits whether the foozle that is decided by screw on the main limb and pin-and-hole.

Generally in 2.5～3 meters scopes, the axiality of two stomidiums requires in Φ 0.1 length of main limb, i.e. 6～7 class precisions.So high precision is processed relatively difficulty on the universal machine tools that specialized factory produces, and efficient is low, cost is high, and its processing length exceeds the range of work of general universal machine tools.

The utility model content

The technical problems to be solved in the utility model is: overcome the problem that prior art exists, design a kind of simple in structure, can machining high-precision, the main limb of big length is to rig.

The technical scheme that its technical problem that solves the utility model adopts is: this main limb is to rig, it is characterized in that: comprise lathe bed body, slide unit, rig head, hydraulic cylinder, lathe bed body are horizontal, the slide unit two ends of lathe bed body top are provided with opposed left and right sides slide plate, and left and right sides rig head is separately fixed at the top of left and right sides slide plate.

Left and right sides hydraulic cylinder is installed in lathe bed body two ends respectively, and the piston rod of left and right sides hydraulic cylinder is connected with left and right sides slide plate respectively.

Left and right sides rig head comprises rig headstock, motor, decelerator, drill point.

Operation principle:,, on lathe bed body slide unit, adopt opposed slide unit rig head mould formula to guarantee main limb two ends two hole axialities as the basis that guarantees main limb two hole axialities with the straight line precision of slide unit fuselage.

Compared with prior art, the beneficial effect that the utility model had is: this lathe bed body adopts the pattern of opposed slide unit, with the straight line precision of slide unit fuselage, and as the basis that guarantees main limb two hole axialities, can machining high-precision, the product of big length.Select the acorde bur head for use, save manufacturing cost, shorten the manufacturing cycle.Adopt the hydraulic stepless speed regulating feeding, to adapt to different processing requests.Adopt the PLC Controlled by Programmable Controller, the operation that realizes semi-automation improves work efficiency.Have advantages such as simple in structure, that the operation installation and maintenance are convenient simultaneously.

The specific embodiment

Below in conjunction with accompanying drawing 1-4 main limb of the present utility model is described further rig:

As shown in Figure 1: main limb is made up of lathe bed body 1, right slide plate 2, right hydraulic cylinder 3, right rig head 4, left skateboard 5, left hydraulic cylinder 6, left rig head 7 rig.Lathe bed body 1 is horizontal, and the slide unit two ends on the lathe bed body 1 are provided with opposed left and right sides slide plate 5,2, and left and right sides slide plate 5,2 is placed on the slide unit.Left and right sides rig head 7,4 is separately fixed at the top of left and right sides slide plate 5,2.Left and right sides hydraulic cylinder 6,3 is installed in lathe bed body 1 two ends respectively, and the piston rod of left and right sides hydraulic cylinder 6,3 is connected with left and right sides slide plate 5,2 respectively.Slide unit above lathe bed 1, with lathe bed 1 be one.Left and right sides rig head 7,4 comprises rig headstock, motor, decelerator, drill point 8, and motor links to each other with decelerator, decelerator links to each other with drill point 8 with the rig headstock.

As shown in Figure 2: control panel 9, rig head motor 10, Hydraulic Station 11, position switch K, PLC Programmable Logic Controller.

The course of work: this machine adopts the hydraulic stepless speed regulating feeding, and PLC programmable controller program control operation can be taked opposed while feeding to main limb two ends, also can take respectively to main limb right-hand member or the independent feeding of left end.

Preparation is adjusted left and right sides rig head and is made it coaxial, adjusts position sensor 1XK-6XK to requiring the position, and suitable drill bit is installed on the rig head drill point of the left and right sides, and workpiece master limb is fixed between the rig head of the lathe bed body left and right sides.

Shown in Fig. 2-4:

To the independent feeding boring procedure of main limb left end, behind select operating mode " left side " on the guidance panel 9, click the Auto button, left rig head motor rotates, driving drill bit by reductor rotates, left skateboard is pressed operation schematic diagram operation among Fig. 3, and slide plate is advanced fast by original position 4XK earlier, and drill bit advances drilling behind the arrival 5XK, enter the time-delay stage after arriving desired depth 6XK, when delay time arrives, then slide plate drives left rig head and returns original position 4XK fast, and slide plate is out of service finishes a drilling.

To the independent feeding boring procedure of main limb right-hand member, behind select operating mode " right side " on the guidance panel 9, click the Auto button, right rig head motor rotates, driving drill bit by reductor rotates, right slide plate is pressed operation schematic diagram operation among Fig. 4, and slide plate is advanced fast by original position 1XK earlier, and drill bit advances drilling behind the arrival 2XK, enter the time-delay stage after arriving desired depth 3XK, when delay time arrives, then slide plate drives right rig head and returns original position 1XK fast, and slide plate is out of service finishes a drilling.

To main limb two ends feeding simultaneously boring procedure, behind select operating mode " simultaneously " on the guidance panel 9, click the Auto button, left and right sides rig head motor rotates, driving left and right sides drill bit by reductor rotates, left and right sides slide plate moves simultaneously by operation schematic diagram among Fig. 3-4, left and right sides slide plate is earlier by original position 4XK, 1XK advances fast, arrive 5XK, drill bit advances drilling behind the 2XK, arrive desired depth 6XK, enter the time-delay stage behind the 3XK, when delay time arrives, then left and right sides slide plate drives left and right sides rig head and returns original position 4XK fast, 1XK, left and right sides slide plate is out of service finishes a drilling.
