Abstract
The invention discloses a drilling machine tool dedicated for a truck side frame, belonging to the technical field of railway truck machining. The drilling machine tool comprises a substrate, a side frame locating base, a clamping bracket, a stand column drilling head and a stand column drilling head guide rail, wherein one side of the substrate is provided with two symmetrical stop key drilling heads and stop key drilling head guide rails. According to the drilling machine tool, machining working procedures are reduced, equipment amount is reduced, and production cost is lowered; stop key drilling quality is improved; times for hoisting and clamping are reduced, manpower amount is reduced, worker labor intensity is lightened, and manpower cost is lowered; working procedures and product amounts are reduced, the flat area of the machining technology is reduced, the product working procedure cycle is shortened, and production efficiency is improved; and the drilling machine tool is used for machining the truck bogie side frame of 70 tons and above.
Description
Affiliated technical field
The present invention relates to the railway freight-car manufacturing equipment, especially the machining equipment of bogie side frame belongs to the railway freight-car machine and adds technical field.
Background technology
At present, the technology that the boring of lorry three-major-items cast steel truck side frame processing is generally adopted is: special drill press processing is adopted in the hole in the bogie side frame central authorities square frame, and bogie side frame stands up or crouches to put and is installed; General radial drilling machine processing is adopted in the block key hole at bogie side frame two ends, and bogie side frame stands up and is installed; Therefore boring is processed palpus two complete equipments, could be accomplished through two procedures, and production efficiency is low, and processing cost is high.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing bogie side frame boring processing, the present invention provides a kind of special jewel hole machine tool.
The technical solution adopted for the present invention to solve the technical problems is: lorry bogie side frame special jewel hole machine tool comprises pedestal, bogie side frame positioning seat, the support that is installed, column drilling head and column drilling head guide rail; Pedestal one side is provided with two the block key drilling heads and the block key drilling head guide rail of symmetry.
The invention has the beneficial effects as follows, reduce manufacturing procedure, reduce number of devices, reduced production cost; Improve the block key drilling quality; Reduce the lifting and the number of times that is installed, reduce artificial quantity, alleviate labor strength, reduced cost of labor; Reduce the operation goods in process inventory, dwindle the processing technology area of plane, shortened the production process cycle, improved production efficiency.Be used for the machined of 70 tons and higher level roller bearing adapter stabilizer bar bogie side frame.
Description of drawings
Fig. 1 is a general plane structural representation of the present invention;
Fig. 2 is user mode (bogie side frame crouches and the puts clamping) floor map of Fig. 1.
Parts and numbering among the figure:
1-block key drilling head guide rail, 2-block key drilling head, 3-column drilling head guide rail, 4-column drilling head, the 5-support that is installed, 6-pedestal, 7-bogie side frame positioning seat, 8-workpiece anchor point, 9-clamping lever, 10-workpiece centrally-located point, 11-bogie side frame.
The specific embodiment
Below in conjunction with embodiment the present invention is further specified.
Referring to Fig. 1,2, lorry bogie side frame special jewel hole machine tool comprises pedestal 6, bogie side frame positioning seat 7, the support 5 that is installed, column drilling head 4 and column drilling head guide rail 3; Pedestal 6 one sides are provided with two the block key drilling heads 2 and the block key drilling head guide rail 1 of symmetry.
Adopt combined drill box formula, the profile layout is three frame type structures, is made up of three drilling head casees.
Column drilling head guide rail 3 constitutes central square frame rig with column drilling head 4; Block key drilling head guide rail 1 constitutes the block key rig with block key drilling head 2; A drilling head case is used in central authorities' square frame boring, and a drilling head case is respectively used in two block key borings; Each drilling head case all has guide rail independently, and two block key drilling head guide rails 1 are parallel to each other, and perpendicular with column drilling head guide rail 3.
Column drilling head guide rail 3 is can the left and right sides two-way to be moved, by the three phase electric machine of a 3.5KW as power, through belt pulley, gear, Worm wheel transmission mechanism, leading screw and nut transmission mechanism are realized the side-to-side movement and boring action of column drilling head 4; The processing of bogie side frame square frame left and right pillar face is accomplished in the both direction feeding in the left and right sides respectively.And the processing in block key hole is accomplished in the feeding of advancing of two block key hole drilling heads 2.
Two block key drilling heads 2 respectively have independent power motor and feeding motor; The feeding motor drives the drilling head case through reduction box mechanism and screw-nut body and moves forward and backward along block key drilling head guide rail 1; Drive drilling head case main shaft and rotate, realize the drilling action of block key drilling head 2.
Crouch and be placed on the support 5 that is installed of lathe in bogie side frame 11 planes, column drilling head 4 links with block key drilling head 2 and moves, and when boring central square frame column face, carries out the Drilling Operations in two block key holes.
Bogie side frame 11 crouches to put and holes when being installed; Utilize bogie side frame positioning seat 7 as bogie side frame location located lateral benchmark; Utilize bogie side frame adapter drawing strickle guide side as bogie side frame longitudinal register benchmark, reservoir drives the lever clamping work pieces, has solved bogie side frame and has stood up the problem of rocking of boring in the process of block key hole; Improve block key hole surface quality and positional precision, thereby improved the block key drilling quality.
Process:
Adopt this machine tooling bogie side frame hole, at first carry out the lifting card of bogie side frame, press the position of workpiece anchor point 8 and workpiece centrally-located point 10, bogie side frame 11 is crouched to be put on the support 5 that is installed at equipment middle part, utilizes reservoir to drive clamping lever 9 clamping work pieces (see figure 2)s.
Bore central square frame column face: start column drilling head 4, accomplish the processing of an end column face, the operation reversing handle is accomplished the processing of other end column face, and column drilling head 4 is return the centre position.
Bore two block key holes: when boring central square frame one end column face, these end block key drilling head 2 interlocks start, and accomplish the processing of block key hole, return then.
Start reservoir, unclamp bogie side frame, it is hung lathe, accomplish bogie side frame boring process.
