Abstract
The utility model discloses a large double-suction pump shaft hole boring processing device which comprises a power unit (1), a boring bar (5) and a workbench (8) used to hold a large double-suction pump (9); the power unit (1) corresponds to the workbench (8) and is arranged on a guide rail (2) in a sliding way and connected with a longitudinal feeding mechanism (3) in the form of transmission; the main shaft of the power unit (1) is connected with the boring bar (5) by a universal joint (4); the boring bar (5) is provided with bearings (6,7) capable of sliding in the radial direction. The longitudinal feeding mechanism (3) is provided with the functions of automatic tool advancing, forward tool advancing, backward tool advancing and tool retracting. The universal joint (4) is flexibly connected which is different from the rigid connection of tapered holes of the main shaft of a common boring lathe. The boring bar (5) is positioned by the bearings (6,7) which can slid in the radial direction, thereby saving the tail stock of the common boring lathe and achieving the effect of a self-positioning boring. The large double-suction pump shaft hole boring processing device has the advantages of simple structure, low investment, less space taken, flexible and convenient operation, reliable processing quality, very high practical value and promotion value.
Description
Technical field
The utility model relates to a kind of boring processing unit (plant), particularly relates to a kind of processing unit (plant) of the machining large double entry pump axis hole boring of using when lacking large-scale general or special boring mill.
Background technology
To the boring of bore greater than the large-scale double entry pump axis hole more than the Φ 1000mm, traditional diamond-making technique is the horizontal boring machine or the special plane of the high large-scale general that allows of shopping center, normally boring bar taper shank and boring spindle hole are rigidly connected, the boring bar terminal is by the tailstock supporting, and boring bar and cutter are realized feeding by the longitudinal feed mechanism of boring machine.The shortcoming of traditional diamond-making technique is: 1, want to cost an arm and a leg more than the above large-scale general boring machine T6118 of configuration center height＞1800mm.2, floor space is big, about 25m
2About.3,, need at least two or more operation big because of equipment.4, need the corresponding more frock of configuration, input cost is bigger.5,,, proofread and correct trouble so that workpiece centre must guarantee is consistent with the boring machine center because of being the boring bar that is rigidly connected.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple to operate, and precision is accurate, and main is the large-scale double entry pump axis hole boring processing unit (plant) of reducing investment outlay.
In order to solve the problems of the technologies described above, the large-scale double entry pump axis hole boring processing unit (plant) that the utility model provides, comprise unit head, boring bar and lay the workbench of the large-scale double suction pump housing, described unit head is corresponding with described workbench and be slidingly mounted on the guide rail and with longitudinal feed mechanism and be in transmission connection, the main shaft of described unit head is connected with described boring bar by universal joint, on described boring bar bush(ing) bearing is installed.
Adopt the large-scale double entry pump axis hole boring processing unit (plant) of technique scheme, unit head has high accuracy boring function, and longitudinal feed mechanism has from feed, front and back feed and withdrawing function.Universal joint is rigidly connected different for flexibly connecting with common boring spindle taper hole.Boring bar is located by bush(ing) bearing, saves the tailstock of common boring machine, reaches the purpose of self poisoning boring self.Compared with prior art, have following advantage:
1, investment little, only need the common boring unit head of a cover, power is about 12 kilowatts, feed motion is simple, only needs vertically that advance and retreat get final product, and does not need the purchasing price costliness, sinuous universal machine tools;
2, owing to adopt universal joint to flexibly connect, boring bar does not need the tailstock supporting, and the adjustment of opening face and boring machine unit head pivot in the workpiece is not needed strict centering, and position error can allow 15～20mm;
3, easy and simple to handle, quick, accurate positioning.
In sum, the utility model is simple in structure, invest cheap (only for purchase common apparatus about 1/15), occupied ground few (be about common apparatus about 1/4), operation is nimble, crudy is reliable.
Description of drawings
Accompanying drawing is the utility model device schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to accompanying drawing, unit head 1 and workbench 8 are corresponding and be slidingly mounted on the guide rail 2 and with longitudinal feed mechanism 3 and be in transmission connection, the main shaft of unit head 1 is connected with boring bar 5 by universal joint 4, and first bush(ing) bearing 6 and second bush(ing) bearing 7 are installed on boring bar 5.
Referring to accompanying drawing, the large-scale double suction pump housing 9 is placed on the workbench 8, and the unit head 1 with boring function passes through longitudinal feed mechanism 3 front and back feed and withdrawings on guide rail 2, and the main shaft of boring unit head 1 is connected with boring bar 5 by universal joint 4.
When boring machining large double entry pump stuffing hole 10, the face of at first opening in the processing of bearing saddle bore 11 is installed first bush(ing) bearing 6, boring bar 5 is by first bush(ing) bearing, 6 location, boring stuffing hole 10, at stuffing hole 10 second bush(ing) bearing 7 is installed then, boring bar 5 is by second bush(ing) bearing, 7 location, and boring double suction sealing annular distance 12 and two end axles bearing hole 11 put in place.
The utility model is simple in structure, invests that cheap, occupied ground reduces, operation is nimble, crudy is reliable, has very strong practical value and promotional value.
Personnel in the present technique field should be realized that, the foregoing description is not with this novel qualification of opposing, as long as in this novel connotation scope, any the foregoing description technique variation, flexible program are not all exceeded protection domain of the present utility model.
Claims (1)
1, a kind of large-scale double entry pump axis hole boring processing unit (plant), comprise unit head (1), boring bar (5) and lay the workbench (8) of the large-scale double suction pump housing (9), it is characterized in that: described unit head (1) is corresponding with described workbench (8) and be slidingly mounted on that guide rail (2) is gone up and be in transmission connection with longitudinal feed mechanism (3), the main shaft of described unit head (1) is connected with described boring bar (5) by universal joint (4), and bush(ing) bearing (6,7) is installed on described boring bar (5).
