Description
Technical field
The present invention relates to a kind of frock clamp, especially relate to a kind of clamp for cutting for building hoist column port Cutting Process; The invention still further relates to the cutting working method of building hoist column port.
Background technology
Building hoist is again construction elevator for building, is the manned cargo-carrying construction machinery that often uses in the building, because its unique body structure makes it take not only comfortable but also safety, building hoist normally cooperates tower crane to use on-site.The frame of building hoist is made of several standard knots, along with development of construction, the maximum antenna height of building hoist has reached 150 meters, adopt the scale-up version standard knot can increase to 250 meters, therefore more and more higher to the requirement on machining accuracy of standard knot, the column connectivity port machining accuracy of standard knot is even more important, with performance and the raising installation effectiveness that ensures building hoist.
At present, the column connectivity port processing of building hoist is still carried out at lathe, the processing of column connectivity port is the hilted broadsword cutting on the lathe, elongated column is in working angles, it is subjected to radial cutting force to affect easy flexural deformation, and produce vibration, machining accuracy is not high, is difficult to satisfy the Performance and quality requirement of high-quality building hoist.
Summary of the invention
In order to overcome the deficiency of existing building hoist column port Machining Technology for Cutting.The present invention proposes a kind of building hoist column port clamp for cutting, be intended to solve the not high technical problem of prior art central post port machining precision.
In order to solve the problems of the technologies described above, the technical scheme of building hoist column port clamp for cutting provided by the invention is as follows: a kind of building hoist column port clamp for cutting, be installed on the guide rail of the body of lathe bed, have the clamping fixture seat that the bottom cooperates with guide ways on lathe bed; The pipe spreader that is fixedly connected with described clamping fixture seat; The outer ring cooperates clutch shaft bearing and the second bearing that is installed on described pipe spreader both ends; Cooperate the hollow rotating shaft that is installed in described clutch shaft bearing and the second bearing inner race; The ring flange that is fixedly connected with described hollow rotating shaft one end; With the self-centering chuck that described ring flange removably connects, after described clamping fixture seat cooperates on the guide rail that is installed in the body of lathe bed, the chuck concentric of described self-centering chuck and lathe.
Further, described building hoist column port clamp for cutting also has the first end cap and the second end cap that are detachably connected on described pipe spreader two ends.
Further, the self-centering chuck of described building hoist column port clamp for cutting is three-jaw or four paws self-centering chuck.
Further, described building hoist column port clamp for cutting also has be connected on the hollow rotating shaft hold-down nut that stops hollow rotating shaft to slide in described clutch shaft bearing and the second bearing.
The technical scheme of the cutting working method of building hoist column port provided by the invention is as follows: a kind of processing method of building hoist column port, use the described clamp for cutting of aforementioned arbitrary technical scheme, comprise that the following step poly-: described clamp for cutting is installed on the guide ways on lathe bed; After described building hoist column passed from the hollow rotating shaft of clamp for cutting, an end gripped with the chuck of lathe, and nearly tool for cutting machining position grips with the self-centering chuck of clamp for cutting; Port to described column carries out machining.
Above-mentioned improvement project can be implemented alone or in combination in the situation of not conflicting.
Self-centering chuck utilizes screw, by the screw on the disk body seam end face, chuck is fastened on the lathe flange, spanner is inserted in arbitrary gear square hole, and during rotating spanner, pinion drives parcel and rotates, by the rotation of parcel end-face helical, the drive claw becomes simultaneously into or disperses.But the claw radial concentric of self-centering chuck moves and makes the workpiece self-centering, and its structure belongs to known technology in the lathe technical field.
The present invention has following beneficial effect: during work, the lathe grinding clamp for machining is installed on the guide ways on lathe bed, after described building hoist column passed from the hollow rotating shaft of clamp for cutting, one end grips with the chuck of lathe, nearly tool for cutting machining position grips with the self-centering chuck of clamp for cutting, because the chuck of lathe and the self-centering chuck of clamp for cutting are on the same axle center, the column that adds the building hoist in man-hour has two fixing points, when being affected by radial cutting force, it is difficult for flexural deformation, and be difficult for producing vibration, improved machining accuracy, thereby solved in the prior art the not high technical problem of building hoist column machining precision.
Description of drawings
Accompanying drawing is used to provide a further understanding of the present invention, consists of the application's a part, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of embodiment clamp for cutting;
Fig. 2 is that the embodiment clamp for cutting uses view.
The specific embodiment
Building hoist column port clamp for cutting has on the guide rail that is installed in the body of lathe bed as shown in Figure 1, the clamping fixture seat 10 that the bottom cooperates with guide ways on lathe bed, the bottom of clamping fixture seat 10 is provided with groove, cooperate with V-way and the rectangular guideway of the body of lathe bed, accurate location when being convenient to install, pipe spreader 5 is fixedly connected with the top of described clamping fixture seat 10, the both ends of pipe spreader 5 have bearing block, the outer ring of clutch shaft bearing 4 and the second bearing 6 cooperates respectively in the bearing block that is installed in described pipe spreader 5 both ends, hollow rotating shaft 7 cooperations are installed in the inner ring of described clutch shaft bearing 4 and the second bearing 6, ring flange 2 is fixedly connected with the first end of described hollow rotating shaft 7, the first end cap 3 and the second end cap 9 removably are connected to the two ends of described pipe spreader 5 by bolt, three-jaw self-centering chuck 1 and described ring flange 2 removably are fixed together by bolt, after clamping fixture seat 10 cooperates on the V-way that is installed in the body of lathe bed and the rectangular guideway, the chuck concentric of described three-jaw self-centering chuck 1 and lathe.
