Abstract

The utility model relates to a reaming machine and is characterized in the coaxial installation of a motor, a one-stage speed reducer and a two-stage speed reducer. Wherein, the two-stage speed reducer is suspended by a steel wire inhaul cable. The output shaft of the two-stage speed reducer is connected with a rimer holder coupling flange through an universal shaft coupler. In addition, one end of the rimer holder is positioned on the cutter holder coupling flange and the other end is provided with a sleeve-type rimer. The transmission shaft center of the motor shares the same horizontal line with the rimer holder centerline and the output shaft center. A shackle is positioned on the two-stage speed reducer. In addition, the motor and the speed reducer are suspended and balanced by the steel wire inhaul cable through the shackle. The steel wire inhaul cable 3 shapes an angle towards the motor and the barycenter line of the speed reducer. The large-aperture reaming machine provides larger reaming scope and facilitates onsite positioning. The whole machine is suspended and positioned by the flexible steel wire to reduce time on machine positioning and slow down rimer holder rotation. The reaming machine is fixed during reaming, realizes polished pore walls and conforms to relevant precision requirements.

Description

The on-the-spot broach(ing) machine in large aperture

Technical field:

The utility model relates to broach(ing) machine, particularly the on-the-spot broach(ing) machine of main equipment maintenance.

Background technology:

In industries such as cement, metallurgy, generating, oil, chemical industry, main equipment has progressively been eliminated mini-plant, and when equipment rebuilding, some big and difficult problems are met by regular meeting.When changing high-power mill trunnion as the cement plant, brill, fraising, assembling interference bolt need be joined in 24 (φ 65mm) holes on the flange, could guarantee that quill shaft combines with grinding machine end face flange rigidity, if do not assemble the equipment fault that then is prone to bolt pine, bolt fracture on request.How could guarantee that king-bolt hole on the flange is joined brill, fraising everything goes well with your work in maintenance sites implements, and instrument is crucial.Bore to be used as power with magnetic force now and be transformed into the bore hole form scene of having solved and join the brill problem, and the on-the-spot fraising in large aperture is a stubborn problem always that hand reamer is during greater than φ 35mm, the people just is difficult to pull; And install at traditional chucking reamer scene, the location all is a difficult problem.

Summary of the invention:

The purpose of this utility model provides a kind ofly can carry out device on-the-spot efficient, quick fraising to heavy mechanical equipment.

In order to achieve the above object, the utility model is by the following technical solutions: the large aperture broach(ing) machine comprises motor, first class reducer, 2-level reducer, knife bar and reamer, motor, one-level and 2-level reducer three adopt coaxial manner to install, 2-level reducer is suspended by the steel wire rope drag-line, the output shaft of 2-level reducer is connected with the knife bar connecting flange by Hooks coupling universal coupling, knife bar one end is installed in the knife bar connecting flange, and the knife bar other end is installed the shell type chunking reamer; The power transmission shaft axle center of motor coexists with knife bar center line and output shaft axle center on the horizontal line; 2-level reducer is provided with large aperture broach(ing) machine deadweight hanger and moment of torsion transmits hanger; Motor and reductor transmit hanger by deadweight hanger and moment of torsion and hang and balance with the steel cable drag-line; Steel cable drag-line 3 is angled to motor direction and reductor center of gravity line, produces a horizontal component forward, in order to feed.

Adopt the large aperture broach(ing) machine of above technical scheme to have the following advantages: the fraising scope is big, can articulation from scene, 35-120 aperture, but get final product as the bigger hole expanded motor of need articulation and the power of reductor.On-the-spot location is convenient and swift, whole fuselage is by steel wire rope flexible suspension location, chain block can be adjusted the length of steel wire rope at any time, fuselage is positioned with the reliable Hooks coupling universal coupling of error and revises, guarantee knife bar parallel feed (but also vertical feed operation), reduced the time of the on-the-spot location of fuselage; The knife bar rotating speed is easy to execute-in-place slowly, and complete machine is not swung during fraising, and it is highly polished to cut with scissors out hole wall, meets the quality of fit requirement.

Description of drawings:

Fig. 1 shows schematic diagram for the utility model master looks;

Fig. 2 is that the A of the utility model Fig. 1 is to schematic diagram.

The specific embodiment:

Below in conjunction with accompanying drawing, the utility model will be further described:

As shown in Figure 1 and Figure 2, the large aperture broach(ing) machine comprises motor 1, first class reducer 2,2-level reducer 7, knife bar 6 and reamer 9.Motor 1, first class reducer 2 and 2-level reducer 7 adopt coaxial installation, and two reductors are cycloid pin decelerator, and 2-level reducer 7 is suspended by steel wire rope drag-line 3; The output shaft 4 of 2-level reducer 7 is connected with knife bar connecting flange 5 by Hooks coupling universal coupling 8, and knife bar 6 one ends are installed in knife bar connecting flange 5, and knife bar 6 other ends are installed shell type chunking reamer 9.The power transmission shaft axle center of motor 1 coexists with knife bar 6 center lines and output shaft 4 axle center on the horizontal line.2-level reducer 7 is provided with the deadweight hanger and moment of torsion transmits hanger 10; Motor 1 and

reductor

2 and 7 transmit hanger 10 by deadweight hanger and moment of torsion and hang and balance with steel cable drag-

line

3,11,12 respectively.Steel cable drag-line 3 is angled to motor 1 direction and reductor center of gravity line, produces a horizontal component forward, in order to feed.

Adopt above technology, its principle is to make up with the form of connecting with two cycloid pin type reductors with a 2.2KW (4 grades) motor, form double reduction, second level speed reducer output shaft rotating speed is that every clock 1.8-3 changes, speed reducer output shaft connects Hooks coupling universal coupling, link by flange and knife bar again, assemble shell machine reamer on the knife bar head; Hanger is arranged fixedly for reeve usefulness on the reductor, the on-the-spot suspension centre that hangs joins with steel wire rope on chain block and the hanger, the available chain block adjustment of the broach(ing) machine height of slinging, and the hoist cable certain angle that should turn forward makes broach(ing) machine produce a feed component forward.On-the-spot in the past fraising be the self-control machine with the fraising device, at the scene sliding rail special need be installed, slide rail with required highly by the fraising depth of parallelism, the on-the-spot location difficulty of fraising device, time are long, and easily hinge is inclined to one side in the hole, the reamer cutting edge easily collapses piece.The on-the-spot broach(ing) machine suspension type localization method in this large aperture utilizes Hooks coupling universal coupling to adjust deviations, makes on-the-spot fraising operation become convenient, fast, for a lot of quality time are won in field maintenance.
