Abstract
The utility model discloses a turning clamp with an adjustable inner diameter. The turning clamp with the adjustable inner diameter comprises four clamping plates and four pipes, each of the four clamping plates is a quarter of an arc plate, the four clamping plates form a whole circle, each of the pipes is connected with an outer arc of each of the clamping plates in a welding mode, two ends of each of the clamping plates are respectively provided with a convex lug, adjacent clamping plates are connected through bolts and nuts, the bolts and the nuts pass through the convex lug, and the four clamping plates form an end-to-end integration. When the turning clamp with adjustable inner diameter is used, firstly, the four clamping plates are assembled through the bolts and sleeved on a shaft neck of a rotor of large rotating machinery equipment, and then, the size of the inner diameter of each of the clamping plates is changed through adjusting the nuts, and thus the shaft neck of the rotor is clamped tightly, at last, the pipes are inserted into sleeve tubes, and thus turning can be conducted effortlessly. According to the turning clamp with the adjustable inner diameter, the problem of turning when a unit with a shaft neck in a certain size range is centered is resolved, convenience and swiftness are achieved, the efficiency of installation and maintenance is improved, and production cost is reduced.
Description
Technical field
The utility model relates to large rotating machinery and decides core jiggering fixture.
Background technology
In Diagnosing System for Oil Pump installation and repairing process, initiatively need to decide core between machine and driven machine, both center lines are overlapped, if both center lines have deviation, use the jiggering fixture to carry out synchronous jiggering to active machine and driven machine rotor with regard to needs, coordinate the centering instrument to complete measurement, adjust, making initiatively, machine overlaps with the center line of driven machine.But, non-adjustable or the adjustable extent＜10mm of the internal diameter of existing jiggering fixture, so usually because axle journal and the existing jiggering grip size of active machine and driven machine rotor do not match and will again make fixture, both incur loss through delay the installation and repairing time, improved again production cost.
Summary of the invention
Problem to be solved in the utility model is to provide the adjustable jiggering fixture of a kind of internal diameter, the jiggering problem that this fixture can solve the unit of axle journal in the certain size scope when deciding core, it is convenient and swift, has improved installation and repairing efficient, has also reduced production cost.
The jiggering fixture that a kind of internal diameter of the utility model is adjustable is characterized in that: it comprises four clamping plates, four pipes, and every clamping plate is quadrant arc plate, and four clamping plates form a full circle; Be welded with a pipe on the external arc of every clamping plate; The circular arc two ends of every clamping plate are provided with a lug, are connected by bolt, the nut that passes lug between adjacent clamping plate, and four clamping plates form an integral body from beginning to end.
When using this fixture, first four clamping plates are assembled by bolt, be enclosed within on the axle journal of large rotating machinery equipment rotor; Then change the size of clamping plate internal diameter by adjusting nut, thereby clamp the axle journal of rotor; Plug at last sleeve pipe on pipe, can carry out effortlessly jiggering.
Adjusting range≤the 40mm of the utility model internal diameter namely utilizes the fixture just can be to internal diameter for D～(D+40) mm(D is the diameter of clamping plate) axle journal of rotor in scope clamps, and both saved the installation and repairing time, reduced again production cost.
Description of drawings
Fig. 1 is the schematic diagram of this novel discs vehicle clamper.
The specific embodiment
As can be seen from Figure 1, the jiggering fixture that a kind of internal diameter of the utility model is adjustable, it comprises four clamping plates 1, four pipes 2, and every clamping plate 1 is quadrant arc plate, and four clamping plates 1 form a full circle; Be welded with a pipe 2 on the external arc of every clamping plate 1; The circular arc two ends of every clamping plate 1 are provided with a lug 3, are connected by bolt 4, the nut 5 that passes lug 3 between adjacent clamping plate 1, and four clamping plates 1 form integral body from beginning to end.
As this novel a kind of optimal way, pipe 2 is arranged on the center of the external arc of clamping plate 1.Pipe 2 is convenient to plug sleeve pipe, laborsaving jiggering.Pipe 2 is arranged on center rotary clamp more equably.
As this novel a kind of optimal way, be provided with annular knurl on the inner arc surface of clamping plate 1.Can increase coefficient of friction like this, improve the frictional force between itself and rotor journal, when avoiding jiggering, relative sliding occurs in both.
Concrete example is as follows, is 260mm(external diameter 300 mm with four inner diameter D shown in δ=40mm steel plate blanking manuscript 1) 1 ∕ 4 arc plates, bore the through hole of φ 25 mm in the middle of the lug at every arc plate two; (2) weld 1 φ, 40 * 150 mm round steel at every arc plate external diameter center.
By bolt 4 and four clamping plates 1 of lug 3 assemblings, be enclosed within on the axle journal of large rotating machinery equipment rotor, regulate its internal diameter size by four nuts 5 on the adjustment fixture, satisfying rotor journal is the needs of the slewing jiggering in φ 260～φ 300mm size range, then sleeve pipe is inserted on pipe 2, drives the equipment rotor by moving this fixture of rotating casing dish when deciding core and rotate together the purpose that reaches jiggering.
The jiggering fixture that this is novel because internal diameter is adjustable, in large rotating machinery equipment installation and repairing process, can conveniently be applied to the axle journal in the certain size scope, does not need the in-site measurement journal size to make the jiggering fixture temporarily again.This Novel rapid is applicable, has improved installation and repairing efficient, has reduced production cost.
