Abstract
The invention relates to a fixture for machining of end faces of a bend. The fixture mainly applied to clamping the bend during machining of the end faces of the bend comprises a steel angle, a pair of first iron pads fixedly connected to the steel angle, a pair of second iron pads fixedly connected to the steel angle and a pair of pressure plates. The first iron pads and the second iron pads are evenly distributed on a circle. The first iron pads are horizontally arranged. The second iron pads are vertically arranged. The pressure plates are arranged outside the first iron pads. The pressure plates are both connected to the steel angle through compression bolts. According to the fixture, a pipe orifice end flange is positioned by one face and two pins, the pressure plates tightens the flange after the compression bolts are tightened, the bend is clamped, and machining of end faces of the bend can be achieved. The fixture is simple in structure and convenient to operate, manpower is saved, and machining efficiency is improved.
Description
Technical field
The present invention relates to a kind of processing bend pipe end face fixture, be mainly used in carrying out clamping to bend pipe in bend pipe end face process.
Background technology
In daily productive life, pipeline and we are closely bound up, the junction of pipeline is most important undoubtedly, if pipeline end face out-of-flatness, then can leave gap in the junction of pipeline, cause leakage, no matter be leak of liquid or Leakage Gas, serious threat is caused to the personal safety as well as the property safety of people in capital, visible, and the processing for pipeline end face can not be ignored.Traditional crooked pipeline shape is comparatively simple, even if having several bending, each adjacent bend pipe plane is also in same space, now can make according to the shape facility in each knee of bend pipe the mould that two have respective shapes die cavity, bend pipe is placed in die cavity, two moulds are fixed to one another, by bend pipe success clamping, thus the processing to bend pipe end face can be realized.
But use needs according to productive life, one as shown in Figure 5 special " distortion " bend pipe, each plane of bending of this bend pipe is all in different spaces from adjacent flex plane, is difficult to its clamping by means of prior art, and then brings difficulty to the processing of follow-up bend pipe end face.
Summary of the invention
Technical problem to be solved by this invention is: in order to solve the deficiency in prior art, complex-shaped bend pipe being difficult to clamping, a kind of processing bend pipe end face fixture is provided, is intended to solve the special bend pipe that such as each plane of bending and adjacent flex face be all in different spaces and is difficult to clamping and then the unmanageable problem of end face.
The technical solution adopted for the present invention to solve the technical problems is: a kind of processing bend pipe end face fixture, comprise angle bar, the first parallels be fixedly connected on for a pair on angle bar, be fixedly connected on the second parallels on angle bar and a pair pressing plate for a pair, a pair described first parallels and a pair second parallels are evenly distributed on circumferentially same, and a pair first parallels are horizontally disposed with, a pair second parallels are vertically arranged, described a pair pressing plate is arranged on the outside of the first parallels, and a pair pressing plate is all connected on angle bar by hold-down bolt.
In order to locate the flanged plate of square elbow mouth end, also comprise alignment pin and support nail, described second parallels offers the locating hole for interspersed alignment pin, the end of thread of described support nail 7 is fixed on pressing plate 4, and the other end of support nail 7 supports angle bar 1, and described alignment pin interts the locating hole on the through hole of flanged plate and the second parallels successively, thus flanged plate is pressed on the first parallels and the second parallels, meanwhile, regulate support nail and hold-down bolt, pressing plate one end is pressed on the first parallels.
The invention has the beneficial effects as follows: the one processing bend pipe end face fixture of the present invention's design, efficiently solving current techniques can not the problem of the special bend pipe of clamping, namely clamping such as each plane of bending and adjacent flex face is all in a difficult problem for the special bend pipe of different spaces, the structure of fixture is simple, easy to operate, save manpower, improve the working (machining) efficiency to bend pipe end face.

Detailed description of the invention
The present invention is described in detail by reference to the accompanying drawings now.This figure is the schematic diagram simplified, and only basic structure of the present invention is described in a schematic way, therefore it only shows the formation relevant with the present invention.
As Figure 1-3, one processing bend pipe end face fixture provided by the invention, comprise angle bar 1, the first parallels 2 be fixedly connected on for a pair on angle bar 1, be fixedly connected on the second parallels 3 on angle bar 1 and a pair pressing plate 4 for a pair, a pair described first parallels 2 and a pair second parallels 3 are evenly distributed on circumferentially same, and a pair first parallels 2 are horizontally disposed with, a pair second parallels 3 are vertically arranged, described a pair pressing plate 4 is arranged on the outside of a pair first parallels 2, and a pair pressing plate 4 is all connected on angle bar 1 by hold-down bolt 5.
As Figure 1-4, in order to locate the flanged plate a of square elbow mouth end, also comprising alignment pin 6 and support nail 7, described second parallels 3 offering the locating hole 31 for interspersed alignment pin 6, the end of thread of described support nail 7 is fixed on pressing plate 4, and the other end of support nail 7 supports angle bar 1.
Below in conjunction with Fig. 1-5, illustrate that the present invention designs the clamping process of fixture: be placed on by flanged plate a on the first parallels 2 and the second parallels 3, and make the two through hole on flanged plate a aim at locating hole 31 on the second parallels 3, insert alignment pin 6, limit the left and right of flanged plate a, freely up and down spend, now, pressing plate 4 one end is placed on the other two through hole of flanged plate a, tighten hold-down bolt 5, make pressing plate 4 supported flange plate a, so far limit the Anterior-Posterior of flanged plate a; Meanwhile, by regulating support nail 7, making support nail 7 tightly support pressing plate 4, limiting the free degree of pressing plate 4, thus make pressing plate 4 can stably supported flange plate a.The fixture of this invention design, effect solves current techniques can not the problem of the special bend pipe of clamping, namely clamping such as each plane of bending and adjacent flex face is all in a difficult problem for the special bend pipe of different spaces, the structure of fixture is simple, easy to operate, save manpower, improve the working (machining) efficiency for bend pipe end face.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff not departing from scope of the present invention, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
