Abstract

The utility model relates to a bus spare part processing technology field relates to a three -dimensional bending roll machine rectangular pipe chuck. Flange board and mounting panel by connecting are each other constituteed, set up the bolt hole that the annular was arranged on the flange board, flange board lower part is placed in to the mounting panel, and transversal trapezoidal first centre gripping hole, the transversal circular shape second centre gripping hole of personally submitting of personally submitting that is linked together is each other offered to the inside of mounting panel, and first centre gripping hole cross sectional area is greater than the cross sectional area in second centre gripping hole, the bottom of mounting panel is placed in second centre gripping hole, first centre gripping hole with run through on the flange board, transversally personally submit trapezoidal third centre gripping hole intercommunication. Through the bolt hookup, can carry out the stick and change when the chuck damages, do not need overall change, practice thrift cost of maintenance, be favorable to the maintenance and management of chuck, be fit for pressing from both sides the rectangular pipe that tight interface shape is complicated, can concentrate by stress relieving at the in -process that bends, fix a position the accurate rectangular pipe surface that makes and in back flawless and the deformation of bending, improve product quality.

Description

A kind of three-dimensional roll bending machine rectangular tube chuck
Technical field
This utility model relates to passenger vehicle parts machining technical field, is specifically related to a kind of three-dimensional roll bending machine rectangular tube chuck.
Background technology
Rectangular tube interface type number is of a great variety at present, and some rectangular tube bending radius of Bus Frame is relatively big, and surface quality requirements is high, Various dimensions bend.The three-dimensional roll bending machine rectangular tube chuck majority that market is bought is regular rectangular shape pipe (interface is rectangle) chuck, different The chuck that shape (interface dimensions is complicated) rectangular tube is not suitable for.Owing to needs produce abnormity rectangular tube, and press-bending side in enormous quantities Radian prescription is the highest, needs according to existing three-dimensional roll bending machine design a abnormity rectangular tube chuck.
Utility model content
For technical problem present in prior art, the purpose of this utility model is to provide a kind of simple in construction, location convenient Three-dimensional roll bending machine rectangular tube chuck.
To achieve these goals, the technical scheme that this utility model is used is: a kind of three-dimensional roll bending machine rectangular tube chuck, by The flanged plate being connected to each other and installing plate composition, flanged plate offers the bolt hole of annular arrangement;Installing plate is placed under flanged plate Portion, the inside of installing plate offers the first trapezoidal clamping hole of the logical cross section that is connected with each other, the second folder of circular in cross-section Holding hole, the first clamping hole cross-sectional area is more than the cross-sectional area in the second clamping hole;Second clamping hole is placed in the bottom of installing plate, First clamping hole with on flanged plate, cross section trapezoidal the 3rd clamp hole connect.
3rd clamps hole flare opening shape, and its four corner locations offer arc elongated slot.
The both sides up and down in the second clamping hole all offer moves back platform.
This chuck is spliced by the monomer of 6 deciles, and each monomer is split to form according to 6 deciles on flanged plate, during use Against each other and combine.
Three-dimensional roll bending machine rectangular tube chuck of the present utility model, its beneficial effect shows:
1, three-dimensional roll bending machine grip holder split blade type flexible structure, it is possible to realize clamping normally, unclamping action.
2, three-dimensional roll bending machine grip holder simple in construction, by bolt-connection, can carry out single-piece replacing when chuck damages, it is not necessary to Integral replacing, saves maintenance cost;Be conducive to the maintenance and management of chuck.
3, embedded split blade type structure chuck is suitable for clamping the rectangular tube that interface shape is complicated.
4, three-dimensional roll bending machine grip holder rectangular tube can eliminate stress concentration in press bending process, and accurate positioning makes rectangular tube surface Flawless and deformation after press-bending, improve product quality.
5, three-dimensional roll bending machine grip holder is convenient owing to changing, it is possible to effectively improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of three-dimensional roll bending machine rectangular tube chuck.
Fig. 2 is the line A-A sectional view in Fig. 1.
Fig. 3 is the working state schematic representation of three-dimensional roll bending machine.
Detailed description of the invention
For further describing this utility model, with embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of three-dimensional roll bending machine rectangular tube chuck shown in Fig. 1 and 2, is made up of flanged plate 11 and installing plate 12, has 6 The monomer of decile mutually splices, and each monomer is split to form according to 6 deciles on flanged plate 11, against each other and group during use Close.
Offering the bolt hole 16 of annular arrangement on flanged plate 11, installing plate 12 is placed in flanged plate 11 bottom, installing plate 12 Inside offer the logical cross section that is connected with each other trapezoidal first clamping hole 13, circular in cross-section second clamping hole 15, First clamping hole 13 cross-sectional area is more than the cross-sectional area in the second clamping hole 15;Second clamping hole 15 is placed in installing plate 12 Bottom.
First clamping hole 13 with on flanged plate 11, cross section trapezoidal the 3rd clamp hole 14 connect.3rd clamping Hole 14 flare opening shape, and its four corner locations offer arc elongated slot 17.The both sides up and down in the second clamping hole 15 All offer and move back platform.
Referring to Fig. 3, be arranged in three-dimensional roll bending machine by above-mentioned chuck 6, the outer ring 4 of three-dimensional roll bending machine drives interior briquetting 5 one Playing side-to-side movement, interior briquetting 5 (annulus steel) is connected with the flanged plate 11 of chuck 6, by outer ring 4 by 6 M6 bolts Move back and forth, briquetting 5 in compression so that chuck 6 tensioning together with interior briquetting 5 is shunk.Control system controls cylinder 1 and stretches, Driving first connecting rod 1, second connecting rod 2 to move (pin joint between the two is movably connected on fixed mount 8), second even Bar 2 drives outer ring 4 to move back and forth in the horizontal direction;When circle to overhanging (to the right) time, interior for compression briquetting 5 is made chuck 6 Compress together, final chuck 6 clamp rectangular pipe 7;Time when outer ring inside contracts (to the left), interior briquetting 5 discharges, chuck 6 open together with interior briquetting 5 outward, and final rectangular tube 7 is released.
Above content is only to design example of the present utility model and explanation, affiliated those skilled in the art couple Described specific embodiment makes various amendment or supplements or use similar mode to substitute, without departing from utility model Design or surmount scope defined in the claims, protection domain of the present utility model all should be belonged to.
