1, above-mentioned preparation method does not have the auxiliary making of frock, and operating efficiency is lower.
2, above-mentioned preparation method relies on artificial being difficult to guarantee to make precision, often does over again in the assembly shop, and the production efficiency of diesel engine is lower.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art; A kind of positioning fixture for welding of the 46MCC of being used for type U-shaped playpipe is provided; Characteristics simple, with low cost are drawn materials conveniently, made to this positioning fixture for welding; These anchor clamps make the welding of 46MCC type U-shaped playpipe only need a clamping just can make, and have ensured production of products precision and production efficiency.
Technical solution of the present invention is following:
A kind of U-shaped playpipe positioning fixture for welding that is used for the making of 46MCC type U-shaped playpipe; Its characteristics are that these anchor clamps are made up of baffle plate, locating piece, first cushion block, second cushion block, clamp and steel plate; On described steel plate, set firmly described clamp; Stride circular arc at two circular arc portions of described U-shaped playpipe symmetrically on the both sides of this clamp and radially respectively be installed with more than one second cushion block; Stride straight tube at two straight-tube portions of described U-shaped playpipe and be installed with first cushion block, locating piece and baffle plate successively; This clamp has notch and the fastening bolt that supplies latch segment to be provided with, and through the latch segment locking positioning of fastening bolt with U-shaped playpipe dome, the two ends of described first cushion block and second cushion block all have and corresponding screw in described pipe clamp two ends or pin-and-hole; Supply described pipe clamp to utilize bolt or alignment pin location, described locating piece has notch and the alignment pin that supplies described U-shaped playpipe to place.
Stride circular arc at two circular arc portions of described U-shaped playpipe and radially respectively set firmly 2 second cushion blocks.
Described clamp is formed by machined, through being threaded, latch segment is fixed on location and the clamping action that has played workpiece on the relevant position on the U-shaped pipe.
Described locating piece is to be used for locating pipe clamp on the U-shaped pipe, through the connection of alignment pin, pipe clamp is fixed on the relevant position on the U-shaped pipe, plays location and clamping action.
Described cushion block is to form with machined, has guaranteed the size of the horizontal direction of U-shaped pipe, has played the effect of location.
Described baffle plate is the size that is used for guaranteeing U-shaped pipe vertical direction, has played the effect of location.
Technique effect of the present invention is following:
46MCC type U-shaped playpipe of the present invention is made and in practical application shows, has been obtained following technological merit with positioning fixture for welding:
1, the present invention is formed by machined, has improved the making precision of 46MCC type U-shaped playpipe.
2, convenient mounting and clamping of the present invention has improved the production efficiency of 46MCC type U-shaped playpipe.
3, the present invention has advantages such as simple in structure, cheap, easy to use.
Description of drawings
Fig. 1 is the structural representation of U-shaped playpipe positioning fixture for welding of the present invention.
Fig. 2 is the assembling sketch map of U-shaped playpipe positioning fixture for welding of the present invention.
Fig. 3 is the side view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further, but should limit protection scope of the present invention with this.
See also Fig. 1-3; As shown in the figure; A kind of U-shaped playpipe positioning fixture for welding that is used for the making of 46MCC type U-shaped playpipe; Constitute by baffle plate 1, locating piece 2, first cushion block 3, second cushion block 4, clamp 5 and steel plate 6, on described steel plate 6, set firmly described clamp 5, stride circular arc at two circular arc portions of described U-shaped playpipe symmetrically on the both sides of this clamp 5 and radially respectively be installed with two second cushion blocks 4; Stride straight tube at two straight-tube portions of described U-shaped playpipe and be installed with first cushion block 3, locating piece 2 and baffle plate 1 successively; This clamp 5 has notch and the fastening bolt 13 that supplies latch segment 16 to be provided with, and through latch segment 16 locking positionings of fastening bolt 13 with U-shaped playpipe dome, the two ends of described first cushion block 3 and second cushion block 4 all have and corresponding screw in described pipe clamp two ends or pin-and-hole; Supply described pipe clamp to utilize bolt or alignment pin location, described locating piece 2 has notch and the alignment pin 11 that supplies described U-shaped playpipe to place.Baffle plate 1 is used for guaranteeing the vertical dimension of U-shaped playpipe; Locating piece 2 cooperates alignment pin 11 to locate the position of pipe clamp; First cushion block and second cushion block are used for guaranteeing the horizontal size of U-shaped playpipe, and clamp 5 cooperates fastening bolt 13 to guarantee the position of latch segment 16.
