The welding fixture for the rail wagon brake cylinder seat is used to weld the hanger plate and the seat plate and connection plate assembly, can improve product welding accuracy, and improves qualified rate.
Description
Technical field
The present invention relates to a kind of mechanical field, specifically a kind of welding tooling for rail wagon brake cylinder seat.
Background technology
The power of China railways freight car braking equipment is from the pressure-air of spinning seal type brake cylinder, and checking cylinder is connected on lorry by cylinder seat assembly.Cylinder seat assembly has corresponding model according to the checking cylinder of different model again, and usual cylinder seat composition comprises 2 seat boards, 24,2 connecting plates, 23,1 boatswain chair 22 and 1 forward flange dish 21 (see figure, Fig. 2).Order front cylinder base welding process flow is as follows: (1) once welds---and seat board 24 and connecting plate 23 assembly welding, form seat board, connecting plate assembly; (2) secondary welding---boatswain chair 22 and the seat board connecting plate assembly assembly welding in (1); (3) three welding---forward flange dish 21 and seat board connecting plate assembly assembly welding, complete cylinder seat.Because workpiece is steel sheet material moulding mixture group welding piece, wherein easily there is boatswain chair centre bore and seat board connecting plate assembly bottom surface apart from undesirable, boatswain chair and seat board connecting plate assembly out of plumb with the problem such as to be dislocated in second time welding, causes that positioning precision is poor, welding quality is wayward.
Summary of the invention
In order to easily occur when overcoming the welding of existing cylinder seat of brake cylinder that boatswain chair centre bore and seat board connecting plate assembly bottom surface are apart from undesirable, boatswain chair and seat board connecting plate assembly out of plumb and the deficiency that is dislocated, the invention provides a kind of welding tooling for rail wagon brake cylinder seat, this welding tooling floor space is little, easy to operate, this frock is adopted to weld boatswain chair and seat board connecting plate assembly, Product jointing precision can be improved, improve qualification rate.
Technical scheme of the present invention is: a kind of welding tooling for rail wagon brake cylinder seat, comprise support, described frame upper both sides are fixed with bearing block respectively, bearing block is provided with rotating shaft, clamp bottom board is fixed with between two rotating shafts, described clamp bottom board upper left-hand is fixed with fixture riser, and the right flank of fixture riser is fixed with collateral bracer, and fixture riser has the through hole matched with cylinder seat boatswain chair upper portion central hole; Described clamp bottom board top is fixed with locating piece and several lower support blocks, and the edge of clamp bottom board is connected with several pressing plates.
On the upside of described clamp bottom board, the right side of back-up block has the groove being parallel to fixture riser.
Located by alignment pin between described rotating shaft and bearing block.
The present invention has following beneficial effect: owing to taking such scheme, and clamp bottom board is connected in rotating shaft, can be controlled to rotate by rotating shaft, thus the diverse location of welding cylinder seat boatswain chair and seat board connecting plate assembly, improve welding quality and production efficiency; Boatswain chair, by collateral block supports, makes its horizontal level limit, and alignment pin is through the through hole on boatswain chair and fixture riser, and its upright position is limited, thus ensures the distance of boatswain chair centre bore and seat board connecting plate assembly bottom surface; Meanwhile, seat board connecting plate assembly is positioned by locating piece, can ensure that seat board connecting plate assembly is vertical with boatswain chair, avoids the two dislocation, improves welding precision.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
By shown in Fig. 3 to Fig. 5, a kind of welding tooling for rail wagon brake cylinder seat, comprise support 1, described both sides, support 1 top are fixed with bearing block 2 respectively, and bearing block 2 is provided with rotating shaft 3, located by alignment pin 5 between rotating shaft 3 and bearing block 2, namely rotating shaft 3 and bearing block 2 all have several holes, by rotating shaft 3, make different holes corresponding, alignment pin 5 is inserted rear spacing, thus make rotating shaft 3 be in different angles.Be fixed with clamp bottom board 14 between two rotating shafts 3, when rotating shaft 3 is rotated, clamp bottom board 14 can together rotate thereupon.Described clamp bottom board 14 upper left-hand is fixed with fixture riser 10, is fixed with two gripper shoes 11, fixture riser is played to the effect of support on the left of fixture riser 10.The right flank of fixture riser 10 is fixed with two collateral bracers 12, fixture riser 10 has the through hole matched with cylinder seat boatswain chair 22 upper portion central hole, and gripper shoe 11 and back-up block 12 are in above-mentioned through hole both sides.Fixture riser 12 is also processed with the screwed hole of level, and screwed hole corresponds to the blank space of boatswain chair 22, after boatswain chair 22 is spacing by alignment pin 5, by hold-down bolt 6 and on pressing plate boatswain chair 22 is fixed on fixture riser 10.
