Description
Technical field：
The utility model is related to the production labor dresses of fluid torque-converter, are exactly specifically a kind of turbine core circle and blade point
The fixing device of weldering.
Background technology：
The pump impeller of torque-converters before assembly, needs that first blade is uniformly welded on core circle, at this stage using direct point
Welding method, it is this using being manually welded on blade successively on core circle or by blade direct spot welding on pump impeller shell ontology
Welding manner has the following disadvantages：Operate it is cumbersome, welding trouble, labor intensity is big, and working efficiency is low, since blade is equal
Even distribution, specific bond pad locations are not easily controlled, and are increased spot welding difficulty, are affected product quality.Therefore, our company Shen
Please application No. is 201410463970.5 patent, but in actual use, the workpiece for finding to assemble is installed to mash welder
When upper, in case of colliding, it occur frequently that the problem of core circle micro-shifting position, it was found, and seriously affected since this micro-shifting position is extremely difficult
The product quality of fluid torque-converter.
Utility model content：
The utility model is exactly to overcome deficiency of the prior art, provides consolidating for a kind of turbine core circle and blade spot welding
Determine device.
The utility model provides following technical scheme：
A kind of turbine core circle and the fixing device of blade spot welding, it includes fixed seat, a uniformly distributed group welding in fixed seat
Through-hole and one group of positioning pin, each positioning pin are corresponding with a welding connecting hole, it is characterised in that：It is set in fixed seat
There is round platform, positioning plate is equipped on round platform, the screw shell of protrusion, the positioning plate in screw shell both sides are equipped on positioning plate
Screw hole is equipped with, one group of limited block with blade corresponding matching is evenly equipped on the periphery of positioning plate, is covered on screw shell
Equipped with the pressing plate with positioning plate corresponding matching, the pressing plate connect cooperation with positioning plate by the screw with screw hole corresponding matching.
Based on the above technical solution, there can also be technical solution further below：
One group of extension is extended outward on the pressing plate, downward card is equipped in the end of each extension
Pawl.
Round platform, positioning plate, screw shell and the pressing plate is coaxial arrangement.
Groove is equipped in the fixed seat bottom.
Utility model advantage：
The utility model is simple in structure, easy to assembly, and core circle and blade accurate positioning are secured after equipment, avoid existing
After the collision of workpiece present in technology the problem of core circle micro-shifting position, the working efficiency of core circle and blade spot welding is effectively improved,
Ensure the product quality of fluid torque-converter.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment：
As shown in Figure 1, a kind of turbine core circle and the fixing device of blade spot welding, it includes the fixed seat 1 of bowl-type, in fixation
A uniformly distributed group welding through-hole 1c and one group of positioning pin 3 on the inner wall of seat 1, each positioning pin 3 with a welding connecting hole 1c
It is corresponding.Groove 1d is equipped in 1 bottom of fixed seat.
It is set in the bottom circle centre position of fixed seat 1 there are one the round platform 2 to raise up, the circle centre position in 2 upper surface of round platform is set
There are one cylindrical boss 2a.One round positioning plate 4 with 2 corresponding matching of round platform is set, on round 4 bottom surface of positioning plate
Equipped with the slot 4c with boss 2a corresponding matchings, it is connected through a screw thread between the boss 2a and slot 4c.
Circle centre position in the upper surface of positioning plate 4 is equipped with the screw shell 5 of protrusion, the positioning plate 4 in 5 both sides of screw shell
On be respectively equipped with screw hole 4a, one group of limited block 4b with blade 1b corresponding matchings is evenly equipped on the periphery of positioning plate 4, it is described
One group of limited block 4b be distributed into ratchet-like so that form one between two adjacent limited block 4b and corresponding with positioning pin 3 match
The skewed slot of conjunction.
When in use, it is only necessary to blade 1b one end is inserted into skewed slot, the other end coordinates with corresponding positioning pin 3, just
Blade can be positioned.After all blade 1b are put into fixed seat 1, the core circle 1a of opening upwards is placed on blade 1b
Suitable position.
The pressing plate 6 with 4 corresponding matching of positioning plate is arranged on screw shell 5, is extended outward on the pressing plate 6
The extension 6b of four crosswise distributions is equipped with downward claw 6c, the claw in the end of each extension 6b
6c is caught in downwards in core circle 1a, so as to which further core circle 1a is pressed on blade 1b, then by screw 6a and positioning plate 4
Screw hole 4a cooperation, by pressing plate 6 be fixed to positioning plate 4 on.
Round platform 2, positioning plate 4, screw shell 5 and the pressing plate 6 is coaxial arrangement, and is set in the circle centre position of pressing plate 6
There is the through-hole with the fixing axle corresponding matching on mash welder list welding stage.
The fixed seat after assembling is tipped upside down on mash welder point welding stage, then fixing axle is inserted into the through-hole during spot welding,
It is then connected with screw shell so that whole device is fixed on a welding stage, and then the welding gun on mash welder stretches into welding
Spot welding is carried out in through-hole to blade and core circle to fix.The groove of fixed seat bottom so that by fixed seat on mash welder list welding stage
The thumb of worker, which can be stuck in groove, during handling ensures handling safety.
