The utility model provides a flaring device for assembling a wheel side assembly of a passenger vehicle, in particular to the assembly of a Macpherson type suspension wheel side assembly.
As shown in fig. 2, the macpherson suspension wheel-side assembly mainly comprises a shock absorber 1, a knuckle 2 and other parts, wherein the knuckle 2 is provided with a mounting hole d which is in interference fit with a sliding column of a threaded rod 5 in the shock absorber 1, and the interference magnitude is generally 0.03-0.2 mm. Therefore, during assembly, it is necessary to first expand both sides of the mounting hole d in the a and b directions, then insert the strut of the damper 1 in the c direction, and finally tighten the bolt.
The flaring device for assembling the wheel side assembly of the passenger vehicle has a main structure shown in figure 3 and comprises a baffle plate 3, an opening bracket 4, a threaded rod 5 and a screwing rod 6. One side of the open bracket 4 is open, the other side of the open bracket 4 is provided with a threaded hole, the threaded rod 5 is screwed into the open bracket 4 through the thread, and the screwing rod 6 penetrates into the threaded rod 5. The whole open bracket 4 needs to be subjected to thermal refining to improve the strength of the bracket.
As shown in fig. 6, the baffle 3 can be vertically inserted into the opening of the open bracket 4, and the top of the baffle 3 is provided with a flange, as shown in fig. 8, the size of the flange is larger than the opening gap f, the baffle 3 can be clamped at the opening of the mounting hole d, and the baffle can be prevented from falling into the steering knuckle mounting hole d in the using process. As shown in fig. 7, the whole length L of the baffle 3 should not be too long, so as to avoid interference when the shock absorber strut is inserted into the knuckle mounting hole d.
The opening bracket 4 is composed of 2 hook claws and a connecting block for connecting the two hook claws. The inner surfaces of the two hook claws at the opening end are adhered with nylon sheets, and the nylon sheets are soft materials, so that damage to the steering knuckle when the steering knuckle is in contact with the steering knuckle can be reduced. When the hook claw is in contact with the steering knuckle 2, the hook claw is in plane contact, and the damage of the flaring device to a sample piece in the using process is greatly reduced. In addition, the hook claw is damaged and can be replaced. The middle part of the connecting block is provided with a threaded hole.
The threaded rod 5 is formed by turning and milling integrally, one end of the threaded rod is provided with an external thread, the other end of the threaded rod is sleeved with a sleeve, the inner cavity of the sleeve is hexagonal prism-shaped, the sleeve is provided with an internal thread, the sleeve is in threaded connection with the threaded rod 5, a through hole penetrating the sleeve is formed in the middle of the sleeve in the X-axis direction, and a hexagonal bolt head in threaded connection with the sleeve is installed at the end of the threaded rod 5 on the outer side of the sleeve in the Y-axis direction.
The screwing rod 6 penetrates through a through hole in the X-axis direction of the sleeve and is in interference fit with the sleeve. When screwing the threaded rod 5, the electric gun can be used for assisting screwing, but if the electric gun is needed to be used, the screwing rod 6 needs to be disassembled, and the flying-out during rotation is avoided. When the threaded rod 5 needs to be screwed manually, the screwing rod 6 is installed, and due to the lever principle, labor is saved when the threaded rod is screwed manually. Owing to possess above two kinds of tightening methods, this frock can use under any operating mode.
As shown in fig. 4 and 5, when the flaring device is used, the opening bracket 4 is firstly sleeved on one side of the steering knuckle mounting hole d, then the threaded rod 5 is screwed in, meanwhile, the threaded rod 5 penetrates into the steering knuckle assembling bolt hole e, and the threaded rod 5 is in clearance fit with the steering knuckle assembling bolt hole e; because the steering knuckle assembling bolt hole e penetrates through two sides of the whole steering knuckle mounting hole d, the other side of the steering knuckle mounting hole d needs to be blocked by the blocking piece 3 in the expansion process; then screwing the threaded rod 5, and after the threaded rod abuts against the blocking piece 3, the opening bracket 4 drives one side of the steering knuckle mounting hole d to move through two hooked claws at the opening end due to the reaction force of the blocking piece 3, so that the steering knuckle mounting hole d is expanded; and finally, installing the shock absorber 1 to finish assembly.
