Specific embodiment
As shown in figure 3, car seat headrest bar reducing device of the present invention includes revolving contracting disk 1 and gripping block 2, gripping block 2
In the right side of rotation contracting disk 1, to position car seat headrest bar 3 ' to be processed.
As shown in Figure 4 and Figure 5, rotation contracting disk 1 includes cylindrical chuck 13, and coaxial motor is provided in chuck 13
The chuck 13 is driven to rotate, motor do not show in view inside chuck.Chuck 13 towards ring on the end face of locating piece 2 wherein
It is rectangular radially-directed slot 131 that heart line, which is evenly distributed with three sliver transvers sections, is mounted on cross section in every radially-directed slot 131 and is
The rotation contracting wheel support 12 of the strip of T font, and its radially movement of guide groove 131 is driven with hydraulic device.Revolve contracting wheel support
12 radial motion makes car seat headrest bar 3 ' realize that necking is processed in a manner of radial force, avoids because axial force is excessive
Caused bulging and straightness decline problem.Its center line of ring, which is evenly distributed with three rotation contracting wheel supports 12, on the right side of chuck 13 makes vapour
The radial pressure of vehicle seats head rest pole 3 ' being subject to is more uniform, avoids stress from concentrating and generates local deformation.Revolve contracting wheel support 12
T font cross section narrow end it is identical as the cross section of radially-directed slot 131, both ensure that rotation contracting wheel support 12 in radially-directed
The direction of motion in slot 131 also carries the power that chuck 13 drives rotation contracting wheel support 12 to rotate.Contracting wheel support 12 is revolved close to institute
The one end for stating the center line of chuck 13 is provided with notch 121, and first shaft hole 122 is provided on 121 side wall of notch, first shaft hole 122
The centerline parallel of center line and the chuck 13.As shown in fig. 7, the center line of rotation contracting wheel 11 is equipped with the second axis hole 114.Rotation
Contracting wheel 11 is by being mounted on the slot for revolving contracting wheel support 12 with the central axis 14 of first shaft hole 122 and the cooperation of the second axis hole 114
In mouth 121, makes rotation contracting wheel 11 after contacting with car seat headrest bar 3 ', relative rotation is kept between contact surface, avoids generating
Rub scratch.
As Figure 6-Figure 8, rotation contracting wheel 11 is formed by connecting by coaxial big cylinder 113 and small column 112, revolution shape
It ensure that the balance of its own rotation.With the connection of concaved circular cambered surface 111, concaved circular cambered surface between big cylinder 113 and small column 112
Rotation contracting wheel 11 center line one week described in 111 rings, the section radius of concaved circular cambered surface 111 are 6mm, and the radius of big cylinder is 25mm, small
The radius of cylinder is 22mm, so that concaved circular cambered surface 111 and the port cambered surface 31 ' of car seat headrest bar 3 ' is matched, ensure that vapour
The necking size of vehicle seats head rest pole 3 '.
In use, hydraulic device driving rotation contracting wheel support 12 is first allowed to move, rotation contracting wheel 13 is set to deviate chuck hub line certain
Distance, then car seat headrest bar 3 ' to be processed is put into gripping block 2 and is clamped positioning, later motor driven card
Disk 13 rotates, while hydraulic device driving rotation contracting wheel support 12 moves, and keeps rotation contracting wheel 11 gradually mobile to the center line of chuck 13,
Until center line of the center line of rotation contracting wheel 11 apart from chuck 13 is 18mm, the necking processing of car seat headrest bar 3 ' is completed.
Above-described embodiment is only that the preferred embodiment of invention is described, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various modifications that case is made should all be fallen into the protection scope that claims of the present invention determines.
