Background technology:

Vehicle bridge rod axle belongs to slender axles, after forging and heat treatment, under portioned product portion's stress effect within it, is easy to generate bending, causes its radial beat eccentricity to exceed standard, thereby, must be by alignment process, so that its radial beat eccentricity is controlled within the scope of specification requirement.

Alignment process of the prior art generally comprises two steps: the first, by testing tool it is examined entirely earlier, and distinguish the portioned product that radial beat eccentricity exceeds standard; The second, by beating that part of product alignment that radial beat eccentricity is exceeded standard by hand.Though this kind method is feasible, its branch is done two steps and is carried out, and the inconvenience that operates and production efficiency are low, and in addition, the manual hammering increased working strength of workers.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the quick coalignment of a kind of detection simultaneously and alignment, the easy to operate and axle shaft that production efficiency is high, labour intensity is low is provided.

The quick coalignment of a kind of axle shaft that provides according to the utility model, comprise the alignment depression bar, be installed in two groups of movable supporting and two groups of fixed supports on the workbench respectively, wherein, two groups of fixed supports place between two groups of movable supporting, connect by two connecting axles that be arranged in parallel between two groups of movable supporting, treat that the two ends of alignment axle shaft are placed on respectively on two groups of movable supporting.

The utility model also has following attached technical characterictic:

Each organizes the portable plate that described movable supporting includes base, is vertically fixed on the bearing on the base and is hinged on the bearing upper end, each portable plate inboard all is connected with a plate, two horizontally disposed rolling bearings all are installed on each connecting plate, are used for supporting respectively described two ends for the treatment of the alignment axle shaft.

All have kidney slot on each described portable plate, one caging bolt end passes this kidney slot and is connected with described base, one tension spring is coated on the caging bolt, its upper end is replaced with the portable plate lower surface, lower end and base upper surface are replaced, under the tension force effect of tension spring, the lower surface of portable plate upper surface and caging bolt head end is replaced.

Each described base all slidably is installed on the described workbench by pulley.

The upper surface of described alignment depression bar lower surface and described fixed support all has arc groove, and this arc groove can cooperate with the periphery wall for the treatment of the alignment axle shaft.

Also be equipped with on the described workbench and detect the described dial gauge device for the treatment of alignment axle shaft radial beat eccentricity.

The quick coalignment of a kind of axle shaft that provides according to the utility model with respect to the advantage of prior art is:

In the utility model, the two ends for the treatment of the alignment axle shaft are placed on respectively on two groups of movable supporting, with the dial gauge device its position is detected,, can directly be driven the alignment depression bar alignment is carried out in this position as finding the circular runout place that exceeds standard, very convenient, and realized that detection and alignment carry out simultaneously on same equipment, improved production efficiency, simultaneously, the alignment depression bar has effectively reduced working strength of workers by hydraulic-driven.

The specific embodiment:

Referring to figs. 1 through Fig. 5, the quick coalignment of a kind of axle shaft that provides according to the utility model, comprise alignment depression bar 1, be installed in two groups of movable supporting 3 and two groups of fixed supports 4 on the workbench 2 respectively, wherein, two groups of fixed supports 4 place between two groups of movable supporting 3, connect by two connecting axles that be arranged in parallel 5 between two groups of movable supporting 3, the two ends for the treatment of alignment axle shaft 11 are placed on respectively on two groups of movable supporting 3, each group movable supporting 3 includes base 31, be vertically fixed on bearing 32 and the portable plate 33 that is hinged on bearing 32 upper ends on the base 31, each portable plate 33 inboard all is connected with a plate 34, two horizontally disposed rolling bearings 35 all are installed on each connecting plate 34, be used for supporting respectively the two ends for the treatment of alignment axle shaft 11, and guarantee that it can easily rotate, all have kidney slot 36 on each portable plate 33, one caging bolt, 6 ends pass this kidney slot 36 and are connected with base 31, one tension spring 7 is coated on the caging bolt 6, its upper end is replaced with portable plate 33 lower surfaces, lower end and base 31 upper surfaces are replaced, under the tension force effect of tension spring 7, the lower surface of portable plate 33 upper surfaces and caging bolt 6 head ends is replaced, when the setting of kidney slot 36 is to guarantee alignment, portable plate 33 can rotate around itself and bearing 32 hinged places smoothly, and can not be subjected to stopping of caging bolt 6.

Each base 31 all slidably is installed on the workbench 2 by pulley 8, this quick coalignment can freely under hand propelled be moved on workbench 2, guarantee easily will treat rapidly on the alignment axle shaft 11 that the radial beat eccentricity part that exceeds standard moves to alignment depression bar 1 lower end, so that it is carried out alignment, the upper surface of alignment depression bar 1 lower surface and fixed support 4 all has arc groove 41, this arc groove 41 can cooperate with the periphery wall for the treatment of alignment axle shaft 11, also is equipped with on the workbench 2 to detect the dial gauge device 9 for the treatment of alignment axle shaft 11 radial beat eccentricitys.

Comprehensively described, this quick coalignment is when work, to treat that earlier alignment axle shaft 11 is placed on the rolling bearing 35 on the connecting plate 34, with dial gauge device 9 its each position is detected then, to seek out the position that radial beat eccentricity exceeds standard, during detection, available hand rotates treats alignment axle shaft 11, it is rotated on rolling bearing 35, guarantee that each position all detects, as detected radial beat eccentricity and exceed standard, promptly promote this quick coalignment, the position that will exceed standard places alignment depression bar 1 lower end, the primer fluid pressure device moves down alignment depression bar 1 then, alignment depression bar 1 lower end arc groove 41 with treat alignment axle shaft 11 cooperate replace after, treat that alignment axle shaft 11 also continues to move down under the pressure of alignment depression bar 1, at this moment, portable plate 33 compressive tension springs 7 also are rotated down around itself and bearing 32 hinged places, up to treat alignment axle shaft 11 cooperate with arc groove 41 on the fixed support 4 replace after, treat that alignment axle shaft 11 can not continue to move down, and under the pressure of alignment depression bar 1, obtain alignment.After alignment is good, each parts is resetted, and then detect, alignment again, so circulation can will be treated 11 alignments of alignment axle shaft fast and effectively.
