The utility model is mainly proofreaied and correct automobile front axle and axle casing as check, thus in the selection to hydraulic press, the one, make travelling table to the height between pressure head should be not less than 250mm.The 2nd, the hydraulic cylinder ability should be not less than 60 tons.Adopt the single arm type hydraulic press in the present embodiment, as shown in Figure 1, for adapting to other operations such as dismounting cylinder sleeve, travelling table to the height between pressure head is got 640mm, and the hydraulic cylinder ability is 80 tons.1 is pressure head among Fig. 1, and 2 is table base, and 3 is the movable workbench handwheel, 4 is pressure head lifting joystick, configuration travelling table 5 is connected by guide tracked moving sets between travelling table 5 and the table base 2 on table base 2, adopts flat guide in the present embodiment.The rack-and-pinion transmission is handled by movable workbench handwheel 3.The utility model is for adapting to the correction operation of full-sized car axle, strengthened the size of table base 2, to guarantee that travelling table 5 has enough big stroke to be installed on the travelling table for handle securely by the verification workpiece, be provided with two fixed supports 6, the structure of fixed support 6 such as Fig. 2, shown in Figure 3.Have the spill card pressure mouth 10 that the card workpiece is used on carrier base 9, card presses the opening of mouth 10 to open up, also can open to a side.Be example shown in the figure, cover plate 12 be fixedly mounted on the opening part that card is pressed mouth 10, make card press mouth 10 four sides sealings blocking the workpiece of pressing in the mouth for fastening clip with bolt 13 to lateral opening.On card pressure mouthful sealing surface, establish one or two hold-down bolt 11, there is fixedly slotted hole 14 bottom surface of carrier base 9, with bolt fixed support is fastened on the travelling table 5 among Fig. 18 and is the tee-slot on the travelling table, moment of torsion frame 7 is members of proofreading and correct the automobile front axle torsional deformation, Figure 4 shows that an embodiment.Remove have on the son 15 can catch the automobile front axle end remove rim of the mouth 16 the both sides of removing son 15 with remove the rim of the mouth pivot center and vertically fixedly mount torque arm 17, remove son head and torque arm and can weld fixingly, or be cast as one.Remove daughter 15 and its turning cylinder is flatly place supporting base 18 tops, the contact-making surface of removing daughter and supporting base is the face of cylinder, and the center line on this face of cylinder overlaps with the center of rotation of removing daughter.19 is to be used to limit remove daughter and mobile mutually vertically positioning convex and the groove of supporting base among the figure, and pressure head acts on the vertical on the torque arm during operation.Can be decomposed into to the pressure of supporting base and around the simple bending square of removing a son turning cylinder to the pressure of supporting base by its support reaction balance, the simple bending square acts on the automobile axle head by removing the rim of the mouth, so the moment of torsion frame can be fixed on the travelling table.Also can not fix, be positioned on the workbench naturally and use.Fig. 6 Fig. 7, Figure 8 shows that and another embodiment of moment of torsion frame open a horizontal shaft hole at the top of supporting base 18, also open an axis hole removing son its turning cylinder of 15 upper edges.Be rotatably installed on the supporting base 18 removing sub 15 by axle 20 and above-mentioned axis hole, vertically fixedly mount torque arm 17 with its turning cylinder removing on the son 15, have and remove mouthful storehouse 21 removing son its rotating shaft direction of 15 upper edges, remove in mouthful storehouse 21 the setting-in activities and remove rim of the mouth 16.Remove mouthful gland 22 usefulness bolting and be installed in the openend of removing mouthful storehouse 21, rim of the mouth 16 is removed in activity to be pressed in and to remove in mouthful storehouse, remove mouth 16 as long as be equipped with the activity of one group of different size specification, remove the specification of mouth by changing activity, the automobile front axle of the various different sizes of recoverable, adaptability is strong, and is easy to use, the moment of torsion frame also can adopt the shape of the mouth as one speaks formula of fixedly removing, promptly in the embodiment shown in fig. 6.Mouth is removed in activity changed into and fixedly remove mouth, remove the son head for one and be applicable to that the automobile front axle of proofreading and correct a specification is equipped with one group and has different size and remove the sub-head of removing of rim of the mouth, then remove the method for son by replacing, can be to the correction operation that carries out of different size automobile front axle.23 is alignment pin among the figure, is used to prevent that axle from 20 deviating from, and 24 remove the excellent opening of testing of both sides, rim of the mouth for being positioned at.When proofreading and correct the automobile front axle torsional deformation, will test rod from testing the kingpin bore that excellent opening 24 injects the automobile end, be convenient to check and correction like this.

Application of the present utility model for example to the automobile front axle timing of testing, at first utilizes fixed support that automobile front axle is installed on the travelling table, is about to automobile front axle spring perch position and places in support bracket fastened card presses mouthful.Loading onto cover plate tightens with hold-down bolt again.With bolt fixed support is fixedly mounted on the travelling table then, as shown in Figure 1, for the axle two ends that detect or the flexural deformation at middle any position, can directly force in corresponding site with the hydraulic press pressure head is proofreaied and correct, must use the moment of torsion frame for torsional deformation, promptly moment of torsion is placed on the travelling table, makes it remove the rim of the mouth and block the automobile shaft end, force on the corresponding torque arm and can be proofreaied and correct with pressure head.The automobile axle shell produces flexural deformation, general all with the latch plate point of attachment near, promptly near the position, plane that diameter of axle inboard in two ends has processed.Timing is installed on axle casing on the fixed support, and it should be at latch plate point of attachment place that the supporting position is promptly proofreaied and correct at the position that is installed.The pressure head point of application is the outer rim of the back axle two ends conical surface.

The utility model has the advantages that: owing to the mechanism that is installed that has adopted on travelling table and the table top, hydraulic press that need only a pressure head can satisfy all correction operations, cubing is also utilized the general cubing of motor repair trade, and is simple with above-mentioned existing equipment comparative structure, cost is low. Because fixed support and moment of torsion frame are convenient to dismounting, be suitable for the automobile shafts of various different models, all can proofread and correct easily front axle, axle casing. After fixed support pulled down, namely can be used as common forcing press, be equipped with corresponding jig and also can carry out tension and compression cylinder block cylinder sleeve, a tractor serves several purposes is accomplished in shovel riveting differential mechanism rivet and other operations.
