The rotating station plate 3 is rotationally connected with the tool station plate 1 through a rotating shaft 17. The rotating station plate 3 is provided with a bearing 18 sleeved on the shaft body of the rotating shaft 17, and the bearing 18 enables the rotating shaft 17 to rotate flexibly. The bolts that the bearing 18 is mounted on the outside of the bearing 18 are tightly pressed and fastened, preventing the bearing 18 from being detached. Two ends of the rotating shaft 18 are arranged inside the tool station plate 1, and two ends are connected with bolts.

The outer side of the rotary station plate 3 is provided with a floating shaft 5. The plate body of the rotating station plate 3 is fixedly provided with a shaft seat 4, the shaft seat 4 is sleeved on the shaft body of the floating shaft 5, and the floating shaft 5 moves relative to the shaft seat 4. The shaft seat 4 functions to prevent the floating shaft 5 from moving away from the rotating station plate 3 and to restrict the floating shaft 5 from moving radially.

The bottom end of the floating shaft 5 is selectively connected with the standing plate positioning hole 2. The rotary station plate 3 is restricted to be in a vertical state when the floating shaft 5 is engaged with the station plate positioning hole 2, and the rotary station plate 3 can be rotated when the floating shaft 5 is separated from the station plate positioning hole 2.

The top of the floating shaft 5 is connected with a pressing limiting shaft 7 which rotates axially, and the pressing limiting shaft 7 is used for bearing a front axle of the frame. A limit plate 20 is arranged between the floating shaft 5 and the pressing limit shaft 7, and a clamp spring 21 is connected to the position, close to the limit plate 20, of the floating shaft 5. The side of the downward pressing limiting shaft 7 is provided with a hook shaft 8 extending in the radial direction, the rotating station plate 3 is provided with a limiting hook 9 matched with the hook shaft 8, and the arc opening of the limiting hook 9 faces downwards. The lower side of the limiting hook 9 is an inclined plane. The hook shaft 8 may be a bolt. The limiting hook 9 is used for limiting the downward pressing limiting shaft 7 and the floating shaft 5 to move upwards, so that the floating shaft 5 can be inserted into the station plate positioning hole 2 to a certain depth when the limiting hook 9 hooks the hook shaft 8, and the rotary station plate 3 cannot fall down in a vertical state.

The floating shaft 5 is provided with a spring 6 on the shaft body, the spring 6 is sleeved on the floating shaft 5, and the spring 6 is arranged between the shaft seat 4 and the limit plate 20.

The rotary station plate 3 is provided with a guide groove 19 matched with the lower limit shaft 7 at the position of the lower limit shaft 7. The top of the plate body of the rotating station plate 3 is provided with a limit pin 22, one end of the limit pin 22 extends to the outer side of the rotating station plate 3, the surface of the limit pin 22 is tangent with the surface of the downward pressing limit shaft 7, and the limit pin 22 guides the movement of the downward pressing limit shaft 7.

A rotary bottom plate 15 and a connecting section bar 16 are arranged between the two rotary station plates 3, two ends of the rotary bottom plate 15 are respectively connected with the bottom ends of the two rotary station plates 3, and the connecting section bar 16 is connected with the middle parts of the two rotary station plates 3.

The support shaft 11 and the bottom end of the tool station plate 1 are fixedly arranged on the tool bottom plate 10.

The support shaft 11 is used to support the rotating station plate 3 when the rotating station plate 3 falls down. The support shaft 11 corresponds in position to the rotary station plate 3. The top end of the supporting shaft is sleeved with a rubber pad 12 for shock absorption. A tension spring 13 is connected between the support shaft 11 and the rotating station plate 3. One end of a tension spring 13 is sleeved on the shaft body of the supporting shaft 11, and the other end of the tension spring 13 is connected with the rotary station plate 3 through a bolt and a rotary bottom plate 15. When the rotating station plate 3 is vertical, the tension spring 13 is in a free state, when the rotating station plate 3 falls down, the tension spring 13 is in a stretching state, the tension spring 13 plays a role in buffering when the rotating station plate 3 rotates, and the impact force phenomenon cannot occur.

The side of the tool station plate 1 is provided with a limiting seat 14 for limiting the rotation direction of the rotary station plate 3, the limiting seat 14 is arranged at a position close to the rotary bottom plate 15, and the limiting seat 14 is arranged at one side of the tool station plate 1 facing the support shaft 11. Spacing seat 14 passes through nut fixed mounting on frock station board 1, and spacing seat 14 surface is provided with the rubber pad of thickness 30mm simultaneously.

The working process of the front axle rotating tool is as follows:

in the initial state, the rotary station plate 3 is vertical, when the limit hook 9 hooks the hook shaft 8, the floating shaft 5 is inserted into the station plate positioning hole 2 for a certain depth, and the rotary station plate 3 cannot fall down in the vertical state.

When the front axle rotating tool is used for assembling a front axle of a frame, the downward pressing limiting shaft 7 is pressed through the self weight of the frame, the downward pressing limiting shaft 7 and the floating shaft 5 move downwards, meanwhile, the inclined plane of the limiting hook 9 plays a role of downward pressing the limiting shaft to drive the hook shaft 8 to rotate so as to be separated from the hook position, and the bottom end of the floating shaft 5 props against the bottom surface of the standing plate positioning hole 2 to be stressed, so that the assembly line assembly operation can be carried out.

Referring to fig. 4, when the assembly line automatically flows to the end point inductive switch when the whole machine is assembled, the inductive switch enables the assembly line to automatically pause, after the lifting platform rail is lifted to support the whole machine, because the limiting shaft 7 is pressed down instantly and pressure is lost instantly, the spring 6 bounces to drive the floating shaft 5 to pull out the station plate positioning hole 2, the rotary station plate 3 automatically buffers the position which rotates forwards to the rubber pad 12 pressing the supporting shaft 11 through the tension spring 13, the whole height of the front axle rotary tool becomes low, and thus the whole machine can be directly started to be offline for subsequent debugging work.

After the whole vehicle is off-line, the rotating station plate 3 is manually rotated, so that the front axle rotating tool returns to the initial state.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
