A material guide groove 41 is arranged on the material guide seat 39 below the material barrel 40; the depth of the material guiding groove 41 is consistent with the thickness of the clamp spring, so that the lowest clamp spring in the material barrel 40 can be ensured to fall into the material guiding groove 41 during operation, and the clamp spring can move along the material guiding groove 41 when being stressed, thereby avoiding the problem of jamming during movement.

A feeding push plate 43 is arranged in the guide chute 41 in a sliding manner through a feeding cylinder 42; the end of the material guiding groove 41 is provided with a clamping opening 44 (see the description and the attached figure 15). When the clamping device works, the feeding push plate 43 can push the clamp spring to a position corresponding to the clamping opening 44 along the material guide groove 41; after the clamp spring moves to the position of the clamping opening 44, the clamp spring jaw cylinder 37 can take out the corresponding clamp spring through the clamping opening 44.

The frame 1 above the pulling cylinder 35 is provided with a press fitting sleeve 47 through a press fitting cylinder 46 (see the description attached to fig. 10 and 11). The inner diameter of the press-fitting sleeve 47 is consistent with that of the clamp spring, and the press-fitting sleeve 47 can complete the assembly work of the clamp spring in a mode of pressing down the clamp spring during work.

A transverse sliding plate 4 is arranged on the rack 1 below the puller 2 and the clamp spring press-fitting device 3 in a sliding manner through a guide rail; a transverse cylinder 5 is arranged on the frame 1 at one side of the transverse sliding plate 4; the transverse cylinder 5 is connected with the transverse sliding plate 4 (see the description and the attached figure 8). The transverse cylinder 5 can drive the transverse sliding plate 4 to transversely slide back and forth along the guide rail when working.

The transverse sliding plate 4 is provided with a longitudinal sliding plate 6 in a sliding way through a sliding rail; the transverse sliding plate 4 on one side of the longitudinal sliding plate 6 is provided with a longitudinal cylinder 7 (see the attached figures 8 and 9 in the specification). The longitudinal cylinder 7 is connected with the longitudinal slide 6. The longitudinal cylinder 7 is operated to drive the longitudinal sliding plate 6 to slide back and forth on the transverse sliding plate 4.

The longitudinal sliding plate 6 is provided with a supporting clamp 8 (see the attached figure 8 in the specification). A limiting clamping plate 48 is arranged on the longitudinal sliding plate 6 at the inner side of the supporting clamp 8; the limit catch plate 48 is provided with a limit catch groove 49 (see the description attached to fig. 8 and 9).

The support fixture 8 comprises a support sleeve 11, a bottom plate 13, a floating plate 15 and a quick clamp 18 (see the description of figure 9).

The longitudinal sliding plate 6 is provided with a supporting sleeve 11; a bottom plate 13 is fixedly arranged above the supporting sleeve 11 through an upright rod 12; a floating plate 15 is arranged on the bottom plate 13 through a guide sliding rod 14; the guide slide bar 14 below the floating plate 15 is sleeved with a buffer spring 16 (see the description and the attached figure 9). The floating plate 15 is pressed to move downward against the elastic force of the buffer spring 16.

The floating plate 15 and the bottom plate 13 are provided with mutually corresponding limiting ports 17; the bottom plate 13 at one side of the limiting opening 17 is provided with a quick clamp 18. The quick clamp 18 is a commercially available component.

During assembly, a workpiece to be assembled can be placed on the supporting sleeve 11, the workpiece is abutted against the limiting opening 17, and then the workpiece is pressed through the quick clamp 18 to be fixedly connected with the bottom plate 13.

A limiting sliding plate 10 is arranged on the machine frame 1 between the upper part of the longitudinal sliding plate 6 and the drawing device 2 through a control cylinder 9. The end of the limiting slide plate 10 is provided with a limiting bayonet 45 (see the attached figure 8 in the specification).

When the pull shaft and clamp spring assembling device of the automobile pipe column works, firstly, a workpiece to be assembled is placed on a supporting sleeve 11 of a supporting clamp 8, the workpiece is close to a limiting opening 17, and a spline shaft in the workpiece is close to a limiting clamping groove 49 of a limiting clamping plate 48; the workpiece is then pressed by the quick clamp 18 to remain fixedly connected to the base plate 13.

After the assembly of the workpiece to be assembled is finished, the longitudinal cylinder 7 works to drive the longitudinal sliding plate 6 to move the workpiece to the lower part of the drawing device 2 through the supporting clamp 8. The female thread bush 28 in the puller 2 corresponds to the spline shaft of the workpiece. Then the control cylinder 9 drives the limiting sliding plate 10 to approach the spline shaft, and finally the limiting sliding plate is in fit connection with the spline shaft through the limiting bayonet 45 (see the attached figure 1 in the specification), and the lower end face of the limiting sliding plate 10 is in fit connection with the end face of the upper pipe column of the workpiece. Set up spacing slide 10's aim at: so that during operation, during the spline shaft upward movement process, the limiting slide plate 10 can limit the parts (including the bearing) inside the upper pipe column of the workpiece inside the upper pipe column through the lower end surface, so as to avoid the problem that the parts (including the bearing) inside the upper pipe column are separated from the upper pipe column along with the spline shaft moving upward.

After the above steps are completed, the drawing cylinder 19 of the drawing device 2 drives the internal thread sleeve 28 to move downwards through the upper transmission plate 20, the guide slide rod 21, the upper assembling plate 23 and the lower assembling plate 26; the servo motor 27 drives the internal thread sleeve 28 to synchronously rotate in the downward moving process of the internal thread sleeve 28. Thus, when the female sleeve 28, which has been rotated downward, is held in threaded engagement with the male threads of the spline shaft on the workpiece, the female sleeve 28 stops rotating and moves downward.

The drawing cylinder 19 of the puller 2 then moves the spline shaft up to the designated position by means of the upper transmission plate 20, the guide slide 21, the upper and lower

fitting plates

23, 26 and the internally threaded sleeve 28. In the process, the pulling pressure sensor 24 can monitor the pulling force of the puller 2, and the puller 2 can give an alarm when the pulling force is too large, so that the risk of safety accidents is reduced.

When the spline shaft moves up to a designated position, a drawing cylinder 19 of the drawing device 2 drives an internal thread sleeve 28 to move up through an upper transmission plate 20, a guide sliding rod 21, an upper assembling plate 23 and a lower assembling plate 26; in the process, the servo motor 27 drives the internal thread sleeve 28 to synchronously rotate in the reverse direction, and the internal thread sleeve 28 is gradually disconnected from the spline shaft. When the internal thread bush 28 is completely disconnected from the spline shaft, the internal thread bush 28 stops moving, and the drawing cylinder 19 drives the internal thread bush 28 to move upwards for resetting.

After the puller 2 is reset, the transverse cylinder 5 drives the transverse sliding plate 4 to move towards the clamp spring press-mounting device 3, and when the transverse sliding plate 4 drives the workpiece to move below the press-mounting sleeve 47 through the longitudinal sliding plate 6 and the supporting clamp 8, the action is stopped.

Then the lifting cylinder 29 of the clamp spring press-mounting device 3 drives the lifting seat 30 to move upwards for a certain distance, then the push-pull cylinder 31 drives the assembly sliding seat 32 to move towards the workpiece, when the guide sleeve 34 clamped by the sleeve clamping jaw cylinder 33 on the assembly sliding seat 32 moves to the upper part of the spline shaft, the push-pull cylinder 31 stops acting, and then the lifting cylinder 29 drives the lifting seat 30 to move downwards for a certain distance, so that the guide sleeve 34 is sleeved on the spline shaft.

After the guide sleeve 34 is sleeved on the spline shaft, the feeding cylinder 42 of the clamp spring feeding mechanism 38 drives the feeding push plate 43 to push the clamp spring at the bottom of the charging barrel 40 to the position of the clamping opening 44 along the guide chute 41, and then the feeding push plate 43 resets. Then, the rotating cylinder 36 rotates the clamp spring jaw cylinder 37 to correspond to the clamp spring on the clamping opening 44, and the clamp spring jaw cylinder 37 acts to clamp the clamp spring. Then, the rotating cylinder 36 drives the circlip jaw cylinder 3 to rotate and reset, and the circlip clamped by the circlip jaw cylinder 37 is located above the guide sleeve 34. Then, the pulling cylinder 35 drives the clamp spring to move downwards through the rotating cylinder 36 and the clamp spring jaw cylinder 37, so that the clamp spring is sleeved on the guide sleeve 34 and then resets.

After the clamp spring is sleeved on the guide sleeve 34, the press-fitting cylinder 46 acts to drive the press-fitting sleeve 47 to move downwards; the clamp spring is pushed to move downwards along the surface of the guide sleeve 34 in the downward movement process of the press-fitting sleeve 47; in this process, the sleeve gripper cylinder 33 releases the press-fitting sleeve 47, and the push-pull cylinder 31 moves the assembly carriage 32 rearward, so that the sleeve gripper cylinder 33 is out of contact with the press-fitting sleeve 47. The purpose of this action of the sleeve gripper cylinder 33 is to avoid the problem of the press-fitting sleeve 47 coming into contact with the jaws of the sleeve gripper cylinder 33 during its downward movement.

In the above process, when the press-fitting sleeve 47 moves downwards to push the snap spring to move along the surface of the guide sleeve 34 to the end of the guide sleeve, the snap spring retracts under the action of its own elasticity and is snapped into the fitting position of the spline shaft of the workpiece. The press-fit sleeve 47 is then reset upwardly. The sleeve clamping jaw cylinder 33 is driven to reset by clamping and pressing the sleeve 47 under the cooperation of the push-pull cylinder 31, the assembly slide 32 and the lifting cylinder 29. And the clamp spring press-mounting device 3 completes the assembly work of the clamp spring.

In the process of downwards moving the press-fitting sleeve 47 to extrude the spline shaft, after the spline shaft is pressed, the floating plate 15 is driven by a workpiece to overcome the elasticity of the buffer spring 16 and then downwards move; when the step surface on the spline shaft is abutted against the limiting clamping groove 49 of the limiting clamping plate 48, the workpiece stops moving downwards, and the spline shaft is kept fixed with the limiting clamping plate 48 under the supporting action of the limiting clamping plate; the press-fit sleeve 47 then snaps the snap spring into the assembly position of the spline shaft with the guide sleeve 34.

After the clamp spring press-mounting device 3 finishes the assembly work of the clamp spring, the longitudinal cylinder 7 works to drive the longitudinal sliding plate 6 to enable the longitudinal sliding plate to drive the assembled workpiece to move to a position close to the outer part of the rack 1 through the supporting clamp 8, then the assembled workpiece is taken down and a new workpiece is mounted, and the pull shaft and clamp spring assembling device of the automobile pipe column can enter the next working cycle.
