[0045] Example 1:

[0046] As shown in the drawings, the automatic assembly equipment for shaft and conical spring of the present embodiment, one end of the shaft 3 is provided with a taper surface 31, and the equipment comprises a clamping mechanism 2, a moving mechanism 1, a radial limiting structure 5 and an axial limiting mechanism 6. Figure 1 The clamping mechanism 2 is used for clamping the shaft 3;

[0047] The moving mechanism 1 is used for driving the clamping mechanism 2 to move;

[0048] The radial limiting structure 5 is located below the clamping mechanism 2, and the radial limiting structure 5 is provided with a groove 53, the groove 53 matches the large end diameter of the conical spring 4, and is used for limiting the radial position of the conical spring 4, and the bottom of the groove 53 is provided with a through hole 55;

[0049] The axial limiting mechanism 6 comprises a pair of floating blocks 611 arranged oppositely, the two floating blocks 611 are coupled with the groove 53, and the axial position of the conical spring 4 is limited from the lower part of the large end of the conical spring 4, the gap between the two floating blocks 611 is a movable clamping hole 612, and the movable clamping hole 612 is coaxial with the through hole 55;

[0050] The axial limiting mechanism 6 comprises a pair of floating blocks 611 arranged oppositely, the two floating blocks 611 are coupled with the groove 53, and the axial position of the conical spring 4 is limited from the lower part of the large end of the conical spring 4, the gap between the two floating blocks 611 is a movable clamping hole 612, and the movable clamping hole 612 is coaxial with the through hole 55;

[0051] In this process, the conical surface 31 of the shaft 3 passes through the small end of the conical spring 4, the movable locking hole 612 and the through hole 55 in sequence. During the process of the small end of the conical spring 4 being opened and fitted onto the outside of the shaft 3, the floating support block 611 remains in contact with the small end of the conical spring 4, and the movable locking hole 612 contacts the outer peripheral surface of the shaft 3.

[0052] The conical spring 4 can be fed manually or automatically. Simply place the conical spring 4 in the groove 53 and on the floating support block 611.

[0053] The clamping mechanism 2 and the moving mechanism 1 can have various structures, as long as they can realize the automatic movement of the shaft 3, and at least ensure that the shaft 3 has the function of moving along the through hole 55 and the movable locking hole 612.

[0054] In one specific embodiment, the moving mechanism 1 includes a transverse moving mechanism 11, a longitudinal moving mechanism 12 is installed at the moving end of the transverse moving mechanism 11, and a clamping mechanism 2 is installed at the moving end of the longitudinal moving mechanism 12.

[0055] In one specific embodiment, the unloading and feeding processes share a common clamping mechanism 2.

[0056] The working process of the automatic assembly equipment for shaft 3 and conical spring 4 is as follows:

[0057] First, place the conical spring 4 in the groove 53;

[0058] Then, after the moving mechanism 1 drives the clamping mechanism 2 to clamp the shaft 3 to be assembled with the conical spring 4, it continues to drive the shaft 3 to move toward the radial limiting structure 5 and the axial limiting mechanism 6.

[0059] Then, as Figure 6 As shown, the conical surface 31 of the shaft 3 passes through the small end of the conical spring 4, the movable retaining hole 612 and the through hole 55 in sequence. The small end of the conical spring 4 is smaller than the diameter of the cylindrical section of the shaft 3, and the diameter of the through hole 55 is larger than the diameter of the cylindrical section of the shaft 3. Since the large end of the conical spring 4 is limited, the conical spring 4 is compressed until it becomes flat. As the shaft 3 moves, the small end of the conical spring 4 is opened up and fitted onto the cylindrical section of the conical spring 4 until the small end of the conical spring 4 is inserted into the limiting groove 32.

[0060] During the above process, the movable locking hole 612 is always in contact with the outer wall of the shaft 3. The cross-sectional dimensions of the movable locking hole 612 change with the change of the contact position with the shaft 3, ensuring that the floating support block 611 is in contact with the small end of the conical spring 4, axially limiting the small end, forcing the small end to be pushed open during the sliding process on the conical surface 31. At the same time, the floating support block 611 also limits the large end of the conical spring 4, thereby achieving axial limitation of the entire conical spring 4.

[0061] The mechanical hand driving shaft piece 3 is moved by the clamping mechanism 2 and the moving mechanism 1 to replace manual operation, the conical spring 4 is radially limited by the radial limiting structure 5, the positioning and feeding of the conical spring 4 are facilitated, the small end of the conical spring 4 is axially limited by the axial limiting mechanism 6 in the process that the shaft piece 3 is inserted into the conical spring 4, the axial limiting mechanism 6 avoids the shaft piece 3 together with the radial limiting structure 5, the position of the small end of the conical spring 4 on the shaft piece 3 is changed, the automatic assembly of the shaft piece 3 and the conical spring 4 is realized, the labor intensity is reduced, and the assembly efficiency is improved.

[0063] The first finger air cylinder 62 drives the relative movement of the first clamping claw 61 to form the movable clamping hole 612, the size of the movable clamping hole 612 first ensures that the conical surface 31 can extend into the movable clamping hole 612, the self-function characteristics of the first finger air cylinder 62 are utilized to realize that the movable clamping hole 612 is in contact with the outer periphery of the shaft piece 3 at any time, and then the floating supporting block 611 can axially limit the small end of the conical spring 4 at any time, in the process that the movable clamping hole 612 and the shaft piece 3 axially relatively displace, the conical spring 4 is sleeved on the shaft piece 3 and slides to the cylindrical segment.

The two oppositely arranged V-shaped grooves form the movable clamping hole 612, meet the condition of matching the shape of the shaft piece 3, reduce the area of the contact part of the movable clamping hole 612 and the shaft piece 3, and reduce the friction force in the relative movement process of the two.
