specific Embodiment approach

[0032] When in use, the C-shaped crown spring 3 is automatically oriented and arranged under the action of the vibrating plate 1, and is transported to the feeding chute 12 on the top of the feeding slider 11 under the action of the linear feeder 2. When the positioning sensor 19 detects the C-shaped When the crown springs 3 enter the feeding trough 12 one by one, the control pushes the cylinder 10 to push the feeding slider 11, and then drives the push block 13 to push the C-shaped crown springs 3 horizontally onto the positioning platform 4 to realize separation one by one; at this time, the mechanical gripper 15. Mechanical gripper 2 6 clamps both sides of the C-shaped crown spring 3 on the positioning platform 4 under the action of the parallel jaw cylinder, and moves horizontally to the top of the three-jaw cylinder fixture 18 under the action of the rodless cylinder 16, Further, the vertical displacement of the parallel clamping cylinder 14 is adjusted by the three-axis c...

Abstract

The invention discloses a clamp for automatic assembly of a C-shaped crown spring. The clamp comprises a directional separating component and an automatic assembling component; a parallel clamping cylinder is used for driving a mechanical clamping claw I and a mechanical clamping claw II to clamp the two sides of a directionally-separated C-shaped crown spring; a mobile positioning mechanism is used for driving movement positioning of the parallel clamping cylinder; the sections of the mechanical clamping claw I and the mechanical clamping claw II are in a semicircular ring shape; the inner surface of one side of each clamping claw interface is provided with an arc-shaped flange; the distance from the arc-shaped flange on the mechanical clamping claw I to the corresponding clamping claw interface is smaller than that from the arc-shaped flange on the mechanical clamping claw II to the corresponding clamping claw interface; and under the effects of the flanges, the two sides of an opening of the C-shaped crown spring are not abutted but are overlapped to a certain extent. The clamp disclosed by the invention is simple in structure, convenient to use and high in automation degree, solves the problem of abutting of the opening of the C-shaped crown spring by a flange design on the mechanical clamping claws, realizes an efficient and stable automatic assembly process, saves labor and cost and has good economical and practical values.

Description

technical field [0001] The invention relates to a fixture for automatic assembly of a C-shaped crown spring, which is suitable for C-shaped micro-structural parts that are difficult to be assembled automatically, and belongs to the technical field of automatic assembly fixtures. Background technique [0002] At present, the known C-shaped crown springs use ordinary jaws in the process of automatic assembly. However, when the ordinary jaws clamp the C-shaped crown spring products, it is often caused by the problem of butt joints at the openings during assembly. It is more difficult, and the crown spring may not be assembled or even damaged. Therefore, the automatic assembly process of the C-shaped crown spring still faces some technical difficulties. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a fixture for automatic assembly of C-shaped crown springs, which has the char...
