Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 2, the utility model discloses an automatic positioning mechanism that aligns, including work piece positioning seat 1, set up the spout in work piece positioning seat 1, the built-in steel ball 2 that can be gliding about in the spout and the spring 4 of installing in the 2 bottoms of steel ball that is equipped with of spout for match with the location keyway of work piece 3. When the positioning operation is executed, the workpiece 3 is moved to the position above the workpiece positioning seat 1 and then pressed downwards; when the workpiece 3 is not aligned accurately, the steel balls 2 are pressed into the sliding grooves; when the workpiece 3 is rotated and the workpiece 3 is aligned accurately, the steel ball 2 is pushed out by the elastic force of the spring 4, so that the steel ball is matched with the key groove of the workpiece 3 to finish alignment and positioning.
As shown in fig. 1, the automatic alignment positioning mechanism further comprises a parallel claw 7 for clamping the workpiece 3, a pushing cylinder 10 is arranged at the top of the parallel claw 7 for providing downward pushing force, and a rotating cylinder 9 is connected between the parallel claw 7 and the pushing cylinder 10 for providing power for rotating and positioning the workpiece 3.
When the clamping device is used, the parallel claws 7 clamp a workpiece 3 and then move to the position above the workpiece positioning seat 1; at the moment, the ejection cylinder 10 works to push the workpiece 3 down to the workpiece positioning seat 1; when the workpiece 3 is tightly attached to the workpiece positioning seat 1, the ejection cylinder 10 stops working, the rotary cylinder 9 starts working, the workpiece 3 rotates, when the workpiece 3 is accurately aligned, the steel ball 2 is pushed out by the elastic force of the spring 4 to be matched with the key groove of the workpiece 3, the rotary cylinder 9 stops working at the moment, and the whole alignment and positioning are completed.
The utility model also provides an improved technical proposal, in the improved technical proposal, three groups of chutes, steel balls 2 and springs 4 are arranged; three sets of chutes, steel balls 2 and springs 4 are preferably symmetrically arranged.
