Embodiment Construction
[0010] The friction welding machine oil-free bearing sleeve anti-slip clamping device includes an outer spring chuck 002 with one end outside the sleeve 001 and an inner spring chuck 003 with one end inside the sleeve 001. The inner and outer spring chucks ( 003, 002) are sleeve type, the end of the outer collet 002 sleeved outside the sleeve 001, and the end of the inner collet 003 sleeved inside the sleeve 001 are all tapered structures, and the tapered ends are divided into Four petals; the tapered end 021 of the outer collet 002 is sleeved in the piston rod sleeve of a hydraulic cylinder, the piston rod sleeve pushes the outer collet 002, and the tapered end 021 shrinks the clamping sleeve inward The outer surface of the cylinder; the inner spring chuck 003 is provided with a pull rod 004, the head of the pull rod 041 is a conical head matching the tapered end 031 of the inner spring chuck 003, and the end of the pull rod 004 is connected to another hydraulic cylinder, the ...

The invention provides an anti-slip clamping device for an oilless bearing sleeve of a friction welding machine, and relates to the field of welding for oilless bearings of friction welding machines. The anti-slip clamping device for the oilless bearing sleeve of the friction welding machine comprises an outer collet chuck and an inner collet chuck, wherein one end of the outer collet chuck is arranged outside the bearing sleeve in a sleeved mode, one end of the inner collet chuck is sleeved with the bearing sleeve, the inner collet chuck and the outer collet chuck are in a sleeve type, the end, sleeved with the bearing sleeve, of the inner collect chuck and the end, arranged outside the bearing sleeve in the sleeved mode, of the outer collet chuck are of a conical structure, and the conical end of the inner collet chuck and the conical end of the outer collet chuck are respectively at least divided into two pieces. The conical end of the outer collet chuck is sleeved with a piston rod sleeve of a hydraulic oil cylinder, the outer collet chuck is pushed and squeezed by the piston rod sleeve, and the conical end of the outer collet chuck shrinks inwards to clamp the outer surface of the bearing sleeve. A pull rod is arranged in the inner collet chuck, a conical head matched with the conical end of the inner collet chuck is arranged on the head of the pull rod, a hydraulic oil cylinder is connected to the tail end of the pull rod, and the conical end of the inner collet chuck is expanded outwards to clamp the inner surface of the bearing sleeve when the pull rod stretches out and draws back. The bearing sleeve is clamped reliably, no slip or damage occurs, the qualified rate of products is improved, clamping time is short, efficiency is high, cost is reduced, and waste is avoided.
Description
technical field [0001] The invention relates to the field of friction welding machine oil-free bearing welding, in particular to a clamping device for a bearing sleeve. Background technique [0002] The bearing sleeve is formed by roll forming of a wear-resistant copper-based powder metallurgy thin steel plate plated on the inner wall. It is required that the inner hole and outer circle are not damaged when clamping. [0003] The existing similar products only clamp the outer circle of the sleeve, add a mandrel to the inner hole of the sleeve, and put a layer of non-slip sand skin in the inner hole. Because it is one-way clamping, its clamping effect is unreliable, and the sleeve often slips, causing damage to the clamp, scars on the product, and unqualified quality. And the clamping sleeve procedure is loaded down with trivial details, and the time is long, and efficient is low. Increase the cost and waste a lot of sand. Room for improvement.
