Problems solved by technology

[0002] At present, domestic manufacturers of marine cylinder liners usually use one end with three claws to clamp the inner hole for rough machining, and the other end uses a thimble to cover the end face of the cylinder liner. The thimble attached to the machine tool generally uses a radial ball bearing and a pla

Embodiment Construction

[0010] Install plane bearing 2, single row tapered roller bearing 5, bushing 4 and single row tapered roller bearing 8 on the ejector rod 1, and then install bushing 3 on plane bearing 2, single row tapered roller bearing 5, single row tapered roller bearing On the outer circle of the sub-bearing 5 and the outer circle of the push rod 1, then lock the cap 7, and then screw the bulkhead 6 and the shaft sleeve 3. When the bulkhead is in contact with the bulkhead 6, the shaft sleeve 3 and the bulkhead 6 rotate around the push rod as a whole.

Abstract

The invention discloses a thimble for roughly turning an air cylinder sleeve for a ship. Two single-row tapered roller bearings for bearing heavy weight are mounted in front of the thimble; and a plane bearing for bearing a great cutting force is mounted at the back of the thimble. Therefore, the thimble has high manufacturing precision, accuracy for positioning and long service life. The invention has the benefits as follows: due to the use of the thimble, the service life of the thimble for roughly turning the air cylinder sleeve for the ship is prolonged and the difference between the wall thickness of the inner circle and the wall thickness of the excircle of the air cylinder sleeve can be ensured.

Description

technical field [0001] The invention relates to a jig for rough turning of a cylinder liner, which is especially suitable for batch production of marine cylinder liners. Background technique [0002] At present, domestic manufacturers of marine cylinder liners usually use one end with three claws to clamp the inner hole for rough machining, and the other end uses a thimble to cover the end face of the cylinder liner. The thimble attached to the machine tool generally uses a radial ball bearing and a plane bearing to bear the axial Force and cutting force, due to the heavy marine cylinder liner and the large cutting force of the outer circle of rough turning, the weight and cutting force of the radial ball bearing and plane bearing of the thimble are generally small, and the thimble is easy to be damaged. Contents of the invention [0003] In order to overcome the deficiency of common thimbles, the present invention provides a thimble for cylinder liners used in rough vehic...
