Abstract
The utility model discloses a lathe center frame used for supporting a moving bolt in a marine diesel engine cylinder, comprising a lathe center frame body (1), wherein a clamping ring body (2) is formed at the upper end of the lathe center frame body (1), a plurality of ejector rods (3) with tail ends stretching into the inner ring (2.1) of the clamping ring body (2) are distributed on the clamping ring body (2) in a circumferential way, the tail ends of the ejector rods (3) are provided with idler wheels (4), and the central axis of the idler wheels (4) are vertical to the ejector rods (3). The lathe center frame can support the moving bolt and can also enable the moving bolt to rotate, thus effectively guaranteeing the excircle machining of the blank of the moving bolt and the rough machining of the excircle of the moving bolt.
Description
Technical field
The utility model relates to the supporting mechanism on a kind of lathe, is specifically a kind of lathe center frame for supporting motion bolt in the marine diesel cylinder.
Background technology
At present, there is a kind of tonnage to reach the marine low speed diesel engine of 1850t, the connector that is used for connection piston and piston rod in the cylinder of this diesel engine generally adopts the high-quality special steel alloy to be made, integral body is cylindrical shape, two ends are provided with the screw thread that connects use, this motion connector also moves with piston, piston rod when playing connection function, is the motion bolt therefore be commonly called as in industry.
That have because of the length of this motion bolt is 2.7～3m, and what have has even reached 10m, therefore when utilizing lathe that the woollen of motion bolt is carried out Excircle machining or the motion bolt is carried out cylindrical roughing, need to have supporting mechanism that the motion bolt is supported.at present, although lathe carries passive lathe center frame, but the lathe center frame of the type is when the supporting movement bolt, all the outer circumference surface that presses the motion bolt by a plurality of push rods of circle distribution on lathe center frame, when adding lathe to motion bolt turning, the motion bolt rotates with the lathe main shaft, a plurality of push rods that press with the outer circumference surface of motion bolt on actionless like this lathe center frame just can tightly be clamped the motion bolt and the rotation of retardation motion bolt, so just form the state of killing that is commonly called as in industry, thereby the motion bolt can't normally be rotated, can't carry out normal turning processing.
The utility model content
Technical problem to be solved in the utility model be provide for above-mentioned the deficiencies in the prior art a kind of can be to the motion bolt woollen that carries out Excircle machining or the lathe center frame that is used for supporting motion bolt in the marine diesel cylinder that supports carrying out the rough machined motion bolt of cylindrical.
For solving the problems of the technologies described above, the lathe center frame that the utility model be used for to support motion bolt in the marine diesel cylinder is by the following technical solutions: comprise the lathe center frame body, the upper end of this lathe center frame body forms the clamping circle body, be on this clamping circle body and be evenly distributed in many ends and extend into the push rod that clamps in the circle body inner ring, the end of described push rod is equipped with roller, and the central axis of described roller is vertical with push rod.
The end of described push rod is equipped with roller and refers to, the end of described push rod is provided with the roller bearing vertical with push rod, and a ball bearing is installed on this roller bearing, and described roller is arranged on the outer ring of ball bearing.
The beneficial effects of the utility model are: the lathe center frame for supporting motion bolt in the marine diesel cylinder of the present utility model arranges roller by the end at push rod, like this after the motion bolt sleeve is loaded on lathe center frame, roller forms to roll with the outer circumference surface of motion bolt and coordinates, lathe center frame both can support the motion bolt like this, can make again motion bolt normal rotation, can make the motion bolt carry out normal woollen Excircle machining and roughing.
As improvement, the end of described push rod is equipped with roller and refers to, the end of described push rod is provided with the roller bearing vertical with push rod, one ball bearing is installed on this roller bearing, described roller is arranged on the outer ring of ball bearing, roller is arranged on push rod by ball bearing, and compact conformation and roller rotate flexibly.
Description of drawings
Accompanying drawing is the main TV structure schematic diagram that the utility model is used to support the lathe center frame of motion bolt in the marine diesel cylinder.
Shown in the utility model figure:
1, lathe center frame body, 2, clamp circle body, 2.1, inner ring, 3, push rod, 4, roller, 5, roller bearing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, the lathe center frame for supporting motion bolt in the marine diesel cylinder of the present utility model comprises lathe center frame body 1.The upper end of this lathe center frame body 1 forms and clamps circle body 2, is on this clampings circle body 2 to be evenly distributed in many ends and to extend into and clamp the circle body 2 interior push rods 3 of inner rings 2.1.The end of described push rod 3 is equipped with roller 4, and the central axis of described roller 4 is vertical with push rod 3.In the present embodiment, the quantity of described push rod 3 is 4, therefore the quantity of described roller 4 is 4.
In the present embodiment, the end of described push rod 3 is equipped with roller 4 and refers to, the end of described push rod 3 is provided with the roller bearing vertical with push rod 35, and a ball bearing (not shown) is installed on this roller bearing 5, and described roller 4 is arranged on the outer ring of ball bearing.
Lathe center frame utilization for supporting motion bolt in the marine diesel cylinder of the present utility model realize on the push rod of lathe center frame, the mode of roller being installed be sleeved on lathe center frame on the motion bolt form to roll and coordinate, lathe center frame both can support the motion bolt like this, the motion bolt is rotated, effective guarantee the Excircle machining of motion bolt woollen and the cylindrical roughing of motion bolt.
Claims (2)
1. lathe center frame that be used for to support motion bolt in the marine diesel cylinder, comprise lathe center frame body (1), it is characterized in that: the upper end of this lathe center frame body (1) forms and clamps circle body (2), be on this clamping circle body (2) and be evenly distributed in many ends and extend into the push rod (3) that clamps in circle body (2) inner ring (2.1), the end of described push rod (3) is equipped with roller (4), and the central axis of described roller (4) is vertical with push rod (3).
