Description
Technical field
The utility model relates to the auxiliary clamp mechanism on a kind of lathe center frame, is specifically a kind of auxiliary clamp mechanism that is used in during motion bolt turning in to the marine diesel cylinder on lathe center frame.
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, and two ends respectively are provided with the screw thread that connects use, this connector also moves with piston, piston rod when playing connection function, is the motion bolt therefore be commonly called as in industry.
Reached the length of 10m because of the length of motion bolt, therefore during turning, need to have supporting mechanism that the motion bolt is supported on lathe.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 thimbles 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 thimbles 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.
therefore the applicant has invented a kind of auxiliary clamp mechanism that is specifically designed on lathe center frame, this auxiliary clamp mechanism comprises that gripping sleeve and axial location are arranged on the ball bearing on gripping sleeve, wherein gripping sleeve is used for being set with processed motion bolt and can rotates with processed motion bolt synchronous, after this auxiliary clamp mechanism is clamped in lathe center frame, the thimble that arranges along annular on lathe center frame presses the outer ring of ball bearing, thereby make ball bearing firmly be clamped on lathe center frame, this auxiliary clamp mechanism utilizes ball bearing can realize support to processed motion bolt, simultaneously processed motion bolt is freely rotated.But applicant's discovery, the axial cutting force that produces in actual turning process is larger, and this axial cutting force can part be loaded on auxiliary support mechanism by processed motion bolt, therefore this just needs auxiliary support mechanism to have stronger load intensity.
Summary of the invention
Technical problem to be solved in the utility model is the auxiliary clamp mechanism that provides for above-mentioned the deficiencies in the prior art on a kind of lathe center frame with stronger load intensity.
for solving the problems of the technologies described above, auxiliary clamp mechanism on lathe center frame of the present utility model is by the following technical solutions: comprise be used to the gripping sleeve that is set with processed motion bolt and rotates with processed motion bolt synchronous, be arranged on the ball bearing on gripping sleeve, the outer circumference surface close-fitting of the inner ring of described ball bearing and gripping sleeve, also be provided with front limit ring and rear spacing ring for the axial limiting ball bearing on described gripping sleeve, also be provided with the load baffle ring on the outer circumference surface of described gripping sleeve, the rear end face of described load baffle ring and rear spacing ring is affixed, described load baffle ring is vertical with gripping sleeve.
Described load baffle ring is welded on the outer circumference surface of gripping sleeve.
The thickness of described load baffle ring is 1.5～3 times of thickness of rear spacing ring.
The external diameter of described load baffle ring is 1 ∕ 4～3 ∕ 4 of the external diameter of rear spacing ring.
The beneficial effects of the utility model are: the auxiliary clamp mechanism on lathe center frame of the present utility model is because being provided with the load baffle ring on the outer circumference surface of gripping sleeve, and the rear end face of this load baffle ring and rear spacing ring is affixed, the load baffle ring that arranges so just can bear the axial cutting force that processed motion bolt produces when the car turning, to increase the load intensity of rear spacing ring and whole auxiliary clamp mechanism.
As improvement, described load baffle ring is welded on the outer circumference surface of gripping sleeve, is welded to connect more firmly, more can bear axial cutting force.
As preferably, the thickness of described load baffle ring is 1.5～3 times of thickness of rear spacing ring, and this thickness is a preferable range value, is effectively improving under the prerequisite of load intensity, is unlikely to again blocked up and causes waste.
As improvement, the external diameter of described load baffle ring is 1 ∕ 4～3 ∕ 4 of the external diameter of rear spacing ring, mainly concentrates on the root place of rear spacing ring because of cutting force, can not only ensure like this load effect of load baffle ring, is unlikely to again external diameter excessive and cause waste.
