Abstract
The utility model discloses an auxiliary clamping mechanism for cylindrical lathe cutting, which comprises a clamping sleeve (1) for sleeving a machined moving bolt, wherein the clamping sleeve (1) is coaxially provided with an annular lubricating oil tank (2), the bottom surface of the lubricating oil tank (2) is in running fit with the end face of a center annularly arranged on a centre rest of a turning lathe, one end of the clamping sleeve (1) is at least provided with two regulating rods (3) which can be screwed in and out, and the regulating rods (3) are arranged on the same cross section of the clamping sleeve (1) and annularly and uniformly distributed along the outer peripheral surface of the clamping sleeve (1). The auxiliary clamping mechanism can regulate the coaxiality of the machined moving bolt, and can clamp the machined moving bolt so as to achieve a supporting effect.
Description
Technical field
The utility model relates to a kind of turning auxiliary clamp mechanism, is specifically a kind of auxiliary clamp mechanism that is used in when in the marine diesel cylinder, the motion bolt carries out turning 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 2.7～3m 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 gripping sleeve, this gripping sleeve forms the holes for clamping that gripping sleeve and processed motion bolt synchronous are rotated, the coaxial lubricating oil sump that is provided with ring-type also on this gripping sleeve, the end face of the thimble that arranges ringwise on the bottom surface of this lubricating oil sump and lathe center frame forms and is rotatably assorted.After this auxiliary clamp mechanism is clamped in lathe center frame, under the effect of lubricating oil, the end face of the thimble that arranges along annular on lathe center frame forms with the bottom surface of lubricating oil sump and is rotatably assorted, thereby make gripping sleeve rotatably be clamped on lathe center frame, this auxiliary clamp mechanism utilizes the setting of lubricating oil sump can realize support to processed motion bolt, simultaneously processed motion bolt is freely rotated.But in actual use, applicant's discovery, when turning, the motion bolt that always rotates continuously can produce vibration, adds that the length of motion bolt itself is longer, and along with the prolongation of process time, the coaxiality error of motion bolt is larger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of axiality of regulating processed motion bolt for above-mentioned the deficiencies in the prior art, makes the satisfactory turning auxiliary clamp mechanism of axiality of processed motion bolt.
For solving the problems of the technologies described above, turning auxiliary clamp mechanism 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, the coaxial lubricating oil sump that is provided with ring-type also on described gripping sleeve, the end face of the thimble that arranges ringwise on the bottom surface of described lubricating oil sump and lathe center frame forms and is rotatably assorted, but an end of described gripping sleeve is provided with the adjusting rod of two precessions or back-out at least, and described adjusting rod is positioned on the same cross section of gripping sleeve and to form annular along the outer circumference surface of gripping sleeve uniform.
The quantity of described adjusting rod is four, and these four adjusting rods are made by stay bolt, and described gripping sleeve is provided with the screwed hole that matches with stay bolt.
the beneficial effects of the utility model are: turning auxiliary clamp mechanism of the present utility model is provided with adjusting rod because of the end at gripping sleeve, add that adjusting rod is positioned on the same cross section of gripping sleeve and form annular along the outer circumference surface of gripping sleeve uniform, like this by precession or back-out adjusting rod, just can regulate the axiality that is sleeved on the processed motion bolt in gripping sleeve, thereby the axiality of the processed motion bolt of effective guarantee is within allowed band, simultaneously by the precession adjusting rod, make the outer circumference surface that the end face of adjusting rod presses processed motion bolt just can fastening processed motion bolt, thereby gripping sleeve and processed motion bolt synchronous are rotated.
As improvement, the quantity of described adjusting rod is four, these four adjusting rods are made by stay bolt, described gripping sleeve is provided with the screwed hole that matches with stay bolt, four radical amounts are preferred, the axiality of the processed motion bolt after more can effective guarantee regulating is in allowed band, and stay bolt can directly be bought and cost is low.
Description of drawings
Accompanying drawing is the structural representation of the utility model turning auxiliary clamp mechanism.
Shown in the utility model figure:
1, gripping sleeve, 2, lubricating oil sump, 3, adjusting rod.
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, turning auxiliary clamp mechanism of the present utility model comprises be used to the gripping sleeve 1 that is set with processed motion bolt.The coaxial lubricating oil sump 2 that is provided with ring-type also on described gripping sleeve 1, the end face of the thimble that arranges ringwise on the bottom surface of described lubricating oil sump 2 and lathe center frame forms and is rotatably assorted.But an end of described gripping sleeve 1 is provided with the adjusting rod 3 of two precessions or back-out at least, and described adjusting rod 3 is positioned on the same cross section of gripping sleeve 1 and to form annular along the outer circumference surface of gripping sleeve 1 uniform.
In the present embodiment, the quantity of described adjusting rod 3 is four, and these four adjusting rods 3 are made by stay bolt, and described gripping sleeve 1 is provided with the screwed hole (not shown) that matches with stay bolt.
Certainly, in allowed band, the other end of described gripping sleeve 1 also can be provided with same adjusting rod for the further axiality that ensures processed motion bolt, and concrete structure sees accompanying drawing for details.
After the utility model arranged adjusting rod, the axiality that can regulate processed motion bolt on the one hand can clamp fastening processed motion bolt on the other hand, so that gripping sleeve and processed motion bolt synchronous rotate.
