Abstract

The invention discloses an auxiliary clamping mechanism which comprises a clamping sleeve (1) and a ball bearing (2), wherein the clamping sleeve (1) is used for enabling a machined motion bolt to be sleeved and installed, and the ball bearing (2) is installed on the clamping sleeve (1). The inner ring of the ball bearing (2) is tightly matched with the outer circumferential surface of the clamping sleeve (1). A front limiting ring (3) and a rear limiting ring (4) are further arranged on the clamping sleeve (1), wherein the front limiting ring (3) and the rear limiting ring (4) are used for axially limiting the ball bearing (2). The two ends of the clamping sleeve (1) are respectively provided with at least two adjusting levers (5) capable of being screwed in or screwed out. The adjusting levers (5) located at the same end of the clamping sleeve (1) are located on the same cross section of the clamping sleeve (1) and annularly and evenly distributed along the outer circumferential face of the clamping sleeve (1). The auxiliary clamping mechanism can adjust the coaxiality of the machined motion bolt and enable the coaxiality of the machined motion bolt to meet requirements.

Description

Auxiliary clamp mechanism
Technical field
The present invention relates to a kind of auxiliary clamp mechanism, specifically is a kind of to being used in the auxiliary clamp mechanism on the lathe centre frame in the marine diesel cylinder during motion bolt turning.
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 usefulness, this connector also moves with piston, piston rod when playing the connection effect, is the motion bolt so be commonly called as in the industry.
Because the length of motion bolt has reached the length of 10m, so on lathe, during turning, need have supporting mechanism that the motion bolt is supported.At present, though lathe carries passive lathe centre frame, but the lathe centre frame of the type is when the supporting movement bolt, all be the outer circumference surface that presses the motion bolt by a plurality of thimbles of circle distribution on the lathe centre frame, when adding lathe to motion bolt turning, the motion bolt is with the lathe main axis rotation, the a plurality of thimbles that press with the outer circumference surface of motion bolt on the actionless like this lathe centre 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 the industry, thereby the motion bolt can't normally be rotated, can't carry out normal turning processing.
So the applicant has invented a kind of auxiliary clamp mechanism that is specifically designed on the lathe centre frame, should auxiliary clamp mechanism comprise gripping sleeve and the ball bearing that is installed on the gripping sleeve, wherein gripping sleeve is used for the processed motion bolt of suit and can rotates synchronously with processed motion bolt, and after should assisting clamp mechanism to be clamped in the lathe centre frame, the thimble that lathe centre frame upper edge annular arranges then presses the outer ring of ball bearing, thereby ball bearing firmly is clamped on the lathe centre frame, should auxiliary clamp mechanism utilize ball bearing can realize support to processed motion bolt simultaneously processed motion bolt freely being rotated.But in actual use, the applicant finds that when turning, the motion bolt that rotates continuously can produce vibration always, 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 bigger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of axiality of regulating processed motion bolt at above-mentioned the deficiencies in the prior art, makes the satisfactory auxiliary clamp mechanism of axiality of processed motion bolt.
For solving the problems of the technologies described above, auxiliary clamp mechanism of the present invention is by the following technical solutions: comprise for the gripping sleeve of the processed motion bolt of suit and be installed in ball bearing on the 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 back spacing ring for the axial limiting ball bearing on the described gripping sleeve, but the two ends of described gripping sleeve are provided with the adjusting rod of two precessions or back-out respectively at least, and the adjusting rod that is positioned at the same end of gripping sleeve all 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 that is positioned at the adjusting rod of the same end of gripping sleeve 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 invention has the beneficial effects as follows: but auxiliary clamp mechanism of the present invention is because being provided with the adjusting rod of two precessions or back-out respectively at least at the two ends of gripping sleeve, add that the adjusting rod that is positioned at the same end of gripping sleeve all 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 the gripping sleeve, thereby ensure that effectively the axiality of processed motion bolt 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 are rotated synchronously.
As improvement, the quantity that is positioned at the adjusting rod of the same end of gripping sleeve 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, more can effectively ensure the axiality of the processed motion bolt after the adjusting in allowed band, and stay bolt can be bought directly and cost is low.
Description of drawings
Accompanying drawing is the structural representation of the auxiliary clamp mechanism of the present invention.
Shown in the figure of the present invention:
1, gripping sleeve, 2, ball bearing, 3, the front limit ring, 4, the back spacing ring, 5, adjusting rod.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in the figure, auxiliary clamp mechanism of the present invention comprises gripping sleeve 1 and the ball bearing 2 that is installed on the gripping sleeve 1 for the processed motion bolt of suit.The outer circumference surface close-fitting of the inner ring of described ball bearing 2 and gripping sleeve 1 also is provided with front limit ring 3 and back spacing ring 4 for axial limiting ball bearing 2 on the described gripping sleeve 1.
But the two ends of described gripping sleeve 1 are provided with the adjusting rod 5 of two precessions or back-out respectively at least, and the adjusting rod 5 that is positioned at gripping sleeve 1 same end 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 that is positioned at the adjusting rod 5 of gripping sleeve 1 same end is four, and this four adjusting rods 5 are made by stay bolt, and described gripping sleeve 1 is provided with the screwed hole (not shown) that matches with stay bolt.
The setting of adjusting rod of the present invention, the axiality that can regulate processed motion bolt can clamp fastening processed motion bolt, on the other hand so that gripping sleeve and processed motion bolt rotate synchronously on the one hand.
