Abstract
The utility model discloses an auxiliary supporting mechanism for a thread forming machine. The auxiliary supporting mechanism comprises a supporting table (1), a limiting box (2) spliced by four side plates, two supporting seats (3) located in the limiting box (2), and idler wheels (4) which are mounted on the two supporting seats (3) respectively and rotatably; the auxiliary supporting mechanism further comprises a bottom plate (5) and two parallel guide rails (6) which are arranged on the supporting table (1) and extend along an axial feeding direction of a movable bolt to be machined; the limiting box (2) is fixedly arranged on the bottom plate (5); the bottom plate (5) is provided with a fixed shaft (7) being vertical to the guide rails (6); limiting idler wheels (8) which are in rolling match with the guide rails (6) are mounted on the two ends of the fixed shaft (7) rotatably. The mechanism disclosed by the utility model can do axial feeding movement with the movable bolt to be machined.
Description
Technical field
The utility model relates to a kind of passive mechanism, is specifically a kind of thread forming machine auxiliary support mechanism.
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, what have has even reached 10m, the screw thread that adds motion bolt two ends is that minute successively extrusion modling (namely first goes out screw thread with end extrusion modling on thread forming machine of motion bolt, the recycling crane, after the motion bolt is turned round again extrusion modling go out other end screw thread.), therefore when extrusion modling campaign bolt threaded one end, the other end (being free end) need have supporting mechanism that the motion bolt is supported, so that the motion bolt is completed the extrusion modling of screw thread smoothly.
Therefore the applicant has invented a kind of auxiliary support mechanism that is specifically designed to the supporting movement bolt, this auxiliary support mechanism rolls with the motion bolt by two rollers and contacts, thereby realize the support to the motion bolt, but when the screw thread of extrusion modling campaign bolt, the motion bolt is made axial feed motion, auxiliary support mechanism still keeps original position, keeps like this auxiliary support mechanism of original position to greatly reduce the speed of motion bolt axial feed, is not easy to the extrusion modling of motion bolt thread.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of for above-mentioned the deficiencies in the prior art can make the thread forming machine auxiliary support mechanism of axial feed motion together with the motion bolt.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: the position-limited box that comprises support desk, is spliced by four blocks of side plates, be positioned at two supporting seats of position-limited box, be rotatably installed in roller on two supporting seats respectively, two closed slides that it also comprises a base plate and is arranged on support desk and extends to direction of feed motion along the processed bolt shaft of moving, described position-limited box is fixed on base plate, described base plate is provided with the fixed axis vertical with guide rail, and the two ends of described fixed axis are rotatablely equipped with the limited roller that rolls and coordinate with guide rail.
The quantity of described fixed axis is two, and these two fixed axis are parallel to each other, and these two fixed axis one in front and one in back are arranged on respectively the bottom of base plate, and these two fixed axis all are connected with base plate by connecting rod.
Described limited roller is made of the main wheel that coordinates with the guide rail rolling and the position-limited wheel that is positioned at main wheel one side.
The beneficial effects of the utility model are: thread forming machine auxiliary support mechanism of the present utility model is by the setting of limited roller and guide rail, like this when the screw thread of extrusion modling campaign bolt, limited roller rolls the effect that coordinates with guide rail under, auxiliary support mechanism just can be made axial feed motion with the motion bolt, the feed motion speed of motion bolt is accelerated, be convenient to the screw thread extrusion modling of motion bolt.
As improvement, the quantity of described fixed axis is two, and these two fixed axis are parallel to each other, and these two fixed axis one in front and one in back are arranged on respectively the bottom of base plate, and these two fixed axis all are connected with base plate by connecting rod, make the auxiliary support mechanism even running.
As further improvement, described limited roller is made of the main wheel that coordinates with the guide rail rolling and the position-limited wheel that is positioned at main wheel one side, and the limited roller structural design is ingenious, and is spacing reliable.
