Abstract
The utility model relates to an elastic tip. The elastic tip consists of a tip body 1, a spring 2, a tip 3 and a socket 4. The tip body 1 is in threaded connection with the socket 4 so as to fix the spring 2 and the tip 3 in the socket 4. The compressed degree of the spring 2 absorbs impact of the machining precision of a short head of a crankshaft to crank throw machining and the machining precision of a long head of the crankshaft of a single cylinder diesel engine. Convenient and quick clamping can be realized by the elastic tip. Requirements on dimensional precision are easier to realize after the elastic tip is machined on a numerically controlled lathe, and the production efficiency is remarkably improved.
Description
Technical field
The utility model technology is the used centre with endlong movement of a kind of one-cylinder diesel machine crankshaft numerically controlled lathe Vehicle Processing.
Background technology
The one-cylinder diesel machine crankshaft is when utilizing the fine finishining of numerically controlled lathe march axial length, and the distance that requires to guarantee crank throw two outsides reaches certain dimension precision requirement, and the long trunnion of bent axle is to the axiality requirement of crankshaft two end simultaneously.Improper because of clamping method aborning, can not guarantee to reach above-mentioned two dimension precision requirement simultaneously.If adopt a folder one top clamping, utilize one end face location, three-jaw end face and the crank throw outside, can guarantee that crank throw two outboard shafts are to dimension precision requirement; But axiality requires to be difficult to guarantee; And strengthened clamping used non-cutting time, reduced working (machining) efficiency, increased operating personnel's the amount of labour; If adopt Double Tops mode clamping, the result is just in time opposite.Through researching and analysing, causing above-mentioned reasons of error is machining benchmark and design basis disunity.The utility model can utilize centre with endlong movement can realize clamping quickly and easily, being prone to reach desired dimension precision requirement after the processing on the numerically controlled lathe, has obviously improved production efficiency.
Summary of the invention
The purpose of the utility model is to utilize centre with endlong movement can realize clamping quickly and easily, being prone to reach desired dimension precision requirement after the processing on the numerically controlled lathe, has obviously improved production efficiency.
The technical scheme that the utility model adopts is: it is by top body, spring, top and connect cover and form.Top body is threaded with connecing cover utilization, in top and spring are fixed on.When carrying out clamping; The centre bore of one-cylinder diesel machine crankshaft brachycephaly has spring by top jack-up between the top and top body, makes the end face and crank throw one side contacts that connect cover; The difference of utilizing spring to be compressed degree has changed the influence of the long head of bent axle being processed because of the precision of bent axle brachycephaly processing; Can realize clamping quickly and easily,, obviously improve production efficiency being prone to reach desired dimension precision requirement after the processing on the numerically controlled lathe.
During the utility model work; Centre with endlong movement cooperates with the tailstock center of numerically controlled lathe, and the one-cylinder diesel machine crankshaft can be realized clamping quickly and easily, and the precision of one-cylinder diesel machine crankshaft brachycephaly processing is absorbed by the centre with endlong movement inner spring; No longer have influence on the processing of the long head of bent axle; The location of the long head processing of bent axle is realized by the cover side that connects of centre with endlong movement, being prone to reach desired dimension precision requirement after the processing on the numerically controlled lathe, has obviously been improved production efficiency.
The beneficial effect of the utility model is: can realize clamping quickly and easily, being prone to reach desired dimension precision requirement after the processing on the numerically controlled lathe, obviously improve production efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model
Among Fig. 1,1, top body; 2, spring; 3, top; 4, connect cover.
The specific embodiment
The utility model is threaded with connecing cover 4 utilizations by top body 1, spring 2 and top 3 is fixed on connect in the cover 4.Centre with endlong movement and numerically controlled lathe tailstock center can be realized clamping quickly and easily with the one-cylinder diesel machine crankshaft; Be about to one-cylinder diesel machine crankshaft jack-up; Because be the rigidity contact during traditional Double Tops point clamping, the processing precision direct influence of one-cylinder diesel machine crankshaft brachycephaly is to the machining accuracy of the long head of one-cylinder diesel machine crankshaft and the machining accuracy of crank throw both sides; Utilize the utility model; Avoided the top rigidity contact of traditional double; The degree of being compressed of spring 2 has absorbed the influence of bent axle brachycephaly machining accuracy to crank throw processing and the long requirement on machining accuracy of one-cylinder diesel machine crankshaft; Realize utilizing the positioning action that connects 4 pairs of crank throws of cover,, obviously improved production efficiency being prone to reach desired dimension precision requirement after the processing on the numerically controlled lathe.
