Description
Technical field
The utility model relates to a kind of lathe, particularly relates to a kind of fixture of machining center long drill bit.
Background technology
Along with the develop rapidly of China's automobile, mould, Aeronautics and Astronautics, electronics, plastics, alloy industry, traditional hand miller can not meet the demand of processing manufacturing industry.Although China's CNC milling machine and machining center import volume are all in cumulative year after year, but still can not meet the demand of domestic processing industry.Therefore, domestic numerical control milling machine, machining center that accelerate development cost performance is higher are the task of top priority and the prior development direction of domestic each specialised manufacturers.
The producer of domestic and international production vertical machining centre is more, has the DECKEL company, Japanese Mazak Co., Ltd. etc. of the MIKRON company of Switzerland, Germany abroad; There are Beijing first Machine Tools Plant, Jinan No.1 Machine Tool Plant in domestic well-known producer, Dalian, Shenyang, the Long March, Guilin machine tool plant etc.But in the processing of some peculiar parts, above-mentioned preferential shop mostly produces universal machine tools, the demand of special parts machining cannot be met, such as, in deep hole drilling, because drill bit is longer, often work in-process easily rocks, and affects crudy, causes the situation that the hole form and position tolerance after processing is not up to standard.
Utility model content
The purpose of this utility model is to solve technical problem involved in background technology, providing a kind of fixture of machining center long drill bit.
The technical solution of the utility model is: a kind of fixture of machining center long drill bit, comprise the hoop for being connected with toolframe, hoop is provided with the ring cavity for holding toolframe, described ring cavity is provided with an opening on hoop, the both sides of described opening are respectively provided with a pressure side head, described pressure side head is used for holding toolframe tightly through bolt, the periphery static connection of described hoop has one end of the support arm along its axis direction development length, the other end static connection of described support arm has the swing arm along hoop radial direction development length, one end of described swing arm is provided with roller ball, described swing arm is provided with one end of roller ball for propping up drill bit.
Preferred as one, on described hoop, radially direction is provided with convex falcon, described convex falcon is fastened in the groove on support arm, and described convex falcon and support arm all offer through hole, and one end of described through hole is through bolt and with nut the fastening convex falcon on connecting support arm and hoop of the other end.
Preferred as one, described swing arm offers multiple chute, and described support arm is provided with projection, and described projection matches with chute, the setting parallel to each other of described multiple chute, when described projection matches from different chutes for regulating on swing arm roller ball to the distance of hoop axis.
In sum, the utility model has following advantage:
Fixture of the present utility model makes long drill bit add man-hour, and cutter not easily rocks, and improves crudy, reduces to rock simultaneously, reduces the loss of drill bit, and can adapt to the drill bit processing operation of different size.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
As shown in Figure 1-2, a kind of fixture of machining center long drill bit, it is characterized in that: comprise the hoop 1 for being connected with toolframe, hoop 1 is provided with the ring cavity 11 for holding toolframe, described ring cavity 11 is provided with an opening 12 on hoop 1, the both sides of described opening 12 are respectively provided with a pressure side 13, described pressure side 13 is used for holding toolframe tightly through bolt, the periphery static connection of described hoop 1 has one end of the support arm 2 along its axis direction development length, the other end static connection of described support arm 2 has the swing arm 3 along hoop 1 radial direction development length, one end of described swing arm 3 is provided with roller ball 4, described swing arm 3 is provided with one end of roller ball 4 for propping up drill bit.On described hoop 1, radially direction is provided with convex falcon 14, described convex falcon 14 is fastened in the groove 21 on support arm 2, described convex falcon 14 and support arm 2 all offer through hole, and one end of described through hole is also fastening for the convex falcon 14 on connecting support arm 2 and hoop 1 at the other end with nut through bolt.Described swing arm 3 offers multiple chute 31, described support arm 2 is provided with protruding 22, described protruding 22 match with chute 31, the setting parallel to each other of described multiple chutes 31, when described protruding 22 match from different chutes 31 for regulating roller ball 4 on swing arm 3 to arrive the distance of hoop 1 axis.
More than illustrate it is only to explanation of the present utility model, those of ordinary skill in the art's can completely is made to implement this programme, but be not to restriction of the present utility model, those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this description, and these are all not creative amendments.As long as but be all subject to the protection of Patent Law in right of the present utility model.
