Abstract
A kind of two screw tool section clamping structure.Its composition comprises: cutterhead body (1), pre-loading screw (2), lock-screw (3), outer shroud (4) briquetting (5).Cutterhead body has the cutter groove placing blade, on outer shroud, the position of corresponding each cutter groove has the screwed hole of two rigging screws.Described briquetting is connected with lock-screw by draw-in groove, and on described briquetting, the opposite of described draw-in groove is pressed on the tool section in insertion cutter groove, and the described pre-loading screw bottom of thread is equipped with spring, and the spring other end is squeezed on briquetting.The utility model is used for the clamping of pointed tooth formula cutterhead tool section.
Description
Technical field
The utility model relates to a kind of clamping structure of field of machining tool section, is specifically related to a kind of clamping structure of pointed tooth formula cutterhead tool section.
Background technology
Gear drive is most widely used a kind of type of belt drive in machine driving, current spiral gear with duplex tapered teeth is at noise, intensity, there is its unique advantage stationarity aspect, so in car industry, aviation, apply more and more extensive in the modern mechanicals such as space flight, and be the crucial drive disk assembly do not replaced, processing spiral gear with duplex tapered teeth adopts pointed tooth formula cutterhead, this type of cutterhead is high especially to toolsetting coherence request, the tool section clamping clamping structure adopting single screw and fixture block of this type of cutterhead in the past more, when locking after toolsetting completes, tool section easily movement causes toolsetting failure, cause the toolsetting time long.The utility model overcomes this shortcoming just, can not the effect of movement in locking process to reach tool section, makes toolsetting easier, saves the toolsetting time.
Summary of the invention
The purpose of this utility model is to provide one and is applicable to pointed tooth formula cutterhead, prevents the clamping structure of tool section movement when tool section is locked, and this structure is realized by two bolt structure.
The object of above-mentioned utility model is achieved through the following technical solutions:
A kind of two screw tool section clamping structure, be made up of cutterhead body (1), pre-loading screw (2), lock-screw (3), outer shroud (4) briquetting (5), described cutterhead body has the cutter groove placing tool section, the position of the corresponding each cutter groove of described outer shroud has the screwed hole of two rigging screws, described briquetting is connected with lock-screw by draw-in groove, side relative with described draw-in groove on described briquetting is pressed on the tool section that inserts in cutter groove, the described pre-loading screw bottom of thread is equipped with spring, and pretightning force is applied on tool section by spring and briquetting by pre-loading screw.When toolsetting, briquetting is only subject to the elastic force of spring on pre-loading screw, and tool section is easy to adjust, tightens lock-screw after adjustment, owing to being subject to the power of pre-loading screw, so tool section can not be moved during locking, improves toolsetting efficiency.The utility model is used for the clamping of pointed tooth formula cutterhead tool section.
The utility model has following effect: in the pointed tooth cutterhead toolsetting process of processing spiral gear with duplex tapered teeth, toolsetting required precision is very high, pointed tooth cutterhead tool section clamping structure adopted the single screw clamping structure only having a lock-screw in the past, after having adjusted cutter, carry out tool section when lock-screw is locked often be moved, cause toolsetting unsuccessfully to need to readjust.The utility model overcomes this shortcoming just, before lock-screw locking, pre-loading screw first gives briquetting pretightning force by the spring of bottom, just avoids the movement of tool section like this when lock-screw is locked, improve the success rate of toolsetting, substantially increase the efficiency of toolsetting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is front view and the left view of this patent briquetting (5)
Fig. 3 is this patent lock-screw (3)
Fig. 4 is this patent pre-loading screw (2)
Detailed description of the invention
Describe embodiment in detail in conjunction with above accompanying drawing, cutterhead body (1) has the cutter groove placing tool section, the position of the upper corresponding each cutter groove of outer shroud (4) has the screwed hole of two rigging screws.First lock-screw (3) is screwed in top screwed hole, briquetting (5) is inserted in cutter groove, by draw-in groove, briquetting is connected with lock-screw, then screw in pre-loading screw (2), continue to screw in pre-loading screw after tool section inserts cutter groove and make briquetting be pressed onto on tool section, carry out toolsetting afterwards, after toolsetting, lock-screw is locked, in the process because tool section is subject to the power that pre-loading screw passed to by briquetting, so tool section can not be moved during locking, overcome the shortcoming of single screw locking mechanism.
Claims (1)
1. a two screw tool section clamping structure, be made up of cutterhead body (1), pre-loading screw (2), lock-screw (3), outer shroud (4), briquetting (5), described cutterhead body has the cutter groove placing tool section, the position of the corresponding each cutter groove of described outer shroud has the screwed hole of two rigging screws, described briquetting is connected with lock-screw by draw-in groove, side relative with described draw-in groove on described briquetting is pressed on the tool section that inserts in cutter groove, the described pre-loading screw bottom of thread is equipped with spring, and pretightning force is applied on tool section by spring and briquetting by pre-loading screw.
