Abstract
The utility model relates to a three-hole wound constant handle, specifically to a connecting handle used in mechanical driving device and special tool in machine finishing industries. The prior three-hole positioning connecting handle applied in the mechanical driving device and special tools has lower clipping strength and use inconvenience. The utility model includes a large handle body and a cylindrical connecting handle body, the connecting handle body is fixed at one end of the large handle body, and the connecting handle body is integrated with the large handle body, which is characterized in that three positioning concave surfaces are evenly provided on the outer wall of the connecting handle body, the positioning concave surfaces are composed of blind holes and grooves, the grooves are distributed along the axial direction of the connecting handle body, one end of the groove is connected to the blind hole, and the other end of the groove is even to the end-face of the connecting handle. The utility model has reasonable physical design, stable performance, convenient fabrication, long service life, and big clipping strength during use.
Description
Technical field
The utility model relates to a kind of three holes and creates permanent handle, relates in particular to the handle that connects in a kind of mechanical driving device that is used for mechanical processing industry and the dedicated tool, belongs to a kind of five metals machining tool.
Background technology
It is more to be applied in the special-purpose kind that connects handle in three holes location in mechanical driving device and the dedicated tool at present, in use the intensity of clamping is lower but these connect handle, as open day was on 08 13rd, 2008, the patent No. is in the Chinese patent of ZL200720183662.2, a kind of extraordinary three hole handles are disclosed, this passage that connects in the handle adopts the flat mode in plane, and this just causes the cylindrical location area of shank less, thereby greatly reduces product clamping intensity in use.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, stable performance, and permanent handle is created in three holes that clamping intensity is big during use.
The technical scheme in the invention for solving the above technical problem is: this three hole is created permanent handle and is comprised big handle body and the columned handle body that connects, describedly connect the end that the handle body is fixed on big handle body, this connects the handle body and big handle body is connected as a single entity, its characteristics are: be provided with three place's alignment concavity uniformly on the described outer wall that connects the handle body, this alignment concavity is made up of blind hole and groove, described groove is along the axial distribution that connects the handle body, one end of this groove is connected with blind hole, and the other end of described groove flushes with the end face that connects the handle body.
Blind hole described in the utility model is made up of a face of cylinder and a plane.
Groove described in the utility model is an arc groove.
Blind hole described in the utility model is made up of a taper seat and a plane.
The utility model compared with prior art, have the following advantages and effect: the utility model increases shank cylindrical location contact area in use by circular groove, make Area of bearing increase greatly, thereby increased the clamping area of the utility model and anchor clamps, strengthen clamping intensity, improved drill bit locating effect in use.It is stressed that blind hole in the utility model adopts the form on the face of cylinder to carry out, make product in the course of the work be subjected to force intensity better, promoted drill bit performance in use.
The utility model is simple in structure, and is easily manufactured, long service life.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment;
Fig. 2 be the utility model embodiment connect the handle body at the halving hole place along connecing sectional structure schematic diagram after handle body radial direction is dissectd.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, three holes in the present embodiment are created permanent handle and are comprised big handle body 1 and connect handle body 2 that it is cylindric wherein to connect being shaped as of handle body 2, connects the end that handle body 2 is fixed on big handle body 1, it is integral structure that permanent handle is created in three holes in the present embodiment, promptly big handle body 1 and connect handle body 2 and be connected as a single entity.Big handle body 1 in the present embodiment is a prior art.
Be provided with three place's alignment concavity uniformly on the cylindric outer wall that connects handle body 2 in the present embodiment, each alignment concavity is formed by a blind hole 3 and a groove 4, its further groove 4 is along connecing axially distributing of handle body 2, groove one end 41 is connected with blind hole 3, the groove other end 42 flushes with the end face 21 that connects handle body 2, that is to say by groove 4 blind hole 3 and the end face 21 that connects handle body 2 are connected.The axial direction that connects handle body 2 in the present embodiment is common practise for a person skilled in the art.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
