Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
Welding stand of thin-wall drill comprise support 1 and be arranged on support 1 for locate thin wall drill base body 5 positioner, for the clamping and positioning device of clamping position thin-walled drill cutter head 6 and for limiting thin wall drill base body 5 degree of rotation and ensureing the indexing means etc. that the number of degrees of each degree of rotation are equal.
Embodiment one
As depicted in figs. 1 and 2, positioner comprises the keeper 1 be fixed on support 1 and the keeper 34 being positioned at the keeper two immediately below keeper 1 and being positioned at outside keeper 1.Keeper two is connected on support 1 by slide rail; Keeper 34 is fixedly connected with on support 1 by support bar 2.Thin wall drill base body 5 vertically arranges its head and can be located by keeper 1, keeper two, keeper 34 upward.
This indexing means comprises base 7 and index lever 8.Specifically, index lever 8 is shaft-like and its one end is hinged on base 7, and the other end of index lever 8 is free end and this end can lean with an end face of the thin-walled drill cutter head 6 be positioned on support 1.
Support bar 2 is horizontally disposed with and is positioned at the side of keeper 1, in round bar shape bottom base 7, the outer wall of bottom is provided with screw thread.Support bar 2 has connecting hole, is connected with locking nut 9 through connecting hole bottom base 7, turns locking nut 9 and base 7 can be made to be fixed on support bar 2.And when base 7 is not locked base 7 can along it bottom axis rotation, index lever 8 is swung, and then changes the circumferential position of index lever 8 free end.
This indexing means is adopted to limit thin wall drill base body 5 degree of rotation and the equal use step of the number of degrees of each degree of rotation is as follows:
First, marking line: the radian calculating decile according to cutter head 6 number; On matrix 5, any place marks the mark line of the first cutter head 6 present position, adopts measurer to assist the mark line marking an adjacent cutter head of the first cutter head 66 (being called the second cutter head 6) present position on matrix 5 according to the above-mentioned radian calculated;
Then, weld the first cutter head 6: to be positioned by matrix 5 on support 1 and to weld a cutter head 6 at the mark line place of the first cutter head 6 present position of matrix 5, rotating matrix 5 makes the mark line of the second cutter head 6 present position relative with cutter head 6, and above-mentioned cutter head 6 and the benchmark of mark line all should keep identical;
Then, regulate index lever 8 position: ensure that base 7 is not locked, rotating base 7 makes an end face of the first cutter head 6 of the free end of index lever 8 and thin-walled drill lean, general select matrix 5 rotation direction preferentially and the end face that leans of index lever 8; Index lever 8 relies on the end face of matrix 5 under gravity simultaneously, now, turns locking nut 9 and base 7 can be made to be fixed on support bar 2.Cause index lever 8 flexural deformation in order to avoid firmly excessive when cutter head 6 and index lever 8 lean, and cause matrix 5 rotational angle to produce larger error, thus, the metal materials such as index lever 8 aluminium alloy or iron and steel are made and also select suitable diameter.Because the spacing of two adjacent of some thin-walled drills may be also less than the diameter of index lever 8, so be provided with slot to make way 84 in the free end end of index lever 8, this slot to make way 84 is set and namely can ensures that index lever 8 can lean with the end face of cutter head 6, the flexural strength of index lever 8 can be ensured again.
Finally, limit matrix 5 successively rotate and weld cutter head 6: weld a cutter head 6 at the mark line place of the second cutter head 6 present position of matrix 5; Lifting index lever 8 with hand makes its free end depart from the first cutter head 6, rotates thin wall drill base body 5 and the end face of the free end of index lever 8 and the second cutter head 6 is leant; Now lived immediately below cutter head 6 to be the 3rd cutter head 6 present position by clamping and positioning device clamping position, weld a cutter head 6 at the 3rd cutter head 6 present position place of matrix 5; Circulation is lifted index lever 8 and is leant and weld cutter head 6 with cutter head 6 end face next time, until welded whole cutter head 6 successively.
As can be seen here, this indexing means has that structure is simple, easy to use, restriction thin wall drill base body 5 degree of rotation and ensure the advantage that the number of degrees error of each degree of rotation is little, thus the effective guarantee cutter head 6 be fixed on matrix 5 is uniformly distributed, and improves the quality of thin-walled drill.
Due to, matrix 5 diameter of the thin-walled drill of different model is different, and the distance namely between cutter head 6 to base 7 is different, in order to ensure that the free end of index lever 8 all can lean with the end face of cutter head 6, improve the scope of application of this indexing means, so this index lever 8 comprises mobile jib 81 and expansion link 82.One end and the base 7 of mobile jib 81 are hinged, and the other end of mobile jib 81 axially has telescopic hole 811.One end of expansion link 82 is located in telescopic hole 811, and the other end of expansion link 82 is free end, and mobile jib 81 is provided with clamping screw 83, and the head of clamping screw 83 penetrates telescopic hole 811, turns clamping screw 83 and expansion link 82 can be made to be fixed on mobile jib 81.And expansion link 82 can move axially along telescopic hole 811 when expansion link 82 is not locked, and then change the axial location of index lever 8 free end.
Embodiment two
The present embodiment with the structure of embodiment one and principle substantially identical, different place is: conveniently rotating base 7 and improve the accuracy of rotational angle, is connected by index dial 10 between base 7 and support bar 2 thus.The bottom of base 7 is fixed on the center of index dial 10, and index dial 10 is fixed on support bar 2 by bolt and nut.Index dial 10 be can make that base 7 rotates, a kind of mechanism of calibration and location.The structure of index dial 10 is primarily of retained part, calibration localization part, running part composition.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ support 1 herein; Support bar 2; Keeper 1; Keeper 34; Matrix 5; Cutter head 6; Base 7; Index lever 8; Mobile jib 81; Telescopic hole 811; Expansion link 82; Clamping screw 83; Slot to make way 84; Locking nut 9; Term such as index dial 10 grade, but do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
