Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of fixture being specifically designed to cable clip endoporus turnery processing.
The technical solution used in the present invention is such: a kind of fixture for cable clip endoporus turnery processing, comprise clamp body, positioning sleeve and positioning core axle, described clamp body is two-stage Step Shaft, its left side segment outer surface has tapering, on the right of it, three row three row locating holes are offered in large section right side centered by the center of circle, wherein, dog screw and pressing plate is equipped with in the locating hole of first and third interline and the locating hole at the second row two ends, the locating hole of home position is blind hole and is socketed with positioning sleeve in this locating hole, has the positioning core axle inserted from right to left in described positioning sleeve.
As preferably, also comprise a trip bolt, this trip bolt screw in outside clamp body until home position locating hole in and positioning sleeve is fastening.
As preferably, described positioning sleeve outer surface also has a circle groove, trip bolt be pushed against after screwing in outside clamp body in this groove, positioning sleeve is pushed against fixing.
As preferably, the tapering of the segment outer surface of described clamp body is Morse's taper.Segment outer surface has tapering, and it can be inserted taper hole before lathe spindle by the present invention easily in use, does not need very careful aligning can complete this action, and accurate positioning is reliable, time saving and energy saving.
As preferably, there is blind screw hole the left part of described clamp body segment.The present invention and main shaft pull bar with the use of, inner hole of spindle is screwed in clamp body blind screw hole, by the tapering of clamp body segment and the taper hole compact siro spinning technology of main shaft pull bar, thus clamp body is fastened on main shaft pull bar.
As preferably, the locating hole of described clamp body large section of right side home position is interior stepped hole.Interior stepped hole can make the assembling of positioning sleeve convenient, quick.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: can accurately locate eccentric orfice to be processed fast, location efficiency is high; Without acceptance of persons, during rotary work, there is not potential safety hazard in clamp body itself; Cable clip assembly volume to be processed is little, lightweight, and the vibration that the bias of itself causes is less, and crudy is guaranteed; Simple and reasonable, easy to operate, security performance is strong, convenient operation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment 1: as shown in Figure 1, a kind of fixture for cable clip endoporus turnery processing, comprise clamp body 1, positioning sleeve 4 and positioning core axle 5, described clamp body 1 is two-stage Step Shaft, its left side segment outer surface has tapering, on the right of it, three row three row locating holes are offered in large section right side centered by the center of circle, wherein, dog screw 6 and pressing plate 7 is equipped with in the locating hole of first and third interline and the locating hole at the second row two ends, the locating hole of home position is blind hole and is socketed with positioning sleeve 4 in this locating hole, has the positioning core axle 5 inserted from right to left in described positioning sleeve 4.The tapering of the segment outer surface of described clamp body 1 is Morse's taper.
Embodiment 2: as Fig. 1, shown in Fig. 2, a kind of fixture for cable clip endoporus turnery processing, comprise clamp body 1, positioning sleeve 4 and positioning core axle 5, described clamp body 1 is two-stage Step Shaft, its left side segment outer surface has tapering, on the right of it, three row three row locating holes are offered in large section right side centered by the center of circle, wherein, first, dog screw 6 and pressing plate 7 is equipped with in the locating hole of three interlines and the locating hole at the second row two ends, the locating hole of home position is blind hole and is socketed with positioning sleeve 4 in this locating hole, the positioning core axle 5 inserted from right to left is had in described positioning sleeve 4.Also comprise a trip bolt 3, this trip bolt 3 screw in outside clamp body 1 until home position locating hole in and by fastening for positioning sleeve 4.Described positioning sleeve 4 outer surface also has a circle groove, trip bolt 3 is pushed against in this groove after screwing in outside clamp body 1 and pushes against fixing by positioning sleeve 4.
The tapering of the segment outer surface of described clamp body 1 is Morse's taper.
There is blind screw hole the left part of described clamp body 1 segment.
The locating hole of described clamp body 1 large section of right side home position is interior stepped hole.
Below the concrete use of embodiment 2 is elaborated:
1, dismantle lathe three-claw chuck during turning, directly the segment of left for clamp body 1 proper divisor Morse tapering inserted taper hole location before lathe spindle, then by pull bar from strain clamp concrete 1 after main shaft; Can ensure that fixture is consistent with the centre of gyration of main shaft like this, registration is reliable.
In order to alleviate the weight of clamp body 1 and shorten the length of trip bolt 3, clamp body 1 neck can also be offered a circle groove, specifically as shown in Figure 2;
2, according to the size of operation hole milling on CA cable assembly folder 2, corresponding positioning sleeve 4 is adopted to be inserted in clamp body 1 endoporus left side, then, with trip bolt 3 from clamp body 1 neck groove penetrate until locating hole in and fastening by the groove on positioning sleeve 4 outer surface;
3, by cable clip assembly 2 near clamp body 1 right side;
4, the positioning core axle 5 of correspondence is passed hole to be processed, clamp body 1 endoporus of cable clip assembly 2, be inserted in the hole in positioning sleeve 4 always and cable clip assembly 2 is accurately located;
5, utilize another two holes to be processed on cable clip assembly 2, overlap top board 7 with dog screw 6 and dog screw 6 screwed in further compression cable clip assembly 2 in corresponding positioning spiro pit.On clamp body 1, other locating hole just wouldn't arrange dog screw 6 and packing ring 7 when processing this hole;
6, after compressing cable clip assembly 2, positioning core axle 5 is extracted out;
7, the shoulder to be processed on processing cable clip assembly 2 and circular hole.
As shown in Figure 1, cable clip assembly 2 there are three holes to be processed.
When the hole to be processed of turning electric cable clip assembly 2 top right, utilize in the hole to be processed of top left, the hole to be processed of bottom and dog screw 6 and pressing plate 7 clamp; When wanting the hole to be processed of turning electric cable clip assembly 2 top left, screw out trip bolt 3 and dog screw 6, cable clip assembly 2 is moved right, then uses the hole to be processed of positioning core axle 5 positioning cable clip assembly 2 top left, then repeat the step of 3-7 above.
To the similar aforesaid operations of process in the left side, cable clip assembly 2 bottom and the right hole to be processed.
Mentality of designing of the present invention: just with which location, hole to be processed during which hole of turning, clamp with all the other holes.Through practice, can shorten 94% to the time of cable clip assembly 2 centering location than originally, working (machining) efficiency improves more than three times.The cable clip assembly 2 in three holes or four holes is processed and all can adopt same frock.During the hole of turning different-diameter, only need to change positioning sleeve 4 and positioning core axle with matching 5, hole machined in the cable clip that just can complete multiple series.
