The utility model discloses a tool fixture for drilling an anchor plate, and relates to the technical field of machining. The tool fixture comprises a fixture base and a chuck, wherein a support shaft and an indexing sleeve sleeved outside the support shaft are arranged between the chuck and the fixture base; the support shaft is fixedly connected to the middle part of the fixture base; the indexing sleeve is connected with the chuck through a spigot; bearings are arranged between the indexing sleeve and the support shaft; an axial locking nut is arranged on the support shaft; a bracket is fixedly arranged outside the fixture base; a positioning device for locking the indexing sleeve is connected to the bracket. Compared with the prior art, the tool fixture is not required to be repeatedly disassembled, and is low in labor intensity, high in working efficiency, easy to operate and high in machining accuracy.
Description
Technical field
The utility model relates to Machining Technology field, especially a kind of auxiliary mould of holing on anchor slab.
Background technology
Existing a kind of frock of holing on anchor slab is to get the anchor slab mould of structure ready, the operation of this frock is more complicated all, also needs in use repeatedly to dismantle anchor slab mould need to put die location, its complex operation by boring, inefficiency, labour intensity is large.
Utility model content
The purpose of this utility model is to provide a kind of anchor slab drilling tool fixture, and this fixture can solve the large problem of complex operation, inefficiency, labour intensity that existing anchor slab drilling tool exists.
In order to address the above problem, the technical solution adopted in the utility model is: this anchor slab drilling tool fixture comprises clamp base and chuck, between described chuck and described clamp base, be provided with back shaft and be sleeved on the calibration cover outside described back shaft, described back shaft is fixedly connected on the middle part of described clamp base, described calibration cover is connected by seam with described chuck, between described calibration cover and described back shaft, bearing is installed, axial locking nut is installed on described back shaft; The outside of described clamp base is installed with support, is connected with for locking the positioner of described calibration cover on described support.
In above-mentioned anchor slab drilling tool clamp technology scheme, technical scheme can also be more specifically: described back shaft is hollow shaft sleeve, between described calibration cover and described back shaft, dust cap is housed.
Further, described positioner comprises locking nut radially and with the alignment pin of handle, described radially locking nut is fixed on described support, on described alignment pin, be fixed with the orienting cover being threaded with described radially locking nut, described alignment pin be axially perpendicular to described calibration cover axially.
Further, described bearing comprises two cover angular contact ball bearings, between the outer ring of described angular contact ball bearing, is provided with spacer ring.
Further, described clamp base and described back shaft are by being welded and fixed.
Further, described chuck is scroll chuck.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: processing work only needs clamped one time rapid processing to go out a plurality of borings that distribute on circumference, and frock clamp does not need repeatedly to dismantle yet, its labour intensity is low, operating efficiency is high, simple to operate, machining accuracy is high; Dust cap is set, can effectively avoids break flour to splash in bearing, affect the service behaviour of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of this anchor slab drilling tool fixture.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Anchor slab drillman clamping shown in Fig. 1 mainly comprises clamp base 1, back shaft 2, calibration cover 3, bearing, dust cap 7, chuck and positioner, one end face of clamp base 1 is provided with and coordinates the locating piece of installing with drilling machine, at the middle part of clamp base 1, be welded with from other end outward extending back shaft 2, this back shaft 2 is a hollow shaft sleeve, the outer calibration cover 3 that is set with of back shaft 2, the outer wall of calibration cover 3 is provided with groove and the scale value of angle index; Between calibration cover 3 and back shaft 2, bearing is installed, the inwall of calibration cover 3 and the outer wall of back shaft 2 are respectively arranged with for installing and limit the limited step of bearing, bearing comprises two cover angular contact ball bearings 4, between the outer ring of two cover angular contact ball bearings 4, be provided with spacer ring 5, the axial locking nut 6 that locking bearing is also installed on back shaft 2, axial locking nut 6 is pressed in the inner ring end face of angular contact ball bearing 4; One end at calibration cover 3 is connected with the chuck for clamping work pieces by seam, and the chuck in the present embodiment is scroll chuck 8, can be with four paws or five dog chucks etc. in other embodiment, and calibration cover 3 and scroll chuck 8 rotate around back shaft 2 by bearing; In order to keep processing work motionless in the position of setting in boring procedure, at calibration, overlap 3 arranged outside positioners, positioner comprises locking nut radially 11 and with the alignment pin 10 of handle 13, radially locking nut 11 is fixed on a support 9, this support 9 is fixedly connected on the outside of clamp base 1, on alignment pin 10, be fixed with and orienting cover 12 that radially locking nut 11 is threaded, alignment pin 10 be axially perpendicular to calibration cover 3 axially, alignment pin 10 is provided with the position baseline matching with graduation mark on calibration cover 3.It is worth mentioning that, for fear of the break flour producing in process from calibration, the gap of cover 3 and back shaft 2 terminations enters in bearing, between calibration cover 3 and back shaft 2, dust cap 7 is housed, dust cap 7 is placed between scroll chuck 8 and back shaft 2, and insert in the axis hole of back shaft 2 one end of dust cap 7.
Before work, this anchor slab drilling tool fixture is fixed on drilling machine, again semi-finished product anchor slab is fixed on scroll chuck 8, rotating calibration cover 3 makes the graduation mark of start angle of calibration cover 3 corresponding with the position baseline of alignment pin 10, turning handle 13, alignment pin 10 is moved towards calibration cover 3, until calibration cover 3 is positioned, pin 10 is locked completely, just can start boring work.While having bored a hole, turning handle 13 in the opposite direction, alignment pin 10 is moved towards the direction away from calibration cover 3, to unclamp the locking state of calibration cover 3, rotate calibration cover 3, the anchor slab being clamped by scroll chuck 8 rotates thereupon, when the angle index line on calibration cover 3 corresponding to next one boring to be processed and the position baseline on alignment pin 10 align, the calibration that is locked cover 3, starts to process next hole; According to aforementioned operation, process all anchor slab borings on the same circumference that is distributed in anchor slab, it is simple to operate, and machining accuracy is high.
