Embodiment
The brake shoe iron boring grab is filled by clamp body 1, connecting plate 2, rotary shaft 3, index dial 4, bushing plate 5, positioning
Put, alignment pin A6, alignment pin B7 and locking device are constituted：One end of clamp body 1 is fixed with connecting plate 2, and the boring grab passes through
Connecting plate 2 is arranged on the workbench of lathe.
Rotary shaft 3 is equipped with by bearing activity in clamp body 1, one end of rotary shaft 3 extends to the outer end of clamp body 1, extended
Index dial 4 is installed on to the termination of clamp body outer end；Multiple bayonet sockets 14 are evenly equipped with the periphery of index dial 4, index dial 4 can
Rotary shaft 3 is driven to rotate together.
When workpiece 22 is installed on index dial 4, and bayonet socket 14 is connected with the insertion of latch 16, the underlying workpiece 22 of drill bushing 12 is oriented to
Periphery position be need process rivet hole position.Therefore the latch 16 of the boring grab is inserted into card in the course of work
Rivet hole machined is directly carried out after mouth 14, indexing positioning is carried out without artificial, so as to improve machining accuracy.
The top of index dial 4 is provided with guide groove 10, guide groove 10 by adjusting screw mandrel 11 equipped with bushing plate 5；Filled on bushing plate 5
There is guiding drill bushing 12, in the case where being oriented to the guiding of drill bushing 12, the drill bit of lathe completes brake shoes after may pass through guiding drill bushing 12
The processing of rivet hole.People can be by way of rotating regulation screw mandrel 11 along the upper of the regulation bushing plate 5 of guide groove 10 in the course of work
Lower position, the need for the brake shoe iron foot processing of full different model.
The lower section of index dial 4 is provided with positioner；Positioner is by depression bar 15, latch 16, push spring 17, adjusting screw
18 and mounting seat 19 constitute, mounting seat 19 is packed on clamp body 1；In mounting seat 19 by assemble through hole 20 be slidably fitted with it is slotting
Pin 16, the adjusting screw 18 that the lower section of latch 16 is connected through a screw thread is provided with push spring 17；Spring 17 is pushed to support with latch 16
Touch connection；Latch 16 can be plugged into insert with index dial 4 in bayonet socket 14 in the presence of the push elastic force of spring 17 is pushed and be connected,
And then index dial 4 can be fixed.The side of latch 16 is hinged with depression bar 15, and depression bar 15 is by rotating pin 21 and latch
16 are connected with each other.
Alignment pin A6, alignment pin B7 and locking device are fixed with the end face of index dial 4.Locking device is by push rod 8, locking
Bolt 9, back-moving spring 13 and pressing plate 23 are constituted, and pressing plate 23 is movably installed with by clamping screw 9 on the end face of index dial 4, pressure
Plate 23 can be rotated around clamping screw 9；The side of clamping screw 9 is fixed with push rod 8；Push rod 8 is contradicted with pressing plate 23 and is connected；Pressing plate 23 with
Back-moving spring 13 is provided between index dial 4.The purpose for setting push rod 8 is：When tightening the nut of clamping screw 9, on top
Under the branch support power of bar 8 and the effect of the thrust of the nut of clamping screw 9, one end of pressing plate 23 can give in a balanced way pressure by work
Part 22 is compressed.
In the brake shoe iron boring grab course of work, it is necessary first to which the two ends stomidium of workpiece 22 is inserted into alignment pin
In A6 and alignment pin B7, the one end of pressing plate 23 is turned to the top of workpiece 22, the nut of clamping screw 9 is then tightened, now presses
Workpiece 22 is fixedly clamped on index dial 4 by plate 23 under the cooperation of push rod 8.
After the clamping of workpiece 22 is finished, moulded rod 15 can be descended, depression bar 15 can drive latch 16 to be separated with bayonet socket 14, then rotated
Index dial 4 unclamps depression bar 15 when 16 pairs of first bayonet socket 14 and latch are corresponding.Now push spring 17 in the presence of latch 16
It can be inserted into first bayonet socket 14 and fix index dial 4.Subsequent start-up drilling machine, the drill bit of drilling machine can be oriented to drawing for drill bushing 12
Lead the processing of the lower completion rivet hole of workpiece 22.After completion of processing, lower moulded rod 15 rotates index dial 4, and then unclamping depression bar 15 makes
Latch 16 is inserted into next bayonet socket 14, and subsequent drilling machine can complete the processing of next rivet hole.Such iterative cycles, when all
After rivet hole completion of processing；The workpiece 22 that clamping screw 9 then removes completion of processing is unclamped, loads new workpiece 22
Into next circulation.
When the boring grab processes the brake shoes of other models, it is only necessary to which replacing with corresponding index dial 4 can expire
Foot processing needs；Solve existing fixture process other models brake shoes need to fixture carry out integral replacing when have
Labor intensity is big and the problem of inefficiency.And the boring grab is that workpiece 22 is entered by the bayonet socket 14 on index dial 4
The accuracy of row indexing is high, it is to avoid when existing fixture is using artificial indexing, and the precision having is low to easily cause brake shoes
The problem of rivet hole site is deviateed, the need for meeting enterprise's production and application.
