Description
Technical field
The utility model is related to a kind of RV speed reducers planet carrier clamp for machining.
Background technology
Existing RV speed reducers planet carrier processing is output seat and pivot flange after semifinishing outer diameter and precision-machined surface
With 50:1 taper pin positioning, hexagon socket head cap screw link together, and form planet carrier assembly, and output face is developed workbench and compressed,
After processing centre bore, then with 1000:1 mandrel is inserted into finishing planet carrier outer diameter in centre bore, thus needs to row
Carrier secondary clamping not only influences machining accuracy, but also processing efficiency is low, in addition due to being close between centre bore and mandrel
Cooperation, therefore mandrel is seperated with planet carrier more difficult.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of RV speed reducers planet carrier clamp for machining, including chassis, clamping bar and positioning pin, chassis and planet carrier pivot flange
It is fixedly connected, more positioning pins are flexibly connected with chassis, and each positioning pin is inserted in planet carrier pin hole, and clamping bar is connected to chassis
One end, clamping bar are used to be sequentially connected with machine tool hydraulic collet.
A plurality of deep gouge corresponding with each camshaft hole of planet carrier is equipped on chassis.
A grooving is equipped on each positioning pin.
Further include pushing mechanism, the pushing mechanism includes the jacking block being arranged in chassis, is fixedly mounted in chassis
The hydraulic oil pipe that cylinder sleeve and one end are connected to cylinder sleeve, is equipped with piston in cylinder sleeve, and piston is connect by connecting rod with jacking block
Positioning pin is tail leader taper pin, and tail leader taper pin screw rod is connect after passing through chassis with nut.
Clamping bar is equipped with a cavity by attachment screw and chassis detachable connection in clamping bar and chassis, cylinder sleeve passes through company
Screw is connect to be removably mounted in cavity.
Chassis is fixedly connected by multiple attachment screws with planet carrier pivot flange.
The utility model has the beneficial effects that：By being accurately positioned to planet carrier and chassis first with positioning pin, together
When chassis is fixedly connected with planet carrier using attachment screw, then clamping bar is connected on machine tool hydraulic collet, processes planet
After frame centre bore, lathe can realize that only once clamping can be completed pair to be directly processed to planet carrier outer diameter after tool changing
The finishing of planet carrier centre bore and outer diameter not only increases machining accuracy, and reduces clamping times, and processing efficiency obtains
It is promoted.

Specific implementation mode
As shown in Fig. 1 to 3, a kind of 6 clamp for machining of RV speed reducers planet carrier, including chassis 1, clamping bar 2, positioning pin 3 and company
Screw 4 is connect, chassis 1 is connect by more attachment screws 4 with 6 pivot flange 62 of planet carrier, more positioning pins 3 and 1 activity of chassis
Connection, positioning pin 3 can be tail leader taper pin, pass through screw rod 33 and nut 32 and 1 detachable connection of chassis, each positioning pin 3
It being inserted in 6 pin hole of planet carrier, for positioning planet carrier 6 and chassis 1, clamping bar 2 is fixedly connected positioning pin 3 with chassis 1,
Clamping bar 2 is used to be sequentially connected with machine tool hydraulic collet.
The application method of the utility model is：It unclamps the nut 32 on positioning pin 3 slightly first, allows positioning pin 3 can be
It is shaken in 1 through-hole of chassis, then planet carrier 6 is installed on chassis 1, allow each positioning pin 3 to be inserted in 1 pin hole of chassis, by planet
The all parts reliable location of frame is packed into more attachment screws 4 and is fixedly connected with planet carrier 6 with chassis 1, and opposite direction is staggeredly tightened,
Finally clamping bar 2 is installed in machine tool hydraulic collet, realizes that lathe is to 6 centre bore 63 of planet carrier to the Set and Positioning of planet carrier
After completion of processing, it can not have to remove planet carrier 6, it will be able to be processed 6 outer diameter of planet carrier, improve machining accuracy and add
Work efficiency rate.
A plurality of deep gouge corresponding with 6 each camshaft hole 64 of planet carrier 11 is equipped on chassis 1.It is needing to use reamer pair
When 6 each camshaft hole 64 of planet carrier is finished, reamer head can be extend into deep gouge 11, with thorough to camshaft hole 64
Processing.
A grooving 31 is equipped on each positioning pin 3.When positioning pin 3 to be inserted into 1 pin hole of chassis, in pin hole
Air can be discharged from grooving 31, with prevent positioning pin 3 cause to be inserted into due to by vapour lock it is difficult.
Further include pushing mechanism 5, the pushing mechanism 5 includes the jacking block 52 being arranged in chassis 1, is fixedly mounted on chassis
The hydraulic oil pipe 55 that cylinder sleeve 51 and one end in 1 are connected to cylinder sleeve 51, is equipped with piston 53 in cylinder sleeve 51, and piston 53 passes through connecting rod
54 connect with jacking block 52, and hydraulic oil pipe 55 can be connected to hydraulic circuit in hydraulic chuck.Since positioning pin 3 and planet carrier 6 are sold
It is using being fitted close between hole, therefore planet carrier 6 compares and is difficult to extract from positioning pin 3, at this point it is possible to by hydraulic oil pipe 55
Hydraulic oil is injected into cylinder sleeve 51, and piston 53 pushes jacking block 52 to release planet carrier 6 from chassis 1, to be carried out to planet carrier 6
Dismounting, further improves processing efficiency.
For clamping bar 2 by attachment screw and 1 detachable connection of chassis, clamping bar 2 and chassis 1 are interior equipped with a cavity, cylinder sleeve 51
