To achieve the above object, the utility model provides following technical solution: a kind of four-way elbow clamp, including four-way
Elbow, including the fixed station being vertically arranged, the fixed station is connected with rack, and the rack includes curved for placing four-way
The placement plate of head and placement plate two sides are arranged in and connect with fixed station two side guard plates are set between described two side guard plates
It is equipped with the bracket being located above four-way elbow, there are two support respectively with two elbows of four-way elbow top for setting on the bracket
The screw rod fixation kit connect, setting is respectively arranged with ball on described two support bases there are two support base on the fixed station
Bearing, two ball bearings are connected with rotating bar jointly, and the shelves worn for rotating bar, institute are provided on a side guard plate
The fastening bolt for being provided in shelves and capable of fastening rotating bar is stated, is also set up on the fixed station there are two sleeve, described two
The piston rod abutted with two elbow sides of four-way elbow is provided in a sleeve, the rotating bar is fed through two sleeves,
The eccentric wheel abutted with piston rod is fixedly installed in the rotating bar.
Preferably, one end of the rotating bar is provided with handwheel.
Preferably, the screw rod fixation kit includes the screw rod for being fed through bracket, and the lower end of the screw rod is connected with V
The pushing block of shape slot.
Preferably, the guide rod for being fed through bracket is provided on the pushing block.
The utility model has the following advantages compared with the prior art, and passes through two screw rod fixation kit energy on bracket
It is enough to limit two elbows of four-way elbow in vertical direction, rotating bar is then adjusted, rotating bar band movable eccentric wheel pushes away
Move two piston rods, two piston rods can simultaneously abut the side of two elbows, the benefit being arranged in this way be even if
Enable to two elbows stress simultaneously the error of some elbow will not be caused to increase even if there are errors when its casting.
When rotating bar is adjusted to suitable position, rotating bar can be fixed by fastening bolt, so that piston rod is stablized
Thrust, by setting ball bearing can when adjusting rotating bar it is more laborsaving.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of four-way elbow clamp, including four-way elbow 1, it is described solid including the fixed station 2 being vertically arranged
Determine platform 2 and be connected with rack 3, the rack 3 includes placement plate for placing four-way elbow 1 and is arranged in placement plate two
Side and two side guard plates 4 being connect with fixed station 2, the branch being provided between described two side guard plates 4 above four-way elbow 1
Frame 5, setting is described there are two respectively with the screw rod fixation kit that abuts at the top of two elbows of four-way elbow 1 on the bracket 5
Setting is respectively arranged with ball bearing 7, two balls on described two support bases 6 there are two support base 6 on fixed station 2
Bearing 7 is connected with rotating bar 8 jointly, is provided with the shelves 9 worn for rotating bar 8 on a side guard plate 4, in the shelves 9
It is provided with the fastening bolt 10 that can fasten rotating bar 8, is also set up on the fixed station 2 there are two sleeve 11, described two sets
It is provided with the piston rod 12 abutted with two elbow sides of four-way elbow 1 in cylinder 11, the rotating bar 8 is fed through two sleeves
11, the eccentric wheel 13 abutted with piston rod 12 is fixedly installed in the rotating bar 8.
A kind of 1 fixture of four-way elbow of this programme, can be curved by four-way by two screw rod fixation kits on bracket 5
First 1 two elbows are limited in vertical direction, then rotate rotating bar 8, and rotating bar 8 pushes two with movable eccentric wheel 13
Piston rod 12, two piston rods 12 can simultaneously abut the side of two elbows, and the benefit being arranged in this way is i.e. enabled
Enough so that two elbows while stress will not cause the error of some elbow to increase even if there are errors when its casting.When
