The auxiliary fixing device includes the column 18 set on 1 upper surface of rack；A sliding is equipped with above the column 18 Block 19；A sliding cavity 20 is equipped in 19 lower part of sliding shoe；19 lower surface of sliding shoe is equipped with one and passes through with 20 phase of sliding cavity Logical movable span 21；18 bottom end of column is equipped with a slide bar 22, and 22 diameter of slide bar is less than 18 diameter of column；On the slide bar 22 End is penetrated in sliding cavity 20 by movable span 21 and is equipped with the limit plate 23 to match with sliding cavity 20；19 top of sliding shoe Equipped with a handle 24；The sliding shoe 19 side opposite with handwheel 9 is equipped with an extruded tube 25；The extruded tube 25 and handwheel 9 Opposite side nozzle, which extends internally, limit flange 26；19 top of sliding shoe is equipped with a lateral jack 27；The transverse direction Matched gag lever post 28 is equipped in jack 27；9 outer wall of handwheel is equipped with a limiting slot to match with gag lever post 28 29, limiting slot 29 is in a ring；Described 28 one end of gag lever post penetrates in limiting slot 29, and the other end is equipped with one and is stuck in lateral 27 hole of jack The pull ring 30 of mouth；The gag lever post 28 is externally provided with a pulling plate 31 to fit with limit flange 26；The pulling plate 31 and sliding shoe Spring 32 is equipped between 19, spring 32 is sheathed on outside gag lever post 28.

The gag lever post 28 one end opposite with limiting slot 29 is equipped with positive magnetic sheet 33；Being equipped with one in the limiting slot 29 is in The cathode magnetic sheet 34 of annular, cathode magnetic sheet 34 and positive magnetic sheet 33 are attracting.

The 9 upper surface side of handwheel is equipped with a lever 35 in a vertical shape.

The application method of the utility model is as follows:

The center of rocker arm end can be directed at the point of pilot pin 2 by staff, obtain the position of rocker arm preliminary Positioning, is and then adjusted according to lengthwise position of the specification of rocker arm to pressing plate 16, when adjusting the lengthwise position of pressing plate 16, work Handwheel 9 can be directly selected by making personnel, and with the rotation of handwheel 9, longitudinal screw 8 is rotated with, and elevator 6 passes through longitudinal screw hole 7 are connected with longitudinal screw 8, while elevator 6 is limited to fixing pipe 11, and the guide plate 13 of 6 lower end of elevator can only be along a left side The guide groove 12 of right two sides moves up and down, therefore the power that longitudinal screw 8 rotates can then be converted into moving up and down by elevator 6 Power, to play the effect of lifting, when handwheel 9 rotates, elevator 6 moves up and down therewith, when determining a position, only needs to stop Turn handwheel 9, the position of elevator 6 just longitudinal screw 8 with it is automatic stuck under being threadedly engaged of longitudinal screw hole 7, work as a left side After the lengthwise position of the pressing plate 16 of right two sides determines, can by turn knobs 17, make transverse screw 15 rotate and to 2 direction of pilot pin it is mobile, to drive pressing plate 16, pressing plate 16 is made finally to be pressed on rocker arm surface, the pressing plate 16 of the left and right sides It is pressed on rocker arm simultaneously, rocker arm can not only be made to be clamped and fixed, and make rocker arm uniform force, even if by external force, also not The case where will appear inclination.

It, can not only in summary it is found that the utility model simultaneously can compress rocker arm by the clamping device of the left and right sides Clamping force is enough improved, and makes rocker arm uniform force, stability when rocker arm is clamped is improved, to guarantee rocker arm in clamped condition Lower processing quality when being processed, and the longitudinal screw 8 of clamping device can regulate and control the lengthwise position of pressing plate 16, clamping device Transverse screw 15 can regulate and control the lateral position of pressing plate 16, thus enable staff according to the rocker arm of different size adjust It is reduced when rocker arm is processed so that the rocker arm fixture of the utility model be made to can adapt to the rocker arm of different size the position of rocker arm Trouble, saves the processing cost of rocker arm.

When rocker arm is clamped, rocker arm is in machining state, and when processing rocker arm, other devices or instrumental purpose are in rocker arm On external force easily rocker arm is caused to shake, and shaking force can be then finally transmitted on longitudinal screw 8, when longitudinal screw 8 by To shaking force influence when, curved-line thread path of the longitudinal screw 8 easily along longitudinal screw hole 7 rotates, and leads to the vertical of elevator 6 It changes to position, the lengthwise position so as to cause pressing plate 16 changes, and gag lever post 28 will insert in the limit of handwheel 9 at this time In the slot 29 of position, the turn of handwheel 9 is limited by the frictional force between gag lever post 28 and limiting slot 29, thus to longitudinal spiral shell Bar 8 is limited, and making the lengthwise position of pressing plate 16 is not in any change, guarantees stability when clamping rocker arm, in turn When handwheel, gag lever post 28 need to only be pullled by pull ring 30, be detached from gag lever post 28 out of limiting slot 29, handwheel 9 Just turn can be freely carried out, when the height of handwheel 9 changes, sliding shoe 19 can be adjusted accordingly by sliding cavity 20 Section keeps the position of gag lever post 28 opposite with limiting slot 29 always.

The one end opposite with limiting slot 29 of gag lever post 28 is equipped with positive magnetic sheet 33, and cathode in a ring is equipped in limiting slot 29 Magnetic sheet 34, cathode magnetic sheet 34 and positive magnetic sheet 33 are attracting, and the suction between cathode magnetic sheet 34 and positive magnetic sheet 33 can increase limit Friction level between position bar 28 and handwheel 9, to improve stability when handwheel 9 is limited the limitation of bar 28.

9 upper surface side of handwheel is equipped with lever 35 in a vertical shape, and the presence of lever 35 enables staff more easily Turn handwheel 9.
