Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Fixed gear device of the present invention designs mainly for the cogged parts of band carry out tightening of wheel gear locking nut, the present embodiment is described in detail for the steering pump in engine, generally, steering pump gear is arranged on steering pump gear shaft in advance, integral installation is on the engine again for the general and gear shaft spline fitted of steering pump gear, be arranged on after on steering pump gear shaft at steering pump gear, wheel gear locking nut has upper torque requirement, when tightening wheel gear locking nut, need fixed gear shaft, to reach the object of upper moment.Fixed gear device provided by the invention is rotated by fixed gear exactly, indirectly realizes fixing gear shaft, and then tightens wheel gear locking nut.
As shown in Figures 1 and 2, the fixed gear device that the present embodiment provides, by being provided with main panel 11 in fixed mount 1 upper end, main panel 11 side is provided with gear axle journal and steps down breach 111, main panel 11 is provided with two gear position limiting blocks 12 and fixture block 2, the axle journal of steering pump pushes gear axle journal and to step down breach 111, gear inner face is just connected on main panel 11, two gear position limiting blocks 12 and fixture block 2 shape mated gear 62(are see Fig. 4) three-point fix, engage by the card base (21,21a) on fixture block 2 object reaching and pin gear and rotate with gear teeth simultaneously.
Particularly, in such scheme, main panel 11 is fixed on base 14 by support bar 13, the similar U-shaped structure (see Fig. 3) of base, and support bar 13 two ends are fixed by nut and base 14 and main panel 11, and base 14 is also bolted on workbench 5.Gear axle journal breach 111 of stepping down is located at main panel near manually-operated side, convenient manually steering pump pushed this gear axle journal and to step down in breach 111 and to make gear inner face be connected on main panel 11, two gear position limiting blocks 12 are located at the main panel upper surface that gear axle journal is stepped down around breach 111, concrete setting position ensures the three-point fix of two gear position limiting blocks 12 and fixture block 2 shape mated gear, in the present embodiment, two gear position limiting blocks 12 are located at gear axle journal and step down the left side of breach 111 and top side, fixture block 2 is located at gear axle journal and steps down the right side of breach 111, two gear position limiting blocks 12 can become for nylon, especially by being bolted on main panel 11.
Fixture block 2 is located at by rotating shaft 23 the main panel upper surface that gear axle journal steps down on the right side of breach 111, the two ends of fixture block 2 are provided with and rotate forward card base 21 and reversion card base 21a, rotate forward card base 21 to be symmetrical arranged with reversion card base 21a, rotate forward card base 21, with reversion card base 21a, all there is a support zone 22 coordinated with gear teeth facing, when rotating fixture block 2 and making the support zone rotating forward card base 21 be connected to gear teeth rotating forward face, gear forward pins, when rotating fixture block 2 and making the support zone of reversion card base 21a be connected to gear teeth reversion face, gear oppositely pins.Be connected on gear teeth facing to make the support zone on card base, also comprise a spring 3, one end of spring 3 is fixedly connected with fixture block 2, the other end of spring 3 is fixed on main panel 11, particularly, between two card bases on fixture block 2, position is provided with fixed bar 31, main panel 11 is provided with spring fixed axis 32, spring 3 two ends are connected with spring fixed axis 32 with fixed bar 31 respectively, when fixture block 2 is in poised state, the center line of spring 3 is through the center of the rotating shaft 23 of fixture block 2, now, the center of rotating shaft 23 is between fixed bar 31 and spring fixed axis 32, when positive and negative rotation fixture block 2, fixture block 2 disequilibrium rotates around rotating shaft 23, and spring 3 is in tensioning state, the support zone that the tension force of spring 3 makes the support zone rotating forward card base 21 be connected to gear teeth rotating forward face (see Fig. 5) or reversion card base 21a is connected to gear teeth reversion face (see Fig. 6).
Too near and then interfere pushing of steering pump in order to prevent the card base of fixture block 2 from rotating apart from gear axle journal breach distance of stepping down, fixture block 2 rotates within the specific limits around rotating shaft 23, particularly, the spacer pin 4 that restriction fixture block rotates is provided with at the main panel upper surface place near fixture block 2, in the present embodiment, the set bolt of main panel 11 also can play the effect being similar to spacer pin 4, when fixture block 2 is along B to when rotating (see Fig. 5) to certain position, spacer pin 4 stops it to continue to rotate, on the contrary, the set bolt of the close fixture block 2 of main panel 11 also stops fixture block 2 to continue to rotate to the opposite direction of B.
As shown in Figure 4, when concrete this device of use, first, by bolt, this device is fixed on (see Fig. 2) on work top.Secondly, gear 62 is contained on the gear shaft 61 of steering pump 6, push make the inner surface of gear 62 be connected on main panel 11 along gear axle journal breach 111 opening direction of stepping down after wheel gear locking nut 63 pretension, after fixture block 2 encountered by gear, fixture block 2 23 to rotate clockwise around the shaft (see Fig. 5 B to), under the tension force effect of spring 3, fixture block 2 self-return, the support zone 22 of the rotating forward card base 21 on fixture block 2 is connected to certain gear teeth and rotates forward face (see Fig. 5), by moment on torque spanner, rotate clockwise, the oriented trend rotated clockwise of gear 62, promote the trend that fixture block 2 rotates counterclockwise, gear 62 and fixture block 2 are formed and are automatically locked.
In like manner, when needing to unclamp wheel gear locking nut moment, fixture block 2 is toggled it to limited block 4 place clockwise, under the tension force effect of spring 3, fixture block 2 gear that is automatically locked rotates counterclockwise, and meets the condition of the locking nut moment that gets loose counterclockwise.Finally, steering pump upwards mentions certain distance, and gear 62 and fixture block 2 misplace and depart from, and steering pump freely can take out and lift down from this device.
Gear fixing device of the present invention is by arranging the fixture block of flexible rotating, there is the advantage of the gear that is automatically locked, fixture block is under the tension of spring, can rotate freely in certain space around the shaft, one direction is stepped down to gear, the locked gear of one direction, the position of fixture block is stirred, can realize clockwise and counterclockwise between locked conversion.Meanwhile, this apparatus structure is simple, and manufacturing process is succinct, only needs simple car, brill, cuts with scissors, attacks, welds and can complete processing and manufacturing, cost-saving, and, quick and convenient installation steering pump gear can be realized, raise the efficiency, reduce process consumption, reduce labour intensity.
Be only specific embodiments of the invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
