Description
Technical Field
The utility model relates to a processing equipment of back brake cam rocking arm, especially a back brake cam rocking arm weld nut frock.
Background
The installation between back braking cam rocking arm and the camshaft needs to be locked with the bolt, and the bolt cooperatees with the nut, and bolt and nut just assemble on the rocking arm when back braking cam rocking arm is installed generally speaking, however the time is a long time, and the nut can take place to loosen under the influence of vibrations or other factors, drops from the bolt to the installation of back braking cam rocking arm is influenced. Aiming at the situation, the nut can be welded at the corresponding position of the rear brake cam rocker arm to avoid the nut from falling off, but no tooling specially used for welding the nut of the rear brake cam rocker arm is arranged on the market at present, so that the nut is inconvenient to weld.
Disclosure of Invention
To the problem that exists among the prior art, the utility model provides a back braking cam rocking arm welds nut frock is used for the nut welding of back braking cam rocking arm specially.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a back braking cam rocking arm welds nut frock, includes the bottom plate, be equipped with on the bottom plate and fix rocking arm fixing base and mobilizable nut dead lever on its terminal surface, be equipped with on the rocking arm fixing base and insert the fixed inserted bar of rocking arm of establishing in the rocking arm shaft hole, the fixed inserted bar of rocking arm is perpendicular and the two dislocation with the nut dead lever, the bottom plate corresponds the nut dead lever and is equipped with corresponding jack, the nut dead lever is including the section of gripping, grafting section and the nut fixed segment that sets gradually, the grafting section cooperatees with the jack, the nut fixed segment is equipped with the external screw thread with the nut adaptation for the other end of being connected one end with the grafting section.
Adopt above-mentioned technical scheme, the grafting cooperation between its shaft hole of rocking arm accessible and the fixed inserted bar of rocking arm is fixed in rocking arm fixing base department, then insert the nut dead lever in the jack, make grafting section and jack cooperate, make the nut fixed section pass the position of preparing welded nut on the rocking arm simultaneously, the nut that will prepare is connected through screw-thread fit with the nut fixed section after that, make the nut installed on the nut dead lever, just so come to fix a position the nut with regard to the accessible operating nut dead lever, solve the fixed problem of nut in welding process.
Furthermore, the bottom plate is also provided with a rocker cushion block, and the rocker cushion block and the bottom plate are detachably mounted.
By adopting the technical scheme, the rocker cushion block can provide support for the rocker, one end of the rocker is fixed by the rocker fixing inserted link when in use, and the other end of the rocker is cushioned by the rocker cushion block, so that the phenomenon that the welding effect of the nut is influenced due to unstable gravity center of the rocker and shaking is avoided; the different rocking arm cushion blocks that need the adaptation of rocking arm size are different, and the setting can be dismantled to the rocking arm cushion block, is convenient for change the rocking arm cushion block.
Furthermore, a mounting slot is formed in the position, corresponding to the rocker cushion block, of the bottom plate, and the rocker cushion block is inserted into the mounting slot.
Adopt above-mentioned technical scheme, set up like this and make the rocking arm cushion can dismantle with the bottom plate through the grafting cooperation with the installation slot and be connected to be convenient for the change of rocking arm cushion.
Furthermore, the installation slot is provided with an installation opening at one side of the extension direction of the installation slot.
By adopting the technical scheme, the rocker cushion block enters the installation slot from the installation port and is in plug-in fit with the installation slot, so that the rocker cushion block is convenient to install.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the present invention.
Detailed Description
The following will further describe the embodiments of the present invention with reference to the drawings and examples.
As shown in fig. 1-2, a back brake cam rocker arm welds nut frock, including bottom plate 1, be equipped with rocker arm fixing base 2 and mobilizable nut dead lever 3 of fixing on its terminal surface on bottom plate 1, be equipped with the fixed inserted bar 21 of rocker arm that can insert and establish in rocker arm shaft hole 71 on the rocker arm fixing base 2, the fixed inserted bar 21 of rocker arm is perpendicular and the two dislocation with nut dead lever 3, bottom plate 1 corresponds nut dead lever 3 and is equipped with corresponding jack 11, nut dead lever 3 is including the section of gripping 31, grafting section 32 and the nut fixed section 33 that set gradually, and the size of above-mentioned three cross section diminishes step by step, grafting section 32 cooperatees with jack 11, nut fixed section 33 is equipped with the external screw thread 331 with nut 8 adaptation for the other end of being connected one end with grafting section 32. Rocker 7 accessible its shaft hole 71 and the fixed inserted bar 21 of rocker between the grafting cooperation and be fixed in rocker fixing base 2 department, then insert in jack 11 with nut fixed rod 3, make grafting section 32 and jack 11 cooperate, make nut fixed segment 33 pass the position of preparing welded nut 8 on the rocker 7 simultaneously, nut 8 that will prepare is connected through screw-thread fit with nut fixed segment 33 after that, make nut 8 be installed on nut fixed rod 3, just so accessible operation nut fixed rod 3 fixes a position nut 8, solve the fixed problem of nut 8 in welding process.
The base plate 1 is further provided with a rocker cushion block 4, and the rocker cushion block 4 and the base plate 1 are detachably mounted. The rocker cushion block 4 can provide support for the rocker arm 7, one end of the rocker arm 7 is fixed by the rocker arm fixing inserted link 21 when the welding tool is used, and the other end of the rocker arm 7 is cushioned by the rocker cushion block 4, so that the welding effect of the nut 8 is prevented from being influenced due to unstable gravity center of the rocker arm 7 and shaking; the different rocking arm cushion 4 that needs the different adaptation of the size of rocking arm 7, rocking arm cushion 4 can be dismantled and set up, is convenient for change rocking arm cushion 4.
