Description

Technical Field

[0001] This utility model relates to the field of rocker arm bolt assembly technology, specifically to an engine rocker arm slot bolt assembly device. Background Technology

[0002] The brake lever is operated by the rotating vanes of the camshaft, which raise or lower one end, while the other end acts on the valve stem. When the camshaft vanes raise the outer lever, the internal force presses against the valve stem, opening the valve. When the outer lever is allowed to return due to the action of the camshaft, the inner lever rises, allowing the valve spring to compress and close the valve.

[0003] A threaded hole is provided at one end of the rocker arm, and a rocker arm bolt is threaded into the threaded hole. A rocker arm nut is also threaded onto the outside of the rocker arm bolt. During actual installation, the worker holds an electric screwdriver in one hand and the rocker arm in the other, and uses the electric screwdriver to drive the rocker arm bolt into the threaded hole of the rocker arm. If the rocker arm is not held firmly enough, the rotation of the electric screwdriver will cause the rocker arm to jump, which may injure the hand. Utility Model Content

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 An engine rocker arm slot bolt assembly device includes a base 1, a base support 2 fixedly mounted on the top of the base 1, and an upper pressure plate 4 movably mounted on the top of the base support 2 via a hinge shaft 3. The length of the base support 2 is greater than the length of the upper pressure plate 4. A torsion spring 5 is fitted on the outside of the hinge shaft 3. One end of the torsion spring 5 presses against the base support 2, and the other end of the torsion spring 5 presses against the upper pressure plate 4. The upper pressure plate 4, which is not in the locked state, can be popped open by the torsion spring 5.

[0015] Please see Figure 1-4 A rocker arm 6 is provided between the base platform 2 and the upper pressure platform 4. One end of the rocker arm 6 is threadedly connected to a rocker arm bolt 7, which extends upward to one side of the upper pressure platform 4. A rocker arm nut 8 is threadedly connected to the outer side of the rocker arm bolt 7. The rocker arm 6, rocker arm bolt 7, and rocker arm nut 8 are existing known technologies and will not be described in detail.

[0016] Please see Figure 1-4 The bottom of the upper pressure platform 4 is provided with an upper rocker arm groove 9 corresponding to the rocker arm 6, and the surface of the bottom support platform 2 is provided with a lower rocker arm groove 10 corresponding to the rocker arm 6. The rocker arm 6 is engaged between the bottom support platform 2 and the upper pressure platform 4 through the upper rocker arm groove 9 and the lower rocker arm groove 10. The front of the surface of the bottom support platform 2 is provided with a nut step groove 11 corresponding to the rocker arm nut 8. The rocker arm nut 8 is confined in the inside of the nut step groove 11, and the bottom of the rocker arm bolt 7 extends downward into the inside of the nut step groove 11.

[0017] Please see Figure 1-4 Both the base support 2 and the upper pressure platform 4 have protruding pillars 12 fixedly installed on their surfaces. A pneumatic rod 13 is hinged between the upper and lower protruding pillars 12. When the upper pressure platform 4 rotates 90 degrees to open, it is supported by the opening of the pneumatic rod 13. Conversely, when the upper pressure platform 4 rotates 90 degrees to close, it is limited by the pneumatic rod 13. L-shaped elastic plates 14 are fixedly installed on the front and back of the base support 2. The top of the L-shaped elastic plate 14 has an inclined surface, and the bottom of the upper pressure platform 4 has a tangent surface parallel to the inclined surface. When the upper pressure platform 4 rotates and presses down, the tangent surface and the inclined surface squeeze against each other, which can open the L-shaped elastic plate 14 to both sides.

[0018] Please see Figure 1-4The outer wall of the L-shaped elastic plate 14 is fitted with a locking nut 15. The locking nut 15 is internally threaded with a collet 16. One end of the collet 16 has an internal hexagonal groove, and the other end of the collet 16 is hemispherical. The collet 16 can be driven forward in the locking nut 15 through the internal hexagonal groove, thereby controlling the depth of the collet 16 inserted into the slot 17. The outer wall of the upper pressure platform 4 has a slot 17 corresponding to the collet 16. The L-shaped elastic plate 14 is engaged with the upper pressure platform 4 through the locking nut 15, the collet 16 and the slot 17, thereby controlling the locking between the bottom support platform 2 and the upper pressure platform 4 and fixing the position of the rocker arm 6.

[0019] Working principle: In use, the rocker arm 6 is placed in the lower rocker arm groove 10 on the surface of the base plate 2, and the rocker arm nut 8 is placed in the nut step groove 11. Then, the upper pressure plate 4 is driven to rotate around the hinge shaft 3. The upper rocker arm groove 9 of the upper pressure plate 4 will match the top of the rocker arm 6. At the same time, the pneumatic rod 13 will also retract and limit the upper pressure plate 4. Meanwhile, the L-shaped elastic plate 14 will push the chuck 16 to insert into the slot 17, thereby locking the upper pressure plate 4 and the base plate 2 and fixing the rocker arm 6. This makes it convenient to use an electric screwdriver to assemble the rocker arm bolt 7 into the threaded hole of the rocker arm 6.

[0020] Conversely, the upper pressure table 4 is driven to rotate in the opposite direction to open, the pneumatic rod 13 is extended, the locking head 16 and the locking slot 17 are unlocked, and then the assembled rocker arm 6 can be moved in and out to be taken out.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
