Description

Technical Field

[0001] The utility model belongs to the technical field of rocker arm processing, and more specifically, particularly relates to a rocker arm arc surface processing device. Background Art

[0002] The rocker arm in the car is actually a double-arm lever, which is used to change the direction of the force transmitted from the push rod and act on the valve stem end to push the valve open. The ratio of the length of the two arms of the rocker arm is called the rocker arm ratio, which is about 1.2 to 1.8. The long arm end is used to push the valve. The working surface of the rocker arm head is generally made into a cylindrical shape. When the rocker arm swings, it can roll along the end face of the valve stem, so that the force between the two can act along the valve axis as much as possible.

[0003] When processing the curved surface of the rocker arm, it is necessary to put the rocker arm on the mounting seat and fix the top of the rocker arm and the side that does not need to be processed by hydraulic rods to avoid the rocker arm from offsetting and affecting the processing accuracy when the curved surface is processed. However, when the current rocker arm is put on the mounting seat, the size of the mounting seat is fixed, which is not convenient for fixing and processing rocker arms of different sizes. In addition, since the size of the rocker arm and the mounting seat used for the set matches, when the curved surface processing is completed, the rocker arm is often tightly stuck on the mounting seat, which is not convenient for disassembly, affecting the subsequent processing efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a rocker arm arc surface processing device is provided to achieve a more practical purpose. Utility Model Content

[0028] Among them, a third slide groove 14 is provided in the second slide groove 8, and the third slide groove 14 is connected with the second slide groove 7. A third slide groove 15 is slidably installed in the third slide groove 14. A connecting rod 16 is rotatably installed on the peripheral side of the top end of the third slide groove 15 at a position close to each second slide groove 8, and the other end of the connecting rod 16 is rotatably connected to the second slide groove 8. The third slide groove 15 moves up and down in the third slide groove 14, thereby driving the second slide groove 8 to move through the connecting rod 16. By the second slide groove 8 sliding back and forth in the second slide groove 7, rocker arms of different sizes can be tightened and fixed.

[0029] Among them, a first screw rod 17 is rotatably installed in the third slide groove 14, and the first screw rod 17 passes through the upper and lower ends of the third slider 15 and is threadedly connected to the third slider 15. The rotation of the first screw rod 17 drives the third slider 15 to slide up and down in the third slide groove 14.

[0030] A first motor 18 is installed at the bottom of the third slide groove 14 , and the output end of the first motor 18 is transmission-connected to the first screw 17 via a coupling. The first motor 18 drives the first screw 17 to rotate, thereby driving the third slider 15 to move.

[0035] The working principle of this embodiment is as follows: the staff first sets the rocker arm on the second mounting seat 6 so that the bottom end of the rocker arm fits with the top end of the limit ring 10, and then turns on the first motor 18, which drives the first screw 17 to rotate. The rotation of the first screw 17 drives the third slider 15 to slide up and down in the third slide groove 14, thereby driving the second slider 8 to move through the connecting rod 16. The back and forth sliding of the second slider 8 in the second slide groove 7 can tighten and fix rockers of different sizes. After fixing, the first hydraulic rod 12 and the second hydraulic rod 13 are controlled to extend respectively, and the side and the top end of the rocker arm that do not need to be polished are pressed and tightened. The second motor 20 is turned on to drive the second screw 19 to rotate, thereby driving the first slider 3 to move in the first slide groove 2, so that the rocker arm is moved to the position of the grinder 11 for grinding. During the grinding process, the second motor 20 is turned on to drive the first mounting seat 5 to rotate slightly to realize the processing of the curved surface of the rocker arm. After the processing is completed, the first hydraulic rod 12 and the second hydraulic rod 13 are controlled to retract, and the first motor 18 is turned on to drive the first screw 17 to rotate in the opposite direction, so that the arc-shaped fixing plate 9 holds the rocker arm tightly, which is convenient for quickly removing the processed rocker arm.
