Description

A tool for processing rocker fork

technical field

The invention relates to designing a tooling, in particular to a tooling for processing a fork of a rocker arm.

Background technique

In the prior art, the processing of the fork of the rocker arm is often involved. Referring to FIG. 1 , this rocker arm part 1 is a die forging with two forks and the center lines of the two forks are angled. When processing the rocker arm yoke, the prior art generally realizes the processing of the rocker arm yoke by scribing and temporarily assembling the combination fixture. This kind of processing method takes a long time to assemble the combined fixture, the quality is unstable, and the quality problem that the processing deviates from the marking line is prone to occur, and the processing efficiency is low.

Contents of the invention

The object of the present invention is to provide a tool for processing the yoke of a rocker arm.

The technical solution of the present invention is: a tool for processing the yoke of a rocker arm, the rocker arm part has a shaft hole; the tool includes a mounting plate 2, a positioning block 3, a positioning adjustment screw 4, a fixing block 5, a fixing Screw 6, positioning shaft 7 and fastening nut 8; described positioning block 3 has two threaded holes 10; described fixed block 5 has a threaded hole 13; described positioning adjusting screw 4 has two, And match with two threaded holes of positioning block respectively; Described set screw matches with the threaded hole of fixed block; Described positioning shaft 7 is fixed on the mounting plate 2, and positioning shaft 7 top has external thread 11, and the bottom is Polished rod matches with fastening nut 8 and positioning shaft external thread.

Further, the rocker arm at both ends of the rocker arm part 1 is at a certain angle.

Further, the two ends of the rocker arm part 1 are lugs.

Further, the mounting plate is connected with a damping block, a damping rod or a buffer rod for eliminating the vibration of the mounting plate during processing.

Further, the positioning block and the fixing block can slide on the mounting plate.

Further, the positioning adjustment screw and the fixing screw are located on the same plane.

When positioning and installing, put the rotating shaft hole of the rocker arm on the positioning shaft 7, so that the rocker arm is located at the polished rod part of the positioning shaft 7; rotate the fastening nut 8, so that the fastening nut 8 is pressed on the rocker arm, so that the rocker arm Firmly fixed on the mounting plate 2.

The invention has the beneficial effects of simple operation, simple mechanism, convenient implementation and high work efficiency.

Description of drawings

Fig. 1 is: the structural representation of rocker arm of the present invention;

Among the figure: 1 is the rocker arm part, 2 is the mounting plate, 3 is the positioning block, 4 is the positioning adjustment screw, 5 is the fixing block, 6 is the fixing screw, 7 is the positioning shaft, and 8 is the fastening nut.

Detailed ways

The technical solution will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Provide a kind of tooling for processing the yoke of the rocker arm, the rocker arm part has a shaft hole; the tooling includes a mounting plate 2, a positioning block 3, a positioning adjustment screw 4, a fixing block 5, a fixing screw 6, and a positioning shaft 7 and fastening nut 8; the positioning block 3 has two threaded holes 10; the fixed block 5 has a threaded hole 13; the positioning adjustment screw 4 has two, and respectively with the positioning block The two threaded holes are matched; the fixing screw is matched with the threaded hole of the fixed block; the positioning shaft 7 is fixed on the mounting plate 2, and the positioning shaft 7 has an external thread 11 on the top, and the bottom is a polished rod, which is connected with the fastening nut 8 matches with the external thread of the positioning shaft.

Further, the rocker arm at both ends of the rocker arm part 1 is at a certain angle.
