Description

Forging roll chela processing tool

Technical field

The utility model belongs to connection rod of automobile engine forging field, and in particular to a kind of forging roll chela processing tool.

Background technique

Automobile engine is that the machine of power is provided for automobile, is the heart of automobile, influences dynamic property, the economy of automobile And the feature of environmental protection, and the power of engine then derives from cylinder interior.Cylinder, which is exactly one, can be converted into the interior of fuel The place of kinetic energy can be simply interpreted as, and fuel generates immense pressure and push piston up-down, pass through in combustor inner cylinder Power is transmitted to crankshaft by connecting rod, is eventually converted into rotary motion, then by speed changer and transmission shaft, power is transmitted to driving wheel On, so that automobile be pushed to advance.Since the working principle of engine is similar, basic structure is also just similar.Petrol engine Usually two great institutions five big systems composition, is crank link mechanism respectively, valve actuating mechanism, fuel system, lube system, cooling system, Igniting system, starts system.Wherein connecting rod is one of main transmission mechanism of automobile engine, it connects piston and crankshaft, The expanding gas pressure for acting on top land is transmitted to crankshaft, the linear reciprocating motion of piston is made to be reversibly converted to crankshaft Rotary motion, with output power.

Since engine link is vulnerable part, so the forging roll chela requirement pole for forging connection rod of automobile engine Its is huge, needs in production a large amount of spare.It is the consistency for guaranteeing a pair of of chela when processing forging roll chela, a pair of of chela needs It wants integral type to process, is cut again after processing, above-mentioned processing method positioning is relatively difficult, it is difficult to ensure that machining accuracy, and And the requirement to operator is also very high, it is necessary to have the experience of very abundant could be grasped, and therefore, how guarantee a pair The precision that its positioning process is also ensured under the premise of the consistency of chela, make it have certain repeatability etc. be at present urgently It solves the problems, such as.

Utility model content

The purpose of this utility model is that in view of the deficiencies of the prior art, it is simple to provide a kind of structure, easy to operate, error It is small, a kind of high forging roll chela processing tool of setting accuracy on work.

The purpose of this utility model is achieved in that a kind of forging roll chela processing tool, it is characterised in that: the processing Tooling includes tooling main body, two adjusting bolts and forging roll chela, and the tooling main body is cylindrical, the tooling main body Center is machined with one for placing the rectangle mounting groove of forging roll chela, and the depth of the mounting groove is clamped greater than forging roll The height of positioning clamping column below pawl, four edges of the rectangle mounting groove are machined with respectively for preventing from scratching roll forging The middle position of the avoid holes of machine chela, the orthogonal two sides of mounting groove is respectively equipped with a bolt hole, the spiral shell Keyhole is the through-hole that the inner wall of mounting groove is extended to from the outer wall of tooling main body, set in two bolts hole there are two adjust Bolt is saved, bolt is adjusted and is in contact across the bolt hole with the forging roll chela in the rectangle mounting groove.

The advantages and positive effects of the utility model are as follows: this forging roll chela tool structure for processing is simple, practical side is operated Just, at low cost, the precision of its positioning process is also ensured while improving working efficiency, more avoids the original because of artificial The error because caused by.

Detailed description of the invention

Fig. 2 is the top view of tooling main body in the utility model Fig. 1.

Fig. 3 is the use state of the utility model with reference to figure.

Specific embodiment

The application specific embodiment is described in detail with reference to the accompanying drawing:

As shown in Figure 1, which includes 1, two adjusting bolt 5 of tooling main body and forging roll chela 7, the tooling Main body 1 is cylindrical, and the center of the tooling main body 1 is machined with a rectangle for placing forging roll chela 7 and installs Slot 2, the depth of the mounting groove 2 are greater than the height of the positioning clamping column 6 of 7 lower section of forging roll chela, the rectangle mounting groove 2 Four edges are machined with the avoid holes 3 for preventing from scratching forging roll chela 7, the mounting groove 2 orthogonal two respectively The middle position of side is respectively equipped with a bolt hole 4, and the bolt hole 4 is to extend to mounting groove 2 from the outer wall of tooling main body 1 Inner wall a through-hole, set in described two bolts hole 4 there are two bolt 5 is adjusted, adjust bolt 5 and pass through the bolt hole 4 It is in contact with the forging roll chela 7 in the rectangle mounting groove 2, by adjusting 5 pairs of forging rolls being arranged in mounting groove 2 of bolt Chela 7 is adjusted and clamps, and the upper end two sides short side edge of the mounting groove 2 is machined with 45 ° of chamferings, in favor of forging roll pincers Pawl 7 is taken.

As shown in Figures 2 and 3, in processing, the positioning clamping column 6 of forging roll chela 7 is first put into tooling main body 1 downward Mounting groove 2 in, forging roll is clamped by adjusting bolt 5 that the middle position of the orthogonal two sides of mounting groove 2 is equipped with Pawl 7 is adjusted, and since the depth of mounting groove 2 is greater than the height of the positioning clamping column 6 of 7 lower section of forging roll chela, and makes chela Body 8 is preferably bonded with four walls of mounting groove 2, to reach preferably positioning effect under the action of mounting groove 2 and adjustment bolt 5 Fruit.
