CN203390807U - Double-overhead-cam-shaft timing positioning tooling - Google Patents

Abstract

The utility model discloses a double-overhead-cam-shaft timing positioning tooling, which mainly consists of a V-shaped block (2), a guide block (5) and two trapezoidal blocks (1) which are arranged on a bottom plate (4), wherein the two trapezoidal blocks (1) and the V-shaped block (2) are arranged on one guide block (5), the two trapezoidal blocks (1) are respectively positioned at the two sides of the V-shaped block (2), then, two cylindrical pins (6) are arranged in two pin holes of the guide block (5) for limiting the position, and a screw bolt (3) passes through the V-shaped block (2) to be screwed into a screw hole of the guide block (5) for forming an movable whole body. The double-overhead-cam-shaft timing positioning tooling solves the problem that in the existing engine assembly process, the cam shaft timing control is difficult. The correct timing positioning in the engine assembly process can be ensured.

Description

A kind of Dual Over Head Camshaft timing positioning tool

Technical field

The utility model belongs to engine assembly technical field, and especially a kind of Dual Over Head Camshaft timing positioning tool, is mainly the timing of guaranteeing that camshaft is correct.

Background technology

In engine assembly process, in the time of must guaranteeing to assemble, inlet and outlet camshaft timing be correct.Because current techniques does not have appropriate frock to guarantee camshaft timing, during for solution engine assembly, camshaft timing is difficult to ensure the problem of card, needs a kind of frock of design, to guarantee correct camshaft timing, meets installation requirement.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, a kind of Dual Over Head Camshaft timing positioning tool is provided, solved in present engine assembling process, the problem that camshaft timing control ratio is more difficult, guarantee has correct timing location in engine assembly process.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals to realize: a kind of Dual Over Head Camshaft timing positioning tool, by the vee-block (2), guide pad (5) and two trapezoid blocks (1) that are arranged on base plate (4), formed, with vee-block (2) is arranged on a guide pad, vee-block (2) is positioned between two trapezoid blocks (1).

Described vee-block (2) is connected with guide pad (5) by bolt (3), straight pin (6).

Owing to adopting technique scheme, the utility model provides has such beneficial effect:

1. the utility model can effectively guarantee effectively correct timing in engine assembly process, greatly reduces engine assembly process convexity wheel shaft timing positioning difficulty;

2. the utility model can increase substantially operating efficiency, no matter be model machine assembling or batch production, all can effectively reduce the installation time;

3. the utility model is simple in structure, cheap, and can compensate the gap increase causing because of wearing and tearing, therefore can repeatedly use, and reduces assembly tooling cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model,

Fig. 2 is structure cutaway view of the present utility model.

In figure: 1-trapezoid block, 2-V shape piece, 3-bolt, 4-base plate, 5-guide pad, 6-straight pin.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in further detail.

As Fig. 1-2, a kind of Dual Over Head Camshaft timing positioning tool, it is a kind of new frock of guaranteeing correct timing, by two trapezoid blocks (1), a vee-block (2), a guide pad (5), a base plate (4), a bolt (3) and two straight pins (6) form, during for engine assembly, enter, the timing location of exhaust cam shaft, by base plate (4) conduct, supported, two trapezoid blocks (1) are contained on same guide pad (5), rotate tight a bolt (3), when vee-block (2) moves down, two trapezoid blocks (1) expand outwardly simultaneously, broaden, stuckly enter, exhaust cam shaft locating surface, guarantee when fastening camshaft chain bolt, camshaft must not rotate, guarantee that camshaft timing is correct.

Claims (3)

1. a Dual Over Head Camshaft timing positioning tool, it is characterized in that, by the vee-block (2), guide pad (5) and two trapezoid blocks (1) that are arranged on base plate (4), formed, the timing of inlet and outlet camshaft location during for engine assembly, it is upper that two trapezoid blocks (1) and vee-block (2) are arranged on same guide pad (5), and vee-block (2) is positioned between two trapezoid blocks (1); When rotation tights a bolt (3), vee-block (2) moves down, and two trapezoid blocks (1) expand outwardly simultaneously, and stuck inlet and outlet camshaft locating surface guarantees that camshaft must not rotate when fastening camshaft chain bolt, guarantees that camshaft timing is correct.

2. a kind of Dual Over Head Camshaft timing positioning tool according to claim 1, is characterized in that, described vee-block (2) is connected with guide pad (5) by bolt (3), straight pin (6).

3. a kind of Dual Over Head Camshaft timing positioning tool according to claim 1, is characterized in that, described two trapezoid blocks (1) are contained on same guide pad (5).
