Furthermore, a positioning bottom plate is arranged at the bottom of the positioning vertical plate, and the positioning bottom plate is perpendicular to the positioning vertical plate.

As a further improvement, two sliding grooves are formed in two sides of the positioning bottom plate, clamping blocks are inserted into the sliding grooves, protruding blocks are arranged on two sides of the positioning bottom plate, guide shafts are arranged on side faces of the protruding blocks, the protruding blocks can be sleeved on the guide shafts in a sliding mode, and springs are arranged on the guide shafts.

Furthermore, the sliding groove penetrates through the upper end and the lower end of the positioning bottom plate, and the extending direction of the sliding groove on the positioning bottom plate is parallel to the positioning vertical plate.

Furthermore, the bottom of the clamping block is provided with a positioning step matched with the top surface of the positioning bottom plate.

Advantageous effects

Compared with the prior art, the utility model discloses a camshaft assembly angle in right time frock's beneficial effect as follows: the timing angle tool for the camshaft assembly is reasonable in design, a camshaft timing gear can be assembled easily, and the timing of the gear is ensured accurately and unmistakably; the complex and tedious work of disassembling the gearbox and the flywheel shell and assembling and adjusting the gear train is avoided, the maintenance efficiency is greatly improved compared with the original method for disassembling the gearbox and the flywheel shell, and the production cost is greatly reduced.

Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

The specific implementation manner of the utility model is as follows: as shown in fig. 1-6, a timing angle tool for a camshaft assembly comprises a positioning vertical plate 1 adapted to the bottom surface of a cylinder cover 9, wherein a positioning pin 2 adapted to a pin hole 11 of a timing gear 10 on a camshaft 13 is arranged on the positioning vertical plate 1. In this camshaft assembly angle in right time frock, place location riser 1 on the bottom surface of the cylinder head 9 of putting upside down, locating pin 2 and the pinhole 11 looks adaptation of timing gear 10 on the camshaft 13, and lateral shifting location riser 1 and rotatory camshaft 13 make locating pin 2, pinhole 11 and camshaft 13, the central line coplane of timing gear 10, locating camshaft 13 through setting up of the high position of locating pin 2, the installation angle of timing gear 10, can confirm that the installation angle of camshaft 13 and timing gear 10 is correct this moment, can carry out the accuracy installation with other gears and timing gear 10 meshing, this frock is quick to timing gear 10 installation, the angle installation is accurate, high production efficiency, low in manufacturing cost.

In this embodiment, the bottom of the vertical positioning plate 1 is provided with a positioning bottom plate 3, the positioning bottom plate 3 is perpendicular to the vertical positioning plate 1, and the positioning bottom plate 3 is erected on the bottom surface of the cylinder cover 9, so that the vertical positioning plate 1 is ensured not to incline.
