Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments.
As shown in fig. 1 and 2, the assembling tool for the camshaft of the diesel engine is provided with a guide shaft 3 which is screwed at one end of a camshaft 4; referring to fig. 4, one end of the guide shaft 3 has a small diameter shaft 33 having a diameter smaller than that of the guide shaft; the small-diameter shaft 33 is coaxially arranged with the guide shaft 3; the end of the small-diameter shaft 33 is provided with a connecting shaft 31 in threaded connection with the camshaft; the diameter of the connecting shaft 31 is the same as that of the guide shaft 3, and the connecting shaft, the guide shaft 2 and the small-diameter shaft 33 are coaxially arranged; the total length of the small diameter shaft 33 and the guide shaft 3 is at least longer than the length of one supporting camshaft journal; one end of the guide shaft 3 is in threaded connection with the camshaft 4 through a connecting shaft 31; the other end of the guide shaft 3 is sleeved with a guide pipe 21 which is used for supporting the camshaft and preventing the camshaft journal which is not screwed in from colliding with the engine body; the length of the conduit 21 is at least greater than the length of one supporting camshaft journal; with reference to fig. 3, the diameter of the guide tube 21 is greater than the diameter of the camshaft 4; one end of the guide tube 21 is sleeved on the guide shaft 3, and the guide shaft 3 can axially move in the guide tube 21; the other end of the conduit 31 is provided with a flange 23 for connecting with the body; camshaft 4 pass through guiding shaft 3 and pipe 21 with organism 1 be connected, because the existence of guiding shaft, can not lead to the camshaft axle journal of screw in to collide with the organism, through the setoff because the pipe, can not lead to the camshaft axle journal of not screw in to collide with the organism yet, so can be safe install the camshaft in organism camshaft shaft hole to the camshaft.
And the center of the end face of the other end of the guide shaft is provided with a weight removing part 34.
A camshaft end threaded hole is formed in the end part of the camshaft 4; the connecting shaft 31 is provided with threaded holes matched with the positions, sizes and numbers of the threaded holes at the end of the camshaft; the connecting shaft and the camshaft are connected into a whole through the double-end stud.
The outer diameter surface of the guide pipe 21 is provided with a plurality of observation windows 22 which are uniformly distributed along the circumference, and the main function is to observe the installation condition of the camshaft in the process of installing the camshaft.
The flange 23 is provided with unthreaded holes matched with the position size and the number of the threaded holes in the shaft hole of the camshaft of the engine body, and process bolts penetrate through the holes of the sleeve flange and are fixed to the threaded holes in the shaft hole of the camshaft of the engine body.
The process bolts are used to pass through the holes 24 of the flange 23 of the sleeve 2 and are fixed to the threaded holes 12 at the shaft hole 11 of the camshaft 4 of the machine body 1. Use short bolt 6 to install connecting axle screw hole 32 from step shaft 33, reuse stud 5 to twist respectively 4 end screw holes of camshaft and connecting axle 31 screw hole 32, couple together camshaft 4 and guiding axle 3, then take camshaft 4 to pass pipe 2 screw in to 1 shaft hole 11 department of organism to guiding axle 3, on the one hand because the existence of guiding axle 3, can not lead to 4 journals of camshaft of screw in to collide with organism 1, on the other hand is again because the backing of pipe 2, can not lead to 4 journals of camshaft that do not screw in to collide with organism 1 yet, so can be safe install 1 camshaft shaft hole to organism 4.
This instrument forms according to camshaft structural design itself, and the operation is more convenient, the clash injury problem that appears in the solution camshaft installation that can be fine.
