detailed description

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

As shown in Figures 1 to 3, a roller bed assembly includes a base 1, and a cylinder 2 is installed horizontally at both ends of the base 1, and the piston rods of the two cylinders 2 are opposite and coaxially arranged. The mold head 3 is detachably connected and installed, and two roller brackets 4 are arranged in the middle between the two cylinders 2, and the roller brackets 4 are fixed on the base 1.

Both ends of the base 1 are provided with slide grooves 6 along the axial direction of the cylinder, and both sides of each cylinder 2 are fitted in the slide grooves 6 through the cylinder mounts 5 .

The top of the roller bracket 4 is a V-shaped groove 7, and the two sides of the roller bracket 4 are provided with a number of threaded holes 8 at equal intervals along the height direction, and the roller bracket 4 is fixed on the base by screws passing through the base 1 and cooperating with the threaded holes 8 1 on.

The steps to assemble the rollers using the assembled bed above are as follows:

Step 1. Assemble the bearing seat 11

Referring to FIG. 6 , the used installation die head 3 includes a cylindrical main body 31 , one end of the main body 31 is detachably connected to the end of the piston rod of the cylinder 2 , and the other end is provided with a cylindrical protrusion 32 .

Referring to Fig. 4 and Fig. 5, adjust the distance between the two air cylinders 2 and the height of the roller support 4 according to the specification of the roller to be installed. Place the roller 10 horizontally in the V-shaped groove 7 of the roller bracket 4, the bearing seat 11 is sleeved on the protrusion 32 of the mold head 3, the cylinder 2 works, and the two cylinders 2 push the bearing seat 11 to the middle at the same time , Push the bearing seat 11 into the two ends of the roller 10, so that the bearing seat 11 is assembled in place.

Step 2: Assemble the mandrel 12 and the bearing 13

Referring to FIG. 9 , the difference between the installed die head 3 used in step 1 is that a blind hole 33 matching the mandrel 12 is opened at the end of the protruding head 32 .

Referring to Fig. 7 and Fig. 8, first, manually assemble the bearing 13 at one end of the mandrel 12, insert the end of the mandrel 12 with the bearing 13 into the blind hole 33, and the side cylinder 2 works to push the mandrel 12 into the roller 10. Let the end of the mandrel 12 without bearings protrude from the bearing seat 11 at the other end, and then manually assemble the bearing 13 at this end, and then the two cylinders 2 work at the same time, so that the bearings 13 at both ends are pressed into the bearing seat 11 assembled in place.

Step 3. Assemble the labyrinth cover, sealing cover and retaining ring

The installation die head 3 used is the same as that in step one.

Referring to Fig. 10 and Fig. 11, firstly, the inner and outer labyrinth covers 14, 15 are manually assembled at both ends of the mandrel 12, and the cylinders 2 at both ends work simultaneously to press the inner and outer labyrinth covers 14, 15 into the bearing housing 11 and assemble them in place.

Next, seal covers 16 are manually assembled on both ends of the mandrel 12, and the cylinders 2 at both ends work simultaneously to press the seal covers 16 into the bearing housing 11 and assemble them in place.

Finally, manually assemble the retaining springs 17 at both ends of the mandrel 12, and the cylinders 2 at both ends work simultaneously to push the retaining springs 17 into the retaining grooves on the mandrel 12, which completes the assembly process of the roller.

Using this assembly bed for idler assembly is simple and convenient to operate, saves time and effort, and is low in cost, which greatly improves the production efficiency of workers. From the past assembly speed of 100 per person per day, it has now increased to an average of 150 per person per day. , effectively improving the production efficiency, and at the same time, the assembly accuracy can also be guaranteed.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
