Technical scheme is as follows:

In a kind of high line, roll ∮ 495 roll fixtures, comprise ∮ 495 roll fixtures, the side wall ends of described ∮ 495 roll fixtures is provided with four symmetrical claw planes, on the sidewall of described ∮ 495 roll fixtures, has top wire hole, and described ∮ 495 roll fixtures are provided with inner chamber; Described top wire hole has internal thread, and jackscrew is contained on described top wire hole, and described jackscrew has external screw thread; The diameter of described ∮ 495 roll fixtures is 290mm, and the diameter of described inner chamber is 240mm, and the distance between upper and lower two described claw planes is 276mm.

Further: the length of described ∮ 495 roll fixtures is 230mm, the center line of described top wire hole is 180mm to the distance of described ∮ 495 roll clamp ends, and the length of described claw plane is 160mm.

Further: on the sidewall of described roll fixture, to have two described top wire holes.

Further: the shape of the shape of described inner chamber and roller head adapts.

Further: the structure of described jackscrew comprises jackscrew cap, jackscrew bar and jackscrew head, described jackscrew cap and described jackscrew head lay respectively at described jackscrew bar two ends.

Further: the jackscrew that described jackscrew is M30, the height of described jackscrew cap is 22mm, and the length of described jackscrew bar is 55mm, and the whole height of described jackscrew is 80mm.

Compared with prior art, technique effect of the present utility model comprises:

1, in the high line of the utility model, roll ∮ 495 roll fixtures and be applicable to CA8450 and two kinds of model lathes of CA8463, both improved the machining accuracy of CA8450 and two kinds of roll lathes of CA8463, can bear again the processing torsion producing in Roller Machining, there is enough rigidity and intensity, roll fixture is convenient in processing roll use procedure, practical, durable, improve the working ability of roll lathe, met the Production requirement of high line.

2, remarkable in economical benefits.

Use of the present utility model, saves and to purchase 1,200,000 yuan of novel lathe funds, has met the demand that our factory is produced, easy accessibility in use, and technical performance is reliable, in new peak line year more than 200,000,000 yuan of wound benefits, plays an important role.

Accompanying drawing explanation

Fig. 1 is the front view of ∮ 495 roll fixtures in the utility model;

Fig. 2 be in the utility model A-A to profile;

Fig. 3 is the structure chart of jackscrew in the utility model.

The specific embodiment

Below with reference to accompanying drawing and preferred embodiment, the technical solution of the utility model is elaborated.

As shown in Figure 1, be the front view of ∮ 495 roll fixtures in the utility model; As shown in Figure 2, be in the utility model A-A to profile; As shown in Figure 3, be the structure chart of jackscrew in the utility model.

The side wall ends of ∮ 495 roll fixtures 1 is provided with four symmetrical claw planes 11, has two top wire holes 12 on sidewall, in the middle of ∮ 495 roll fixtures 1, is inner chamber 13.The shape of the shape of inner chamber 13 and roller head adapts, and is convenient to roll end to be sleeved in inner chamber 13.In top wire hole 12, have internal thread 14, jackscrew 2 is contained on top wire hole 12.

The structure of jackscrew 2 comprises jackscrew cap 21, jackscrew bar 22 and jackscrew head 23, and jackscrew cap 21 and jackscrew head 23 lay respectively at jackscrew bar 22 two ends, on jackscrew bar 22 outer walls, has external screw thread 24.External screw thread 24 and internal thread 14 are used in conjunction with.The jackscrew that jackscrew 2 is M30, makes it have enough stationkeeping abilities.The height of jackscrew cap 21 is 22mm, and the length of jackscrew bar 22 is 55mm, and the whole height of jackscrew 2 is 80mm.

Consider that roll is to utilize shaped profile turning cutter turning, so ∮ 495 roll fixtures 1 need to bear large torsional forces, by claw plane 11 and claw, coordinate, transmit large torsion to roll, meet the processing needs of pass.According to the demand of Roller Machining, for rolling ∮ 495 rolls in high line, ∮ 495 roll fixture 1 parameters are specifically as shown in table 1.
