Description

TECHNICAL FIELD

[0001] The present application relates to the field of machining equipment, in particular to a lathe for roll. BACKGROUND

[0002] After the roll is used for a period of time, the roll needs to be modified by using a roll lathe. Roll repair includes restoring the roll after being worn or having surface defects to the original design size, repairing the roll with surface defects, and processing the used roll into a smaller size roll for other stands. This process not only helps to extend the service life of the roll, but also improves production efficiency and product quality, and reduces enterprise cost.

[0003] In related technologies, the roll lathe usually clamps both ends of the roll by using a clamping mechanism, and processes the roll surface by using a cutting mechanism. However, for a long roll, a slight elastic deformation will occur in the middle of the roll during the processing due to the action of gravity, which will affect the processing precision and surface quality. CONTENT OF THE INVENTION

At the same time, this design can also reduce the possibility of debris entering the gap between the support assembly and the roll, further improving the stability and service life of the lathe.

[0020] Preferably, the support frame is detachably connected with the rack.

[0021] By adopting the technical scheme, the detachable connection between the support frame and the rack makes the support frame convenient to install and disassemble, facilitates the maintenance and replacement, and improves the flexibility and maintenance efficiency of the equipment.

The other end of the support rod 62 is fixedly connected with the mounting plate 63.

[0043] Referring to Figure 2 and Figure 3The fixed frame 61 is slidingly connected with a plug rod 7, and the plug rod 7 is horizontally arranged. The support rod 62 is provided with a plug hole 621, and when the support rod 62 is vertically arranged, the plug rod 7 is inserted into the plug hole 621, thereby fixing the support rod 62 and the fixed frame 61.

[0044] Referring to Figure 1 and Figure 2 The magnet 64 is arranged in an arc shape, and the arc shape matches the outer periphery of the roller. A gap is left between the magnet 64 and the roller.

[0048] The use principle of the present application is as follows: by adding the support assembly 4 and the cleaning assembly 6 to the roller lathe, effective support of the long roller and efficient cleaning of the scraps are realized. The first roller 41 and the second roller 43 in the support assembly 4 can provide stable support on both sides of the roller, thereby reducing the possibility of deformation in the middle part due to the action of gravity, and thereby improving the machining precision and surface quality.
