Description
Technical Field
The utility model relates to an engineering machine tool field.
Background
Two groups of oil scraping rollers are arranged at the outlet of the stainless steel cold continuous rolling mill, and one oil scraping roller is arranged on the upper surface and the lower surface of each group of strip steel and is responsible for intercepting rolling liquid taken out by the strip steel of the rolling mill in a unit. After the oil scraping roller runs for a period of time, the roughness of the surface is reduced due to abrasion, the roller shape is deformed, the oil scraping effect is influenced, and the outer circle surface of the oil scraping roller is ground again by the upper grinding machine to recover the roughness and the roller shape.
The oil scraping roller consists of an outer layer hollow copper roller, a mandrel, a bearing and a retainer ring. Because the bearing has a certain gap, the working state of the copper roller and the mandrel is eccentric after the oil scraping roller is pressed down and contacts the steel plate, and the copper roller rotates relative to the mandrel. The surface of the oil scraping roller must be completely disassembled and machined on a lathe before being machined. But good concentric positioning and locking of the copper roll and mandrel are necessary to perform the grinding process on the grinding machine. Therefore, a clamp with the functions of aligning and locking is required to be designed to grind the oil scraping roller.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a rolling mill oil scraping roller grinding centering fixture to above-mentioned problem exactly.
The purpose of the utility model is realized like this: rolling mill oil scraping roller grinding centering fixture includes, anchor clamps body and bolt, the anchor clamps body be a circular slab, the circular slab in the middle of be provided with the through-hole, the through-hole constitute by four sections circular arcs, be two sections orthodrome from top to bottom, control and be two sections little circular arcs, the circular slab about install the bolt respectively in the middle of the both ends.
Furthermore, the thickness of the left end and the right end of the circular plate is 0.5-3mm thicker than that of the upper end and the lower end.
Furthermore, the through holes are symmetrical up and down and symmetrical left and right.
Furthermore, the center hole of the clamp corresponds to the excircle of the mandrel of the oil scraping roller of the rolling mill, and the gap is 0.5-1 mm.
Furthermore, the diameter of the outer circle of the clamp corresponds to the diameter of the inner circle of a copper roller of the oil scraping roller mandrel of the rolling mill, and the gap is 0.5-1 mm.
The utility model has the advantages that: 1. the grinding roundness, cylindricity, curve precision and roughness are ensured, 2, the grinding efficiency is improved, 3, the clamping time is shortened, 4, the aligning precision is improved, and the method is simple and easy to operate.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a front view of the present invention.
Fig. 2 is a left side view of the present invention.
Detailed Description
Before the oil scraping roller is ground, a centering fixture is used for fixing, so that the hollow copper roller and the mandrel cannot rotate relatively, and the eccentricity of the copper roller and the mandrel is adjusted and eliminated. When the fixture is adjusted, the outer circle of the fixture slightly deforms and expands to be attached to the inner circle of the copper roller, so that the hollow copper roller and the mandrel form a whole, the purpose of clamping is achieved, and the machining condition of the upper grinding machine is met.
Technical scheme
1. The clamp is made of steel, the left bolt and the right bolt are respectively used for tightly jacking the mandrel to enable the clamp to deform outwards, so that the hollow copper roller of the oil scraping roller and the mandrel do not rotate relatively, and the left bolt and the right bolt are continuously adjusted to be concentric;
2. the upper top and the lower top and the bottom of the clamp are made into thin walls, so that the clamp is slightly deformed and is tightly attached to the inner circle of the copper roller;
3. the center hole of the clamp corresponds to the excircle of the mandrel, the gap is ensured to be 0.5-1.0mm, and a small gap is kept;
4. the diameter of the outer circle of the clamp corresponds to the diameter of the inner circle of the copper roller, the gap is guaranteed to be 0.5-1.0mm, a small gap is kept, the major diameter of the clamp is 0.5mm larger than the diameter of the inner circle of the copper roller, the minor diameter of the clamp is 0.5mm smaller than the diameter of the inner circle of the copper roller, and the middle diameter of the clamp is just equal to the inner diameter of the copper roller.
5. The outer circle of the clamp is a conical surface and is used for being attached to the inner surface of the copper roller.
Before the oil scraping roller is ground, a clamp is required to be installed. The 2 anchor clamps are 1 group, and the scraper roll is respectively installed 1 about. During installation, the bolt is aligned to 2 semicircular holes in the end face of the oil scraping roller, and the bolt is conveniently screwed by an inner hexagonal wrench. And then measuring the eccentricity degree by using a depth gauge, and adjusting the front and rear 4 bolts to enable the eccentricity value to meet the grinding requirement. And finally, clamping the cylindrical surface on a grinding machine for grinding the cylindrical surface.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
