Abstract

The invention relates to a retention ring device for a vertical roll grinding disc. The retention ring device comprises a fixed retention ring, an adjustable retention ring, adjusting bolts and adjusting nuts, and is characterized in that the adjustable retention ring is arranged on an adjusting ring fixed through a guide ring; the adjusting ring is formed in a way that two half ring bodies obtained by processing and symmetrically dividing the whole ring are spliced; the adjustable retention ring is uniformly divided into 12 blocks in the circumferential direction which are combined and mounted; and the adjusting ring is subjected to serial processing and manufacturing according to the 5 mm difference of adjacent specification heights. According to the retention ring device, the structures of the conventional retention rings are radically changed, the retention rings do not need to be detached layer by layer by wasting time and energy when being adjusted in height, the production efficiency is improved to the greatest extent, the labor cost is reduced, the shutdown time is shortened, and the considerable economic benefits are created for enterprises. Moreover, the retention ring device is simple in structure, strong in usability, and convenient to manufacture and mount.

Description

A kind of collet device for the vertical roller grinder mill

Technical field

The invention belongs to building material industry vertical roller grinder technical field, particularly relate to a kind of collet device for the vertical roller grinder mill.

Background technology

Vertical roller grinder is widely used in the production of building material industry powder body material, because material is totally different, causes same specification Vertical Mill different at the required collet height of different factories, often needs to adjust the collet height between limber up period.The vertical roller grinder mill collet that uses at present mostly is laminated construction, needs long-time dismounting in the adjustment, uses inconvenience, has a strong impact on production efficiency.

Summary of the invention

The present invention provides a kind of collet device for the vertical roller grinder mill for solving the technical problem that exists in the known technology, and this apparatus structure is reasonable in design, processing and manufacturing easy, can regulate easily and fast the collet height.

The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of collet device for the roller type vertical mill mill, by fixing collet, can regulate collet, adjusting bolt and adjusting nut and form, be characterized in that the described collet of regulating places by on the fixing adjustable ring of guide ring;

Described adjustable ring is spliced by two hemizonids of the rear symmetry division of whole circle processing;

The described collet of regulating along the circumferential direction is divided into 12 combination installations;

Described adjustable ring carries out the seriation processing and manufacturing according to adjacent-specification discrepancy in elevation 5mm.

Advantage and good effect that the present invention has are: 1, can regulate collet and place by on the fixing adjustable ring of guide ring, and can regulate by adjustable ring and can regulate collet and cooperate with fixing collet, and reach the height of needs; 2, with in two splicing installation after the whole circle processing of adjustable ring, be convenient to be fixed in the guide ring; 3, can regulate collet and be divided into 12 at circumferencial direction and install, reduce widely manufacturing and installation difficulty; 4, adjustable ring carries out the seriation processing and manufacturing according to adjacent-specification discrepancy in elevation 5mm, makes range of choice wide in range, is conducive to regulate quickly and accurately the collet height.

In sum; the present invention has thoroughly changed traditional collet structure; need not to waste time and energy again when adjusting height and successively dismantle collet; farthest improved production efficiency and reduced cost of labor, reduced downtime; for enterprise created considerable economic benefit and the present invention simple in structure; ease for use is strong, is convenient to make and install.

The specific embodiment

For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:

See also Fig. 1 ~ Fig. 7, a kind of collet device for the roller type vertical mill mill comprises fixedly collet 1, can regulate collet 2, adjusting bolt 3 and adjusting nut 4, and the described collet 2 of regulating places by on the fixing adjustable ring 5 of guide ring 6; Adjustable ring 5 is spliced by two hemizonids of the rear symmetry division of whole circle processing; Can regulate collet 2 is combined by 12 of five equilibrium along the circumferential direction, offer 5 bolts hole for every, be connected and fixed by 5 adjusting bolts, also can along the circumferential direction be divided into more or less and offer as required different bolt hole numbers with regulating collet 2 according to the size of grinding machine specification; Adjustable ring 5 carries out the seriation processing and manufacturing according to adjacent-specification discrepancy in elevation 5mm, can select as required the adjustable ring of differing heights in the installation.

The erection sequence of said apparatus is as follows:

1, at first guide ring 6 is positioned over relevant position on the mill;

2, find the position of adjusting bolt 3 corresponding guide rings 6, make both circumference concentric, adjusting bolt 3 bottoms are fixedly welded in the guide ring 6;

3, will be welded and fixed with concentric guide ring bottom, 6 outer ring and the mill of adjusting bolt 3 circumference again;

4, as required collet height selects the adjustable ring 5 of proper height to place in the guide ring 6;

5, can regulate collet 2 and place on the adjustable ring 5, fastening adjustment nut 4 is finished the installation that can regulate collet;

6, the repetition above-mentioned steps installs other piece and can regulate collet.

Operation principle of the present invention:

See also Fig. 8 ~ Figure 10, the present invention does not need to dismantle collet, utilizes guide ring directed to adjustable ring, by the fixing basic height of collet assurance, utilizes the adjustable ring adjustment of differing heights can regulate the collet height.Its process is simple, only need unclamp the fixing adjusting nut that can regulate collet, replace as required the adjustable ring of differing heights, tighten again adjusting nut, can quick and precisely collet be adjusted to the height of wanting, thereby reach the purpose of adjusting whole roller mill mill collet desired height.All regulate by adjustable ring and the elasticity bolt of changing differing heights and can realize; thoroughly changed traditional collet structure; need not to waste time and energy again when adjusting height and successively dismantle collet; farthest improved production efficiency and reduced cost of labor, reduced downtime; for enterprise created considerable economic benefit and the present invention simple in structure; ease for use is strong, is convenient to make and install.
