Abstract
A pin convenient for mounting and dismounting belongs to the technical field of metal standard component and is used for realizing quick dismounting of the pin. The technical scheme is characterized in that: the pin comprises a pin jacket, tapered round tables, a tension bolt and nuts, wherein the pin jacket is a cylinder, one side or two opposite sides of the pin jacket is axially provided with an elastic groove, an inner cavity of the cylinder is formed by two tapered cavities which are connected mutually, large diameter ends of the two tapered cavities are respectively arranged at two ends of the cylinder, small diameter ends of the two tapered cavities are connected mutually, number of the tapered round tables is two, conicities of the tapered round tables are respectively matched with the conicities of the two tapered cavities, a center of the tapered round table is provided with a through hole along an axial direction, the diameter of the through hole is matched with the diameter of the tension bolt. According to the pin of the utility model, the pin jacket is provided with the groove, such that the pin jacket can be provided with partial elasticity, thus the quick dismounting for the pin jacket can be realized; in addition, a structure of the tapered round table can ensure the quick dismounting for the tapered round table, and connection of the tension bolt can ensure integral intensity of the pin. The pin convenient for mounting and dismounting in the utility model has the advantages of simple manufacturing, easy dismounting and low cost.
Description
Technical field
The utility model relates to the connection bearing pin that a kind of mechanical part uses, and belongs to metal standard piece technical field.
Background technique
On steel rolling production-line, the bearing pin hinge point is numerous, and common bearing pin is a cylindrical structural, and the gap of bearing pin and equipment is less, when installing at the scene, need throw into or be pressed into special tool with sledgehammer.But in maintenance work, the dismounting bearing pin is more loaded down with trivial details usually, degree-of-difficulty factor is higher, especially through the long-term big bearing pin that uses, because its wearing and tearing, corrosion, reasons such as temperature distortion, difficulty is all compared in dismounting usually, use sledgehammer, special tool also all to be difficult to it is removed fully, both prolonged the repair time like this, be difficult for complete dismounting again, so a lot of dismountings must be taked the mode of the gas cutting old bearing pin of just dismantling, carry out new bearing pin then and change, bring very burden to service worker like this, and increased cost of production.
The model utility content
Technical problem to be solved in the utility model provides a kind of fast quick-detach that can realize bearing pin, increases the labor safety coefficient, reduces the repair time, thereby reduces the bearing pin of being convenient to mount and dismount of cost of production.
The technological scheme that solves the problems of the technologies described above is:
A kind of bearing pin of being convenient to mount and dismount, it is by the bearing pin overcoat, the taper round platform, turnbuckle, nut is formed, the bearing pin overcoat is a cylindrical body, axially have an elastic groove in a side of cylindrical body or relative both sides along cylindrical body, the inner chamber of cylindrical body is two cone-shaped cavities that are connected, the larger diameter end of two cone-shaped cavities lays respectively at the two ends of cylindrical body, the smaller diameter end of cone-shaped cavity is connected, the taper round platform is two, their tapering is complementary with the tapering of two cone-shaped cavities respectively, center at the taper round platform has through hole vertically, and the diameter of through hole and the diameter of turnbuckle are complementary, and the length of turnbuckle is greater than the length sum of two taper round platforms.
The above-mentioned bearing pin of being convenient to mount and dismount, the groove width of the elastic groove that described bearing pin puts outward are the 1/10-1/20 of bearing pin overcoat diameter, and the tapering of the cone-shaped cavity of bearing pin overcoat inner chamber body is 1:10-1:20.
Bearing pin of the present utility model puts fluting outward, makes the bearing pin overcoat have part elasticity, can realize the fast assembling-disassembling of axle sleeve, and the taper frustum cone structure is the fast assembling-disassembling that conical surface contact can guarantee the taper round platform, and turnbuckle connects can guarantee the bearing pin integral intensity.The utility model is made simple, easy accessibility, cheap, the taper round platform can use for a long time, not fragile, the replacing of bolt is very convenient quick, after certain user adopted the utility model, the step rate lifting hydraulic cylinder did not take place anyly not fall the problem of gas cutting bearing pin because of bearing pin dismounting over one year, greatly reduces maintenance labour cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Mark is as follows among the figure: bearing pin overcoat 1, taper round platform 2, turnbuckle 3, nut 4, elastic groove 5.
Embodiment
Show among the figure that the utility model is made up of bearing pin overcoat 1, taper round platform 2, turnbuckle 3, nut 4.
Bearing pin overcoat 1 is a cylindrical body, axially have an elastic groove 5 in a side of cylindrical body or relative both sides along cylindrical body, the groove width of elastic groove 5 is the 1/10-1/20 of bearing pin overcoat 1 diameter, and circumference can slightly reduce behind bearing pin overcoat 1 pressurized like this, is convenient to be driven in the pin-and-hole.
The inner chamber of the cylindrical body of bearing pin overcoat 1 is two cone-shaped cavities that are connected, and the larger diameter end of two cone-shaped cavities lays respectively at the two ends of cylindrical body, and the smaller diameter end of cone-shaped cavity is connected, and the tapering of cone-shaped cavity is 1/10-1:20.
During installation, first mount pin outer shaft sleeve 1 because bearing pin overcoat 1 flexible the retraction, is installed than being easier to, and taper round platform 2 also can arbitrarily be installed, and the rear screed reality of entering is installed, and fastening turnbuckle 3, nut 4 get final product.Can reach requirement according to the opening that the elastic groove 5 of bearing pin overcoat 1 is measured in the technical requirements at scene this moment gets final product.During dismounting the operation in contrast, during dismounting, take down turnbuckle 3 after, available suitable iron staff is done support, the taper round platform 2 of destroying other direction with hand hammer gets final product.
