Description
Technical Field
The utility model relates to the technical field of cutter quantity, in particular to a composite roll finishing cutter.
Background
The surface roughness in the cavity of the front shell (annular cavity) is required to be controlled at Ra1.0, a rolling process is necessary to ensure the roughness, the annular cavity of the front shell belongs to a deep and narrow cavity, scrap iron generated during processing is difficult to discharge, and even if the scrap iron is cleaned by compressed air, the scrap iron cannot be cleaned.
The inventors found in the course of implementing the present utility model that:
In the roll finishing process, a traditional precious stone rolling head is generally adopted for processing, and due to the fact that the precious stone rolling head is high in hardness and brittleness, scrap iron can cause the precious stone to crack, the precious stone rolling head is damaged, the price of the precious stone rolling head is more than thousands of yuan, the cost of a cutter is too high, the production efficiency is low, and enterprises are difficult to bear.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model provides a composite roll finishing cutter, which can avoid the roll head from cracking caused by scrap iron, realize simultaneous roll finishing of the inner wall and the outer wall of an annular cavity by one cutter, save working procedures and reduce cutter cost.
For this purpose, the technical scheme of the utility model is as follows: the utility model provides a compound roll finish cutter, includes the cutter arbor, and the one end of cutter arbor is handle of a knife end, and the other end is the cutting end, is equipped with the roll finish cutter on the cutting end, its characterized in that:
Through holes which are arranged in parallel and at intervals are arranged at the same height position on two sides of the end part of the cutting end, one end of each through hole is of a diameter-reducing structure, the other end of each through hole is provided with an internal thread, the diameter-reducing structures of the two through holes are reversely arranged,
The steel ball, the spring and the screw rod are sequentially arranged from one side of the reduced diameter to the other side of the reduced diameter, the screw rod is connected in the through hole through threads, and under the action of the spring, the steel ball part extends out of the reduced diameter end face to form the polishing cutter.
The technical scheme is further improved as follows: the steel ball is made of hard alloy materials.
The technical scheme is further improved as follows: the inner end of the screw rod is of a conical structure, and an inner hexagonal groove is formed in the outer end face of the screw rod.
The technical scheme is further improved as follows: the diameter-reducing structure of the through hole is that the diameter of the inner-outer extension hole gradually decreases to be attached to the spherical surface of the steel ball.
The beneficial effects are that: according to the utility model, the elastic hard steel balls are arranged on the two sides of the cutting end of the cutter bar, so that the inner wall and the outer wall of the annular cavity of the front shell can be simultaneously subjected to rolling polishing, the working procedures are saved, and buffering and scrap iron cracking are avoided through spring transition, so that the service life of the cutter is prolonged, the efficiency is improved, and the cost is reduced.
Drawings
Fig. 1 is a structural diagram of the present utility model.
Fig. 2 is a view from A-A in fig. 1.
The figure shows: 1. a knife handle end; 2. a cutting end; 3. a steel ball; 4. a spring; 5. and a screw rod.
Detailed Description
The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings, but the embodiment should not be construed as limiting the present utility model.
The utility model is shown in fig. 1 and 2:
The composite rolling cutter comprises a cutter bar, one end of the cutter bar is a cutter handle end 1, the other end is a cutting end 2, a rolling cutter is arranged on the cutting end, the rolling cutter has the specific structure that,
Through holes which are arranged in parallel and at intervals are arranged at the same height position on two sides of the end part of the cutting end, one end of each through hole is of a diameter-reducing structure, the other end of each through hole is provided with an internal thread, the diameter-reducing structures of the two through holes are reversely arranged,
The steel ball 3, the spring 4 and the screw rod 5 are sequentially arranged from one side of the reduced diameter to the other side of the reduced diameter, the screw rod is connected in the through hole through threads, and under the action of the spring, the steel ball part extends out of the reduced diameter end face to form the polishing cutter.
The steel ball is made of hard alloy materials, such as YG3x/K01/1420-92.5, YG6 x/K15/1800-92.0, GE3/M40/2600-90.0 and the like, and compared with a precious stone rolling head, the steel ball is low in price and can greatly reduce the cost of a cutter.
In the embodiment, the inner end of the screw rod is of a conical structure, and the outer end face of the screw rod is provided with an inner hexagonal groove. The inner end adopts the toper structure, avoids the spring to block simultaneously to increase the length of spring, and the outer end sets up interior hexagonal recess, uses the instrument application of force when being convenient for dismouting.
In the embodiment, the diameter-reducing structure of the through hole is formed by gradually reducing the diameter of the inner-outer extension hole and attaching the diameter-reducing structure to the spherical surface of the steel ball, so that the friction force and the movement of the steel ball can be reduced and the service life of the steel ball can be prolonged when the structure is used.
Where not described in detail in this specification, techniques well known in the art.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
