Description
Technical Field
The utility model belongs to the technical field of the polishing processing technique and specifically relates to a dark narrow circular arc groove burnishing device is related to.
Background
Some parts have the dark narrow circular arc groove cavity of fretwork form in machining, and dark narrow cavity cutter can take place the cutter relieving phenomenon when milling process, and the machined surface can produce great sword line, and the roughness is big. When the structural member is applied to a flight balancing mechanism, the knife lines can generate fluid disturbance to influence the flight attitude and the flight track, so that the surface must be ground and polished. The structure of the deep and narrow arc groove is limited by space, the applicable polishing equipment is less, and manual coping and polishing are generally adopted. The manual polishing has high requirements on the skill level of operators, the commonly used polishing tools or devices are not easy to operate, the surface quality consistency of the polished parts is poor, and the polishing efficiency is low.
In order to solve the above problems, it is necessary to provide a deep and narrow circular arc groove polishing apparatus to solve the problem of polishing of such parts.
SUMMERY OF THE UTILITY MODEL
In order to achieve the purpose, the utility model provides a dark narrow arc groove burnishing device.
The utility model adopts the technical scheme as follows:
a polishing device for deep and narrow arc grooves comprises a handle 1, a connecting plate 2, a body 3, a polishing medium 4 and screws 5; the end part of the handle 1 is provided with a screw rod; the body 3 is composed of a fixed handle and a polishing body, the structural shape of the polishing body is consistent with the shape of an inner arc groove to be polished, and the polishing body is in surface contact with the surface of the inner arc groove of the part during polishing; one end of the fixed handle is connected with the polishing body, and the other end of the fixed handle is fixedly connected with the screw at the end part of the handle 1 through threads; the connecting plate 2 is provided with a threaded hole, the fixing handle of the body 3 is provided with a through hole, and the polishing medium 4 is wrapped on the periphery of the body 3 and then fastened between the body 3 and the connecting plate 2 through a screw 5.
Furthermore, the polishing medium 4 can be sand paper, or a combination of linen or cotton cloth and abrasive paste, and can be replaced according to the requirements of polishing technical indexes.
The utility model has the advantages that: the utility model provides a dark narrow arc groove burnishing device has solved dark narrow arc groove inner chamber polishing technological problem, and this utility model easy operation, polishing quality uniformity is good, and is lower to operation personnel's technical ability level requirement, and polishing efficiency is high, provides the foundation to the polishing processing of similar part.
Description of the drawings:
the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1-handle, 2-connecting plate, 3-body, 4-polishing medium and 5-screw.
Detailed Description
In order to enhance the understanding of the present invention, the present invention will be described in detail with reference to the accompanying drawings.
As shown in figure 1, the polishing device for the deep and narrow arc groove comprises a handle 1, a connecting plate 2, a body 3, a polishing medium 4 and a screw 5. The handle 1 is provided with a screw at the end. The body 3 is composed of a fixed handle and a polishing body, the structural shape of the polishing body of the body 3 is consistent with the shape of an inner circular groove to be polished, and the polishing body keeps surface contact with the surface of the inner circular groove of a part during polishing. One end of the fixed handle is connected with the polishing body, and the other end of the fixed handle is fixedly connected with the screw rod at the end part of the handle 1 through threads. The polishing medium 4 is sand paper, linen, cotton cloth or grinding paste, and can be replaced according to the requirement of the polishing technical index. The connecting plate 2 is provided with a threaded hole for fastening the polishing medium 4. The fixing handle of the body 3 is provided with a through hole, and after the polishing medium 4 is wrapped on the periphery of the polishing body of the body 3, the edge of the polishing medium 4 is fastened between the body 3 and the connecting plate 2 through a screw 5.
The utility model discloses a theory of operation: the body with corresponding specification is selected according to the structural size of the cavity, so that surface contact is ensured during polishing, the acting force is uniform, and the polishing consistency is good. Meanwhile, according to the technical index requirements of the surface quality of the cavity and the actual surface condition of the cavity, a corresponding polishing medium is selected, the abrasive paper with low technical index requirements and the linen/cotton cloth with high requirements are combined with the grinding paste for use, the selected polishing medium is fastened on the periphery of the polishing body of the body, and the polishing medium has certain elasticity and can be naturally attached to the polishing body of the body under the action of external force during polishing. And (3) putting the installed polishing device into the polished arc groove cavity, holding the handle tightly for polishing in a reciprocating manner, and performing rough and fine polishing for multiple times according to actual conditions until the technical index requirements are met.
