Abstract

A cutting type concrete surface repairing device comprises a motor and a disc body, wherein sawteeth are arranged on the outer side of the disc body, a main shaft connected with the motor is arranged in the middle of the disc body, the disc body comprises a contact surface and a non-contact surface which are oppositely arranged, the main shaft is embedded into the disc body and extends to the upper part of the non-contact surface, the non-contact surface is in a curved surface shape with the thickness gradually reduced along the direction of the sawteeth from the main shaft, the contact surface is a flat surface with uniform thickness, and when the disc body rotates to cut, the contact surface is always contacted with a cut wall body; in addition, the contact surface is shaped flatly, so that the flatness of the cut surface can be ensured as much as possible under the condition that the cut surface has the requirement of flatness, and the expected effect can be achieved.

Description

Cutting type concrete surface repairing device

Technical Field

The utility model relates to a construction field especially relates to a cutting formula concrete face prosthetic devices.

Background

At present, the expansion die repairing of the concrete wall surface is usually carried out by polishing with a cutting machine, and the known cutter head structure of the cutting machine comprises saw teeth, a disc body and a main shaft. Generally, the end part of a cutting surface is thinner, the center of the cutting surface is thicker, and the thickness of the surface of a cutter disc is different when cutting operation is carried out, so that great operation difficulty is realized under the condition of leveling requirement, and the expected effect is not easy to achieve.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a cutting formula concrete face prosthetic devices to prior art not enough.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a cutting formula concrete face prosthetic devices, includes motor and dish body, the dish body outside is provided with the sawtooth, and the middle part of dish body is equipped with the main shaft of being connected with the motor, the dish body is including the contact surface and the non-contact surface that set up in opposite directions, main shaft embedding dish body extends to the top of non-contact surface, the non-contact is personally submitted the curved surface shape that autonomic axial sawtooth direction thickness reduces gradually, the contact surface is the even plano of thickness, and when the dish body rotated the cutting, the contact surface was all the time with by the contact of being cut wall body.

Preferably, the motor includes motor body and motor joint, the motor joint is cylindricly with the external screw thread, the screw hole that runs through the dish body is seted up at the center of main shaft, inserts the installation of accomplishing dish body and motor body fixedly in the screw hole through the motor joint.

Preferably, the direction of the connecting thread of the motor joint and the threaded hole on the cutter head is opposite to the direction of the motor joint driven by the motor body to rotate.

Preferably, the saw teeth, the disc body, the main shaft and the threaded hole are integrally formed.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model sets the back of the dish body, namely the non-contact surface, into a curved shape with different thickness and the thickness at the position of the saw teeth is the minimum, thereby on one hand, the strength of the whole dish body is increased, and on the other hand, the dish body can easily enter into the cut wall body when cutting is convenient; in addition, the contact surface is flattened, so that the flatness of the cut surface can be ensured as much as possible under the condition that the cut surface has the flatness requirement, and the expected effect is achieved.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the principles of the invention. In the drawings:

FIG. 1 is a top view of a tray body;

FIG. 2 is a rear view of the tray body;

FIG. 3 is a front view of the tray body;

fig. 4 is a schematic view of the connection of the motor and the disc body.

In the figure: 1. the motor comprises a main shaft, 2 parts of a non-contact surface, 3 parts of sawteeth, 4 parts of a threaded hole, 5 parts of a contact surface, 6 parts of a motor joint, 7 parts of a motor main body.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Referring to fig. 1 to 4, a cutting type concrete surface repairing device includes a motor and a tray body, a sawtooth 3 is arranged at the outer side of the tray body, a main shaft 1 connected with the motor is arranged at the middle part of the tray body, the tray body includes a contact surface 5 and a non-contact surface 2 which are oppositely arranged, the main shaft 1 is embedded into the tray body and extends to the upper part of the non-contact surface 2, the non-contact surface 2 is in a curved surface shape with gradually reduced thickness from the main shaft 1 to the sawtooth 3, the contact surface 5 is a flat surface with uniform thickness, when the tray body rotates to cut, the contact surface 5 is always contacted with a cut wall, therefore, the utility model discloses a back surface of the tray body, namely the non-contact surface 2 is set to be curved with different thickness and has the smallest thickness at the sawtooth 3 position, on one hand, the strength of the whole tray body is increased, on the other hand, the tray body can easily enter the cut wall when cutting is also facilitated; in addition, the contact surface 5 is shaped to be flat, so that the flatness of the cut surface can be ensured as much as possible under the condition that the cut surface has the flatness requirement to achieve the expected effect

The motor includes motor main part 7 and motor joint 6, and motor joint 6 is cylindricly that has the external screw thread, and threaded hole 4 that runs through the dish body is seted up at main shaft 1's center, and it is fixed to insert the installation of accomplishing dish body and motor main part 7 in the threaded hole 4 through motor joint 6 for the dish body is very convenient installation and dismantlement, is in addition the utility model discloses in, motor joint 6 and the connecting thread direction of threaded hole 4 on the blade disc are opposite with motor main part 7 driving motor connects 6 pivoted direction, therefore the higher dish body of motor speed can the interlock more firm more, have guaranteed safe in utilization, can not take place to take off the dish, collapse the condition of dish, guarantee user's personal safety.

Sawtooth 3, disk body, main shaft 1 and screw hole 4 integrated into one piece guarantee the cutting strength of disk body and sawtooth 3.

As above, while the invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
