Description
The technical field is as follows:
the utility model relates to a foundry goods is maintained and is ground equipment, especially relates to a foundry goods inner chamber is maintained and is ground machine.
Background art:
in the casting industry, after a casting is formed, the outside needs to be trimmed and ground, regular casting trimming is relatively simple, but an inner cavity exists in an irregular casting, and in the prior art, two grinding devices are often adopted for correcting the inner cavity, wherein the first grinding device is formed by a grinding head and a motor (the grinding head and the motor are in a straight line), the second grinding device is formed by a polishing sheet and the motor (the polishing sheet is parallel to the axis of the motor), and the existing grinding devices adopted for some narrow inner cavities are not easy to grind and trim, so that labor and time are wasted, and even the casting is scrapped; particularly, the distance between the polishing sheet and the motor is too short, so that the polishing sheet can not penetrate into the inner cavity to polish the side wall sometimes; the presence of the grinding head on the same axis as the motor does not facilitate the grinding operation of the side wall.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: the defects of the prior art are overcome, and the casting inner cavity finishing grinder which is simple in structure, changes the power output direction of the power shaft through the rotating device, is matched with the grinding head and the polishing sheet and grinds the narrow inner cavity is provided.
The technical scheme of the utility model is that: the casting inner cavity finishing grinder comprises a motor and a grinding sheet, wherein a transmission device is detachably arranged on a rotating shaft of the motor, and the grinding sheet is arranged on the transmission device and is perpendicular to or parallel to the axis of the motor.
Furthermore, the transmission device comprises a first transmission device for realizing that the output shaft is vertical to the power shaft of the motor and a second rotation device for realizing that the output shaft and the power shaft of the motor are in the same straight line.
Furthermore, the grinding sheet comprises a grinding head and a polishing sheet, the grinding head is connected with the motor through the first transmission device, and the polishing sheet is connected with the motor through the second rotating device.
The utility model has the advantages that:
1. the utility model discloses set up transmission on current motor, change the power take off direction of power shaft through rotating device to cooperation bistrique and buffing piece grind narrow and small inner chamber, labour saving and time saving improves work efficiency.
2. The utility model discloses the bistrique is perpendicular with the motor axis, and when the bistrique gos deep into the inner chamber and grinds, personnel handheld motor is convenient for operate to the grinding device that bistrique and motor axis are in same axis among the prior art.
3. The utility model discloses buffing piece and motor axis are in same axis, and when the buffing piece gos deep into the inner chamber and grinds, personnel handheld motor is convenient for operate to buffing piece and motor axis vertically grinding device among the prior art.
4. The utility model discloses can dismantle the connection between transmission, motor, the abrasive disc, the operation can be changed according to in service behavior to the personnel, is convenient for grind the inner chamber fast.

Figure 2 is a top view of the polishing pad and motor.
Figure 3 is a left side view of the polishing pad and motor.
Figure 4 is a front view of the grinding head and motor.
Figure 5 is a top view of the grater and motor.
Fig. 6 is a schematic structural diagram of the polishing sheet and the grinding head for finishing and grinding in the inner cavity of the casting.
The specific implementation mode is as follows:
example (b): referring to fig. 1, 2, 3, 4, 5 and 6, there are shown 1-motor, 2-first transmission, 3-second rotation device, 4-polishing plate, 5-grinding head, 6-output shaft.
The casting inner cavity finishing grinder comprises a motor 1 and a grinding sheet, wherein a transmission device is detachably arranged on a rotating shaft of the motor 1, and the grinding sheet is arranged on the transmission device and is perpendicular to or parallel to the axis of the motor.
Furthermore, the transmission device comprises a first transmission device 2 for realizing that the output shaft 6 is vertical to the power shaft of the motor 1 and a second rotating device 3 for realizing that the output shaft 6 and the power shaft of the motor 1 are in the same straight line.
Further, the grinding sheet comprises a grinding head 5 and a polishing sheet 4, the grinding head 5 is connected with the motor 1 through a first transmission device 2, and the polishing sheet 4 is connected with the motor 1 through a second rotating device 3; the first transmission device 2 and the second transmission device 3 are arranged on the motor 1 through bolts; the polishing plate 4 and the grinding head 5 are detachably fixed on the output shaft through a nut and a gasket.
The grinding head 5 is vertical to the axis of the motor 1, in particular to the axis of the grinding head 5 is vertical to the axis of the motor 1; the axes of the polishing sheet 4 and the motor 1 are in the same straight line, and specifically, the axis of the polishing sheet 4 is the same as the axis of the motor 1.
When the grinding head is used, a person grinds the side wall A of the inner cavity through the grinding machine formed by the grinding head 5 and the first transmission device 2, and grinds the upper wall B and/or the lower wall of the inner cavity through the grinding machine formed by the polishing sheet 4 and the second rotating device 3.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
