Description

Technical Field

[0001] The invention belongs to the technical field of polishing and grinding, and relates to a cantilever telescopic movable polishing and grinding device. Background Art

[0002] Existing traditional grinding equipment is difficult to achieve multi-angle grinding of irregular shaped parts, difficult to process the inside of the shell, and difficult to operate in a small space; for polishing and grinding the inner wall of the shell, the existing domestic equipment usually directly connects the drive motor and the grinding work device, which is often large in size. It is often difficult to reach into the workpiece for grinding small and medium-sized shells. In addition, due to the heavy weight of the equipment, it is often fixed on the ground and cannot be moved, and the mobility of the equipment is not high. Summary of the invention

[0003] In order to overcome the current situation that existing traditional grinding equipment is difficult to perform polishing and grinding operations in a narrow space and the equipment has low mobility, the present invention provides a cantilever telescopic movable polishing and grinding equipment. Since the driving device and the grinding working device are respectively located at the two ends of the beam, the volume of the grinding working device is greatly reduced, and it can meet the multi-angle automatic polishing and grinding of the inner and outer walls of narrower shell-shaped workpieces. The equipment is equipped with walking wheels, which is convenient for flexible conversion of working positions.

[0004] The technical solution adopted by the present invention is:

[0005] A cantilever telescopic movable polishing and grinding equipment comprises a main frame, a screw lifting device, a lifting guide rail device, a translation slide rail device, a main drive motor, a crossbeam, a flexible shaft, a grinding working device, an end joint arm, an intermediate joint arm, a hollow servo turntable, a frame oblique support, a mounting base, walking wheels, and telescopic legs.

[0006] The screw lifting device is installed on the top of the main frame, the beam is installed on the translation slide device, the translation slide device is connected to the lifting guide rail device, the screw lifting device can drive the beam to rise or fall along the lifting guide rail device, and the beam can also slide left or right along the translation slide rail device. The main drive motor is installed on the right side of the beam. The grinding work device is connected to the hollow servo turntable through two articulated arms. The angles of the two articulated arms are adjustable. The rotation of the hollow servo turntable can drive the grinding work device to rotate along the center of the hollow servo turntable.

[0007] The output end of the main driving motor is connected to the grinding working device through a flexible shaft to achieve long-distance power transmission. The flexible shaft can be bent to meet the needs of angle adjustment of the joint arm. The middle of the hollow servo turntable is hollow to facilitate the flexible shaft to pass through it.

[0008] There are 4 walking wheels at the bottom of the equipment, which is convenient for flexible movement of the working position. The telescopic legs are installed under the mounting base. The telescopic legs can be extended out of the mounting base to serve as a reinforced support for the equipment to ensure the stability of the equipment during operation.

[0009] In order to further achieve the purpose of the present invention, the grinding working device can be easily replaced with abrasive units of different forms to meet different grinding process requirements.

[0010] Preferably, the two articulated arms can be equipped with servo electric control functions to further improve the automated processing capabilities of the equipment.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The beam can move left and right and up and down.

[0013] 2. The two articulated arms can be adjusted in angle to increase the reach of the grinding work device.

[0014] 3. The output end of the main driving motor is connected to the grinding working device through a flexible shaft to achieve long-distance power transmission.

[0015] 4. The grinding working device is connected to the hollow servo turntable through two articulated arms. The rotation of the hollow servo turntable drives the grinding working device to rotate along the center of the hollow servo turntable to adapt to multi-angle grinding under different working conditions.

[0016] 5. The equipment is equipped with walking wheels to facilitate flexible change of working positions. The telescopic legs are installed under the mounting base. The telescopic legs can be extended out of the mounting base to serve as a reinforced support for the equipment to enhance the stability of the equipment during the grinding process.
