Problems solved by technology

[0002] Hardware often refers to various parts and accessories used in daily life. Square tube is a kind of hardware. When some square tubes are processed, the surface needs to be punched for convenient connection or positioning installation. After the surface of the tube is drilled, in order to ensure the accuracy of its connection or positioning and installation, the inner hole will be polished and trimmed. The existing grinding equipment for the inner hole of the square tube can only grind the hole diameter of a single specification. The scope of application At the same time, when grinding the inner hole of the square tube, the inner hole cannot be ground and positioned. The grinding degree of the inner hole of the square tube is different, which will affect the smoothness of the inner hole surface. When grinding the surface of the inner hole of the air duct, Grinding impurities will adhere to the surface of the inner hole, which is not easy to clean and affects the use of the inner hole

Embodiment 1

[0026] see Figure 1-5 , a device for grinding holes through the inner holes of square tube hardware, including a bracket 1, the surface of the bracket 1 is fixedly connected with a threaded ring frame 2, which is used to drive the thread engagement of the screw rod 3, and is used to drive the movement of the screw rod 3. The internal thread of ring frame 2 is connected with driving screw 3, which is used to drive transmission shaft 4 to move. The end of driving screw 3 away from threaded ring frame 2 is coaxially provided with transmission shaft 4. Transmission shaft 4 is composed of two parts, one of which is Located inside the adjustment mechanism 5, it is used to drive the screw and the bearing ring 6 to rotate. It includes an adjustment mechanism 5, which is used to adjust the positions of the grinding cylinder 53 and the positioning wheel 54. The adjustment mechanism 5 corresponds to the position of the screw on the surface of the transmission shaft 4 .

Abstract

The invention provides a perforated square tube hardware inner hole polishing device, and relates to the technical field of hardware. The perforated square tube hardware inner hole polishing device comprises a support and a workpiece. The surface of the support is fixedly connected with a threaded ring frame, the interior of the threaded ring frame is in threaded connection with a driving lead screw, and the end, away from the threaded ring frame, of the driving lead screw is coaxially provided with a transmission shaft. According to the perforated square tube hardware inner hole polishing device, the transmission shaft is used in cooperation with a groove disc, a groove rail is used in cooperation with a sliding block on the surface of a sliding plate, the position of a grinding barrel can be adjusted, the sliding plate is used in cooperation with positioning wheels and the grinding barrel, and by means of point contact between the positioning wheels and the inner surface of a workpiece, the grinding face of the grinding barrel and the contact face of the inner surface of the workpiece form a straight line. Therefore, the position of the polishing barrel can be positioned, the polishing barrel drives the surface to keep a horizontal contact state with the surface of an inner hole, and the polishing effect of the inner hole of a square tube can be effectively improved.
