Description

Positioning device for processing inner groove of workpiece

Technical Field

The utility model relates to the technical field of mechanical equipment, in particular to a positioning device for processing inner grooves of workpieces.

Background Art

The internal groove processing of the workpiece is a common operation in the manufacturing process. The groove structure is formed inside the workpiece by processing methods. Common processing methods include milling, turning, and electric spark processing. A Chinese patent discloses a workpiece positioning structure for mechanical equipment processing (publication number: CN213135953U). The device is provided with a second limit rod and a top plate. The top plate can slide outside the second limit rod, so that the staff can adjust the front and rear position of the workpiece on the positioning structure conveniently, thereby shortening the time for the staff to position the front and rear position of the workpiece and improving work efficiency. However, the device still has the following problems when used:

Although an air pump is provided in the above-mentioned device and air holes are opened in the top plate so that negative pressure is generated in the air holes when the air pump is started, thereby producing an adsorption effect on the workpiece, the number and positions of the air holes on the top of the top plate cannot be adjusted. Therefore, when a smaller workpiece is placed above the top plate, there may be excess air holes exposed and not in contact with the workpiece. If the workpiece is grooved at this time, debris generated by grinding may enter the air holes, and the debris may enter the air pump or be discharged into the external environment, causing pollution.

Utility Model Content

The technical problems to be solved by the utility model are as follows:

When a smaller workpiece is placed on the top plate, there may be extra pores exposed and not in contact with the workpiece.

The working principle of this utility model:

First, the workpiece to be processed is placed on the placement plate 104, and then the cylinder 102 is started. The piston end of the cylinder 102 drives the lifting plate 103 to fall. During this period, the lifting plate 103 drives the first rotating rod 201 to move, and the connecting member 105 slides in the limiting groove 202 and limits the movement state of the first rotating rod 201. When the lifting plate 103 drops to the lowest point, the pressing plate 205 just falls and presses the top of the workpiece;

Secondly, when the lifting plate 103 falls, the return spring 302 releases its elastic potential energy, pulling the second rotating rod 301 to rotate toward the storage plate 104, and the second rotating rod 301 pushes the workpiece above the storage plate 104 close to the first rotating rod 201. When the first rotating rod 201 and the second rotating rod 301 respectively clamp the two sides of the workpiece, the exhaust port 308 is connected to the air pump. When the air pump is working, a negative pressure is created inside the second rotating rod 301, so that the debris generated during the processing of the workpiece enters from the dust collecting port 305, and then the debris is intercepted by the dustproof net 207 and stays inside the dust box 306. After the workpiece is processed, the dust box 306 is pulled out and the internal debris is cleaned.

All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
