Description

Technical field:

[0002] The invention relates to a polishing and grinding technology. Background technology:

[0004] Existing workpieces, such as stainless steel handles for cookers, need to be surface polished after forming. The existing technology is to put several stainless steel handles into a powered rotating cylinder filled with abrasives of a vibration grinder, and use the rotation of the cylinder to drive the abrasives and the stainless steel handles to move relative to each other to perform surface polishing. This polishing process not only saves the labor cost of manual polishing, but also has less pollution. However, since the stainless steel handles are freely placed in the cylinder, it is inevitable that the stainless steel handles will collide with each other, and the mutual collision is likely to cause damage to the surface of the stainless steel handles. Summary of the invention:

[0006] The object of the present invention is to provide a vibration grinding method and device which can effectively prevent workpieces to be polished from touching each other and ensure the polishing quality.

[0007] The vibration grinding method of the present invention is implemented as follows: a rotating frame driven by power or freely rotating is arranged above a cylinder body of a vibration grinder that is driven by power to rotate and filled with abrasives, and several connecting rods with connecting components are arranged below the rotating frame. The workpiece (such as a metal handle) is fixed on the connecting rod through the connecting component and the workpiece is extended into the abrasive in the cylinder body. The vibration grinder is working to polish the surface of the workpiece. The vibration of the cylinder body drives the abrasive to flow, and the flowing abrasive drives the workpiece to move, so that the rotating frame also rotates to achieve the polishing of the workpiece. Since the movement of the workpiece is carried out under the constraint of the rotating frame, it can only move according to the rotation trajectory of the rotating frame, thereby avoiding the mutual collision between the workpieces caused by the disordered movement of the workpieces randomly put into the cylinder body in the prior art, and avoiding the damage to the workpieces caused by the collision of the workpieces in the prior art.

[0008] Here, the rotating frame is arranged on the movable frame, and several sets of fixed frames are arranged, some of which are arranged at the cylinder body, and some of which are arranged far away from the cylinder body. The movable frame is first placed on the fixed frame far away from the cylinder body, and the workpiece is fixed on the connecting rod on the rotating frame, and then the movable frame with the workpiece is moved to the fixed frame at the cylinder body, so that the workpiece is extended into the abrasive in the cylinder body, and the vibration grinder is turned on to polish the metal handle. The workpiece is first fixed on the connecting rod outside the cylinder body, and then the movable frame with the workpiece is moved to the fixed frame at the cylinder body, which is convenient for the connection of the workpiece. At the same time, when the workpiece is connected, it will not affect the work of the vibration grinder, thereby effectively improving the use efficiency of the vibration grinder.

[0009] The fixed frame is transported by a vehicle with a lifting frame. The movable frame on the fixed frame outside the cylinder body is lifted by the lifting frame, and the movable frame is transferred and placed on the fixed frame at the cylinder body by the vehicle.

[0010] The vibration grinding device of the present invention is implemented as follows: it includes a vibration grinding machine, a rotating frame driven by power or freely rotating, which is arranged on a fixed frame next to the vibration grinding machine and located above the cylinder body of the vibration grinding machine, and a plurality of connecting rods with connecting components arranged below the rotating frame.

[0011] A movable frame is arranged on the fixed frame, and a plurality of freely rotating rollers are arranged below the movable frame. The plurality of rollers are distributed along the circumference and are all facing inward or outward. The rotating frame is a circular guide rail, and the cross section of the circular guide rail is a side-inverted U-shaped groove. The rollers are located in the side-inverted U-shaped groove of the circular guide rail. A plurality of connecting rods with connecting members are connected to the bottom of the circular guide rail through a connecting frame.

[0012] The connecting frame includes several connecting seats fixed on the circular guide rails, suspension rods connected to the connecting seats, trusses movably connected to the suspension rods, springs arranged between the trusses and the connecting seats, several circles of circular frames fixed on the trusses, and several connecting rods with connecting components fixed on the several circles of circular frames to form several layers of connecting rods distributed along the circumference.

[0013] During operation, the workpiece is fixed on the connecting rod through the connecting member, so that the workpiece is extended into the abrasive in the cylinder body, and the vibration grinder is turned on to polish the workpiece. Driven by the abrasive passing through the workpiece, the annular guide rail moves along the circumferential direction. If the power is set to drive the annular guide rail to rotate autonomously, the workpiece will also rotate autonomously, so that the workpiece moves along the circumferential direction. At the same time, under the dual action of the spring and the abrasive, the workpiece moves up and down, so that the workpiece is fully and evenly polished in all directions. In addition, due to the positioning of the connecting rod, the workpieces are prevented from colliding with each other and being damaged during the polishing process.

[0014] Here, there are several sets of vibration grinders with fixed frames, several sets of separately set fixed frames, several sets of movable frames with rotating frames, a car is provided, a suspension rod driven up and down by power is provided on the car, a fastening piece is provided at the lower end of the suspension rod, and a fastening connecting piece is provided on the movable frame corresponding to the fastening piece at the lower end of the suspension rod.

[0015] When working, first place the movable frame on a separately set fixed frame, then connect the workpiece to the connecting rod, then connect the suspension rod to the movable frame through the buckle parts and the buckle connecting parts, and lift the movable frame from the separately set fixed frame, and transport the movable frame to the top of the cylinder body of the vibration grinder by the vehicle, and place the movable frame on the fixed frame next to the cylinder body so that the workpiece is immersed in the abrasive in the cylinder body, and start the vibration grinder to polish and grind the workpiece. During the operation of the vibration grinder, the movable frame can be placed on a separately set fixed frame, and the workpiece can be connected to the connecting rod. In this way, the operation of the vibration grinder will not be affected during the connection of the workpiece. After the vibration grinder completes the polishing and grinding of the workpiece, the movable frame connected to the workpiece to be polished can be promptly replaced with the movable frame that has completed the polishing and grinding of the workpiece, thereby effectively improving the work efficiency and the use efficiency of the vibration grinder.

[0016] Compared with the prior art, the present invention has the advantages of being able to effectively avoid workpieces from touching each other and ensuring polishing quality. Description of the drawings:
