[0002] Abrasive belt machines can be divided into several categories, such as desktop abrasive belt machines, vertical abrasive belt machines, hand-push abrasive belt machines, and dust removal abrasive belt machines. Abrasive belt machines are a working instrument, including abrasive belts, abrasive belt housings for accommodating the abrasive belts, motors, motor housings for accommodating the motors, handles, driving wheels, driven wheels, and a transmission device connecting the motors and driving wheels. Due to the continuous development of technologies such as abrasive belt machines, the role of abrasive belt machine polishing in the metal processing industry has become irreplaceable. With advanced abrasive belt polishing equipment, metal processing tasks such as surface polishing, circular polishing, finishing polishing and grinding, radius polishing, chamfering, and deburring can be successfully completed.

[0003] Patent No. CN201220590290.6 discloses a belt sander, which belongs to the field of operation technology and solves the problem that the existing belt sanders are difficult to be suitable for processing large workpieces and special-shaped workpieces. The belt sander comprises a frame and an annular belt. At least three belt pulleys capable of tensioning the belt are arranged on the inner side of the belt. All the belt pulleys are positioned on the frame. The frame has an avoidance space corresponding to the inner side of the belt. A motor is fixed on the frame. The motor shaft is connected to one of the belt pulleys. In a certain space, only the grinding section of the belt passes through the belt sander. Therefore, the workpiece can flexibly rotate around the grinding section of the belt sander. Thus, the belt sander can grind large workpieces as well as special-shaped workpieces such as frame-shaped and annular workpieces. The belt sander has multiple structures capable of tensioning the belt. Therefore, the belt sander has the advantages of convenient adjustment and fast belt replacement. The belt sander can also adjust the balance between the belt pulleys. Therefore, the belt sander has the advantage of stable belt operation. However, the device has the following problems: first, the device cannot fix the workpiece when grinding a three-dimensional workpiece. The workpiece needs to be manually pressed, which is not safe. Secondly, the device cannot grind two different forms of workpieces at the same time. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] (1) In the utility model, when processing a three-dimensional workpiece, the workpiece can be fixed in the workpiece expansion box for grinding through the workpiece expansion box, and there is no need for manual holding of the fixed three-dimensional workpiece for grinding. When the three-dimensional workpiece needs to be processed, the workpiece is placed in the frame, and then the cylinder starts to work, pushing the piston rod into the frame to clamp the three-dimensional workpiece inside the frame. At this time, the part of the clamped three-dimensional workpiece that needs to be ground protrudes from the frame and contacts with the sanding belt, which can ensure the stability of the three-dimensional workpiece during grinding. There is no need for manual holding of the three-dimensional workpiece, which reduces labor and improves safety.

When the three-dimensional workpiece is clamped by the cylinder for grinding in the workpiece expansion box, the hand-held grinding area can grind the hand-held sheet-like workpiece. The sanding belt in the hand-held grinding area rotates with the rotation of the sun gear grinding head. The sanding belt rotates continuously, and the position of the hand-held grinding area remains unchanged. The sheet-like workpiece contacts different sanding belts, so the grinding accuracy is higher and the service life of the sanding belt is longer. The two-pronged approach increases work efficiency.

[0016] In summary, the device has the advantages of improved safety, increased stability, and increased work efficiency, and is particularly suitable for the field of belt sanding machine technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Furthermore, the outer sides of the sun gear grinding head 4721 and the adjusting wheel 4731 are both provided with a sanding belt 46, and the sanding belt 46 will rotate along with the rotation of the sanding belt 45, and at the same time, the sun gear grinding head 4721 and the adjusting wheel 4731 will be driven to rotate simultaneously, so that the sanding belt 446 is rotated back and forth to grind the workpiece, and the upper side of the front end of the sun gear grinding head 4721 is provided with a hand-held grinding area 6, when the three-dimensional workpiece is clamped by the cylinder 52 for grinding in the workpiece expansion box 5, the hand-held grinding area 6 can grind the hand-held sheet-like workpiece, thereby taking a two-pronged approach to increase work efficiency.

[0029] Furthermore, a component placement frame 51 is provided on the outside of the workpiece expansion box 5, and cylinders 52 are provided on the outside of the left and right ends of the component placement frame 51. A piston rod is provided at the left center of the cylinder 52, and a pressure block 521 is fixedly connected to the left side of the piston rod. The cylinder 52 is symmetrically placed on the left and right sides. When a three-dimensional workpiece needs to be processed, the workpiece is placed in the component placement frame 51, and then the cylinder 52 starts to work and pushes the piston rod into the component placement frame 51 to clamp the three-dimensional workpiece inside the component placement frame 51.

At the same time, the transverse folded silicone 53 can provide friction on the upper and lower ends of the processed parts when they are placed, thereby increasing stability during grinding.

[0031] Working process: First, when a three-dimensional workpiece to be processed is placed in the workpiece frame 51, the cylinder 52 starts to work, pushing the piston rod into the workpiece frame 51 to clamp the three-dimensional workpiece inside the workpiece frame 51. At this time, the part of the clamped three-dimensional workpiece that needs to be ground protrudes out of the workpiece frame 51 and contacts the abrasive belt 46 to ensure the stability of the grinding of the three-dimensional workpiece.

When the required three-dimensional processed parts are of different sizes, the internal space of the opposing frame 51 can be expanded by using the horizontal folding silicone 53 and the vertical folding silicone 531. At the same time, the horizontal folding silicone 53 can provide friction at the upper and lower ends of the processed parts when they are placed, thereby increasing stability during grinding.
