[0002] During machining, in order to improve the surface flatness of the workpiece, it is usually necessary to use a grinding device to grind the workpiece to remove burrs on the workpiece surface. Grinding devices are divided into many types according to different degrees of freedom, including belt grinding devices, vertical grinding devices, gantry grinding devices, etc. Among them, belt grinding devices are widely used because they are relatively simple to use.

[0003] When using a belt grinder, the operator is generally required to manually hold the part close to the grinding belt for grinding. Since the operator's hand is close to the grinding belt, when grinding sheet workpieces and other thin workpieces, once an operating error occurs, it may cause injury to the operator, and the overall safety of the device is low. Therefore, a single-axis sliding sheet workpiece friction deburring device is proposed to solve the above problem. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a single-axis sliding sheet workpiece friction deburring device, including a machine table 1 for supporting the entire device, a protective shell 2 fixedly connected to the top of the machine table 1 for accommodating the grinding belt 3 to prevent it from being exposed too much, the inner wall of the protective shell 2 is rotatably connected near the bottom end to a fixed rotating shaft 8 for driving the grinding belt 3 to rotate, the inner wall of the protective shell 2 is rotatably connected near the top end to a tensioning rotating shaft 9 for guiding the grinding belt 3 to rotate, and a motor 10 is installed at the rear end of the protective shell 2 to drive the fixed rotating shaft 8 to rotate. The motor 10 is a prior art and can start working when the power is turned on. Due to the prior art, this case has not been done. More description, the front end of the output shaft of the motor 10 is fixedly connected to the rear end of the fixed rotating shaft 8. By starting the motor 10, the fixed rotating shaft 8 can be driven to rotate, and the fixed rotating shaft 8 will drive the grinding belt 3 to rotate. The outer walls of the fixed rotating shaft 8 and the tensioning rotating shaft 9 are installed with a grinding belt 3 for grinding the workpiece. The bottom end of the grinding belt 3 is relatively rough, and it can remove burrs on the surface of the workpiece when it comes into contact with the workpiece. The top end of the grinding belt 3 is made of rubber material, which has a certain elastic deformation ability and can provide greater friction when the fixed rotating shaft 8 is released. The left end of the protective shell 2 is provided with an extrusion component 7 for squeezing the grinding belt 3, and the top of the machine 1 is slidably connected with a slide plate 4 for driving the workpiece to move.

[0029] Reference Figure 2 - Figure 4The extrusion assembly 7 includes a fixing frame 71 for supporting the entire extrusion assembly 7. The right end of the fixing frame 71 is fixedly connected to the left end of the protective shell 2. The front end of the fixing frame 71 passes through and is rotatably connected to a rotating frame 72 for driving the extrusion shaft 73 to rotate. The inner wall of the rotating frame 72 is slidably connected to a slider 76 for supporting the extrusion shaft 73. The front end of the slider 76 is rotatably connected to the extrusion shaft 73 for extruding the grinding belt 3. The top of the slider 76 is fixedly connected to a protective spring 77 for protecting the workpiece. The top of the protective spring 77 is fixedly connected to the inner wall of the rotating frame 72. When the extrusion force of the grinding belt 3 on the workpiece is too large, the protective spring 77 will be forced to contract to protect the workpiece. The locking cam 77 is fixed on the locking cam 71 and the locking cam 713 is locked, so that the locking cam 713 can be locked in the unlocked state.

[0030] Reference Figure 2 - Figure 4 The top of the fixing block 712 is fixedly connected to a side plate 710 for driving the fixing block 712 to move. The right end of the side plate 710 is fixedly connected to a fixing spring 711 for pushing the side plate 710. The right end of the fixing spring 711 is fixedly connected to the inner wall of the fixing box 79. The fixing spring 711 will always push the side plate 710 to the left. The outer wall of the rotating frame 72 is fixedly connected to a torsion spring 75 for driving the rotating frame 72 to rotate and reset. The front end of the torsion spring 75 is fixedly connected to the inner wall of the fixing frame 71. The top of the slide plate 4 is provided with a positioning hole 5 for fixing the positioning plate 6. The top of the positioning hole 5 is plugged with a positioning plate 6 for fixing the workpiece. By adjusting the position of the positioning plate 6, the fixation of workpieces of different sizes can be achieved, which is more convenient when used.

[0031] Working principle: When the workpiece needs to be polished, the positioning plate 6 can be installed, and then the workpiece can be placed on the top of the slide 4. Then the slide 4 can be pushed to drive the workpiece to the bottom end of the polishing belt 3. Then the handle 74 can be rotated to drive the rotating frame 72 to rotate downward. The rotating frame 72 will drive the slider 76 and the extrusion shaft 73 to rotate downward synchronously. The extrusion shaft 73 will squeeze the polishing belt 3 so that its bottom end contacts the workpiece. Then, the slide 4 can be squeezed back and forth to polish away the burrs on the surface of the workpiece.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
