Description

Technical Field

[0001] The utility model relates to the technical field of burr grinding devices, in particular to a burr grinding device for metal processing. Background Art

[0002] In the process of metal processing, burrs are inevitable, and deburring and grinding the metal parts after the outer side is processed is an extremely common processing step. There are various types of metal part burr grinding devices in the prior art, including fully automatic and semi-automatic manually operated grinding devices. This application document mainly improves the semi-automatic grinding device. In the prior art, the angle of the grinding belt of such semi-automatic grinding devices is generally fixed when in use. So if the inclined surface of a part needs to be polished, since the angle of the grinding belt of the grinding device is fixed, it is only possible to tilt the part so that the inclined surface of the part can be fitted on the outer surface of the grinding belt for grinding. Once the part is tilted, subsequent clamping and fixing processes are more troublesome. Therefore, to address this problem, there is a need for an improved burr grinding device for metal processing.

The grinding mechanism includes a movable rod 3, a driving wheel 4, a rotating frame 5, a driven wheel 6, and a grinding belt 7. A movable rod 3 is movably inserted into one side of the support frame 2, and a driving wheel 4 is movably provided at one end of the movable rod 3 through a rotating shaft. A rotating frame 5 is movably provided at the end of the support frame 2 away from the driving wheel 4 through a rotating shaft. A driven wheel 6 is movably provided at the upper and lower ends of the rotating frame 5 through a rotating shaft. A grinding belt 7 is sleeved between the driving wheel 4 and the driven wheel 6. A mounting plate is fixedly provided at the lower end of the movable rod 3, and a motor 8 is fixedly provided at the upper end of the mounting plate. The output shaft end of the motor 8 is connected to the rotating shaft where the driving wheel 4 is located through a belt and a pulley.

[0019] A telescopic rod 9 is fixedly provided on the upper end of the base plate 1 on one side of the driving wheel 4. A placement table 10 is provided on the upper end of the telescopic rod 9. The placement table 10 can be used to conveniently fix the parts to be polished; so that the parts can be easily contacted with the polishing belt 7 for polishing operation;

[0020] A fixing block 11 is fixedly provided on one side of the upper end of the placing table 10, and a push rod 12 is movably inserted into the fixed block 11. A clamping vise 13 is fixedly provided on the end of the push rod 12 close to the grinding belt 7, and a part is clamped inside the clamping vise 13; the clamping vise 13 can conveniently clamp the part to be polished, and the push rod 12 can push the clamping vise 13 and the part to move in the direction close to the grinding belt 7;

[0021] The outer surface of the rotating frame 5 is fixedly provided with an arc-shaped connecting block 14, and the surface of the arc-shaped connecting block 14 is provided with an arc-shaped through groove 15. The arc-shaped connecting block 14 and the arc-shaped through groove 15 can play a role in fixing the rotation angle of the rotating frame 5;

[0022] The outer surface of the support frame 2 is provided with a locking screw 16 through a threaded engagement, and the arc-shaped connecting block 14 is sleeved on the outer surface of the locking screw 16 through the arc-shaped through groove 15. By tightening the locking screw 16 through the thread, the arc-shaped connecting block 14 can be squeezed; thereby, the arc-shaped connecting block 14 and the rotating frame 5 can be locked.

[0023] The support frame 2 is provided with a spring 17 inside, and the spring 17 can push the movable rod 3 to move away from the driven wheel 6; thereby ensuring that the driving wheel 4 and the driven wheel 6 can tighten the sanding belt 7.

[0024] Working principle: When using the device, the angle of the grinding belt 7 of the device can be adjusted as needed. When it is necessary to grind the vertical surface of the part, keep the grinding belt vertical, and then push the clamping vise 13 and the part to move toward the grinding belt 7 through the push rod 12 until the grinding belt 7 is pushed into contact with the outer surface of the part and then grinding can be carried out; and when it is necessary to grind the inclined surface of the part, rotate the rotating frame 5 so that the rotating frame 5 rotates and tilts; forming Figure 2 The state shown is shown, and then the rotation angle of the rotating frame 5 is fixed by tightening the screw 16. At this time, the inclination angle of the grinding belt 7 is parallel to the inclined surface of the part. At this time, the staff pushes the clamping vise 13 and the part to move in the direction of the grinding belt 7 by the push rod 12 again to grind the inclined surface of the part. In this way, since the rotation angle of the rotating frame 5 of the device can be adjusted as needed, the angle of the grinding belt 7 can be changed, so that different surfaces of the part can be conveniently ground and deburred.

[0025] When the device is in use, as the rotating frame 5 rotates, the spring 17 pushes the movable rod 3 to move accordingly, ensuring that the driving wheel 4 and the driven wheel 6 can tighten the sanding belt 7, ensuring the sanding effect. Whether sanding vertical or inclined surfaces, the user only needs to push the push rod horizontally, without having to hold the workpiece during sanding, which is safer.
