Description

Technical Field

[0001] The utility model relates to the technical field of stone grinding, in particular to a smooth surface grinding device for stone processing. Background Art

[0002] Stone is a kind of building decoration material widely used in indoor and outdoor decoration design. After the stone is mined or produced, it needs to be cut into the required shape and size, and then its surface is polished smooth. At present, fully automatic manipulators and manual handheld grinders are commonly used for polishing. Fully automatic polishing manipulators have high working efficiency and stable polishing, but the corresponding cost is relatively high.

[0003] Therefore, this application document mainly focuses on the manual hand-held grinding method. The manual hand-held grinding equipment in the prior art is generally limited in size due to the physical limitations of the workers. If it is set larger, the grinding efficiency can be increased, but heavier workers cannot use it for a long time. Even for small hand-held grinding equipment, after long-term use, workers need to keep supporting and pressing, which will cause sore arms for a long time, making it inconvenient to use. Therefore, in order to address this problem, there is a need for an improved smooth grinding equipment for stone processing. Utility Model Content

[0004] The purpose of the utility model is to provide a smooth surface grinding device for stone processing to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a smooth surface grinding equipment for stone processing, comprising a workbench, a grinding mechanism for grinding stone is arranged on one side of the workbench, the grinding mechanism comprises a column, a first rotating arm, a connecting rod, a second rotating arm, a motor, a reducer, a grinding disc, a first pulley, and a second pulley, a column is fixedly arranged on one side of the workbench, a first rotating arm is movably arranged on the upper end of the column through a bearing, a connecting rod is movably arranged on one end of the first rotating arm through a bearing, a second rotating arm is movably sleeved on the lower end of the connecting rod, a motor is fixedly arranged on one side of the surface of the second rotating arm, a reducer is arranged on the surface of the second rotating arm on one side of the motor, a grinding disc is movably arranged on the surface of the second rotating arm on one side of the reducer through a rotating shaft, a first pulley is arranged on the upper end of the reducer, and a second pulley is arranged on the upper end of the rotating shaft where the grinding disc is located.

[0006] Preferably, a transmission belt is sleeved on the outer surfaces of the first pulley and the second pulley, and the first pulley and the second pulley can be conveniently linked together through the transmission belt, so that the first pulley can conveniently drive the second pulley to rotate.

[0007] Preferably, a handle is fixedly provided on one side of the surface of the second rotating arm, and the handle can be conveniently pulled by a worker, and the first rotating arm and the second rotating arm are rotated, thereby driving the grinding head to move and grind.

However, the device needs to ensure sufficient downward pressure during grinding so that the grinding disc can fit the surface of the stone; therefore, the position of the adjusting screw of the device can be adjusted, so that the compression elastic force of the first spring becomes larger, and the downward pressure generated by the first spring is combined with the gravity of the motor so that the grinding disc can fit tightly against the outer surface of the stone to be ground; in this way, the motor can be easily lifted or the downward extrusion force can be increased for easy grinding through the adjusting screw as needed, thereby improving the use effect of the device.

[0010] Preferably, the power output shaft end of the motor is transmission connected to the power input shaft end of the reducer, and the power output shaft end of the reducer is transmission connected to the first pulley. The motor can drive the reducer to rotate, and then the reducer can drive the first pulley to rotate, and then the transmission belt can drive the second pulley and the grinding disc to rotate to perform grinding work.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model is supported by the first rotating arm, the second rotating arm and the second spring, which can ensure that the grinding head has a sufficient movable range and save the staff from the effort of supporting and lifting the grinding device.

[0020] The outer surfaces of the first pulley 9 and the second pulley 10 are sleeved with a transmission belt 11, and the first pulley 9 and the second pulley 10 can be conveniently linked together through the transmission belt 11, so that the first pulley 9 can conveniently drive the second pulley 10 to rotate;

[0021] A handle 12 is fixedly provided on one side of the surface of the second rotating arm 5, and the handle 12 can be conveniently pulled by the staff, and the first rotating arm 3 and the second rotating arm 5 rotate, thereby driving the grinding head to move and grind;

[0022] The second rotating arm 5 is fixedly provided with a protective housing 13 at the upper end of the first pulley 9 and the second pulley 10, and the protective housing 13 can prevent the transmission belt 11 from hurting people;

[0023] The upper end of the outer surface of the connecting rod 4 is provided with an adjusting screw 14 through a threaded movably screwed engagement, and the outer surface of the connecting rod 4 is sleeved with a first spring 15 between the adjusting screw 14 and the second rotating arm 5, and the lower end of the outer surface of the connecting rod 4 is fixedly provided with a limiting ring 16, and the surface of the connecting rod 4 is sleeved with a second spring 17 between the limiting ring 16 and the second rotating arm 5.
