Description

Technical Field

[0001] The utility model relates to the technical field of abrasive machines, in particular to a dust suction mechanism for abrasive machines. Background Art

[0002] A grinding machine is a machine that grinds the surface of a workpiece using a grinding tool coated or embedded with abrasives. It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in workpieces.

[0003] Existing grinding machines will generate a large amount of dust during the process of grinding the workpiece surface. In order to prevent the dust from affecting the health of workshop personnel, a vacuum cleaner is used to absorb the dust generated during the operation of the grinding machine. However, since the dust generated during the operation of the grinding machine is fine and continuous, the filter of the vacuum cleaner is easily blocked by the dust when absorbing a large amount of dust, which will not only cause the suction power of the vacuum cleaner to decrease, but also easily cause the motor to be idling, which is easy to scrap the motor.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1 , Figure 3 The figure shows a dust suction mechanism for an abrasive machine, comprising a vacuum cleaner body 1, and a V-shaped tube 2 fixedly mounted on the outside of the vacuum cleaner body 1, and the end of the V-shaped tube 2 away from the vacuum cleaner body 1 is fixedly connected to the abrasive machine through a bellows, a threaded tube 3 is fixedly embedded in the lower end of the V-shaped tube 2 and is interconnected with the V-shaped tube 2, and an ash receiving tube 4 is threadedly sleeved on the outer side of the threaded tube 3; a filter assembly 5 is used for pre-filtering the gas entering the vacuum cleaner body 1, and the filter assembly 5 is fixedly mounted inside the V-shaped tube 2; a drive structure 6 is used for knocking the filter assembly 5, and the drive structure 6 is also mounted inside the V-shaped tube 2 and is located on the upper right side of the filter assembly 5.

[0023] See also Figure 4 The filter assembly 5 includes a ring-shaped fixed frame 501, and a filter cloth 503 is fixedly embedded inside the fixed frame 501. The filter cloth 503 can filter dust in the gas.

[0024] The working principle that can reduce the operating burden of the vacuum cleaner: during the operation of the grinder and the vacuum cleaner main body 1, the gas enters the vacuum cleaner main body 1 through the V-shaped tube 2. When the gas passes through the V-shaped tube 2, part of the dust carried in the gas will settle at the bend of the V-shaped tube 2 and fall into the dust collecting tube 4. Then the filter cloth 503 filters the gas, thereby reducing the dust content in the gas entering the vacuum cleaner main body 1, reducing the operating burden of the vacuum cleaner main body 1, and facilitating the normal operation of the vacuum cleaner main body 1.

[0025] Embodiment 2

[0026] See also Figure 2 , Figure 4 This embodiment further explains Example 1. The driving structure 6 includes a connecting shaft 601 that can rotate inside the V-shaped tube 2. An impeller 602 is fixedly sleeved on the outer side of the connecting shaft 601. The impeller 602 can rotate when driven by the airflow. Two symmetrically distributed metal springs 603 are fixedly embedded on the outer side of one end of the impeller 602 close to the filter component 5. A solid ball 604 is fixedly connected to the end of the metal spring 603 away from the connecting shaft 601. The metal spring 603 has elastic potential energy.

[0027] See also Figure 4 A plurality of grooves 7 equidistantly distributed around the circumference are provided on the inner wall of the fixed frame 501, and the solid ball 604 is in rotational contact with the fixed frame 501 through the plurality of grooves 7, the width of the groove 7 is greater than the diameter of the solid ball 604, and two positioning seats 605 are fixedly installed on both sides of the impeller 602 inside the V-shaped tube 2, and the connecting shaft 601 is rotationally connected to the positioning seat 605 through a bearing, and the bearing can reduce the friction between the connecting shaft 601 and the positioning seat 605.

[0028] In this embodiment: when the vacuum cleaner body 1 is in operation, the airflow inside the V-shaped tube 2 will drive the impeller 602 to rotate, and the solid ball 604 will rotate together with the impeller 602 driven by the connecting shaft 601. During the rotation, the solid ball 604 will slide in contact with the fixed frame 501 through a plurality of grooves 7 equidistantly distributed around the circumference, which can cause the fixed frame 501 and the filter cloth 503 to vibrate, thereby preventing dust from accumulating on the outside of the filter cloth 503 and reducing the gas flow entering the vacuum cleaner body 1.

[0029] Embodiment 3

[0030] See also Figure 4 This embodiment further illustrates other embodiments. A rubber ring 502 is solidly sleeved on the outer side of the fixing frame 501. The rubber ring 502 can reduce the shock of the V-shaped tube 2. The connection between the rubber ring 502 and the V-shaped tube 2 is fixed and adhered.

[0031] In this embodiment, since the fixing frame 501 is fixedly connected to the V-shaped tube 2 via the rubber ring 502 , the V-shaped tube 2 can be prevented from vibrating during the vibration of the fixing frame 501 and the filter cloth 503 .
