Description

Technical Field

[0001] This utility model belongs to the field of motor rotor grinding technology, specifically relating to a waste chip collection device for motor rotor grinding. Background Technology

[0002] Motor rotor grinding refers to the process of surface treatment of the rotor, the part of the motor that is responsible for rotation. Grinding can improve the overall performance and operating efficiency of the motor, and reduce noise and vibration. However, this process may generate metal shavings or other particulate matter. Therefore, a special shavings collection device for motor rotor grinding is needed to ensure the safety and cleanliness of the working environment.

[0003] Existing motor rotor grinding waste collection devices typically collect waste only by setting up negative pressure suction ports in the grinding area. However, in practical applications, this method, which relies solely on negative pressure suction, has some problems. It is difficult to completely collect all waste, and some waste may splash due to airflow disturbances. These problems not only affect collection efficiency but also reduce the efficiency of waste collection and the overall stability of the system. Utility Model Content

[0004] In view of this, the present invention provides a waste chip collection device for grinding motor rotors. Through the negative pressure collection component, it can ensure that the waste chips after grinding can be collected in a designated place, effectively suppressing waste chip splashing, and achieving efficient collection of waste chips and stable system operation.

[0005] To solve the above-mentioned technical problems, this utility model provides a waste chip collection device for grinding motor rotors, including a grinding machine and a shielding mechanism at its upper end. A negative pressure collection component is also provided between the shielding mechanism and the grinding machine. The negative pressure collection component includes multiple upper pipes disposed within the shielding mechanism, each upper pipe having multiple first nozzles. Multiple lower pipes are disposed within the collection hopper of the grinding machine, each lower pipe having multiple second nozzles. A filter box is placed within the collection hopper of the grinding machine, located above the multiple lower pipes. An air supply component is provided at one end of the grinding machine, connected to the air inlet and outlet of the lower pipes respectively. Thus, through the negative pressure collection component, the waste chips after grinding can be concentrated and collected in a designated location, effectively suppressing waste chip splashing and achieving efficient waste chip collection and stable system operation.

[0006] The air supply component includes an air pump, which is located at one end of the grinder. Both the inlet and outlet ends of the air pump are equipped with split pipes. The inlet end of the upper pipe is connected to the split pipe at the outlet end of the air pump, and the outlet end of the lower pipe is connected to the split pipe at the inlet end of the air pump, thus serving the functions of air supply and negative pressure.

[0007] It also includes a cleaning component, which includes a scraper that is slidably connected inside the filter box. The lower end of the scraper abuts against the filter surface inside the filter box, which can move the debris on the filter surface of the filter box.

[0008] The cleaning assembly also includes lead screws that are symmetrically rotatably connected to both ends of the filter box cavity. The two ends of the scraper are respectively threaded to the corresponding lead screws, which provides a driving source for the scraper.

[0009] The cleaning assembly also includes motors symmetrically arranged at both ends of one side of the filter box. The output shafts of the motors are fixedly connected to the adjacent lead screws on the same side, thus providing a drive source for the lead screws.

[0010] The shielding mechanism includes guide rods located at the four corners of the upper end of the grinder, and protective covers are slidably connected between the four guide rods, thus achieving shielding and sealing of the grinding area.

[0011] The shielding mechanism also includes electric push rods located at both ends of the grinder. The telescopic ends of the electric push rods are fixedly connected to the bottom of the protective cover, thus providing a driving source for the protective cover.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. When the air pump in the air supply unit starts, its outlet end delivers high-pressure gas to multiple upper pipes through the split pipe. This causes the first nozzle on the upper pipe to blow air downwards to suppress the splashing of waste chips. Meanwhile, the split pipe at the air pump's inlet end connects to the outlet end of the lower pipe to create negative pressure, causing the second nozzle on the lower pipe to draw air upwards. Under the combined action of blowing and drawing, the waste chips generated during grinding are guided by the airflow into the filter box below for preliminary filtration. The filtered air then returns to the air pump through the lower pipe to form a circulation, ensuring that the waste chips after grinding can be collected in a designated area.

[0014] 2. When the filter surface inside the filter box is gradually clogged with waste debris, the motor drives the lead screw to rotate, which drives the scraper connected to it to slide along the inner wall of the filter box, pushing the retained waste debris to the edge of the filter surface for cleaning, thereby maintaining filtration efficiency and ultimately achieving efficient collection of waste debris and stable system operation.

[0015] 3. When the grinder is grinding the motor rotor, first start the electric push rod. The telescopic end moves down to drive the protective cover down along the guide rod to the top of the grinding area, forming a sealed space to prevent waste chips from scattering.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a waste chip collection device for grinding motor rotors, such as... Figure 1-4 As shown: The system includes a grinder 100 and a shielding mechanism located at its upper end. A negative pressure collection assembly is also provided between the shielding mechanism and the grinder 100. The negative pressure collection assembly includes multiple upper pipes 200 disposed within the shielding mechanism. Each upper pipe 200 is equipped with multiple first nozzles 201, the air outlets of which are all inclined towards the grinding area to ensure that the grinding debris can be directly blown down, effectively suppressing debris splashing. The collection hopper of the grinder 100 is equipped with multiple lower pipes 202, each lower pipe 202 being equipped with multiple second nozzles 203. The collection hopper of the grinder 100 contains... The machine has a filter box 204 with multiple evenly distributed filter holes at its bottom. The filter box 204 is located above multiple lower pipes 202. One end of the grinder 100 is equipped with an air supply component, which is connected to the air inlet and air outlet of the lower pipes 202. The air supply component includes an air pump 205, which is located at one end of the grinder 100. Both the air inlet and outlet of the air pump 205 are equipped with a split pipe. The air inlet of the upper pipe 200 is connected to the split pipe at the air outlet of the air pump 205, and the air outlet of the lower pipe 202 is connected to the split pipe at the air inlet of the air pump 205.

[0023] When the air pump 205 in the air supply unit is started, its outlet end delivers high-pressure gas to multiple upper pipes 200 through a split pipe. This causes the first nozzle 201 on the upper pipe to blow air downwards to suppress the splashing of waste chips. Meanwhile, the split pipe at the air pump inlet end is connected to the outlet end of the lower pipe 202 to create a negative pressure, causing the second nozzle 203 on the lower pipe to draw air upwards. Under the combined action of blowing and drawing, the waste chips generated by grinding are guided by the airflow into the filter box 204 below for preliminary filtration. The filtered air returns to the air pump 205 through the lower pipe 202 to form a cycle, ensuring that the waste chips after grinding can be collected in a designated place.

[0024] like Figure 2-4 As shown, the system also includes a cleaning assembly, which includes a scraper 300 slidably connected inside the filter box 204. The inner cavity of the filter box 204 has two concave ends, and the upper ends of the concave ends are provided with grooves to provide sliding support for the scraper 300, preventing debris from entering and affecting its sliding. The lower end of the scraper 300 abuts against the filter surface of the inner cavity of the filter box 204. The cleaning assembly also includes lead screws 301 symmetrically rotatably connected to both ends of the inner cavity of the filter box 204. The two ends of the scraper 300 are respectively threaded to the corresponding lead screws 301. The cleaning assembly also includes motors 302 symmetrically arranged at both ends of one side of the filter box 204. The output shafts of the motors 302 are respectively fixedly connected to the adjacent lead screws 301 on the same side.

[0025] Motor 302 drives lead screw 301 to rotate, which in turn drives scraper 300, which is threaded to it, to slide along the inner wall of the filter box, pushing the retained waste debris to the edge of the filter surface for cleaning, thereby maintaining filtration efficiency and ultimately achieving efficient collection of waste debris and stable system operation.

[0026] like Figure 1-3 As shown, the shielding mechanism includes guide rods 400 located at the four corners of the upper end of the grinder 100, and a protective cover 401 is slidably connected between the four guide rods 400. The shielding mechanism also includes electric push rods 402 located at both ends of the grinder 100, and the telescopic ends of the electric push rods 402 are fixedly connected to the bottom of the protective cover 401.

[0027] When the grinder 100 is grinding the motor rotor, it first starts the electric push rod 402, and the extension end moves down to drive the protective cover 401 down along the guide rod 400 to the top of the grinding area, forming a sealed space to prevent waste chips from scattering.

[0028] The working principle of the waste chip collection device for grinding motor rotors provided by this utility model is as follows: When the grinder 100 grinds the motor rotor, it first starts the electric push rod 402, and the telescopic end moves down to drive the protective cover 401 down along the guide rod 400 to above the grinding area, forming a sealed space to prevent waste chips from scattering. At the same time, the air pump 205 in the air supply component starts, and its air outlet delivers high-pressure gas to multiple upper pipes 200 through the diverter pipe. This causes the first nozzle 201 on the upper pipe to blow air downwards to suppress waste chip splashing. Meanwhile, the diverter pipe at the air pump inlet is connected to the air outlet of the lower pipe 202 to form a negative pressure, causing the waste chips on the lower pipe to be collected. The second nozzle 203 draws air upwards. Under the combined action of blowing and suction, the waste generated by grinding is guided by the airflow into the filter box 204 below for preliminary filtration. The filtered air returns to the air pump 205 through the lower pipe 202 to form a circulation, ensuring that the waste generated by grinding can be collected in a designated place. When the filter surface in the filter box 204 is gradually blocked by waste, the motor 302 drives the lead screw 301 to rotate, which drives the scraper 300 connected to it to slide along the inner wall of the filter box, pushing the retained waste to the edge of the filter surface for cleaning, thereby continuously maintaining the filtration efficiency and ultimately achieving efficient collection of waste and stable operation of the system.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
