[0069] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0070] See also Figure 1 , the present application embodiment provides a grinding device 100 for grinding a workpiece 200. Figure 1 and Figure 2 The grinding device 100 includes a base 10, a driving assembly 20, a rough grinding assembly 30, a fine grinding assembly 40 and a transfer assembly 50. The workpiece 200 may be a broken milling cutter, an impeller, or the like.

[0071] See also Figure 1 and Figure 2The driving assembly 20 includes a rotary driving member 21 and a screw 22. The screw 22 is rotatably connected to the base 10. The rotary driving member 21 is disposed on the base 10 and connected to the screw 22. The rotary driving member 21 is used to drive the screw 22 to rotate. The rough grinding assembly 30 and the fine grinding assembly 40 are arranged at intervals along the extension direction of the screw 22. The rough grinding assembly 30 includes a first sliding member 31 and a rough grinding member 32 connected thereto. The fine grinding assembly 40 includes a second sliding member 41 and a fine grinding member 42 connected thereto. The first sliding member 31 and the second sliding member 41 are arranged at intervals and are respectively threadedly connected to the screw 22. The first sliding member 31 and the second sliding member 41 move toward or away from each other under the drive of the screw 22 to adjust the rough grinding member 32 and the fine grinding member 42 to a preset spacing, and the grinding position of the rough grinding member 32 is higher than the grinding position of the fine grinding member 42. The transfer assembly 50 is disposed adjacent to the base 10, and is used to clamp the workpiece 200 and drive the workpiece 200 to move in a direction perpendicular to the movement direction of the first sliding member 31, so that the rough grinding member 32 and the fine grinding member 42 sequentially grind the preset area of ​​the workpiece 200. For example, the transfer assembly 50 may be a machine spindle, and the preset area of ​​the workpiece 200 may be a position to be processed of the workpiece 200, such as a broken position of a milling cutter.

[0072] The above-mentioned grinding device 100 drives the first sliding member 31 and the second sliding member 41 to move toward each other through the screw rod 22, and can adjust the spacing between the coarse grinding member 32 and the fine grinding member 42 to a preset spacing, so that the coarse grinding member 32 and the fine grinding member 42 respectively abut against the opposite sides of the workpiece 200 during grinding, so as to respectively support the two sides of the workpiece 200, avoid the workpiece 200 from being deformed due to unidirectional force during grinding, and improve the grinding accuracy; because the grinding position of the coarse grinding member 32 is higher than the grinding position of the fine grinding member 42, the clamped workpiece 200 is driven to move in a direction perpendicular to the movement direction of the first sliding member 31 through the transfer assembly 50, so that the coarse grinding member 32 and the fine grinding member 42 can grind the preset area of ​​the workpiece 200 in turn, and quickly complete the coarse and fine grinding operations on the workpiece 200, without the need for manual operation to perform coarse and fine grinding on the workpiece 200 one by one, thereby improving the grinding efficiency.

[0073] See also Figure 2 In some embodiments, the base 10 includes a placement member 11, a slide rail 12, and a cover plate 13. The placement member 11 is rotatably connected to the screw rod 22 and is provided with a placement groove 111 and a receiving groove 112 in sequence along the extension direction of the screw rod 22. The placement groove 111 and the receiving groove 112 respectively receive the rotary drive member 21 and the screw rod 22. The slide rail 12 is provided on the side of the placement member 11 facing the transfer assembly 50 and is slidably connected to the first sliding member 31 and the second sliding member 41 respectively. The slide rail 12 is used to guide the first sliding member 31 and the second sliding member 41. The cover plate 13 is covered in the placement groove 111 and is detachably connected to the placement member 11. The cover plate 13 is used to cover the placement groove 111.

[0074] In this way, the slide rail 12 is slidably connected with the first slide member 31 and the second slide member 41, respectively, so that the slide rail 12 can guide the first slide member 31 and the second slide member 41, respectively, so that the rough grinding assembly 30 and the fine grinding assembly 40 slide in the extension direction of the slide rail 12, thereby avoiding the movement direction of the rough grinding assembly 30 and the fine grinding assembly 40 from being offset, thereby improving the sliding stability of the rough grinding assembly 30 and the fine grinding assembly 40. In addition, by arranging the cover plate 13 to cover the placement groove 111, the cover plate 13 can cover the placement groove 111, thereby preventing the debris generated when the workpiece 200 is polished from splashing into the rotating drive member 21 and interfering with the normal operation of the rotating drive member 21, thereby improving the driving stability of the rotating drive member 21.

[0075] See also Figure 1 and Figure 3 In some embodiments, the rough grinding member 32 and the fine grinding member 42 each include a support portion 321, a grinding portion 322, a grinding drive portion 323 and a belt 324. The support portion 321 is disposed on the side of the first sliding member 31 or the second sliding member 41 away from the placement member 11, the grinding portion 322 is rotatably connected to the support portion 321 and is used to grind the workpiece 200, the grinding drive portion 323 is spaced apart from the support portion 321 and is disposed on the first sliding member 31 or the second sliding member 41 and is connected to the grinding portion 322 through the belt 324, and the grinding drive portion 323 is used to drive the grinding portion 322 to rotate through the belt 324. Among them, the grinding portion 322 of the rough grinding member 32, the grinding portion 322 of the fine grinding member 42, and the base 10 are sequentially arranged along a direction perpendicular to the movement direction of the first sliding member 31.

[0076] Since the grinding device 100 provided in the embodiment of the present application is applied in a machine, the internal mechanical structure of the machine is complex and the installation space in the vertical direction is small. Thus, by arranging the grinding drive part 323 and the support part 321 at intervals on the corresponding sliding parts, the space occupancy rate of the rough grinding component 30 and the fine grinding component 40 in the vertical direction can be reduced, and the grinding drive part 323 is prevented from being directly connected to the grinding part 322, which causes the height of the rough grinding component 30 and the fine grinding component 40 to be too high and interfere with the transfer component 50, thereby facilitating the stable application of the grinding equipment in the machine. In addition, by arranging the grinding portion 322 of the coarse grinding piece 32, the grinding portion 322 of the fine grinding piece 42, and the base 10 in sequence along a direction perpendicular to the movement direction of the first sliding piece 31, the grinding portion 322 of the coarse grinding piece 32 and the grinding portion 322 of the fine grinding piece 42 respectively correspond to the grinding position of the coarse grinding piece 32 and the grinding position of the fine grinding piece 42. When the transfer assembly 50 drives the workpiece 200 to move toward the base 10 in a direction perpendicular to the movement direction of the first sliding piece 31, the grinding portion 322 of the coarse grinding piece 32 and the grinding portion 322 of the fine grinding piece 42 can grind the preset area of ​​the workpiece 200 in sequence.

[0077] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the grinding part 322 includes a connecting body 3221, a grinding body 3222, a synchronous wheel 3223, a fixed body 3224 and a bearing 3225. One end of the connecting body 3221 is rotatably connected to the supporting part 321, and the grinding body 3222 is connected to the other end of the connecting body 3221. The grinding body 3222 is driven by the connecting body 3221 to rotate and is used to grind the workpiece 200. The synchronous wheel 3223 is sleeved on the connecting body 3221, and the belt 324 is sleeved on the outer periphery of the synchronous wheel 3223. The synchronous wheel 3223 drives the connecting body 3221 and the grinding body 3222 to rotate synchronously under the drive of the belt 324. The fixed body 3224 is located between the grinding body 3222 and the synchronous wheel 3223 and is connected to the supporting part 321. The fixed body 3224 is sleeved on the connecting body 3221 and is provided with a receiving groove 3224a. The bearing 3225 is arranged in the receiving groove 3224a and is sleeved on the connecting body 3221. Exemplarily, the grinding body 3222 can be a grinding wheel, and the bearing 3225 can be a radial ball bearing. It can be understood that the grinding drive part 323 is composed of a variable frequency motor and a driving wheel, the variable frequency motor is arranged on the first sliding member 31 and connected to the driving wheel, and the belt 324 is sleeved on the driving wheel and the synchronous wheel 3223, so that the grinding drive part 323, the belt 324 and the synchronous wheel 3223 constitute the belt 324 transmission mechanism. It can be understood that the number of bearings 3225 can be multiple, and multiple bearings 3225 are stacked in the receiving groove 3224a to withstand radial loads and smaller axial loads from any upward direction, so that the connecting body 3221 can stably drive the grinding part 322 to rotate.

[0078] Thus, by providing the above-mentioned connecting body 3221, grinding body 3222 and synchronous wheel 3223, the synchronous wheel 3223, belt 324 and grinding drive unit 323 can form a belt 324 transmission mechanism, thereby utilizing the characteristics of the belt 324 transmission mechanism of running smoothly and mitigating load impact, so that the grinding drive unit 323 can stably drive the synchronous wheel 3223 to rotate through the belt 324, and then the grinding unit 322 can stably grind the workpiece 200, thereby improving the grinding stability of the rough grinding assembly 30 and the fine grinding assembly 40. In addition, by providing the above-mentioned fixed body 3224 and bearing 3225, the bearing 3225 can separate the fixed body 3224 and the connecting body 3221, so as to prevent the connecting body 3221 from being unable to rotate due to a large friction force, so that the connecting body 3221 can stably drive the grinding body 3222 to rotate, further improving the grinding stability.

[0079] See also Figure 2In some embodiments, the placement member 11 includes a placement portion 113, two connecting portions 114, and two limiting portions 115. The placement portion 113 is provided with a placement groove 111 and a receiving groove 112. The two connecting portions 114 are arranged in the receiving groove 112 at intervals along the extension direction of the screw rod 22 and are respectively rotatably connected to the two ends of the screw rod 22. The two limiting portions 115 are arranged between the two connecting portions 114 at intervals and are both connected to the placement portion 113. The two limiting portions 115 respectively abut against the first sliding member 31 and the second sliding member 41 moving in opposite directions to limit the movement distance of the first sliding member 31 and the second sliding member 41.

[0080] In this way, the two connecting parts 114 are rotatably connected to the two ends of the screw rod 22 respectively, so that the two connecting parts 114 can support the screw rod 22, so that the screw rod 22 can stably rotate in the storage groove 112, so that the screw rod 22 can stably drive the rough grinding assembly 30 and the fine grinding assembly 40 to move toward each other, thereby improving the driving stability of the screw rod 22. In addition, by providing the above-mentioned two limiting parts 115, when the grinding device 100 completes the grinding operation, the rotating driving member 21 drives the screw rod 22 to drive the rough grinding assembly 30 and the fine grinding assembly 40 to move in opposite directions, so that the two limiting parts 115 respectively abut against the first sliding member 31 and the second sliding member 41 moving in opposite directions, thereby limiting the movement distance of the first sliding member 31 and the second sliding member 41, preventing the first sliding member 31 and the second sliding member 41 from moving too far and leaving the slide rail 12, so that the rough grinding assembly 30 and the fine grinding assembly 40 can repeat the grinding operation.

[0081] See also Figure 2 and Figure 3 In some embodiments, the placement member 11 is provided with an idle position 116 and an operating position 117 at intervals along the extension direction of the screw rod 22, the idle position 116 is adjacent to the rotating drive member 21 relative to the operating position 117, the base 10 further includes a first detection member 14 and a second detection member 15, the first detection member 14 and the second detection member 15 are respectively arranged at the idle position 116 and the operating position 117 and are both connected to the placement member 11, the first detection member 14 and the second detection member 15 are respectively electrically connected to the rotating drive member 21, and the first detection member 14 and the second detection member 15 are used to detect the positions of the first sliding member 31 and the second sliding member 41 respectively. Specifically, the first sliding member 31 and the second sliding member 41 each include a sliding portion 311 and a metal portion 312, the sliding portion 311 is slidably connected to the slide rail 12, and the metal portion 312 is located on one side of the placement member 11 and is connected to the sliding portion 311. Exemplarily, the first detection member 14 and the second detection member 15 can be metal sensors, and the metal portion 312 can be any metal body, metal block or similar metal plate that can be detected by the metal sensor.

[0082] When the first detection member 14 detects that the metal part 312 of the rough grinding assembly 30 has moved to the idle position 116, the first detection member 14 forms detection information and sends it to the rotating drive member 21 through an electrical signal. The rotating drive member 21 stops driving the screw rod 22 to continue rotating based on the detection information of the first detection member 14, so that the rough grinding assembly 30 and the fine grinding assembly 40 stop moving away from each other, thereby preventing the rough grinding assembly 30 and the fine grinding assembly 40 from detaching from the screw rod 22; when the second detection member 15 detects that the metal part 312 of the fine grinding assembly 40 has moved to the working position 117, the second detection member 15 forms detection information and sends it to the rotating drive member 21 through an electrical signal. The rotating drive member 21 stops driving the screw rod 22 to continue rotating based on the detection information of the second detection member 15, so that the rough grinding assembly 30 and the fine grinding assembly 40 stop moving toward each other, thereby avoiding the collision between the rough grinding assembly 30 and the fine grinding assembly 40. In this way, by setting the above-mentioned first detection member 14 and the second detection member 15 to respectively detect the positions of the first sliding member 31 and the second sliding member 41, and respectively transmit their detection information to the rotating driving member 21 through electrical signals, so that the rotating driving member 21 stops driving the screw rod 22 to continue rotating based on the corresponding detection information, so that the rough grinding component 30 and the fine grinding component 40 can stably loosen the grinded workpiece 200, or the rough grinding component 30 and the fine grinding component 40 can be stably adjusted to the preset spacing, which is beneficial to ensure the grinding stability of the rough grinding component 30 and the fine grinding component 40.

[0083] See also Figure 2 In some embodiments, the base 10 further includes a flexible protective member 16, and opposite ends of the flexible protective member 16 are respectively connected to the first sliding member 31 and the second sliding member 41, and the flexible protective member 16 is used to cooperate with the first sliding member 31 and the second sliding member 41 to cover the storage groove 112. Exemplarily, the flexible protective member 16 can be an accordion cover, so that the flexible protective member 16 is folded or stretched when the first sliding member 31 and the second sliding member 41 move toward or away from each other, so that the flexible protective member 16 always covers the storage groove 112.

[0084] In this way, by connecting the two ends of the flexible protective member 16 to the first sliding member 31 and the second sliding member 41 respectively, the flexible protective member 16 and the first sliding member 31 and the second sliding member 41 can cooperate with each other to cover the storage groove 112, thereby preventing debris generated when the workpiece 200 is polished from accumulating in the storage groove 112 and interfering with the normal operation of the screw 22, the first sliding member 31 and the second sliding member 41, which is beneficial to maintaining the polishing device 100 to continuously and stably polish the workpiece 200.

[0085] See also Figure 3In some embodiments, the rough grinding assembly 30 further includes a protective cover 33, which covers at least a portion of the support portion 321, the grinding drive portion 323 and the grinding portion 322 and is connected to the first sliding member 31. It can be understood that the fine grinding assembly 40 also includes a protective cover 33.

[0086] In this way, by providing the above-mentioned protective cover 33, the protective cover 33 can protect the corresponding grinding components, prevent the debris generated by the coarse grinding piece 32 and the fine grinding piece 42 grinding the workpiece 200 from flying around, and improve the grinding stability.

[0087] See also Figure 2 In some embodiments, the rotary drive member 21 includes a driving portion 211 and a linkage portion 212. The driving portion 211 is disposed in the placement groove 111 and extends into the receiving groove 112, the linkage portion 212 is located in the receiving groove 112, and the two ends of the linkage portion 212 are respectively connected to the driving portion 211 and the screw rod 22, and the linkage portion 212 is used to drive the screw rod 22 to rotate under the drive of the driving portion 211. Exemplarily, the driving portion 211 can be a servo motor, and the linkage portion 212 can be a coupling.

[0088] In this way, by setting the above-mentioned linkage part 212 as a coupling, the linkage part 212 can coaxially connect the driving part 211 and the screw rod 22, so that the driving part 211 can stably drive the screw rod 22 to rotate through the linkage part 212, and then the screw rod 22 can stably drive the coarse grinding component 30 and the fine grinding component 40 to move toward each other, thereby improving the driving stability of the driving component 20.

[0089] See also Figure 2 and Figure 6 In some embodiments, the screw rod 22 includes a main body 221, a first threaded portion 222, and a second threaded portion 223. The main body 221 is rotatably connected to the base 10 and connected to the rotary drive member 21. The first threaded portion 222 and the second threaded portion 223 are spaced apart at the outer periphery of the main body 221 and are threadedly connected to the first sliding member 31 and the second sliding member 41, respectively. The thread directions of the first threaded portion 222 and the second threaded portion 223 are opposite. The first threaded portion 222 and the second threaded portion 223 are used to drive the first sliding member 31 and the second sliding member 41 to move toward or away from each other under the drive of the main body 221. Exemplarily, any one of the first threaded portion 222 and the second threaded portion 223 is a right-hand thread, and the other is a left-hand thread.

[0090] When the main body 221 rotates along a preset direction, the first threaded portion 222 and the second threaded portion 223 respectively drive the first sliding member 31 and the second sliding member 41 to move toward each other under the drive of the main body 221. When the main body 221 rotates along a direction opposite to the preset direction, the first threaded portion 222 and the second threaded portion 223 respectively drive the first sliding member 31 and the second sliding member 41 to move away from each other under the drive of the main body 221. In this way, by setting the thread directions of the first threaded portion 222 and the second threaded portion 223 to be opposite, the screw rod 22 can drive the first sliding member 31 and the second sliding member 41 threadedly connected to the screw rod 22 to move toward each other or away from each other synchronously, so that the rough grinding assembly 30 and the fine grinding assembly 40 can be quickly adjusted to the preset spacing or loosen the workpiece 200 after grinding, thereby improving the grinding stability.

[0091] The working process of the above-mentioned grinding device 100 is roughly as follows:

[0092] First, the transfer assembly 50 drives the clamped workpiece 200 to move toward the base 10 to a preset height, and the rotary drive member 21 drives the screw rod 22 to rotate in a preset direction, so that the screw rod 22 drives the first sliding member 31 and the second sliding member 41 to move toward each other to a preset distance, so that the coarse grinding member 32 and the fine grinding member 42 respectively abut against the opposite sides of the workpiece 200, so as to respectively support the two sides of the workpiece 200, thereby preventing the workpiece 200 from being deformed due to unidirectional force during grinding, thereby improving the grinding accuracy;

[0093] Then, the transfer assembly 50 drives the clamped workpiece 200 to continue to move closer to the base 10. Since the grinding portion 322 of the rough grinding member 32, the grinding portion 322 of the fine grinding member 42 and the base 10 are sequentially arranged in a direction perpendicular to the movement direction of the first sliding member 31, the rough grinding member 32 and the fine grinding member 42 sequentially grind the preset area of ​​the workpiece 200, thereby quickly completing the rough and fine grinding operation on the workpiece 200, without manual operation to perform rough and fine grinding on the workpiece 200 one by one, thereby improving the grinding efficiency;

[0094] Finally, the rotating drive member 21 drives the screw rod 22 to rotate in a direction opposite to the preset direction, so that the screw rod 22 drives the first sliding member 31 and the second sliding member 41 to move in opposite directions, so that the coarse grinding member 32 and the fine grinding member 42 are simultaneously loosened from the grinded workpiece 200, and then the transfer assembly 50 drives the workpiece 200 to move away from the base 10, and the operator removes the grinded workpiece 200 from the transfer assembly 50.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
