Description

Technical Field

[0001] This utility model relates to the field of resin grinding wheel technology, and in particular to an automatic detection and sorting device for the concentricity of resin grinding wheels after curing. Background Technology

[0002] Resin grinding wheels are grinding tools. They use resin as a binder and contain abrasives and fillers. Resin grinding wheels have the advantages of high strength, good elasticity, and excellent surface finish. They can be widely used in the cutting, fine grinding, and polishing of metal and non-metal materials. The concentricity of a resin grinding wheel is a technical indicator that measures the degree to which the center or axis of the resin grinding wheel coincides with the reference center / axis. In order to improve the safety of using resin grinding wheels, it is necessary to test the concentricity of the cured resin grinding wheel. This requires the use of an automatic detection and sorting device for the concentricity of cured resin grinding wheels.

[0003] A search revealed that Chinese Patent CN112170275A discloses an automatic detection and sorting device for the concentricity of thrust bearings. The device includes a main unit, which contains an execution chamber, a bearing groove opening to the right and communicating with the execution chamber, an insertion chamber located below the execution chamber and communicating with its upper end, a right-angle transmission chamber located to the left of the insertion chamber, and a belt chamber located slightly below. A hydraulic cylinder is fixedly connected to the main unit within the right wall of the execution chamber. The hydraulic cylinder is powered by a piston rod, the upper end of which passes through the main unit to the outside and is fixedly connected to a lifting plate. The thrust bearing to be tested is fed into the device via a track. The concentricity of the bearing is detected by the extension and retraction of the hydraulic rod. The process is simple and effective; the device automatically determines whether the bearing meets tolerance requirements after one rotation and automatically places the bearing into the corresponding frame when the hydraulic rod rises.

[0004] The above technical solution can only automatically detect concentricity through the use of hydraulic rods and bearings. It cannot continuously and automatically sort and transport different workpieces after detection. This can easily lead to problems such as workpiece mixing and long pauses in the sorting process, resulting in low efficiency in workpiece sorting and transport. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0027] In order to solve the problems existing in the background technology, this application proposes the following technical solution: an automatic detection and sorting device for the concentricity of resin grinding wheels after curing.

[0028] The specific technical solution includes a processing table 1, a feeding assembly 2, and a material distribution assembly 3;

[0029] like Figure 1-3 As shown, the unloading assembly 2 is mounted on the processing table 1. The unloading assembly 2 is used to unload the grinding wheel. The unloading assembly 2 includes a linear cylinder 201, a servo motor 202, and a push rod 203. The linear cylinder 201 can drive the servo motor 202 to move horizontally, and the servo motor 202 can drive the push rod 203 to rotate. The push rod 203 can pull the spring telescopic rod 406. The fixed end of the linear cylinder 201 is fixedly mounted on the processing table 1. The telescopic end of the linear cylinder 201 is fixedly connected to the machine tool 202, and the push rod 203 is fixedly connected to the output shaft of the servo motor 202. A qualified hopper 204 and a waste hopper 205 are installed below the linear cylinder 201. The qualified hopper 204 can conveniently limit qualified grinding wheels, and the waste hopper 205 can limit unqualified grinding wheels. The qualified hopper 204 and the waste hopper 205 are fixedly installed on the processing table 1. The material distribution assembly 3 is installed on the processing table 1. The material sorting assembly 3 is used for sorting and conveying grinding wheels. The material sorting assembly 3 includes a second servo motor 301, a first roller 302, a second roller 303, and a first conveyor belt 304. The second servo motor 301 drives the first roller 302 to rotate. The first roller 302 and the second roller 303 support the first conveyor belt 304. The rotation of the first conveyor belt 304 conveys the grinding wheels. The second servo motor 301 is fixedly mounted on the processing table 1. The first roller 302 and the second servo motor 303... The output shaft of 301 is fixedly connected. Roller 1 302 and roller 2 303 are rotatably mounted on the processing table 1. Conveyor belt 1 304 is sleeved on the outside of roller 1 302 and roller 2 303. An isolation belt 305 is fixedly sleeved on the outer center of conveyor belt 1 304. The isolation belt 305 can separate qualified grinding wheels and unqualified grinding wheels on conveyor belt 1 304. Qualified hopper 204 and waste hopper 205 are located on both sides above the isolation belt 305.

[0030] according to Figure 1 and Figure 2 As shown, the grinding wheel is sleeved on the bracket 405, and its sidewall passes through the clamping plate 407. When the detection component 5 detects that the grinding wheel is qualified, the grinding wheel moves to the qualified hopper 204. At this time, the linear cylinder 201 retracts, which drives the servo motor 202 to move. The servo motor 202 drives the push rod 203 to move. The push rod 203 pulls the extension end of the spring telescopic rod 406. The extension end of the spring telescopic rod 406 pushes the clamping plate 407 away from the bracket 405. The linear cylinder 201 can move the grinding wheel towards the qualified hopper 204, and can remove the grinding wheel mounted on the support 405 and put it into the qualified hopper 204. The grinding wheel can fall from the support 405 into the qualified hopper 204 and fall to the left side of the isolation belt 305 on the conveyor belt 304. When the detection component 5 detects that the grinding wheel is unqualified, the linear cylinder 201 drives the push rod 203 to reset through the servo motor 202. At this time, the spring telescopic rod 406 can automatically move with the push rod 203. Upon resetting, the defective grinding wheel moves to one side of the waste hopper 205. The servo motor 202 is activated, driving the push rod 203 to rotate clockwise. When the end of the push rod 203 away from the servo motor 202 rotates to the side of the spring telescopic rod 406 away from the waste hopper 205, according to the retraction steps of the linear cylinder 201 described above, the defective grinding wheel is pushed off the bracket 405. Then, the defective grinding wheel falls through the waste hopper 205 onto the conveyor belt 304. The defective grinding wheels are located on the right side of the isolation belt 305. By starting the servo motor 301, the roller 302 is driven to rotate. The roller 302 drives the conveyor belt 304 to rotate. The conveyor belt 304 drives the roller 303 and the isolation belt 305 to rotate. The conveyor belt 304 can simultaneously classify and transport qualified and unqualified grinding wheels. The length of the conveyor belt 304 can be set as needed. A storage structure can be set below the conveyor belt 304 to store the grinding wheels separately.

[0031] like Figure 1 and Figure 4As shown, a conveying assembly 4 is installed on the processing table 1. The conveying assembly 4 is used to convey the grinding wheel. The conveying assembly 4 includes a servo motor 401, a roller 402, a roller 403, and a conveyor belt 404. The servo motor 401 can drive the roller 402 to rotate. The rollers 402 and 403 can support the conveyor belt 404. The conveyor belt 404 can convey the support 405. The roller 402 is fixedly connected to the output shaft of the servo motor 401. Conveyor belt 2 404 is sleeved on the outside of roller 3 402 and roller 403. A bracket 405 is fixedly installed on conveyor belt 2 404. The bracket 405 can support the grinding wheel. A spring telescopic rod 406 is installed on the side wall of the bracket 405. The spring telescopic rod 406 can support the clamping plate 407. The telescopic end of the spring telescopic rod 406 is fixedly installed with the clamping plate 407. The clamping plate 407 can limit the side wall of the grinding wheel and prevent the grinding wheel from accidentally falling off the bracket 405.

[0032] By pulling the clamping plate 407, the clamping plate 407 pulls the spring telescopic rod 406, causing the spring telescopic rod 406 to extend. The side wall of the grinding wheel passes through the clamping plate 407, and then the through hole in the middle part of the grinding wheel is fitted onto the end of the bracket 405. Releasing the grinding wheel causes the spring telescopic rod 406 to reset, which in turn causes the clamping plate 407 to reset. The clamping plate 407 then allows the grinding wheel to be fitted onto the bracket 405, preventing the grinding wheel from falling off. Figure 1 As shown, by starting the servo motor 401, the roller 402 is driven to rotate. The roller 402 drives the conveyor belt 404 to rotate counterclockwise. The conveyor belt 404 drives the roller 403 to rotate counterclockwise. At the same time, the conveyor belt 404 can drive the support 405 on the upper right to move to the left. The support 405 on the upper right drives the spring telescopic rod 406 on the upper right to move to the left. The support 405 and the spring telescopic rod 406 simultaneously drive the grinding wheel and clamp 407 on the upper right to move to the left. The grinding wheel can pass under the slide rail 501 and move to the left, thus conveying the grinding wheel to be inspected.

[0033] like Figure 1 and Figure 5 As shown, a detection component 5 is installed on the processing table 1. The detection component 5 is used to detect the concentricity of the grinding wheel. The detection component 5 includes a slide rail 501, a servo motor 502, and a roller 503. The slide rail 501 can fix the servo motor 502. The servo motor 502 can drive the roller 503 to rotate. The roller 503 can drive the grinding wheel below the slide rail 501 to rotate. The slide rail 501 is fixedly installed on the processing table 1. The servo motor 502 is fixedly installed on the side wall of the slide rail 501. The roller 503 is fixedly connected to the output shaft of the servo motor 502. An infrared rangefinder 504 is fixedly installed inside the slide rail 501. The infrared rangefinder 504 can detect the grinding wheel.

[0034] When the grinding wheel passes under the slide rail 501, it is positioned above the roller 503. At this time, the infrared rangefinder 504 is positioned above the grinding wheel under the slide rail 501. When the grinding wheel is completely below the slide rail 501, the infrared light emitted by the infrared rangefinder 504 can initially record the distance between the top edge of the grinding wheel and the rangefinder 504. By activating the servo motor 502, the roller 503 rotates, which in turn drives the grinding wheel under the slide rail 501 to rotate. After the grinding wheel rotates, each point on its edge rotates to the top in sequence. The infrared rangefinder 504 can record the position of each point on the edge of the grinding wheel multiple times. Since the distance between the infrared rangefinder 504 and the central axis of the grinding wheel remains unchanged, when the distance recorded by the infrared rangefinder 504 to the edge of the grinding wheel changes, it indicates that the radius of the grinding wheel has changed, and therefore the concentricity of the grinding wheel has changed. When the recorded concentricity value is within the qualified range, the grinding wheel is qualified; when the concentricity exceeds the qualified range, the grinding wheel is unqualified.

[0035] like Figure 1 As shown, a base 6 is fixedly installed on the processing table 1. The base 6 can fix the servo motor 3 401. The servo motor 3 401 is fixedly installed on the base 6. The roller 3 402 and roller 403 are rotatably installed on the base 6. The base 6 can support the roller 3 402 and roller 403.

[0036] like Figure 1 As shown, a support plate 7 is fixedly installed on the side wall of the processing table 1. The support plate 7 can support the upper part of the straight conveyor belt 404 between roller 3 402 and roller 403, preventing the upper part of the conveyor belt 404 from falling down and causing the distance between the grinding wheel and the infrared rangefinder 504 to change. The support plate 7 is inserted inside the conveyor belt 404.
