Description

Technical Field

[0001] This application relates to the field of material receiving technology, and in particular to a material receiving device for a centerless grinder. Background Technology

[0002] A centerless grinder is a type of grinder that does not require a workpiece axis for positioning during grinding. It mainly consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel performs the actual grinding work, the adjusting wheel controls the rotation of the workpiece and the feed rate, and the workpiece support supports the workpiece during grinding. On a centerless cylindrical grinder, the workpiece is not centered or supported by a center; instead, it is placed between the grinding wheel and the guide wheel and supported by a support plate and the guide wheel. After grinding, the workpiece needs to be retrieved. To facilitate this, a centerless grinder retrieval device is usually used.

[0003] A search revealed a patent document with authorization announcement number CN222371106U, which discloses a material receiving device for a centerless grinder. The device includes a guide wheel assembly, a grinding wheel assembly placed behind the guide wheel assembly, and a support plate assembly placed in the middle of the guide wheel assembly and the grinding wheel assembly. A collection component is located at the right end of the guide wheel assembly, and a pushing component is located at the left end. By using the collection component, when ground material needs to be collected, the material falls onto the upper end of the support plate. Cooling water adhering to the outside of the material flows through a drain hole into a water tank, preventing the material from being continuously soaked in liquid. If the support plate is damaged and needs replacement, pulling the first handle removes the support plate for easy replacement. The material rolls through the support plate to the rear of the baffle, where the spring force reduces the impact, preventing damage to the material. When too much cooling water accumulates in the water tank, turning the knob removes the threaded rod, allowing the liquid to drain.

[0004] In practical use, it was found that the existing device cannot automatically transport and collect workpieces, which increases the labor intensity of workpiece collection and thus affects work efficiency. Therefore, we proposed a collection device for centerless grinders to solve the above problems. Utility Model Content

[0033] Specifically, the striking mechanism includes a rubber rod 304 and a vibrating plate 305. The rubber rod 304 is fixedly installed at the bottom of the conveying shaft 302 and is located outside the conveying chamber 3. The vibrating plate 305 is fixedly installed at the bottom of the guide chute 103 and is compatible with the rubber rod 304 and the vibrating plate 305.

[0034] Specifically, the processing mechanism includes a guide wheel device body 101 and a grinding wheel device body 102. The top of the centerless grinder body 1 is provided with the guide wheel device body 101 and the grinding wheel device body 102. The guide wheel device body 101 is located in front of the grinding wheel device body 102, and the guide groove 103 is located between the guide wheel device body 101 and the grinding wheel device body 102.

[0035] Specifically, a common water filter pipe 7 is provided between the conveying chamber 3 and the filter box 2, and a water filter screen 701 is installed inside the water filter pipe 7.

[0036] Specifically, the water supply mechanism includes a water pump 4 and a water supply pipe 401. The water pump 4 is installed on the front side of the filter box 2, and the water supply pipe 401 is installed on the top of the water pump 4. The water pump 4 and the filter box 2 are connected by the same connecting pipe, which is located below the mounting base 201.

[0037] Specifically, the top of the guide wheel device body 101 and the grinding wheel device body 102 are fixedly installed with the same water storage tank 5, and the top of the water supply pipe 401 is connected to the right side of the water storage tank 5.

[0038] Specifically, a nozzle is installed at the bottom of the water storage tank 5, and the nozzle is compatible with the main body 101 of the guide wheel device and the main body 102 of the grinding wheel device.

[0039] Specifically, a door is provided on the rear side of filter box 2.

[0040] In this application, when the centerless grinder body 1 is running, the guide wheel device body 101 and the grinding wheel device body 102 on its top cooperate with each other to perform precise grinding on the workpiece. During the processing, in order to reduce the heat generated by grinding and prevent the workpiece from deforming due to overheating, the nozzle at the bottom of the water tank 5 continuously sprays coolant into the processing area, while washing away impurities generated by grinding. During the processing, the workpiece and coolant can enter the conveying chamber 3 through the feed inlet 6 at the top of the conveying chamber 3 along the guide groove 103 between the guide wheel device body 101 and the grinding wheel device body 102. At this time, the motor 301 on the right side of the conveying chamber 3 starts to work, and its output shaft drives the conveying shaft 302 to rotate at high speed. The spiral blades 303 installed on the conveying shaft 302 also rotate accordingly. The rotation of the spiral blades 303 forms a spiral conveying channel, which can realize the conveying and collection of workpieces. Under the push of the spiral blades 303, the workpiece is smoothly moved along the axial direction of the conveying chamber 3 to the discharge pipe 8 on the bottom right side of the conveying chamber 3, and finally discharged from the device through the discharge pipe 8. This facilitates the subsequent centralized processing of workpieces, thereby realizing the orderly collection of workpieces, avoiding the accumulation of workpieces in the device, and improving the processing efficiency and production continuity. Meanwhile, within the conveying chamber 3, coolant flows through the filter screen 701 in the filter pipe 7 into the filter box 2. The filter element 202 in the filter box 2 further refines the coolant, removing tiny suspended solids and impurities, bringing it to a level suitable for reuse. The filtered, clean coolant is then pumped through a connecting pipe by the water pump 4 at the front of the filter box 2 and transported through the water pipe 401 to the water storage tank 5 at the top of the guide wheel device body 101 and the grinding wheel device body 102. The coolant in the water storage tank 5 is then sprayed back onto the processing area through nozzles at the bottom, achieving water conservation, reducing production costs, ensuring a continuous supply of coolant during processing, and improving processing quality and stability. During the rotation of the conveyor shaft 302, the rubber rod 304 fixed at its bottom will rotate synchronously with the conveyor shaft 302; during the rotation, the rubber rod 304 will periodically strike the vibrating plate 305 at the bottom of the guide trough 103; the high-frequency vibration generated by the striking can effectively prevent the workpiece or sticky impurities from adhering to the inner wall of the guide trough 103, and can ensure the unobstructed flow of the guide trough 103 and the conveying channel, so as to ensure that the workpiece and coolant can smoothly enter the conveying chamber 3; In addition, the door located at the rear of the filter box 2 plays an important role. As the filtration process continues, a large amount of impurities will be trapped inside the filter box 2, and the filtration performance of the filter element 202 will decrease with the increase of usage time. At this time, the operator can open the door to easily clean the impurities trapped inside the filter box 2 and replace the filter element 202, thereby ensuring that the filtration mechanism always maintains high-efficiency filtration performance, maintains the stable operation of the entire material receiving device, and extends the service life of the device.
