Description

Technical Field

[0001] This utility model relates to the field of blade sharpening devices, and in particular to an adjustable sharpening device and its sharpening head machine. Background Technology

[0002] The blades used for shredding vegetables have overlapping V-shaped grooves at the cutting edge, which allows the vegetable shreds to slide out from the cutting edge during the shredding process. They are mainly shaped by milling and then heat-treated to give the blades sufficient hardness and toughness.

[0003] Chinese utility model patent (authorization announcement number: CN219901396U) discloses a CBN cutting tool grinding fixture, including a placement table, a plate on the top of the placement table, a fixed seat on the upper side of the plate, a motor on the left side of the fixed seat, an internal output shaft of the motor passing through the fixed seat, a grinding wheel at the end of the internal output shaft of the motor, and a clamping mechanism on the front side of the fixed seat. When using this device, the CBN cutting tool needs to be fixed inside the clamp first. After the adjustment table is rotated to the specified tilt angle, the adjustment table is fixed by the fixing screw sleeve. The motor is started, driving the grinding wheel to rotate, pushing the clamp and moving the CBN cutting tool towards the grinding wheel, thus grinding the CBN cutting tool at a specific angle.

[0004] However, in actual use, the grinding wheel grinds the blade from only one position during the grinding process. Since the blade is a thin product, it is necessary to control the heat generation and ensure uniform grinding of the blade during grinding. However, the grinding wheel contacts the blade from only one position, which makes it easy to wear and not durable. As a result, after long-term use, there are differences in the grinding surface of the grinding wheel, which makes it impossible for the grinding wheel to achieve the grinding effect of the blade to meet the quality requirements of the finished product, thus affecting the actual production and processing.

[0048] Detailed implementation method.

[0049] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] Please see Figures 1-2 In this embodiment of the present invention, an adjustable grinding device is provided. The grinding device includes a first rotating motor 11, a connecting seat 12, a connecting rod 13, a grinding wheel conveyor belt 14, an eccentric bushing 16, and a second rotating motor 15. The output end of the first rotating motor 11 is connected to one end of the grinding wheel conveyor belt 14 to drive the grinding wheel conveyor belt 14 to rotate. The first rotating motor 11 is detachably mounted on the upper end of the connecting seat 12. One end of the connecting rod 13 is hinged to the left side of the connecting seat 12, and the other end of the connecting rod 13 is hinged to the end face of the eccentric bushing 16. The output end of the second rotating motor 15 is detachably connected to the eccentric bushing 16 to drive the eccentric bushing 16 to rotate.

[0051] The working principle of this embodiment is as follows: The operator powers on the first rotating motor 11, which drives the grinding wheel conveyor belt 14 to convey the workpiece. The outer surface of the grinding wheel conveyor belt 14 serves as the grinding section for the workpiece. Grinding the workpiece is completed by contacting the part to be ground with the outer surface of the grinding wheel conveyor belt 14. At the same time, the operator powers on the second rotating motor 15, which drives the eccentric bushing 16 to rotate. One end of the connecting rod 13 rotates with the eccentric bushing 16, causing the connecting rod 13 to shift the position of the connecting seat 12. The first rotating motor installed at the connecting seat 12 also shifts with the connecting seat 12, thereby shifting the position of the grinding wheel conveyor belt 14. During the grinding process, the continuous shift of the grinding wheel conveyor belt 14 ensures that the grinding surface of the grinding wheel conveyor belt 14 evenly contacts the part of the workpiece to be ground, making the grinding wheel conveyor belt 14 more durable and less prone to damage. At the same time, the movement of the grinding wheel conveyor belt 14 can avoid overheating caused by single grinding, which would affect the processing quality, and can better control the heat generated during processing.

[0052] Further as Figures 1-2 As shown in the embodiment of this utility model, the grinding wheel conveyor belt 14 includes a grinding wheel belt 141, a first rotating wheel 142 and a second rotating wheel 143. One end of the grinding wheel belt 141 is fitted with the first rotating wheel 142, and the other end of the grinding wheel belt 141 is fitted with the second rotating wheel 143. The output end of the first rotating motor 11 is detachably connected to the first rotating wheel 142 to drive the first rotating wheel 142 to rotate.

[0053] The working principle of this embodiment is as follows: The first rotating wheel 142 has a keyway inside for mounting at the output end of the first rotating motor 11. A first bearing is set inside the second rotating wheel 143. A mounting shaft can be set at the connecting seat 12 and pass through the first bearing, so that the grinding wheel conveyor belt 14 can be mounted on one side of the connecting seat 12. When the first rotating motor 11 drives the first rotating wheel 142 to rotate, it can drive the grinding wheel belt 141 to convey. The second rotating wheel 143, as the driven wheel, also rotates under the rotation of the grinding wheel belt 141. Its working principle is the same as that of the conveyor belt, and will not be described in detail here.

[0054] Further as Figures 1-2 As shown in the embodiment of this utility model, a guide device is provided at the front end of the connecting seat 12. The guide device includes a guide sleeve 21 and a guide shaft 22. The guide sleeve 21 is detachably installed on the front end face of the connecting seat 12, and the guide shaft 22 is inserted into the guide sleeve 21 and extends toward the eccentric bushing 16.

[0055] The working principle of this embodiment is as follows: The operator powers on the second rotating motor 15 to drive the eccentric bushing 16 to rotate, so that the grinding wheel conveyor belt 14 can move when grinding the workpiece. The guide shaft 22 is set to restrict the movement of the grinding wheel conveyor belt 14 in the front and back directions. Since the connecting seat 12 and the connecting rod 13 are hinged, and the guide sleeve 21 is installed on the front end face of the connecting seat 12, the movement direction of the grinding wheel conveyor belt 14 is restricted. It can only move with the guide sleeve 21 in the direction of the guide shaft 22, so that the grinding wheel conveyor belt 14 can move left and right while fixing the front and back direction. This allows the grinding wheel conveyor belt 14 to process the cutting edge bevel of the workpiece well, while ensuring the processing quality and controlling the heat generated during grinding.

[0056] Further as Figures 3-6 As shown in the embodiment of this utility model, the grinding head machine includes a feeding platform 29 and a pushing cylinder 30. The feeding platform 29 has a feeding port 291 on the left side and a sliding groove 292 extending towards the feeding port 291 on the right side. A first slider 31 is provided in the sliding groove 292. The pushing cylinder 30 is installed on the lower end face of the feeding platform 29, and the output end of the pushing cylinder 30 is connected to the first slider 31.

[0057] The working principle of this embodiment is as follows: the workpiece to be processed is placed on the feeding table 2929 to form a stack. The pusher cylinder 30 is powered on and the output end is retracted, thereby driving the first slider 31 to move in the retraction direction. The first slider 31 pushes the lower end of the stacked workpiece so that the workpiece is sent out from the feeding port 291.

[0058] Further as Figures 7-9As shown in the embodiment of this utility model, the grinding head machine includes a clamping device, which includes a material feeding clamp 35 and a first height adjustment cylinder 32. The upper end of the material feeding clamp 35 is provided with a clamping port 33 for clamping the workpiece. The clamping port 33 of the material feeding clamp 35 is located at the lower end of the feeding port. The first height adjustment cylinder 32 is longitudinally installed on one side of the material feeding clamp 35, and the output direction of the first height adjustment cylinder 32 faces the feeding port. The output end of the first height adjustment cylinder 32 is detachably connected to the left end face of the material feeding clamp 35. Specifically, the first height adjustment cylinder 32 is longitudinally installed on one side of the material feeding clamp 35, and the output direction of the first height adjustment cylinder 32 faces the feeding port. The material feeding clamp 35 includes a first clamp 351 and a second clamp 352. The first clamp 351 is located at the lower end of the feeding port and has a through groove 3111. The second clamp 352 is detachably installed in the through groove 3111. The distance between the first clamp 351 and the second clamp 352 can serve as the clamping opening 33 of the material feeding clamp 35. The second clamp 352 has a threaded hole. The first clamp 351 has a first through hole 3112 near the threaded hole. The material feeding clamp 35 is equipped with an adjustment knob. One end of the adjustment knob is a lead screw 41, which passes through the first through hole 3112 in the first clamp 351 and is threadedly connected to the threaded hole in the second clamp 352. This allows the adjustment knob to be rotated to adjust the distance between the first clamp 351 and the second clamp 352.

[0059] The working principle of this embodiment is as follows: The operator can adjust the knob by turning it to move the first clamping plate 351 away from or closer to the second clamping plate 352, thereby increasing or decreasing the diameter of the clamping opening 33. When the workpiece to be ground falls to the clamping opening 33, the clamping opening 33 needs to be adjusted to a suitable distance so that one end of the workpiece can stand upright at the clamping opening 33 for easy gripping by the gripping device. At the same time, the first height adjustment cylinder 32 can extend to drive the unloading clamping plate 35 to rise as a whole, and when the first height adjustment cylinder 32 retracts, it can drive the unloading clamping plate 35 to descend as a whole.

[0060] Further as Figure 3 and Figure 17 As shown in the embodiment of this utility model, the feeding port is provided with a guide inclined plate 34. The upper end of the guide inclined plate 34 is detachably installed at the lower end of the feeding port 291. The lower end of the guide inclined plate 34 is close to the clamping port 33 to guide the workpiece to slide to the clamping port 33 of the unloading clamping plate 35.

[0061] Further as Figures 10-12 and Figure 20 As shown in the embodiment of this utility model, the grinding head machine includes a gripping device, which includes a lead screw 41, a threaded slider 42, and a gripper 43. The lead screw 41 is located at the upper end of the feed port, the threaded slider 42 is threadedly connected to the lead screw, and the upper end of the gripper 43 is detachably connected to the threaded slider 42.

[0062] The working principle of this embodiment is as follows: the type of lead screw 41 includes, but is not limited to, ball screw 41. The sliding trajectory of lead screw 41 and threaded slider 42 passes through the clamping device. The gripper 43 is used to grip the workpiece and transport it to the designated device. The type of gripper 43 includes, but is not limited to, magnetic suction, negative pressure suction cup, clamp and robot.

[0063] Further as Figures 11-12 As shown in the embodiment of this utility model, the gripper 43 includes a third clamping plate 431, a fourth clamping plate 432, a push plate cylinder 433, and a first spring 434. The third clamping plate 431 is provided with a guide post 435, and the fourth clamping plate 432 is provided with a guide hole 4321. The guide post 435 is slidably installed on the fourth clamping plate 432. The output end of the push plate cylinder 433 abuts against the left side of the fourth clamping plate 432. The first spring 434 is installed between the third clamping plate 431 and the fourth clamping plate 432.

[0064] Specifically, limit plates 44 are provided at the left and right ends of the gripper 43 to restrict the gripper 43 from rotating around the lead screw 41, and to provide guidance for the gripper 43 so that the gripper 43 slides stably.

[0065] The working principle of this embodiment is as follows: When the workpiece falls to the clamping port 33, the operator drives the first height adjustment cylinder 32 to extend, so that the unloading clamping plate 35 carries the workpiece to the gripping position of the gripper 43. In this embodiment, it rises to the position between the third clamping plate 431 and the fourth clamping plate 432. After the push plate cylinder 433 is energized, it drives the third clamping plate 431 to slide towards the fourth clamping plate 432 to clamp the workpiece.

The calibration platform 52 has a calibration groove 524, and the calibration wheels 53 are respectively mounted on the left and right groove surfaces of the calibration groove 524. The calibration device can be installed on the right side of the clamping device, and the gripper 43 clamps the workpiece and moves it from the clamping device to the calibration device as a stepping station.

[0067] Specifically, the upper end face of the inclined base 51 is provided with a guide rail 511, and the calibration platform 52 includes a first calibration plate 521 and a second calibration plate 522. The lower end face of the first calibration plate 521 is provided with a first guide groove 5211, and the lower end face of the second calibration plate 522 is provided with a second guide groove 5221. The first calibration plate 521 is slidably installed on the left side of the guide rail 511, and the second calibration plate 522 is slidably installed on the right side of the guide rail 511.

[0068] The calibration wheel 53 includes a first calibration roller 531 and a second calibration roller 532. A first calibration groove 5212 is opened on the right end face of the first calibration plate 521, and the first calibration rollers 531 are evenly distributed in the first calibration groove 5212. A second calibration groove 5222 is opened on the left end face of the second calibration plate 522, and the second calibration rollers 532 are evenly distributed in the second calibration groove 5222.

[0070] Further as Figures 18-19 As shown in the embodiment of this utility model, the grinding head machine includes a precision calibration device 6. The precision calibration device 6 is located on the sliding track of the gripper and one side is close to the calibration device.
