Description

Technical Field

[0001] This utility model relates to the field of cutting blade sharpening technology, and in particular to a high-precision cutting blade sharpening fixture. Background Technology

[0002] A cutting blade is a tool used to cut various materials. Among them, the most common type is the circular disc cutting blade, which is often used for cutting metal pipes, processing building materials, cutting wood, medical applications, and processing electronic components, etc.

[0003] The manufacturing process of a circular disc-shaped cutting blade generally involves first selecting a suitable metal sheet as raw material, then forging the raw material into its initial shape, followed by edge-sharpening, then heat treatment to improve hardness and wear resistance, and finally surface chrome plating.

[0004] When sharpening a circular disc-shaped raw material plate, a tooling structure is required. Generally, the circular disc-shaped raw material plate is clamped by the tooling before the sharpening operation is performed.

[0005] Currently, existing tooling for circular disc-shaped raw material plates has weak pressing stability. Moreover, it produces metal slag accumulation during sharpening, affecting the sharpening operation. Furthermore, the sharpening table has low stability during horizontal rotation. All of these factors significantly reduce the high precision required for sharpening circular disc-shaped raw material plates using tooling.

[0006] The above problems are widespread and urgently need to be improved. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a high-precision cutting tool sharpening fixture.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Design a high-precision cutting blade sharpening fixture, including a fixture base plate, a stepper motor and a fixture frame on the fixture base plate, a pressing cylinder and a sharpening cylinder on the fixture frame, a sharpening table on the stepper motor, a slag collection groove on the sharpening table, a raw material plate on the sharpening table, a guide block and a control box on the fixture frame, a guide arc groove on the guide block, an air pump and a slag storage box on the fixture frame, a slag suction pipe and a box door on the slag storage box, a pressure plate on the pressing cylinder, an anti-slip pad on the pressure plate, and a sharpening blade on the sharpening cylinder.

[0010] Furthermore, the motor shaft of the stepper motor is fixedly installed at the bottom end of the blade-sharpening table, and the vertical center axis of the motor shaft of the stepper motor coincides with the vertical center axis of the pressure plate.

[0011] Furthermore, the guide blocks are two symmetrical blocks, the top view of the guide arc groove is an arc-shaped inner groove, and the guide arc groove is slidably engaged with the cutting edge table.

[0012] Furthermore, an air pipe is provided between the air pump and the slag storage box, the slag storage box has a hollow cavity and is connected to the air pipe and the slag suction pipe, and a slag-blocking net is provided inside the slag storage box.

[0013] Furthermore, the pressure plate and the anti-slip pad have a circular cross-section when viewed from above, and the anti-slip pad is made of hard vulcanized rubber with a thickness of 20 to 30 millimeters.

[0014] Furthermore, the box door is provided with a screw pin, which passes through the box door and is threadedly connected to the slag storage box, and the slag storage box is provided with a slag discharge port.

[0015] Furthermore, the top view of the slag collection trough is a ring-shaped open groove, and the end of the slag suction pipe facing the slag collection trough is a diffuser-shaped horn structure.

[0016] The high-precision cutting tool sharpening fixture proposed in this utility model has the following advantages:

[0017] 1. This utility model improves the pressing stability of circular disc-shaped raw material plates by setting a pressure plate with anti-slip pads on the tooling frame, setting a slag removal and storage structure on the tooling frame, and symmetrically setting guide blocks with guide arc grooves on the tooling frame. This not only improves the pressing stability of circular disc-shaped raw material plates, but also effectively and completely removes and stores the metal slag generated during sharpening, without affecting the subsequent sharpening operation. At the same time, it improves the stability of the sharpening table when rotating horizontally, thereby improving the overall high precision of sharpening circular disc-shaped raw material plates with tooling.

[0018] 2. This utility model provides a door and a slag discharge port structure on the slag storage box, and provides screws on the door, which allows for convenient cleaning of the metal slag stored in the slag storage box. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 A high-precision cutting blade sharpening fixture includes a fixture base plate 1, a stepper motor 11 and a fixture frame 2 on the fixture base plate 1, a pressing cylinder 4 and a sharpening cylinder 5 on the fixture frame 2, a sharpening table 3 on the stepper motor 11, a slag collection groove 31 on the sharpening table 3, a raw material plate 32 on the sharpening table 3, a guide block 21 and a control box 23 on the fixture frame 2, a guide arc groove 22 on the guide block 21, an air pump 7 and a slag storage box 6 on the fixture frame 2, a slag suction pipe 61 and a box door 62 on the slag storage box 6, a pressure plate 41 on the pressing cylinder 4, an anti-slip pad 42 on the pressure plate 41, and a sharpening blade 51 on the sharpening cylinder 5. The raw material plate 32 is a circular metal raw material plate for a circular disc-shaped cutting blade, which is existing technology.

[0027] The sharpening blade 51 is a blade body used for sharpening round metal raw materials for use with circular disc-shaped cutting blades, and is existing technology.

[0028] The control box 23 has a built-in PLC that can precisely control the opening and closing of the stepper motor 11, the pressing cylinder 4, the blade-sharpening cylinder 5, and the air pump 7.

[0029] In detail, the motor shaft of the stepper motor 11 is fixedly set at the bottom end of the sharpening table 3. The vertical center axis of the motor shaft of the stepper motor 11 coincides with the vertical center axis of the pressure plate 41. The positioning accuracy of the motor shaft of the stepper motor 11 is high when rotating at a certain angle. Each pulse corresponds to a fixed motor shaft rotation step distance. Therefore, the stepper motor can achieve high-precision positioning, thereby ensuring the high precision of the sharpening knife 51 on the raw material plate 32 in the later stage.

[0030] Furthermore, the guide blocks 21 are two symmetrical blocks, and the top view of the guide arc groove 22 is an arc-shaped inner groove. The guide arc groove 22 is slidably engaged with the sharpening table 3. When the sharpening table 3 is driven by the stepper motor 11 to rotate slowly horizontally, the side wall of the sharpening table 3 will slide stably along the guide arc groove 22 to avoid the sharpening table 3 from tilting, thereby ensuring a high-precision sharpening effect.

[0031] Furthermore, an air pipe 71 is provided between the air pump 7 and the slag storage box 6. The slag storage box 6 has a hollow cavity and is connected to the air pipe 71 and the slag suction pipe 61. The slag storage box 6 is provided with a slag-blocking net 64. When metal slag is sucked into the slag storage box 6, the slag-blocking net 64 can block the metal slag, thereby preventing the metal slag from entering the air pump 7, while ensuring the suction and ventilation effect.

[0032] More specifically, the top view of the pressure plate 41 and the anti-slip pad 42 is a circular structure. The anti-slip pad 42 is made of hard vulcanized rubber and has a thickness of 20 to 30 millimeters. The hard vulcanized rubber material has excellent damping and anti-slip properties, is wear-resistant and durable, and further improves the stable damping and anti-slip pressing effect on the raw material plate 32.

[0033] In general, the door 62 is provided with a screw pin 63, which passes through the door 62 and is threadedly connected to the slag storage box 6. The slag storage box 6 is provided with a slag discharge port 65. The door 62 is rotatably connected to the slag storage box 6 through a preset rotating shaft, so as to realize the effect of rotating and opening the door 62.

[0034] Finally, the top view of the slag collection tank 31 is a ring-shaped open groove, and the end of the slag suction pipe 61 facing the slag collection tank 31 is a diffuser-shaped horn structure, which further improves the suction and storage of metal slag and avoids leakage.

[0035] Working method: When sharpening, first start the control box 23. The PLC in the control box 23 will control the start of the pressing cylinder 4, which will drive the pressure plate 41 to press the raw material plate 32 located in the center of the sharpening table 3 through the anti-slip pad 42. At this time, the PLC in the control box 23 will control the stop of the pressing cylinder 4 and start the sharpening cylinder 5 and the air pump 7. The air pump 7 will generate a strong suction force in the slag suction pipe 61. At the same time, the sharpening cylinder 5 will drive the sharpening blade 51 to move downward quickly and align the raw material plate 32 with the side part for rapid punching and sharpening. Then, the PLC in the control box 23 will control the sharpening cylinder 5 to drive the sharpening blade 51 to return to the starting position. At the same time, the slag suction pipe 61 will effectively and completely suck away the metal slag that falls into the slag collection tank 31 and store it in the slag storage box 6, thus completing one sharpening operation.

[0036] After a sharpening operation is completed, the PLC in the control box 23 will control the pressing cylinder 4 to move the pressure plate 41 upward a certain distance and stop pressing the raw material plate 32. Then, the PLC in the control box 23 will control the start of the stepper motor 11, which will drive the motor shaft of the stepper motor 11 to rotate slowly at a certain angle and stop. This will drive the sharpening table 3 and the raw material plate 32 to rotate slowly horizontally at a certain angle and stop. Then, the PLC in the control box 23 will control the pressing cylinder 4 to drive the pressure plate 41 to press the raw material plate 32 stably again. Then, the PLC in the control box 23 will control the sharpening cylinder 5 again to perform the next sharpening operation, and so on.

[0037] Furthermore, when the sharpening table 3 and the raw material plate 32 rotate slowly horizontally, the side wall of the sharpening table 3 will slide stably along the guide arc groove 22.

[0038] The above operations improve the overall precision of sharpening the circular disc-shaped raw material plate 32 using tooling.

[0039] Alternatively, by turning the screw pin 63 counterclockwise and removing it, and then rotating the door 62 to open it, the metal slag stored inside can be easily cleaned through the slag discharge port 65.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
