Description

Technical Field

[0001] This invention relates to the field of blade sharpening equipment, and more specifically to a polishing blade sharpening device. Background Technology

[0002] In the machining industry, some precision workpieces with low surface roughness are often machined using finish cutters (turning instead of grinding) to improve machining accuracy. This also improves machining efficiency and reduces residual compressive stress on the surface, thereby enhancing wear resistance. Finish cutters typically use a low depth of cut and a large feed rate, resulting in the cutting edge of the finish cutter projecting as a continuous arc on the base surface. The radius of the arc is determined by the desired surface roughness and the feed rate. Based on r = (4Ra) 2 +f 2 The calculation is performed using 0.5 mm / 8Ra, where r is the tool radius (in mm), Ra is the desired surface roughness (in mm), and f is the feed rate (in mm / r). For example, if the surface roughness of the workpiece is to reach Ra0.4 after machining, and the feed rate is 1.5 mm / revolution, then r should be 468.875 mm. In other words, the radius of the finishing cutter should be no less than 469 mm to achieve the desired surface quality.

[0003] Chinese Patent (Publication No.: CN103567817A) discloses a shaft-type cutting tool grinding machine. The grinding assembly and tool feed assembly are connected and driven on a base plate. A grinding wheel on the grinding assembly, with vertical and adjustable feed angles, rotates in conjunction with a tool clamped in a chuck on a rotating slide of the tool feed assembly. This creates a spherical transmission deflection, shaping the tool's spherical cutting edge, front cutting edge, and rear cutting edge at various cutting angles. However, this method is not suitable for the arc-shaped grinding process of finishing cutters. During finishing cutter grinding, the vibration of the finishing cutter body is transmitted in reverse to the fixture. Fixture vibration easily affects the fixture's operational accuracy, causing deviation in the arc trajectory during grinding. This results in a significant deviation in the radius of the finishing cutter's arc, affecting the accuracy of the workpiece during cutting and causing force deviation in the finishing cutter, accelerating its wear. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a polishing knife sharpening device. This device utilizes the cooperation of an arc-shaped slider and an arc-shaped groove to establish the movement path of the fixture and the polishing knife on it, ensuring the stability of the fixture and the held polishing knife during sharpening. A rocker arm assembly serves as the linkage mechanism driving the arc-shaped slider, providing tangential guidance for the movement of the arc-shaped slider relative to the arc-shaped groove. This improves the accuracy and smoothness of the movement of the arc-shaped slider relative to the arc-shaped groove, and increases the response speed for adjusting the polishing knife sharpening position, thereby ensuring processing accuracy.

[0005] To solve the above problems, the following solution is adopted:

[0006] A blade sharpening device, comprising:

[0007] The guiding mechanism includes a slidingly fitted arc-shaped groove and an arc-shaped slider. The trajectory of the arc-shaped groove is arc-shaped, and the arc-shaped slider is equipped with a clamp. The arc-shaped groove is connected to the winding wheel through a traction cable, and the arc-shaped groove is installed on the slide plate through a translation mechanism.

[0008] The rocker arm assembly includes a rocker arm and a connecting rod. The two ends of the connecting rod are respectively hinged to the rocker arm. The rocker arm is rotatably connected to the slide plate, forming a double rocker arm mechanism with the slide plate as the frame. The connecting rod is connected to the arc-shaped slider and constrains the slider to move tangentially along the slide track.

[0009] The grinding tool, facing the clamping part of the fixture, is used to sharpen the polishing knife on the clamping part.

[0010] Furthermore, the arc-shaped groove includes a support plate and guide plates that are relatively spaced apart. The two guide plates are connected to the support plate to form a groove for accommodating the arc-shaped slider. The arc-shaped slider is located in the groove. The support plate supports the bottom surface of the arc-shaped slider. The side of the guide plate slides in cooperation with the side of the arc-shaped slider.

[0011] Furthermore, the side of the guide plate that is in contact with the arc-shaped slider is an arc surface, and a pressure plate is connected to the side of the guide plate away from the support plate. The pressure plate slides and fits against the top surface of the arc-shaped slider to keep the arc-shaped slider in the arc-shaped groove.

[0012] Furthermore, the take-up reel is rotatably mounted on the slide plate, one end of the traction cable is connected to one end of the arc-shaped slide groove, and the other end of the traction cable passes around the take-up reel and the driven wheel and is connected to the other end of the arc-shaped slide groove. The take-up reel, the traction cable, and the driven wheel together form a translation drive mechanism.

[0013] Furthermore, the axle of the take-up reel is rotatably mounted on the slide plate, and the axle of the take-up reel is connected to the take-up drive element.

[0014] Furthermore, the rocker arm is mounted on the slide plate via a rotating seat, and the connecting rod is fixed to the arc-shaped slider via a connecting seat, so that the connecting rod moves along the arc-shaped slide groove along with the slider.

[0015] Furthermore, the skateboard is provided with limiting components, which are respectively set at the starting and ending positions of the rocker's running trajectory to abut the rocker.

[0016] Furthermore, the translation mechanism includes a matching translation slider and a translation rail, with the translation rail distributed along the length direction of the polishing cutter.

[0017] Furthermore, the slide plate is mounted on the base plate via a feeding sliding mechanism, which includes a cooperating feeding slider and a feeding slide rail. The base plate is equipped with a feeding mechanism, which drives the slide plate to move relative to the base plate along the direction of the feeding slide rail.

[0018] Furthermore, the feed slide rail and the translation slide rail are spatially perpendicular in their distribution direction, and the mold is mounted on the base plate.

[0019] Compared with the prior art, the advantages and positive effects of this invention are:

[0020] (1) To address the problem of poor stability during the current grinding of polishing cutters, which leads to reduced machining accuracy, the movement path of the fixture and the polishing cutter on it is established by the cooperation of the arc-shaped slider and the arc-shaped groove, so as to ensure the stability of the fixture and the polishing cutter held therein during grinding. The rocker arm assembly is used as the linkage mechanism to drive the arc-shaped slider, which provides tangential guidance for the movement of the arc-shaped slider relative to the arc-shaped groove, improves the accuracy and smoothness of the movement of the arc-shaped slider relative to the arc-shaped groove, and improves the response speed of adjusting the grinding position of the polishing cutter, thereby ensuring machining accuracy.

[0021] (2) A pressure plate is configured for the arc-shaped slide to constrain the position of the arc-shaped slider and prevent the arc-shaped slider from coming out of the arc-shaped slide due to the vibration of the grinding wheel. Combined with the constraint of the rocker arm assembly, the stability of the arc-shaped slider movement is improved.

[0022] (3) The slide plate is installed on the base plate through the feed sliding mechanism, which allows the base plate and the corresponding polishing knife to be close to or away from the grinding tool, making it easier to control the grinding amount and improve the grinding accuracy.

[0029] Example 1

[0030] In a typical embodiment of the present invention, such as Figures 1-4 As shown, a light blade sharpening device is presented.

[0031] During the sharpening process of the polishing knife 2, the vibration of the polishing knife 2 body is transmitted in reverse to the fixture 3. This vibration not only affects the movement accuracy of the fixture 3, but also causes the arc trajectory during sharpening to deviate, resulting in a large deviation in the radius of the arc of the polishing knife 2. The deviation of the working position of the arc of the polishing knife 2 directly affects the accuracy of the workpiece being processed during cutting, reduces the overall machining quality, and also accelerates the wear rate of the polishing knife 2. Based on this, this embodiment provides a polishing knife sharpening device, which, through the precise cooperation of the arc-shaped slider 4 and the arc-shaped groove 5, and the guiding effect of the swing arm assembly, ensures the stability and accuracy of the polishing knife 2 during the sharpening process and reduces the impact of vibration on the sharpening accuracy.

[0032] like Figure 1 As shown, the sharpening device mainly includes a clamp 3, a guide mechanism, a rocker arm assembly, and a grinding tool 1. The guide mechanism includes a slidingly fitted arc-shaped groove 5 and an arc-shaped slider 4. The trajectory of the arc-shaped groove 5 is arc-shaped, and the arc-shaped slider 4 is fan-shaped. The arc-shaped groove 5 is also fan-shaped, and the length of the arc-shaped groove 5 along its arc-shaped trajectory is greater than the length of the arc-shaped slider 4, so that the arc-shaped slider 4 can slide along the arc-shaped trajectory of the arc-shaped groove 5. The sliding of this arc-shaped trajectory drives the clamp 3 to form the trajectory required during sharpening.

[0033] In order to hold the light knife 2, the arc-shaped slider 4 is provided with a clamp 3. The clamp 3 is provided with a clamping part for holding the light knife 2. The clamping part is provided with a positioning structure that matches the light knife 2, such as a positioning groove or a positioning block. The clamping part can also be configured according to the structure and size of the light knife 2.

[0034] Unlike the conventional method of directly driving the arc-shaped slider 4, in this embodiment, the arc-shaped groove 5 is used as the driving component, and the movement of the arc-shaped groove 5 drives the movement of the arc-shaped slider 4. The arc-shaped groove 5 is connected to the winding reel 10 via the traction cable 21, and the arc-shaped groove 5 is mounted on the slide plate 16 via the translation mechanism 6. When the winding reel 10 rotates, the traction cable 21 drives the arc-shaped groove 5 to translate relative to the slide plate 16. The direction of movement of the arc-shaped groove 5 is based on the direction of movement established by the translation mechanism 6.

[0035] Among them, such as Figure 3 and Figure 4 As shown, the traction cable 21 can be made of steel wire rope, metal wire, etc. Due to its flexibility, the traction cable 21 can bypass obstacles or be arranged according to complex paths, making it suitable for use in blade sharpening devices where space is limited or flexible layout is required. The flexible traction cable 21 can effectively transmit power, enabling the connection between the power source winding wheel 10 and the arc-shaped slide 5 of the actuator, thereby driving the arc-shaped slide 5 of the actuator to perform various movements, including the forward and backward movement of the arc-shaped slide 5.

[0036] The traction cable 21 can bypass the take-up reel 10 and the driven reel, connecting the two ends of the arc-shaped chute 5 to form a drive chain. When the power source (such as a motor) drives the take-up reel 10 to rotate, the traction cable 21 will move accordingly, thereby driving the arc-shaped chute 5 to move forward or backward along a predetermined path.

[0037] like Figure 2 As shown, the rocker arm assembly includes a rocker arm 11 and a connecting rod 13. The connecting rod 13 has two ends hinged to the rocker arms 11, which are rotatably connected to the slide plate 16, forming a double rocker mechanism 9 with the slide plate 16 as the frame. The connecting rod 13 is connected to the arc-shaped slider 4, constraining the slider to move tangentially along the slide track. When the double rocker mechanism 9 moves, the two rocker arms 11 rotate relative to the slide plate 16, and the two ends of the connecting rod 13 rotate relative to the connected rocker arms 11.

[0038] like Figure 3 As shown, the two rockers 11 in the dual rocker mechanism 9 are hinged to the two ends of the connecting rod 13 and rotatably connected to the slide plate 16. The rotation of the rocker 11 transmits force through the connecting rod 13, which connects the two rockers 11 and the arc-shaped slider 4. Its design ensures that the arc-shaped slider 4 always maintains the tangential direction along the track trajectory when moving, thus improving the accuracy and smoothness of the movement.

[0039] The dual-rocker mechanism 9 uses the slide plate 16 as its frame and achieves complex motion conversions through the cooperation of the rocker arm 11 and the connecting rod 13. When the arc-shaped slide 5 moves, because the direction of movement of the arc-shaped slide 5 is not completely consistent with the direction of the arc-shaped slider 4 constrained by the dual-rocker mechanism 9, when the arc-shaped slider 4 translates, the arc-shaped slider 4, constrained by the dual-rocker mechanism 9, rotates along the connecting rod 13 of the dual-rocker mechanism 9. This process is exactly the same as the direction of movement of the arc-shaped slider 4 along the arc-shaped slide 5, allowing the arc-shaped slider 4 to move along the arc-shaped track formed by the mutual slides, ensuring the stability and accuracy of the arc-shaped slider 4 during the sharpening process. The arc-shaped slider 4 can also drive the polishing knife 2 on the fixture 3 to form an arc-shaped motion trajectory, thereby forming the required sharpening path relative to the grinding wheel 1.

[0040] By ensuring the stability and accuracy of the finishing cutter 2 during the sharpening process and precisely controlling the sharpening parameters, the surface roughness and precision of the machined workpiece are significantly improved. This reduces stress deviation and wear on the finishing cutter 2 during sharpening, extending its service life.

[0041] The movement path of the fixture 3 and its polishing knife 2 is established by the cooperation of the arc-shaped slider 4 and the arc-shaped groove 5, which resists the uncontrollable deviation caused by vibration and ensures the stability of the fixture 3 and the polishing knife 2 during sharpening. The rocker arm assembly is used as the linkage mechanism to drive the arc-shaped slider 4, which provides tangential guidance for the movement of the arc-shaped slider 4 relative to the arc-shaped groove 5, improves the accuracy and smoothness of the movement of the arc-shaped slider 4 relative to the arc-shaped groove 5, and improves the response speed of adjusting the sharpening position of the polishing knife 2, thereby ensuring the processing accuracy.

[0042] like Figure 3 and Figure 4 As shown, the structure of the arc-shaped groove 5 and the arc-shaped slider 4 in this embodiment will be described in detail. The arc-shaped groove 5 consists of a support plate and guide plates that are spaced apart from each other. The two guide plates are connected to the support plate to form a groove that accommodates the arc-shaped slider 4.

[0043] The support plate carries the bottom surface of the arc-shaped slider 4, and the side of the guide plate slides in conjunction with the side of the arc-shaped slider 4 to ensure stable sliding of the slider within the groove. This provides a stable sliding path, enabling the arc-shaped slider 4 to move smoothly along a predetermined arc trajectory, improving the accuracy and smoothness of the movement, and reducing friction and wear.

[0044] The side of the guide plate that fits against the arc-shaped slider 4 is an arc surface, such as... Figure 4 As shown, the arc-shaped slider 4 is fan-shaped. The guide plate on one side of the arc-shaped slider 4 has an outwardly convex arc surface, and the guide plate on the other side of the arc-shaped slider 4 has an inwardly concave arc surface. The two arc surfaces are coaxially distributed to match the arc-shaped structures on both sides of the arc-shaped slider 4.

[0045] A pressure plate 22 is connected to the side of the guide plate away from the support plate. The pressure plate 22 slides and fits against the top surface of the arc-shaped slider 4. The support plate constrains the bottom surface of the arc-shaped slider 4 to keep it within the arc-shaped groove 5, preventing the arc-shaped slider 4 from dislodging from the groove during movement, thus increasing the stability and safety of the system. This ensures stable operation of the slider under high-speed or complex working conditions and reduces the failure rate.

[0046] To enable the movement of the arc-shaped chute 5 and the arc-shaped slider 4, a translation drive mechanism 7 is configured. The translation drive mechanism 7 includes a take-up reel 10, a driven reel, and a traction cable 21. The take-up reel 10 is rotatably mounted on the slide plate 16 and connected to both ends of the arc-shaped chute 5 via the traction cable 21. The traction cable 21 passes around the take-up reel 10 and the driven reel, connecting both ends of the arc-shaped chute 5 to form a drive chain. The driven reel cooperates with the take-up reel 10 to jointly drive the traction cable 21 to move. This achieves the translational movement of the arc-shaped chute 5, providing a power source for the movement of the arc-shaped slider 4, and enabling efficient and accurate translation of the arc-shaped chute 5.

[0047] The axle of the take-up reel 10 is mounted on the slide plate 16 and connected to the take-up drive element. The take-up drive element can be a servo motor, handwheel, etc., providing the power source for the rotation of the take-up reel 10, thus realizing the winding and unwinding of the traction cable 21. This makes the control of the translation drive mechanism 7 more flexible and adaptable to different working requirements.

[0048] like Figure 2 and Figure 3 As shown, the rocker arm 11 is mounted on the slide plate 16 via the rotating seat 12, and the connecting rod 13 is fixed to the arc-shaped slider 4 via the connecting seat 17, allowing the connecting rod 13 to move along the arc-shaped groove following the slider. This achieves mechanical linkage between the rocker arm 11 and the arc-shaped slider 4, converting the motion of the rocker arm 11 into the arc motion of the arc-shaped slider 4. This increases the flexibility and controllability of the mechanical structure, facilitating the realization of complex motion trajectories.

[0049] A limiting member 18 is disposed on the slide plate 16, located at the start and end points of the rocker arm 11's running trajectory, and is used to abut against the rocker arm 11. This prevents the rocker arm 11 from exceeding the predetermined range during movement, ensuring the safety and stability of the system. In this embodiment, the limiting member 18 can be a limiting screw. The threaded portion of the limiting screw mates with a pre-set threaded hole on the slide plate 16, and the end of the limiting screw is abutting end that contacts the rocker arm 11, which can abut against the rocker arm 11 and prevent the rocker arm 11 from moving further closer, improving the reliability and durability of the system and reducing damage caused by exceeding the range of motion.

[0050] Specifically, such as Figure 2As shown, the translation mechanism 6 consists of a translation slider 15 and a translation rail 14, which are distributed along the length direction of the grinding cutter 2. The translation slider 15 is installed on the bottom surface of the arc-shaped groove 5, and the translation rail 14 is arranged on the slide plate 16. The translation slider 15 and the translation rail 14 form a sliding engagement, thereby allowing the entire arc-shaped groove 5 to move along the direction of the translation rail 14.

[0051] The feed sliding mechanism consists of a feed slider 20, a feed slide rail, and a feed mechanism 19, which drives the slide plate 16 to move relative to the base plate 8 along the feed slide rail direction. The feed slide rail and the translation slide rail 14 are spatially perpendicular, forming a two-axis adjustment in the horizontal plane, which realizes the precise movement of the slide plate 16 in the first horizontal direction and the second horizontal direction, meeting complex machining requirements.

[0052] The feeding mechanism 19 can be a lead screw and slider mechanism. The two ends of the lead screw of the lead screw and slider mechanism are mounted on the base plate 8 through supports. The slider of the lead screw and slider mechanism is connected to the slide plate 16. The slider and the lead screw cooperate. When the lead screw rotates, the slider can drive the slider to move along the lead screw axis. By adjusting the rotation direction of the lead screw, the movement direction of the slider can be adjusted to realize feeding or retraction.

[0053] The mold 1 is mounted on the base plate 8 and works in conjunction with the translation mechanism 6 and the feed sliding mechanism on the slide plate 16 to complete the machining task. This ensures that the movement of the slide plate 16 in different directions does not interfere with each other, improving the stability and reliability of the system, making the entire mechanical structure more compact and reasonable, and improving machining efficiency and accuracy.

[0054] The grinding wheel 1 is selected based on the polishing tool 2 being sharpened. The grinding wheel 1 is driven by a corresponding rotary element, which can be an electric motor, stepper motor, etc. In this embodiment, a grinding wheel can be used. Grinding wheels are one of the most common grinding tools, made of abrasive and bonding agent, and have different grit sizes, hardness, and shapes, suitable for grinding various materials. When sharpening tools such as polishing tools 2, diamond grinding wheels or CBN (cubic boron nitride) grinding wheels are often used, as they have high hardness and wear resistance, and can maintain sharpness for a longer period.

[0055] Abrasive wheel 1 can also be made of abrasive belt. Belt grinding is a highly efficient and flexible grinding method suitable for machining flat, curved, and complex-shaped workpieces. Abrasive belts consist of abrasive, substrate, and binder, and have a wide range of grit sizes and different material options to meet various machining needs.

[0056] Grinding wheel 1 can also be a grinding disc, which is typically used for precision machining, such as mirror polishing. It uses fine-grained abrasives and performs micro-machining on the workpiece surface by rotation and pressure to achieve extremely high surface finish and smoothness.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
