Description

Technical Field

[0001] This utility model belongs to the field of CNC tool grinding technology, specifically relating to an intelligent robotic arm for a high-precision CNC tool grinding machine. Background Technology

[0002] CNC grinding machines are machine tools that use CNC technology to grind the surface of workpieces using grinding wheels. CNC grinding machines can be divided into CNC surface grinding machines, CNC centerless grinding machines, CNC internal and external cylindrical grinding machines, etc. They can process materials with high hardness, such as hardened steel and cemented carbide, as well as brittle materials, such as glass and granite. During the operation of a CNC grinding machine, a robotic arm is usually used to clamp and fix the workpiece.

[0003] Existing robotic arms used in CNC grinding machines have relatively simple structures and functions. Their movement direction is limited by the track, resulting in a limited range of motion. They are not easy to adjust according to the user's needs, have low work flexibility, and have a limited working range, which reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent robotic arm for a high-precision CNC tool grinder, in order to solve the problems mentioned in the background art, such as the limited structure and function of existing robotic arms for CNC grinders, the limited range of motion due to the restriction of their movement direction by the track, the inconvenience of adjustment according to the user's needs, low work flexibility, limited working range, and reduced work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a top frame with an open lower surface, a reciprocating screw rotatably mounted inside the top frame, one end of the reciprocating screw extending through the top frame, a motor mounted on the left side of the top frame, one end of the reciprocating screw fixedly connected to the output shaft of the motor, a slide block threaded onto the reciprocating screw, an electric push rod movably mounted on the lower surface of the slide block via a rotating assembly, a support plate mounted on the output shaft end of the electric push rod, two fixing plates I mounted on the lower surface of the support plate, two linkage plates rotatably mounted between the two fixing plates I, the linkage plates being arranged at an angle, a linkage arm hinged to the bottom end of the linkage plate, side plates mounted on both the left and right sides of the electric push rod, a fixing plate II mounted on the lower surface of the side plates, a fixing post mounted on the bottom end of the front side of the fixing plate II, the corner of the linkage arm rotatably mounted on the fixing post, and silicone pads mounted on opposite sides of the bottom ends of the two linkage arms.

[0006] By adopting the above scheme, a reciprocating screw, an electric push rod, a linkage plate, and a linkage arm are set up. The electric push rod drives the fixed plate to move, which works in conjunction with the linkage plate's hinged connection and the fixed column. The bottom end of the linkage arm is tightened, and the motor drives the reciprocating screw to rotate. The sliding block drives the electric push rod to move, thereby adjusting the position of the linkage arm. This expands the position of the linkage arm, making it easier to adjust according to the user's needs, improving work flexibility, and increasing work efficiency.

[0007] In the above scheme, it should be noted that both the motor and the electric push rod are electrically connected to an external power source.

[0008] In a preferred embodiment, the rotating assembly includes a support block, the lower surface of which is mounted on the lower surface of the slide, and a rotating column is rotatably mounted on the lower surface of the support block. The electric push rod is detachably mounted on the bottom end of the rotating column via a mounting assembly.

[0009] By adopting the above scheme, a support block and a rotating column are set up. The support block provides rotational support for the rotating column, and the rotating column provides support for the electric push rod. This allows the linkage arm to be adjusted in angle and position according to the user's needs, thereby increasing the applicability of the linkage arm and improving its convenience.

[0010] In a preferred embodiment, the mounting assembly includes a mounting cylinder with an open lower surface, the top end of the electric actuator is located inside the mounting cylinder, and four bolts are threaded onto the outer surface of the mounting cylinder, the tail ends of which are threadedly connected to the electric actuator.

[0011] By adopting the above scheme, the mounting cylinder and bolts are used to accommodate the top of the electric actuator. Combined with the bolts, the electric actuator is threadedly fixed to the mounting cylinder. This not only secures the electric actuator with threads, but also facilitates the disassembly of the electric actuator by loosening the bolts at any time later.

[0012] In a preferred embodiment, a telescopic rod is installed on the lower surface of both side plates, and the telescopic shaft of the telescopic rod is fixedly connected to the support plate.

[0013] By adopting the above solution, a telescopic rod is installed and fixed above the support plate using a side plate. The telescopic rod's extensibility strengthens the support plate, thereby improving its stability when moving up and down. This allows the support plate to firmly support the linkage plate and linkage arm.

[0014] In a preferred embodiment, a gear is mounted on the rotating column, and a toothed plate is slidably mounted on the lower surface of the support block via a sliding assembly. The toothed plate is located on the rear side of the rotating column and meshes with the gear.

[0015] By adopting the above scheme, by setting up a toothed plate and gears, and utilizing the action of the rotating column, the operator can easily rotate the linkage arm as needed, thereby adjusting the angle of the linkage arm. Combined with the meshing action of the gears and toothed plates, the position of the linkage arm after adjustment is fixed, thus preventing the linkage arm from rotating after adjustment.

[0016] In a preferred embodiment, the sliding assembly includes a U-shaped sliding rod, a fixing plate three is mounted on the rear side of the support block, the sliding rod is mounted on the lower surface of the fixing plate three, a sliding plate is slidably mounted on the sliding rod, and a toothed plate is mounted on the lower surface of the sliding plate.

[0017] By adopting the above scheme, by setting up a sliding rod and a sliding plate, the sliding rod is fixedly supported on the back of the support block by the function of the fixed plate three. Combined with the function of the sliding rod, the sliding plate provides sliding support for the sliding plate. The sliding plate provides fixed support for the toothed plate, so that the toothed plate can move left and right as the sliding plate slides, thereby providing stable sliding support for the toothed plate.

[0018] In a preferred embodiment, an operating lever is mounted on the left side of the toothed plate, and an operating plate is mounted on one end of the operating lever.

[0019] By adopting the above solution, by setting up an operating lever and an operating plate, and utilizing the function of the operating lever being fixed on the toothed plate, the operating plate drives the operating lever to move, thereby driving the toothed plate to move, so that the operator can easily move the toothed plate by operating the plate.

[0020] In a preferred embodiment, limiting channels are provided on both the front and rear sides of the top frame, and limiting plates are provided in the limiting channels. Both limiting plates are fixedly connected to the slide.

[0021] By adopting the above scheme, a limiting plate is set up, and one end of the limiting plate is located in the limiting channel to limit and support the slide, thereby enabling the slide to move stably left and right on the reciprocating screw, improving the stability and firmness of the slide during movement.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This high-precision CNC tool grinder's intelligent robotic arm is equipped with a reciprocating lead screw, electric push rod, linkage plate, and linkage arm. The electric push rod drives the fixed plate to move, which, in conjunction with the linkage plate's hinged connection and fixed column, is tightened at the bottom of the linkage arm. The motor drives the reciprocating lead screw to rotate, and the slide block drives the electric push rod to move, thus adjusting the position of the linkage arm. This expands the linkage arm's position, allowing for easy adjustment according to the user's needs, improving work flexibility, and enhancing work efficiency.

[0024] This intelligent robotic arm for high-precision CNC tool grinders uses support blocks and rotating columns. The support blocks provide rotational support for the rotating column, which in turn supports the electric push rod. This allows the linkage arm to be easily adjusted in angle and orientation according to user needs, thus increasing its applicability and improving convenience. Attached Figure Description

[0029] Please see Figure 1-3This utility model provides an intelligent robotic arm for a high-precision CNC tool grinder, including a top frame 1 with an open lower surface. The top frame 1 provides rotational support for a reciprocating screw 2. The reciprocating screw 2 is rotatably mounted inside the top frame 1, and the reciprocating screw 2 drives a slide block 4 to move. One end of the reciprocating screw 2 extends through the top frame 1. A motor 3 is mounted on the left side of the top frame 1, and the motor 3 drives the reciprocating screw 2 to rotate. One end of the reciprocating screw 2 is fixedly connected to the output shaft of the motor 3. The slide block 4 is threaded onto the reciprocating screw 2, and the slide block 4 fixes a support block 14. The lower surface of the slide block 4 is movably mounted with an electric push rod 5 via a rotating assembly. The electric push rod 5 provides fixed support for the side plate 6 and the support plate 7. The output shaft end of the electric push rod 5 is mounted with the support plate 7, which provides fixed support for the fixed plate 8. Two fixed plates 8 are mounted on the lower surface of the support plate 7, which provide movable support for the top of the linkage plate 9. Two linkage plates 9 are rotatably mounted between the two fixed plates 8, which provide movable support for the linkage arm 10. The linkage plates 9 are arranged at an angle. A linkage arm 10 is hinged at the bottom end to clamp and fix the workpiece. Side plates 6 are installed on both sides of the electric push rod 5 to fix and support the second fixing plate 13. The second fixing plate 13 is installed on the lower surface of the side plate 6 to fix and support the fixing column 11. The fixing column 11 is installed at the bottom of the front side of the second fixing plate 13 to provide rotational support for the bend of the linkage arm 10. The corner of the linkage arm 10 is rotatably mounted on the fixing column 11, and the bottom ends of the two linkage arms 10 are opposite each other. Silicone pads are installed on one side of the device. By setting up a reciprocating screw 2, an electric push rod 5, a linkage plate 9, and a linkage arm 10, the electric push rod 5 drives the fixed plate 8 to move, which is connected to the linkage plate 9 through the hinge and the fixed column 11. The bottom end of the linkage arm 10 is tightened. The motor 3 drives the reciprocating screw 2 to rotate, and the slide 4 drives the electric push rod 5 to move, thereby adjusting the position of the linkage arm 10. This expands the position of the linkage arm 10, making it easier to adjust according to the user's needs, improving work flexibility and efficiency.

[0030] The rotating assembly includes a support block 14, which provides rotational support for the rotating column 15. The lower surface of the support block 14 is mounted on the lower surface of the slide block 4, and the rotating column 15 is rotatably mounted on the lower surface of the support block 14. The rotating column 15 provides fixed support for the mounting cylinder 16. The electric push rod 5 is detachably mounted on the bottom end of the rotating column 15 through the mounting assembly. By setting the support block 14 and the rotating column 15, the support block 14 provides rotational support for the rotating column 15, and the rotating column 15 provides support for the electric push rod 5. This allows the linkage arm 10 to be adjusted according to the user's needs, thereby increasing the applicability of the linkage arm 10 and improving its convenience.

[0031] The mounting assembly includes a mounting cylinder 16 with an open lower surface, which accommodates and encloses the top end of the electric push rod 5. The top end of the electric push rod 5 is located inside the mounting cylinder 16. Four bolts 17 are threaded on the outer side of the mounting cylinder 16, which are used to thread-fix the electric push rod 5. The tail end of the bolts 17 is threadedly connected to the electric push rod 5. By setting up the mounting cylinder 16 and the bolts 17, the top end of the electric push rod 5 is accommodated by the mounting cylinder 16, and the electric push rod 5 is threadedly fixed to the mounting cylinder 16 by the bolts 17. This not only thread-fixes the electric push rod 5, but also facilitates the later disassembly of the electric push rod 5 by loosening the bolts 17.

[0032] Telescopic rods 12 are installed on the lower surfaces of both side plates 6. The telescopic rods 12 provide auxiliary support for the support plate 7, improving its stability. The telescopic shaft of the telescopic rods 12 is fixedly connected to the support plate 7. By setting the telescopic rods 12, the side plates 6 fix the telescopic rods 12 above the support plate 7. Combined with the extensibility of the telescopic rods 12, the support plate 7 is reinforced, thereby improving the stability of the support plate 7 when it moves up and down, so that the support plate 7 can firmly support the linkage plate 9 and the linkage arm 10.

[0033] A gear 25 is installed on the rotating column 15. A toothed plate 22 is slidably installed on the lower surface of the support block 14 through a sliding component. The toothed plate 22 meshes with the gear 25. The toothed plate 22 is located on the rear side of the rotating column 15. By setting the toothed plate 22 and the gear 25, and utilizing the function of the rotating column 15, the operator can easily rotate the linkage arm 10 as needed, thereby adjusting the angle of the linkage arm 10. Combined with the meshing of the gear 25 and the toothed plate 22, the position of the linkage arm 10 after adjustment is fixed, thereby preventing the linkage arm 10 from rotating after adjustment.

[0034] The sliding assembly includes a U-shaped slide bar 20, which provides sliding support for the slide plate 21. A fixing plate 3 19 is installed on the rear side of the support block 14, which provides fixed support for the slide bar 20. The slide bar 20 is installed on the lower surface of the fixing plate 3 19, and the slide plate 21 is slidably mounted on the slide bar 20. The slide plate 21 provides fixed support for the toothed plate 22, which is installed on the lower surface of the slide plate 21. By setting up the slide bar 20 and the slide plate 21, the fixing plate 3 19 fixes the slide bar 20 to the rear side of the support block 14. The slide bar 20 provides sliding support for the slide plate 21, and the slide plate 21 provides fixed support for the toothed plate 22, allowing the toothed plate 22 to move left and right as the slide plate 21 slides, thus providing stable sliding support for the toothed plate 22.

[0035] An operating lever 23 is installed on the left side of the toothed plate 22. The toothed plate 22 is moved by the operating lever 23. An operating plate 24 is installed on one end of the operating lever 23. The operating lever 23 is moved by the operating plate 24. By setting up the operating lever 23 and the operating plate 24, and by using the function of fixing the operating lever 23 on the toothed plate 22, the operating plate 24 drives the operating lever 23 to move, thereby driving the toothed plate 22 to move. This allows the operator to easily move the toothed plate 22 by operating the plate 24.

[0036] Limiting channels are provided on both the front and rear sides of the top frame 1. Limiting plates 18 are placed in the limiting channels. The limiting plates 18 are installed in the limiting channels and used to limit and support the slide block 4. Both limiting plates 18 are fixedly connected to the slide block 4. By setting the limiting plates 18, the slide block 4 is limited and supported by the fact that one end of the limiting plate 18 is located in the limiting channel. This allows the slide block 4 to move stably left and right on the reciprocating screw 2, improving the stability and firmness of the slide block 4 when it moves.

[0037] In use, the top frame 1 is fixed in the designated position, and then the electric push rod 5 is started. The output shaft of the electric push rod 5 drives the support plate 7 to move downward. The support plate 7 drives the fixed plate 8 to move downward. The fixed plate 8 drives the top of the linkage plate 9 to move downward. As the linkage plate 9 and the fixed plate 8 rotate, the linkage plate 9 gradually tilts as the fixed plate 8 moves. At this time, the bottom end of the linkage plate 9 drives the top end of the linkage arm 10 to open to both sides. Due to the rotational connection between the bend of the linkage arm 10 and the fixed column 11, the top end of the linkage arm 10 opens outward, and the bottom end of the linkage arm 10 moves towards the middle to clamp and fix the workpiece. Then, the electric push rod 5 is turned off, and the motor 3 is started. The motor 3 drives the reciprocating screw 2 to rotate. When the reciprocating screw 2 rotates, it drives the slide 4 to move. When the slide 4 moves, it drives the support block 14 to move. The support block 14 drives the rotating column 15 to move. The rotating column 15 drives the electric push rod 5 to move through the mounting cylinder 16. The position of the workpiece is then adjusted. After adjustment, motor 3 is turned off. When the angle of the linkage arm 10 needs to be changed, the operating plate 24 is moved. The operating plate 24 drives the operating lever 23 to move. The operating lever 23 drives the toothed plate 22 to move. When the toothed plate 22 moves, it drives the slide plate 21 to slide on the slide rod 20. With the meshing of the toothed plate 22 and the gear 25, the gear 25 is driven to rotate as the toothed plate 22 moves. The gear 25 drives the rotating column 15 to rotate. The rotating column 15 drives the mounting cylinder 16 to rotate. The mounting cylinder 16 drives the electric push rod 5 to rotate. The electric push rod 5 drives the support plate 7 and the fixed plate 8 to rotate, thereby adjusting the angle of the linkage arm 10. When the support plate 7 moves downward, it stretches the telescopic rod 12. Combined with the extensibility of the telescopic rod 12, the support plate 7 is strengthened, thereby improving the stability of the support plate 7 when it moves up and down, so that the support plate 7 can firmly support the linkage plate 9 and the linkage arm 10.
