Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by setting the polishing and grinding unit and the workpiece clamping mechanism to be in a straight line. After the workpiece is sharpened, the workpiece is polished as a whole by driving a cylindrical polishing nylon wheel with a polishing motor. This solves the technical problem that the device cannot polish the workpiece as a whole after it has been sharpened. Furthermore, by setting a feeding clamping unit to feed the sharpened and polished workpiece into the feeding frame, this solves the technical problem that the device cannot feed automatically and is not very convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency and high-precision automatic grinding device includes a support frame, a worktable at the upper end of the support frame, a workpiece clamping mechanism at the center of the front side of the upper end of the worktable, a groove at the center of the upper end of the worktable, a grinding mechanism at the upper end of the groove, a polishing and grinding unit at the rear end of the groove, a material unloading frame at the rear end of the polishing and grinding unit, guide rail frames on both sides of the upper end of the worktable, guide rails on one side close to each other at the upper end of the guide rail frames, a device block slidably connected to the guide rails, electric sliders on the left and right sides of the device block, and a material unloading clamping unit at the center of the device block.

[0007] As a preferred embodiment, the workpiece clamping mechanism has a clamping motor at its front end, a rotating shaft at the center of its rear end, a sleeve at the rear end of the rotating shaft, a silicone sleeve inside the sleeve, a fixed seat on the outer side of the center of the sleeve, the lower end of the fixed seat being fixedly mounted on the upper end of the worktable, and a bearing at the center of the upper end of the fixed seat being sleeved on the outer side of the sleeve.

[0008] As a preferred embodiment, the grinding mechanism has a cylinder on the left side, a transmission rod on the center of the right side of the cylinder, a transmission block fixedly connected to the right side of the transmission rod, a grinding motor on the upper end of the transmission block, a drive shaft on the center of the left side of the grinding motor, a grinding wheel on the left side of the drive shaft, and the main body of the grinding motor is placed obliquely on the upper end of the transmission block.

[0009] As a preferred embodiment, the polishing and grinding unit is provided with a second cylinder at its rear end, a second transmission rod at the center of the front end of the second cylinder, a second transmission block fixedly connected to the front end of the second transmission rod, a polishing motor at the upper end of the second transmission block, a rotating shaft at the center of the front end of the polishing motor, a cylindrical polishing nylon wheel at the front end of the rotating shaft, and the polishing and grinding unit is positioned in a straight line relative to the workpiece clamping mechanism.

[0010] As a preferred embodiment, the upper end of the unloading clamping unit is provided with a No. 3 cylinder, the lower end of the No. 3 cylinder is provided with a No. 3 transmission rod, and the lower end of the No. 3 transmission rod is provided with an electric gripper.

[0011] As another preferred embodiment, the inside of the feeding frame is provided with ramps on both sides, and the ramps are arranged symmetrically on the left and right.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, by setting the polishing and grinding unit and the workpiece clamping mechanism to be in a straight line opposite each other, after the workpiece grinding process is completed, the first cylinder will push the first transmission rod and push the first transmission block to the right. The grinding motor will move to the right at the same time as the first transmission block, making room for the operation of the polishing and grinding unit. Then the second cylinder will push out the second transmission rod, and the second transmission rod will push the second transmission block to send the polishing motor to the workpiece. The cylindrical polishing nylon wheel will completely wrap the workpiece as it is pushed forward. Then the polishing motor drives the cylindrical polishing nylon wheel to rotate, and the workpiece is polished as a whole, making the workpiece smooth and shiny, and increasing the quality of the finished workpiece.

[0014] (2) In this utility model, the workpiece is automatically unloaded after processing by setting up a feeding clamping unit. After the workpiece finishes the grinding and polishing process, the No. 3 cylinder of the feeding clamping unit will push out the No. 3 transmission rod. The No. 3 transmission rod will extend the electric gripper to the workpiece. The electric gripper converts the rotational motion into the linear motion of the gripper component through the internal transmission mechanism, realizing the opening and closing of the gripper to pick up the workpiece. After the electric gripper picks up the workpiece, the equipment block will slide to the rear feeding frame through the sliding connection with the guide rail. When it reaches the feeding frame, the electric gripper will release the workpiece, allowing the workpiece to fall into the feeding frame, realizing the automatic feeding process and increasing work efficiency.

[0015] (3) In this utility model, the workpieces are not stacked in the feeding frame by setting the ramps on both sides of the inside of the feeding frame symmetrically. After the feeding clamping unit feeds the workpieces, the workpieces will slide down the ramps to the left and right sides of the inside of the feeding frame, so that the workpieces will not be stacked too much in the middle of the feeding frame, reducing the manual intervention of the stacking process, improving efficiency and reducing manual operation.

[0016] In summary, this device has the advantages of increasing the quality of finished products, realizing automatic feeding process, increasing work efficiency, and reducing manual operation, and is especially suitable for the field of grinding machine production technology.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this utility model provides an efficient and high-precision automatic grinding device, including a support frame 1. The upper end of the support frame 1 is provided with a worktable 2. The front center of the upper end of the worktable 2 is provided with a workpiece clamping mechanism 3. The center of the upper end of the worktable 2 is provided with a groove 21. The upper end of the groove 21 is provided with a grinding mechanism 4. The rear end of the groove 21 is provided with a polishing and grinding unit 6. The rear end of the polishing and grinding unit 6 is provided with a material unloading frame 7. The upper sides of the worktable 2 are provided with guide rail frames 5. The upper ends of the guide rail frames 5 are provided with guide rails 51 close to each other. The guide rails 51 are slidably connected to the device block 52. The left and right sides of the device block 52 are provided with electric sliders. The electric sliders are slidably connected to the guide rails 51. The center of the device block 52 is provided with a material unloading clamping unit 53.

[0025] Furthermore, the workpiece clamping mechanism 3 has a clamping motor 31 at its front end and a rotating shaft 312 at its rear center. When the workpiece is fixed inside the sleeve 32, the clamping motor 31 drives the rotating shaft 312 to rotate. The rotation of the rotating shaft 312 simultaneously drives the sleeve 32 to rotate, and the rotation of the sleeve 32 drives the workpiece to rotate synchronously, ensuring the precision of the workpiece at the grinding point. The sleeve 32 is located at the rear end of the rotating shaft 312. A silicone sleeve is provided inside the sleeve 32 to ensure the stability of the workpiece inside the sleeve 32. A fixed seat 33 is fitted on the outer side of the center position of the sleeve 32. The lower end of the fixed seat 33 is fixedly mounted on the upper end of the worktable 2. A bearing is provided at the center of the upper end of the fixed seat 33. The bearing allows the sleeve 2 to rotate inside the fixed seat 33, ensuring both the stability of the workpiece rotation and the smoothness of the sleeve 32 rotation. The bearing is fitted on the outer side of the sleeve 32.

[0026] Furthermore, a cylinder 41 is provided on the left side of the grinding mechanism 4, and a transmission rod 412 is provided at the center of the right side of the cylinder 41. A transmission block 413 is fixedly connected to the right side of the transmission rod 412. When the workpiece is fixed, the cylinder 41 will extend and retract the transmission rod 412 to the left. The transmission block 413 will bring the grinding motor 43 closer to the workpiece to be ground as the transmission rod 412 extends and retracts. The grinding motor 43 is provided at the upper end of the transmission block 413. A drive shaft is provided at the center of the left side of the grinding motor 43. A grinding wheel 431 is provided on the left side of the drive shaft. The grinding motor 43 drives the drive shaft to rotate. The rotation of the drive shaft drives the grinding wheel 431 to rotate and grind the workpiece. The main body of the grinding motor 43 is placed obliquely on the upper end of the transmission block 413. The oblique placement of the grinding motor 43 ensures that the grinding wheel 431 contacts the front end of the workpiece for grinding.

[0027] Furthermore, the polishing and grinding unit 6 has a second cylinder 61 at its rear end, and a second transmission rod 612 at its front center. The front end of the second transmission rod 612 is fixedly connected to a second transmission block 613. A polishing motor 62 is mounted on the upper end of the second transmission block 613. A rotating shaft 621 is located at the front center of the polishing motor 62, and a cylindrical polishing nylon wheel 63 is located at the front end of the rotating shaft 621. The polishing and grinding unit 6 is linearly aligned with the workpiece clamping mechanism 3. After the workpiece sharpening process is completed, the first cylinder 41 will push the first transmission rod 412, thus moving the first... When the transmission block 413 is pushed to the right, the grinding motor 43 will move to the right simultaneously with the first transmission block 413, making room for the operation of the polishing and grinding unit 6. Then, the second cylinder 61 will push out the second transmission rod 612. The second transmission rod 612 will simultaneously push the second transmission block 613 to send the polishing motor 62 to the workpiece. As the workpiece is pushed forward, the cylindrical polishing nylon wheel 63 will completely wrap around it. Then, the polishing motor 62 will drive the cylindrical polishing nylon wheel 63 to rotate, performing overall polishing on the workpiece, making the workpiece smooth and shiny, and increasing the quality of the finished workpiece.

[0028] Furthermore, the upper end of the unloading clamping unit 53 is equipped with a third cylinder 531, the lower end of the third cylinder 531 is equipped with a third transmission rod 532, and the lower end of the third transmission rod 532 is equipped with an electric gripper 533. The electric gripper 533 is equipped with a motor and other power devices to drive the opening and closing operation of the electric gripper 533. When the workpiece finishes the grinding and polishing process, the third cylinder 531 of the unloading clamping unit 53 will push out the third transmission rod 532, and the third transmission rod 53... 2. The electric gripper 533 extends down to the workpiece. The electric gripper 533 converts the rotational motion into the linear motion of the gripper components through the internal transmission mechanism, realizing the opening and closing of the gripper to pick up the workpiece. After the electric gripper 533 picks up the workpiece, the device block 52 slides towards the rear unloading frame 7 through the sliding connection with the guide rail 51. When it reaches the unloading frame 7, the electric gripper 533 releases the workpiece, allowing the workpiece to fall into the unloading frame 7, realizing the automatic unloading process and increasing work efficiency.

[0029] Furthermore, the inside of the feeding frame 7 is provided with ramps 71 on both sides. The ramps 71 are symmetrically arranged on the left and right sides. After the feeding clamping unit 6 feeds the workpiece, the workpiece will slide down the ramps 71 to the left and right sides inside the feeding frame 7, so that the workpiece will not be piled up too much in the middle of the feeding frame 7, reducing the manual intervention of the stacking process, improving efficiency and reducing manual operation.

[0030] Working process: First, one end of the workpiece is fixed inside the silicone sleeve of the sleeve 32. The silicone sleeve ensures the stability of the workpiece inside the sleeve 32. After the workpiece is fixed, the first cylinder 41 will extend and retract the first transmission rod 412 to the left. The first transmission block 413 will move the grinding wheel of the grinding motor 43 closer to the workpiece to be ground as the first transmission rod 412 extends and retracts. Then, the clamping motor 31 will drive the rotating shaft 312 to rotate. The rotation of the rotating shaft 312 will simultaneously drive the sleeve 32 to rotate. The rotation of the sleeve 32 will drive the workpiece to rotate synchronously. At the same time, the grinding motor 43 drives the drive shaft to rotate. The rotation of the drive shaft drives the grinding wheel 431 to rotate, grinding the rotating workpiece. In the sharpening process, after the workpiece sharpening process is completed, cylinder 41 pushes transmission rod 412 to the right, pushing transmission block 413 to the right. Grinding motor 431 moves to the right along with transmission block 413, making room for the polishing grinding unit 6. Then, cylinder 61 pushes transmission rod 612 out, which pushes transmission block 613 to send polishing motor 62 to the workpiece. As it moves forward, cylindrical polishing nylon wheel 63 completely envelops the workpiece. The polishing motor 62 then drives the cylindrical polishing nylon wheel 63 to rotate, polishing the workpiece as a whole, making it smooth and shiny, and increasing the quality of the finished workpiece.

[0031] Secondly, after the workpiece finishes the grinding and polishing process, the third cylinder 531 of the unloading clamping unit 53 will push out the third transmission rod 532. The third transmission rod 532 will extend the electric gripper 533 down to the workpiece. The electric gripper 533 converts the rotational motion into the linear motion of the gripper component through the internal transmission mechanism, realizing the opening and closing of the gripper to pick up the workpiece. After the electric gripper 533 picks up the workpiece, the equipment block 52 will slide towards the unloading frame 7 at the rear end through the sliding connection with the guide rail 51. When it reaches the unloading frame 7, the electric gripper 533 will release the workpiece, allowing the workpiece to fall into the unloading frame 7. The workpiece will slide down the ramp 71 to the left and right sides inside the unloading frame 7, so that the workpiece will not be piled up too much in the middle of the unloading frame 7, reducing the manual intervention stacking process, improving efficiency, and reducing manual operation.
