Description

Technical Field

[0001] This invention relates to surface grinders, and more particularly to a vertical CNC single-sided grinder. Background Technology

[0002] Grinding machines are needed for various flat metal and non-metal products that require rough and fine grinding, such as motorcycle and automobile brake pads and clutch discs. Existing grinding machines are mainly double-sided grinding machines, which are prone to insufficient precision during grinding.

[0003] At the same time, the existing grinding machine structure is relatively complex and is only suitable for a single model of product, with poor applicability to various flat metal and non-metal materials. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical CNC single-sided grinding machine that can effectively solve the problems of existing grinding machines being relatively complex and having poor general applicability.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a vertical CNC single-sided grinding machine, including a frame, a worktable mounted on the frame, a first drive motor mounted on one side of the frame and the first drive motor having a lead screw module mounted on its shaft, a third drive motor connected to the lead screw module that can move up and down with the first drive motor, and a grinding assembly including a grinding disc connected to the third drive motor that can rotate with the worktable; a product placement structure mounted below the grinding assembly on the worktable; a second drive motor mounted below the frame and the second drive motor having a lead screw module that can rotate with the worktable. A rotating turntable; a fixed block is set on the worktable, and the upper end of the fixed block is formed with a placement groove adapted to the turntable; the turntable can rotate within the placement groove; a discharge port is set below the discharge end of the turntable on the worktable, and a corresponding discharge device is set below the discharge port on the frame; the shaft of the second drive motor is connected to the turntable; a set of placement through holes with shapes matching the products to be processed are set on the turntable, and the placement through holes and the bottom of the placement groove cooperate to form a placement area for placing the products to be processed; a feeding device is set above the feed end of the turntable on the frame; the feeding device is adapted to the placement through holes.

[0006] To achieve simple and reliable feeding, the feeding device includes a feeding bracket mounted on the worktable, a feeding support plate mounted on the feeding bracket, a feeding hole on the feeding support plate, and a detachable feeding positioning frame mounted on the feeding support plate at the feeding hole position. The inner circle of the feeding positioning frame is concentric with the feeding hole. Two opposing feeding limit plates are mounted on the feeding positioning frame. The two feeding limit plates form a placement area adapted to the product to be processed, and the placement area is coaxial with the feeding hole.

[0007] To achieve simple and reliable material discharge, a discharge notch is provided on the worktable; the feed end of the discharge device is located below the discharge notch, and the feed end of the discharge device is equipped with a discharge guide structure adapted to the discharge notch; the discharge notch is U-shaped, and its spacing is larger than the size of the through hole.

[0008] For easy disassembly and replacement, the fixing block is composed of three detachable square steel plates, including a left fixing block, a transverse fixing block, and a right fixing block arranged sequentially along the discharge notch; the transverse fixing block is located below the grinding disc.

[0009] To facilitate disassembly and replacement, the turntable is circular in shape and is composed of N sector blocks of the same shape and size. Each sector block has a mounting hole. The mounting holes are distributed at equal intervals on the turntable, and their centers are located on the same circle concentric with the turntable.

[0010] To prevent the processed product from detaching from the through hole during operation, a limiting structure is provided on each side of the fixing block on the grinding disc. The limiting structure includes a limiting block that is detachably mounted on the fixing block. One end of the limiting block is mounted above the turntable, and a U-shaped notch is provided on the end of the limiting block facing the turntable. A rotatable roller is installed in the U-shaped notch. The roller and the upper surface of the turntable are fitted with a clearance.

[0011] To improve the overall sealing and dust removal effect, baffles are installed around the workbench, and the end of the feed support plate near the baffles is connected to the baffles; a turntable cover is installed above the turntable on the frame, and the turntable cover is hinged to the baffles, with a handle for opening and closing the turntable cover; the baffles are also equipped with an upper housing that is compatible with the first drive motor and the turntable; a set of dust suction ports are opened on the side plate, and a vacuum cleaner is connected to the dust suction ports.

[0012] Furthermore, the shaft of the second drive motor is connected to a clutch, and the turntable is mounted on the clutch. This prevents the second drive motor from being damaged by jamming.

[0013] In order to clean up debris and foreign matter in the through hole in a timely manner, a set of air blowing devices is installed on the fixing block. Each air blowing device includes an air blowing bracket and an air blowing block installed on the air blowing bracket. The end face of the air blowing block facing the through hole is provided with an air outlet. An air passage is provided inside the air blowing block and communicates with the air outlet. An air inlet is also provided on the air blowing pipe, and the air inlet is connected to an air pump via an air pipe.

[0014] Furthermore, the frame is also equipped with a manually rotatable rotating arm, on which a human-machine interface screen is mounted; the first drive motor, the second drive motor, and the human-machine interface screen are connected.

[0015] The beneficial effects of this invention are as follows: 1. The grinding assembly, consisting of a turntable and mounting through-holes, has a simple structure and can reliably and stably achieve single-sided grinding of circular flat parts. Simultaneously, the mounting groove, which matches the mounting through-holes, enables the positioning of the reference surface, improving grinding accuracy. The feed positioning frame is detachable and fixed at the feed hole position, facilitating the replacement of the corresponding feed positioning frame and its feed limit plate to accommodate different sizes, thus expanding the applicability of the entire grinding machine and meeting the processing needs of products of various sizes. The turntable has mounting through-holes that match the product to be processed, allowing for different shapes such as circles, squares, and other shapes that fit the product, satisfying the grinding needs of various flat metal and non-metal materials.

[0016] 2. Grinding is achieved by using through holes and grooves in conjunction with grinding components. The structure is relatively simple. At the same time, the through holes can be designed to be relatively large to meet the grinding needs of various round flat parts smaller than the through holes, thereby improving the applicability of the entire grinding machine.

[0017] 3. The U-shaped discharge notch, combined with the design of the through hole, has a simple structure and can reliably achieve material discharge.

[0018] 4. The fixing block consists of three square steel plates. Considering the need for flatness during grinding and wear, the horizontal fixing block can be easily replaced as needed. Compared to a one-piece design, disassembly and replacement are easier. Because the horizontal fixing block is more prone to replacement due to wear and other issues, replacing only the horizontal fixing block is less costly than replacing the entire fixing block.

[0019] 5. The turntable is designed with multiple equal parts for easier assembly and disassembly. It is divided into equal parts according to the product size; smaller products have more equal parts, improving processing efficiency.

[0020] 6. The turntable cover is hinged to the baffle, which makes it easy to open the turntable cover and to inspect the turntable position, while also achieving the sealing of the whole machine.

[0021] 7. Human-machine interface control panel, which facilitates adjustment of the working status of the first drive motor, second drive motor, third drive motor, air pump, clutch and vacuum cleaner as needed.

[0022] 8. The use of a clutch can prevent jamming and provide protection, thereby improving safety performance.

[0023] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. Attached Figure Description
