Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically a CNC surface grinder. Background Technology

[0002] CNC grinding machines are machine tools that use CNC technology to grind the surface of workpieces using grinding wheels. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other grinding wheels and free abrasives such as oilstones, abrasive belts, honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines. Grinding machines can process materials with high hardness, such as hardened steel and cemented carbide; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very low surface roughness, as well as high-efficiency grinding, such as heavy-duty grinding.

[0003] A search revealed Chinese utility model patent CN219380070U, "A CNC High-Efficiency Surface Grinding Machine," which relates to the field of surface grinding technology. This utility model includes a bed with an internal cavity having an upper opening, a worktable located above the cavity, and a grinding assembly located above the worktable. The bed is equipped with a linear motion mechanism, which is fixed to the worktable. A support is mounted on the bed, and an electric push rod is installed on the support. The electric push rod is fixed to the grinding assembly. A water tank is mounted on the support, and a water pipe is installed on the water tank. One end of the water pipe is fixed to the grinding assembly and faces downwards from it. The worktable includes a base and a protrusion, with two opposite ends of the base positioned below its center.

[0004] The existing equipment has the following problems when in use: when grinding workpieces, the workpieces are clamped and fixed on the grinding machine and the angle cannot be adjusted. The processing angle of the workpieces needs to be adjusted manually, which increases the number of operation steps for workers, reduces the processing efficiency of workpieces, and the debris generated during processing is difficult to collect, which reduces the cleanliness of the grinding machine.

At this time, the machine bed is activated to process the workpiece. The workpiece remains stable during processing to avoid movement that would reduce the processing effect. When processing is completed, the electric telescopic rod drives the limit block to move. The limit block, in conjunction with the sensor, sends a signal to the microcontroller in the machine bed. At this time, the conveyor roller is activated to drive the workpiece to move, thereby processing the next part of the workpiece and improving the flexibility of workpiece processing.

[0010] Preferably, the conveying rollers are provided in several groups, and gaps are provided between the multiple groups of conveying rollers.

[0011] By adopting the above technical solution, gaps are provided to facilitate the falling of debris.

[0016] Preferably, the limiting block is made of rubber, and the sensor is a TF-NOVA lidar.

[0017] By adopting the above technical solution, the limiting block enhances the effect of fixing the workpiece.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The electric telescopic rod is activated to drive the limit block to clamp the workpiece, keeping the workpiece stable during processing and preventing movement that would reduce the processing effect. By using the conveyor roller in conjunction with the limit component, different parts of the workpiece can be moved for processing, improving the flexibility and efficiency of processing.

[0020] 2. During processing, the debris falls into the collection bag through the gap between the conveying rollers. The fan is activated to increase the debris absorption effect, preventing debris from adhering to the workpiece and affecting subsequent processing, thus maintaining the processing accuracy.

The electric telescopic rod 15 is activated to drive the limiting block 14 to clamp the workpiece. At this time, the machine bed 1 is activated to process the workpiece. The workpiece maintains stability during processing to avoid movement that would reduce the processing effect. The machine bed 1 is equipped with a microcontroller, which is electrically connected to the electric push rod 2, the electric telescopic rod 15, the sensor 4, and the fan 11. The limiting block 14 is made of rubber, and the sensor 4 is a TF-NOVA laser radar. When processing is completed, the electric telescopic rod 15 drives the limiting block 14 to move. The limiting block 14, in conjunction with the sensor 4, sends a signal to the microcontroller inside the machine bed 1. At this time, the conveyor roller 7 is activated to drive the workpiece to move, thereby processing the next part of the workpiece.

[0028] Please see Figure 1 , Figure 2 , Figure 4 The bottom chamber 8 has slots 9 on both sides, and a card plate 12 is engaged inside the slot 9. A collection bag 10 is connected to the bottom of the card plate 12. A fan 11 is installed at the bottom of the bottom chamber 8.

[0029] Working principle: The workpiece is placed on the conveyor roller 7. The conveyor roller 7 is started to move the workpiece. When the workpiece moves to below the processing head, the electric push rod 2 is started to drive the limiting component 5 to descend, so that the limiting block 14 contacts the workpiece. The electric telescopic rod 15 is started to drive the limiting block 14 to clamp the workpiece. At this time, the machine bed 1 starts to process the workpiece. The workpiece maintains stability during processing to avoid movement that would reduce the processing effect. When processing is completed, the electric telescopic rod 15 drives the limiting block 14 to move. The limiting block 14, together with the sensor 4, sends a signal to the microcontroller in the machine bed 1. At this time, the conveyor roller 7 is started to move the workpiece, so as to process the next part of the workpiece, which improves the flexibility of processing the workpiece. The debris generated during processing is blocked by the baffle 6 and falls into the collection bag 10 through the gap between the conveyor rollers 7. The fan 11 is started to increase the effect of debris collection and prevent debris from adhering to the workpiece and affecting subsequent processing. The door 13 is opened and the clamping plate 12 is pulled out of the clamping slot 9, so as to facilitate the collection and processing of debris.
