[0002] In the post-processing stage of industrial production, gate grinding is a critical step that directly affects product quality and subsequent processing. To improve the automation level and efficiency of gate grinding, an automatic gate grinding device for post-processing has been developed. This device aims to achieve efficient and precise automatic grinding of gates while optimizing the working environment and ensuring the continuity and stability of production.

[0003] In existing technologies, the commonly used mechanical structures are mostly simple motor-driven grinding heads, which are used in conjunction with manual or simple tooling fixtures to fix the workpiece. The technical principle is mainly to use a motor to drive the grinding head to rotate at high speed, and the operator manually adjusts the position of the workpiece to make the grinding head contact the gate for grinding. The accuracy and effect of grinding are controlled by human experience.

[0004] However, existing technologies lack effective dust prevention measures when grinding gates. The large amount of debris generated during grinding is easily scattered everywhere, which is not only difficult to collect but also causes serious pollution to the working environment. At the same time, the scattered debris also poses safety hazards, threatening the health and safety of operators. Therefore, an automatic grinding device for post-finishing gates is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic grinding device for post-finishing gates, which aims to improve the problems of debris splashing and collection difficulties during gate grinding in the prior art.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an automatic grinding device for post-finishing gates, comprising a base 1. The base 1 is a rectangular steel plate welded structure with a thickness of 8-12mm. Anti-slip rubber pads are welded at the four corners of the bottom to provide stable support for the entire device and prevent displacement due to vibration during grinding operations, thereby ensuring grinding accuracy. The base 1 is made of Q235 low-carbon steel, which has good strength and toughness, as is common knowledge and will not be described in detail here. A grinding cabinet 3 is fixedly connected to the top of the base 1. The grinding cabinet 3 is a closed cabinet structure made of stainless steel. An inspection door is opened on the side wall of the cabinet to accommodate the grinding components and form a closed working space to prevent grinding debris from spreading to the external environment. A grinder 8 is rotatably connected inside the grinding cabinet 3. The grinder 8 consists of a drive motor, a transmission spindle, and a diamond grinding head. The drive motor adopts a YE2 series three-phase asynchronous motor. The machine, with a power of 1.5-3kW, is used to drive the grinding head to rotate at high speed to achieve the effect of grinding the gate of the workpiece. This is existing technology and will not be described in detail here. The top of the grinding cabinet 3 is fixedly connected to the placement plate 6, which is made of 45# steel plate and the surface is milled and precision machined with a flatness error of ≤0.1mm. It is used to provide a flat installation benchmark for subsequent components. The top of the placement plate 6 is fixedly connected to the base plate 7, the top of the base plate 7 is fixedly connected to the fixing plate 11, and the top of the fixing plate 11 is fixedly connected to the fixing fixture 5. The fixing fixture 5 consists of a clamping cylinder and an arc-shaped jaw. The inner wall of the jaw is pasted with a wear-resistant rubber pad, which is used to clamp and fix the workpiece from the top to prevent the workpiece from shaking during grinding, thereby ensuring the grinding accuracy. The top of the fixing plate 11 is provided with a lower clamp 12, and the fixing plate 11 is provided with a disassembly and assembly component. The grinding cabinet 3 is provided with a dustproof component.

[0035] The dustproof assembly includes a dust collection plate 9, which is an inclined plate structure made of stainless steel with an inclination angle of 30°-45°. The bottom of the plate is fixedly connected to the inside of the grinding cabinet 3 by welding. The dust collection plate 9 is located at the bottom of the grinding side of the grinder 8 and is used to collect the debris generated during grinding. The inclined structure allows the debris to automatically slide to the designated collection area under the action of gravity, avoiding the accumulation of debris on the plate surface and thus improving the debris collection efficiency. The bottom of the dust collection plate 9 is fixedly connected to the inside of the grinding cabinet 3. The dust collection plate 9 is located at the bottom of the grinding side of the grinder 8 and is used to collect the debris generated during grinding. A duct 10 is fixedly connected to the outer wall of the dust collection plate 9. A protective plate 4 is fixedly connected to the outer wall of the grinding cabinet 3. The protective plate 4 is located inside the outer wall of the grinder 8 to prevent debris from splashing. Multiple dustproof plates 2 are rotatably connected to both sides of the grinding cabinet 3.

[0036] Reference Figures 3-5 The assembly and disassembly components include a locking block 19, which is a cuboid structure made of 40Cr alloy steel with a hardened surface, achieving a hardness of HRC50-55, providing excellent wear resistance and deformation resistance. The outer wall of the locking block 19 is located inside the fixing plate 11, which has a moving groove 20. The outer wall of the locking block 19 is slidably connected to the moving groove 20 and the lower clamp 12, which has a groove 14. The fixing plate 11 has a limiting groove 18. A connecting rod 15 is slidably connected inside the fixing plate 11. One end of the connecting rod 15 is fixedly connected to the outer wall of the locking block 19, and the other end is fixedly connected to a pressing block 13, which is a cylindrical structure with an outer wall sleeve. A rubber anti-slip sleeve is provided for the operator to press and apply force. The pressing action drives the connecting rod 15 to move synchronously, thereby controlling the position of the locking block 19. A limiting ring 16 is fixedly connected to the outer wall of the pressing block 13. The limiting ring 16 is a ring structure made of stainless steel, and its outer diameter is adapted to the inner diameter of the limiting groove 18. The outer wall of the limiting ring 16 is slidably connected to the inside of the limiting groove 18 to limit the sliding direction of the connecting rod 15 and prevent the connecting rod 15 from wobbling radially when moving. At the same time, it provides a force support point for the spring 17. The outer wall of the limiting ring 16 is slidably connected to the inside of the limiting groove 18. The connecting rod 15 is fitted with a spring 17. One end of the spring 17 is fixedly connected to the outer wall of the limiting ring 16, and the other end of the spring 17 is fixedly connected to the inner wall of the limiting groove 18.

[0037] Working principle: When the automatic gate grinding device is working, the workpiece to be ground is first fixed between the lower clamp 12 and the fixture 5 of the fixed plate 11. Then, the grinder 8 rotates in the grinding cabinet 3 to automatically grind the gate of the workpiece. During the grinding process, the protective plate 4 and the dustproof plate 2 prevent debris from flying, the dust collection plate 9 collects the debris generated by grinding, and the air duct 10 assists in further processing the debris to avoid polluting the environment. In this way, the device realizes automatic grinding. At the same time, through the dustproof design, it solves the problem of debris flying and collection difficulties during gate grinding, ensuring that the grinding operation is efficient and orderly.

[0038] Additionally, when placing different workpieces for grinding, the pressing block 13 can be pushed. At this time, the pressing block 13 will cause the connecting rod 15 to slide along a set trajectory, thereby pushing the locking block 19 to slide smoothly inside the moving groove 20, thus releasing the restriction on the lower clamp 12. Simultaneously, during the movement of the connecting rod 15, the limiting ring 16 will slide synchronously inside the limiting groove 18, thereby compressing the spring 17. Afterwards, the appropriate lower clamp 12 is precisely placed on top of the fixed plate 11, and then the pressing block 13 is released. The compressed spring 17 will then generate a rebound force, causing the locking block 19 to engage inside the lower clamp 12, thus achieving a secure fixation of the lower clamp 12. This allows for stable gate grinding operations on different workpieces in the future. This convenient assembly and disassembly method greatly improves the adaptability of the device to different workpieces and the efficiency of operation.
