Description

TECHNICAL FIELD

[0001] The utility model relates to the device in the field of grinding wheel dressing, especially to a high-precision grinding wheel dressing equipment. BACKGROUND

[0002] Taking the most commonly used surface grinder as an example, the grinder can be divided into manual grinder, semi-automatic grinder and full-automatic grinder at present. The manual grinder and the semi-automatic grinder can only be repaired and dressed with the help of artificial and simple tools for the plane and simple curved surface, and the precision is not high and the efficiency is low.

[0003] The semi-automatic grinder and the full-automatic grinder are further divided into many kinds. Taking the most common numerical control machine type as an example, a repair and dressing tool (diamond pen) is fixed on the machine tool workbench surface, and the three coordinate axes (X / Y / Z) of the machine tool are controlled by the numerical control system of the grinder to repair and dress the plane or some relatively complex curved surface. The equipment is relatively high in price, and if higher precision and more complex shape are to be realized, more expensive configurations need to be added. For the existing inventory equipment, it is difficult to complete the complex repair and dressing work, and the cycle is long, and the sand wheel is usually repaired and dressed by customizing the repair and dressing device, but this way is high in cost, long in cycle, poor in precision control and unable to adjust.

[0022] See Figure 1 and Figure 2As shown in the figure, the high-precision grinding wheel dressing equipment includes: a main body 1, an X-direction translation structure, a Z-direction translation structure, a tool rotation structure, and a grinding wheel drive structure. The X-direction translation structure and the grinding wheel drive structure are fixed on the main body 1. The Z-direction translation structure is fixed on the X-direction translation structure. The movement direction of the Z-direction translation structure is perpendicular to the main body 1. The tool rotation structure is fixed on the Z-direction translation structure. The grinding wheel drive structure includes a support arm 22, a grinding wheel 23, and a universal grinding machine flange 24. The support arm 22 is vertically fixed on the main body 1. The top of the support arm 22 is vertically rotatably connected to a power spindle. The end of the power spindle is detachably connected to the universal grinding machine flange 24. The grinding wheel 23 is detachably connected to the universal grinding machine flange 24.

[0023] The X-axis translation structure includes a servo motor X-axis 2, a translation slider 4, a translation platform 5, and a translation guide rail 6. The translation slider 4 is installed on the X-axis moving device 3. The translation guide rail 6 is fixed on the main body 1. The top of the translation platform 5 is slidably connected to the top of the translation guide rail 6. The translation slider 4 is fixedly connected to the bottom of the translation platform 5. The main shaft of the servo motor X-axis 2 is slidably connected to the translation slider 4 through a lead screw.

[0024] The Z-axis translation structure includes a back plate 7, a vertical moving platform 8, a servo motor Z-axis 9, a vertical slider 10, and a Z-axis moving device 11. The back plate 7 is vertically mounted on the translation platform 5. The servo motor Z-axis 9 and the Z-axis moving device 11 are mounted on the back plate 7. The vertical slider 10 is located inside the Z-axis moving device 11. The main shaft of the servo motor Z-axis 9 is slidably connected to the vertical slider 10 through a lead screw. The vertical moving platform 8 is fixedly connected to the vertical slider 10.

[0025] The tool rotation structure includes a fixing screw hole 12, a fixing seat 13, a servo motor A-axis 14, a fixing platform 15, a synchronous pulley 16, a reducer 17, a swing arm 18, and a tool grinding structure. The fixing seat 13 is fixedly installed on the vertical moving platform 8 through the fixing screw hole 12. The servo motor A-axis 14 is fixedly connected to the fixing seat 13 through the fixing platform 15. The synchronous pulley 16 is connected to the output end of the servo motor A-axis 14 through a belt. The synchronous pulley 16 is connected to the reducer 17 through the rotating shaft inside the fixing seat 13. The reducer 17, the synchronous pulley 16, and the rotating shaft rotate coaxially. The output end of the reducer 17 is equipped with a swing arm 18, and the end of the swing arm 18 is fixed with a tool grinding structure.

[0026] The tool grinding structure includes a diamond pen holder 19 and a grinding tool 20. The diamond pen holder 19 is fixed to the end of the swing arm 18, and the grinding tool 20 is fixed on the diamond pen holder 19.

[0027] The reducer 17, synchronous pulley 16, and rotating shaft are all hollow through-hole structures, with an industrial camera 21 installed inside the through-hole. The center of the industrial camera 21 extends from the center through-hole of the reducer 17 and synchronous pulley 16 as a coaxial visual path. This structure ensures that the synchronous pulley 16, reducer 17, swing arm 18, diamond pen holder 19, and grinding tool 20 maintain a coaxial relationship with the industrial camera 21 and do not cause motion interference when they rotate.

[0028] The servo motor Z-axis 9 and servo motor X-axis 2 can move the mobile platform by moving the slider to achieve two-dimensional motion.

[0029] In this embodiment, various irregularly shaped grinding wheels or similar tools can be flexibly ground without the need for custom-made special tooling fixtures.

[0030] The vertical slider 10 and the horizontal slider 4 can be moved on the moving device via ball screws.

[0031] In this embodiment, the platform is made more stable during movement.

[0032] Among them, the reducer 17 can stabilize the power transmitted from the servo motor A-axis 14 to a certain value.

[0033] In this embodiment, accidents such as damage to the grinding tools caused by the swing arm moving at excessive speed are avoided.

[0034] Among them, the swing arm 18 can drive the diamond pen holder 19 under the drive of the motor, so that the grinding tool 20 can make an arc motion around the central axis of the reducer 17 with its top tip.

[0035] In this embodiment, the top of the grinding tool is always positioned at the center of the moving circle during movement, which not only improves the ability to grind various shapes but also ensures the continuity of the grinding process.

[0036] The grinding tool can be a commercially available or custom-made diamond pen, or a diamond disc with a drive mechanism that can rotate, or a similar structure.

[0037] Working Principle: Upon startup, the power spindle, vertically rotatably connected to the top of the support arm 22, is connected to the output of an external motor. After the machine tool starts, it can perform actions according to the motion steps programmed in G-code. The grinding part rotates in a circular motion, rubbing and cutting against the tip of the grinding tool 20. During operation, the swing arm 18, driven by the motor, moves the pen holder, causing the grinding tool 20 to rotate around its tip. With the assistance of an industrial camera, the tip of the grinding part on the top of the grinding tool 20 is adjusted to the center of its circular motion to ensure smooth subsequent processes. After debugging, the pre-prepared data is imported into the machine. Then, driven by the X and Z axes of the servo motors, the machine uses a translation platform and a vertical moving platform to transport the grinding device to the designated position. Next, according to the required grinding shape, the swing arm begins to move in an arc, continuously adjusting the posture of the grinding tool. Simultaneously, the industrial camera provides real-time feedback on the working status, observing not only whether the turned shape meets expectations but also whether the top position of the grinding tool has shifted. After the grinding is completed, the translation platform and the vertical moving platform will return to their initial positions under the drive of the servo motors, waiting for the next grinding object.

[0038] The grinding wheel drive structure is similar to the grinding machine spindle device, aiming for independent dressing, saving time, and allowing the grinding wheel dressing work for the next process to be prepared in advance during grinding operation. Specifically, a spindle device with the same structure as the grinding machine (which can be a fixed model or one with different tapers or models) is installed on the power spindle vertically rotatably connected to the top of the support arm 22. The grinding wheel is mounted on the grinding machine universal flange 24, which is connected to the power spindle. The motor drives the power spindle to rotate and complete the independent dressing. The dressed grinding wheel 23, along with the grinding machine universal flange 24, can be directly installed on the grinding machine spindle for use without loss of accuracy (negligible accuracy), thus improving machining accuracy.

[0039] This grinding wheel dressing equipment can flexibly handle the dressing needs of various irregularly shaped grinding wheels or tools for specific purposes. It improves versatility and adaptability, freeing operators from the need for complex and ever-changing specialized tooling fixtures, thus significantly shortening the work cycle. In terms of precision, it combines an advanced vision system and a fine adjustment mechanism to ensure the tool tip position is always at the predetermined center position, guaranteeing continuity and stability during dressing. The grinding wheel drive structure is similar to the grinding machine spindle device, allowing for independent dressing to save time and enabling the preparation of the next grinding wheel dressing operation in advance during grinding. The user-friendly interface is another highlight of this equipment. The control system can provide a graphical user interface according to different user needs, or accept internationally recognized G-code programming, which greatly reduces the learning curve, allowing even novice operators to quickly get started. Furthermore, this flexible programming method provides customized solutions for different machining tasks, enhancing the equipment's versatility.
