Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and specifically to a grinding machine for image monitoring of grinding wheel profile. Background Technology

[0002] An optical projection grinder is a machine tool that uses a grinding wheel to grind the surface of a product and is equipped with an optical projection device. The optical projection device on an existing optical projection grinder consists of a display screen and an image capturing component. The image capturing component is fixed on one side of the worktable and is used to capture the grinding process of the product being processed and accurately project the image onto the display screen. The operator uses a convex lens mounted on the display screen that can move up, down, left, and right to magnify and observe the projected image, thereby improving the control of the accuracy of the workpiece processing.

[0003] In practical applications, the existing optical projection grinding machines described above cannot accurately monitor the contour accuracy of the grinding wheel because their image capturing components are fixed to one side of the worktable. Operators must rely on experience to judge whether the contour accuracy of the grinding wheel meets the standards, which has low accuracy. The contour accuracy of the grinding wheel directly affects whether the processing accuracy, surface finish, and other parameters of the processed product are up to standard. This leads to a significant decrease in the product yield and may even result in batches of products being scrapped, which not only reduces processing efficiency but also increases processing costs.

Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0020] like Figure 1-4 As shown, the present invention provides a grinding machine for image monitoring of grinding wheel profile, including a machine base 1, a worktable 2, an upper frame 3, a grinding assembly 4, and an image capturing mechanism 5; the worktable 2 and the upper frame 3 are respectively provided on the front and rear ends of the machine base 1; the grinding assembly 4 is provided on the front side of the upper frame 3 through a Z-axis drive assembly; the image capturing mechanism 5 includes a three-axis displacement assembly 51 and an image capturing assembly 52; the image capturing assembly 52 is provided on the side of the upper frame 3 through the three-axis displacement assembly 51; and the image capturing mechanism 5 is electrically connected to an external control system.

[0021] In this embodiment, the external control system is preferably a computer, which allows staff to intuitively and accurately observe the processing process and its status.

[0022] The three-axis displacement assembly 51 consists of a Z-axis linear module 511, a Y-axis linear module 512, and an X-axis linear module 513. The Z-axis linear module 511 is vertically bolted to the side of the upper frame 3. The Y-axis linear module 512 is horizontally bolted to the working end of the Z-axis linear module 511. The X-axis linear module 513 is horizontally bolted to the working end of the Y-axis linear module 512. An image capturing assembly 52 is bolted to the working end of the X-axis linear module 513. The three-axis displacement assembly drives the image capturing assembly to perform three-axis reciprocating motion, which facilitates the imaging and projection of the products being processed on the worktable and the grinding wheel.

[0023] The image capturing component 52 consists of an image capture device 521 and a protector 522 for protecting the image capture device 521. The image capture device 521 is fixed to the working end of the X-axis linear module 513 by base plate bolts. The working end of the image capture device 521 faces the worktable 2. The protector 522 is located on the working end of the image capture device 521. When the image capture device 521 captures and projects images of the products and grinding wheels being processed on the worktable, the protector 522 is in the open state. After the image capture device 521 finishes capturing and projecting images, the protector is in the closed state, thus protecting the working end of the image capture device 521 without interfering with it.

[0024] The protector 522 includes a mounting base 5221, a protective plate 5222, and a first driving device 5223. The mounting base 5221 is bolted to the working end of the image capture device 521. A protective groove is laterally formed on the mounting base 5221, and a shooting hole is formed on the bottom surface of the protective groove. The protective plate 5222 is movably arranged in the protective groove. The first driving device 5223 is fixed to the side of the image capture device 521 by a bracket bolt. The working end of the first driving device 5223 is bolted to the protective plate 5222. The first driving device is preferably a cylinder. The first driving device drives the protective plate to open or close the shooting hole.

[0025] The worktable 2 includes a sliding base 21, a Y-axis drive assembly 22, a machining table 23, and an X-axis drive assembly 24. The sliding base 21 is mounted on the machine base 1 via the Y-axis drive assembly 22, and the machining table 23 is mounted on the sliding base 21 via the X-axis drive assembly 24. The machining table 23 is provided with tooling fixtures for fixing the processed products, including but not limited to electromagnetic chucks and grippers in this embodiment.

[0026] The grinding assembly 4 includes a lifting seat 41, a grinding wheel spindle 42, a grinding wheel 43, and a second drive device. The lifting seat 41 is mounted on the front side of the upper frame 3 via a Z-axis drive assembly. The grinding wheel spindle 42 is fixedly mounted on the lifting seat 41. The grinding wheel 43 is rotatably connected to the front end of the grinding wheel spindle 42. The rear end of the grinding wheel spindle 42 is driven and connected to the output end of the second drive device located in the upper frame 3. In this embodiment, the second drive device is preferably a motor. The grinding assembly and the worktable cooperate to achieve three-axis precision machining.

[0027] The X-axis drive assembly 24, Y-axis drive assembly 22 and Z-axis drive assembly are all covered with dustproof folded cloths; specifically, the dustproof folded cloths can stretch or contract as the sliding seat 2 moves to maintain airtightness and prevent dust from entering the interior and affecting its accuracy.

[0028] The Y-axis drive assembly 22 consists of a slide rail, a servo motor, and a ball screw. The slide rail is bolted longitudinally to the base 1 and slidably connected to a sliding seat 21. The ball screw is bolted to the base 1 and its working end is fixedly connected to the bottom surface of the sliding seat 21. The servo motor is bolted to the base 1 and its output end is driven by the ball screw. This enables the Y-axis movement function.

[0029] The X-axis drive assembly 24 and the Z-axis drive assembly have the same structure as the Y-axis drive assembly 22, the difference being the installation position and direction, so they will not be described again.

[0030] The base 1 is provided with multiple adjustable brackets on its bottom surface to improve adaptability.

[0031] Working principle: First, the product or workpiece to be processed is placed in the tooling fixture on the processing table. The external control system drives the image camera to move along the X, Y, Z linear modules to a suitable position through the three-axis displacement component and takes pictures of the product to be processed and the contour of the grinding wheel respectively. After the pictures are taken, the images are projected and uploaded to the external control system. The image camera then resets and moves along the X, Y, Z linear modules to a safe stop point, and the grinding machine can start grinding the product to be processed.

[0032] After the product is finished, the external control system drives the image camera to move along the X, Y, and Z linear modules to a suitable position through the three-axis displacement component, and takes pictures of the finished product and the processed grinding wheel profile respectively. After the pictures are taken, the images are projected and uploaded to the external control system. The external control system compares the pictures taken before and after processing through comparison software, and can obtain the specific parameters of the product and grinding wheel profile. This provides a more intuitive and accurate reminder to the staff whether the product meets the processing requirements and whether the grinding wheel profile accuracy can continue to be processed.

[0033] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
